Rhetorical Awareness of Student Writers at an HBCU: A Study of Reflective Responses in the Writing Center

The recent call for replicable, aggregable, and data-driven (RAD) research of writing center effectiveness motivated this study. In writing centers, the primary objective is to improve writers through one-to-one conversations. Improvement in writers, defined here in terms of rhetorical awareness, has proven difficult to measure. In this article, the authors describe how they developed a scale to measure rhetorical awareness, specifically purpose, genre, and audience awareness. Using both discourse and content analyses, they applied the scale to student responses on reflection forms collected over two semesters at an HBCU to see if rhetorical awareness might be observable and measurable. Although the responses of students who visited the center more than once within six months did not show changes in their rhetorical awareness, as the authors had hoped, the results seem to reveal more about the social context than individual students, suggesting that current-traditional pedagogy persists. Aggregating data with this methodology may open new lines of inquiry for researchers of writing and allow them to track trends in discourse on writing.University Writing Cente

A model for baryonic Regge trajectories compatible with the threshold behavior required by unitarity and asymptotic behavior in agreement with analyticity constraints is given in explicit form. Widths and masses of the baryonic resonances on the N and $\Delta$ trajectories are reproduced. The MacDowell symmetry is exploited and an application is given.Comment: 12 pages, 6 figure

Influence of ZN(II) and MN(II) on catalytic activity of aspartic proteinases of Candida albicans

The interaction of secreted aspartic proteinases Candida albicans (SAP C. albicans) with ZnCl2 and MnCl2 was studied. Logarithms of stability constant from the data of electronic spectroscopy were calculated: lgβ = 4,73±0,20 for the complex [SAP C, albicans - Zn(II)] and lgβ = 7,02±0,20 for the complex [SAP C. albicans - Mn(II)]. The composition and maximum accumulation of complexes in solution were calculated. The optimal conditions of hydrolysis of the substrate, HAS (human serum albumin) in the presence of proteinases were determined: [HSA]=0.004 g/ml, [SAP]=2.33 μM, pH=4.5, the time of incubation of 25 min. The activity SAP C. albicans in the presence of ZnCl2 and MnCl2 in different concentrations in optimal conditions of enzymic hydrolysis was estimated. For the first time the activating action of ZnCl2 on catalytic activity of proteinase in concentration 5×10-7 mol/1 was discovered. The maximal rate of enzymic reaction (Vm), the Michaelis constant (Km) and constants of effects in presence and absence as the effector of ZnCl2 were calculated. The estimation of albuminatic activity of C. albicans infections family in different diseases localization in the presence and the absence as the effector of ZnCl2 was evaluated

Lasing on the D_2 line of sodium in helium atmosphere due to optical pumping on the D_1 line (up-conversion)

A new method is proposed to produce population inversion on transitions involving the ground state of atoms. The method is realized experimentally with sodium atoms. Lasing at the frequency corresponding to the sodium D_2 line is achieved in the presence of pump radiation resonant to the D_1 line with helium as a buffer gas.Comment: 4 pages, 4 figures, Late

Thermodynamic aspects of materials' hardness: prediction of novel superhard high-pressure phases

In the present work we have proposed the method that allows one to easily estimate hardness and bulk modulus of known or hypothetical solid phases from the data on Gibbs energy of atomization of the elements and corresponding covalent radii. It has been shown that hardness and bulk moduli of compounds strongly correlate with their thermodynamic and structural properties. The proposed method may be used for a large number of compounds with various types of chemical bonding and structures; moreover, the temperature dependence of hardness may be calculated, that has been performed for diamond and cubic boron nitride. The correctness of this approach has been shown for the recently synthesized superhard diamond-like BC5. It has been predicted that the hypothetical forms of B2O3, diamond-like boron, BCx and COx, which could be synthesized at high pressures and temperatures, should have extreme hardness

Information Continuity: A Temporal Approach to Assessing Metadata and Organizational Quality in an Institutional Repository

This paper was presented at the 8th annual Metadata and Semantics Research Conference held in Karlsruhe, Germany, November 27-29, 2014.Repositories provide a vital infrastructure for an institution to aggregate and disseminate creative output, yet this task is only as successful as the effective organization of its content. The University of Kansas is currently undergoing a systematic review to analyze metadata and content organization in its own repository. This paper argues that for a full assessment to be achieved it is necessary to not view the repository as a fixed item, but as an entity with its own continuity. This temporal approach has a significant impact on establishing resource provenance for metadata policy adjustments, disciplinary migration, and resource extensibility. For any repository it is essential for ensuring long-term viability

Exploring the design space of metadata-focused file management systems

Operating systems both old and new are reliant on the venerable hierarchical file system. For some time now, however, attempts have been made to either define new file systems or to bolt on applications that offer much improved functionality to attach and use metadata. This is because researchers have shown that traditional file systems are not able to meet users' needs in terms of organising large numbers of files effectively, and to support expeditious retrieval of those files when they are needed at a later time. Numerous proposals for post-hierarchical file management systems have been described in the literature; researchers focus on different dimensions of such systems in order to solve or reduce identified limitations. In some cases this leads to significantly different file system architectures, while in other cases new functionality is added on top of a traditional system through special purpose user-space applications. Orthogonally, some proposals focus on tags while others favour named attribute-value pairs. Still other choices are, seemingly, made in an ad hoc and often implicit manner. This paper investigates the different dimensions and associated choices that participate in the proposal of new approaches and that affect their ability to improve on current systems. The Cartesian product of those dimensions and options forms a large design space; we map some of the existing literature onto that design space and discuss approaches to evaluate new proposals

Multi-factor service design: identification and consideration of multiple factors of the service in its design process

Service design is a multidisciplinary area that helps innovate services by bringing new ideas to customers through a design-thinking approach. Services are affected by multiple factors, which should be considered in designing services. In this paper, we propose the multi-factor service design (MFSD) method, which helps consider the multi-factor nature of service in the service design process. The MFSD method has been developed through and used in five service design studies with industry and government. The method addresses the multi-factor nature of service for systematic service design by providing the following guidelines: (1) identify key factors that affect the customer value creation of the service in question (in short, value creation factors), (2) define the design space of the service based on the value creation factors, and (3) design services and represent them based on the factors. We provide real stories and examples from the five service design studies to illustrate the MFSD method and demonstrate its utility. This study will contribute to the design of modern complex services that are affected by varied factors

Service Interaction Flow Analysis Technique for Service Personalization

Abstract Service interaction flows are difficult to capture, analyze, outline, and represent for research and design purposes. We examine how variation of personalized service flows in technology-mediated service interaction can be modeled and analyzed to provide information on how service personalization could support interaction. We have analyzed service interaction cases in a context of technology-mediated car rental service. With the analysis technique we propose, inspired by Interaction Analysis method, we were able to capture and model the situational service interaction. Our contribution regarding technology-mediated service interaction design is twofold: First, with the increased understanding on the role of personalization in managing variation in technology-mediated service interaction, our study contributes to designing service management information systems and human-computer interfaces that support personalized service interaction flows. Second, we provide a new analysis technique for situated interaction analysis, particularly when the aim is to understand personalization in service interaction flows
