The article deals with the problem of assessing the socio-economic efficiency of investment in the expansion of University housing infrastructure. Evaluating the effectiveness of investment design solutions is the main approach to determining the return on investment of financial resources in expanding the Fund of student dormitories, in which both investors and all participants in the implementation of investment projects

While evaluating and selecting investment projects, modern companies are confronted with the problem of setting priorities between profitability and riskiness of these projects. Choice of a project on the basis of its profitability significantly increases risks of financial and economic activities and decreases the certainty of achieving the planned financial result. On the other hand, attempts to decrease investment projects risks may not allow one to achieve the desired profitability level. Therefore, it is vital to develop integrated multi-criteria indicators for this purpose. This article is the result of the authors’ development of an integral indicator for evaluating investment project efficiency and risks. The developed integral indicator has a matrix form. To compile the integral indicator, three groups of criteria are used: quantitative efficiency criteria, qualitative efficiency criteria and risk evaluation criteria. We propose to divide the qualitative and quantitative criteria into: 1) those defining the commercial (economic) efficiency of projects, 2) those defining their budgetary efficiency; 3) those defining their social efficiency. According to the authors, the list of criteria that define associated risks should include macroeconomic indicators and industry affiliation indicators that provide a comprehensive evaluation of the external economic situation on the corresponding market. While evaluating efficiency and riskiness of the given projects, the integral indicator developed by the authors is converted from matrix form into a quantitative indicator that is easy to interpret. The authors propose to use principal component analysis and heuristic methods (including ranking method and hierarchy analysis method) for this purpose. The results of this research can be used by companies to select investment projects.

Aim . The presented study aims to formulate the methodological basis of a market mechanism for ensuring the efficiency of investment and construction projects in the context of negligible transaction costs. Tasks . The authors analyze the effect of the relationship between the subjects of an investment and construction project on its efficiency; examine the major groups of fundamental economic mechanisms for enabling integration cooperation between economic entities; describe the IPD approach as the methodological basis of a market mechanism for ensuring the efficiency of investment and construction projects; define the principles of formation of local and global maximum economic effects of investments at the stage of an investment and construction project; formulate the methodological foundations of an economic IPD partnership, which is viewed as a market mechanism for maximizing the integral effect of an investment and construction project. Methods . This study uses general scientific methods of cognition and the institutional approach, which considers the market, organizational, and government groups as the fundamental economic mechanisms for enabling integration cooperation between economic entities, to develop the economic fundamentals of the IPD approach as a methodological basis of a market mechanism for ensuring the efficiency of investment and construction projects. Results . During the implementation of investment and construction projects, the so-called mutual effects of independent entities arise when changes in the cost and/or duration of one stage of the project affect the quality of the results at another stage. The need to develop mechanisms for ensuring the integral efficiency of investment and construction projects by compensating for efficiency losses at each stage is substantiated. In the case of negligible transaction costs, the best such mechanism would be to establish voluntary agreements between the parties based on a market mechanism. In investment and construction management, IPD contracts serve as the instrument of such agreements. The authors develop a methodological basis for an economic IPD partnership by differentiating the subjects included in the IPD contract in correlation with their costs and results within the investment and construction process and by establishing the conditions for remuneration payments and internalization of "internal" externalities by types of subjects in the IPD project. Conclusions . Economic interaction modeled according to the presented methodology is meant to ensure a cognitive IPD partnership combining the knowledge, competencies, and interests of different subjects, experts and specialists, which in turn serves as one of the mechanisms for maximizing the integral effect of an investment and construction project. Having a common digital information space for the project is a modern prerequisite for a successful IPD partnership based on the presented model of economic interaction between subjects.

The article is devoted to the issues of evaluating the efficiency of investment projects, taking into account the justified and objective choice of the discount rate, which significantly affects the accuracy of the indicators of the economic efficiency of the evaluated investment project. In the conditions of an acute shortage of investment resources, the desire to increase the accuracy of the predictive assessment of the effectiveness of investment projects necessitates the search for new scientific and methodological approaches to the justified choice of the discount rate. In each specific situation, this choice depends on a large number of different factors, which are conditionally divided into two groups - internal and external. Unfortunately, in investment projects developed by Ukrainian enterprises, insufficient attention is paid to justifying the discount rate. The article provides an analysis of the main methods of determining the value of the discount rate when evaluating investment projects and scientific and methodological approaches to the selection of the discount rate in order to increase the objectivity of the predictive assessment of the feasibility of implementing an investment project. The essence of the advantages and disadvantages of such "traditional" methods of determining the discount rate of investment projects, such as the SARM model, the cumulative construction model, and the WASS model, are revealed. The effect of the intensity of exogenous factors in the form of the cost of credit resources, tax rates, inflation rates on the result of the assessment of the efficiency of the investment project has been specified. The main problems of justifying the economic efficiency of investment projects in the post-war recovery of the national economy are formulated. The author's rationale for the cumulative premium to the discount rate is given, due to the risk of speculative growth in the cost of construction caused by excess demand for construction work. The indicator of the expected duration of the portfolio of all orders of the construction enterprise, expressed in months, is proposed for use. On the basis of a cluster analysis of retrospective data, the linguistic terms of this meaning "deficit of orders", "partial..." and "sufficient security of the medium-term portfolio of orders" and their corresponding Gaussian membership functions are substantiated. An artificial intelligence system has been developed for forecasting the most likely percentage of speculative overestimation of the cost of construction works performed by the contractor, and the feasibility of using the output of this system as a cumulative premium to the discount rate has been proven.

In the article, the authors turn to the consideration of the issue of increasing the efficiency of investment projects of industrial parks at all stages. The authors of the article point out the importance of localization of foreign production on the territory of the Russian Federation. They point out that the main thing is to audit the materials of the basic engineering of foreign equipment manufacturers. In addition, the development of a task for the design of industrial parks based on own audit of technological processes will save the terms of the project and exclude the risk of stopping production. At the stage of project preparation, an implementation plan is developed that makes it possible to efficiently work with the content, terms of implementation throughout the project. The authors describe the practice of using tools to improve the efficiency of the investment project at all stages. They also, propose tools that enable developing effective conditions for the implementation of industrial parks because of the development of effective public-private partnership projects. In recent years, significant efforts have been made to create and develop a national innovation system. Industrial parks fulfill the most important function of the conducting infrastructure, creating conditions for a sustainable growth of the innovative potential of the regions and reducing the costs of small and medium-sized innovative companies. The use of public-private partnerships is rational in the implementation of projects with a long payback period and a large amount of investment. These projects include industrial park projects, within which an infrastructure is created to develop industrial production. As a result of the implementation of these projects: residents of the industrial park get the opportunity to purchase engineering-prepared land and use additional services; The industrial park increases investment attractiveness and competitiveness; and is also an instrument for solving social problems; The industrial park promotes the development of innovative and knowledge-intensive industrial production.

Innovation projects include: the purchase of housing and durable goods (for individuals); the purchase of equipment; expenses for scientific research and development work; advertising expenses and a number of other expenses; construction of roads and other significant objects of common national purpose. In domestic practice, there is a different classification, including one similar to the one given above. A classification based on the allocation of features of investment projects is also used: the amount of investment (significant, medium, small); by the type of possible profits (reducing costs; increasing profits, ensuring access to international markets, ensuring social efficiency; reducing risks in production and sales); by the type of relationship (alternative, replacing, etc.); by the attitude to risk (risky and risk-free). In all industries and at different levels (decision-making, etc.) there are a large number of different opportunities that are financed from limited sources and financial resources, so it is necessary to optimize investment decisions. The theory of assessing the economic efficiency of investment projects is aimed at obtaining answers to 3 main questions: which specific investment projects should the firm adopt; what is the total volume of capital investments the firm should make; from what sources can the firm's investment portfolio be financed. The answers to these questions are interconnected. At the same time, the problem does not boil down to a simple decision on which direction to finance. Since the volume of borrowing and the size of the share issue are under the supervision of the firm, the decision on the choice of an investment project and a source of financing must be made simultaneously. At the same time, economic growth, over the past 15 years abroad, technical progress has led to the expansion of investment opportunities even for firms with small own funds.

New qualitative and quantitative technical criteria for determining the minimum miscibility pressures (MMPs) with the rising-bubble apparatus (RBA)

In order to prevent the formation of a gap between the quality and quantity in Iranian scientific publications, this study makes an effort to analyze Iranian scientific publications indexed on the ISI Web of Science database using quantitative and qualitative scientometrics criteria over a ten year period. As a first step, all Iranian institutes were divided into three categories; universities, research institutes and other organizations. Then they were compared according to quantitative and qualitative criteria. Second, the correlation between the quality and quantity of the publications was measured. The research findings indicated that, according to qualitative criteria (citation, citation impact and percentage of cited documents) there are no meaningful differences among the three groups, while regarding quantitative criterion(number of papers), universities rank higher than the other two groups. The results also indicated that there is a positive and meaningful correlation among qualitative and quantitative criteria in the scholarly scientific publications conducted by Iranian organizations. In other words, in Iranian organizations the quality of publications increases as their quantity increases. The comparison of magnitude of correlation between these two criteria in the three categories reveals the fact that the correlation between number of papers and citations criterion in research institutes is stronger than the other two groups.

Introduction. Improving the quality of medical services and raising the effectiveness of the operation of the subjects of the medical system of Ukraine requires intensifying innovation, which needs significant investments. So, the application of qualitative methods for analyzing the efficiency of such projects is of great importance.Problem Statement. Scholarly research and methodological framework and practical recommendations deal with the identification of problem areas and aspects of the implementation of innovation and investment projects at healthcare institutions in Ukraine.Purpose. The purpose is to comprehensively analyze and to identify the problematic aspects of the implementation of innovation and investment projects by healthcare institutions and to determine the measures to address them as well as to increase the effectiveness of the innovation. Material and Methods. In the course of the study, the method of economic and mathematical modeling has been used to perform a composite analysis (using the weighted average method) of the effectiveness of the implementation of innovation and investment projects by the example of healthcare institutions.Results. It has been established that the efficiency of the implementation of innovation and investment projects at healthcare institutions of Ukraine is satisfactory, but such components as the financial and economic sustainability of the project and the quality of intellectual and personnel support, especially the structure of investments and their profitability, staff turnover and the level of professional qualification of medical personnel remain problematic. Financial and economic stability and investment andmarketing development remain the most problematic components of the efficiency.Conclusions. One of the key signs of the efficiency of investment and innovation projects in medicine is their systematic manner that involves a combination of measures to activate and develop investment and innovation in the organizational and institutional (1), the economic (2), the product and service (3), the social and psychological (4) components.

Quantitative and Qualitative Ultrasound Evaluation for the Diagnosis of an Anterosuperior Acetabular Labral Tear.

Introduction Insomnia is diagnosed based on subjective difficulty falling asleep, staying asleep, and early morning awakenings. Evidence of objective EEG abnormalities is mixed, in part due to small sample sizes and variable definitions of insomnia. This study aimed to explore these issues by comparing the insomnia case group and the control group on sleep physiology objectively measured depending on separate qualitative and quantitative self-reported insomnia symptoms. Methods Analyses are based on questionnaires and PSG data from the Sleep Apnea Global Interdisciplinary Consortium (SAGIC). Two distinct insomnia case groups were defined. A qualitative insomnia case was defined as self-reported difficulty falling or staying asleep at least 3 nights/week for more than 3 months and moderate or greater impairment in daytime function due to poor sleep (n=350, 58% female; 48.47±14.38 years). The quantitative case definition required average self-reported sleep latency or wakefulness after sleep onset >30 minutes combined with the frequency and impairment criteria. (n=196, 62% female; 48.77±13.74 years). We also defined control groups without insomnia. Participants were excluded if they had sleep apnea (apnea-hypopnea index [AHI] > 5 events/hour) or were shift workers. Multivariate analysis of variance (MANOVA) models, adjusted for age and sex, were separately conducted to compare the insomnia and control groups. The focus was on traditional sleep architecture variables, EEG power within specific frequency bands, and odds ratio product (ORP, representing sleep depth) metrics. Results The MANOVA analysis indicated significant group differences, with post-hoc tests identifying key variables responsible for these distinctions. In qualitative criteria, sleep onset latency, sigma, beta1, and beta2 in EEG1 and EEG2, along with REM and NREM ORP, were significant contributors to the observed differences. In quantitative criteria, besides the same result in qualitative criteria, REM stage and alpha in EEG1 and EEG2 played significant roles. Effect sizes were consistent across both qualitative and quantitative criteria. Conclusion While the analyses depending on qualitative and quantitative criteria did not have different effect sizes, some variables contributed to the group differences. As such, the results of this study support the idea that qualitative and quantitative criteria measure the same dimensions for physiological differences related to insomnia. Support (if any)

The paper defines the basic theoretical and modern methodological approaches to the formation and evaluation of the feasibility of corporative investment projects. These are formed by the organizational structure of investment projects support on the basis of the functional distribution. The efficiency valuation mechanism of the corporative investment project is developed. The model of multi-factor efficiency valuation of corporative investment projects is developed and functionally filled. It is proposed an algorithm for grouping corporative investment projects by efficiency criterion. The analysis of the existing indicators of investment efficiency showed the absence of a valuation indicator the innovative efficiency of investment projects. There are formulated the author’s interpretation of this concept and proposed three-component indicator, the risk and inflation components of which determine what part of the innovative effect of an investment project can be lost as a result of the manifestation, respectively, of risk factors and inflation. It was developed a model of investment project management “investments-risk”, based on the simultaneous formation of a calendar plan and technological budget, as well as determining the probability of occurrence of risk events, measures on the actions for the common goals of investment projects and the development of actions to respond to risks with the use of structural decomposition of works as a result of interrelated calculation of terms and value of investment projects. It was developed a model of investment project management “investments-risk”, based on the simultaneous formation of a calendar plan and technological budget, as well as determining the probability of occurrence of risk events, measures on the actions for the common goals of investment projects. The mechanism of efficiency valuation of investment projects can get a boost in the development by introducing indicators of social and environmental efficiency of the investment project and on this basis determining the social significance, which will improve the quality and objectivity of the general justification of the investment project and will allow to systematize the sequence of valuation.

Purpose This study aims to examine the relationship between supportive design (SD) and residential mobility of students with disabilities (SWD) in off-campus student hostels in Ghana. Design/methodology/approach Quantitative research techniques were adopted. A sample of 243 SWD living in 190 University Student Housing were selected. Based on the SD indicators, the partial least square structural equation model was used to explore its effects on residential mobility in SWD living in university housing. Findings Findings indicate that a sense of control and positive distraction significantly influence residential mobility to a greater extent than social support design. While the sense of control emerged as a primary predictor of residential mobility, no direct relationships were observed between the sense of control, positive distraction and social support. Although social support did not exhibit significant direct effects, its potential relevance to residential mobility cannot be dismissed. Practical implications The enhancement and compliance of a sense of control and positive distraction SD in the common areas in student housing will reduce SWD residential mobility and increase investors’ profitability. Positive social support designs are critical to predicting percentage change in residential mobility in off-campus student housing in Ghana. Originality/value SD is a theory largely used in health-care buildings. The observation of no relationship between a sense of control and positive distraction, and social support aspects of SD in university housing in this study significantly differs from the inverse relationship that exists between SD in hospitals, especially in the developing world, is a theoretical contribution.

The article summarizes scientific discussions on the use of public-private partnership in the health sector and concludes that it is relevant as a tool for sustainable development of the country, regions and individual industries. The structural elements of public-private partnership have been identified. Based on the systematization of literary sources on approaches to the definition of public-private partnership, it was found that the content of the category "public-private partnership" is revealed through the complementarity of the project and institutional approaches, as well as in aspects of strategic development and stylistic reception in a broad sense, as a result of which the author's interpretation of the category public-private partnership in the medical field. The types of public-private partnerships as a tool for sustainable development of the country and its regions are systematized and the feasibility of integrating various projects is substantiated. The main features of public-private partnership in the medical field are revealed, revealing the specifics of partnership between the state and the private sector as an economic category. Key words: public-private partnership, private sector, medical sphere, healthcare, sustainable development. It is proved that the use of the term public-private partnership in scientific and practical activities is associated with the introduction of a new economic form of interaction between the state and the private sector for effective attraction and use of financial resources and organizational opportunities of business in limited investment resources. The author explored the variety of forms and areas of partnership between the state and business, which makes it a universal tool for solving government problems in priority areas of the economy and increasing the country's competitiveness, ensuring sustainable national and regional growth and sustainable economic relations.

Smart lighting is emerging in student housing across Africa. This study assesses the drivers and satisfaction of smart lighting in university housing in Southern Ghana. The study used an embedded research method, including a survey of 334 student residents and interviews with 10 housing managers across five purpose-built student housing facilities at five selected public universities in Southern Ghana. The Relative Importance Index and thematic analysis were used as data analytical techniques. The findings reveal that accommodation needs primarily drove the adoption of smart lighting in student housing. The satisfaction levels of smart lighting were limited to lighting controls in lavatories, bedrooms, study areas, the kitchen, and common areas. However, dissatisfaction with lighting was associated with adjusting to the minimum light intensity and controlling artificial lighting. Technically, the limited influence of facilities management factors on smart lighting adoption poses a significant risk to energy sustainability if left unaddressed. Interviews reveal that students' lack of knowledge impacts their satisfaction with and usage of smart lighting systems. At a minimum, student housing managers and students would need education on smart lighting.
