Interview with Frank R. Baumgartner, co-author, Suspect Citizens: What 20 Million Traffic Stops Tells Us About Policing and Race
No full textWe recently marked the 50th Anniversary of Terry vs. Ohio, the US Supreme Court case that dramatically expanded the scope under which agents of the state could stop people and search them. Taking advantage of a North Carolina law that required the collection of demographic data on those detained by the police during routine traffic stops, Frank Baumgartner and his colleagues analyzed twenty million such stops from 2002-2016. They present the results of this research in Suspect Citizens: What 20 Million Traffic Stops Tell Us about Policing and Race (Cambridge University Press, 2018). Join us as we speak with Baumgartner about what they found—and what we can do to reduce the most discriminatory features of the practice

Baumgartner ::a novel /
No full text"Paul Auster's brilliant eighteenth novel opens with a scorched pot of water, which Sy Baumgartner--phenomenologist, noted author, and soon-to-be retired philosophy professor--has just forgotten on the stove. Baumgartner's life had been defined by his deep, abiding love for his wife, Anna, who was killed in a swimming accident nine years earlier. Now 71, Baumgartner continues to struggle to live in her absence as the novel sinuously unfolds into spirals of memory and reminiscence, delineated in episodes spanning from 1968, when Sy and Anna meet as broke students working and writing in New York, through their passionate relationship over the next forty years, and back to Baumgartner's youth in Newark and his Polish-born father's life as a dress-shop owner and failed revolutionary. Rich with compassion, wit, and Auster's keen eye for beauty in the smallest, most transient details of ordinary life, Baumgartner asks: Why do we remember certain moments, and forget others?"-
Tectono-stratigraphic response of the Sandino Forearc Basin (N-Costa Rica and W-Nicaragua) to episodes of rough crust and oblique subduction
No full textThe southern Central American active margin is a world-class site where past and
present subduction processes have been extensively studied. Tectonic erosion/accretion
and oblique/orthogonal subduction are thought to alternate in space and time
along the Middle American Trench. These processes may cause various responses
in the upper plate, such as uplift/subsidence, deformation, and volcanic arc migration/
shut-off. We present an updated stratigraphic framework of the Late Cretaceous–
Cenozoic Sandino Forearc Basin (SFB) which provides evidence of
sedimentary response to tectonic events. Since its inception, the basin was predominantly
filled with deep-water volcaniclastic deposits. In contrast, shallow-water
deposits appeared episodically in the basin record and are considered as tectonic
event markers. The SFB stretches for about 300 km and varies in thickness from
5 km (southern part) to about 16 km (northern part). The drastic, along-basin, thickness
variation appears to be the result of (1) differential tectonic evolutions and (2)
differential rates of sediment supply. (1) The northern SFB did not experience major
tectonic events. In contrast, the reduced thickness of the southern SFB (5 km) is the
result of at least four uplift phases related to the collision/accretion of bathymetric
reliefs on the incoming plate: (i) the accretion of a buoyant oceanic plateau (Nicoya
Complex) during the middle Campanian; (ii) the collision of an oceanic plateau (?)
during the late Danian– Selandian; (iii) the collision/accretion of seamounts during
the late Eocene– early Oligocene; (iv) the collision of seamounts and ridges during
the Pliocene– Holocene. (2) The northwestward thickening of the SFB may have
been enhanced by high sediment supply in the Fonseca Gulf area which reflects
sourcing from wide, high relief drainage basins. In contrast, sedimentary input has
possibly been lower along the southern SFB, due to the proximity of the narrow,
lowland isthmus of southern Central America. Moreover, two phases of strongly
oblique subduction affected the margin, producing strike-slip faulting in the forearc
basin: (1) prior to the Farallon Plate breakup, an Oligocene transpressional phase
caused deformation and uplift of the basin depocenter, triggering shallowing-upward
of the Nicaraguan Isthmus in the central and northern SFB; (2) a Pleistocene– Holocene transtensional phase drives the NW-directed motion of a forearc sliverand reactivation of the graben-bounding faults of the late Neogene Nicaraguan
Depression. We discuss arguments in favour of a Pliocene development of the
Nicaraguan Depression and propose that the Nicaraguan Isthmus, which is the
apparent rift shoulder of the depression, represents a structure inherited from the Oligocene transpressional phase

Detailed mapping of the southern Pacific coast of Costa Rica, together with
stratigraphic, biostratigraphic, paleomagnetic studies, and preliminary geochemical
data, allowed to subdivide this region into four distinct tectonostratigraphic units: the
Golfito Terrane, the Burica Terrane, the Rincón Block and The Osa-Caño
Accretionary Complex. The paleomagnetic study extented to whole of Costa Rica
and western Panama, along with a compilation of new and old data , allowed to
define two more units: the Chorotega Terrane and the Nicoya Terrane, subdividing
the Central America isthmus into a total of six distinct units.
The Chorotega Terrane constitutes most of the southern Middle American
Landbridge and represent the western edge of the Caribbean Plate since the Late
Cretaceous. The other terranes have originated outboard in the Paleopacific and
were brought into contact with the Chorotega Terrane by plate convergence. They
are considered as exotic terranes. The Nicoya Terrane comprises the Santa Elena
Peninsula and most of the outer Nicoya Peninsula. The Nicoya Terrane includes the
Nicoya Complex (sensu stricto) and should therefore be regarded as a composite
terrane. The Golfito Terrane forms the Golfito region and extends into Panama to the
Azuero Peninsula. It is composed of a basaltic basement overlain by Upper
Cretaceous volcano-sedimentary series (Golfito Formation), in turn overlain by
volcaniclastic series (Quebrada Achiote Formation) recording the Paleocene
accretion of the terrane. The terrane is thought to have formed a marginal plateau of
the Caribbean plate, transported northward by strike-slip along the rim of the
Caribbean Plate. The Rincón Block forms the Osa peninsula isthmus. It is composed
of a thick pile of Late Cretaceous to Eocene oceanic basalts, and represents a piece
of island arc (Chorotega ?) tectonically incorporated to the collage of exotic terranes.
The Burica Terrane forms the Burica Peninsula. Late Cretaceous oceanic basalts
form the basement of the terrane, unconformably overlain by Paleocene sediments
partly derived from an intraoceanic platform mounted on an oceanic seamount. The
terrane is thought to represent an accreted, structurally high, portion of an
intraoceanic primitive island arc. The outer Osa Peninsula and the Caño Island are
part of the Osa-Caño Accretionary Complex, a mélange-type complex, characterised
by strongly deformed turbidites, hemipelagic and pelagic sediments. The complex
includes blocks of reworked shallow water Eocene limestones, as well as Late
Cretaceous to Miocene exotic blocks (basalts and associated pelagic sediments),
incorporated to the complex by offscraping of the subducting plate. Three units were
defined within the complex, which are the San Pedrillo Unit, the Cabo Matapalo Unit
and the Salsipuedes Unit.
The paleomagnetic data for the Chorotega Terrane indicate an origin close to its
present latitude and no significant rotation relative to South America since Late
Cretaceous time. The paleomagnetic data obtained from the Nicoya Terrane imply a
low southerly Late Cretaceous paleolatitude and almost no rotation relative to the
Chorotega Terrane. The Nicoya Terrane was about 16° of latitude south relative to
the Chorotega Terrane in Late Cretaceous times. The paleomagnetic data from the
Golfito Terrane indicate a Late Cretaceous equatorial paleolatitude and counter
clockwise rotation of about 60° relative to the Chorotega Terrane. Similar
paleomagnetic data were obtained from the Azuero Peninsula in southwestern
Panama. The paleomagnetic data from the Burica Terrane indicate a low northerly
latitude in the Paleocene and a counter clockwise rotation of nearly 90° relative to the
Chorotega Terrane
Demise of the Barra Honda Carbonate Shoal (Costa Rica) at the Paleocene‐Eocene Boundary Linked to Climate Change and Forearc Tectonics
No full textAbstract The latest Cretaceous(?)–Paleocene Barra Honda Formation represents one of the largest carbonate shoals (>900 km2, 350 m thick) of the convergent margin of Costa Rica. Although the mode of formation of the carbonate shoal is well understood, how environmental and tectonic factors interacted to cause its demise near the Paleocene‐Eocene boundary remains poorly constrained. Stable isotopic, biostratigraphic, mineralogical, and geochronological analyses from the Barra Honda Formation and overlying siliceous Buenavista Formation provide new constraints on the timing and causes of the demise of the carbonate shoal. We report one new U–Pb zircon chemical abrasion, isotope dilution, and thermal ionization mass spectrometry date (56.30 ± 0.13 Ma, 2σ) obtained from an ash‐rich layer at the boundary between the two formations. The sharp transition from Barra Honda massive limestones to Buenavista marl‐chert alternations coincides with a negative shift in carbon isotope (δ13Ccarb) values of about 3–5 ‰ and a 50% decrease in carbonate contents. The timing of the combined lithological‐mineralogical‐isotopic change is coeval with the Paleocene‐Eocene Thermal Maximum (PETM, 56 Ma). The onset of clay‐rich sedimentation is consistent with a PETM‐related increase in the terrestrial influx of nutrients and detrital particles, which promoted eutrophication and decreased light availability in the photic zone. Combined with seawater acidification and warming, these environmental parameters were fatal to the carbonate‐producing benthic communities of Barra Honda. High subsidence rates of the forearc basin and renewed arc volcanic activity must have closely followed the cessation of shallow carbonate production, preventing further formation of the carbonate shoal

Wilfrid Baumgartner
No full textLa trajectoire de Wilfrid Baumgartner tout au long du XXe siècle a été celle d'un financier, au double sens que le mot a hérité de l'Ancien Régime : technicien des choses de l'argent et serviteur de la chose publique. Inspecteur des Finances, directeur du Trésor, gouverneur de la Banque de France, ministre des Finances, président de Rhône-Poulenc, le cas Baumgartner éclaire pour la première fois à cette échelle biographique la figure du grand commis à la française, de la crise de la Ille République aux années sombres de Vichy, de l'instabilité politique de la IVE' République aux ruptures du régime gaulliste. Cette étonnante continuité de l'homme est aussi celle de l'État en France dans la période. Elle est analysée ici à travers les profondes mutations qu'a connues, des années 1920 aux années 1970, le système financier français (monnaie, Trésor, banques et crédit), tant du point de vue des modalités changeantes du financement de l'activité économique que de celui de la place et du rôle de la France dans le système monétaire international, notamment dans le contexte de la construction européenne. Une hypothèse à visée globale sous-tend cette traversée de l'histoire de la France contemporaine : celle de l'institution par étapes, flux et reflux, d'une économie d'endettement en France, clef d'un certain modèle économique (et social) qui aura marqué en profondeur le siècle passé. « Un homme d'État... Non ! Un homme de l'État. Cette formule de l'auteur, bien venue, situe tout à la fois la personnalité de Baumgartner et son aura, avec les questions originales qu'elles nous posent » Jean-Noël Jeanneney.Wilfrid Baumgartner’s path throughout the 20th century was one of a financier, in both senses of the word inherited from the Ancien Régime: monetary technician and public monies servant. Baumgartner’s career covered Inspector of Finance, Head of the Treasury Department, Governor of the Banque de France, Minister of Finance and Managing Director of Rhône-Poulenc. This biographical angle is a first in its exploration of the figure of senior French official from the crisis of the Third Republic to the dark Vichy years, from the political instability of the Fourth Republic to the fractures of the de Gaulle regime. This man’s surprising continuity is also the continuity of the State in France over this period. It is analysed here in terms of the huge changes made to the French financial system (currency, treasury department, banks and credit) from the 1920s to the 1970s, as much from the point of view of changing the ways of financing economic activity as France’s place and role in the international monetary system, especially with respect to European construction. One overarching hypothesis lies behind this journey through the history of modern France: that of the step-by-step, ebb-and-flow creation of a credit-based economy in France as the cornerstone of a certain economic (and social) model that made a huge mark on the last century. As Jean-Noël Jeanneney writes, “A statesman, no! A man of the State. This welcome wording by the author sums up Baumgartner’s personality and aura, with the original questions they raised.”La trayectoria de Wilfrid Baumgartner a lo largo del s. XX fue la de un financiero en el doble sentido que el término francés heredó del Antiguo Régimen: técnico en asuntos de dinero y servidor de la res publica. Inspector de Finanzas, director del Tesoro, gobernador de Banque de France, ministro de Finanzas y presidente de Rhône-Poulenc, el caso Baumgartner ilustra por vez primera a escala biográfica la figura del alto funcionario a la francesa, de la crisis de la III República a los oscuros años de Vichy, de la inestabilidad política de la IV República a las rupturas del régimen gaullista. Esta asombrosa continuidad del hombre es también la del Estado en Francia durante el mismo periodo. Una continuidad analizada aquí a través de los profundos cambios experimentados, desde la década de 1920 a los años 70, por el sistema financiero francés (moneda, Tesoro, banca y crédito), desde el punto de vista tanto de las cambiantes modalidades de financiación de la actividad económica como del lugar y el papel de Francia en el sistema monetario internacional, principalmente en el contexto de la construcción europea. Bajo este repaso de la historia francesa contemporánea subyace una hipótesis de calado global: la de la institución por etapas, flujo y reflujo, de una economía de deuda en Francia, clave de un cierto modelo económico (y social) que habría de dejar una profunda huella en el siglo pasado. “¿Un hombre de estado? No: un hombre del Estado.” La fórmula utilizada por el autor, muy acertada, sitúa al mismo tiempo la figura de Baumgartner y su aura con las cuestiones originales que nos plantean” (Jean-Noël Jeanneney).Le Comité pour l’histoire économique et financière est présidé par le ministre de l’Économie, des Finances et de l’Industrie, son vice-président est Maurice Lévy-Leboyer. a.

Derrière ces chiffres, il y a toute la vie de l’État d’une part, toute l’activité de la Nation de l’autre. » Wilfrid Baumgartner Cours de finances publiques, 1938-1939
