Self-Pollination in Clarkia Breweri may Increase Inbreeding Depression over Generations
No full textThe self-compatible plant Clarkia breweri is pollinated by hawk moths. However, hawk moths are very unreliable pollinators. Lack of natural pollinators may increase self-pollination in C. breweri resulting in inbreeding depression. Over multiple generations, recessive alleles may accumulate in C. breweri populations if hawk moth populations decline, resulting in reduced fitness for these plants. I hypothesize that seeds from inbred populations of C. breweri will have lower seed viability and growth rates than seeds from outcrossed populations
Deep Learning: Chest X-Ray Classification Using Neural Networks
No full textX-ray images are the most common form of medical imaging used for diagnosis. Through the use of deep-learning techniques, we are able to group these images into different categories of disease in order to ascertain what disease a patient might have. By using what is known as pre-trained models and convolutional neural networks, all built from scratch, we are able to achieve varying levels of accuracy when attempting diagnosis
Student-Professor Relationships and Student Motivation
No full textStrong social relationships with a professor are critical for a student’s overall classroom success. It is often difficult to develop strong relationships with professors because of preconceived notions that students have about their professors. The purpose of this study was to determine whether Lake Forest College students’ perceptions of their professors affected their motivation to do well in courses. Surveys and interviews, with both students and professors, revealed that professors have a major impact on student comfort and confidence, which can positively or negatively affect student motivation
Pre-Raphaelite Women: Hysteria, Prostitution, and Suffrage
No full textIn 1848, as political revolutions swept across Europe, a group of rebellious British artists established a society aiming to revolutionize the art of the Royal Academy. The art of the Pre-Raphaelite Brotherhood not only challenged traditional style, but also created images that looked at the social issues of nineteenth century England. This paper argues that Pre-Raphaelite painters made images of prostitutes, suicides, and other “Fallen Women,” inspired by the “science” of phrenology, by medical thinking about hysteria, and by laws aimed at controlling women on the streets. In addition, these visual stereotypes of independent and unruly women then contributed to the campaign targeting the women’s suffrage movement
Warrantless Cell Phone Search and Seizure
Get PDFThis talk discusses the U.S. Circuit Courts of Appeals\u27 decisions regarding whether police are required by 4th Amendment procedure to obtain a search warrant to search through an individual’s cell phone content. Thus far, the U.S. Circuit Courts of Appeal are in conflict—some circuits believe that a warrant is required before searching the contents of a cell phone and other circuits disagree and permit warrantless searches. This discrepancy should be a signal to the United States Supreme Court to accept a case and settle the law on this issue so that the country has uniform police procedure. A decision to permit warrantless searches potentially infringes on our rights to privacy and conversely a court decision that would require a warrant prior to a search of a cell phone would be a check on overly aggressive police work
Recontextualizing Religion through Reading: Islam and Paradise Lost
No full textAs centuries of scholarship and academic curriculum indicate, John Milton’s Paradise Lost is arguably one of the most important and influential works in both the English literary canon and the Christian tradition. Interestingly, there is no comparable theologically based work of literature in Islam. What may come as a surprise is that Paradise Lost was incredibly popular among an Islamic readership. As early as the end of the nineteenth century, Muslim scholars have drawn comparisons between Paradise Lost and important works in the Islamic philosophical and literary traditions and have argued for Milton’s possible exposure to specific works, which would suggest a direct influence on his writing of Paradise Lost. This cultural convergence is especially interesting in light of the longstanding relationship of conflict between Islam and Christianity. This talk is a comparative study of Islam and Christianity through the lens of a book that holds special meaning to both of them
Ants in the Sky: Ant Communities on Green Rooftops from 2012–2018
No full textCities are rapidly expanding in the modern world, disrupting the natural landscape and altering native communities. The construction of green rooftops may serve as a replacement for some of the lost habitat from urbanization. In this study, we analyze and summarize seven years of ant-trapping data on seven rooftops in Chicago, Illinois, and its northern suburbs. We demonstrate how ant communities change on these islands in the sky as they develop. This research can inform the owners and operators of green rooftops and influence the maintenance of the garden in the future
Land-Use History as a Predictor of Bee Diversity and Abundance
No full textThe American tallgrass prairie is disappearing at an alarming rate. Bees are essential pollinators in prairies, and the loss of prairies reduces available floral resources and ground nesting spots. We examine foraging bee diversity in remnant prairie, restored prairie, and old-field sites. I hypothesized that bee diversity should be highest in remnant prairies, reflecting higher levels of native flower diversity. I also hypothesized that bees should prefer blue pan traps, based on bees’ abundance of photoreceptors that detect blue light. Using nonmetric multidimensional scaling, we found that land use type was a significant predictor of bee species diversity and abundance
