The following subgenera of Apion Herbst are elevated to generic status: Bothryopteron Wagner (type species: Apion grallarium Sharp); Coelocephiilapion Wagner (type species: Apion bryanti Wagner); Coelopterapion Wagner (type species: Apion testaceum Wagner); Fallapion Kissinger (type species: Apien impunctistriatum Smith); and Stenapion Wagner (type Species: Apion constricticolle Sharp). Twelve areas of apionid rostral sulci and carinae are defined and illustrated. Six new species of Coelooephalapien are described: four similar to C. bryanti, (Wagner): Jumentum (panama and Honduras), kektaon (Belize), pelor (Panama), and schema (panama); and two similar to C. spretissimum (Sharp): adhocum (Mexico) and pigrae (Venezuela). C. pilirostre (Wagner), near bryanti, is redescribed from Mexico and Honduras with neotype designation.
Affinities, diagnoses, and descriptions are provided for two new species of Plusiotis: P. spectabilis from an unknown locality in Central America and P. dianae from Veracruz state in Mexico. Plusiotis spectabilis is described from a single female and is the largest species in the genus (41 mm in length).
An undescribed genus and species of flightless longhorned beetle, Apteralcidion lupierrei new genus, new species, in the subfamily Lamiinae, has been collected from giant thistle, Cirsium subcoriaccum, at high elevations in Costa Rica and Panama. This new taxon appears most-closely related to genera in the tribe Acanthocini.
One hundred forty-five species of caddisflies representing 15 families and 46 genera are reported from Oklahoma. Thirty-nine species are new state records. Families having the greatest species richness were Hydroptilidae (44 species), Leptoceridae (31 species), Hydropsychidae (26 species), and Polycentropodidae (13 species).
Book Review: A comprehensive treatment of the ecology of aquatic insects in one place is needed for both students and researchers. Professor Ward is doing this in two volumes. The first volume covers the biology and habitats, as indicated in the subtitle, of the 13 insect orders that are either entirely aquatic at some stage, or those with some members aquatic at some stage. The second volume will be devoted entirely to the feeding ecology of these aquatic species.
Specific Alaskan and Canadian localities are recorded for the chilopod Scolopocryptops sexspinosus (Say) (Cryptopidae), the only indigenous Nearctic scolopendromorph species occurring north of the lower 48 states. It occurs west of the crest of the Coast Range in British Columbia, extending northward to the southernmost islands of Alaska, and is recorded for the first time from eastern Canada, from Niagara Gorge, Ontario. Reports of S. rubiginosus Koch from southern Alaska are based on a misidentification of S. sexspinosus, and records from the north-central United States are too distant from the international border for it to be plausible for Manitoba and western Ontario. This centipede does not occur along the Pacific Coast and is improbable for any other part of Canada.
Vincent Golia, Delray Beach, Florida, collected a single female specimen of the tamarind seed beetle, Caryedon serratus, in an orange grove near Homestead. This is the first record of this bruchid for continental United States although the species is recorded from the Hawaiian Islands, and is often intercepted during port inspections.
New records of the xystodesmid diplopod Stenodesmus tuobitus (Chamberlin) extend its range and those of the family and suborder Chelodesmidea into southwestern New Mexico, west of the Rio Grande. They confirm that it inhabits arid juniper environments at relatively low elevations as well as moist deciduous fir forests at high elevations, thereby lending credence to past records from the former habitat in Lincoln County. Discovery of the milliped in neighboring mountain ranges to the north and west is now likely, with the distant possibility that it may occur in eastern Arizona.
Ommatius fimbriatus and O. subtus are based upon four specimens embedded in Dominican amber from the El Mamey Formation in the Dominican Republic. The amber is from the Lower Oligocene - Upper Eocene, originating between 25 and 40 million years ago. The specimens are the first reported fossils of Ommatius. Both species are described and compared with modern species. Significant characters are illustrated and/or photographed.
A brief account of the present state of weevil taxonomy is followed by a detailed study of certain structures used in their classification, namely the venter, abdominal tergites, sternite 8 of the male, apex of the hind tibia and deciduous mandibular processes. A key to some 50 families and subfamilies of Curculionoidea is followed by a list of family-group taxa. The following changes are made: Brachyceridae, Erirhinidae. Cryptolnryngidae und Raymondionymidae are promoted to family rank from Curculiollidne; Antliarhininae is demoted to a subfamily of Brentidae, and Allocoryninae to a subfamily of Oxycorynidne; Coptonotini is demoted to a tribe of Curculionidue Scolytinae; Carinae, sufam. n. is erected for Car Blackburn (genus incertae sedis) in Belidae; Dinomor'phini is demoted to a tribe of Molytinae and Brachyccropsidinae is revived from synonymy with Dinomorphinae (Curclliionidae); Urachyderini, Eremnini, Otiorhynchini and Sitonini are demoted to tribes of Entiminue; Desmidophorinae is transferred from Brentidae to Brachyccridae, Ocladiini is promoted to a tribe of Desmidophorinae (from Curculionidae-Cryptorhynchinae); Campyloseelini (including Phaenomerina) is transferred from Rhynchophoridae to Curculionidae-Zygopinae; Carphodicticinae is promoted to subfamily rank and transferred from Curculionidae-Scolytinae to Platypodidae; Perieges; Schönherr is transferred from Curculionidae-Thecesterninae to Cryptoiaryngidae and Agriochaeta Pascoe from Cryptorhynchinae to Hyperinae (Curculionidae); Schadlarius Wood and Mecopelmus Blackman are transferred from Coptonotidae to Platypodidae.
The theoretical concept of the biological species and the multidimensional species category, as currently applied by a majority of ornithologists and by many other biologists, replaced the typological-morphological species concept during the first half of this century and became a central tenet of the synthetic theory of evolution. The concept of biospecies is a 'horizontal' concept referring to contemporary reproductive communities at any particular period, e.g. the Recent period or any other time level of the geological past. Historical 'species' concepts as applied by cladists and palaeontologists refer to artificially delimited portions of 'vertical' phyletic lineages for which the application of the term 'species' causes severe problems. Discussions would be simplified if the concept and term 'species' was to be restricted to cross sections of phyletic lineages at any time level and a separate taxonomy outside the Linnaean system of genera and species was to be conceived to deal with phyletic lineages. Under each of the theoretical species concepts, species taxa are assigned broadly to intermediate or narrowly defined taxonomic species categories. Ornithologists of the 19th century applied morphological species concepts, emphasizing morphological character differences between species (rather than distinctness) and the fertility of con specific individuals (rather than the isolation from non-conspecific populations). Nearly all leading museum ornithologists in 19th-century Europe delineated monotypic Linnaean species, whereas the explorer-naturalists of the Gloger-Middendorff school (including Panas, Faber, Gloger, Nordmann, Middendorff, Schrenck, Radde, as well as Schlegel and Blasius) delimited widely circumscribed species taxa. Their researches in the vast territories of eastern Europe, Siberia and the Far East from the late 18th century to the 1880s and, in particular, their rich specimen material, demonstrated direct intergradation of many taxa (geographical varieties) of birds, thus revealing the conspecific nature of numerous narrowly conceived morphospecies previously described by museum workers. The ornithologists of the Gloger-Middendorff school also studied several conspicuous phenomena of geographical character variation in birds (and mammals) across Eurasia, especially plumage colouration (and pelage) and body size, but none of them was an evolutionist. They an adhered to a typological-creationist theoretical species concept. During the late 19th century, the museum specialists' taxonomic notion of narrow morphospecies dominated systematic ornithology in Europe, overtaking the work of the naturalists of the Gloger-Middendorff school, which fell into oblivion. The ornithologists of the Bairdian school in North America (Baird, Coues, Allen, Ridgway) further developed the concept of subspecies after the 1850s and especially from the 1870s onward. Their views were fully in accord with Darwin's theories of evolution' thus they defined the subspecies in a somewhat simplified manner as 'nascent species': These ornithologists were able to base their studies on collections of extensive specimen material which they had obtained during a series of exploring expeditions across the North American continent. Their studies led to the discovery of many aspects of both individual and geographic variation in birds. There are interesting historical similarities between the coinciding taxonomic interpretations and the comparable application of fairly broad limits of morphospecies by the North American ornithologists and the earlier exploring ornithologists in Europe, arrived at Independently by these, research groups, The study of specimens in 'series' (,suites'), beginninng with the naturalists of the Gloger-Middendorff school and, in particular, with the naturalists of the Bairdian school in North America, eventually led to the overcoming of the prevating typological view of variation and the development of 'population thinking'. Influenced by the work of Henry Seebohm in Britain and that of the North American ornithologists, Hartert in England and Kleinschmidt in Germany jointly succeeded in overcoming the strong opposition of the leadi.ng ornithologists in Europe during the 1890s and early 19008 and introduced a concept which soon developed into the biological species concept through the work of Stresemann, Rensch, and in particular, Ernst Mayr. Hopefully, ornithologists will continue the study of taxa at low, intermediate and high levels of microtaxonomic differentiation and will identify the subspecies groups, biological species and the biogeographical species in the world's avifaunas. Cladistic analyses will provide historical {'vertical'} overviews of phyletic lineages at different taxonomic levels.
Speakers of various Southern german dialects may be heard to use two syntactic variants of subordinate clauses which are represented by the following Swabian examples: (1) daß er den net will komme lasse (2) daß er den net komme lasse will Of these two variants of the three-element verbal complex, only the non-dialect counterpart of (2) is accepted as standard modern written German: (3) daß er ihn nicht kommen lassen will In earlier periods of the German language, however, both variants were used by authors of written texts.
Classical mutagenesis
(1992)
Classical genetic analyses require the presence of at least two different alleles per locus. Until the mid 1920's for the different alleles the investigators had to rely on spontaneous mutations. Since then mutagenic agents (mutagens) became available and these discoveries greatly enhanced the power of genetic analyses. Mutation is defined here as a heritable chemical alteration within the gene or the mutation process bringing about the change. Mutant is the individual (cell) containing the mutation. Point mutations are assumed to be free of loss, gain or rearrangement within the nucleotide sequence. Fonvard mutations are changes from the wild type allele (the allele predominant in wild populations) to a new allele, and the reverse process is backmutation. The frequency o/mutation per locus per generation (mutation rate) must be distinguished from mutant frequency, indicating simply the number of mutants in a population. Mutation in the broad sense involves also hereditary changes in chromosome number (polyploidy and aneuploidy) and chromosome structure, visible through the light microscope. The latter types are frequently called chromosomal aberrations. Arabidopsis, without further qualifications, in this context, will refer to Arabidopsis thaliana (L.) Heynh. in its diploid form (2n = 10). This species has three genomes, the nuclear, plastidic and the mitochondrial. Its nuclear genome (n = 5) is the smallest among higher plants (Leutweiler et al., 1984), containing about 0.7 - 1 x 108 bp, and redundancy is very low (Meyerowitz and Pruitt, 1985). The plastid genome is about the same size as that of the mcYority of higher plants, ca. 150 kb. The size of the mitochondrial genome is ca. 400 kb. Arabidopsis is an excellent tool for genetics and its critical features and known mutants have been reviewed (R&Iei , 1970, 1975a,b; Kranz, 1978; Meyerowitz and Pruitt, 1984; Meyerowitz, 1987, 1989; Estelle and Somerville, 1986; Bowman et al., 1988).
The study adressed 4 basic issues: (1) What are the substantive contents of human values? (2) Can we identify a comprehensive set of values? (3) To what extent is the meaning of particular values equivalent for different groups of people? (4) How are the relations among different values structured? These issues required resolution before the antecedents and consequences of value priorities, or cross-cultural differences in such priorities, could be studied effectively. Substantial progress has been made toward resolving each of these issues.
When in 1934, Robert BLEICHSTEINER published the Caucasian language specimina contained in the "travel book" of the 17th century Turkish writer Evliya Çelebi , he was struck by the amount of reliability he found in Evliya’s notations: "(Die Sprachproben) sind, von einzelnen Mißverständnissen abgesehen, und wenn man die falschen Punktierungen und Irrtümer der Kopisten abrechnet, außerordentlich gut, ja zuweilen mit einem gewissen phonetischen Geschick wiedergegeben, was der Auffassungsgabe und dem Eifer Evliyas ein hohes Zeugnis ausstellt. Man muß bedenken, wie schwer das arabische Alphabet, ohne weitere Unterscheidungszeichen, wie sie die islamischen Kaukasusvölker anwenden, die verwickelten, oft über 70 verschiedene Phoneme umfassenden Lautsysteme wiederzugeben imstande ist. Wenn trotzdem die Entzifferung der Sprachproben zum größten Teil geglückt ist, so muß man der ungewöhnlichen Begabung des türkischen Reisenden und Gelehrten schrankenlose Bewunderung zollen" (85). ...
The paper focuses on business negotiation in settings in which participants from different mothertongue backgrounds choose French, English andfor German as one of their languages of communication. A general scheme of the action-pattem of buying and selling will be sketched out which allows us to analyze specific Courses of verbal actions according ta their communicative functions within the negotiation process. In particular, the discourse of business communication is to be specified as a decision making process on the part of the buyer which is executed in a step-by-step order, and which is Open to the application of a bundle of the seller's strategies, tactics, and communicative techniques. In international negotiations, effects of unobserved miscommunication are, among others, far-stretched communicative circles, prolongation of negotiation time, non-functional explanations and several other repetitive structures. 1.

Crépin (1891) arranged 55 species of Rosa into 15 sections. Three of those sections contain taxa native to the British Isles, and members of several further sections have been reported as naturelized. In the discussion below, accepted names are shown in bold, while rejected names are given in italics.
The properties of nuclear matter are studied in the framework of quantum hadrodynamics. Assuming an ω-meson field, periodic in space, a self-consistent set of equations is derived in the mean-field approximation for the description of nucleons interacting via σ-meson and ω-meson fields. Solutions of these self-consistent equations have been found: The baryon density is constant in space, however, the baryon current density is periodic. This high density phase of nuclear matter can be produced by anisotropic external pressure, occurring, e.g., in relativistic heavy ion reactions. The self-consistent fields developing beyond the instability limit have a special screw symmetry. In the presence of such an ω field, the energy spectrum of the relativistic nucleons exhibits allowed and forbidden bands, similar to the energy spectrum of the electrons in solids.
We investigate the production of heavy quarks in continuum and bound states in nuclear collisions. Creation rates for free bb and tt quark pairs and for bottomonium and toponium in the ground state are computed at energies of the BNL Relativistic Heavy Ion Collider, CERN Large Hadron Collider (LHC), and Superconducting Super Collider. Central and peripheral heavy-ion collisions are discussed. For top-quark creation we assumed a mass range of 90≤mt≤250 GeV. The creation rate for top quarks in peripheral collisions is estimated to be by a factor 40 to 130 smaller compared with corresponding central collisions. For mt=130 GeV we calculated a creation rate of about 4760 top-quark pairs per day at the LHC (3.5 TeV/nucleon) for Pb-Pb collisions.
We discuss the multiplicity distribution of electron-positron pairs created in the strong electromagnetic fields of ultrarelativistic heavy-ion transits. Based on nonperturbative expressions for the N-pair creation amplitudes, the Poisson distribution is derived by neglecting interference terms. The source of unitarity violation is identified in the vacuum-to-vacuum amplitude, and a perturbative expression for the mean number of pairs is given.
Relativistic heavy ion collisions constitute a prolific source of hyperons: tens of hyperons per event are predicted at energies E≥10 GeV/nucleon, providing a scenario for the formation of metastable exotic multihypernuclear objects. They may exhibit exceptional properties: bound neutral (e.g., 4M2Λ2n, 10M2Λ8n, pure Λ droplets, 8Λ) and even negatively charged composites objects with positive baryon number (e.g., 4M2Σ-2n, 6M2Λ2Ξ-2n) could be formed in rare events. Such negative nuclei can easily be identified in a magnetic spectrometer. They could be considerably more abundant than antinuclei of the same A. We use the relativistic meson-baryon field theory—which gives an excellent description of normal nuclear and single-Λ hypernuclear properties—to calculate the rich spectrum of such exotic objects, their stability, and their structure. We also find solutions for a large variety of bound short-lived nuclei (e.g., 8M2Λ,2Σ-2p2n), which may decay strongly via formation of cascade (Ξ) particles. Multi-Ξ hypernuclei are also evaluated. A variety of potential candidates for such metastable exotic nuclei is presented. It turns out that the properties of such exotic multihypernuclear objects reveal quite similar features as the strangelet proposed as a unique signature for quark-gluon plasma formation in heavy ion collisions.
A quasiclassical Pauli potential is used to simulate the Fermi motion of nucleons in a molecular dynamical simulation of heavy ion collisions. The thermostatic properties of a Fermi gas with and without interactions are presented. The inclusion of this Pauli potential into the quantum molecular dynamics (QMD) approach yields a model with well defined fermionic ground states, which is therefore also able to give the excitation energies of the emitted fragments. The deexcitation mechanisms (particle evaporation and multifragmentation) of the new model are investigated. The dynamics of the QMD with Pauli potential is tested by a wide range of comparisons of calculated and experimental double-differential cross sections for inclusive p-induced reactions at incident energies of 80 to 160 MeV. Results at 256 and 800 MeV incident proton energy are presented as predictions for completed experiments which are as yet unpublished.
Stopping power and thermalization in relativistic heavy ion collisions is investigated employing the quantum molecular dynamics approach. For heavy systems stopping of the incoming nuclei is predicted, independent of the energy. The influence of the quantum effects and their increasing importance at low energies, is demonstrated by inspection of the mean free path of the nucleons and the n-n collision number. Classical models, which neglect these effects, overestimate the stopping and the thermalization as well as the collective flow and squeeze out. The sensitivity of the transverse and longitudinal momentum transfer to the in-medium cross section and to the pressure is investigated.
Experimental results are presented on the charge, velocity, and angular distributions of intermediate mass fragments (IMFs) for the reaction Fe+Au at bombarding energies of 50 and 100 MeV/nucleon. Results are compared to the quantum molecular dynamics (QMD) model and a modified QMD which includes a Pauli potential and follows the subsequent statistical decay of excited reaction products. The more complete model gives a good representation of the data and suggests that the major source of IMFs at large angles is due to multifragmentation of the target residue.
Strong correlations between baryon stopping in the projectile rapidity hemisphere and target excitation have been found in the light-ion-induced reactions at the BNL Alternating Gradient Synchrotron (AGS) (E814 group). Results in the framework of the relativistic molecular dynamics approach (RQMD) describe recent E814 data quite well. We discuss the RQMD results together with proton and pion data from the E802 group near midrapidity. They have raised the question of whether partial transparency could be seen in these experiments. The RQMD results indicate strong transverse baryon flow in central Si+Au collisions after the projectile has been stopped in the target.
We present a calculation of antiproton yields in Si+Al and Si+Au collisions at 14.5A GeV in the framework of the relativistic quantum molecular dynamics approach (RQMD). Multistep processes lead to the formation of high-mass flux tubes. Their decay dominates the initial antibaryon yield. However, the subsequent annihilation in the surrounding baryon-rich matter suppresses the antiproton yield considerably: Two-thirds of all antibaryons are annihilated even for the light Si+Al system. Comparisons with preliminary data of the E802 experiment support this analysis.
By replacing the irises in an electron linac by a slit one gets a structure capable of focussing/defocussing an electron beam (rf-quadrupoles). Therefore one can think of a combination of rf- and conventional magnetic quadrupoles for transversal focussing in linear-colliders. Furthermore they can meet the demands of BNS-damping without initial energy spread. Considering multibunch-operation of a collider, the long-range wake behaviour of this kind of structure has to be investigated. A three-cell structure has been built and investigated for dipole-type transversal long-range wakes. The experimental results are compared to numerical simulations done with MAFIA.
Determination of field strength and quality factor of heavily HOM damped accelerator cavities
(1992)
Two methods of of measuring field strength in accelerator cavities, heavily damped with respect to higher order modes (HOM), are presented. From the results of the field measurements the coupling (damping) factor and thus the quality factor of the damped resonator can be derived. Measurements of a pillbox resonator with heavily damped TM110-mode (Q < 20) demonstrate the usefulness of the techniques presented, even in this extreme range.
The energy dependence of rapidity distributions and flow effects was studied in central Ar+Pb collisions at 400, 800, and 1800 MeV/nucleon using a streamer chamber. Rapidity distributions for proton and pions are found to have a Gaussian shape whereas those for deuterons exhibit a two-peak structure at the two higher energies. The average in-plane transverse momentum per/nucleon and per/event shows saturation of flow around 800 MeV/nucleon for this asymmetric system. The aspect ratio of the sphericity tensor is closely correlated with the flow angle. This correlation appears to be independent of beam energy. The number of participating nucleons in central collisions varies from 213 at 400 to 135 at 1800 MeV/nucleon indicating that at the lowest energy almost the entire target nucleus participates in the collision.
The general subset sum problem is NP-complete. However, there are two algorithms, one due to Brickell and the other to Lagarias and Odlyzko, which in polynomial time solve almost all subset sum problems of sufficiently low density. Both methods rely on basis reduction algorithms to find short nonzero vectors in special lattices. The Lagarias-Odlyzko algorithm would solve almost all subset sum problems of density < 0.6463 . . . in polynomial time if it could invoke a polynomial-time algorithm for finding the shortest non-zero vector in a lattice. This paper presents two modifications of that algorithm, either one of which would solve almost all problems of density < 0.9408 . . . if it could find shortest non-zero vectors in lattices. These modifications also yield dramatic improvements in practice when they are combined with known lattice basis reduction algorithms.
Other than in Belgium, German banks may hold even controlling equity participations in industrial firms (and such firms may own banks) and do so to a large extent. Vis-a-vis the European development this leads to two questions: From the perspective of the (Belgian and other) competitors of these banks, whether their own domestic System might be disadvantageous to them. And from a public interest perspective, which advantages and drawbacks are connected with the different regulations in Europe. The article first informs about the legal framework and some statistical facts. Then the various and different reasons why banks acquire and hold shares on own account are analyzed. The following Parts deal with the various public policy arguments whether equity links between banks and industrial firms should be prohibited or not (safety and soundness of banking; autonomie de Ia fonction bancaire ; abuse of confidential information and conflicts of interest; antitrust considerations; negative and positive impacts on the respective firm). In its last part the article deals with recent proposals in the German political debate to limit stockholdings of banks. The article argues that a step-by-step approach to the Single Problems and issues (conflict of interests; anticompetitive effects etc.) should be preferred to a general limitation of stock ownership of banks.
The corporate governance Systems in the U.K. and in Germany differ markedly. German large firms have a two-board structure, they are subject to employee codetermination, their managements are not confronted with public hostile takeover bids, and banks play a major role in corporate governance, through equity stakes, through proxies given to them by small investors, and through bankers positions on the supervisory boards of these firms. One of the main issues of corporate governance in large firms, the Problem of shareholders passivity in monitoring management in Berle-Means type corporations, is thus addressed by an institutional Provision, the role of the banks, rather than by a market-oriented Solution as we find it in the U.K. with its market for corporate control through the threat of hostile takeovers. These two different approaches to corporate governance have been compared several times recently, and it was argued that a bank-based or institutional Solution has clear advantages and should be preferred. Cosh, Hughes and Singh, for example, argue at the conclusion of their discussion of takeovers and short-termism in the U.K. that the institutional shareholder [in the UK] should take a much more active and vigorous part in the internal governance of corporations. . . . In Order for such a proposal to be effective both in disciplining inefficient managements and promoting long-term investments, far reaching changes in the internal workings and behaviour of the financial institutions would be required. The financial institutions would need to pool their resources together, set up specialised departments for promoting investment and innovations - in other words behave like German banks. The following remarks seek to continue this discussion from the German perspective. The article will first attempt to evaluate the monitoring potential of our domestic bank or institution-oriented corporate governance System and then, in a further patt, compare it with that of a market-oriented Solution. lt will be argued that both Systems focus on different Problems and have specific advantages and drawbacks, and that there are still quite a few puzzles to be solved until all pros and cons of each of these monitoring devices tan be assessed. The perception that both Systems focus on different Problems suggests combining institutional monitoring with a market for corporate control rather than considering them to be contrasting and incompatible approaches. The article is organized as follows. Section II will describe the legal structure of the large corporation in Germany in more detail. Section Ill explains why a market for corporate control by the threat of public hostile takeover bids does not exist in Germany. Section IV then Shows how corporate governance in publicly held corporations with small investors is organized instead, and deals with the role of banks in corporate governance in these firms. Section V of the atticle then will try to compare the monitoring potential of a marketoriented and our bank or institution-oriented corporate governance System. Concluding remarks follow.
