Conduct online research on a recently developed psychological therapy. It could be an innovation in any of the major therapeutic approaches (cognitive, behavioral, psychoanalytic and psychodynamic, or humanistic therapies), or it could be an independent approach in the making. Write about how to conduct the therapy and how it helps patients. Cite studies on the effectiveness of the therapy, discuss their results, and provide data to support the conclusions.

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
