ScaleLarvalHabitat

The ScaleLarvalHabitat intervention class enables species-specific habitat modification within shared habitat types. This intervention has a similar function to the demographic parameter ScaleLarvalMultiplier, but enables habitat availability to be modified at any time or at any location during the simulation, as specified in the campaign event.

Note

Parameters are case-sensitive. For Boolean parameters, set to 1 for true or 0 for false. Minimum, maximum, or default values of “NA” indicate that those values are not applicable for that parameter.

EMOD does not use true defaults; that is, if the dependency relationships indicate that a parameter is required, you must supply a value for it. However, many of the tools used to work with EMOD will use the default values provided below.

JSON does not permit comments, but you can add “dummy” parameters to add contextual information to your files.

The table below describes all possible parameters with which this class can be configured. The JSON example that follows shows one potential configuration.

Parameter	Data type	Minimum	Maximum	Default	Description	Example
Disqualifying_Properties	array of strings	NA	NA	[]	A list of NodeProperty key:value pairs that cause an intervention to be aborted (persistent interventions will stop being distributed to nodes with these values). See NodeProperties and IndividualProperties parameters for more information. Generally used to control the flow of health care access. For example, to prevent the same individual from accessing health care via two different routes at the same time.	{ "Disqualifying_Properties": [ "InterventionStatus:LostForever" ] }
Intervention_Name	string	NA	NA	NA	The optional name used to refer to this intervention as a means to differentiate it from others that use the same class.	{ "Intervention_Config": { "class": "ScaleLarvalHabitat", "Intervention_Name": "Reduce habitat for Aedes aegypti" } }
Larval_Habitat_Multiplier	JSON object	NA	NA	NA	The value by which to scale the larval habitat availability (specified in Larval_Habitat_Types in the configuration file) per intervention, across all habitat types, for specific habitat types, or for specific mosquito species within each habitat type. See Larval habitat parameters for more information.	The following example scales the larval habitat equally across all habitat types and mosquito species. { "Larval_Habitat_Multiplier": 2.0 } The following example scales the larval habitat only in the temporary rainfall habitat for all mosquito species. { "Larval_Habitat)Multiplier": { "TEMPORARY_RAINFALL": 2.0 } } The following example scales the larval habitat independently for A. gambiae in the temporary rainfall habitat and for A. arabiensis in the brackish swamp habitat. { "Larval_Habitat_Multiplier": { "TEMPORARY_RAINFALL": { "gambiae": 2.0 }, "BRACKISH_SWAMP": { "arabiensis": 2.5 } } }
New_Property_Value	string	NA	NA	NA	An optional NodeProperty key:value pair that will be assigned when the intervention is distributed. See NodeProperties and IndividualProperties parameters for more information. Generally used to indicate the broad category of health care cascade to which an intervention belongs to prevent individuals from accessing care through multiple pathways. For example, if an individual must already be taking a particular medication to be prescribed a new one.	{ "New_Property_Value": "InterventionStatus:None" }
