    A receipt by Annie E. Wall recording partial payment for a team of mules, 5 February 1864. The high price for the team suggests that this transaction took place in the Confederacy, where inflation had reached ruinous levels by early 1864

    Abstract: A receipt by Annie E. Wall recording partial payment for a team of mules, February 5, 1864.Scope and Content Note: The collection consists of a single receipt, recording the payment of 150byD.A.BoydtoWallaspartialpaymentforateamofmules,datedFebruary5,1864.Theremainderofthesumowed150 by D. A. Boyd to Wall as partial payment for a team of mules, dated February 5, 1864. The remainder of the sum owed--600--appears to have been due within a month of February 8, although the wording is not clear. The high price for the team suggests that this transaction took place in the Confederacy, where inflation had reached ruinous levels by early 1864.Biographical/Historical Note: Woman owner of a team of mules, 1864

    An investigation of secondary flow in a turbine blade with end wall profiling

    Full text link
    Secondary flows have been long recognised as a significant form of loss mechanism in turbomachinery. They have a major influence over the performance of the blade rows since they cause unsteadiness in the mainstream flow. This consequently affects not only the mechanical integrity of the blades but also causes extra loss. This research is aimed to reduce secondary flows using a novel method; end wall profiling. Profile 2 end wall was designed by Rolls Royce pic. with improved design features compared to its predecessor, Profile 1 end wall. Profile 2 end wall was manufactured and tested using the test facility available at the University of Durham. The flow was measured at two different axial positions, together with end wall static measurements and flow visualisation. The inlet flow conditions were also checked for consistency. These results were analysed and compared to Profile 1 and Planar end wall profile results, which have been studied previously by Hartland [1999]. Profile 2 end wall achieved better secondary flow reduction compared to the Planar end wall. However Profile 1 end wall still proved to be better compared to both Profile 2 and the Planar end wall. This project has provided a thorough understanding of the various flow mechanisms in turbines and the available techniques in eliminating secondary flows. The application of end wall profiling has still shown potential in being a reliable method. It is also important that the flow physics is understood in detail to determine the shape of the end wall profile that will be effective

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Business ethics and e-learning: a contradiction in terms?

    In seeking to stimulate the ethical awareness of first year undergraduates on business and public sector courses, the potential contribution of e-learning should not be underestimated. While ethics is traditionally associated with more discursive approaches, initially there is much to be gained from providing students with an interactive electronic facility which they can use at their convenience. If designed with due regard to the limitations of educational technology and modest aims, it can help students to become more ethically aware by familiarising them with the language and concepts of ethical discourse and to acquire the skills needed to evaluate situations from an ethical perspective. At Sheffield Hallam University, such a facility, based on the principles of progression and interactivity, is being developed within an action research framework. Involving close collaboration between tutors, those with relevant technical expertise and student volunteers, representing the interests of potential users, all concerned are committed to enhancing the quality and rigour of the first year student learning experience. The challenges faced have included working within the constraints imposed by the software platform, Blackboard 5, and ensuring that the facility is genuinely interactive rather than simply the replication of a paper based system; is user friendly; enhances learning and encourages users to build on the foundations laid. While face-to-face tuition must remain a key element in helping undergraduates become more aware of the ethical dimension of business life in its broadest sense, the project demonstrates that business ethics and e-learning are not a contradiction in terms

    Identification and characterisation of the Arabidopsis thaliana cell wall proteome: unravelling novel cell wall proteins and new potential functions of the plant extracellular matrix

    The application of the proteomic approach has facilitated efforts directed toward the mapping of the entire Arabidopsis cell wall proteome. Proteins were sequentially extracted from purified cell walls using 0.2 M CaC1(_2) followed by a urea buffer. The extracts were resolved via large format two dimensional polyacrylamide gel electrophoresis (2-D PAGE) and were visualised via Coomassie brilliant blue staining. The aim was to identify and characterise as many cell wall proteins as possible, with the hope of identifying novel cell wall proteins. Out of 325 spots visualised on the 2-D polyacrylamide gel, 144 gave a positive protein identification representing 104 different proteins. The identified proteins were divided into 3 categories. The first category included proteins that have been previously identified as plant cell wall proteins. The second category was designated to include novel cell wall proteins (hypothetical proteins) and the third category was made up of proteins, which had recognised functions, but had never hitherto been known to be secreted to the extracellular matrix. Among the identified novel cell wall proteins there were several that shared high homology with protein kinases. These proteins possessed all the characteristics of secreted polypeptides, such as the cleavable N-terminal signal peptide, and were found to lack both the transmembrane domain and the endoplasmic reticulum retention tetrapeptides (HDEL and KDEL). These observations suggested that, as in animal cells, plant cells had extracellular protein kinase activity (phosphorylation). This was supported by the recent discovery that plant cells secrete ATP to the extracellular matrix (Thomas et al., 2000). Verification of the occurrence of extracellular protein kinase activity was further strengthened by the identification of phosphorylated bona fide cell wall proteins and stress responses caused by the depletion extracellular ATP

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
