A networkwide backup system with inter‐memory autonomic copy mechanism
Authors: Mukai Ryo , Yamada Shigeki , Tanaka Satoshi , Tanaka Akira , Kubota Minoru , Kogiku Ichizo 
Published: May 2003

AbstractWe propose a networkwide backup system for a system composed of multiple primary nodes connected by a wide‐area network. The system enables us to implement the backup node physically far from the primary nodes. In this system, we can implement a replica of the primary node with low overhead, and the replica can start up when the primary node stops. The replica is made by serially transferring memory update information of a primary node to a backup node, by using a hardware‐based memory copying mechanism.In addition, our system is transparent for application programs, that is, the applications are not aware of the switchover. Thus, we need no modification to the application software, and we can build a highly reliable system using existing software.In the evaluation of a prototype system, the overhead for checkpoint processing was about 1.6 ms, and the processing time for switching to the backup node from the time fault detection was about 165 µs. This result means that our system is superior to the ordinary active replication system in terms of the overhead when the distance between a primary node and a backup node is larger than 160 km. © 2003 Wiley Periodicals, Inc.

Published: May 2003

AbstractWith the progress of computer applications to education, such facilities as databases and hypermedia have come into educational use in recent years. The mediabase system “ShareMedia” which is being developed in this study is a system that supports the description, sharing, retrieval, and examination of knowledge by students. In ShareMedia, a semantic frame is used by a community of students by common agreement. A rough semantic index is added to the media representation, so that the same community or the inheriting community can extract closely related media representations through such an index or its converted form and can use it for comparison and examination. It is intended in this study to support the inductive acquisition of generalized knowledge which applies to the domain under consideration, that is, Japanese geography and world geography as subjects in junior high school. A system was experimentally constructed and a preliminary experiment performed. The results suggested that the support of knowledge acquisition by ShareMedia browsing is useful in aiding the student to discover general knowledge and the rules in a domain with which the student is not familiar. © 2003 Wiley Periodicals, Inc.

Ownership, organization, and private firms' efficient use of resources
Authors: Durand Rodolphe , Vargas Vicente 
Published: May 2003

AbstractThe principal–agent theory asserts that public firms' performance is driven by efficient capital and labor markets but is silent about non‐listed private companies, which are less permeable to market forces (both capital and labor) than are public companies. We propose and test a 2 × 2 framework distinguishing owner‐controlled vs. agent‐led firms from firms with a flat vs. multilayer organization. Our findings provide highly contrasted results and raise important issues for further study of private firms. Copyright © 2003 John Wiley & Sons, Ltd.
Pricing process as a capability: a resource‐based perspective
Authors: Dutta Shantanu , Zbaracki Mark J. , Bergen Mark 
Published: May 2003

AbstractStrategists following the resource‐based view argue that firms can generate rents through value creation. To create value, firms develop and use resources and capabilities that other firms cannot imitate, trade for, or substitute other assets for. Even a firm that has created value, however, may not capture the potential rents associated with that value. To capture rents, a firm must set the right prices for what it sells. Most views of pricing assume that a firm can readily set appropriate prices. In contrast, we argue that pricing is a capability. To develop the ability to set the right prices, a firm must invest in resources and routines. We base our argument on a study of the pricing process of a large Midwestern manufacturing firm. We show that pricing resources, routines, and skills may help or inhibit a firm in setting the right price—and hence in appropriating value created. Our view of pricing as a capability contributes to the resource‐based view because it suggests that strategists should consider the portfolio of value creation and value appropriation capabilities a firm uses to create competitive advantage. Our view also contributes to economics because it suggests that strategic decisions about pricing capabilities have important implications for a fundamental economic action, determining prices. Managers in firms without effective pricing processes may be unable to set prices that reflect the wishes of its customers, so the customers may misuse their resources. As a result, resources may be used ineffectively. Our view of pricing as a capability therefore takes the resource‐based‐view straight to the heart of what is perhaps the central economic question: the best use of resources.

Dynamic capabilities, social capital, and rent appropriation: ties that split pies
Authors: Blyler Maureen , Coff Russell W. 
Published: May 2003

AbstractWho reaps the fruits of a dynamic capability? We argue that while social capital is essential for the acquisition, integration, and release of resources at the core of a dynamic capability, actors can also use social capital for personal gain. Thus, social capital may be a key to understanding both rent generation and rent appropriation. Even when causal ambiguity obscures individual contributions, they may use their social capital to establish credible claims on the rent. Specifically, employees who occupy structural holes, span organizational boundaries, or who are highly central may be most able to appropriate rent because their social capital grants credibility to their claims. Rent that is appropriated in this way may be unobservable in performance measures that fail to distinguish normal compensation from rent. We contribute by identifying the specific role of social capital in a dynamic capability and linking social capital to rent appropriation patterns. Copyright © 2003 John Wiley & Sons, Ltd.

Authors: Dörsam Guido , Kahlenberg Volker , Fischer Reinhard X. 
Published: May 2003

AbstractHydrothermally synthesized CsHSi2O5 was studied by single‐crystal X‐ray diffraction. The compound is orthorhombic (space group Pnma). Unit cell parameters are a = 4.9758(3), b = 8.8089(6), c = 12.9295(9) Å with four formula units per cell. The structure was solved by direct methods and refined to a residual R1 = 0.025 for 621 independent observed reflections with I > 2σ(I) and 41 parameters. Residual electron densities were used to locate positions of the H atoms. They are part of silanol groups and show a disorder involving two positions related by a center of symmetry. The resulting O—H···O distance of 2.44 Å is one of the shortest hydrogen bonded O···O distances in inorganic compounds containing silanol groups. The structure belongs to the class of unbranched zweier double chain silicates. The [Si2O4(OH)—] chains run parallel [100]. Cesium cations providing additional linkage between the anionic ribbons reside in voids between the chains and coordinate to nine oxygen ligands.

Published: May 2003

AbstractDie Kristallpackung des dreidimensionalen Koordinationspolymers Na2Cs2[(MeSO2)2N]4·3H2O (orthorhombisch, Raumgruppe Pna21, Z′ = 1) zeigt teilweise Übereinstimmung mit der des zuvor beschriebenen Natrium‐Kalium‐Doppelsalzes Na2K2[(MeSO2)2N]4·4H2O (tetragonal, P43212, Z′ = 1/2). In der vorliegenden Struktur finden sich vier mehrzähnig koordinierende unabhängige Anionen, drei unabhängige Aquoliganden und zwei Arten von Caesiumionen in Monoschicht‐Substrukturen angehäuft, die paarweise über ein [Cs(1)—H2O—Cs(2)]‐Motiv zu Doppelschichten assoziiert sind. Auf diese Weise gelangt jedes Cs+ zu einer unregelmäßigen (O8N2)‐Koordination durch Bindungswechselwirkungen mit zwei N, O‐chelatisierenden und zwei O, O‐chelatisierenden Anionen sowie zwei Wassermolekülen. Die Hälfte der Natriumionen besetzt Pseudoinversionszentren zwischen den Doppelschichten und befindet sich in oktaedrischer (O6)‐Umgebung zwischen vier Anionen und zwei Wassermolekülen, während die übrigen Natriumionen im Inneren der Doppelschichten intercaliert sind und durch Bindungen zu vier Anionen und zum Wassermolekül des [Cs—H2O—Cs]‐Motivs eine quadratisch‐pyramidale (O5)‐Koordinationssphäre mit Pseudo‐C2‐Symmetrie erreichen. Im Endeffekt verklammert jedes Anion zwei Cs+‐ und zwei Na+‐Ionen, zwei Wassermoleküle bilden [Cs—H2O—Na]‐Motive, das dritte wirkt als μ3‐Brückenligand zwischen zwei Cs+‐Ionen und einem Na+‐Ion. Die Kristallkohäsion wird unterstützt durch ein dreidimensionales Netzwerk von konventionellen (O—H···O=S)‐ und schwachen (C—H···O=S/N)‐Wasserstoffbrücken.
Crystal Structures and Thermal Behaviour of Lanthanide(III) Hexanoate 1, 10‐Phenanthroline Complexes, [M(C5H11CO2)3(phen)] and [Tm(C5H11CO2)2(NO3)(phen)]

AbstractLanthanide(III) hexanoate 1, 10‐phenanthroline complexes crystallise in the space group P21/n. The compounds consist of dimers, whereby two lanthanide ions are held together by two bidentate bridging and two tridentate bridging carboxylate groups. The first coordination sphere of the lanthanide ions is completed by one bidentate chelating carboxylate group and by one bidentate 1, 10‐phenanthroline molecule, resulting in the coordination number 9. The dimers have a spherical form, which has important consequences for the thermal properties of complexes. The basic idea behind the preparation of this type of compounds is the stabilisation of the ionic lanthanide layer, so that the smaller lanthanide ions (from which the normal alkanoates do not show mesomorphism because they are too small) show liquid crystallinity. The stabilisation of the ionic layer was successful, expressed by the high melting temperatures, but mesomorphism is not observed. The absence of mesomorphism is related to the isotropic structure of the compounds. A lower symmetry is obtained when a hexanoate group is replaced by a nitrate group. Thulium(III) dihexanoate nitrate 1, 10‐phenanthroline crystallises in the space group P1¯. However, this compound also shows a spherical dimeric structure, but no mesomorphism.
A New Oxynitride Compound of Molybdenum, Na3MoO3N — Synthesis via the Azide Route and Structure
Authors: Arumugam Nachiappan , Hönnerscheid Andreas , Jansen Martin 
Published: May 2003

AbstractThe new oxynitride compound of molybdenum, Na3MoO3N was prepared via the azide route. Its crystal structure was solved and refined from X‐ray powder data (orthorhombic, Pmn21, a = 724.63(1), b = 624.98(1), c = 563.86(1) pm, Rp: 9.04 %; Rwp: 9.83 %). The structure consists of isolated [MoO3N]3— tetra‐hedra which are separated by Na+ cations, also in a tetrahedral coordination. It is isostructural to Na3WO3N which is a lower symmetry derivative of the Cu3AsS4 structure. Due to the small difference in the scattering lengths of nitrogen and oxygen, we were unable to distinguish between fully ordered, fully disordered, or partially ordered anions. However, from the positive SHG responses, we can deduce the acentric space group being the correct one and based on the lattice energy calculations, we have been able to identify the position most probably being occupied by nitrogen.

Published: May 2003

AbstractThe title compound has been prepared from [Ti(η5‐C5Me5)Cl3] and cis‐cis‐(t‐BuSi(OH)—CH2)3 in hexane solution in the presence of Et3N. The pale yellow complex was characterized by NMR and MS spectra, as well as by a crystal structure determination. The two crystallographic independent molecules in the triclinic unit cell (space group P1¯, No. 2, Z = 4) both have a nearly identical adamantane‐like TiO3Si3C3 cage of approximate C3v symmetry. The exocyclic C—C—C bond angles in the Cp‐ligand range from 123° to 129°. A quantum chemical calculation of the free molecule predicts this range to be 124° to 127°. The arrangement of the molecules in the crystal is characteristic for an offset face‐to‐face ππ stacking of the aromatic η5‐C5Me5 rings.

AbstractDie nicht‐isotypen Nitridselenide M4N2Se3 des Neodyms (Nd4N2Se3) und Terbiums (Tb4N2Se3) bilden sich durch Umsetzung des betreffenden Selten‐Erd‐Metalls mit Natriumazid (NaN3), Selen und dem entsprechenden Selten‐Erd‐Tribromid (MBr3) nach sieben Tagen bei 900 °C in evakuierten Kieselglasampullen. Sie kristallisieren jeweils monoklin in der Raumgruppe C2/c mit Z = 4 für Nd4N2Se3 (a = 1300, 47(4), b = 1009, 90(3), c = 643, 33(2) pm, β = 90, 039(2)°) bzw. in der Raumgruppe C2/m mit Z = 2 für Tb4N2Se3 (a = 1333, 56(5), b = 394, 30(2), c = 1034, 37(4) pm, β = 130, 377(2)°). Die Kristallstrukturen unterscheiden sich grundlegend in der Verknüpfung der strukturdominierenden N3‐‐zentrierten (M3+)4‐Tetraeder. In Nd4N2Se3 sind die [NNd4]‐Einheiten zu Tetraederdoppeln kantenverknüpft, die über ihre verbleibenden vier Ecken zu Schichten [N(Nd1)(Nd2)]3+ zusammentreten, wohingegen die [NTb4]‐Tetraeder in Tb4N2Se3 durch cis‐Kantenverknüpfung zu Strängen [N(Tb1)(Tb2)]3+ kondensiert vorliegen. Beide Kristallstrukturen enthalten jeweils zwei kristallographisch unterschiedliche M3+‐Kationen, die Koordinationszahlen von sechs und sieben (Nd4N2Se3) bzw. von zweimal sechs (Tb4N2Se3) gegenüber den Anionen (N3‐ und Se2‐) aufweisen. Jeweils zwei unabhängige Sorten von Se2‐‐Anionen sorgen schließlich für die dreidimensionale Vernetzung und den Ladungsausgleich. Wegen des besonderen Achsverhältnisses a/c und des überstumpfen monoklinen Winkels ergeben sich für die Festlegung der Elementarzelle von Tb4N2Se3 zwei Auswahlmöglichkeiten.

AbstractThe synthesis and characterization of the first two Re complexes with semicarbazone ligands is presented. Selected ligands are 5‐Nitro‐2‐furaldehyde semicarbazone (Nitrofurazone) (L1) and its derivative 3‐(5‐Nitrofuryl)acroleine semicarbazone (L2). Complexes of general formula [ReVOCl2(PPh3)L], where L = L1 and L2, were prepared in good yields and high purity by reaction of [ReVOCl3(PPh3)2] with L in ethanol or methanol solutions. The complexes formula and molecular structures were supported by elemental analyses and electronic, FTIR, 1H, 13C and 31P NMR spectroscopies. In addition, the crystal and molecular structure of [ReVOCl2(PPh3)L2] was determined by X‐ray diffraction methods. [ReOCl2(PPh3)(3‐(5‐Nitrofuryl)acroleine semicarbazone)] crystallizes in the space group P‐1 with a = 11.2334(2), b = 11.3040(2), c = 12.5040(2) Å, α = 81.861(1), β = 63.555(1), γ = 83.626(1)°, and Z = 2. The Re(V) ion is in a distorted octahedral environment, equatorially coordinated to a deprotonated semicarbazone molecule acting as a bidentate ligand through its carbonylic oxygen and azomethynic nitrogen atoms, to an oxo ligand and a chlorine atom. The six‐fold coordination is completed by another chlorine atom and a triphenylphosphine ligand at the axial positions.

AbstractThe preparation of two η6‐estra‐1, 3, 5(10), 6‐tetraene tricarbonylchromium complexes 4 and 6 are described. In both cases only one stereoisomer can be isolated, in contrast to other estrane‐tricarbonylchromium complexes, where complexations are non‐stereoselective. X‐ray crystal structural analysis of 4 discloses that only the more sterically hindered β‐facial isomer is formed. It is assumed that the 6, 7‐olefinic moiety exerts a directive influence on the complexation.

AbstractTwo new transition metal(II) complexes [M(hdpa)2(N(CN)2)2] (M = Mn (1), Co (2); hdpa = 2, 2'‐dipyridylamine) have been prepared and characterized structurally and magnetically. Both compounds crystallize in the monoclinic space group C2/c. 1 and 2 are isotypic with the unit cell parameters a = 8.634(9), b = 13.541(14), c = 21.99(2) Å, β = 94.806(18)°, and V = 2562(5) Å3 for 1, a = 8.617(3) Å, b = 13.629(5)Å, c = 21.598(8)Å, β = 94.593(6)°, and V = 2528.4(15)Å3 for 2, and Z = 4 for both. According to X‐ray crystallographic studies, each metal(II) ion was six‐coordinated with four nitrogen atoms from two bidentate hdpa ligand and two nitrogen atoms from two N(CN)— anions to form slightly distorted octahedrons. Adjacent complex molecules are connected by hydrogen bonds or π···π interactions to form three‐dimensional network. The IR and UV spectroscopy were measured and the magnetic behaviors were investigated.

AbstractDurch Oxidation von Tellur mit AsF5 in flüssigem SO2 entsteht Te42+[AsF6—]2, das als SO2‐Solvat in Form dunkelroter Kristalle aus der Lösung gewonnen werden kann. Die Kristalle sind sehr empfindlich gegen Luft und gegen Verlust von SO2, weshalb sie nur unter SO2‐Atmosphäre oder unter Kühlung gehandhabt werden können. Die Kristallstruktur wurde bei Raumtemperatur, bei 153 K und bei 98 K bestimmt. Oberhalb von 127 K liegt Te4[AsF6]2 · SO2 in einer orthorhombischen Struktur vor (Pnma, a = 899, 2 (1), b = 978, 79 (6), c = 1871, 61 (1) pm, V = 1647, 13 (2) · 106 pm3 bei 297 K, Z = 4). Die Struktur ist aus quadratisch‐planaren Te42+‐Ionen (Te‐Te 266 pm), oktaedrischen [AsF6]—‐Ionen und SO2‐Molekülen aufgebaut, die über die Sauerstoffatome an die Te4‐Ringe in kantenüberbrückender Position koordinieren. Eines der beiden kristallographisch unabhängigen [AsF6]—‐Ionen zeigt bei Raumtemperatur eine Rotationsfehlordnung, die sich auch bei Abkühlung auf 153 K nicht vollständig ausordnet. Bei 127 K durchläuft Te4[AsF6]2 · SO2 eine Phasenumwandlung in eine monokline Struktur (P1121/a, a = 866, 17(8), b = 983, 93(5), c = 1860, 10(6) pm, γ = 96, 36(2)°, V = 1554, 2(2) · 106 pm3 bei 98 K, Z = 4). In der Tieftemperaturphase liegen alle [AsF6]—‐Ionen geordnet vor. Obwohl eine direkte Obergruppe‐Untergruppe‐Beziehung zwischen den Raumgruppen vorliegt, verläuft der Phasenübergang nach der ersten Ordnung mit sprunghaften λnderungen der Gitterparameter. Der Phasenübergang ist von einer Zwillingsbildung begleitet. Der wesentliche Unterschied in der Struktur der Tieftemperaturphase im Vergleich zur Raumtemperatur liegt in einer veränderten Koordination des Te42+‐Ions durch O‐ und F‐Atome benachbarter SO2‐ und [AsF6]—‐Moleküle.
