title: Data indicating patterns in the scientific production of long-term ecological research

description: A systematic accounting of the scientific production of long-term ecological research (LTER) from the principal investigator level to the global scale is lacking. Such information is useful for evaluating the performance of this kind of research program, identifying its control factors, and increasing the resilience of LTER by targeted action at the needed levels of social complexity. Here, I report the data from the investigation in the Web of Science and the subsequent processing. The data has an indicator value for patterns of LTER’s production.

The data describe five dependent variables (Total number of articles by a political entity, Number of authors from a political entity citing articles of other authors or on a topic, Percent of articles in a set with keywords belonging to a class of keywords, Number of articles by year in a set, Number of articles in a five-year period in a set with keywords belonging to a class of keywords), one variable for evaluating the value of indicators of the first independent variable (Total number of articles for validation by a political entity, extracted from a past analysis of the LTER scientific production), and three independent variables used in the data processing (Number of LTER sites in a political entity, Gross domestic product in 2022 (USD), Research and development (RD) expenditure (% of GDP)).

The first sheet outlines the method for obtaining data for the mentioned variables. The second sheet presents 33 sets of articles processed to obtain the data, along with methodological details and acronyms. The remaining sheets contain the data.

The data have been processed for the presentation:

·       Iordache, V., Groffman, P., 2025, Increasing the resilience of long-term ecological research, COS 013-04, The Annual Meeting of the Ecological Society of America, Baltimore, USA.

The data will be used for the production of a subsequent article.

The value of the data lies in its use as a methodological model for extending analyses to other principal investigators, countries, regions, or types of research infrastructures, and as a reference for future analyses and trend interpretation.

title: Supplementary Materials "How we think about numbers - Early counting and mathematical abstraction" - Chapter 3

description: Supplementary Materials for Chapter 3 of the Doctoral Dissertation "How we think about numbers - Early counting and mathematical abstraction". Contains open data and materials.As children learn to count, they make one of their first mathematical abstractions. They initially learn how numbers in the count sequence correspond to quantities of physical things if the rules of counting are followed (i.e., if you say the numbers in order “one two three four …” as you tag each thing with a number). Around the age of four-years-old, children discover that these rules also define numbers in relation to each other, such that numbers contain meaning in themselves and without reference to the physical world (e.g., “five” is “one” more than “four”). It is through learning to count, that children discover the natural numbers as mathematical symbols defined by abstract rules.In this dissertation, I explored the developmental trajectory and the cognitive mechanisms of how we gain an understanding of the natural numbers as children. I present new methodological, empirical, and theoretical insights on how and when in the process of learning to count, children discover that numbers represent cardinalities, that numbers can be defined in relation to each other by the successor function and that numbers refer to units. Lastly, I explore this mathematical abstraction as the foundation of how we think about numbers as adults.My work critically tested prominent theories on how learning to count gives meaning to numbers through analogical mapping and conceptual bootstrapping. Findings across five empirical studies suggest that the process is more gradual and continuous than previous theories have proposed. Children begin to understand numbers as cardinalities defined in relation to other numbers by the successor function before they fully grasp the rules of counting. With learning the rules of counting this understanding continuously expands and matures. I further suggest that children may only fully understand numbers as abstract mathematical symbols once they understand how counting and numbers refer to the abstract notion of units rather than to physical things.The central finding of this dissertation is that learning to count does not change children’s understanding of numbers altogether and all at once. Nonetheless, when learning to count, children accomplish a fascinating mathematical abstraction, which builds the foundation for lifelong mathematical learning.© Theresa Elise Wege, CC BY-NC 4.0<br>
