Confirmatory factor analysis of the Wechsler Memory Scale-Revised in a sample of clients with alcohol dependency

Previous analyses of the Wechsler Memory Scale-Revised (WMS-R; Wechsler, 1987) have reported one-, two-, and three-factor solutions and raised questions about the validity of the visual memory subtests. These various findings may stem in part from different methods of analysis, and from the study of different participant samples. To address these issues, we analysed data from the WMS-R and a spatial maze test administered to 154 participants with a history of alcohol dependence. Results from confirmatory factor analysis supported the interpretation of three factors underlying the WMS-R subtests and the spatial maze score in this sample, namely, attention-concentration, immediate memory, and delayed recall. This result held despite the inclusion of the maze score which is a well-validated measure of visuo-spatial memory.

Task analysis training of case managers to assist seriously mentally ill patients find roommates and housing

This study examined the efficacy of task analysis training for case managers helping seriously mentally ill patients find roommates and housing. Behavioral objectives and task analysis were used to develop the task-oriented behavioral training program. Case managers were trained to use a checklist for every session with patients, which included the goal of the session, tasks required to accomplish that goal and lists of all the sub-tasks. The results of this study suggest that this methodology: (1) reduced the time required for patients to find roommates and housing; (2) increased the percentage of patients finding housing; and (3) decreased hospitalization rates occurring during the process of looking for roommates and housing.

ID-based threshold decryption secure against adaptive chosen-ciphertext attack

This paper proposes an identity-based threshold decryption scheme IB-ThDec and reduces its security to the Bilinear Diffie-Hellman problem. Compared with previous work, this conceals two pairing computations in the ciphertext validity verification procedure. The formal proof of security of this scheme is provided in the random oracle model. Additionally, we show that IB-ThDec can be applied to the threshold key escrow and the mediated cryptosystems.
