In this paper we model the role of a government of a large population as a mean field optimal control problem. Such control problems are constrained by a PDE of continuity-type, governing the dynamics of the probability distribution of the agent population. We show the existence of mean field optimal controls both in the stochastic and deterministic setting. We derive rigorously the first order optimality conditions useful for numerical computation of mean field optimal controls. We introduce a novel approximating hierarchy of sub-optimal controls based on a Boltzmann approach, whose computation requires a very moderate numerical complexity with respect to the one of the optimal control. We provide numerical experiments for models in opinion formation comparing the behavior of the control hierarchy. ; ERC advanced Grant 668998 (OCLOC) ; (VLID)2523620
It is important to monitor and assess the physiological strain of individuals working in hot environments to avoid heat illness and performance degradation. The body core temperature (Tc) is a reliable indicator of thermal work strain. However, measuring Tc is invasive and often inconvenient and impractical for real-time monitoring of workers in high heat strain environments. Seeking a better solution, the main aim of the present study was to investigate the Kalman filter method to enable the estimation of heat strain from non-invasive measurements (heart rate (HR) and chest skin temperature (ST)) obtained 'online' via wearable body sensors. In particular, we developed two Kalman filter models. First, an extended Kalman filter (EFK) was implemented in a cubic state space modelling framework (HR versus Tc) with a stage-wise, autoregressive exogenous model (incorporating HR and ST) as the time update model. Under the second model, the online Kalman filter (OFK) approach builds up the time update equation depending only on the initial value of Tc and the latest value of the exogenous variables. Both models were trained and validated using data from laboratory- and outfield-based heat strain profiling studies in which subjects performed a high intensity military foot march. While both the EKF and OKF models provided satisfactory estimates of Tc, the results showed an overall superior performance of the OKF model (overall root mean square error, RMSE = 0.31°C) compared to the EKF model (RMSE = 0.45°C).
The Government of Montenegro nationalized 2030 Agenda on Sustainable Development by adopting the National Strategy for Sustainable Development (NSSD) in 2016, together with a corresponding Action Plan for its implementation. The NSSD is umbrella, horizontal and long-term development strategy of Montenegro that relates not only to environment and economics, but also to human resources, valuable social capital that should ensure prosperous development, recommendations for establishing the framework of financing and governance for sustainable development. The NSSD represents strategic framework for the transposition of the UN sustainable development goals (SDGs) and its indicators into national context. The NSSD Action plan, divided into 6 thematic areas with 30 strategic goals of sustainable development of Montenegro and their 102 measures and 601 sub-measures, represents very complex mechanism for monitoring and reporting about achieving the UN sustainable development goals (SDGs) in Montenegro. Hence, measuring progress in the NSSD implementation is the focus of this research. Effective measuring of the progress in the NSSD implementation could be achieved under the following preconditions: developed coordination mechanism for reporting, methodology of designing indicators, IT support for data collection and reporting, and strengthening of inter-linkages between the EU agenda and UN 2030 Agenda.
The study aims to develop a mathematical model that can explain the effect of national defense on economic growth from various works of literature and developments. The overall impact of military spending on growth can be analyzed by dividing the economy into sectors. We wish to demonstrate the formation of a general mathematical model. The model building is based on the neoclassical production function approach developed by Feder and Deninson. The source of Deninson's growth model uses a supply-side description of changes in aggregate output. It describes aggregate growth in terms of changes in capital and labor. The resulting aggregate growth equation shows the combination of externality and productivity effects.
Метою статті є ретроспективний аналіз розвитку прикладної спрямованості навчання математики в школах України. Для досягнення поставленої мети використовувалися такі теоретичні методи дослідження, як аналіз науково-методичної літератури різних історичних періодів; узагальнення, систематизація, порівняльний і системний аналіз результатів. Установлено, що на різних стадіях розвитку системи математичної освіти зберігається стійкий інтерес до проблеми зв'язку курсу математики з практикою, проте цілі і зміст предмету математики змінюється в залежності від домінувальних у суспільстві уявлень про місце і роль математики в системі національних цінностей у певний історичний період розвитку. Практичне значення даного дослідження полягає в тому, що для успішної реалізації прикладної спрямованості навчання математики дуже важливим є процес вивчення попереднього досвіду, пов'язаного з певними її аспектами. ; The purpose of the article is a retrospective analysis of the development of applied mathematics teaching in Ukrainian schools. To achieve this goal, the following theoretical research methods were used: analysis of scientific and methodological literature of different historical periods; generalization, systematization, comparative and systematic analysis of results. It is established that at different stages of development of the mathematical education system there is a persistent interest in the problem of linking the course of mathematics with practice, but the purpose and content of the subject of mathematics varies depending on the dominant in society ideas about the place and role of mathematics in the system of national values in a certain historical period of development. For example, in Cossack times, in Cossack schools, mathematics was used to produce many types of Cossack weapons and military transport. Later, in Soviet times, the development of Ukrainian mathematical education took place against the backdrop of Soviet revolutionary views. In the early twentieth century Mathematics was completely dissolved in social work. The tasks of that period were more like certain instructions for performing specific life exercises. Subsequently, in the mathematical education began to dominate the "principle of polytechnism", which involved the connection of mathematics with production and developing students' ability to use the acquired mathematical knowledge to build a communist society. But in the late 70s of the twentieth century, there was a shift in emphasis and along with the ideas began to actively develop the problem of implementing the applied orientation of the mathematics course. The recent history of the applied orientation of mathematics teaching of fundamental changes has come closer to our times. Since 2012, the content of mathematics teaching was based on a competence approach, and in 2016, Ukraine began reforming the education system and implementation of the New Ukrainian School, the key features of which are the pedagogy of partnership, readiness for technological and procedural innovations, new learning standards, connected with life. Thus, having passed the path from the era of Kievan Rus to the present day, the applied orientation of mathematics education has transformed into the process of developing a new system of mathematical education, which is organically combined with the introduction of STEM-learning and implementation of completely innovative approaches to the organization of the educational process. The practical value of this study is that the process of learning from previous experiences related to certain aspects of it is very important for the successful implementation of the applied focus of mathematics teaching.
The 2018–2020 Ebola virus disease epidemic in Democratic Republic of the Congo (DRC) resulted in 3481 cases (probable and confirmed) and 2299 deaths. In this paper, we use a novel statistical method to analyze the individual-level incidence and hospitalization data on DRC Ebola victims. Our analysis suggests that an increase in the rate of quarantine and isolation that has shortened the infectiousness period by approximately one day during the epidemic's third and final wave was likely responsible for the eventual containment of the outbreak. The analysis further reveals that the total effective population size or the average number of individuals at risk for the disease exposure in three epidemic waves over the period of 24 months was around 16,000–a much smaller number than previously estimated and likely an evidence of at least partial protection of the population at risk through ring vaccination and contact tracing as well as adherence to strict quarantine and isolation policies.
This work provides a comprehensive implementation plan of a carbon credits program for Pullanta. Analyses on our designed carbon credits program under a cap-and-trade system demonstrate that under the premise of having 90% certainty of achieving the reduction goal, the government can generate income through the financial instruments for investments in climate change mitigation efforts in the future.
Bibliography: p. 221-233. ; This thesis is concerned with the problem of how to effectively address the complex issue of poverty in the context of limited resources. Poverty is a multi-dimensional problem that affects different communities in different ways. In order to use the available resources in such a way as to most effectively tackle poverty, a means of measuring and benchmarking outcomes as well as evaluating choices of intervention is required. However, smart methods of allocating scarce resources are not in themselves sufficient, if they are not regarded as legitimate by the participants of the process. The imperative of legitimacy demands that we both address the issue of quantitative rigour in resource allocation methods and that we look beyond and explore too the mechanics of effective participatory methods. The approach of developmental local government adopted by the new South African government post apartheid, places this complex problem in the sphere of local government. The primary tool available to local administrators for addressing poverty, amongst other issues, is that of integrated development planning. This process draws together the stakeholders who fall broadly into three groups of participants, namely the communities that live in the municipality, the municipal officials and the elected politicians, and allocates them the task of identifying and prioritising community and municipal issues, and developing appropriate plans to address them. This package of plans or projects is compiled into a municipal budget that targets priority issues for the area, in an integrated and coherent manner. This thesis proposes a new method for tackling this specific group decision making problem, namely Participative Multi-Criteria Decision Analysis. This method was developed in an action research setting in the municipality of Stellenbosch, South Africa, and applied to their 2001/2002 integrated development planning process. The method is grounded in the principles of participative action research in which the participation of all interested and affected patties is valued, and in which there is a commitment to work for change to the fundamental fabric of knowledge and power, leading to a greater empowerment of ordinary people. This participative framework strengthens the legitimacy of the approach by promoting a stronger sense of ownership of process and products by all participants. Within this participative framework, tools of multi-criteria decision analysis are used to support the decision making process by quantifying difficult decisions that need to be addressed. It is the synthesis of these two approaches (action research and multi-criteria decision analysis) that provides both legitimacy and rigour for this method within a highly contested and complex public decision making arena. In the spirit of action research, the method is developed by drawing on theory about developmental local government and poverty, as well as multi-criteria decision analysis. In the process of the research, over forty community workshops were held throughout the Stellenbosch municipal area. Community representatives identified and prioritised the issues of their areas; and in conjunction with municipal officials, developed and evaluated projects in response to these issues. These evaluations assisted the local council to compile the final budget for 2001/2002 in Stellenbosch. In this process, the communities (divided into nine development areas) also developed community development measurement scales which formed the basis for the project evaluations and an ongoing basis for monitoring progress in these communities. It unfolded during the course of this research that a fundamental component of this proposed participative public decision making approach is the role of a central co-ordinating person, not connected to or answerable to any of the constituent groups, who can manage the process of participation, promote an awareness of effective and informative data; ensure the appropriate use of quantification tools and maintain a focus on sustainable poverty alleviation. The method developed in this thesis was successfully applied to the process of identifying, prioritising and making choices about community issues in Stellenbosch, under conditions of significant polarisation of the constituent decision making groups, conclude that this method can be used to implement key aspects of integrated development planning as it addresses the issues of legitimacy and rigour in participative public decision making.
The dissertation studies the influence of military mass mobilization on the top income shares in the society, and therefore on inequality levels, in the United States and Europe over the last one hundred years. More precisely, one of the main results in this work shows that when the individual external fighting effort in a conflict with another country is high, thus during military mass mobilization, then the internal fighting efforts for appropriation or rent seeking between rich and the rest of the society decrease, and in turn the inequality levels inside the society are lower. On the contrary, during periods of professional army, thus when the individual external fighting effort is low, then inside the society the internal fighting efforts for appropriation or rent seeking between rich and the rest of the society increase, and in turn the inequality levels increase. These implications are shown using models of inequality and conflict that are based on contest success functions. The dissertation also includes statistical evidence in support of the main hypothesis of this work. Several statistical tests are presented that show that periods of conscription are correlated with low levels of the top 1 and top 10 percent income shares using data over the last one hundred years. The dissertation ends with an analysis of the cases considered from North America and Western Europe. A comparative analysis and difference in difference method is employed to distinguish between different periods and systems.
PUBLISHED ; Motivated by the notorious di culties in determining the rst quantum corrections to the spectrum of short strings in AdS 5 S 5 from rst principles, we study closed bosonic strings in this background employing a static gauge. In this gauge the world-sheet Hamiltonian density is constant along the extension of the string and directly proportional to the square of the spacetime energy. We quantize this sys- tem in a minisuperspace approach, in which we consider only a single AdS 5 string mode excitation next to an arbitrary particle like zero-mode contribution in the full AdS 5 S 5 background. We determine the quantum spectrum using this method to the next-to-next-to-leading order in the large 't Hooft coupling expansion. We ar- gue for an ordering prescription which should arise from supersymmetrization and indeed recover the integrability based predictions for the spectrum of the lightest excitation, dual to the Konishi eld scaling dimensions. The higher excitations fail to agree, but this is shown to be a consequence of the string mode truncation employed. Despite this simple setup, our system reveals intriguing features, such as a close connection to particles in AdS 6 , classical integrability and preservation of the isometries of AdS 5 S 5 at the quantum level ; We thank Harald Dorn, Chrysostomos Kalousios, Thomas Klose, Joe Minahan, Jonas Pollok and Tristan McLoughlin for useful discussions.
