Wate. store. as part of the.land surface.is lost to e.apotranspiration and runoff on diffe.e.t time.scale., and the.partitioning be.we.n the.e.time.scale. is important for mode.ing soil wate. in a climate.mode.. Diffe.e.t time.scale. are.impose. on e.apotranspiration primarily be.ause.it is de.ive. from diffe.e.t re.e.voirs with diffe.e.t storage.capacitie., from the.ve.y rapid e.aporation of canopy store. to the.slow re.oval by transpiration of rooting zone.soil moisture. Runoff like.ise.range. in time.scale.from rapid surface.te.ms to the.slowe. base.flow. The.longe.t time.scale.losse. of wate. de.e.mine.the.slow variation of soil moisture.and he.ce.the.longe. time.scale.e.fe.ts of soil moisture.on pre.ipitation. This pape. shows with a simple.analysis how shifting the.partitioning of e.apotranspiration be.we.n the.diffe.e.t re.e.voirs affe.ts the.variability of soil moisture.and pre.ipitation. In particular, it is conclude. that a shift to shorte. time.scale.re.e.voirs shifts the.variance.of pre.ipitation from that which is pote.tially pre.ictable.to unpre.ictable.

Background: Antibiotics are.fre.ue.tly pre.cribe. for uppe. acute.re.piratory tract infe.tions (ARI) in the.e.e.ge.cy de.artme.t. To re.uce.inappropriate.ove.pre.cribing, it is ne.e.sary to unde.stand factors influe.cing physicians’ de.isions to pre.cribe.antibiotics. Obje.tive. Analyze.the.judgme.t policie. of e.e.ge.cy physicians to de.e.mine.factors pre.icting antibiotic use. De.ign: Pape. case.vigne.te.study. Participants: 104 e.e.ge.cy physicians from Wisconsin. Me.sure.e.ts: We.use. judgme.t analysis to de.ive.the.policie. of 104 e.e.ge.cy physicians from the.r re.ponse. to 20 case.vigne.te.. We.de.igne. the.case. such that e.ch physician’s use.of clinical findings and patie.t factors could be.infe.re. from the.de.isions the. made.about e.ch case. Findings we.e.compare. to primary care.practitione.s (PCPs) in Colorado re.ponding to the.same.pape. case. to e.amine.diffe.e.ce. in factors influe.cing pre.cribing among the.two groups. Re.ults: The.e.e.ge.cy physicians said the. would pre.cribe.an antibiotic (ye./no) in 51.4% of case. compare. with 44.5% in the.Colorado study. The.majority of e.e.ge.cy physicians gave.the.gre.te.t we.ght to duration of illne.s (51%), followe. by te.pe.ature.(20%) and cough (12%). Conclusions: The.e.e.e.ge.cy physicians pre.cribe. antibiotics more.fre.ue.tly than the.Colorado PCPs. The.e.was little.diffe.e.ce.in how clinical findings we.e.we.ghte., sugge.ting this was not the.source.of the.highe. pre.cription rate.among the.e.e.ge.cy physicians. The.conside.able.e.phasis on duration of illne.s sugge.ts that this would be.a productive.are. for e.ucational e.forts to re.uce.antibiotic pre.cribing for ARI in the.e.e.ge.cy de.artme.t.
