Most infants form attachments to both of their parents at roughly the same age. These relationships are consolidated by continued interactions, ideally in a broad array of contexts, whether or not the parents live together. The mechanisms underlying the formation and consolidation of relationships with both parents appear to be similar, although most infants establish preferential relationship with the persons who take major responsibility for their care. When parents separate, children often experience distress, and their adjustment is adversely affected when the relationship with one of their parents is severed. This can be avoided by developing parenting plans that continue to ensure that children have regular interaction with both parents in a broad array of contexts. Overnight periods provide opportunities for many important interactions. 相似文献

Miniaturization of capillary electrophoresis onto a microchip for forensic short tandem repeat analysis is the initial step in the process of producing a fully integrated and automated analysis system. A prototype of the Berkeley microfabricated capillary array electrophoresis device was installed at the Virginia Department of Forensic Science for testing. Instrument performance was verified by PowerPlex 16 System profiling of single source, sensitivity series, mixture, and casework samples. Mock sexual assault samples were successfully analyzed using the PowerPlex Y System. Resolution was assessed using the TH01, CSF1PO, TPOX, and Amelogenin loci and demonstrated to be comparable with commercial systems along with the instrument precision. Successful replacement of the Hjerten capillary coating method with a dynamic coating polymer was performed. The accurate and rapid typing of forensic samples demonstrates the successful technology transfer of this device into a practitioner laboratory and its potential for advancing high-throughput forensic typing. 相似文献

Policies to protect Antarctic and Patagonian Toothfish in theSouthern Ocean are failing. Contests over sovereignty, the needfor international decisions to be approved by consensus, inabilityto physically patrol the Southern Ocean, and the political vacuumcreated by the designation of the high seas haveeach contributed to an overfishing crisis in the Southern Oceanand Antarctica. After documenting the contours of this fishingcrisis and explaining how international law is unable to preventit, this article proposes a fundamental shift in strategy awayfrom supply-side controls that require a presence in Antarcticawhere the overfishing occurs. Lawmakers must utilise more rigorousdemand-side measures if Toothfish stocks are to be preservedand allowed to recover. 相似文献
