Knowledge, Attitudes, And Practice Towards Epilepsy: Survey Of Chinese And Vietnamese College Students In The U.S.

We conducted the first national cross-sectional survey of chinese and Vietnamese American adults about their knowledge, attitudes, and practice towards epilepsy. We used a convenience sampling method to recruit 2,831 adults in 37 cities from 7 states. In this article, we present our results from the analysis of a subset of the college student population. A 34-item survey instrument available in English, chinese (Mandarin and cantonese), and Vietnamese was administered by trained surveyors to 371 college students in 4 states. chinese and Vietnamese college students generally held the same attitudes towards and had similar misunderstandings about epilepsy. one notable disparity in attitudes is that 15% of chinese, as compared to 40% of Vietnamese, felt that PWE have below-average intelligence. We found that misunderstandings about and discrimination towards epilepsy among college students generally did not differ between different genders or ethnicities.

Associations among Plankton Abundance, Water Quality And Sediment Quality In The San Francisco Bay: Nitrogen And Phosphorus

nutrients from anthropogenic pollution can degrade water quality and alter the balance of marine food webs. lying at the base of the trophic pyramid, plankton quickly respond to nutrient changes in the water, which can have repercussions throughout both pelagic and benthic food webs, and thus they serve as a good bioindicator of water quality. In early november 2009, we evaluated sediment pollution, water pollution, and plankton abundance at four shoreline sites in the San Francisco Bay. We tested the sediment for nitrogen, phosphorus, potassium, and pH levels, all factors that can affect growth of primary producers. In the water, we tested nitrate, phosphate, and pH levels. lastly, we sampled shoreline plankton abundance both morning and evening. Sediment phosphorus and water phosphates were strongly correlated with one another, but water nitrates remained relatively constant, at low levels, across sites. daytime plankton abundance showed a positive trend with water phosphate. these trends suggest nitrogen is quickly taken up by plankton, making nitrogen the limiting factor for them. the relationship between plankton and phosphorus is influenced by more complex factors.
