Steven Mailloux's 2021 Essay "Political Theologies of Sacred Rhetoric," and Walter J. Ong's Thought
No full textSee the above abstract.In my 4,000-word review essay "Steven Mailloux's 2021 Essay 'Political Theologies of Sacred Rhetoric,' and Walter J. Ong's Thought," I highlight certain points in Mailloux's perceptive essay in the new 290-page 2021 anthology Responding to the Sacred: An Inquiry into the Limits of Rhetoric, edited by Michael Bernard-Donals and Kyle Jensen (Penn State University Press, pages 77-98). For example, Mailloux discusses Pope Francis, the first Jesuit pope, and the Spanish Renaissance mystic St. Ignatius Loyola (1491-1556), the founder of the Jesuit order, and the author of the short book of instructions known as the Spiritual Exercises. In connection with highlights from Mailloux's fine essay, I discuss the thought of the American Jesuit Renaissance specialist and rhetorician Walter J. Ong (1912-2003; Ph.D. in English, Harvard University, 1955).N/AFarrell, Thomas. (2021). Steven Mailloux's 2021 Essay "Political Theologies of Sacred Rhetoric," and Walter J. Ong's Thought.

Reviewing the potential for behavioral guidance to improve downstream passage of out‐migrating anguillid eels
No full textHydroelectric dams and their turbine infrastructure threaten out-migrating anguillid eels en route to marine spawning grounds. For decades, invested parties have attempted to guide eels away from turbines and toward safe passage routes. A subset of this work (hereafter behavioral guidance) has involved exploiting sensory biology (e.g., sight and hearing) to divert eels from areas of danger toward safe passage, including collection facilities for trap and transport. Here, we narratively review these efforts and interpret available information through an applied lens. We collated relevant literature and organized it based on behavioral guidance modalities of light, sound, hydrodynamics, and electricity. Combined (multimodal) approaches were categorized under the primary behavioral stimulus. With further research, light could have some degree of potential as a standalone method, but field evidence indicates it is more practically effective when paired with physical barriers. Sound alone may not be sufficient, but flume evidence indicates it can also increase the effectiveness of physical barriers. Current evidence to support manipulation of hydrodynamics as a means to alter eel behavior is limited, and responses may vary considerably according to the nature of the manipulation. Electrical fields can be hazardous to downstream-swimming eels, though they generally do elicit behavioral effects. Given our current understanding, it is apparent that multimodal approaches, particularly light and sound to augment physical barriers, are likely the most realistic for achieving reliable and effective behavioral guidance. Future research could refine knowledge in this area. It is important to continue to scale promising methods to the field to assess practical relevance
Transport and connectivity modeling of larval permit from an observed spawning aggregation in the Dry Tortugas, Florida
No full textLarge aggregations of adult permit (Trachinotus falcatus) were consistently observed since 2004 by divers in a collaborative fishery-independent reef fish visual census survey during May and June on the western-most edge of the Dry Tortugas Bank, Florida, in coral reef habitat, indicating proximal spawning sites. We investigated the possible fate and connectivity of larvae spawned at this location in the Dry Tortugas and two other published aggregation sites through a drift analysis using the ocean circulation and transport dynamics simulator HYCOM (Hybrid Community Ocean Model). New age-length data facilitated the determination of larval durations and rates of juvenile growth. Modeled larval transport data from spawning sites in the Dry Tortugas, Belize and Cuba were evaluated and compared to a spatially-extensive empirical juvenile permit data set from Florida. Our study revealed that unique oceanographic processes provided pathways for both downstream larval transport and juvenile retention, to and from Florida waters. These simulation results indicated that the Dry Tortugas region is a key source of permit recruits to southeast Florida stretching from the Florida Keys and up Florida’s east coast, and to a much lesser extent the west Florida shelf. Simulations from Belize and Cuba spawning sites revealed high local retention with low connectivity to Florida, emphasizing the importance of local resource management throughout the permit’s range
Trends in shark bycatch research: current status and research needs
Get PDFOver the last few decades, much effort has been devoted towards quantifying and reducing bycatch in marine fisheries. Of late, there has been a particular focus on sharks given that bycatch is a frequently listed threat for sharks on the International Union for the Conservation of Nature Red List. However, currently there are no quantitative reviews or syntheses that explore the issue of shark bycatch globally which is problematic given that such a synthesis could inform conservation actions and identify pressing research gaps. We performed a qualitative and quantitative survey of the peer-reviewed literature to characterize trends in shark bycatch research with a particular goal of identifying research needs and opportunities. Using a structured literature review we identified 103 papers that met our search criteria, with the first one published in 1993. Early research efforts focused on documenting the scope of bycatch (i.e., determining that sharks were indeed captured as bycatch), but more recently there have been increased efforts devoted to developing and evaluating bycatch reduction strategies for sharks. Research activity was most common in the North Atlantic (~ 40% of the total articles analysed) with comparatively less research in other areas such as the Indo-Pacific region where shark bycatch is regarded as particularly common and problematic. Most studies were observational with comparatively fewer experimental and modeling studies, and even fewer that combined research approaches. Gear modifications (e.g., hook size and type for long lines, net size and mesh design for nets) were the most commonly evaluated strategy for reducing shark bycatch; however, development and use of techniques like repellents, or seasonal area closures, or a combination of strategies, offer interesting possibilities that require further study. In addition, although many sharks are discarded, little is known about post-release survival or sub-lethal consequences of fisheries interactions, or evaluations of different fish handling strategies, making it difficult to quantify the true cost of bycatch or to recommend handling strategies to fishers. Although there are some inherent challenges with developing and testing shark bycatch reduction strategies, there is an urgent need to do so and this would be best achieved through interdisciplinary research that spans field, laboratory, and modeling realms.Fil: Molina, Juan Manuel.
