A case study of growers conception of irrigation strategies indicates that pot plant growers in Scandinavia base their management approaches on experientially based art. The study also indicates that there is a gap between experientially based art and available greenhouse technology. In order to standardize production and produce quality, both the grower’s experience and available technology should be taken into account. In order to achieve this, the present study proposes to arrange reflection on reflection in action with a group of (...) growers by means of the dialogue seminar method. The concept of reflection on reflection in action is novel to horticultural practice. Therefore, we suggest future inter- and multidisciplinary research within this domain. (shrink)

There has been no major critical edition of Velleius with commentary since that of Kritz in 1840. Kritz, who took into account Sauppe's long essay on Velleius of three years earlier, was preceded by Ruhnken, whose commentary appeared in 1779. During the century which followed Kritz's work several valuable editions without commentary were produced, the last of which, by Stegmann de Pritzwald , almost coincided with the essay and bibliography devoted to Velleius in Schanz-Hosius . These two (...) contributions of the thirties remain standard to the present day. (shrink)
