    War, armies and soldiers were omnipresent in the ancient Greek society, and thus these phenomena are equally present in the worlds of ancient Greek comedy. However, the comic outlook on war differs from Old to New Comedy. While the citizen soldier remains the norm, but mainly at periphery of Old...... comedy, the independent mercenary becomes a central character of New Comedy. Thus the comic view on soldiers reflects the martial attitudes and ideologies of contemporary society....

    Counterinsurgency (COIN) has become the cornerstone of the military's strategy to combat terrorist threats. COIN operations are complex and often expose soldiers to unfamiliar stressors as they fight the enemy while developing and maintaining rapport with the local populace. Utilizing a retrospective record review protocol, we examined 282 mental health files of soldiers assigned to a brigade combat team that operated from a large forward operating base in Iraq during the counterinsurgency campaign. Most reported sleep disturbance, depression, anxiety, irritability, and conflict with supervisors related to either operational stress, exposure to direct combat, or home front concerns. Most received brief individual supportive therapy or attended solution-focused group counseling emphasizing life skills training, post-traumatic stress treatment, women's support, or relationship skills. Psychopharmacologic treatment was an essential adjunct to the counseling program. Results indicate that supporting a COIN deployment requires a comprehensive mental health program that can respond to a wide range of mental health problems.

    This study examined the moderating role of political ideology on psychological outcomes for Israeli soldiers participating in the forced evacuation of Jewish settlements from Gaza. Change in psychopathology and well-being was assessed for 3 concurrent mission groups differing in their political ideological contentiousness--forced evacuation, Gaza security, and Northern border security. After soldiers in each mission group were classified on the basis of relatively left- or right-wing political ideological tendencies, the authors examined differential impact of each mission on soldiers of differing political ideology. Results confirmed strong moderation effects of political ideology on psychological outcomes in these extreme contexts. Implications for research, prevention, and treatment are discussed. 2007 APA, all rights reserved

    Full Text Available In all countries around the world, the duties of the soldier are codified in detail, but in very different ways, according to the various histories, and cultural backgrounds of the respective Nations. As this soldier has the right to legally use a powerful lethal force, a lot is required from him, which is normal. He is now most often a professional. He has mainly to master perfectly his weapons, to respect the Law of Armed Conflicts and to apply the principle of humanity. But his leaders have to guide him and his Nation to understand and support him.

    available also can kill other aquatic life. Early implementation of containment and eradication efforts requires getting reliable information to confirm the location of the infestation. One way to get this information is through the use of properly trained SCUBA divers. This document provides SCUBA divers with the necessary information to conduct underwater searchers for mussels. However, using SCUBA divers to search for mussels over a large geographic area is relatively expensive and inefficient. Early detection monitoring methods can be used to optimize the use of SCUBA divers. Early detection monitoring can be accomplished by collecting water samples or deploying artificial settlement substrates (fig. 1). Water samples are used to look for free-swimming larval mussels (called veligers). Because the veligers cannot be identified with the naked eye, the water samples are sent to a laboratory where they are examined under a microscope and/or analyzed using molecular techniques to detect veligers. To detect the presences of adult mussels, artificial substrates are deployed and periodically retrieved to determine if mussels have settled on the substrate. If veligers or adults are identified, SCUBA divers can be deployed to confirm the presence of mussels.

  11. Literature search strategies for conducting knowledge-building and theory-generating qualitative systematic reviews.

    To report literature search strategies for the purpose of conducting knowledge-building and theory-generating qualitative systematic reviews. Qualitative systematic reviews lie on a continuum from knowledge-building and theory-generating to aggregating and summarizing. Different types of literature searches are needed to optimally support these dissimilar reviews. Articles published between 1989-Autumn 2011. These documents were identified using a hermeneutic approach and multiple literature search strategies. Redundancy is not the sole measure of validity when conducting knowledge-building and theory-generating systematic reviews. When conducting these types of reviews, literature searches should be consistent with the goal of fully explicating concepts and the interrelationships among them. To accomplish this objective, a 'berry picking' approach is recommended along with strategies for overcoming barriers to finding qualitative research reports. To enhance integrity of knowledge-building and theory-generating systematic reviews, reviewers are urged to make literature search processes as transparent as possible, despite their complexity. This includes fully explaining and rationalizing what databases were used and how they were searched. It also means describing how literature tracking was conducted and grey literature was searched. In the end, the decision to cease searching also needs to be fully explained and rationalized. Predetermined linear search strategies are unlikely to generate search results that are adequate for purposes of conducting knowledge-building and theory-generating qualitative systematic reviews. Instead, it is recommended that iterative search strategies take shape as reviews evolve. © 2012 Blackwell Publishing Ltd.

    In the rapidly developing specialty of palliative care, literature reviews have become increasingly important to inform and improve the field. When applying widely used methods for literature reviews developed for intervention studies onto palliative care, challenges are encountered such as the heterogeneity of palliative care in practice (wide range of domains in patient characteristics, stages of illness and stakeholders), the explorative character of review questions, and the poorly defined keywords and concepts. To overcome the challenges and to provide guidance for researchers to conduct a literature search for a review in palliative care, Palliative cAre Literature rEview iTeraTive mEthod (PALLETE), a pragmatic framework, was developed. We assessed PALETTE with a detailed description. PALETTE consists of four phases; developing the review question, building the search strategy, validating the search strategy and performing the search. The framework incorporates different information retrieval techniques: contacting experts, pearl growing, citation tracking and Boolean searching in a transparent way to maximize the retrieval of literature relevant to the topic of interest. The different components and techniques are repeated until no new articles are qualified for inclusion. The phases within PALETTE are interconnected by a recurrent process of validation on 'golden bullets' (articles that undoubtedly should be part of the review), citation tracking and concept terminology reflecting the review question. To give insight in the value of PALETTE, we compared PALETTE with the recommended search method for reviews of intervention studies. By using PALETTE on two palliative care literature reviews, we were able to improve our review questions and search strategies. Moreover, in comparison with the recommended search for intervention reviews, the number of articles needed to be screened was decreased whereas more relevant articles were retrieved. Overall, PALETTE

    2012-05-01

    To determine the prevalence and characteristics of, and factors associated with, chronic daily headache (CDH) in U.S. soldiers after a deployment-related concussion. A cross-sectional, questionnaire-based study was conducted with a cohort of 978 U.S. soldiers who screened positive for a deployment-related concussion upon returning from Iraq or Afghanistan. All soldiers underwent a clinical evaluation at the Madigan Traumatic Brain Injury Program that included a history, physical examination, 13-item self-administered headache questionnaire, and a battery of cognitive and psychological assessments. Soldiers with CDH, defined as headaches occurring on 15 or more days per month for the previous 3 months, were compared to soldiers with episodic headaches occurring less than 15 days per month. One hundred ninety-six of 978 soldiers (20%) with a history of deployment-related concussion met criteria for CDH and 761 (78%) had episodic headache. Soldiers with CDH had a median of 27 headache days per month, and 46/196 (23%) reported headaches occurring every day. One hundred seven out of 196 (55%) soldiers with CDH had onset of headaches within 1 week of head trauma and thereby met the time criterion for posttraumatic headache (PTHA) compared to 253/761 (33%) soldiers with episodic headache. Ninety-seven out of 196 (49%) soldiers with CDH used abortive medications to treat headache on 15 or more days per month for the previous 3 months. One hundred thirty out of 196 (66%) soldiers with CDH had headaches meeting criteria for migraine compared to 49% of soldiers with episodic headache. The number of concussions, blast exposures, and concussions with loss of consciousness was not significantly different between soldiers with and without CDH. Cognitive performance was also similar for soldiers with and without CDH. Soldiers with CDH had significantly higher average scores on the posttraumatic stress disorder (PTSD) checklist compared to soldiers with episodic headaches. Forty

    of the various international instruments containing proscriptive norms that aim to eradicate the use and recruitment of child soldiers. Chapter One illustrates that uncertainty exists regarding the use and recruitment of child soldiers – what should the parameters of such prohibition be? In Chapter Two the distribution, use and causes of child soldiering in armed conflict currently are discussed. Qua social reality, the distribution of child soldiers is of particular importance to the prevention of child soldiering, in the sense that reliance is placed on international machinery on a geo-specific basis. In similar vein the author illustrates that the capacity in which child soldiers are used also applies to the prevention of child soldiering, as different legal instruments prohibit only specific degrees of such participation in armed conflict. Of particular relevance is the argument conveyed by the author that the root causes for child soldiering must be understood because such understanding allows for the identification of strategies aimed at the prevention of child soldiering. Chapters Three and Four comprise a discussion of child soldiering in the context of International Humanitarian Law and International Human Rights Law. More particularly, an analysis of the relationship between these two disciplines is provided. This relation, the author emphatically argues, is of specific importance in the context of the prevention of child soldiering, as there is probably a larger degree of overlap between the prohibitive norms of the International Humanitarian Law and International Human Rights Law in this regard than in any other proscribed conduct. He points out in Chapter Four that substantive norms prohibiting child soldiering display certain weaknesses, but suggests that customary international law may present an avenue through which child soldier prevention can be further refined. Chapter Five is directed at the war crime of the use and recruitment of child soldiers

  4. Conducting systematic reviews of intervention questions I: Writing the review protocol, formulating the question and searching the literature.

    2014-06-01

    This article is the fourth of six articles addressing systematic reviews in animal agriculture and veterinary medicine. Previous articles in the series have introduced systematic reviews, discussed study designs and hierarchies of evidence, and provided details on conducting randomized controlled trials, a common design for use in systematic reviews. This article describes development of a review protocol and the first two steps in a systematic review: formulating a review question, and searching the literature for relevant research. The emphasis is on systematic reviews of questions related to interventions. The review protocol is developed prior to conducting the review and specifies the plan for the conduct of the review, identifies the roles and responsibilities of the review team and provides structured definitions related to the review question. For intervention questions, the review question should be defined by the PICO components: population, intervention, comparison and outcome(s). The literature search is designed to identify all potentially relevant original research that may address the question. Search terms related to some or all of the PICO components are entered into literature databases, and searches for unpublished literature also are conducted. All steps of the literature search are documented to provide transparent reporting of the process. © 2014 Blackwell Verlag GmbH.

    2011-04-01

    The objective of this study was to assess the risk factors for bladder cancer using PubMed articles from January 2000 to December 2009. The study also aimed to describe the challenges encountered in the methodology of a literature search for bladder cancer risk factors using PubMed. Twenty-six categories of risk factors for bladder cancer were identified using the National Cancer Institute Web site and the Medical Subject Headings (MeSH) Web site. A total of 1,338 PubMed searches were run using the term "urinary bladder cancer" and a risk factor term (e.g., "cigarette smoking") and were screened to identify 260 articles for final analysis. The search strategy had an overall precision of 3.42 percent, relative recall of 12.64 percent, and an F-measure of 5.39 percent. Although search terms derived from MeSH had the highest overall precision and recall, the differences did not reach significance, which indicates that for generalized, free-text searches of the PubMed database, the searchers' own terms are generally as effective as MeSH terms.

  8. Growing up in armed groups: trauma and aggression among child soldiers in DR Congo

    Directory of Open Access Journals (Sweden)

    Katharin Hermenau

    2013-11-01

    Full Text Available Background: Child soldiers are often both victims and perpetrators of horrendous acts of violence. Research with former child soldiers has consistently shown that exposure to violence is linked to trauma-related disorders and that living in a violent environment is correlated with enhanced levels of aggression. Objective: To gain more insight into the experiences and the mental health status of former child soldiers, we conducted a survey with N=200 former child soldiers and adult combatants in the DR Congo. Methods: We conducted semi-structured interviews concerning military experiences, experienced and perpetrated violence, and mental health. Results: Former child soldiers reported more experienced and perpetrated violence, a greater severity of trauma-related suffering, as well as higher appetitive aggression than adult ex-combatants. Appetitive aggression was related to more perpetrated violence, higher military ranks, voluntary recruitment and higher rates of reenlistments in former child soldiers. Conclusions: Our results indicate that growing up in an armed group is related to higher levels of trauma-related disorders and aggressive behavior. This may explain the challenge of reintegrating former child soldiers. It is thus important to consider mental health problems, particularly trauma-related disorders and aggressive behavior, of former child soldiers for designing adequate reintegration programs.

    Johannessen, Steinar; Holgersen, Helge

    2014-01-01

    With this article, we explore how staff working at transit centers and vocational training centers in the eastern Democratic Republic of the Congo experienced the problems and needs of former child soldiers. We argued that the staff's experience of the children's daily lives and their understanding of the sociocultural context of the conflict make their perspective a valuable source of information when trying to understand the phenomenon of child soldiering. Additionally, we reasoned that how the staff frame these children's problems influences how they attempt to aid the children. We conducted 11 semistructured interviews and analyzed these using a hermeneutical-phenomenological approach. We clustered our findings around six themes: unfavorable contextual factors, acting as if still in the army, addiction, symptoms of psychopathology, social rejection, and reintegration needs. The overarching message we observed was that the informants experienced that former child soldiers require help to be transformed into civilians who participate proactively in their society.

  11. Soldiers' Preferences Regarding Sperm Preservation, Posthumous Reproduction, and Attributes of a Potential "Posthumous Mother".

    Science.gov (United States)

    Bokek-Cohen, Ya'arit; Ravitsky, Vardit

    2017-01-01

    We present study results regarding soldiers' willingness to conduct posthumous reproduction. Two hundred twelve Israeli soldiers filled in a questionnaire designed to examine their willingness to cryopreserve sperm and evaluate in which familial circumstances they would consent to posthumous reproduction. They ranked the desirability of 46 attributes of a potential mother and a life partner. Findings indicate a relatively high predisposition in favor of posthumous-assisted reproduction; the wishes of soldiers' parents had much more influence on soldiers' willingness to pursue this technology than those of a partner. Soldiers preferred "feminine" jobs for a potential mother that would allow her to dedicate herself to child-rearing. The desired traits of such a mother were rated similarly to partner preferences; however, significant differences were found in attributes that are most related to the potential mother's devotion to maternity. Interpretations of these findings are contextualized in relation to ethical and bereavement considerations.

  12. Exploring L1 model space in search of conductivity bounds for the MT problem

    Science.gov (United States)

    Wheelock, B. D.; Parker, R. L.

    2013-12-01

    Geophysical inverse problems of the type encountered in electromagnetic techniques are highly non-unique. As a result, any single inverted model, though feasible, is at best inconclusive and at worst misleading. In this paper, we use modified inversion methods to establish bounds on electrical conductivity within a model of the earth. Our method consists of two steps, each making use of the 1-norm in model regularization. Both 1-norm minimization problems are framed without approximation as non-negative least-squares (NNLS) problems. First, we must identify a parsimonious set of regions within the model for which upper and lower bounds on average conductivity will be sought. This is accomplished by minimizing the 1-norm of spatial variation, which produces a model with a limited number of homogeneous regions; in fact, the number of homogeneous regions will never be greater than the number of data, regardless of the number of free parameters supplied. The second step establishes bounds for each of these regions with pairs of inversions. The new suite of inversions also uses a 1-norm penalty, but applied to the conductivity values themselves, rather than the spatial variation thereof. In the bounding step we use the 1-norm of our model parameters because it is proportional to average conductivity. For a lower bound on average conductivity, the 1-norm within a bounding region is minimized. For an upper bound on average conductivity, the 1-norm everywhere outside a bounding region is minimized. The latter minimization has the effect of concentrating conductance into the bounding region. Taken together, these bounds are a measure of the uncertainty in the associated region of our model. Starting with a blocky inverse solution is key in the selection of the bounding regions. Of course, there is a tradeoff between resolution and uncertainty: an increase in resolution (smaller bounding regions), results in greater uncertainty (wider bounds). Minimization of the 1-norm of

    We described the risk for maltreatment among toddlers of US Army soldiers over different deployment cycles to develop a systematic response within the US Army to provide families appropriate supports. We conducted a person-time analysis of substantiated maltreatment reports and medical diagnoses among children of 112,325 deployed US Army soldiers between 2001 and 2007. Risk of maltreatment was elevated after deployment for children of soldiers deployed once but not for children of soldiers deployed twice. During the 6 months after deployment, children of soldiers deployed once had 4.43 substantiated maltreatment reports and 4.96 medical diagnoses per 10,000 child-months. The highest maltreatment rate among children of soldiers deployed twice occurred during the second deployment for substantiated maltreatment (4.83 episodes per 10,000 child-months) and before the first deployment for medical diagnoses of maltreatment (3.78 episodes per 10,000 child-months). We confirmed an elevated risk for child maltreatment during deployment but also found a previously unidentified high-risk period during the 6 months following deployment, indicating elevated stress within families of deployed and returning soldiers. These findings can inform efforts by the military to initiate and standardize support and preparation to families during periods of elevated risk.

    Recent research in military sociology has shown that in addition to their strong peer motivation modern soldiers are oriented toward contributing to society. It has not, however, been tested how soldier motivation differs from the motivation of other citizens in this respect. In this paper......, by means of public service motivation, a concept developed within the public administration literature, we compare soldier and civilian motivation. The contribution of this paper is an analysis of whether and how Danish combat soldiers differs from other Danes in regard to public service motivation? Using...... surveys with similar questions, we find that soldiers are more normatively motivated to contribute to society than other citizens (higher commitment to the public interest), while their affectively based motivation is lower (lower compassion).

    2011-01-01

    Carefully implemented technology strategies are vital to the success of large-scale initiatives such as the U.S. Army's Comprehensive Soldier Fitness (CSF) program. Achieving the U.S. Army's vision for CSF required a robust information technology platform that was scaled to millions of users and that leveraged the Internet to enable global reach. The platform needed to be agile, provide powerful real-time reporting, and have the capacity to quickly transform to meet emerging requirements. Existing organizational applications, such as "Single Sign-On," and authoritative data sources were exploited to the maximum extent possible. Development of the "Soldier Fitness Tracker" is the most recent, and possibly the best, demonstration of the potential benefits possible when existing organizational capabilities are married to new, innovative applications. Combining the capabilities of the extant applications with the newly developed applications expedited development, eliminated redundant data collection, resulted in the exceeding of program objectives, and produced a comfortable experience for the end user, all in less than six months. This is a model for future technology integration. (c) 2010 APA, all rights reserved.

    Women are an integral part of Reserve and National Guard units and active duty armed forces of the United States. Deployment to conflict and war zones is a difficult experience for both soldiers and their families. On return from deployment, all soldiers face the challenge of reintegration into family life and society, but those from the National Guard and Reserve units face the additional challenge of reintegration in relative isolation from other soldiers. There is limited research about the reintegration experiences of women and the functioning of the families during reintegration following deployment. The goal was to document postdeployment family reintegration experiences of women in the National Guard. Semistructured interviews were conducted with 42 female members of Midwestern National Guard units. Directed content analysis was used to identify categories of experiences related to women's family reintegration. Five categories of postdeployment experience for female soldiers and their families were identified: Life Is More Complex, Loss of Military Role, Deployment Changes You, Reestablishing Partner Connections, and Being Mom Again. The categories reflected individual and family issues, and both need to be considered when soldiers and their families seek care. Additional research is needed to fully understand the specific impact of gender on women's reintegration.

    2017-11-14

    The availability of adequate water to meet the present (2017) and future needs of humans, fish, and wildlife is a fundamental issue for the Prairie Band Potawatomi Nation in northeast Kansas. Because Soldier Creek flows through the Prairie Band Potawatomi Nation Reservation, it is an important tribal resource. An understanding of historical Soldier Creek streamflow conditions is required for the effective management of tribal water resources, including drought contingency planning. Historical data for six selected U.S. Geological Survey (USGS) streamgages along Soldier Creek were used in an assessment of streamflow characteristics and trends by Juracek (2017). Streamflow data for the period of record at each streamgage were used to compute annual mean streamflow, annual mean base flow, mean monthly flow, annual peak flow, and annual minimum flow. Results of the assessment are summarized in this fact sheet.

    2013-01-01

    To determine the impact of post-traumatic stress disorder (PTSD) on headache characteristics and headache prognosis in U.S. soldiers with post-traumatic headache. PTSD and post-concussive headache are common conditions among U.S. Army personnel returning from deployment. The impact of comorbid PTSD on the characteristics and outcomes of post-traumatic headache has not been determined in U.S. Army soldiers. A retrospective cohort study was conducted among 270 consecutive U.S. Army soldiers diagnosed with post-traumatic headache at a single Army neurology clinic. All subjects were screened for PTSD at baseline using the PTSD symptom checklist. Headache frequency and characteristics were determined for post-traumatic headache subjects with and without PTSD at baseline. Headache measures were reassessed 3 months after the baseline visit, and were compared between groups with and without PTSD. Of 270 soldiers with post-traumatic headache, 105 (39%) met screening criteria for PTSD. There was no significant difference between subjects with PTSD and those without PTSD with regard to headache frequency (17.2 vs 15.7 headache days per month; P = .15) or chronic daily headache (58.1% vs 52.1%; P = .34). Comorbid PTSD was associated with higher headache-related disability as measured by the Migraine Disability Assessment Score. Three months after the baseline neurology clinic visit, the number of subjects with at least 50% reduction in headache frequency was similar among post-traumatic headache cases with and without PTSD (25.9% vs 26.8%). PTSD is prevalent among U.S. Army soldiers with post-traumatic headache. Comorbid PTSD is not associated with more frequent headaches or chronic daily headache in soldiers evaluated at a military neurology clinic for chronic post-traumatic headache. Comorbid PTSD does not adversely affect short-term headache outcomes, although prospective controlled trials are needed to better assess this relationship. © 2013 American Headache

    Objective: To investigate the occupational predispositions of low back pain in soldiers Study Design: Descriptive study. Place and Duration of Study: Combined Military Hospital, Bahawalpur, from June 2009 to Jan 2010. Patients and Methods: A questionnaire was developed to investigate the occupation-related issues in soldiers reporting with low backache in surgical OPD at CMH Bahawalpur. It included personal and occupational factors. The body mass index was also calculated. Of the 107 male soldiers assessed, 90 were enrolled into the study. The statistical analysis was performed by descriptive analysis of the data using SPSS 17.0. Results: Of all the soldiers evaluated (n=90), 32 (35.6%) were clerks/computer operators, 21 (23.1%) were drivers and 14(15.6%) were signal men. All were males (100%) and the average BMI was 24.8 kg/m2. The 69 (76.7%) patients who had backache had prolonged working hours (average 10.8 hours per day), 68 (75.6%) patients used to sleep over tape/nawar bed and only 12 (13.3%) had been sleeping on mattresses. The onset of pain was sudden in 58 (64.4%) patients. 27 (23.3%) had developed acute backache after prolonged sitting, 21 (30%) after lifting heavy objects. The pain was exaggerated by doing morning physical training 82 (91.1%), prolonged sitting 61 (67.8%) and standing with rifle 24 (26.7%). Conclusion: The prevalence of low back pain in sedentary occupation or soldiers on sitting jobs was higher 69 (76%). The number of working hours on these occupations was associated with occurrence as well as aggravation of low back pain. (author)

  18. Searching for Natural Conductive Fibrous Structures via a Green Sustainable Approach Based on Jute Fibers and Silver Nanoparticles

    Diana P. Ferreira

    2018-01-01

    Full Text Available This paper provides new insights regarding jute fibers functionalization with silver nanoparticles (Ag NPs with improved conductivity values and highlights the sustainability of the processes involved. These NPs were applied onto jute fabrics by two different sustainable methods: ultraviolet (UV photoreduction and by using polyethylene glycol (PEG as a reducing agent and stabilizer. Field Emission Scanning Electron Microscopy (FESEM images demonstrated that the Ag NPs were incorporated on the jute fibers surface by the two different approaches, with sizes ranging from 70 to 100 nm. Diffuse reflectance spectra revealed the plasmon absorption band, corresponding to the formation of metallic Ag NPs, in all samples under study. Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR was used to characterize the obtained samples, demonstrating NPs adsorption to the surface of the fibers. The resistivity value obtained by the two-point probe method of the jute fabric without functionalization is about 1.5 × 107 Ω·m, whereas, after NPs functionalization, it decreased almost 15,000 times, reaching a value of 1.0 × 103 Ω·m. Further research work is being undertaken for improving these values, however, 1000 Ω·m of resistivity (conductivity = 0.001 S/m is already a very reasonable value when compared with those obtained with other developed systems based on natural fibers. In summary, this work shows that the use of very simple methodologies enabled the functionalization of jute fibers with reasonable values of conductivity. This achievement has a huge potential for use in smart textile composites.

    Cognitive Resource Theory (CRT) suggests that under high levels of stress, employees are more prone to committing indiscipline. As few studies have examined this relationship over time, the authors conducted a six-wave longitudinal study examining the relationship of soldiers' indiscipline with work demands and control. The study included archival data collected quarterly over 2 years from 1,701 soldiers representing 10 units in garrison (Germany and Italy), in training rotations (Grafenwoehr, Germany), and on peacekeeping deployments (Kosovo, Kuwait). No main effects were found for work overload, and the findings for the moderating effects of control were contradictory. Within each time point, as work overload increased, soldiers who felt less control committed more indiscipline, supporting CRT. Over time, however, as work overload increased, soldiers who perceived less control 6 months earlier committed less indiscipline. Additionally, the authors found reverse causal effects for control such that prior perceptions of a lack of control were associated with indiscipline and prior incidents of indiscipline with less control.

    In order to best tailor suicide prevention initiatives and programs, it is critical to gain an understanding of how service members׳ suicide risk factors may differ by gender. We aimed to better understand gender differences in suicide and suicide attempts among soldiers, including demographic, military, mental health, and other risk factors. We also examined risk factors uniquely associated with suicide and suicide attempts. We conducted a retrospective study of 1857 US Army soldiers who died by suicide or attempted suicide between 2008 and 2010 and had a Department of Defense Suicide Event Report. Female and male soldiers had more similarities than differences when examining risk factors associated with suicide. The only gender difference approaching significance was workplace difficulties, which was more strongly associated with suicide for female soldiers, compared to their male counterparts. Among suicide decedents, the most common risk factor was having a failed intimate relationship in the 90 days prior to suicide. Among those who attempted suicide, the most common risk factor was a major psychiatric diagnosis. Better understanding both gender differences and risk factors uniquely associated with suicide has critical prevention and public health implications as we work to better understand preventable mortality in our youngest generation of service members.

    Adverse social conditions in early life have been linked to increased expression of proinflammatory genes and reduced expression of antiviral genes in circulating immune cells-the conserved transcriptional response to adversity (CTRA). However, it remains unclear whether such effects are specific to the Western, educated, industrialized, rich, and democratic (WEIRD) cultural environments in which previous research has been conducted. To assess the roles of early adversity and individual psychological resilience in immune system gene regulation within a non-WEIRD population, we evaluated CTRA gene-expression profiles in 254 former child soldiers and matched noncombatant civilians 5 y after the People's War in Nepal. CTRA gene expression was up-regulated in former child soldiers. These effects were linked to the degree of experienced trauma and associated distress-that is, posttraumatic stress disorder (PTSD) severity-more than to child soldier status per se. Self-perceived psychological resilience was associated with marked buffering of CTRA activation such that PTSD-affected former child soldiers with high levels of personal resilience showed molecular profiles comparable to those of PTSD-free civilians. These results suggest that CTRA responses to early life adversity are not restricted to WEIRD cultural contexts and they underscore the key role of resilience in determining the molecular impact of adverse environments.

    Full Text Available Background: Constant checkup and control of body fat mass is an important parameter for the health and efficiency of individuals in any society. This parameter is especially crucial in army soldiers since physical fitness is a key role in reaching high physical performance, health, and survival in war. Objective: This study was designed to compare two methods of measuring fat, the method of circumference-based military equations (CBEs to estimate body fat mass compared to the method of skinfold thickness-based equation (SBE in Iranian soldiers. Methods: This cross-sectional study was conducted on 246 Iranian soldiers were recruited in Tehran (2016. Height, waist, and neck circumference were measured and the total body fat mass was calculated using CBEs. Then, the results of using Pierson’s correlation and Bland-Altman methods were compared with Jackson and Pollock’s skinfold thickness measurement. Findings: The total body fat mass of the soldiers using CBEs was 18.94±6.30% and using Jakson and Pollock’s skinfold thickness formula was 17.43±4.45%. The correlation between the two methods was r=0.984 and SEE was 1.1% (P<0.001. Conclusion: The more body fat makes the error waist circumference greater. The error is so much that don’t use this method to measure fat.

    In this prospective study, subjective sleep quality and excessive daytime sleepiness prior to, during and after deployment of German soldiers in Afghanistan were examined. Sleep quality (Pittsburgh Sleep Quality Index; PSQI) and daytime sleepiness (Epworth Sleepiness Scale; ESS) were assessed in 118 soldiers of the German army, who were deployed in Afghanistan for 6 months (deployment group: DG) and in 146 soldiers of a non-deployed control group (CG) at baseline. Results of the longitudinal analysis are reported, based on assessments conducted prior to, during the deployment and afterwards in the DG, and in the CG in parallel. Sleep quality and daytime sleepiness in the DG were already impaired during the predeployment training phase and remained at that level during the deployment phase, which clearly indicates the need for more attention on sleep in young soldiers, already at this early stage. The percentage of impaired sleepers decreased significantly after deployment. Programmes to teach techniques to improve sleep and reduce stress should be implemented prior to deployment to reduce sleep difficulties and excessive daytime sleepiness and subsequent psychiatric disorders. © 2017 European Sleep Research Society.

  4. EVALUATING THE SENSITIVITY OF RADIONUCLIDE DETECTORS FOR CONDUCTING A MARITIME ON-BOARD SEARCH USING MONTE CARLO SIMULATION IMPLEMENTED IN AVERT(regsign)

    Harris, S.; Dave Dunn, D.

    2009-01-01

    The sensitivity of two specific types of radionuclide detectors for conducting an on-board search in the maritime environment was evaluated using Monte Carlo simulation implemented in AVERT(reg s ign). AVERT(reg s ign), short for the Automated Vulnerability Evaluation for Risk of Terrorism, is personal computer based vulnerability assessment software developed by the ARES Corporation. The sensitivity of two specific types of radionuclide detectors for conducting an on-board search in the maritime environment was evaluated using Monte Carlo simulation. The detectors, a RadPack and also a Personal Radiation Detector (PRD), were chosen from the class of Human Portable Radiation Detection Systems (HPRDS). Human Portable Radiation Detection Systems (HPRDS) serve multiple purposes. In the maritime environment, there is a need to detect, localize, characterize, and identify radiological/nuclear (RN) material or weapons. The RadPack is a commercially available broad-area search device used for gamma and also for neutron detection. The PRD is chiefly used as a personal radiation protection device. It is also used to detect contraband radionuclides and to localize radionuclide sources. Neither device has the capacity to characterize or identify radionuclides. The principal aim of this study was to investigate the sensitivity of both the RadPack and the PRD while being used under controlled conditions in a simulated maritime environment for detecting hidden RN contraband. The detection distance varies by the source strength and the shielding present. The characterization parameters of the source are not indicated in this report so the results summarized are relative. The Monte Carlo simulation results indicate the probability of detection of the RN source at certain distances from the detector which is a function of transverse speed and instrument sensitivity for the specified RN source

    2000-09-22

    The aphid Pseudoregma sundanica (Van der Goot) (Homoptera: Aphididae) has two defence strategies. It is obligatorily tended by various species of ant and also produces sterile soldiers. We investigated how they allocate their investment in these two strategies. We measured the size, number of soldiers, number and species of tending ant, and number and species of predators in P. sundanica populations. We found that the level of ant tending correlated negatively with soldier investment in P. sundanica. The species of tending ant also influenced soldier investment. We excluded ants from aphid populations and recorded changes in population size and structure over four weeks. Ant exclusion led to population decline and extinction. At the same time, surviving populations showed a significant increase in soldier investment. The data demonstrate that social aphids can adjust their investment in soldiers in direct response to environmental change.

    US Army soldiers diagnosed with type 1 diabetes were previously considered unfit for duty. For highly motivated soldiers, current advanced technologies allow the possibility of not only retention on active duty, but military deployment. We present our experience at Fort Bragg, North Carolina, taking care of soldiers newly diagnosed with type 1 diabetes mellitus. Through intensive diabetes education, extensive military and physical training, optimization of diabetes technology, and remote real-time monitoring, soldiers are able to continue to serve their country in the most specialized roles.

  7. Tyraminergic and Octopaminergic Modulation of Defensive Behavior in Termite Soldier.

    Directory of Open Access Journals (Sweden)

    Yuki Ishikawa

    Full Text Available In termites, i.e. a major group of eusocial insects, the soldier caste exhibits specific morphological characteristics and extremely high aggression against predators. Although the genomic background is identical to the other non-aggressive castes, they acquire the soldier-specific behavioral character during the course of caste differentiation. The high aggressiveness and defensive behavior is essential for colony survival, but the neurophysiological bases are completely unknown. In the present study, using the damp-wood termite Hodotermopsis sjostedti, we focused on two biogenic amines, octopamine (OA and tyramine (TA, as candidate neuromodulators for the defensive behavior in soldiers. High-performance liquid chromatographic analysis revealed that TA levels in the brain and suboesophageal ganglion (SOG and the OA level in brain were increased in soldiers than in pseudergates (worker caste. Immunohistochemical analysis revealed that TA/OA neurons that innervate specific areas, including the mandibular muscles, antennal nerve, central complex, suboesophageal ganglion, and thoracic and/or abdominal ganglia, were enlarged in a soldier-specific manner. Together with the results that pharmacological application of TA promoted the defensive behavior in pseudergates, these findings suggest that the increased TA/OA levels induce the higher aggressiveness and defensive behavior in termite soldiers. The projection targets of these soldier-specific enlarged TA/OA neurons may have important roles in the higher aggressiveness and defensive behavior of the termite soldiers, inducing the neuronal transition that accompanies external morphological changes.

    Identification of new biomarkers of food and nutrient intake has developed fast over the past two decades and could potentially provide important new tools for compliance monitoring and dietary intake assessment in nutrition and health science. In recent years, metabolomics has played an important role in identifying a large number of putative biomarkers of food intake (BFIs). However, the large body of scientific literature on potential BFIs outside the metabolomics area should also be taken into account. In particular, we believe that extensive literature reviews should be conducted and that the quality of all suggested biomarkers should be systematically evaluated. In order to cover the literature on BFIs in the most appropriate and consistent manner, there is a need for appropriate guidelines on this topic. These guidelines should build upon guidelines in related areas of science while targeting the special needs of biomarker methodology. This document provides a guideline for conducting an extensive literature search on BFIs, which will provide the basis to systematically validate BFIs. This procedure will help to prioritize future work on the identification of new potential biomarkers and on validating these as well as other biomarker candidates, thereby providing better tools for future studies in nutrition and health.

    Full Text Available Abstract Identification of new biomarkers of food and nutrient intake has developed fast over the past two decades and could potentially provide important new tools for compliance monitoring and dietary intake assessment in nutrition and health science. In recent years, metabolomics has played an important role in identifying a large number of putative biomarkers of food intake (BFIs. However, the large body of scientific literature on potential BFIs outside the metabolomics area should also be taken into account. In particular, we believe that extensive literature reviews should be conducted and that the quality of all suggested biomarkers should be systematically evaluated.

    Full Text Available Current armed conflicts are asymmetrical and are developed m urban areas. These new requirements have not been studied for current literature. The aim of this study was to analyse changes in cortical arousal, blood lactate, muscle strength, autonomic modulation and rate of perceived exertion in a simulated urban combat. We analyzed 20 soldiers before and after an urban combat simulation. The results showed how urban combat produced high sympathetic nervous system activation, increasing the muscle strength, heart rate and blood lactate concentration of the soldiers. Despite this effort, rate of perceived exertion were not consistent with the physiological response that soldiers presented, the rate of perceived exertion was lower than the physiological response evaluated. Furthermore, the information processing and cortical arousal decreased after the urban combat simulation. These results have showed the psycho-physiological response of soldiers in combat, helping to better understanding and enabling an improvement of current training methods of soldiers.

    Viral hepatitis rates among U.S. Army soldiers in Europe have been found to be two to three times higher than corresponding rates for soldiers stationed in the U.S. Sera from 89 per cent of a representative Army unit with 865 members and a known hepatitis problem were tested for HBsAg, anti-HBs, anti-HBc, and anti-HA. The prevalence of HB markers was 20 per cent, and hepatitis A antibody was present in 25 per cent. A six-month follow-up, conducted on 260 individuals initially negative for all four tests, revealed that 11 of these were now HB seropositive, whereas none had seroconverted to anti-HA positive. The HB virus was the principal agent responsible for hepatitis in the unit surveyed. PMID:228562

    Full Text Available This study aimed to evaluate the potential contribution of informal community initiatives and formal interventions in support of former child soldiers' resilience in the wake of armed conflict. Using a cross-sectional survey design, a stratified random sample of 330 formerly recruited and 677 nonrecruited young people was consulted about their perspective on desirable support for former child soldiers provided by close support figures, communities, humanitarian organizations, and governments. Data analysis occurred by conducting qualitative thematic analysis and statistical chi-square analysis to explore clusters, similarities, and variations in reported support across the different “agents,” hereby comparing the perspectives of formerly recruited and non-recruited participants. The results indicated that formerly recruited and non-recruited participants had comparable perspectives that call for the contribution of various informal and formal support systems to former child soldiers' human capacities and the communal sociocultural fabric of war-affected societies. This highlights the importance of community-based, collective, and comprehensive support of formerly recruited young people and their surroundings in the aftermath of armed conflict.

    Cognitive skills training has been linked to greater skills, self-efficacy, and performance. Although research in a variety of organizational settings has demonstrated training efficacy, few studies have assessed cognitive skills training using rigorous, longitudinal, randomized trials with active controls. The present study examined cognitive skills training in a high-risk occupation by randomizing 48 platoons (N = 2,432 soldiers) in basic combat training to either (a) mental skills training or (b) an active comparison condition (military history). Surveys were conducted at baseline and 3 times across the 10-week course. Multilevel mixed-effects models revealed that soldiers in the mental skills training condition reported greater use of a range of cognitive skills and increased confidence relative to those in the control condition. Soldiers in the mental skills training condition also performed better on obstacle course events, rappelling, physical fitness, and initial weapons qualification scores, although effects were generally moderated by gender and previous experience. Overall, effects were small; however, given the rigor of the design, the findings clearly contribute to the broader literature by providing supporting evidence that cognitive training skills can enhance performance in occupational and sports settings. Future research should address gender and experience to determine the need for targeting such training appropriately. (c) 2015 APA, all rights reserved).

    Child Soldiers as Refugees in Germany How do former child soldiers cope with their potentially traumatic experiences, and how do the living conditions as refugees influence these coping processes? A dissertation at the faculty of human and social sciences at the University of Wuppertal, based on biographical-narrative interviews with 15 young refugees from six African countries, describes the characteristics of the traumatic sequences in the countries of origin and in exile, and elaborates typical coping processes. In order to survive a situation of absolute subjection within armed groups, children develop forms of adequate adaptation to the context like regulation and detachment of emotions e.g. with the use of drugs, assimilation to an idea of "hard masculinity" etc. They become victims, witnesses and often perpetrators of extreme violence (man-made-disaster), respectively traumatic processes can be seen in all sequences. After leaving the armed groups there is no way back into the families and communities destroyed by armed conflict, so they become refugees. In Germany, they are subjected to a bureaucratic and excluding asylum system, in which decisions on all relevant areas of life (age determination, place and right of residence, form of accommodation, access to education, etc.) are imposed on them. Especially the insecure right of residence and the living conditions in refugee camps are severe risk factors, impeding stabilization. Social support, e. g. by competent professionals, access to trauma- and culture-sensitive psychotherapy, societal inclusion, but also personal resilience are essential for coping with trauma and developing new future perspectives.

    In Medieval Europe, soldiers wore steel plate armour for protection during warfare. Armour design reflected a trade-off between protection and mobility it offered the wearer. By the fifteenth century, a typical suit of field armour weighed between 30 and 50 kg and was distributed over the entire body. How much wearing armour affected Medieval soldiers' locomotor energetics and biomechanics is unknown. We investigated the mechanics and the energetic cost of locomotion in armour, and determined...

    Full Text Available Background/Aim. Analyses of suicide risk factors enable to undertake appropriate preventive measures within the Suicide Prevention Program in Military Environment, which was fully applied in 2003 in the Serbian Army Forces. The aim of our study was to identify the most important suicide risk factors in soldiers within the period from 1998 to 2007. Methods. Analysis of suicide risk factors was carried out on the basis of data obtained by psychological suicide autopsy. The control group was matched with adapted soldiers by socio-demographic factors. A descriptive statistical analysis was used. Comparison of groups of soldiers was done by the t-test and Pearson's χ2-test. Results. A total of 35 soldiers aged 22-49 years (21.76 ± 1.76 years on average committed suicide within the period 1999-2007, the 2/3 within, and 1/3 out of a military compound. More than one half soldiers committed suicide after transferring to a different post. Soldiers who committed suicide had come from uncompleted, dysfunctional families (p < 0.05. In comparison with the adapted soldiers, in premilitary period they had more interpersonal problems with their comrades (p < 0.001 and problems with law (p < 0.05. During military service, alcohol consumption was less presented; they used to have fewer separation problems (p < 0.05 and to be rarely awarded (p < 0.001 in comparison with the adapted soldiers. A soldier who committed suicide was emotionally and socially immature persons. The commonest motives for suicide were: decreased capacity of adaptation to military service, actual psychic disturbance, emotional interruption, fear of environment judgment, actual family problems, but in the one fifth, motive stayed unrecognized. Conclusion. Suicide risk factors in soldiers are primary in their immature personality organization, its relation with family and military environment factors which, in coexistence with actual life accidents, result in suicide as a consequence.

  15. Exoskeleton for Soldier Enhancement Systems Feasibility Study

    Energy Technology Data Exchange (ETDEWEB)

    Jansen, J.F.

    2000-09-28

    The development of a successful exoskeleton for human performance augmentation (EHPA) will require a multi-disciplinary systems approach based upon sound biomechanics, power generation and actuation systems, controls technology, and operator interfaces. The ability to integrate key components into a system that enhances performance without impeding operator mobility is essential. The purpose of this study and report are to address the issue of feasibility of building a fieldable EHPA. Previous efforts, while demonstrating progress and enhancing knowledge, have not approached the level required for a fully functional, fieldable system. It is doubtless that the technologies required for a successful exoskeleton have advanced, and some of them significantly. The question to be addressed in this report is have they advanced to the point of making a system feasible in the next three to five years? In this study, the key technologies required to successfully build an exoskeleton have been examined. The primary focus has been on the key technologies of power sources, actuators, and controls. Power sources, including internal combustion engines, fuel cells, batteries, super capacitors, and hybrid sources have been investigated and compared with respect to the exoskeleton application. Both conventional and non-conventional actuator technologies that could impact EHPA have been assessed. In addition to the current state of the art of actuators, the potential for near-term improvements using non-conventional actuators has also been addressed. Controls strategies, and their implication to the design approach, and the exoskeleton to soldier interface have also been investigated. In addition to these key subsystems and technologies, this report addresses technical concepts and issues relating to an integrated design. A recommended approach, based on the results of the study is also presented.

    2015-05-01

    The ability to accurately and rapidly know the precise location of enemy fire would be a substantial capability enhancement to the dismounted soldier. Acoustic gun-shot detections systems can provide an approximate bearing but it is desired to precisely know the location (direction and range) of enemy fire; for example to know from `which window' the fire is coming from. Funded by the UK MOD (via Roke Manor Research) QinetiQ is developing an imaging solution built around an InGaAs camera. This paper presents work that QinetiQ has undertaken on the Muzzle Flash Locator system. Key technical challenges that have been overcome are explained and discussed in this paper. They include; the design of the optical sensor and processing hardware to meet low size, weight and power requirements; the algorithm approach required to maintain sensitivity whilst rejecting false alarms from sources such as close passing insects and sun glint from scene objects; and operation on the move. This work shows that such a sensor can provide sufficient sensitivity to detect muzzle flash events to militarily significant ranges and that such a system can be combined with an acoustic gunshot detection system to minimize the false alarm rate. The muzzle flash sensor developed in this work operates in real-time and has a field of view of approximately 29° (horizontal) by 12° (vertical) with a pixel resolution of 0.13°. The work has demonstrated that extension to a sensor with realistic angular rotation rate is feasible.

    To ensure vision readiness on the battlefield, the French military has been providing its soldiers with eyewear since World War I. A military refractive surgery program was initiated in 2008. A prospective questionnaire-based investigation on optical correction and quality of vision among active duty members with visual deficiencies stationed in Djibouti, Africa, was conducted in 2009. It revealed that 59.3% of the soldiers were wearing spectacles, 21.2% were wearing contact lenses--despite official recommendations--and 8.5% had undergone refractive surgery. Satisfaction rates were high with refractive surgery and contact lenses; 33.6% of eyeglass wearers were planning to have surgery. Eye dryness and night vision disturbances were the most reported symptoms following surgery. Military optical devices were under-prescribed before deployment. This suggests that additional and more effective studies on the use of military optical devices should be performed and policy supporting refractive surgery in military populations should be strengthened.

    Background Studies have suggested that sickle cell trait elevates the risks of exertional rhabdomyolysis and death. We conducted a study of sickle cell trait in relation to these outcomes, controlling for known risk factors for exertional rhabdomyolysis, in a large population of active persons who had undergone laboratory tests for hemoglobin AS (HbAS) and who were subject to exertional-injury precautions. Methods We used Cox proportional-hazards models to test whether the risks of exertional rhabdomyolysis and death varied according to sickle cell trait status among 47,944 black soldiers who had undergone testing for HbAS and who were on active duty in the U.S. Army between January 2011 and December 2014. We used the Stanford Military Data Repository, which contains comprehensive medical and administrative data on all active-duty soldiers. Results There was no significant difference in the risk of death among soldiers with sickle cell trait, as compared with those without the trait (hazard ratio, 0.99; 95% confidence interval [CI], 0.46 to 2.13; P = 0.97), but the trait was associated with a significantly higher adjusted risk of exertional rhabdomyolysis (hazard ratio, 1.54; 95% CI, 1.12 to 2.12; P = 0.008). This effect was similar in magnitude to that associated with tobacco use, as compared with no use (hazard ratio, 1.54; 95% CI, 1.23 to 1.94; Prhabdomyolysis.

    Members of the Polish Military Contingent (PMC) have been stationed in Afghanistan since 2002. They typically serve in areas characterised by low standards of sanitation which often leads to the development of food- and waterborne diseases. The aim of the study was to evaluate the prevalence of Giardia intestinalis infections among Polish soldiers deployed to Afghanistan. The research study was conducted as part of a programme for prevention of parasitic diseases of the gastrointestinal tract run by the Polish Armed Forces. The study was carried out in August 2011; it involved 630 asymptomatic Polish soldiers serving in the Forward Operational Base (FOB) Ghazni in eastern Afghanistan. Stool specimens obtained from members of the PMC were first tested in FOB Ghazni (detection of Giardia intestinalis by Rida Quick Giardia immunochromatographic tests and Ridascreen Giardia immunoenzymatic tests - single samples). Next, the same biological material and two other faecal specimens fixed in 10% formalin were transported to the Military Institute of Medicine in Poland, where they were tested for Giardia intestinalis under light microscopy (direct smear, decantation in distilled water). Parasitological tests performed under light microscopy showed that 2.7% (17/630) of the study group were infected with Giardia intestinalis. Some of these results were confirmed by immunochromatographic tests (6/630). In contrast, immunoenzymatic tests (ELISA) demonstrated a significantly higher detection rate reaching 18.1% (114/630). Immunoenzymatic tests confirmed all the positive results given by light microscopy and by immunochromatographic tests. The prevalence rate of Giardia intestinalis infections in Polish soldiers deployed to Afghanistan was found to be high. Microscopic methods exhibit low sensitivity and therefore may result in the underestimation of the true parasite prevalence.

    Attention is given to the approaches which would provide the greatest chance of success in attempts related to the discovery of extraterrestrial advanced cultures in the Galaxy, taking into account the principle of least energy expenditure. The energetics of interstellar contact are explored, giving attention to the use of manned spacecraft, automatic probes, and beacons. The least expensive approach to a search for other civilizations involves a listening program which attempts to detect signals emitted by such civilizations. The optimum part of the spectrum for the considered search is found to be in the range from 1 to 2 GHz. Antenna and transmission formulas are discussed along with the employment of matched gates and filters, the probable characteristics of the signals to be detected, the filter-signal mismatch loss, surveys of the radio sky, the conduction of targeted searches.

    Many ant and termite colonies are defended by soldiers with powerful mandibles or chemical weaponry. Recently, it was reported that several stingless bee species also have soldiers for colony defence. These soldiers are larger than foragers, but otherwise lack obvious morphological adaptations for defence. Thus, how these soldiers improve colony fitness is not well understood. Robbing is common in stingless bees and we hypothesized that increased body size improves the ability to recognize intruders based on chemosensory cues. We studied the Neotropical species Tetragonisca angustula and found that large soldiers were better than small soldiers at recognizing potential intruders. Larger soldiers also had more olfactory pore plates on their antennae, which is likely to increase their chemosensory sensitivity. Our results suggest that improved enemy recognition might select for increased guard size in stingless bees. © 2017 The Author(s).

    In contrast to previous research that has primarily examined how psychological disorders (e.g., post-traumatic stress disorder [PTSD], anxiety) are affected by and affect individuals' threat perceptions, this study examines the relationship between combat experience and threat-monitoring in psychologically healthy Soldiers. Existing research has established how prolonged or intense experiences with war-related stressors can lead individuals to undergo an unconscious fear-conditioning process that affects the circuitry of the prefrontal cortex, hippocampus, amygdala, and anterior cingulate cortex regions of the brain. We predict that the intensity of one's combat experience positively influences Soldiers' attention to environmental threats. Participants included U. S. Army Soldiers with a score of 50 or below on the PTSD Checklist-Military Version. Participants completed the Combat Exposure Scale and the State-Trait Anxiety Inventory. The experimental prediction task we employed assesses the expectation of an intrusively loud white noise sound that occurred on three variable patterns in a pseudorandomized order. Each tone pattern was used 20 times over a total of 60 trials. The experimental prediction task included two neutral tones (700 and 1,300 Hz) that were presented in a repeated pattern along with a 100-dB burst of white noise (0.5-second duration). In each trial, one of three possible tone combinations was presented. To assess their attentiveness to threats, participants were asked to continuously rate their expectancy of the burst of white noise using a visual analogue scale (VAS) ranging from 0 to 100. VAS ratings were collected at controlled points throughout the task. None of the participants reported scores on any of the diagnostic surveys that met standards for clinical significance. A repeated-measures analysis of variance was conducted to assess the overall effect of the three prediction conditions on participants' VAS ratings. There was a significant

    Historical data for six selected U.S. Geological Survey streamgages along Soldier Creek in northeast Kansas were used in an assessment of streamflow characteristics and trends. This information is required by the Prairie Band Potawatomi Nation for the effective management of tribal water resources, including drought contingency planning. Streamflow data for the period of record at each streamgage were used to assess annual mean streamflow, annual mean base flow, mean monthly flow, annual peak flow, and annual minimum flow.Annual mean streamflows along Soldier Creek were characterized by substantial year-to-year variability with no pronounced long-term trends. On average, annual mean base flow accounted for about 20 percent of annual mean streamflow. Mean monthly flows followed a general seasonal pattern that included peak values in spring and low values in winter. Annual peak flows, which were characterized by considerable year-to-year variability, were most likely to occur in May and June and least likely to occur during November through February. With the exception of a weak yet statistically significant increasing trend at the Soldier Creek near Topeka, Kansas, streamgage, there were no pronounced long-term trends in annual peak flows. Annual 1-day, 30-day, and 90-day mean minimum flows were characterized by considerable year-to-year variability with no pronounced long-term trend. During an extreme drought, as was the case in the mid-1950s, there may be zero flow in Soldier Creek continuously for a period of one to several months.

    This paper describes the development and demonstration of a soldier-worn augmented reality system testbed that provides intuitive 'heads-up' visualization of tactically-relevant geo-registered icons. Our system combines a robust soldier pose estimation capability with a helmet mounted see-through display to accurately overlay geo-registered iconography (i.e., navigation waypoints, blue forces, aircraft) on the soldier's view of reality. Applied Research Associates (ARA), in partnership with BAE Systems and the University of North Carolina - Chapel Hill (UNC-CH), has developed this testbed system in Phase 2 of the DARPA ULTRA-Vis (Urban Leader Tactical, Response, Awareness, and Visualization) program. The ULTRA-Vis testbed system functions in unprepared outdoor environments and is robust to numerous magnetic disturbances. We achieve accurate and robust pose estimation through fusion of inertial, magnetic, GPS, and computer vision data acquired from helmet kit sensors. Icons are rendered on a high-brightness, 40°×30° field of view see-through display. The system incorporates an information management engine to convert CoT (Cursor-on-Target) external data feeds into mil-standard icons for visualization. The user interface provides intuitive information display to support soldier navigation and situational awareness of mission-critical tactical information.

    2015-11-01

    The Third International Congress on Soldiers' Physical Performance (ICSPP) was held on August 18-21, 2014 in Boston, MA, where it had a record attendance of 374 registrants from 27 countries. The Congress included 8 invited keynote lectures, 12 symposia, 1 featured science session, more than 200 oral and poster free communication sessions, 8 thematic poster sessions, and a Warfighter Readiness Roundtable. Collectively, the presentations focused on a fundamental premise that soldiers are the center of warfighting capability, and the human service member is the prime resource and key enabler of all warfighting systems. The intent of the ICSPP series is to focus on the soldier-the individual service member. As we move forward with focus placed on the human dimension of soldiering, the key to our scientific success and what will prove to be transformative will be the extent to which we can operationalize and disseminate our scientific knowledge for the benefit of our soldiers on the ground. The Congress fostered important scientific exchange, and dialog centered on improving military physical performance and readiness. As countries around the globe respond to current and emerging threats to their national security, it is increasingly clear that we must ensure optimal human performance of our military personnel. By taking advantage of the science and applications of physical fitness and injury prevention research, we can leverage our increased understanding for the optimal application of physical readiness processes while minimizing the injury risk potential. We believe that the continued scientific and evidence-based dialog across international partners will prove to be transformative in identifying the most effective strategies for human performance optimization in the 21st century. Innovation, leveraging current state-of-the-science, and international partnerships were all key themes throughout the Congress. From the ICSPP scientific program, it was clear that there

    Resilience Training has the potential to mitigate mental health symptoms when provided during initial military training. The present study examined the impact of Resilience Training on US soldier well-being and attitudes during Basic Combat Training. Platoons were randomly assigned to Resilience Training or Military History provided during the first few days of Basic Combat Training. Surveys were conducted at baseline, post-intervention, and 3, 6, and 9 weeks. The sample resulted in a total of 1,939 soldiers who completed at least the baseline and one follow-up survey. There were no significant differences between conditions in terms of depression symptoms, anxiety symptoms, or sleep problems. However, while anxiety decreased in both conditions, the rate of decrease was faster in the Resilience Training condition. In contrast, Resilience Training had a slower rate of increase in group cohesion over time than the Military History condition. In addition, Resilience Training was associated with greater confidence in helping others and received more positive ratings than Military History. Findings demonstrate that the brief Resilience Training studied here may have some utility in supporting mental health and peer support but may not benefit unit climate. © 2014 The International Association of Applied Psychology.

  13. Dynamics of moral judgments in young soldiers during the period of military service

    Full Text Available We have conducted an empirical study of the dynamics of the level of moral judgments in the military. Two groups of Missile Defense Force soldiers present the sample: preparing for demobilization (n=30 and new recruits (n=25. As the methods we used specially developed semi-structured interview modeling the situation of moral choice, and the questionnaire in order to assess the socio-psychological characteristics of the military and their attitude to service. The young soldiers have a positive trend in the development of moral judgments and a greater differentiation in the estimates. It is shown that the old-timers in comparison with newcomers have intensive development of group-oriented and prosocial moral reasoning. It presumably connected with successful adaptation to military service, following the manual, the ability to cope with aggressive impulses, flexibility and value assessments in decision-making. It is noted that educational work with young recruits should include measures to increase group cohesion in the army.

  14. State institutions and social identity: National representation in soldiers' and civilians' interview talk concerning military service.

    Gibson, Stephen; Condor, Susan

    2009-06-01

    Theory and research deriving from social identity or self-categorization perspectives often starts out with the presumption that social actors necessarily view societal objects such as nations or states as human categories. However, recent work suggests that this may be only one of a number of forms that societal representation may take. For example, nations may be understood variously as peoples, places, or institutions. This paper presents findings from a qualitative interview study conducted in England, in which soldiers and civilians talked about nationhood in relation to military service. Analysis indicated that, in this context, speakers were often inclined to use the terms 'Britain', 'nation', and 'country' as references to a political institution as opposed to a category of people. In addition, there were systematic differences between the ways in which the two samples construed their nation in institutional terms. The civilians were inclined to treat military service as a matter of obedience to the dictates of the Government of the day. In contrast, the soldiers were more inclined to frame military service as a matter of loyalty to state as symbolically instantiated in the body of the sovereign. Implications for work adopting a social identity perspective are discussed.

    U.S. Army mortuary affairs (MA) soldiers experience stressors of deployment and exposure to the dead, increasing risk for post-traumatic stress and depression. This study examines Troop Education for Army Morale, a postdeployment early intervention based on Psychological First Aid. MA soldiers (N = 126) were randomized to intervention or comparison groups 1-month postdeployment. Intervention sessions were held at 2, 3, 4, and 7 months. Assessments of post-traumatic stress disorder (PTSD), depression, and quality of life (QOL) were conducted at 1, 2, 3, 4, 7, and 10 months for both groups. At baseline, 25.0% of the total sample had probable PTSD (17-item PTSD Checklist M = 35.4, SD = 16.9) and 23.6% had probable depression (9-item Patient Health Questionnaire Depression Scale M = 7.8, SD = 6.9). Over 10 months, PTSD and depression symptoms decreased and QOL improved for the total sample. At study conclusion, intervention and comparison groups were not different. Intervention group males showed a transient symptom increase at 2 to 3 months. Males attended fewer intervention sessions than females. Lower attendance was associated with more symptoms and lower QOL. Higher attendance was associated with greater intervention benefits. Findings highlight the need for better understanding postdeployment interventions and facilitating attendance. Further intervention for MA soldiers is indicated.

    Full Text Available Introduction: Health related measures in emergencies are of the issues that, if taken properly, can reduce damages of a disaster effectively. To have this situation happened knowledge of health personnel, crisis staff, and military and other related groups has to improve. This study aimed to determine military staffs’ attitude and knowledge about health measures in emergencies. Methods: This descriptive and cross-sectional study was conducted through a self-administrated questionnaire. Validity and reliability of the questionnaire was previously proven. The questionnaire included items on personal information and knowledge and attitude about health measures in emergencies. Using a multi-stage sampling, 190 soldiers of Malek Ashtar Military Garrison in Arak were selected. ANOVA, Kruskal- Wallis, Chi Square, Spearman rho’s coefficient correlation and T-test were used to analyze that data. Results: Findings showed that 43 percent of soldiers had good knowledge of health measures in emergencies. About 11 percent of staff had poor knowledge. Half of staff had an average attitude toward emergency health measures. Concerning the degree of knowledge, no significant difference was observed between soldiers with different levels of education. Regarding knowledge and attitude, there was no statistically significant difference between different age groups. Conclusion: Having a basic knowledge of health measures in emergencies is of salient importance. Considering lack of such basic knowledge among some military staff, provision of training on health related measures for those staff is recommended. Keywords: knowledge, attitude, health measures, military staff, crisis

    The study was undertaken to identify risk and protective factors for suicidal ideation and suicide attempts among deployed Danish soldiers. Research on suicide among Danish veterans has only been conducted to a limited degree. The method applied was a questionnaire survey administered to a population of 1,264 Danish soldiers deployed from 1990 to 2009. The data were analyzed using backward logistic regression modeling in SAS 9.2. In the logistic regression analysis, the following were significant risk factors for suicidal ideation: drug abuse, a poor financial situation before deployment, a heavy workload and/or repatriation during deployment, and attending a poor athletic and recreation program after deployment. Significant protective factors against suicidal ideation were support from friends at home during deployment and appreciation by the general population after deployment. Significant risk factors for suicide attempts were an unhappy childhood and pointless tasks during deployment. No significant protective factors against suicide attempts were identified. On the basis of the results presented in this study, intervention against suicidal behavior would benefit from screening for certain childhood issues, drug abuse, and poor financial situation before deployment. During deployment, measures should be taken to minimize the amount of meaningless tasks and heavy workloads. At the same time, efficient ways of communicating with home should be ensured. After deployment, good athletic and recreation programs should be warranted for all military personnel-including repatriated soldiers. Finally, priority should be given to ensure public appreciation of what deployed soldiers accomplish. Reprint & Copyright © 2015 Association of Military Surgeons of the U.S.

    Meningitis and meningoencephalitis pose major risks of morbidity and mortality. To describe 20 years of experience treating infections of the central nervous system in Israel Defense Force (IDF) soldiers, including the common presentations, pathogens and sequelae, and to identify risk groups among soldiers. All soldiers who were admitted to the Hadassah University Medical Center (both campuses: Ein Kerem and Mt. Scopus) due to meningitis and meningoencephalitis from January 1993 to January 2014 were included in this retrospective study. Clinical, laboratory and radiologic data were reviewed from their hospital and army medical corps files. Attention was given to patients' military job description, i.e., combat vs. non-combat soldier, soldiers in training, and medical personnel. We identified 97 cases of suspected meningitis or meningoencephalitis. Six were mistakenly filed and these patients were found to have other disorders. Four soldiers were diagnosed with epidural abscess and five with meningitis due to non-infectious in flammatory diseases. Eighty-two soldiers in active and reserve duty had infectious meningitis or meningoencephalitis. Of these, 46 (56.1%) were combat soldiers and 31 (37.8%) non-combat; 20 (29.2%) were soldiers in training, 10 (12.2%) were training staff and 8 (9.8%) were medical staff. The main pathogens were enteroviruses, Epstein-Barr virus an d Neisseria meningitidis. In our series, soldiers in training, combat soldiers and medical personnel had meningitis and meningoencephalitis more than other soldiers. Enteroviruses are highly infectious pathogens and can cause outbreaks. N. meningitidis among IDF soldiers is still a concern. Early and aggressive treatment with steroids should be considered especially in robust meningoencephalitis cases.

  20. [A historical medical study of post-traumatic stress disorders in World War I soldiers].

    Lemke, S

    2007-01-01

    The concept of post-traumatic stress disorder (PTSD) was to be verified considering World War I soldiers suffering from psychiatric and neurologic diseases. According to hypotheses, relevant circumstances of the case history and significance of the direct military action had to be examined. In 2002, medical histories dating from 1914 to 1921 of male soldiers in Jena, Germany, were analyzed. Statistical examination carried out by means of the chi2 test revealed mental illness more frequently in soldiers with relevant family anamnesis, previous psychiatric treatment, or degree of voluntariness than in soldiers not so characterized. The accumulation of mental illnesses was lower in soldiers involved in military actions or directly with firing weapons than in soldiers never involved in battles. These results are in accord with historical but not current literature on PTSD. The author is of the opinion that psychiatric anamnesis is not given enough consideration in the concept of PTSD.

  1. The Bluebirds: World War I Soldiers' Experiences of Occupational Therapy.

    Pettigrew, Judith; Robinson, Katie; Moloney, Stephanie

    More is known about the experience of occupational therapists than the experience of patients during the profession's early years. We examined soldiers' experiences of occupational therapy in American Base Hospital 9 in France during World War I through analysis of a 53-line poem by Corporal Frank Wren contained in the unpublished memoir of occupational therapy reconstruction aide Lena Hitchcock. Historical documentary research methods and thematic analysis were used to analyze the poem, the memoir, and the hospital's published history. The poem describes the activities engaged in during occupational therapy, equipment used, and the context of therapy. It articulates positive dimensions of the experience of engaging in activities, including emotional benefits, diversion, and orthopedic benefits. Previous historical research has identified core philosophical premises about the use of occupational therapy; in this article, the enactment of these principles is established through the analysis of a soldier's account of receiving occupational therapy.

    Full Text Available The family Cantharidae is a worldwide distributed group of flattened and soft-bodied beetles displaying aposematic colouration. These beetles, commonly known as soldier beetles, have an extensive fossil record dating back to the Lower Cretaceous. The majority of fossil material, referred to Cantharidae, is known from amber inclusions. In this paper we describe and illustrate a new soldier beetle Kuskaella macroptera gen. et sp. nov. from the Baltic amber. It is characterised by pronotum of the male parallel-sided in basal third and abruptly narrowed towards apex, and of the female gradually and steadily narrowing from the basal margin to the apex; globular head; unequal maxillary palpomeres with the last segment elongated-globular and pointed; long elytra slightly surpassing the last abdominal segment. This finding is the first described species of both sexes preserved in a single amber piece.

  3. The German-Jewish soldier: from participant to victim.

    2011-01-01

    The story of German-Jewish soldiers and veterans of World War I illustrates how, under circumstances of inclusion (even if incomplete) rather than vicious persecution, Jewish suffering in wartime, and with it the forms of collective memory and strategies for commemoration of the dead, could closely parallel, even intersect with, the suffering of Germans as a whole. To be sure, the points of intersection were accompanied by points of deflection. Even when Jews served, fought, suffered and died as German soldiers, their interpretations of the war experience, and their communities’ postwar memory and commemorative practices, differed from those of other Germans. In many ways, however, German-Jewish veterans suffered the aftermath of the war as did other Germans; they shared the prevailing fury over war guilt and reparations, and they retained a strong pride in their military service, a pride through which they interpreted the events of 1933–1945.

    Numerous studies have shown an association between asthma and mental disorders. While elevated rates of asthma have been noted among psychiatric patients with anxiety disorders and post-traumatic stress disorder, several studies have found elevated rates of mental disorders among asthma patients. Such studies, however, have generally relied upon questionnaires and assessment by non-specialist physicians to diagnose mental disorders and asthma. To examine a possible association between asthma and psychiatric diagnoses in Israeli military recruits and soldiers. In this cross-sectional study we compared the prevalence of mental diagnoses in asthmatic recruits and soldiers with that in non-asthmatic recruits and soldiers. A total of 195,903 recruits and soldiers were examined by Israel Defense Forces recruiting offices and fitness boards. Diagnoses of asthma were based on a pulmonologist's diagnosis, including spirometry at rest and exercise testing as indicated; diagnoses of mental disorders were based on examination by a psychiatrist. The prevalence of asthma was found to be 7.8% (current) and 9.8% (lifetime). The prevalence of mental disorders was 13.4%. Current asthma was associated with an increased likelihood of any mental disorder (OR = 1.20, 95% Cl = 1.15-1.26), and specifically with mood and anxiety disorders (1.31, 1.19-1.46), introvert personality disorders (1.20, 1.12-1.28) and adjustment disorder (1.43, 1.26-1.62). Lifetime asthma was associated with an increased likelihood of the same disorders, but the association was not as powerful. The results validate the previously documented association between asthma and mental disorders, using a sample of unprecedented size and improved methodology. A multidisciplinary approach to asthma that incorporates mental health professionals in the treatment of poorly controlled asthma and perhaps of asthma in general is recommended.

    In the second Lebanon war in 2006, the Israeli Defense Forces fought against well-prepared and well-equipped paramilitary forces. The conflict took place near the Israeli border and major Israeli medical centers. Good data records were maintained throughout the campaign, allowing accurate analysis of injury characteristics. This study is an in-depth analysis of injury mechanisms, severity, and anatomic locations. Data regarding all injured soldiers were collected from all care points up to the definitive care hospitals and were cross-referenced. In addition, trauma branch physicians and nurses interviewed medical teams to validate data accuracy. Injuries were analyzed using Injury Severity Score (ISS) (when precise anatomic data were available) and multiple injury patterns scoring for all. A total of 833 soldiers sustained combat-related injury during the study period, including 119 fatalities (14.3%). Although most soldiers (361) sustained injury only to one Abbreviated Injury Scale (AIS) region, the average number of regions per soldier was 2.0 but was 1.5 for survivors versus 4.2 for fatalities. Current war injury classifications have limitations that hinder valid comparisons between campaigns and settings. In addition, limitation on full autopsy in war fatalities further hinders data use. To partly compensate for those limitations, we have looked at the correlation between fatality rates and number of involved anatomic regions and found it to be strong. We have also found high fatality rates in some "combined" injuries such as head and chest injuries (71%) or in the abdomen and an extremity (75%). The use of multiinjury patterns analysis may help understand fatality rates and improve the utility of war injury analysis. Epidemiologic study, level III.

    Full Text Available Objective: Military service is a highly stressful period both for the soldiers serving and for their parents. Surprisingly, parents’ experience has been mostly ignored in the research. This study’s goal is to shed light on the experience and distress levels of parents of active duty combat soldiers during Operation Protective Edge, a military operation carried out by the Israel Defense Forces during July and August of 2014.Methods: During the advanced stages of the operation, 69 parents of Israeli male combat soldiers (55 mothers and 14 fathers completed an online survey measuring symptoms of Posttraumatic Stress Disorder (PTSD-Checklist-5 and distress (Brief Symptom Inventory-18. Participants were recruited using a convenience sample, by posting ads on the public Facebook pages of the researchers and of the groups dedicated to parents of Israeli soldiers.Results: Parents’ depression and anxiety symptom levels were higher than depression and anxiety symptom levels of the adult community norms in Israel. General distress rates of parents were similar to those presented by adults in southern Israel who were exposed for 7 years to the ongoing threat of daily rocket fire from Gaza, and higher than rates of a non-threatened Israeli population. Finally, 20.2% of the parents presented PTSD-like symptoms, a higher percentage than the probable PTSD diagnosis rates that were found in the general population in Israel during previous terror waves.Conclusion: This study provides preliminary evidence of soldiers’ parents’ distress and indicates the need for a better understanding of the impact of military service on soldiers’ parents.

    Although not traditionally recognized as such, trematode infections in molluscan first intermediate hosts comprise colonies. When two trematode species simultaneously infect a snail host, one generally kills the other. Thus, there can be strong selective pressure for established trematode colonies to protect and defend against new infections. Recent findings demonstrate that some trematode species have a reproductive division of labor involving a reproductive and a soldier caste. Reproductives are larger and filled with offspring, while soldiers lack developing embryos, and are specialized for inter-trematode antagonism. This reproductive division of labor has now been documented for intramolluscan stages of fourteen trematode species from different geographic regions and host species. Further, literature descriptions of the life history of several species suggest that this phenomenon is widespread, although there are important intra- and inter-specific differences in colony structure. It has been predicted that trematode soldier castes would most likely evolve in taxa that are typically dominant in interspecific hierarchies, in situations of invasion risk, and among trematodes that infect longer lived hosts. Here I address these hypotheses and present the extent of evidence for trematode social organization.

    Human performance enhancement was the subject of a NATO workshop that considered the direct benefits of individual soldier health and fitness habits to brain health and performance. Some of the important health and fitness include physical activity and purposeful exercise, nutritional intake, sleep and rest behaviors, psychological outlook and mindfulness, and other physiologically based systemic challenges such as thermal exposure. These influences were considered in an integrated framework with insights contributed by each of five participating NATO member countries using representative research to highlight relevant interrelationships. Key conclusions are that (1) understanding the neurobiological bases and consequences of personal health behaviors is a priority for soldier performance research, and this also involves long-term brain health consequences to veterans and (2) health and fitness habits have been underappreciated as reliably effective performance enhancers and these should be preferred targets in the development of scientifically based recommendations for soldier brain health and performance.

  20. Limitations imposed by wearing armour on Medieval soldiers' locomotor performance.

    Science.gov (United States)

    Askew, Graham N; Formenti, Federico; Minetti, Alberto E

    2012-02-22

    In Medieval Europe, soldiers wore steel plate armour for protection during warfare. Armour design reflected a trade-off between protection and mobility it offered the wearer. By the fifteenth century, a typical suit of field armour weighed between 30 and 50 kg and was distributed over the entire body. How much wearing armour affected Medieval soldiers' locomotor energetics and biomechanics is unknown. We investigated the mechanics and the energetic cost of locomotion in armour, and determined the effects on physical performance. We found that the net cost of locomotion (C(met)) during armoured walking and running is much more energetically expensive than unloaded locomotion. C(met) for locomotion in armour was 2.1-2.3 times higher for walking, and 1.9 times higher for running when compared with C(met) for unloaded locomotion at the same speed. An important component of the increased energy use results from the extra force that must be generated to support the additional mass. However, the energetic cost of locomotion in armour was also much higher than equivalent trunk loading. This additional cost is mostly explained by the increased energy required to swing the limbs and impaired breathing. Our findings can predict age-associated decline in Medieval soldiers' physical performance, and have potential implications in understanding the outcomes of past European military battles.

    Full Text Available In 1763, a regiment of mercenary soldiers stationed on the border of Suriname and Berbice in South America, rebelled. The men had been sent to help subdue a large slave rebellion. Instead, they mutinied and joined the rebelling slaves. This paper reconstructs the mutiny from Dutch records and uses it to look at the role of soldiers as border crosser in the Atlantic world. Colonial historians have usually studied soldiers in their capacity of border enforcers, men who maintained the cultural and legal divisions that supported colonial authority. However, as I show, soldiers with great regularity crossed those same borders, threatening the very foundations of colonialism.

    The Turkish Armed Forces Commando Brigade has started a continuous and systematic education program, called the Patriotic Awareness Acquirement Project (PCAP), to inform soldiers who will be demobilized. Within the PCAP, topics such as Turkish history, the Armenian question, and manners/etiquette, as well as healthy living, reproductive health, family planning, general hygiene, and sexually transmitted diseases were included. The aim of Reproductive Health Education (RHE) conducted within the PCAP is to inform male individuals about reproductive health and to increase their knowledge, awareness, and sensitivity. In the RHE, the privates were provided with information regarding male and female reproductive organs, the menstruation mechanism, pregnancy, determination of gender, fertility-infertility, and sexually transmitted diseases. After the evaluation, it was reported that the privates indicated they were satisfied with RHE, were informed, took notice of the incorrect information, and, for postmilitary life, would visit health clinics for counseling.

    War experiences (WE) and postwar environments (PWE) are associated with mental ill-health. The present study aims to investigate the pathways from WE and PWE to mental ill-health and to define opportunities for intervention through analysis of the war-affected youths study (WAYS) cohort study. WAYS is an ongoing study of a large cohort of former child soldiers being conducted in Uganda. Mental health problems, subjective WE and PWE contexts were assessed by local adaptations of internationally developed measures for use with former child soldiers at least 6 years after the end of the war. Structural equation modeling was used to test two mediation hypotheses: (1) the 'trauma model' in which WE directly influence long-term mental health and (2) the 'psychosocial path' in which WE influence long-term mental health through PWE stressors. WE were linked to depression/anxiety (β=0.15 (95% CI 0.01 to 0.30)) through PWE (accounting for 44% of the variance in the relationship between these variables) and to conduct problems (β=0.23 (95% CI 0.03 to 0.43); (accounting for 89% of the variance, ie, near complete mediation)). The direct relation between WE and depression/anxiety attenuated but remained statistically significant. For conduct problems, the direct relationship was no longer significant after accounting for PWE. PWE are a key determinant of continued mental health problems in former child soldiers. Interventions to reduce long-term mental problems should address both PWE stressors (psychosocial model) and specialised mental healthcare (trauma model) and consider both models of intervention as complementary.

    To describe strategies for a comprehensive literature search. MEDLINE searches result in limited numbers of studies that are often biased toward statistically significant findings. Diversified search strategies are needed. Empirical evidence about the recall and precision of diverse search strategies is presented. Challenges and strengths of each search strategy are identified. Search strategies vary in recall and precision. Often sensitivity and specificity are inversely related. Valuable search strategies include examination of multiple diverse computerized databases, ancestry searches, citation index searches, examination of research registries, journal hand searching, contact with the "invisible college," examination of abstracts, Internet searches, and contact with sources of synthesized information. Extending searches beyond MEDLINE enables researchers to conduct more systematic comprehensive searches.

    The aim of the survey was to establish whether PTSD is present among Polish soldiers returning from a one-year deployment to Iraq and an analysis of its individual symptoms. Sixty soldiers were examined, including 30 who returned from the Iraqi mission and 30 who remained in Poland. Five analysing devices were used: (IPSA), (STAI), (BDI), a PTSD questionnaire and a socio-demographical form. A significant number of soldiers experienced a traumatic event during the mission in Iraq. Although the Iraq deployment did not change the level of depression and anxiety among the two groups of soldiers, disproportions were found in the range of anger level intensity, which was significantly higher among soldiers who returned from Iraq. Stabilisation mission and the experience of a traumatic event influenced the biological and psychological functioning patterns among soldiers who returned from Iraq. The manifestations of this were emotional and physiological reactions that the soldiers experienced (nightmares, excessive sweating, increased heartbeat rate, stressful reactions in situations similar to the traumatic occurrence and intensified responses to them). However, contrary to the assumptions, it was not concluded that soldiers who returned from Iraq are suffering from PTSD.

    Full Text Available Background: During the period between 1993 and 2005, the people of Burundi were trapped within a violent civil war. In post-conflict regions, symptoms of posttraumatic stress disorder (PTSD were found to be widespread. At the same time, combatants often reported having perceived committing violence as exciting and appealing, an experience referred to as appetitive aggression. Both of these phenomena hamper the building of a functional and peaceful society. Objective: This study aims to investigate the factors that are associated with the level of PTSD and appetitive aggression in former and still active combatants. Methods: Semi-structured interviews were conducted with 948 male Burundians: 556 active soldiers and 392 ex-combatants. PTSD symptom severity was assessed using the PTSD Symptom Scale Interview, while appetitive aggression was assessed using the Appetitive Aggression Scale. Results: Linear regression analyses revealed that the number of traumatic events, childhood maltreatment, and their interaction predicted PTSD symptom severity, whereas self-committed violence did not. The number of traumatic events and self-committed violence were associated with appetitive aggression. Childhood maltreatment alone was not associated with appetitive aggression; however, its interaction with self-committed violence did predict appetitive aggression. When controlling for predictors, ex-combatants reported a higher degree of PTSD symptomatology, whereas active soldiers reported a higher degree of appetitive aggression. Conclusion: We conclude that childhood maltreatment is an additional, significant risk factor that exacerbates the psychological consequences of violent conflicts. Self-committed violence may not necessarily engender trauma-related disorders, but is highly related to appetitive aggression.

  1. Examination of soldier target recognition with direct view optics

    Target recognition and identification is a problem of great military and scientific importance. To examine the correlation between target recognition and optical magnification, ten U.S. Army soldiers were tasked with identifying letters on targets at 800 and 1300 meters away. Letters were used since they are a standard method for measuring visual acuity. The letters were approximately 90 cm high, which is the size of a well-known rifle. Four direct view optics with angular magnifications of 1.5x, 4x, 6x, and 9x were used. The goal of this approach was to measure actual probabilities for correct target identification. Previous scientific literature suggests that target recognition can be modeled as a linear response problem in angular frequency space using the established values for the contrast sensitivity function for a healthy human eye and the experimentally measured modulation transfer function of the optic. At the 9x magnification, the soldiers could identify the letters with almost no errors (i.e., 97% probability of correct identification). At lower magnification, errors in letter identification were more frequent. The identification errors were not random but occurred most frequently with a few pairs of letters (e.g., O and Q), which is consistent with the literature for letter recognition. In addition, in the small subject sample of ten soldiers, there was considerable variation in the observer recognition capability at 1.5x and a range of 800 meters. This can be directly attributed to the variation in the observer visual acuity.

    Four different types of childhood maltreatment were examined as predictors of unwanted sexual experiences and acknowledged sexual harassment among male and female active duty soldiers in the United States Army. Predictor variables included childhood sexual abuse, physical-emotional abuse, physical neglect, and emotional neglect. Three types of unwanted sexual experiences in the workplace were examined as outcome variables: gender harassment, unwanted sexual attention, and coercion. Both sexual and physical-emotional abuse during childhood were found to be predictors of unwanted sexual experiences and of acknowledged sexual harassment in the workplace. Among female soldiers, the most severe type of unwanted experience-coercion-was predicted only by childhood physical-emotional abuse. Among male soldiers childhood sexual abuse was the strongest predictor of coercion. A greater variety of types of childhood maltreatment predicted sexual harassment outcomes for male soldiers. Childhood maltreatment and adult sexual harassment were predictors of psychological well-being for soldiers of both genders.

    U.S. Army Special Operations Forces (SOF) soldiers deploy frequently and conduct military operations through special warfare and surgical strike capabilities. Tasks required to execute these capabilities may induce physical and mental stress and have the potential to degrade soldier physiological status. No investigations have longitudinally characterized whether combat deployment alters anthropometrics or biochemical markers of physiological status in a SOF population of frequent deployers. Effects of modern combat deployment on longitudinal changes in anthropometrics and physiological status of elite U.S. Army SOF soldiers (n = 50) were assessed. Changes in measures of body composition, grip strength, physiological status, and health behaviors from baseline to postdeployment were determined with paired t test and McNemar's statistic. Baseline measures were obtained between 4 and 8 weeks before deployment. Deployment length was a uniform duration of time between 3 and 6 months (all soldiers completed the same length of deployment). Post hoc analyses determined change in body mass within quartiles of baseline body mass with paired t test and associations between change in sex hormone-binding globulin (SHBG) and change in body mass with correlation coefficient. The study was approved by the Human Use Review Committee at the U.S. Army Research Institute of Environmental Medicine, Natick, Massachusetts. In response to deployment, increases in lean mass (77.1 ± 7.6 to 77.8 ± 7.5 kg), maximum grip strength (57.9 ± 7.2 to 61.6 ± 8.8 kg), and conduct of aerobic (156 ± 106 to 250 ± 182 minutes/week) and strength training (190 ± 101 to 336 ± 251 minutes/week) exercise were observed (p < 0.05). Increases in serum SHBG (35.42 ± 10.68 to 38.77 ± 12.26 nmol/L) and decreases in serum cortisol (443.2 ± 79.3 to 381.9 ± 111.6 nmol/L) were also observed (p < 0.05). Body mass changes were dependent on baseline body mass. Soldiers in the lowest quartile of baseline body

    The military has identified Human Performance Modeling (HPM) as a significant requirement and challenge of future systems modeling and analysis initiatives as can be seen in the Department of Defense's (DoD) Defense Modeling and Simulation Office's (DMSO) Master Plan (DoD 5000.59-P 1995). To this goal, the military is currently spending millions of dollars on programs devoted to HPM in various military contexts. Examples include the Human Performance Modeling Integration (HPMI) program within the Air Force Research Laboratory, which focuses on integrating HPMs with constructive models of systems (e.g. cockpit simulations) and the Navy's Human Performance Center (HPC) established in September 2003. Nearly all of these initiatives focus on the interface between humans and a single system. This is insufficient in the era of highly complex network centric SoS. This report presents research and development in the area of HPM in a system-of-systems (SoS). Specifically, this report addresses modeling soldier fatigue and the potential impacts soldier fatigue can have on SoS performance.

    Given the stressful nature of military life, people in the armed forces are vulnerable to substance use. The aim of this study was to explore the relationship between family and peers with drug use among military forces in Iran. Convenience sampling was used to recruit a total of 422 draftees doing military service in army units in Tehran, Iran. Measures of family and peers' risk and protective factors, alcohol use, and other drug use were administered. Findings indicated significant relationships between family (i.e., family models for risk behavior, parent sanctions, and family controls) and peers (i.e., peer modeling for risk behavior, peer controls, support from friends) with drug use. A multiple regression analysis revealed that peer modeling for risk behavior, family models for risk behavior, and parent sanctions were significant predictors of drug use in soldiers. These results were consistent with the influence of family and peer on drug use amongst soldiers. Programs designed to reduce alcohol and other drug use may benefit from tailoring to fit risk and protective files amongst peer and family networks.

    Social support, including support from spouses, may buffer against posttraumatic stress disorder (PTSD) symptoms. The current study assessed whether the frequency of spousal communication during a recent deployment, a potentially important source of support for soldiers, was related to postdeployment PTSD symptoms. Data came from 193 married male Army soldiers who returned from military deployment within the past year. For communication modalities conceptualized as delayed (i.e., letters, care packages, and e-mails), greater spousal communication frequency during deployment was associated with lower postdeployment PTSD symptom scores, but only at higher levels of marital satisfaction (p = .009). At lower marital satisfaction, more delayed spousal communication during deployment was associated with more PTSD symptoms (p = .042). For communication modalities conceptualized as interactive (i.e., phone calls, instant messaging, instant messaging with video), the same general direction of effects was seen, but the interaction between communication frequency and marital satisfaction predicting PTSD symptoms did not reach significance.

    Hand dermatitis in soldiers is a considerable problem. The purpose of the study was to evaluate appropriate screening tests to improve the diagnosis of hand dermatitis in soldiers. A group of 111 soldiers with occupational dermatitis from contact with fuels and oils underwent "tailored patch tests" with allergens relevant to their field of work and their environment. The control group consisted of 24 soldiers with various jobs similar to those of civilian life, who had not been exposed to oils and fuels. Seventy-three civilian patients, attending the clinic for patch testing, were also included. Twenty soldiers, who had a history of intensive contact with oil and fuels, but no contact dermatitis, and who were admitted because of various skin diseases (fungal infections, acne, etc.) also underwent the supplemental testing and served as an additional control group. Of the soldiers, 31 (29%) showed one or more positive skin tests of the oil series and 30 patients of this group one or more positive reactions to the standard patch tests trays. No patient of the control groups had a positive test to the oil series. Our results show the value of the supplementary tests as a first-step screening test for detection of oil allergy in soldiers and automobile-mechanics or in workers handling other gasoline- or diesel-powered engineering equipment. The test method appears to be practical, easy to perform, reliable and giving clear and accurate results, with a negligible rate of false positive reactions.

    Biomarkers allowing the identification of individuals with an above average vulnerability or resilience for posttraumatic stress disorder (PTSD) would especially serve populations at high risk for trauma exposure like firefighters, police officers and combat soldiers. Aiming to identify the most promising putative PTSD vulnerability markers, we conducted the first systematic review on potential imaging and non-genetic molecular markers for PTSD risk and resilience. Following the PRISMA guidelines, we systematically screened the PubMed database for prospective longitudinal clinical studies and twin studies reporting on pre-trauma and post-trauma PTSD risk and resilience biomarkers. Using 25 different combinations of search terms, we retrieved 8151 articles of which we finally included and evaluated 9 imaging and 27 molecular studies. In addition, we briefly illustrate the design of the ongoing prospective German Armed Forces (Bundeswehr) PTSD biomarker study (Bw-BioPTSD) which not only aims to validate these previous findings but also to identify novel and clinically applicable molecular, psychological and imaging risk, resilience and disease markers for deployment-related psychopathology in a cohort of German soldiers who served in Afghanistan.

    As the volume of electronically available information grows, relevant items become harder to find. This work presents an approach to personalizing search results in scientific publication databases. This work focuses on re-ranking search results from existing search engines like Solr or ElasticSearch. This work also includes the development of Obelix, a new recommendation system used to re-rank search results. The project was proposed and performed at CERN, using the scientific publications available on the CERN Document Server (CDS). This work experiments with re-ranking using offline and online evaluation of users and documents in CDS. The experiments conclude that the personalized search result outperform both latest first and word similarity in terms of click position in the search result for global search in CDS.

    Combat deployments are characterized by high operational demands with limited opportunities for sleep leading to fatigue and degraded cognitive and operational performance. Caffeine in moderate doses is recognized as an effective intervention for physical and cognitive decrements associated with sleep loss. This report is based on data collected by two separate, independently conducted surveys administered in Afghanistan in 2011-2012. It assessed caffeine use and sleep disruption among U.S. Army combat soldiers (J-MHAT 8; n = 518) and among deployed soldiers with different military assignments (USARIEM Deployment Survey; n = 260). Daily caffeine intake assessed in the J-MHAT 8 survey averaged 404 ± 18 mg. In the USARIEM Deployment Survey, intake was 303 ± 29 mg and was significantly higher among combat arms soldiers (483 ± 100 mg) compared to combat service support personnel (235 ± 23 mg). In both surveys, over 55% of total caffeine intake was from energy drinks. Additional sources of caffeine included coffee, tea, sodas, gum, candy, and over-the-counter medications. Higher caffeine intake was not associated with ability to fall asleep at night or wake-up in the morning (J-MHAT 8 survey). Higher caffeine consumption was associated with disrupted sleep from high operational tempo and nighttime duties of combat operations. Overall caffeine consumption and energy drink use in Afghanistan was greater than among non-deployed soldiers and civilians. Caffeine was frequently used as a countermeasure during night operations to offset adverse effects of sleep loss on physical and cognitive function, consistent with current Department of the Army recommendations.

  15. For soldier and state: dual loyalty and World War One.

    2012-01-01

    Military medicine has always been characterized by some form of dual loyalty: physicians have to consider the interests of the individual soldier--patient as well as the interests of the state and the military in general. The way in which each individual doctor responds to this dual loyalty has mostly been viewed as a product of war circumstances on the one hand, and the personal character and/or religious and ideological beliefs of the physician on the other. Taking World War One as an example, this article argues that the nature of the illness or wound also had a part to play in this. The article shows that the disfigured were looked upon mainly in relation to the patient's own interests; the invalided-out through a combination of the patient's as well as the state's interests; and the neurotic mainly out of concern for the interests of the state.

    The Soldier-Warfighter Operationally Responsive Deployer for Space (SWORDS) project was a joint project between the U.S. Army Space & Missile Defense Command (SMDC) and NASA. The effort, lead by SMDC, was intended to develop a three-stage liquid bipropellant (liquid oxygen/liquid methane), pressure-fed launch vehicle capable of inserting a payload of at least 25 kg to a 750-km circular orbit. The vehicle design was driven by low cost instead of high performance. SWORDS leveraged commercial industry standards to utilize standard hardware and technologies over customized unique aerospace designs. SWORDS identified broadly based global industries that have achieved adequate levels of quality control and reliability in their products and then designed around their expertise and business motivations.

    The study of organic and psychological response during combat situations has been poorly reported despite its importance for soldiers training and specific instruction, so it was proposed as aim of the present investigation to analyze the effect of a tactical parachute simulated jump in psycho-physiological response of paratroopers' warfighters during an urban combat simulation. 19 male paratroopers (31.9 ± 6.2 year old; 173.6 ± 5.3 cm; 73.8 ± 8.3 Kg) of the Spanish Army were divided in two groups: parachute jump group (n:11) that conducted a simulated parachute jump and a urban combat maneuver and a non-parachute jump group (n:8) that only conducted an urban combat maneuver. We analyzed before and after the maneuver the rated perceived exertion, legs strength manifestation, blood lactate, cortical activation, heart rate variability, blood oxygen saturation and pressure, skin temperature, fine motor skills, and anxiety state. A tactical parachute simulated jump prior to an urban combat maneuver produce significantly (p jump situation in professional Army paratroopers. Independently of the parachute jump, an urban combat maneuver produces a significant increase in rated perceived exertion, blood lactate, heart rate, legs strength, sympathetic modulation and anxiety response as well as a significant decrease in blood oxygen saturation and parasympathetic modulation.

    Full Text Available A few countries permit women to serve in combat roles, but their long term performance in these positions has not been reported. The incidences of overuse injuries and attrition of 85 male and 235 female recruits in a light infantry brigade was followed in a three-year prospective study. Females were shorter (162 cm, CI 161–163 cm than males (174 cm, CI 173–176, had more body fat (18.9 kg, CI 18.2–19.6 kg than males (12.6 kg, 11.3–13.8 kg, had lower V˙O2max (36.8 mL·min−1·kg−1, CI 35.8–37.78 mL·min−1·kg−1 than males (50.48 mL·min−1·kg−1, CI 48.4 to 52.48 mL·min−1·kg−1, had more stress fractures (21.0%, 95% CI 16.2–26.5% than males (2.3%, CI 0.3–8.2%, and had more anterior knee pain (41.2%, CI 34.9–47.7% than males (24.7%, CI 16.0–35.2%. Three-year attrition was 28% CI 22–34% for females and 37% CI 26–48% for males. The females in this study successfully served as light infantry soldiers. Their lower fitness and high incidence of overuse injuries might impede service as regular infantry soldiers.

    In the last decade the Military Health System has changed its paradigm to focus on health promotion and disease prevention. This paper reviews a decade of research exploring the effects of military life on nutritional status and bone health of Army soldiers. Descriptive and experimental approaches have assessed occupational demands on soldiers in variable environments that require optimal nutrition status and physical health. The prevalence of overweight and obesity in the military has risen dramatically and the implications for health, readiness, productivity, and cost demands attention. The related nutritional deficits such as suboptimal vitamin D status likely contribute to musculoskeletal injuries which have a greater impact on the performance and readiness of soldiers than any other medical condition in peacetime or conflict. The greatest challenge in our system for health is optimizing the performance of all soldiers while minimizing health risks and long-term disability resulting from occupational hazards, particularly those inherent to war.

    Full Text Available The objective of the research was to find a correlation between motor abilities and working efficiency of soldiers in a battle unit of Slovenia Armed Forces (SAF. The subject consisted of 115 soldiers (age = 27,1 ± 3,7 years who were serving in the first brigade of the SAF. Motor abilities were measured with 11 motor tests, assessing the level of flexibility, speed, strength and coordination. To evaluate working efficiency of soldiers a special questionnaire was used, which consisted of 19 statements. Superior officer was asked to fill a questionnaire for each inferior soldier with values from 1 to 5. The correlation between motor abilities and working efficiency was assessed with the Pearson’s correlation coefficient. We have found 5 statistically significant correlations. Motor tests correlating most with working performance were tests of arm strength.

Respiratory and gastrointestinal symptoms are the most frequent encountered complaints among soldiers. Main causes that led them to try quitting were health concerns and financial issues; as most of them spend a considerable percentage of their monthly income to obtain cigarettes. Unfortunately there was no organized positive support to help the quitters.

    Short sleep duration (SSD) is common among deployed soldiers. The prevalence of SSD during redeployment, however, is unknown. Cross-sectional study of a brigade combat team (n = 3152 US Army soldiers) surveyed 90-180 days after completing a 6-15 month deployment to Iraq as part of Operation Iraqi Freedom (OIF). Survey items targeted sleep habits and comorbid medical conditions. Multivariate logistic regression analyses were performed to calculate adjusted odds ratios of medical comorbidities associated with SSD. US Army Infantry Post. All soldiers from a redeploying brigade combat team participated in a health assessment between 90 and 180 days upon return to Ft. Lewis from Iraq. None. A total of 2738 (86.9%) soldiers answered questions regarding self-perceived sleep and were included in the analysis. Mean sleep duration was 5.8 ± 1.2 hours. Nineteen hundred fifty-nine (72%) slept ≤ 6 h, but only 16% reported a daytime nap or felt their job performance was affected due to lack of sleep. Short sleep was more common among soldiers who reported combat exposure. After controlling for combat exposure, short sleep duration (SSD) was associated with symptoms of depression, posttraumatic stress disorder, panic syndrome, and with high-risk health behaviors such as abuse of tobacco and alcohol products, and suicide attempts. SSD is common among redeployed soldiers. Soldiers who experienced combat are at increased risk for persistent SSD and comorbidities associated with SSD. Efforts to reestablish good sleep habits and aggressive evaluation of soldiers with persistent SSD following deployment may aid in the prevention and management of associated medical conditions.

    2014-09-01

    We characterized trends in mental health services utilization and stigma over the course of the Afghanistan and Iraq wars among active-component US soldiers. We evaluated trends in mental health services utilization and stigma using US Army data from the Health-Related Behavior (HRB) surveys from 2002, 2005, and 2008 (n = 12,835) and the Land Combat Study (LCS) surveys administered to soldiers annually from 2003 to 2009 and again in 2011 (n = 22,627). HRB and LCS data suggested increased mental health services utilization and decreased stigma in US soldiers between 2002 and 2011. These trends were evident in soldiers with and without posttraumatic stress disorder (PTSD), major depressive disorder (MDD), or PTSD and MDD. Despite the improving trends, more than half of soldiers with mental health problems did not report seeking care. Mental health services utilization increased and stigma decreased over the course of the wars in Iraq and Afghanistan. Although promising, these findings indicate that a significant proportion of US soldiers meeting criteria for PTSD or MDD do not utilize mental health services, and stigma remains a pervasive problem requiring further attention.

    This study examined rates of utilization of mental health care among active duty and National Guard soldiers with mental health problems three and 12 months after they returned from combat in Iraq. Stigma and barriers to care were also reported for each component (active duty and National Guard). Cross-sectional, anonymous surveys were administered to 10,386 soldiers across both time points and components. Mean scores from 11 items measuring stigma and barriers to care were computed. Service utilization was assessed by asking soldiers whether they had received services for a mental health problem from a mental health professional, a medical doctor, or the Department of Veterans Affairs in the past month. Risk of mental problems was measured using the Patient Health Questionnaire, the PTSD Checklist, and items asking about aggressive behaviors and "stress, emotional, alcohol, or family" problems within the past month. A higher proportion of active duty soldiers than National Guard soldiers reported at least one type of mental health problem at both three months (45% versus 33%) and 12 months (44% versus 35%) postdeployment. Among soldiers with mental health problems, National Guard soldiers reported significantly higher rates of mental health care utilization 12 months after deployment, compared with active duty soldiers (27% versus 13%). Mean stigma scores were higher among active duty soldiers than among National Guard soldiers. Active duty soldiers with a mental health problem had significantly lower rates of service utilization than National Guard soldiers and significantly higher endorsements of stigma. Current and future efforts to improve care for veterans should work toward reducing the stigma of receiving mental health care.

    The mortality rate of men is generally higher than that of women, irrespective of the age group. Currently, a key concern for health care professionals is the prevalence of risk factors associated with cardiovascular disease and metabolic syndrome. This study aimed at assessing the prevalence of individual risk factors for cardiovascular disease as well as the prevalence of metabolic syndrome among men serving in the Military Police Corps of the state of Bahia, Brazil. This service employs mostly men, and they are known to experience high levels of occupational stress and professional victimization. We conducted a cross-sectional study among military police soldiers (n = 452) who were candidates for a military police training course in Bahia, Brazil. All candidates who attended the selection process were evaluated according to the criteria of the National Cholesterol Education Program's Adult Panel III in order to assess the presence of medical disorders that could contribute to cardiovascular disease and metabolic syndrome. The authors identified a high prevalence of hypertension (55.76%), hypertriglyceridemia (50.85%), waist circumference of >102 cm (31.76%), low high-density lipoprotein cholesterol levels (30.46%), and impaired fasting glucose (28.15%) in our subjects. The overall prevalence of metabolic syndrome was 38.54%. The authors suggest that measures should be taken to ensure that military policemen receive continued medical care, both in their professional capacity and in their personal circumstances, and that attention be focused on intervention programs. © The Author(s) 2013.

    Termites have developed many exocrine glands, generally dedicated to defence or communication. Although a few of these glands occur in all termite species, or represent synapomorphies of larger clades, others are morphological innovations of a single species, or a few related species. Here, we describe the nasus gland, a new gland occurring at the base of the nasus of Angularitermes soldiers. The nasus gland is composed of class 1, 2, and 3 secretory cells, a rare combination that is only shared by the sternal and tergal glands of some termites and cockroaches. The ultrastructural observations suggest that the secretion is produced by class 2 and 3 secretory cells, and released mostly by class 3 cells. The base of the nasus has a rough appearance due to numerous pits bearing openings of canals conducting the secretion from class 3 secretory cells to the exterior. We tentatively assign a defensive function to the nasus gland, although further research is needed to confirm this function. Although the gland is described only from species of Angularitermes, other genera of Nasutitermitinae also present a rough nasus base, suggesting the presence of a similar, possibly homologous, gland.

    This study examines the effects of three types of unwanted sexual experiences in the workplace on the psychological well-being of male and female U.S. Army soldiers, and the mediating or moderating roles of appraisal of sexual harassment, organizational climate, and the sociodemographic profile of victims. A survey was administered to 1,060 male soldiers and 305 female soldiers between May and July, 1995, at three Army posts in the United States. Unwanted sexual experiences were found to be significant predictors of psychological symptoms for male and female soldiers. Certain aspects of organizational climate and appraisal of sexual harassment were also significant predictors of psychological symptoms.

    Full Text Available The purpose of this study was to explore the relationship between job burnout and neuroendocrine indicators in soldiers living in a harsh environment. Three hundred soldiers stationed in the arid desert and 600 in an urban area were recruited. They filled in the Chinese Maslach Burnout Inventory questionnaire. One hundred soldiers were randomly selected from each group to measure their levels of noradrenaline, serotonin, heat shock protein (HSP-70, adrenocorticotropic hormone, and serum cortisol. Job burnout was more common in soldiers from urban areas than those from rural areas. Job burnout was significantly higher among soldiers stationed in the arid desert than those in urban areas. For soldiers in the arid desert, the levels of HSP-70, serum cortisol, and adrenocorticotropic hormone were significantly higher than in soldiers in urban areas. Correlation analyses showed that the degree of job burnout was weakly negatively correlated with the level of HSP-70. Being an only child, HSP-70 levels, cortisol levels, and ACTH levels were independently associated with job burnout in soldiers stationed in the arid desert. A higher level of job burnout in soldiers stationed in arid desert and a corresponding change in neuroendocrine indicators indicated a correlation between occupational stress and neurotransmitters.

    Stress fractures (SF) are common and costly injuries in military personnel. Risk for SF has been shown to vary with race/ethnicity. Previous studies report increased SF risk in white and Hispanic Soldiers compared with black Soldiers. However, these studies did not account for the large ethnic diversity in the US military. We aimed to identify differences in SF risk among racial/ethnic groups within the US Army. A retrospective cohort study was conducted using data from the Total Army Injury and Health Outcomes Database from 2001 until 2011. SF diagnoses were identified from ICD-9 codes. We used Cox-proportional hazard models to calculate time to SF by racial/ethnic group after adjusting for age, education, and body mass index. We performed a sex-stratified analysis to determine whether the ethnic variation in SF risk depends on sex. We identified 21,549 SF cases in 1,299,332 Soldiers (more than 5,228,525 person-years of risk), revealing an overall incidence rate of 4.12 per 1000 person-years (7.47 and 2.05 per 1000 person-years in women and men, respectively). Using non-Hispanic blacks as the referent group, non-Hispanic white women had the highest risk of SF, with a 92% higher risk of SF than non-Hispanic black women (1.92 [1.81-2.03]), followed by American Indian/Native Alaskan women (1.72 [1.44-1.79]), Hispanic women (1.65 [1.53-1.79]), and Asian women (1.32 [1.16-1.49]). Similarly, non-Hispanic white men had the highest risk of SF, with a 59% higher risk of SF than non-Hispanic black men (1.59 [1.50-1.68]), followed by Hispanic men (1.19 [1.10-1.29]). When examining the total US Army population, we found substantial differences in the risk of stress fracture among racial/ethnic groups, with non-Hispanic white Soldiers at greatest risk and Hispanic, American Indian/Native Alaskan, and Asian Soldiers at an intermediate risk. Additional studies are needed to determine the factors underlying these race- and ethnic-related differences in stress fracture risk.

    Musculoskeletal injuries (MSIs) result in the most medical encounters, lost duty days, and permanent disability. Women are at greater risk of injury than men and physical training is the leading cause of injury. The purpose of this study was to investigate the demographic, body composition, fitness, and physical training risk factors for injuries in female Soldiers serving in garrison Army units over the past 12 months. Self-report survey was collected from 625 women. The ankle was the most frequently injured body region, 13%. Running was the activity most often associated with injury, 34%. In univariate analysis lower rank, older age, history of deployment, no unit runs, weekly frequency of personal resistance training, and history of injury were all associated with injury. In multivariate analysis rank, history of injury, weekly frequency of unit runs, and weekly frequency of personal resistance training were the best combination of predictors of injury. Running once or twice a week with the unit protected against MSIs, whereas participating in personal resistance training sessions once or twice a week increased the risk of MSIs. With more emphasis on running and resistance training, the U.S. Army could reduce injuries and save billions of dollars in training and health care costs.

    Searches have been conducted for a broad range of new phenomena by the four experiments ALEPH, DELPHI, L3, and OPAL, at LEP2. Each experiment contributes approximately 150 pb-1 of e+e- annihilation data with a mean sqrt(s) of 205.9 GeV in 2000 to these searches (data prepared for the September 5 LEPC meeting). The statistical procedure for setting limits and evaluating the significance of excesses observed in the data is reviewed. Search results are presented for the Standard Model Higgs boson, the neutral Higgs bosons in the MSSM, charged Higgs bosons, invisibly decaying Higgs bosons produced by Higgs-strahlung, and fermiophobic Higgs bosons. Search results are briefly summarized for gauginos, stops, and staus. The photon recoil spectrum is checked for hints of new physics.

    Suicide attempt (SA) rates in the U.S. Army increased substantially during the wars in Afghanistan and Iraq. This study examined associations of family violence (FV) history with SA risk among soldiers. Using administrative data from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS), we identified person-month records of active duty, Regular Army, enlisted soldiers with medically documented SAs from 2004 to 2009 (n = 9650) and a sample of control person-months (n = 153,528). Logistic regression analyses examined associations of FV with SA, adjusting for socio-demographics, service-related characteristics, and prior mental health diagnosis. Odds of SA were higher in soldiers with a FV history and increased as the number of FV events increased. Soldiers experiencing past-month FV were almost five times as likely to attempt suicide as those with no FV history. Odds of SA were elevated for both perpetrators and those who were exclusively victims. Male perpetrators had higher odds of SA than male victims, whereas female perpetrators and female victims did not differ in SA risk. A discrete-time hazard function indicated that SA risk was highest in the initial months following the first FV event. FV is an important consideration in understanding risk of SA among soldiers.

    Deployment represents a significant potential strain on military families. The impact of postdeployment stresses may be increased if family coping resources are diminished by returning service members' physical injuries, mental health issues, or substance abuse. This article examines the health and mental health correlates of self-reported concerns regarding interpersonal conflict among married soldiers following return from deployment and the likelihood that soldiers acknowledging such concerns are referred to counseling services. Among 20,166 married Army soldiers completing Post-Deployment Health Reassessments, 18% reported having experienced serious interpersonal conflict with their spouse, family members, close friends, or coworkers. Results indicate that interpersonal conflict was more common among those who reported health problems, depression, post-traumatic stress disorder, and alcohol abuse. Among soldiers reporting interpersonal conflict and not already receiving services, 11% were referred to service. Findings support the need to communicate with soldiers and their spouses about the availability of services following return from deployment and to continue efforts to reduce stigma associated with seeking treatment.

    Norway has been contributing military forces to Afghanistan since 2001. The following is an overview of all combat-related injuries and deaths among Norwegian soldiers in the period from 2002 to 2010. All medical records for Norwegian military personnel in Afghanistan in the period to January 2011 were reviewed and those who fell or were injured during combat were identified. The mechanism and anatomical region of the injury were registered and an injury severity score (ISS), revised trauma score (RTS) and probability of survival score were calculated. Deaths were classified according to military trauma terminology and were additionally assessed as either "non-survivable" or "potentially survivable". There were 45 injury incidents with nine deaths among 42 soldiers. The injury mechanism behind seven of the deaths was an improvised explosive device (IED). All injuries resulting in deaths were "non-survivable". Seven soldiers were severely injured. The mechanisms were bullet wounds, IED, splinters from grenades and landmine explosions. Twenty nine incidents involving 28 soldiers resulted in minor injuries. The most frequent mechanism was ricochet or splinter injury from shooting or an exploding grenade. The majority of conflict-related injuries in Afghanistan were due to explosions. The mechanism and anatomical distribution of the injuries was the same among Norwegian soldiers as among allies. The deaths were due to extensive injuries that were non-survivable.

    The purpose of this study was to evaluate the nutrient intake of male and female Soldiers in the 101 st Airborne Division (Air Assault) compared to sports nutrition standards for athletes, and to identify suboptimal eating characteristics that may impair physical performance and jeopardize military readiness. Male and female Soldiers from the 101 st Airborne Division (Air Assault) completed a 24-hour dietary recall and nutrition history questionnaire before anthropometric and body composition measurements were taken. Compared to sports nutrition guidelines, Soldiers of the 101 st under consume carbohydrates (males: 3.9 ± 2.0 vs. 5.0 g/kg, p < 0.001; females: 4.0 ± 2.1 vs. 5.0 g/kg, p = 0.001), male Soldiers eat too much fat (32.4% of kcal vs. <30% of kcal, p = 0.000) and saturated fat (males: 10.5 ± 3.9% of kcal vs. 10.0% of kcal, p = 0.044), and both males and females follow a meal pattern that may not optimize energy availability throughout the day. Eating too much fat and under fueling carbohydrate may negatively impact the adaptations to physical training and compromise overall health. Although Soldiers continue to participate in arduous training programs, future research should be aimed at determining the energy and macronutrient needs to fuel and recover from specific types of military training.

    Prior studies have documented associations of childhood bullying victimization with suicidal behaviors. However, many failed to adjust for concomitant risk factors and none investigated this relationship in military personnel. This study aimed to estimate independent associations of childhood bullying victimization with suicidal behaviors among U.S. Army soldiers. Soldiers reporting for basic training completed a cross-sectional survey assessing mental disorders, suicidal behaviors, and childhood adversities including two types of bullying victimization: (1) Physical Assault/Theft and (2) Bullying Comments/Behaviors. Associations of childhood bullying experiences with suicidal behaviors were estimated using discrete-time survival analysis of person-year data from 30,436 soldiers. Models adjusted for sociodemographic factors, childhood maltreatment by adults, and mental disorders. After comprehensive adjustment for other risk factors, more frequent Physical Assault/Theft by peers during childhood was associated with increased odds of lifetime suicidal ideation (adjusted odds ratio [AOR] = 1.18, 95% CI: 1.11-1.26, P Bullying Comments/Behaviors were associated with increased risk of ideation (AOR = 1.30, 95% CI: 1.26-1.35, P bullying victimization, exposure to the most persistent bullying was associated with two- to fourfold increase in risk for suicidal behaviors. Childhood bullying victimization is associated with lifetime suicidal behaviors among new soldiers. Exposure to Bullying Comments/Behaviors during childhood is associated with progression from suicidal ideation to plan. Improved recognition of these relationships may inform risk mitigation interventions for soldiers. © 2017 Wiley Periodicals, Inc.

    As the use of child soldiers continues to proliferate throughout the world, effective psychosocial interventions must be developed and evaluated. Our research shows that former child soldiers who are provided rehabilitative services and accepted back into their families and communities are able to become productive, responsible and caring adults. In 1988, 39 captured or escaped child soldiers were brought by the Mozambican government to the Lhanguene Rehabilitation Center in Maputo, Mozambique's capital city. Interventions that focused on rehabilitating the children both psychologically and physically were initiated during their 6-month stay at the Lhanguene centre, and reintegration assistance was provided for 2 years thereafter to support their return to families and communities. Our research continued to follow these former child soldiers for 16 years, and focused on their psychological, social and economic functioning. The study included qualitative and quantitative data collection methods to obtain adult well-being outcomes and was also designed to identify interventions that enabled these child soldiers to re-enter civilian life and lead relatively productive lives. Efficacious rehabilitation activities included those that strengthened individuals' coping skills for anticipated trauma and grief, instilled a sense of social responsibility and promoted self-regulation and security (versus survival) seeking behaviour. Activities that supported long term reintegration and self-sufficiency included community acceptance and forgiveness, traditional cleansing and healing rituals, livelihoods and apprenticeships.

    Adult goldenrod soldier beetles, Chauliognathus pensylvanicus, were found infected by the fungus Eryniopsis lampyridarum (Entomophthoromycotina) in Arkansas during September - October (1996, 2001, 2015 and 2016). Living and dead infected beetles were found on flowering frost aster, Symphyotrichum pilosum, common boneset, Eupatorium perfoliatum, and Canada goldenrod, Solidago canadensis. Live and dead beetles (n=446) were collected in 1996 from S. pilosum flowers and held individually in the laboratory for determination of fungal prevalence. Of the beetles collected, 281 (63%) were males and 165 (37%) were females. A total of 90 beetles were infected with E. lampyridarum, an overall prevalence of 20.2%. Prevalence in males was 19.6% (n=55 infected/281 males total) and prevalence in females was 21.2% (n=35 infected /165 females total). Conidia were produced from 57% of the infected beetles, 23% of the infected beetles produced resting spores, and 20% contained the hyphal body stage. Infected beetles produced either conidia or resting spores but never both in the same host. Post-mortem morphological changes in the hosts due to E. lampyridarum were observed periodically for 24h. Shortly before death, by unknown mechanisms, dying infected beetles tightly clamped their mandibles into flower heads and ca. 15-22h later (between 2400 and 0700h) the fungus caused dead beetles to raise their elytra and expand their metathoracic wings.

The correlation of personal values with symptoms, however, has not yet been examined within a military context. Method: Schwartz's Portrait Values Questionnaire (PVQ, the Posttraumatic Stress Diagnostic Scale (PDS, and the 11-item version of the Resilience Scale (RS-11 were completed by 117 soldiers of the German Armed Forces who had recently been deployed to Afghanistan (n=40 undergoing initial psychiatric treatment, n=77 untreated. Results: Logistic regression showed that the value types of hedonism (−, power (−, tradition (+, and universalism (+ were significantly correlated with the probability and severity of PTSD and whether the participant was in treatment or not. The effects were partially mediated by the RS-11 scale values. Conclusions: Value types seem to be associated with psychiatric symptoms in soldiers after deployment. These results could contribute to the further development of therapeutic approaches.

    Soldiers are at increased risk of developing mental health disorders after military deployment. The impact of personal values on psychological symptomatology based on an empirical working model has not yet been studied in a military environment. 117 German Armed Forces soldiers completed the Portrait-Values-Questionnaire (PVQ), the Patient-Health-Questionnaire (PHQ) and the Resilience-Scale (RS-11) after their deployment to Afghanistan. In the regression analyses the values hedonism, benevolence, tradition, self-direction and universalism had a differential significant impact on depression, anxiety and somatoform symptoms of the PHQ. The RS-11 sum scale values were negatively correlated with symptomatology. Personal values and resilience seem to be associated with psychological symptomatology in soldiers after military deployment. The results can contribute to the further development of both preventive and therapeutic approaches. © Georg Thieme Verlag KG Stuttgart · New York.

    Bioenergy has become attractive as alternatives of gradually exhausted fossil fuel. Obtaining high grade bioenergy from lignocellulose is attractive that can gradually meet the demand. This study reported biogas and biodiesel were produced from corncob by a two-step bioprocess, biogas was produced from corncob by anaerobic fermentation, then biogas residue was converted by black soldier fly larvae, and then biodiesel was produced from larvae grease. 86.70 L biogas was obtained from 400 g corncob with the accumulation of biogas yield of 220.71 mL/g VS(added) by anaerobic digestion. Besides, 3.17 g of biodiesel was produced from grease after inoculating black soldier fly larvae into 400 g biogas residue. Meanwhile, the results showed that the addition of black soldier fly larvae could be effective for the degradation of lignocellulose and the accumulation of grease. Copyright © 2015 Elsevier Ltd.

    Soldiers are at risk for acute and chronic pain due to the mental and physical challenges of military duties and ongoing training for force readiness. With the burden of pain on any individual attributable across pain sources, a broad perspective that goes beyond prior characterizations of pain is important. We aim to further the understanding of pain's effects among non-deployed active duty soldiers and the Military Health System (MHS), by describing prevalence of 10 painful conditions, reported pain levels, duration of pain and impact of pain on military duty limitations. Data are from the MHS Data Repository including outpatient MHS direct care encounters, claims for outpatient purchased care from civilian providers, and vital records, for all soldiers continuously enrolled in TRICARE and not deployed in FY 2012. Ten pain-related diagnostic categories were conceptually derived for this analysis and identified using ICD-9-CM diagnostic codes. We report the FY 2012 prevalence at the soldier-level (N = 297,120) for each pain category as a primary diagnosis, as well as in any diagnostic position, and at the soldier-level for reported pain level, duration, and military duty limitations. Institutional Review Board approval was obtained prior to analyses. Overall, 63% of soldiers had at least one pain diagnosis and 59% had a primary pain diagnosis during FY 2012. Back and neck pain (22%), non-traumatic joint disorders (28%), and other musculoskeletal pain (30%) were the most frequent categories for primary diagnosis. Nearly two-thirds of soldiers had a primary pain diagnosis in more than one category, and 23% in four or more categories. Moderate or severe pain levels were reported at least once during the year by 55% of soldiers who had a primary pain diagnosis. In the subsample of soldiers with primary pain in the first quarter, duration and chronicity of pain diagnoses varied by pain category: the back and neck pain category was the most common for both persistent

    Preventing involuntary conscription and voluntary recruitment of youth into armed groups are global human rights priorities. Pathways for self-reported voluntary recruitment and the impact of voluntary recruitment on mental health have received limited attention. The objective of this study was to identify risk factors for voluntarily joining armed groups, as well as the association of conscription status and mental health. In Nepal, interviews were conducted with 258 former child soldiers who participated in a communist (Maoist) revolution. Eighty percent of child soldiers joined 'voluntarily'. Girls were 2.07 times as likely to join voluntarily (95% CI, 1.03-4.16, p =0.04). Among girls, 51% reported joining voluntarily because of personal connections to people who were members of the armed group, compared to 22% of boys. Other reasons included escaping difficult life situations (36%), inability to achieve other goals in life (28%), and an appealing philosophy of the armed group (32%). Poor economic conditions were more frequently endorsed among boys (22%) than girls (10%). Voluntary conscription was associated with decreased risk for PTSD among boys but not for girls. Interventions to prevent voluntary association with armed groups could benefit from attending to difficulties in daily life, identifying non-violent paths to achieve life goals, and challenging the political philosophy of armed groups. Among boys, addressing economic risk factors may prevent recruitment, and prevention efforts for girls will need to address personal connections to armed groups, as it has important implications for preventing recruitment through new methods, such as social media.

    The rate of permanent disability retirement in U.S. Army soldiers and the prevalence of combat-related disabilities have significantly increased over time. Prior research on risk factors associated with disability retirement included soldiers retired prior to conflicts in Iraq and Afghanistan. To identify risk factors for disability discharge among soldiers enlisted in the U.S. Army during military operations in Iraq and Afghanistan. In this case-control study, cases included active duty soldiers evaluated for disability discharge. Controls, randomly selected from soldiers with no history of disability evaluation, were matched to cases based on enlistment year and sex. Conditional logistic regression models calculated odds of disability discharge. Attributable fractions estimated burden of disability for specific pre-existing condition categories. Poisson regression models compared risk of disability discharge related to common disability types by deployment and combat status. Characteristics at military enlistment with increased odds of disability discharge included a pre-existing condition, increased age or body mass index, white race, and being divorced. Musculoskeletal conditions and overweight contributed the largest proportion of disabilities. Deployment was protective against disability discharge or receiving a musculoskeletal-related disability, but significantly increased the risk of disability related to a psychiatric or neurological condition. Soldiers with a pre-existing condition at enlistment, particularly a musculoskeletal condition, had increased odds of disability discharge. Risk of disability was dependent on condition category when stratified by deployment and combat status. Additional research examining conditions during pre-disability hospitalizations could provide insight on specific conditions that commonly lead to disability discharge. Copyright © 2016 Elsevier Inc.

    The CERN p bar p Collider has been the first accelerator to operate in a completely new energy domain, reaching center-of-mass energies an order of magnitude larger than those previously available with the intersecting Storage Rings (ISR) at CERN, or with the Positron-Electron Tandem Ring Accelerator (PETRA) at DESY and the Positron-Electron Project (PEP) at SLAC. Naturally there has been great interest in the searches for new physics in this virgin territory. Theorists have approached these searches from either or both of two rival points of view. Either they have had an a priori prejudice as to what new physics should be searched for, and what its signatures should be, or they have tried to interpret a posteriori some experimental observations. The basic building-blocks of new physics in the 100 GeV energy domain are jets j, charged leptons l, photons γ, and missing transverse energy E T . Therefore searches have been conducted in channels which are combinations of these elements. It also shows some of the main a priori theoretical prejudices which can be explored in each of these channels. The layout of the rest of this paper is as follows. There are sections discussing each of the major prejudices: the Standard Model supersymmetry; extra gauge degrees of freedom; composite models; and other possibilities. Each of these sections contains a description of the motivations and characteristics of the new physics to be searched for, followed by a review of the searches made up to now at the CERN p bar p Collider. Finally, it summarizes the lessons to be learnt so far from searches for new physics at the CERN p bar p Collider, and previews some of the prospects for the next rounds of collider searches at CERN and FNAL

    Addressing the medical concerns of veterans in both civilian health care systems and the Veterans Affairs (VA) health care system, where staff are familiar with issues of military reintegration, remains difficult but is increasingly important. In 2013, the authors developed and implemented a faculty development workshop for practicing clinicians using the documentary Where Soldiers Come From. The workshop included topics on unconscious bias, the service member trajectory, health care disparities, and strategies for overcoming barriers to treating veterans with posttraumatic stress disorder and traumatic brain injury. The workshop engaged faculty in the following active-learning techniques: images in education; trigger video; critical thinking and reflective writing; think-pair-share; and large-group discussion. The workshop has been conducted at three locations with 46 health care professionals. Thirty-one of 37 (84%) participants who completed the workshop evaluation were VA employees. The evaluation results show 25/32 (78.1%) participants indicated the workshop activities changed their knowledge, attitudes, and/or skills; 22/34 (64.7%) stated they had a better understanding of how to develop a care plan for veterans; and 27/34 (79.4%) stated they gained a better understanding of how to prepare for issues around returning veterans. To address the issue of veteran-centered care education more broadly, the authors have developed a massive open online course for health professionals, using most of the content from this workshop, which will be offered in spring 2016. Another important next step will be to deliver this workshop to and collect evaluation data from non-VA providers.

    Full Text Available The article approaches the iconography of two etchings with Croatian subject matter made by the Bolognese etcher Giuseppe Maria Mitelli in 1684. In the focus is the etching Great Bravery of Croatian soldier (Gran prodezza di soldato croatto. The author concludes, interpreting the explanatory text below the etching, that it depicts an event of the so-called Great Turkish War (1683-1699. The depicted hero belonged to the Croatian Regiment commanded by general James Leslie, and the depicted heroic act occurred, in all probability, during the battle of Virovitica in 1684. Also, the author points out to a model for Mitelli's etching as well as to the literary image of the simultaneous decapitation of both a horseman and a horse in the Croatian literature. In the same year, Mitelli also made the portrait of the Zagreb bishop and the politician Martin Borković. The existence of both etchings is associated with the Illyrian-Hungarian College in Bologna, governed by the Zagreb cathedral Chapter. L'articolo indaga l'iconografia di due incisioni con soggetto croato realizzate dall'incisore bolognese Giuseppe Maria Mitelli nel 1684. Il focus del saggio è l'incisione Gran prodezza di soldato croatto. Interpretando il testo esplicativo sotto l'acquaforte, l'autore ritiene che essa raffiguri un evento della cosiddetta Grande Guerra Turca (1683-1699. L'eroe raffigurato apparteneva al reggimento croato comandato dal generale James Leslie e l'atto eroico raffigurato avvenne, con ogni probabilità, durante la battaglia di Virovitica nel 1684. L'autore individua inoltre un modello per l'incisione di Mitelli e un riferimento a una fonte nella letteratura croata ove compare la decapitazione simultanea di un cavaliere e di un cavallo. Nello stesso anno Mitelli fece anche il ritratto del vescovo di Zagabria e del politico Martin Borković. L'esistenza di entrambe le acqueforti è associata al Collegio illirico-ungarico di Bologna, governato dal Capitolo della

    Division of labour in eusocial insects is characterized by efficient communication systems based on pheromones. Among such insects, termites have evolved specialized sterile defenders, called soldiers. Because they are incapable of feeding themselves, it has been suggested that soldiers are sustained by workers and emit the pheromone arresting workers. However, such a soldier pheromone has not been identified in any termite species, and the details of the soldier-worker interaction remain to be explored. Here, we identified a soldier-specific volatile sesquiterpene as a worker arrestant, which also acts as a primer pheromone regulating soldier differentiation and fungistatic agent in a termite Reticulitermes speratus Chemical analyses revealed that (-)- β -elemene is the major component of soldier extract, and its authentic standard exhibited arrestant activity to workers and inhibited the differentiation from workers to soldiers. This compound also showed fungistatic activity against entomopathogenic fungi. These suggest that (-)- β -elemene secreted by soldiers acts not only as a worker arrestant but also as one component of inhibitory primer pheromone and an anti-pathogenic agent. Our study provides novel evidence supporting the multi-functionality of termite soldier pheromone and provides new insights into the role of soldiers and the evolutionary mechanisms of pheromone compounds. © 2017 The Author(s).

    Full Text Available This study aims to reveal the process of soldier's mental development in Iskandar Muda Military Command, both seen from the selection process to be soldier in educational institutions as well as in the unit assignment. This research is expected to find the development pattern in accordance with the challenging tasks for the National Military (TNI ahead. By using a qualitative approach, this research has achieved several findings: 1 in the selection process, a soldier was just demanded to fundamentally have religious understanding without a standard point for depth understanding of religion, 2 in the first stage of education, the subject matter of religion only a broad outline of religious teachings, 3 religious activities is not part of military trainings curriculum, but it is merely education administrators’ policy, 4 the soldiers in unit deemed to have knowledge of the religion and an unwavering faith. Despite the fact that soldiers’ religious knowledge is still very low, while the faith is generally used as the symbolic emphasis that is less discussed. As a result, it is feared that mentality weakness when facing a tough task, both faced with the sophistication of tools, strategies and mental demands in modern warfare in the future.

    Full Text Available Abstract Psychotrauma occurs as a result to a traumatic event, which may involve witnessing someone's actual death or personally experiencing serious physical injury, assault, rape and sexual abuse, being held as a hostage, or a threat to physical or psychological integrity. Post-traumatic stress disorder (PTSD is an anxiety disorder and was defined in the past as railway spine, traumatic war neurosis, stress syndrome, shell shock, battle fatigue, combat fatigue, or post-traumatic stress syndrome (PTSS. If untreated, post-traumatic stress disorder can impair relationships of those affected and strain their families and society. Deployed soldiers are especially at a high risk to be affected by PTSD but often receive inadequate treatment. Reviews to date have focused only on a single type of treatment or groups of soldiers from only one country. The aim of the current review was to evaluate characteristics of therapeutic methods used internationally to treat male soldiers' PTSD after peacekeeping operations in South Eastern Europe and the Gulf wars. This systematic literature review returned results pertaining to the symptoms, diagnosis, timing and effectiveness of treatment. Sample groups and controls were relatively small and, therefore, the results lack generalizability. Further research is needed to understand the influence and unique psychological requirements of each specific military operation on the internationally deployed soldiers.

    In addition to military radios, modern warfighters carry cell phones, GPS devices, computers, and night-vision aids, all of which require electrical cables and connectors for data and power transmission. Currently each electrical device operates via independent cables using conventional cable and connector technology. Conventional cables are stiff and difficult to integrate into a soldier-worn garment. Conventional connectors are tall and heavy, as they were designed to ensure secure connections to bulkhead-type panels, and being tall, represent significant snag-hazards in soldier-worn applications. Physical Optics Corporation has designed a new, lightweight and low-profile electrical connector that is more suitable for body-worn applications and operates much like a standard garment snap. When these connectors are mated, the combined height is <0.3 in. - a significant reduction from the 2.5 in. average height of conventional connectors. Electrical connections can be made with one hand (gloved or bare) and blindly (without looking). Furthermore, POC's connectors are integrated into systems that distribute data or power from a central location on the soldier's vest, reducing the length and weight of the cables necessary to interconnect various mission-critical electronic systems. The result is a lightweight power/data distribution system offering significant advantages over conventional electrical connectors in soldier-worn applications.

    Characterize the distribution of foot-strike (FS) patterns in U.S. Army Soldiers and determine if FS patterns are related to self-reported running injuries and performance. 341 male Soldiers from a U.S. Army Combined Arms Battalion ran at their training pace for 100 meters, and FSs were recorded in the sagittal plane. Participants also completed a survey related to training habits, injury history, and run times. Two researchers classified FS patterns as heel strike (HS) or nonheel strike (NHS, combination of midfoot strike and forefoot strike patterns). Two clinicians classified the musculoskeletal injuries as acute or overuse. The relationship of FS type with two-mile run time and running-related injury was analyzed (p ≤ 0.05). The Soldiers predominately landed with an HS (87%) and only 13% were characterized as NHS. Running-related injury was similar between HS (50.3%) and NHS (55.6%) patterns (p = 0.51). There was no difference (p = 0.14) between overuse injury rates between an HS pattern (31.8%) and an NHS pattern (31.0%). Two-mile run times were also similar, with both groups averaging 14:48 minutes. Soldiers were mostly heel strikers (87%) in this U.S. Army Combined Arms Battalion. Neither FS pattern was advantageous for increased performance or decreased incidence of running-related injury. Reprint & Copyright © 2015 Association of Military Surgeons of the U.S.

    The article presents the results of a research study into the reasons for medical evacuations of Polish military personnel taking part in the International Security Assistance Force (ISAF) operation in Afghanistan from 2007 to 2013. The authors have analysed medical records of 485 soldiers who were medically evacuated out of a combat zone in Afghanistan for battle injuries, non-battle injuries and diseases. Each medically evacuated Polish soldier was subjected to statistical analysis. The study population comprised 25,974 soldiers assigned to the Polish Military Contingent Afghanistan in the given period. From 2007 to 2013, 1.9% of the Polish military personnel (n = 485) participating in the ISAF operation in Afghanistan were evacuated for medical reasons before the scheduled termination of their contract. 40.6% of all medical evacuations were due to battle injuries, 32.4% due to non-battle injuries, and 27.0% due to diseases. ISAF is an example of a combat operation, in which battle injuries remain the leading health problem in mission participants. 3 of 4 Polish soldiers who were medically evacuated from Afghanistan were no longer fit for military service in the area of operations due to the traumas they had suffered.

    New-onset asthma rates are higher among US soldiers deployed to Iraq/Afghanistan than stateside, but overall respiratory symptom and spirometry rates among soldiers returning from Iraq/Afghanistan have not yet been addressed. We determined these rates in soldiers deployed to Iraq/Afghanistan versus troops stationed elsewhere. Retrospective review of active-duty soldiers (2004 to 2010) registered at Veterans Affairs Medical Center, Northport, New York, with Long Island/New York City zip codes. Subjects were examined by physicians or physicians' assistants. We counted number of spirometries, which required respiratory symptoms, and the provider was required to submit a diagnosis as part of the request process. Twenty-five percent of 7151 troops went to Iraq/Afghanistan (n = 1816) and 75% went elsewhere (n = 5335), with more smokers in the Iraq/Afghanistan group (16.1% vs 3.3%). Rates of symptoms and spirometry were 14.5% and 1.8%, for Iraq/Afghanistan, versus troops deployed elsewhere, respectively (P Afghanistan war lung injury is common and rates of symptoms leading to a diagnosis requiring spirometry are high.

    Using hand sanitizers can reduce bacterial contamination and is an efficient and inexpensive method of preventing infections. The purpose of this study was to explore the behavioral intention (low and absolute), attitudes, subjective norms, and perceived behavioral control of hand sanitizer use among US Army soldiers. A questionnaire was developed following an expert panel (N = 5) review and 2 pilot studies (N = 35) to ensure questionnaire validity and clarity. Surveys were distributed among nontrainee soldiers during lunch periods. A total of 201 surveys were collected. Results indicated that attitudes, subjective norms, and perceived behavioral controls explained 64% of the variance in behavioral intention. Attitude remained the strongest predictor of behavior (β = 0.70, P hand sanitizers hold significantly different behavioral and normative beliefs than low intenders. Other soldiers create negative social pressure about using hand sanitizers, indicating that if other soldiers use hand sanitizers, they will refuse to do so. Intervention to ensure use of hand sanitizer should focus on strengthening behavioral and normative beliefs among low intenders. This should increase the overall well being of the military.

    Full Text Available Authors examine the question of the types, scale, efficiency of public aid and social support of soldiers' families in Yenisei province during the First World War. Particular attention is paid to the activities of cities and urban guardianship organizations that have paid to families of the mobilized amount exceeding the amount of state benefits. It is shown that in the rural guardianship organizations did not have more money. They failed to organize labor help with the agricultural work. Soldiers' families reduced tillage, many of them wanted to move to the provincial center. Siberian city were not a major commercial and industrial centers, their budgets have been modest. Siberia had no zemstvo institutions, therefore, the city suffered heavy costs for the solution of many other problems caused by wartime (the organization of assistance to refugees and the injured, the fight against the high cost and lack of, the development of cooperatives, and others, they were making regular payments for all-Russian charitable societies. The flow of donations to urban guardianship and charitable organizations has decreased dramatically in 1916, and the number in need has increased significantly, the municipal government began to curtail payments to soldiers' families. The discontent of the soldiers' wives resulted in the pogroms of malls and attacks against members of municipal self-government bodies of Minusinsk, Krasnoyarsk, Kansk in 1916–1917.

    With increasing necessity for intuitive Soldier-robot communication in military operations and advancements in interactive technologies, autonomous robots have transitioned from assistance tools to functional and operational teammates able to service an array of military operations. Despite improvements in gesture and speech recognition technologies, their effectiveness in supporting Soldier-robot communication is still uncertain. The purpose of the present study was to evaluate the performance of gesture and speech interface technologies to facilitate Soldier-robot communication during a spatial-navigation task with an autonomous robot. Gesture and speech semantically based spatial-navigation commands leveraged existing lexicons for visual and verbal communication from the U.S Army field manual for visual signaling and a previously established Squad Level Vocabulary (SLV). Speech commands were recorded by a Lapel microphone and Microsoft Kinect, and classified by commercial off-the-shelf automatic speech recognition (ASR) software. Visual signals were captured and classified using a custom wireless gesture glove and software. Participants in the experiment commanded a robot to complete a simulated ISR mission in a scaled down urban scenario by delivering a sequence of gesture and speech commands, both individually and simultaneously, to the robot. Performance and reliability of gesture and speech hardware interfaces and recognition tools were analyzed and reported. Analysis of experimental results demonstrated the employed gesture technology has significant potential for enabling bidirectional Soldier-robot team dialogue based on the high classification accuracy and minimal training required to perform gesture commands.

    Full Text Available The present study aimed to evaluate posttraumatic stress symptoms, psychological distress, and emotional and behavioral problems in former Ugandan child soldiers in comparison with civilian children living in the same conflict setting. Participants included 133 former child soldiers and 101 never-abducted children in northern Uganda, who were interviewed about exposure to traumatic war-related experiences, posttraumatic stress symptoms, psychological distress, and emotional and behavioral problems. Results indicated that former child soldiers had experienced significantly more war-related traumatic events than nonabducted children, with 39.3% of girls having been forced to engage in sexual contact. Total scores on measures of PTSD symptoms, psychological distress, and emotional and behavioral problems were significantly higher among child soldiers compared to their never-abducted peers. Girls reported significantly more emotional and behavioral difficulties than boys. In never-abducted children, more mental health problems were associated with experiencing physical harm, witnessing the killings of other people, and being forced to engage in sexual contact.

    Full Text Available The aim of the study was to investigate the correlation between motor ability of coordination and personality traits of Slovenian soldiers. The subject sample consisted of 94 soldiers in a battle unit of Slovenian Armed Forces (SAF who were serving in the first brigade (age 26,5 ± 3,4 years. Motor ability of coordination was assessed with two motor tasks (polygon bac- kwards and figure 8 duck test. The structure of personality traits was measured with a FPI (Freiburg Personality Inventory included 114 items and measured 9 personality traits of order I (neuroticism, impulsivity, depression, irritability, sociability, calmness, dominance, suppression, sincerity and 3 personality traits of order II (extroversion, emotional istability, masculinity. The correlation between coordination and personality traits was estimated by the Pearson’s correlation coefficient. The results show that soldiers who did worse in motor test polygon backwards were more neurotic, suppressed, and impulsive. They also tend to be more sociable. The correlation between second test of coordination shows that better soldiers in this test are more extrovert or less introvert.

  10. [The disease and treatment of the frontline soldiers in Han dynasty].

    2015-04-01

    This paper purports to identify and analyze the medical information of the frontline soldiers in the Northwest borderland provinces of Han Dynasty, especially Juyan and Dunhuang region, through an heuristic reading of the Juyan Bamboo Slips and the Dunhuang Bamboo Slips of the Han Dynasty. My findings are as follows. The most frequent disease found in the bamboo slips was the external injury. The injury of the frontline soldiers mainly occurred from the quarrels among armed soldiers using weapons. The bamboo slips also demonstrate that the quarrels usually arose due to the fierce tension caused by the frontier line service such as heavy guard activity and labour duty. Undernourishment and chronic stress the soldiers suffered might be another reasons. The second most common disease harassing the soldiers was exogenous febrile disease. In most cases reviewed in this paper, the exogenous febrile disease was usually concurrent with complex symptoms such as chills, fever, headache, etc. The bamboo slips show that the exogenous febrile disease was related to the harsh climate of the Northwest provinces, featuring extremely dry weather and the large magnitude of diurnal temperature fluctuations. In addition, the annual temperature range in the Northwest province was huge, fluctuating between very cold and dry winter and very hot and dry summer. The third most common disease this study identified was the disorder of the digestive system and respiratory system. However, these two types of disease were virtually indistinguishable in the bamboo slips, because the ancient Chinese chroniclers did not distinguish them, usually dubbing both diseases simply 'abdominal pain.' It should be mentioned that a few slips mention contagious disease such as dysentery and dermatolosis, and sudden death, as well. Overall, the bamboo slips demonstrate extremely poor status of the soldiers' heath condition and poor medical environment surrounding the soldiers stationing in the Northwest

    2007-04-01

    As the Army's Future Combat Systems (FCS) introduce emerging technologies and new force structures to the battlefield, soldiers will increasingly face new challenges in workload management. The next generation warfighter will be responsible for effectively managing robotic assets in addition to performing other missions. Studies of future battlefield operational scenarios involving the use of automation, including the specification of existing and proposed technologies, will provide significant insight into potential problem areas regarding soldier workload. The US Army Tank Automotive Research, Development, and Engineering Center (TARDEC) is currently executing an Army technology objective program to analyze and evaluate the effect of automated technologies and their associated control devices with respect to soldier workload. The Human-Robotic Interface (HRI) Intelligent Systems Behavior Simulator (ISBS) is a human performance measurement simulation system that allows modelers to develop constructive simulations of military scenarios with various deployments of interface technologies in order to evaluate operator effectiveness. One such interface is TARDEC's Scalable Soldier-Machine Interface (SMI). The scalable SMI provides a configurable machine interface application that is capable of adapting to several hardware platforms by recognizing the physical space limitations of the display device. This paper describes the integration of the ISBS and Scalable SMI applications, which will ultimately benefit both systems. The ISBS will be able to use the Scalable SMI to visualize the behaviors of virtual soldiers performing HRI tasks, such as route planning, and the scalable SMI will benefit from stimuli provided by the ISBS simulation environment. The paper describes the background of each system and details of the system integration approach.

    2015-07-01

    Full Text Available Soldiering is defined as engaging behaviourally or cognitively into non-work-related activities during working hours with no intention of harming the employer, co-workers, and/or clients. The present study will investigate this phenomenon using the Job-Demands Resources Model. The proposed model will consider the influence of job demands and resources on soldiering, as well as the relationship of soldiering with employee wellbeing and performance. The data, collected via online questionnaires across seven European countries, will be analysed using structural equation modelling in order to explore the goodness-of-fit of the proposed model as well as its potential cross cultural variations.

    The conflicts in Afghanistan and Iraq have greatly increased the number of veterans returning home with combat exposure, reintegration issues, and psychiatric symptoms. National Guard soldiers face additional challenges. Unlike active duty soldiers, they do not return to military installations with access to military health services or peers. The authors describe the formation and activities of a partnership among two large state universities in Michigan and the Michigan Army National Guard, established to assess and develop programming to meet the needs of returning soldiers. The process of forming the partnership and the challenges, opportunities, and benefits arising from it are described.

    Searching the Web for documents using information retrieval systems plays an important part in clinicians' practice of evidence-based medicine. While much research focuses on the design of methods to retrieve documents, there has been little examination of the way different search engine capabilities influence clinician search behaviors. Previous studies have shown that use of task-based search engines allows for faster searches with no loss of decision accuracy compared with resource-based engines. We hypothesized that changes in search behaviors may explain these differences. In all, 75 clinicians (44 doctors and 31 clinical nurse consultants) were randomized to use either a resource-based or a task-based version of a clinical information retrieval system to answer questions about 8 clinical scenarios in a controlled setting in a university computer laboratory. Clinicians using the resource-based system could select 1 of 6 resources, such as PubMed; clinicians using the task-based system could select 1 of 6 clinical tasks, such as diagnosis. Clinicians in both systems could reformulate search queries. System logs unobtrusively capturing clinicians' interactions with the systems were coded and analyzed for clinicians' search actions and query reformulation strategies. The most frequent search action of clinicians using the resource-based system was to explore a new resource with the same query, that is, these clinicians exhibited a "breadth-first" search behaviour. Of 1398 search actions, clinicians using the resource-based system conducted 401 (28.7%, 95% confidence interval [CI] 26.37-31.11) in this way. In contrast, the majority of clinicians using the task-based system exhibited a "depth-first" search behavior in which they reformulated query keywords while keeping to the same task profiles. Of 585 search actions conducted by clinicians using the task-based system, 379 (64.8%, 95% CI 60.83-68.55) were conducted in this way. This study provides evidence that

    Full Text Available Introduction. Since 2013, European soldiers have been deployed on the European Union Training Mission (EUTM in Mali. From the beginning, diarrhea has been among the most “urgent” concerns. Diarrhea surveillance based on deployable real-time PCR equipment was conducted between December 2013 and August 2014. Material and Methods. In total, 53 stool samples were obtained from 51 soldiers with acute diarrhea. Multiplex PCR panels comprised enteroinvasive bacteria, diarrhea-associated Escherichia coli (EPEC, ETEC, EAEC, and EIEC, enteropathogenic viruses, and protozoa. Noroviruses were characterized by sequencing. Cultural screening for Enterobacteriaceae with extended-spectrum beta-lactamases (ESBL with subsequent repetitive sequence-based PCR (rep-PCR typing was performed. Clinical information was assessed. Results. Positive PCR results for diarrhea-associated pathogens were detected in 43/53 samples, comprising EPEC (n=21, ETEC (n=19, EAEC (n=15, Norovirus (n=10, Shigella spp./EIEC (n=6, Cryptosporidium parvum (n=3, Giardia duodenalis (n=2, Salmonella spp. (n=1, Astrovirus (n=1, Rotavirus (n=1, and Sapovirus (n=1. ESBL-positive Enterobacteriaceae were grown from 13 out of 48 samples. Simultaneous infections with several enteropathogenic agents were observed in 23 instances. Symptoms were mild to moderate. There were hints of autochthonous transmission. Conclusions. Multiplex real-time PCR proved to be suitable for diarrhea surveillance on deployment. Etiological attribution is challenging in cases of detection of multiple pathogens.

    Conduct disorder (CD) is a frequently occurring psychiatric disorder characterized by a persistent pattern of aggressive and non-aggressive rule breaking antisocial behaviours that lead to considerable burden for the patients themselves, their family and society. This review paper updates diagnostic and therapeutic approaches to CD in the light of the forthcoming DSM-5 definition. The diagnostic criteria for CD will remain unchanged in DSM-5, but the introduction of a specifier of CD with a callous-unemotional (CU) presentation is new. Linked to this, we discuss the pros and cons of various other ways to subtype aggression/CD symptoms. Existing guidelines for CD are, with few exceptions, already of a relatively older date and emphasize that clinical assessment should be systematic and comprehensive and based on a multi-informant approach. Non-medical psychosocial interventions are recommended as the first option for the treatment of CD. There is a role for medication in the treatment of comorbid syndromes and/or in case of insufficient response to psychosocial interventions and severe and dangerous aggressive and violent behaviours.

    Foulis, SA, Redmond, JE, Frykman, PN, Warr, BJ, Zambraski, EJ, and Sharp, MA. U.S. Army physical demands study: reliability of simulations of physically demanding tasks performed by combat arms soldiers. J Strength Cond Res 31(12): 3245-3252, 2017-Recently, the U.S. Army has mandated that soldiers must successfully complete the physically demanding tasks of their job to graduate from their Initial Military Training. Evaluating individual soldiers in the field is difficult; however, simulations of these tasks may aid in the assessment of soldiers' abilities. The purpose of this study was to determine the reliability of simulated physical soldiering tasks relevant to combat arms soldiers. Three cohorts of ∼50 soldiers repeated a subset of 8 simulated tasks 4 times over 2 weeks. Simulations included: sandbag carry, casualty drag, and casualty evacuation from a vehicle turret, move under direct fire, stow ammunition on a tank, load the main gun of a tank, transferring ammunition with a field artillery supply vehicle, and a 4-mile foot march. Reliability was assessed using intraclass correlation coefficients (ICCs), standard errors of measurement (SEMs), and 95% limits of agreement. Performance of the casualty drag and foot march did not improve across trials (p > 0.05), whereas improvements, suggestive of learning effects, were observed on the remaining 6 tasks (p ≤ 0.05). The ICCs ranged from 0.76 to 0.96, and the SEMs ranged from 3 to 16% of the mean. These 8 simulated tasks show high reliability. Given proper practice, they are suitable for evaluating the ability of Combat Arms Soldiers to complete the physical requirements of their jobs.

    This paper describes the development of a wearable exoskeleton system for the lower extremities of infantry soldiers and proposes appropriate design criteria based on existing case studies. Because infantry soldiers carry a variety of equipment, the interference with existing equipment and additional burden of the exoskeleton support system should be minimized. Recent studies have shown that a user only needs to be supported in the gravitational direction when walking on flat terrain; however...

  6. Modulation of nutrient composition of black soldier fly (Hermetia illucens) larvae by feeding seaweed-enriched media.

    Black soldier fly (Hermetia illucens) larvae are a promising source of protein and lipid for animal feeds. The nutritional composition of the BSF larvae depend partly on the composition of the feeding medium. The BSF lipid profile in part mimics the feeding media lipid profile, and micronutrients, like minerals and vitamins, can readily accumulate in black soldier fly larvae. However, investigative studies on bioconversion and accumulation of nutrients from media to black soldier fly larvae are scarce. Here we show that inclusion of the brown algae Ascophyllum nodosum in the substrate for black soldier fly larvae can introduce valuable nutrients, commonly associated with the marine environment, into the larvae. The omega-3 fatty acid eicosapentaenoic acid (20:5n-3), iodine and vitamin E concentrations increased in the larvae when more seaweed was included in the diet. When the feeding media consisted of more than 50% seaweed, the larvae experienced poorer growth, lower nutrient retention and lower lipid levels, compared to a pure plant based feeding medium. Our results confirm the plasticity of the nutritional make-up of black soldier fly larvae, allowing it to accumulate both lipid- and water-soluble compounds. A broader understanding of the effect of the composition of the feeding media on the larvae composition can help to tailor black soldier fly larvae into a nutrient profile more suited for specific feed or food purposes.

    This article explores the role of caregivers in the reintegration of former child soldiers from Sierra Leone. Using data on 282 youth and their respective caregivers, our aim is to focus on the caregiver–child relationship after reintegration. We investigate the extent to which caregivers know about child soldiers' experiences of direct and indirect violence, as well as involvement in war activities. We further examine variables that might shape the degree of caregiver knowledge of child's war experiences. Finally, we examine if caregiver knowledge of war experiences is associated with child's psychosocial outcomes. Findings highlight the importance of developing thoughtful programs that consider the needs of the child in the context of the family and caregivers with whom he or she is reunified. PMID:29249893

    Paleoparasitological investigations revealed the presence of intestinal helminths in samples taken from the abdominal cavities of two German soldiers, recovered in the First World War site named "Kilianstollen" in Carspach, France. Eggs from roundworm, whipworm, tapeworm and capillariids were identified. The morphological and morphometrical comparison, followed by statistical analyses, showed that the Carspach capillariid eggs are similar to rodent parasites. Poor sanitary conditions in the trenches, the lack of knowledge of parasites, and the widespread presence of commensal animals, can explain the occurrence of such parasites in human intestines. This study is the second dealing with 20th century human samples. It confirms the presence of intestinal worms in First World War German soldiers. In this case study, the application of statistics to precise measurements facilitated the diagnosis of ancient helminth eggs and completed the microscopic approach.

    Full Text Available The study has aimed to evaluate results of reproductive health training in the First army as a part the Reproductive Health Program of Turkish Armed Forces (TAF. Hard copies of training results from the a sample of 9 reproductive health classrooms between November 2006 and February 2007 have been collected and analyzed after entering in a SPSS file. A Pre-test and a post-test included the same 25 questions on RH issues were given to the soldiers. Total mean scores and scores for 5 modules of Sexual Health, Sexually Transmitted Infections (STIs, Contraceptives, Safe Motherhood, and Gender, were estimated. By deciding 60 as cutting point, achievement of soldiers was also evaluated. Total Pre and posttest mean scores were compared between groups according to the achievement, hometown, and region of residency, educational level, and marital status. Furthermore, Relative efficiency, Efficiency attributed to training course and Efficiency Ratio has been also calculated. The mean pre-test score of soldiers is 60.4 ± 21.0 and it has been significantly increased up to 82.8 ± 14.5 after the training course (p<0.05.

    Full Text Available Background: The consideration of specific trauma-associated emotions poses a challenge for the differential treatment planning in trauma therapy. Soldiers experiencing deployment-related posttraumatic stress disorder often struggle with emotions of guilt and shame as a central component of their PTSD. Objective: The purpose of this study was to examine the extent to which soldiers’ PTSD symptoms and their trauma-related guilt and shame may be affected as a function of their ability to develop compassionate imagery between their CURRENT SELF (today and their TRAUMATIZED SELF (back then. Method: The sample comprised 24 male German soldiers diagnosed with PTSD who were examined on the Posttraumatic Diagnostic Scale (PDS and two additional measures: the Emotional Distress Inventory (EIBE and the Quality of Interaction between the CURRENT SELF and the TRAUMATIZED SELF (QUI-HD: Qualität der Interaktion zwischen HEUTIGEN ICH und DAMALIGEN ICH at pre- and post-treatment and again at follow-up. The treatment used was imagery rescripting and reprocessing therapy (IRRT. Results: Eighteen of the 24 soldiers showed significant improvement in their PTSD symptoms at post-treatment and at follow-up (on their reliable change index. A significant change in trauma-associated guilt and shame emerged when compassionate imagery was developed towards one’s TRAUMATIZED SELF. The degree and intensity of the guilt and shame felt at the beginning of treatment and the degree of compassionate imagery developed toward the TRAUMATIZED SELF were predictors for change on the PDS scores. Conclusions: For soldiers suffering from specific war-related trauma involving PTSD, the use of self-nurturing, compassionate imagery that fosters reconciling with the traumatized part of the self can effectively diminish trauma-related symptoms, especially when guilt and shame are central emotions.

    Division of labor among workers is common in insect societies and is thought to be important in their ecological success. In most species, division of labor is based on age (temporal castes), but workers in some ants and termites show morphological specialization for particular tasks (physical castes). Large-headed soldier ants and termites are well-known examples of this specialization. However, until now there has been no equivalent example of physical worker subcastes in social bees or wasps. Here we provide evidence for a physical soldier subcaste in a bee. In the neotropical stingless bee Tetragonisca angustula, nest defense is performed by two groups of guards, one hovering near the nest entrance and the other standing on the wax entrance tube. We show that both types of guards are 30% heavier than foragers and of different shape; foragers have relatively larger heads, whereas guards have larger legs. Low variation within each subcaste results in negligible size overlap between guards and foragers, further indicating that they are distinct physical castes. In addition, workers that remove garbage from the nest are of intermediate size, suggesting that they might represent another unrecognized caste. Guards or soldiers are reared in low but sufficient numbers (1-2% of emerging workers), considering that bee Lestrimelitta limao, an important natural enemy, larger workers were able to fight for longer before being defeated by the much larger robber. This discovery opens up opportunities for the comparative study of physical castes in social insects, including the question of why soldiers appear to be so much rarer in bees than in ants or termites.

    Objective: To investigate the structural and functional changes of heart in elderly soldiers who was working with radiation producing equipments. The involvement of cardiovascular system in radiation and its intensity was investigated in this study. Methods: Fifty elderly males (>60 years old) who were exposed to radiation producing equipments (exposure group) and 50 elderly (>60 years old) retired male commanders without radiation exposure history (control group) were enrolled in this study. Echocardiographic evaluation of cardiac structure and function was conducted with Siemens Sonline G60 ultrasound system. 12-lead electrocardiogram (ECG) and routine physical examination had also been done in both groups. Results: Ejection fraction, minor axis reduced rate had no distinct difference between exposure group and control group (t=1.52 and t=1.68, P>0.05). Cardiac output, cardiac stroke volume, stroke index, ventricular diastolic flow velocity E/A ratios in exposure group were lower than control group (t=11.81, t=7.11 and t=7.88, P 2 =9.72, and χ 2 =5.19, P<0.05). Conclusion: Chronic low dose radiation may have effects on the cardiovascular sys-tem, so dynamic monitoring of changes in cardiac structure and function is worth on the safety and health for persons who may exposure to radiation and help to prevent early and long-term effects of radiation.

    Quantified physical activity is an important parameter for evaluating the risk of the incidence of internal and musculoskeletal disorders. The objective of this study was to evaluate the physical activity of German Soldiers on duty and during leisure time with regard to individual determinants and to evaluate if factors associated with the risk of the incidence of internal or musculoskeletal disorders are of relevance for physical activity. For this purpose, we conducted activity measurements on 169 subjects. The accelerometer-based activity sensor was worn for 7 consecutive days. The number of steps taken was evaluated as an activity marker.We observed that a high body mass index and a large waist circumference were associated with a low activity level. Women were found to be more active than men, particularly during leisure time. Personnel under 25 years of age were more physically active than those between 25 and 50 years of age. Subjects with underlying musculoskeletal disorders were less active than those who had internal disorders or were healthy. Men and overweight people run a higher risk of developing musculoskeletal and internal disorders. Health promotion should focus on raising the physical activity level with the aim of exerting a positive influence on the associated risk factors.

    There is a popular belief among the general population that Nigerian soldiers tend to have large families but this has not been substantiated with evidence-based research. The Nigerian military health authority implements female-targetted contraception strategies, with less focus on their husbands; who are the dominant fertility determinants. To determine the perception and practice of contraception among male soldiers of Sobi Cantonment, Ilorin, Nigeria, with a view to instituting male-targeted contraceptive/family planning strategies. A cross-sectional survey of 334 male soldiers using multistage sampling technique and pre-tested interviewer administered questionnaires. The respondents' approval of contraception (73.6%) and willingness to discuss it with their spouses/partners (71.6%) were high. Fear of wives/partner's sexual promiscuity (55.7%), cultural and religious beliefs (43.2%), fear of the side effects of contraceptives (29.5%) and the desire for more children (21.6%) were reported reasons for the non-approval of contraception. The prevalence of contraceptive use among the respondents was low (12.3%). There was a significant relationship between the respondents' educational level and contraceptive use (pcontraception with their spouses/partners but low contraceptive use.

    Backpack palsy (BPP) is a common aetiology of brachial plexopathy in military hospitals. We aimed to determine the incidence and risk factors of BPP in young Korean soldiers. We identified enlisted patients who were diagnosed with BPP from a review of the medical records of all the Korean military hospitals in 2011 and 2012 and investigated their clinical findings and medical study results. To identify risk factors of BPP, we also surveyed, by questionnaire, healthy recruits of a company in a training centre who had just finished night marches. We divided them according to whether they had paresthaesia and/or weakness in their arm(s) during marching and compared their characteristics. The incidence of BPP in Korean soldiers was 29.7 per 100,000 person-years (95% CI 17.2 to 24.3). Body mass index (BMI) was significantly lower in patients with BPP than it was in healthy recruits. Among healthy recruits, those who had experienced paresthaesia and/or weakness during marching had a significantly lower BMI than did those who had not. We report the incidence of BPP in young Korean soldiers. A low BMI was a risk factor for BPP. These results may be helpful in establishing a strategy for the prevention of BPP in the setting of military training. Published by the BMJ Publishing Group Limited.

    In the years following military deployment, soldiers may experience problems integrating into the community. However, little is known about the nature and prevalence of these problems and if they relate to posttraumatic symptomatology. In a prospective, longitudinal study of Danish soldiers deployed to Afghanistan in 2009 (N = 743), we assessed community reintegration difficulties 2.5 years after home coming (study sample: N = 454). Furthermore, symptoms of posttraumatic stress disorder (PTSD) were assessed before, during, and after deployment. Trajectories of PTSD symptoms from a previously published latent growth mixture modeling analysis were used to address whether community reintegration difficulties differ as a result of course and level of PTSD symptoms. Between 3.6 and 18.0% reported to have some, a lot, or extreme difficulties in reintegration domains such as interpersonal functioning, productivity, community involvement, and self-care. Mean level of reintegration difficulties differed significantly across six PTSD symptom trajectories (range 6.35-36.00); with more symptomatic trajectories experiencing greater community reintegration difficulties. Reintegration difficulties after deployment are present in less than 20% of Danish soldiers who return from Afghanistan. Difficulties are greater in individuals who follow symptomatic PTSD trajectories in the first years following deployment than in those who follow a low-stable trajectory with no or few symptoms.

    Past research revealed war trauma and posttraumatic stress disorder (PTSD) symptoms as potential predictors for domestic and community violence in crisis regions and among soldiers in different armed conflicts. The impact of family violence and other adversities experienced in childhood as well as of a combat-enhanced appeal for aggressive behavior (appetitive aggression) remains to be specified. In the present study, the authors separately predicted violence against children, intimate partner violence and community violence in 381 Burundian soldiers returning from foreign deployment and living in a post- conflict region. Using path analysis, they aimed to disentangle the independent contributions and pathways of the following variables: Exposure to war trauma and childhood familial violence, PTSD and depression symptom severity, and appetitive aggression. Childhood familial violence had an independent effect on all contexts of violence and was the only significant predictor for violence against the soldiers' own children. Intimate partner violence was additionally predicted by depression symptom severity, while community violence was additionally predicted by PTSD symptom severity and appetitive aggression. Besides war-related mental ill-health and appetitive aggression, violent experiences during childhood development must not be overlooked as a factor fueling the cycle of violence in conflict regions.

    The differentiation of workers into morphological castes represents an important evolutionary innovation that is thought to improve division of labor in insect societies. Given the potential benefits of task-related worker differentiation, it is puzzling that physical worker castes, such as soldiers, are extremely rare in social bees and absent in wasps. Following the recent discovery of soldiers in a stingless bee, we studied the occurrence of worker differentiation in 28 stingless bee species from Brazil and found that several species have specialized soldiers for colony defence. Our results reveal that worker differentiation evolved repeatedly during the last ~ 25 million years and coincided with the emergence of parasitic robber bees, a major threat to many stingless bee species. Furthermore, our data suggest that these robbers are a driving force behind the evolution of worker differentiation as targets of robber bees are four times more likely to have nest guards of increased size than non-targets. These findings reveal unexpected diversity in the social organization of stingless bees.Although common in ants and termites, worker differentiation into physical castes is rare in social bees and unknown in wasps. Here, Grüter and colleagues find a guard caste in ten species of stingless bees and show that the evolution of the guard caste is associated with parasitization by robber bees.

    Full Text Available Abstract Background Military members, injured in Afghanistan or Iraq, have returned home with multi-drug resistant Acinetobacter baumannii infections. The source of these infections is unknown. Methods Retrospective study of all Canadian soldiers who were injured in Afghanistan and who required mechanical ventilation from January 1 2006 to September 1 2006. Patients who developed A. baumannii ventilator associated pneumonia (VAP were identified. All A. baumannii isolates were retrieved for study patients and compared with A. baumannii isolates from environmental sources from the Kandahar military hospital using pulsed-field gel electrophoresis (PFGE. Results During the study period, six Canadian Forces (CF soldiers were injured in Afghanistan, required mechanical ventilation and were repatriated to Canadian hospitals. Four of these patients developed A. baumannii VAP. A. baumannii was also isolated from one environmental source in Kandahar – a ventilator air intake filter. Patient isolates were genetically indistinguishable from each other and from the isolates cultured from the ventilator filter. These isolates were resistant to numerous classes of antimicrobials including the carbapenems. Conclusion These results suggest that the source of A. baumannii infection for these four patients was an environmental source in the military field hospital in Kandahar. A causal linkage, however, was not established with the ventilator. This study suggests that infection control efforts and further research should be focused on the military field hospital environment to prevent further multi-drug resistant A. baumannii infections in injured soldiers.

    Our objective was to elucidate how culture influences internal (psychological), external (social), institutional (structural), and health care (medical) processes, which, taken together, create differential risk of comorbidity across contexts. To develop a conceptual model, we conducted qualitative research with 13 female child soldiers in Nepal. Participants gave open-ended responses to intimate partner violence (IPV) vignettes (marital rape, emotional abuse, violence during pregnancy). Twelve participants (92%) endorsed personal responses (remaining silent, enduring violence, forgiving the husband). Twelve participants endorsed communication with one's husband. Only four participants (31%) sought family support, and three contacted police. Ultimately, 12 participants left the relationship, but the majority (nine) only left after the final IPV experience, which was preceded by prolonged psychological suffering and pregnancy endangerment. In conclusion, comorbidity risks are increased in cultural context that rely on individual or couples-only behavior, lack external social engagement, have weak law and justice institutions, and have limited health services. © 2016 by the American Anthropological Association.

    Elrond, Andreas F; Høgh, Annie; Andersen, Søren B

    2018-01-01

    Background : Soldiers' perception of leadership during military deployment has gained research attention as a potentially modifiable factor to buffer against the development of postdeployment post-traumatic stress disorder (PTSD). Within nonmilitary research, the organizational justice (OJ) framework, i.e. distributive justice, procedural justice (PJ) and interactional justice (IJ), has been found to relate to mental health outcomes. Aspects of OJ may, therefore, be protective against PTSD. Objectives : We examined the prospective relationship between aspects of OJ, namely the perceptions of PJ and IJ by subordinate soldiers without leadership obligations in relationship to immediate superiors and PTSD. Method : Participants were soldiers ( n =  245) deployed to Helmand Province in Afghanistan in 2009. Logistic regression procedures were used. The primary analysis measured PTSD cases using the Structured Clinical Interview for DSM-IV-TR Axis-I Disorder (SCID) 2½ years after homecoming. PJ/IJ was measured during deployment with a 6-item composite measure ranging from 0 to 12. Supplementary primary analyses were performed with PJ/IJ measured before and immediately after deployment. A secondary PJ/IJ analysis also tested against four postdeployment measures with the Post-Traumatic Stress Disorder Checklist Civilian (PCL-C) dichotomized at screening symptom levels. Results : Higher levels of perceived PJ/IJ for soldiers without leadership obligations during deployment had a prospective relation (OR = 0.86, 95% CI = 0.75-0.98) with PTSD on the SCID 2½ years after homecoming after adjustment for factors including predeployment PTSD symptoms, trauma and combat exposure, and state affectivity. Similar results were found by measuring PJ/IJ before (OR = 0.83, 95% CI = 0.71-0.95) but not immediately after homecoming (OR = 0.97, 95% CI = 0.85-1.11). A relationship with PTSD symptoms at the screening level at the four measurements of PCL-C was found, but only

  5. Soldiers at risk for individual readiness or morale problems during a six-month peacekeeping deployment to the Sinai.

    Schumm, W R; Bell, D B

    2000-10-01

    Longitudinal data were examined to predict soldiers' morale, satisfaction with Army life, and the effects of family issues on performance of duties during an overseas deployment (Sinai peacekeeping force during the spring of 1995). Few variables were significant predictors of the outcome measures; however, rank, leaders' support for families, prior satisfaction with Army life and with information released about the deployment appeared to predict better outcomes during the deployment. Rank and leaders' support for families appeared to be more important for married soldiers while satisfaction with predeployment information seemed to be more important for single soldiers. Those who were worried about the effects of the deployment on their families also tended to report interference with their duty performance because of family concerns, but that effect was offset by perceived leaders' concern for families. In conclusion, it appears to the authors that the pre-existing factors studied had much less to do with deployment outcomes than did leadership success before and during the deployment. That's good news for Army leaders about their power to have a positive effect on soldiers' morale during overseas deployments but may be bad news for anyone hoping to find a "magic bullet" for pre-identification of soldiers most likely to retain high morale, regardless of their leadership's competence during an overseas deployment.

    The objective of this study was to explore whether ketamine prevents or exacerbates acute or post-traumatic stress disorders in military trauma patients. We conducted a retrospective study of a database from the French Military Health Service, including all soldiers surviving a war injury in Afghanistan (2010-2012). The diagnosis of post-traumatic stress disorder was made by a psychiatrist and patients were analysed according to the presence or absence of this condition. Analysis included the following covariables: age; sex; acute stress disorder; blast injury; associated fatality; brain injury; traumatic amputation; Glasgow coma scale; injury severity score; administered drugs; number of surgical procedures; physical, neurosensory or aesthetic sequelae; and the development chronic pain. Covariables related to post-traumatic and acute stress disorders with a p ≤ 0.10 were included in a multivariable logistic regression model. The data from 450 soldiers were identified; 399 survived, of which 274 were analysed. Among these, 98 (36%) suffered from post-traumatic stress disorder and 89 (32%) had received ketamine. Fifty-four patients (55%) in the post-traumatic stress disorder group received ketamine vs. 35 (20%) in the no PTSD group (p stress disorder and total number of surgical procedures were independently associated with the development of post-traumatic stress disorder. In this retrospective study, ketamine administration was not a risk factor for the development of post-traumatic stress disorder in the military trauma setting. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

Including mild TBI and concussion, TBI's are prevalent in soldiers returning from Iraq and Afghanistan as well as in domestic athletes. Long-term risks of single and cumulative head impact dosage may present in the form of post traumatic stress disorder (PTSD), depression, suicide, Chronic Traumatic Encephalopathy (CTE), dementia, Alzheimer's and Parkinson's diseases. Quantifying head impact dosage and understanding associated risk factors for the development of long-term sequelae is critical toward developing guidelines for TBI exposure and post-exposure management. The current knowledge gap between head impact exposure and clinical outcomes limits the understanding of underlying TBI mechanisms, including effective treatment protocols and prevention methods for soldiers and athletes. In order to begin addressing this knowledge gap, Cleveland Clinic is developing the "Intelligent Mouthguard" head impact dosimeter. Current testing indicates the Intelligent Mouthguard can quantify linear acceleration with 3% error and angular acceleration with 17% error during impacts ranging from 10g to 174g and 850rad/s2 to 10000rad/s2, respectively. Correlation was high (R2 > 0.99, R2 = 0.98, respectively). Near-term development will be geared towards quantifying head impact dosages in vitro, longitudinally in athletes and to test new sensors for possible improved accuracy and reduced bias. Long-term, the IMG may be useful to soldiers to be paired with neurocognitive clinical data quantifying resultant TBI functional deficits.

    To evaluate the MR imaging findings of fatigue fractures of the lower extremity in young soldiers. In 22 cases of fatigue fractures of the lower extremity in young soldiers proven by clinical findings and radiological follow up, the MRI findings were retrospectively evalvated. All patients were male and aged between 19 and 21 years. As seen on MRI, the bone marrow edema, intramedullary low signal intensity band, cortical fracture line, periosteal reaction, surrounding soft tissue edema, and enhancement pattern were analyzed and the site of involvement was determined in the axial plane. The locations of fatigue fractures of the lower extremity were the tibia (n=12), fibula (n=8), femur (n=1) and second metatarsus (n=1). All occurred in diaphyses: the junction of the proximal and middle (n=10), middle (n=9), proximal (n=2), and distal shaft (n=1). The sites of involvement were the posteromedial (n=6) and medial side (n=6) of the tibia, and the entire portion of the fibula(n=5) in the axial plane. MRI findings were bone marrow edema in 20 cases, intramedullary low signal intensity band in 14 (which were continuous with the cortex or cortical fracture line), cortical fracture line in 13, and periosteal reaction and surrounding soft tissue edema in all. On gadolinium-enhanced images, enhancement was seen in the bone marrow in 19 cases, in the subperiosteal region in 18, and in the surrounding soft tissue in 22. In fatigue fractures of the lower extremity in young soldiers, the main locations were the tibia and fibula, and characteristic MR imaging findings were intramedullary low signal intensity bands, which were continuous with the cortex or cortical fracture line and often accompanied by bone marrow edema, periosteal reaction, and surrounding soft tissue edema

    Psychological health is vital for effective employees, especially in stressful occupations like military and public safety sectors. Yet, until recently little empirical work has made the link between requisite psychological resources and important mental health outcomes across time in those sectors. In this study we explore the association between 14 baseline psychological health attributes (such as adaptability, coping ability, optimism) and mental health outcomes following exposure to combat deployment. Retrospective analysis of all U.S. Army soldiers who enlisted between 2009 and 2012 and took the Global Assessment Tools (GAT) before their first deployment (n = 63,186). We analyze whether a soldier screened positive for depression and posttraumatic stress disorder (PTSD) after returning from deployment using logistic regressions. Our key independent variables are 14 psychological attributes based on GAT, and we control for relevant demographic and service characteristics. In addition, we generate a composite risk score for each soldier based on the predicted probabilities from the above multivariate model using just baseline psychological attributes and demographic information. Comparing those who scored in the bottom 5 percentile of each attribute to those in the top 95 percentile, the odds ratio of post-deployment depression symptoms ranges from 1.21 (95% CI 1.06, 1.40) for organizational trust to 1.73 (CI 1.52, 1.97) for baseline depression. The odds ratio of positive screening of PTSD symptoms ranges from 1.22 for family support (CI 1.08, 1.38) to 1.51 for baseline depression (CI 1.32, 1.73). The risk profile analysis shows that 31% of those who screened positive for depression and 27% of those who screened positive for PTSD were concentrated among the top 5% high risk population. A set of validated, self-reported questions administered early in a soldier's career can predict future mental health problems, and can be used to improve workforce fit and

    The Israeli National Health Insurance Law allocates a national healthcare budget to the sickness funds, which provide medical care to civilian population. Medical care for members of the IDF is financed through the budget of the Ministry of Defense and is not included in the national healthcare budget. Benefits provided to soldiers serving in the permanent forces are far more extensive than those provided to civilians. Because of no co-payments, poor management, and the cost-based budget, military healthcare costs in Israel are expected to exceed civilian healthcare costs, adjusting for age and sex. The present paper derives age- and sex-based capitation rates for military personnel, and compares military and civilian age-based expenditure and capitation rates. The study population comprised career soldiers and civilians aged 21-54 years. Expenses of career soldiers were calculated to provide information on the financial costs of medical services for each age group in 2003. Overall expenses for women were higher than for men in all age groups. As anticipated, the older the group, the higher the total expenditure for both men and women. In-patient care represented a higher percentage of the total costs for men (28.3%) than for women (22.1%). Emergency room care was higher for women in the 22-24 age group but comparable to that of men in higher age groups. Specialist visits represented a significantly higher percentage of the total costs for women than for men in the 22-24 and 25-34 age groups (by 6% and 15%, respectively). The difference decreased to 13% in the 35-44 age groups and, in the 45-54 age group, the difference for men was 14% higher than for women. Military costs were similar to civilian costs in the 22-24 age groups, higher in the following two groups, and lower in the 45-54 age group. Like in other organizations, military healthcare services might benefit from outsourcing. The inequality in medical services to soldiers and civilians, the over-use of the

    We investigated fitness, military rank and survival of facial phenotypes in large-scale warfare using 795 Finnish soldiers who fought in the Winter War (1939-1940). We measured facial width-to-height ratio-a trait known to predict aggressive behaviour in males-and assessed whether facial morphology could predict survival, lifetime reproductive success (LRS) and social status. We found no difference in survival along the phenotypic gradient, however, wider-faced individuals had greater LRS, but achieved a lower military rank.

    Full Text Available Performing an online health search is a popular activity conducted on the Internet. Research studies from developed countries provide information on source used, type of search performed and devices used to perform the search. However, the same cannot be said about the online health information searching scene in South East Asia. Online health information searching is gaining popularity in South East Asia. Citizens in these countries are turning to the Internet to obtain health information quickly. Current research studies pertaining to online health information searching in South East Asian is limited, particularly relating to search experiences of South East Asian health searchers. Search experience is pertinent asit could deter or encourage the possibility of conducting future health searches. In this research study, a user study was conducted to describe the online search experience of South East Asian health searchers. A face to face interview with 50 participants was conducted. The interview was audio recorded and transcribed verbatim. Results indicate participants have positive and negative search experiences. In some cases, post search outcomes influenced the search experience. Results of this research study contribute to the growing domain of knowledge in relation to online health information searching. Results of this study also provide an understanding pertaining to the search experience of South East Asian online health searchers.

    2000-05-01

    The research which the Defence Evaluation and Research Agency (DERA) has conducted on hydrogen storage and production methods was presented and their applicability to soldier portable applications was discussed. Polymer electrolyte membrane (PEM) fuel cells are considered to be the future power source for solider-portable equipment such as army radios. Advances in fuel cell technology has resulted in improvements in specific power and power density as well as reductions in Pt loading and cost. However, a viable in-service power source is still required. This fuel source is likely to be hydrogen because it has a high energy per unit weight and has a simple reaction with oxygen to produce water as the only by-product. In the future, methanol may be used as the fuel source but currently methanol fuel cells demonstrate poorer performance than those running on hydrogen. A vital part of a fuel cell system, therefore, is hydrogen storage, of which there are two basic types; physical and chemical storage. In addition to weight, other important factors to be considered in a storage system are cost, reliability and safety. This paper described each physical storage method including hydrogen stored as a compressed gas, as a cryogenic liquid, reversibly absorbed in intermetallic alloys and reversibly adsorbed onto carbon materials such as nonofibres. Liquid hydrogen storage is only feasible for larger scale applications such as electric vehicles and is not practical for portable applications. A man-portable fuel cell is likely to be either pressure cylinders or reversible metal hydrides. 6 refs., 1 tab., 10 figs.

    There has been a considerable amount of scholarly attention to the relationship between neighborhood effects and conduct disorder, particularly in recent years. Having said this, it has been nearly two decades since a comprehensive synthesis of this literature has been conducted. Relying on a detailed and comprehensive search strategy and inclusion criteria, this article offers a systematic and interdisciplinary review of 47 empirical studies that have examined neighborhood effects and conduct disorder. Described results suggest that there are generally robust linkages between adverse neighborhood factors and conduct disorder and externalizing behavior problems, as 67 of the 93 (72.04%) effect sizes derived from these studies yielded statistically significant neighborhood effects. The review also identifies salient mediating and moderating influences. It discusses study limitations and directions for future research as well.

    Many soldiers with mental illness (SWMIs) struggle with the decision whether to disclose their condition in or outside the military. This study therefore explored views on (self-)labeling as 'mentally ill', experiences of discrimination and coping, risks and benefits of (non-)disclosure, service use, disclosure decisions and consequences of disclosing. Active-duty SWMIs as well as soldiers without mental illness (commanding officers; enlisted ranks) and military social workers participated in focus groups. Transcripts were analyzed using qualitative content analysis. SWMIs perceived negative stereotypes about their group (weakness, incompetence, blame, malingering) and saw stigma as a barrier to help-seeking. Being labeled 'mentally ill' was seen as harmful for one's career. Self-labeling led to poor self-esteem, greater need for help and feelings of weakness. Many SWMIs had experienced discrimination, such as gossip or inappropriate comments. Social isolation was a disadvantage of secrecy. Most SWMIs preferred selective disclosure and many did not disclose to their family. Military staff without mental illness expressed partly different views and described organizational challenges posed by SWMIs. Our findings suggest that disclosure decisions are personal and difficult and that stigma remains a barrier to re-integration and recovery of SWMIs in the military. Implications for interventions to support SWMIs are discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

    Pre-clinical and clinical studies have shown acute stress may impair working memory and visuo-spatial ability. This study was designed to clarify the nature of stress-induced cognitive deficits in soldiers and how such deficits may contribute to operational or battlefield errors. One hundred eighty-four Special Operations warfighters enrolled in Survival School completed pre-stress measures of dissociation and trauma exposure. Subjects were randomized to one of three assessment groups (Pre-stress, Stress, Post-stress) and were administered the Rey Ostereith Complex Figure (ROCF). All subjects completed post-stress measures of dissociation. ROCF copy and recall were normal in the Pre- and Post-stress groups. ROCF copy and recall were significantly impaired in the Stress Group. Stress group ROCF copy performance was piecemeal, and ROCF recall was impaired. Symptoms of dissociation were negatively associated with ROCF recall in the Stress group. Baseline dissociation and history of traumatic stress predicted cognitive impairment during stress. Stress exposure impaired visuo-spatial capacity and working memory. In rats, monkeys, and humans, high dopamine and NE turnover in the PFC induce deficits in cognition and spatial working memory. Improved understanding of stress-induced cognitive deficits may assist in identification of soldiers at risk and lead to the development of better countermeasures.

  7. A multimodal interface for real-time soldier-robot teaming

    2016-05-01

    Recent research and advances in robotics have led to the development of novel platforms leveraging new sensing capabilities for semantic navigation. As these systems becoming increasingly more robust, they support highly complex commands beyond direct teleoperation and waypoint finding facilitating a transition away from robots as tools to robots as teammates. Supporting future Soldier-Robot teaming requires communication capabilities on par with human-human teams for successful integration of robots. Therefore, as robots increase in functionality, it is equally important that the interface between the Soldier and robot advances as well. Multimodal communication (MMC) enables human-robot teaming through redundancy and levels of communications more robust than single mode interaction. Commercial-off-the-shelf (COTS) technologies released in recent years for smart-phones and gaming provide tools for the creation of portable interfaces incorporating MMC through the use of speech, gestures, and visual displays. However, for multimodal interfaces to be successfully used in the military domain, they must be able to classify speech, gestures, and process natural language in real-time with high accuracy. For the present study, a prototype multimodal interface supporting real-time interactions with an autonomous robot was developed. This device integrated COTS Automated Speech Recognition (ASR), a custom gesture recognition glove, and natural language understanding on a tablet. This paper presents performance results (e.g. response times, accuracy) of the integrated device when commanding an autonomous robot to perform reconnaissance and surveillance activities in an unknown outdoor environment.

    To test the application of doubly labeled water under adverse field conditions, energy expenditures of 16 special operations soldiers were measured during a 28-day field training exercise. Subjects were matched by fat-free mass and divided equally between an ad libitum ready-to-eat meal diet and a 2,000 kcal/day lightweight ration. Subjects recorded intakes daily, and body composition was measured before and after the exercise. At the beginning of the study, subjects moved to a new northerly location and, therefore, a new water supply. To compensate for this, a group of soldiers who did not receive heavy water was followed to measure isotopic base-line changes. Energy expenditure by doubly labeled water was in agreement with intake/balance (3,400 ± 260 vs. 3,230 ± 520 kcal/day). The overall coefficient of variation of energy expenditure by doubly labeled water was half that of intake/balance (7.6 vs. 16.1%). The coefficient of variation of repeat measures with doubly labeled water was 7.3%. Energy expenditure of the ready-to-eat meal group, 3,540 ± 180 kcal/day, was not significantly different from the lightweight ration group, 3,330 ± 301 kcal/day. Doubly labeled water was valid under field conditions

  9. Two war-torn soldiers: combat-related trauma through an intersubjective lens.

    Carr, Russell B

    2013-01-01

    The author, himself an Iraq war veteran, presents a contemporary psychodynamic understanding, known as intersubjective therapy, of combat-related Post-traumatic Stress Disorder (PTSD). At the onset of this case example, the patient was highly suicidal and his PTSD symptoms had not responded to a first-line treatment: manualized cognitive processing therapy. Robert Stolorow's intersubjective, psychodynamic approach to traumatic emotional experiences was then selected for treatment, and illustrates how combat in Afghanistan shattered this soldier's world and self experience. Therapeutic action arises from this intersubjective perspective by providing a relational home so that unendurable emotions can be borne, processed, and integrated to achieve a more constant and individualized sense of self. Being a two-person model of therapy, the author also describes how his work with this traumatized soldier affected him, ultimately contributing to his own sense of authentic existing. The author discusses the need for therapists to recognize and acknowledge to traumatized patients their shared finitude and the ubiquity of trauma. In the Postscript, the patient describes what he felt was therapeutic and contrasts this to his previous experiences with manualized cognitive processing therapy.

    Black soldier fly larvae are converters of organic waste into edible biomass, of which the composition may depend on the substrate. In this study, larvae were grown on four substrates: chicken feed, vegetable waste, biogas digestate, and restaurant waste. Samples of prepupae and substrates were freeze-dried and proximate, amino acid, fatty acid and mineral analyses were performed. Protein content of prepupae varied between 399 and 431 g kg -1 dry matter (DM) among treatments. Differences in amino acid profile of prepupae were small. On the other hand, the ether extract (EE) and ash contents differed substantially. Prepupae reared on digestate were low in EE and high in ash (218 and 197 g kg -1 DM, respectively) compared to those reared on vegetable waste (371 and 96 g kg -1 DM, respectively), chicken feed (336 and 100 g kg -1 DM, respectively) and restaurant waste (386 and 27 g kg -1 DM, respectively). Prepupal fatty acid profiles were characterised by high levels of C12:0 in all treatments. Since protein content and quality were high and comparable for prepupae reared on different substrates, black soldier fly could be an interesting protein source for animal feeds. However, differences in EE and ash content as a function of substrate should be considered. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    This report analyzes the occurrence of Cryptosporidium spp., E. histolytica, and G. intestinalis in stool of returnees from military deployments and the impact of hygiene precautions. Between 2007 and 2010, stool samples of 830 returnees that were obtained 8-12 weeks after military deployments in Afghanistan, Uzbekistan, the Balkans, Democratic Republic of the Congo/Gabonese Republic, and Sudan and 292 control samples from non-deployed soldiers were analyzed by PCR for Cryptosporidium spp., E. histolytica, G. intestinalis, and the commensal indicator of fecal contamination E. dispar. Data on hygiene precautions were available. The soldiers were questioned regarding gastrointestinal and general symptoms. Among 1122 stool samples, 18 were positive for G. intestinalis, 10 for E. dispar, and no-one for Cryptosporidium spp. and E. histolytica. An increased risk of acquiring chronic parasitic infections in comparison with non-deployed controls was demonstrated only for G. intestinalis in Sudan, where standardized food and drinking water hygiene precautions could not be implemented. Standard food and drinking water hygiene precautions in the context of screened military field camps proved to be highly reliable in preventing food-borne and water-borne chronic infections and colonization by intestinal protozoa, leading to detection proportions similar to those in non-deployed controls.

  12. Rehabilitation and restoration: orthopaedics and disabled soldiers in Germany and Britain in the First World War.

    Anderson, Julie; Perry, Heather R

    2014-01-01

    This article offers a comparative analysis of the evolution of orthopaedics and rehabilitation within German and British military medicine during the Great War. In it, we reveal how the field of orthopaedics became integral to military medicine by tracing the evolution of the discipline and its practitioners in each nation during the war. In doing so, however, we document not only when and why both medical specialists and military officials realized that maintaining their respective national fighting forces depended upon the efficient rehabilitation of wounded soldiers, but also how these rehabilitative practices and goals reflected the particularities of the military context, civilian society and social structure of each nation. Thus, while our comparison reveals a number of similarities in the orthopaedic developments within each nation as a response to the Great War, we also reveal significant national differences in war-time medical goals, rehabilitation treatments and soldierly 'medical experiences'. Moreover, as we demonstrate, a social and cultural re-conceptualization of the disabled body accompanied the medical advancements developed for him; however, this re-conceptualization was not the same in each nation. Thus, what our article reveals is that although the guns of August fell silent in 1918, the war's medical experiences lingered long thereafter shaping the future of disability medicine in both nations.

  13. Soldiers, Artisans, Cultivators and Revolutionaries: The Movement of Sikhs in the Indian Ocean

    Full Text Available The geography of Punjab, a land-locked region divided between India and Pakistan, makes it an unlikely player in oceanic sojourns. But imperial interventions in Punjab in the middle of the 19th century triggered movements from Punjab that inserted this region in the littoral narrative of the Indian Ocean. Unlike the movements of lascars and traders, who have been central to the revisionist histories of the Indian Ocean, those from Punjab have not featured in oceanic dialogues. The absence of Sikhs in Indian Ocean studies is largely due to the silence of Sikh soldiers, skilled craftsmen and cultivators with largely rural roots who were uprooted to strange lands. The confusion of Sikhs with Hindus, Muslims and, even Afghans, in the colonial era, as well as the classification of Punjabi Muslims as Pakistani in the post-colonial, further problematizes the Sikh migration narrative. Drawing on a wide range of official and unofficial historical sources, this essay argues that twin developments in Punjab, namely the construction of Sikhs as ‘a martial race’ and their integration into the imperial capitalist economy, connects the movements of soldiers and policemen to Shanghai, Hong Kong, the Straits Settlements and Kenya with those of skilled artisans to Mombasa and Uganda. Keywords: Sikhs, Indian Ocean, labour migration, cultural identity

    Risk factors for concussion in active-duty military service members are poorly understood. The present study examined the association between self-reported concussion history and genetics (apolipoprotein E [APOE], brain-derived neurotrophic factor [BDNF], and D2 dopamine receptor genes [DRD2]), trait personality measures (impulsive-sensation seeking and trait aggression-hostility), and current alcohol use. The sample included 458 soldiers who were preparing to deploy for Operation Iraqi Freedom/Operation Enduring Freedom. For those with the BDNF Met/Met genotype, 57.9% (11/19) had a history of one or more prior concussions, compared with 35.6% (154/432) of those with other BDNF genotypes (p = 0.049, odds ratio [OR] = 2.48). APOE and DRD2 genotypes were not associated with risk for past concussions. Those with the BDNF Met/Met genotype also reported greater aggression and hostility personality characteristics. When combined in a predictive model, prior military deployments, being male, and having the BDNF Met/Met genotype were independently associated with increased lifetime history of concussions in active-duty soldiers. Replication in larger independent samples is necessary to have more confidence in both the positive and negative genetic associations reported in this study.

    Full Text Available This essay is an account of the making of England and her Soldiers (1859 by Harriet Martineau and Florence Nightingale. The book is a literary account of the Crimean War, written by Martineau and based on Nightingale’s statistical studies of mortality during the conflict. Nightingale was passionate about statistics and healthcare. Whilst working as a nurse in the Crimea, she witnessed thousands of soldiers die of infectious diseases that might have been prevented with proper sanitation. After the war, she launched a campaign to convince the British government to make permanent reforms to military healthcare, compiling a dataset on mortality in the Crimea. She worked with the government’s Royal Commission investigating healthcare during the war, but also worked privately with Martineau to publicise her findings. Martineau and Nightingale grasped that the lay reader was more receptive to statistical information in a literary format than in dense statistical reports. As such, Nightingale’s data was interwoven with Martineau’s text. The pair illustrated their book with Nightingale’s ‘Rose Diagram’, a statistical graphic which simply illustrated the rate of mortality.

    Child soldiers often experience complex trauma as victims and perpetrators, and feelings of guilt may affect their psychological health. The relationship between the children's traumatic experiences as victims or perpetrators, their perception of themselves as victim or perpetrator, guilt and psychopathology were investigated: of the 330 former child soldiers interviewed, 50.8 % perceived themselves as victims and 19.1 % as perpetrators. On psychopathology measures, scores within the clinical range were 33 % for posttraumatic stress disorder (PTSD), 36.4 % for major depressive disorder (MDD), and 26.1 % for externalizing problems. Low socio-economic status, traumatic experience as perpetrator, and guilt were significant predictors of PTSD. Significant predictors of MDD were low socio-economic status, traumatic experiences as victim, and guilt. A greater number of traumatic experiences as perpetrator and guilt were associated with externalizing problems. The current paper underscores the significance of guilt following traumatic experiences and has implications for the development of clinical interventions for war-affected children.

  17. "The Service I Rendered Was Just as True": African American Soldiers and Veterans as Activist Patients.

    Adler, Jessica L

    In this article, I examine how African American soldiers and veterans experienced and shaped federally sponsored health care during and after World War I. Building on studies of the struggles of Black leaders and health care providers to win professional and public health advancement in the 1920s and 1930s, and of advocates to mobilize for health care rights in the mid-20th century, I focus primarily on the experiences and activism of patients in the interwar years. Private and government correspondence, congressional testimony, and reports from Black newspapers reveal that African American soldiers and veterans communicated directly with policymakers and bureaucrats regarding unequal treatment, assuming roles as "policy actors" who viewed health and medical care as "politics by other means." In the process, they drew attention to the paradoxes inherent in expanding government entitlements in the era of Jim Crow, and helped shape a veterans' health system that emerged in the 1920s and remained in place for the following century. They also laid the groundwork for the system's precedent-setting desegregation, referred to by advocates of the time as "a shining example to the rest of the country."

  2. Rhesus factor modulation of effects of smoking and age on psychomotor performance, intelligence, personality profile, and health in Czech soldiers.

    Directory of Open Access Journals (Sweden)

    Jaroslav Flegr

    Full Text Available BACKGROUND: Rhesus-positive and rhesus-negative persons differ in the presence-absence of highly immunogenic RhD protein on the erythrocyte membrane. This protein is a component of NH(3 or CO(2 pump whose physiological role is unknown. Several recent studies have shown that RhD positivity protects against effects of latent toxoplasmosis on motor performance and personality. It is not known, however, whether the RhD phenotype modifies exclusively the response of the body to toxoplasmosis or whether it also influences effects of other factors. METHODOLOGY/PRINCIPAL FINDINGS: In the present cohort study, we searched for the effects of age and smoking on performance, intelligence, personality and self-estimated health and wellness in about 3800 draftees. We found that the positive effect of age on performance and intelligence was stronger in RhD-positive soldiers, while the negative effect of smoking on performance and intelligence was of similar size regardless of the RhD phenotype. The effect of age on four Cattell's personality factors, i.e., dominance (E, radicalism (Q(1, self-sentiment integration (Q(3, and ergic tension (Q(4, and on Cloninger's factor reward dependency (RD was stronger for RhD-negative than RhD-positive subjects, while the effect of smoking on the number of viral and bacterial diseases was about three times stronger for RhD-negative than RhD-positive subjects. CONCLUSIONS: RhD phenotype modulates the influence not only of latent toxoplasmosis, but also of at least two other potentially detrimental factors, age and smoking, on human behavior and physiology. The negative effect of smoking on health (estimated on the basis of the self-rated number of common viral and bacterial diseases in the past year was much stronger in RhD-negative than RhD-positive subjects. It is critically needed to confirm the differences in health response to smoking between RhD-positive and RhD-negative subjects by objective medical examination in

    To provide the advanced interventional procedure of zygapophysial joint neurotomy to soldiers meeting the diagnostic criteria in a combat environment and thus reduce medical evacuations of soldiers from a theater of war. Retrospective chart review was performed on three consecutive soldiers who received neuroablation of the lumbar ZP joint. Patients received single MBB with 1 cc of 1% lidocaine at the b/l L3-L5 levels considered diagnostic if >50% analgesia was achieved concordant with duration of anesthetic.   All procedures were co-performed by the two authors at the Ibn Sina hospital in Baghdad, Iraq over a 3-month period. Three consecutive patients with >50% pain relief from diagnostic medial branch blocks were treated with radiofrequency ablation of the bilateral L3-L4 medial branch nerves and L5 posterior primary ramus. Sensory test stimulation at 50 Hz and motor stimulation at 2 Hz were performed at each level. The nerves were then lesioned at 80° Centigrade for 90 seconds after injection of lidocaine and methylprednisolone. Procedure was considered successful if patients were able to wear body armour without significant discomfort (at least 1 hour/day). Medical evacuation from Iraq was prevented and all soldiers returned to rigorous combat duties including the wearing of body armour daily. We believe to be the first to report on the use of RF nerve ablation in a war time setting and with this functional outcome. Wiley Periodicals, Inc.

    Promoting healthy eating among Soldiers is a priority to the Army due to the link between nutrition and performance. The Army typically uses nutrition education to encourage Soldiers to make healthier food choices with low emphasis on other psychosocial determinants of food choice behaviors. Drill Sergeant Candidates (n = 575) completed surveys assessing nutrition knowledge, eating identity type, and food choice behaviors including fruit and vegetable intake, skipping meals, and eating out frequency. In multiple linear regression models using full-information maximum likelihood estimation while controlling for race/ethnicity, education, and marital status, we examined relationships between nutrition knowledge, a healthy eating identity, and Soldiers' food choice behaviors. The study was approved by the Department of Defense and University of South Carolina's Institutional Review Boards. A healthy eating identity was positively associated with greater fruit and vegetable consumption (p eating out frequency (p healthy eating identity may be more effective for promoting healthy food choice behaviors than nutrition education alone. Determining if various points in a Soldier's career could be leveraged to influence a healthy eating identity and behaviors could be an important strategy to improve compliance with health promotion programs.

    Outbreaks of cutaneous leishmaniasis are relatively common among soldiers involved in nocturnal activities in tropical forests. We investigated the population dynamics of sand flies in a military training camp located in a remnant of Atlantic rainforest in northeastern Brazil, where outbreaks of cutaneous leishmaniasis have sporadically been described. From July 2012 to July 2014, light traps were monthly placed in 10 collection sites, being nine sites located near the forest edge and one near a sheep and goat stable. Light traps operated from 5:00 pm to 6:00 am, during four consecutive nights. Leishmania infection in sand flies was assessed using a fast real-time PCR assay. Cases of cutaneous leishmaniasis among soldiers were also investigated. In total, 24,606 sand flies belonging to 25 species were identified. Males (n = 12,683) predominated over females (n = 11,923). Sand flies were present during all months, being more numerous in March (n = 1,691) and April 2013 (n = 3,324). Lutzomyia choti (72.9%) was the most abundant species, followed by Lutzomyia longispina (13.8%), Lutzomyia complexa (5.3%), representing together >90% of the sand flies collected. Forty cases of cutaneous leishmaniasis were recorded among soldiers from January 2012 to December 2014. Leishmania isolates were obtained from eight patients and were all characterized as Leishmania braziliensis. Soldiers and anyone overnighting in Atlantic rainforest remnants should adopt preventative measures such as the use of repellents on bare skin or clothes and insecticide-treated tents.

    Obesity is currently considered to be the most frequent metabolic disease worldwide, not only in developed but also in developing countries. The aim of this work was to describe the development of health status in soldiers of the Armed Forces of the Czech Republic (ACR) and to emphasizethe markers of non-communicable diseases. Our study describes the anthropometric and biochemical parameters of a large group of Czech Army professional soldiers. Data were obtained over a period of 11 years. During the monitored period, from 1999 to 2009, military physicians carried out on the average 6,360 examinations on professional soldiers per year and monitored their health and nutritional status with the aim of preventing the risk factors of non-communicable diseases. These examinations are compulsory for all professional soldiers at the age of 25, 30, 33, and 36 years. From the age of 39, these examinations are carried out every year till the end of their career. Besides taking personal histories and carrying out standard physical examinations, blood was taken for biochemical examination. The following anthropometric parameters were monitored: body constitution using body mass index (BMI) and waist circumference. Our study describes only part of the data concerning anthropometric and biochemical parameters of professional soldiers which were obtained over a period of 11 years. Average BMI values in men were in the overweight range (26.5-27 kg/m2). Average values of waist circumference, however, ranged from 91.9 cm to 93.4 cm. Between the first and the last year of monitoring a statistically significant decrease in these values ranging from 93.4 ± 9.8 cm to 92.7 ± 9.5 cm (p values of total cholesterol, triglycerides and LDL cholesterol was observed; from 5.5 ± 1.1 mmol/L to 5.1 ± 1.0 mmol/L (p values in the overweight range was observed. Although the number of overweight soldiers was overestimated as a result of the inclusion of individuals with increased body weight due

    Armed conflict imposes huge hardship on young people living in war zones. This study assessed former child soldiers' experience and perception of stress in common war events during the armed conflict in northern Uganda and compares it with their non-recruited counterparts. To investigate whether child soldiers experienced more severe exposure to war events, and explore how war might affect youths differently, depending on the co-occurrence of these events. The study was undertaken in four northern Ugandan districts in 22 secondary schools with a sample size of 981 youths, about half of whom had been child soldiers. The participants completed a questionnaire on socio-demographic characteristics and stressful war events which was analyzed using descriptive statistics, a probabilistic index and correlation network analysis. Former child soldiers had significantly greater experience of war events than their non-recruited counterparts. The violence of war is more central in their experience and perception of stress, whereas the scarcity of resources and poor living conditions are most central for non-recruited participants. The extent to which a war event, such as separation from the family, is perceived as stressful depends on the experience and perception of other stressful war events, such as confrontation with war violence for former child soldiers and life in an Internally Displaced Persons' camp for non-recruited participants. The network approach permitted demonstration of the many ways in which war-affected youths encounter and appraise stressful war events. War events might function as moderators or mediators of the effect that other war events exert on the lives and well-being of young people living in war zones. This demands comprehensive and individualized assessment.

    Observers can quickly search among shaded cubes for one lit from a unique direction. However, replace the cubes with similar 2-D patterns that do not appear to have a 3-D shape, and search difficulty increases. These results have challenged models of visual search and attention. We demonstrate that cube search displays differ from those with “equivalent” 2-D search items in terms of the informativeness of fairly low-level image statistics. This informativeness predicts peripheral discriminability of target-present from target-absent patches, which in turn predicts visual search performance, across a wide range of conditions. Comparing model performance on a number of classic search tasks, cube search does not appear unexpectedly easy. Easy cube search, per se, does not provide evidence for preattentive computation of 3-D scene properties. However, search asymmetries derived from rotating and/or flipping the cube search displays cannot be explained by the information in our current set of image statistics. This may merely suggest a need to modify the model's set of 2-D image statistics. Alternatively, it may be difficult cube search that provides evidence for preattentive computation of 3-D scene properties. By attributing 2-D luminance variations to a shaded 3-D shape, 3-D scene understanding may slow search for 2-D features of the target. PMID:25780063

    The present study examined behavioral health outcomes, risk behaviors, aggression, alcohol misuse, marital satisfaction, and attitudes toward reintegration associated with an alternative, front-loaded reintegration strategy compared with a more standardized reintegration process in soldiers returning from combat deployments. The type of reintegration strategy used did not predict differences in posttraumatic stress disorder (PTSD) symptoms, alcohol misuse, aggression, and marital satisfaction, although slightly higher reports of risk behaviors were found in the unit using the standard reintegration approach even after controlling for demographic covariates and combat exposure. These findings may help guide leadership when making decisions regarding reintegration approaches in the future. PsycINFO Database Record (c) 2014 APA, all rights reserved.

    2016-01-01

    Exertional rhabdomyolysis is a complication of sickle cell trait (SCT) likely first reported in the military population over 40 years ago. Although commonly a benign condition, numerous studies and case reports have identified SCT positive patients to be at increased risk for rhabdomyolysis, compartment syndrome and sudden cardiac death. We report a recent case of an SCT positive African American active duty male Soldier who suffered exertional rhabdomyolysis following an Army Physical Fitness Test. His course was complicated by acute renal failure requiring hemodialysis, and he eventually recovered renal function. The diagnosis was significantly delayed despite a typical clinical presentation and available SCT screening results. The case highlights the importance of the recognition of SCT as a risk factor for severe rhabdomyolysis, and suggests more must be done for an effective SCT screening program for the active duty military population.

  7. Alteration and mineralization in the eastern part of the Soldier Mountains, Camas County, Idaho

    Lewis, Reed S.

    2001-01-01

    The eastern part of the Soldier Mountains in Camas County, south-central Idaho, is underlain principally by plutonic rocks of Cretaceous and Eocene age that locally have undergone propylitic, potassic, and muscovite-quartz alteration. Muscovite- quartz alteration is Cretaceous in age and is localized along joints and fractures, some of which are filled with quartz. Associated veins have yielded minor amounts of gold. Potassic alteration is probably both Cretaceous and Eocene in age but is weakly developed and limited in extent. Propylitic alteration is Eocene in age and is pronounced around biotite granite plutons. Despite a clear association between plutons of biotite granite and widespread propylitic alteration, mineralization associated with these rocks was minimal. Mineralized areas within more mafic Eocene plutons are characterized by veins and (or) stockworks(?) enriched in copper, molybdenum, and silver, but these areas are restricted in size and have not been productive.

  8. Recent eolian activity and paleoclimate fluctuations in the Ferris Lost Soldier Area, South-Central Wyoming

    The Ferris Dune Fields were examined. Sand dunes are especially valuable in paleoclimate reconstructions because they: (1) bury and preserve datable materials and artifacts; (2) respond to even subtle changes in wind velocity and direction as reflected both in external morphology and internal structures; and (3) remain unconsolidated, making them amenable to easy textural and compositional examination. The valley of Clear Creek in the Ferris Dunes reveals a relatively continuous Holocene section of interbedded dune and interdunal pond deposits. Radiocarbon dates from the interdunal pond strata at Clear Creek, theoretical sand dune migration rates, compositional analysis of periglacial sand wedges, and relative dating of actively migrating parabolic dunes reveals a general sequence of geologic-climatic events that affected the Ferris-Lost Soldier area. The most recent major reactivaton of dunes occurred approximately 290 years ago.

Methodologically, the paper attends to three general technological developments in the evolution of the U.S. Army uniform: the design of the new Army Combat Uniform (ACU; the technological advances in the uniform, including embedded wearables, biometric identification devices, and 3D combat enhancement systems; and the bio-networking, GPS, and digital communication arrays that physically link digital uniforms to a larger geopolitical network of U.S. military strategy and surveillance. Throughout, the work traces the aforementioned theory of silhouet-ting in relation to select sociopolitical consequences of linking digitally enhanced soldiers into a transnational grid of surveillance.

    2015-01-01

    Thyrotoxic periodic paralysis (TPP) is an endocrine disorder presenting with proximal motor weakness, typically greatest in the lower extremities, hypokalemia, and signs or laboratory findings consistent with hyperthyroidism. The incidence of TPP is highest in Asian males. This is a case report of a 30-year-old male active duty Soldier who presented to the emergency department complaining of several recent episodes of lower extremity paralysis. The patient underwent a workup which included serum and cerebrospinal fluid studies, and was found to be hypokalemic and hyperthyroid. Following consultation with neurology, the patient was admitted to the medicine service and treated for thyrotoxic periodic paralysis with potassium replacement and treatment of his hyperthyroidism. Since achieving a euthyroid state, he has had no recurrences of TPP. This disease should be considered in patients presenting with symmetric motor weakness and hypokalemia, whether or not symptoms of hyperthyroidism are elicited during the review of systems.

    Purpose: The purpose of this study was to analyze the concentration and precise isotopic composition and ratios of four uranium isotopes ( 234 U, 235 U, 236 U, and 238 U) in the urine of United States soldiers deployed in Samawah, Iraq during the second Gulf War. Methods: Seven active duty US soldiers deployed as military police unit 442 presenting with non-specific symptoms of intractable headaches, excessive fatigue, intermittent fevers, musculoskeletal pains, respiratory impairment, affect changes, urinary tract symptoms, and neurological alterations were clinically evaluated. Each soldier signed a consent form to participate in our study. The collection of 24-hour urine samples of each subject was performed under controlled conditions. The urine samples were personally carried to the laboratory of the Institute of Geochemistry, JW Goethe University, Frankfurt, Germany. Each sample was analyzed in duplicate by multicollector inductively coupled plasma ionization mass spectrometry (MC-ICP-MS). Control samples consisting of an internal urine standard were also analyzed by the same procedure. The analytical methodology included pre-concentration of the urine samples using evaporation, oxidation of organic matter, uranium purification by ion-exchange chromatography, and analysis by mass spectrometry. The final analysis of the specimens was performed by using a double-focusing Thermo Finnigan Neptune multicollector ICP-MS equipped with retarding potential quadrupole lens and a secondary electron multiplier for ion counting. Results: The mean concentration of total uranium was 3.6±1.3 ng/L. The average 238 U/ 235 U ratio was 146.2±10.2. The ratio of 238 U/ 235 U, being considered as the single most important parameter in determining the quantitative state of depletion of the natural uranium ratio, demonstrates a significant internal contamination with depleted uranium in four soldiers. The 234 U/ 238 U ratio was 6.5 x 10 -5 ±5.7 x 10 -6 . The 236 U/ 238 U ratio was

    Full Text Available Interest for insect farming is currently growing globally. Conditions in West Africa appear suitable for developing such farming systems that can benefit communities by improving livelihoods, food and feed security or sanitation. In Ghana and Mali, the Black Soldier Fly (Hermetia illucens Linnaeus, 1758 is being produced for waste recycling and animal feed. In a two stages process (egg and larvae production, egg production was hampered by a pupal parasitoid, Dirhinus giffardii Silvestri, 1913 (Hymenoptera: Chalcididae, which reduced future broodstock by almost 72%. This is the first time D. giffardii is reported as a parasitoid of H. illucens pupae and one of the first reports of parasitism in this commercially important fly species. The introduction of precautionary measures is highly recommended for the success of H. illucens production systems in West Africa.

    2008-02-01

    Full Text Available Background:The disk diffusion method for identification of yeasts species was performed based on different but distinct susceptibilities of yeasts spp.to chemicals:janus green, ethidium bromide,2,3,5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6G. Methods: Atotal of 568 Iranian soldiers went under study for isolation and identification of Yeast species from their oral cavity. Asterile swab was used for each individual and specimens were collected from the nasopharynx region, then inoculated to petri dishes containing Sabouraud Dextrose Agar and incubated for 48 hrs at 37 °C. All colonies were counted and stocked in distilled water and stored in a refrigerator for further analysis. The yeasts were identified by the “disk diffusion test” [6,8]. This is a simple, rapid, accurate, and inexpensive technique presented by Sobczak [8]. By this method we identified yeast species within 24-48 hrs. Results: 51.4% of petri dishes were positive for yeast species and 318 strains were identified. Candida albicans, Candida kefyr, Candida tropicalis and Candida guilliermondii were the most common yeast species isolated from the oral cavity of soldiers. Conclusion: We used this method because of its simplicity and other beneficial characteristics for rapid identification of large and numerous isolates and the results were compared with other morphological characters such as chlamydospore and germ tube production. In addition,we used some type strains (Candida parapsilosis: PTCC 5089,Candida tropicalis: PTCC 5028,Saccharomyces cerevisiae:PTCC 5052,Candida lipolytica: PTCC 5063,Candida lipolytica:PTCC 5064,and the results were acceptable.

    There has been a great deal of research on the comorbidity of insomnia and psychiatric disorders, but much of the existing data is based on small samples and does not assess the full diagnostic criteria for each disorder. Further, the exact nature of the relationship between these conditions and their impact on cognitive problems are under-researched in military samples. Data were collected from the All Army Study of the Army Study to Assess Risk and Resilience in Service members (unweighted N = 21, 449; weighted N = 674,335; 18-61 years; 13.5% female). Participants completed the Brief Insomnia Questionnaire to assess for insomnia disorder and a self-administered version of the Composite International Diagnostic Interview Screening Scales to assess for psychiatric disorders and cognitive problems. Military soldiers with current major depressive episode (MDE) had the highest prevalence of insomnia disorder (INS; 85.0%), followed by current generalized anxiety disorder (GAD; 82.6%) and current posttraumatic stress disorder (PTSD; 69.7%), respectively. Significant interactions were found between insomnia and psychiatric disorders; specifically, MDE, PTSD, and GAD status influenced the relationship between insomnia and memory/concentration problems. Cross-sectional nature of the assessment and the absence of a comprehensive neurocognitive battery. Psychiatric disorders moderated the relationship between insomnia and memory/concentration problems, suggesting that psychiatric disorders contribute unique variance to cognitive problems even though they are associated with insomnia disorder. Results highlight the importance of considering both insomnia and psychiatric disorders in the diagnosis and treatment of cognitive deficits in military soldiers. Copyright © 2017 Elsevier B.V.

    Full Text Available Background/Aim. Obesity is currently considered to be the most frequent metabolic disease worldwide, not only in developed but also in developing countries. The aim of this work was to describe the development of health status in soldiers of the Armed Forces of the Czech Republic (ACR and to emphasize the markers of non-communicable diseases. Our study describes the anthropometric and biochemical parameters of a large group of Czech Army professional soldiers. Data were obtained over a period of 11 years. Methods. During the monitored period, from 1999 to 2009, military physicians carried out on the average 6,360 examinations on professional soldiers per year and monitored their health and nutritional status with the aim of preventing the risk factors of non-communicable diseases. These examinations are compulsory for all professional soldiers at the age of 25, 30, 33, and 36 years. From the age of 39, these examinations are carried out every year till the end of their career. Besides taking personal histories and carrying out standard physical examinations, blood was taken for biochemical examination. The following anthropometric parameters were monitored: body constitution using body mass index (BMI and waist circumference. Our study describes only part of the data concerning anthropometric and biochemical parameters of professional soldiers which were obtained over a period of 11 years. Results. Average BMI values in men were in the overweight range (26.5-27 kg/m2. Average values of waist circumference, however, ranged from 91.9 cm to 93.4 cm. Between the first and the last year of monitoring a statistically significant decrease in these values ranging from 93.4 ± 9.8 cm to 92.7 ± 9.5 cm (p < 0.001 was observed. All monitored anthropometric parameters in female professional soldiers were within normal limits. During the monitored period the proportion of overweight men gradually increased from 52% to 57.1% (p < 0.001. There were no

  19. Visual search of Mooney faces

    Directory of Open Access Journals (Sweden)

    Jessica Emeline Goold

    2016-02-01

    Full Text Available Faces spontaneously capture attention. However, which special attributes of a face underlie this effect are unclear. To address this question, we investigate how gist information, specific visual properties and differing amounts of experience with faces affect the time required to detect a face. Three visual search experiments were conducted investigating the rapidness of human observers to detect Mooney face images. Mooney images are two-toned, ambiguous images. They were used in order to have stimuli that maintain gist information but limit low-level image properties. Results from the experiments show: 1 although upright Mooney faces were searched inefficiently, they were detected more rapidly than inverted Mooney face targets, demonstrating the important role of gist information in guiding attention towards a face. 2 Several specific Mooney face identities were searched efficiently while others were not, suggesting the involvement of specific visual properties in face detection. 3 By providing participants with unambiguous gray-scale versions of the Mooney face targets prior to the visual search task, the targets were detected significantly more efficiently, suggesting that prior experience with Mooney faces improves the ability to extract gist information for rapid face detection. However, a week of training with Mooney face categorization did not lead to even more efficient visual search of Mooney face targets. In summary, these results reveal that specific local image properties cannot account for how faces capture attention. On the other hand, gist information alone cannot account for how faces capture attention either. Prior experience facilitates the effect of gist on visual search of faces, making faces a special object category for guiding attention.

    How do we find what we are looking for? A target can be in plain view, but it may be detected only after extensive search. During a search we make directed attentional deployments like saccades to segment the scene until we detect the target. Depending on difficulty, the search may be fast with few attentional deployments or slow with many, shorter deployments. Here we study visual search in barn owls by tracking their overt attentional deployments-that is, their head movements-with a camera. We conducted a low-contrast feature search, a high-contrast orientation conjunction search, and a low-contrast orientation conjunction search, each with set sizes varying from 16 to 64 items. The barn owls were able to learn all of these tasks and showed serial search behavior. In a subsequent step, we analyzed how search behavior of owls changes with search complexity. We compared the search mechanisms in these three serial searches with results from pop-out searches our group had reported earlier. Saccade amplitude shortened and fixation duration increased in difficult searches. Also, in conjunction search saccades were guided toward items with shared target features. These data suggest that during visual search, barn owls utilize mechanisms similar to those that humans use.

    This article explores the role of caregivers in the reintegration of former child soldiers from Sierra Leone. Using data on 282 youth and their respective caregivers, our aim is to focus on the caregiver-child relationship after reintegration. We investigate the extent to which caregivers know about child soldiers' experiences of direct and indirect violence, as well as involvement in war activities. We further examine variables that might shape the degree of caregiver knowledge of child's war experiences. Finally, we examine if caregiver knowledge of war experiences is associated with child's psychosocial outcomes. Findings highlight the importance of developing thoughtful programs that consider the needs of the child in the context of the family and caregivers with whom he or she is reunified.

    2013-09-01

    Search for specific and well defined literature related to subject of interest is the foremost step in research. When we are familiar with topic or subject then we can frame appropriate research question. Appropriate research question is the basis for study objectives and hypothesis. The Internet provides a quick access to an overabundance of the medical literature, in the form of primary, secondary and tertiary literature. It is accessible through journals, databases, dictionaries, textbooks, indexes, and e-journals, thereby allowing access to more varied, individualised, and systematic educational opportunities. Web search engine is a tool designed to search for information on the World Wide Web, which may be in the form of web pages, images, information, and other types of files. Search engines for internet-based search of medical literature include Google, Google scholar, Scirus, Yahoo search engine, etc., and databases include MEDLINE, PubMed, MEDLARS, etc. Several web-libraries (National library Medicine, Cochrane, Web of Science, Medical matrix, Emory libraries) have been developed as meta-sites, providing useful links to health resources globally. A researcher must keep in mind the strengths and limitations of a particular search engine/database while searching for a particular type of data. Knowledge about types of literature, levels of evidence, and detail about features of search engine as available, user interface, ease of access, reputable content, and period of time covered allow their optimal use and maximal utility in the field of medicine. Literature search is a dynamic and interactive process; there is no one way to conduct a search and there are many variables involved. It is suggested that a systematic search of literature that uses available electronic resource effectively, is more likely to produce quality research.

    The purpose of this study was to assess personality traits, psychological fitness, and hardiness among conscript soldiers volunteering for international missions (n = 146), by comparing them with conscripts from the same year class and unit who did not apply for international missions (n = 275). The sample consisted of all mandatory enlisted soldiers assigned to a supply and maintenance regiment. There were no demographic differences between the groups. The volunteers reported greater stress tolerance, concern for others, extraversion, and self-confidence than the non-volunteers. There were no differences between the groups in orderliness, temper instability, or independence. Volunteers repeatedly reported greater psychological fitness for military missions and greater hardiness over the period of military service compared to the non-volunteers.

  12. Design Considerations of a Lower Limb Exoskeleton System to Assist walking and Load-Carrying of Infantry Soldiers

    Directory of Open Access Journals (Sweden)

    Seungnam Yu

    2014-01-01

    Full Text Available This paper describes the development of a wearable exoskeleton system for the lower extremities of infantry soldiers and proposes appropriate design criteria based on existing case studies. Because infantry soldiers carry a variety of equipment, the interference with existing equipment and additional burden of the exoskeleton support system should be minimized. Recent studies have shown that a user only needs to be supported in the gravitational direction when walking on flat terrain; however, active joints are necessary to support walking over rough and sloped terrain such as mountains. Thus, an underactuated exoskeleton system was considered: passive joints are applied to the hip and ankle joints, and active joints are applied to the knee joints to exploit the dynamic coupling effect of the link structure and muscular activation patterns when the user is going up and down stairs. A prototype of the exoskeleton system was developed and validated through a simple stair-climbing experiment.

    2017-05-01

    Few studies demonstrate how the index trauma may influence subsequent post-traumatic stress disorder (PTSD) symptoms, especially among soldiers. There is still no consensus on specific trauma types and their corresponding PTSD symptom profiles. Furthermore, varied PTSD symptom manifestations that may yield to PTSD trauma subtypes are yet to be known. Importantly, the significance of the military culture's possible influence on soldiers' PTSD has also been underexplored. And the dominant PTSD construct may possibly be unable to capture the essential aspects of the military context in understanding combat-related PTSD. Hence, this study aims to reach an understanding into how index trauma and military culture may possibly shape participants' PTSD expressions. Case study design was used, wherein multiple sources of data-such as PTSD assessments, and interviews with the participants and key informants-enabled data triangulation. The three case reports are the outcomes of the corroboration of evidences that reveal an enriched and holistic understanding of the phenomenon under study. The Ethics Review Board Committee of the Armed Forces of the Philippines Medical Center approved the study. The participants were three Filipino active duty combat soldiers. Although all participants had similar index traumas, their PTSD symptom expressions are unique from one another, in that they differ in terms of their most incapacitating PTSD symptoms and other symptoms that have been potentially shaped by military culture. Their most incapacitating symptoms: hypervigilance (case 1), negative belief in oneself and negative emotions (case 2), prolonged distress, and marked physiological reactions to trauma-related cues (case 3), may be understood in the light of how they personally experienced different circumstances of their index traumas. The way participants have anchored specific components of their sworn soldier's creed (i.e., not leaving a fallen comrade) into some of their PTSD

    Large neighborhood search is a metaheuristic that has gained popularity in recent years. The heuristic repeatedly moves from solution to solution by first partially destroying the solution and then repairing it. The best solution observed during this search is presented as the final solution....... This tutorial introduces the large neighborhood search metaheuristic and the variant adaptive large neighborhood search that dynamically tunes parameters of the heuristic while it is running. Both heuristics belong to a broader class of heuristics that are searching a solution space using very large...... neighborhoods. The tutorial also present applications of the adaptive large neighborhood search, mostly related to vehicle routing problems for which the heuristic has been extremely successful. We discuss how the heuristic can be parallelized and thereby take advantage of modern desktop computers...

    Full Text Available Outbreaks of cutaneous leishmaniasis are relatively common among soldiers involved in nocturnal activities in tropical forests. We investigated the population dynamics of sand flies in a military training camp located in a remnant of Atlantic rainforest in northeastern Brazil, where outbreaks of cutaneous leishmaniasis have sporadically been described. From July 2012 to July 2014, light traps were monthly placed in 10 collection sites, being nine sites located near the forest edge and one near a sheep and goat stable. Light traps operated from 5:00 pm to 6:00 am, during four consecutive nights. Leishmania infection in sand flies was assessed using a fast real-time PCR assay. Cases of cutaneous leishmaniasis among soldiers were also investigated. In total, 24,606 sand flies belonging to 25 species were identified. Males (n = 12,683 predominated over females (n = 11,923. Sand flies were present during all months, being more numerous in March (n = 1,691 and April 2013 (n = 3,324. Lutzomyia choti (72.9% was the most abundant species, followed by Lutzomyia longispina (13.8%, Lutzomyia complexa (5.3%, representing together >90% of the sand flies collected. Forty cases of cutaneous leishmaniasis were recorded among soldiers from January 2012 to December 2014. Leishmania isolates were obtained from eight patients and were all characterized as Leishmania braziliensis. Soldiers and anyone overnighting in Atlantic rainforest remnants should adopt preventative measures such as the use of repellents on bare skin or clothes and insecticide-treated tents.

  3. PSYCHOLOGICAL PROBLEMS AND STRESS FACED BY SOLDIERS WHO OPERATE IN ASYMMETRIC WARFARE ENVIRONMENTS: EXPERIENCES IN THE FIELD

    Directory of Open Access Journals (Sweden)

    Giuseppe CAFORIO

    2014-10-01

    Full Text Available This article deals with the problems of anxiety, stress and psychological discomfort that can affect soldiers sent on asymmetric warfare operations. It is based on secondary analysis of the data of two important field researches whose results have recently (2013 been published. Although the two researches adopted different methodologies, the testimonies are fully comparable and show that soldiers from different countries and cultures display common or similar reactions when they are placed in the stress conditions that the asymmetric environment involves. The approach of the paper is drawn up in such a way as to make the reader a participating observer of the reality of such missions. It is therefore centered on the personal testimonies of the soldiers interviewed in the two researches, testimonies reported just as they are, in their simplicity and, often, drama, with comments by the author kept to a minimum in order to give readers ample opportunity to evaluate and interpret the reported texts on their own. The research data, drawn from the declarations of those directly concerned, reveal the existence of a problem of psychological distress resulting from deployment in asymmetric warfare situations that is in part different in the causes of the problems resulting from deployment in traditional combat and affects percentages of participating soldiers that are not high but definitely significant. The highest incidence appears to be constituted by problems relating to reintegration into normal social and working life upon returning from the mission. This is followed in percentage terms by anxiety situations relating to life far from the family, due in large part to a sense of powerlessness for the scant possibility of managing family situations that may have cropped up or already existed beforehand.

    Pre-deployment identification of soldiers at risk for long-term posttraumatic stress psychopathology after home coming is important to guide decisions about deployment. Early post-deployment identification can direct early interventions to those in need and thereby prevents the development of chronic psychopathology. Both hold significant public health benefits given large numbers of deployed soldiers, but has so far not been achieved. Here, we aim to assess the potential for pre- and early post-deployment prediction of resilience or posttraumatic stress development in soldiers by application of machine learning (ML) methods. ML feature selection and prediction algorithms were applied to a prospective cohort of 561 Danish soldiers deployed to Afghanistan in 2009 to identify unique risk indicators and forecast long-term posttraumatic stress responses. Robust pre- and early postdeployment risk indicators were identified, and included individual PTSD symptoms as well as total level of PTSD symptoms, previous trauma and treatment, negative emotions, and thought suppression. The predictive performance of these risk indicators combined was assessed by cross-validation. Together, these indicators forecasted long term posttraumatic stress responses with high accuracy (pre-deployment: AUC = 0.84 (95% CI = 0.81-0.87), post-deployment: AUC = 0.88 (95% CI = 0.85-0.91)). This study utilized a previously collected data set and was therefore not designed to exhaust the potential of ML methods. Further, the study relied solely on self-reported measures. Pre-deployment and early post-deployment identification of risk for long-term posttraumatic psychopathology are feasible and could greatly reduce the public health costs of war.

  10. Delaying information search

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available In three studies, we examined factors that may temporarily attenuate information search. People are generally curious and dislike uncertainty, which typically encourages them to look for relevant information. Despite these strong forces that promote information search, people sometimes deliberately delay obtaining valuable information. We find they may do so when they are concerned that the information might interfere with future pleasurable activities. Interestingly, the decision to search or to postpone searching for information is influenced not only by the value and importance of the information itself but also by well-being maintenance goals related to possible detrimental effects that negative knowledge may have on unrelated future plans.

  12. Optimization of partial search

    International Nuclear Information System (INIS)

    Korepin, Vladimir E

    2005-01-01

    A quantum Grover search algorithm can find a target item in a database faster than any classical algorithm. One can trade accuracy for speed and find a part of the database (a block) containing the target item even faster; this is partial search. A partial search algorithm was recently suggested by Grover and Radhakrishnan. Here we optimize it. Efficiency of the search algorithm is measured by the number of queries to the oracle. The author suggests a new version of the Grover-Radhakrishnan algorithm which uses a minimal number of such queries. The algorithm can run on the same hardware that is used for the usual Grover algorithm. (letter to the editor)

    Problem of registration and search for intermediate vector bosons is discussed. According to weak-current theory there are three intermediate vector bosons with +1(W + )-1(W - ) and zero (Z 0 ) electric charges. It was suggested to conduct the investigation into particles in 1976 by cline, Rubbia and Makintair using proton-antiproton beams. Major difficulties of the experiment are related to the necessity of formation of sufficient amount of antiparticles and the method of antiproton beam ''cooling'' for the purpose of reduction of its random movements. The stochastic method was suggested by van der Meer in 1968 as one of possible cooling methods. Several large detectors were designed for searching intermediate vector bosons

    Most electronic search efforts directed at identifying primary studies for inclusion in systematic reviews rely on the optimal Boolean search features of search interfaces such as DIALOG and Ovid. Our objective is to test the ability of an Ultraseek search engine to rank MEDLINE records of the included studies of Cochrane reviews within the top half of all the records retrieved by the Boolean MEDLINE search used by the reviewers. Collections were created using the MEDLINE bibliographic records of included and excluded studies listed in the review and all records retrieved by the MEDLINE search. Records were converted to individual HTML files. Collections of records were indexed and searched through a statistical search engine, Ultraseek, using review-specific search terms. Our data sources, systematic reviews published in the Cochrane library, were included if they reported using at least one phase of the Cochrane Highly Sensitive Search Strategy (HSSS), provided citations for both included and excluded studies and conducted a meta-analysis using a binary outcome measure. Reviews were selected if they yielded between 1000-6000 records when the MEDLINE search strategy was replicated. Nine Cochrane reviews were included. Included studies within the Cochrane reviews were found within the first 500 retrieved studies more often than would be expected by chance. Across all reviews, recall of included studies into the top 500 was 0.70. There was no statistically significant difference in ranking when comparing included studies with just the subset of excluded studies listed as excluded in the published review. The relevance ranking provided by the search engine was better than expected by chance and shows promise for the preliminary evaluation of large results from Boolean searches. A statistical search engine does not appear to be able to make fine discriminations concerning the relevance of bibliographic records that have been pre-screened by systematic reviewers.

    Full Text Available Objective – Effective literature searching is of paramount importance in supporting evidence based practice, research, and policy. Missed references can have adverse effects on outcomes. This paper reports on the development and evaluation of an online learning resource, designed for librarians and other interested searchers, presenting an evidence based approach to enhancing and testing literature searches. Methods – We developed and evaluated the set of free online learning modules for librarians called Smart Searching, suggesting the use of techniques derived from search filter development undertaken by the CareSearch Palliative Care Knowledge Network and its associated project Flinders Filters. The searching module content has been informed by the processes and principles used in search filter development. The self-paced modules are intended to help librarians and other interested searchers test the effectiveness of their literature searches, provide evidence of search performance that can be used to improve searches, as well as to evaluate and promote searching expertise. Each module covers one of four techniques, or core principles, employed in search filter development: (1 collaboration with subject experts; (2 use of a reference sample set; (3 term identification through frequency analysis; and (4 iterative testing. Evaluation of the resource comprised ongoing monitoring of web analytics to determine factors such as numbers of users and geographic origin; a user survey conducted online elicited qualitative information about the usefulness of the resource. Results – The resource was launched in May 2014. Web analytics show over 6,000 unique users from 101 countries (at 9 August 2015. Responses to the survey (n=50 indicated that 80% would recommend the resource to a colleague. Conclusions – An evidence based approach to searching, derived from search filter development methodology, has been shown to have value as an online learning

    The black soldier fly (Hermetia illucens) is one of the most promising insect species for use in animal feed. However, studies investigating feed and food safety aspects of using black soldier fly as feed are scarce. In this study, we fed black soldier fly larvae feeding media enriched with seaweed, which contains naturally high concentrations of heavy metals and arsenic. The aim of this study was to investigate the potential transfer of such undesirable substances from the feeding media to the larvae. The larvae accumulated cadmium, lead, mercury and arsenic. Concentrations of these elements in the larvae increased when more seaweed was added to the feeding media. The highest retention was seen for cadmium (up to 93%) and the lowest for total arsenic (up to 22%). When seaweed inclusion exceeded 20% in the media, this resulted in larval concentrations of cadmium and total arsenic above the current European Union maximum levels for these elements in complete feed. Our results confirm that insect larvae can accumulate heavy metals and arsenic when present in the feeding media. A broader understanding of the occurrence of these undesirable substances in processed larvae products is needed to assess feed and food safety. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Full Text Available Background/Aim. Millions of soldiers around the world represent one of the most vulnerable populations regarding exposure to human immunodeficiency virus (HIV infection. The programs for HIV prevention remain the most viable approach to reducing the spread of HIV infection. Very few studies have tested the effectiveness of HIV preventive interventions undertaken in military population. The aim of this study was to determine the effectiveness of educational film to transfer knowledge about HIV infection to soldiers. Methods. We performed a quasi-experimental study among 102 soldiers of the Serbian Armed Forces. The experimental intervention consisted of the HIV knowledge pre-questionnaire, watching a film on HIV knowledge, then the post-HIV knowledge questionnaire. The results of pre-and post-HIV knowledge questionnaires were compared. Results. There were 23 questions in the test. The average total score on the questionnaire before watching the film was 18.23 and after watching it was 20.14, which was statistically significant difference (p < 0.001. Conclusions. The results of the study show that viewing a film on HIV infection is an effective method of transferring knowledge about HIV to the Serbian military population.

    Prior studies suggest that people often search insufficiently in sequential-search tasks compared with the predictions of benchmark optimal strategies that maximize expected payoff. However, those studies were mostly conducted in individualist Western cultures; Easterners from collectivist cultures, with their higher susceptibility to escalation of commitment induced by sunk search costs, could exhibit a reversal of this undersearch bias by searching more than optimally, but only when search costs are high. We tested our theory in four experiments. In our pilot experiment, participants generally undersearched when search cost was low, but only Eastern participants oversearched when search cost was high. In Experiments 1 and 2, we obtained evidence for our hypothesized effects via a cultural-priming manipulation on bicultural participants in which we manipulated the language used in the program interface. We obtained further process evidence for our theory in Experiment 3, in which we made sunk costs nonsalient in the search task-as expected, cross-cultural effects were largely mitigated. © The Author(s) 2015.

    Bénichou, O.; Loverdo, C.; Moreau, M.; Voituriez, R.

    2011-01-01

    This review examines intermittent target search strategies, which combine phases of slow motion, allowing the searcher to detect the target, and phases of fast motion during which targets cannot be detected. It is first shown that intermittent search strategies are actually widely observed at various scales. At the macroscopic scale, this is, for example, the case of animals looking for food; at the microscopic scale, intermittent transport patterns are involved in a reaction pathway of DNA-binding proteins as well as in intracellular transport. Second, generic stochastic models are introduced, which show that intermittent strategies are efficient strategies that enable the minimization of search time. This suggests that the intrinsic efficiency of intermittent search strategies could justify their frequent observation in nature. Last, beyond these modeling aspects, it is proposed that intermittent strategies could also be used in a broader context to design and accelerate search processes.

    The identification of modifiable predeployment vulnerability factors that increase the risk of combat stress reactions among soldiers once deployed to a war zone offers significant potential for the prevention of posttraumatic stress disorder (PTSD) and other combat-related stress disorders. Adults with anxiety disorders display heightened emotional reactivity to a single inhalation of 35% carbon dioxide (CO(2)); however, data investigating prospective linkages between emotional reactivity to CO(2) and susceptibility to war-zone stress reactions are lacking. To investigate the association of soldiers' predeployment emotional reactivity to 35% CO(2) challenge with several indices of subsequent war-zone stress symptoms assessed monthly while deployed in Iraq. Prospective cohort study of 158 soldiers with no history of deployment to a war zone were recruited from the Texas Combat Stress Risk Study between April 2, 2007, and August 28, 2009. Multilevel regression models were used to investigate the association between emotional reactivity to 35% CO(2) challenge (assessed before deployment) and soldiers' reported symptoms of general anxiety/stress, PTSD, and depression while deployed to Iraq. Growth curves of PTSD, depression, and general anxiety/stress symptoms showed a significant curvilinear relationship during the 16-month deployment period. War-zone stressors reported in theater were associated with symptoms of general anxiety/stress, PTSD, and depression. Consistent with the prediction, soldiers' emotional reactivity to a single inhalation of 35% CO(2)-enriched air before deployment significantly potentiated the effects of war-zone stressors on the subsequent development of PTSD symptoms and general anxiety/stress symptoms but not on the development of depression, even after accounting for the effects of trait anxiety and the presence of past or current Axis I mental disorders. Soldiers' emotional reactivity to a 35% CO(2) challenge may serve as a vulnerability

  12. User Oriented Trajectory Search for Trip Recommendation

    KAUST Repository

    2012-07-08

    Trajectory sharing and searching have received significant attention in recent years. In this thesis, we propose and investigate the methods to find and recommend the best trajectory to the traveler, and mainly focus on a novel technique named User Oriented Trajectory Search (UOTS) query processing. In contrast to conventional trajectory search by locations (spatial domain only), we consider both spatial and textual domains in the new UOTS query. Given a trajectory data set, the query input contains a set of intended places given by the traveler and a set of textual attributes describing the traveler’s preference. If a trajectory is connecting/close to the specified query locations, and the textual attributes of the trajectory are similar to the traveler’s preference, it will be recommended to the traveler. This type of queries can enable many popular applications such as trip planning and recommendation. There are two challenges in UOTS query processing, (i) how to constrain the searching range in two domains and (ii) how to schedule multiple query sources effectively. To overcome the challenges and answer the UOTS query efficiently, a novel collaborative searching approach is developed. Conceptually, the UOTS query processing is conducted in the spatial and textual domains alternately. A pair of upper and lower bounds are devised to constrain the searching range in two domains. In the meantime, a heuristic searching strategy based on priority ranking is adopted for scheduling the multiple query sources, which can further reduce the searching range and enhance the query efficiency notably. Furthermore, the devised collaborative searching approach can be extended to situations where the query locations are ordered. Extensive experiments are conducted on both real and synthetic trajectory data in road networks. Our approach is verified to be effective in reducing both CPU time and disk I/O time.

    Full Text Available In their web search processes users apply multiple types of search strategies, which consist of different search tactics. This paper identifies eight types of information search strategies with associated cases based on sequences of search tactics during the information search process. Thirty-one participants representing the general public were recruited for this study. Search logs and verbal protocols offered rich data for the identification of different types of search strategies. Based on the findings, the authors further discuss how to enhance web-based information retrieval (IR systems to support each type of search strategy.

In the study of external characters, measurements form a very important component, particularly for identification of species. However, the reliability of the measurements depends on the extent of variability which the structures show within and between colonies. For each individual soldier, the following nine parameters were measured: i length of head; ii width of head at mandibles; iii width of head at the posterolateral ends of antennal carinae; iv maximum width of head; v length of left mandible; vi tooth of left mandible from tip; vii length of pronotum; viii width of pronotum; ix length of postmentum; and x width of postmentum.

    Virtual stress testing (VST) provides a non-invasive estimate of the strength of a healing bone through a biomechanical analysis of a patient's computed tomography (CT) scan. We asked whether VST could improve management of patients who had a tibia fracture treated with external fixation. In a retrospective case-control study of 65 soldier-patients who had tibia fractures treated with an external fixator, we performed VST utilizing CT scans acquired prior to fixator removal. The strength of the healing bone and the amount of tissue damage after application of an overload were computed for various virtual loading cases. Logistic regression identified computed outcomes with the strongest association to clinical events related to nonunion within 2 months after fixator removal. Clinical events (n = 9) were associated with a low tibial strength for compression loading (p fracture patients who can safely resume weight bearing. © 2016 Orthopaedic Research Society.

    Emergent behavior that arises from a mass effect is one of the most striking aspects of collective animal groups. Investigating such behavior would be important in order to understand how individuals interact with their neighbors. Although there are many experiments that have used collective animals to investigate social learning or conflict between individuals and society such as that between a fish and a school, reports on mass effects are rare. In this study, we show that a swarm of soldier crabs could spontaneously enter a water pool, which are usually avoided, by forming densely populated part of a swarm at the edge of the water pool. Moreover, we show that the observed behavior can be explained by the model of collective behavior based on inherent noise that is individuals' different velocities in a directed group. Our results suggest that inherent noise, which is widely seen in collective animals, can contribute to formation and/or maintenance of a swarm and that the dense swarm can enter the pool by means of enhanced inherent noise.

Here, we review the literature on the black soldier fly, Hermetia illucens, which is capable of efficiently converting a wide variety of organic materials, from food waste to manure, into insect biomass. They can be grown and harvested without dedicated facilities and are not pestiferous. Their larvae are 42% crude protein and 29% fat, although they are higher in saturated fats than most insects. They do not concentrate pesticides or mycotoxins. They are already grown and recommended for use as animal feed, but with regional legal restrictions on how this is done. For commercial use in human foods, larvae could potentially be milled and converted into a textured protein with a strong flavor. Their biggest advantage over other insects is their ability to convert waste into food, generating value and closing nutrient loops as they reduce pollution and costs. This general advantage is also their greatest disadvantage, for the social stigmas and legal prohibitions against eating organisms that eat waste are added to extant taboos facing insect consumption.

    Embedded combat medical personnel require accurate and timely biometric data to ensure appropriate life saving measures. Injured warfighter's operating in remote environments require both assessment and monitoring often while still engaged with enemy forces. Small wearable devices that can be placed on injured personnel capable of collecting essential biometric data, including the capacity to remotely deliver collected data in real-time, would allow additional medical monitoring and triage that will greatly help the medic in the battlefield. These new capabilities will provide a force multiplier through remote assessment, increased survivability, and in freeing engaged warfighter's from direct monitoring thus improving combat effectiveness and increasing situational awareness. Key questions around what information does the medic require and how effective it can be relayed to support personnel are at their early stages of development. A low power biometric wearable device capable of reliable electrocardiogram (EKG) rhythm, temperature, pulse, and other vital data collection which can provide real-time remote monitoring are in development for the Soldier.

    The purpose of this project was to use NASA technology to assist the US Army in the assessment of motion sickness and performance of soldiers in the Command and Control Vehicle (C2V). Three different vehicle configurations were tested: oblique, (3 seats at a 20-degree angle from the direction of travel); perpendicular, (3 seats at a 90 degree angle); and 4-forward, (all seats faced forward). In all vehicles, the front seat faced forward. Sixteen men and eight women participated for 15 days: 2 days of classroom instruction; 12 days of field tests in the C2V, and 15 minutes of post-field test performance measures. Conditions for field tests were: an initial Park; four Moves (i.e., travel over a mixed terrain); and four Short-halts following movement. NASA task batteries, mood and symptom scales, and physiological data were collected during field tests. Motion sickness symptoms ranging from slight to severe were reported for all subjects. Conclusions were: (1) there was no difference between vehicle configurations; (2) there was a negative impact on crew performance and health when subjects attended to visual screens during vehicle movement; and (3) symptoms and performance degradation were not mitigated by intermittent short-halts.

    Full Text Available Abstract Background The effectiveness of malaria chemoprophylaxis is limited by the lack of compliance whose determinants are not well known. Methods The compliance with malaria chemoprophylaxis has been estimated and analysed by validated questionnaires administered before and after the short-term missions (about four months in five tropical African countries of 2,093 French soldiers from 19 military companies involved in a prospective cohort study. "Correct compliance" was defined as "no missed doses" of daily drug intake during the entire mission and was analysed using multiple mixed-effect logistic regression model. Results The averaged prevalence rate of correct compliance was 46.2%, ranging from 9.6%to 76.6% according to the companies. Incorrect compliance was significantly associated with eveningness (p = 0.028, a medical history of clinical malaria (p Conclusions The identification of circumstances and profiles of persons at higher risk of lack of compliance would pave the way to specifically targeted strategies aimed to improve compliance with malaria chemoprophylaxis and, therefore, its effectiveness.

    2014-01-01

    Full Text Available Differential search algorithm (DS is a relatively new evolutionary algorithm inspired by the Brownian-like random-walk movement which is used by an organism to migrate. It has been verified to be more effective than ABC, JDE, JADE, SADE, EPSDE, GSA, PSO2011, and CMA-ES. In this paper, we propose four improved solution search algorithms, namely “DS/rand/1,” “DS/rand/2,” “DS/current to rand/1,” and “DS/current to rand/2” to search the new space and enhance the convergence rate for the global optimization problem. In order to verify the performance of different solution search methods, 23 benchmark functions are employed. Experimental results indicate that the proposed algorithm performs better than, or at least comparable to, the original algorithm when considering the quality of the solution obtained. However, these schemes cannot still achieve the best solution for all functions. In order to further enhance the convergence rate and the diversity of the algorithm, a composite differential search algorithm (CDS is proposed in this paper. This new algorithm combines three new proposed search schemes including “DS/rand/1,” “DS/rand/2,” and “DS/current to rand/1” with three control parameters using a random method to generate the offspring. Experiment results show that CDS has a faster convergence rate and better search ability based on the 23 benchmark functions.

Motivated by the fact that during a search branching to the left or right at a node does not necessarily have the same cost, e.g. because of branch prediction schemes, we in this paper study the class of skewed binary search trees....... For all nodes in a skewed binary search tree the ratio between the size of the left subtree and the size of the tree is a fixed constant (a ratio of 1/2 gives perfect balanced trees).

    Experimental searches for the elusive magnetic monopole have extended over 50 years -- ever since Dirac showed that the existence of isolated magnetic charges could account for the observation of quantized electric charge. Early searches for Dirac's monopole were hampered since there was no indication of the expected monopole mass, velocity, or origin in the theory. Consequently, numerous experiments searched more or less blindly for relativistic low mass monopoles in the cosmic rays and in particle collisions at high energy accelerators. In this paper, the author reviews briefly the monopole properties which are relevant for their detection and summarize current experimental efforts using induction, ionization/excitation, and catalysis techniques

    2018-02-01

    People often conduct visual searches in which multiple targets are possible (e.g., medical X-rays can contain multiple abnormalities). In this type of search, observers are more likely to miss a second target after having found a first one (a subsequent search miss). Recent evidence has suggested that this effect may be due to a depletion of cognitive resources from tracking the identities and locations of found targets. Given that tracking moving objects is resource-demanding, would finding a moving target further increase the chances of missing a subsequent one? To address this question, we had participants search for one or more targets hidden among distractors. Subsequent search misses were more likely when the targets and distractors moved throughout the display than when they remained stationary. However, when the found targets were highlighted in a unique color, subsequent search misses were no more likely in moving displays. Together, these results suggest that the effect of movement is likely due to the increased cognitive demands of tracking moving targets. Overall, our findings reveal that activities that involve searching for moving targets (e.g., driving) are more susceptible to subsequent search misses than are those that involve searching for stationary targets (e.g., baggage screening).

    Military service is a crucial period in the lives of young people and during this period soldier facing with multiple psychosocial problems. The present study aimed to explore structural analysis of the relationships between depression, drug abuse, social support and the risk of suicidal ideation among Military Medical University soldiers in Iran. In the present correlational research, a sample of 176 soldiers, from three units, was selected using randomly stratified sampling. Data were collected through the Social Support Questionnaire (SSQ), the Beck Depression Inventory-II (BDI-II), the Beck Scale for Suicide Ideation (BSS) and the Possibility of Drug Abuse Scale (LDAS). Structural equation modeling was used to test the fit of the model, identify direct and indirect effects of the psychosocial correlates. Data were analyzed using the SPSS and AMOS software (Verson22). out of the whole subjects, 28.4% had suicidal ideation and 65.3% had degrees of depression (mild to severe). A significant reverse relationship was observed between social support and suicidal ideation (pdrug abuse and suicidal ideation. The final structural model indicated that 74% of the variance in suicidal ideation was explained by the three examined variables of depression, social support and drug abuse. The overall results showed that the risk of suicidal ideation, depression and drug abuse are relatively significant in Military Medical University soldiers requiring taking serious actions by the authorities and other relevant organizations in order to improve the psychosocial health status of these soldiers.
