Rifting transitions to full magmatic seafloor spreading in the wake of the propagating tip. The 25‐km‐long Hess Deep rift is the transitional segment from rifting to spreading. Intrarift ridge (IRR), located within Hess Deep rift, is interpreted as a detachment fault, which exhumes deep‐seated rocks to the seafloor. Although transitional segments must have occurred throughout the westward propagation of C‐N Rift, IRR is the only obvious detachment fault along the base of the Rift scarps in the last ~5 Ma of its propagation. IRR formation may be in response to a decrease in spreading rate (~40 to <20 mm/yr) and presumed lower melt supply, resulting from the formation of the Galapagos microplate ~1.4 Ma, which now controls the opening at the C‐N Rift tip.D.K.S. and H.S were supported in part by WHOI.2018-10-2

The definitive version was published in Oceanography 18, 1 (2005): 47-50, doi: 10.5670/oceanog.2005.70.In 1999 as the millennium was drawing to a close, we decided that the time was right to introduce a new type of web site highlighting the contributions that women are making to marine science. We envisioned a web site where women considering careers in oceanography could read about the experiences of successful women and learn from their choices; that would convey the excitement of groundbreaking research in oceanography and serve as a resource for teachers, scientists, and the general public; and that would celebrate a group of remarkable women and bring a human face to those working in marine science

"Cold turkey" works best for smoking cessation. PRACTICE CHANGER: Counsel patients who want to quit smoking that abrupt smoking cessation is more effective for long-term abstinence than taking a gradual approach. STRENGTH OF RECOMMENDATION: B: Based on one well-designed, randomized controlled trial

Tectonic structure of the Mid-Atlantic Ridge near 16°30′N

The definitive version was published in Geochemistry, Geophysics, Geosystems 17 (2016): 3993–4010, doi:10.1002/2016GC006514.The 16°30'N area of the Mid-Atlantic Ridge represents an area of present-day detachment faulting. Here we present shipboard bathymetric, magnetic and gravity data acquired up to 65 km from the ridge axis that reveal a varied tectonic history of this region. Magnetic data are used to calculate spreading rates and examine spreading rate variability along and across the axis. Bathymetric and gravity data are used to infer the crustal structure. A central magnetic anomaly 40% narrower than expected is observed along much of the study area. Misalignment between modern-day spreading center and magnetic anomalies indicates tectonic reorganization of the axis within the past 780 ka. Observed magnetic anomalies show a pattern of anomalous skewness consistent with rotation of magnetic vectors probably associated with detachment faulting. Relatively thin crust north of a small (∼7 km) nontransform offset coincides with a weakly magmatic spreading axis. In contrast, to the south a robust axial volcanic ridge is underlain by thicker crust. Variations in crustal structure perpendicular to the axis occur over tens of kilometers, indicating processes which occur over timescales of 1–2 Ma.National Science Foundation Grant Number: OCE-11556502017-04-2

B. F. Skinner's contributions to applied behavior analysis

Our paper reviews and analyzes B. F. Skinner's contributions to applied behavior analysis in order to assess his role as the field's originator and founder. We found, first, that his contributions fall into five categorizes: the style and content of his science, his interpretations of typical and atypical human behavior, the implications he drew from his science for application, his descriptions of possible applications, and his own applications to nonhuman and human behavior. Second, we found that he explicitly or implicitly addressed all seven dimensions of applied behavior analysis. These contributions and the dimensions notwithstanding, he neither incorporated the field's scientific (e.g., analytic) and social dimensions (e.g., applied) into any program of published research such that he was its originator, nor did he systematically integrate, advance, and promote the dimensions so to have been its founder. As the founder of behavior analysis, however, he was the father of applied behavior analysis

Hydroacoustic monitoring of oceanic spreading centers : past, present, and future

The definitive version was published in Oceanography 25, no. 1 (2012): 116–127, doi:10.5670/oceanog.2012.10.Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, yet these events go largely undetected in the deep ocean. Currently, the only means available to observe seafloor-spreading events in real time is via the remote detection of the seismicity generated during faulting or intrusion of magma into brittle oceanic crust. Hydrophones moored in the ocean provide an effective means for detecting these small-magnitude earthquakes, and the use of this technology during the last two decades has facilitated the real-time detection of mid-ocean ridge seafloor eruptions and confirmation of subseafloor microbial ecosystems. As technology evolves and mid-ocean ridge studies move into a new era, we anticipate an expanding network of seismo-acoustic sensors integrated into seafloor fiber-optic cabled observatories, satellite-telemetered surface buoys, and autonomous vehicle platforms.SOSUS studies discussed in this paper were supported by the NOAA Vents Program and during 2006–2009 by the National Science Foundation, Grant OCE-0623649

Acquisitions and Regulatory Arbitrage by Captive Finance Companies

Captive finance firms play an important role as financial intermediaries. Yet, they receive little attention in financial research. Recently, finance companies have grown by engaging in acquisition activities. Given their unique characteristics, finance companies may be more capable of extracting gains from acquisitions than other firms. We explain their advantages, and assess the market response and long-term valuation of finance companies that engage in acquisitions. Our results indicate that acquisitions by captive finance firms are wealth enhancing in the short term and the long term. However, the market reacts negatively when flexible captive financing firms acquire highly regulated depository institutions

Hydroacoustic monitoring of seafloor spreading and transform faulting in the equatorial Atlantic Ocean

P. Hydroacoustic monitoring of seafloor spreading and transform faulting in the equatorial Atlantic Ocean. Journal of Geophysical Research: Solid Earth, 127(7), (2022): e2022JB024008, https://doi.org/10.1029/2022JB024008.Seismicity along mid-ocean ridges and oceanic transform faults provides insights into the processes of crustal accretion and strike-slip deformation. In the equatorial Atlantic ocean, the slow-spreading Mid-Atlantic Ridge is offset by some of the longest-offset transform faults on Earth, which remain relatively poorly understood due to its remote location far from land-based teleseismic receivers. A catalog of T-phase events detected by an array of 10 autonomous hydrophones deployed between 2011 and 2015, extending from 20°N to 10°S is presented. The final catalog of 6,843 events has a magnitude of completeness of 3.3, compared to 4.4 for the International Seismic Center teleseismic catalog covering the same region, and allows investigation of the dual processes of crustal accretion and transform fault slip. The seismicity rate observed at asymmetric spreading segments (those hosting detachment faults) is significantly higher than that of symmetric spreading centers, and 74% of known hydrothermal vents along the equatorial Mid-Atlantic Ridge occur on asymmetric spreading segments. Aseismic patches are present on nearly all equatorial Atlantic transform faults, including on the Romanche transform where regional rotation and transpression could explain both bathymetric uplift and reduction in seismic activity. The observed patterns in seismicity provide insight into the thermal and mechanical structure of the ridge axis and associated transform faults, and potentially provide a method for investigating the distribution of hydrothermal vent systems.This research was supported by National Science Foundation Grants EAR-1062238, EAR-1062165, and OCE-1839727.
