PDF Ebook Dietary Supplements: Ephedra

Submitted by antoq on Wed, 07/08/2009 - 02:09

Ephedrine is a natural constituent of the herb ephedra and a synthetic compound present in certain over-the-counter drug products. The herbal form, known as Ma Huang in China, has been used as a remedy for asthma. In western cultures, ephedrine, the active drug product ingredient, has been used as a bronchodilator and decongestant for various respiratory problems. More recently, dietary supplements containing ephedra have been promoted for weight reduction and as a performance enhancer in body building and other sports.

Under the provisions of the Dietary Supplement Health and Education Act of 1994 (DSHEA), the Food and Drug Administration (FDA) must show that a supplement is unsafe and causes harm before it can be removed from the market. In 1997, following several hundred reports of adverse effects alleged to be caused by ephedra use, FDA proposed rules to restrict the dosage, require specific warnings on ephedra-containing supplements, prohibit supplements containing ephedrine combined with other known stimulants, and require warnings against excessive intakes. This proposal was criticized for the lack of scientific evidence to support FDA’s dosage limitations and the labeling requirements. In 2000, FDA withdrew part of the proposed rule, but subsequent highprofile deaths attributed to ephedra led FDA to re-propose the original regulation in 2003. On December 30, 2003, the Department of Health and Human Services (HHS) and FDA announced plans to prohibit sale of ephedra, using the safety provisions of DSHEA for the first time.

Ebook Allocation of Prizes in Asymmetric All Pay Auctions

Submitted by puput on Tue, 05/03/2011 - 07:45

In all pay auctions each player submits a bid (effort) for the object being sold, the player who submits the highest bid receives the object, but, independently of success, all players bear the cost of their bids. Common applications of all pay auctions include rent seeking, lobbying in organizations, R&D races, political contests, promotions in labor markets, and sport competitions. In the economic literature, all pay auctions are usually studied under complete information where the playersfvaluations for the object are common knowledge (see, for example, Hillman and Samet (1987), Hillman and Riley (1989), Baye et al. (1993) and Che and Gale (1998)), or under incomplete information where each playerfs valuation for the object is private information to that player and only the distribution of the players valuations is common knowledge (see, for example, Hillman and Riley (1989), Amman and Leininger (1996), Gavious et al. (2003) and Moldovanu and Sela (2006)).

Ebook An Analysis of Small Business Patents by Industry and Firm Size

Submitted by puput on Tue, 08/18/2009 - 06:34

This report describes the key findings in a project to create a detailed database of 1,293 small and large technology firms. The firms were chosen because they have at least 15 patents in the last five years in total, more than 1 million patents. The database was then used to highlight differences between the patent activity of small and large firms and to test several hypotheses about emerging technologies and industries.

The project, “SBA3,” extended previous studies of small business patenting activities conducted by the authors for the U.S. Small Business Administration (SBA), Office of Advocacy. The first two studies, SBA1 and SBA2, established the existence of a cohort of independent, nonbankrupt, for-profit small firms with 15 or more patents over a five-year period. Because small firms often find patenting too expensive and difficult, and thus make little use of the patent system, few would even have guessed such firms exist. SBA1 and SBA2 were the first studies of small business patenting that were based on a large, rich, and well defined dataset that encompassed the universe of significant patenting companies, rather being based on a sampling of a specialized patent set, or on the results of a survey.
