Radio Frequency Identification (RFID), once a niche technology, is rapidly gaining the attention of retailers as a key enabler in their supply chain. As RFID moves into the mainstream, it is poised to replace the standard barcode as the technology that identifies and tracks products throughout the supply chain. In an attempt to gain competitive advantages, some retailers have begun the transition to RFID while others have been reluctant to embrace it. This study investigates South Korean retailers to identify key organizational characteristics that positively drive the evaluation of RFID. Further, this study assesses the impact one's evaluation has on the adoption and integration of RFID within their respective firm. Results from 278 adopting organizations show organizational needs (Ubiquity and Performance Gaps), perceived factors (Benefits and Cost Savings), and organizational readiness (Financial Resources and Technological Knowledge) have a significant influence on RFID Evaluation; and evaluation impacts its adoption, and integration. © 2010 Elsevier Ltd.

Batting order (i.e., lineup) optimization for professional baseball teams has been analyzed for decades using various models and assumptions. In general, while optimization is useful-even with minimal benefit-it yields only small fractions of a run per game in improvement, mainly due to the interchangeability of most professional baseball players. Youth baseball, on the other hand, is a prime candidate for lineup optimization as it addresses large talent disparities and creates substantial improvements. In addition, a typical youth lineup is comprised of the same batters throughout a season, while this is not even approximately true for most major league teams; thus, finding "a lineup" for a youth team is more meaningful and useful in that sense. Here, the optimal lineup is considered to be the one which produces the highest number of runs per game. A probabilistic algorithm finds this optimal lineup by simulating many games with each possible lineup, allowing for more detailed statistical analysis. In addition, we see how run limits affect game outcomes and how individual players contribute to a team's performance. A study of a major league lineup is used for comparison. Source

Prior investigations have generally failed to confirm or deny the perceptual influence of highfrequency harmonics contained in musical sounds. Embedded within this experiment were two listening tests: one investigating threshold for differences in timbre, and thus, participant ability, and another seeking to find an influence of high-frequency harmonic content on timbre perception. Based on the premise that harmonics out of the range of auditory detection influence the resultant waveform and therefore may alter the percept of a sound's tonal character, this study found no evidence that capable listeners noticed an effect of high-frequency harmonics within a brief complex tone.

This paper examines market cointegration of city-gate and residential natural gas prices. Cointegration of gas prices across different segments of the industry provides evidence that deregulation has resulted into a more integrated, competitive natural gas industry where gas prices converge into a long-run equilibrium. Our results indicate prices further down the distribution line, the final two points of consumption, are cointegrated for a majority of the US states post open access and retail unbundling, although we find little evidence of perfect market integration. The two price series likewise converge to the long-run equilibrium faster post open access and retail unbundling. Results relative to state level unbundling (choice programs) reveal mixed outcomes with a few states without retail unbundling exhibiting market integration while some states with full unbundling exhibiting non-cointegration. © 2010 Elsevier B.V.

The analysis of diverse data sets can yield different phylogenetic estimates that challenge systematists to explain the source of discordance. The mole salamanders (family Ambystomatidae) are a classic example of this phylogenetic conflict. Previous attempts to resolve the ambystomatid species tree using allozymic, morphological, and mitochondrial sequence data have yielded different estimates, making it unclear which data source best approximates ambystomatid phylogeny and which ones yield phylogenetically inaccurate reconstructions. To shed light on this conflict, we present the first multi-locus DNA sequence-based phylogenetic study of the Ambystomatidae. We utilized a range of analyses, including coalescent-based methods of species-tree estimation that account for incomplete lineage sorting within a locus and concordance-based methods that estimate the number of sampled loci that support a particular clade. We repeated these analyses with the removal of individual loci to determine if any locus has a disproportionate effect on our phylogenetic results. Collectively, these results robustly resolved many deep and relatively shallow clades within Ambystoma, including the placement of A. gracile and A. talpoideum as the sister clade to a clade containing all remaining ambystomatids, and the placement of A. maculatum as the sister lineage to all remaining ambystomatids excluding A. gracile and A. talpoideum. Both Bayesian coalescent and concordance methods produced similar results, highlighting strongly supported branches in the species tree. Furthermore, coalescent-based analyses that excluded loci produced overlapping species-tree posterior distributions, suggesting that no particular locus - including mtDNA - disproportionately contributed to our species-tree estimates. Overall, our phylogenetic estimates have greater similarity with previous allozyme and mitochondrial sequence-based phylogenetic estimates. However, intermediate depths of divergence in the ambystomatid species tree remain unresolved, potentially highlighting a region of rapid species radiation or a hard polytomy, which limits our ability to comment on previous morphologically-based taxonomic groups. © 2013.
