A review of paleobotanical studies of the Early Eocene Okanagan (Okanogan) Highlands floras of British Columbia, Canada, and Washington, USA

Abstract: The history of plant fossil collecting in the Okanagan (Okanogan) Highlands of British Columbia and northeastern Washington is closely intertwined with the history of geological surveys and mining activities from the 1870s onward. The first descriptions of fossil plants from British Columbia were published in 1870–1920 by J.W. Dawson, G.M. Dawson, and D.P. Penhallow. In the United States, fossil leaves and fish were first recognized at Republic, Washington, by miners in the early 1900s. Many early workers considered these floras to be of Oligocene or Miocene age. C.A. Arnold described Canadian occurrences of conifers and Azolla in the 1950s. Palynological studies in the 1960s by L.V. Hills, G.E. Rouse, and others and those of fossil fish by M.V.H. Wilson in the 1970–1980s provided the framework for paleobotanical research at several key localities. Permineralized plants were first described from the Princeton chert in the 1970s by C.N. Miller, J.F. Basinger, and others, followed by R.A. Stockey and her st...

The phylogeny of the Hydroporinae and classification of the genus Peschetius Guignot, 1942 (Coleoptera: Dytiscidae)

Abstract: The phylogeny of the Hydroporinae is investigated in a cladistic analysis emphasizing placement of the genus Peschetius Guignot, historically placed in the tribe Hydroporini. Sixty-nine adult and larval morphological characters were coded for 61 species of Hydroporinae representing eight of the nine tribes. Cladistic analysis of the data resulted in 396 most parsimonious cladograms (length = 176, CI = 46, RI = 80). The results indicate that the genus Peschetius is the sister group to the tribe Bidessini based mainly on an unambiguous character, the presence of a prominent internal spermathecal spine, and several other more ambiguous or homoplasious characters. The tribe Bidessini is expanded to include the genus Peschetius, and it is formally transferred from the tribe Hydroporini. Other results indicating interesting relationships of tribes and genera within Hydroporinae are also discussed. Results include; 1) a dramatically paraphyletic Hydroporini with Laccornellus Roughley and Wolfe, Canthyporus Zimmermann and Hydrocolus Roughley and Larson in basal positions within the phylogeny, 2) Hydrovatus Motschulsky and Queda Sharp resolved as sister groups and not closely related to Methlini van den Branden, 3) support for close relationship of Pachydrus Sharp (Pachydrini Bistrom, Nilsson and Wewalka) with Hyphydrini Sharp, 4) paraphyly of Hygrotus Stephens sensu lato with the relationship H. (Coelambus) Thomson + (Hygrotus sensus stricto + Hydrovatini)) suggesting recognition of Coelambus and Hygrotus as separate genera, 5) close relationship between the Australian genera of Hydroporini and Hyphydrini and 6) the nesting of Vatellini within a group of Hydroporini.

A generalization of a third irreducibility theorem of I. Schur

Abstract: is irreducible over the rationals. I. Schur (in [10]) obtained this result in the special case that an = ±1 and used it to establish the irreducibility of H2n(x) where Hm(x) is the mth Hermite polynomial. The result stated above is best possible in the sense that, for any integer n > 1, if |an| = 2n − 1, then there are values of a0, a1, . . . , an with a0 = ±1 such that the polynomial f(x) in (1) is reducible. Indeed, if |an| = 2n − 1 and a0 = ±1, then one can take an−2 = an−3 = · · · = a1 = 0 and an−1 to be one of the four numbers ±u2n−2 ± 1 to deduce that f(x) is divisible by x2 − 1 (or, if desired, by x2 + 1). There are other examples of reducibility that can occur when |an| = 2n−1. The polynomial f(x) defined by u12f(x) = 11x12 + 1188x8 + 6930x4 + 10395 = 11(x4 + 3)(x8 + 105x4 + 315)

Improving the understanding of BAM technology for real-time decision support

Abstract: Business activity monitoring (BAM) provides real-time access to critical business performance indicators to improve the speed and effectiveness of business operations. Ideally, BAM systems should allow enterprises to improve their operational performance by helping them perceive, understand and respond to events that have a significant impact on their business processes. Despite the fact that most enterprises have pressing needs to improve their operational performance in highly competitive and dynamic business environments, BAM systems have been poorly utilised. This is mainly due to the fact that there are no formal standards which enumerate what specific features BAM systems must include or theoretical models which support comparative analyses between BAM systems. Indeed, selecting a suitable BAM system is a challenge. To improve the ability of enterprises to understand and select a BAM system for their particular decision support needs, a BAM definitional model as well as BAM classification criteria are proposed.

Female drug users and the welfare system: a qualitative exploration

Abstract: In the United States, much of the public views welfare recipients negatively, as unmotivated, as lazy, as chronic drug users, and as exploiters of the system. Yet, despite a large body of sociological literature regarding welfare recipients and their stigmatized social position, there exists a dearth of information from the individuals themselves, most notably from those engaged in drug use. That is, the voices of welfare recipients are largely absent from published sociological research. The link between drug use and public assistance is seen frequently as absolute, though the reasons for this relationship are chiefly unknown. In this paper we present a qualitative analysis that allows for new understandings of the welfare system and of the lives of the female drug users who are publicly seen as unworthy of assistance. Our in-depth interviews demonstrate that welfare dependency and drug use are symptoms of the women's societal position, largely resulting from barriers including a lack of education, few j...
