Strategies for commercialization of cryopreserved fish semen
No full textInitial success in sperm cryopreservation occurred at about the same time for aquatic species and livestock. However, in the 50 plus years since then cryopreserved sperm of livestock has grown into a billion-dollar global industry, while cryopreserved sperm of aquatic species remains a research activity with little commercial application despite work in more than 90 species and more than 200 published reports. Most research work has focused on large-bodied culture and sport fishes, such as salmon, trout, carp, and catfish, and mollusks such as commercially important oyster and abalone species. However, only a few studies have addressed sperm cryopreservation in small fishes such as zebrafish, or in endangered species. Overall, this work has yielded techniques that are being applied with varied levels of success around the world. Barriers to expanded application include a diverse and widely distributed literature base, technical problems, small sperm volumes, variable results, a general lack of access to the technology, and most importantly, a lack of standardization in practices and reporting. The benefits of cryopreservation include at least five levels of improvements for existing industries and for creation of new industries. First, cryopreservation can be used to improve existing hatchery operations by providing sperm on demand and simplifying the timing of induced spawning. Second, frozen sperm can enhance efficient use of facilities and create new opportunities in the hatchery by eliminating the need to maintain live males, potentially freeing resources for use with females and larvae. Third, valuable genetic lineages such as endangered species, research models or improved farmed strains can be protected by storage of frozen sperm. Fourth, cryopreservation opens the door for rapid genetic improvement. Frozen sperm can be used in breeding programs to create improved lines and shape the genetic resources available for aquaculture. Finally, cryopreserved sperm of aquatic species will at some point become an entirely new industry itself. A successful industry will require integrated practices for sample collection, refrigerated storage, freezing, thawing, rules for use and disposal, transfer agreements, and database development. Indeed the development of this new industry is constrained by factors including the technical requirements for scaling-up to commercial operations during the transition from research, and the absence of uniform quality control practices, industry standards, and appropriate biosecurity safeguards
Machine made: Irish America, Tammany Hall, and the creation of modern New York politics
No full textAlthough Tammany Hall was founded as a social club just after the American Revolution, it exists in memory as the quintessential American political machine, run by and for Irish-American political operatives more concerned with power than ideas. This dissertation seeks to re-interpret Tammany in the context of a transatlantic Irish experience of hunger, dislocation, and alienation. Irish immigrants brought with them distinct political narratives which were incorporated into Tammany Hall’s pragmatic but progressive ideology during the first quarter of the 20th Century. These political narratives, centered on the experience of powerlessness and oppression in Ireland and inextricably linked to Catholicism, led Irish immigrants to regard reformers in New York as American versions of their traditional enemies, the well-born Anglo-Protestant. The Irish arrived in New York with an understanding of the power of mass politics thanks to Daniel O’Connell’s campaign for Catholic Emancipation in the 1820s. Few studies of Tammany Hall attempt to link O’Connell’s mobilization of the Irish peasantry to Tammany’s ability to turn out the vote, especially after the Famine exodus of 1845-52. Likewise, the critical role of John Hughes, the first Catholic archbishop of New York and a native of Ireland, remains outside the story of Irish-American politics, despite the key role he played in organizing the Irish vote behind transatlantic grievances. This dissertation seeks to show how a particularly Irish experience in both Ireland and New York helped to mobilize a new kind of politics which emphasized cultural pluralism, populist rhetoric, and practical solutions to social injustice. A child of a Famine immigrant, Charles Francis Murphy, transformed Tammany into a force for social change during the Progressive Era. Murphy’s forgotten role in nurturing politicians such as Alfred E. Smith and Robert Wagner has been forgotten, but this dissertation will show that his embrace of change helped set the stage for the rise of Franklin Roosevelt and the implementation of the New Deal.Ph.

Willingness-to-Pay for Genetic Attributes in Aquaculture Industries
No full textThe genetic make-up of fish stocks is an important factor in aquaculture production. Choice-based conjoint analysis is used to determine importance of genetic improvements to grow-out producers and an estimated willingness-to-pay for selected attributes. Results from a national survey of aquaculture producers, reveal growth rate as the most important attribute.Resource /Energy Economics and Policy,

"Ut pictura movens poesis": Análisis transversal de la obra de Bill Viola y Terrence Malick
No full textThe work of the video artist Bill Viola and the film director Terrence Malick has not been interrelated thus far. But this research will prove that the significant parallelisms about the poetic treatment of the image, the conceptual basis and the philosophical background are not the result of a mere coincidence. Worries about topics conforming both author?s worlds of fantasy, as well as audiovisual sources, are in both cases entirely similar
Análisis de la pélicula El árbol de la vida, de Terrence Malick (2011)
No full textEl árbol de la vida es el quinto largometraje del director estadounidense Terrence Malick, estrenada en Cannes 2011. En este trabajo se analiza el carácter trascendente del film y su relación con el autor francés Robert Bresson, con el que comparte toda una serie de inquietudes y estilo. Además, se revisa la película desde una óptica cristiana, donde Malick nos muestra el origen del universo y el más allá, a la par que las relaciones interfamiliares de una familia tejana en los años 50. Asimismo, el film es una mirada íntima y catártica a la infancia y origen del propio director. De vocación poética, la película se sirve de una serie de recursos formales para conseguir su singular estética, en los que cabría destacar: la iluminación de Emmanuel Lubezki, el diseño de producción de Jack Fisk y el simbólico uso de la música unido a un preciso montaje. Palabras clave: Terrence Malick, El árbol de la vida, película, trascendente, poética.AbstractThe Tree of Life is the fifth feature film by the American director Terrence Malick, which was premiered at Cannes 2011. This work analyzes the transcendent nature of the film and the relationship between Malick and the French author Robert Bresson, with whom he shares a whole series of concerns and style. In addition, the film is reviewed from a Christian perspective, where Malick shows us the origin of the universe and the afterlife, as well as the inter-family relationships of a Texas family in the 1950s. Likewise, the film is an intimate and cathartic look to the childhood and origin of the director himself. With a poetic vocation, the film uses a series of formal resources to achieve its singular aesthetic, in which it is worth highlighting: the lighting by Emmanuel Lubezki, the production design by Jack Fisk and the symbolic use of music combined with a precise montage.Keywords: Terrence Malick, The tree of life, film, transcendent, poetic.<br /
Standardized Assessment of Thin‐film Vitrification for Aquatic Species
No full textUltrarapid cooling under the appropriate conditions will produce vitrification, a glass-like state used to cryopreserve small sample volumes, but there are a number of major technical drawbacks impeding the application of vitrification to germplasm of aquatic species. These include a lack of suitable devices, and poor reproducibility and comparability among studies due to a lack of standardization. We used 3-D printing to produce a viewing pedestal coupled with a classification system to rapidly assess frozen film quality of vitrification loops. Classification time declined with practice from 2.1 ± 0.3 sec (mean ± SD) to 1.5 ± 0.2 sec (after 200 assessments), and assessments were consistently made in \u3c 2.5 sec. Classifications should be reported with representative images allowing harmonization for quality control. This approach permits rapid classification and can be applied for the development of methods including the evaluation of vitrification solution components, concentrations of solutions and target cells, and configurations and volumes of new devices. Future studies should address the custom fabrication of 3-D printed vitrification devices for use with aquatic species and other applications
Environmental salinity-induced shifts in sperm motility activation in Fundulus grandis
No full textMotility activation of fish sperm typically responds to levels of specific ions or osmotic pressure differences between the surrounding water and body tissues. In general, the sperm of marine fishes are activated by an increase in osmotic pressure (hypertonic salinity), and that of freshwater species by a decrease (hypotonic salinity). These stenohaline species exist in relatively stable environments, however, estuarine fishes are exposed to rapidly changing and broad salinity ranges, often resulting in external osmotic pressures that include those of the body (isotonic). To assess the ability of Fundulus grandis sperm to adapt to changes in salinity, adult males were acclimated to salinities of 0, 5, 10, 20, 35, or 50ppt and held for 30d. The testes were dissected from the fish and sperm were activated with deionized water, various osmolalities (100-1000mOsmol/kg) of Hanks\u27 balanced salt solution (HBSS), calcium-free HBSS (Ca 2+-Free HBSS), and sodium chloride solution (NaCl). The deionized water did not activate sperm motility regardless of the acclimated salinity. Compared to HBSS, Ca 2+-Free HBSS and NaCl activated sperm motility with a significantly lower percentage at the same osmolalities. The osmolality eliciting the highest motility activation was significantly different (P\u3c0.01) among acclimated groups and shifted from 300mOsmol/kg (ranging from 200 to 500) for sperm collected from 5ppt, 500mOsmol/kg (ranging from 200 to 800) for sperm collected from 10ppt, 600mOsmol/kg (ranging from 400 to 700) for sperm collected from 20ppt, 800mOsmol/kg (ranging from 200 to 900) for sperm collected from 35ppt, and 900mOsmol/kg (ranging from 600 to 1000) for sperm collected from 50ppt. Motility peaked after 30s exposure to HBSS, and decreased over 10min. Motility exhibited a similar initial pattern when exposed to Ca 2+-Free HBSS, however, the sperm gained motility at lower osmolalities over 10min, exhibiting multiple peaks. These results indicate that environmental salinity can significantly influence sperm behavior in adult males of F. grandis with substantial changes after only 30d of acclimation. As such, this should be considered as a major unrecognized variable in sperm research in this species and can be considered for use in optimizing protocols addressing in-vitro fertilization and cryopreservation. Whether this phenomenon is unique to Fundulus or is a characteristic of euryhaline fishes remains unresolved. © 2011 Elsevier B.V
