An Inconsistency in the Knowledge Argument

I argue that Frank Jackson's knowledge argument cannot succeedin showing that qualia are epiphenomenal. The reason for this is that there is, given thestructure of the argument, an irreconcilable tension between his support for the claim thatqualia are non-physical and his conclusion that they are epiphenomenal. The source of the tensionis that his argument for the non-physical character of qualia is plausible only on theassumption that they have causal efficacy, while his argument for the epiphenomenal characterof qualia is plausible only on the assumption that they are non-physical. Since these two argumentscannot be combined coherently, the most Jackson's argument can establish is thatqualia are non-physical.     

Following the Leader? Mormon Voting on Ballot Propositions

Why did Utah voters—most of whom are Mormons—vote in favor of repealing Prohibition in 1933, and against a modest relaxation of Utah's liquor laws in 1968? In answering this question, we illuminate some important facets of the political behavior of members of the Church of Jesus Christ of Latter‐day Saints. We hypothesize that Mormons are likely to “follow their leaders” on political questions when two conditions hold: (1) official endorsement of a position by LDS church leaders; and (2) internal agreement among those leaders. Each is necessary, but neither is sufficient alone. In 1933, only one of these two conditions held; in 1968 both did. Using ecological inference to generate estimates of individual‐level behavior of Mormon and non‐Mormon voters in Utah, we find that Mormon voters were significantly more likely to vote in accordance with the Mormon Church's official position in 1968 than in 1933. We further test our hypothesis by examining other referenda in states with a large Mormon population. We conclude with a discussion of when and how contemporary Mormon leaders get involved in political issues.     

Can we disregard the whole model? Omnibus non-inferiority testing for R2 in multi-variable linear regression and in ANOVA

Determining a lack of association between an outcome variable and a number of different explanatory variables is frequently necessary in order to disregard a proposed model (i.e., to confirm the lack of a meaningful association between an outcome and predictors). Despite this, the literature rarely offers information about, or technical recommendations concerning, the appropriate statistical methodology to be used to accomplish this task. This paper introduces non-inferiority tests for ANOVA and linear regression analyses, which correspond to the standard widely used F test for and R², respectively. A simulation study is conducted to examine the Type I error rates and statistical power of the tests, and a comparison is made with an alternative Bayesian testing approach. The results indicate that the proposed non-inferiority test is a potentially useful tool for ‘testing the null’.     

Mobile Communication and Civil Society: Linking Patterns and Places of Use to Engagement with Others in Public

This study examined whether and how mobile communication influences the extent to which one engages with new people in public settings. Contrary to our expectation, general use of the technology in public did not detract from conversing with strangers. Shifting focus from where one uses the mobile phone to how it is used, we found that uses for coordination and news each lead to increased conversations with strangers in public settings, while relational use detracted from them. The findings also reveal an interactive effect such that those who use mobile technology for news and frequently use it in public were more likely to engage with strangers in public. The discussion offers interpretation of the findings and directions for future research.     

Comorbid Substance Use and Anxiety Disorders in Adolescents

To explore the coexistence of substance use disorders and anxiety disorders in adolescents, we assessed adolescents presenting for treatment to an inpatient substance abuse treatment facility (SUH), an inpatient psychiatric treatment facility (IPH), and a community-based psychiatric facility (CMHC) for comorbid substance use and psychiatric diagnoses. Thirty subjects from each facility (N=90) were interviewed using the revised Child Schedule for Affective Disorders and Schizophrenia (K-SADS) and the Structured Clinical Interview DSM-III-R (SCID-R) for substance use diagnoses. Overall, comorbidity (anxiety and substance use disorders) prevalence was 67% (20/30) of adolescents in the SUH group, 33% (10/30) of the CMHC adolescents, and 33% (10/30) of the IPH adolescents. Alcohol and marijuana were the most frequently abused substances. Anxiety disorders commonly coexist with substance use disorders in adolescents. Early identification and treatment of anxiety disorders may in fact prevent substance abuse in this population.
