Populations of sea urchins often fluctuate greatly in density. The density of sea urchins is usually inversely correlated with the abundance of macrolagae. It is argued that fluctuations in density are a predictable consequence of the unique morphology and physiology of sea urchins. An extraordinary ability to accomodate food Limitation through variations in growth rate means that surv~vorship ...

Introduction: From the beginning several surgical techniques have been invented to treat herniated cervical intervertebral disc. Long term results with well-designed studies have not been evaluated. Variation in Surgical Technique: The surgical techniques have varied with several variable factors and different variables used for evaluation. Postoperative interscapular pain following ACD has var...

Purpose: This paper examined whether naïve listeners could perceive phonetic detail in children's productions of /s/ and /T/, and whether their perception of /s/ and /θ/ could be biased by their belief about the child's overall speech-production ability. Method: In Experiment 1, listeners provided judgments of children's productions of /s/ and /T/ using a visual analog scale (VAS). In Experimen...

With 77 species, the mussel fauna of Virginia is one of the most diverse in the United States. Fifty-four species or ~70% of the state’s mussel fauna occurs in the rivers of the upper Tennessee River basin, especially in the Clinch and Powell rivers of southwestern Virginia. An additional 23 species reside in rivers of the Atlantic Slope, including the Potomac, Rappahannock, York, James and Cho...

Expertise researchers have traditionally shied away from studying the highest levels of achievement in favor of studying basic cognitive processes, such as memory and categorization. In this article, we present a different approach that is focused on capturing superior (expert) performance on representative tasks that reveal the essential characteristics of expertise in a given domain. In domai...

Two studies attempt to determine the causes of poor metacomprehension accuracy, and then, in turn, to identify interventions that circumvent these difficulties to support effective comprehension monitoring performance. The first study explored the cues that both at-risk and typical college readers use as a basis for their metacomprehension judgments in the context of a delayed summarization par...

Background: Having an irregular bedtime (IB) is a prevalent problem in young adults and may be a potential detrimental factor affecting sleep quality. The goal of this study was to explore the effect of an IB on sleep quality, daytime sleepiness, and fatigue of undergraduate students in Taiwan. Methods: In total, 160 students completed the survey which included four parts: the Pittsburg Sleep Q...
