Validation of a large Italian Database of 15 STR loci

Results from a collaborative exercise with proficiency testing conducted by 20 Italian laboratories on the 15 loci included in the Identifiler kit were analyzed by allele sharing methods and by standard population genetics tests. The validated database, including about 1500 subjects, was merged with that of a previous exercise conducted on nine loci, and the resulting allele frequencies, subdivided by Italian region, were published on-line.     

Population data for 12 Y-chromosome STRs in a sample from Brescia (northern Italy)

Twelve Y-chromosome STRs--DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439--were typed in a population sample (n=104) of unrelated males from Brescia (northern Italy). A total of 91 haplotypes were identified by the 12 Y-STR loci. The haplotype diversity (98.68%), discrimination capacity (87.50%) and gene diversity were calculated.     

Contractual Conditions,Organizational Level,Dimension of Organization,and Work Conflict as Potential Predictors of Job Stress in Public Administration

Job stress is a pervasive problem for employers in the 21st century economy, making it a timely and important topic in organizational settings. The variables influencing job stress are numerous and consequently it may be analyzed from different perspectives, but the root is primarily physical and psychosocial. This study specifically explores three physical sources of job stress—contractual condition of work, organizational position, and dimension of organization—and of one psychosocial source—work conflict. A survey instrument was used to collect information from regional Public Administration employees of South Italy. Data from 1,130 respondents were analyzed. Statistical correlations and hierarchical regression showed that contractual condition of work, organizational position, organizational dimension, and work conflict were all predictive aspects of job stress.
