Thermal request optimization of a smart district heating system

This paper proposes a solution approach to manage the heating plans of tenants served by a district heating plant located in Sweden. To do that, the daily temperature request of each household in the associated pilot region is obtained, and the daily temperature profile of each household is optimized with the help of the proposed decision support system and smart valves. The hot water inflow rates of radiators are remotely controlled via smart valves at each flat to minimize the total energy consumption, carbon emission and cost associated with the energy consumption of the district heating plant. We aim to shave the peak demands while fully satisfying the temperature requests of households without violating their thermal comfort. Peak demand shaving is achieved by generating preheating schedules via mathematical optimization and using the thermal storage potential of the insulated flats. The resulting mathematical optimization model presents significant computational challenges that cannot be efficiently solved using optimization solvers within a reasonable time limit. To this end, we develop three genetic algorithm approaches that are computationally scalable for realistically-sized instances and verified to yield near-optimal solutions for the test instances. Extensive numerical analyses show the effectiveness of the proposed approach and the genetic algorithm since we yield significant carbon emission reduction and cost savings compared with the method that the experts of the utility company propose.

P029 Successful treatment of Rapidly progressive MDA-5 with dual combination therapy as a bridge to lung transplantation

Abstract Background/Aims Anti-melanoma differentiation-associated gene 5 (MDA5) is known to be associated with rapidly progressive interstitial lung disease (RP-ILD) and is fatal in most cases. The aim of this case report is to highlight the importance of early detection and aggressive treatment in improving the survival of these patients. Methods A 48-year-old Caucasian man, ex-smoker with 20 pack year history with well-controlled asthma, GORD, hiatus hernia and chondrocalcinosis in right knee on hydroxychloroquine was noted to have finger clubbing and decreased air entry at the right lung base on routine follow up. He worked in print finishing for 18 years. Results Investigations: CXR-increased interstitial shadowing. CT chest-extensive fibrosis NSIP pattern with honey combing, traction bronchiectasis throughout both lung fields and ground glass changes at the lower lobes. FVC 2.99 (63% predicted), FEV1 2.82 (73% predicted), FEV1/FVC ratio 0.95%, TLCO 2.75 (25% predicted), KCO 0.70 (46% predicted). CK- 76, Myositis blot- MDA 5 +ve, c ANCA +ve, PR3&MPO -ve and ANA -ve. CRP 70. Bronchoscopy-normal. He received IV methyl prednisolone 1 gm x 3 followed by prednisolone 60 mg daily and tapering dose along with Cyclophosphamide IVI 1 gm x 6 cycles. Long term home oxygen was prescribed. As he did not improve on initial immunosuppressive treatment, Rituximab IVI 1 gm x 2 was administered within two months of initial therapy. He was referred for lung transplant. As maintenance, he was on mycophenolate 1.5 gm BD, prednisolone 10 mg OD, Co-trimoxazole 960 mg x 3 days per week and rituximab 1 gm at six months and 12 months. He had bilateral lung transplant in Cambridge after two years from the diagnosis. Unfortunately, he developed organizing pneumonia, primary graft dysfunction requiring a brief ITU admission and tracheostomy soon after the transplant. His current medications include Prednisolone 5mg, Mycophenolate 2g Tacrolimus 3mg mane, 2mg nocte, Azithromycin 250mg three times weekly and Septrin 480mg od. He is now managing well, cycling 10-15 miles daily. He no longer requires ambulatory oxygen. His most recent FEV1 4.1L, FVC4.9L and resting saturation 97%. Dual combination aggressive immunosuppressive therapy led to significant disease control in this patient, enabling him to be enlisted for and finally to receive a double lung transplant within a reasonable time limit. It has been reported that patients with MDA 5 ILD have a 1-year survival of 67.5% and a 3-year survival of 46.7%. Conclusion Key Learning Points: Patients with MDA5-ILD have significantly high mortality rate but early diagnosis and optimal treatment combination can lead to favourable outcomes. These patients should be monitored for opportunistic infections. Patient commitment is important. Our patient stopped smoking, reduced weight to improve fitness to optimise the transplant success.

E005 Immunoglobulins review prior to rituximab infusion: implications and how we can improve our service

Abstract Background/Aims Rituximab (RTX), used in the treatment of autoimmune and lymphoproliferative diseases, depletes B-cells through anti-CD20. The resulting hypogammaglobulinemia increases susceptibility to recurrent or severe infections, however the absence of a protocolised approach to measuring serum immunoglobulin levels prior to, or between, RTX infusions in our infusion unit has led to cancelled treatments, and even delivery of treatments without a timely record of immunoglobulin levels. British Society for Rheumatology guidelines recommend checking immunoglobulin levels prior to treatment, then four to six months after infusions and before any future cycles of treatment. Our aim was to optimise monitoring standards of immunoglobulin levels in patients receiving RTX infusions, thereby minimising avoidable harm and unnecessary treatment cancellations. Methods Data was collected retrospectively using electronic patient records. The analysis included sixty patients with rheumatological conditions scheduled for RTX infusions during a three-month period. Results Treatment was appropriately withheld in six patients without up-to-date immunoglobulin levels, and in one patient with active infection. However, RTX was given in 28% (17 out of 60) of patients without up-to-date immunoglobulin levels; the mean duration of time between the current cycle of RTX treatment and most up-to-date prior immunoglobulin result being 179 days (median 109 days). Of note, this exceeded 200 days for 4 of these 17 patients (24%), and an absence of pre-RTX immunoglobulin levels was observed in a further 3 of these 17 patients (18%). Although no adverse events have occurred, this represents a compromise in patient safety. Whilst there is no definitive guidance on the reasonable maximum time limit between a RTX infusion and the most up-to-date immunoglobulin levels, a departmental consensus of one month was agreed upon through discussion and literature reviews. Robust measures have been taken, using a multi-disciplinary and multi-step approach, to achieve this:1. Patient list generated one week in advance for the clinical team to review pre-screening tests, including immunoglobulins. Any missing tests can be requested in advance of the infusion date.2. Pharmacy update of their checklist to include reviewing immunoglobulins results prior to dispensing Rituximab; escalating to the clinical team if missing or abnormal result.3. If the above measures have failed, a final safety net has been agreed by the multi-disciplinary team that bloods are taken and urgently processed in the laboratory, with RTX conditionally screened by pharmacy, to reduce treatment delay from appointment cancellation. Conclusion Next steps will be to develop this into a first cycle of quality improvement. This will involve measuring changes from comparing data points prior to and after implementation of the above changes. Furthermore, rates of post-RTX infections or complications of immunodeficiency will be measured before and after the interventions to determine the impact on patient safety and minimise avoidable harm and unnecessary treatment cancellations.

Developing an initial set of quality indicators for chiropractic care: a scoping review

BackgroundQuality indicators are standardized, evidence-based measures of health care quality. Currently, there is no basic set of quality indicators for chiropractic care published in peer-reviewed literature. The goal of this research is to develop a preliminary set of quality indicators, measurable with administrative data.MethodsWe conducted a scoping review searching PubMed/MEDLINE, CINAHL, and Index to Chiropractic Literature databases. Eligible articles were published after 2011, in English, developing/reporting best practices and clinical guidelines specifically developed for, or directly applicable to, chiropractic care. Eligible non-peer-reviewed sources such as quality measures published by the Centers for Medicare and Medicaid Services and the Royal College of Chiropractors quality standards were also included. Following a stepwise eligibility determination process, data abstraction identified specific statements from included sources that can conceivably be measured with administrative data. Once identified, statements were transformed into potential indicators by: 1) Generating a brief title and description; 2) Documenting a source; 3) Developing a metric; and 4) Assigning a Donabedian category (structure, process, outcome). Draft indicators then traversed a 5-step assessment: 1) Describes a narrowly defined structure, process, or outcome; 2) Quantitative data can conceivably be available; 3) Performance is achievable; 4) Metric is relevant; 5) Data are obtainable within reasonable time limits. Indicators meeting all criteria were included in the final set.ResultsLiterature searching revealed 2562 articles. After removing duplicates and conducting eligibility determination, 18 remained. Most were clinical guidelines (n = 10) and best practice recommendations (n = 6), with 1 consensus and 1 clinical standards development study. Data abstraction and transformation produced 204 draft quality indicators. Of those, 57 did not meet 1 or more assessment criteria. After removing duplicates, 70 distinct indicators remained. Most indicators matched the Donabedian category of process (n = 35), with 31 structure and 4 outcome indicators. No sources were identified to support indicator development from patient perspectives.ConclusionsThis article proposes a preliminary set of 70 quality indicators for chiropractic care, theoretically measurable with administrative data and largely obtained from electronic health records. Future research should assess feasibility, achieve stakeholder consensus, develop additional indicators including those considering patient perspectives, and study relationships with clinical outcomes.Trial registrationOpen Science Framework, https://osf.io/t7kgm

Разумный срок судебного разбирательства по уголовному делу

The analysis of the concept of a reasonable timeframe for court proceedings is a pressing issue in the current stage of the development of criminal procedure in Russia. Several international mechanisms for protecting individual rights in the sphere of criminal proceedings, including those for contesting reasonable timeframes, have been lost. The study employed general and specific scientific methods, such as dialectical, axiological, and synergetic approaches, as well as the theory of social action and modeling. Moreover, the application of methods of analysis and synthesis of information, comparative legal analysis, and formal legal approaches allowed the author to reach reliable conclusions. The research established that failure to adhere to reasonable timeframes for judicial decision-making violates the rights of individuals involved in criminal proceedings. Ensuring the protection of individuals’ rights and legitimate interests is only possible when reasonable time limits in criminal procedure are observed. Based on the provisions related to compensation for violations of the principle of reasonable timeframes during court proceedings, a conclusion was drawn regarding the essence of these provisions, which allows for an evaluation of the criteria of reasonableness outlined by the legislator and the identification of methods for their assessment.

Nested column generation for split pickup vehicle routing problem with time windows and time-dependent demand

This study attempts to solve a split pickup vehicle routing problem with time windows and time-dependent demand. This is a vehicle routing problem in which demand is generated at different constant rates for different customers, and vehicles are allowed to pick up demand during the demand generation process. In this problem, the pickup time determines the quantity of demand that can be picked up, and a partial pickup is permitted during a single visit. The problem is formulated into a mixed-integer nonlinear programming model, and a sequence-extended network is designed to represent the relationship between multiple pickups. Because of the interdependences of time, load, and cost in the pricing subproblem, the classic labelling algorithm with weak dominance rules is ineffective, therefore, a nested column generation-based branch-and-price-and-cut algorithm is proposed to tackle the problem. The nested structure allows these trade-offs to be resolved in a lower-level column generation, and it can be applied to other interdependent routing problems. The computational results show that the proposed algorithm is effective in obtaining optimal solutions for small- and medium-scale instances within a reasonable time limit.

A new solution approach for the twin yard crane scheduling problem in automated container terminals

The Twin-Automated Stacking Crane (Twin-ASC) system is a special configuration of Yard Crane (YC) that is common in most of the Automated Container Terminals (ACTs) used for stacking and retrieving containers on the yard side of a Container Terminal (CT). The usual objective when scheduling the Twin-ASC to perform a given set of transport jobs is the minimization of the schedule length (makespan). The problem is NP-hard, which means that problem of realistic size cannot be solved within a reasonable time limit by default solvers or conventional methods, necessitating the use of an efficient algorithm. Thus, this work proposes a novel algorithm based on the modified Johnson Algorithm (JA) to a formulated Mixed Integer Programming (MIP) model for solving the Twin-ASC scheduling problem to minimize the makespan of the schedule. Differ from the existing heuristics, the proposed algorithm has the flexibility of varying the handshake area, and the system utilization can be investigated. The handshake area is a temporary storage location in the Twin-ASC system where an ASC can leave a job for the other to complete since the crossing of the cranes is not possible, and it greatly affects the makespan of completing the given set of jobs. An extensive computational study was carried out and results were compared with (two) existing heuristics to evaluate the effectiveness of the proposed solution approach.

Reasonable Time - Is It a Factor of Efficiency in Criminal Proceedings?

The principle of reasonable time, included in Art. 6.1. of the Criminal Procedure Code of the Russian Federation in 2010, is viewed in Russian criminal procedure law theory as a considerable contribution to the development of human rights guarantees in the sphere of criminal court proceedings. The legal nature of this principle, stemming from Art. 6 of the European Convention, which includes the concept «reasonable terms» in the general formula of each persons right to a fair trial, definitely reflects the expectations of all parties involved in criminal procedure relations. However, the introduction of this principle did not lead to any meaningful positive changes in the practice of law enforcement: violations of criminal procedures time limits remain an intractable problem. This problem, caused by the absence of any commonly recognized understanding of reasonable time limits for procedural activities, resulted in risks whose legal consequences are unacceptable for the society, the victims, the accused or the convicted, and create a negative attitude to the court system in general. The authors express their opinions regarding the problem of observing time limits, the understanding of reasonableness in law, and the legal regulation of the observance of procedural limits. They also present suggestions on improving the legal regulation of time limit observance in criminal proceedings. If such a principle of national court proceedings as reasonable time limit (part of the system of criminal proceedings) is violated, it leads to additional problems deteriorating the proceedings for criminal cases. The understanding of reasonable time is connected with the legal conscience of the law enforcer that, on the one hand, is always individual and, on the other - does not necessarily coincide with the opinion of scholars on this issue. The variety of actions and persons who carry them out, especially at the pre-trial stages, makes it necessary to develop a fixed understanding of a reasonable time limit, whose observance should not be equaled with the observance of procedural actions which, due to various circumstances, like the weather or some circumstances of subjective nature, could contribute to the violation of procedural time limits set out by law. Correspondingly, the improvement of the legal regulation of the observance of time limits for procedural actions as an important part of a fair criminal trial presupposes taking into consideration the whole range of relations emerging in the enforcement of criminal procedure legislation.

Min-Sup-Min Robust Combinatorial Optimization with Few Recourse Solutions

In this paper, we consider a variant of adaptive robust combinatorial optimization problems where the decision maker can prepare K solutions and choose the best among them upon knowledge of the true data realizations. We suppose that the uncertainty may affect the objective and the constraints through functions that are not necessarily linear. We propose a new exact algorithm for solving these problems when the feasible set of the nominal optimization problem does not contain too many good solutions. Our algorithm enumerates these good solutions, generates dynamically a set of scenarios from the uncertainty set, and assigns the solutions to the generated scenarios using a vertex p-center formulation, solved by a binary search algorithm. Our numerical results on adaptive shortest path and knapsack with conflicts problems show that our algorithm compares favorably with the methods proposed in the literature. We additionally propose a heuristic extension of our method to handle problems where it is prohibitive to enumerate all good solutions. This heuristic is shown to provide good solutions within a reasonable solution time limit on the adaptive knapsack with conflicts problem. Finally, we illustrate how our approach handles nonlinear functions on an all-or-nothing subset problem taken from the literature. Summary of Contribution: Our paper describes a new exact algorithm for solving adaptive robust combinatorial optimization problems when the feasible set of the nominal optimization problems does not contain too many good solutions. Its development relies on a progressive relaxation of the problem augmented with a row-and-column generation technique. Its efficient execution requires a reformulation of this progressive relaxation, coupled with dominance rules and a binary search algorithm. The proposed algorithm is amenable to exploiting the special structures of the problems considered as illustrated with various applications throughout the paper. A practical view is provided by the proposition of a heuristic variant. Our computational experiments show that our proposed exact solution method outperforms the existing methodologies and therefore pushes the computational envelope for the class of problems considered.

Inspection reports reflect daily operations of Food Service Establishments (FSE) with indications on levels of compliance with food safety standards and regulations, thus, making them central to the enforcement processes in food safety control systems. While compliance with food safety standards and regulations in FSEs is often viewed by the number of non-compliances or inspection violations cited during inspections, non-compliance with inspection recommendations may be an indication of continued non-compliance to the food safety standards. Using a cross-sectional study design, we assess the factors that influence compliance of FSE with inspection recommendations in Mansa Municipality, Zambia. This involved extraction of inspection process details from inspection reports for FSEs inspected was analyzed, followed by the administration of a questionnaire to FSE managers or owners on management and socio-economic factors. The data collected was subjected to both descriptive and inferential analysis. Importantly, the study results revealed that administrative enforcement, follow-up inspections, and reasonable time limits to make corrections are necessary factors to be considered in inspection processes for food establishments to comply with inspection recommendations. FSE owners compared to assigned managers exert more influence on the establishment’s compliance to inspection recommendations when actively involved in the daily operations. Well-operated inspecting institutions and FSE owners play key roles in facilitating FSEs' compliance with inspection recommendations as this ultimately facilitates compliance with food safety standards.   Key words: Compliance, Inspection recommendations, Inspection violation, Food Service Establishment, Foodborne illness.

An algorithm selection approach for the flexible job shop scheduling problem: Choosing constraint programming solvers through machine learning

Constraint programming solvers are known to perform remarkably well for most scheduling problems. However, when comparing the performance of different available solvers, there is usually no clear winner over all relevant problem instances. This gives rise to the question of how to select a promising solver when knowing the concrete instance to be solved. In this article, we aim to provide first insights into this question for the flexible job shop scheduling problem. We investigate relative performance differences among five constraint programming solvers on problem instances taken from the literature as well as randomly generated problem instances. These solvers include commercial and non-commercial software and represent the state-of-the-art as identified in the relevant literature. We find that two solvers, the IBM ILOG CPLEX CP Optimizer and Google’s OR-Tools, outperform alternative solvers. These two solvers show complementary strengths regarding their ability to determine provably optimal solutions within practically reasonable time limits and their ability to quickly determine high quality feasible solutions across different test instances. Hence, we leverage the resulting performance complementarity by proposing algorithm selection approaches that predict the best solver for a given problem instance based on instance features or parameters. The approaches are based on two machine learning techniques, decision trees and deep neural networks, in various variants. In a computational study, we analyze the performance of the resulting algorithm selection models and show that our approaches outperform the use of a single solver and should thus be considered as a relevant tool by decision makers in practice.

REASONABLE TIME LIMIT FOR OBTAINING AN EXPERT OPINION AT THE STAGE OF INITIATING CRIMINAL PROCEEDINGS

The purpose of the study is to determine the reasonableness of the time limit for obtaining an expert opinion in the course of verifying a crime report at the stage of initiating criminal proceedings. The study is based on the provisions of the current legislation on criminal procedure as well as on the by-laws governing the appointment and conduct of forensic examinations. Moreover, the findings of the article are based on investigative and judicial practice. The study employs a variety of scientific methods: information analysis and synthesis, empirical-critical, comparative-legal, systemic. These methods make it possible to identify the status of the problem of determining the reasonable time limit for conducting forensic examinations and ways to overcome difficulties arising in investigative practice. The result of the study is the interpretation of the norm of Art. 144 of the Code of Criminal Procedure of the Russian Federation and the consequent proposal to establish a system of by-laws in which the question of time limits would be decided according to the type of relevant forensic examination.

The right to a justice court: implementation of the practice of the European Court of human rights in the Ukrainian judiciary

The purpose of this study is to reveal the content of the right to a fair trial and the state of its provision in Ukraine through the prism of court decisions of Ukrainian courts of various instances and the relevant practice of the European Court of Human Rights. The methodological basis of the study is a set of philosophical and ideological, general and special scientific methods and techniques of scientific knowledge, including dialectical, systemic, structural and functional methods, as well as methods of analysis and synthesis. It is identified that the right to a fair trial in legal science, judicial practice is considered in its constituent elements and relevant manifestations, including fairness and publicity of the trial, compliance with the signs of independence, impartiality, legality, observance of the rule of law, equality of participants, and proceedings within reasonable time limits. Each of the elements, mentioned and features of the right to a fair trial is subject to appropriate interpretation in the context of the relevant decisions of the European Court of Human Rights during the review of case materials in national courts of the signatory states to the Convention.

REASONABLE TIME AND BANKRUPTCY OF SOCIALLY-OWNED ENTERPRISES

The subject matter of this paper is the bankruptcy of socially-owned enterprises. The aim is to examine the implications of bankruptcy proceedings against socially-owned enterprises on the budget of the Republic of Serbia and its taxpayers. The starting hypothesis is that the bankruptcies of socially-owned enterprises will have a significant negative impact on the budget of RS and its taxpayers. In order to test this hypothesis, we used the technique of descriptive statistics to determine the differences between the Commercial Courts in Belgrade, Niš and Kragujevac in terms of the average duration of bankruptcy proceedings, the maximum and minimum duration of cases, and the percentage of cases pending over four or three years. In addition, we provide a hypothetical calculation of the costs of the bankruptcy proceedings of all socially-owned enterprises in the three commercial courts in case the objection for the protection of the right to a trial within a reasonable time has been affirmed. The results show that there are no significant differences between the three commercial courts in the time dimension of the bankruptcy of socially-owned enterprises, given the fact that the vast majority of cases exceed the reasonable time limits and that such lengthy proceedings will significantly burden the RS budget.

Factors influencing decision-making to accept elective caesarean section: A descriptive cross-sectional study

Elective caesarean sections (CS) that have medical indications contribute to better pregnancy outcomes but women have to consent for the procedure to be performed within reasonable time limits for the desired outcomes. This study aimed to determine the factors that influence women's decision-making and the duration of the decision-making process to accept primary or repeat elective CS in a district hospital in Ghana.A descriptive cross-sectional study was conducted among 163 purposively-sampled postnatal women in a hospital, who had experienced a CS. A questionnaire was used to collect data after the women gave their consent to participate. Data was analyzed using SPSS version 25.0 and presented using appropriate descriptive statistics. Chi-square test of independence was done to determine the association between any two categorical variables.Major factors that influenced women's decision-making to accept elective CS were support from their husband/partner/relatives (39.3 %), their baby's life being at risk (24.5 %), history of previous CS and knowledge about the procedure (19.6 %). Age and parity had significant relationship with the influencing factors. However, age was only significant for the influence of husband/partner/relative in the decision-making to accept CS (p < 0.01). Age (R2 = 0.19, p < 0.001); previous CS (R2 = 0.14, p < 0.001) are the major predictors of the duration of the decision-making process.Women's decision-making in consultation with relatives is the main influencer to accept elective caesarean section. There is the need to involve relatives during the antenatal care period in order for younger women in particular to be readily supported to make timely decisions to avoid preventable complications and allay client's fears.

Knowledge-based approach for dimensionality reduction solving repetitive combinatorial optimization problems

This paper proposes a knowledge-based approach that combines case-based reasoning and operational research methodologies for solving repetitive combinatorial optimization problems. The novel approach makes use of past experience which is generally neglected in solving current optimization problems, and introduces this knowledge into operational research techniques for problem-solving, especially when the dimension of the problem is large and conventional schemes cannot solve it within a reasonable time limit. It greatly reduces the dimension of the problem and provides near-optimal solutions.

The disposition principle in civil proceedings

Shtefan A. The disposition principle in civil proceedings. The disposition (from the Latin «dispono» — to dispose) in the most general sense in the legal context means the ability to act at own discretion, to independently choose the direction of their behavior within the limits established by law. In different branches of law, the disposition has its own specific features but its basis is always that the subject of the relevant legal relationship is endowed with a certain freedom of choice in the exercise of their rights and independently disposes of them.The dispositive nature of civil proceedings has the following elements:1) civil proceedings in the case are based on the fact that its occurrence is possible only by virtue of the application of the person concerned to the court. The only grounds for initiating proceedings in the case is the submission of the application of the interested person in accordance with the requirements established by lawand in accordance with the procedure established by law;2) the court considers civil cases within the requirements stated in the case which include the requirements stated in the main claim, in a counterclaim, and in a third party claim;&#x0D; 3) consideration of civil cases is carried out solely on the basis of evidence submitted by the parties to the case or required by the court in cases provided by law. The main burden of filling the case with evidence rests with the parties to the case, and the court assists them in obtaining evidence by demanding it only in casesestablished by law;4) the party to the case, as well as the person who has legal capacity and in whose interests the claim is filed, disposes of their rights in relation to the subject matter of the dispute at their own discretion. This rule covers only procedural, not substantive rights, and applies only to rights relating to the subject matter of the dispute. In addition, the possibility of discretion of the party to the case in relation to their procedural rights on the subject matter of the dispute is allowed to the extent provided by procedural law;5) the court engages the relevant body or person that has the right to protect the rights, freedoms, and interests of others if the actions of the legal representative are contrary to the interests of the person he represents. In case of discrepancy between the interests of this person and the actions of his legal representative, the court is authorized to involve a body or person who is legally entitled to protect the rights, freedoms, and interests of others to participate in the case;6) the collecting of evidence in civil cases is not the obligation of the court except in cases established by procedural law. The court should not act in this direction instead of an inactive party to the case; the mandatory authority of the court to collect evidence is due to the direct indication of in which cases and what evidence is collected by the court itself;7) the court has the right to collect evidence relating to the subject matter of the dispute on its own initiative only in cases where it is necessary to protect minors or minors or persons who have been declared incompetent or whose capacity is limited, as well as in other cases provided by procedural law.The disposition as a basis of civil proceedings determines the only possible condition for the process of consideration of the case — the application of the interested person to the court, the limits of consideration of the case — stated by the interested person requirements, the basis of the case — evidence submitted by the parties or demanded by the court. The disposition also means the freedom of the party to dispose of their procedural rights in relation to the subject matter of the dispute, the absence of any obstacles to the implementation of such an order at its discretion. This freedom is not absolute and it has the statutory limits. Such limits are necessary for the effective functioning of the civil procedural form, in particular, the observance of reasonable time limits for civil cases and the prevention of abuse of procedural rights.Key words: disposition, disposition principle, civil proceedings

Bounds on efficient outcomes for large-scale cardinality-constrained Markowitz problems

When solving large-scale cardinality-constrained Markowitz mean–variance portfolio investment problems, exact solvers may be unable to derive some efficient portfolios, even within a reasonable time limit. In such cases, information on the distance from the best feasible solution, found before the optimization process has stopped, to the true efficient solution is unavailable. In this article, I demonstrate how to provide such information to the decision maker. I aim to use the concept of lower bounds and upper bounds on objective function values of an efficient portfolio, developed in my earlier works. I illustrate the proposed approach on a large-scale data set based upon real data. I address cases where a top-class commercial mixed-integer quadratic programming solver fails to provide efficient portfolios attempted to be derived by Chebyshev scalarization of the bi-objective optimization problem within a given time limit. In this case, I propose to transform purely technical information provided by the solver into information which can be used in navigation over the efficient frontier of the cardinality-constrained Markowitz mean–variance portfolio investment problem.

Mobile Media and Young Children's Cognitive Skills: A Review.

Though the use of mobile devices (eg, tablets, smartphones) by young children is pervasive and increasing, research relating children's use of mobile devices to their development is only beginning to emerge. Learning, language development, and self-regulation skills among children aged 0 to 5 are of particular interest to pediatric clinicians, researchers, parents, and policymakers, as these skills foreshadow important outcomes across the lifespan. Experimental research reviewed herein suggests that the interactivity allowed by mobile devices has benefits over passive viewing (for example, of television) for young children's learning and self-regulation, but studies of naturalistic use suggest increased use of mobile devices is associated with poorer language and self-regulation. Pediatric clinicians can be important sources of support for families endeavoring to navigate their children's use of mobile devices by providing advice and resources, such as communicating reasonable time limits and sharing sources of developmentally appropriate content. Future research should implement innovative, rigorous research designs and methods to clarify mechanisms underlying potential negative effects of naturalistic use of mobile devices by young children and investigate how content and context of young children's mobile-device use may influence relations between such use and children's skills.

Methodology for assessing the impact of institute on sustainable economic growth

The paper presents an overview of methodological approaches to the study of the influence of institutions on macroeconomic indicators characterizing long-term economic growth, although other indicators that are influenced by institutions can be identified: economic growth rate, GDP per capita, saving rate, and total factor productivity. The article analyzes the research of leading scientists conducted within the framework of the institutional theory that explains global inequality and some of its features. In addition to the institutional theory, two more theories compete to explain the causes of global inequality: geographical theory and the theory of cultural influence. Both of these theories are unpromising from the point of view of practical applicability, since geographical, climatic factors, cultural characteristics are not subject to the influence of economic policy within reasonable time limits. Institutional theory explains the inequality of countries by differences in their formal legal and informal social norms that govern the behavior of individuals and structure social interactions. The growing volume of empirical work of this kind has shown that institutions should be considered in the context of alternative approaches (culture and social capital, human capital), alternative econometric methods and alternative strategies for identifying the influence of institutions on macroeconomic indicators (long-term economic growth).
