Temporal record linkage is the process of identifying groups of records which are collected over long periods of time, such as census databases or voter registration databases, that represent the same real-world entities. These datasets often contain temporal information for each record, such as the time when a record was created, or the time when it was modified. Unlike traditional record link...

The most notable trend in the sedimentary iron isotope record is a shift at the end of the Archean from highly variable δ56 Fe values with large negative excursions to less variable δ56 Fe values with more limited negative values. The mechanistic explanation behind this trend has been extensively debated, with two main competing hypotheses: (i) a shift in marine redox conditions and the transit...

The census of agriculture is an important source of statistics about the Nation’s agricultural production and provides consistent, comparable data at the county, state, and national levels. Each census record has weights which are used to produce totals for the entire population. The process of rounding weights to integer values has been in place for the last several censuses. When a record’s w...

We have generated a high-resolution coral D14C record from the southwest subtropical Pacific spanning the last 50 yr. Prebomb (1950–1956) D14C values average -52‰. Values begin to increase in 1957, reaching a maximum in the early 1970s, about 10 yr after the atmospheric peak. There is a consistent 10-15‰ seasonal cycle whose relationship with vertical mixing evolves as a consequence of the pene...

It is known there are some similarities between order statistics and record values, moreover, when viewed as point processes, the two processes both share the order statistics property. These motivated us to investigate some intrinsic properties within the class of order statistics point processes, which in turn lead to some useful characterizations by using certain conditional moment of the sp...

The destruction wrought by North Atlantic hurricanes in 2004 and 2005 dramatically emphasizes the need for better understanding of tropical cyclone activity apart from the records provided by meteorological data and historical documentation. We present a 220-year record of oxygen isotope values of alpha-cellulose in longleaf pine tree rings that preserves anomalously low isotope values in the l...

Imputed micro data often contain conflicting information. The situation may e.g., arise from partial imputation, where one part of the imputed record consists of the observed values of the original record and the other the imputed values. Edit-rules that involve variables from both parts of the record will often be violated. Or, inconsistency may be caused by adjustment for errors in the observ...

As part of an ongoing project to evaluate elite track and field throwers in the United States, the javelin competition was filmed during the 1983 Pepsi Invitational Track Meet. A high-speed video camera (Spin Physics SP2000) was positioned orthogonal to the javelin runway to record the release of all throws. During this competition, Tom Petranoff s world record (99.72 m) was filmed at 200 field...
