Entrainment, transport and concentration of meteorites in polar ice sheets

Glaciers and ice sheets act as slow-moving conveyancing systems for material added to both their upper and lower surfaces. Because the transit time for most materials is extremely long the ice acts as a major global storage facility. The effects of horizontal and vertical motions on the flow patterns of Antarctic ice sheets are summarized. The determination of the source areas of meteorites and their transport paths is a problem of central importance since it relates not only directly to concentration mechanisms but also to the wider issues in glaciology and meteorites. The ice and snow into which a meteorite falls, and which moves with it to the concentration area, encodes information about the infall area. The principle environmental conditions being former elevation, temperature (also related to elevation), and age of the ice. This encoded information could be used to identify the infall area

Digital Currency Policy and Accountability Technical Framework

Computer-implemented systems and methods for digital currency transaction guarantors and double spending protection are described herein. A verified observer may be defined for a given transaction depending on certain criteria required by the verified observer such that any liability incurred for failure of the given transaction or an abuse of a system in the given transaction is the sole responsibility of the verified observer. When a coin is deposited to a digital currency storage device, a gadget may be bound to the coin by a verified authority or the digital currency storage device such that when the coin is used in a transaction the gadget generates an output to prevent double spending of the coin

The Kodiak Study: Narratives of Diversity and Acceptance on the American Frontier

This article describes a qualitative study of diversity and acceptance on the American frontier comprised of interview data and ethnographic observations gleaned from a sample of residents on Kodiak Island, Alaska. Convenience and snowball sampling methods were used to select the study population, after which individual interviews with people who are members of various cultural groups were completed by the researcher. Also included in the study are elements of anthropological investigation, historical context and thick description. The data were analyzed using (primarily) narrative and thematic analysis placed in the cultural context of life on Kodiak Island. Findings suggest that multiple cultures can peacefully co-exist, and in fact co-create, a social milieu that is greater than the sum of its parts while maintaining independent cultural integrity

Case Studies in multiliteracies and inclusive pedagogy: Facilitating meaningful literacy learning

This thesis presents the results of a study designed to examine ways to engage and scaffold primary school students who experience literacy learning difficulties. Utilising a pedagogy of multiliteracies, proposed by the New London Group (1996, 2000), and a framework for inclusive pedagogy (Florian, 2014), this thesis sought to investigate ways to facilitate meaningful literacy learning for students who experience challenges when participating in print-based classroom activities. A qualitative case study approach was adopted to support the broader sociocultural and multiliteracies perspective that underlies the theoretical direction of this research. Three student case studies were constructed illustrating the students’ in-school and out-of-school literacy practices. Research data indicated that while these students exhibited strong engagement with multiple literacies in their out-of-school environment, their experiences in a classroom context were, at times, challenging and marginalising. During the fieldwork period, which took place in a Western Australian Year 6 primary classroom, a multimodal literacy activity was implemented over one school term. This activity required students to: 1. Audioread the novel The Bad Beginning 2. Create a storyboard utilising the iPad app Kid’s Book Report and 3. Create an iMovie review about the novel. Data analysis revealed that engagement with the multimodal literacy activity emerged in similar ways for the case study students. These students appeared to be engaged with the literacy activity when they were: • Activating prior knowledge and immersed in meaningful practices via situated learning. • Experiencing opportunities to create meaning in multiple ways. • Fostering shared meanings - scaffolded within a community of practice. Results indicate that engagement with multiple literacies, beyond the printed word, allowed the students to navigate literacy within various contexts. Exploring multimodal ways to present their thoughts further enhanced the students’ engagement with the multimodal literacy activity. This study provides insight into key areas in the field of literacy research and contributes to understandings of: multiliteracies; inclusive pedagogy; sociocultural approaches to literacy; and open-ended and flexible approaches to literacy learning. The study may be of interest to pre and in service primary school educators and education researchers and policy makers

Effects of arterial pCO2 on IgG absorption efficiency in neonatal Holstein calves

Absorption of colostral Ig within the first 24 h of life provides the neonate with passive immunity. Delayed first feeding of colostrum, low colostral Ig concentration or compromised metabolic state may reduce the apparent efficiency of Ig absorption (AEA) calculated as the mass of Ig in plasma (g) divided by Ig intake (g). Objectives of this study were to determine if elevated arterial pCO2 (PaCO2) in blood reduced AEA in calves and to determine if assisted ventilation of animals with elevated PaCO2 increased AEA. Holstein calves (n = 48) from primiparous and multiparous dams were separated at birth and blood was collected at 1 h and analyzed for PaCO2, arterial pO2 (PaO2), arterial pH (pHa), arterial actual bicarbonate (HCO3-), and base excess. Three treatments were assigned based on PaCO2 at I h: non respiratory acidosis (NA, n = 19), respiratory acidosis-not ventilated (ANV; n = 17), and respiratory acidosis-ventilated (AV; n = 12). Assisted ventilation was administered via Ambu Bag™ with mask at 1.5 h. Calves received 12 assisted breaths per min for 5 min. Post ventilation blood gas analysis indicated this method reduced PaCO2. Mean I h PaCO2 for calves on NA, ANV and AV treatments were 45.52, 53.04, and 53.22 (SE = 0.71) mm of Hg, respectively. Blood was sampled by jugular venipuncture at I, 13, 25, 37, and 49 h for analysis of plasma IgG by single radial immunodiffusion. Evans\u27 blue dye (1.5 ml) was injected into the jugular vein for estimation of plasma volume and AEA. Treatment had no effect on AEA at 25 h, plasma IgG at 13,25 or 37 h or plasma volume at 25 h (P \u3e 0.10). Mean AEA, plasma IgG and plasma volume at 25 h of age were 26% (SE = 1.5), 11.73 g/L (SE = 0.50) and 3 .422 L (SE = 0.001), respectively. Regression of AEA and plasma IgG on PaCO2 at 1 h indicated no effect of 1 h PaCO2 on IgG absorption. Results from this study indicate that acquisition of passive immunity was not inhibited by elevated PaCO2 at 1 h

The history of Methodism in Southern California and Arizona, 1850-1939

Thesis (Ph.D.)--Boston UniversityThis dissertation describes the historical development of Methodism in Southern California and Arizona from its foundation to 1939. It considers major developments, activities, and leadership, and it evaluates these, especially as they have had influence upon the Church; and it evaluates the relative strength and activity of the two branches of Methodism which were present in Southern California and Arizona previous to unification. The history is unfolded in six main divisions: The Methodist Episcopal Church in Southern California Through 1876; The Methodist Episcopal Church, South, in Southern California through 1870; Tihe Methodist Episcopal Church, South, 1870-1939; The Methodist Episcopal Church, 1876-1939; Methodism in Arizona; Unification. While both denominations labored in Southern California before the Civil War--the Methodist Episcopal Church beginning in 1853 and the Methodist Episcopal Church, South, beginning in 1854--the work was spasmodic and was totally reorganized after the war. The Los Angeles Conference of the Southern Church was organized in 1870, and the Southern California Conference of the Northern Church was organized in 1876. Southern Methodism was numerically much weaker than Northern Methodism in Southern California, but its lay organization was considerably more developed. The major project of the Southern Cburch was Trinity Church in Los Angeles. This church was a pioneer in the development of the Epworth League, and two of its pastors became bishops of Southern Methodism. Lack of finances hindered the Southern Church in many fields of endeavor. The Homer Toberman Deaconess Home was its major institutional achievement. Only on the issue of modernism did Southern Methodism here find itself involved in disruptive controversy. Among the leaders of Southern Methodism from Southern California were Grover Emmons, founder of "The Upper Room," and Robert Shuler, one of Methodism's most controversial figures. Northern Methodism grew rapidly and expanded widely after its organization in Southern Galifornia in 1876. Six bishops and numerous educational leaders came from the Southern California conference. Its educational requirements for membership were early among the highest in all Methodism. It was a leader in finding a solution to the entangled pension problem, and it was a pioneer in the matter of minimum salary for the ministry. The founding and developing of the University of Southern California was another notable achievement of the Conference. The outreach of the Conference to other races and nationalities was outstanding. Especially significant were the Church of All Nations, Spanish American Institute, and Plaza Community Center. Nine other institutions, ministering to the sick, the retired, students, and orphans, were established. The Conference did not escape divisive controversies. The most notable of these were: (1) the war issue, leading to the dismissal of a District Superintendent; (2) sanctification, leading to the founding of the Church of the Nazarene. Both denominations entered Arizona in 1870, but work there never assumed the proportions that it did in Sou1thern California. Northern Methodism was the stronger of the two. Hospitals in Phoenix and Tucson were probably the best achievements of both denominations. Unification passed by majority vote in Southern California and Arizona in 1925, but some Southern Methodist opposition was quite noticeable. It passed again in 1938 with several Northern Methodists opposing it because of the proposed inclusion of the Central Jurisdiction. In conclusion, it is evident that the individual 272 Conferences, especially in Southern California,, made important contributions to their respective denominations. It is also apparent that Northern Methodism was considerably stronger than Southern Methodism, expanded further and more rapidly, furnished more leaders to the Church as a whole, and was able to undertake a wider institutional ministry
