Review of \u3ci\u3eEmpires, Nations, and Families: A History of the North American West, 1800-1860\u3c/i\u3e by Anne F. Hyde

This extraordinary book is a recasting and retelling of virtually the entire history of the trans-Mississippi West from 1804 to about 1860. Its solid source foundation ranges from early fur-trade documents to the most recent monographs. It is amply illustrated with rarely seen visuals from many archives and replete with scores of real women and men-AngloAmerican, French, Native, and Metis. The focus is on family connections-marital, sexual, social, economic-and the crossing of racial boundaries and networks. Women are never absent, and their agency is evident. Every chapter opens with a vignette about a family member-man, woman, or child

Review of \u3ci\u3e Moving Stories: Migration and the American West, 1850-2000. \u3c/i\u3e Edited by Scott E. Casper and Lucinda M. Long

This well-written, well-illustrated anthology will gladden the hearts of students of the American West, not least because nine of the eleven authors are young-doctoral candidates or assistant professors. There is hope for Western studies. Five are historians, six trained in and teach literature, but most cross disciplinary boundaries quite easily. The geographical scope of the essays stretches well beyond the Great Plains, but the reader will land squarely between the Missouri and Montana in much of the volume. Theresa Strouth Gaul introduces the writings of three Pennsylvania sisters named Stewart who crossed the Overland Trail to Oregon in 1853 and their struggle (not always successful) to transcend the guidebook genre in describing their own migrant experiences. Linda Schelbitzki Pickle explains how gender shaped the recollections of Germans who journeyed to Iowa and Kansas between 1852 and 1905, particularly what male and female memoirists thought important to record and what not to. Gioia Woods discusses the life and writings of Sarah Winnemucca and how she worked to explain her Paiute world to a white audience. Matthew Evertson, focusing on Stephen Crane\u27s stories set in Nebraska and Mexico, shows how Crane devised a literary-realist vision of the West different from Theodore Roosevelt\u27s or Owen Wister\u27s. Douglas M. Edward provides a strongly documented description of boom-and-bust homesteading in Montana from 1908 to the early 1920s, revealing how both state-builders and homesteaders ... were motivated and ultimately betrayed by ideologies, ... the natural environment and global economic systems

Contribution of patient, physician, and environmental factors to demographic and health variation in colonoscopy follow-up for abnormal colorectal cancer screening test results

BACKGROUND: Patient, physician, and environmental factors were identified, and the authors examined the contribution of these factors to demographic and health variation in colonoscopy follow-up after a positive fecal occult blood test/fecal immunochemical test (FOBT/FIT) screening. METHODS: In total, 76,243 FOBT/FIT-positive patients were identified from 120 Veterans Health Administration (VHA) facilities between August 16, 2009 and March 20, 2011 and were followed for 6 months. Patient demographic (race/ethnicity, sex, age, marital status) and health characteristics (comorbidities), physician characteristics (training level, whether primary care provider) and behaviors (inappropriate FOBT/FIT screening), and environmental factors (geographic access, facility type) were identified from VHA administrative records. Patient behaviors (refusal, private sector colonoscopy use) were estimated with statistical text mining conducted on clinic notes, and follow-up predictors and adjusted rates were estimated using hierarchical logistic regression. RESULTS: Roughly 50% of individuals completed a colonoscopy at a VHA facility within 6 months. Age and comorbidity score were negatively associated with follow-up. Blacks were more likely to receive follow-up than whites. Environmental factors attenuated but did not fully account for these differences. Patient behaviors (refusal, private sector colonoscopy use) and physician behaviors (inappropriate screening) fully accounted for the small reverse race disparity and attenuated variation by age and comorbidity score. Patient behaviors (refusal and private sector colonoscopy use) contributed more to variation in follow-up rates than physician behaviors (inappropriate screening). CONCLUSIONS: In the VHA, blacks are more likely to receive colonoscopy follow-up for positive FOBT/FIT results than whites, and follow-up rates markedly decline with advancing age and comorbidity burden. Patient and physician behaviors explain race variation in follow-up rates and contribute to variation by age and comorbidity burden. Cancer 2017;123:3502-12. Published 2017.

PTF10nvg: An Outbursting Class I Protostar in the Pelican/North American Nebula

During a synoptic survey of the North American Nebula region, the Palomar Transient Factory (PTF) detected an optical outburst (dubbed PTF10nvg) associated with the previously unstudied flat or rising spectrum infrared source IRAS 20496+4354. The PTF R-band light curve reveals that PTF10nvg brightened by more than 5 mag during the current outburst, rising to a peak magnitude of R~13.5 in 2010 Sep. Follow-up observations indicate PTF10nvg has undergone a similar ~5 mag brightening in the K band, and possesses a rich emission-line spectrum, including numerous lines commonly assumed to trace mass accretion and outflows. Many of these lines are blueshifted by ~175 km/s from the North American Nebula's rest velocity, suggesting that PTF10nvg is driving an outflow. Optical spectra of PTF10nvg show several TiO/VO bandheads fully in emission, indicating the presence of an unusual amount of dense (> 10^10 cm^-3), warm (1500-4000 K) circumstellar material. Near-infrared spectra of PTF10nvg appear quite similar to a spectrum of McNeil's Nebula/V1647 Ori, a young star which has undergone several brightenings in recent decades, and 06297+1021W, a Class I protostar with a similarly rich near--infrared emission line spectrum. While further monitoring is required to fully understand this event, we conclude that the brightening of PTF10nvg is indicative of enhanced accretion and outflow in this Class-I-type protostellar object, similar to the behavior of V1647 Ori in 2004-2005.Comment: Accepted to the Astronomical Journal; 21 pages, 11 figures, 6 tables in emulateapj format; v2 fixes typo in abstract; v3 updates status to accepted, adjusts affiliations, adds acknowledgmen

On the Nature of the Progenitor of the Type Ia SN2011fe in M101

The explosion of a Type Ia supernova, SN 2011ef, in the nearby Pinwheel galaxy (M101 at 6.4 Mpc) provides an opportunity to study pre-explosion images and search for the progenitor, which should consist of a white dwarf (WD), possibly surrounded by an accretion disk, in orbit with another star. We report on our use of deep Chandra observations to limit the luminosity and temperature of the pre-explosion white dwarf (WD). It is found that if the spectrum was a blackbody, then WDs of highest possible temperatures and luminosities are excluded but, even if the WD was emitting at the Eddington luminosity, values of kT less than roughly 60 eV are permitted. This allows the progenitor to be an accreting nuclear-burning WD with an expanded photosphere. Pre-SN HST observations were used to derive a lower limit of about 10 eV for the expanded photosphere. Li et al.\, (2011) have already ruled out the possibility of a giant donor. We consider the combined emission from the WD, disk, and donor, and find that even the combined emission from a bright subgiant, WD and disk would not likely have been observed prior to explosion, and neither would some local candidates for the nuclear-burning WD model.Comment: 14 pages, 3 figures, 2 tables, submitted to ApJ Letter

Populism in world politics: a comparative cross-regional perspective

Populism has become more salient in multiple regions in the world, in developed as well as developing countries. Today it is largely a reaction to social dislocations tied to processes of neoliberal globalisation. As a concept, populism has had a long and contentious history. We suggest that populism has been on the rise alongside new imaginings of what constitutes the ‘people’ and ‘elites’, as the meanings attached to these labels are continually reshaped in conjunction with new social conflicts. These conflicts are intensifying across the globe together with new kinds of social marginalisation, precarious existence and disenchantment with the broken promises of liberal modernity. The article introduces a special issue on Populism in World Politics that seeks to understand general processes involved in the emergence of populist politics along with specific circumstances that affect how it is expressed in terms of identity politics, political strategies and shifting social bases

Heteroleptic actinocenes: a thorium(iv)-cyclobutadienyl-cyclooctatetraenyl-di-potassium-cyclooctatetraenyl complex.

From Europe PMC via Jisc Publications RouterHistory: ppub 2020-06-01, epub 2020-06-10Publication status: PublishedFunder: Engineering and Physical Sciences Research Council; Grant(s): EP/M027015/1, EP/P001386/1Despite the vast array of η n -carbocyclic C5-8 complexes reported for actinides, cyclobutadienyl (C4) remain exceedingly rare, being restricted to six uranium examples. Here, overcoming the inherent challenges of installing highly reducing C4-ligands onto actinides when using polar starting materials such as halides, we report that reaction of [Th(η8-C8H8)2] with [K2{C4(SiMe3)4}] gives [{Th(η4-C4[SiMe3]4)(μ-η8-C8H8)(μ-η2-C8H8)(K[C6H5Me]2)}2{K(C6H5Me)}{K}] (1), a new type of heteroleptic actinocene. Quantum chemical calculations suggest that the thorium ion engages in π- and δ-bonding to the η4-cyclobutadienyl and η8-cyclooctatetraenyl ligands, respectively. Furthermore, the coordination sphere of this bent thorocene analogue is supplemented by an η2-cyclooctatetraenyl interaction, which calculations suggest is composed of σ- and π-symmetry donations from in-plane in- and out-of-phase C[double bond, length as m-dash]C 2p-orbital combinations to vacant thorium 6d orbitals. The characterisation data are consistent with this being a metal-alkene-type interaction that is integral to the bent structure and stability of this complex

Market Collaboration: Finance, Culture, and Ethnography after Neoliberalism

In the wake of the disasters of March 2011, financial regulators and financial-risk management experts in Japan expressed little hope that much could be done nor did they take great interest in defining possible policy interventions. This curious response to regulatory crisis coincided with a new fascination with culturalist explanations of financial markets, on the one hand, and a resort to what I term “data politics”—a politics of intensified data collection—on the other. In this article, I analyze these developments as being exemplary of a new regulatory moment characterized by a loss of faith in both free market regulation and state-led planning, as well as in expert tools. I consider what might be the contribution of the anthropology of financial markets and ultimately argue for what I term a “collaborative economy” as a way to retool both financial and anthropological expertise
