Impact of urbanization on water quality and toxins in the Passaic River, New Jersey
No full textThe Passaic River is a significant water source in New Jersey which has experienced urbanization in its surrounding areas. Many citizens and scientists have grown concerns about the deteriorating water quality and increase in contamination. This research project will investigate the impact of urbanization on water quality, specifically focusing on the presence of toxins such as heavy metals and harmful algae. The research aims to determine if urbanization correlates with higher toxin concentrations in the river and to what extent these pollutants may affect the ecosystem and human health. The methodology includes researching heavy metal concentrations, nutrient levels, and algal bloom reports. Additionally, GIS mapping will be used to analyze land use change over time to draw a correlation between urbanization and pollution levels. Urbanization factors will include population density, land use change, and deforestation. Sources for urbanization data will be obtained from satellite imagery, census data, and historical land use maps. I anticipate the results to have a positive correlation between urbanized areas and higher concentration of toxins. These findings could provide valuable data to inform environmental management and urban planning decisions. This will hopefully promote cleaner water while having better public health policies in increasingly urbanized areas
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
Variations 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
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Tracing the Impact of Canadian Wildfires on Air Quality and Communities in the U.S. Northeast
No full textThe large wildfires that ravaged Canada in 2023 impacted air quality in the U.S. Northeast. Were these unlike any other in recent history? This question prompted a comprehensive examination of the historical context of such catastrophes. This research initiative focuses on taking. Deeper dive into past records within the air quality archives of the U.S. Northeast, seeking to find any historical parallels to have better insights into the magnitude of previous wildfire events. Beyond the ecological impacts, this study also delves into the societal and socioeconomic ramifications of these wildfires on the affected populations. This study also explores how communities cope with recover from these air pollution events. This study aims to paint a holistic picture of the complex aftermath of the large-scale wildfires Canada, and the areas affected beyond. My hypothesis is that there is no other time period that emulates what occurred with the smoke events in the summer of 2023. However, as climate is steadily changing and new temperature records are being broken each year, future fire and smoke events may become more common. To come to these conclusions, I will be investigation data archives of greenhouse gas and ppm levels, and visible observations made throughout the past hundred years. I hope to compare the data that spiked in the summer of 2023 to other years and thereafter further investigate as to what could have caused these spikes
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
