Differences in Depressive Symptoms as a Function of Gender, Roles, and Rumination

Description: Research indicates that women are more likely to experience depression than are men. The current study examined the effects of gender, socialized gender roles, rumination, and neuroticism on symptoms of depression in young adults. As predicted, rumination mediated the relationship between gender and depression, and socialized gender roles had a greater explanatory power for rumination, neuroticism, and depression than did gender. Contrary to predictions, rumination did not mediate neuroticism's… more

Embedded monitors for detecting and preventing intrusions in cryptographic and application protocols.

Description: There are two main approaches for intrusion detection: signature-based and anomaly-based. Signature-based detection employs pattern matching to match attack signatures with observed data making it ideal for detecting known attacks. However, it cannot detect unknown attacks for which there is no signature available. Anomaly-based detection builds a profile of normal system behavior to detect known and unknown attacks as behavioral deviations. However, it has a drawback of a high false alarm rate… more
