Abstract:

Marisa Palacios Knox, “‘The Valley of the Shadow of Books’: George Gissing, New Women, and Morbid Literary Detachment” (pp. 92-122) Victorian consternation about the physiological—especially reproductive—repercussions of women readers’ affective involvement with fiction is well documented. This essay contends, however, that at the fin de siècle a new cultural anxiety developed around the possibility of the woman who under-identifies, that is, refuses or is simply incapable of a stereotypically feminine standard of personal identification with literature. As the number of women entering vocational training as well as higher education increased exponentially in the late nineteenth century, the threat of women’s influx into the workplace expressed itself in a discourse of concern for the vitiation of women’s “natural” responsiveness to reading as a symptom of emotional as well as physical barrenness. George Gissing’s New Grub Street (1891) and The Odd Women (1893), in addition to the New Women novels of Charlotte Riddell and George Paston, engage with and complicate the idea of professional women’s literary detachment as a kind of morbid pathology, a trope that nevertheless continues to influence the reception of these works.

Abstract:

AbstractObservations were taken on an east-facing sidewall at the foot of a desert mountain that borders a large valley, as part of the Mountain Terrain Atmospheric Modeling and Observations (MATERHORN) field program at Dugway Proving Ground in Utah. A case study of nocturnal boundary layer development is presented for a night in mid-May when tethered-balloon measurements were taken to supplement other MATERHORN field measurements. The boundary layer development over the slope could be divided into three distinct phases during this night: 1) The evening transition from daytime upslope/up-valley winds to nighttime downslope winds was governed by the propagation of the shadow front. Because of the combination of complex topography at the site and the solar angle at this time of year, the shadow moved down the sidewall from approximately northwest to southeast, with the flow transition closely following the shadow front. 2) The flow transition was followed by a 3–4-h period of almost steady-state boundary layer conditions, with a shallow slope-parallel surface inversion and a pronounced downslope flow with a jet maximum located within the surface-based inversion. The shallow slope boundary layer was very sensitive to ambient flows, resulting in several small disturbances. 3) After approximately 2300 mountain standard time, the inversion that had formed over the adjacent valley repeatedly sloshed up the mountain sidewall, disturbing local downslope flows and causing rapid temperature drops.

Abstract:

An alternative technique for shadow detection and abundance is presented for high spatial resolution imagery acquired under clear sky conditions from airborne/spaceborne sensors. The method, termed Scattering Index (SI), uses Rayleigh scattering principles to create a diffuse skylight vector as a shadow reference. From linear algebra, the proportion of diffuse skylight in each image pixel provides a per pixel measure of shadow extent and abundance. We performed a comparative evaluation against two other methods, first valley detection thresholding (extent) and physics-based unmixing (extent and abundance). Overall accuracy and F-score measures are used to evaluate shadow extent on both Worldview-3 and ADS40 images captured over a common scene. Image subsets are selected to capture objects well documented as shadow detection anomalies, e.g., dark water bodies. Results showed improved accuracies and F-scores for shadow extent and qualitative evaluation of abundance show the method is invariant to scene and sensor characteristics. SI avoids shadow misclassifications by avoiding the use of pixel intensity and the associated limitations of binary thresholding. The method negates the need for complex sun-object-sensor corrections, it is simple to apply, and it is invariant to the exponential increase in scene complexity associated with higher-resolution imagery.

Abstract:

Synopsis Functional tradeoffs are often viewed as constraints on phenotypic evolution, but they can also facilitate evolution across the suboptimal valleys separating performance peaks. I explore this process by reviewing a previously published model of how disruptive selection from competing functional demands defines an intermediate performance optimum for morphological systems that cannot simultaneously be optimized for all of the functional roles they must play. Because of the inherent tradeoffs in such a system, its optimal morphology in any particular environmental context will usually be intermediate between the performance peaks of the competing functions. The proportional contribution of each functional demand can be estimated by maximum likelihood from empirically observed morphologies, including complex ones measured with multivariate geometric morphometrics, using this model. The resulting tradeoff weight can be mapped onto a phylogenetic tree to study how the performance optimum has shifted across a functional landscape circumscribed by the function-specific performance peaks. This model of tradeoff evolution is sharply different from one in which a multipeak Ornstein–Uhlenbeck (OU) model is applied to a set of morphologies and a phylogenetic tree to estimate how many separate performance optima exist. The multi-peak OU approach assumes that each branch is pushed toward one of two or more performance peaks that exist simultaneously and are separated by valleys of poor performance, whereas the model discussed here assumes that each branch tracks a single optimal performance peak that wanders through morphospace as the balance of functional demands shifts. That the movements of this net performance peak emerge from changing frequencies of selection events from opposing functional demands are illustrated using a series of computational simulations. These simulations show how functional tradeoffs can carry evolution across putative performance valleys: even though intermediate morphologies may not perform optimally for any one function, they may represent the optimal solution in any environment in which an organism experiences competing functional demands.

Abstract:

A handsome blond, Leon Patterson looked like a picture of the California dream; more than a few of us yearned to be him. He was, however, the product of the California reality: poverty, toil, and grit. His family had struggled west from Arkansas searching for opportunities in the shadow of the Great Depression. The Pattersons were part of the larger, second wave of “Okies, Arkies, and Texies” who migrated during the 1940s. The Great Central Valley, at 15,000,000 acres about the size of Egypt, held the promise of at least seasonal work, even for unskilled laborers—especially at its larger southern end, called the San Joaquin Valley by locals. By World War II, the Valley had become one of the state’s economic engines, sustained by agribusiness, oil, and abundant cheap labor.

Abstract:

Collecting comprehensive knowledge about spectral signals in areas composed by complex structured objects is a challenging task in remote sensing. In the case of vegetation, shadow effects on reflectance are especially difficult to determine. This work analyzes a larch forest stand (<i>Larix decidua</i> MILL.) in Pinnis Valley (Tyrol, Austria). The main goal is extracting the larch spectral signal on Landsat 8 (LS8) Operational Land Imager (OLI) images using ground measurements with the Cropscan Multispectral Radiometer with five bands (MSR5) simultaneously to satellite overpasses in summer 2015. First, the relationship between field spectrometer and OLI data on a cultivated grassland area next to the forest stand is investigated. Median ground measurements for each of the grassland parcels serve for calculation of the mean difference between the two sensors. Differences are used as “bias correction” for field spectrometer values. In the main step, spectral unmixing of the OLI images is applied to the larch forest, specifying the larch tree spectral signal based on corrected field spectrometer measurements of the larch understory. In order to determine larch tree and shadow fractions on OLI pixels, a representative 3D tree shape is used to construct a digital forest. Benefits of this approach are the computational savings compared to a radiative transfer modeling. Remaining shortcomings are the limited capability to consider exact tree shapes and nonlinear processes. Different methods to implement shadows are tested and spectral vegetation indices like the Normalized Difference Vegetation Index (NDVI) and Greenness Index (GI) can be computed even without considering shadows.

Abstract:

The electronics manufacturing complex on the San Francisco Peninsula underwent enormous changes from the early 1930s to the late 1970s. Electronics firms in the area employed a few hundred machinists and even fewer engineers in the early 1930s. In the larger scheme of the entire American radio industry, they were marginal. They operated in the shadow of the Radio Corporation of America (RCA) and the other large eastern firms that had a virtual monopoly on the production and sale of electronic components and systems. Forty years later the Peninsula had become a major industrial center specializing in electronic components.

Abstract:

This study investigated precipitation distribution patterns in association with atmospheric rivers (ARs). The Weather Research and Forecasting (WRF) model was employed to simulate two strong atmospheric river events. The precipitation forecasts were highly sensitive to cloud microphysics parameterization schemes. Thus, radar observed and simulated Z H and Z D R were evaluated to provide information about the drop-size distribution (DSD). Four microphysics schemes (WSM-5, WSM-6, Thompson, and WDM-6) with nested simulations (3 km, 1 km, and 1/3 km) were conducted. One of the events mostly contained bright-band (BB) rainfall and lasted less than 24 h, while the other contained both BB and non-bright-band (NBB) rainfall, and lasted about 27 h. For each event, there was no clear improvement in the 1/3 km model, over the 1 km model. Overall, the WDM-6 microphysics scheme best represented the rainfall and the DSD. It appears that this scheme performed well, due to its relative simplicity in ice and mixed-phase microphysics, while providing double-moment predictions of warm rain microphysics (i.e., cloud and rain mixing ratio and number concentration). The other schemes tested either provided single-moment predictions of all classes or double-moment predictions of ice and rain (Thompson). Considering the shallow nature of precipitation in atmospheric rivers and the high-frequency of the orographic effect enhancing the warm rain process, these assumptions appear to be applicable over the southern San Francisco Bay Area.

Abstract:

The aim of this study was to determine the effect of different fertilizer doses and drying methods on total phenolic contents and antioxidant activity of organic white tea (Camellia sinensis (L.) Kuntze) obtained from Hemşin Valley, region of Rize/Turkey. The determination of phenolic constituents was done by the Folin-Ciocalteau method and the determination of antioxidant activity by the FRAP method. The results showed that the phenolic content of white tea was as follows: 443,7- 506,2 µg GAE/g DW in the drying oven, 421,4- 473,6 µg GAE/g DW in shadow and 434,4- 485,2 µg GAE/g DW in the liofilizator. According to the FRAP method the antioxidant activity was as follows: 1130,1-1176,9 mg FeSO4/gr DW in drying oven, 1141,2-1157,1 mg FeSO4/gr DW in shadow and 1005,3-1183,2 mg FeSO4/gr DW in lyophylizator. The results revealed that different fertilizer doses and drying methods had important effects on the total phenolic content and antioxidant activity of white tea.

Abstract:

Steppe and forest-steppe belts in Central Altai occupy the bottoms of inter-mountain basins, expanded river valleys and surrounding mountains. The studied 4 steppe sites give sublatitudinal discontinuous range. The Kanskaya basin is rounded, the Ursulskaya one and the Chuya river (lower reaches) valleys are elongated from the east to the west while the steppe site of the Katun river valley — from the south to the north. The Kanskaya basin has a rounded shape while the Ursulskaya basin and the Chuya river valley (lower reaches) are elongated in the latitudinal direction, the steppe site of the Katun river valley — in longitudinal one. The configuration of the surrounding mountains is different: Kanskaya basin is surrounded by gradual mountain ridges with rare outcrops while valley boards of Katun and Chuya rivers are steep and rocky. Steppe belt ((600) 800–1100 m above s. l.) occupies the bottoms of the basins (expanded river valleys) and sun exposed adjoining slopes. Forest-steppe belt (1100–1400 m) occurs on the boards of the basins and includes 2 subbelts: the transitional lower (1100–1200 m) and the main upper (1200–1400 m) ones. It is continuous in the Kanskaya and the Ursulskaya basins and fragmented on the slopes of the Katun and Chuya river valleys. The plant cover structure of each belt is determined by altitudinal types of communities as well as by stands of rocky sites (so called petrophytic steppes). Studied steppes belong to classes Festuco-Brometea (FB) — order Stipetalia sibiricae and Cleistogenetea squarrosae (Cs) — orders Helictotrichetalia schelliani and Stipetalia krylovii. The forest vegetation within the forest-steppe belt goes to Rhytidio-Laricetea (RL) and Brachypodio–Betuletea (BB)and steppe meadows — to Molinio-Arrhenatheretea (MA) — order Carici macrouri–Crepidetalia sibiricae. The phytocoenotic spectra of altitudinal and petrophytic types of communities in steppe and in the upper part of forest-steppe belts are similar in all four sites. The key association in steppe belt is Fragario viridis–Stipetum capillatae (FB). These in the forest-steppe belt are larch herb forests of the ass. Anemonoido caeruleae–Pinetum sylvestris laricetosum (BB), steppe meadows of the ass. Cruciato krylovii–Poetum sibiricae (MA) and the meadow steppes of two vicarious associations — Violo dissectae–Achnatheretum sibiricae (FB) in the Kanskaya basin and Cruciato krylovii–Caricetum pediformis (FB) in three other sites. The petrophytic steppes belong to two associations: Kitagawio baicalensis–Cleistogenetum squarrosae (Cs) on the sun exposed slopes and Galio paniculati–Caraganetum arborescentis (FB) on shadow ones within the steppe belt, and to subass. Carici pediformis–Spiraetum trilobatae schizonepetosum multifidae (FB) that occurs only on sun exposed slopes within the forest-steppe belt. The differences of phytocoenotic spectra of studied sites are determined by the vegetation of the transitional stripe. Forest communities of the ass. Primulo cortusoidis–Laricetum sibiricae (RL) cover the gentle slopes of the Kanskaya and Ursulskaya basins, petrophytic stands of the ass. Carici pediformis–Spiraetum trilobatae schizonepetosum multifidae (FB) occupy rocky sites. Forest communities of the ass. Galio paniculati–Laricetum sibiricae (RL) are commonon the steep slopes of the Katun and Chuya river valleys and petrophytic stands belong to the ass. Kitagawio baicalensis–Cleistogenetum squarrosae (Cs). The bottom of the Katun river valley with the very specific mesoclimate is occupied by steppe ass. Artemisio frigidae–Stipetum krylovii (Cs) that in general is not typical for the studied area.

Abstract:

AT THE GALLERY OF THE SOCIETY OF PAINTERS in Water Colours in Pall Mall East in the autumn of 1855, Roger Fenton exhibited three hundred and twelve photographs taken in the Crimea. Undertaken with the patronage of Queen Victoria, Prince Albert, and the Duke of Newcastle, the then Secretary of State for War, Fenton’s photographic record was intended to inform the Victorian public of the “true” condition of the soldiers in what was fast becoming an unpopular war. In the catalogue, one photograph bore the title “The Valley of the Shadow of Death,” a title with both biblical and literary resonances for exhibition audiences in late 1855.1 Tennyson’s “The Charge of the Light Brigade” had been published in the Examiner on 9 December 1854, causing a sensation both at home and in the Crimea.2 Organized around variations on the refrain “Into the valley of Death / Rode the six hundred,” the poem assumed anthem-like status during the period when Fenton was in the Crimea. Filtered through the lens of Tennyson’s poem, Fenton’s photograph appears to record the traces of a charge or a battle scene that has just taken place.

Abstract:

AbstractOur study adds to the Quaternary history of eolian systems and deposits in western Wisconsin, USA, primarily within the lower Chippewa River valley. Thickness and textural patterns of loess deposits in the region indicate transport by west-northwesterly and westerly winds. Loess is thickest and coarsest on the southeastern flanks of large bedrock ridges and uplands, similar in some ways to shadow dunes. In many areas, sand was transported up and onto the western flanks of bedrock ridges as sand ramps, presumably as loess was deposited in their lee. Long, linear dunes, common on the sandy lowlands of the Chippewa valley, also trend to the east-southeast. Small depressional blowouts are widespread here as well and often lie immediately upwind of small parabolic dunes. Finally, in areas where sediment was being exposed by erosion along cutbanks of the Chippewa River, sand appears to have been transported up and onto the terrace treads, forming cliff-top dunes. Luminescence data indicate that this activity has continued throughout the latest Pleistocene and into the mid-Holocene. Together, these landforms and sediments paint a picture of a locally destabilized landscape with widespread eolian activity throughout much of the postglacial period.

Abstract:

Abstract We examined geographic patterns of diversification in the highly impacted San Joaquin kangaroo rat, Dipodomys nitratoides, throughout its range in the San Joaquin Valley and adjacent basins in central California. The currently recognized subspecies were distinct by the original set of mensural and color variables used in their formal diagnoses, although the Fresno kangaroo rat (D. n. exilis) is the most strongly differentiated with sharp steps in character clines relative to the adjacent Tipton (D. n. nitratoides) and short-nosed (D. n. brevinasus) races. The latter two grade more smoothly into one another but still exhibit independent, and different, character clines within themselves. At the molecular level, as delineated by mtDNA cytochrome b sequences, most population samples retain high levels of diversity despite significant retraction in the species range and severe fragmentation of local populations in recent decades due primarily to landscape conversion for agriculture and secondarily to increased urbanization. Haplotype apportionment bears no relationship to morphologically defined subspecies boundaries. Rather, a haplotype network is shallow, most haplotypes are single-step variants, and the time to coalescence is substantially more recent than the time of species split between D. nitratoides and its sister taxon, D. merriami. The biogeographic history of the species within the San Joaquin Valley appears tied to mid-late Pleistocene expansion following significant drying of the valley resulting from the rain shadow produced by uplift of the Central Coastal Ranges.

Abstract:

AbstractThe aim of this study was to present the use of the natural elements of the relief of river valleys such as changes in the width of the valley bottom, landforms occurring in the bottom of the valley, differences in height of the valley terraces as favourable for the location of the dam partitioning the bottom of the valley and creating a water reservoir for the requirements of historic metallurgical centres. The research was carried out based on DEM analysis from LiDAR data. Features were chosen in river basins with a rich metallurgical legacy. Analysis of the location of the former ironworks was carried out using Surfer 12 software. Five centres were selected due to the fact that only these are the only centres suitable for research which have survived to this day. Using the shaded relief models and contour coloured maps absolute differences in height between valley levels and other forms of relief occurring in the valley were analyzed, as well as the distribution of individual terrain forms in the designated part of the valley and changes in the width of the valley bottom were analysed in the context of the location of former metallurgical centres. On the basis of the contours of the former water reservoir visible in the valley relief, and using a surface area measurement tool (Surfer software), the range of the area that the reservoir could cover was measured. On the basis of the results obtained, it can be seen that convenient geomorphological conditions were used for the placement of selected weirs and metallurgical ponds which facilitated the damming of the valley. Natural narrowing of the valley bottom, or dunes and hills directly adjacent to the valley floor, were utilised during the construction of the dam. The rivers on which the furnace ponds were constructed are relatively small watercourses, so the weirs created by the constructors are not impressive. Their height is generally in the range of about 2 to 3 metres and their length is from about 120 to 300 metres. Nevertheless, they were effective in allowing sufficient water retention and the creation of furnace ponds with a measured area of about 4.5 ha to about 25 ha.

Abstract:

The areas where silver fir occurs in Switzerland are divided into main, minor or relict areas. In the main areas a wide distribution of silver fir is to be reckoned with. In contrast to traditional systems the emphasis of silver fir distribution lies somewhat lower and more clearly in pre-alpine regions. In the minor areas silver fir has withdrawn to shadowy slopes and is limited to low-lying valleys between the alps. In main valleys where the altitude of the valley bottom is higher than 1000 m.a.s.l. the current presence of silver fir is considered to be a relict of a postglacial warm period, favourable to silver fir, and not the result of human destruction.

Abstract:

In an 1856 issue of Harper's New Monthly Magazine the literary critic and biographer T. A. Richards conducted his readers through a house tour of famous literary residences in the Hudson River Valley. His itinerary and choice of authors were typical of the time. By using the picturesque vocabulary common to antebellum travel literature, Richards offered a vicarious glimpse into the domestic arrangements of successful writers and artists. He painted an edenic picture of gentility in the midst of the Hudson Valley's natural splendor. We read, for example, of the “broad lawns and slopes of Placentia,” the Hyde Park estate of the novelist James Kirke Paulding; and the “mysterious evening shadow” of Susan Warner's home on Constitution Island, just off West Point. “Dearest to us of all,” Richards added, was Sunnyside, Washington Irving's renovated Dutch farmhouse at Tarrytown. These elegant and vaguely romantic properties seemed utterly appropriate for the literary elite of the region. Like Hawthorne's Old Manse, they were architectural spaces indelibly suited to their masters' talents and temperaments.

Abstract:

AbstractTransient storage and erosion of valley fills, or sediment buffering, is a fundamental but poorly quantified process that may significantly bias fluvial sediment budgets and marine archives used for paleoclimatic and tectonic reconstructions. Prolific sediment buffering is now recognized to occur within the mountainous upper Indus River headwaters and is quantified here for the first time using optically stimulated luminescence dating, petrography, detrital zircon U-Pb geochronology, and morphometric analysis to define the timing, provenance, and volumes of prominent valley fills. This study finds that climatically modulated sediment buffering occurs over 103–104yr time scales and results in biases in sediment compositions and volumes. Increased sediment storage coincides with strong phases of summer monsoon and winter westerlies precipitation over the late Pleistocene (32–25 ka) and mid-Holocene (~8–6 ka), followed by incision and erosion with monsoon weakening. Glacial erosion and periglacial frost-cracking drive sediment production, and monsoonal precipitation mediates sediment evacuation, in contrast to the arid Transhimalaya and monsoonal frontal Himalaya. Plateau interior basins, although volumetrically large, lack transport capacity and are consequently isolated from the modern Indus River drainage. Marginal plateau catchments that both efficiently produce and evacuate sediment may regulate the overall compositions and volumes of exported sediment from the Himalayan rain shadow.

Abstract:

ABSTRACT In several glaciated valleys along the eastern front of the Lemhi Mountains, subalpine meadows are located along the central axes of the valleys, in positions immediately upvalley of arcuate Pinedale readvance moraines. The meadows are comprised of varying thicknesses of finegrained sediments which were impounded by the damning action of the moraines. These sediments, and pollen contained therein, record complex environmental fluctuations which accompanied déglaciation and postglacial recovery. The thickness of sediments in each meadow is a function of the proficiency of the arcuate moraines as dams. The presence of Glacier Peak B ash in one meadow illustrates that, at minimum, the lower one-third of that valley was deglaciated prior to approximately 11,250 yr BP. Over one meter of glacial-runoff sediments underlies the ash ; sedimentation rates in the meadow suggest that déglaciation in the lower portions of the valley may have been complete before 11,500 yr BP. Sedimentation rates slowed dramatically after 10,000 yr BP. A cold, early HoIocene climatic episode may have occurred around 7500 yr BP. Massive protalus landforms were deposited during the Indian Basin Advance. Later Neoglacial landforms were areally restricted to the most shaded, climatically-favorable locations.

Abstract. Rock slides and rock falls are the most frequent types of slope movements in Yosemite National Park, California. In historical time (1857–2002) 392 rock falls and rock slides have been documented in the valley, and some of them have been mapped in detail. We present the results of an attempt to assess rock fall hazards in the Yosemite Valley. Spatial and temporal aspects of rock falls hazard are considered. A detailed inventory of slope movements covering the 145-year period from 1857 to 2002 is used to determine the frequency-volume statistics of rock falls and to estimate the annual frequency of rock falls, providing the temporal component of rock fall hazard. The extent of the areas potentially subject to rock fall hazards in the Yosemite Valley were obtained using STONE, a physically-based rock fall simulation computer program. The software computes 3-dimensional rock fall trajectories starting from a digital elevation model (DEM), the location of rock fall release points, and maps of the dynamic rolling friction coefficient and of the coefficients of normal and tangential energy restitution. For each DEM cell the software calculates the number of rock falls passing through the cell, the maximum rock fall velocity and the maximum flying height. For the Yosemite Valley, a DEM with a ground resolution of 10 × 10 m was prepared using topographic contour lines from the U.S. Geological Survey 1:24 000-scale maps. Rock fall release points were identified as DEM cells having a slope steeper than 60°, an assumption based on the location of historical rock falls. Maps of the normal and tangential energy restitution coefficients and of the rolling friction coefficient were produced from a surficial geologic map. The availability of historical rock falls mapped in detail allowed us to check the computer program performance and to calibrate the model parameters. Visual and statistical comparison of the model results with the mapped rock falls confirmed the accuracy of the model. The model results are compared with a previous map of rockfall talus and with a geomorphic assessment of rock fall hazard based on potential energy referred to as a shadow angle approach, recently completed for the Yosemite Valley. The model results are then used to identify the roads and trails more subject to rock fall hazard. Of the 166.5 km of roads and trails in the Yosemite Valley 31.2% were found to be potentially subject to rock fall hazard, of which 14% are subject to very high hazard.

Abstract:

Abstract. Topographic shading, including both shaded relief and cast shadowing, plays a fundamental role in determining direct solar radiation on glacier ice. However, shading has been oversimplified or incorrectly incorporated in surface energy balance models in some past studies. In addition, no systematic studies have been conducted to evaluate relationships between shading and other topographic characteristics. Here we develop a topographic solar radiation model to examine the variability in irradiance throughout the glacier melt season due to topographic shading and combined slope and aspect. We apply the model to multiple glaciers in high-mountain Asia (HMA) and test the sensitivity of shading to valley aspect and latitude. Our results show that topographic shading significantly alters the potential direct clear-sky solar radiation received at the surface for valley glaciers in HMA, particularly for north- and south-facing glaciers. Additionally, we find that shading can be extremely impactful in the ablation zone. Cast shadowing is the dominant mechanism in determining total shading for valley glaciers in parts of HMA, especially at lower elevations. Although shading can be predictable, it is overall extremely variable between glacial valleys. Our results suggest that topographic shading not only is an important factor contributing to surface energy balance but could also influence glacier response and mass balance estimates throughout HMA.

Abstract:

Five Neogene floras in southern Washington and northwest Oregon indicate that the uplift of the Cascade Range occurred after ∼8–6 Ma. Miocene floras west of the range (Wilkes and Faraday floras) resemble paleofloras of correlative age to the east (Rattlesnake Hills, Palouse Falls, and lower Ringold). The statistical similarity of Miocene floras east and west of the Cascade Range axis demonstrates that a similar mesic, warm climate across the Pacific Northwest existed during the Middle and Late Miocene. These floras represent mixed hardwood–conifer forests that commonly contained Taxodium (bald cypress) and other mesophytic taxa. Based on Jaccard similarity coefficients calibrated with climatic data from modern plant communities, these paleofloras indicate a climate that was summer–wet, unlike that of the Pacific Northwest today. The annual precipitation was >100 cm, and the estimated mean annual temperatures of the fossil sites were 12–13 °C. The Miocene floras indicate that the development of a Cascade rain shadow in eastern Washington did not develop until after the deposition of the lower Ringold Formation in eastern Washington. That conclusion is reinforced by a well-documented climate and sediment sequence in the Snake River Valley, Idaho. There, well-dated pollen sections record a sharp decrease (by ∼30%–50%) in the annual precipitation regime after the Late Miocene Banbury Basalt and Poison Creek formations and before ∼3.4 Ma. The existence of extensive late Ringold sediments uplifted on the north side of Saddle Mountain indicates that the structural lifting of the Cascade Range had begun by 3.1 Ma (Pliocene). These data all suggest that the lifting of the Cascades occurred after Miocene time, and that the Cascade rain shadow developed during the Pliocene.

Abstract:

According to their ethnographers, the Bena of the Rivers in colonial Tanganyika emerged ‘from the shadows into the light of day’ when they undertook a great migration from the forested hills of the Iringa highlands to the treeless floodplain of the Kilombero valley in the late 1800's. The phrase had two meanings – on one level, it described the physical relocation of the Bena from the shadows of the forest to the open floodplain. On another level, ‘light of day’ was a metaphor for the remembered cohesion of a distinct Bena tribal identity, distinguishable from the ‘shadows’ of prior ethnic obscurity. The Culwicks considered the chief or mtema of this period, Ndaliwali, to be the founding ancestor of a new political lineage.The defining moment for the emergence of the Bena of the Rivers was the Battle of Mgodamtitu in 1874, when neighboring Hehe attacked Bena settlements in the foothills and forced the Bena permanently out of the highlands and into the valley. Once they had taken up their new residence, the Bena absorbed the existing settlements of the western end of the valley into their kingdom. They did this initially ‘under the guise of protector’, wrote the Culwicks, but their goal was political control of the region. By 1890, they wrote, most of the Ndamba as well as several smaller valley groups had become subjects of the Bena chief.The Battle of Mgodamtitu caused a ‘sudden and wholesale change’, according to the Culwicks, because Bena were forced to give up cattle keeping and take up rice cultivation; to learn the ways of the river and skillful use of canoes. They had previously looked down upon ‘rice and fish-eaters’, but after their migration they found that ‘there is but one crop really worth growing, and that is rice’.

Abstract:

Abstract. The vernal equinox total solar eclipse of 20 March 2015 produced a maximum occultation of 65.8–70.1 % over Switzerland during the morning hours (09:22 to 11:48 CET). Skies were generally clear over the Swiss Alps due to a persistent high-pressure band between the UK and Russia associated with a rather weak pressure gradient over the continent. To assess the effects of penumbral shading on near-surface meteorology across Switzerland, air temperature data measured at 10 min intervals at 184 MeteoSwiss weather stations were used. Wind speed and direction data were available from 165 of these stations. Additionally, six Swiss FluxNet eddy covariance flux (ECF) sites provided turbulent measurements at 20 Hz resolution. During maximum occultation, the temperature drop was up to 5.8 K at a mountain site where cold air can pool in a topographic depression. The bootstrapped average of the maximum temperature drops of all 184 MeteoSwiss sites during the solar eclipse was 1.51 ± 0.02 K (mean ± SE). A detailed comparison with literature values since 1834 showed a temperature decrease of 2.6 ± 1.7 K (average of all reports), with extreme values up to 11 K. On fair weather days under weak larger-scale pressure gradients, local thermo-topographic wind systems develop that are driven by small-scale pressure and temperature gradients. At one ECF site, the penumbral shading delayed the morning transition from down-valley to up-valley wind conditions. At another site, it prevented this transition from occurring at all. Data from the 165 MeteoSwiss sites measuring wind direction did not show a consistent pattern of wind direction response to the passing of the penumbral shadow. These results suggest that the local topographic setting had an important influence on the temperature drop and the wind flow patterns during the eclipse. A significant cyclonic effect of the passing penumbral shadow was found in the elevation range ≈ 1700–2700 m a. s. l., but not at lower elevations of the Swiss Plateau. This contrasts with an earlier theory that the anticyclonic outflow should reach as far as ≈ 2400 km from the center of the eclipse, which would have included all of Switzerland during the 2015 eclipse. Thus, measurable effects of penumbral shading on the local wind system could be even found at ≈ 2000 km from the path of the eclipse (that is, Switzerland during the 2015 eclipse), and our results tend to lend support to a newer theory that the anticyclonic cold-air outflow from the center of the eclipse only extends ≈ 1600 km outwards, with cyclonic flow beyond that distance.

Abstract:

Abstract. Since 1857 more than 600 rock falls, rock slides, debris slides, and debris flows have been documented in Yosemite National Park, with rock falls in Yosemite Valley representing the majority of the events. On 26 December 2003, a rock fall originating from west of Glacier Point sent approximately 200 m3 of rock debris down a series of joint-controlled ledges to the floor of Yosemite Valley. The debris impacted talus near the base of Staircase Falls, producing fragments of flying rock that struck occupied cabins in Curry Village. Several years later on 9 June 2007, and again on 26 July 2007, smaller rock falls originated from the same source area. The 26 December 2003 event coincided with a severe winter storm and was likely triggered by precipitation and/or frost wedging, but the 9 June and 26 July 2007 events lack recognizable triggering mechanisms. We investigated the geologic and hydrologic factors contributing to the Staircase Falls rock falls, including bedrock lithology, weathering, joint spacing and orientations, and hydrologic processes affecting slope stability. We improved upon previous geomorphic assessment of rock-fall hazards, based on a shadow angle approach, by using STONE, a three-dimensional rock-fall simulation computer program. STONE produced simulated rock-fall runout patterns similar to the mapped extent of the 2003 and 2007 events, allowing us to simulate potential future rock falls from the Staircase Falls detachment area. Observations of recent rock falls, mapping of rock debris, and simulations of rock fall runouts beneath the Staircase Falls detachment area suggest that rock-fall hazard zones extend farther downslope than the extent previously defined by mapped surface talus deposits.

Abstract. In June 2009, we conducted the first extensive glaciological survey of Alto dell'Ortles, the uppermost glacier of Mt. Ortles (3905 m a.s.l.), the highest summit of the Eastern European Alps. This section of the Alps is located in a rain shadow and is characterized by the lowest precipitation rate in the entire Alpine arc. Mt. Ortles offers a unique opportunity to test deposition mechanisms of chemical species that until now were studied only in the climatically-different western sector. We analyzed snow samples collected on Alto dell'Ortles from a 4.5 m snow-pit at 3830 m a.s.l., and we determined a large suite of trace elements and ionic compounds that comprise the atmospheric deposition over the past two years. Trace element concentrations measured in snow samples are extremely low with mean concentrations at pg g−1 levels. Only Al and Fe present median values of 1.8 and 3.3 ng g−1, with maximum concentrations of 21 and 25 ng g−1. The median crustal enrichment factor (EFc) values for Be, Rb, Sr, Ba, U, Li, Al, Ca, Cr, Mn, Fe, Co, Ga and V are lower than 10 suggesting that these elements originated mainly from soil and mineral aerosol. EFc higher than 100 are reported for Zn (118), Ag (135), Bi (185), Sb (401) and Cd (514), demonstrating the predominance of non-crustal depositions and suggesting an anthropogenic origin. Our data show that the physical stratigraphy and the chemical signals of several species were well preserved in the uppermost snow of the Alto dell'Ortles glacier. A clear seasonality emerges from the data as the summer snow is more affected by anthropogenic and marine contributions while the winter aerosol flux is dominated by crustal sources. For trace elements, the largest mean EFc seasonal variations are displayed by V (with a factor of 3.8), Sb (3.3), Cu (3.3), Pb (2.9), Bi (2.8), Cd (2.1), Zn (1.9), Ni (1.8), Ag (1.8), As (1.7) and Co (1.6). When trace species ratios in local and Po Valley emissions are compared with those in Alto dell'Ortles snow, the deposition on Mt. Ortles is clearly linked with Po Valley summer emissions. Despite climatic differences between the Eastern and Western Alps, trace element ratios from Alto dell'Ortles are comparable with those obtained from high-altitude glaciers in the Western Alps, suggesting similar sources and transport processes at seasonal time scales in these two distinct areas. In particular, the large changes in trace element concentrations both in the Eastern and Western Alps appear to be more related to the regional vertical structure of the troposphere rather than the synoptic weather patterns.

Abstract:

In Mexico City, 1583, Pedro Ocharte published the first book of vernacular sacred song in the Americas—the Psalmodia Christiana (Christian Psalmody) by Bernardino de Sahagún, a Spanish missionary of the Franciscan Order. Sahagún composed his book of 333 songs in the Nahuatl language during the second half of the sixteenth century to promote the formation of Catholic Mexica (better known as “Aztec”) communities in the central valley of Mexico. Well-received in its day as a primer on tenets of the Catholic faith, the life of Christ, and the virtues of the saints, it was denounced before the Inquisition in the eighteenth century and has otherwise existed in the shadow of Sahagún's monumental Historia general de las cosas de Nueva España, a pioneering anthropological study of the Mexica that did not become widely available until the nineteenth century. This article repositions the undervalued Psalmodia Christiana as a polished outcome of the anthropological research for which Sahagún is most remembered, setting in relief the understudied legacy of Western plainchant in the Christian evangelization of the New World and, more broadly, the extent to which the Mexica's native traditions were folded into the apostolic work of Catholic missionaries in post-Tridentine New Spain.
