Assessment of Occupational Burnout in United States Air Force Predator/Reaper “Drone” Operators

This study investigates the self-reported levels of occupational burnout among 1,094 U.S. Air Force drone operators stationed within the borders of the United States who are supporting a wide range of around-the-clock military surveillance and weapons strike missions across the globe. Data were gathered from a Web-based survey of demographic items and the Maslach Burnout Inventory assessing the facets of occupational burnout (exhaustion, cynicism, and professional efficacy). The overall survey response rate was 49%. Approximately 20% reported high levels of exhaustion, and 11% reported high levels of cynicism, but only 3% reported low levels of professional efficacy. Predictors of exhaustion, as well as between group differences, were identified along with recommendations for performance improvement and mitigating risks to safety.     

Advantages of Rhythmic Movements at Resonance: Minimal Active Degrees of Freedom,Minimal Noise,and Maximal Predictability

Using time delay embedding, the authors applied phase space reconstruction to the time series of rhythmic movements of a hand-held pendulum. Subjects (N = 6) produced the manual oscillations about the wrist at the pendulum's resonant frequency and at a higher and a lower frequency. The number of active degrees of freedom required to capture the dynamics of the rhythmic behavior was 3 for the resonant frequency and 4 for each of the nonresonant frequencies. The residual high-dimensional noise was similarly lowest for the resonant frequency. Whereas 33% and 20%, respectively, of the vectors in the phase spaces of the dynamics higher and lower than resonance were unpredictable, only 12% were unpredictable at resonance. Finally, the predictability of the evolving dynamics extended farther into the future for oscillations at the resonant frequency. At resonance, the prediction horizon was 5 times farther than the prediction horizon for the higher than resonance behavior and 2.5 times farther than that for the lower than resonance behavior. The results suggest that, in pendular oscillations of a limb or limb segment, attunement of the central nervous system to the resonant frequency minimizes the variables to be controlled and maximizes the predictability of the rhythmic movement's chaotic dynamics.     

What can subjective forgetting tell us about memory for childhood trauma?

In the present study, we examined the prevalence and predictors of subjective forgetting (i.e., self-reported amnesia) of child sexual abuse (CSA). Adults who, as children, were involved as victims in legal prosecutions were questioned about their CSA experiences, which had been documented in the 1980s, and about lost and recovered memory of those experiences. Males and individuals who experienced more severe abuse were more likely to report forgetting. The majority of individuals attributed their forgetting to active attempts to avoid thinking about the abuse. In contrast, when predictors of subjective forgetting were used to predict objective memory of abuse, more severe abuse and more extended legal involvement were associated with fewer memory errors. The differences between subjective and objective memory underscore the risks of using subjective measures to assess lost memory of abuse.     

Toni Morrison's Beloved: A Journey through the Pain of Grief

This paper elucidates the structure of Toni Morrison's novel, Beloved, using the framework of human emotions in response to grieving and death as developed by Elisabeth Kubler-Ross. Through her studies of terminally ill patients, Kubler-Ross identified five stages when approaching death: denial and isolation, anger, bargaining, depression and acceptance. These stages accurately fill the process that the character Sethe experiences in the novel as she learns to accept her daughter's death.     

Empirical evidence supporting the conceptual relatedness of object representations and internal working models

The proliferation of new developmental and clinical theories broadly termed "psychoanalytic" demands a methodology for making systematic comparisons to establish the commonalities and distinctions among them. This article presents an empirical method for the comparative evaluation of such theories. The Mother-To-Child Object Representation / Internal Working Model Q-sort is a 100-item instrument constructed to assess the quality of the prototypical mother's object representation and internal working model of her child at age five. Object relations judges were asked to sort these items for a complex, differentiated, integrated object representation of a five-year-old, attachment judges for a secure, coherent, freely valuing internal working model of a five-year-old. Judges' criterion Q-sorts in each group yielded a composite criterion Q-sort of the quality of the prototypical mother's mental representation of her child according to each group's theoretical perspective. The Spearman-Brown correlation between the two composite criterion Q-sorts was r = .90, p < .001 , suggesting that when confined to a 100-item common vocabulary, judges representing each theoretical construct agreed on the conceptual relatedness of object representations and internal working models. The theoretical constructs of object representations and internal working models share common assumptions in need of further exploration.     

Traumatic impact predicts long-term memory for documented child sexual abuse

Prospective studies of adults' memories of documented child sexual abuse (CSA) reveal that the majority of individuals remember their victimization. However, the accuracy of these memories has rarely been investigated scientifically. The present study examined predictors of memory accuracy and errors 12 to 21 years after abuse ended for individuals with legal experiences resulting from documented CSA. Severity of posttraumatic stress disorder (PTSD) symptomatology was positively associated with memory accuracy. However, individuals nominating CSA as their most traumatic life event exhibited relatively accurate memory regardless of indicators of PTSD. Predictors of memory errors were also identified (e.g., less maternal support). These results indicate that, in addition to understanding the role of traditional cognitive factors, understanding an event's traumatic impact is important for predicting the accuracy of long-term memory for reported CSA.     

Reliability and validity of the Yale Global Tic Severity Scale

To investigate the reliability and validity of the Yale Global Tic Severity Scale (YGTSS), 28 youth aged 6 to 17 years with Tourette's syndrome (TS) participated in the study. Data included clinician reports of tics and obsessive-compulsive disorder (OCD) severity, parent reports of tics, internalizing and externalizing problems, and child reports of depression and anxiety. All children participated in a 2nd YGTSS administration by the same rater 48 days later. Good internal consistency and stability were found for the YGTSS scores. YGTSS scores demonstrated strong correlations with parent-rated tic severity (r = .58-.68). YGTSS scores were not significantly related to measures of clinician ratings of OCD severity (r = .01-.15), parent ratings of externalizing and internalizing behavior (r = -.07-.20), and child ratings of depression (r = .02-.26) and anxiety (r = -.06 -.28). Findings suggest that the YGTSS is a reliable and valid instrument for the assessment of pediatric TS.     

A Theoretical Framework for Understanding Help-Seeking Processes Among Survivors of Intimate Partner Violence

This paper suggests a conceptual framework for understanding the processes of help-seeking among survivors of intimate partner violence (IPV). A cognitive theory from general literature on help-seeking in “stigmatizing” situations suggests three relevant processes or stages of seeking help in the IPV context: defining the problem, deciding to seek help, and selecting a source of support. Individual, interpersonal, and sociocultural factors that influence decision-making at each of these stages are discussed and illustrated with case examples.
