This study explored the journey of American armed forces personnel from their decision to join the service, through their service in an active military conflict and how these factors may be associated with potential resistance for mental healthcare. The data came from qualitative interviews with 46 OIF/OEF/OND active-duty military, reservists, and discharged veterans of the average age of 25 years, who presented for a new episode of mental health treatment to a large Veterans Affairs Hospital (VAH) in Northeastern United States in 2011-2012. Qualitative analysis of veterans' perceptions revealed several major themes describing how a mental health diagnosis would negatively impact both their sense of identity and pragmatic career-building goals: enlisting as a career-building avenue, 'noble superhero' identity, escaping from hardship, and mental illness as a career-killer. Findings suggest that factors making young veterans resist mental healthcare may be reduced by partnering VAH psychiatrists with career counselors, and by enhancing military leadership's awareness and understanding about how to support soldiers with emotional and mental health needs, with a goal to eliminating stigma.
Planning for future water resource management in a warming climate is confounded when an expectation of increasing evaporation from open water surfaces with global warming is contradicted by observations of secular declines of pan evaporation. Decreasing pan evaporation has been observed globally – a trend which has been attributed variously to declines in wind run (‘global stilling’), declines in radiation (‘global dimming’) and increases in ambient humidity. This contrast between expectation and observation is known as the ‘evaporation paradox’. We evaluated trends in Symons pan evaporation from 154 pans across South Africa. Whilst 59 pans (38% of the 154) showed a statistically significant decrease in observed evaporation rates (p≤0.05), 30 (20%) showed an increase, and 65 (42%) showed no change. These results do not support simple attributions of trends to a common global cause. There is no spatially coherent pattern to trends across South Africa, suggesting that shifts in local drivers of evaporation confound expectations of secular trends due to global drivers. Changes in fetch conditions of the Symons pan installations may be implicated, whereby increasing tree density (through afforestation, alien plant invasion and woody thickening) increases surface friction, reducing wind run, and/or irrigation nearby, increasing local humidity. Correct attribution of the evaporation paradox to reduced wind run in South Africa must consider changing local conditions. Increased tree cover has been observed near a third of the South African Symons pans. Observed evaporation increases for one fifth of pans may implicate expected global drivers for pans where local fetch conditions have remained relatively constant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
