bone chisel. Intriguing in the latter context is the mention of "instrumentists" (organikoi) (e.g. pp. 60ff, 158), whose activities as technicians were sometimes the subject of criticism by medical writers, since, on occasion, their quest to perfect surgical tools seems to have taken precedence over the best interest of the patient. Their inventiveness may, perhaps, be seen, too, in certain par...

During a 1-year period, we sampled stream water total phosphorus (TP) concentrations daily and soluble reactive phosphorus (SRP) concentrations weekly in four Seattle area streams spanning a gradient of forested to urban-dominated land cover. The objective of this study was to develop time series models describing stream water phosphorus concentration dependence on seasonal variation in stream ...

In a questionnaire study the effects of discourse structural information on resolving inter-sentential anaphora were investigated. The Right Frontier Constraint, first proposed by Polanyi (1988), states that potential antecedents of an anaphor that are placed at the right frontier of a discourse unit can be accessed more easily than antecedents that are placed somewhere else. Participants (N=36...

It is generally assumed that ellipsis requires certain parallelism between the clause containing the ellips is and some antecedent clause. We argue that the parallelism requirement generated by ellipsis must be applied in accordance with discourse structure: a matching antecedent clause must be found that locally c-commands the clause containing the ellipsis in the discourse tree. We show that ...

The distributed lag model (DLM), used most prominently in air pollution studies, finds application wherever the effect of a covariate is delayed and distributed through time. We specify modified formulations of DLMs to provide computationally attractive, flexible varying-coefficient models that are applicable in any setting in which lagged covariates are regressed on a time-dependent response. ...

Rainfall effects on beach water quality in southern California are large enough that county health departments typically issue warnings for the public to avoid recreational water contact for 3 days following a storm. To enhance the scientific foundation for these preemptive public health warnings, we examined the relationship between rainfall and beach indicator bacteria concentrations using 5 ...

To assess the drug-behavior interaction effects with an 8-year-old boy wih attention deficit hyperactivity disorder, common classroom antecedent (e.g., seating arrangement) and consequent (e.g., peer prompts) stimuli were alternated within a school day while drug conditions (methylphenidate vs. placebo) were alternated across days. The results suggested that peer attention maintained disruptive...

[Purpose] In the present study, we investigated the effect of antecedent exercise on functional recovery and brain-derived neurotrophic factor (BDNF) expression following focal cerebral ischemia injury. [Subjects] The rat middle cerebral artery occlusion (MCAO) model was employed. Adult male Sprague-Dawley rats were randomly divided into 4 groups. Group I included untreated normal rats (n=10); ...

Hydrologic response in natural catchments is controlled by a set of complex interactions between storm properties, basin characteristics and antecedent wetness conditions. This study investigates the transient runoff response to spatially-uniform storms of varying properties using a distributed model of the coupled surface-subsurface sys5 tem, which treats heterogeneities in topography, soils a...

Although plot-scale erosion experiments are numerous, there few studies on constructed landforms. This limits the understanding of their long-term stability, which is especially important for planning mined land rehabilitation. The objective this study was to gain insight into processes in a 30 × m trial plot mine waste rock dump tropical northern Australia. relationships between rainfall, runo...
