Raped, beaten and bruised: military institutional abuse, identity wounds and veteran suicide

The Australian government has recently established a Royal Commission on Defence and Veteran Suicide (DVSRC). Veteran suicide rates for those who have left the Australian Defence Force (ADF) are higher than the national average and there has been little success in reducing this over an extended period of time. Veteran suicide is poorly understood, and the collected data is imprecise and incomplete. Deployment trauma and Post-traumatic stress disorder (PTSD i.e. a mental health lens) are taken for granted as the principal causes. This article presents a case study on institutional abuse in the ADF which led to the veteran attempting suicide on numerous occasions. The article draws upon the mental health and moral injury knowledge but questions their centrality and dominance. Military Institutional Abuse (MIA) and its consequent identity wounds are explained as institutional causes of military trauma. We argue that these institutional abuse processes and their consequences, occurring within military moral geographies, lead to suicidal ideation and attempt. These are situated within wider relations of civil society, the state, and the military

Dynamics of Dark-Bright Solitons in Cigar-Shaped Bose-Einstein Condensates

We explore the stability and dynamics of dark-bright solitons in two-component elongated Bose-Einstein condensates by developing effective 1D vector equations as well as solving the corresponding 3D Gross-Pitaevskii equations. A strong dependence of the oscillation frequency and of the stability of the dark-bright (DB) soliton on the atom number of its components is found. Spontaneous symmetry breaking leads to oscillatory dynamics in the transverse degrees of freedom for a large occupation of the component supporting the dark soliton. Moreover, the interactions of two DB solitons are investigated with special emphasis on the importance of their relative phases. Experimental results showcasing dark-bright soliton dynamics and collisions in a BEC consisting of two hyperfine states of $^{87}$Rb confined in an elongated optical dipole trap are presented.Comment: 4 pages, 5 figure

The definitive version was published in Marine Biology 156 (2009): 1049-1056, doi:10.1007/s00227-009-1149-6.Behavioral observations using a remotely operated vehicle (ROV) in the Gulf of California in March, 2003, provided insights into the vertical distribution, feeding and anatomy of the rare and delicate ctenophore Thalassocalyce inconstans. Additional archived ROV video records from the Monterey Bay Aquarium Research Institute of 288 sightings of T. inconstans and 2,437 individual observations of euphausiids in the Gulf of California and Monterey Canyon between 1989 and 2005 were examined to determine ctenophore and euphausiid prey depth distributions with respect to temperature and dissolved oxygen concentration [dO]. In the Gulf of California most ctenophores (96.9%) were above 350 m, the top of the oxygen minimum layer. In Monterey Canyon the ctenophores were more widely distributed throughout the water column, including the hypoxic zone, to depths as great as 3,500 m. Computer-aided behavioral analysis of two video records of the capture of euphausiids by T. inconstans showed that the ctenophore contracted its bell almost instantly (0.5 s), transforming its flattened, hemispherical resting shape into a closed bi-lobed globe in which seawater and prey were engulfed. Euphausiids entrapped within the globe displayed a previously undescribed escape response for krill (‘probing behavior’), in which they hovered and gently probed the inner surfaces of the globe with antennae without stimulating further contraction by the ctenophore. Such rapid bell contraction could be effected only by a peripheral sphincter muscle even though the presence of circumferential ring musculature was unknown for the Phylum Ctenophora. Thereafter, several live T. inconstans were collected by hand off Barbados and microscopic observations confirmed that assumption.Supported by the David and Lucile Packard Foundation and NOAA Grant #NA06OAR4600091

Beating dark-dark solitons in Bose-Einstein condensates

Motivated by recent experimental results, we study beating dark-dark solitons as a prototypical coherent structure that emerges in two-component Bose-Einstein condensates. We showcase their connection to dark- bright solitons via SO(2) rotation, and infer from it both their intrinsic beating frequency and their frequency of oscillation inside a parabolic trap. We identify them as exact periodic orbits in the Manakov limit of equal inter- and intra-species nonlinearity strengths with and without the trap and showcase the persistence of such states upon weak deviations from this limit. We also consider large deviations from the Manakov limit illustrating that this breathing state may be broken apart into dark-antidark soliton states. Finally, we consider the dynamics and interactions of two beating dark-dark solitons in the absence and in the presence of the trap, inferring their typically repulsive interaction.Comment: 13 pages, 14 figure

Validating the Postdischarge Surgical Recovery Scale 13 as a Measure of Perceived Postoperative Recovery After Laparoscopic Sacrocolpopexy

Objectives No postoperative recovery measurement tools have been validated among women undergoing laparoscopic sacrocolpopexy for pelvic organ prolapse, which impedes development and testing of strategies to improve recovery. The purpose of this study was to evaluate the performance of the Postdischarge Surgical Recovery Scale (PSR) as a measure of perceived recovery in laparoscopic sacrocolpopexy patients. Methods Women (N = 120) with stage 2 or higher pelvic organ prolapse undergoing laparoscopic sacrocolpopexy completed a 15-minute postoperative survey (days 7, 14, 42, and 90 [each ± 3 days]) which included the 15-item PSR. A confirmatory factor analysis was conducted using data from 14 days postsurgery, when patients would have begun to recover, but there was likely to be substantial variability in recovery across patients. We also assessed validity and explored sensitivity to change over time and minimally important difference values. Results Confirmatory factor analysis indicated a good fitting model for a reduced version of the PSR (ie, PSR13). Regressions showed that the PSR13 prospectively predicted single-item recovery scores. The PSR13 recovery significantly improved from days 7 to 42, suggesting the PSR13 is sensitive to change. Descriptive statistics including minimally important differences are reported. The minimally important difference was estimated to be around 5 points. Conclusions The PSR13 is a psychometrically sound tool for measuring recovery over time in this population. Its short length makes it an ideal postoperative recovery measure in clinical practice or research

If you could see what we see, would it bother you?

Objective The purpose of our study was to determine whether the anatomic threshold for pelvic organ prolapse (POP) diagnosis and surgical success remains valid when the patient sees what we see on exam. Methods Two hundred participants were assigned, by computer-generated block randomization, to see one of four videos. Each video contained the same six clips representative of various degrees of anterior vaginal wall support. Participants were asked questions immediately after each clip. They were asked: “In your opinion, does this patient have a bulge or something falling out that she can see or feel in the vaginal area?” Similarly, they were asked to give their opinion on surgical outcome on a 4-point Likert scale. Results The proportion of participants who identified the presence of a vaginal bulge increased substantially at the level of early stage 2 prolapse (1 cm above the hymen), with 67 % answering yes to the question regarding bulge. The proportion of participants who felt that surgical outcome was less desirable also increased substantially at early stage 2 prolapse (1 cm above the hymen), with 52 % describing that outcome as “not at all” or “somewhat” successful. Conclusion Early stage 2 POP (1 cm above the hymen) is the anatomic threshold at which women identify both a vaginal bulge and a less desirable surgical outcome when they see what we see on examination

Predictors of Postdischarge Surgical Recovery Following Laparoscopic Sacrocolpopexy: A Prospective Cohort Study

Objectives Our aim was to identify sociodemographic/clinical, surgical, and psychosocial predictors of postdischarge surgical recovery after laparoscopic sacrocolpopexy. Methods Study participants (N=171) with ≥ stage 2 pelvic organ prolapse completed a preoperative survey measuring hypothesized sociodemographic/clinical, surgical, and psychosocial recovery predictors followed by a postoperative survey at four time points (day 7, 14, 42, and 90) that included the Postdischarge Surgical Recovery (PSR)13 scale. One multivariate linear regression model was constructed for each time point to regress PSR13 scores on an a priori set of hypothesized predictors. All variables that had p values less than 0.1 were considered significant predictors of recovery because of the exploratory nature of this study and focus on model building rather than model testing. Results Predictors of recovery at one or more time points included the following: Sociodemographic/clinical predictors: older age, higher body mass index, fewer comorbidities, and greater preoperative pain predicted greater recovery. Surgical predictors: fewer perioperative complications and greater change in the leading edge of prolapse after surgery predicted greater recovery. Psychosocial predictors: less endorsement of doctors locus of control, greater endorsement of others locus of control, and less sick role investment predicted greater recovery. Conclusions Identified sociodemographic/clinical, surgical, and psychosocial predictors should provide physicians with evidence based guidance on recovery times for patients and family members. This knowledge is critical for informing future research to determine if these predictors are modifiable by changes to our narrative during the preoperative consultation visit. These efforts may reduce the postdischarge surgical recovery for patients with pelvic organ prolapse after laparoscopic sacrocolpopexy, accepting the unique demands on each individual’s time
