Newswise — DETROIT — With nearly ninety percent of Americans utilizing the internet, the use of online dating websites has grown tremendously since the launch of the first online dating service in Today, Americans find it more culturally acceptable to look for a potential partner online and one-in-five adults between the ages of 25 to 34 have used online dating services. With the help of a 3. Stephanie Tong, Ph. She has been studying the association between romantic dating and computer-mediated communication, and with this grant, will explore the social implications of the rise of online dating. The project also will provide new insights regarding the ways that online dating systems are designed to facilitate interpersonal contact, impact the self-concepts of the people who use them, and it may provide new information and insights that can facilitate improvements to the design of popular forms of social computing technology. Although this project focuses on online dating systems, project findings may provide more generalizable insights regarding the complex interactions between communications media and the content of constitutions as well as their impact on communicators in many other contexts.

To support our nonprofit science journalism, please make a tax-deductible gift today. Geochronologists have tried to pinpoint the age of the million-year-old Deccan Traps, massive lava flows in India that may have helped wipe out the dinosaurs. But for too long, the arbiters of these stories—the geochronologists who date the age of rocks—have been underfunded and uncoordinated.
It could also calibrate, standardize, and improve the efficiency of different methods, which are based on the radioactive decay of elements within a rock. The consortium could help geochronology emerge from a deep slump, says Mark Harrison, a geochemist at the University of California UC , Los Angeles, who led a proposal cited in the new report.
Within the United States, the University of Arizona has pioneered Tandem Accelerator Mass Spectrometer (TAMS) radiocarbon dating. This technique is.
This technique is important to archaeologists and other scientists because it permits extremely small samples to be measured. Long’s laboratory is responsible for preparing samples for both the TAMS and conventional beta counting machines. With an additional three years of support, this laboratory will both continue its own research and provide a service function to the user community. It will pursue a series of specialized research projects. The laboratory has developed techniques for extracting and purifying organic components from bone.
Such samples have been shown to give reliable TAMS dates. This focus on bone work will continue. Emphasis will also be placed on dating early cultigens from North America to elucidate the prehistoric development of agriculture. Dating is crucial in archaeological research, and the development of TAMS technique has provided a major breakthrough because of relaxed sample size requirements. Many new questions could be addressed and many have been answered because of the Arizona work.
In the process it has become clear that a major problem lies in sample preparation; dates can be no better than the samples placed in the machine. Long’s laboratory has made and continues to make major strides in this area. This project is important because it provides a basic and necessary service not only to archaeologists but also to scientists working in a wide range of disciplines.

A Definitive List of Dating Acronyms You Need to Know
ABSTRACT Aggression between dating partners is a serious societal, health, and criminal justice problem that affects many persons, particularly adolescents and young adults. Although often understood as a phenomenon that is transmitted across generations, growing up in an aggressive household does not necessarily lead to aggressive romantic relationships. Identifying factors associated with resilience versus risk for young adult dating aggression is an important step for developing effective and targeted educational and intervention programs.
Much of the prior research focuses on static individual characteristics to identify who is at risk for dating aggression.

New research, however, has demonstrated that Chavin’s architectural sequence is much different and more complex than previously believed, and that its monumental construction concluded between – B. This represents a major shift in Chavin chronology that significantly impacts understanding of Andean formative social development. Chavin’s few dates are now associated with the final monumental stage and later periods of the site’s long construction sequence.
Consequently, the time depth represented by the undated, complex monumental stages prior to this suggests that the sequence extends much farther back in time than previously believed.
That could change if the National Science Foundation (NSF) funds a new consortium for geochronology—a major recommendation of a report.
NSF-funded technique may eventually allow scientists to better understand cycles of ice ages. This material is available primarily for archival purposes. Telephone numbers or other contact information may be out of date; please see current contact information at media contacts. A team of scientists, funded by the National Science Foundation NSF , has successfully used a new technique to confirm the age of a ,year-old sample of Antarctic ice. The new dating system is expected to allow scientists to identify ice that is much older, thereby reconstructing climate much farther back into Earth’s history and potentially leading to an understanding of the mechanisms that cause the planet to shift into and out of ice ages.
The new technique provides an accurate means of confirming the age of ice samples, and researchers note it is now the most precise dating tool for ancient ice. Department of Energy. Buizert, whose work also was supported in part by the National Oceanic and Atmospheric Administration, said reconstructing the Earth’s climate back to 1. The Earth is thought to have shifted in and out of ice ages every , years or so during the past , years, but there is evidence that such a shift took place every 40, years prior to that time.

Currently, Earth scientists have a difficult time placing narrow constraints on the precise time that a fault occurs deep within the crust of the Earth. This project combines two state-of-the-science techniques to directly date the time of faulting along a key fault zone in southeast Alaska, and thereby date when ancient earthquakes occurred. Development of this new analytical technique will enable considerable future research and understanding of how Earth materials deform. In addition, this research project will provide training and research opportunities for a female graduate student and several undergraduate students.
This project identifies artifacts and samples from recent excavations for radiocarbon dating and chronological modeling to understand the dates.
Arctic where the same site was occupied by multiple groups of people over time. This occupational history makes it easier to understand how past residents used the site and how those uses changed through time. The first excavation of Walakpa took place in , but much of the site remained unexplored. A few years ago, Walakpa began eroding into the sea due to rapid Arctic change, and urgent work to save the data began, resulting in data from two different excavations that need to be reconciled.
This project identifies artifacts and samples from recent excavations for radiocarbon dating and chronological modeling to understand the dates of these archaeological layers with better accuracy and precision, allowing archaeologists to link archaeological layers identified in with the more recent rescue excavations, allowing for a more complete picture of the archaeology of Walakpa.
New radiocarbon samples will be taken from well-provenienced samples from known Birnirk AD cultural levels and will be submitted for Accelerator Mass Spectrometry AMS radiocarbon dating and isotopic analysis. Bayesian chronological modeling of the Walakpa site radiocarbon data will be applied to produce realistic estimates for the dates of the site’s Birnirk presence.
This work will help establish a better regional chronology for Birnirk and the transition to the subsequent Thule AD period on the North Slope of Alaska.
What is a Worthless Check? They are commonly resolved in a small claims court civil suit. The proper judicial circuit for the prosecution of this crime is usually the circuit in which the check was presented and accepted. If you are the victim of passing a worthless bank check, contact the State Attorney for the judicial circuit in which the check was accepted and they will assist you in the recovery process. If you are the victim of a worthless check but the State Attorney cannot pursue the matter by prosecuting the crime, filing a civil suit in small claims court may be your best option.

AMS is an ultra-sensitive analytical technique for measuring low levels of long-lived radionuclides and rare trace elements. At Purdue we have constructed a major national AMS facility centered around the Physics Department’s tandem electrostatic accelerator. We are using the accelerator to measure both man-made and cosmic-ray-produced radionuclides such as 10 Be half-life 1,, years , 14 C years , and 36 Cl , years in natural samples having isotopic abundances down to one part in 1×10 15 a thousand million million.
Although the instruments and detection methods are those of nuclear physics, research applications are concentrated in the Earth sciences and biomedical sciences.

Dating sediments from Paleoindian sites : The chronology of the earliest human migrants to the New World is still disputed and unevenly documented. Radiocarbon dating from well stratified sites has been the traditional means of assessing this chronology, but radiocarbon in many cases can have problems with contamination or lack of association between dated and target events. Luminescence provides a complementary methodology in not only providing an independent means of dating but also allowing evaluation of stratigraphic integrity.
Luminescence dating of single grains has the potential to identify post-depositional mixing and other stratigraphic puzzles. Our laboratory routinely processes ceramics per year. We have tried to identify dating problems that are particularly suited to luminescence but difficult to resolve by other methods.
NSF pushed to boost funding for dating and squeezing rocks
Ask any girl, and they will tell you that dating an NSF recruit can be a total nightmare most of the time. Ask any guy who is about to enlist, they will tell you all the horror stories of girls breaking up with guys when they enlist. I mean come on la, these poor things are forced to serve the nation for 2 years, the least you could do is to be there for them right? Imagine having to wake up at 5am every morning, rush to get ready, chow down in 15 mins, attend lectures, spend more than half a day doing PT, drills, literally being the lowest life form in the Army everyday.

Earth science “decadal survey” also calls for study of near-surface geophysics. NSF pushed to boost funding for dating and squeezing rocks To answer questions about the planet’s future, earth scientists look to the past. But for too long, the arbiters of these stories—the geochronologists who date the age of rocks—have been underfunded and uncoordinated.
It could also calibrate, standardize, and improve the efficiency of different methods, which are based on the radioactive decay of elements within a rock.

Ever since the U. Geological Survey backed away from the field in the s, “We’ve been bootlegging innovation to routine analysis,” he says.
The geochronology funding could also help iron out discrepancies between labs and dating systems, says Dennis Kent, a paleogeographer at Rutgers University, New Brunswick, and study co-author.
