Early maturation processes in coal. Part 1: Pyrolysis mass balances and structural evolution of coalified wood from the Morwell Brown Coal seam

In this work, we develop a theoretical approach to evaluate maturation process of kerogen-like material, involving molecular dynamic reactive modeling with a reactive force field to simulate the thermal stress. The Morwell coal has been selected to study the thermal evolution of terrestrial organic matter. To achieve this, a structural model is first constructed based on models from the literature and analytical characterization of our samples by modern 1-and 2-D NMR, FTIR, and elemental analysis. Then, artificial maturation of the Morwell coal is performed at low conversions in order to obtain, quantitative and qualitative, detailed evidences of structural evolution of the kerogen upon maturation. The observed chemical changes are a defunctionalization of the carboxyl, carbonyl and methoxy functional groups coupling with an increase of cross linking in the residual mature kerogen. Gaseous and liquids hydrocarbons, essentially CH4, C4H8 and C14+ liquid hydrocarbons, are generated in low amount, merely by cleavage of the lignin side chain

The Scholarship of Civic Engagement: Defining, Documenting, and Evaluating Faculty Work

Civic engagement, which is presented as teaching, research, and service in and with the community, presents new challenges for evaluating faculty work as part of the reappointment, promotion, and tenure process. The nature of service learning, professional service, and participatory action research are examined as faculty work that can be scholarly (i.e., well-informed) and the basis of scholarship (i.e., contributing to a knowledge base). As such, examples of evidence for documenting the work and issues associated with evaluating dossiers are presented

B2 and G2 Toda systems on compact surfaces: a variational approach

We consider the B2 and G2 Toda systems on compact surfaces. We attack the problem using variational techniques. We get existence and multiplicity of solutions under a topological assumption on the surface and some generic conditions on the parameters. We also extend some of the results to the case of general systems.Comment: 28 pages, accepted on Journal of Mathematical Physic

Quantum statistics on graphs

Quantum graphs are commonly used as models of complex quantum systems, for example molecules, networks of wires, and states of condensed matter. We consider quantum statistics for indistinguishable spinless particles on a graph, concentrating on the simplest case of abelian statistics for two particles. In spite of the fact that graphs are locally one-dimensional, anyon statistics emerge in a generalized form. A given graph may support a family of independent anyon phases associated with topologically inequivalent exchange processes. In addition, for sufficiently complex graphs, there appear new discrete-valued phases. Our analysis is simplified by considering combinatorial rather than metric graphs -- equivalently, a many-particle tight-binding model. The results demonstrate that graphs provide an arena in which to study new manifestations of quantum statistics. Possible applications include topological quantum computing, topological insulators, the fractional quantum Hall effect, superconductivity and molecular physics.Comment: 21 pages, 6 figure

Planning and assessing to improve campus--community engagement

Two methods for assessing the scholarship of engagement at the institutional level are presented: (a) the Comprehensive Assessment of the Scholarship of Engagement (CASE), a systematic method that compiles information about service learning and community engagement, identifies campus strengths, and prioritizes planning areas, and (b) an institutional portfolio that provides a rich data base of descriptive and evaluative information

Conceptualizing Civic Engagement: Orchestrating Change at a Metropolitan University

Indiana University-Purdue University Indianapolis (IUPUI) has undertaken numerous initiatives over the past fifteen years that have contributed to the development, clarification, and increased understanding of civic engagement and its related components. This case study demonstrates how advancing the public purposes of higher education requires the commitment, persistence, vision, and good judgment of many, but in particular the Chief Academic Officer, who assumes pivotal responsibility for civic engagement as a fundamental aspect of faculty work and student learning

Differences in client and therapist views of the working alliance in drug treatment

Background - There is growing evidence that the therapeutic alliance is one of the most consistent predictors of retention and outcomes in drug treatment. Recent psychotherapy research has indicated that there is a lack of agreement between client, therapist and observer ratings of the therapeutic alliance; however, the clinical implications of this lack of consensus have not been explored. Aims - The aims of the study are to (1) explore the extent to which, in drug treatment, clients and counsellors agree in their perceptions of their alliance, and (2) investigate whether the degree of disagreement between clients and counsellors is related to retention in treatment. Methods - The study recruited 187 clients starting residential rehabilitation treatment for drug misuse in three UK services. Client and counsellor ratings of the therapeutic alliance (using the WAI-S) were obtained during weeks 1-12. Retention was in this study defined as remaining in treatment for at least 12 weeks. Results - Client and counsellor ratings of the alliance were only weakly related (correlations ranging from r = 0.07 to 0.42) and tended to become more dissimilar over the first 12 weeks in treatment. However, whether or not clients and counsellors agreed on the quality of their relationship did not influence whether clients were retained in treatment. Conclusions - The low consensus between client and counsellor views of the alliance found in this and other studies highlights the need for drug counsellors to attend closely to their clients' perceptions of the alliance and to seek regular feedback from clients regarding their feelings about their therapeutic relationship

A Service-Learning Curriculum for Faculty

The development of service-learning courses is contingent upon faculty. Institutions of higher education which are interested in service-learning can engage in faculty development activities in order to (a) develop a common understanding on campus concerning the nature of service- learning, (b) establish and maintain the academic integrity of service-learning, (c) increase the confidence of faculty as they implement a new pedagogy, and (d) increase the likelihood that service-learning is institutionalized in higher education. This article describes a curriculum for a series of faculty workshops: Introduction to Service-Learning, Reflection, Building Community Partnerships, Student Supervision and Assessment, and Course Assessment and Research. Each module provides a synopsis of topics and suggested readings for participants
