Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
LANDOWNERS\u2019 ACCEPTANCE OF CHRONIC WASTING DISEASE MANAGEMENT : IMPLICATIONS FOR ACCESS TO PRIVATE LAND
No full textThesis (M.S.)--Michigan State University. Fisheries and Wildlife - Master of Science, 2025Management of chronic wasting disease (CWD) in cervids is dependent upon landowner access to private property. When access is allowed, CWD management strategies such as targeted removals and recreational hunter harvest can decrease local prevalence, and surveillance strategies can improve knowledge. However, the decision to allow property access rests on the landowner\u2019s acceptance of wildlife management actions. I distributed a survey to landowners in six U.S. states, which varied by region, state CWD prevalence, and county CWD prevalence. In Chapter 1, I assessed landowners\u2019 acceptance of CWD management and research strategies on their private property and explored a range of attributes that may influence their decision. Results indicated that landowners were more supportive of targeted removals than recreational hunter harvest for managing CWD but were most likely to allow surveillance strategies overall. Additionally, management efforts led by government wildlife agents were more widely accepted than those involving recreational hunters. Acceptance of CWD management was influenced by a range of attributes, including demographics, geographic location, disease prevalence, risk perceptions, hunting status, trust in wildlife agencies, and property characteristics. In Chapter 2, I evaluated landowners\u2019 preferences for targeted removal attributes and quantified their willingness to accept (WTA) financial incentives for deer removals. To do so, I employed a discrete choice experiment (CE) with three attributes: (i) removal restriction, (ii) implementing agency, and (iii) payment mechanism. Results indicated that many respondents were against targeted deer removals on their property and were unlikely to accept a feasible financial incentive to change their minds. However, among those willing to permit removals, targeting antlerless deer conducted by a state wildlife agent was preferred, suggesting it may be the most viable strategy to implement on private land. Various factors, including landowner demographics, geographic region, state and county-level CWD prevalence, and hunting status, influenced acceptance of targeted removals. This research will help improve property access by identifying landowners most likely to allow CWD management efforts and accept financial incentives, enabling managers to better prioritize resources and therefore reduce local CWD prevalence more effectively.Description based on online resource.

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
DISPLACED AND BURNT-OUT : A LOOK AT RECREATION EXPERIENCES IN SOUTHERN CALIFORNIA NATIONAL FORESTS
No full textThesis (M.S.)--Michigan State University. Sustainable Tourism and Protected Area Management -Master of Science, 2024When deciding to engage in an outdoor activity, recreationists often have a specific activity and setting in mind that they would like to participate in, like hiking or boating on a favorite trail or lake, respectively. When they set out for this experience but are unable to recreate in their desired way, they may leave feeling disappointed by the lack of engagement and misalignment between their experience and desired outcomes. To guide visitors to suitable alternative recreation experiences due to events such as extreme heat, wildfires, etc., a better understanding of displacement, information sources, perceived fire risk, and fire-related message fatigue is needed. The Los Padres, San Bernardino, Cleveland, and Angeles forests are four urban-proximate national forests in southern California. These forests are utilized by approximately 26 million people, to meet the local peoples\u2019 recreation needs. This thesis builds from a multi-part project and is organized into four distinct chapters. My findings draw attention to the main drivers and types of displacement experienced by recreationists, the sources used by recreationists to find out forest related information, and the role of message fatigue regarding wildfire risk perception. By using quantitative methods, I aim to address four research questions: (1) What form(s) of displacement, if any, have users experienced, and with that, what are the main drivers and types? (2) How do these drivers and types of displacement vary by (a) multigenerational households and (b) motivations (Cultural Ecosystem Services) (3) How much, if at all, are southern California residents who recreate locally in national forests experiencing message fatigue regarding wildfire and wildfire risk events? and (4) Do levels of message fatigue relate to their decision-making processes and perceptions of risk? Chapter 1 provides a comprehensive literature review of this thesis and these questions. Chapter 2 addresses questions 1 and 2, while chapter 3 addresses questions 3 and 4. Chapter 4 summarizes contributions across the two main research questions and chapters.Description based on online resource. Title from PDF t.p.

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
Statistical comparison of mass spectral data for positional isomer differentiation
Full text linkSuspected controlled substances are typically analyzed by gas chromatography-mass spectrometry (GC-MS) and the mass spectrum is compared to that of a reference material or library database for identification purposes. However, the identification is typically based on visual comparison of the spectra. With the increased prevalence of novel psychoactive substances, including positional isomers, identification in this manner is challenging due to high structural similarity among compounds.Previous work in our laboratory developed a statistical comparison method to compare two mass spectra (e.g., spectrum of the submitted sample compared to spectrum of the reference material). The work presented here demonstrates application of the statistical comparison method specifically for the differentiation of two sets of positional isomers. Each set of isomers was analyzed by GC-MS using two different instruments and with different injection parameters (e.g., different split ratios).Ultimately, association and discrimination of both sets of isomers was achieved. with one set discriminated at the 99.9% confidence level, while the other set was discriminated at the 99% confidence level. Varying split ratios and concentrations did have an effect on the number of discriminating ions reported, but discrimination was still possible. Overall, this research provides a method to identify positional isomers using mass spectral data routinely collected in a forensic laboratory.Thesis (M.S.)--Michigan State University.
