Mass traumatic terror in Oklahoma City and the phases of adaptational coping,part I: Possible effects of intentional injury/harm on victims' post-traumatic responses

The bombing in Oklahoma City shook the entire nation from “sea to shining sea.” This tremendous collective sensation was made even worse when available evidence revealed that this act of terrorism had not been committed by some terrorist from the Middle East but one from Middle America. The blast stunned the nation's sense of collective safety, while it raised serious questions about our ability as a nation to manage violence, and the profound feelings of discontent and narcissistic injuries among distressed Americans. Was it this failure to address chronic discontents that led to this tragedy of mass violence? These larger sociocultural and political issues are being debated in public and private forums throughout the nation, an activity that is likely to continue for some time to come. As these issues are debated in the public arena, victims' levels of psychological distress are expected to rise, as they attempt to process the traumatic shock in their minds and bodies. Specifically, this article has two parts and focuses on acute and post-acute psychophysiological traumatic stress responses in victims, as well as issues pertaining to assessment, prevention, and treatment. Part I addresses the nature of disasters, with a special emphasis on the victim's subjective evaluation (meaning) of the reality of a catastrophe caused by intentional human strategy. The article, additionally, discusses issues of epidemiology of stress reactions, post-traumatic stress disorder, co-morbidity, risk factors, and assessment and diagnostic considerations. Part II, to be published in the next of issue of the Journal, will focus on issues of prevention as well as post-disaster intervention. Prevention of chronic post-traumatic stress disorder after the Oklahoma City bombing is a critical objective by debriefers and mental health professionals. A proposed four-phase model called “self-efficacy adaptational coping” will be presented in Phase II as well. The present article is probably the first major discussion on the traumatic effects of the blast on individuals, families, and the communities of Oklahoma City, and the first to offer some broad guidelines to intervention. Since it predates future empirical studies, the author relies on his almost 20 years of experience in the field of traumatic stress, and on a review and integration of pertinent disaster outcome studies in the national and international literature.     

Controlling the Ground Reaction Force During Lifting

The control of the ground reaction force vector relative to the center of gravity (CoG) was examined while subjects performed a back-lifting task. Six male subjects (aged 24.0 +/- 2.5 years) repeatedly lifted a barbell. A biomechanical analysis that used a linked segment model revealed that the summed rotations of body segments during lifting yielded a specific rate of change of the angular momentum of the entire body. This equaled the external moment provided by Fsubg; relative to CoG. This implies that multisegment movements involve control of the angular momentum of the entire body through an appropriately directed Fsubg;. Thus, in dynamic tasks Fsubg; is pointed away from rather than lined up with the CoG, as is the case in static tasks.     

Creative Problem-Solving in Art: A Model for Idea Inception and Image Development

A model for creative problem-solving specific to the creation of art is proposed. The development of the Osborn-Parnes and Isaksen-Treffinger models are reviewed. An adaptation of the Osborn-Parnes/Isaksen-Treffinger models is presented. The Model for Idea Inception and Image Development in Art is presented with five primary stages: Associative Exploration, Problem Parameter Exploration, Multiple Focus Exploration, Primary Focus Exploration and Refinement. Transitional stages are delineated. The significance and implications of the model for artists, students and instructors in art education are discussed.     

Achievement motivation in relation to achievement-related recall,performance, and urine flow,a marker associated with release of vasopressin

Administration of the pituitary hormone, arginine vasopressin (AVP), enhances memory in animals and humans. Since AVP is the antidiuretic hormone, its release can be inferred from reductions in urine flow. Forty-six male adults recalled the contents of a complex story and then either were exposed to achievement arousal or were not. Significantly more of the subjects in the aroused than the nonaroused condition showed a decrease in urine flow, and the greater the decrease in urine flow among the achievement-aroused subjects, the better the recall of achievement-related story content 24 hours later. Subjects high inn Achievement, in the achievement-oriented condition, showed lower urine output at the outset of the second day and greater improvement in learning to unscramble words. Since lower urine output was also related to improvement in unscrambling words, achievement arousal may have released AVP which in turn may have facilitated achievement-related retention and performance.I am greatly indebted to Sean Connelly for assistance in carrying out this research and to Dr. Franklin Epstein of the Beth Israel Hospital, Boston, for helping me to understand how the kidney functions in producing urine.
