    Virtual communities in cyberspace (1996)
    Bingley : Emerald
    Kybernetes 25 (1996), S. 60-66

    Notes: Reintroduces alienation theory and research. Considers alienation in a cybernetic sense as a generic term for different types of information processing problems in individuals. Considers these, more often than not, to be ultimately caused by developments in their social environment and reflecting back on that environment. Discusses the emergence of virtual communities, giving as an example the Thematic Group on Sociocybernetics and Social Systems. Describes its function and composition in a virtual community context. Considers whether Norbert Wiener foresaw the emergence of virtual communities and examines the link with the society envisaged by Niklas Luhmann.

    The challenge of sociocybernetics (1995)
    Bingley : Emerald

    Notes: Summarizes some of the important concepts and developments in cybernetics and general systems theory, especially during the last two decades. Shows how they can indeed be a challenge to sociological thinking. Cybernetics is used here as an umbrella term for a great variety of related disciplines: general systems theory, information theory, system dynamics, dynamic systems theory, including catastrophe theory, chaos theory. Also considers the emerging "science of complexity", which includes neural networks, artificial intelligence and artificial life, and discusses the methodological drawbacks of second-order cybernetics.

    Middle Cambrian fossils from Tizi N'Tichka, the High Atlas, Morocco. Part 1. Introduction and trilobites (1997)
    Paleontological Society
    Details
    Publication Date: 1997-07-01
    Description: New finds of the trilobitesCobboldites tichkaensisGeyer, 1988,Pseudocobboldia pulchra(Hupé, 1953),Protolenus(Protolenus)densigranulatusGeyer, 1990,Latoucheia(Latoucheia)tichkaensisHupé, 1953, andAcanthomicmacca neltneriHupé, 1953, from the basal Middle Cambrian near the peak of Tizi n'Tichka in the central High Atlas, Morocco, supplement the known morphology of these species; the trilobitesAcanthomicmaccanew species,Oreisator tichkaensisnew genus and species, and“Parasolenopleura”sp. from that locality are new.Acanthomicmacca neltneriis the first species of the genus and family that is described and figured in detail in terms of morphologic plasticity and ontogeny;Oreisator tichkaensisis the first ptychopariacean trilobite formally described and based on material from Africa. Trilobites and other fossils from the locality suggest a strong affinity to other Mediterranean and to Avalonian faunas, which is well supported by helcionelloid and hyolith genera.

    Neltneriidae and Holmiidae (Trilobita) from Morocco and the problem of Early Cambrian intercontinental correlation (1995)
    Paleontological Society
    Details
    Publication Date: 1995-05-01
    Description: Previously undescribed Holmiidae from the Sectigena Zone of Morocco indicate correlation of this zone with other zones bearing Holmiidae on Baltica, Avalonia, Siberia, and Laurentia. The occurrence of the youngest Antatlasiinae in the Sectigena Zone and the oldest Protoleninae in the overlying Hupeolenus Zone suggests correlations of the Sectigena Zone with upper Atdabanian beds bearing the youngest Antatlasiinae and the Hupeolenus Zone with Botomian beds bearing the oldest Protoleninae in Siberia. The occurrence, in the overlying Hupeolenus and Cephalopyge Zones, of Paradoxides s.l. in association with the olenelloid Cambropallas and with trilobites characteristic of the Lower Cambrian “Protolenus” Zone of Avalonia calls into question the major criteria for recognition of strata of Early and Middle Cambrian age. New taxa include lyouella contracta n. gen. and sp. of the Holmiidae and Bondonella sdzuyi n. sp. of the Neltneriidae. The known species of Neltneria, N. jacqueti and N. termieri, are revised.

    Protorthacean brachiopods from the Middle Cambrian of Morocco (1997)
    Paleontological Society
    Details
    Publication Date: 1997-09-01
    Description: Protorthacean brachiopods from the Middle Cambrian of the Moroccan Atlas regions are described in terms of morphology and systematic affinities. The superfamily Protorthacea is revised to include both Protorthidae and Bohemiellidae. Newly introduced is the protorthid genus Saesorthis, the morphologic characteristics as well as the significance of which are discussed in detail together with their bearing on early phylogeny of the Orthacea. A reinvestigation of Brahimorthis antiqua led to the recognition of additional morphologic peculiarities and enhances understanding of its stratigraphic occurrence. Additional descriptions and discussions deal with informally described protorthid and bohemiellid species. Bohemiella and Jamesella are reported from Africa for the first time.

    Middle Cambrian fossils from Tizi N'Tichka, the High Atlas, Morocco. Part 2. Hyolitha (1997)
    Paleontological Society
    Details
    Publication Date: 1997-07-01
    Description: Shelly fossils from the basal Middle Cambrian, near the peak of Tizi n'Tichka in the central High Atlas, Morocco, include the new hyolithids Oboedalites peregrinus new species, Emarites decorissimus new genus and species, Patholites insolitus new genus and species, Rodentilites cricetus new genus and species, Slapylites afer new species, Tajinella mosei new genus and species, and Tizilites creber new genus and species. New orthothecid hyoliths are Gracilitheca destombesi new species, Contitheca chrosniaki new species, Sysoievia exilis new genus and species and an indeterminate species of Circotheca. The presence of Obeodalites, Slapylites, and Contitheca suggests a strong affinity to other Mediterranean and to Avalonian faunas. Their occurrence in Morocco extends their geographic ranges from Europe, and further reenforces their usefulness as indicators of Middle Cambrian age.
