Why Technology Provides Compelling Reasons To Apply A Daubert Analysis To The Legal Standard Of Care In Medical Malpractice Cases, Nichole Hines Nov 2006

Why Technology Provides Compelling Reasons To Apply A Daubert Analysis To The Legal Standard Of Care In Medical Malpractice Cases, Nichole Hines

Duke Law & Technology Review

Traditionally, courts have applied a "customary practice" standard in determining the legal standard of care in medical malpractice cases. Recently, a few courts have abandoned this dated standard and instead applied a Daubert analysis to the standard of care, which focuses on medical evidence that is scientifically based . In light of these recent holdings, this iBrief argues that with the increasing amounts of technologies improving evidence-based medicine, the customary practice standard is no longer a useful or appropriate test for determining the standard of care in medical malpractice cases. By applying a Daubert analysis to an expert’s testimony on …

Diapause In Aquatic Invertebrates:What's Known And What's Next In Research And Medical Application?, Victor R. Alekseev, Jiang-Shiou Hwang, Mei-Hui Tseng

Journal of Marine Science and Technology

Dormancy is a profound and ancient adaptation found in a wide spectrum of plants and animals of all habitats. In diapause the switch between active and dormant states is driven by hormonal mechanism that usually includes a photoperiodic pace-maker. Temperature, food limitation and some other stress factors as well are shown as driven by diapause induction in aquatic invertebrates. In the last decade, diapause studies from a wide variety of topics have demonstrated that diapause switch mechanisms may be developed to create novel applications in biotechnology. Resting eggs accumulated in the surface lake sediments represent a “bank” of zooplankton species …
