Abstract:

Abstract We analyse the relationships between test scores, truancy and labour market outcomes for youths. Our econometric approach enables us to disentangle the observable direct and indirect effects of truancy and test scores on the risk of unemployment or ‘Not in Education, Employment or Training’ (NEET) from their unobserved effects. Using data for England and Wales, we show that models of youth unemployment and NEET that ignore the correlation between the unobservable determinants of test scores and truancy will lead to misleading inference about the strength of their effects.

The article is devoted to the study of the possibilities of mathematical methods and models that allow solving economic and financial problems. The issues of mathematical modeling in economics, solving financial problems through mathematical methods are considered. The author proves that studying economics using mathematical methods and models is more effective than using only theoretical apparatus. The language of mathematics allows us to substantiate economic phenomena that are important and necessary in economics. The use of mathematical applications to economic and financial issues has led

Abstract:

This study examines the impact of the determinants of new firm formation in New England at the county level from 1999 to 2009. Based on the Spatial Durbin panel model that accounts for spillover effects, it is found that population density and human capital positively affect single-unit firm births within a county and its neighbors. Population growth rate also exerts a significant positive impact on new firm formation, but most of the effect is from spatial spillovers. On the contrary, the ratio of large to small firm in terms of employment size and unemployment rate negatively influence singl

Abstract:

This article examines the problems of the development of united territorial communities, in particular, unemployment and economic problems. The object of the research is the improvement of territorial communities on the example of the Lviv region (Ukraine). One of the most problematic areas is the fact that communities, in most cases, do not have enough funds to solve economic and other problems. The study uses the idea of the need to create self-sufficient communities with a sufficient number of financial instruments for their own development.

Abstract:

The relevance of the study is justified by the importance of monitoring and forecasting the subsidisation of the Russian regions in order to identify the main criteria for classifying subjects on the basis of subsidisation. In a brief review of the literature, mathematical models used to model the subsidisation of the Russian regions are considered. They have mainly fixed socio-economic indicators that need to be given attention while applying, and also regression models are used, but mathematically sound recommendations for the withdrawal of regions from clusters of subsidisation are not prov

Abstract:

This paper deals with the construction of a discrete population mathematical model for the short-term forecast until January 2016 of the electoral support of extreme ideology parties in Spain. Firstly, the nontrivial concept of extreme ideology is stated. Then, the electoral register is split in three subpopulations: supporters of extremist parties, abstentions/blank voters, and supporters of establishment parties. The model takes into account the following variables: economy measured throughout the Spanish unemployment rate; demography quantified in terms of birth and death rates and emigrati

The emergence of antibiotic resistance in a wide variety of important pathogens of humans presents a worldwide threat to public health. This paper describes recent work on the use of mathematical models of the emergence and spread of resistance bacteria, on scales ranging from within the patient, in hospitals and within communities of people. Model development starts within the treated patient, and pharmacokinetic and pharmacodynamic principles are melded within a framework that mirrors the interaction between bacterial population growth, drug treatment and the immunological responses targeted

Abstract:

The past few decades by the emergence of such crises in the economic and social sphere of society, which resulted in economic supply shocks have been marked. Previously extremely rare, they have shifted the focus to the relevance of research on macroeconomic processes affected by shocks of this nature, not only in economic theory, but also in mathematical modelling. As a result of the analysis of already known macroeconomic models, it was revealed that the impact of external economic shocks on the main indicators of macroeconomics can have both negative and positive effects on economic growth.

The hemlock woolly adelgid (HWA; Adelges tsugae Annand) is causing widespread decline and mortality of eastern hemlock (Tsuga canadensis (L.) Carr.) throughout most of the range of eastern hemlock. Stem injection of insecticide is widely used as a chemical control measure, but the effectiveness of this method depends on the hydraulic characteristics of individual trees. We present data quantifying the distribution of water flux within the stems and the seasonal variability of daily water use of eastern hemlock trees growing in New England, U.S. and the southern Appalachians.

Mortality studies are essential in determining the health status and demographic composition of a population. The Lee–Carter (LC) modelling framework is extended to incorporate the macroeconomic variables that affect mortality, especially in forecasting. This paper makes several major contributions. First, a new model (LC-WT-ANFIS) employing the adaptive network-based fuzzy inference system (ANFIS) was proposed in conjunction with a nonlinear spectral model of maximum overlapping discrete wavelet transform (MODWT) that includes five mathematical functions, namely, Haar, Daubechies (d4), least

Mathematical and statistical models can be used to make predictions of how epidemics may progress in the near future and form a central part of outbreak mitigation and control. Renewal equation based models allow inference of epidemiological parameters from historical data and forecast future epidemic dynamics without requiring complex mechanistic assumptions. However, these models typically ignore interaction between age groups, partly due to challenges in parameterising a time varying interaction matrix. Social contact data collected regularly during the COVID-19 epidemic provide a means to

Therefore, it is becoming increasingly important to improve the living standards of the population and the use of artificial intelligence technologies in management systems.
