Homeland Security - Response & Recovery - Essay Example , when to release it?, how to release it?, where to release it?, whom to release it to?, and why to release it?† (Leader for Leaders, 2010). The first step I will take before making any public interviews or communication is to analyze the different stakeholders involved in the specific disaster scenario. This entails the identification and relationship of various stakeholders to the current situation. The second step I will take after identifying the different stakeholders is to determine what specific goals or objectives I have to achieve so the needs of all those involved are addressed. Last but not the least is the third step where an appropriate technique for appraising results is established (Goldschmid, 2011). In a disaster situation, the stakeholders are the general public and the various agencies who are involved in the operation. Having been able to determine those concerned in the disaster scenario, my objective now as the Director of Media Relations is how to communi cate effectively with all of them bearing in mind the factors of communication failure and success. According to Leaders for Leaders (2010) there are five types of communication letdowns that often jeopardize the success of an operation in disaster situations. These communication letdowns or failures which I must avoid are: â€Å"1. ... Therefore the messages given out by the various agencies involved in the operation must be consistent with each other so that the people do not lose faith in officials making the statements. Aside from this a back-up plan must be established when and if the normal communication lines get damaged, which makes it hard for everyone to communicate with each other. A perfect example is the time when Hurricane Hugo devastated South Carolina, where all the communications of relief agencies from various levels of the government were unable to coordinate with each other making the whole relief operation inefficient (Miskel, 2006). The next kind of communication failure is the information released late, where the public is left guessing as to what is really happening and what they should do. In cases of disaster an immediate answer is necessary to prevent the people from taking steps to follow the advises of others whose only interest is to take advantage of the present situation. The third co mmunication failure is paternalistic attitudes where certain facts are withheld. It is essential that people must be given the true facts about the situation and are given the leeway to come up to their own conclusion. By telling the public what they need to know, they are in a better position to decide whether they should or should not be worried about the disaster that happened (Leaders for Leaders, 2010). The fourth communication failure is not countering rumors in real-time. To be able to respond to false information, agencies involved in the recovery operations must monitor the situation as it progresses. This involves being tuned to all information outlets like broadcasts from television and radio

Rating Your Dimensional Data Warehouse - Article Example While a sum total score of 0 would indicate a system completely unsupportive of a dimensional approach, a score of 20 would indicate a system that is fully supportive of a dimensional approach. The author outlays 12 of the 20 criteria in the article. Some of the criteria that pertain to the Architecture of the Data Warehouse are: Explicit Declaration, Conformed Dimensions and Facts, Dimensional Integrity, Open Aggregate Navigation, Dimensional Symmetry, Dimensional Scalability and Sparsity Tolerance, etc. Kimball explains Open Aggregate Navigation as follows: â€Å"The system uses physically stored aggregates as a way to enhance performance of common queries. These aggregates, like indexes, are chosen silently by the database if they are physically present. End users and application developers do not need to know what aggregates are available at any point in time, and applications are not required to explicitly code the name of an aggregate. All query processes accessing the data, even those from different application vendors, realize the full benefit of aggregate navigation.† (Kimball, 2000) Similarly, some of the criteria that fall under Administration category are: Graceful Modification, Dimensional Replication, Dimension Notification, Surrogate Key Administration, International Consistency, etc. Kimball explains Dimensinal Replication as follows: â€Å"The system supports the explicit replication of a conformed dimension outward from a dimension authority to all the client data marts, in such a way that we can only perform drill-across queries on data marts if they have consistent versions of the dimensions. Aggregates that are affected by changes to the content of a dimension are automatically taken offline in each client data mart until we can make them consistent with the revised dimension and the base fact table.† (Kimball, 2000) One of the impressive aspects of the article is its compact
