From the Paper
"One of the common problems faced by historians, geologists, archaeologists and anthropologists is the estimation of the age of particular specimens. Historians are interested in such things as the age of the Dead Sea Scrolls. Anthropologists are interested in the age of jaw bones which were found at Olduvai Gorge in Tanganyika. Archaeologists are interested in the date of Ptolemy's sarcophagus. And geologists are interested in the age of the Earth. The answers for a long time evaded people. The best that geologists could do was come up with som sort of ordinal distinction: for example, they knew that the origin of the earth was an older event than the origin of the first rock and that the first rock was older than were the Rocky Mountains. Likewise, anthropologists could determine that Neanderthal man preceded Cro-Magnon, but still the exact age of these events ... "

Abstract
A paper which explains the beginning of radioactive dating - a process which can give scientists the age of rocks and other materials and help us to identify when Earth began. The paper explores the progression of this method and its uses today, as well as discusses different methods that are used, other than carbon-12, such as potassium or argon dating.
From the Paper
"Many view radioactivity as the end of the world in the event of a nuclear war. With its astonishing power, radioactivity could perhaps destroy and thus end the world. What many don't know about radioactivity is that is has the potential to tell scientists the age - or the beginning - of the Earth. Quite ironically, radioactivity could very well be responsible for both showing the beginning and the ending of Earth. A process called radiometric dating can give scientists the age of rocks and other materials and help us to identify when Earth began."

Abstract
Radioactive dating is the process of determining the age of rocks and other specimens from the decay of their radioactive elements. By applying this information, geologists are able to decipher the 4.6-billion-year history of the earth. The paper introduces the history of this type of dating in chronological order. It discusses other issues related to radioactive dating such as Carbon-14 dating, fission track dating, Potassium Argon Dating, the Rubidium-Strontium method, lead-alpha age and debated ideas of radioactive dating.
From the Paper
"Cosmic rays from the sun strike nitrogen 14 atoms in the earth?s atmosphere and cause nitrogen atoms to lose a proton making it a carbon isotope this then turns into radioactive carbon 14, which combines with oxygen to form radioactive carbon dioxide. All living things are in equilibrium with the atmosphere, and the radioactive carbon dioxide is absorbed from the air and used by green plants. Then the radioactive carbon dioxide gets passed on through the plants into the food chain and the carbon cycle. All living things contain a constant ratio of Carbon 14 to Carbon 12 of about 1 in a trillion. The amount of carbon 14 lost in a species is continually replenished as long as it still takes in food and oxygen. At death, the exchange of carbon 14 ceases and any that is left in the tissues of the organism begins to decay to Nitrogen 14, this is not replenished by any new C-14. The change in the Carbon 14 to Carbon 12 ratio is the basis for dating this dating technique. The half-life is so short (5730 years) that this method can only be used on materials less than 70,000 years old. A lot of archaeological dating uses this method. It is also very useful in attempting to date remnants of the ice ages (Pleistocene epoch.)"

Radiometric Methods of Dating Fossils, 2004.
An exploration of how carbon-14 and uranium-238 are used frequently in today?s scientific community to analyze the dates of fossils.

Abstract
This paper examines how both carbon-14 and uranium-238 are used to date fossils and how both methods are based on measuring the decay that has occurred in these elements. It looks at how carbon-14 dating is used for organic material, plants and animals, while uranium-238 is used primarily for geographic formations. It also discusses how both methods of dating are subject to potential sample contamination and, therefore, inaccurate readings; the addition of foreign material in both types of samples can provide either younger or older results, dependent on the material.
From the Paper
"Radioactive elements decay at unique rates, dependant on the isotope. This rate of decay is known as half-lives, it is the time necessary for ? of the atoms to decay in a particular element. The decay follows a geometric scale, in that in the first half-life of an element, ? of the atoms decay, yet in the second half-life, ? of those remaining decay, meaning a ? of the original atoms decay, and so forth. By measuring this decay, and knowing the half life of an element, scientists can date a sample."

Abstract
The paper introduces archaeology, and explains that the concept of dating is central to the science of archaeology. Two broad categories of dating, relative and absolute, are introduced, and four major specific types of dating are presented to the reader; stratigraphy, dendrochronology, obsidian hydration dating, and radiocarbon dating. Each of the four methods are discussed in great detail, each with a closing paragraph devoted to the underlying problems with that particular method. For example, the section on stratigraphy begins with a brief history of the method itself, and introduces such concepts as the law of superposition, temporal sequences of data within stratified deposits, context evaluation, and determining age through the relative position of superimposed artifacts. The negatives of stratigraphy are then discussed, and include deformation, overlapping and reverse stratigraphy, and the method is evaluated on the whole. This format is then applied to the other three types of dating discussed. Finally, a concluding paragraph states that although the four types of dating discussed are infinitely valuable to archaeologists all over the world, there are still problems associated with each that need to be accounted for when using them to address the age of fossilized remains and other artifacts.
From the Paper
"Archaeology is the study of past human cultures, and archaeologists must uncover and interpret material remains in order to reconstruct past ways of life. To understand the purposes of these remains, Archaeologists have the task of constructing a chronology of prehistory, using various dating methods. ?Without knowing the age of materials, little can be said about the activity that made them part of the site (David L. Webster, Susan Toby Evans & William T. Sanders, 1993: 128).? Dating is defined as the placement in time of events relative to one another or to any established scale of temporal measurement (Jeffrey S. Dean, 1981: 375). Dating methods used by Archaeologist incorporate the scientific method and have the advantages of objectification, application to isolated cultural sequences, and an expanded span of human prehistory for which an absolute chronology can be built (Keith Brannigan, 1974: 100-101). Scientific methods of dating are invaluable for the prehistoric periods and have revolutionized the archaeologists? ideas about the absolute chronology of the prehistoric culture sequence (Brannigan, 1974: 101), yet each of these scientific methods has many difficulties. Dating techniques fall into two categories?relative and absolute?and include the following: seriation, ceramic dating, potassium argon dating, thermoluminescence dating, archaeomagnetic dating, fission track dating, stratigraphy, dendrochronology, obsidian hydration dating, and radiocarbon dating. This paper will discuss the latter four methods, with an emphasis on the shortcomings of each."

Abstract
This paper examines aggressive sexual behavior as it occurs in dating situations among young adults. The author presents salient statistics showing how widespread this problem is. The paper further describes the combinations of interactions in which dating violence may happen. The paper discusses dating violence toward boys, as well as girls.
Outline:
Dating Violence and Its Prevalence
Dating and Dating Violence, Sexual in Nature
Men Upset more by Sexual infidelity; Women, by Emotional Infidelity
Young Women at a Greater Risk of Victimization
A Most Fatal Consequence: STDs
But Boys Get Victimized, Too
From the Paper
" There is a difference in the motivation for aggression between the genders. Evolutionary psychology has argued that men are more upset by their partner's sexual infidelity than women are but that women are more upset by their partner's emotional infidelity than are men (Forbes 2005). It identified jealousy as the proximal cause of relationship violence. It would, then, expect men to engage in more frequent and severe relationship violence in response to sexual infidelity than to emotional infidelity. In contract, women would resort to more frequent and severe relationship violence on account of emotional infidelity (Forbes et al)."

Abstract
This paper discusses the topic of dating in the United States and shows how technology has affected dating in the last 50 years. The paper shows the impact of technology during this period on dating patterns of "young adults", namely, those aged 13-30, depending on the social norm of the decade. Dating has always been a ritual by which young adults find themselves and discover their sexuality while trying out potential long-term mates. The paper explains that, today, dating has changed considerably due to advances in technology, such as films, MTV, and the Internet.
From the Paper
"The partners no longer need to be in the same room, car, or theater, they can be hundreds of miles away from each other and still date online. They can view films together, listen to the same music, and play games all over the Internet. They can chat whenever they want via Instant Messenger or email. The Internet has taken dating to another level, and has proved to be an excellent way for people to meet other people with the same interests and ideals."

Abstract
This study researches various reality television shows with themes of love and/or dating. The paper summarizes and analyzes various shows that each main network has aired. These networks include Paramount Domestic Television, Universal Worldwide Television, and Telepictures. It discusses how these networks used fame and exceptionally good-looking contestants to gain viewers. The paper discusses which shows have been popular and which have failed. It analyzes the use of stereotypes in dating reality shows and suggests why these shows are popular in American culture.
From the Paper
"Although shows which focus on a plot and script about love and dating have existed for decades, reality television has taken them to a whole new level which has recently become more popular and the focus of attention in American culture. Since the late nineties, the big networks such as ABC, NBC and CBS, as well as smaller or cable channels such as WB and MTV have scurried to broadcast their own love or dating based reality show that will be the next big hit among viewers. This genre of dating based reality television which was basically non-existent until recent television history now competes for the top slots in television ratings and sometimes earns them. Each channel has their own dating based reality show which they are best known for. By taking a look at each of these popular shows, one can get a better understanding of why love has become a particularly popular subject to focus on in reality television."

Abstract
In this article, the writer notes that the work-oriented culture of today's society has increased the prevalence of office romances. Long hours spent together at the workplace, exacerbated by the lack of time to spend on outside activities, often serve as a springboard for these types of relationships. However, the writer points out that with these relationships come certain liabilities for the associated employer. The writer discusses that forbidding fraternization between employees raises questions of discrimination as well as privacy issues. The writer then looks at the issue of possible no dating policies in the workplace. The writer concludes that the most moral solution would be one that is able to give employers protection against the risks they face with employee dating, while also allowing employees the freedom to live their lives outside the workplace.

Recommendation
From the Paper
"As noted earlier, there are significant downside risks for employers who have employees involved in inter-office relationships. Increased incidence of co-worker complaints of favoritism and the resultant negative effect on the team atmosphere and productivity coupled with possible reduced productivity from the employees involved are all significant concerns for an organization. In today's hyper-competitive, increasingly globalized world, these factors could significantly impact a company's bottom line with reduced competitiveness in their industry."
"In addition, allowing employee dating opens the organization up to an increased chance of sexual harassment lawsuits."

Online Dating, 2008.
This paper discusses how online dating has changed the nature of social interaction.
1,500 words (approx. 6.0 pages), 7 sources, APA, $ 49.95
»
Click here to show/hide summary
Abstract
In this article, the writer asserts that online dating has drastically changed the nature of social interaction in our modern society. Specifically, the writer notes that online dating has made it easier than in the past to lie about oneself, just as it has made it easier to find someone from someplace far away - albeit these kinds of relationships can bring their own problems. Proceeding further, the writer maintains that online dating has empowered socially dysfunctional types, has made the cultivation of traditional social skills less needed than in the past and it has brought young people into closer proximity with predators. All in all, the writer concludes that the Internet has brought many benefits to many people - but, like many innovations, its legacy is not a wholly happy one.
From the Paper
"One of the key impacts of technology - chiefly communication technology - in the last century has been that the world has been brought closer together. Television, the arrival of the mobile phone, the advent of the fax machine and, of course, the internet - all of these items have given people in different, remote geographic locations the ability to interact with others. In the particular case of online dating, the "pool" of potential mates is much larger than ever before. To wit, where once someone might be mostly confined to the local community when it came to seeking out a desirable partner, now an internet-savvy individual can, quite literally, scour the globe. Suffice it to say, this probably means, in the end, more "mixed" relationships between people of different races and ethnicities, and it also means more cross-cultural tensions; after all, different cultures have different expectations for men and women, and the clash between these opposing viewpoints can debilitate a fledgling marriage or partnership. Ultimately, new technologies - like online dating - gives people more options, but it also means they are confronted with challenges that their parents and grandparents really did not have to deal with."

Abstract
This paper reports that nonverbal communication is an important part of a dating relationship, in both nonsexual relationships and in the initiation of sexual behavior within relationships. The paper goes on to assert that, prior to escalating a relationship from a purely dating one, to one of a sexual nature, relationships must be assessed thoroughly, combining both verbal and nonverbal communication cues, for an optimum outcome.
From the Paper
"A positive sexual relationship between couples stems from successful communication regarding sexual and nonsexual preferences when intimate. In 1999, a study was conducted using men and women who were in dating relationships, but not dating each other. They were interviewed regarding sexual preferences and communication of their likes and dislikes. The research indicated that individuals are much more communicative about their sexual preferences when they are in a relationship in which communication was encouraged, not only about sex, but also about all aspects of the dating relationship. It was also determined that couples who have a nonverbal agreement and understanding about sex can be more effective and preferred over open discussion about sexual likes and dislikes."
