The genome of woodland strawberry ( Fragaria vesca )

Abstract: The woodland strawberry, Fragaria vesca (2n = 2x = 14), is a versatile experimental plant system. This diminutive herbaceous perennial has a small genome (240 Mb), is amenable to genetic transformation and shares substantial sequence identity with the cultivated strawberry (Fragaria × ananassa) and other economically important rosaceous plants. Here we report the draft F. vesca genome, which was sequenced to ×39 coverage using second-generation technology, assembled de novo and then anchored to the genetic linkage map into seven pseudochromosomes. This diploid strawberry sequence lacks the large genome duplications seen in other rosids. Gene prediction modeling identified 34,809 genes, with most being supported by transcriptome mapping. Genes critical to valuable horticultural traits including flavor, nutritional value and flowering time were identified. Macrosyntenic relationships between Fragaria and Prunus predict a hypothetical ancestral Rosaceae genome that had nine chromosomes. New phylogenetic analysis of 154 protein-coding genes suggests that assignment of Populus to Malvidae, rather than Fabidae, is warranted.

A new class of radio pulsars

Abstract: A new class of spun-up radio pulsars with short periods, long apparent ages, and pulsed optical, X-ray, and gamma ray fluxes significantly below those expected for canonical pulsars with similar periods is reported. Scenarios for the formation of such a pulsar, in which a neutron star accretes from a Keplerian accretion disk initially fed by a companion, are discussed. Because of their long spin-down lifetimes, such pulsars would probably be observable if their birth rate exceeded even 10 to the -4th that of the canonical ones. It is proposed that the recently discovered millisecond pulsar 4C21.53 belongs to this class, together with the binaries PSRs 1913+16, 0820+02, and 0655+64, as well as possibly several isolated pulsars such as PSRs 1952+29 and 1804-08.

Fluency: A review of developmental and remedial practices.

Abstract: The authors review theory and research relating to fluency instruction and development. They surveyed the range of definitions for fluency, primary features of fluent reading, and studies that have attempted to improve the fluency of struggling readers. They found that (a) fluency instruction is generally effective, although it is unclear whether this is because of specific instructional features or because it involves children in reading increased amounts of text; (b) assisted approaches seem to be more effective than unassisted approaches; (c) repetitive approaches do not seem to hold a clear advantage over nonrepetitive approaches; and (d) effective fluency instruction moves beyond automatic word recognition to include rhythm and expression, or what linguists refer to as the prosodic features of language. The process of becoming literate can be conceptualized as a series of qualitatively different stages through which learners progress as they become increasingly proficient with print (Chall, 1996b; Harris & Sipay, 1990). One of the primary advances in this process involves the shift from dealing with words on a word-byword basis to a rapid, accurate, and expressive rendering of text. In other words, learners develop such familiarity with print that they achieve fluency in their reading. Fluent reading may underlie or assist in effective engagement with text (LaBerge & Samuels, 1974). The purpose of this article is a review of the literature examining how children move toward fluent reading. It will incorporate both theoretical discussions and practical studies relating to fluency research. Specifically, to accomplish this purpose, we have reviewed the theoretical accounts of reading that include an important role for fluency in the reading process and studies that have attempted to facilitate its development.

Security-control methods for statistical databases: a comparative study

Abstract: This paper considers the problem of providing security to statistical databases against disclosure of confidential information. Security-control methods suggested in the literature are classified into four general approaches: conceptual, query restriction, data perturbation, and output perturbation.Criteria for evaluating the performance of the various security-control methods are identified. Security-control methods that are based on each of the four approaches are discussed, together with their performance with respect to the identified evaluation criteria. A detailed comparative analysis of the most promising methods for protecting dynamic-online statistical databases is also presented.To date no single security-control method prevents both exact and partial disclosures. There are, however, a few perturbation-based methods that prevent exact disclosure and enable the database administrator to exercise "statistical disclosure control." Some of these methods, however introduce bias into query responses or suffer from the 0/1 query-set-size problem (i.e., partial disclosure is possible in case of null query set or a query set of size 1).We recommend directing future research efforts toward developing new methods that prevent exact disclosure and provide statistical-disclosure control, while at the same time do not suffer from the bias problem and the 0/1 query-set-size problem. Furthermore, efforts directed toward developing a bias-correction mechanism and solving the general problem of small query-set-size would help salvage a few of the current perturbation-based methods.

An Examination of Organizational Factors Influencing New Product Success in Internal and Alliance-Based Processes

Abstract: New products provide increased sales, profits, and competitive strength for most organizations. However, nearly 50% of the new products that are introduced each year fail. Organizations thus find themselves in a double bind. On the one hand they must innovate consistently to remain competitive, but on the other hand innovation is risky and expensive. Many organizations are forming business alliances to quicken the pace of and reduce risks associated with innovation. Yet by some estimates, 70% of these alliances fail. Many of the prescriptions for successful alliance management clash with recommendations for effective innovation management. The authors develop testable hypotheses by integrating the new products and alliance literature. A construct—cooperative competency—derived from related concepts of mutual adjustment, absorptive capacity, and relational capability is posited as the key factor affecting new product development success, regardless of whether it is an intra- or interfirm endeavor....
