In Widowhood in an American City (1973), Helena Lopata observed that widows struggle with new romantic relationships because their children often are resentful toward these new partners. Since the publication of Lopata's classic work, however, few studies have explored empirically the ways that widow(er)'s dating affects their relationships with children. We use prospective data from the Changi...

Multiple studies have demonstrated that adolescent dating violence is highly prevalent and associated with internalizing and externalizing problems. A number of prevention initiatives are being implemented in North-American high schools. Such initiatives do not only aim to raise awareness among potential victims and offenders but also among peer bystanders. Since teenagers mainly reach out to t...

The Ilmeno-Vishnevogorsky miaskite-phenite-carbonatite complex (IVС), located in the Urals folded region, is a representative of "linear type" carbonatite complexes, with which Nb-Zr deposits are associated. ore potential linear time and duration ore-forming processes, geodynamic setting remain subject discussion. In order to estimate age formation processes IVC, U-Pb dating zircon (LA-ICP-MS) ...

The bauxite layer in Western Henan supplies a large number of ores and is useful for studying tectonic movement. In this paper, the samples were selected to carry out LA-ICP-MS detrital zircons U-Pb dating Hf isotope testing. results indicated that with Early Paleozoic ages mainly derived from North Qinling Orogenic Belt. Precambrian age may be basement China Block study support opinion Belt ha...

OBJECTIVE Dating violence is a significant health problem among youth that leads to adverse health outcomes, including injuries. Reciprocal violence (perpetrated by both partners) is associated with increased injury in adults, but very little is known about the prevalence and context for reciprocal violence, as well as injury rates, among youth. We sought to determine the prevalence and scope o...

Examinations of heavy drinking and dating violence have typically focused on either female victimization or male perpetration; yet recent findings indicate that mutual aggression is the most common pattern of dating violence. The current study investigated the relation between heavy drinking and dating violence for both men and women. Participants (N=2247) completed surveys that assessed their ...

Fault- and fracture-hosted multi-stage mineral assemblages that formed by fracture reactivation fluid migration, constitute archives of the tectonic evolution Precambrian cratons. Complex intergrowth patterns these records often hinder absolute dating mineralization events for geological models. We apply LA-ICP-MS/MS in situ Rb-Sr single crystal growth zones sub-mm-wide vein including illite, K...

Radiocarbon dating is one of the main methods used to establish peat chronologies. This article reviews the basis of the method and its application to dating of peat deposits. Important steps in the radiocarbon dating procedure are described, including selection and extraction of material (and fractions) for dating, chemical and physical preparation of media suitable for measurements, measureme...
