The idea that the human mind-that faculty of the intellect which we use to define and discern the truth-might also be used to deceive itself is not new. The classic orator Demosthenes warned of this possibility in 349 B.C. when he wrote that "Nothing is more easy than to deceive one's self; what a man wishes he generally believes to be true." 1 Even Jean Jacques Rousseau, who suggested the possibility of man as "noble savage," alerts us to this paradox, when he writes "Jamais fa nature ne nous trompe; c'est toujours nous qui nous trompons" ("Nature never deceives us; it is always we who deceive ourselves). 2 But it was Sigmund Freud who placed this idea firmly into the field of psychopathology and then, later, into a general psychological theory. According to Freud, understanding the function of a defense mechanism means not only fathoming the origin of pathological symptoms but also comprehending a model of the mind that includes both conscious and unconscious mental processes. From this initial focus on the general process of defense, Freud and his followers went on to identify various forms this process might take, with the result that today we have a list of 3 more than 37 defense mechanisms described in the literature.

What is the scientific status and the "truth value" of the concept of defense mechanisms? Among contemporary psychologists, three types of answers to this question may be expected. Some would wholeheartedly endorse the theoretical, clinical, and research value of this notion; others would reject it outright. Between these two extremes, a large number of observers, perhaps the majority, would suspend their judgment. Their attitude, compounded of hope and doubt, would capitalize on defense as an interesting and promising concept. At the same time, these psy chologists would express skepticism and disappointment over its clinical limitations, theoretical ambiguity, and research failures. The present volume is primarily addressed to the audience of hopeful skeptics-those who have not given up on the notion of defense, yet have been frustrated by the difficulties of incorporating it into the modern, streamlined structure of psychology. To this end, we have brought together theoretical and empirical contributions germane to defense together with reports about their applications to clinical and personality assessment, especially in relation to psychopathology, psychosomatics, and psycho therapeutic intervention.

In tracing the rise of the modern idea of the American "new woman," Lynn Dumenil examines World War I's surprising impact on women and, in turn, women's impact on the war. Telling the stories of a diverse group of women, including African Americans, dissidents, pacifists, reformers, and industrial workers, Dumenil analyzes both the roadblocks and opportunities they faced. She richly explores the ways in which women helped the United States mobilize for the largest military endeavor in the nation's history. Dumenil shows how women activists staked their claim to loyal citizenship by framing their war work as homefront volunteers, overseas nurses, factory laborers, and support personnel as "the second line of defense." But in assessing the impact of these contributions on traditional gender roles, Dumenil finds that portrayals of these new modern women did not always match with real and enduring change. Extensively researched and drawing upon popular culture sources as well as archival material, The Second Line of Defense offers a comprehensive study of American women and war and frames them in the broader context of the social, cultural, and political history of the era.

Vulnerability analysis, also known as vulnerability assessment, is a process that defines, identifies, and classifies the security holes, or vulnerabilities, in a computer, network, or application. In addition, vulnerability analysis can forecast the effectiveness of proposed countermeasures and evaluate their actual effectiveness after they are put into use. Vulnerability Analysis and Defense for the Internet provides packet captures, flow charts and pseudo code, which enable a user to identify if an application/protocol is vulnerable. This edited volume also includes case studies that discuss the latest exploits.

"Joseph Fernando provides the first in-depth exploration and up-to-date revision of the psychoanalytic theory of defenses since Anna Freud's 1936 classic, The Ego and the Mechanisms of Defense. The workings of three basic forms of defense - repression, denial, and post-traumatic defenses - are clearly described and illustrated with examples from Dr. Fernando's clinical practice, and new concepts including the zero process, contrast defenses, and compound defenses are introduced." --Book Jacket.
