Human Adipose Tissue: Purinergic Receptor Involvement
Authors: Muhsin Khalfa Hydar , Al-Msaid M L Haider
Published: July 2020

Adipose tissue is derived from the pluripotent mesenchymal cells and further on from cells of the reticular connective tissue, which can produce lobes of fatty tissues like grapes. The reticulum cells store fat droplets that will finally conjoin to one large drop. In the process, the cells become rounder. Extrinsic signaling mechanisms control the cell fate and determination of progenitor cells. Extrinsic signals such as neurotransmitters and neurotrophins have a significant impact on the production and fate or progenitor cells. In addition to intrinsic regulators, extrinsic signaling systems such as neurotransmitters, play a fundamental role in the control of cell proliferation. Purinergic receptors are actively seen at an early stage of development in the germal layer at the embryonic stage.
Aim: This project aims to investigate the presence of purinergic signaling on human adipose tissue. Examine the essential histology of the human adipose tissue through routine histology and scanning electron microscopy.
Materials and Methods: Human adipose tissues were obtained from routine autopsy at AL-Hilla mortuary. Hematoxyline and eosin staining were processed on microtome sectioned slides. Tissues were also examined using scanning electron microscopy SEM. Immunohistochemistry of purinergic receptors (P2Y1, P2Y2, P2Y4) was examined in human adipose tissue.
Results: Histological examination/n of adipose tissue shows mature adipocytes with the lateral location of the nucleus. Purinergic receptors P2Y1, P2Y2, and P2y4 are seen on membranes of adipocytes. PCR product of digested adipose tissues also shows clear bands for all three purinergic receptors in human adipose tissue.
Conclusion: This study shows that mature adipocytes are an excellent source of pluripotent stem cells that are capable of proliferating and differentiating into other cell lineages through purinergic receptor activation using various purine pharmacology. Purinergic receptors are a good indicator of the presence of mesenchymal stem cells.

Appearance for the first time from Wuhan, China, the SARS-CoV-2 rapidly outbreaks worldwide and causes a serious global health issue. The effective treatment for SARS-CoV-2 is still unavailable. Therefore, in this work, we have tried to rapidly predict a list of potential inhibitors for SARS-CoV-2 main protease (Mpro) using a combination of molecular docking and fast pulling of ligand (FPL) simulations. The approaches were initially validated over a set of eleven available inhibitors. Both Autodock Vina and FPL calculations adopted good consistent results with the respective experiment with correlation coefficients of R_Dock=0.72 ± 0.14 and R_W = -0.76 ± 0.10, respectively. The combined approaches were then utilized to predict possible inhibitors, which were selected from a ZINC15 sub-database, for SARS-CoV-2 Mpro. Twenty compounds were suggested to be able to bind well to SARS-CoV-2 Mpro. The obtained results probably lead to enhance COVID-19 therapy.

El trabajo problematiza sobre las contradicciones entre un discurso que propone que la comunicación en las comunidades indígenas maya-tojolabales de Chiapas y las del estado de Oaxaca es representativa de un tipo de democracia superior y evidencia sobre la inequidad y violencia de género presente en dichas comunidades. El análisis se basa en la necesidad de develar la posible contribución de este discurso a la dominación que viven las mujeres en ellas o, por el contrario, a su liberación, y se realiza a partir de un enfoque de género. La metodología utilizada proviene del análisis crítico del discurso. Los resultados revelan una ideología patriarcal en el discurso analizado, que no invalida sus aportaciones a la construcción de una sociedad de la comunicación, sobre todo debido a que la comunicación comunitaria descrita por aquél puede servir de modelo para el resto de los niveles del sistema social.

Objective – to study the prevalence, clinical manifestations, features of diagnostics and effectiveness of treatment of rare arteriovenous spinal fistulas.Materials and methods. From 2004 to 2019 in SO «Scientific-practical Center of endovascular neuroradiology NAMS of Ukraine» were examined and treated 43 patients with spinal dural arteriovenous fistulas (DAVF) – type I arteriovenous malformations according to the Anson and Spetzler classification (1992). Only 2 (4.6 %) patients had an afferent effusion from the internal iliac artery with fistula at L5-S1 level. Magnetic resonance imaging and spinal selective subtraction angiography were used to diagnose arteriovenous fistulas. Liquid cyanoacrylate embolizant and transfemoral access were used for endovascular intervention, and posterior median access and single-level hemilaminectomy for microsurgical intervention.Results. Total DAVF exclusion from blood flow was achieved in both patients. One patient underwent microsurgical separation of DAVF, the other one was operated by a combination of endovascular and microsurgical techniques. Neurological improvement in the postoperative period was noted in both patients.Conclusions. Arteriovenous fistulas are diverse in clinical manifestations and radiographs. Verification of venous hypertensive myelopathy with the presence of pronounced perimedullary vessels on data of magnetic resonance imaging is the most specific feature of DAVF. If standard spinal angiography does not allow DAVF afferents to be verified it should be supplemented by selective catheterization of the internal iliac arteries, from where the arterial fistula can originate. The study of angioarchitectonics of arteriovenous fistula, according to angiography, makes it possible to choose surgical treatment to ensure effective and radical separation of arteriovenous fistula.

Published: July 2020

Objective ‒ to evaluate peculiarities and results of microsurgical treatment of intracranial dural arteriovenous fistulas (DAVF).Materials and methods. A retrospective analysis of microsurgical treatment of 7 patients with DAVF (4 (57. 1%) women and 3 (42.9 %) men, average age ‒ 43.4 years), who were hospitalized and surgically treated at the SO «Scientific-practical Center of endovascular neuroradiology NAMS of Ukraine» from 2016 to 2020, was made. DAVF was drained into the superior sugittal sinus in 4 (57.1 %) patients, transverse and sigmoid sinuses in 2 (28.6 %) cases, in the middle cranial fossa in 1 (14.3 %). According to the Cognard classification there were 3 (42.9 %) DAVFs belong to type IIb, 2 (28.6 %) ‒ to type IIa + b, 1 (14.3 %) DAVF ‒ to type II, 1 (14.3 %) DAVF ‒ to type IV.Results. In 3 (42.9 %) patients were primarily treated with endovascular method. Follow up studies revealed a recurrence of the disease, and microsurgical disconnection was performed. In 4 (57.1 %) cases, endovascular access to superficial DAVF was risky due to anatomical features, and microsurgery was preferred. In all patients, surgical treatment aimed the disconnecting of the shunt. In 1 (14.3 %) case of DAVF the transverse sinus was ligated. In all cases angiographic confirmation of the DAVFs exclusion was performed. In the postoperative period, there was no evidence of an increasing of clinical symptoms. All patients with pulsatile tinnitus and headache noted their regression after surgery.Conclusions. Considering the efficacy of modern endovascular techniques, microsurgery of DAVF has been indicated in cases where endovascular embolization has proven to be no-n-efficient or technically impossible. Among surgical methods of DAVF treatment, there are disconnection of the meningeal arteries directly at the site of the fistula, resection of the abnormal dura mater with feeding vessels, ligation and intersections of the injured venous sinus, skeletonization of the sinus with the feeding dural vessels. Treatment should be performed in all cases of DAVF with cortical venous drainage and progressive symptoms of the disease. The choice of optimal treatment should be made in a multidisciplinary manner, and all possible methods should be taken into consideration.

A case of endovascular treatment of a patient with a large false aneurysm of the splenic artery resulting from arrosion of its wall into the cavity of a previously existing pancreatic pseudocyst is described. In addition to the rather rare occurrence of this pathology, a feature of this clinical case was the patient’s sharp tortuosity of the access vessels, including the iliac arteries, abdominal aorta, and the splenic artery. Thus, both the endovascular prosthetics of the affected splenic artery and its embolization according to the traditional method using standard angiographic catheters and Gianturco coils turned out to be technically impossible because of the inability to reach the lesion site, especially with access through the common femoral artery that typical for such interventions, which was used by us when performing diagnostic selective arteriography. The second stage was the embolization of the splenic artery by access through the left axillary artery by means of conducting of guiding catheter into the celiac trunk. Through the lumen of this catheter, we introduced a microcatheter, through which detachable microcoils (usually used in interventional neuroradiology) were introduced into the splenic artery proximal and distal to the aneurysm cavity. As a result, the affected area of ​​the splenic artery with aneurysm was completely turned off from the bloodstream and thrombosed, that allowed to avoid extremely risky open surgical intervention and eliminated the risk of rupture of the aneurysm. Medication support included hypotensive therapy to reduce the risk of rupture of the aneurysm (before and after surgery), analgesics for the relief of post-embolization pain, and antibiotics for the prevention of infectious complications associated with pancreatitis and the possible development of spleen infarction. Monitoring the effectiveness of the intervention in the postoperative period was carried out using ultrasound dopplerography.
Tracking the New Zealand English NEAR/SQUARE merger using functional principal components analysis
Authors: Gubian M , Harrington J , Stevens M , Schiel F , Warren Paul
Published: July 2020

Copyright © 2019 ISCA The focus of the study is the application of functional principal components analysis (FPCA) to a sound change in progress in which the SQUARE and NEAR falling diphthongs are merging in New Zealand English. FPCA approximated the trajectory shapes of the first two formant frequencies (F1/F2) in a large acoustic database of read New Zealand English speech spanning three different age groups and two regions. The derived FPCA parameters showed a greater degree of centralisation and monophthongisation in SQUARE than in NEAR. Compatibly with the evidence of an ongoing sound change in which SQUARE is shifting towards NEAR, these shape differences were more marked for older than for younger/mid-age speakers. There was no effect of region nor of place of articulation of the preceding consonant; there was a trend for the merger to be more advanced in low frequency words. The study underlines the benefits of FPCA for quantifying the many types of sound changes involving subtle shifts in speech dynamics. In particular, multi-dimensional trajectory shape differences can be quantified without the need for vowel targets nor for determining the influence of the parameters - in this case of the first two formant frequencies - independently of each other.

Development of a GIS platform for Multi-Disciplinary Community Databases to enable Earthquake Resilience and Research
Authors: Noy Ilan , Lambie Emily , Rickard Hayden , Owen Sally
Published: July 2020

This poster describes the initial steps and benefits in the creation of a GIS platform that will enable the hosting, sharing, and linking of spatial, geotechnical, structural, social, and economic datasets. This will enable interested parties to pursue multi-disciplinary research projects that aim to solve what are inherently complex and multi-faceted problems. A span of datasets will be linked to existing multi-storey buildings and integrated into an easy-to-use GIS platform that will have a range of purposes, including: (1) providing the best scientific knowledge spanning numerous disciplines to inform earthquake resilience research; (2) allowing different organisations, including local councils and iwis to make evidence based decisions regarding event-based planning and emergency management and (3) fostering engagement and sharing of data between separate research communities across different disciplines. Urban areas of Dunedin and Palmerston North are currently being used as repeatable case studies to test the feasibility and relationships required to enable the GIS platform’s capabilities. Researchers are being involved in a collaborative, multi-disciplinary, and flexible approach to ensure the GIS platform can benefit a wide array of groups and individuals. Building in flexibility to extend the GIS platform nationwide to construct a national, multi-disciplinary building database using consistent data standards is a primary, long-term goal for the project.

Can Genetic Programming Do Manifold Learning Too?
Authors: Lensen Andrew , Xue Bing , Zhang Mengjie
Published: July 2020

© Springer Nature Switzerland AG 2019. Exploratory data analysis is a fundamental aspect of knowledge discovery that aims to find the main characteristics of a dataset. Dimensionality reduction, such as manifold learning, is often used to reduce the number of features in a dataset to a manageable level for human interpretation. Despite this, most manifold learning techniques do not explain anything about the original features nor the true characteristics of a dataset. In this paper, we propose a genetic programming approach to manifold learning called GP-MaL which evolves functional mappings from a high-dimensional space to a lower dimensional space through the use of interpretable trees. We show that GP-MaL is competitive with existing manifold learning algorithms, while producing models that can be interpreted and re-used on unseen data. A number of promising future directions of research are found in the process.
Generating redundant features with unsupervised multi-tree genetic programming
Authors: Lensen Andrew , Xue Bing , Zhang Mengjie
Published: July 2020

© Springer International Publishing AG, part of Springer Nature 2018. Recently, feature selection has become an increasingly important area of research due to the surge in high-dimensional datasets in all areas of modern life. A plethora of feature selection algorithms have been proposed, but it is difficult to truly analyse the quality of a given algorithm. Ideally, an algorithm would be evaluated by measuring how well it removes known bad features. Acquiring datasets with such features is inherently difficult, and so a common technique is to add synthetic bad features to an existing dataset. While adding noisy features is an easy task, it is very difficult to automatically add complex, redundant features. This work proposes one of the first approaches to generating redundant features, using a novel genetic programming approach. Initial experiments show that our proposed method can automatically create difficult, redundant features which have the potential to be used for creating high-quality feature selection benchmark datasets.
Ways of Knowing, Being, Doing and Becoming: Engaging Indigenous Knowledges in Higher Education
Authors: Mercier Ocean , Leonard Beth
Published: July 2020

For 11 years, virtual coursework between Alaska and Aotearoa has provided a shared space for students to explore some of the most pressing social and environmental challenges at the cultural interface of Indigenous Knowledges. In this session we discuss an annual virtual exchange that engages Māori, Alaskan, Native and non-Indigenous students, including undergraduate and graduate students from different universities, nations, hemispheres and continents. The course is co-taught by two Indigenous scholars - Ocean Mercier, of Māori descent, and Beth Leonard, of Dene’/Athabascan descent, and draws students and their interests into conversation, using online forums, synchronous videoconferencing, and small group discussions. As Indigenous faculty we are engaged interested in a transformative, critical ‘shaping of spaces’ that serves students from marginalized groups. In addition, our ongoing research examines the influence of Indigenous studies in culture-, value- and land-based education as related to the strengthening of identity and belonging for Indigenous students in higher education. University/tertiary classrooms can be reconstructed to connect disparate disciplines, geographically separated people, and different ways of knowing. Our tertiary teaching spaces can properly acknowledge Indigenous histories (as bound to discreet places/spaces), be experimental, a nursery of ideas, and pedagogically revolutionary. Importantly, relationships are at the center of our engagement between Alaska and Aotearoa. We set the stage for a mutually-beneficial interaction. We provide space for different ways of knowing, and producing knowledge to be affirmed and expressed in a multitude of ways. In this way the space becomes a respectful one that honors multiple traditions.

We Need the Open Artefact: Design Science as a Pathway to Open Science in Information Systems Research
Authors: Doyle Cathal , Luczak-Roesch Markus , Mittal A
Published: July 2020

© 2019, Springer Nature Switzerland AG. Design science research (DSR) is facing some significant challenges such as how to make the knowledge and artefacts we create more accessible; exclusion from competitive funding schemes that require open practices; and a potential reproducibility crisis if scholars do not have access to everything needed to repeat past research. To help tackle these challenges we suggest that the community should strongly engage with open science, which has been growing in prominence in other fields in recent years. A review of current DSR literature suggests that researchers have not yet discussed how open science practices can be adopted within the field. Thus, we propose how the concepts of open science, namely open access, open data, open source, and open peer review, can be mapped to a DSR process model. Further, we identify an emerging concept, the open artefact, which provides an opportunity to make artefacts more accessible to practice and scholars. The aim of this paper is to stimulate a discussion amongst researchers about these open science practices in DSR, and whether it is a necessary step forward to keep the pace of the changing academic environment.

Climate Change Adaptation in the Coastal Tourism Hotel Sector: The case of Sihanoukville, Cambodia
Authors: Nhep Tinat , Schott Christian , Sahli Mondher
Published: July 2020

Cambodia is a country, which has seen very rapid tourism development over the last decade, while also being identified as very vulnerable to the impacts of climate change (CC) by several key international agencies. This paper takes the form of a climate change-focused case study of the coastal tourism hotel sector in Cambodia’s Sihanoukville. It is based on semi-structured interviews with hotel managers and field observations. The paper’s aims are sequential and start by initially examining to what extent Sihanoukville’s hotel sector is vulnerable to CC, which is followed by an analysis of the hotel sector’s adaptation. Finally the type and nature of adaption is critically compared and contrasted by star rating and location relative to the seashore. Some interesting findings emerge that highlight paradoxes in the context of the vulnerability- adaptation dynamic. Future research should investigate the barriers and critical success factors (SF) for CC adaptation (CCA), as these factors will provide valuable insights into the vulnerability-adaptation dynamic in Sihanoukville, thereby contributing to the UN’s Sustainable Development Goal (SDG) 13 Climate Action.
A multi-tree genetic programming representation for melanoma detection using local and global features
Authors: Ain Q Ul , Al-Sahaf Harith , Xue Bing , Zhang Mengjie
Published: July 2020

© Springer Nature Switzerland AG 2018. Melanoma is the deadliest type of skin cancer that accounts for nearly 75% of deaths associated with it. However, survival rate is high, if diagnosed at an early stage. This study develops a novel classification approach to melanoma detection using a multi-tree genetic programming (GP) method. Existing approaches have employed various feature extraction methods to extract features from skin cancer images, where these different types of features are used individually for skin cancer image classification. However they remain unable to use all these features together in a meaningful way to achieve performance gains. In this work, Local Binary Pattern is used to extract local information from gray and color images. Moreover, to capture the global information, color variation among the lesion and skin regions, and geometrical border shape features are extracted. Genetic operators such as crossover and mutation are designed accordingly to fit the objectives of our proposed method. The performance of the proposed method is assessed using two skin image datasets and compared with six commonly used classification algorithms as well as the single tree GP method. The results show that the proposed method significantly outperformed all these classification methods. Being interpretable, this method may help dermatologist identify prominent skin image features, specific to a type of skin cancer.
An approach for selecting and using a method of inter-coder reliability in information management research
Authors: Nili A , Tate M , Barros A , Johnstone David
Published: July 2020

© 2020 Elsevier Ltd Qualitative researchers in information management research often need to evaluate inter-coder reliability (ICR) to test the trustworthiness of their content analysis. A suitable method of evaluating ICR enables researchers to rigorously assess the degree of agreement among two or more independent qualitative coders. This allows researchers to identify mistakes in the content analysis before the codes are used in developing and testing a theory or a measurement model and avoid any associated time, effort and financial cost. Different methods have been proposed, but little guidance is available on which approach to evaluating ICR should be used. In this paper, we review and compare leading ICR methods that are suitable for qualitative information management research. We propose an approach for selecting and using an ICR method, supported by an illustrative example. The five steps in our proposed approach include: selecting an ICR method based on its characteristics and requirements of a project; developing a coding scheme; selecting and training independent coders; calculating the ICR coefficient and resolving discrepancies; and reporting the process of evaluating ICR and its results.
A Tool for Modelling Business Behaviour Using Decision Tables

Published: July 2020

© 2019 IEEE. Decision tables have been recently recognised as an effective technique to model business behaviour. The increasing adoption of decision tables in this context requires appropriate end-user support. Although several tools have been developed using decision tables, few have been targeted to business end users. This paper fulfils this gap by proposing a tool supporting end users to capture and model business behaviour. The proposed tool integrates decision tables for capturing actionable knowledge using ontology technology. The tool is validated in two case studies.

Crowdsourcing can be an adopted strategy for researchers where tasks are distributed to internet users to harness different forms of data, which adds to the reliability and validity of the research process. As theory testing is an essential part of the research process, involving activities that most times needs input from different and diverse participants, the need to consider adopting the crowdsourcing strategy for theory testing is paramount. Adopting a design science paradigm to manage this challenge, we design an analytic framework which comprises of important attributes that need to be considered if crowdsourcing is to be used for any of the theory testing activities. The framework which was justified using sample cases gives us an insight into what attributes make such activity crowdsource-able. The value of this artefact lies in its capacity to help researchers utilize crowdsourcing to their advantage.

This paper examines the possibilities of using the crowdsourcing strategy for theory testing. We first analyse the relationships between theory building and theory testing activities. Then, based on a systematic review of 248 papers published in MISQ, we characterise the intents and pattern systems of activities that have been used for theory testing. Finally, we ascertain which activities can be crowdsourced or not and pinpoint a set of pathways supporting partial and total crowdsourcing. The obtained results show that a large number of activities related to data gathering can be crowdsourced, and that a number of intents have viable pathways supporting partial crowdsourcing.
Professing Criminal Law
Authors: Smith Anthony
Published: July 2020

© Cambridge University Press 2013. This celebration of Glanville Williams’ contribution to the world of criminal law scholarship presents an occasion upon which to reflect not only on that contribution, but also upon wider considerations of what professors of the criminal law (the subject broadly conceived) have done and can do in carrying out their professorial duties. The rather limited purpose of this chapter is to alert younger academics, in particular, to the extent to which they become increasingly free to define themselves by what they choose to do as their careers progress. Glanville’s was a career that exemplified many dimensions of what is possible, and he excelled in many of them. A survey of his career also affords an opportunity to draw attention to a corollary, namely, that there are certain activities to which academic criminal lawyers are by and large unable to aspire, and in particular the practice of the discipline that they profess. A principal attraction for those who pursue academic law as a career path is that they are relatively free to make of it what they will. There is no paradigm – we cannot be prescriptive as to what professors of the criminal law should or even might do. Instead, there is a menu of possibilities from which scholars are relatively free to choose, within the boundaries dictated by individual aptitudes and the institutional circumstances in which they find (or to which they steer) themselves as careers develop. As a minimum, the modern university-based academic is expected to engage in research and teaching in about equal measure, with the remainder of her or his time devoted to ‘administration’ or general contribution. Apart from this, there is much more that the academic could do outside the lecture halls and corridors, and Glanville participated in many, perhaps most, of the available options.
Approximate T matrix and optical properties of spheroidal particles to third order with respect to size parameter
Authors: Majić MRA , Pratley L , Schebarchov D , Somerville Walter , Auguié B , Le Ru Eric
Published: July 2020

© 2019 American Physical Society. In electromagnetic scattering, the so-called T matrix encompasses the optical response of a scatterer for any incident excitation and is most commonly defined using the basis of multipolar fields. It can therefore be viewed as a generalization of the concept of polarizability of the scatterer. We calculate here the series expansion of the T matrix for a spheroidal particle in the small-size, long-wavelength limit, up to third lowest order with respect to the size parameter, X, which we will define rigorously for a nonspherical particle. T is calculated from the standard extended boundary condition method with a linear system involving two infinite matrices P and Q, whose matrix elements are integrals on the particle surface. We show that the limiting form of the P and Q matrices, which is different in the special case of spheroid, ensures that this Taylor expansion can be obtained by considering only multipoles of order 3 or less (i.e., dipoles, quadrupoles, and octupoles). This allows us to obtain self-contained expressions for the Taylor expansion of T(X). The lowest order is O(X3) and equivalent to the quasistatic limit or Rayleigh approximation. Expressions to order O(X5) are obtained by Taylor expansion of the integrals in P and Q followed by matrix inversion. We then apply a radiative correction scheme, which makes the resulting expressions valid up to order O(X6). Orientation-averaged extinction, scattering, and absorption cross sections are then derived. All results are compared to the exact T-matrix predictions to confirm the validity of our expressions and assess their range of applicability. For a wavelength of 400 nm, the new approximation remains valid (within 1% error) up to particle dimensions of the order of 100-200 nm depending on the exact parameters (aspect ratio and material). These results provide a relatively simple and computationally friendly alternative to the standard T-matrix method for spheroidal particles smaller than the wavelength, in a size range much larger than for the commonly used Rayleigh approximation.

Published: July 2020

Physical exercise has been suggested to show beneficial effects for various diseases and also for sleep. This study aims to assess the prevalence of sleep problems, and the relationship of physical exercise with sleep health among adult male exercisers. A total of 199 randomly selected athletes (all males) took part in this study. All participants responded to a questionnaire consisted of items related to demographic information that also included sports participation level, and playing experience. Self-reported sleep quality and physical exercise were using PQSI and three items concerning exercise frequency, intensity, and duration. The analysis revealed following main findings: 1) a significant negative correlation between physical exercise and sleep medication, 2) a significantly negative relationship between sports/ exercise participation level and sleep disturbance, 3) an 3.7 average global score of PSQI in total sample, 4) Exercise frequency was negatively correlated with daytime dysfunction whereas exercise intensity was negatively correlated with sleep disturbance and sleep efficiency but positively correlated with daytime dysfunction, 5) and prevalence of poor sleep in 22 % participants. There is some possibility to suggest that exercise may improve sleep health among adult male exercisers. The increased exercise frequency more positive impact to improve sleep but the relationship between exercise intensity and sleep remains inconclusive. existence of sleep problems in athletic population essentially require further attention for reducing the prevalence of poor sleep using other approaches along with continue doing exercise for good sleep.

This is the calculation of the modernized index human development based on the adjective model based on 26 indicators (social, economic and environmental subsystems), as well as using the methods of the main components and the slip matrix. The resultant value is the modernized Human Development Index (MHDІ) of Ukraine.
The architectonics MHDІ of Ukraine in 2007–2017 from the position of sub-indices of the ecological, social and economic subsystems is analyzed.
Consequently, the scientific and methodological approach based on the MHDI change allows us to draw conclusions regarding the effectiveness of the work and public administration bodies in the context of making managerial decisions regarding the satisfaction of the vital interest’s population. MHDI considers the main regulated parameter of the system management in the innovation factors of sustainable development in socially oriented economy. The tendency of steady decline MHDI of Ukraine in 2007–2017 on 53.45 % was confirmed, which confirms inefficient state regulation of crisis situations in Ukraine.
In order to increase the efficiency management of innovative factors by sustainable development of the national economy, from the standpoint of satisfaction vital interest’s population, it is proposed to intensify the use of public debt and savings bonds, market and non-market methods of relief and debt load. This is due to the fact that at the current stage of development in the national economy, public external debt is one of the most significant indicators of the state economy. It is at the same time a criterion for the effectiveness of public financial policy, as well as a threat and opportunity for the Ukrainian economy. In order to optimize its size, various methods, approaches, tools are used. Based on the analysis of world experience, it has been established that the securities market, in particular debt securities, plays a strategic role in regulating this issue. Therefore, it makes sense to recommend government debt bonds and government savings bonds to optimize the amount of external public debt.

For Ukraine the issue of renewable energy development is extremely relevant in view of energy (increase in energy independence), economic (reduction of energy resources import costs), environmental (reduction of environmental pollution) and social (improvement of energy supply, increase in income of the population) problems that can be solved at its expense. Based on the existing potential, if there exist adequate mechanisms of government support for the renewable energy development, Ukraine may increase the share of renewable energy sources in the energy balance up to 25% by 2035, reducing to import a significant share of energy resources. In order to justify the economic feasibility of investing in households’ renewable energy projects until 2029 and to identify the promising trends in this sector development in Ukraine, the authors have assessed the economic efficiency of a project of 10 kW solar power plant construction in a typical Ukrainian household under some conditions. The results have shown that it is expected to observe a gradual outflow of investments from renewable energy sector of households since 2022-2023 due to the decrease in feed-in tariff rates and a corresponding decrease in the profitability of private renewable energy projects with small power capacities. Therefore an alternative powerful state support will be needed to provide the development of renewable energy sector.

It is very important to provide of housing to the population at affordable prices in the developing countries. It should be noted that the concept of “reasonable price” is differently stated in the experience of different countries of the world. The studies show that today about 330 million families in developing and also in developed countries are faced with the problem of obtaining quality housing at affordable prices, and this figure is gradually increasing. Despite the fact that the number of apartments built in the Azerbaijan Republic, which is rapidly developing in the residential real estate market, is quite large, it is impossible to purchase housing for the low-income population, since the prices are very high. It also plays a role the high price of land in cities and low mortgage lending. In housing construction investments the proportion invested in land purchases is very high. Taking into account the above, the Strategic Road Map was developed and adopted to increase the affordability of housing in the Republic of Azerbaijan. To achieve the nominated goals established the State Agency for Housing Construction (abbreviation in Azeri-MIDA) and started construction of two large residential complexes. This article touches upon the task of providing the population of Azerbaijan with housing at affordable prices.
