Variations on the Author
No full text“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
Watercolor portrait of Mary Folger Brown by unknown artist, ca. 1833
No full textThe subject of this portrait, Mary F. Brown, was the niece of Captain Isaiah Folger of the schooner EXACT which brought the Denny party to Seattle. Mary's great uncle was Mayhew Folger, captain of the brigantine TOPAZ, and who rediscovered the Pitcairn Islands in 1808 where one of the HMS BOUNTY mutineers was still living. This portrait was painted on Nantucket Island in 1833, but Mary eventually made it to the Pacific Northwest where she married Captain Oliver Coffin, and they had a son Everett. Everett Coffin became the captain of the flyer TACOMA and other Puget Sound vessels.1 Painting; Materials: watercolor --board; Dimensions: Art: 7.375 in.H x 5.375 in.W ; Frame: 8.875 in.H x 6.875 in.

Introduction. The number of antral follicles in cattle is highly repeatable in individuals, while being highly variable between animals (Burns et al., 2005; Ireland et al., 2007). Furthermore, a high antral follicle number is associated with a greater number of transferable embryos following superovulation (Singh et al, 2004; Ireland et al, 2007). However, the relation between age of the cow and follicle numbers has not been investigated. Furthermore, the ability to phenotypically classify cows with respect to follicle number based on a single rather than multiple ultrasound examinations would be desirable to rapidly identify cattle with high responsiveness to superovulation. The aim of this study was to investigate the accuracy of a single ultrasonographic examination, performed on a random day of the oestrous cycle, and to assess the variability in the number of follicles in dairy cows of different ages.
Materials and Methods. Transrectal ultrasonography was performed on 116 dairy cows, aged from 2.6 years to 10.8 years, to assess the number of ovarian follicles ≥3 mm in diameter on a random day of the oestrous cycle. Based on this scan, a subset of animals was selected as follows: cows with less than 15 antral follicles ≥3 mm in diameter (Low group n= 8) and those with more than 30 follicles≥3 mm in diameter (High group, n=10). Both groups were synchronized with 2 injections of PGF2α (Estrumate®, Loughrea, Co., Galway, Ireland) 11 days apart and the number of follicles ≥ 3 mm in diameter was counted daily during an entire oestrous cycle. The correlations between follicle number and animal age and between a single ultrasound examination and the maximal number of follicles during follicular waves were analyzed using ANOVA.
Results. Amongst the 116 animals, the number of antral follicles ≥3mm in diameter per animal ranged from 4 to 44, with a mean (±SEM) of 17.99±0.78 (Fig.1). Cow age was not related to the number of follicles detected on a random day of the oestrous cycle (R2 = 0.0086; P=0.31). Amongst the subsets of animals, the mean (±SEM) number of follicles was 35.9±1.50 in the High group and 8.13±0.71 in the Low group. No difference (P=0.89) was detected between the two groups in mean age (High=5.28±0.43 years, Low=5.38±0.62 years). Numbers of follicles at the initial random scan were highly correlated with the maximal number of follicles observed during follicular waves of a complete oestrous cycle (R2 =0.7756; P <0.0001).
Conclusion. The number of antral follicles in the ovaries of dairy cows is highly variable among cattle but apparently not linked with cow age. Cows with consistently high or low numbers of follicles can be reliably identified through transrectal ultrasonography performed on a single random day of the oestrous cycle

Periodic Microstimulation of Single Mechanoreceptive Afferents Produces Frequency-Following Responses in Human EEG
No full text Kelly, Edward F., Mats Trulsson, and Stephen E. Folger. Periodic microstimulation of single mechanoreceptive afferents produces frequency-following responses in human EEG. J. Neurophysiol. 77: 137–144, 1997. Dense multichannel recordings of scalp electroencephalogram were obtained in the vicinity of primary somatosensory cortex, time-locked to repetitive train microstimulation of single, physiologically characterized skin mechanoreceptive afferents in the median nerve of a single human subject. Frequency-domain analysis of cross-trial averages for fast-adapting type one and slowly adapting type one afferents revealed prominent, topographically organized “driving” responses in the electroencephalogram at the frequency of stimulation, which vanished under various statistical and experimental control conditions. The responses also exhibited systematic declines in amplitude both across and within trials, and orderly changes in scalp topography as a function of the location of afferents' receptive fields on the hand. The observed response properties are tentatively explained in terms of characteristics of the pattern of afferent drive impressed on the cortex by microstimulation. </jats:p
