AKEROYD, J. R. & WALTERS, S. M. 1987. Flora Europaea: the background to the revision of Volume One. Flora Europaea, published 1964-80, is a synthetic catalogue of Europe's vascular plants. Its publication has provided a relatively stable taxonomic and nomenclatural framework for the study of the flora of the continent, and has stimulated much further research and publication. The revision of the first volume of Flora Europaea, at Reading University, has been necessary in order to accommodate new information, to satisfy the continued demand for a complete Flora of Europe, and to update the original text. The revision is being carried out in cooperation with other European and Mediterranean floristic projects. 相似文献

Recent spectacular advances in the technologies and strategies for DNA sequencing have profoundly accelerated the detailed analysis of genomes from myriad organisms. The past few years alone have seen the publication of near-complete or draft versions of the genome sequence of several well-studied, multicellular organisms - most notably, the human. As well as providing data of fundamental biological significance, these landmark accomplishments have yielded important strategic insights that are guiding current and future genome-sequencing projects. 相似文献

Legume systematists have been making great progress in understanding evolutionary relationships within the Leguminosae (Fabaceae), the third largest family of flowering plants. As the phylogenetic picture has become clearer, so too has the need for a revised classification of the family. The organization of the family into three subfamilies and 42 tribes is outdated and evolutionarily misleading. The three traditionally recognized subfamilies, Caesalpinioideae, Mimosoideae, and Papilionoideae, do not adequately represent relationships within the family. The occasion of the Sixth International Legume Conference in Johannesburg, South Africa in January 2013, with its theme “Towards a new classification system for legumes,” provided the impetus to move forward with developing a new classification. A draft classification, based on current phylogenetic results and a set of principles and guidelines, was prepared in advance of the conference as the basis for discussion. The principles, guidelines, and draft classification were presented and debated at the conference. The objectives of the discussion were to develop consensus on the principles that should guide the development of the classification, to discuss the draft classification's strengths and weaknesses and make proposals for its revision, and identify and prioritize phylogenetic deficiencies that must be resolved before the classification could be published. This paper describes the collaborative process by a large group of legume systematists, publishing under the name Legume Phylogeny Working Group, to develop a new phylogenetic classification system for the Leguminosae. The goals of this paper are to inform the broader legume community, and others, of the need for a revised classification, and spell out clearly what the alternatives and challenges are for a new classification system for the family. 相似文献

Mass customization (MC) as a business strategy is designed to simultaneously compete on two rival competitive priorities—the price and customization level of a product. MC academics and experts have gone a step further. They suggest that MC is a unique strategy whose implementation promises across-the-board improvement in all four of the competitive priorities (price, quality, flexibility, and speed) simultaneously. Its growing adoption by businesses in recent years, the steep rise in success stories associated with MC, and the voluminous body of publications in a short period of its existence have created a need to study the directions, trends, application potential, and research strategies embedded in these publications. Accordingly, this paper studies and analyzes the trends and directions of the research published in 1,124 MC publications that have appeared in journals and magazines since the inception of the term mass customization in 1987 by Stan Davis in his classic book Future Perfect. Statistical trend analyses are conducted to study the vitality and health of the field of MC using number of publications and number of publication outlets and their respective trends. The publication outlet data conform to an S curve, establishing maturity of the MC field. The publication data show that the MC field has passed through four stages of growth: incubation or slow (1987–1992), exponential (1993–2003), stable and matured (2003–2005). There is a slight dip in 2006 in terms of publication outlets; there are, however, confirmatory factors that indicate that the dip in 2006 may be an outlier. This paper also suggests developing a clear understanding of the value and type of research embodied in MC publications through three types of taxonomic analyses. The frameworks for all three taxonomies are set forth, two of which have been previously employed in other areas of OR/MS (Reisman and Kirschnik, Oper Res 42(4):577–588, 1994; Oper Res 43(5):731–740, 1995): The first taxonomic framework first classifies the paper as a theory paper or an application paper. At the second stage, the application content of the publication is determined based on a five-point scale ranging from simple modeling of the real world to bona fide real-world application. The second taxonomic framework suggests usage of a taxonomy comprised of seven distinct types of research strategies. The former analysis provides important information about the application worthiness of the MC publications and hence their usefulness to the real world. The second analysis provides information about the type of research strategies used by MC researchers, which, in turn, allows drawing conclusions about the quality and rigor of such research. The third taxonomic framework suggested recommends classification of all publications among multi-level containers based on the disciplines that intersect with MC and their branches. 相似文献
