This stock and flow diagram is a working draft of a conceptual model of a dune-lake system in the Northland region of New Zealand.

This model describes phosphorus cycling in a dune-lake system in the Northland region of New Zealand. It is based on stock and flow diagrams where each orange oval represents an input, while each blue box represents a stock. Each arrow represents a flow. Flows involve a loss from the stock at which they start and add to the stock at which they end.

This model describes nitrogen cycling in a dune-lake system in the Northland region of New Zealand. It is based on stock and flow diagrams where each orange oval represents an input, while each blue box represents a stock. Each arrow represents a flow. Flows reduce the stock at which they start and add to the stock at which they end.

In Leadership & Management: A Structural Perspective I offered some thoughts regarding what happens when typical management and leadership approaches are applied to a hierarchical organization structure. Having continued to consider the nature of these two activities I would now like to offer what I consider to be a systemic perspective. A perspective which differentiates the two based on the structures they foster rather than the particular activities they promote.​

This story presents a conceptual model of nitrogen cycling in a dune-lake system in the Northland region of New Zealand. It is based on the concept of a stock and flow diagram. Each orange ellipse represents an input, while each blue box represents a stock. Each arrow represents a flow. A flow involves a loss from the stock at which it starts and an addition to the stock at which it ends.

Learning is one section of the of the holistic 4 L (Learning, Loving, Living and Life-work) Dimension. With the learning the cognitive-spiritual dimension is meant, by increase of the level, from beginner to legend. From ability over implementation to economic relevance is a need of consistent further developement for each individual person.From values there originates a vision and from a vision aims.SIMULATION is not finished

This story contains a conceptual model of phosphorus cycling in a dune-lake system in the Northland region of New Zealand. It is based on the concept of a stock and flow diagram. Each orange ellipse represents an input, while each blue box represents a stock. Each arrow represents a flow. A flow involves a loss from the stock at which it starts and an addition to the stock at which it ends.
