Die Faunenhorizonte der "Subfurcaten-Schichten" (Bajocium, Niortense-Zone) in Nordwestdeutschland

Aufgrund neuer Aufschlüsse der "Subfurcaten-Schichten" (Bajocium, Niortense- Zone) in Nordwestdeutschland ist es möglich, die Schichtenfolge in Ammonitenfaunen-Horizonte zu untergliedern. Eine paläontologische Revision der Ammonitengattung Strenoceras HYATTmit den Untergattungen Strenoceras HYATT(m) und Garantiana HYATT(M) wird durchgeführt.Because of new exposures in the "Subfurcaten-Schichten" (Bajocian, Niortense- Zone) in Northwest Germany it is possible to subdivide the sequence in ammonite faunal horizons. A palaeontological revision of the genus Strenoceras HYATTwith the subgenus Strenoceras HYATT(m) and Garantiana HYATT(M) is executed

A new Bajocian profil (middle Jurassic) in the "Osnabrücker Bergland" (Niedersachsen)

In den Jahren 1984-1986 wurde südöstlich von Osnabrück beim Bau der Autobahn (A 33) ein großer Aufschluß im Bajocium und Bathonium geschaffen. Mit Hilfe der horizontiert aufgesammelten Ammoniten konnte das Bajocium im Osnabrücker Bergland entsprechend den Standard-Zonen und -Subzonen der nordwesteuropäischen Faunenprovinz untergliedert werden.During the construction of the motorway (A 33) southeast of Osnabrück a large exposure in the Bajocian and the Bathonian was created in the years 1984-86. By means of the ammonites which had been collected, bed by bed it was possible to subdivide the Bajocian in the "Osnabrücker Bergland" according to the habitat-zones and sub-zones of the Northwest European province of faunas

Immigration of the genus Macrocephalites Spath and the Bathonian biostratigraphy of the Kachchh basin (Western India, South Tethys)

The Bathonian occurrences of Indonesian Macrocephalites from the Kachchh basin (Western India) (and correspondingly the immigration of the genus into the basin) is evaluated in context of improved biostratigraphy and new ammonite data vis-à-vis European and Submediterranean records. The Indonesian Middle Bathonian macrocephalitids [Macrocephalites bifurcatus transient intermedius (Spath) (M), M. bifurcatus transient cf. intermedius (Spath) (M), M. bifurcatus transient aff. bifurcatus Boehm (m) and M. cf. etheridgei Spath (m)], have largely been recorded from a single dome, Jumara (from the basal Yellow bed, bed A4), with additional singular occurrences of M. cf. etheridgei Spath (m) from the adjoining Nara and Jhura domes (Kachchh). In Jumara, the Indonesian macrocephalitids are associated with Micromphalites (Clydomphalites) clydocromphalus Arkell (M), Procerites (Gracilisphinctes) arkelli Collignon (M), P. (G.) intermedius Jain (m), P. hians (Waagen) (M), Wagnericeras sp. (m), Parapatoceras distans (Baugier and Sauzé) (M), Sivajiceras congener (Waagen) (M and m), Macrocephalites triangularis Spath (M and m), Epimorphoceras decorum (Waagen) (M), and Reineckeia sp. A and B (M). This fauna is correlated with the European early Middle Bathonian Progracilis Zone. Both Jumara and the adjoining Jara domes have also yielded characteristic Indonesian Late Bathonian macrocephalitids – M. cf. keeuwensis Boehm (M and m), M. keeuwensis var. aff. forma flexuosa Boehm (m) and M. cf. mantataranus Boehm (M). In light of improved high–resolution stratigraphy, the Kachchh Bathonian fauna is evaluated and an improved biostratigraphy of the basin is proposed

Late Bajocian bioevents of ammonoid immigration and colonization in the Arequipa basin (Pumani river area, Ayacucho, southern Peru)

Strata of the Socosani Formation in the Pucayacu and Pumani sections (Ayacucho Department, Peru), along several kilometers, have yielded Upper Bajocian ammonoid fossil-assemblages characterized by the occurrence of juvenile individuals belonging to endemic or pandemic taxa, such as Megasphaeroceras and Spiroceras respectively. In addition, certain Bajocian taxa relatively common in the Mediterranean-Caucasian Subrealm, but very scarce in the Eastern Pacific Subrealm, such as the strigoceratid Cadomoceras and the phylloceratid Adabofoloceras, occur in this area. These Late Bajocian bioevents of regional appearance of immigrant ammonoids and even sustained colonization should be associated with an episode of maximum deepening, maximum relative sea-level rise and highest oceanic accessibility of a Bajocian-Bathonian deepening/shallowing palaeoenvironmental cycle in the Arequipa Basin, during the Late Bajocian Niortense Biochron

Methodological problems with evaluating change efficiency

Motivation: Changes result from a turbulent environment and internal situation of an organization. Rarely do changes happen spontaneously, usually they stem from decisions consciously shaped and taken by the management. Both the reasons as well as consequences of changes appear on multiple grounds and areas, often strongly interrelated. This leads to far-reaching consequences, mainly difficulties in practical operations as well as consequences for studies, analyses and related scientific generalizations and the conclusion-drawing process in both domains.Aim: Purpose of this article is to present and make a critical analysis of the existing achievements in the area of evaluating change efficiency, and indicate opportunities and difficulties in formulating new, in particular synthetic, indicators of change efficiency. Methodology applied in this paper is deductive and based on collected data and their critical analysis.Results: Managers need synthetic measures that are hard to develop. Various methods may be used in order to do it, starting from simple and complex point scales and ending up with methods applied in other sciences, e.g. the Geneva method or its variations applied to evaluate the standard of living and development. Still this requires the isolation of main analytical measures, their upper and lower thresholds, in subsequent change or process areas, and the application of statistical methods to calculate change status or effect. Such action requires longer change planning and preparation, readiness on the part of the managerial staff, and continuous monitoring with active participation of leaders and change managers.</p
