With a step-by-step guide, hands-on templates, as well as tips and tricks for facilitators, Value Network Mapping can be adopted as a sense-making and co-creating instrument for your challenge. This publication covers what Value Network Mapping is and why you should use it. By making explicit the current roles and relations within a system, it is possible to scrutinise both the system’s components and its organisation, and so help people reorganise themselves sustainably. Value Network Maps are particularly useful in settings where conventional structures can no longer be relied on. These maps take into account social, environmental and economic conditions for implementing and scaling up such changes, allowing global sustainable development goals to evolve from a shared vision to a common practice. With the use of Value Network Mapping it is possible to co-create such changes, while balancing individual needs with wider ambitions. Value Network Mapping helps in getting a grip on the structure of these sub-systems and enabling us to identify together intervention points that make sustainability transitions happen. Some practices need to change into completely new roles and relations, and others may even disappear. Sustainability transitions require changes in the structures of the sociotechnical systems that define our world. Such systemic change can be explored through the lenses of ‘sustainability transitions’: deep transformations of the structure and the dynamics of the sub-systems of our society, such as energy, food, mobility, housing, health care and finance. Map has its implementation in various classes like HashMap.Translating global sustainable development goals into concrete actions for systemic change remains one of the greatest challenges of our times. This method provides a collection-view of the values in the map. Returns a collection containing the values in the map. It returns NULL when the map contains no such mapping for the key. Returns the number of key/value pairs in the map. The get () method of Map interface in Java is used to retrieve or fetch the value mapped by a particular key mentioned in the parameter. Puts all the entries from m into this map. Otherwise, the previous value linked to the key is returned. Returns null if the key did not already exist. The key and value are k and v, respectively. Puts an entry in the invoking map, overwriting any previous value associated with the key. This method provides a set-view of the keys in the invoking map. Returns a Set that contains the keys in the invoking map. Returns true if the invoking map is empty. #Method map code#Returns the hash code for the invoking map. Returns the value associated with the key k. It allows you to organize your notes by dividing them into branches, enabling you to establish relationships between the topics. () is a built-in array method for iterating through the elements inside an array collection in JavaScript. Returns true if obj is a Map and contains the same entries. Note-taking method 5: The Mapping Method Another visual note-taking style is the Mapping Method. The set contains objects of type Map.Entry. Returns a Set that contains the entries in the map. Returns true if the map contains v as a value. Returns true if the invoking map contains k as a key. Removes all key/value pairs from the invoking map. Several methods throw a NoSuchElementException when no items exist in the invoking map.Ī ClassCastException is thrown when an object is incompatible with the elements in a map.Ī NullPointerException is thrown if an attempt is made to use a null object and null is not allowed in the map.Īn UnsupportedOperationException is thrown when an attempt is made to change an unmodifiable map. After the value is stored, you can retrieve it by using its key. Given a key and a value, you can store the value in a Map object. A key is an object that you use to retrieve a value at a later date. The Map interface maps unique keys to values.
