The factor EOC fail to effectively consider in their planning: COMMUNICATION NEEDS.

The EOC is the centralized location of emergency response and recovery support operations during incidents. While tactical on-scene operations are conducted from the ICP, the EOC supports and helps coordinate ICP operations and any other adjacent incident operations.

The EOC utilizes ICS as the command-and-control structure. Within this structure, the EOC is organized into four sections to manage operations. These EOC sections include:

1. Management: Under the guidance of the EOC coordinator, this section has overall responsibility for the management and direction of all EOC activities including development, implementation and review of strategic decisions. Management directly coordinates with the EPG and ensures its strategic direction is implemented in EOC operations.

2. Operations: This section represents on-scene emergency responders and provides coordination between the EOC and field operations, including the ICP.

3. Planning and Intelligence: This section is responsible for receiving, evaluating and analyzing all disaster information and providing updated status reports to EOC management and field operations. The planning and intelligence section is also responsible for damage assessment and developing specialized technical assessments of events.

4. Logistics: Logistics is responsible for procuring supplies, personnel and material support necessary to conduct emergency responses (e.g. personnel call-out, equipment acquisition, lodging, transportation, food, etc.)

How did the British benefit from their mercantilist relationship with the American colonies? They prohibited colonists from fish

tangare [24]

Answer:

They bought raw materials from the colonies and sold them finished products.

Explanation:

As you may already know, the American territory is richer biologically than Europe. In this case, European nations with American colonies achieved a lot of profits from mercantilism, because they had strong access to the natural resources of their colonies, which served as raw material for the production of finished products. In the case of British mercantilism, the British took raw materials from America and produced finished products that they sold to other colonies, including the American ones. An example of this is cotton, which was extensively explored in the south of the country and sent to England to produce fabrics.

Why did the Intolerable Acts have a greater impact on the colonies than earlier tax acts?

Alinara [238K]

The Intolerable Acts not only attacked the economic rights of people in the Massachusetts colony, but also removed their system of self-rule and representative government. The Intolerable Acts closed the port of Boston to imports and exports, appointed a military governor, barred town meetings, and prevented the election of local officials and the selection of jurors. Although colonists viewed earlier tax acts and acts to control trade as unconstitutional, this act actually deprived them of their civil rights. The Magna Carta and British Bill of Rights of 1689 indicate that the King is not above the law, and that certain civil rights are granted to British subjects to ensure that the King does not become to powerful. Among these rights are the right to trial by a jury of one's peers, and the power of taxation resting in the hands of an elected body. Both of these rights were removed with the tax act. The colonists had no form of economic or political defense against the King's absolute rule in Massachusetts.
