Abstract (sommario):
The aggressiveness of an extensive collection of strains of Erwinia amylovora was analyzed using immature fruit and detached pear flower assays under controlled environmental conditions. The analysis was performed by means of a quantitative approach based on fitting data to mathematical models that relate infection incidence to pathogen dose and time. Probit and hyperbolic saturation models were used for disease-dose relationships and provided information on the median effective dose (ED50). Values of ED50 ranged from 103 to 106 CFU/ml (10 to 104 CFU per site of inoculation). A modified Gomper

Abstract (sommario):
Digital control of breeding process, creation of mathematical models of living objects and management of plant life cycle is an urgent problem of modern times. Сreation of technologies that ensure implementation of the concept of advanced digital "smart" agriculture is impossible without basic mathematical models of "mass interactions" of natural living objects. This primarily affects the spread of certain diseases in populations. In the plant world, such a convenient model object is the well-studied "host-pathogen" system by the example of the interaction of millet and its smut disease. At pr

Abstract (sommario):
In São Paulo State, mainly in rural areas, the utilization of wooden poles is observed for different purposes. In this context, wood in contact with the ground presents faster deterioration, which is generally associated to environmental factors and, especially to the presence of fungi and insects. With the use of mathematical models, the useful life of wooden structures can be predicted by obtaining "climatic indexes" to indicate, comparatively among the areas studied, which have more or less tendency to fungi and insects attacks. In this work, by using climatological data of several cities a

Abstract (sommario):
Modeling mathematical operations using pictures and other concrete materials is a valuable technique to help children develop an understanding of mathematical concepts. A teacher feels secure that a child understand an algorithm when the child can build or draw a model of it. But a model that work for one child, that is, one that helps him or her to see a solution more easily, may make a problem seem more difficult for another child.

Abstract (sommario):
An analysis of secondary students’ personality traits, along with a description of their emotional intelligence levels and their anger control, could be decisive when educating students to prevent anti-social behavior in academia. Very few studies on personality, emotional intelligence, and aggressive conduct exist in Spain. Some of the studies that do exist, however, only explore the relationship between emotional intelligence, personality, and prosocial behavior in secondary education students. Likewise, there are few studies focusing on personality and aggression control. In this study, usi

Abstract (sommario):
Shape and form are often used as mathematical models of situations. For example, teachers explain that light travels in a line or that the shadow cast by a person is related by similar triangles to that cast by a flagpole. Yet despite the common use of mathematical models in the sciences and in design professions, children rarely have the opportunity to participate in this form of mathematical thinking. In this article, we describe how first and second graders modeled a “fair” playing space in a game of tag called “Mother, may I?” The children modeled the playing space by using a succession of

Abstract (sommario):
Zero-inflated (ZI) count data models overcome the restriction of equality relationship between mean and variance, but functional relationship still exists. For ZI models it is important to know whether the proportion of zeros and the rate of counts have any influence on the fit of the model. In this study we have considered three zero-inflated models, namely, ZIP, ZINB, and Hurdle model. We also considered Poisson and negative binomial model as classical count data models. Our simulation experiment suggests that the proportion of zeros for given rate parameter does not a↵ect the fit of the mod

This dissertation consists of three empirical essays investigating different aspects of health care for children and families. The first essay examines the effectiveness of adherence to American Academy of Pediatrics guidelines for preventive pediatric health care. Using a national longitudinal sample of children age two years and younger, we investigate whether compliance with prescribed periodic well-child care visits has beneficial effects on child health. We find that increased compliance improves child health. In particular, higher compliance lowers future risks of fair or poor health, of

Children are an often overlooked and understudied population group, whose travel needs are responsible for a significant number of trips made by a household. In addition, children’s travel and activity participation have direct implication for adults’ activity-travel patterns. A better understanding of children’s activity-travel patterns and the linkages between parents and children’s activity-travel needs is necessary for accurate prediction and forecasting of activity-based travel demand modeling systems. In contrast to the need to examine and model children’s activity-travel patterns, exist

Abstract (sommario):
Terminology is one of the constituents of the scientific knowledge system. Mastering terminology means to learn the extent and content of notions, and also to use these terms in work. The problems of terminology formation were studied by Bogoyavlensky, Galperin, Talyzina. In the studies of Vygodsky, the inner speech derives from conversational speech in a way of changing its function and consequently its structure. Though there has not been developed complete methodic conception of forming terminology apparatus in children, the chapter is intended to describe a model that forms mathematical terminology apparatus in the process of teaching. The main methods of studies were psychology literature analysis, educational process analysis (teaching mathematics), watching and testing elementary school children in Russia.

Abstract (sommario):
Vargas’s work focused on children´s autonomous activities as well as on their intrinsic motivation in mathematics classrooms and was designed in the sense of the so-called genetic method (Ambrus & Vancsó, 2017, p. 7). His goal was to enable learners to discover mathematics in various every-day situations and to find appropriate mathematical models (Ambrus & Vancsó, 2017, p. 10). In a playful way, he wanted to convey methods, models and basic concepts of mathematics and especially the rules of logic. However, a main and basic area of mathematics, which also should be communicated to children from the very beginning, and which is not independent of logics, is the area of arguing and proving in mathematics. The question, how Varga placed and communicated arguments and proofs suitable for 1st-to-4th-grade learners, will be answered by analysing his German-language book Engel, Varga & Walser (1974). In this issue, two of his favourite mathematical areas, namely combinatorics and probability theory are brought to bear.

Abstract (sommario):
In this paper, we are dealing with problems that have been discussed with prospective mathematics teachers to make them discover methodological opportunities and pitfalls at different levels of problem solving. We have chosen topics which are in themselves interesting for children, because they can be introduced playfully with concrete activity, they require little mathematical knowledge at the start, and their conscious discussion is also important for mathematical activities and applications of mathematics. We will show in Chapter 2 how the games lead to the Fibonacci series and the Pascal triangle, and in Chapter 3, how to get from paper folding to dragon curves. Classification: A30, D50. Keywords: manipulative materials and their use in problem solving (visualizations, models, educational games, paper folding), Fibonacci sequence, Pascal triangle, dragon curve.

Abstract (sommario):
Congenital heart disease (CHD) affects about 1% of newborn babies in the US, and is the leading cause of non-infectious death in children. Abnormal blood flow dynamics during early development can lead to CHD. Although the effect of hemodynamic conditions on cardiac development — even under normal conditions — has been widely accepted, the mechanisms by which blood flow influences cardiac cell responses are only starting to emerge. Mathematical models of cardiac growth could then help elucidate key aspects of cardiac development.
