Choosing the best model in the presence of zero trade: a fish product analysis

The purpose of the paper is to test the hypothesis that food safety (chemical) standards act as barriers to international seafood imports. We use zero-accounting gravity models to test the hypothesis that food safety (chemical) standards act as barriers to international seafood imports. The chemical standards on which we focus include chloramphenicol required performance limit, oxytetracycline maximum residue limit, fluoro-quinolones maximum residue limit, and dichlorodiphenyltrichloroethane (DDT) pesticide residue limit. The study focuses on the three most important seafood markets: the European Union’s 15 members, Japan, and North America

Sir John Adams: his legacy to the world of particle accelerators

John Adams acquired an unrivalled reputation for his leading part in designing and constructing the Proton Synchrotron (PS) in CERN's early days. In 1968, and after several years heading a fusion laboratory in the UK, he came back to Geneva to pilot the Super Proton Synchrotron (SPS) project to approval and then to direct its construction. By the time of his early death in 1984 he had built the two flagship proton accelerators at CERN and, during the second of his terms as Director-General, he laid the groundwork for the proton-antiproton collider which led to the discovery of the intermediate vector boson. How did someone without any formal academic qualification achieve this? What was the magic behind his leadership? The speaker, who worked many years alongside him, will discuss these questions and speculate on how Sir John Adams might have viewed today's CERN.Comment: 29 pages, John Adams Memorial Lecture 2009, published with high-resolution figures as CERN Yellow Report http://cdsweb.cern.ch/record/133152

Onboard sampling and the rockfish and lingcod commerical passenger fishing vessel industry in Northern and Central California, January through December 1994

The Central California Marine Sport Fish Project has been collecting angler catch data on board Commercial Passenger Fishing Vessels (CPFVs) fishing for rockfish or lingcod since 1987. The program depends on the voluntary cooperation of CPFV owners and operators. This fourth report in a series presents data collected in 1994, refers to historical data from 1987 to 1993, and documents trends in species composition, angler effort, catch per unit effort (CPUE), and, for selected species, mean length and length frequency. Angler catches on board central and northern California CPFVs were sampled from 14 ports, ranging from Crescent City in the north to Port San Luis (Avila Beach) in the south. Technicians observed a total of 2053 anglers fishing on 237 CPFV trips. These observed anglers caught 24,731 fish of which samplers determined 22,615 were kept. Over 63% of these fish were caught at Monterey or Morro Bay area ports. Only 18 of the 53 species each comprised at least one percent of the catch. The top ten species in order of abundance were blue, yellowtail, rosy, chilipepper, canary, and black rockfishes, lingcod, and widow, starry and greenspotted rockfishes. Blue and yellowtail rockfishes together comprised approximately 44% of the observed catch. Overall, rockfishes represented 32 species or 60% of the 53 identified species. In general, 1994 data showed continued evidence of sustainability of the CPFV rockfish fishery with a few exceptions for some species in each port area sampled. We identified areas of concern for three nearshore species (black, blue, and brown rockfishes), three offshore species (bocaccio, chilipepper, and widow rockfish), and two wide-depth range species (canary and yelloweye rockfishes). Declining trends in CPAH in at least one port area were identified for each of these species except black and blue rockfishes, some of which may be related to natural variability in year class strength or stock movement. Mean length decreased in at least one port area for black, blue, brown, and canary rockfishes and chilipepper, although for black rockfish and chilipepper this was attributed to increased recruitment of juveniles. Positive trends identified included increased CPAH for black rockfish in the San Francisco and Monterey areas, for canary rockfish in the San Francisco area, and for brown rockfish in the Morro Bay area. Total northern and central California CPFV catch estimates, based on logbook data and adjusted by sampling data and compliance rates, indicated that port area-specific decreases have occurred since 1988 for yellowtail rockfish and lingcod (San Francisco), chilipepper (Monterey), and blue rockfish (Monterey and Morro Bay). The competing influences of the nearshore commercial hook-and-line fishery were apparent when comparing relative species composition to that of the CPFV fishery. Declines in CPAH in the CPFV fishery for some shallow water species, such as brown rockfish in the Bodega Bay area, may be related to increased commercial fishing effort. (98pp.

ECONOMIC DISCOVERY IN FEDERALLY SUPPORTED IRRIGATION DISTRICTS: A TRIBUTE TO WILLIAM E. MARTIN AND FRIENDS

Ex post evaluation of economic projections validates our shared understanding of economic methodology and methods. The recent economic history of Central Arizona Project (CAP) agriculture reveals the predictive power of economic reasoning and its policy impotence within a political environment intent on obtaining its share of federally allocated water. The financial inability and unwillingness of large irrigation districts to pay for CAP water under existing federal rules produced an urban tax- and rate-payer controlled CAP decades earlier than planned. Yet irrigation districts remain a large residual buyer of CAP water under new pricing and allocation rules. Unfortunately, water markets remain an underutilized and distrusted tool in the water development game.Resource /Energy Economics and Policy,

SOCIAL CAPITAL, TRUST, AND THE AGRIBUSINESS OF ECONOMICS

Economists, including agricultural economists, have a long history of recognizing the importance of the behavioral foundations in decision making while ignoring these observable human dimensions in their economic models. The economics of social capital and trust, two important human characteristics influencing decisions, have captured the attention of economists in recent years. Recent empirical work demonstrates that social capital and trust considerations are prevalent and economically significant, especially in business. Trust alters the terms of trade, generates decision flexibility, reduces transaction costs, and creates additional time resources for management.Institutional and Behavioral Economics,

The Dynamics of Intra-jurisdictional Relations in the Inuit Regions of the Canadian Arctic: An Institutionalist Perspective

One of the most exciting developments in Canadian federalism has been the emergence of Aboriginal self-governing regions. This paper constructs a theoretical framework for exploring the evolution of intra-jurisdictional relations in the self-governing Inuit regions of the Canadian Arctic. Intra-jurisdictional relations in these regions are characterized by a unique set of relationships between elected governments and organizations that represent the beneficiaries of land-claims agreements. Using the literature on historical institutionalism, we argue that the nature of Inuit intra-jurisdictional relations following the establishment of self-government can be explained by the institutional choices made prior to the signing of land-claims agreements and/or self-government agreements. To illustrate the potential of our framework for analysing Inuit intra-jurisdictional relations, we briefly examine the experiences of Nunavut, an Inuit-dominated region and the newest territory in the Canadian federation

Onboard sampling of the rockfish and lingcod commerical passenger fishing vessel industry in northern and central California, January through December 1995

The Central California Marine Sport Fish Project has been collecting angler catch data on board Commercial Passenger Fishing Vessels (CPFVs) fishing for rockfish or lingcod since 1987. The program depends on the voluntary cooperation of CPFV owners and operators. This fifth report in a series presents data collected in 1995, refers to historical data from 1987 to 1994, and documents trends in species composition, angler effort, catch per unit effort (CPUE), and, for selected species, mean length, and length frequency. Angler catches on board central and northern California CPFVs were sampled from 12 ports, ranging from Fort Bragg in the north to Port San Luis (Avila Beach) in the south. Technicians observed a total of 1829 anglers fishing on 218 CPFV trips. These observed anglers caught 26,197 fish of which samplers determined 22,888 were kept. Over 62% of these fish were caught at Monterey or Morro Bay area ports. Only 18 of 55 species comprised at least one percent of the catch. The top ten species in order of abundance were yellowtail, blue, olive, and rosy rockfishes, lingcod, and canary, widow, gopher, starry, and vermilion rockfishes. Blue and yellowtail rockfishes together comprised approximately 47% of the observed catch. Overall, rockfishes represented 35 species or 64% of the 55 identified species. By number, rockfishes comprised 91.9 % of the observed catch. All CPUE and length data collected since 1987 were partitioned into six location groups for each port area, based on a combination of location, bottom depth, and distance from the nearest port. This allowed examination of indicator trends without potential biases due to non-random trip selection or ontogenetic changes in depth distribution for certain rockfishes. Results indicate that the two primary species in the northern and central California CPFV fishery, blue and yellowtail rockfishes (accounting for 47% of all observed fish in 1995), are in reasonably good condition with no steady declines in either average catch per angler hour or mean length during the last 8 years. The primary species of concern are mainly shallow-water species impacted by a recently expanded commercial hook-and-line fishery or deep-water species (chilipepper and bocaccio) which are fished intensively by the commercial industry and have experienced recent statewide stock declines. Estimated total rockfish catch, adjusted by logbook compliance rates and on board sampling data, has declined significantly in all port areas since 1992. This is largely attributable to increased recreational fishing effort for salmon as well as coast-wide stock declines in several important commercially fished species. (112pp.

Hermetically sealable package for hybrid solid-state electronic devices and the like

A light-weight, inexpensively fabricated, hermetically sealable, repairable package for small electronic or electromechanical units, having multiple connections, is described. A molded ring frame of polyamide-imide plastic (Torlon) is attached along one edge to a base plate formed of a highly heat conducting material, such as aluminum or copper. Bores are placed through a base plate within the area of the edge surface of ring frame which result in an attachment of the ring frame to the base plate during molding. Electrical leads are molded into the ring frame. The leads are L-shaped gold-plated copper wires imbedded within widened portions of the side wall of the ring frame. Within the plastic ring frame wall the leads are bent (typically, though not necessarily at 90 deg) so that they project into the interior volume of the ring frame for connection to the solid state devices
