Mental health treatment seeking by military members with posttraumatic stress disorder : findings on rates, characteristics, and predictors from a nationally representative Canadian military sample

Objective: The goal of this study was to identify rates, characteristies, and predictors of mental health treatment seeking by military members with posttraumatic stress disorder (PTSD). Method: Our sample was drawn from the 2002 Canadian Community Health Survey-Canadian Forces Supplement (CCHS-CF) dataset. The CCHS-CF is the first epidemiologic survey of PTSD and other mental health conditions in the Canadian military and includes 8441 nationally representative Canadian Forces (CF) members. Of those, 549 who met the criteria for lifetime PTSD were included in our analyses. To identify treatment rates and characteristics, we examined frequency of treatment contact by professional and facility type. To identify predictors of treatment seeking, we conducted a binary logistic regression with lifetime treatment seeking as the outcome variable. Results: About two-thirds of those with PTSD consulted with a professional regarding mental health problems. The most frequently consulted professionals, during both the last year and lifetime, included social workers and counsellors, medical doctors and general practitioners, and psychiatrists. Consultations during the last year most often took place in a CF facility. Treatment seeking was predicted by cumulative lifetime trauma exposure, index traumatic event type, PTSD symptom interference, and comorbid major depressive disorder. Those with comorbid depression were 3.75 times more likely to have sought treatment than those without. Conclusions: Although a significant portion of military members with PTSD sought mental health treatment, 1 in 3 never did. Trauma-related and illness and (or) need factors predicted treatment seeking. Of all the predictors of treatment seeking, comorbid depression most increased the likelihood of seeking treatment.

Between pragmatism and the defence of a “Sister State” : the national association for the advancement of colored people and the U.S. occupation of Haiti, 1915-1922

À l’origine, la nouvelle concernant l’occupation américaine d’Haïti en 1915 a suscité peu d’indignation aux États-Unis. En effet, on reproche à la république son instabilité politique et on juge aussi qu’une intervention américaine concourrait à l’édifice de l’autorité de la loi. À partir de 1915 et surtout en 1920, l’Association nationale pour l’avancement des gens de couleur (NAACP), fondée en 1909, critique cette ingérence et milite pour y voir un terme. W.E. B. Du Bois et James Weldon Johnson, deux figures publiques noires importantes travaillant au sein de l’organisation, dénoncent avec conviction l’occupation d’Haïti. Les historiens ont jusqu’ici jugé que la NAACP fut inspirée par des considérations de solidarité raciale en adhérant à la cause de la souveraineté haïtienne. Si la thèse présente ne réfute pas cette possibilité, elle cherche tout de même à démontrer que le cadre conceptuel de la solidarité raciale ne saurait illustrer toute la complexité de la campagne haïtienne érigée par la NAACP. Par conséquent, une attention dirigée davantage sur le contexte social et politique américain entre 1915 et 1922 révèle que pour la NAACP, la dénonciation de l’occupation américaine d’Haïti représentait d’une part une opportunité de discuter des problèmes sociaux touchant les Afro-Américains, et d’autre part, une occasion de renforcer sa position aux États-Unis.

Influence of occupation number of single particle levels on K - K charge transfer in collisions of 90 keV - Ne{^9+} on Ne

The influence of the occupation of the single particle levels on the impact parameter dependent K - K charge transfer occuring in collisions of 90 keV Ne{^9+} on Ne was studied using coupled channel calculations. The energy eigenvalues and matrixelements for the single particle levels were taken from ab initio self consistent MO-LCAO-DIRAC-FOCK-SLATER calculations with occupation numbers corresponding to the single particle amplitudes given by the coupled channel calculations.

Estudio de seguimiento de las audiometrías de los años 2009, 2010 y 2011 de los pilotos de las fuerzas militares

La audición es el segundo mecanismo sensorial más importante después de la visión para obtener información durante la operación de una aeronave. Les permite a los pilotos percibir, procesar identificar los sonidos del ambiente que los rodea. Así necesita oír bien tanto en vuelo como en tierra, especialmente entre 500 y 3000 Hz para la recepción del lenguaje hablado y de las señales auditivas. Objetivo: Determinar los cambios progresivos en el tiempo y las frecuencias auditivas que se afectan en las audiometrías de los pilotos militares de las fuerzas militares en los años 2009, 2010 y 2011. Material y Métodos: Se trata de un estudio longitudinal de cohorte en el cual se identificará el comportamiento de las audiometrías de la población de pilotos de las fuerzas militares de Colombia en los años 2009, 2010 y 2011. Se hará una revisión retrospectiva de dichas audiometrías. Para dicho fin se tomó la población de pilotos de fuerzas militares que fueron distribuidos en grupos de pilotos de aeronave de ala fija que corresponden a 47 pilotos y ala rotatoria que son 155. Conclusiones: Se encontró que la frecuencia mas alterada en la población total fue la de 6000 Hz, que en lo pilotos de ala fija las frecuencias más afectadas fueron las de 4000 Hz y la de 6000Hz, la frecuencia más afectada en los pilotos de ala rotatoria fueron las de 4000 Hz, 6000 Hz y 8000 Hz, con lo que se concluye que la exposición en los pilotos afecta las frecuencias altas en las audiometrías. Se observó una relación con el número de horas de vuelo y las alteraciones audiométricas encontrándose una alteración en los pilotos entre 1000 y 4000 horas de vuelo en las frecuencias de 4000 Hz, 6000 Hz y 8000 Hz y una alteración de las todas las frecuencias en aquellos pilotos con más de 5000 horas de vuelo en el año 2009, presentando posterior recuperación en los años posteriores sin poder determinar en este estudio las causas de dicha recuperación. Los pilotos de ala rotatoria presentaron un incremento sostenido en todas las frecuencias en comparación con los pilotos de ala fija.

El papel de las empresas de seguridad privada en la implementación de estrategias defensivas de seguridad militar en Irak (2004-2009)

La guerra de Irak del 2003 permitió la presencia y expansión de las Empresas de Seguridad Privada, tras demostrar su efectividad en el campo de batalla. Con el uso de estrategias y tácticas de guerra por parte de las ESP, que les otorgaron notables ventajas comparativas a los Estados frente a amenazas no convencionales que emergen de una guerra asimétrica, estas aumentaron su poder e influencia. Estos aportes en términos de la ejecución de la guerra contribuyeron a la construcción de la seguridad -militar-. Estados Unidos y Reino Unido actualmente son los principales consumidores y proveedores de este tipo de servicios, permitiéndole a las ESP un crecimiento más fuerte en sus capacidades y funciones.

Military empowerment and civilian targeting in civil war

Civilians constitute a large share of casualties in civil wars across the world. They are targeted to create fear and punish allegiance with the enemy. This maximizes collaboration with the perpetrator and strengthens the support network necessary to consolidate control over contested regions. I develop a model of the magnitude and structure of civilian killings in civil wars involving two armed groups who Öght over territorial control. Armies secure compliance through a combination of carrots and sticks. In turn, civilians di§er from each other in their intrinsic preference towards one group. I explore the e§ect of the empowerment of one of the groups in the civilian death toll. There are two e§ects that go in opposite directions. While a direct e§ect makes the powerful group more lethal, there is an indirect e§ect by which the number of civilians who align with that group increases, leaving less enemy supporters to kill. I study the conditions under which there is one dominant e§ect and illustrate the predictions using sub-national longitudinal data for Colombiaís civil war.

Age-specific survival of male Golden-cheeked Warblers on the Fort Hood Military Reservation, Texas

Population models are essential components of large-scale conservation and management plans for the federally endangered Golden-cheeked Warbler (Setophaga chrysoparia; hereafter GCWA). However, existing models are based on vital rate estimates calculated using relatively small data sets that are now more than a decade old. We estimated more current, precise adult and juvenile apparent survival (Φ) probabilities and their associated variances for male GCWAs. In addition to providing estimates for use in population modeling, we tested hypotheses about spatial and temporal variation in Φ. We assessed whether a linear trend in Φ or a change in the overall mean Φ corresponded to an observed increase in GCWA abundance during 1992-2000 and if Φ varied among study plots. To accomplish these objectives, we analyzed long-term GCWA capture-resight data from 1992 through 2011, collected across seven study plots on the Fort Hood Military Reservation using a Cormack-Jolly-Seber model structure within program MARK. We also estimated Φ process and sampling variances using a variance-components approach. Our results did not provide evidence of site-specific variation in adult Φ on the installation. Because of a lack of data, we could not assess whether juvenile Φ varied spatially. We did not detect a strong temporal association between GCWA abundance and Φ. Mean estimates of Φ for adult and juvenile male GCWAs for all years analyzed were 0.47 with a process variance of 0.0120 and a sampling variance of 0.0113 and 0.28 with a process variance of 0.0076 and a sampling variance of 0.0149, respectively. Although juvenile Φ did not differ greatly from previous estimates, our adult Φ estimate suggests previous GCWA population models were overly optimistic with respect to adult survival. These updated Φ probabilities and their associated variances will be incorporated into new population models to assist with GCWA conservation decision making.

Vegetation development and human occupation in the Damascus region of southwestern Syria from the Late Pleistocene to Holocene

Rockshelter Baaz in the Damascus region of Syria provided a variety of botanical remains from the Late Pleistocene and Early Holocene period. These remains provide new information about the vegetation evolution in this region. The earliest occupational levels correspond with a moisture peak during the Late Pleistocene, between ca. 34-32 kyr b.p., when pine expanded. The next occupations took place during extreme arid conditions, ca. 23-21 kyr b.p., and probably during the Last Glacial Maximum when a steppe vegetation was established. The occupation level of the Younger Dryas, represented by Natufian remains, suggests that the area had been covered by almond-pistachio steppe, similar to later periods of the Early Holocene, and was probably located just outside the range of dense wild cereal stands. There is no drastic impact of the Younger Dryas visible on the vegetation in the botanical remains. The lack of fruits and seeds at Baaz indicates that the site was more likely to have been a temporary hunting post rather than a plant processing site for much of its history. It is ideally suited to this purpose because of its location over the Jaba'deen Pass and the associated springs. However, archaeological remains from the Natufian period, suggest that the site was more permanently occupied during this time.

Archaeological evidence for the first Mesolithic occupation of the Western Isles of Scotland

The examination of eroding coastal dunes at the prehistoric site of Northton, Harris, has produced the first archaeological evidence of Mesolithic activity in the Western Isles in the form of two midden-related deposits. The first phase of Mesolithic activity is dated to 7060-6650 cal. Bc based on AMS dating of charred hazelnut shells. This discovery appears to validate the frequent pollen-based inferences of Mesolithic impact for the area and, as predicted, allows the Atlantic fringe of Scotland to become part of the European Mesolithic mainstream. A detailed pedological analysis also suggests that these early midden layers may have been amended during the Neolithic period as part of a possible phase of cultivation.
