RESUMEN

The use of Insensitive Munitions eXplosives (IMX) is increasing as the Army seeks to replace certain conventional munitions constituents, such as 2,4,6-trinitrotolene (TNT), for improved safety. The IMX formulations are more stable and therefore less prone to accidental detonation while designed to match the performance of legacy materials. Two formulations, IMX 101 and 104 are being investigated as a replacement for TNT in artillery rounds and composition B Army mortars, respectively. The chemical formulations of IMX-101 and 104 are comprised of four constituents;2,4-dinitroanisole (DNAN), 3-nitro-1,2,4-triazol-5-one (NTO), 1-nitroguanidine (NQ), and Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) which are mixed in various ratios to achieve the desired performance. The current work details the analysis of the IMX constituents by single column HPLC-UV-ESI-MS. Detection limits determined are in agreement with similar HPLC analysis of compounds, ranging from 7 to 9µg/L. Gradient mobile phases are used to allow separation of the 4 target compounds in more complex mixture of other concomitant compounds. Mass spectra are used to confirm analyte identity with chromatographic retention time.

RESUMEN

Investigated the Rorschach characteristics of 28 mothers of incest victims, using the Rorschach Comprehensive System. Their characteristics were compared to those from a control group of 28 women, matched with the target group for socioeconomic status (SES), age, education, marital status, and the presence of children. Chi-square, analysis of variance, and a stepwise linear discriminant function analysis were used to evaluate Rorschach differences between the control and target groups. Major findings indicate that mothers of incest victims demonstrated significantly greater weaknesses in reality testing, more frequent signs of depression, and greater interpersonal guardedness than control group mothers. Discriminant function analysis, based on scores from the schizophrenia index (SCZI), conventional form (chi + %), and texture responses (t), yielded an overall accurate classification rate of 87.5% for placement of women into the target and control group categories.

RESUMEN

The Sexual Decision-Making Inventory (SDMI) was developed to measure levels of sexual decision making based on the developmental concepts of Object Relations Theory. The inventory asks subjects to report on their thoughts and feelings at the time they decided to have sex in their most recent sexual relationship. The inventory was tested in a pilot study involving 45 male and 49 female undergraduates. A factor analysis was performed on the SDMI and six levels of sexual decision making were defined: Object Constancy, Ambivalence, Need for Merger, Need Gratification, Low Self-esteem, and Narcissistic Gratification. Endorsement of items on these subscales was related to perceptions of the relationship. In a second study involving 79 male and 135 female undergraduates, subjects completed the SDMI, the Bell Object Relations Self-report Inventory, and a questionnaire concerning perceptions of the relationship in which the sexual decision was made. Object Constancy was positively correlated to object relations, satisfaction with the relationship, and durability of the relationship; Ambivalence, Need Gratification, and Low Self-esteem were negatively correlated with object relations, satisfaction with the relationship, and durability of the relationship; Narcissistic Gratification was negatively correlated with object relations and most aspects of the relationship with interesting exceptions such as sexual satisfaction. Sex differences demonstrated that females were more likely to endorse items on the Object Constancy subscale; whereas males were more likely to endorse items on the Ambivalence, Need Gratification, and Narcissistic Gratification subscales. There were no sex differences, however, in quality of general object relations.

RESUMEN

Naturalistic observations were made while the author was living and working in Poland as a visiting professor at the Institute of Psychology, Warsaw University, from October through December 1981. Social, political, economic, and interpersonal elements of the Polish "crisis" and reactions of the Polish people to these stressors are described. Individual patterns of coping with stress are categorized in terms of people's beliefs about the causes of stress and beliefs about personal control over the causes of stress. Three groups are identified: People who were certain that they could or could not modify the causes of stress and, therefore, coped by taking action ("fight" or "flight"); people who were uncertain about their capacity to modify the causes of stress, but believed that they could manage their daily lives; and people who believed that their only realm of influence was over intrapsychic events and coped via control over intake of information (repression or sensitization). The relative success of the different coping strategies is considered. Finally, the imposition of martial law and people's reactions to it are described.
