Fishes of the Strawberry River System of Northcentral Arkansas

A survey of the fishes of the Strawberry River in northcentral Arkansas was made between August 1967 and November 1973. Field collections, literature records and museum specimens showed the ichthyofauna of the Strawberry River to be made up of 95 species distributed among 17 families. Two erroneous records are deleted. One subspecies, Etheostoma spectabile fragi,, is endemic to the river. Records of Notropis fumeus, Etheostotna nigrum, Etheostoma proeliare and Percina sciera represent extensions of previously known ranges within the state

Assessing Photoreceptor Structure Associated with Ellipsoid Zone Disruptions Visualized with Optical Coherence Tomography

Purpose: To compare images of photoreceptor layer disruptions obtained with optical coherence tomography (OCT) and adaptive optics scanning light ophthalmoscopy (AOSLO) in a variety of pathologic states.Methods: Five subjects with photoreceptor ellipsoid zone disruption as per OCT and clinical diagnoses of closed-globe blunt ocular trauma (n = 2), macular telangiectasia type 2 (n = 1), blue-cone monochromacy (n = 1), or cone-rod dystrophy (n = 1) were included. Images were acquired within and around photoreceptor lesions using spectral domain OCT, confocal AOSLO, and split-detector AOSLO.Results: There were substantial differences in the extent and appearance of the photoreceptor mosaic as revealed by confocal AOSLO, split-detector AOSLO, and spectral domain OCT en face view of the ellipsoid zone.Conclusion: Clinically available spectral domain OCT, viewed en face or as B-scan, may lead to misinterpretation of photoreceptor anatomy in a variety of diseases and injuries. This was demonstrated using split-detector AOSLO to reveal substantial populations of photoreceptors in areas of no, low, or ambiguous ellipsoid zone reflectivity with en face OCT and confocal AOSLO. Although it is unclear if these photoreceptors are functional, their presence offers hope for therapeutic strategies aimed at preserving or restoring photoreceptor function

The Epistemic Dimensions of Moral Responsibility and Respect

What epistemic conditions must one satisfy to be morally responsible for an action or attitude? A common worry is that robust epistemic requirements would have disastrous implications for our responsibility attributing practices: we would be unable to make epistemically justified responsibility attributions, or we would be licensed to disrespectfully excuse agents for their sincerely held beliefs. Those more optimistic about robust epistemic requirements inadvertently make them too demanding to explain the moral successes of ordinary agents. The present project shows how both the pessimists and optimists rely on instructively mistaken assumptions in epistemology, ethics, and action theory, and it culminates in a theoretical framework for responsibility for right action (or moral worth) from which well-motivated and unproblematic epistemic requirements fall out. A right action is morally worthy, I argue, just to the extent that it is explained by a reliable tie to the right that is secured through the influence one’s values have (perhaps unreflectively) on one’s informational access and processing. This Value-Secured Reliability framework has wide-reaching import and readily extends to a further variety of moral success: respect
