Selected AbstractsSponge disease: a global threat?ENVIRONMENTAL MICROBIOLOGY, Issue 6 2007Nicole S. Webster Summary Sponges are the most simple and primitive metazoans, yet they have various biological and ecological properties that make them an influential component of coral-reef ecosystems. Marine sponges provide refuge for many small invertebrates and are critical to benthic-pelagic coupling across a wide range of habitats. Reports of sponge disease have increased dramatically in recent years with sponge populations decimated throughout the Mediterranean and Caribbean. Reports also suggest an increased prevalence of sponge disease in Papua New Guinea, the Great Barrier Reef and in the reefs of Cozumel, Mexico. These epidemics can have severe impacts on the survival of sponge populations, the ecology of the reef and the fate of associated marine invertebrates. Despite the ecological and commercial importance of sponges, the understanding of sponge disease is limited. There has generally been a failure to isolate and identify the causative agents of sponge disease, with only one case confirming Koch's postulates and identifying a novel Alphaproteobacteria strain as the primary pathogen. Other potential disease agents include fungi, viruses, cyanobacteria and bacterial strains within the Bacillus and Pseudomonas genera. There is some evidence for correlations between sponge disease and environmental factors such as climate change and urban/agricultural runoff. This review summarizes the occurrence of sponge disease, describes the syndromes identified thus far, explores potential linkages with environmental change and proposes a strategy for future research towards better management of sponge disease outbreaks.

Yet, for many countries, the past 50 years or so has been a halcyon period of economic growth and, in real terms, declining food prices. Apart from lower food prices, attributes of convenience, health, pleasure and more esoteric social elements such as animal welfare-friendliness and environmental sustainability are increasingly important to consumers in their food choices. With higher household incomes has come an increasingly segmented food market, as businesses seek to differentiate their products from competitors to earn a premium above the basic commodity price. In an increasingly competitive European and global market, whether the firm is small or large, the first step in successful product differentiation requires an insightful understanding of the drivers of consumer purchase and consumption behaviour. These have fundamental commercial importance in the marketing strategy of any business. Yet, a surprising number of businesses in the food and beverage industry know very little about who buys and consumes their products. In the 21st century, the primacy of consumers and citizens will be substantially more ,front and centre' than in the previous 50 years of production-driven agricultural and food policy. Les consommateurs européens font grise mine depuis qu'ils peinent à joindre les deux bouts dans un contexte de récession économique. Pourtant, dans de nombreux pays, les cinquante dernières années ont formé une période en or de croissance économique et de baisse des prix alimentaires en termes réels. Outre des prix plus bas, les consommateurs accordent, dans leurs choix alimentaires, une importance de plus en plus grande à des attributs en termes de commodité, de santé, de plaisir et d'éléments sociaux plus ésotériques comme le bon traitement des animaux et la durabilité environnementale. La hausse des revenus des ménages a entraîné une segmentation accrue des marchés des produits alimentaires car les entreprises cherchent à différencier leurs produits de ceux de leurs concurrents pour obtenir une prime en sus du prix du produit classique. Dans un marché européen et mondial de plus en plus concurrentiel, que l'entreprise soit petite ou grande, la première étape d'une différentiation de produit réussie consiste à bien comprendre les motivations des consommateurs en termes d'achat et leur comportement en terme de consommation. Ces considérations ont une importance commerciale primordiale dans la stratégie de commercialisation de toute entreprise. Pourtant, un nombre surprenant de firmes de l'industrie des aliments et boissons savent très peu de chose sur les clients qui achètent et consomment leurs produits. Au vingt-et-unième siècle, la primauté des consommateurs et des citoyens sera nettement plus ,,frontale et centrale" qu'elle ne l'était dans les cinquante dernières années durant lesquelles la politique agricole et alimentaire était axée sur la production. Gedrückte Stimmung hat sich unter den europäischen Verbrauchern breit gemacht, da sie in der Rezession über die Runden kommen müssen. Dabei konnten viele Länder in den vergangenen etwa 50 Jahren auf eine glückliche Zeit wirtschaftlichen Wachstums und real rückläufiger Lebensmittelpreise blicken. Einmal abgesehen von den geringeren Lebensmittelpreisen, richtet der Verbraucher sein Hauptaugenmerk bei der Auswahl seiner Lebensmittel zunehmend auf Kriterien wie Verbraucherfreundlichkeit, Gesundheit, Genuss sowie esoterischere soziale Elemente wie Tierschutzfreundlichkeit und Umweltverträglichkeit. Höhere Haushaltseinkommen führten zu einem immer stärker segmentierten Lebensmittelmarkt, da die Unternehmen danach streben, ihre Produkte von denen der Konkurrenz abzuheben, um einen Aufschlag auf den Grundwarenpreis zu erzielen. Ob es sich nun um ein kleines oder großes Unternehmen handelt: Auf einem zunehmend wettbewerbsorientierten europäischen Markt und Weltmarkt und auf dem Weg hin zu einer erfolgreichen Produktdifferenzierung ist es zunächst einmal erforderlich, die Triebfedern für die Kaufentscheidung und das Konsumverhalten des Verbrauchers zu verstehen. Diese spielen eine wichtige wirtschaftliche Rolle in der Marketingstrategie eines jeden Unternehmens. Dennoch wissen erstaunlich viele Unternehmen aus der Lebensmittel- und Getränkeindustrie nur sehr wenig darüber, wer ihre Produkte kauft und konsumiert. Im 21. Jahrhundert werden die Wünsche der Verbraucher und Bürger wesentlich stärker Vorrang haben als dies in den vergangenen 50 Jahren produktionsorientierter Agrar- und Lebensmittelpolitik der Fall war. [source] Larval transport and retention of the spiny lobster, Panulirus argus, in the coastal zone of the Florida Keys, USAFISHERIES OCEANOGRAPHY, Issue 5 2002Cynthia Yeung Abstract The spiny lobster Panulirus argus is of ecological and commercial importance in the South Florida coast of the continental USA and throughout the Intra-Americas Sea. Essential spiny lobster habitat in South Florida is primarily located in the Florida Keys coastal zone (including the Dry Tortugas), where the dynamic regional circulation coupled with the long planktonic larval duration (6,12 months) of P. argus raises questions of larval retention and recruitment. Locally spawned phyllosomata entrained in the Florida Current are likely to be expatriated out of the Straits of Florida, which implies that the local spiny lobster population is sustained by the transport of larval recruits from upstream locations. We examined the physical processes that may influence recruitment. Transport processes in the Keys coastal zone are spatially variable. Observed and modelled data suggest that the upper Keys is a point of onshore larval transport via the inshore meandering of the Florida Current, and the lower Keys to Dry Tortugas region apoint of retention through wind-driven onshore/countercurrents and eddy recirculation. Eddies that propagate between the Dry Tortugas and the lower Keys facilitate the exchange of larvae between the Florida Current and the coastal zone. Northerly wind events associated with cold fronts can enhance recirculation of larvae in the upper Keys. The association of older larvae with the Florida Current front supports the hypothesis that spiny lobster larval recruits come from upstream sources in the Caribbean. [source] Factors affecting secondary metabolite production in plants: volatile components and essential oilsFLAVOUR AND FRAGRANCE JOURNAL, Issue 4 2008A. Cristina Figueiredo Abstract The presence, yield and composition of secondary metabolites in plants, viz. the volatile components and those occurring in essential oils, can be affected in a number of ways, from their formation in the plant to their final isolation. Several of the factors of influence have been studied, in particular for commercially important crops, to optimize the cultivation conditions and time of harvest and to obtain higher yields of high-quality essential oils that fit market requirements. In addition to the commercial importance of the variability in yield and composition, the possible changes are also important when the essential oils and volatiles are used as chemotaxonomic tools. Knowledge of the factors that determine the chemical variability and yield for each species are thus very important. These include: (a) physiological variations; (b) environmental conditions; (c) geographic variations; (d) genetic factors and evolution; (e) political/social conditions; and also (f) amount of plant material/space and manual labour needs.

[source] Half a Century of Public Software Institutions: Open Source as a Solution to Hold-Up ProblemJOURNAL OF PUBLIC ECONOMIC THEORY, Issue 4 2010MICHAEL SCHWARZ We argue that the intrinsic inefficiency of proprietary software has historically created a space for alternative institutions that provide software as a public good. We discuss several sources of such inefficiency, focusing on one that has not been described in the literature: the underinvestment due to fear of hold-up. An inefficient hold-up occurs when a user of software must make complementary investments, when the return on such investments depends on future cooperation of the software vendor, and when contracting about a future relationship with the software vendor is not feasible. We also consider how the nature of the production function of software makes software cheaper to develop when the code is open to the end users. Our framework explains why open source dominates certain sectors of the software industry (e.g., programming languages), while being almost non existent in some other sectors (e.g., computer games). We then use our discussion of efficiency to examine the history of institutions for provision of public software from the early collaborative projects of the 1950s to the modern "open source" software institutions. We look at how such institutions have created a sustainable coalition for provision of software as a public good by organizing diverse individual incentives, both altruistic and profit-seeking, providing open source products of tremendous commercial importance, which have come to dominate certain segments of the software industry. [source] Detection of possible archaeological pathways in central Mexico through digital processing of remote sensing imagesARCHAEOLOGICAL PROSPECTION, Issue 2 2005Denisse Argote-Espino Abstract Many spaceborne multispectral images have been developed recently and applied in archaeology as they provide useful data, which can be digitized, manipulated and integrated. Principal component decomposition (PCD), texture segmentation and linear pattern detection through spatial filtering are useful techniques that provide a new way of processing satellite images in addition to traditional techniques. Such methods may supply more accurate information of an area, in particular a region of archaeological interest. In this paper we applied a new alternative method based on the techniques mentioned above to an important area of central Mexico. The region of study is located to the southwest of Las Cruces Range between the Mexico Basin and the Toluca Valley. Processing a multispectral image from that area, it was possible to detect possible communication corridors, which provided cultural and commercial linking to the ancient settlers of both adjacent basins. This information is very important for understanding the way these people interacted in the past and the commercial importance that could exist between them. Copyright © 2005 John Wiley & Sons, Ltd. [source] Development and characterization of three new diploid cell lines from Labeo rohita (Ham.)BIOTECHNOLOGY PROGRESS, Issue 4 2010Wazir S. Lakra Abstract Development of cell lines from fish for identifying the pathogenesis of viral diseases and for vaccine production against viral and bacterial diseases is imperative where they are of commercial importance. Three new diploid fish cell lines (RF, RH, and RSB) were developed from fin, heart, and swim bladder of an Indian major carp, Labeo rohita, commonly called Rohu. All the cell lines were optimally maintained at 28°C in Leibovitz-15 medium supplemented with 10% FBS. The propagation of RH and RSB cells was serum dependent, with a low plating efficiency (<16%), whereas RF cells showed 20% efficiency. The cytogenetic analysis revealed a diploid count of 50 chromosomes. The cells of RF and RSB were found to be epithelial, where as the cells of RH were mostly fibroblastic. The viability of the RF, RH, and RSB cell lines was 75, 70 and 72%, respectively after 6 months of storage in liquid nitrogen. The origin of the cell lines was confirmed by the amplification of 496 and 655 bp fragments of 16S rRNA and Cytochrome Oxidase Subunit I (COI) of mtDNA. The new cell lines would facilitate viral disease diagnosis and genomic studies. © 2010 American Institute of Chemical Engineers Biotechnol. Prog., 2010 [source] Developing the Concept of Transparency for Use in Supply RelationshipsBRITISH JOURNAL OF MANAGEMENT, Issue 4 2004Richard Lamming Management concern surrounding the supply of goods and services from business to business, and the related attempts to understand the phenomena observed therein, appears to rest upon a broad range of incompatible perspectives, from political science (often limited to considerations of power) to the logistical (akin to manipulation of a great, benign but dynamic jigsaw puzzle). It appears that all perspectives abrade against the difficulties of exchanging information, knowledge and innovation within the relationships between buying and selling organizations and the apparent chronic systemic inefficiency that transactions often represent in this context. This article addresses these concerns, exploring the concept of transparency and the developments necessary for it to be useful in exchanging sensitive information and tacit knowledge in supply relationships. Our central concern is how the understanding of transparency and its commercial importance may change when it is expressed as a manageable element of the relationship between two organizations rather than as a general property of a broader system (e.g. a supply network, industrial sub-sector, geographical cluster) and what utility this differentiation might hold for managers. The conclusion to the article, and the implication for managers, is that transparency might indeed be created and usefully managed within supply relationships but that it would differ fundamentally in meaning from previously posited concepts, with the same name, in different contexts.
