Simulated Annealing and Threshold Accepting are two stochastic search algorithms that have been successfully used on a variety of complex and difficult problem sets. Due to their stochastic nature they are not guaranteed to produce the same result for each run. This means that these techniques actually produce a distribution...
The purpose of this study is to fill a critical gap in brand equity literature by proposing and empirically testing a brand equity process model for unfamiliar Asian brands. Cue utilization theory (Easterbrook, 1959) and impression formation theory (Asch, 1946) were integrated to explain how extrinsic and intrinsic cues shown...
Online shopping is one of the fastest growing forms of shopping with sales reaching $141.4 billion in 2004 (Shop.org, 2005). With the tremendous growth of online retailing, and the prevalence of impulse buying today, this study's purpose was to investigate the internal and external factors of impulse buying in an...
The subaerial beach, composed of sand dunes and the foreshore, provides a natural buffer zone between vulnerable land and the dissipation of storm wave energy due to wave breaking. The natural beauty of this region is attractive to people, and as a result, significant investment has been placed in this...
Chemicals must be bioavailable for there to be a potential for exposure and consequent risk to human or environmental health. Passive sampling devices (PSDs) are used to quantify the time-integrated concentration of bioavailable contaminants. We demonstrate that PSDs can be paired with the zebrafish developmental toxicity bioassay to produce site-specific,...
The optimal allocation of buffers in serial production systems is one of the oldest and most researched problems in Industrial Engineering. In general, there are three main approaches to the buffer allocation problem when the objective is to maximize throughput. The first is basically a systematic trial and error procedure...
North American cultivation of Ribes L. may expand as small fruit growers seek species to diversify horticultural crops. The Ribes industry was suppressed for decades out of fear that cultivated black currants and gooseberries would intensify the fungal disease white pine blister rust (WPBR) on five-needle pine (Pinus L. section...
Contaminants can exist in a wide range of states in aqueous environments, especially in surface waters. They can be freely dissolved or associated with dissolved or particulate organic matter depending on their chemical and physical characteristics. The freely dissolved fraction represents the most bioavailable fraction to an organism. These freely...
Genetic variability in natural populations of Douglas-fir was
studied at molecular level by investigating the variations of some
primary gene products, i. e. enzymes. Using the techniques of disc
gel electrophoresis and biochemical staining, the isoenzyme patterns
of leucine aminopeptidase, esterase and glutamate oxaloacetate
transaminase are characterized in young seedlings...
The seasonal distribution of bioavailable organochiorine contaminants in surface
water and the potential environmental factors influencing their bioavailability were
evaluated. The study was carried at the lower Willamette River at Portland Harbor, Oregon
where surface water runoff varied according to season. Bioavailable water concentrations of
DDTs and PCBs were determined...
