    This article investigates information quality within multi-actor service networks offering safety telephone services for ageing people. A clear connection between the quality of information and success of business has been acknowledged, but tools for analysing information quality in network environments on the basis of qualitative data have been lacking. There is also a limited understanding of information processes of virtual networks of public and private service organizations in the literature. In the present article, a novel framework for information quality analysis is introduced and operationalized. The framework extends previously developed methods and provides a fundamentally different way to assess information quality, contrary to earlier quantitative studies. Operationalization of the newly developed framework is undertaken in the virtual network environment of safety telephone services for ageing people. These services utilize rapidly developing well-being technology. The analysis is based on data from interviews with professionals working in several service networks of different types and sizes in Finland. The results provide a detailed account of the state of information quality in the case networks. Such results can be utilized as guidelines when planning information-related matters in the case networks in the future.

    Two old, one new and two current genus names are discussed. The old names are Schizoctopus Hoyle, 1886, for which a type species is here designated, and Tritaxeopus Owen, 1881, which is here associated with the ‘Octopus horridus group’ of species. The two current genus names concern two species of octopus with males hectocotylized on the third left arm: Scaeurgus unicirrhus (delle Chiaje in d’Orbigny, 1841) and Pteroctopus tetracirrhus (delle Chiaje, 1830). The type species of the genus names Scaeurgus and Pteroctopus have been identified as synonyms (rendering these genus names synonyms, also) but approval of an unchallenged redesignation of the type species of Scaeurgus provides an appropriate solution to this problem that would best maintain taxonomic stability.
    A new genus name is proposed for the species Octopus januarii Hoyle, 1885, which was previously placed in Benthoctopus Grimpe, 1921. This follows the recent identification of the type species of three genera (Bathypolypus, Benthoctopus and Atlantoctopus, all described by Grimpe, 1921) as belonging to a single genus (excluding Octopus januarii), of which Bathypolypus is the senior synonym. It is here observed that the species closest in morphology to Hoyle’s ‘Octopus’ januarii appears to be ‘Octopus’ longispadiceus (Sasaki, 1917), although the former has no ink sac while the latter has. The common features of these two species include close similarities in the internal structure of the male pseudophallus. Comparisons are made with structural features of the pseudophallus in Enteroctopus dofleini (Wülker, 1910), ‘Octopus’ hongkongensis Hoyle, 1885, and ‘O.’ conispadiceus (Sasaki, 1917), and it is suggested that all five species may be related at the subfamily level.

    A catalogue of the extant specimens of recent Cephalopoda in the Museum of Tokyo University is here presented including 50 lots of recently designated type material, mostly from species described by Sasaki. Also identified are the specimens of many other species described by Sasaki in his monograph of 1929. An Appendix provides an English summary of a largely ignored nineteenth century list of the oldest specimens in the ZUMT collection, published in Japanese, for comparison with the present collection.

    For crosslinked high polymers, the effect of crosslinkages to the frequency-dependent complex modulus is estimated with the aid of a network model. It is then shown that it can be used to explain the deviation of experimental values for a material of crosslinked high polymers, from the theoretical values for a dilute solution of high polymers. Some discussions are given also on the relaxation modulus.

    Inequalities between volume mean-values and spherical mean-values of functions are closely related to subharmonicity or log. subharmonicity. We shall obtain some results concerning these relations.

    Given a connected weighted graph G=(V,E), we consider a hypergraph H(G)=(V,F(G)) corresponding to the set of all shortest paths in G. For a given real assignment a on V satisfying 0≤a(v)≤1, a global rounding α with respect to H(G) is a binary assignment satisfying that |∑vFa(v)−α(v)|<1 for every FF(G). Asano et al. [3] conjectured that there are at most |V|+1 global roundings for H(G). In this paper, we present monotone properties on size and affine corank of a set of global roundings under a clique connection operation.

    In previous papers, the author defined a notion of admissible functions on digraphs, studied its properties, and gave a divergence-like characterization of admissible functions on digraphs from the view point of foliated theory. In this paper, we give a purely combinatorial proof of the characterization of admissible functions on digraphs.

    The primary goal of the present study was to develop and examine a new perceptual priming test—Kanji clarification test (KCT)—, which is designed to minimize the effects of conceptual influences on perceptual priming using single Kanji characters as test materials. In Experiment 1, manipulation of attention in the study phase did not affect perceptual priming on the KCT, whereas it significantly influenced performance in the corresponding explicit memory test. In Experiment 2, priming effects on the KCT was eliminated when different form (in Kana script) of target items had been presented at study even though performance in recognition test showed significant memory of those studied target items. Results from the two experiments indicate that the KCT is a sufficient and sensitive perceptual priming test for implicit memory research using single Kanji characters.
