A Computational and Empirical Investigation of Graphemes in Reading

It is often assumed that graphemes are a crucial level of orthographic representation above letters. Current connectionist models of reading, however, do not address how the mapping from letters to graphemes is learned. One major challenge for computational modeling is therefore developing a model that learns this mapping and can assign the graphemes to linguistically meaningful categories such as the onset, vowel, and coda of a syllable. Here, we present a model that learns to do this in English for strings of any letter length and any number of syllables. The model is evaluated on error rates and further validated on the results of a behavioral experiment designed to examine ambiguities in the processing of graphemes. The results show that the model (a) chooses graphemes from letter strings with a high level of accuracy, even when trained on only a small portion of the English lexicon; (b) chooses a similar set of graphemes as people do in situations where different graphemes can potentially be selected; (c) predicts orthographic effects on segmentation which are found in human data; and (d) can be readily integrated into a full‐blown model of multi‐syllabic reading aloud such as CDP++ (Perry, Ziegler, & Zorzi, 2010). Altogether, these results suggest that the model provides a plausible hypothesis for the kind of computations that underlie the use of graphemes in skilled reading.     

Optimistic social comparisons of older adults low in primary control: a prospective analysis of hospitalization and mortality.

Social comparison can be used strategically to bolster the self-concept. Such use may constitute secondary striving for control, when primary striving through action is unattainable. On the basis of the life span theory of control, the authors hypothesized and found that social comparison judgments would predict physical health outcomes among older adults with low primary control perceptions in the health domain. Only among such respondents, after age, sex, activities of daily living, chronic conditions, and prior hospitalization were adjusted for, did more positive social comparison judgments predict significantly lower odds of hospitalization and death over the next 2--6 years as reported in provincial health records. In later life, optimistic social comparisons may contribute to better health by providing secondary control.     

VOCATION AND CREATION: BEYOND THE GENTILE‐HOMOSEXUAL ANALOGY

One strand of the church's conversation about homosexuality compares present‐day acceptance of homosexuals to the church's acceptance of Gentiles in Acts 15. In a previous article, “Gentiles and Homosexuals,” I presented the history of that strand. In a reply to my article, Olson proposes to reimagine the analogy via the “radical new perspective on Paul” and argues that doing so exposes problems with my original analysis. I defend myself against these criticisms, while also entering into the spirit of Olson's reimagined analogy. Expanding the scope beyond Acts to Paul opens up important facets that might otherwise be obscured. In particular, it includes voices that are sometimes silenced, and presses both sides for an account of sexuality grounded in vocation and God's purposes in creation.     

Correlates of unhealthy weight-control behaviors among adolescents: implications for prevention programs.

This study aimed to identify correlates of unhealthy weight-control behaviors in adolescents to guide the development of programs aimed at the primary prevention of disordered eating. A model explaining unhealthy weight-control behaviors was tested among 4,746 adolescents using structural equation modeling. Models fit the data well and explained 76% of the variance in unhealthy weight-control behaviors among girls and 63% among boys. Weight-body concerns were a strong correlate of unhealthy weight-control behaviors in both girls and boys. Models also emphasized the importance of weight-specific social norms within the adolescent's proximal environment. Findings suggest the importance of addressing weight-body concerns within prevention programs and extending interventions beyond classroom settings to ensure changes in weight-related norms among peer groups and family members.     

Undermining the axiological solution to divine hiddenness

Lougheed (Ratio 31:331–341, 2018) argues that a possible solution to the problem of divine hiddenness is that God hides in order to increase the axiological value of the world. In a world where God exists, the goods associated with theism necessarily obtain. But Lougheed also claims that in such a world it’s possible to experience the goods of atheism, even if they don’t actually obtain. This is what makes a world with a hidden God more valuable than a world where God is unhidden (where it’s impossible to experience atheistic goods), and also more valuable than an atheistic world with no God (and hence no theistic goods). We show that Lougheed never considers the comparison between a world where God hides and an atheistic world. We argue that it’s possible for a person to experience theistic goods in a world where God does not exist, a possibility Lougheed never considers. If this is right it undermines his axiological solution to divine hiddenness. We conclude by showing how our discussion of the axiology of theism connects to the existential question of whether God exists; that is, we show that the axiological question is (partly) dependent on the existential question.
