Dealing With Inbuilt Age: A Bayesian Approach to Radiocarbon Dating of Rice, Bamboo and Charcoal From Non Ban Jak, Thailand

open access: yesArchaeometry, EarlyView.
ABSTRACT New radiocarbon determinations from rice grains and bamboo have been obtained from Non Ban Jak, Northeast Thailand. These, along with charcoal, date a late Iron Age building sequence. The results come from short‐lived species and charcoal with potential inbuilt age. We built a series of Bayesian models to obtain a reliable chronology.

Problem‐Solving Strategies for Creativity in Business Model Design: A Configurational Study

open access: yesJournal of Management Studies, EarlyView.
Abstract We study how individuals develop mental representations of how a business may create and capture value. Specifically, we analyse how different configurations of problem‐solving strategies lead to creative business models. We observe the design process of 101 experienced business‐model designers in real time, using think‐alouds.

Splitting necklaces

open access: yesAdvances in Mathematics, 1987
Let N be an opened necklace with \(k\cdot a_ i\) beads of color i, \(1\leq i\leq t\). A k-splitting of this necklace is a partition of the necklace into k parts, each consisting of a finite number of nonoverlapping intervals of beads whose union captures precisely \(a_ i\) beads of color i, \(1\leq i\leq t\).
