We examined the relationship between nocturnal respiratory disturbance and learning and compared learning in children with and without nocturnal respiratory disturbance. Subjects were 149 participants in a prospective cohort study examining sleep in children ages 6–12: The Tucson Children's Assessment of Sleep Apnea study (TuCASA). Sleep was assessed via home polysomnography. Intelligence, learning and memory, and academic achievement were assessed. Parents rated attention. Group comparisons were used to test the hypothesis that the group with an apnea/hypopnea index (AHI) of 5 or more (n = 77) would have weaker performance than the group with AHI less than 5 (n = 72). The group with AHI of 5 or more had weaker learning and memory though differences between groups decreased when arousals were taken into account. There was a greater percentage of Stage 1 sleep in the AHI 5 or more group, and Stage 1 percentage was negatively related to learning and memory in the sample (n = 149). There were negative relationships between AHI and immediate recall, Full Scale IQ, Performance IQ, and math achievement. Hypoxemia was associated with lower Performance IQ. Thus, findings suggest that nocturnal respiratory disturbance is associated with decreased learning in otherwise healthy children, that sleep fragmentation adversely impacts learning and memory, and that hypoxemia adversely influences nonverbal skills.

Euboulos' 'αγκελ⋯ων is represented by only four fragments (frr. 1–3 frr. 1–4 Hunter), all culled from Athenaeus, which tell us nothing about the plot of the play or about the identity of its titular character. R. L. Hunter, in his recent commentary on Euboulos, discusses at length the name 'αγκελ⋯ων and concludes that it could belong to either (1) a humble and poor man; (2) ‘a character from folklore notorious for sexual relations with his mother’ ; or (3)’ a wily slave such as those foreshadowed in Aristophanes and familiar from New Comedy'. In view of our ignorance of the play's plot, each of these possibilities has an equal claim to our consideration. I believe, however, that the context in which the fragments are embedded in Athenaeus allows us to refine our understanding of the name even further.

Among the many textual difficulties that beset Ovid's Ibis are two passages that allude, in an oblique fashion typical of the whole poem, to the iambographer Hipponax:

(1) et quae Pytheides fecit de fratre Medusae,

eveniant capiti vota sinistra tuo,

(447–8 La Penna)

(2) utque parum stabili qui carmine laesit Athenin,

invisus pereas deficiente cibo.

(523–4 La Penna)
