Exploring the Changing Teaching Practices and Needs of Business Faculty at Santa Clara University

This report will present the findings and recommendations of a study designed to explore Santa Clara University (SCU) business faculty’s current and emerging undergraduate teaching practices. The study was led locally by researchers in the SCU Library, with parallel studies conducted at fourteen other institutions of higher education in the United States during the 2018-19 academic year. These studies were coordinated at the national level by Ithaka S&R, a not-for-profit research and consulting service that helps academic and cultural communities serve the public good and navigate economic, technological, and demographic change. Ithaka will publish a capstone report of major themes across all fourteen institutions in Winter 2020 and will include recommendations that libraries, universities, and business schools can use to support the changing teaching practices of their business faculty

Particle-antiparticle asymmetries from annihilations

An extensively studied mechanism to create particle-antiparticle asymmetries is the out-of-equilibrium and CP violating decay of a heavy particle. Here we instead examine how asymmetries can arise purely from 2 2 annihilations rather than from the usual 1 2 decays and inverse decays. We review the general conditions on the reaction rates that arise from S-matrix unitarity and CPT invariance, and show how these are implemented in the context of a simple toy model. We formulate the Boltzmann equations for this model, and present an example solution.Comment: 5 pages, v2: added reference, v3: some changes to text in response to comment

Ailleurs et autrement

Le réseau des services de santé mentale est en constante évolution. Il est passé d'un modèle relativement simple à un réseau de service complexe, incomplet, à idéologie multiple et aux résultats incertains qu'il convient maintenant de réviser. Commentant le contexte de l'élaboration de la politique de santé mentale, les auteurs décrivent ensuite une expérience de diversification et de sous régionalisation des services de santé mentale dans la région de Montréal. Après une description de la situation, des objectifs visés, du mode d'organisation et des sous-régions, les auteurs identifient les principaux problèmes rencontrés, les enjeux et des perspectives d'action. Ils font ainsi connaître les particularités et les réalités différentes qui constituent le grand Montréal.The network of mental health services is constantly in movement. From a relatively simple model it has become a complex service with a multiple ideology, its results are indetermined and have now to be revised. While commenting on the elaboration of a politic in mental health, the authors describe an experience where the mental health services in a Montreal region were diversified and reorganised in sub-regions. They then give an idea of the situation, the arms hoped for, the organisational mode, and the sub-regions; the main problems encountered are identified as well as the stakes and the areas of action. They uncover the particularities and the different realities that are the mainstay of the Greater Montreal

Baryon Number Violating Scalar Diquarks at the LHC

Baryon number violating (BNV) processes are heavily constrained by experiments searching for nucleon decay and neutron-antineutron oscillations. If the baryon number violation occurs via the third generation quarks, however, we may be able to avoid the nucleon stability constraints, thus making such BNV interactions accessible at the LHC. In this paper we study a specific class of BNV extensions of the standard model (SM) involving diquark and leptoquark scalars. After an introduction to these models we study one promising extension in detail, being interested in particles with mass of O(TeV). We calculate limits on the masses and couplings from neutron-antineutron oscillations and dineutron decay for couplings to first and third generation quarks. We explore the possible consequences of such a model on the matter-antimatter asymmetry. We shall see that for models which break the global baryon minus lepton number symmetry, (B-L), the most stringent constraints come from the need to preserve a matter-antimatter asymmetry. That is, the BNV interaction cannot be introduced if it would remove the matter-antimatter asymmetry independent of baryogenesis mechanism and temperature. Finally, we examine the phenomenology of such models at colliders such as the LHC.Comment: 10 pages, 9 figures. v2: references added, some typos corrected. v3: some small corrections to match published version, no change in conclusion

Managing and Querying Multi-Version XML Data with Update Logging

With the increasing popularity of storing content on the WWW and intranet in XML form, there arises the need for the control and management of this data. As this data is constantly evolving, users want to be able to query previous versions, query changes in documents, as well as to retrieve a particular document version efficiently. This paper proposes a version management system for XML data that can manage and query changes in an effective and meaningful manner
