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
The Trajectory of Alcohol Use in Emerging Adulthood: Investigating the Roles of Alcohol Measurement and Educational Pathways
No full textInconsistencies in alcohol use measurement across studies and broad conceptualizations of post-secondary education experiences of young adults impede the comparison of research findings and our understanding of age-related shifts in alcohol use during emerging adulthood. This dissertation uses data from the Victoria Health Youth Survey (V-HYS), a 5 wave longitudinal study following 662 Canadian youth across the ages of 12-27. Study 1 examined the longitudinal associations among four measures of alcohol consumption (frequency, quantity, frequency of heavy episodic drinking and volume) from ages 15-25 and compared the ability of these measures to predict alcohol-related problems in emerging adulthood. Levels and rates of change across alcohol dimensions were moderately associated over time. However, measures of alcohol involvement significantly differed in their average rate of growth and in the prediction of alcohol-related problems in emerging adulthood. Heavy episodic drinking and volume showed the strongest associations in developmental trends and were similarly predictive of alcohol-related problems. The findings from this study support using measures of heavy episodic drinking or volume for assessing alcohol use and alcohol-related problems during emerging adulthood. Building on Study 1, Study 2 compared the trajectories of heavy episodic drinking during adolescence and emerging adulthood among youth in four different educational pathways: two-year college students, four-year university students, transfer students, and terminal high school graduates. This study also examined whether individual level factors could account for group differences in heavy drinking among the education groups. Terminal high school graduates consistently had the highest levels of alcohol use over time compared to all three post-secondary groups. Two-year college students had significantly higher levels of heavy drinking than university or transfer students when they enrolled, but university students had the greatest increases in heavy drinking after enrollment. However, differences in heavy drinking between post-secondary groups were completely accounted for by variations in the age at the time of enrollment. Taken together, the current findings illustrate that enrolling in post-secondary education, regardless of the type of institution, is associated with an increase in the frequency of heavy drinking during emerging adulthood and that this increase is greatest for younger students. However, the rates of drinking never exceeded that of the terminal high school graduates over time. These studies illustrate that the conclusions drawn about alcohol use trends during emerging adulthood may be contingent on the alcohol consumption measure used and conceptualizations of educational experiences. The results of the current studies provide recommendations to researchers about which measures of alcohol involvement to select for inclusion in future studies, and inform the optimal timing, targets, and contexts for alcohol prevention and intervention efforts during emerging adulthood.Graduate062
Risk of Injury: The Implications of Mental Health, Alcohol and Gender
No full textInjuries are a serious public health concern and identifying risk factors for injury is a research priority. Previous research consistently supports the link between alcohol and risk of injury and between mental health and alcohol use. There is also some research to indicate an association between mental health and risk of injury. Given the nature of these independent relationships, examining how these variables are inter-related could have significant implications for injury prevention and informing public health policies. There is however, a dearth of research examining how mental health and alcohol interact and contribute to injury risk. The present study examines the independent and shared contributions of mental health and alcohol to injury. Furthermore, gender differences in these relationships are examined. The results indicate both alcohol use and mental health are significantly associated with increased risk of injury. Moreover, a synergistic effect between alcohol and mental health on injury is found among women. The implications for these results in practice and policy are [email protected]
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
An evaluation of the alcohol total consumption model and development of the international model of alcohol harms and policies
No full textAlcohol is the most widely used psychoactive drug on earth and continues to be responsible for a substantial burden of death and disability. Mitigating these harms is an important focus of any healthful society. Population-level alcohol policy strategies may be employed to decrease these harms and improve population health. To assist towards these goals, this dissertation has two research objectives relating to the estimation and mitigation of alcohol harms: (1) to complete a series of studies regarding the Alcohol Total Consumption Model (TCM) and (2) to specify and test a novel alcohol health harms estimator and alcohol policy scenario modeler, the International Model of Alcohol Harms and Policies (InterMAHP).
The TCM is an important theory in alcohol studies and connects alcohol policies, per capita alcohol consumption and alcohol-attributable (AA) harms in a unified social theory. In brief, policies are expected to reflect on population-level consumption, which in turn is the most important predictor of alcohol harms. The TCM theorizes that change should flow directionally through the model – a policy expected to decrease consumption would be predicted to decrease alcohol harms. This theory has been critical towards informing alcohol control policies in the past five decades. In this dissertation, a series of studies were conducted to test the assumptions of the TCM, to test their continued viability. Study A is a comprehensive systematic review and series of meta-analyses that established the link between alcohol policies influencing day/hours of sale and outlet density and per capita consumption. Study B is a primary research study that examined the direct effect of a changed alcohol policy on alcohol-related ED visits, in the context of Saskatchewan. Studies C and D establish the link between alcohol consumption and AA mortality and morbidity through mathematical specification of InterMAHP. Next, the model was applied to the exemplar of AA mortality in Canada in 2016. Last, Study E extended InterMAHP functionalities to include modeling changes in AA harms expected from potential or realized per capita consumption changes resulting from policy change. An application was provided in the context of Québec.
The results of this dissertation research provide some support, in a modern context, to the relationships defined in the TCM. The findings suggest that the TCM continues to be a largely appropriate conceptual model in consideration of alcohol policy-making. InterMAHP provides global alcohol researchers with a novel model towards estimating the health harms of alcohol.Graduate2020-04-0
Alcohol and cocaine simultaneous polysubstance use: a qualitative investigation
Full text linkAlcohol is among the most common substance to be co-administered with a variety of other drugs. It is frequently used simultaneously (i.e., on the same occasion) with cocaine. The objective of this qualitative investigation was to explore the patterns, contexts, functions, harmful consequences, risk-taking behaviors, and gender differences associated with the simultaneous use of cocaine and alcohol. In-depth semi-structured interviews with simultaneous alcohol and cocaine users were conducted at a residential treatment centre in Ontario, Canada (n=10). Two independent coders conducted a content analysis of the transcripts. Results revealed that method of cocaine use was an important variable when describing a simultaneous use occasion. There was a wide variety of reported contexts, functions, and harms associated with simultaneous alcohol and cocaine use. This research contributes to a better understanding of the patterns, functions, and contexts of simultaneous use, along with the corresponding risk taking behaviors and harms in treatment clients
