Tephra layers are valuable stratigraphic and chronological markers in palaeoenviromental studies. Establishing robust linkages require complete comparative databases of eruptive events to ensure that potential correlatives are not overlooked. This is achieved through the construction of tephrostratigraphical inventories proximal to the volcanic source. Proximally-characterised ash layers are fr...

A lean manufacturing simulation model was created that replicated the existing assembly system as well as a potential system of similar capacity that modified the existing design to incorporate lean manufacturing shop-floor principles. Arena’s manufacturing simulation software generated performance statistics for both systems and measured each system’s resource requirements and performance in t...

Recent research on stimulability and generalization suggests that treatment of nonstimulable sounds results in maximum treatment gains (Powell, Elbert, & Dinnsen, 1991). It has also been suggested, however, that nonstimulable sounds are more difficult to teach, especially to young children with very small phonetic inventories. In this article, we describe a treatment program designed to increas...

Pauling's suggestion that enzymes are complementary in structure to the activated complexes of the reactions they catalyze has provided the conceptual basis to explain how enzymes obtain their fantastic catalytic prowess, and has served as a guiding principle in drug design for over 50 y. However, this model by itself fails to predict the magnitude of enzymes' rate accelerations. We construct a...

Both the magnitude and the urgency of the task of assessing global biodiversity require that we make the most of what we know through the use of estimation and extrapolation. Likewise, future biodiversity inventories need to be designed around the use of effective sampling and estimation procedures, especially for 'hyperdiverse' groups of terrestrial organisms, such as arthropods, nematodes, fu...

Sense inventories for polysemous predicates are often comprised by a number of related senses. In this paper, we examine different types of relations within sense inventories and give a qualitative analysis of the effects they have on decisions made by the annotators and annotator error. We also discuss some common traps and pitfalls in design of sense inventories. We use the data set developed...

The control policies that are used in inventory management systems assume that orders arrive in the same sequence as they were ordered. Due to changes in supply chains and markets, this assumption is no longer valid. Therefore, traditional control policies have to be modified in order to be able to manage inventories in case of order crossovers. This paper aims at providing an improved understa...

Taxonomic inventories (or species censuses) are the most elementary data in biogeography, macroecology and conservation biology. They play fundamental roles in the construction of species richness patterns, delineation of species ranges, quantification of extinction risk and prioritization of conservation efforts in hot spot areas. Given their importance, any issue related to the completeness o...

Theoretical models have been ambiguous on the relationship between industry competition and inventory holdings of manufacturing firms. Facing competition, on the one hand, firms may desire to hold more inventory to avoid losing sales to competitors; on the other hand, firms strive to improve inventory turns to control costs and stay competitive. Using U.S. Census data on manufacturing industrie...
