Phylogenetic relationships among 40 extant species of rodents, with an emphasis on the taxonomic sampling of Muridae and Dipodidae, were studied using sequences of the nuclear protein-coding gene LCAT (lecithin cholesterol acyl transferase). Analysis of 804 bp from the exonic regions of LCAT confirmed many traditional groupings in and around Muridae. A strong support was found for the families Muridae (represented by 29 species) and Dipodidae (5 species). Compared with Sciuridae, Gliridae, and Caviomorpha, the Dipodidae family appeared the closest relative of Muridae, confirming the suprafamilial Myodonta concept. Within the speciose family Muridae, the first branching leads to the fossorial Spalacinae and semifossorial Rhyzomyinae. The remaining components of Muridae appear as a polytomy from which are issued Sigmodontinae, Calomyscinae, Arvicolinae, Cricetinae, Mystromyinae, Nesomyinae, and some Dendromurinae (Steatomys and Dendromus). This phylogeny is interpreted as the result of a bushlike radiation at the end of the early Miocene, leading to emergence of most living subfamilies. The separation between three additional taxa, Murinae, Gerbillinae, and "Acomyinae" (which comprises the genera Acomys, Deomys, Uranomys, and Lophuromys), has occurred more recently from a common ancestor issued from the main basal radiation. As previously shown by other molecular studies, the vlei rats, Otomyinae, are nested within Old World Murinae. In the same way, the zokors, Myospalacinae, appear strongly nested within the hamsters, Cricetinae. Finally, we propose a sister group relationship between Malagasy Nesomyinae and south African Mystromyinae. [less ▲]

Research related to the prevention of business failure is surveyed in this paper. More specifically, the evolution of the accounting literature on business failure from a predictive to a preventive perspective is explained. After a clarification of the concept of business failure prevention, the main features of representative studies are presented and analysed. These studies are compared in terms of dynamics of the results proposed, of failure stage(s) studied, of conceptual approach privileged, of research object and of methodology used to obtain results. A typology of the research on business failure prevention is then proposed on the basis of two pertinent differentiating criteria: the dynamics of the contributions and the failure stage(s) taken into consideration. This paper finally stresses current limitations of business failure prevention literature, particularly the need for a consensus on how and why firms fail and the lack of investigation about typical failure profiles and paths. Potentialities for future progress in the field are discussed at the end of the paper. [less ▲]

Considering the fragmented literature dedicated to business failure prevention and considering the need for a unifying conceptual framework on how and why companies fail, the aim of this paper is to gather the findings from the multiple studies focused on the identification of failure factors and of failure paths, in order to propose a unifying model showing the chronological combination of the diverse factors leading a company to bankruptcy. An in-depth analysis of the existing literature and of its limitations leads us to the elaboration of an original integrative model on how and why companies fail. It is founded on a resource-based view of the firm (Wernerfelt, 1984) and it represents the different general phases through which a company goes by in its evolution towards its juridical failure. Moreover it emphasizes the fact that all companies do not necessarily follow the same paths before they disappear (Argenti, 1976). [less ▲]

The Open Source Software industry has been submitted to important changes during the last decade, moving from the initial "libertarian ideology" to a "market economy" in which companies develop a genuine commercial orientation. Based on case studies – six OSS companies –, our exploratory research emphasizes three main business models those enterprises can bring out to provide their products and services and to generate profit from their activities: complexity, closed system, intermediation. Such business models express different positions in relation to the OSS philosophy and highlight the main distinctive resources (Barney, 1991) the companies may mobilise in order to make their clients dependent and to consolidate their competitive advantage.

In this paper we focus on the much debated Butcher-Oemler effect: the increase with redshift of the fraction of blue galaxies in clusters. Considering a representative cluster sample made of seven groups/clusters at z similar to 0.35, we have measured the blue fraction from the cluster core to the cluster outskirts and the field mainly using wide-field Cerro Tololo Inter-American Observatory images. This sample represents a random selection of a volume complete X-ray selected cluster sample, selected so that there is no physical connection with the studied quantity (blue fraction), to minimize observational biases. In order to statistically assess the significance of the Butcher-Oemler effect, we introduce the tools of Bayesian inference. Furthermore, we have modified the blue fraction definition in order to take into account the reduced age of the Universe at higher redshifts, because we should no longer attempt to reject an unphysical universe in which the age of the Universe does depend on redshift, whereas the age of its content does not. We have measured the blue fraction from the cluster centre to the field and we find that the cluster affects the properties of the galaxies up to two virial radii at z similar to 0.35. Data suggest that during the last 3 Gyr no evolution of the blue fraction, from the cluster core to the field value, is seen beyond that needed to account for the varying age with the redshift of the Universe and of its content. The agreement of the radial profiles of the blue fraction at z= 0 and z similar to 0.35 implies that the pattern infall did not change over the last 3 Gyr, or, at least, its variation has no observational effect on the studied quantity.

This paper contains the fully reduced observational data on the Beta Cep star BW Vul, which were obtained in the summer of 1982 during an international campaign at thirteen observatories in the northern hemisphere. Useful measurements were made during a total of 486 hours. All observations have been assigned proper weights and were binned in time intervals of 90 seconds. In this manner the observations were combined into single data points which resulted in about 6000 mean differential measurements. A preliminary ephemeris for 1982 is derived, and a mean lightcurve is given. The results indicate a fair degree of stability in the shape and in the amplitude of the lightcurve. Possible variations exist in the morphology of the stillstand phenomenon. [less ▲]
