Gender differences in phonetic processing

In research on dyslexia, inadequate or inappropriate comparisons have often been made with control subjects, frequently overlooking important gender differences. More information is needed regarding the performance of control subjects, and adults, on measures purportedly assessing phonological and orthographic processing. Using tests similar to those used in dyslexic research, 20 female and 20 male college-age students were tested to examine gender differences in phonetic processing skills. The findings suggest that in equally competent readers, gender and other factors do play a significant role in determining the time it takes for phoneme manipulation and word identification. Females, especially those with poorer academic records, are significantly slower than males on measures typically used in dyslexic research. These findings show a need for a reexamination of control group equivalence (especially regarding gender), and further exploration of variables that might influence performance on these tasks.     

Organization and work of missionaries in the Middle‐Volga in the second half of the nineteenth century

The missionary effort of the Orthodox Church in the Middle‐Volga—a region conquered by Russia in the sixteenth century and inhabited by an ethnically heterogeneous population practising Islam or a variety of indigenous religions—had led to the formation of important communities of converts. But until the nineteenth century, the church made essentially no effort to educate the converts in the meaning and content of the Orthodox faith and movements of apostasy were frequent. In the mid‐nineteenth century, an outstanding group of missionaries, concerned about the spread of Islam among the nominally Christian communities, began to deploy an important activity to enlighten converts in the Orthodox faith. Their methods—evangelization, education, and propaganda in native languages—were novel and radical. Concerned with the defence of nominally Christian populations against Muslim influences, anti‐Muslim activity was an important aspect of work of the missionaries. Missionaries developed a substantial anti‐Islamic literature and used their considerable influence to harm the Muslims culturally and politically. The legacy of the missionary experience contributed to the continuing distrust between Russians and indigenous peoples.     

Computer-Based Performance Monitoring and Productivity in a Multiple Task Environment

Computer-based performance monitoring (CPM) provides managers with the ability to continuously, and unobtrusively, monitor the work performed by their employees. This paper examines the impact that CPM has on productivity when people are monitored on only a portion of the work that they perform. In a simulated work setting, subjects worked on two computerized tasks, and were led to believe that their work on one, both, or none of the tasks would be electronically monitored. People who were monitored only on a relatively simple task tended to work at a faster rate on both their monitored and non-monitored tasks, in comparison to people who were not monitored at all. People who were monitored only on a task that was more moderate in level of difficulty did not work any faster or more accurately than people who were not monitored. The results of the current study suggests that under certain conditions, employees may not discriminate between monitored and non-monitored work. Recommendations are offered to managers who are considering implementing CPM in their workplace.     

The effects of neonatal gonadectomy and prenatal stress on cortical thickness and asymmetry in rats

In Study I measures of cortical thickness were taken in 90-day-old male and female Sprague-Dawley, Wistar, and Long-Evans rats that were born to pregnant females shipped to the laboratory in late pregnancy and that were either gonadectomized at birth or left intact. No evidence for hemispheric differences in cortical thickness was found in any of the groups. Gonadectomy resulted in increased cortical thickness in male Sprague-Dawley and Wistar rats and in small increases in thickness of the left hemisphere in Long-Evans rats, especially males. No effects of gonadectomy were found in females of any strain. The lack of the expected right-over-left difference in cortical thickness in intact males may have been due to prenatal stress caused by housing, handling, and shipping. In Study 2 measures of cortical thickness were taken in 90-day-old male and female Sprague-Dawley rats that were bred in our laboratory, but otherwise similarly treated at birth. In this second study, the expected right-over-left hemispheric difference in cortical thickness was found in intact male rats; none was found in gonadectomized males or in either of the female groups. The lack of asymmetry in gonadectomized males appeared to be due to an increase in thickness in the left hemisphere. Taken together these studies provide support for the idea that hormones of testicular origin suppress cortical enlargement in the perinatal period, particularly in the left hemisphere.
