Online Dating & Relationships

One in ten Americans have used an online dating site or mobile dating app themselves, and many people now know someone else who uses online dating or who has found a spouse or long-term partner via online dating. General public attitudes towards online dating have become much more positive in recent years, and social networking sites are now playing a prominent role when it comes to navigating and documenting romantic relationships. These are among the key findings of a national survey of dating and relationships in the digital era, the first dedicated study of this subject by the Pew Research Center's Internet Project since 2005

“I\u27ll do whatever as long as you keep telling me that I’m important”: A case study illustrating the link between adolescent dating violence and sex trafficking victimization

Background: Approximately 10% of U.S. high school-attending youth are physically abused by a dating partner each year. Many sequelae of dating violence have been documented, but the dating violence literature is lacking information about commercial sexual exploitation as a possible outcome of an abusive dating relationship. Conversely, scholarship on sex trafficking victimization has documented that some girls are enticed into sex work by exploitative partners who initially pretend to be dating partners, but the research lacks specificity about why and how the girls become vulnerable to these destructive relationships. This case series chronicles the experiences of four women who were commercially sexually exploited in the U.S. as minors, identifies common themes cross their narratives, and organizes these themes into a proposed framework for understanding a possible pathway from safety to unsafe dating to sex trafficking victimization. Methods: We conducted in-depth qualitative interviews with four adult women who had firsthand experience as victims of domestic minor sex trafficking. Participants were recruited through an organization that serves sex trafficking survivors. A constructivist grounded approach was used for data analysis. Participants’ narratives are presented, as well as illustrative quotes that typify each of the primary themes identified. Results: There were six primary themes that emerged from the cases’ narratives. Factors that made girls vulnerable to entering into abusive dating relationships and subsequently to experiences as sex trafficked minors included: (1) feeling physically unattractive and unimportant; (2) lacking examples of healthy relationships; (3) experiencing sexual abuse that caused subsequent dissociation and emotional debilitation; (4) being flattered by romantic gestures early in an abusive dating relationship and becoming emotionally attached; (5) gaining confidence from dating someone with higher social status; and (6) experiencing short-term satisfaction from out-earning other sex workers. Secondary themes that merit further investigation included having conflicts with guardians, engaging in criminal behavior at the request of their dating partner, and developing substance dependence that made it difficult to exit sex work. Discussion: Findings support the conclusions that one pathway into commercial sexual exploitation for minors is via dating partners, and that some minors are motivated to engage in sex work out of devotion to their dating partners rather than fear of violent retribution. A proposed framework for understanding how youth become vulnerable to sexual exploitation by a dating partner includes pre-dating, early phase dating, and late phase dating factors. Some pre-dating factors, for example, include feeling insecure, being bullied by peers, and having conflict with a guardian. Early phase dating factors include being impressed by the high social status of a new love interest and romantic gestures. Late phase dating factors include engaging in criminal activity to please the dating partner, and being physically, sexually, financially and emotionally abused. Additional empirical research that replicates and expands the proposed framework is encouraged, with the long-term objective of improving both dating violence and sexual exploitation prevention initiative

Should I Say Something? Dating and Sexual Aggression Bystander Intervention Among High School Youth

Using data from a sample of 218 high school youth from three high schools in New England (one rural, two urban), this brief discusses dating and sexual aggression bystander intervention among high school youth. Authors Katie Edwards, Robert Eckstein, and Kara Anne Rodenhizer-Stämpfli report that an overwhelming majority (93.6 percent) of high school students reported having the opportunity to intervene during the past year in situations of dating aggression or sexual aggression; however, in over one-third of the episodes (37.4 percent) students reported not intervening. Girls were more likely to intervene in situations of dating and sexual aggression than boys, and youth with histories of dating and sexual aggression were more likely to intervene than youth without these histories. Focus group data revealed that barriers to bystander intervention included avoidance of drama or a desire to fuel drama, social status and personal repercussions, closeness with the victim and/or perpetrator, the victim being male and the perpetrator female, the failure of the dating or sexual aggression to meet a certain threshold, the dating and sexual aggression occurring online, anticipated negative reactions from the perpetrator or victim, and an inability to relate to the situation. Given the mounting evidence that bystander education is a critical component of dat­ing and sexual aggression prevention, the authors urge policy makers and educators to enhance the presence of this type of education in high school health curricula and related course curricula

When did the 2001 recession really start?

The paper develops a non-parametric, non-stationary framework for business-cycle dating based on an innovative statistical methodology known as Adaptive Weights Smoothing (AWS). The methodology is used both for the study of the individual macroeconomic time series relevant to the dating of the business cycle as well as for the estimation of their joint dynamic. Since the business cycle is defined as the common dynamic of some set of macroeconomic indicators, its estimation depends fundamentally on the group of series monitored. We apply our dating approach to two sets of US economic indicators including the monthly series of industrial production, nonfarm payroll employment, real income, wholesale-retail trade and gross domestic product (GDP). We find evidence of a change in the methodology of the NBER’s Business-Cycle Dating Committee an extended set of five monthly macroeconomic indicators replaced in the dating of the last recession the set of indicators emphasized by the NBER’s Business- Cycle Dating Committee in recent decades. This change seems to seriously affect the continuity in the outcome of the dating of business cycle. Had the dating been done on the traditional set of indicators, the last recession would have lasted one year and a half longer. We find that, independent of the set of coincident indicators monitored, the last economic contraction began in November 2000, four months before the date of the NBER’s Business-Cycle Dating Committee.business cycle, non-parametric smoothing, non-stationarity

26Al/10Be Age of Peking Man

The chronological position of Peking Man, or Homo erectus pekinensis, has long been pursued, but has remained problematic due to lack of a suitable dating method^1-7^. Here we report cosmogenic ^26^Al/ ^10^Be burial dating of quartz sediments and artifacts from the lower strata of Zhoukoudian Locality 1 where the remains of early members of the Peking Man family were discovered. This study marks the first radioisotopic dating of any early hominin site in China beyond the range of mass spectrometric U-series dating. The weighted mean of six meaningful measurements, 0.75 +/-; 0.09 (0.11) Ma (million years), provides the best age estimate for lower cultural Layers ^7-10^. Together with previously reported U-series^3^ and paleomagnetic^4^ data, as well as sedimentological considerations^8, 9^ these layers may be further correlated to S6-S7 in Chinese loess stratigraphy or marine isotope stages 17-18, in the range of ~0.68-0.75 Ma. These ages are substantially older than previously supposed and may imply hominin presence in northern China throughout early Middle Pleistocene climate cycles

Connecting with tephras: principles, functioning, and applications of tephrochronology in Quaternary science

Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic, or archaeological sequences or events. The method relies firstly on stratigraphy and the law of superposition, which apply in any study that connects or correlates deposits from one place to another. Secondly, it relies on characterising and hence identifying or ‘fingerprinting’ tephra layers using either physical properties evident in the field or those obtained from laboratory analysis, including mineralogical examination by optical microscopy or geochemical analysis of glass shards or crystals (e.g., Fe-Ti oxides, ferromagnesian minerals) using the electron microprobe and other tools. Thirdly, the method is enhanced when a numerical age is obtained for a tephra layer by (1) radiometric methods such as radiocarbon, fission-track, U-series, or Ar/Ar dating, (2) incremental dating methods including dendrochronology or varved sediments or layering in ice cores, or (3) age-equivalent methods such as palaeomagnetism or correlation with marine oxygen isotope stages or palynostratigraphy. Once known, that age can be transferred from one site to the next using stratigraphic methods and by matching compositional characteristics, i.e., comparing ‘fingerprints’ from each layer. Used this way, tephrochronology is an age-equivalent dating method
