In order to remain successful, business organizations need to continuously adapt and respond to a changing environment. Rapid growth poses significant challenges to managers, not least with regard to maintaining the balance between efficiency and creativity in their organizations. Using the example of a wholesale company operating in the potted plants value chain in the lower Rhine valley, Germany, the case illustrates how the company was able to exploit the opportunities arising from the concentration in the value chain, and the necessity to adjust their organizational model in response to these changes. The case chooses the example of a small- and medium-sized enterprise (SME) as such firms constitute the prevalent type of enterprises in Germany. Simultaneously, SMEs often find it particularly difficult to adapt their tangible and intangible resources to such changes. The current material is intended to help train future managers mastering this challenge.

The Old Saxon ending of the NAp of the masculine a-stems is generally -os in the larger sources Heliand and Genesis, appears as -as in minor texts, but faces competition from -a in minor texts in south-western sources. There are various hypotheses about the origin of the -a-ending, whether going back to the original Proto-Germanic accusative ending or being a borrowing from Franconian. An analysis of all 119 attested NAp forms of masculine -(j/w)a-stems from minor texts reveals that the ending -a arose in the late 9th century and found its roots indeed in the south-western region of the Lower Rhine Valley (Essen, Werden). The variant -os, next to geographically dominant -as, is only found in that region as well. The ending -a most likely spread from Lower Rhine Valley Franconian, where an intense contact existed between Franconian and Saxon, the former being the politically dominant variety. This borrowing was the first step in a total reshaping of Middle Low Saxon plural morphology, based on the Franconian pattern of masculine -e versus feminine -en.

Abstract. From the waterworks of Bensberg east of Cologne and a gravel-pit near Efferen west of Cologne, there have been described layers of clay and fine-sand, containing fossils with humus layers from a depth of about 16 to 18, 20 meters below the surface of the Lower Middle-Terrace of the Rhine (i.e.: about 58 m above sea-level). These sediments enable us to separate stratigraphically in the sand-gravel-sequences the overlying from the underlying stratum one. Heavy mineral analysis shows, that the underlying series belongs to the Middle Middle-Terrace of the Rhine (of Late-Mindel-age). The distribution of this terrace within the Lower-Rhine-Basin thus cannot be limited only to some narrow channels („Channel-Gravel"), but is supposed to be developped over the whole breadth of the valley, like in the Middle-Rhine-Valley, yet here buried under sediments of the Lower Middle-Terrace. The palynologic investigation of the humus layers within the clay and flnesand-layers of the waterworks of Bensberg shows a flora indicating a late-interglacial age by their high percentage of Abies-Alnus-Picea-values. According to the stratigraphical findings they can only be attached to the Mindel/Riß-interglacial Krefeld-Beds. The investigations carried out led to a critical examination of the existing attempts of difTeren-ciating the Middle-Pleistocene beds in the Lower-Rhine Basin. The Kempen and Neuwerk Beds have to be separated from the Krefeld Beds, according to both the stratigraphic and the floristic and faunistic findings, and must be attached to the Gerdau-Interstadial, the first one probably belonging to a late and the latter (much more probably) to a middle part of this Drenthe/Warthe-Interstadial. The authors try to give a climatic-chronologic table of all Middle Pleistocene beds in the Lower-Rhine-Basin.

A Chézy-based hydraulic model was run to estimate the magnitude of extreme floods of Middle Holocene age in the Lower Rhine Valley (Germany). Input parameters were gathered from the field and literature, and used in ten scenarios to calculate a best guess estimate for the minimum size of extreme floods. These events have been registered as slackwater deposits on elevated terrace levels and in a palaeochannel fill. The modelled minimum discharge is 13,250 m3 sec−1 for a Middle Holocene flood with an estimated recurrence interval between 1,250 and 2,500 years. A sensitivity analysis on different input parameters enables evaluation of factors which cause the relatively large range in modelled discharges. Understanding the origin of uncertainties in modelled discharges is important for making geologically based calculations of palaeoflood magnitudes important in modern flood frequency analyses, which generally lack information on the magnitudes of rare events.

Abstract. In the Middle and Lower Rhine Valley the age of loess deposits is recognized by their relation to the Lower Middle Terrace of the Mosel and Rhine Rivers. Nearly all loess is regarded to be Würm-loess, which is separated by several soil zones. In the lower part of the Würm-period climatic changes are clearly indicated by thickly and well developed soil zones („Parabraunerde"). Later on soil zones become generally thin and less distinct („Naßböden"). In this later period, at some places, one soil zone is typical („kalkhaltige Braunerde"). In the profile of Metternich this horizon included artifacts (Gravettian).

AbstractThirteen glacial terraces are known from the western part of the northern Alpine foothills between the Lech and Iller Rivers. In the Lower Rhine region of West Germany, a similar number of terraces are capped by interglacial floodloams and soils. Whereas the environment during individual interglaciations did not differ substantially, the glaciations were progressively more severe. The Main Terrace system of the Rhine may be an exception. The duration of the Quaternary, starting at the base of Praetiglian, is estimated at approximately 2 million yr by paleomagnetic dating. The major cold-warm climatic cycles of the earliest Pleistocene lasted approximately 100,000 yr, the same as those of the Brunhes Chron. The intervening Main Terrace system has not yet been climatically subdivided. Correlation with the Netherlands is possible because of an abundance of paleobotanic and paleomagnetic evidence. In the Alpine foothills, stratigraphically useful indicators of warm climates are missing, but analogies in terrace development permit comparison with the Lower Rhine and Danube. The terrace sequence in the Alpine foothills is incomplete, as are those along most of the other rivers in Europe. Some of the older terraces may have been eroded.
