Atypical antipsychotic treatment among immigrant and non-immigrant pediatric patients with attention deficit/hyperactivity disorder in British Columbia
No full textThis thesis is focused on characterizing differences in pharmacological treatment among immigrant and non-immigrant children with Attention-Deficit/Hyperactivity Disorder (ADHD). Multimodal approaches combining psychosocial and pharmacological interventions are recommended for the treatment of ADHD. Among pharmacological treatments, stimulant medications are among the most common and efficacious drug therapy used to manage ADHD symptoms. However, there are concerns around increasing use of medications, such as atypical antipsychotics, that lack substantive evidence and are not currently approved by Health Canada for the treatment of ADHD.
This thesis has two main studies: First, scoping review methodology was used to examine longitudinal trends, prevalence, tolerability, and safety of atypical antipsychotics among children with ADHD. No studies were identified relating to atypical antipsychotic use specific to immigrant children with ADHD, even though this review found that many children with ADHD still receive atypical antipsychotics. Atypical antipsychotic medications are often used to manage psychiatric comorbidity and/or aggressive and impulsive symptoms associated with ADHD. However, there is little evidence regarding the safety and tolerability of atypical antipsychotics to support the use of these medications as a first-line intervention among children diagnosed with ADHD.
Second, differences in first-line stimulant and atypical antipsychotic prescribing practices were examined among newly diagnosed immigrant and non-immigrant children with ADHD, living in British Columbia, Canada. Immigrant children were less likely than non-immigrant children to be dispensed a stimulant medication prescription in the 30-days following an incident diagnosis of ADHD. Among children, being older, male, and receiving treatment from a psychiatrist was associated with being dispensed an atypical antipsychotic prescription as a first-line intervention within 30-days of diagnosis. A latent class analysis (LCA) was conducted to account for sources of variability that may be associated with ADHD treatment. A high proportion of children with ADHD were not dispensed any prescription medications. Non-migrant boys had a 68% increased likelihood of being treated with atypical antipsychotics compared to their migrant counterparts. Together, the studies incorporated in this thesis underline the importance of examining relationships between structural determinants of health, health equity, and ADHD-related prescribing practices.Medicine, Faculty ofPopulation and Public Health (SPPH), School ofGraduat
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
Terms of Endearment: The Effect of Racial Epithets on Internalized Racial Oppression
Get PDFEarly research on racism traditionally focused on measuring beliefs and attitudes towards racial and ethnic groups. There is a need to examine internalized racial oppression and the mechanisms that seek to maintain and reproduce prejudice among Black populations. The objective of the current study was to gain insight into how usage of racial epithets among Black populations might influence the internalization of white racism. This study examined changes in scores on a post-internalized racial oppression measure after exposure to the racial epithet “nigger” among Black and white female participants. In this study, female York University (Toronto, Canada) students (n=30) were randomly assigned to one of three experimental vignette conditions. Pre-post scores of internalized racial oppression were assessed for each participant. The relationship between psychological resilience and internalized racial oppression was also explored. On average, Black participants obtained higher scores on a post-internalized racism measure (p < .001) but retained lower psychological resilience scores compared to their white counterparts. Results from this study suggest that exposure to the racial epithet “nigger” may unknowingly strengthen internalized racial oppression among Black female participants. Moreover, these findings demonstrate that Black participants with high levels of resilience are better able to mitigate the psychological and emotional discord associated with internalized racial oppression, compared to those with low levels of resilience
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
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
