Managing Electronic Theses and Dissertations (ETD) Data

Where should students store data after they have completed their Electronic Thesis or Dissertation (ETDs)? The MetaArchive Cooperative has created the ETD+ Toolkit as an approach to improving research output management. This session will cover best practices in data curation and digital longevity techniques that will help students and faculty identify and offset risks and threats to their digital research footprints. We will discuss what to do with the data, how to handle copyright, version control, data organization, file formatting and metadata as well as where should these things be stored

Web Citation by Graduate Students: A Comparison of Print and Electronic Theses

This article reports on the Web citation behavior of print and electronic thesis authors at Iowa State and Virginia Tech from 1997 to 2003. Citations from print theses were compared with those submitted as an electronic thesis or dissertation (ETD). This study suggests that students who are required to publish their theses digitally exhibit citation behavior that is no different from students who produce their theses in print. Web citations accounted for 2.2 percent of citations in print theses and 5.4 percent of citations in ETDs. Persistence of Web citations was uniformly poor. The implications for library services and future research directions are discussed

New record for the distribution of the colonial hydroid Cordylophora caspia (Pallas, 1771) (Cnidaria: Hydrozoa) in Argentina

Cordylophora caspia is a colonial, athecate hydroid inhabiting both in freshwater and brackish habitats. Its global distribution is in part due to its ability to tolerate a wide range of salinity. It is considered an invasive species and its control is widely studied because of the industrial and ecological problems it causes in many environments. We report for the first time the occurrence of this hydrozoan in Nahuel Rucá Lake (Buenos Aires province, Argentina) with some notes on its internal and external morphology.Fil: Deserti, Maria Irene.

Metamaterial computation and fabrication of auxetic patterns for architecture

The paper investigates the potential of auxetics in architectural applications by means of computational design and additive manufacturing. This class of metamaterials expresses interesting behaviour related to the unusual characteristics of a negative Poisson’s ratio. Different patterns have been studied through a design workflow based on parametric software and the use of Particle Spring systems to support the form-finding process of bending-active auxetic structures. An advanced understanding of their bending capacity is explored with the use of variable infill patterns informed by structural analysis. Furthermore, principles for the design and fabrication of auxetic gridshells are discussed

Representability of Chern-Weil forms

In this paper we look at two naturally occurring situations where the following question arises. When one can find a metric so that a Chern-Weil form can be represented by a given form ? The first setting is semi-stable Hartshorne-ample vector bundles on complex surfaces where we provide evidence for a conjecture of Griffiths by producing metrics whose Chern forms are positive. The second scenario deals with a particular rank-2 bundle (related to the vortex equations) over a product of a Riemann surface and the sphere.Comment: Final version.

The study of control system of power supply for micro resistance welding

В роботі отримано математичні моделі вузлів джерела живлення для контактного мікрозварювання, синтезовано ланки, що корегують, а також проведено моделювання цього джерела живлення як замкненої системи регулювання при формуванні зварювального імпульсу спеціальної форми.The mathematical models of power supply units for micro resistance welding were obtained in this work. The simulation of the power supply as a closed loop control system was carried out for special form welding pulse generation

Barriers to Bystander Interventions for Sexual Assault - Department of Psychology Research Session

Bystander intervention programs have consistently demonstrated beneficial effects on community norms and intervention behaviors (Kettrey, Marx, & TannerSmith, 2019). However, much of the research fails to measure opportunities to intervene relative to actual behaviors (McMahon et al., 2015), and how these behaviors relate to a personal history of sexual victimization (Woods et al., 2016). This study aimed to examine the relationship between a bystander’s victimization history, perceived barriers, and bystander intervention. Data from undergraduate students (N = 583; 79.7% female; MAge=18.92) suggested that those with such a history perceive themselves as less able to identify risky situations, but are actually more likely to notice such situations and less likely to intervene. Therefore, it may be necessary to target perceived barriers as well as the disparity between observations and interventions in risky situations

Comparing Antibody-Coated Immune Beads with Flow Cytometry to Measure ß-2-Microglubulin+ Murine Spleen Cells

In diseases like AIDS, Multiple Myeloma, Multiple Sclerosis (MS), Type 1 Diabetes, and Systemic Lupus Erythromatosus the detection of major histocompatibility complex type 1 molecules (MHC 1) can be a helpful component of disease diagnosis and prognosis. Most somatic mammalian cells display to varying degrees major histocompatibility complex (MHC) class 1 antigen on the cell surface. MHC1 molecules consist of a polymorphic alpha a chain and a monomorphic beta chain, beta 2 microglubulin (ß2m). The ß2M composition is fairly constant within a species whereas the alpha chain is not. The polymorphic alpha chain is encoded by an MHC complex gene that is specific for each member of the species. The consistency of the ß2M protein within a species makes it a superior target to the variable a chains when attempting to quantify MHC1 molecules. Currently, there are no reagents available to identify the MHC1 antigen within an outbred population such as human or laboratory animals other than defined in bred mouse strains. In this study, the presence of MHC1 molecules on spleen cells from an outbred mouse strain (ICR strain) was evaluated by looking for monomorphic ß2m molecules. The two methods, which were used to obtain the numbers of ß2m+ mouse spleen cells, were flow cytometry and the antibody-latex bead method. Similar numbers of ß2m- positive cells were obtained using these two methods (7-9%). These results demonstrate that the antibody-coated beads are a suitable, less expensive and time saving alternative to determine the numbers of ß2m+ positive cells when compared to flow cytometry
