Behavioral sequelae of exposure to high power microwave fields

Behavioral sequelae of exposure to high peak power microwave pulses, similar to those produced by operational radar systems and experimental, directed energy weapons systems, were studied using rats trained on fixed-ratio, variable-interval, and differential reinforcement-of-low rate schedules. Ten minute exposures to 240, 720, 2160, and 6480 pulses at a 1 Megawatt peak power level caused a rectal temperature rise of 0.7 to 2.5°C in the animals. Regardless of their schedule of reinforcement, animals exposed to the highest dose level failed to respond, on the average, for 13 minutes after the exposure when they were placed in operant conditioning chambers. However, as soon as their rectal temperatures decreased, responding resumed and no further changes in response pattern were exhibited. No long-term effects were observed in exposed animals. Thus, the behavioral effects that were seen were thermal in nature and independent of the pulsed nature of the fields.

The shifting salience of valence and instrumentality in the prediction of perceived effort,satisfaction and turnover

The role of valence and instrumentality was examined in predicting three work-related criteria in a military setting: satisfaction, perceived effort, and turnover. A total of 323 enlisted men responded to desirability and instrumentality scales for each of four categories of performance outcomes: extrinsic rewards, personal fulfillment, recognition, and autonomy. Multiple regression analyses indicated that the different outcome types varied substantially in their relationship to the criteria, ranging from strongly positive to no relationship to strongly negative. Furthermore, the salience of valences and instrumentalities changed as a function of the criterion being predicted in a manner not deducible from current expectancy-valence models. Several implications of the results were discussed in terms of assumptions underlying general expectancy-valence approaches to motivation.This research was supported in part by Grant DAHC19-77-G0017 to New York University (Samuel Shiflett, principal investigator) from the Army Research Institute for the Behavioral and Social Sciences.

The detailed method of optimal regions

The detailed method of optimal regions is an extended form of the method of optimal regions which has been found effective in solving the personnel classification problem when the number of job categories is small. The automatic determination of the successive values of thev _i , made possible by the more exact techniques of the detailed method, provide easier solutions for the more complex problems and provide solutions, which, for the most part, can be mechanized. In a sense the detailed method of optimal regions is more than a detailed form of the method of optimal regions. It is essentially a method of transformations by which the original matrix is reduced to a matrix from which the solution is easily obtained.Much of the basic research covered in this paper was carried out while the author was working on the problem of personnel classification in his capacity as Consultant, Personnel Research Branch, Department of the Army.

Organizational reward systems: Implications for climate

This study investigated the role of systematically different organizational reward structures upon individual perceptions of the reward climate. Nurses in a naval hospital worked for the same supervisors but were subject to either tenure-contingent (N=73) or behavior-contingent (N=50) reward systems. No differences in perceived reward climate were found between the two groups. In the tenure-contingent group, job attitudes reflected individual characteristics rather than perceived climate. The opposite relationship was found for the behavior-contingent group.Support for this research was provided under Office of Naval Research Contract RR942-08-01 NR 170-915.

Solution of the personnel classification problem with the method of optimal regions

The personnel classification problem is identified mathematically with other problems in the social and biological sciences. This mathematical problem is shown to be a special case of the general mathematical problem of linear programming. It is proposed here that the personnel classification problem may be solved directly by methods particularly appropriate to it as well as by the simplex method, which is a standard method for solving the general linear programming problem. The method of optimal regions is derived and illustrated in this paper.Much of the basic research covered in this paper was carried out while the author was working on the problem of personnel classification in his capacity as Consultant, Personnel Research Branch, Adjutant General's Office, Department of the Army.

Children’s awareness and understanding of dangers at home

This study concerns children’s awareness and understanding of dangers at home. Children aged five to seven years responded to photographs depicting child models exposed to a range of dangers which may be encountered at home—involving the road, a cooker (stove), a knife, electricity, fire, medicine and climbing. Generally, the children were found to be well aware of the dangers in all the circumstances, with small age effects noted for the road, medicine, climbing, cooker and knife situations. Understanding of the consequences of exposure to danger varied across situations and a tendency to underestimate the seriousness of the potential harm was noted. This research was conducted while the author was a Visiting Research Fellow at the Department of Psychology, University of Leeds and was supported by a University of Leeds Senate Research Grant to Professor A.J. Chapman.     

Women in the United States Army

This article addresses the recent increase in the utilization of women in the United States Army. It traces the history of women in the Army from the turn of the twentieth century to the present and recounts research (both published and unpublished) concerning (1) attitudes toward the use of women in the Army, (2) the impact the changing role of women has had on the Army's ability to perform its mission, and (3) the adjustment of women to the Army. Finally, the author speculates about the future of women in the Army.This article is a revised version of a paper presented at the meeting of the Southwest Regional Conference Inter-University Seminar on Armed Forces and Society, Dallas, April 1978.

Reliability of the Attitudes Toward Women Scale (AWS) and the Personal Attributes Questionnaire (PAQ)

The stability and internal consistency of Spence and Helmreich's Attitudes Toward Women Scale (AWS) and Personal Attributes Questionnaire (PAQ) are reported. An entire first-year class of 1,007 male and 78 female cadets at the U.S. Military Academy were given a battery of psychological tests before and after cadet basic training, a 2 1/2-month period. The AWS and PAQ proved to be highly reliable, comparable to other frequently used psychological tests. This psychometric information encourages researchers to make further use of these gender-related instruments.This research was conducted under research grants from the Army Research Institute (Alan G. Vitters and Jerome Adams, Principal Investigators).

A significance test for one parameter isosensitivity functions

A large-sample test for the significance of the difference between two detection data points is developed based upon the assumptions of a one-parameter signal detectability model. In essence, the null hypothesis tested is that two observed data points belong to the samed' function.Portions of this research were supported by Contract DA-49-193-MD-2713 between the University of Washington and the U.

The effects of virtual nature exposure on pro-environmental behaviour

Exposure to (virtual) natural environments may encourage people to care about environmental protection and to engage in pro-environmental behaviour. Previous research on this effect produced inconsistent results, suggesting that it may depend on the type of nature and behaviour under study. In the present study (N = 266), we investigated nature exposure effects on effortful pro-environmental behaviour in an online experiment. After watching pictures of either intact or destroyed natural environments, participants could exert voluntary extra efforts to generate real donations to an environmental organisation. In comparison to the intact nature condition, participants exerted significantly more effort for environmental protection after being exposed to pictures of destroyed nature. No clear differences were observed between the nature exposure conditions and a no-picture control condition. These findings illustrate the complexity of nature exposure effects and suggest that different types of nature exposure may differentially affect people's pro-environmental behaviour.     

Borderline and schizophrenic patients: A comparison using the MCMI-II

In the present study we examined the Millon Clinical Multiaxial Inventory-II scores of psychiatric patients with a diagnosis of either borderline personality disorder (BPD;n=13) or schizophrenia (n=13). The analyses revealed that the BPD patients were significantly elevated on a number of scales in addition to the Borderline scale. The second goal of this study was to assess the discriminative validity of the Borderline and Thought Disorder Scales with both base rate (BR) cutoffs and the number of endorsed prototypic items. The Borderline scale demonstrated the most diagnostic power when using BR cutoffs, whereas the Thought Disorder scale performed poorly, no better than chance levels, with all cutoffs.This research was supported by Social Sciences and Humanities Research Council of Canada Grant 410-89-0335 and by a grant from the Department of Research and Programme Evaluation, Brockville Psychiatric Hospital.

Computer software patents: Some perspectives and misunderstandings

The importance that in-house software plays today in many organizations is without question. Perspectives of efficiencies, effectiveness, competitive advantage, and so on are but three areas where such applications exist. Many organizations have adopted measures to protect such software as a specific type of intellectual property. In the 1990s quite often the form of protection taken is software patents. The understanding and enthusiasm about software patents that is exhibited by organizations is not often shared by information systems researchers, however. For the most part, IS researchers dismiss software patents as an appropriate protective measure. This paper presents some background on patents and their applicability to software. Some US and international perspectives are also discussed to provide the reader with a somewhat broader perspective. We then discuss several IS research endeavors that either dismiss patents, or treat them incorrectly. We conclude with a research agenda for IS researchers. the Department of Computer Information Systems & Quantitative Analysis, University of Arkansas.

His research has been published in Information Systems Research, MIS Quarterly, and the Journal of Management Information Systems. Her current research is focused on interogranizational systems and the human relationships that exist in parallel to these systems.     

The effect upon simple animal behavior of different frequencies of reinforcement, Part II: separate control of the reinforcement of different IRTs

Rats' responding was stabilized for over 35 days on 4-min variable-interval reinforcement. Reinforcements per hour for 4-sec wide classes of interresponse times were then separately controlled by adjusting those for each class to the variable-interval values that had just prevailed. This produced little or no change in interresponse times, indicating that the new procedure was substantially equivalent to a variable-interval schedule. The variable-interval schedule produced a high and stable conditional probability of interresponse times in the 0- to 4-sec class, associated with a peak in reinforcements per hour for this class. Reducing the reinforcements per hour for this class while raising that for another class (by 3.3 reinforcements per hour) significantly reduced the conditional probability of 0- to 4-sec interresponse times. Restoring the 3.3 reinforcements per hour to the 0- to 4-sec class significantly elevated the conditional probability of interresponse times in this class. Hence, it is concluded that the distribution of interresponse times produced by a subject during some variable-interval schedules is determined partly by the relative reinforcement of different interresponse times that the variable-interval schedule provided.Reprinted from Part II of the Final Report of Research under Contract DA-49-007-MD-408 with the Medical Research and Development Board, Office of the Surgeon General, Department of the Army, 31 December 1954.

A correction for replicated error in correlation coefficients

A solution is presented to the problem of determining a proper correction for spuriousness in correlation coefficients. The general case developed is the estimate of correlation betweenu andv, both being linear functions of the same set of variables. Special formulae relate to overlapping scales correlations, part-whole correlations, and item-total test correlations.The research and development reported herein was performed pursuant to a contract with the United States Department of Health, Education, and Welfare, Office of Education, under the provisions of the Cooperative Research Program.

Accuracy of Pace Count as a Distance Estimation Procedure

The purpose of this study was to assess the accuracy of pace counting under varying conditions and to resolve discrepancies between U.S. Army Field Manual 21-26 (FM 21-26; Department of the Army, 1987) and pace-counting research conducted by Powers (1964). Two experiments were designed to measure accuracy of distance estimations from pace counting on-road and off-road under conditions of daylight and darkness. In both experiments, male soldiers enrolled in One Station Unit Training (OSUT) were trained to estimate distances based on pace counts performed on a flat road during daylight. In Experiment 1, the soldiers were tested on a flat road during both daylight and darkness; in Experiment 2, soldiers were tested off-road on hilly terrain during both daylight and darkness. The general finding in both experiments was that soldiers tended to underestimate distance during day- light and to overestimate distance during darkness. These errors became greater as the test conditions became less like the training condition. It was concluded that pace count should be adjusted, as indicated by FM 21-26, either by opportunities for more training time or by standard pace-count adjustment formulas. Also, because of inherent inaccuracies, pace count should be used as a backup and/or in conjunction with other land navigation techniques.     

Preliminary Development of Trauma-Focused Treatment Groups for Incarcerated Juvenile Offenders

Summary

Most male juvenile offenders have been exposed to trauma. Many juvenile offenders have experienced both acute and chronic trauma. Trauma exposure among offenders is closely linked to their criminal behavior, yet few protocols have been developed to treat posttraumatic sequelae in a delinquent population. This article describes initial efforts to develop group therapy services for incarcerated male juvenile offenders who have histories of significant trauma exposure and current symptoms of PTSD. Four separate pilot groups were conducted in two Massachusetts Department of Youth Service secure residential facilities. The treatment included trauma psychoeducation (including the relationship between trauma and offending), therapeutic trauma exposure through discussion and expressive arts, and coping skill development. The treatment development and initial implementation as well as directions for future research are discussed.     

Next Steps in Research on Children Exposed to Domestic Violence

The papers in this special issue of Clinical Child and Family Psychology Review provided an overview of what is known about children's exposure to domestic violence, and include indications of gaps in extant research. These gaps and research needs are summarized in this conclusion. Specifically, there is need for further research in several broad areas: definition and measurement of children's exposure to domestic violence; development of research methods and statistical designs that provide detailed information and provide for evidence of intervention effectiveness; impact of domestic violence on parenting and family functioning; the role of child factors and exposure to violence factors in predicting developmental risk and resilience; medical and health consequences of exposure to violence; and the nature of child-system interaction in response to domestic violence. Research needs in these areas are discussed in greater detail, and specific questions are raised for further development.     

On the use of bisection procedures in animal psychophysical scaling

The ability of bisection procedures to specify the form of the psychophysical scale depends upon the precision of the technique. It is demonstrated that the precision of bisection techniques is a function of the stimulus interval bisected. Consequently, the choice of stimuli in a bisection experiment may predispose the ability of the experiment to distinguish between alternative psychophysical scales. The testing of interval scale properties of derived scales and the assessment of context effects in bisection experiments was also discussed.This material has been reviewed by the Walter Reed Army Institute of Research, and there is no objection to its presentation and/or publication.
