The basic premise of mortar dating by OSL is that quartz in the sand used for making mortar has been optically zeroed during the preparation process optical bleaching. The moment to be dated is the last exposure of sand grains to light, before being embedded within the masonry and hidden from light.
Online Dating Industry: The Business of Love
Due to the real and perceived dangers of online dating, the stigma that surrounds it, and the pervasiveness of it, it is a great lens through which folks can be introduced to the core principles of threat modeling. Isaiah Sarju has used online dating sites such as Tinder and OkCupid. At times this seems antithetical to his stance on privacy and security. To better understand the security ramifications of online dating, and to establish safe methods of doing it, he applied threat modeling to online dating.
Through this he came up with a set of best practices depending on your threat model. This talk is relevant for anyone who is trying to balance privacy and security and a desire for human connection in this modern world.

We receive many inquiries from people who have been defrauded for hundreds and sometimes thousands of dollars by Internet contacts they thought were their friends or loved ones. Internet con artists try to convince you to send them money. In many cases, scammers troll the Internet for victims, and spend weeks or months building a relationship. Before you send any money, check to see if you recognize any of the following signs that you may be a potential victim of a scam:.
The U. Embassy in Kyiv receives numerous reports from U. Often, these scams will result in requests for increasing amounts of money for various purposes, including many noted above.

Academy Award winner Ben Affleck will join a star-studded lineup for their inaugural pop-culture themed Celebrity Fan Fest event. Maybe Shauna Sexton has learned a powerful lesson about the hazards of dating an A-list movie star who is in the midst of a mid-life crisis. Oh, and Warner Bros. The studio opted to rethink its approach to future movies based on DC Comics characters and to seek a different — and perhaps younger?

Geomorphic process modeling allows us to evaluate different methods for estimating moraine ages from cosmogenic exposure dates, and may provide a means to identify the processes responsible for the excess scatter among exposure dates on individual moraines. Cosmogenic exposure dating is an elegant method for estimating the ages of moraines, but individual exposure dates are sometimes biased by geomorphic processes.
Because exposure dates may be either “too young” or “too old,” there are a variety of methods for estimating the ages of moraines from exposure dates. In this paper, we present Monte Carlo-based models of moraine degradation and inheritance of cosmogenic nuclides, and we use the models to examine the effectiveness of these methods. The models estimate the statistical distributions of exposure dates that we would expect to obtain from single moraines, given reasonable geomorphic assumptions.
The model of moraine degradation is based on prior examples, but the inheritance model is novel. The statistical distributions of exposure dates from the moraine degradation model are skewed toward young values; in contrast, the statistical distributions of exposure dates from the inheritance model are skewed toward old values. Sensitivity analysis shows that this difference is robust for reasonable parameter choices. Thus, the skewness can help indicate whether a particular data set has problems with inheritance or moraine degradation.
Given representative distributions from these two models, we can determine which methods of estimating moraine ages are most successful in recovering the correct age for test cases where this value is known. The mean is a poor estimator of moraine age for data sets drawn from skewed parent distributions, and excluding outliers before calculating the mean does not improve this mismatch. The extreme estimators youngest date and oldest date perform well under specific circumstances, but fail in other cases.

European metal artifacts in assemblages from sites predating the physical presence of Europeans in Northern Iroquoia in present-day New York, USA and southern Ontario, Canada have been used as chronological markers for the mid-sixteenth century AD. In the Mohawk River Valley of New York, European metal artifacts at sites pre-dating the physical presence of Europeans have been used by archaeologists as a terminus post quem TPQ of to in regional chronologies.
This has been done under the assumption that these metals did not begin to circulate until after sustained European presence on the northern Atlantic coast beginning in Here we use Bayesian chronological modeling of a large set of radiocarbon dates to refine our understanding of early European metal circulation in the Mohawk River Valley. Our results indicate that European iron and cuprous metals arrived earlier than previously thought, by the beginning of the sixteenth century, and cannot be used as TPQs.
Together with recent Bayesian chronological analyses of radiocarbon dates from several sites in southern Ontario, these results add to our evolving understanding of intra-regional variation in Northern Iroquoia of sixteenth-century AD circulation and adoption of European goods.

It might be hard to imagine or remember, but there was once a time when going on a date with a stranger you met online was a strange concept—frowned upon, even. Today, however, millennials have led the charge on transforming the dating industry and making online dating universally accepted. If you continue to have doubts, consider that there are now over 1, dating apps or websites looking to draw single men and women to their product, and to match them with one another. Though matchmaking is one of the oldest industries in existence, online matchmaking is now having a moment of its own.
This article explores the business of dating: the market size of dating apps in the U. According to the Pew Research Center , between and , online dating usage has tripled among those between the ages of 18 and Beyond its existing users, dating services benefit from tailwinds such as an untapped market, increasing millennial spending power, young people delaying life milestones such as marriage and home purchasing, as well as working longer hours. This is all on top of the growing ubiquitousness of broadband internet and growing acceptance and legitimacy around online dating.
While few would be surprised to hear that young adults are active with online dating, they might be when they realize that those in their late 50s and 60s are also quite active.
Models is a book on becoming an attractive man based not on tricks, tactics, games or techniques, but on self-development. So I was more than pleasantly surprised to discover that Models goes well beyond what he discusses on his blog. In my mind though, the most important aspect of this book is the mindsets and attitudes he advocates.

Maarten Blaauw and J. Radiocarbon dating is routinely used in paleoecology to build chronologies of lake and peat sediments, aiming at inferring a model that would relate the sediment depth with its age. We present a new approach for chronology building called “Bacon” that has received enthusiastic attention by paleoecologists. Our methodology is based on controlling core accumulation rates using a gamma autoregressive semiparametric model with an arbitrary number of subdivisions along the sediment.
Using prior knowledge about accumulation rates is crucial and informative priors are routinely used. Since many sediment cores are currently analyzed, using different data sets and prior distributions, a robust adaptive MCMC is very useful. We use the t-walk Christen and Fox, , a self adjusting, robust MCMC sampling algorithm, that works acceptably well in many situations.
Outliers are also addressed using a recent approach that considers a Student- t model for radiocarbon data.
