DNA profiling using STRs on the 310 and 3100 Genetic Analyzers routinely generates electropherograms that are analyzed with the GeneScan software available from the instrument's manufacturer, Applied Biosystems. Users have been able to choose from three different smoothing options that have been known to result in significant differences in the peak heights that are reported. Improvements in the underlying algorithm of the most recent version of the software also result in significant and somewhat predictable differences in peak height values. Laboratories that have performed validation studies using older versions of GeneScan should either reanalyze the data generated in those validation studies with the newest version of the software or otherwise take into consideration the systematically higher peak height values obtained as they begin following the recommendation of the manufacturer and use the new algorithm. 相似文献

The MMPI-2 and the Inwald Personality Inventory were employed to investigate the personality characteristics of dropouts from
a state police academy. A traditional model of training borrowed from military models was used at the academy rather than
a police generated model. Sensitive and independent individuals, more compatible with modern community policing methods may
have rejected police work as a result of the experience. 15 academy completers and 9 dropouts were used in the sample. Analyses
of the scales of the MMPI-2 and the Inwald Personality Inventory identified variables upon which the two groups differed.
The hypothesis that more sensitive, empathic and independent individuals were leaving the academy appeared to be supported. 相似文献

The Draw A Person test has continued to be one of the most frequently utilized psychological tests with children and adolescents. This is especially true for the child/adolescent populations in state hospitals. Because of the frequent criticism leveled against the DAP's validity, this study was undertaken in order to provide normative data for the DAP with this particular clinical population. Previous research has focused on the drawings of the same sex as the subjects; this study deals with the characteristics of the drawings of the opposite sex. The subjects were 84 male and 66 female psychiatric patients from the Adolescent Unit (AU) at Rusk State Hospital. As each patient was admitted to the AU, he was scheduled for psychological testing, with the DAP, the Revised Beta, and the MMPI being a part of this testing. The results of this study indicate that IQ ranking is the most significant factor affecting DAP test performance by male subjects. IQ ranking was not found to significantly influence the drawings by females. Neither MMPI test performance nor social background factors were shown to significantly affect DAP test performance. It is suggested that in order for the DAP to become a more objectively utilized personality technique, a scoring method should be developed that takes into account the overall quality of the drawing in conjunction with the individual details of each area of the figure drawn. More focus should also be given to the characteristics of the opposite-sex figure drawn by the subjects and its potential interpretation.Received his M.S. degree in psychology from North Texas State University in 1968.

Childhood obesity is in important respects a result of legal policies that influence both dietary intake and physical activity. The law must shift focus away from individual risk factors alone and seek instead to promote situational and environmental influences that create an atmosphere conducive to health. To attain this goal, advocates should embrace a population-wide model of public health, and policymakers must critically examine the fashionable rhetoric of consumer choice. 相似文献
