The Par-Tee site 35CLT20 , located on the northern Oregon Coast, is a large archaeological collection excavated in the s and s. Radiocarbon dates have been obtained on materials from the Par-Tee collection by researchers since the s, but these data have not been assessed for chronometric hygiene. To establish a reliable chronology for the Par-Tee site, we obtained new high-resolution accelerator mass spectrometry AMS radiocarbon dates and collagen peptide mass fingerprinting of cervid bones.
We evaluate the new radiocarbon dates along with previous radiocarbon dates from the site, using chronometric hygiene assessments and Bayesian statistics to build a refined chronology.

Dating Business Cycle Turning Points
Comparative analysis of a particular document against other documents from the same source and the same period may be of assistance in determining the relative date of documents or may identify a particular time frame in which a particular organisation used a particular paper type, printer, fax machine etc. There are various libraries of information available concerning when papers were produced but these rely very heavily on the presence of a watermark in the paper. Comparative analysis of a particular document against other documents from the same source and the same period may also be of assistance or may identify a particular time frame in which a particular organisation used a particular paper type.
Similarities in paper type, colour, content, fibres, sizes etc can yield valuable information when determining similarities or differences between papers. The types of pen, printers etc may be significant in assessing the date of a document and as with many of the dating techniques, the evidence is often more valuable or significant when an anachronism is established as opposed to compliance with other materials, papers etc which may have been available for a prolonged period of time.

Before there was swiping right, singles found love the old-fashioned way … in the personals section of the local paper. By Lisa Rabasca Roepe January 20, Initially, reading the weekly ads was a form of entertainment but, after a long-term relationship unexpectedly ended, I started perusing the ads to see if anyone sounded mildly appealing. The ad went on to mention two of my favorite activities—beer brewing and bike riding.
It seemed like a match made in heaven. Instead of simply swiping right, I had to call an answering machine and leave a message for the person who placed the ad.
Before there was swiping right, singles found love the old-fashioned way in the personals section of the local paper.
Have questions? Give us a call IPS Testing is able to determine likely age ranges for paper products by using wood fibers, pulping chemistry, paper additives and surface treatments to serve as dating markers. Our experienced fiber science team, led by Walter Rantanen, has developed an international reputation for paper and document forensics. While exact age dating of papers is not possible, the process is often able to exclude samples as being made in the time period of question.
Walter Rantanen has developed a large database of paper with known ages. He has also worked closely with Paul Messier and the Museum of Modern Art to develop a similar database for photographic papers. Typical paper forensic services that IPS provides to its U. Rantanen examined a large number of photos that were carefully dated to determine what fiber species and pulping processes were used from the early s through the late s.

The Problem of Digital Dating: DH2015 Paper
Madrid-Barcelona Km. In the forensic document examination field, document dating is one major challenge that still lacks validated methodologies. The variety of inks and papers, combined with different storage conditions, poses a complex problem when an estimation of age is needed. Although paper samples are mainly composed of cellulose, their chemical composition changes according to the manufacturing process and the raw materials.
When paper samples start degrading, differences in chemical profile can be identified.

ICGRD 2022: 16. International Conference on Geochronology and Radiocarbon Dating
First, we extend a commonly used dating procedure to allow for length, size and amplitude restrictions, and to compute the probability of a phase change. Second, we apply the modified algorithm for dating both the classical Euro area cycle and the deviation cycle, where the latter is obtained by a variety of methods, including a modified HP filter that reproduces the features of the BK filter but avoids end-point problems, and a production function based approach.
Third, we repeat the dating exercise for the main Euro area countries, evaluate the degree of syncronization, and compare the results with the UK and the US.
PDF | This work reviews the different analytical methods that have been proposed in the field of forensic dating of inks from different modern.
There are four major approaches each approach is a group of methods used for dating inks on documents:. Other ink entries are not necessary for comparison. Aginsky has developed the SET as a result of many years of research of the ink aging methodology developed and published by Dr. Antonio A. Cantu in the s. The second ink dating approach analyzes the chemical composition of inks on a contested document with the aim to determine whether these inks as well as other materials used to produce the document — paper, inkjet printing ink, toner, stamp pad ink, etc.
Such intra-comparisons of inks may reveal that the questioned entries were not written contemporaneously with the other entries in the file document. Comparison of the contested document to other similar documents from the same time frame — If other similar documents from the same source and pertinent time frame are available for comparison with the contested document, then:. Writing ink sequencing — Examining intersections areas where two or more pen lines cross to determine the order of writing it may prove that a particular entry was added at a later time.
Sequencing of indented impressions and writings — Examining intersections areas where the visible ink lines cross the indentations may determine the order of writing and thus prove that a particular entry was added at a later time. Paper folds — It is often possible to determine whether an ink line that intersects a paper fold was written before or after the paper was folded. Offset marks — When two pieces of paper are pressed together, marks such as writing and printing may be transferred from one to another.

The modern world provides two new ways to find love — online matchmaking and speed dating. In the last few years, these methods have moved from a last resort for the loveless to a more accepted way for millions to try to meet their mates. While this has led to dates, relationships and marriages around the globe, it has also been a boon for enterprising researchers — providing huge datasets chronicling real world behavior. For millions of years, humans have been selecting mates using the wealth of information gleaned in face-to-face interactions — not just appearance, but characteristics such as tone of voice, body language, and scent, as well as immediate feedback to their own communications.
Does mate selection differ when those looking are presented with an almost overwhelming number of potential partners, but limited to a few photos, statistics, and an introductory paragraph about each one?

This paper presents a study into the potential of visible spectroscopy with chemometrics as an approach to dating blue ball tip inks on paper documents. Analysis of six inks left under various conditions found that the majority of those kept in the dark could still be matched to the source pen after 32 months of ageing. Conversely, the majority of those exposed to light exhibited rapid spectral changes that continued throughout the 32 month period.
Partial least squares regression PLSR was used to generate dating models for inks aged with exposure to light. Evaluation using an external test set found absolute dating to be challenging for these ink deposits within the first 2—6 months of ageing. However, predictive accuracy was found to improve for long-term ageing, with two-year old samples yielding age estimates with a maximum error of 6 months.
This rapid, non-destructive methodology could assist document examiners in the relative ageing or approximate age determination of questioned documents, as well as the identification of document alterations.

This paper discusses formal quantitative algorithms that can be used to identify business cycle turning points. An intuitive, graphical derivation of these algorithms is presented along with a description of how they can be implemented making very minimal distributional assumptions. We also provide the intuition and detailed description of these algorithms for both simple parametric univariate inference as well as latent-variable multiple-indicator inference using a state-space Markov-switching approach.
We illustrate the promise of this approach by reconstructing the inferences that would have been generated if parameters had to be estimated and inferences drawn based on data as they were originally released at each historical date.

Using a miniaturized near infrared spectrometer associated to chemometrics we developed a rapid and non destructive procedure to characterise paper and investigate its aging with the aim of solving dating problems. Two sets of paper were considered in this study books and sheets in order to ensure the results are not dependent of the storage conditions.
The MicroNIR has the ability to distinguish paper according to the chemical composition of the surface as a function of the period of manufacturing. The optimized analytical platform is fast and simple, avoiding sample pre-treatment procedures. As a consequence, the approach may be considered as the optimal technology to carry out analysis of ancient paper or other similar materials for diagnostic or forensic purposes as it is entirely portable and non-destructive.
