Geographical distribution of yellowfin tuna and skipjack catches in the Eastern Pacific Ocean, by quarters of the year, 1963-1966
ENGLISH: Logbook records of tuna vessels fishing in the eastern Pacific Ocean were used to prepare charts showing the distribution of yellowfin and skipjack tuna catches by 1-degree area, by quarter of the year, and by gear for the years 1963-1966. Recent changes in the geographical distribution of yellowfin catches are illustrated. The size composition of the U. S. tuna fleet is given, and recent changes are discussed. SPANISH: Los registros de los cuadernos de bitácora de los barcos atuneros que pescan en el Océano Pacifico oriental, se emplearon para preparar los gráficos que indican la distribuci6n de las capturas de atún aleta amarilla y de barrilete por área de 1 grado, por trimestre del ano y por aparejo de pesca para los anos de 1963-1966. Se ilustran los cambios recientes en la distribucion geográfica de las capturas de atún aleta amarilla. Se da la composición de tamaño de la flota atunera de los E. U. y se discuten los cambios recientes.

Geographical catch distribution of yellowfin and skipjack tuna in the Eastern Pacific Ocean, 1967-1970, and fleet and total catch statistics, 1962-1970
ENGLISH: Logbook records of tuna vessels fishing in the eastern Pacific Ocean were used to prepare charts showing the distribution of yellowfin tuna and skipjack catches by i-degree area, by quarter of the year, and by gear, for the years 1967-1970. Recent changes in the geographical distribution of yellowfin catch are illustrated. Also given are annual catch statistics and the composition of the international tuna fishing fleets which operated in the Commission's Yellowfin Regulatory Area each year, 1962-1970. SPANISH: Los registros de los cuadernos de bitácora de los barcos pesqueros de atĂşn en el OcĂ©ano PacĂfico oriental se usaron para preparar gráficos que presentan para los años de 1967-1970, la distribuciĂłn de captura del atĂşn aleta amarilla y barrilete por área de 1 grado, trimestre del año y, por las artes. Se ilustran los recientes cambios en la distribuciĂłn geográfica de la captura del atĂşn aleta amarilla. Se presentan tambiĂ©n las estadĂsticas de captura anual y la composiciĂłn de la flota internacional de pesca, que explota cada año el Area Reglamentaria de la ComisiĂłn, 1962-1970.

Studies on the Reduction of Radon Plate-Out
The decay of common radioactive gases, such as radon, produces stable
isotopes by a sequence of daughter particles with varied half-lives. These
daughter particles are a significant source of gamma, neutron, and alpha
particle backgrounds that can mimic desired signals in dark matter and
neutrinoless double beta decay experiments. In the LUMINA Laboratory at
Southern Methodist University (SMU), studies of radon plate-out onto copper
samples are conducted using one of XIA's first five UltraLo 1800 alpha
counters. We present results from investigations into various mitigation
approaches. A custom-built copper holder (in either plastic or metal) has been
designed and produced to maximize the copper's exposure to 220Rn. The 220Rn
source is a collection of camping lantern mantles. We present the current
status of control and experimental methods for addressing radon exposure
levels.Comment: 4 pages, 1 figure, Conference Proceedings for Low Radioactivity

My Reputation Always Had More Fun Than Me: The Failure of eBay\u27s Feedback Model to Effectively Prevent Online Auction Fraud
Online auctions for goods are currently a popular and lucrative form of e-commerce, but present special problems of trust and fraud prevention, because most deals involve buyers and sellers who do not know each other and are separated by distance. Online auctions for goods have been largely unregulated by formal laws. For that reason, trust-building and fraud prevention have primarily been accomplished through creative private regulatory models implemented by the auction houses themselves. This Comment examines one popular model, a registration and feedback system pioneered by the leading online auction company, eBay. Under this system, a user builds a public online reputation over time by engaging in a number of transactions and receiving public feedback from his transaction partners. By checking a potential transaction partner\u27s feedback file, a user can theoretically receive information about that party\u27s honesty and trustworthiness, and make an informed decision about transacting with that person. However, as this Comment will show, the growth of the user community has rendered this community policing model increasingly unreliable and unable to prevent bad behavior, although the model still has some psychological benefits. Therefore, eBay cannot rely on feedback systems to reliably prevent fraud, and must implement other forms of regulation (some of which are discussed in this Comment) or face being externally regulated by government entities
LinkedIn: Key Principles and Best Practices for Online Networking & Advocacy by Nonprofit Organizations
This research investigated the question:
What are the key strategic principles and the best practices of using LinkedIn for online interactive engagement and networking that nonprofit advocacy organizations can utilize to bolster constituent activism in support of shared goals? The methodology included a comprehensive literature review as well as a series of formal and informal conversations with thought leaders and practitioners of online advocacy. Analysis of research data provided the basis for recommendations and considerations for nonprofit organizations contemplating LinkedIn’s potential value for advocacy and networking efforts. These principles, best practices, recommendations and considerations for using LinkedIn’s networking toolset establish a framework for nonprofits to assess LinkedIn. The author recommends that advocacy organizations consider LinkedIn’s capabilities in the context of their mission, goals, culture and constituents. Among the research findings is the conclusion that LinkedIn is an exceptional social media platform in a number of respects, including the comprehensive amount of data LinkedIn contains and the sophisticated tools LinkedIn provides to mine and refine that data. LinkedIn consequently enables advocacy organizations to map strategic relationships and to customize their interaction with various segments of their audience
Grand Jury Secrecy
When a leading state such as Illinois enacts reform legislation, an impact on the legislatures of other jurisdictions may be anticipated. Accordingly, a need exists for an examination of this legislation in the light of the common-law background of grand jury secrecy and for a further analysis of it in the face of the growing trend toward more liberalized discovery of grand jury minutes in other jurisdictions. It is the contention of the author that such an empirical study will demonstrate that this legislation adopted by Illinois is contrary to all modern judicial thinking and is, in fact, a retrogressive step toward a period long outdated; that it facilitates serious abuses inherent in granting to the prosecution sole control over the use of grand jury minutes; and that, by the very limitations it creates, a serious question is raised as to its constitutionality
COUNTRY-OF-ORIGIN LABELING OF BEEF PRODUCTS: U.S. CONSUMERS' PERCEPTIONS
In 2002, Chicago and Denver consumers were surveyed and participated in an experimental auction to elicit willingness to pay for country-of-origin labeling (COOL) of beef. Survey results indicate the majority of consumers (73%) were willing to pay an 11% and 24% premium for COOL of steak and hamburger, respectively. In the auction, consumers were willing to pay a 19% premium for steak labeled “"U.S.A. Guaranteed: Born and Raised in the U.S.”" Food-safety concerns, preferences for labeling source and origin information, a strong desire to support U.S. producers, and beliefs that U.S. beef was of higher quality were reasons consumers preferred COOL.Consumer/Household Economics,
