    Beschreibung: The degradation of natural fish habitat in the ocean implies lost economic benefits. These value losses often are not measured or anticipated fully, and therefore they are mainly ignored in decisions to develop the coast for industrial or residential purposes. In such circumstances, the ocean habitat and its associated ecosystem are treated as if they are worthless. Measures of actual or potential economic values generated by fisheries in commercial markets can be used to assess a conservative (lower-bound) value of ocean habitat. With this information, one can begin to compare the values of coastal developments to the values of foregone ocean habitat in order to help understand whether development would be justified economically. In this paper, we focus on the economic value associated with the harvesting of commercial fish stocks as a relevant case for the Saudi Arabian portion of the Red Sea. We describe first the conceptual basis behind supply-side approaches to economic valuation. Next we review the literature on the use of these methods for valuing ocean habitat. We provide an example based on recent research assessing the bioeconomic status of the traditional fisheries of the Red Sea in the Kingdom of Saudi Arabia (KSA). We estimate the economic value of ecosystem services provided by the KSA Red Sea coral reefs, finding that annual per-unit values supporting the traditional fisheries only are on the order of $7000/km2. Finally, we develop some recommendations for refining future applications of these methods to the Red Sea environment and for further research.

    Beschreibung: We investigate the effects of shoreline change and protective structures (seawalls) on home values, using data on residences sold between 2000 and 2010 in the coastal towns of Marshfield, Duxbury, and Plymouth, Massachusetts. These towns comprise shorelines that exhibit moderate rates of shoreline change, relative to other shorelines in the state, with extensive armoring. We investigate explicitly the effects of hard structural protection in combination with environmental amenities and hazards (distance to a beach, elevation of a property, location in a flood zone). We find that homeowners pay a premium in housing markets for nearshore properties protected by nature (higher elevations or more stable shorelines) or by humans (seawalls). The average marginal increase in nearshore property values associated with a 1m rise in elevation is 2 percent, a 1m (horizontal distance) decrease in the erosion rate is 0.2 percent, and location behind a seawall is 10 percent. The effects of erosion, elevation, and seawalls appear to be limited to properties located in close proximity to water or to oceanfront residences. Overall, the benefits of access to ocean amenities dominate the risks of exposures to hazards associated with shoreline change.

    Beschreibung: This report is a general, but comprehensive, description and analysis of industrial organization in the field of marine electronic instrumentation (MEl), a broadly defined "industry," which until now has received little systematic, scholarly attention. The report reviews the current literature on international trade and competitiveness, as well as trade and scientific journals relevant to the industry. The resul ts of a series of interviews with representatives of the industry and responsible government agencies are presented and industry and government data on R&D and output have been collected and analyzed together with other indicators of industrial performance. On the basis of these sources, the structure of the industry and its markets is characterized and the importance of marine electronic instrumenation in international high technology trade is established. Over 350 firms in the U.S. industry are identified, which annually earn total estimated gross revenues of approximately $5 billion. These firms fall into three largely distinct industry groups: (1) defense systems contractors; (2) commercial marine electronics; and (3) scientific instrumentation. The first group is by far the largest in sales volume and is oligopolistic in structure, consisting of a few large rivals for infrequent and complex defense systems contracts. The other groups are more purely competitive. Four major customer groups are distinguished: (1) military; (2) commercial and recreational shipping and boating; (3) offshore oil and gas; and (4) oceanographic/environmental. Most of the firms in the industry face international competititon. The importance of marine electronic instrumentation to technological advance and economic activity in the world's oceans is strongly apparent. Parameters affecting the international competitiveness of firms in this industry, including those relating to industry structure and behavior and governmental practices and institutions such as sponsored research, procurement, intellectual property rights, tax allowances, antitrust enforcement, small business encouragements, export controls, import restrictions, exchange rates, and technology transfer are summarized. A number of issues relating to international competititon, economic analysis, and government policy that are fruitful areas for further research also are identified.

    Beschreibung: Over the past five years, research on marine minerals conducted by the Marine Policy Center at the Woods Hole Oceanographic Institution has attempted to gain a better understanding of the process by which these minerals are brought into productive use in society. This technical report results from concentrated research conducted by a research team under the primary sponsorship of the National Sea Grant College Program. This report provides background documentation for the recent publication: J.M. Broadus, 1987, "Seabed Materials," Science 235(4791): 853-860. It is organized to lead the user directly to sources that may provide further information on particular seabed materials. Several presentations of data in the report are of use in understanding the fundamentals of marine mineral markets including: descriptions of the size of the marine mineral resource base and the size of the markets for onshore and offshore sources of marine minerals; price series for minerals with prospective seabed sources; composite prices for four marine mineral types; consumption and price "elasticities" of mineral reserves; trends in mineral exploration inputs and U.S. federal government expenditures for marine nonfuel resources; maps of existing, proposed, or past entitlements for marine hard minerals; a list of known marine polymetallic sulfide (MPS) deposits and reported grades; world trade flows in zinc and copper; the value of apparent consumption in the United States in relation to imports and recycling; and a bibliography.

    Beschreibung: Prior studies have shown that traders quickly converge to the price–quantity equilibrium in markets for goods that are immediately consumed, but they produce speculative price bubbles in resalable asset markets. We present a stock-flow model of durable assets in which the existing stock of assets is subject to depreciation and producers may produce additional units of the asset. In our laboratory experiments inexperienced consumers who can resell their units disregard the consumption value of the assets and compete vigorously with producers, depressing prices and production. Consumers who have first participated in experiments without resale learn to heed their consumption values and, when they are given the option to resell, trade at equilibrium prices. Reproducibility is therefore the most natural and most effective treatment for suppression of bubbles in asset market experiments.

    Beschreibung: Gold quantum dots exhibit distinctive optical and magnetic behaviors compared with larger gold nanoparticles. However, their unfavorable interaction with living systems and lack of stability in aqueous solvents has so far prevented their adoption in biology and medicine. Here, a simple synthetic pathway integrates gold quantum dots within a mesoporous silica shell, alongside larger gold nanoparticles within the shell’s central cavity. This “quantum rattle” structure is stable in aqueous solutions, does not elicit cell toxicity, preserves the attractive near-infrared photonics and paramagnetism of gold quantum dots, and enhances the drug-carrier performance of the silica shell. In vivo, the quantum rattles reduced tumor burden in a single course of photothermal therapy while coupling three complementary imaging modalities: near-infrared fluorescence, photoacoustic, and magnetic resonance imaging. The incorporation of gold within the quantum rattles significantly enhanced the drug-carrier performance of the silica shell. This innovative material design based on the mutually beneficial interaction of gold and silica introduces the use of gold quantum dots for imaging and therapeutic applications.
