Achtsamkeitstraining für die Firma? Gerne, aber bitte nachhaltig
Die weltweite Nachfrage nach Achtsamkeitstrainingskursen in Unternehmen hat in den letzten Jahren enorm zugenommen. Das große Interesse an Achtsamkeit liegt an der Hoffnung vieler Unternehmen weltweit, damit Stress im Firmenalltag abzubaün, mehr Gleichgewicht einzuleiten sowie in der Folge sogar Produktivitätssteigerungen realisieren zu können, aber auf sanfte, nachhaltige Art. Dennoch ist die Nachhaltigkeit von Achtsamkeitskursen in Unternehmen längst nicht so eingehend erforscht wie es die Popularität dieses Themas nahe legt. Das liegt hauptsächlich daran, dass bei vielen Kursen in Firmen Achtsamkeit mit Meditation gleichgestellt wird. Meditieren ist jedoch nur eine von vielen Methoden, um Achtsamkeit zu lernen und im Arbeitsalltag anzuwenden, und die Meditation ist nicht immer der beste Weg in die Achtsamkeit. In diesem Kapitel wird Schritt für Schritt erklärt, was Achtsamkeit ist und wie sie funktioniert, warum sie nicht dasselbe ist wie Achtsamkeitsmeditation und wie man Unternemen helfen kann, Achtsamkeit nachhaltig in ihre Firmenkultur einzubetten und somit langfristig zu erreichen, was sie sich durch Achtsamkeitskurse erhoffen

Non-destructive determination of floral staging in cereals using X-ray micro computed tomography (µCT)
Background
Accurate floral staging is required to aid research into pollen and flower development, in particular male development. Pollen development is highly sensitive to stress and is critical for crop yields. Research into male development under environmental change is important to help target increased yields. This is hindered in monocots as the flower develops internally in the pseudostem. Floral staging studies therefore typically rely on destructive analysis, such as removal from the plant, fixation, staining and sectioning. This time-consuming analysis therefore prevents follow up studies and analysis past the point of the floral staging.
Results
This study focuses on using X-ray µCT scanning to allow quick and detailed non-destructive internal 3D phenotypic information to allow accurate staging of Arabidopsis thaliana L. and Barley (Hordeum vulgare L.) flowers. X-ray µCT has previously relied on fixation methods for above ground tissue, therefore two contrast agents (Lugol’s iodine and Bismuth) were observed in Arabidopsis and Barley in planta to circumvent this step. 3D models and 2D slices were generated from the X-ray µCT images providing insightful information normally only available through destructive time-consuming processes such as sectioning and microscopy. Barley growth and development was also monitored over three weeks by X-ray µCT to observe flower development in situ. By measuring spike size in the developing tillers accurate non-destructive staging at the flower and anther stages could be performed; this staging was confirmed using traditional destructive microscopic analysis.
Conclusion
The use of X-ray micro computed tomography (µCT) scanning of living plant tissue offers immense benefits for plant phenotyping, for successive developmental measurements and for accurate developmental timing for scientific measurements. Nevertheless, X-ray µCT remains underused in plant sciences, especially in above-ground organs, despite its unique potential in delivering detailed non-destructive internal 3D phenotypic information. This work represents a novel application of X-ray µCT that could enhance research undertaken in monocot species to enable effective non-destructive staging and developmental analysis for molecular genetic studies and to determine effects of stresses at particular growth stages
