Many studies have found that plant invasion can enhance soil organic carbon (SOC) pools, by increasing net primary production (NPP) and/or decreased soil respiration. While most studies have focused on C input, little attention has been paid to plant invasion effects on soil respiration, especially in wetland ecosystems. Our study examined the effects of Spartina alterniflora invasion on soil r...
the study addresses performance control matrix (pcm) to determine service quality items of priority for improvement. most businesses focus on customer satisfaction when undertaking surveys of satisfaction and dissatisfaction, while generally neglecting employee satisfaction. therefore, this study develops an integrated model to improve service quality in taiwanese finance industry employees. a ...
Seagliders, deployed through most of 2005 in the subtropical North Pacific gyre, made measurements of temperature, salinity, and dissolved oxygen to quantify net community production (NCP) at Station A LongTerm Oligotrophic Habitat Assessment (ALOHA) of the Hawaii Ocean Time-series (HOT) using an oxygen mass balance approach. A ‘bowtie’-shaped pattern, 50 km by 50 km in size was repeatedly trav...
Green roof assemblies influence the total roof surface energy balance for a building. The energy balance for a green roof depends mostly on the selection of plants and substrates suitable for the building’s location. This study measured thermal properties of common green roof materials and selected two types of plants and substrates to simulate transient thermal performance of different green r...
This paper identifies a new cost of pay-for-performance incentives when principal and agent may disagree on the optimal course of action. In particular, pay-for-performance gives the agent a reason to disobey the principal, and thus act against his principal’s interests, when the two of them disagree. In other words, high-powered incentives may decrease the agent’s ‘zone of acceptance’ (Simon 1...
The Southern Ocean is of outsized significance to the global oxygen and carbon cycles with relatively poor measurement coverage due to harsh winters and seasonal ice cover. In this study, we use recent advances in the parameterization of air-sea oxygen fluxes to analyze 9 years of oxygen data from a recalibrated Argo oxygen data set and from air-calibrated oxygen floats deployed as part of the ...
OBJECTIVE To investigate risk factors, including reported net use, for Plasmodium infection and anaemia among school children and to explore variations in effects across different malaria ecologies occurring in Kenya. METHODS This study analysed data for 49 975 school children in 480 schools surveyed during a national school malaria survey, 2008-2010. Mixed effects logistic regression was use...
Total gas pressure, oxygen, temperature and salinity were measured at 50m on a mooring at the Hawaii Ocean Time series (HOT) station from January through September of 1997 and 1998 using a gas tension device (GTD) and a conductivity temperature depth and oxygen (CTD-O2) sensor (GTD–CTD-O2 instrument package). Our goal was to evaluate the precision and accuracy of the in situ total gas and oxyge...
On the basis of a low probability insurance experiment with substantial money on the line, we demonstrate that concern is an important driver of willingness to pay (WTP) for insurance when there is ambiguity surrounding the estimate. Concern still plays an important role when probabilities are given precisely. This finding explains why some individuals pay too much and others little for insuran...
Graham, J.L., J.R. Jones, S.B. Jones and T.E. Clevenger. 2006. Spatial and temporal dynamics of microcystin in a Missouri reservoir. Lake and Reserv. Manage. 22(1):59-68. Environmental factors associated with spatiotemporal variation of microcystin (MC) in Mozingo Lake, a Missouri reservoir, were studied during summer 2001, and annual MC trends were characterized from May 2001-May 2002. MC incr...
