TL;DR: This paper reviews five approaches to informing ABMs, provides a corresponding case study describing the model usage of these approaches, the types of data each approach produces, thetypes of questions those data can answer, and an evaluation of the strengths and weaknesses of those data for use in an ABM.
Abstract: The use of agent-based models (ABMs) for investigating land-use science questions has been increasing dramatically over the last decade. Modelers have moved from ‘proofs of existence’ toy models to case-specific, multi-scaled, multi-actor, and data-intensive models of land-use and land-cover change. An international workshop, titled ‘Multi-Agent Modeling and Collaborative Planning—Method2Method Workshop’, was held in Bonn in 2005 in order to bring together researchers using different data collection approaches to informing agent-based models. Participants identified a typology of five approaches to empirically inform ABMs for land use science: sample surveys, participant observation, field and laboratory experiments, companion modeling, and GIS and remotely sensed data. This paper reviews these five approaches to informing ABMs, provides a corresponding case study describing the model usage of these approaches, the types of data each approach produces, the types of questions those data can answer, and an ...

TL;DR: The authors proposed several deductive imputation procedures to improve the education variable in the IAB employment subsample by using multiple education information available in the data because the employees' education is reported at least once a year.
Abstract: The education variable in the IAB employment subsample has two shortcomings: missing values and inconsistencies with the reporting rule We propose several deductive imputation procedures to improve the variable They mainly use the multiple education information available in the data because the employees' education is reported at least once a year We compare the improved data from the different procedures and the original data in typical applications in labor economics: educational composition of employment, wage inequality, and wage regression We find, that correcting the education variable: (i) shows the educational attainment of the male labor force to be higher than measured with the original data, (ii) gives different values for some measures of wage inequality, and (iii) does not change the estimates in wage regressions much

TL;DR: In this article, a four-year field trial was conducted on one site in south-western Germany to compare and evaluate the biomass and energy yield performance of important energy crops, including short rotation willow coppice, miscanthus, switchgrass, energy maize and two different crop rotation systems including winter oilseed rape, winter wheat and winter triticale.

TL;DR: This work applied so-called radiocarbon wiggle-matching to a carbon-14 sequence of tree-ring segments to constrain the eruption date of Santorini to the range 1627‐1600 B.C. with 95.4% probability.
Abstract: Precise and direct dating of the Minoan eruption of Santorini (Thera) in Greece, a global Bronze Age time marker, has been made possible by the unique find of an olive tree, buried alive in life position by the tephra (pumice and ashes) on Santorini. We applied so-called radiocarbon wiggle-matching to a carbon-14 sequence of tree-ring segments to constrain the eruption date to the range 1627-1600 B.C. with 95.4% probability. Our result is in the range of previous, less precise, and less direct results of several scientific dating methods, but it is a century earlier than the date derived from traditional Egyptian chronologies.

TL;DR: In this paper, the authors summarized the available data and theories on forms and formation processes of pedogenic carbonates and relate them to environmental factors, and suggested the most important future research directions on PC, including the anthropogenic effects of fertilization and soil management.
