La guitarra con sentido y razón: How the Chilean New Song Defined a Generation
Get PDFThis thesis analyzes the development of the New Song movement in Chile from its inception in the 1950s with the music recovery efforts of Violeta Parra, through its heyday in the 1960s and early 1970s during the years of Salvador Allende's Popular Unity government, to its legacy following the Pinochet coup of 1973. This thesis examines the New Song movement's musical origins, political messages, and connections to the most pressing issues of its time, including the domestic urban-rural divide and the involvement of the ordinary people in the nation's political sphere.Histor
From Paradise to Plantation: Environmental Change in 17th Century Barbados
Get PDFThis paper examines the ways in which the environment of Barbados was altered after the founding of an English colony on the island in 1627. The rate and manner of change is addressed, as well as the ecology of the island before English colonization. Before English occupation, Barbados was primarily covered in thick tropical rainforest, and had no human population. Within several decades of settlement, the island was almost exclusively covered in sugar cane plantations, and supported a dense human population. The paper also looks at the consequences of environmental alteration. The change to a plantation ecology made many islanders wealthy and powerful, and made Barbados a major player in the world economy. But the changes made to the island ecosystem also impacted the health and mortality of the inhabitants, the economic growth of the colony, the prevalence of food shortages, and the heavy reliance on slave labor from Africa. Many of these consequences continued even after the 17th century, and some can be seen today.Histor
The Burning Question: Early U.S. Radiology and X-Ray Burns, 1896-1904
Get PDFEarly radiologists experienced occupational injuries that they called x-ray burns. Between 1896 and 1904, early U.S. radiologists debated the cause of these injuries. Using the American X-Ray Journal, I identify at least half a dozen competing theories. Notably, early U.S. radiologists seemed to resist the conclusion that their injuries were directly caused by exposure to x-rays. I argue that the early U.S. radiologists demonstrated vocational bias against concluding that the technology around which they were forging a new discipline was inherently dangerous. I also argue that this bias was left unchecked by a dearth of conclusive evidence that x-ray burns were directly caused by exposure to x-rays.Histor
For the love of nature : outdoor recreation and greenhouse gas emissions in Norway
Get PDFThe environmental impacts of leisure consumption have emerged as key factors that must be addressed in order to meet climate targets agreed upon by most nations. Outdoor recreation is a popular leisure activity which is considered to be an environmentally friendly practice that promotes care for the natural world. In Norway, outdoor life is a 26,000 million Kroner industry which accounts for 17,000 terajoules of energy use per year, more than any other leisure activity apart from holiday journeys by air. Meanwhile, the government continues to push for an increase in business development and value creation from nature. This points to a paradox between a strong valuation of pristine nature and high levels of consumption which characterize outdoor recreation in Norway. In this study we use a survey to investigate transportation use and gear purchasing habits among students pursuing a degree in outdoor recreation at select Norwegian universities and social media users who frequent groups related to Norwegian outdoor life. Using a hybrid life-cycle assessment it was estimated that the average participant releases between 3.4 (social media group) and 4.6 (student group) tons of carbon dioxide equivalent emissions per year in relation to outdoor recreation activities, with around 65% of these emissions coming from transportation and the remaining 35% coming from gear purchases in both groups. This is equal to around one fifth of the average Norwegian’s yearly greenhouse gas emissions and is, by itself, more than double the per capita boundary required to limit global temperature rise to 2 degrees Celsius. In addition, regression analysis showed that personal beliefs and self-evaluated motivating factors did not play a significant role in mediating consumption behavior among the participant groups. Instead, level of disposable income was the best predictor of environmental load. This indicates that the facade of a green lifestyle based on ecological values masks the global environmental consequences of excessive consumption related to outdoor recreation activities
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textVariations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Pandemics, Climate Change, and Social and Racial Justice
No full textIn the current political climate, debates about COVID-19 and about climate change have pitted denialists against those who accept the realities of science and its ability to study, explain, and solve these problems. But while science can provide information about the physical realities of pandemics and climate change, it doesn’t address the political, social, and economic causes of these crises. Chomsky argues that science is not enough; we need to explore how the very same social and economic structures that entrench inequality are also at the root of both emerging pandemics like COVID-19 and of the climate crisis we are facing. This presentation was part of the Contemporary Issues Faculty Lecture Series and was co-sponsored by the Earth Day Planning Committee
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
