Multi-Proxy Record Of Holocene Paleoenvironmental Conditions From Yellowstone Lake, Wyoming, Usa, Sabrina R. Brown, Rosine Cartier, Christopher M. Schiller, Petra Zahajská, Sherilyn C. Fritz, Lisa A. Morgan, Cathy Whitlock, Daniel J. Conley, Jack H. Lacey, Melanie J. Leng, W.C. Pat Shanks Iii

Department of Earth and Atmospheric Sciences: Faculty Publications

A composite 11.82 m-long (9876e-67 cal yr BP) sediment record from Yellowstone Lake, Wyoming was analyzed using a robust set of biological and geochemical proxies to investigate the paleoenvironmental evolution of the lake and its catchment in response to long-term climate forcing. Oxygen isotopes from diatom frustules were analyzed to reconstruct Holocene climate changes, and pollen, charcoal, diatom assemblages, and biogenic silica provided information on terrestrial and limnological responses. The long-term trends recorded in the terrestrial and limnic ecosystems over the last 9800 years reflect the influence of changes in the amplification of the seasonal cycle of insolation on regional …

Legal Corpus Linguistics And The Half-Empirical Attitude, Anya Bernstein

Journal Articles

Legal writers have recently turned to corpus linguistics to interpret legal texts. Corpus linguistics, a social-science methodology, provides a sophisticated way to analyze large data sets of language use. Legal proponents have touted it as giving empirical grounding to claims about ordinary language, which pervade legal interpretation. But legal corpus linguistics cannot deliver on that promise because it ignores the crucial contexts in which legal language is produced, interpreted, and deployed.

First, legal corpus linguistics neglects the relevant legal context—the conditions that give legal language authority. Because of this, legal corpus studies’ evidence about language use perversely obscures and misstates …

Rosenstock-Huessy’S “Cross Of Reality” And Systems Theory, Martin Zwick

Complex Systems Faculty Publications and Presentations

This paper is a systems theoretic examination of Eugen Rosenstock-Huessy’s “cross of reality,” a structure that fuses a vertical spatial dyad of inner-outer and a horizontal temporal dyad of past-future into a space-time tetrad. This tetrad is compatible not only with the human-centered phenomenological point of view that Rosenstock-Huessy favors, but also with a world-centered scientific point of view. It is applied by him explicitly or implicitly to a wide variety of individual and collective human experiences. In this paper I mention a few examples of these applications from the realm of language, religion, and social critique. I also show …

Warmonger: Inflicting Denial-Of-Service Via Serverless Functions In The Cloud, Junjie Xiong, Mingkui Wei, Zhuo Lu, Yao Liu

Computer Science Faculty Research & Creative Works

We debut the Warmonger attack, a novel attack vector that can cause denial-of-service between a serverless computing platform and an external content server. The Warmonger attack exploits the fact that a serverless computing platform shares the same set of egress IPs among all serverless functions, which belong to different users, to access an external content server. As a result, a malicious user on this platform can purposefully misbehave and cause these egress IPs to be blocked by the content server, resulting in a platform-wide denial of service. To validate the Warmonger attack, we ran months-long experiments, collected and analyzed the …

Challenges And Coping: Perspectives Of Syrian And Iraqi Refugee Youth In Germany, Lina Alhaddad, Robin Goodwin, Patricia Kanngiesser

School of Psychology

Refugee youth constitute around a third of the refugee population in Germany. We studied the experiences of newly arrived Syrian and Iraqi refugee youth, aged 14 to 18 years (N = 20), in Germany. We utilized semi-structured interviews and thematic analysis to investigate (a) the main challenges faced by youth and (b) their main coping resources to deal with these challenges. We grouped challenges into three levels: the individual level, the immediate social level, and the broader societal level. The most frequently mentioned challenges in our sample related to psychological wellbeing, school, friendship, accommodation, and discrimination. Youth reported relying on …

Level And Gorenstein Projective Dimension, Laila Awadalla, Thomas Marley

Department of Mathematics: Faculty Publications

We investigate the relationship between the level of a bounded complex over a commutative ring with respect to the class of Gorenstein projective modules and other invariants of the complex or ring, such as projective dimension, Gorenstein projective dimension, and Krull dimension. The results build upon work done by J. Christensen [7], H. Altmann et al. [1], and Avramov et al. [4] for levels with respect to the class of finitely generated projective modules.

The concept of level in a triangulated category, first defined by Avramov, Buch- weitz, Iyengar, and Miller [4], is a measure of how many mapping cones …

Evaluation Of Brachiaria Brizantha Ecotypes Under Grazing In Small Plots, Valéria P. B. Euclides, Cacilda B. Do Valle, Manuel C. M. Macedo, M. P. Oliveira

IGC Proceedings (1977-2023)

An intense search for new cultivars amongst recently collected and introduced ecotypes from Africa is in effect since 1988, at the National Beef Cattle Research Center, of the Brazilian Agricultural Research Corporation (Embrapa Beef Cattle). After agronomic evaluations of a large collection, 21 ecotypes were pre-selected for multilocational trials and from these, eight were elected for evaluation under grazing. The objective of this trial was thus to evaluate the persistence and carrying capacity of these eight new Brachiaria brizantha ecotypes after two years of grazing. The experimental design was a randomized complete block with nine treatments and two replicates. The …

In Vitro Propagation Of Pennisetum Purpureum Schum., M. M. G. Karasawa, J. E. B. P. Pinto, A. V. Pereira, José C. Pinto, F. G. Silva

IGC Proceedings (1977-2023)

A protocol is described for rapid multiplication of elephantgrass (Pennisetum purpureum Schum.) through shoot tip culture. The plant growth medium consisted of basal medium of Murashige and Skoog (MS) and vitamins Wood Plant Medium (WPM). The medium was supplemented with 0.00; 4.44; 8.88; 13.32 and 17.76 μM of benzylaminopurine (BAP). The elephantgrass was micropropagated by axillary shoot proliferations. Maximum propagule proliferation occurred on Murashige and Skoog (MS) medium enriched with 4.4 μM benzylaminopurine (BAP), resulting an average of 4.0 shoots per explant from cultivar Mineiro and 2.19 from cultivar Pioneiro. The best height and root plantlets were obtained with …

'Stay-Green' And Non-'Stay-Green' Perennial Ryegrass In Field Swards With Different Intervals Between Cuts, D. Wilman, K. R. Kennedy, M. O. Humphreys

IGC Proceedings (1977-2023)

The purpose of this study was to investigate the effect of the 'stay-green' character, originally introduced into perennial ryegrass (Lolium perenne L.) for amenity purposes, on herbage yield, N concentration and colour in field swards of 'stay-green' forage ryegrass managed in different ways for agricultural use. The conclusions were that the introduction of the 'stay-green' character (1) confers greater greenness only at some times of year and only when there has been a sufficiently long period of regrowth, (2) is expressed only in older, as distinct from young, tillers, (3) reduces herbage yield, particularly when a long interval is …

Agronomic Evaluation Of Alfalfa Cultivars In Rio Grande Do Sul, Brasil, J. C. De Saibro, R. Battisti, T. M. S. Freitas

IGC Proceedings (1977-2023)

From April 1995 to June 1998, thirty five alfalfa (Medicago sativa L.) cultivars (cvs.) were evaluated in a field trial at the “Depressão Central” ecoclimatic region, in southern Brazil. Two years after sowing, 30 cultivars were excluded from the test due to their poor overall agronomic performance, mainly low forage DM yields. The remaining cultivars: Crioula (local genotype used as a check), Victoria, Rio and P 30 are hay-type cultivars while Alfagraze is a grazing-tolerant type. Twenty-two harvests were made and no significant differences were found for total DM yields among cvs. Crioula, Victoria, Rio and P 30; however, …

Switchgrass For Biomass Production, Monroe Rasnake, D. Parrish, Garry D. Lacefield, D. Wolf

IGC Proceedings (1977-2023)

Six cultivars of switchgrass (Panicum virgatum) were established in 1993 at Princeton, Kentucky, USA. Two harvest systems were used: two cuttings per year in mid-June and November and one cutting per year in November. Biomass yield and stand survival were evaluated. Lowland cultivars produced more biomass than upland cultivars in both cutting managements. Upland cultivars did better in a two cut system while the other cultivars showed little difference. Excellent stands of all cultivars were maintained under both cutting managements.
