Impact of the North American Monsoon on Molt Migrant Passerines
Get PDFBreeding, molt, and migration place considerable yearly demands on migrating passerines in North America. Due to conflicts in energy allocation, many species have evolved migration strategies that prevent temporal overlap in these processes. However, there is recent evidence that some passerines which breed in western North America migrate to intermediate stopover sites to carry out molt, conflating molt and migration. Factors influencing the evolution of such a strategy are believed to include both aridity on breeding grounds and dependable flushes of late-summer productivity in the southwestern United States and northwestern Mexico. This productivity occurs due to the brisk rainfall of the North American monsoon, and it results in a dramatic increase in many types of food resources. In this study, I use precipitation records and pre-existing surveys of breeding birds in the Great Basin region to investigate the relationship between migration strategy and influence of monsoon precipitation. Specifically, I model abundance changes using various precipitation and population explanatory variables in five molt migrants and five non-molt migrant controls. This study did not provide strong evidence that monsoon rains have distinct effects on passerines of divergent migration strategies. However, I found that molt migrants may be subject to weaker density-dependent effects, possibly due to relaxed constraints on the molting ground
‘The Robinhood Effect’ - Digital technology in global financial markets and its effects on investor decision making
Get PDFWe are currently experiencing a revolution that is larger, arguably, than the industrial revolution, it’s the Internet, also known as the World Wide Web. The Internet has transformed how we live — how we talk, how we work, how we go about our daily business, and how we manage our finances on a global and individual level. In the late 1990s, an investor would search the World Wide Web and, within seconds, find 3,372 websites with the term investment,” today, the same search for “investment” yields 1,860,000,000 results. Today, as proven with GameStop and other popular ‘meme stocks,’ social media, powered by the Internet, has a significant impact on the way people invest and interact with the stock market. In this thesis, I explore the impacts of technology on the financial markets and how those technologies have changed how investors make decisions, as opposed to traditional investment styles
El mar y la gente: Hacia una contextualización de lo indígena en El botón de nácar
No full textEl presente trabajo analiza las ramificaciones ontológicas, epistemológicas, y políticas del botón de nácar, un documental hecho en 2015 por el cineasta Patricio Guzmán. El siguiente análisis busca poner esta obra cinemática en el contexto de la formulación y el desarrollo del estado-nación chileno, lo cual ha ocurrido a expensas de las personas indígenas de la zona. Se observa que se emplea significación verdaderamente descolonizada en representaciones y discusiones de espacios acuáticos, lo cual engendra avances teóricos que utilizo para contextualizar el filme. Se sostiene que los efectos políticos de dicha significación descolonizada se ponen en marcha productivamente cuando son vistos a través del lente del esencialismo estratégico, y también del lente de la memoria social de traumas sociohistoricos
No Going Back: Ground-Breaking Lab Sends Students to Balkan Route to Learn About Refugees--and Themselves
Get PDFA double major in global studies and anthropology with a minor in women’s, gender, and sexuality studies, Powers was in Istanbul networking, scouring the city, making contacts with LGBTI refugees and activists, finding people to share their stories as part of a project at Colby, the Insurgent Mobilities Lab. The lab, involving more than a dozen students, is researching the dynamics of migration along the Balkan Route that hundreds of thousands of refugees have traveled in a grave effort to seek a better life in Northern Europe
One Step at a Time: Robotics Lab Team Combines Talents in Quest for the Perfect Synthetic Tendon
Get PDFWhen Caitrin Eaton arrived at Colby a year ago, she named her new robotics lab C3PO. The name grabs students’ attention, but they’re drawn to the lab for another reason: Eaton’s cutting-edge research unites engineering and animal physiology to help robots walk more smoothly than Hollywood’s stiff-legged C-3PO robot

In Living Color: Newly discovered film shows the Colby of 80 years ago
Get PDFIn 1935 Frederick Kinch began making home movies using Kodak’s newly introduced 8 mm camera. He filmed his children, a few hunting trips, and his alma mater—Colby. The film he spliced together from two trips to Waterville has recently surfaced, providing rare moving images of both downtown and Mayflower Hill campuses
