A Chemical and Historical Analysis of Beer: Discovering Brewing Styles and Beer Stages
Get PDFThis interdisciplinary project is designed to explore both the compositional qualities of beer during the brewing process and its impact on society from a cultural, economic, and social viewpoint. Comparing various styles of beer against each other in a historical, societal, and chemical lens allows for a deeper understanding of what creates a beer’s identity, and what makes it different from other styles. Here we analyzed two different styles of beer, a bock lager and a saison ale, in order to determine their chemical composition through their developmental stages to their final product. Based on previously published research and extended laboratory testing, methods were designed to run Nuclear Magnetic Resonance Spectroscopy on an array of beer samples in order to identify compounds present. This analysis reveals variations in chemical compositions between saisons and bocks and relates them to stereotypical flavor, body, and aroma profiles in order to get a complete understanding of their impact on the beer. Additionally, differences were seen between a beer\u27s boil and final product, resulting in a better understanding of beer\u27s development. Compounds in each style were identified by reference to established research results, creating evidence-backed assumptions of what each NMR peak represents. Since results from these findings are limited, the compounds possible to identify are therefore limited as well. Carbon NMR baselines were established by use of HSQC, a potential tool in future beer analysis. Humulones were discovered to be a major factor in a beer\u27s identity, a deep historical analysis as well as extraction methods were conducted in order to analyze this. Connecting this chemical analysis to each style’s history as well as beer’s history as a whole provides a consumer with a deeper knowledge about the product they are consuming and why it is the way it is

Artist Talk: Christie Anderson
No full textJoin us for an artist talk featuring Christie Anderson about her exhibition. The talk will take place at the Peeler Art Center in the University Gallery (upper level). During covid, the dioramas became a form of escapism, where viewers could pretend to shop in the konbini (convenience store), enjoy having friends over and playing in the kawaii bedroom, crafting in the pastel hobby room, or relaxing outside in the forest. The environments invite viewers into another world and my dolls are the tour guides. This event is free and open to the public.https://scholarship.depauw.edu/peeler_event/1021/thumbnail.jp

Strategic Advocacy: Doula Care, Liminality, and Reproductive Justice
Get PDFIn this paper, we explain the larger political economy in which doulas work, highlighting the nature of their liminality, and their role in the reproductive justice movement. We then draw on over 60 qualitative interviews with doulas to articulate experiences and perspectives, demonstrating the ways they use strategic advocacy to meet the needs of birthing people. Finally, we consider how doula policies and practices could support doulas without compromising their focus on the birthing person. We argue that doulas embody care ethics that are critical for reproductive justice as their work is about humanizing the birthing person, often in the face of a heavily medicalized or biomedical/technocratic approach to birth that is depersonalizing or worse

National Parks for Future Generations?: The COVID-19 Pandemic’s Impacts on National Parks and Tourism
Get PDFThis paper explores the complex relationship between tourism and the environment in U.S. National Parks, with a focus on the impact of the COVID-19 pandemic. It examines how increased visitation affects wildlife, the spread of invasive species, and the overall health of natural ecosystems. The author argues for a shift in public perception of national parks, emphasizing education, community engagement, and a deeper understanding of the interconnectedness of nature to ensure the preservation of these areas for future generations. The paper also discusses the role of park rangers and historical interpretations of wildlife and the environment, as well as the impacts of private enterprises within and around national parks, and how those contribute to the overall experience of the visitors
Rendering History: The Women of ACM-W
No full textThe Association for Computing Machinery (ACM) has more than 100,000 members circling the globe, including trailblazing women who created ACM-W (ACM’s Committee on Women in Computing) in 1993. This book, published in celebration of ACM-W’s 30th birthday, divides the history of ACM-W into three parts.
The first section provides a traditional history that details the evolution of ACM-W’s projects. In the next section, Rendering History allows the women of ACM-W to tell their own stories. What motivated them to trade personal time and energy for work that would change the face of computing for women and young girls? Among many others, Sue Black relates a story that spans her escape from two abusive homes to recognition for her computing accomplishments by both the late Queen of England and the current King. Kathy Kleiman describes her contributions to the field, including helping to rescue the wireless spectrum (now used by WiFi) from the (US) Federal Communications Commission’s plan to sell it. Bhavani Thuraisingham writes about her birth in Sri Lanka, an arranged marriage to a man eight years her senior, and cutting-edge research in the integration of cyber security and machine learning. The final section of the book provides an annotated bibliography of the research that launched ACM-W and continued to inform its projects over the next 30 years.
ACM-W advocates internationally for the full engagement of women in all aspects of the computing field, providing a wide range of programs and services to ACM members and working in the larger community to advance the contributions of technical women. The main theme of ACM-W’s 30-year history as detailed in this book is the organization’s maturation from a US-centric organization to a global leader in supporting the advancement of women in computer science.
“This is, quite simply, a book you won’t want to put down! What a wonderful collection of stories – blending personal and professional reflections – of many of the women who have been pioneers in computing and its roles in society, and in ACM-W. Gloria Childress Townsend is one of those pioneers and we owe her great thanks for putting together this captivating collection of stories, and for telling the very impressive and influential history of ACM-W.” - Bobby Schnabel, University of Colorado Boulder – co-founder of the National Center for Women & Information Technolog
“Marronage Beyond Slavery?” In Landscapes of Movement and Predation: Perspectives from Archaeology, History, and Anthropology
No full textRunaway slaves in the Americas were widely known as Maroons. In freedom, Maroons built new lives and created alternate spaces beyond the control of those who had enslaved them. This self-autonomy has offered researchers greater insight into the creation of African diaspora cultures absent the effects of white enslavers’ interference. This is not to say, of course, that slavery did not continue to affect Maroons following their flight from bondage. Indeed, Maroons’ fugitive status profoundly shaped their lives. The threat of reenslavement drove many into inhospitable terrain. Archaeologists have identified this strategy of retreat in fugitive slave groups across diverse... [excerpt from JSTOR
