Gene Duplication And Deletion, Not Horizontal Transfer, Drove Intra-Species Mosaicism Of Bartonella Henselae, Rachana Banerjee, Oshina Shine, Vyshakh Rajachandran, Govind Krishnadas, Michael F. Minnick, Sandip Paul, Sujay Chattopadhyay

Biological Sciences Faculty Publications

Bartonella henselae is a facultative intracellular pathogen that occurs worldwide and is responsible primarily for cat-scratch disease in young people and bacillary angiomatosis in immunocompromised patients. The principal source of genome-level diversity that contributes to B. henselae's host-adaptive features is thought to be horizontal gene transfer events. However, our analyses did not reveal the acquisition of horizontally-transferred islands in B. henselae after its divergence from other Bartonella. Rather, diversity in gene content and genome size was apparently acquired through two alternative mechanisms, including deletion and, more predominantly, duplication of genes. Interestingly, a majority of these events occurred in regions that …

Buried In Silence: Homosexuality And The Feighner Criteria, Stewart Justman

Global Humanities and Religions Faculty Publications

The diagnostic revolution that culminated in the third edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (1980) began with the publication in 1972 of the Feighner criteria, a set of rules for the identification of 16 disorders. While Feighner et al. claim that their diagnostic categories rest on solid data, the fact is that one was soon to be removed by the APA from its classification of mental disorders: homosexuality. However, the anomaly of an extinct category in a list of supposedly validated diagnostic criteria never became a point of discussion, quite as if the …

The Great Turning: A Call For Systems-Thinkers, Gabriella M. Demarce

Undergraduate Theses, Professional Papers, and Capstone Artifacts

David Orr, in an article on ecological intelligence reminds us that the modern world was shaped by people who did not understand that our social and economic systems could not coexist with the rest of the biological or natural systems on Earth (Orr, 1994). My research is rooted in Orr’s argument and discovering ways to shift this degrading paradigm. With my belief in the power of education in empowering youth and my background in environmental and climate change studies, I see a future in great need of people who holistically understand the functions of all types of systems and can …

Climate Change Induced Migration, Solutions & Implications, Jack M. Rinck

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The issue of migration is already a contentious issue in today’s political environment. Moving into the future, displacements of large numbers of people will continue to increase in both frequency and magnitude. One of the largest driving factors of future migrations will be anthropogenic climate change. This paper mainly focuses on sea level rise and the potential impacts changing oceans will inflict on coastal communities. Given projections of sea level rise and current coastal populations the potential for unprecedented levels of displacement is enormous. As such, there is a need for creative solutions that will aid in preventing, mitigating, and …

Bottom-Up Herbivore-Plant Feedbacks Trump Trophic Cascades In A Wolf-Elk-Grassland System, Trevor C. Weeks

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Top-down predator-prey effects that alter the abundance, biomass, or productivity of a population community across more than one link in a food web are referred to as trophic cascades. While these effects have been extensively studied in aquatic environments, fewer studies have examined trophic cascades in terrestrial ecosystems. And fewer still terrestrial studies have tested for trophic cascades between vertebrates and grassland vegetation. Across the globe, grassland plant biomass is driven by both precipitation and non-linear positive feedbacks between grazing and plant productivity, as predicted by the Intermediate Grazing Hypothesis. Yet little is known about the role that apex carnivores …

The Ideational Meaning Of Diagrams In The Malaysian And Singaporean Mathematics Textbooks, Sarveswary Velayutham

The Mathematics Enthusiast

A mathematical text is multimodal with different modes of communication, namely verbal language, algebraic notation, visual forms and gestures. This paper aims to compare and discuss the ideational meaning of visual forms in worked examples from Malaysian and Singaporean Grade Seven Mathematics textbooks on Lines and Angles. There are two structures in ideational meaning, namely narrative (with action) and conceptual (without action). Action diagrams represent ongoing mathematical activity whereas, without action diagrams represent mathematical objects. Document analysis and coding were carried on 57 geometrical diagrams found in the textbooks used in a 20-year period. The properties to identify a narratively …

Kim Williams: Professionalizing Domesticity In Montana And Abroad, 1923-1986, Emmett Ball

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Kim Williams was a renowned writer and naturalist living and working in Missoula, Montana in the 1970s and 80s. She gained national recognition for her regular guest appearances on National Public Radio’s program “All Things Considered,” where she offered home-spun lessons on frugality, naturalism, and happiness through simplicity. Williams’s professionalization of domesticity was the culmination of a lifelong battle in an attempt to reconcile her own personal conception of femininity against her conflicting aspirations for a professional career and a familial, domestic life. There is little scholarship analyzing Williams’s personal life, and no known scholarship has attempted to condense her …

Lessons From Leaders: Mainstreaming Corporate Valuations Of Impacts And Dependencies On Nature, Carmen L. Thissen, Jakki J. Mohr

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Historically, business practices have negatively affected the natural environment. Many environmental problems originated from businesses’ view of nature as a source of cheap inputs. Moreover, businesses haven’t accounted for negative environmental impacts on “natural capital” (e.g. water, forests, pollination, etc.) from manufacturing, pollution, toxic waste, shipping, and transportation. Given that “you can’t manage what you don’t measure,” various organizations are developing models and metrics to quantify business impacts on natural capital, and leading businesses are forging ahead with financial valuations. For example, the Kering Group displays their natural capital valuations through an interactive “Environmental Profit and Loss” calculator, displaying global …

Understanding And Measuring Net Positive Business Strategies, Luke Ruffner Robinson

Graduate Student Theses, Dissertations, & Professional Papers

Despite their attempts to mitigate ecological impacts through sustainability initiatives, businesses are a major cause of the world's ecological problems. Some progressive businesses are attempting to move beyond “net zero” in terms of achieving neutral environmental impacts and instead are now pursuing a goal of net positive. Net positive refers to the idea that business activities could contribute value-added benefits to earth’s ecological systems, for example, by using technologies that sequester and store carbon. However, except for a handful of high-profile corporate case studies, little is known about how companies are developing their strategies to become net positive and …

Complicity And Climate Change, Shalomita Kristanugraha

Graduate Student Theses, Dissertations, & Professional Papers

As individuals, how should we understand our personal complicity in climate change related harms? In this thesis, I argue that the predominant way we think of complicity within the Western moral paradigm—that is, as a distribution problem—is inadequate in helping us understand the nature of our complicity in climate change related harms. This inadequacy, in turn, psychologically hampers individual citizens residing in high-emitting nations of the Global North from effective and sustainable social and political engagement with climate change. To address the inadequacy and obstructions that result from it, I follow the discussion between Christopher Kutz and Iris Marion Young …

Evaluations Concerning The Halogen Bond And Hydrogen Bond Relationship, Daniel Adam Decato

Graduate Student Theses, Dissertations, & Professional Papers

The chemical advances of this century are likely to be driven by the ability to predict and control noncovalent interactions. While the hydrogen bond continues to captivate the interests of scientists, the development of non-traditional noncovalent interactions offers unique solutions to tackle chemical problems. Understanding the interplay between the ubiquitous hydrogen bond and other noncovalent forces will further fundamental knowledge thereby accelerating novel functional designs. This dissertation examines the nature of the hydrogen bond and halogen bond relationship.

With a renaissance in the early 2000’s, the halogen bond has become a functional alternative to the hydrogen bond. The halogen bond, …
