Competitive Strategy and Financial Ratios
SSRN Electronic Journal, 2007We examine whether asset turnover and profit margin ratios reflect a firm's competitive strategy. We show the following: (a) the RNOA, asset turnover and profit margins are firm-specific rather than industry-specific, indicating that these ratios provide information on the firm's operating choices.

Competitive Online Approximation of the Optimal Search Ratio
SIAM Journal on Computing, 2004How efficiently can we search an unknown environment for a goal in unknown position? How much would it help if the environment were known? We answer these questions for simple polygons and for general graphs, by providing online search strategies that are as good as the best offline search algorithms, up to a constant factor.

The dynamics of operational sex ratios and competition for mates
Trends in Ecology & Evolution, 1996In sexually reproducing animals, individuals of one sex may have to compete for access to mating partners of the opposite sex. The operational sex ratio (OSR) is central in predicting the intensity of mating competition and which sex is competing for which.

Sex ratio and intrasexual kin competition in mammals
Oecologia, 1985Asymmetries in both intrasexual competition and generation overlap occur in Antechinus (Dasyuridae; Marsupialia). We show that the range of interpopulation variation in the sex ratio of pouch young spans and exceeds the range of sex ratios at birth hitherto recorded from eutherians (Clutton-Brock and Albon 1983). Although postweaning dispersal and male

A ratio measure of interparty competition?
Behavioral Science, 1977Meltz has proposed a ratio measure of interparty competition, Ω, for two-party electoral systems which he claims is completely general. It is maintained that for very reasonable situations of party competition, the Meltz index does not fall in the [0,1] interval and that it is better interpreted as approximating a standard score.

Ratio of Fainess and Competitiveness in Judicial Practice
Prologue: Law Journal, 2021The article is devoted to the study of the question of the ratio of fairness and competitiveness in judicial practice. The purpose of the article is to determine the general and distinctive features of fairness and competitiveness in the legal process, to establish the relationship in judicial practice, and to identify contradictions between them.

A Lower Bound on the Competitive Ratio of Truthful Auctions
2004We study a class of single-round, sealed-bid auctions for a set of identical items. We adopt the worst case competitive framework defined by [6,3] that compares the profit of an auction to that of an optimal single price sale to at least two bidders. In this framework, we give a lower bound of 2.42 (an improvement from the bound of 2 given in [3]) on ...

Tight competitive ratios for parallel disk prefetching and caching
Proceedings of the twentieth annual symposium on Parallelism in algorithms and architectures, 2008We consider the natural extension of the well-known single disk caching problem to the parallel disk I/O model (PDM) [17]. The main challenge is to achieve as much parallelism as possible and avoid I/O bottlenecks. We are given a fast memory (cache) of size M memory blocks along with a request sequence Σ =(b1,b2,...,bn) where each block bi resides on ...
