    2000-01-01

    The one-man submarine dubbed DeepWorker 2000 sits on the deck of Liberty Star, one of two KSC solid rocket booster recovery ships. The sub is being tested on its ability to duplicate the sometimes hazardous job United Space Alliance (USA) divers perform to recover the expended boosters in the ocean after a launch. The boosters splash down in an impact area about 140 miles east of Jacksonville and after recovery are towed back to KSC for refurbishment by the specially rigged recovery ships. DeepWorker 2000 was built by Nuytco Research Ltd., North Vancouver, British Columbia. It is 8.25 feet long, 5.75 feet high, and weighs 3,800 pounds. USA is a prime contractor to NASA for the Space Shuttle program.

  13. Nutritional recommendations for divers.

    PubMed

    Benardot, Dan; Zimmermann, Wes; Cox, Gregory R; Marks, Saul

    2014-08-01

    Competitive diving involves grace, power, balance, and flexibility, which all require satisfying daily energy and nutrient needs. Divers are short, well-muscled, and lean, giving them a distinct biomechanical advantage. Although little diving-specific nutrition research on performance and health outcomes exists, there is concern that divers are excessively focused on body weight and composition, which may result in reduced dietary intake to achieve desired physique goals. This will result in low energy availability, which may have a negative impact on their power-to-weight ratio and health risks. Evidence is increasing that restrictive dietary practices leading to low energy availability also result in micronutrient deficiencies, premature fatigue, frequent injuries, and poor athletic performance. On the basis of daily training demands, estimated energy requirements for male and female divers are 3,500 kcal and 2,650 kcal, respectively. Divers should consume a diet that provides 3-8 g/kg/day of carbohydrate, with the higher values accommodating growth and development. Total daily protein intake (1.2-1.7 g/kg) should be spread evenly throughout the day in 20 to 30 g amounts and timed appropriately after training sessions. Divers should consume nutrient-dense foods and fluids and, with medical supervision, certain dietary supplements (i.e., calcium and iron) may be advisable. Although sweat loss during indoor training is relatively low, divers should follow appropriate fluid-intake strategies to accommodate anticipated sweat losses in hot and humid outdoor settings. A multidisciplinary sports medicine team should be integral to the daily training environment, and suitable foods and fluids should be made available during prolonged practices and competitions.

    Dysbaric osteonecrosis (DON) is regarded as an occupational disease for caisson workers, commercial, and military divers. Magnetic resonance imaging (MRI) was suggested for the surveillance of military divers for DON. This study aimed to determine the prevalence of DON in Turkish Navy divers. The shoulder, hip, and knee joints of 106 male divers were screened for DON with MRI. A questionnaire was used to obtain information about subjects' medical history and diving experience. The mean age of divers was 34.3 +/- 5.8 yr. The divers had spent an average of 12.1 +/- 6.1 yr at their occupation. The average of total hours of diving was 834 +/- 458 h. The maximum diving depth was 53.0 +/- 18.4 m (175 +/- 61 ft) and the average diving depth was 13.3 +/- 8.4 m (44 +/- 28 ft). MRI examinations of divers did not reveal bone lesions consistent with osteonecrosis. We concluded that the risk of DON is very low for military divers who strictly obey the decompression rules and who undergo periodic medical examination. The use of MRI for routine screening of military divers is not justified.

Although it is a hard shell armored suit, it is a relatively light 400 pounds made of aluminum. Future Newtsuits may be made of carbon fiber composite material that is lighter, yet stronger than steel. It has a constant pressure of one atmosphere meaning the pressure all the way down to the suits 1,000 feet limit will be the same as on the surface. Newtsuit, like a spacesuit, has a self contained backpack breathing system with a duration of 48 hours. It employs a series of patented low friction fluidic joints designed to make underwater motion easier and permit 75 percent; normal human mobility.

    A Cartesian diver can be held suspended in a liquid in which there is a density gradient decreasing from bottom to the top if the density of the diver is between those of the liquid at the top and the bottom. This article adds to a number of Cartesian diver activities published in TPT. In a tall beaker of water, a large amount of sugar is added to the bottom. As the sugar dissolves at the bottom, a density gradient, decreasing from bottom to the top, is set up.

  8. Female professional divers. Similarities and differences between male and female professional divers.

    The aim of the present study was to explore the potential differences between female and male professional divers with regards to demographics, diving certificates, areas of diving, diving activity and health effects. The Norwegian Labour Inspection Authority's Diving certificate register contains data on all professional inshore divers who have held a certificate at any time since 1980. Forty nine per cent of these divers responded to the "Norwegian diver 2011" questionnaire. Of these divers 64 female and 1327 male divers completed the questionnaire about their professional diving career, certificate, year of onset and the year they stopped diving professionally if they were not still active in the diving industry. The level of general education was higher among female divers. More males than females were fully certified in diving. The mean age was lower among female than male fully certified divers. Fully certified female divers reported a lower total number of dives, shallower dives and diving for a shorter period of time than the male divers. They also had a lower percentage of work within the quay/construction sector and more often worked as teachers/instructors. A lower percentage of fully certified females than males had experienced decompression sickness (16.7% vs. 26.9%). Life-threatening events and psychologically challenging events were less common among females, as were adverse health effects. No such gender differences were seen for divers with a restricted certificate. The fully certified, female professional divers in our study had a very short diving career, reported fewer and shallower dives, and chose less physically demanding jobs than their male counterparts. They also had a higher level of education, reported less health problems and a better quality of life. The health effects seem to be related to the type of work rather than to gender.

  12. Monitoring diver kinematics with dielectric elastomer sensors

    NASA Astrophysics Data System (ADS)

    Walker, Christopher R.; Anderson, Iain A.

    2017-04-01

    Diving, initially motivated for food purposes, is crucial to the oil and gas industry, search and rescue, and is even done recreationally by millions of people. There is a growing need however, to monitor the health and activity of divers. The Divers Alert Network has reported on average 90 fatalities per year since 1980. Furthermore an estimated 1000 divers require recompression treatment for dive-related injuries every year. One means of monitoring diver activity is to integrate strain sensors into a wetsuit. This would provide kinematic information on the diver potentially improving buoyancy control assessment, providing a platform for gesture communication, detecting panic attacks and monitoring diver fatigue. To explore diver kinematic monitoring we have coupled dielectric elastomer sensors to a wetsuit worn by the pilot of a human-powered wet submarine. This provided a unique platform to test the performance and accuracy of dielectric elastomer strain sensors in an underwater application. The aim of this study was to assess the ability of strain sensors to monitor the kinematics of a diver. This study was in collaboration with the University of Auckland's human-powered submarine team, Team Taniwha. The pilot, completely encapsulated in a hull, pedals to propel the submarine forward. Therefore this study focused on leg motion as that is the primary motion of the submarine pilot. Four carbon-filled silicone dielectric elastomer sensors were fabricated and coupled to the pilot's wetsuit. The first two sensors were attached over the knee joints, with the remaining two attached between the pelvis and thigh. The goal was to accurately measure leg joint angles thereby determining the position of each leg relative to the hip. A floating data acquisition unit monitored the sensors and transmitted data packets to a nearby computer for real-time processing. A GoPro Hero 4 silver edition was used to capture the experiments and provide a means of post-validation. The

  15. The evolution of scuba divers pulmonary edema.

    PubMed

    Edmonds, Carl

    2016-01-01

    The evolution of scuba divers pulmonary edema is described. When discovered in 1981, it was believed to be a cold-induced response in a submerged, otherwise healthy, scuba diver. The clinical features are described and discussed, as are the demographics. An alleged prevalence of 1.1% was complicated by problematic statistics and an apparent increase in reported cases. Recurrences both while diving and swimming or snorkeling were common. More recent case reports and surveys are described, identifying predisposing factors and associations, including cardiac pathology. Stress cardiomyopathies, reversible myocardial disorder or Takotsubo cardiomyopathy, may complicate the presentation, especially in older females. Relevant cardiac investigations and autopsy findings are reviewed. Disease severity and potential lethality of scuba divers pulmonary edema became more apparent early this century, and these influence our current recommendations to survivors. First aid and treatment are also discussed.

    The Mars Museum Visualization Alliance is a collaborative effort funded by the Mars Public Engagement Office and supported by JPL's Informal Education staff and the Solar System Visualization Project to share the adventure of exploration and make Mars a real place. The effort started in 2002 with a small working group of museum professionals to learn how best to serve museum audiences through informal science educators. By the time the Mars Exploration Rovers landed on Mars in January 2004, over 100 organizations were partners in the Alliance, which has become a focused community of Mars educators. The Alliance provides guaranteed access to images, information, news, and resources for use by the informal science educators with their students, educators, and public audiences. Thousands of people have shared the adventure of exploring Mars and now see it as a real place through the efforts of the Mars Museum Visualization Alliance partners. The Alliance has been lauded for "providing just the right inside track for museums to do what they do best," be that webcasts, live presentations with the latest images and information, high-definition productions, planetarium shows, or hands-on educational activities. The Alliance is extending its mission component with Cassini, Genesis, Deep Impact, and Stardust. The Mars Exploration and Cassini Programs, as well as the Genesis, Deep Impact, and Stardust Projects, are managed for NASA by the Jet Propulsion Laboratory, California Institute of Technology, Pasadena, California.

    Alliance-focused training (AFT) aims to increase therapists' ability to recognize, tolerate, and negotiate alliance ruptures by increasing the therapeutic skills of self-awareness, affect regulation, and interpersonal sensitivity. In AFT, therapists are encouraged to draw on these skills when metacommunicating about ruptures with patients. In this article, we present the 3 main supervisory tasks of AFT: videotape analysis of rupture moments, awareness-oriented role-plays, and mindfulness training. We describe the theoretical and empirical support for each supervisory task, provide examples based on actual supervision sessions, and present feedback about the usefulness of the techniques from trainees in our program. We also note some of the challenges involved in conducting AFT and the importance of maintaining a strong supervisory alliance when using this training approach.

  3. Quantifying Relative Diver Effects in Underwater Visual Censuses

    PubMed Central

    Dickens, Luke C.; Goatley, Christopher H. R.; Tanner, Jennifer K.; Bellwood, David R.

    2011-01-01

    Diver-based Underwater Visual Censuses (UVCs), particularly transect-based surveys, are key tools in the study of coral reef fish ecology. These techniques, however, have inherent problems that make it difficult to collect accurate numerical data. One of these problems is the diver effect (defined as the reaction of fish to a diver). Although widely recognised, its effects have yet to be quantified and the extent of taxonomic variation remains to be determined. We therefore examined relative diver effects on a reef fish assemblage on the Great Barrier Reef. Using common UVC methods, the recorded abundance of seven reef fish groups were significantly affected by the ongoing presence of SCUBA divers. Overall, the diver effect resulted in a 52% decrease in the mean number of individuals recorded, with declines of up to 70% in individual families. Although the diver effect appears to be a significant problem, UVCs remain a useful approach for quantifying spatial and temporal variation in relative fish abundances, especially if using methods that minimise the exposure of fishes to divers. Fixed distance transects using tapes or lines deployed by a second diver (or GPS-calibrated timed swims) would appear to maximise fish counts and minimise diver effects. PMID:21533039

    Pulmonary function was measured in 152 professional saturation divers and in a matched control group of 106 subjects. Static lung volumes, dynamic lung volumes and flows, transfer factor for carbon monoxide (T1CO), transfer volume per unit alveolar volume (KCO), delta-N2, and closing volume (CV) were measured and compared with reference values from recent Scandinavian studies, British submariners, and the European Community for Coal and Steel (ECCS) recommended reference values. Diving exposure was assessed as years of diving experience, total number of days in saturation and depth, and as the product of days in saturation and mean depth. Divers had significantly lower values for forced expired volume in one second (FEV1), FEV1/forced vital capacity (FVC) ratio, FEF25-75%, FEF75-85%, FEF50%, FEF75%, T1CO, and KCO compared with the controls and a significantly higher CV. There was a positive correlation between diving exposure and CV, whereas the other variables had negative correlations with diving exposure. Values for the control group were not different from the predictive values of Scandinavian reference studies or British submariners, although the ECCS standard predicted significantly lower values for the lung function variables both in divers and the control group. The pattern of the differences in lung function variables between the divers and controls is consistent with small airways dysfunction and with the transient changes in lung function found immediately after a single saturation dive. The association between reduced pulmonary function and previous diving exposure further indicates the presence of cumulative long term effects of diving on pulmonary function. PMID:2393630

  7. Haptic interface enhancements for Navy divers

    NASA Astrophysics Data System (ADS)

    Rupert, Angus H.; McTrusty, Tim J.; Peak, Joel

    1999-07-01

    Terrestrial orientation and navigation information is provided by three or more redundant, concordant, veridical, and independent sources of sensory information: the skin- muscle-joint somatosensory system, the inner ear vestibular apparatus, and the visual system. The frequent absence of contact with the bottom and the buoyancy provided by water render the skin-muscle-joint system ineffectual as a reliable source of sensory information. A novel deice, utilizing the intuitive nature of the tactile/haptic system, has been developed to enhance the orientation performance of personnel in sensory deprived underwater environments. The tactile situation awareness system (TSAS) consists of senors providing orientation, guidance, and or communication information to a collection of electromechanical stimulators held in close contact with the skin. In preliminary test, divers equipped with TSAS or traditional visual displays swam a triangular course to evaluate the possible benefits of tactile displays for use in the very shallow water diving environments. The TSAS permitted divers to navigate more accurately and offered information at a lower level of cognitive effort, thereby permitting divers to devote more attention to essential mission-related tasks.

  8. IR diver vision for turbidity mitigation

    NASA Astrophysics Data System (ADS)

    Milam, Jerry A.

    2010-04-01

    Commercial, forensic, and military divers often encounter turbid conditions which reduce visibility to zero. Under such conditions, work must be performed completely blind. The darkness resulting from high levels of turbidity is complete, and can be dangerous as well as disorienting. Such darkness can even occur near the surface on a bright and sunny day. Artificial underwater lighting is of no use in such situations, as it only makes matters worse (similar to the use of high beam headlights in dense fog). Certain wavelengths of infrared (IR) light have the ability to penetrate this underwater "fog," and thus form the basis of the current development. Turbidity results from clay, silt, finely divided organic and inorganic matter, soluble colored organic compounds, plankton and microscopic organisms suspended in water. The IR Diver Vision system described herein consists of a standard commercial diving mask of any of several configurations whereby an IR light source, IR video camera, video display, and power source may be integrated within or attached to the mask. The IR light source wavelength is compatible with the spectral bandwidth of the video camera. The camera field-of-view (FOV) is matched to the video display in order to provide a unity magnification and hence prevent diver ocular fatigue. The IR video camera, video display, power source and controls are compatible with extended use in a submarine environment. Some such masks will incorporate tilt/heading sensors and video indicators. 3-D Imaging, Inc. has developed prototypes and has patents pending on such devices.

    2016-11-01

    Sudden sensorineural hearing loss in divers may be caused by either inner-ear barotrauma or inner-ear decompression sickness. There is no consensus on the best treatment option. This study aimed to evaluate the therapeutic value of hyperbaric oxygen therapy for sudden sensorineural hearing loss in divers. A literature review and three cases of divers with sudden sensorineural hearing loss treated with hyperbaric oxygen therapy are presented. Hyperbaric oxygen therapy resulted in hearing improvement in 80 per cent of patients: 39 per cent had hearing improvement and 41 per cent had full recovery. Hyperbaric oxygen therapy improved hearing in divers with sudden sensorineural hearing loss.

    The results of a systematic radiological study of the shoulders and hips of 105 naval divers are reported and compared with those of recorded during a comparative study carried out in non-diver control subjects of a similar age. Almost half the divers had small bone lesions such as dense islets or bordered geodes. These appeared more frequently in divers than in the controls. Their precise natur remains hypothetical, in the absence of histological criteria, but it is possible at least for the bordered geodes, that they represent tiny centres of osteonecrosis.

    2003-11-01

    We investigated the eustachian tube function and the incidence of alternobaric vertigo (AV) in 29 sport self-contained underwater breathing apparatus (SCUBA) divers with, or without, some possible risk factors for AV. The divers had normal audiological and otoscopic findings at the pre-dive examination. We used the nine-step inflation/deflation tympanometric test and Toynbee test for evaluation of eustachian tube function, and the Valsalva manoeuvre for patency. Information on divers, their history, and their otolaryngologic examination were obtained in the pre-dive examination. Divers performed 1086 dives (mean 37, range: 3-100) during the observation period. Four divers (14 per cent) experienced AV during five dives (0.46 per cent), (one diver experienced AV two times). It was found that having an otitis media history or eustachian tube dysfunction determined with the nine-step inflation/deflation tympanometric test before diving, or difficulty in clearing ears during diving could be important risk factors for AV in sport SCUBA divers (p <.05). Divers with such findings seem to be more prone to AV and should pay rigorous attention to the precautions for prevention of AV.

    1994-01-01

    To assess the significance of exposure of divers to waterborne pathogens, specific immunoglobulin G serum antibody responses to Pseudomonas and Aeromonas isolates recovered from dive sites from the respiratory tracts of nine experienced divers and seven diving trainees working in the Chesapeake Bay area over a 6- to 18-month period were measured. A significant increase in the frequency of isolation of these organisms from respiratory surfaces both groups of divers after each dive was noted, with the divers' ears being the predominant recovery site (48%; P < 10(-8), chi-square). The acute serum responses of the majority of experienced divers (83%) showed evidence of preexisting antibody to these potential pathogens, whereas the acute serum response of only 32% of naive divers showed such evidence (P < 10(-8), chi-square). Six months into their training, the rate of seroresponse of the trainees to organisms recovered after their first dives increased to 61% (P = 0.003, chi-square), suggesting that repeated exposure in necessary for generation of a specific systemic immunologic response. The rate of acquisition of a new seroresponse to recovered organisms was approximately 12% per dive for both groups of divers, suggesting that there is continuous exposure to, and infection with, new strains present in the water during dives. These data suggest that, in cases in which systemic antibody is important for protection, there are various levels of susceptibility to waterborne potential pathogens in both experienced and inexperienced divers.

  17. A suspended dive-net technique for catching territorial divers

    Uher-Koch, Brian D.; Rizzolo, Daniel; Wright, Kenneth G.; Schmutz, Joel A.

    2016-01-01

    A variety of methods such as night-lighting and lift nets have been used to catch divers (Gavidae), although 24-hour daylight in the Arctic summer and the remote nature of field sites can make the use of these traditional methods impossible. Our research required capture of adult divers at remote locations in northern Alaska. Here we describe a suspended dive-net technique that we used to safely capture territorial White-billed Gavia adamsii and Pacific Divers G. pacifica and that is lightweight and easy to set up. We also were able to capture divers with chicks, and failed breeders, and suggest that this method could be used to catch other territorial aquatic diving birds, especially other diver species.

  18. Use of handheld sonar to locate a missing diver.

    The purpose of this study was to investigate whether a handheld sonar device significantly reduces the mean time needed to locate a missing diver. This institutional review board approved, prospective, crossover study used a voluntary convenience sample of 10 scuba divers. Participants conducted both a standard and modified search to locate a simulated missing diver. The standard search utilized a conventional search pattern starting at the point where the missing diver (simulated) was last seen. The modified search used a sonar beacon to augment the search. For each search method, successful completion of the search was defined as locating the missing diver within 40 minutes. Twenty total dives were completed. Using a standard search pattern, the missing diver was found by only 1 diver (10%), taking 18 minutes and 45 seconds. In the sonar-assisted search group, the missing diver was found by all 10 participants (100%), taking an average of 2 minutes and 47 seconds (SD 1 minute, 20 seconds). Using the nonparametric related samples Wilcoxon signed rank test, actual times between the sonar group and the standard group were significant (P < .01). Using paired samples t tests, the sonar group's self-assessed confidence increased significantly after using the sonar (P < .001), whereas the standard group decreased in confidence (not statistically significant, P = .111). Handheld sonar significantly reduces the mean duration to locate a missing diver as well as increasing users' confidence in their ability to find a missing diver when compared with standard search techniques.

    Strategic alliances in product development and marketing are crucial to the biotechnology industry. Many alliances, however, are terminated before the drug reaches the market. In this article we make the case that strategic alliances can fail because of how they are negotiated. Alliance contracts are often inflexible and do not allow for changes in market conditions. We propose a model for contract valuation that can assist biotech and/or pharma deal makers in negotiating alliances that have a higher chance of survival in uncertain market conditions. The model makes use of variable royalties and milestone payments. Because licensing is key to the biotech and/or pharma business model this article will be of interest not only to professionals in licensing, but to all professionals active in the industry.

    There is some concern that over a period of years, diving may produce cumulative neurological injury even in divers who have no history of decompression sickness. We evaluated asymptomatic divers and controls for cerebral white-matter lesions using magnetic resonance imaging (MRI). The study enrolled 113 male military divers (34.4 +/- 5.6 yr) and 65 non-diving men (33.1 +/- 9.0 yr) in good health. Exclusion criteria included any condition that might be expected to produce neurological effects. Patent foramen ovale was not assessed. A questionnaire was used to elicit diving history. A 1.5-T MRI device was used to acquire T1, T2-weighted, and fluid attenuated inversion recovery (FLAIR) images of the brain. A lesion was counted if it appeared hyperintense on both T2-weighted and FLAIR images. MRI revealed brain lesions in 26 of 113 divers (23%) and in 7 of 65 (11%) controls, a difference that was statistically significant. There was no significant difference between the groups with respect to blood pressure, smoking history, or alcohol consumption, and no subject reported a history of head trauma or migraine. There was no relationship between MRI findings and age, diving history, or lipid profile in divers. The higher incidence of lesions in the cerebral white matter of divers confirms the possibility that cumulative, subclinical injury to the neurological system may affect the long-term health of military and recreational divers.

  5. A Framework for Managing Diver Impacts on Historic Shipwrecks

    NASA Astrophysics Data System (ADS)

    Edney, Joanne

    2016-12-01

    Shipwrecks are becoming increasingly popular and, therefore important attractions for recreational scuba divers. Divers' usage of these sites has the potential to create a range of adverse impacts on their cultural heritage values. Impacts associated with recreational scuba diving include boat anchor and mooring damage, impairment of site integrity and stability, the effects of intentional and unintentional contact with shipwrecks and artifacts, as well as divers' exhaled air bubbles coming into contact with shipwrecks. While these consequences may not present a major threat in comparison to other human impacts, such as fishing activities, extractive industries or commercial salvage, their cumulative effect can be significant, particularly at sites where visitation levels are high. Unlike natural events such as storms, diver impacts can be controlled and managing these impacts is an important component of a heritage management strategy for any site. Heritage managers face the difficult challenge of, on the one hand, balancing divers' access to important underwater cultural heritage sites, and on the other hand, protecting these sites. This paper outlines the causes and nature of potential recreational diver impacts on shipwrecks, briefly describing a range of management approaches that can mitigate such impacts, and presents a framework for the management of diver impacts on cultural heritage values of historic shipwrecks. The framework is designed to assist managers in deciding on appropriate management actions and priorities for particular sites.

  6. Underwater Acoustic Source Localisation Among Blind and Sighted Scuba Divers

    PubMed Central

    Cambi, Jacopo; Livi, Ludovica; Livi, Walter

    2017-01-01

    Objectives Many blind individuals demonstrate enhanced auditory spatial discrimination or localisation of sound sources in comparison to sighted subjects. However, this hypothesis has not yet been confirmed with regards to underwater spatial localisation. This study therefore aimed to investigate underwater acoustic source localisation among blind and sighted scuba divers. Methods This study took place between February and June 2015 in Elba, Italy, and involved two experimental groups of divers with either acquired (n = 20) or congenital (n = 10) blindness and a control group of 30 sighted divers. Each subject took part in five attempts at an under-water acoustic source localisation task, in which the divers were requested to swim to the source of a sound originating from one of 24 potential locations. The control group had their sight obscured during the task. Results The congenitally blind divers demonstrated significantly better underwater sound localisation compared to the control group or those with acquired blindness (P = 0.0007). In addition, there was a significant correlation between years of blindness and underwater sound localisation (P <0.0001). Conclusion Congenital blindness was found to positively affect the ability of a diver to recognise the source of a sound in an underwater environment. As the correct localisation of sounds underwater may help individuals to avoid imminent danger, divers should perform sound localisation tests during training sessions. PMID:28690888

  7. Assessing the Value of Recreational Divers for Censusing Elasmobranchs

    PubMed Central

    Ward-Paige, Christine A.; Lotze, Heike K.

    2011-01-01

    Background Around the world, researchers are using the observations and experiences of citizens to describe patterns in animal populations. This data is often collected via ongoing sampling or by synthesizing past experiences. Since elasmobranchs are relatively rare, obtaining data for broad-scale trend analysis requires high sampling effort. Elasmobranchs are also relatively large and conspicuous and therefore it may be possible to enlist recreational divers to collect data on their occurrence and relative abundance from daily dive activities. For this, however, a good understanding of the value of data collected by recreational divers is essential. Methodology/Principal Findings Here, we explore the value of recreational divers for censusing elasmobranchs using a diverse set of data sources. First, we use a simulation experiment to explore detection rates of the roving diver technique, used by recreational divers, across a range of fish densities and speeds. Next, using a field survey, we show that inexperienced recreational divers detect and count elasmobranchs as well as experienced recreational divers. Finally, we use semi-structured interviews of recreational dive instructors to demonstrate the value of their recollections in terms of effort and their descriptions of spatial and temporal distributions of sharks in Thailand. Conclusions/Significance Overall, this study provides initial ground-work for using recreational divers for monitoring elasmobranch populations. If used appropriately, citizen-collected data may provide additional information that can be used to complement more standardized surveys and to describe population trends across a range of spatial and temporal scales. Due to the non-extractive nature of this data, recreational divers may also provide important insight into the success of conservation initiatives, such as shark sanctuaries and no-take zones.

    The Research Data Alliance (RDA) is an international organization created in 2012 to provide researchers with a forum for identifying and removing barriers to data sharing. Since then, RDA has gained over 3000 individual members, over three dozen organizational members, 47 Interest Groups, and 17 Working Groups, all focused on research data sharing. Interoperability is one instantiation of data sharing, but is not the only barrier to overcome. Technology limitations, discipline-specific cultures that do not support sharing, lack of best-practices, or lack of good definitions, are only three of a long list of situations preventing researchers from sharing their data. This presentation will cover how RDA has grown, some details on how the first eight solutions contribute to interoperability and sharing, and a sneak peek at what's in the pipeline.

    Diving-related activities may constitute a major threat to coral reefs. This study aimed to quantify the impact of diving in Hong Kong on hard corals and understand how socio-economic characteristics and experience level of divers influence diver-inflicted damage. We recorded and analysed the underwater behaviour of 81 recreational divers. On average, a diver was in contact with marine biota 14.7 times with about 40% of contacts involved corals and 38% were damaging contacts with corals or other biota in a single dive. The most harm-inflicting groups included inexperienced and camera-carrying divers. Although Hong Kong divers did not make many damaging contacts with corals, there is still an imminent need to determine the scale of damage from diving activities on the marine ecosystem given the rapid development of marine-based tourism and the limited coral-inhabited areas in Hong Kong where the marine environment is already under stress from anthropogenic activities.

  13. A calculating alliance.

    PubMed

    Alanis, M; Sippel, S

    1999-01-01

    This article discusses the effects of the alliance between the Church and the Argentine state on women's reproductive rights. Several commentators have criticized how President Carlos Menem used the campaign against abortion for his own political interest. He issued a presidential decree on antiabortion campaign--the Day of the Unborn Child. This decree was announced on December 8, 1998, and the day of observance is March 25 of every coming year. Although the Argentine government does not have a law that explicitly regulates family planning method for the last two decades, many Argentines find the action of the president selfish. The initiation of this presidential decree was the culmination of Menem's manipulation of church and state to secure clerical support for his political regime. Even if statistics is providing him with data concerning the effects of unclear reproductive health laws, he and the church still has chosen not to focus on reproductive rights exclusively, but have concerned themselves primarily with other social and economic issues. While Menem uses the Vatican's pro-life rhetoric and his presidential power to protect fetal life, Argentines will have to contend with the existing Menem policies, which compromise the health of women and children.

    We present a case of a diver who suffered decompression sickness (DCS), but who also was a strict vegetarian for more than 10 years. He presented with symptoms of tingling of both feet and left hand, weakness in both legs and sensory deficits for vibration and propriocepsis after two deep dives with decompression. The initial clinical features of this case were most consistent with DCS, possibly because of a vulnerable spinal cord due to cobalamin deficiency neuropathy. This case illustrates the similarities between DCS and a clinically defined vitamin B12 deficiency. The pathophysiology of vitamin B12 deficiency and common pathology and symptoms of DCS are reviewed.

  15. Exercising divers' thermal protection as a function of water temperature.

    PubMed

    Pendergast, David R; Mollendorf, Joseph

    2011-01-01

    Physiological adjustments and passive thermal insulation are not sufficient to protect divers in the cold and warm waters experienced by sport, professional and military divers. In a previous study of resting subjects, divers were protected by actively heated/cooled water that perfused a six-zone (head, torso, arms, hands, legs and feet) tube suit. Subsequently a self-contained diver thermal protection system (DTPS) was developed and used in this study to test male divers (n = 8) wearing a 6-mm foam neoprene wetsuit in water temperatures (T(W)) of 10 degrees C-39 degrees C at 4 feet in depth. The DTPS is a scuba backpack containing five thermoelectric devices that heat/cool water to 30 degrees C, six pumps that circulate the water through a six-zone tube suit via two manifolds, and an electronic controller. Skin temperatures (T(S), n = 17) and core temperature (T(C), capsule) were measured. The DTPS and each zone of the tube suit were also instrumented. Divers were tested with the DTPS operational (protected) and turned off (unprotected) for 90 minutes. In the unprotected condition, T(S) decreased and approached T(W), while T(C) trended to decrease over the exposure time. Mean T(S) as a function of T(W) was T(S) = 0.44 T(W) + 21.23 degrees C while unprotected, but T(S) = 0.19 T(W) + 27.1 degrees C when the diver was protected. The average total heating/cooling power required to protect the diver was 166 +/- 78W, 86 +/- 95W, 9 +/- 75W, 72 +/- 45W, 135 +/- 73W, 279 +/- 87W and 336 +/- 95W at 10, 15, 20, 25, 30, 35 and 39 degrees C water temperatures, respectively. This power requirement was nominally split 4%, 22%, 22%, 14%, 25% and 13% for head, torso, arms, hands, legs and feet, respectively. While unprotected, divers T(S) and T(C) did not remain within acceptable limits in T(W) below 25 degrees C or above 30 degrees C. When using the DTPS, however, they did remain within acceptable limits, and the divers reported they were comfortable.

    A 2004 McKinsey survey of more than 30 companies reveals that at least 70% of them have major alliances that are underperforming and in need of restructuring. Moreover, JVs that broaden or otherwise adjust their scope have a 79% success rate, versus 33% for ventures that remain essentially unchanged. Yet most firms don't routinely evaluate the need to overhaul their alliances or intervene to correct performance problems. That means corporations are missing huge opportunities: By revamping just one large alliance, a company can generate 100 million dololars to 300 million dollars in extra income a year. Here's how to unlock more value from alliances: (1) Launch the process. Don't wait until your venture is in the middle of a crisis; regularly scan your major alliances to determine which need restructuring. Once you've targeted one, designate a restructuring team and find a senior sponsor to push the process along. Then delineate the scope of the team's work. (2) Diagnose performance. Evaluate the venture on the following performance dimensions: ownership and financials, strategy, operations, governance, and organization and talent. Identify the root causes of the venture's problems, not just the symptoms, and estimate how much each problem is costing the company. (3) Generate restructuring options. Based on the diagnosis, decide whether to fix, grow, or exit the alliance. Assuming the answer is fix or grow, determine whether fundamental or incremental changes are needed, using the five performance dimensions above as a framework. Then assemble three or four packages of restructuring options, test them with shareholders, and gain parents' approval. (4) Execute the changes. Embark on a widespread and consistent communication effort, building support among executives in the JV and the parent companies. So the process stays on track, assign accountability to certain groups or individuals.

    In 2002, The Transplantation Society proposed the creation of a Global Alliance for Transplantation, with the purpose of reducing the existing disparity regarding transplantation activities across the globe. This alliance should include major international scientific societies, international governmental organizations, and pharmaceutical companies. Consultations with each of these parties have taken place during the past 18 months and three Strategic Programs have been initiated: (1) the collection of information on transplantation; (2) the expansion of education in transplantation; and (3) the development of professional guidelines for organ donation and transplantation.

  18. Active diver thermal protection requirements for cold water diving.

    1983-07-01

    An analysis of the supplemental heating requirements for military divers, both surface-tended and free-swimming, is presented. Specific categories of diver heat loss, including respiratory losses and suit convective losses, are characterized over a range of water temperatures, depths, and breathing gas mixtures. The need for a 1-kW diver heater is identified to accommodate deep dives where the limitation of a surface-supplied hot water source and a long hot water umbilical pose an unacceptable burden. A 0.5-kW heater is shown to be satisfactory to extend the performance of existing closed circuit-breathing apparatuses for shallow water operations in water temperatures as low as 40 degrees F. Substantial benefits in heat savings are shown through the use of passive regenerative breath heaters and alternative suit inflation gases for drysuit use.

    Each year in the US three divers, on average, perish inside flooded caves and their remains require recovery. Recovery is a hazardous undertaking often performed by members of the International Underwater Cave Rescue and Recovery (IUCRR) team, in collaboration with local law enforcement and medical examiners/coroners. Since forming in 1999 the IUCRR have established standard recovery procedures for cave diving fatalities. This article reviews each stage of the recovery; the call out, arrival on site, the search, recording/preserving the evidence, the recovery, the handover and post-recovery record-keeping. A series of five cases highlight the challenges IUCRR divers are trained to face. It is strongly recommended local dive teams do not attempt to recover bodies from within flooded caves. IUCRR divers are trained to utilize a uniform procedure that is acceptable to the local law enforcement Incident Command System.

  20. Electrical activity in dental amalgam of submerged divers during welding.

    PubMed

    Ortendahl, T W; Holland, R I

    1987-10-01

    Divers performing underwater manual metal arc welding/cutting (UMMA) have complained about a metallic taste phenomenon. In several dives with voluntary leakage in their diving suits, potential alterations in dental amalgam were registered when they performed UMMA. Polarization resistance values were obtained for the test amalgam cylinders used and the diver's dental restorations. These values, along with the recorded potential values of the amalgam test cylinders and of the diver's dental restorations, enabled us to calculate the depolarizing current, using the law of Ohm. The current depolarizing the amalgam test cylinder did not differ significantly from the mean intermetallic currents between the dental restorations. The clinical effect of intraoral currents when performing UMMA welding should be regarded as small, whereas considerably higher currents should not be ruled out in an intense cutting situation.

  1. Inner-ear decompression sickness in nine trimix recreational divers.

    Recreational technical diving, including the use of helium-based mixes (trimix) and the experimentation of new decompression algorithms, has become increasingly popular. Inner-ear decompression sickness (DCS) can occur as an isolated clinical entity or as part of a multi-organ presentation in this population. Physiological characteristics of the inner ear make it selectively vulnerable to DCS. The inner ear has a slower gas washout than the brain thus potentially making it more vulnerable to deleterious effects of any bubbles that cross a persistent foramen ovale (PFO) and enter the basilar artery, whilst the inner ear remains supersaturated but the brain does not. A questionnaire was made widely available to divers to analyse the incidence of inner-ear DCS after technical dives. One-hundred-and-twenty-six divers submitted completed questionnaires, and we studied each incident in detail. Nine (7.1%) of the 126 responders reported to have had at least one episode of inner-ear DCS, of which seven occurred without having omitted planned decompression stops. Of these seven, four suffered from DCS affecting just the inner ear, while three also had skin, joint and bladder involvement. Five of the nine divers affected were found to have a PFO. All affected divers suffered from vestibular symptoms, while two also reported cochlear symptoms. Three divers reported to have balance problems long after the accident. This small study is consistent with a high prevalence of PFO among divers suffering inner-ear DCS after trimix dives, and the pathophysiological characteristics of the inner ear could contribute to this pathology, as described previously. After an episode of DCS, vestibular and cochlear injury should always be examined for.

  8. On diver thermal status and susceptibility to decompression sickness.

    PubMed

    Gerth, Wayne A

    2015-09-01

    In a recent Letter to the Editor, Clarke, et al, indicated that divers who deliberately chill themselves on a dive to reduce risk of decompression sickness (DCS) may be misinterpreting our 2007 Navy Experimental Diving Unit (NEDU) report. Indeed, we did not advocate that divers should risk hypothermia on bottom to reduce risk of DCS, nor do we dispute the authors' overall admonition to avoid diving cold unnecessarily. However, Clarke, et al, imply more generally that results of our study are not applicable to recreational or technical divers because the dives we tested were atypical of dives undertaken by such divers. We wish to clarify that our study does have implications for recreational and technical divers, implications that should not be ignored. The dives we tested were not intended to be typical of dives undertaken in any actual operational context. Instead, we chose to expose divers to temperatures at the extremes of their thermal tolerance in order to ensure that effects of diver thermal status on DCS susceptibility would be found if such effects existed. Our initial test dive profile provided appreciable time both on bottom and during decompression to allow any differential thermal effects during these two dive phases to manifest, while affording a baseline risk of DCS that could be altered by thermal effects without exposing subjects to inordinately high risks of DCS. Our results strongly indicate that the optimal diver thermal conditions for mitigation of DCS risk or minimization of decompression time entail remaining cool during gas uptake phases of a dive and warm during off-gassing phases. While the dose-response characteristics of our observed thermal effects are almost certainly non-linear in both exposure temperature and duration, it is only reasonable to presume that the effects vary monotonically with these factors. We have no reason to presume that such responses and effects under less extreme conditions would be in directions opposite to

  9. Complex social structure, alliance stability and mating access in a bottlenose dolphin 'super-alliance'.

    PubMed

    Connor, R C; Heithaus, M R; Barre, L M

    2001-02-07

    Large brain size in mammals has been related to the number and complexity of social relationships, particularly social alliances within groups. The largest within-group male alliance known outside of humans is found in a social network (> 400) of Indian Ocean bottlenose dolphins (Tursiops aduncus) in Shark Bay Western Australia. Members of this dolphin 'super-alliance' cooperate against other alliances over access to females. Males within the super-alliance form temporary trios and occasionally pairs in order to consort with individual females. The frequent switching of alliance partners suggests that social relationships among males within the super-alliance might be relatively simple and based on an equivalence rule', thereby allowing dolphins to form large alliances without taxing their 'social intelligence'. The equivalence model predicts that the 14 males in the super-alliance should not exhibit differences in alliance stability or partner preferences. However, data from 100 consortships do not support the equivalence hypothesis. The 14 males exhibited striking differences in alliance stability and partner preferences suggesting that the super-alliance has a complex internal structure. Further, within the super-alliance, alliance stability correlates with consortship rate, suggesting that differentiated relationships within the super-alliance are based on competition for access to females.

    2014-08-01

    The aim was to determine predictors for the development of complaints of temporomandibular disorders (TMD) in a large sample of Dutch scuba divers who were free of any TMD complaints before they started diving actively. Five-hundred and thirty-six scuba divers (mean ± SD age = 40.4 ± 11.9 years; 34.1% women) completed a specifically developed questionnaire, either online or on paper. Stepwise forward logistic regression analysis was performed to predict the presence of TMD pain, with several potential risk factors as predictors. Four hundred and eighty-five of the 536 respondents were free of any TMD pain before they started diving actively. In this sample, TMD pain was present in 214 persons (44.1%). Four predictors contributed significantly to the presence of TMD pain, viz., clenching (OR = 2.466), warm water (OR = 1.685), biting on the mouthpiece (OR = 1.598), and the quality rating of the mouthpiece (OR = 0.887, that is, a higher rating means a smaller odds of having TMD pain). TMD pain is a common complaint among scuba divers who were free of such complaints before they started diving actively. Clenching, biting on the mouthpiece, and a low rating of the mouthpiece are predictors for the presence of TMD pain in scuba divers, while diving in cold water serves as a protective factor for TMD pain.

  16. Identification of bacteria in scuba divers' rinse tanks.

    2010-01-01

    Scuba divers typically rinse equipment in communal tanks. Studies show these tanks are contaminated with bacteria, but the types of bacteria have not been studied. We sought to identify bacteria in rinse tanks at a dive facility at San Pedro, Belize, to determine the origin of the bacteria and determine whether the bacteria represented potential threats to human health. The identity of bacteria was investigated using reverse line blot (RLB) assays based on 28 different rDNA probes designed to detect known pathogens of sepsis, as well as by sequencing 23S rDNA from isolates and performing VITEK identification of several isolates. Based on the identities of bacteria in divers' rinse tanks, many likely originate from the ocean, and others likely originate from the divers themselves. None of the bacteria identified would be considered overt human pathogens. However, some of the bacteria found in the tanks are known to be associated with unsanitary conditions and can cause opportunistic infections, which may pose health problems to some individuals. Rinsing scuba equipment in communal tanks has the potential to transmit disease among some divers. Equipment, especially regulators and masks, should be rinsed/cleaned individually and not be placed in communal tanks.

  17. Commercial diver selection using multiple-criteria decision-making methods.

    2014-01-01

    Personnel selection for different commercial diving jobs is time-consuming and subjective, This paper proposes a combination of two multiple-criteria decision-making (MCDM) methods to provide an objective tool for evaluation according to two main selection criteria: work experience and physical fitness. Subcriteria were computed using the analytic hierarchy process (AHP). By consulting two field professionals, subcriteria for work experience were determined as: working hours on the project type, hand tools, hydraulic tools, pneumatic tools, LP air jet and water lift/dredge, wet bell diving and paramedic training level. Determined by three medical experts, the subcriteria for physical fitness were: age, VO2Max, critical flicker fusion frequency (CFFF), psychomotor performance, and visual and hearing acuities. The pair-wise comparison matrices used to calculate subcriteria weights are filled by the same experts. Eight divers were included in the analysis. The AHP yielded scores of work experience for seven different project types and a physical fitness score for each diver. These scores were used in data envelopment analysis (DEA), to obtain an aggregate ranking of the divers. The methodology was able to differentiate between qualified and unqualified divers. Divers were scored between 0 and 1 for each project type. The overall ranking of divers according to the average of the seven project types' scores was: 1. Diver 7 (1.0000); 2. Diver 5 (0.9486); 3, Diver 8 (0.9453); 4. Diver 2 (0.9421); 5. Diver 3 (0.8441); 6. Diver 4 (0.7804); 7. Diver 6 (0.6554); 8. Diver 1 (0.3931). The proposed methodology allows decision-makers to perform evaluations objectively and systematically, reducing personal conflicts and confusions resulting from subjective immethodical judgments. This methodology is to be applied in real projects to validate the selection criteria and confirm the results.

    2001-01-01

    The goal of this work is to study the relationship between the therapeutic alliance, the subjective perception of improvement, the frequency of sessions and the type of analytic interventions, in both psychoanalysts and non-psychoanalysts patients. 39 subjects under psychoanalytic treatment lasting one to six years (mean 4.2 years) were interviewed. It was performed: a) a therapeutic alliance evaluation scale (HRQ); b) a subjetive improvement perception scale (PSM); c) a scale to evaluate the style of the psychoanalytic interventions (EI). The sample was divided in two groups: 1) 18 non-psychoanalysts under psychoanalytic treatment, who assited to a mean of 1.15 sessions per week (group 1) and b) 21 psychoanalysts receiving two kinds of psychoanalytic treatments: a) one following the international Psychoanalytc Associations rules (group 2A), b) the other with 1.65 mean sessions per week (group 2B). a) patients in groups 1 and 2A showed similar HRQ scores, and both were higher than that shown by group 2B (21.53 vs 21.51 vs 17.22) No differences were found neither in PSM scores (3.61 vs 3.85 vs 3.85 respectively) nor in the EI scores (3.61 vs 3.71 vs 3.71). It was observed a positive correlation between HRQ and PSM (group 1: r: 0.55 and gorup 2, r: 0.31) but no correlation was found neither with the number of sessions per week (group 1, r:0.13; group 2, r: 0.30) nor with EI score (group 1, r: -0.21; group 2, r: 0.08). DISCUSION AND CONCLUSIONS: a) intensity of perceived therapeutic alliance is correlated with improvement but b) is not correlated with sessions frequency or style of psychoanalytic interventions. It is also discussed which psychic changes are related with the therapeutic alliance with regards with different psychoanalytic theoretical frames.

    To analyze the strategic alliances that Catalan hospitals form with other health care entities and other types of institutions to foster technological and organizational innovation. Qualitative case studies were conducted at a sample of 16 public hospitals in Catalonia, Spain. The sample was limited to three (Level 1-3) of Catalonia's four levels of hospitals (classified according to the complexity of the diagnoses and treatments they provide), but Level 4 hospitals were considered as part of the network in the analysis of the alliances. At each hospital, interviews were conducted with the manager, the medical director, and the service director, using a questionnaire that gathered information on strategic alliances with a focus on telemedicine. Qualitative data processing was applied to identify patterns of alliances between hospitals and other institutions. Catalan hospitals interact with other health care agents through three main types of associations: alliances with other hospitals (the most frequent type); alliances with primary care centers (reported mostly by Level 2 hospitals); and alliances with other institutions (e.g., local government, medical companies, and universities). Human resource-sharing (staff mobility) and training were reported most frequently as reasons for creating the alliances. Strategic alliances are formed between hospitals and other health care agents to help improve performance, competitiveness, and services provided to users. These results may help health care system managers promote strategic alliances as a means of optimizing system efficiency without reducing user satisfaction-a key challenge within the context of the current economic situation.

    2012-11-01

    The design of a diving regulator's mouthpiece increases the risk of a temporomandibular disorder (TMD) in scuba divers. The total weight of a diving regulator is reflected directly on the temporomandibular joint, causing articular and periarticular disorders. In the current study, the prevalence of TMD in scuba divers triggered during diving certification training is investigated. We also aimed to determine the factors that lead to TMD during diving training and clarify the observation that there is an increased incidence of TMD in inexperienced divers. The study was held between 2006 and 2011. Ninety-seven divers were referred with the complaint of pain around temporomandibular area. The divers were classified according to their diving experience. Symptoms and signs of TMD were graded. Fourteen divers were diagnosed with TMD. Temporomandibular disorder was seen more frequently in inexperienced divers than in experienced divers (P = 0.0434). The most prevalent symptom was an increased effort for mouthpiece gripping. Temporomandibular joint tenderness and trigger point activation were the mostly seen physical signs. Thirteen divers had an improvement with therapy. The increased effort for stabilizing the mouthpiece is a recognized factor in TMD development. Attention must be paid to an association of scuba diving with TMDs, especially in inexperienced divers having a scuba certification training.

    The purpose of this paper is to outline a course for the training of divers with a special interest in underwater surveying (e.g. surveyors, archaeologists, biologists, geologists, photographers/videographers). This outline presents: i) the Courses' Standards ii) the Learning Objectives for the related Knowledge Development, iii) the Skills that have to be conducted, iv) the Performance Requirements for the students and v) the Open Water Considerations for the Training Dives. It is expected that the resulting course outline will be used as a reference for the training of certified divers who want to become underwater surveyors, providing them basic knowledge and skills to survey adequate data for the detailed documentation of submerged features. Moreover the combination of knowledge (what) and the skills (how) that are presented during the proposed course attempt to define a protocol for the recording of underwater features in favor of mapping and 3D modeling.

    This paper reviews the development of alliances to help develop the Terra Nova oil and gas field in the offshore Atlantic areas of Canada. Largely attributed to BP, the strategic alliance concept got its start in the North Sea and on the North Slope of Alaska. BP saw it as the best way to take advantage of economy-of-scale, mitigate risk, and achieve outsourcing goals while retaining their core competencies. This paper reviews the methods of developing the alliances, the developing of a development plan for the Terra Nova field, and how the alliance plans to maximize the profittability of the operation for all involved.

    We investigated risks for cancer and the case for a cause-effect relationship in five successive cohorts of naval commando divers (n = 682) with prolonged underwater exposures (skin, gastrointestinal tract, and airways) to many toxic compounds in the Kishon River, Israel's most polluted waterway, from 1948 to 1995. Releases of industrial, ship, and agricultural effluents in the river increased substantially, fish yields decreased, and toxic damage to marine organisms increased. Among the divers (16,343 person-years follow-up from 18 years of age to year 2000), the observed/expected ratio for all tumors was 2.29 (p<0.01). Risks increased in cohorts first diving after 1960 compared to risks in earlier cohorts, notably for hematolymphopoietic, central nervous system, gastrointestinal, and skin cancer; induction periods were often brief. The findings suggest that the increases in risk for cancer and short induction periods resulted from direct contact with and absorption of multiple toxic compounds. Early toxic effects in marine life predicted later risks for cancer in divers. PMID:12676624

    1978-09-01

    During a series of three saturation dives to simulated depths of 1000, 1200, and 1400 fsw at the Ocean Simulation Facility, measurements were made to establish the rate of heat loss of unclad divers in helium-oxygen gaseous environments. These measurements were part of a program to determine the dangers of cold stress and the temperature/time relationship tolerated by divers in cold diving bells or in hyperbaric chambers in which environmental conditions are uncontrolled. Three specific gaseous temperatures of 15, 20, and 25 degrees C were considered. In each experiment, as many as four subjects were monitored for body core and mean skin temperature over a 2-h testing period. One or two of the subjects were also monitored for mean body convective heat loss to determine physiological (shell) thermal insulation. Results of these experiments are expressed in depth-time-temperature three-dimensional graphs in whic, the temperature variable is one of the following: mean skin temperature change, mean body temperature change, or mean rectal (core) temperature change, each suitable for defining diver thermal limitations. It was also possible to rank body areas of the subjects in relation to heat loss and temperature decrease during exposure to the cold environment.

    A recreational scuba diver wore a second scuba regulator against his face during a scuba dive, attached by an elastic rubber cord necklace. After surfacing, the diver's left face became swollen. Through a process of elimination all other items of scuba equipment were excluded as potential causes. A dive with the same equipment minus the necklace confirmed the involvement of the necklace in the pathogenesis of the hypersensitive reaction. In vitro ImmunoCap IgE assay was positive to latex (1.30 kUa/L), subsequent patch testing for contact dermatitis provoked a reaction for benzophenone-4, (a UV stabalizer) and Fourier Transform Infra Red spectroscopy identified the elastic as ethylene propylene rubber, containing additional unidentified compounds. Allergy to natural rubber latex occurs in as many as 6% of Americans and Australians. Around three million American residents are thought to scuba dive each year. Recreational divers are, therefore, advised to check such necklaces, which are typically worn around the throat, for frayed ends and exposed rubber filaments.

    Marine protected areas increasingly are challenged to maintain or increase tourism benefits while adequately protecting resources. Although carrying capacity strategies can be used to cope with use-related impacts, there is little understanding of divers themselves, their management preferences, and how preferences relate to conservation goals. By using a stated preference choice modeling approach, we investigated the choices divers make in selecting diving trips to marine protected areas as defined by use level, access, level of supervision, fees, conservation education, and diving expectations. Logit models showed that divers preferred a more restrictive management scenario over the status quo. Divers favored reductions in the level of site use and increased levels of conservation education. Divers did not favor fees to access protected areas, having less access to the resource, or extensive supervision. Finally, divers were much more willing to accept increasingly restrictive management scenarios when they could expect to see increased marine life.

    Postmortem human tissue from recently deceased divers was processed histologically to assess any inner and middle ear damage that could have resulted from the effects of pressure during diving. The following new findings are particularly noteworthy. In one diver, ascent while breath holding resulted in the rupture of the ear drum and blood in the middle ear, in addition to pulmonary barotrauma. In a second diver, following inner ear decompression sickness, new bone growth, similar to that described earlier in experimental studies with the squirrel monkey, was observed in the arms of one of the semicircular canals. These observations are further confirmation that otologic disorders can be a serious threat to divers.

    The International Planetary Data Alliance (IPDA) is an international collaboration of space agencies with a mission of providing access to scientific data returned from solar system missions archived at international data centers. In order to improve access and share scientific data, the IPDA was founded to develop data and software standards. The IPDA has focused on promoting standards that drive common methods for collecting and describing planetary science data. An initial starting point for developing such a standard has been the internationalization of NASA's Planetary Data System (PDS) standard, which has become the de-facto archival data standard. Given the demands of supporting more capable and international missions and collaborations, the Planetary Data System, in partnership with the IPDA, has embarked on developing a next generation data standard and system called PDS4. Significant progress has been made on PDS4 and early adopters are beginning to use the emerging standard on new planetary science missions.

    2012-09-01

    Resistance to antibiotics has increased recently to a dramatic extend, and the pipeline of new antibiotics is almost dry for the 5 next years. Failures happen already for trivial community acquired infections, like pyelonephritis, or peritonitis, and this is likely to increase. Difficult surgical procedures, transplants, and other immunosuppressive therapies will become far more risky. Resistance is mainly due to an excessive usage of antibiotics, in all sectors, including the animal one. Action is urgently needed. Therefore, an alliance against MDRO has been recently created, which includes health care professionals, consumers, health managers, and politicians. The document highlights the different proposed measures, and represents a strong consensus between the different professionals, including general practitioners, and veterinarians.

  16. Exogenous nitric oxide and bubble formation in divers.

    Prevention of bubble formation is a central goal in standard decompression procedures. Previously we have shown that exercise 20-24 h prior to a dive reduces bubble formation and increases survival in rats exposed to a simulated dive. Furthermore, we have demonstrated that nitric oxide (NO) may be involved in this protection; blocking the production of NO increases bubble formation while giving rats a long-lasting NO donor 20 h and immediately prior to a dive reduces bubble formation. This study determined whether a short-lasting NO donor, nitroglycerine, reduced bubble formation after standard dives and decompression in man. A total of 16 experienced divers were randomly assigned into two groups. One group performed two dives to 30 m of seawater (msw) for 30 min breathing air, and performed exercise at an intensity corresponding to 30% of maximal oxygen uptake during the bottom time. The second group performed two simulated dives to 18 msw for 80 min breathing air in a hyperbaric chamber, and remained sedentary during the bottom period. The first dive for each diver served as the control dive, whereas the divers received 0.4 mg of nitroglycerine by oral spray 30 min before the second dive. Following the dive, gas bubbles in the pulmonary artery were recorded using ultrasound. The open-water dive resulted in significantly more gas bubbles than the dry dive (0.87 +/- 1.3 vs 0.12 +/- 0.23 bubbles per square centimeter). Nitroglycerine reduced bubble formation significantly in both dives from 0.87 +/- 1.3 to 0.32 +/- 0.7 in the in-water dive and from 0.12 +/- 0.23 to 0.03 +/- 0.03 bubbles per square centimeter in the chamber dive. The present study demonstrates that intake of a short-lasting NO donor reduces bubble formation following decompression after different dives.

  17. Fostering change within organizational participants of multisectoral health care alliances.

    A touted advantage of multisectoral health care alliances is their ability to coordinate diverse constituencies and pursue community health goals in ways that allow them to make greater progress than each constituency could independently. However, participating organizations may have goals that do not entirely overlap or necessarily align with the alliance's goals, which can weaken or undermine an alliance's efforts. Fostering changes within participating organizations in ways that are consistent with the alliance's goals (i.e., alliance-oriented change) may be one mechanism by which alliances can coordinate diverse activities and improve care in their local communities. We examined whether alliance-oriented change within participating organizations is associated with alliance decision-making and conflict management style, level of participation, perceptions of alliance participation benefits and costs, and awareness of alliance activities within participating organizations. The study used two rounds of survey data collected from organizational participants of 14 alliances participating in the Robert Wood Johnson Foundation's Aligning Forces for Quality program. Alliance participants generally reported low levels of alliance-oriented change within their organizations as a result of the alliance and its activities. However, participants reporting higher levels of internal change in response to alliance activities had more positive perceptions of alliance decision-making style, higher levels of participation in alliance activities, more positive perceptions of alliance participation benefits relative to costs, and greater awareness of alliance activities across multiple levels of their respective organizations. Despite relatively low levels of alliance-oriented change within participating organizations, alliances may still have the means to align the goal orientations of a diverse membership and foster change that may extend the reach of the alliance in the community.

    Working on NASA missions allows engineers and scientists to hone their skills. Creating devices for the high-stress rigors of space travel pushes designers to their limits, and the results often far exceed the original concepts. The technologies developed for the extreme environment of space are often applicable here on Earth. Some of these NASA technologies, for example, have been applied to the breathing apparatuses worn by firefighters, the fire-resistant suits worn by racecar crews, and, most recently, the deep-sea gear worn by U.S. Navy divers.

    OBJECTIVE: To investigate the role of a patient foramen ovale in the pathogenesis of multiple brain lesions acquired by sport divers in the absence of reported decompression symptoms. DESIGN: Prospective double blind cohort study. SETTING: Diving clubs around Heidelberg and departments of neuroradiology and neurology. SUBJECTS: 87 sport divers with a minimum of 160 scuba dives (dives with self contained underwater breathing apparatus). MAIN OUTCOME MEASURES: Presence of multiple brain lesions visualised by cranial magnetic resonance imaging and presence and size of patent foramen ovale as documented by echocontrast transcranial Doppler ultrasonography. RESULTS: 25 subjects were found to have a right-to-left shunt, 13 with a patent foramen ovale of high haemodynamic relevance. A total of 41 brain lesions were detected in 11 divers. There were seven brain lesions in seven divers without a right-to-left shunt and 34 lesions in four divers with a right-to-left shunt. Multiple brain lesions occurred exclusively in three divers with a large patent foramen ovale (P = 0.004). CONCLUSIONS: Multiple brain lesions in sport divers were associated with presence of a large patent foramen ovale. This association suggests paradoxical gas embolism as the pathological mechanism. A patent foramen ovale of high haemodynamic relevance seems to be an important risk factor for developing multiple brain lesions in sport divers. PMID:9116544

    The risky working environments of divers and pilots, and the possible role of extreme ambient pressure in carotid stenosis, make ischemic stroke an important occupational concern among these professionals. In this study, we aimed to evaluate the association of being exposed to hyperbaric or hypobaric conditions with carotid artery stenosis by comparing common carotid intima-media thickness (CCIMT) and blood flow velocities of cerebral arteries in divers and pilots using carotid duplex ultrasound (CDUS) and transcranial Doppler (TCD). CDUS and transtemporal TCD were performed in 29 divers, 36 pilots and 30 control participants. Medical history, blood pressure, lipid profile and blood sugar were recorded to control the previously well-known risk factors of atherosclerosis. Findings of the CDUS and TCD [including: CCIMT and blood flow velocities of internal carotid artery (ICA), common carotid artery (CCA), and middle cerebral artery (MCA)] of divers and pilots were compared with those of the control group using regression analysis models. Both right and left side CCIMT were significantly higher in divers (P < 0.05) and pilots (P < 0.05) in comparison with the control group. Carotid index [peak systolic velocity (PSV) of ICA/PSV of CCA) of divers and pilots were also higher than the control group. TCD findings were not significantly different between divers, pilots, and the control group. Increased CCIMT and carotid index in diver and pilot groups appear to be suggestive of accelerated atherosclerosis of carotid artery in these occupational groups.

    1991-01-01

    As many industries face uncertain and changing environments, strategic alliances are rapidly emerging as a vehicle for interorganizational cooperation. Similarly in health care, alliances represent a mechanism for organizations to seek collaborative solutions to common problems. Drawing on a general typology, alliances in health care are categorized as service, opportunistic, or stakeholder alliances. Existing health care alliances serve to illustrate and characterize the purpose, structure, and operation of each of the three types. Strategic alliances offer significant challenges in managing the inherently fragile relationships within these emerging organizational forms. These challenges center around issues of commitment (v. control) as the underlying managerial philosophy; expectations for alliance performance; managing relationships, communication, and operations; member participation in alliance programs and activities; and stability of alliances over time. Alliances require new ways of thinking about organizations. Sensitivity to their unique characteristics and understanding the factors that can lead to their success are essential to managing them effectively.

    Relationship education programs have been shown as an effective way to increase relationship functioning. There is less known about how process factors, such as alliance with the leader or group dynamics, affect outcomes in these interventions. We examined group cohesion and alliance with the leader in a relationship education program tailored for individuals. Specifically, we examined whether participants' ratings (n = 126) of the group cohesion and alliance with the leader were associated with changes in relationship adjustment, relationship confidence, and communication quality from pre- to postintervention. The results demonstrated that participants' perceptions of the cohesion among the members in their relationship education group, but not the leader-participant alliance, made a significant contribution to the changes in participants' relationship functioning. These results suggest that the group dynamics among the members in the group are important ingredients in relationship education. Implications for relationship programs are provided. © FPI, Inc.

  16. Simple rules for making alliances work.

    PubMed

    Hughes, Jonathan; Weiss, Jeff

    2007-11-01

    Corporate alliances are growing in number--by about 25% a year--and account for up to a third of revenues and value at many companies. Yet some 60% to 70% of them fail. What is going wrong? Because alliances involve interdependence between companies that may be competitors and may also have vastly different operating styles and cultures, they demand more care and handling than other business arrangements, say Hughes and Weiss, management consultants at Vantage Partners. The authors have developed five principles--based on their two decades of work with alliances -to complement the conventional advice on alliance management: (1) Focus less on defining the business plan and more on how you and your partner will work together. (2) Develop metrics pegged not only to alliance goals but also to performance in working toward them. (3) Instead of trying to eliminate differences, leverage them to create value. (4) Go beyond formal systems and structures to enable and encourage collaborative behavior. (5) Be as diligent in managing your internal stakeholders as you are in managing the relationship with your partner. Companies that have adopted these principles have radically improved their alliance success rate. Schering-Plough, for example, engages in a systematic "alliance relationship launch": four to six weeks of meetings at which the partners explore potential challenges, examine key differences and develop shared protocols for managing them, and establish mechanisms for day-to-day decision making. Blue Cross and Blue Shield of Florida measures the quality of alliance progress through regular surveys of both its own staff and its partners'. These companies have learned that the conventional advice is not so much wrong as incomplete. The five simple rules can help fill in the blanks.

    The aim of the study was to retrospectively analyze diving fatalities occurring in Primorje-Gorski Kotar County (northern Croatian littoral), Croatia between 1980 and 2010 in order to identify differences between fatally injured tourist and resident divers, as well as temporal changes in the frequency of diver deaths. Medico-legal and police reports of 47 consecutive fatal diving cases were reviewed to determine the frequency of death among divers in relation to year and month of death, age, sex, nationality, organization of diving, diving type, and health condition. The majority of victims were foreign citizens (59.6%) most of whom fell victim to scuba diving (70.4%). It was found that 79% of resident divers succumbed during free-diving. The number of diving fatalities increased significantly in the last three decades, especially among free-divers. Of the victims, 93% were males, usually belonging to younger age groups with tourist divers being significantly older than local divers. And 31.9% of divers, mostly tourists, showed signs of acute, chronic, or congenital pathological conditions. Fatally injured foreign divers differ from resident diver fatalities in diving method and age. Tourists are the group most at risk while scuba diving according to the Croatian sample. Occupational scuba divers and free-divers are the group most at risk among resident divers. This study is an important tool in uncovering the most common victims of diving and the related risk factors. It also highlights the problems present in the legal and medical monitoring of recreational divers and discusses possible pre-event, event, and post-event preventive actions that could lead to reduced mortality rates in divers. © 2013 International Society of Travel Medicine.

    Efforts to form this Alliance began in 2008 to showcase the impact testing capabilities within the southern United States. Impact testing customers can utilize SITA partner capabilities to provide supporting data during all program phases-materials/component/ flight hardware design, development, and qualification. This approach would allow programs to reduce risk by providing low cost testing during early development to flush out possible problems before moving on to larger scale1 higher cost testing. Various SITA partners would participate in impact testing depending on program phase-materials characterization, component/subsystem characterization, full-scale system testing for qualification. SITA partners would collaborate with the customer to develop an integrated test approach during early program phases. Modeling and analysis validation can start with small-scale testing to ensure a level of confidence for the next step large or full-scale conclusive test shots. Impact Testing Facility (ITF) was established and began its research in spacecraft debris shielding in the early 1960's and played a malor role in the International Space Station debris shield development. As a result of return to flight testing after the loss of STS-107 (Columbia) MSFC ITF realized the need to expand their capabilities beyond meteoroid and space debris impact testing. MSFC partnered with the Department of Defense and academic institutions as collaborative efforts to gain and share knowledge that would benefit the Space Agency as well as the DoD. MSFC ITF current capabilities include: Hypervelocity impact testing, ballistic impact testing, and environmental impact testing.

  20. Recreational Diver Behavior and Contacts with Benthic Organisms in the Abrolhos National Marine Park, Brazil.

    2016-03-01

    In the last two decades, coral reefs have become popular among recreational divers, especially inside marine protected areas. However, the impact caused by divers on benthic organisms may be contributing to the degradation of coral reefs. We analyzed the behavior of 142 scuba divers in the Abrolhos National Marine Park, Brazil. We tested the effect of diver profile, reef type, use of additional equipment, timing, and group size on diver behavior and their contacts with benthic organisms. Eighty-eight percent of divers contacted benthic organism at least once, with an average of eight touches and one damage per dive. No significant differences in contacts were verified among gender, group size, or experience level. Artificial reef received a higher rate of contact than pinnacle and fringe reefs. Specialist photographers and sidemount users had the highest rates, while non-users of additional equipment and mini camera users had the lowest contact rates. The majority of contacts were incidental and the highest rates occurred in the beginning of a dive. Our findings highlight the need of management actions, such as the provision of pre-dive briefing including ecological aspects of corals and beginning dives over sand bottoms or places with low coral abundance. Gathering data on diver behavior provides managers with information that can be used for tourism management.

    Although otitis externa (OE) is a common disease, data related to (military) divers are limited. This study aimed to determine the incidence of OE in military divers during their initial training. We also wished to consider seasonal influences on incidence and whether early detection increases completion of the diving course. From January 2011 to October 2016 the Royal Netherlands Navy Diving School trained 189 divers. Up to December 2015 we used the training records for the analyses. From January 2016 onward all divers were prospectively screened. Pearson's chi-squared 2 and Fisher's exact tests were used to analyse the data. In the 162 included divers, 30 cases of OE were identified. The incidence in 2016 was significantly higher than in 2011-2015 (17/35 (49%) versus 13/127 (10%), P < 0.001). Almost all cases developed after three weeks of diving. No influence of season was found (P = 0.354). Early diagnosis and treatment of OE does not seem to affect completion of diving courses (P = 0.28). Only in three cases did a diver have to discontinue the course due to OE. This study suggests that OE is more frequent among military divers than earlier reported, most likely caused by prolonged water exposure. Diving activities can often be continued with standard topical treatment.

    Irish search and recovery divers dive on a voluntary basis to recover missing persons. During these procedures, they encounter situations not typically part of ordinary human experience and might be expected to experience psychological effects as a result. To investigate the association of post-traumatic stress disorder (PTSD) symptoms with previous experience of missing person recovery among divers, and to investigate the coping mechanisms used. Self-administered questionnaires were distributed to all 206 active search divers in Ireland. A validated questionnaire, the Impact of Event Scale revised (IES-R), was used together with a coping questionnaire to compare the level of symptoms in divers with and without recovery experience, and to describe the main coping factors. One hundred and fifty-five questionnaires were returned, a response rate of 75%. Divers with prior missing person recovery experience scored lower on all three PTSD dimensions (avoidance, intrusion and hyper-arousal) with a significant difference for intrusion (P < 0.001). Coping mechanisms listed by the divers were search and recovery training, support from peers and search unit and sense of duty. The results do not support the hypothesis of an accumulation of traumatic experience in experienced divers but may indicate a survivor bias of the most resilient individuals, or a wearing off of vulnerability to traumatic events with experience.

    A survey was conducted in the northern district of Yamaguchi, Japan to determine the relationship between neurological diving accidents and risk factors among commercial breath-hold divers (Ama). A questionnaire was distributed to 381 Ama divers who are members of the Ama diving union. We sought information on their dive practices (depth of single dive, single dive time, surface interval, length of dive shifts, lunch break) and the presence or absence of medical problems, such as hypertension, cardiac arrhythmia, diabetic mellitus and other issues. Of the 381 Ama divers, 173 responded (45%): 29 were Funado (assisted-descent using weights) and 144 Cachido (unassisted) divers. Twelve had experienced strokelike symptoms during or after repetitive breath-hold diving; 11 were assisted and one unassisted (Funado vs. Cachido). Only two of 12 divers with neurological diving accidents had musculoskeletal symptoms. Neurological events were significantly correlated with dive depth, dive time, and surface interval; however, they were not related to medical history. Neurological diving accidents are more likely to happen among assisted Ama divers than unassisted ones. Repetitive breath-hold diving with a deep dive depth, long dive time, and short surface interval predisposes divers to decompression illness, which characteristically manifests as cerebral stroke.

    In the last two decades, coral reefs have become popular among recreational divers, especially inside marine protected areas. However, the impact caused by divers on benthic organisms may be contributing to the degradation of coral reefs. We analyzed the behavior of 142 scuba divers in the Abrolhos National Marine Park, Brazil. We tested the effect of diver profile, reef type, use of additional equipment, timing, and group size on diver behavior and their contacts with benthic organisms. Eighty-eight percent of divers contacted benthic organism at least once, with an average of eight touches and one damage per dive. No significant differences in contacts were verified among gender, group size, or experience level. Artificial reef received a higher rate of contact than pinnacle and fringe reefs. Specialist photographers and sidemount users had the highest rates, while non-users of additional equipment and mini camera users had the lowest contact rates. The majority of contacts were incidental and the highest rates occurred in the beginning of a dive. Our findings highlight the need of management actions, such as the provision of pre-dive briefing including ecological aspects of corals and beginning dives over sand bottoms or places with low coral abundance. Gathering data on diver behavior provides managers with information that can be used for tourism management.

    The value of the commonly required routine annual medical examination of occupational divers has been questioned, and there is a need for a robust, evidence-based system of health surveillance for this group of workers. To determine whether the medical examination and investigation component of occupational divers' routine comprehensive health surveillance adds significantly to the information gained from the questionnaire component in determining fitness for diving. An occupational diver database was interrogated to identify divers issued with a 'limited' medical clearance or considered 'unfit' for diving over a 5-year period. Reasons for the 'unfit' or 'limited' designation and the source of the critical information, whether the annual health questionnaire or the medical examination or questionnaire component (or both) of the initial or 5-yearly comprehensive medical evaluation, was recorded. For divers completing the 5-yearly repeat comprehensive medical evaluation, the sensitivity and specificity of the questionnaire alone for determining unfitness for diving was compared with that of a nominal 'gold standard'. Of 5178 certificates issued to 2187 divers over a 5-year period, 158 (3%) were provisionally designated as either 'limited' or 'unfit'. Of nine divers identified by the examination component of the 5-yearly comprehensive medical evaluation, four were eventually designated 'fit', two 'limited', and three were lost to follow up. None who had completed subsequent investigations remained 'unfit'. The sensitivity and specificity of the questionnaire to detect unfit divers compared with the gold standard were 84.6 and 99.3%, respectively, and its accuracy was 98.9%. The current New Zealand occupational diver medical certification process, comprising annual health questionnaires and 5-yearly full examinations, detects all health issues critical to the determination of fitness to dive. © 2016 Royal Australasian College of Physicians.

  6. Oral changes in divers working with electrical welding/cutting underwater.

    Divers performing electrical welding/cutting underwater often complain about a metallic taste in the mouth, strictly related to their work. In a nationwide clinical investigation, professional commercial divers were examined orally. The majority of the divers complained about a metallic taste. An increased surface deterioration of dental amalgam was detected in those divers who had performed electrical welding/cutting during the previous two years. In addition, after clinical and bacteriological examination, divers were found to belong to a caries risk group. In order to study the intraoral electrical activity, several actual dives were performed. When they were welding or cutting, the electrical activity registered intraorally in dental amalgam test samples was too low in magnitude to explain the metallic taste and the clinical appearance of the amalgam. The divers were dressed in a dry-suit and full-face mask. When leakage occurred or when a hot-water heated suit was used higher electrical activity was registered. This activity was still not of a magnitude, which could explain the symptoms theoretically, although a metallic taste and a subjective change in the divers dental amalgam were provoked. No increased levels of Hg and Cu could be detected in saliva, blood or urine. The flux density of the intraoral magnetic field created by a current of 650 ADC was calculated and measured to be 1.15 mT, which is approximately 25 times stronger than that of the earth. When exposing divers in-vivo to a field generated by a 200 ADC current, no symptoms other than magnetophosphenes were reported, such as metallic taste. The divers helmets offered almost no shielding effect towards the magnetic field. In-vitro exposure of dental amalgams to a magnetic field (1.15 mT; 50 Hz) increased the mobility of cupper and especially mercurity in the superficial layers of the amalgam after 24 h exposure, and gave rise to slight morphological changes within the amalgam.

  11. Alliances and reproductive success in Camargue stallions.

    1999-03-01

    A study of a herd of Camargue horses Equus caballus, showed that while the majority of high-ranking stallions held single-male harems, some sons of low-ranking mares, being low ranking themselves, formed alliances that could last a lifetime. The two stallions were each other's closest associate and preferential grooming partner. Alliances were based on coalitions in which either both partners confronted an intruder synchronously or the dominant of the pair tended the female(s) while the subordinate simultaneously displayed towards the rival. Alliance partners were of similar age but were not more closely related to each other than to other stallions in the herd. Long-term paternity data revealed that subordinates sired close to a quarter of the foals born into the alliance group, and significantly more foals than low-ranking stallions in the herd adopting a 'sneak'-mating strategy. The dominant appeared to benefit from the presence of his subordinate partner. Fights occurred all year round, and the subordinate stallion of each alliance pair fought outside competitors more than twice as often as the dominant. Forming short-term alliances before defending mares on their own may enhance long-term reproductive success for both partners. Other benefits to both partners include higher survivorship of their foals and increased access to proven reproductive mares. These results suggest that the relationship between alliance partners is based on mutualism, but several conditions for reciprocity seem to be fulfilled: the benefit to the dominant (assistance in fights), and the benefit to the subordinate (access to reproduction), are both costly to the other partner and delayed in time.

    2013-01-01

    In certain parts of the United States and Canada, and northern Ontario in particular, the dimorphic fungus Blastomyces dermatitidis is endemic and can cause infection in exposed individuals. The site of infection is usually pulmonary, causing respiratory and constitutional symptoms, but can also affect other sites in the body. Symptom severity can vary substantially from no symptoms to fatal acute respiratory distress syndrome. The present report describes a 27-year-old professional diver who had recently worked in northern Ontario, who developed symptoms of pneumonia and exhibited atypical findings on chest imaging. He was diagnosed with blastomycosis based on histopathological findings and fungal culture, and was treated with amphotericin B and itraconazole in accordance with treatment guidelines. While outdoor occupations in endemic areas increase the risk of infection, there is no literature specifically identifying professional diving as an occupational risk for blastomycosis.

    Two separate species of Aeromonas, A. sobria (not listed as a species in Bergey's Manual of Determinative Bacteriology, 8th ed.) and A. hydrophila, were primary pathogens isolated from the leg wound of a diver conducting operations in polluted waters. This is the first recorded instance of a primary infection of soft tissue in a human caused by two species of Aeromonas, one of which was resistant to tetracycline. Because of the very rapid development of this wound infection, cytotoxicity of these organisms was examined in several biological systems. A. sobria was hemolytic for sheep erythrocytes, cytotoxic for Y-1 adrenal cells, and enterotoxic in rabbit ligated intestinal loops, whereas A. hydrophila was hemolytic and cytotoxic. Pertinent clinical, bacteriological, and environmental features of the case are presented. PMID:500794

    An online survey was offered to recreational divers in Tasmania to ascertain if they have an understanding of how pressure affects their health and if they considered an annual dive medical necessary. A total of 98 recreational divers completed the survey, five of these had never had a dive medical while 74 felt that if they passed their dive medical they do not have any potential illness. Sixty five saw the dive medical as a comprehensive health check. This project provided an insight to Tasmanian recreational divers' understanding of and attitude towards the value of a dive medical.

    Decompression Sickness (DCS) may occur when divers decompress from a hyperbaric environment. To prevent this, decompression procedures are used to get safely back to the surface. The models whose procedures are calculated from, are traditionally validated using clinical symptoms as an endpoint. However, DCS is an uncommon phenomenon and the wide variation in individual response to decompression stress is poorly understood. And generally, using clinical examination alone for validation is disadvantageous from a modeling perspective. Currently, the only objective and quantitative measure of decompression stress is Venous Gas Emboli (VGE), measured by either ultrasonic imaging or Doppler. VGE has been shown to be statistically correlated with DCS, and is now widely used in science to evaluate decompression stress from a dive. Until recently no mathematical model has existed to predict VGE from a dive, which motivated the development of the Copernicus model. The present article compiles a selection experimental dives and field data containing computer recorded depth profiles associated with ultrasound measurements of VGE. It describes a parameter estimation problem to fit the model with these data. A total of 185 square bounce dives from DCIEM, Canada, 188 recreational dives with a mix of single, repetitive and multi-day exposures from DAN USA and 84 experimentally designed decompression dives from Split Croatia were used, giving a total of 457 dives. Five selected parameters in the Copernicus bubble model were assigned for estimation and a non-linear optimization problem was formalized with a weighted least square cost function. A bias factor to the DCIEM chamber dives was also included. A Quasi-Newton algorithm (BFGS) from the TOMLAB numerical package solved the problem which was proved to be convex. With the parameter set presented in this article, Copernicus can be implemented in any programming language to estimate VGE from an air dive.

    This paper analyzes the effects of airline alliances on the allied partners output by comparing the traffic change observed between the pre- and the post-alliance period. First, a simple methodology based on traffic passenger modelling is developed, and then an empirical analysis is conducted using time series from four global strategic alliances (Wings, Star Alliance, oneworld and SkyTeam) and 124 alliance routes. The analysis concludes that, all other things being equal, strategic alliances do lead to a 9.4%, on average, improvement in passenger volume.

    2015-08-01

    Managers have been advocating the use of artificial reef wrecks to diversify the experiences of recreational divers and thereby reduce the well-known impact on reefs. To examine whether artificial reef wrecks can serve as substitutes for historic shipwrecks this paper discusses the attitude of Australian divers to wreck diving in general and to artificial reef wrecks in particular. While the overwhelming majority of divers surveyed accepted the need for control, the experienced divers were less interested in artificial reef wrecks and less prepared to tolerate controls over their perceived freedom to dive wrecks. We present projections that show that this legacy issue will have largely resolved itself by 2025 due to attrition and natural ageing.

    Therapists' awareness of ruptures in the alliance may determine whether such ruptures will prove beneficial or obstructive to the therapy process. This study investigated the associations between therapists' recognition of these ruptures, and changes in clients' alliance ratings and symptom reports, using time-series data in a naturalistic treatment setting. Eighty-four clients treated by 56 therapists completed alliance measures after each session, and the clients also completed symptom measures at the beginning of each session. Therapists' recognition of alliance rupture in non-rupture sessions was positively associated with clients' alliance ratings in the next session and this effect was significantly higher when rupture did occur. There was also a significant interaction effect for functioning ratings: Therapists' recognition of alliance ruptures abolished the negative effect of ruptures on clients' symptom ratings in the following session. These results highlight the importance of therapists' recognition of deterioration in the alliance for a repair process to take place that may eventually lead to an improved relationship and outcome.

  2. Does self-certification reflect the cardiac health of UK sport divers?

    Since 2009, the United Kingdom diving incident data show an increasing number of fatalities in the over-50s age group. Previous studies also suggest some divers take cardiac medications. Since 2001, diving medicals have not been mandatory for UK sport divers. Instead, an annual medical self-certification form, submitted to their club/school or training establishment, is required. We documented in a survey of UK sport divers the prevalence of cardiac events and medications and the frequency of medical certifications. An anonymous on-line questionnaire was publicised. Measures included diver and diving demographics, prescribed medications, diagnosed hypertension, cardiac issues, events and procedures, other health issues, year of last diving medical, diagnosed persistent foramen ovale (PFO), smoking and alcohol habits, exercise and body mass index. Of 672 completed surveys, hypertension was reported by 119 (18%) with 25 of these (21%) having not had a diving medical. Myocardial infarction 6 (1%), coronary artery bypass grafting 3 (< 1%), atrial fibrillation 19 (3%) and angina 12 (2%) were also reported. PFOs were reported by 28 (4%), with 20 of these opting for a closure procedure. From 83 treated incidences of decompression illness (DCI), 19 divers reported that a PFO was diagnosed. Divers inevitably develop health problems. Some continue to dive with cardiac issues, failing to seek specialised diving advice or fully understand the role of the diving medical. Physicians without appropriate training in diving medicine may inform a diver they are safe to continue diving with their condition without appreciating the potential risks. The current procedure for medical screening for fitness to dive may not be adequate for all divers.

    During competitive diving, divers jump up from 1 to 3 m springboards or 5 to 10 m platforms and dive into the water. The impact forces are very large in the water entry phase, and, as such, microtraumatic injuries are common due to the tremendous physical stress placed on the diver. Low-back pain (LBP) is the most frequently reported symptom in divers. This study aimed to extract possible risk factors related to LBP from physical and technical characteristics in Japanese elite junior divers. Eighty-three elite junior divers (42 men and 41 women) in Japan were included in this study. LBP was assessed by a questionnaire, interview and physical examination during a national training camp. Morphological data, physical fitness and diving skills were also evaluated. The factors related to LBP were extracted by using logistic-regression analysis and the forward-selection method (likelihood ratio). A total of 37.3% (31 reports) of back pain occurred in the lumbar region. Shoulder flexibility (OR 0.919; 95% CI 0.851 to 0.992) and age (OR 0.441; 95% CI 0.239 to 0.814) were recognised as factors related to LBP in male-elite junior divers, whereas only age (OR 0.536; 95% CI 0.335 to 0.856) was a factor in female-elite junior divers. Our results suggest that shoulder flexibility is important for preventing LBP in elite-male junior divers, since they require full shoulder flexion during the water entry phase. Limited shoulder flexibility could cause lumbar hyperextension when adjusting for the angle of water entry.

    The strategic alliance, vitally important as an isolated practice in the oil and gas business, also fits a broad pattern of innovation by which the industry is redefining itself for prosperity in a new energy age. The industry is experiencing a renaissance in almost every aspect, from technological breakthroughs to innovative business practices to new products and markets. An inevitable outgrowth of such rapid and fundamental change is an evolution in business relationships. The strategic alliance is at the forefront of this trend. Development of new relationships capitalizes on, and partly results from, enormous advances in technology and finance. The paper discusses new relationships, the outsourcing rage, integrating work flows, and technological advances.

    Construction well divers in Taiwan reportedly suffer a high prevalence of dysbaric osteonecrosis. We studied five divers working at the same construction site. We recorded their diving methods, diving depths, bottom times, work patterns, water temperatures, and heart rates. We also monitored gas bubbles in the subclavian vein in selected dives. A crude but effective hot-water system protected divers against hypothermia and allowed them to work in 24 degrees-27 degrees C water. Divers worked approximately 6.6 h a day and progressed approximately 3.0 m a day while excavating an average of 148 buckets of sand and rock each weighing 49.5 kg. The divers sustained a heart rate increase of 49%. Sixty percent of their equivalent single dive bottom times exceeded the U.S. Navy's no-decompression limits. Two cases of venous bubbles were detected, and one of these divers showed symptoms of decompression sickness. The prolonged bottom time and lack of a decompression schedule probably contributed to a risk of decompression sickness and dysbaric osteonecrosis.

Beginning in 2006 NSF funding will enable ESSEA will expand to 40 institutions of higher learning that are committed to teacher education in Earth system science. The program will support participating institutions with funding, training, and standards-aligned courses and resources for pre- and in-service teachers. As a result, teachers will be prepared to teach Earth system science using inquiry-based classroom methods, geoscience data and tools. From 1999-2005, the NASA funded ESSEA Program delivered online Earth system science professional development for K-12 teachers through a network of 20 colleges and universities. The program was led by the Institute for Global Environmental Strategies (IGES) and based on a trio of 16-week online courses (for elementary, middle, and high school teachers) that had been developed and piloted by NASA's Classroom of the Future at Wheeling Jesuit University. The ESSEA program's mission was to: 1) support universities, colleges, and science education organizations delivering the K-12 online graduate courses; 2) strengthen teachers' understanding of Earth system science; 3) demonstrate the ability to deliver exceptional professional development to a national audience; and 4) create a solid infrastructure to sustain the program. As of spring 2006, the courses had been used by 40 faculty at 20 institutions educating over 1,700 k-12 teachers in Earth system science. Although NASA funding ended in late 2005, the courses continue to be offered by 17 of the original 20 institutions. Through NSF funding beginning in late 2006, IGES will enhance and build upon the ESSEA foundation by: 1.Using the ESSEA courses as a model to introduce newly upgraded Earth

The program was led by the Institute for Global Environmental Strategies (IGES) and based on a trio of 16-week online courses (for elementary, middle, and high school teachers) that had been developed and piloted by NASA's Classroom of the Future at Wheeling Jesuit University. The ESSEA program's mission was to: 1) support universities, colleges, and science education organizations delivering the K-12 online graduate courses; 2) strengthen teachers' understanding of Earth system science; 3) demonstrate the ability to deliver exceptional professional development to a national audience; and 4) create a solid infrastructure to sustain the program. As of spring 2006, the courses had been used by 40 faculty at 20 institutions educating over 1,700 K-12 teachers in Earth system science. Through NSF funding beginning in late 2006, IGES is enhancing and building on the ESSEA foundation by: 1. Introducing extensive use of data, models and existing Earth system educational materials to support the courses; 2. Implementing a rigorous evaluation program designed to demonstrate growth in teachers' Earth

  19. Toward a conceptual alliance about therapeutic alliance: a voyage through the Inferno.

    PubMed

    Szajnberg, N M

    1996-01-01

    I suggest that there is not a conceptual consensus in psychoanalysis regarding the therapeutic alliance. Some argue that the unobjectionable part of the transference should be facilitated; some argue that there is no unobjectionable part of the transference, that all parts should be subjected to analysis. There are those who argue that the therapeutic alliance exists in early treatment; others who argue that it exists later. I suggest using a classical text, Dante's Inferno, as a paradigm for a journey of self-discovery. By reviewing the moments of hesitation that Dante experiences with Virgil and how these are overcome, we cast light on our current problem on the nature of the therapeutic alliance and how to facilitate it. The components of the unobjectionable are related to Winnicott's idea of the maturational processes and Hartmann's (1958) ideas of the primary and secondary autonomous function. Based on their considerations, we make recommendations for use of the therapeutic alliance.

    The aim of this study is to analyze the robustness of the three major airline alliances' (i.e., Star Alliance, oneworld and SkyTeam) route networks. Firstly, the normalization of a multi-scale measure of vulnerability is proposed in order to perform the analysis in networks with different sizes, i.e., number of nodes. An alternative node selection criterion is also proposed in order to study robustness and vulnerability of such complex networks, based on network efficiency. And lastly, a new procedure - the inverted adaptive strategy - is presented to sort the nodes in order to anticipate network breakdown. Finally, the robustness of the three alliance networks are analyzed with (1) a normalized multi-scale measure of vulnerability, (2) an adaptive strategy based on four different criteria and (3) an inverted adaptive strategy based on the efficiency criterion. The results show that Star Alliance has the most resilient route network, followed by SkyTeam and then oneworld. It was also shown that the inverted adaptive strategy based on the efficiency criterion - inverted efficiency - shows a great success in quickly breaking networks similar to that found with betweenness criterion but with even better results.

  10. A wireless bio-sensing microfluidic chip based on resonating 'μ-divers'.

    PubMed

    Xue, Cong; Yang, Chen; Xu, Tiegang; Zhan, Jing; Li, Xinxin

    2015-05-21

    A magneto-elastic resonant 'micro-diver' system (MER-μDS) is proposed and developed for rapid liquid-phase detection of pathogens in a wireless way. The magneto-elastic micro-resonator (i.e., the μ-diver) is placed in the micro-chamber of the MER-μDS that is connected to the inlet/outlet for flow of the liquid analyte and a closed-loop micro-channel. After specific attachment of the analyte onto the μ-diver, the μ-diver is conveyed by the flow into the detection segment of the channel, around which a metal micro-coil is wound for both excitation resonance of the μ-diver and reading of its resonance frequency signal. After the pre-functionalized μ-diver captures the analyte and, then, is driven into the detection channel segment, the added mass induced resonant frequency shift can be wirelessly sensed by the coil. The micro-system features rapid and repeatable liquid-phase bio-sensing and the wireless signal readout scheme is favorable to real-time pathogen detection in liquid food, e.g., milk or juice, for food safety applications. An equivalent circuit model is established for design of the magneto-elastic μ-diver. After a bar-shaped μ-diver with length-extensional bulk-resonance mode is optimally designed and micro-fabricated, the MER-μDS is formed by micro-machining/assembling techniques. By placing a biotin-immobilized μ-diver into the wireless micro-sensing system, avidin-attached magnetic beads are detected to calibrate the mass sensitivity as 0.061 Hz pg(-1), which well confirms the modeling result. By using the antibody-immobilized μ-diver, PBS solution with an E. coli concentration of 10(2)-10(8) CFU mL(-1) is detected, resulting in a corresponding wireless f0-shift sensing signal of about 300-2300 Hz and a limit of detection of 10(2) CFU mL(-1). Food safety application potential of the MER-μDS technique is proven by detection of E. coli added to orange and apple juices (E. coli concentration: 10(4)-10(8) CFU mL(-1)).

  12. Decompression sickness in breath-hold divers: a review.

    PubMed

    Lemaitre, Frederic; Fahlman, Andreas; Gardette, Bernard; Kohshi, Kiyotaka

    2009-12-01

    Although it has been generally assumed that the risk of decompression sickness is virtually zero during a single breath-hold dive in humans, repeated dives may result in a cumulative increase in the tissue and blood nitrogen tension. Many species of marine mammals perform extensive foraging bouts with deep and long dives interspersed by a short surface interval, and some human divers regularly perform repeated dives to 30-40 m or a single dive to more than 200 m, all of which may result in nitrogen concentrations that elicit symptoms of decompression sickness. Neurological problems have been reported in humans after single or repeated dives and recent necropsy reports in stranded marine mammals were suggestive of decompression sickness-like symptoms. Modelling attempts have suggested that marine mammals may live permanently with elevated nitrogen concentrations and may be at risk when altering their dive behaviour. In humans, non-pathogenic bubbles have been recorded and symptoms of decompression sickness have been reported after repeated dives to modest depths. The mechanisms implicated in these accidents indicate that repeated breath-hold dives with short surface intervals are factors that predispose to decompression sickness. During deep diving, the effect of pulmonary shunts and/or lung collapse may play a major role in reducing the incidence of decompression sickness in humans and marine mammals.

  13. Partial dereverberation used to characterize open circuit scuba diver signatures.

    2014-08-01

    The use of passive acoustics to detect self-contained underwater breathing apparatus (SCUBA) divers is useful for nearshore and port security applications. While the performance of a detector can be optimized by understanding the signal's spectral characteristics, anechoic recording environments are generally not available or are cost prohibitive. A practical solution is to obtain the source spectra by equalizing the recording with the inverse of the channel's impulse response. This paper presents a dereverberation method for signal characterization that is subsequently applied to four recorded SCUBA configurations. The inverse impulse response is computed in the least-square sense, and partial dereverberation of SCUBA is performed over the 6-18 kHz band. Results indicate that early reflections and late reverberation added as much as 6.8 dB of energy. Mean unadjusted sound pressure levels computed over the 0.3-80 kHz band were 130 ± 5.9 dB re 1 μPa at 1 m. Bubble noise carries a significant amount of the total energy and masks the regulator signatures from 1.3 to 6 kHz, depending on the regulator configuration. While the dereverberation method is applied here to SCUBA signals, it is generally applicable to other sources if the impulse response of the recording environment can be obtained separately.

    2016-12-01

    The Interdisciplinary Earth Data Alliance (IEDA) is leading an EarthCube (EC) Integrative Activity to develop a governance structure and technology framework that enables partner data systems to share technology, infrastructure, and practice for documenting, curating, and accessing heterogeneous geoscience data. The IEDA data facility provides capabilities in an extensible framework that enables domain-specific requirements for each partner system in the Alliance to be integrated into standardized cross-domain workflows. The shared technology infrastructure includes a data submission hub, a domain-agnostic file-based repository, an integrated Alliance catalog and a Data Browser for data discovery across all partner holdings, as well as services for registering identifiers for datasets (DOI) and samples (IGSN). The submission hub will be a platform that facilitates acquisition of cross-domain resource documentation and channels users into domain and resource-specific workflows tailored for each partner community. We are exploring an event-based message bus architecture with a standardized plug-in interface for adding capabilities. This architecture builds on the EC CINERGI metadata pipeline as well as the message-based architecture of the SEAD project. Plug-in components for file introspection to match entities to a data type registry (extending EC Digital Crust and Research Data Alliance work), extract standardized keywords (using CINERGI components), location, cruise, personnel and other metadata linkage information (building on GeoLink and existing IEDA partner components). The submission hub will feed submissions to appropriate partner repositories and service endpoints targeted by domain and resource type for distribution. The Alliance governance will adopt patterns (vocabularies, operations, resource types) for self-describing data services using standard HTTP protocol for simplified data access (building on EC GeoWS and other `RESTful' approaches).

    2015-01-01

    Objective This study examined the temporal relation between therapeutic alliance and outcome in two treatments for bulimia nervosa (BN). Method Eighty adults with BN symptoms were randomized to 21 sessions of integrative cognitive-affective therapy (ICAT) or enhanced cognitive-behavioral therapy (CBT-E). Bulimic symptoms (i.e., frequency of binge eating and purging) were assessed at each session and post-treatment. Therapeutic alliance (Working Alliance Inventory) was assessed at sessions 2, 8, 14, and post-treatment. Repeated-measures analyses using linear mixed models with random intercepts were conducted to determine differences in alliance growth by treatment and patient characteristics. Mixed-effects models examined the relation between alliance and symptom improvement. Results Overall, patients in both treatments reported strong therapeutic alliances. Regardless of treatment, greater therapeutic alliance between (but not within) subjects predicted greater reductions in bulimic behavior; reductions in bulimic behavior also predicted improved alliance. Patients with higher depression, anxiety, or emotion dysregulation had a stronger therapeutic alliance in CBT-E than ICAT, while those with more intimacy problems had greater improvement in therapeutic alliance in ICAT compared to CBT-E. Conclusions Therapeutic alliance has a unique impact on outcome, independent of the impact of symptom improvement on alliance. Within- and between-subject effects revealed that changes in alliance over time did not predict symptom improvement, but rather that individuals who had a stronger alliance overall had better bulimic symptom outcomes. These findings indicate that therapeutic alliance is an important predictor of outcome in the treatment of BN. PMID:25894667

    The use of natural resources and the services they provide often do not have an explicit price and are therefore undervalued in decision-making, leading to environmental degradation. To 'monetize' the benefits from these services requires the use of non-market valuation techniques. Using a stated preference survey of recreational divers in Barbados conducted between 2007 and 2009, the economic value of marine biodiversity to recreational SCUBA divers in Barbados was estimated. In addition to a variety of demographic variables, divers were asked about their level of experience, expenditures related to travel and diving, and encounters with fish and sea turtles. Divers then completed a choice experiment, selecting between alternative dives with varying characteristics including price, crowding, fish diversity, encounters with sea turtles, and coral cover. Results indicate that divers in Barbados have a clear appreciation of reef quality variables. Willingness to pay for good coral cover, fish diversity and presence of sea turtles is significantly higher than prices paid for dives. In general, divers valued reef attributes similarly, although their appreciation of low density of divers at a site and high coral cover varied with prior diving experience. The results of this study demonstrate the economic value generated in Barbados by the recreational SCUBA diving industry and highlight the potential for substantial additional economic contributions with improvements to the quality of a variety of reef attributes. These results could inform management decisions regarding reef use and sea turtle conservation, and could aid in the development of informed 'win-win' policies aimed at maximizing returns from diving while reducing negative impacts often associated with tourism activities.

    2012-09-01

    To identify barriers to stakeholder alignment and strategies used by 14 multi-stakeholder alliances participating in the Aligning Forces for Quality initiative to overcome these barriers. The study used a mixed method, comparative case study design. Alliances were categorized as more or less highly aligned based on an alignment index constructed from survey responses. Six alliances (top and bottom quartile) were selected for more in-depth qualitative analysis. Semi-structured interviews of key informants were used to identify factors that distinguished more highly aligned alliances from less highly aligned alliances. Market context was one of the most important factors differentiating alliances. More highly aligned alliances had more extensive histories of collaboration, established more credibility in the local community, and were more effective at balancing collaborative initiatives against competitive interests. More highly aligned alliances also took more active approaches to build consensus among stakeholders regarding alliance initiatives, and were able to successfully utilize small decision-making bodies to foster this consensus. In contrast, leadership credibility, leadership stability, and trust were important facilitators of alignment for all alliances, regardless of the level of alignment. These factors intersect and overlap in a multitude of ways to influence stakeholder alignment. Alignment in an alliance context is critical for leveraging the unique knowledge, skills, and abilities of stakeholders in ways that can build capacity to improve the health of the community in ways that cannot be achieved independently by stakeholders. The findings highlight the need for multifaceted approaches to promote stakeholder alignment.

  1. The Empirical Analysis of Impact of Alliances on Airline Operations

    NASA Technical Reports Server (NTRS)

    Iatrou, Kostas; Alamdari, Fariba

    2003-01-01

    Airline alliances are dominating the current air transport industry with the largest carriers of the world belonging to one of the four alliance groupings - "Wings", Star Alliance, one world, SkyTeam - which represent 56% of world Revenue Passenger Kilometers. Although much research has been carried out to evaluate the impact of alliance membership on performance of airlines, it would be of interest to ascertain the degree of impact perceived by participating airlines in alliances. It is the purpose of this paper to gather the opinion of all the airlines, belonging to the four global alliance groupings on the impact alliances have had on their traffic and on their performance in general To achieve this, a comprehensive survey of the alliance management departments of airlines participating in the four global strategic alliances was carried out. With this framework the survey has examined which type of cooperation among carriers (FFP, Code Share, Strategic Alliance without antitrust immunity, Strategic Alliance with antitrust immunity) has produced the most positive impact on traffic and which type of route (short haul, long haul, hub-hub, hub-non hub, non hub-non hub) has been mostly affected. In addition, the respondent airlines quantified the effect alliances have had on specific areas of their operation, such as load factors, traffic, costs, revenue and fares. Their responses have been analysed under each global alliances grouping, under airline and under geographic region to establish which group, type of carrier and geographic region has benefited most. The results show that each of the four global alliances groupings has experienced different results according to the type of collaboration agreed amongst their member airlines.

    Objective To determine the prevalence of dental symptoms in recreational scuba divers and describe the distribution of these symptoms on the basis of diver demographics, diving qualifications and dive conditions during the episode of dental pain.Design A survey was designed and distributed through online social media platforms dedicated to scuba diving. A convenience sample of 100 recreational divers was obtained by this method.Main outcome measures The outcome measures of interest were: diver demographics, diving characteristics (level of certification, number of dives completed), occurrence of dental problems during a dive, and details of the episode.Results Forty-one percent of the respondents experienced dental symptoms during a dive. Barodontalgia was the most frequently experienced dental symptom during a dive.Conclusion Within the limits of the small sample size and online method of recruitment, the findings of this study suggest that a high proportion of recreational divers may experience dental symptoms during a dive. It would be meaningful to ensure that dental decay and damaged restorations are addressed before a dive and that the mouthpiece design be evaluated in case of complaints of temporomandibular discomfort during a dive.

  3. An observation of venous gas emboli in divers and susceptibility to decompression sickness.

    PubMed

    2015-03-01

    Decompression sickness (DCS) results from the formation of bubbles within the tissues and blood in response to a reduction in environmental pressure. Venous gas emboli (VGE) are common after diving and are usually only present in small numbers. Greater VGE numbers are an indication of decompression stress, and can be reliably detected using ultrasound imaging. To examine the relationship between production of VGE following a routine dive and the risk of DCS. A matched population of divers with and without a history of DCS were monitored for the production of VGE at 15-minute intervals using ultrasound, following a 405 kPa air dive in a hyperbaric chamber using the DCIEM air decompression table. VGE production was graded using a validated grading system and the data analysed to compare maximum VGE grade and duration of VGE formation. Eleven divers with a history of DCS were compared with 13 divers with no history of DCS. Divers with a history of DCS demonstrated both a higher maximum grade (P=0.04) and longer duration (P=0.002) of VGE production compared to divers without a history of DCS. Higher maximum VGE grades and longer durations of VGE following decompression were associated with a history of DCS and, in particular, musculoskeletal DCS. Although the exact mechanism of DCS remains poorly understood, our data suggest some individuals are inherently more prone to develop VGE, increasing the probability of DCS. Modification of diving practices in those with high VGE grades could potentially decrease DCS risk in these individuals.

  4. Serum albumin as a biomarker of capillary leak in scuba divers with neurological decompression sickness.

    2014-10-01

    Prior reports have shown that decompression sickness (DCS) in scuba divers is accompanied by vascular endothelium damage attributed to gas emboli formation, resulting in capillary leak with hemoconcentration. The significance of serum albumin as a biomarker of vascular permeability in this condition has been insufficiently investigated. We studied whether there was a relationship between low serum albumin values on admission and the occurrence of neurological DCS. Demographic, diving, and laboratory data of 52 randomly selected DCS divers were compared with those of 52 asymptomatic divers referred for inadequate decompression. The diagnostic performance of serum albumin in predicting neurological DCS was assessed. Both groups did not differ from the variables examined. Serum albumin was significantly lower in injured divers than in controls (38.7 ± 3 g · L(-1) vs. 41 ± 2.9 g · L(-1)). At a cut-off value of 35.2 g · L(-1), we found a specificity of 98% (95% CI 90-100) and a sensitivity of 16% (95% CI 7-28) for the prediction of neurological DCS development. Our findings suggest that hypoalbuminemia at initial presentation, albeit rare, accurately predicts the occurrence of neurological DCS in scuba divers. The prognostic value of this biomarker and the potential beneficial role of albumin infusion in more severe cases remain to be investigated.

    Recent increases in both the frequency and severity of coral bleaching events have spurred numerous surveys to quantify the immediate impacts and monitor the subsequent community response. Most of these efforts utilize conventional diver-based methods, which are inherently time-consuming, expensive, and limited in spatial scope unless they deploy large teams of scientifically-trained divers. In this study, we evaluated the effectiveness of the Along-Track Reef Imaging System (ATRIS), an automated image-acquisition technology, for assessing a moderate bleaching event that occurred in the summer of 2011 in the Florida Keys. More than 100,000 images were collected over 2.7 km of transects spanning four patch reefs in a 3-h period. In contrast, divers completed 18, 10-m long transects at nine patch reefs over a 5-day period. Corals were assigned to one of four categories: not bleached, pale, partially bleached, and bleached. The prevalence of bleaching estimated by ATRIS was comparable to the results obtained by divers, but only for corals > 41 cm in size. The coral size-threshold computed for ATRIS in this study was constrained by prevailing environmental conditions (turbidity and sea state) and, consequently, needs to be determined on a study-by-study basis. Both ATRIS and diver-based methods have innate strengths and weaknesses that must be weighed with respect to project goals.

    The physical characteristics and simple lung ventilatory indices (FVC, FEV 1, FEV 1/FVC) of 404 commercial divers employed by companies operating in the North Sea were analysed. These findings were correlated with the diving experience and maximum operating depth of each diver. All the divers were men of average height 176-9 cm, and weight 77-1 kg which is greater than average for active Western males, but only 6% were more than 120% of their predicted weight. The average duration of commercial diving was 7-1 years, 11% of divers having less than one year's experience. Sixty-seven per cent had worked at a maximum depth of 200 ft (61 m) and only 6% had worked deeper than 500 ft (153 m). The mean forced vital capacity (FVC) was 120-4% of the predicted value which indicated that they could voluntarily move large amounts of gas in and out of their lungs. This was greatest in the divers who when deepest. The mean forced expired volume in one second (FEV 1) was 117% of the predicted value showing that expiratory airflow capacity was also increased, but to a lesser extent than the FVC.

    We investigated whether professional air diving with no decompression illness causes any long-term changes in cognitive functions. The all-male participants consisted of 18 healthy control (HC) volunteers and 32 divers. Divers were divided into two subgroups as moderate exposure group, Divers-I (DI) and extensive exposure group, Divers-II (DII). Participants were administered a comprehensive neuropsychological battery and event-related potentials (ERPs) were recorded while they performed auditory oddball task and visual continuous performance test (CPT). P3 waves in oddball and CPT were significantly attenuated and peak latencies were prolonged in both diver groups compared with HC. Amplitude decrements in CPT P3 were graded with respect to level of diving exposure. Neuropsychologically, DII group displayed significantly poorer performance than HC and DI groups in measures of visuo-constructional and visual long-term memory tests. DI group performed better than HC group in some measures of planning ability. Most of the changes in neurophysiological measures and poorer neuropsychological performance were found in DII group, and this might be interpreted as a red flag for the reflection of the slowly progressing deleterious effects of silent bubbles in brain function. This study reports impairments in certain neuropsychological measures and apparent neurophysiological markers pointing to slow cognitive decline referring to long-term effects of diving.

    The protected coral reefs off the coast of Malaysia receive numerous tourists, while also being as fishing grounds. These joint environmental pressures raise the need for additional costly conservation measures. It is natural to consider the potential for expanding the 'user pays' principle, already implemented in the form of various user fees. This study explores the potential for price discrimination among scuba divers at Sipadan in Malaysia. The study applies a choice experiment to estimate scuba divers willingness to pay higher user fees for avoiding decreases of or getting improvements in environmental and recreational aspects of the diving experience. We investigate how sensitivity to fee size and hence willingness to pay vary with suitable selected characteristics of divers. We find potentials for a third degree price discrimination strategy exploiting higher willingness to pay among foreign divers (45%), male divers (16%) and people who has visited Sipadan several times (25%). Thus, revised pricing structures could significantly increase funds for the preservation of Sipadan. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This study assessed the relation between altered cardiac function and the development of interstitial pulmonary edema in scuba divers. Fifteen healthy men performed a 30-minute scuba dive in open sea. They were instructed to fin for 30 minutes and were wearing wet suits. Before and immediately after immersion, cardiac indexes and extravascular lung water were measured using echocardiography and lung ultrasound, respectively. The mean ultrasound lung comet score increased from 0 to 4.6 ± 3.4. The diameter of the inferior caval vein increased by 47 ± 5.2%, systolic pulmonary artery pressure by 105 ± 8.6%, left atrial volume by 18.0 ± 3.3%, and left ventricle end-diastolic volume by 10 ± 2.4% suggesting that both right and left ventricular (LV) filling pressures were elevated. Doppler studies showed an increased mitral E peak (+2.5 ± 0.3%) and E/A ratio (+22.5 ± 3.4%) with a decreased mitral A peak (-16.4 ± 2.7%), E peak deceleration time (-14.5 ± 2.4%) consistent with rapid early LV filling but without a change in LV stroke volume. There was an increase in right/left ventricle diameter ratio (+33.6 ± 4.8%) suggesting a relative increase in right-sided heart output compared with the left. Furthermore, the lung comet score correlated significantly with inferior caval vein diameter, systolic pulmonary artery pressure, right/left ventricle diameter ratio, and E-wave deceleration time. In conclusion, the altered right/left heart stroke volume balance could play an essential role in the development of immersion pulmonary edema. Our findings have important implications for the pathogenesis of cardiogenic pulmonary edema.

    Building a therapeutic alliance with a patient with pathological narcissism or narcissistic personality disorder is a challenging process. A combined alliance building and diagnostic strategy is outlined that promotes patients' motivation and active engagement in identifying their own problems. The main focus is on identifying grandiosity, self-regulatory patterns, and behavioral fluctuations in their social and interpersonal contexts while engaging the patient in meaningful clarifications and collaborative inquiry. A definition of grandiosity as a diagnostic characterological trait is suggested, one that captures self-criticism, inferiority, and fragility in addition to superiority, assertiveness, perfectionism, high ideals, and self-enhancing and self-serving interpersonal behavior. These reformulations serve to expand the spectrum of grandiosity-promoting strivings and activities, capture their fluctuations, and help clinicians attend to narcissistic individuals' internal experiences and motivation as well as to their external presentation and interpersonal self-enhancing, self-serving, controlling, and aggressive behavior. A case example illustrates this process.

    The purpose of this article is to describe a renewed partnership between a collegiate school of nursing and a community hospital. Universities and hospitals are searching for creative solutions to increase the number of registered nurses available to meet the demand for nursing care. An affiliation agreement had been in existence for many years, but health care system imperatives made it necessary to redesign the partnership between nursing education and nursing service. The model used to develop this new partnership is based on the work done in the field of management and is in the form of a strategic alliance. The success of a strategic alliance depends on two key factors: the relationship between partners and partnership performance. Identified outcomes show that this partnership is helping to meet the increasing demand for nursing care by building student capacity, satisfying mutual needs of faculty and clinical staff, and removing economic barriers. This article describes the development of the strategic alliance, its current status, and strategies for the future.

    This study investigates the utility and psychometric properties of a new measure of psychotherapy process, the Alliance Negotiation Scale (ANS; Doran, Safran, Waizmann, Bolger, & Muran, 2012). The ANS was designed to operationalize the theoretical construct of negotiation (Safran & Muran, 2000), and to extend our current understanding of the working alliance concept (Bordin, 1979). The ANS was also intended to improve upon existing measures such as the Working Alliance Inventory (WAI; Horvath & Greenberg, 1986, 1989) and its short form (WAI-S; Tracey & Kokotovic, 1989) by expanding the emphasis on negative therapy process. The present study investigates the psychometric validity of the ANS test scores and interpretation-including confirming its original factor structure and evaluating its internal consistency and construct validity. Construct validity was examined through the ANS' convergence and divergence with several existing scales that measure theoretically related constructs. The results bolster and extend previous findings about the psychometric integrity of the ANS, and begin to illuminate the relationship between negotiation and other important variables in psychotherapy research.

    2013-07-01

    Post-decompression shock with plasma volume deficit is a very rare event that has been observed under extreme conditions of hypobaric and hyperbaric exposure in aviators and professional divers. We report a case of severe hypovolemic shock due to extravasation of plasma in a recreational scuba diver presenting with inner ear decompression sickness. Impaired endothelial function can lead to capillary leak with hemoconcentration and hypotension in severe cases. This report suggests that decompression-induced circulating bubbles may have triggered the endothelial damage, activating the classic inflammatory pathway of increased vascular permeability. This observation highlights the need for an accurate diagnosis of this potentially life-threatening condition at the initial presentation in the Emergency Department after a diving-related injury. An elevated hematocrit in a diver should raise the suspicion for the potential development of capillary leak syndrome requiring specific treatment using albumin infusion as primary fluid replacement.

    2007-01-01

    Although U.S. Navy diving is remarkably safe, because of the high-risk environment in which military divers work, accidents and mishaps do occur. Failures in leadership and situation awareness (particularly in risk and time assessment) were found to be the two most common causes of fatal and nonfatal U.S. Navy diving accidents and near misses. Responses to an attitude survey showed that junior divers want to ask questions, but senior divers do not desire to be questioned. In other high reliability industries (e.g. aviation, medicine) methods have been developed to identify, analyze and mitigate human error. The relevance of these techniques for U.S. Navy diving are discussed.

  20. Odds Ratio Meta-Analysis and Increased Prevalence of White Matter Injury in Healthy Divers.

    PubMed

    Connolly, Desmond M; Lee, Vivienne M

    2015-11-01

    Increased white matter hyperintensities (WMH) on magnetic resonance imaging (MRI) brain scans of high altitude aircrew and altitude chamber workers indicate that exposure to low ambient pressure (hypobaria) promotes white matter injury. If associated with frequent decompression stress then experienced divers should also exhibit more WMH, yet published case-control studies are inconsistent. This meta-analysis evaluated the prevalence of WMH in healthy divers and controls. Eligible studies compared experienced divers (or hyperbaric workers) without neurological decompression illness with nondiving controls, identified from multiple database searches and reference list reviews. Studies were scored for sample size, recruitment bias, control matching, MRI sensitivity, and confounding factors before grading as low, medium, or high quality. Meta-analysis of odds ratios (OR) with 95% confidence intervals (CI) was conducted on all data using a random effects model and repeated after exclusion of low-quality studies. There were 11 eligible studies identified. After data adjustment to exclude diving accidents, these encompassed 410 divers and 339 controls, of which 136 (33%) and 79 (23%), respectively, exhibited WMH (OR 1.925, 95% CI 1.088 to 3.405). Excluding four low-quality studies eliminated meta-analysis heterogeneity, with 98 of 279 divers (35%) and 44 of 232 controls (19%) exhibiting WMH (OR 2.654, 95% CI 1.718 to 4.102). Results suggest that repeated hyperbaric exposure increases the prevalence of white matter injury in experienced healthy divers without neurological decompression illness. This is consistent with reports of increased WMH in asymptomatic altitude workers and an association with intensity of dysbaric exposure.

    OBJECTIVE--To examine the possibility that subclinical damage may persist after clinical recovery from neurological decompression illness. METHODS--The neuraxes of 71 divers with medical histories of neurological decompression illness and 37 non-diver controls were examined by recording the somatosensory evoked potentials produced on stimulation of the posterior tibial and median nerves. RESULTS--Although the tests gave some objective support for the presence of "soft" residual neurological symptoms and signs, no evidence was given for the presence of subclinical damage. CONCLUSIONS--The contention that neurological damage persists after full clinical recovery from the neurological decompression illness was not supported. PMID:7849848

    Voluntary breath-holding (BH) elicits several hemodynamic changes, but little is known about maximal static immersed-body BH. We hypothesized that the diving reflex would be strengthened with body immersion and would spare more oxygen than maximal dry static BH, resulting in a longer BH duration. Eleven trained breath-hold divers (BHDs) performed a maximal dry-body BH and a maximal immersed-body BH. Cardiac output (CO), stroke volume (SV), heart rate (HR), left ventricular end-diastolic volume (LVEDV), contractility index (CTI), and ventricular ejection time (VET) were continuously recorded by bio-impedancemetry (PhysioFlow PF-05). Arterial oxygen saturation (SaO2) was assessed with a finger probe oximeter. In both conditions, BHDs presented a bi-phasic kinetic for CO and a tri-phasic kinetic for SV and HR. In the first phase of immersed-body BH and dry-body BH, results (mean ± SD) expressed as percentage changes from starting values showed decreased CO (55.9 ± 10.4 vs. 39.3 ± 16.8 %, respectively; p < 0.01 between conditions), due to drops in both SV (24.9 ± 16.2 vs. 9.0 ± 8.5 %, respectively; p < 0.05 between conditions) and HR (39.7 ± 16.7 vs. 33.6 ± 17.0 %, respectively; p < 0.01 between conditions). The second phase was marked by an overall stabilization of hemodynamic variables. In the third one, CO kept stabilizing due to increased SV (17.0 ± 20.2 vs. 10.9 ± 13.8 %, respectively; p < 0.05 between conditions) associated with a second HR drop (14.0 ± 10.0 vs. 12.7 ± 8.9 %, respectively; p < 0.01 between conditions). This study highlights similar time-course patterns for cardiodynamic variables during dry-body and immersed-body BH, although the phenomenon was more pronounced in the latter condition.

    Alliance ruptures, impasses, and transference-countertransference enactments are inevitable in therapy. A growing body of evidence suggests that repairing ruptures in the alliance is related to positive outcome (Safran, Muran, & Eubanks-Carter, 2011). Our research program has led to the development of training methods to enhance therapists' abilities to detect and work constructively with alliance ruptures and negative therapeutic process (Safran et al., 2014). This article outlines relevant theoretical underpinnings, intervention principles, and empirical findings.

    2016-09-01

    Some people with well-managed insulin-dependent diabetes can dive safely. Those cleared to participate should control tightly the variables that impact blood glucose levels, including activity, timing, food and insulin. Honest self-assessment is critical. A diabetic diver should cancel a dive if seasick, unusually anxious, or following significant high or low blood glucose levels in the preceding 24 hours. The diver should enter the water with a blood glucose level above 8.3 mmol·L⁻¹ and below 14 mmol·L⁻¹ with a stable or rising trend in blood glucose established with glucose tests at 90, 60, and 30 minutes prior to a dive. The diver should carry emergency glucose at all times and brief dive buddies about hypoglycaemia procedures. This is a personal account of the author's experience diving with type 1 diabetes and details how the UHMS/DAN recommendations are put into practice on dive days. Key elements of the self-assessment process, long- and rapid-acting insulin adjustments, meal timing, responses to blood glucose trends, handling hypoglycaemia and approaching multi-dive days are described. Some considerations for people using insulin pumps are also briefly discussed.

    The association between alliance level and outcome in psychotherapy has been extensively studied. One way to expand this knowledge is to study alliance patterns. The main aims of this study were to examine how frequent alliance patterns with ruptures or rupture-repair episodes were in a naturalistic sample of psychotherapies in primary care, and if three alliance patterns (a Rupture pattern, a Repair pattern, and a No Rupture pattern) were differentially associated with treatment outcome. The psychotherapies (N = 605) included a wide range of different treatment orientations and patient diagnoses. Alliance patterns were studied at session-to-session level, using patient-rated alliance scores. Outcome data were analyzed using longitudinal multilevel modeling with a slopes-as-outcomes model. The Repair pattern accounted for 14.7% (n = 89) of the treatments, 10.7% (n = 65) exhibited a Rupture pattern, and 74.5% (n = 451) contained no ruptures. The Rupture pattern was associated with inferior treatment outcomes. The Repair pattern was, in longer treatments, associated with better outcomes than the No Rupture pattern. The results support theory about the importance of ruptures in the therapeutic alliance and suggest that identification of alliance ruptures is important in alliance-outcome research, for feedback purposes in clinical practice, and in training of therapists.

    To create consistency among the health promotion alliances in which it engages, the National Heart Foundation of Australia (NHFA) undertook to develop guidelines for the formation, management and sustainability of alliances for cardiovascular health. A condensed review of the key themes in the literature and survey of staff who were involved in health promotion alliances were conducted to guide the development of a checklist and template Memorandum of Understanding (MOU) for use by staff when engaging in health promotion alliances. The essential factors for forming, managing and sustaining alliances are explored extensively throughout the literature. Here we provide a condensed overview of the key themes relating to the advantages and barriers of health promotion alliances, plus a useful set of principles for forming, managing and, where applicable, sustaining health promotion alliances. Alliances are a crucial part of the cardiovascular health work of the NHFA and, indeed, broader approaches to promote health. These alliances may involve simply sharing knowledge and creating networks, or they may involve complex arrangements to address broad health issues.

    Humanism and multiculturalism are partners in an evolutionary alliance. Humanistic and multicultural psychotherapies have historically influenced each other. Humanism represents the third force in psychotherapy, while multiculturalism embodies the fourth developmental stage. Multiculturalism embraces humanistic values grounded in collective and social justice contexts. Examples of multicultural humanistic constructs include contextualism, holism, and liberation. Certainly, the multicultural-humanistic connection is a necessary shift in the evolution of psychotherapy. Humanism and multiculturalism participate in the development of an inclusive and evolutionary psychotherapy. (c) 2012 APA, all rights reserved.

    Divers have for some years been complaining about a metallic taste in the mouth while electrically welding and cutting underwater. This paper reports on results from an assessment of this problem. It was hypothesized that the magnetic fields arising from the welding or cutting current could correlate with the reported symptoms. The intraoral magnetic flux density was calculated to 1.15 mT, at 650 ADC, in a normal cutting situation. This was verified in vivo. This magnetic field was shown to contain an AC component that is a candidate for inducing secondary currents in the oral tissues and restorative materials. Five submerged divers exposed to a magnetic field of 0.35 mT did not report any metallic taste. Magnetophosphenes were reported by 1 diver. (Magnetophosphenes are luminous impressions due to excitement of the retina by a magnetic field in addition to or in place of impingement of light rays.) Only a slight shielding effect to magnetic fields was observed due to a copper-brass helmet. An in vitro model for exposure of dental amalgams to magnetic fields was designed. Recommendations for decreasing the magnetic field surrounding the diver in practical work is given.

    Fitzpatrick, Daniel T.; Conkin, Johnny

    2003-01-01

    INTRODUCTION: There is limited data about the long-term pulmonary effects of nitrox use in divers at shallow depths. This study examined changes in pulmonary function in a cohort of working divers breathing a 46% oxygen enriched mixture while diving at depths less than 12 m. METHODS: A total of 43 working divers from the Neutral Buoyancy Laboratory (NBL), NASA-Johnson Space Center completed a questionnaire providing information on diving history prior to NBL employment, diving history outside the NBL since employment, and smoking history. Cumulative dive hours were obtained from the NBL dive-time database. Medical records were reviewed to obtain the diver's height, weight, and pulmonary function measurements from initial pre-dive, first year and third year annual medical examinations. RESULTS: The initial forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) were greater than predicted, 104% and 102%, respectively. After 3 yr of diving at the NBL, both the FVC and FEV1 showed a significant (p < 0.01) increase of 6.3% and 5.5%, respectively. There were no significant changes in peak expiratory flow (PEF), forced mid-expiratory flow rate (FEF(25-75%)), and forced expiratory flow rates at 25%, 50%, and 75% of FVC expired (FEF25%, FEF50%, FEF75%). Cumulative NBL dive hours was the only contributing variable found to be significantly associated with both FVC and FEV1 at 1 and 3 yr. CONCLUSIONS: NBL divers initially belong to a select group with larger than predicted lung volumes. Regular diving with nitrox at shallow depths over a 3-yr period did not impair pulmonary function. Improvements in FVC and FEV1 were primarily due to a training effect.

    This study aimed at demonstrating that the neoprene wetsuit provides not only thermal protection. Compression it exerts on the diver's shell significantly impacts hydromineral homeostasis by restraining the systemic vascular capacity and secondarily increasing urine output on dry land and during scuba diving. 8 healthy divers underwent five 2-h sessions: sitting out of water in trunks (control situation), sitting out of water wearing a wetsuit, and 3 wetsuit scuba-immersed sessions at 1, 6 and 12 msw depth, respectively. Urine volumes and blood samples were collected. Hemoglobin (Hb), hematocrit (Ht) and plasma sodium concentration were measured. Interface pressure between the garment and the skin was measured at 17 sites of the body shell, with a pressure transducer. Mean interface pressures between wetsuit and skin amounted to: 25.8±2.8 mm Hg. Whatever the depth, elastic recoil tension of wetsuit material was unchanged by immersion. Weight loss was respectively 2 and 3 times greater when wetsuit was worn out of water (430 g) and during immersion (710 g) than when divers did not wear any wetsuit out of water (235 g; p<0.05). Urine volume accounted for 85% of weight loss in either session. Weight loss and urine volume were similar whatever immersion depth. The decrease in plasma volume amounted to 8% of urine volume when divers did not wear any wetsuit out of water, and to 30% when wetsuit was worn out of water or during immersion. Diving wetsuit develops a pressure effect that alters diver's hydromineral homeostasis. During immersion, the wetsuit pressure merges into the larger main effect of hydrostatic pressure to reduce water content of body fluids, unrelated to immersion depth.

    2012-03-01

    We investigated risk factors associated with ascending rapidly and/or losing buoyancy control among recreational divers. Dive and diver information were collected and depth/time loggers attached to recreational divers. Case dives recording an ascent > 18 m per min were compared with control dives made at the same dive site and time by divers recording ascents ≤ 18 m per min. In a second analysis, case dives with reported buoyancy problems were compared with control dives during which no problems were reported. Conditional logistic regression identified factors significantly associated with ascending faster than 18 m per min or reporting a buoyancy problem. In total, 1,032 dive profiles were collected. Case dives (n = 71) recording an ascent > 18 m per min were compared with 282 control dives. The main risk factor for making a rapid ascent was a loss of buoyancy control. Case dives were also shorter. Dives resulting in reported buoyancy problems (n = 68 cases) were compared with 320 control dives. The three main risk factors for buoyancy problems were an inability to describe how to check for neutral buoyancy, reportedly not being in control during the final ascent and maximum ascent rates that were a mean of 20% faster than during control dives. Further research is necessary to identify if ascending rapidly is the result of a loss of buoyancy control, a lack of ascent rate reference or a failure to appreciate the potential consequences of ascending rapidly. The inability of many divers to describe how to check for neutral buoyancy also deserves attention.

    Cellular responses to inputs that vary both temporally and spatially are determined by complex relationships between the components of cell signaling networks. Analysis of these relationships requires access to a wide range of experimental reagents and techniques, including the ability to express the protein components of the model cells in a variety of contexts. As part of the Alliance for Cellular Signaling, we developed a robust method for cloning large numbers of signaling ORFs into Gateway® entry vectors, and we created a wide range of compatible expression platforms for proteomics applications. To date, we have generated over 3000 plasmids that are available to the scientific community via the American Type Culture Collection. We have established a website at www.signaling-gateway.org/data/plasmid/ that allows users to browse, search, and blast Alliance for Cellular Signaling plasmids. The collection primarily contains murine signaling ORFs with an emphasis on kinases and G protein signaling genes. Here we describe the cloning, databasing, and application of this proteomics resource for large scale subcellular localization screens in mammalian cell lines. PMID:17192258

    The therapeutic alliance has historically emerged as a pantheoretical correlate of favorable psychotherapy outcomes. However, uncertainty remains about the direction of the alliance-outcome link, and whether it is affected by other contextual variables. The present study explored (a) if early alliance quality predicted subsequent symptom change while controlling for the effect of prior symptom change in interpersonal psychotherapy (IPT) for depression, and (b) whether baseline patient characteristics moderated the alliance-outcome relation (to help specify conditions under which alliance predicts change). Data derived from an open trial of 16 sessions of individual IPT delivered naturalistically to adult outpatients (N = 119) meeting criteria for major depression. Patients rated their sociodemographic, clinical, and interpersonal characteristics at baseline, their alliance with their therapist at Session 3, and their depressive symptoms at baseline, after every session, and at posttreatment. Data were analyzed using hierarchical linear modeling. Results indicated that alliance quality did not predict subsequent depression change, controlling for prior depression change. However, a significant education by alliance interaction emerged in predicting quadratic depression change (γ = .0007, p = .03); patients with higher levels of education who reported good early alliances with their therapists had the most positively accelerated change trajectory (i.e., faster depression reduction), whereas patients with higher levels of education who reported poorer early alliances had the most negatively accelerated change trajectory (i.e., slower depression reduction). The findings may help clarify a specific condition under which alliance quality influences subsequent improvement in an evidence-based treatment for depression. (PsycINFO Database Record

    This study aimed to examine perceptions of the working alliance in a sample of Spanish patients and therapists. The alliance was measured after the third and tenth psychotherapy sessions using patient and therapist versions of the Spanish adaptation of the Working Alliance Inventory (WAI). After both sessions, correlations between the patients' and therapists' ratings, both of total alliance and of the various dimensions of the alliance, were moderate at best. Moreover, after the third psychotherapy session, patients' scores for the total alliance and the Goal and Task subscales were significantly higher than the scores from their therapists in these dimensions. Following the tenth session, patient ratings exceeded those of their therapists only on the Task subscale. Finally, in contrast to the ratings of patients, therapists' alliance ratings increased significantly between the third and tenth sessions of psychotherapy. Certain recommendations are presented to improve the study of patient and therapist perceptions of the working alliance and to increase the convergence between them with regard to this central treatment variable.

    Smaller, multiple-stage fracture treatments, worked out by an alliance between a producing and a service company, were a significant element in reducing costs for fracturing Carthage Cotton Valley infill wells in Panola County, Texas. Pennzoil's infill drilling program takes advantage of the Texas Railroad Commission's (RRC) ruling that allows optional 80-acre well spacing in this tight gas-sand reservoir. Pennzoil spudded 29 wells between September 1992 and December 1993 and expects to spud 20 more in 1994. The Pennzoil-Halliburton alliance began in September 1992 for the purpose of drilling and completing Cotton Valley infill wells through 1993. The two companies share the cost of new technology development, with Pennzoil providing the rig times to test Halliburton technology. To date, the alliance has experimented with an elastic strain relaxation, a six-arm extensometer, and a water-recovery surfactant. Some of the features of the alliance are: Halliburton guarantees the availability of crews and equipment to meet Pennzoil's drilling and completion schedule; Halliburton technical advisor studies existing wells to find candidates for workover or refracture; the technical advisor analyzes, plants, and evaluates the ongoing program; and the alliance is not rigidly structured, and other service companies perform part of the work. Both parties have benefited financially from the alliance and well performance has met or exceeded expectations. The alliance has enabled Pennzoil to stay on a rigid and aggressive drilling schedule and through efforts of the alliance, fracture orientation has been confirmed.

    Worldwide, more than 1000 scuba (self-contained underwater breathing apparatus) diving injuries per year requiring hyperbaric recompression are documented. Approximately 80 to 90 fatalities per year are reported in North America. On average, there were 16 diving injuries requiring hyperbaric recompression therapy in scuba divers aged 19 years and younger in North America between 1988 and 2002. The youngest injured diver was 11 years old, and the youngest fatality was 14 years old during this time period. In the year 2000, certifying recreational scuba diving organizations lowered the minimum age to 8 from age 12 years for participation in the sport. We report a case of a highly trained adolescent scuba diver who, despite having advanced diving certifications, had 2 separate episodes of diving-related injuries requiring hyperbaric recompression therapy. A discussion of medical considerations in the care of the child and adolescent scuba diver is included.

    2012-01-01

    Therapeutic alliance has been frequently studied in individual counseling sessions; however, research on therapeutic alliance in residential settings for youth with mental health diagnoses has been limited. This may be due, in part, to the presence of multiple service providers often in caregiving roles. The purpose of this study was to examine the psychometric quality of a widely utilized measure of therapeutic alliance used in psychotherapy with youth in residential care where the treatment is provided by a trained married couple. We also compared the relationship between youth ratings of their male and female service provider, as well as examined correlations in ratings between youth and staff on therapeutic alliance. Finally, we investigated the direction, magnitude, and trajectory of change in therapeutic alliance over a 12-month period following admission into residential care. The method was a longitudinal assessment of 135 youth and 124 staff regarding therapeutic alliance over the course of 12 months or discharge from services. Results indicated strong psychometric properties and high correlations for youth ratings of both their male and female service providers. However, the correlation was low between youth and service provider ratings of alliance. Longitudinal analyses indicated that rates of therapeutic alliance changed over time. PMID:23264715

    The continuing underrepresentation of Native Americans in the geosciences can only mean that native voices go unheard in setting research agendas and priorities. This is particularly significant where issues such as global climate change impact the land and livelihood of Native American communities. This talk will outline progress towards a Geoscience Alliance, with participation by faculty from tribal colleges, universities, and research centers; native elders and community members; students (K12, undergraduate, and graduate); formal and informal educators; and other interested individuals. Our focus will be on defining goals for this alliance, i.e., new research in Geoscience education, defining best practices, inclusion of Native voices in Geoscience research, the potential for new collaborations, and promotion of opportunities for Native students and communities.

  7. The international Planetary Data Alliance: overview

    NASA Astrophysics Data System (ADS)

    Sarkissian, Alain; Crichton, Daniel J.; Gopala Krishna, B.

    The IPDA's main emphasis is to ease discovery, access and use of planetary data by world-wide scientists regardless of which agency is collecting and distributing the data. Ensuring proper capture, accessibility and availability of the data is the task of the individual space agencies. The IPDA is focusing on developing an international standard which allows the following capabilities: query, access and usage of data across international planetary data archive systems. While, trends in other areas of space science are concentrating on the sharing of science data from diverse standards and collection methods, the IPDA shall concentrate on promoting standards which drive common methods for collecting and describing planetary science data across the international community. Such an approach will better support the long term goal of easing data sharing across system and agency boundaries. An initial starting point for developing such a standard will be internationalization of NASA's Planetary Data System standards. We will present here the current activities of the Alliance.

The relationship between alliance and outcome has traditionally been studied based on measures that assess these therapy factors at a global level. However, the specific variations of the alliance process and their association with therapy segments that are relevant for change have not yet been fully examined. The present study examines the variations in the therapeutic alliance in 73 significant in-session events: 35 change and 38 stuck episodes identified through the observation of 14 short-term therapies of different theoretical orientations. Variations in the alliance were assessed using the VTAS-SF [Shelef, K., & Diamond, G. (2008). Short form of the revised Vanderbilt Therapeutic Alliance Scale: Development, reliability, and validity. Psychotherapy Research, 18, 433-443]. Nested analyses (HLM) indicate a statistically significant better quality of the alliance during change episodes.

  10. The relationship between diver experience levels and perceptions of attractiveness of artificial reefs - examination of a potential management tool.

    2013-01-01

    Artificial reefs are increasingly used worldwide as a method for managing recreational diving since they have the potential to satisfy both conservation goals and economic interests. In order to help maximize their utility, further information is needed to drive the design of stimulating resources for scuba divers. We used a questionnaire survey to explore divers' perceptions of artificial reefs in Barbados. In addition, we examined reef resource substitution behaviour among scuba divers. Divers expressed a clear preference for large shipwrecks or sunken vessels that provided a themed diving experience. Motives for diving on artificial reefs were varied, but were dominated by the chance of viewing concentrated marine life, increased photographic opportunities, and the guarantee of a 'good dive'. Satisfaction with artificial reef diving was high amongst novices and declined with increasing experience. Experienced divers had an overwhelming preference for natural reefs. As a management strategy, our results emphasize the capacity of well designed artificial reefs to contribute towards the management of coral reef diving sites and highlight a number of important areas for future research. Suggested work should validate the present findings in different marine tourism settings and ascertain support of artificial reefs in relationship to level of diver specialization.

    Retrospective case-control study. The intent of this study was to investigate the relationships between vertebral degenerative changes resulting in spinal canal stenosis, spinal cord lesions and the development of spinal cord decompression sickness (DCS) in scuba divers. Referral hyperbaric facility, Toulon, France. We examined 33 injured divers less than 50 years old by cervical and thoracic MRI and compared them with 34 matched control divers. The number of intervertebral disk abnormalities and the degree of canal compression were analyzed on T2-weighted sagittal images using a validated grading system developed recently. The presence and the distribution of hyperintense cord lesions in relation with the accident and the recovery status at 6 months were also assessed. Canal spinal narrowing was more common in injured divers than in controls (79% vs. 50%, OR=3.7 [95% CI, 1.3-10.8], P=0.021). We found a significant linear association between the extent of canal stenosis, multisegmental findings and the development of spinal cord decompression sickness. MRI intramedullary lesions were significantly more frequent in divers with incomplete recovery (OR=16 [95% CI, 2.6-99], P=0.0014), but statistical analysis failed to demonstrate a significant relationship between canal compression, signal cord abnormalities and a negative clinical outcome. These results suggest that divers with cervical and thoracic spinal canal stenosis, mainly due to disk degeneration, are at increased risk for the occurrence of spinal cord decompression sickness.

    KENNEDY SPACE CENTER, FLA. -- Andy Fish, an SRB retrieval diver and diver medical technician with United Space Alliance, is in the spotlight for helping rescue a diver in distress off Cape Canaveral Sept. 11. Fish and others were on a certification exercise on board Freedom Star, one of the Shuttle Rocket Booster retrieval ships, manned by USA workers. The ship was near the location of a lobster diving boat that radioed the U.S. Coast Guard for help when one of the divers experienced difficulty breathing on his return to the surface. Hearing the call for help, the captain of the Freedom Star offered to help. Fish had experience with distressed divers. He stayed with the diver in the recompression chamber aboard the Freedom Star until the ship reached Port Canaveral where a KSC Occupational Health doctor waited. The diver was stabilized and taken to Florida Hospital. .

    The authors offer a way of estimation of safety modes of decompression, based on definition of intensity of venous gas embolism (VGE) at each decompression and account of probability of illness of divers in series of tests. Intensity of VGE was determined with the help of ultrasonic gas bubbles Doppler radar. Comparative safety of standard modes of decompression of divers of the Navy was estimated, and also the modes, designed in accordance with mathematical model of decompression, offered by I. A. Voĭtsekhovich (1990), were done. The results testify, that use of ultrasonic radar for estimation of intensity of VGE at decompression and account of average and maximum probability of decompression illness in series of tests of modes permit to receive the comparative characteristic of safety of modes at small number of decompressions.

    The knowledge transfer efficiency (KTE) is closely relative to the success or failure of technology innovation in strategic alliances. This paper takes the KTE as the essential variable to establish the benefit function model of technology innovations to explore the KTE's influences on partners' innovative decisions under two different modes: independent innovations and alliance innovations. It is found that the higher the KTE, the greater the reducing extent of production costs is. The results could provide some theoretical supports for selections of the optimal competitive-ooperative relationship and managerial flexibility in technical innovation alliances.

    Diver visibility analyses and predictions, and water transparency in general, are of significant military and commercial interest. This is especially true in our current state, where ports and harbors are vulnerable to terrorist attacks from a variety of platforms both on and below the water (swimmers, divers, AUVs, ships, submarines, etc.). Aircraft hyperspectral imagery has been previously used successfully to classify coastal bottom types and map bathymetry and it is time to transition this observational tool to harbor and port security. Hyperspectral imagery is ideally suited for monitoring small-scale features and processes in these optically complex waters, because of its enhanced spectral (1-3 nm) and spatial (1-3 meters) resolutions. Under an existing NOAA project (CICORE), a field experiment was carried out (November 2004) in coordination with airborne hyperspectral ocean color overflights to develop methods and models for relating hyperspectral remote sensing reflectances to water transparency and diver visibility in San Pedro and San Diego Bays. These bays were focused areas because: (1) San Pedro harbor, with its ports of Los Angeles and Long Beach, is the busiest port in the U.S. and ranks 3rd in the world and (2) San Diego Harbor is one of the largest Naval ports, serving a diverse mix of commercial, recreational and military traffic, including more than 190 cruise ships annual. Maintaining harbor and port security has added complexity for these Southern California bays, because of the close proximity to the Mexican border. We will present in situ optical data and hyperspectral aircraft ocean color imagery from these two bays and compare and contrast the differences and similarities. This preliminary data will then be used to discuss how water transparency and diver visibility predictions improve harbor and port security.

    Inner ear barotrauma (IEBt) constitutes a spectrum of pressure-related pathology in the inner ear, with antecedent middle ear barotrauma (MEBt) common. IEBt includes perilymph fistula, intralabyrinthine membrane tear, inner ear haemorrhage and other rarer pathologies. Following a literature search, the pathophysiology, diagnosis, and treatment of IEBt in divers and best-practice recommendations for returning to diving were reviewed. Sixty-nine papers/texts were identified and 54 accessed. Twenty-five case series (majority surgical) provided guidance on diagnostic pathways; nine solely reported divers. IEBt in divers may be difficult to distinguish from inner ear decompression sickness (IEDCS), and requires dive-risk stratification and careful interrogation regarding diving-related ear events, clinical assessment, pure tone audiometry, a fistula test and electronystagmography (ENG). Once diagnosed, conservative management is the recommended first line therapy for IEBt. Recompression does not appear to cause harm if the diagnosis (IEBt vs IEDCS) is doubtful (limited case data). Exploratory surgery is indicated for severe or persisting vestibular symptoms or hearing loss, deterioration of symptoms, or lack of improvement over 10 days indicating significant pathology. Steroids are used, but without high-level evidence. It may be possible for divers to return to subaquatic activity after stakeholder risk acceptance and informed consent, provided: (1) sensorineural hearing loss is stable and not severe; (2) there is no vestibular involvement (via ENG); (3) high-resolution computed tomography has excluded anatomical predilection to IEBt and (4) education on equalising techniques is provided. There is a need for a prospective data registry and controlled trials to better evaluate diagnostic and treatment algorithms.

    During scuba diving, the circulatory system is stressed by an elevated partial pressure of oxygen while the diver is submerged and by decompression-induced gas bubbles on ascent to the surface. This diving-induced stress may trigger decompression illness, but the majority of dives are asymptomatic. In this study we have mapped divers' blood transcriptomes with the aim of identifying genes, biological pathways, and cell types perturbed by the physiological stress in asymptomatic scuba diving. Ten experienced divers abstained from diving for >2 wk before performing a 3-day series of daily dives to 18 m depth for 47 min while breathing compressed air. Blood for microarray analysis was collected before and immediately after the first and last dives, and 10 matched nondivers provided controls for predive stationary transcriptomes. MetaCore GeneGo analysis of the predive samples identified stationary upregulation of genes associated with apoptosis, inflammation, and innate immune responses in the divers, most significantly involving genes in the TNFR1 pathway of caspase-dependent apoptosis, HSP60/HSP70 signaling via TLR4, and NF-κB-mediated transcription. Diving caused pronounced shifts in transcription patterns characteristic of specific leukocytes, with downregulation of genes expressed by CD8+ T lymphocytes and NK cells and upregulation of genes expressed by neutrophils, monocytes, and macrophages. Antioxidant genes were upregulated. Similar transient responses were observed after the first and last dive. The results indicate that sublethal oxidative stress elicits the myeloid innate immune system in scuba diving and that extensive diving may cause persistent change in pathways controlling apoptosis, inflammation, and innate immune responses.

    We developed a novel integrated technology for diver-operated surveying of shallow marine ecosystems. The HyperDiver system captures rich multifaceted data in each transect: hyperspectral and color imagery, topographic profiles, incident irradiance and water chemistry at a rate of 15-30 m(2) per minute. From surveys in a coral reef following standard diver protocols, we show how the rich optical detail can be leveraged to generate photopigment abundance and benthic composition maps. We applied machine learning techniques, with a minor annotation effort (<2% of pixels), to automatically generate cm-scale benthic habitat maps of high taxonomic resolution and accuracy (93-97%). The ability to efficiently map benthic composition, photopigment densities and rugosity at reef scales is a compelling contribution to modernize reef monitoring. Seafloor-level hyperspectral images can be used for automated mapping, avoiding operator bias in the analysis and deliver the degree of detail necessary for standardized environmental monitoring. The technique can deliver fast, objective and economic reef survey results, making it a valuable tool for coastal managers and reef ecologists. Underwater hyperspectral surveying shares the vantage point of the high spatial and taxonomic resolution restricted to field surveys, with analytical techniques of remote sensing and provides targeted validation for aerial monitoring.

    Microsensors are powerful tools for microenvironment studies, however their use has often been restricted to laboratory applications due to the lack of adequate equipment for in situ deployments. Here we report on new features, construction details, and examples of applications of an improved diver-operated motorized microsensor profiler for underwater field operation to a water depth of 25 m. The new motorized profiler has a final precision of 5 microm, and can accommodate amperometric Clark-type microsensors for oxygen and hydrogen sulfide, potentiometric microsensors (e.g., for pH, Ca2+), and fiber-optic irradiance microsensors. The profiler is interfaced by a logger with a signal display, and has pushbuttons for underwater operation. The system can be pre-programmed to autonomous operation or interactively operated by divers. Internal batteries supply power for up to 24 h of measurements and 36 h of data storage (max. 64 million data points). Two flexible stands were developed for deployment on uneven or fragile surfaces, such as coral reefs. Three experimental pilot studies are presented, where (1) the oxygen distribution in a sand ripple was 3-D-mapped, (2) the microenvironment of sediment accumulated on a stony coral was studied, and (3) oxygen dynamics during an experimental sedimentation were investigated. This system allows SCUBA divers to perform a wide array of in situ measurements, with deployment precision and duration similar to those possible in the laboratory.

  10. Noise exposure of commercial divers in the Norwegian Sector of the North Sea.

    It is well known that exposure to high noise levels can adversely affect human hearing. Legislation exists in Europe to control or restrict the level of noise to which employees may be exposed during the course of their work. While the noise levels to which a worker may be exposed is well defined in air, human sensitivity to noise is different in high-pressure and mixed-gas conditions. Relatively little research exists to define human hearing in these circumstances, and few measurements exist of the levels of noise to which divers working in these conditions are exposed. A study using specially designed equipment has been undertaken in Norwegian waters to sample the noise levels present during typical saturation dives undertaken by commercial divers working in the Norwegian oil and gas industry. The divers were working in heliox at depths of 30 msw and 120 msw. It found noise levels were generally dominated by self-noise: flow noise while breathing and communications. The noise levels, both when corrected for the difference in hearing sensitivity under pressure in mixed gas and uncorrected, would exceed legislated limits for noise exposure in a working day without the use of noisy tools.

    Changing ambient pressure can lead to medical conditions in body cavities filled with air. Intraoral pain elicited by changes in pressure is referred to as barodontalgia. Dental barotraumas are defined as pressure-induced damages of teeth and restorations. The pathophysiologic background so far is not completely clear. The present study deals with dental and orofacial symptoms which can occur as a result of pressure variations. With the aid of cantonal administrations, diving associations, and tunnel construction firms, 520 pressure-exposed individuals (499 scuba/ professional divers, 21 caisson workers operating at excess pressure) were questioned regarding dental problems. A personal interview was conducted with affected individuals. Problems in the dental area were experienced by 15% of all respondents. Toothaches were suffered by 10.2% of the participants. Tooth injuries occurred in 6.3% of all interviewees (26 fractured amalgam restorations, 4 crown fractures, 3 losses of tooth fragments). A proportion of 11.3% among the respondents complained about temporomandibular joint problems or mucosal irritations (for example aphthae) related to the mouthpieces. Barotraumas outside the dental area were incurred by 31.9% of the divers. Of these, 69.9% concerned the ears and 65.6% occurred during the descent. Based on the results obtained from the survey and taking into account the current literature, recommendations for the prevention of barotraumas in divers and caisson workers were prepared. Diagnostic exclusion of dental pathologies and avoidance of retentive reconstruction materials are important factors for the prevention of barodontalgias and dental barotraumas.

  17. Correlation between Patent Foramen Ovale, Cerebral "Lesions" and Neuropsychometric Testing in Experienced Sports Divers: Does Diving Damage the Brain?

    PubMed

    Balestra, Costantino; Germonpré, Peter

    2016-01-01

    SCUBA diving exposes divers to decompression sickness (DCS). There has been considerable debate whether divers with a Patent Foramen Ovale of the heart have a higher risk of DCS because of the possible right-to-left shunt of venous decompression bubbles into the arterial circulation. Symptomatic neurological DCS has been shown to cause permanent damage to brain and spinal cord tissue; it has been suggested that divers with PFO may be at higher risk of developing subclinical brain lesions because of repeated asymptomatic embolization of decompression-induced nitrogen bubbles. These studies however suffer from several methodological flaws, including self-selection bias. We recruited 200 volunteer divers from a recreational diving population who had never suffered from DCS; we then randomly selected 50 of those for further investigation. The selected divers underwent brain Magnetic Resonance Imaging to detect asymptomatic brain lesions, contrast trans-oesophageal echocardiography for PFO, and extensive neuro-psychometric testing. Neuro-psychometry results were compared with a control group of normal subjects and a separate control group for subjects exposed to neurotoxic solvents. Forty two divers underwent all the tests and are included in this report. Grade 2 Patent Foramen Ovale was found in 16 (38%) of the divers; brain Unidentified Bright Objects (UBO's) were found in 5 (11.9%). There was no association between PFO and the presence of UBO's (P = 0.693) or their size (p = 0.5) in divers. Neuropsychometric testing in divers was significantly worse from controls in two tests, Digit Span Backwards (DSB; p < 0.05) and Symbol-Digit-Substitution (SDS; p < 0.01). Compared to subjects exposed to neurotoxic solvents, divers scored similar on DSB and SDS tests, but significantly better on the Simple Reaction Time (REA) and Hand-Eye Coordination (EYE) tests. There was no correlation between PFO, number of UBO's and any of the neuro-psychometric tests. We conclude that for

    We investigate the role of networks of alliances in preventing (multilateral) interstate wars. We first show that, in the absence of international trade, no network of alliances is peaceful and stable. We then show that international trade induces peaceful and stable networks: Trade increases the density of alliances so that countries are less vulnerable to attack and also reduces countries' incentives to attack an ally. We present historical data on wars and trade showing that the dramatic drop in interstate wars since 1950 is paralleled by a densification and stabilization of trading relationships and alliances. Based on the model we also examine some specific relationships, finding that countries with high levels of trade with their allies are less likely to be involved in wars with any other countries (including allies and nonallies), and that an increase in trade between two countries correlates with a lower chance that they will go to war with each other.

    This longitudinal prospective and multi-informant study based on a three-wave research program (pregnancy, 12 months' postpartum, and 16 months' postpartum) aimed to determine the process of construction of family alliance, as assessed by the Lausanne Trilogue Play (Fivaz-Depeursinge & Corboz-Warnery, 1999). A model using parents' individual characteristics (i.e., personality traits and attachment orientations) as distal variables, coparenting as a mediator, child's temperament as a moderator, and family alliance as outcome was tested using structural equation modeling on 62 nonreferred families. Results showed that both parents' conscientiousness was positively and mothers' avoidant attachment and fathers' anxious attachment were negatively and indirectly (via coparenting) associated with the family alliance. The discussion underlines mothers' and fathers' different roles and the importance of coparenting as a core mechanism in the development of family alliance.

  9. Alliance: a common factor of psychotherapy modeled by structural theory.

    Tschacher, Wolfgang; Haken, Hermann; Kyselo, Miriam

    2015-01-01

    There is broad consensus that the therapeutic alliance constitutes a core common factor for all modalities of psychotherapy. Meta-analyses corroborated that alliance, as it emerges from therapeutic process, is a significant predictor of therapy outcome. Psychotherapy process is traditionally described and explored using two categorically different approaches, the experiential (first-person) perspective and the behavioral (third-person) perspective. We propose to add to this duality a third, structural approach. Dynamical systems theory and synergetics on the one hand and enactivist theory on the other together can provide this structural approach, which contributes in specific ways to a clarification of the alliance factor. Systems theory offers concepts and tools for the modeling of the individual self and, building on this, of alliance processes. In the enactive perspective, the self is conceived as a socially enacted autonomous system that strives to maintain identity by observing a two-fold goal: to exist as an individual self in its own right (distinction) while also being open to others (participation). Using this conceptualization, we formalized the therapeutic alliance as a phase space whose potential minima (attractors) can be shifted by the therapist to approximate therapy goals. This mathematical formalization is derived from probability theory and synergetics. We draw the conclusion that structural theory provides powerful tools for the modeling of how therapeutic change is staged by the formation, utilization, and dissolution of the therapeutic alliance. In addition, we point out novel testable hypotheses and future applications.

    In this presentation, we will introduce Japanese contributions to the data archives for international collaborations. In Japan, the importance of planetary data archive was not recognized enough until early in 2000's. While NASA and ESA started their collaborations to their archives: PDS and PSA, and tried to make the new standard, JAXA was looking for the way of contributions because Japan did not have own data and archiving policy. The activities of NASA and ESA extended to the international collaborations, and International Planetary Data Alliance was established. JAXA had an opportunity to join the IPDA as an agency member. One of the contributions, the IPDA chairman was undertaken by Japanese member. The projects in IPDA were managed and were proceeded successfully during the term. For the technical part, JAXA is making several pilot systems to share planetary data. Planetary Data Access Protocol, PDAP, developed by IPDA, is implemented in JAXA's system, and provides a search system for Hayabusa and Kaguya (SELENE) data. Not only for Japanese data, but also Apollo's seismic data archives are prepared for scientific communities. The seismic data on the moon has not been measured for a long time, and Apollo's data are still precious and should be archived together with much information. The contributions to planetary data archives has just started and continues as a member of IPDA.

    The Sequestration Training, Outreach, Research and Education (STORE) Alliance at The University of Texas at Austin completed its activity under Department of Energy Funding (DE- FE0002254) on September 1, 2013. The program began as a partnership between the Institute for Geophysics, the Bureau of Economic Geology and the Petroleum and Geosystems Engineering Department at UT. The initial vision of the program was to promote better understanding of CO2 utilization and storage science and engineering technology through programs and opportunities centered on training, outreach, research and technology transfer, and education. With over 8,000 hrs of formal training and education (and almost 4,500 of those hours awarded as continuing education credits) to almost 1,100 people, STORE programs and activities have provided benefits to the Carbon Storage Program of the Department of Energy by helping to build a skilled workforce for the future CCS and larger energy industry, and fostering scientific public literacy needed to continue the U.S. leadership position in climate change mitigation and energy technologies and application. Now in sustaining mode, the program is housed at the Center for Petroleum and Geosystems Engineering, and benefits from partnerships with the Gulf Coast Carbon Center, TOPCORP and other programs at the university receiving industry funding.

    The Puerto Rico Energy Affairs Administration (PREAA) is actively engaged in the implementation of existing public policy for the conservation of energy and promotion of renewable energy to reduce consumer’s costs and reduce environmental impact. Puerto Rico is an island in where no own reserves of gas, oil or coal exists. This severe dependence in on foreign oil is reflected in the higher cost of electricity in Puerto Rico, which is significantly higher than most of the United States. Therefore, public energy policy of Puerto Rico places emphasis on diversification of energy sources and the use of renewable energy technologies. The Wind energy Alliance for the Sustainable Development project focused on the formation of a wind energy working group to educate and promote wind energy technologies; at the same time the evaluating the viability of wind energy in Puerto Rico. The educational outreach was performed through a series of wind energy workshops where interested parties such as, installers, sellers, engineers, general public even opposing groups participate from the activities.

    Associations, Alliances, and Allies, a seminar and workshop sponsored by the Electric Power Research Institute, was held in Memphis, Tennessee, April 10--11, 1991. The focus of the meeting was relationships forged between electric utilities and trade allies that sell residential heat pumps. one hundred and seven representatives of electric utilities, dealer/contractors, manufacturers, and consultants attended. Electric utility trade ally programs run the gamut from coop advertising to heat pump association to elaborate technician training programs. All utility participants recognize the important programs, since it is the trade ally who sells, installs, and services heat pumps, while it is the electric utility who gets blamed if the heat pumps fail to operate properly or are inefficient. Heat pumps are efficient and effective, but their efficiency and effectiveness depends critically upon the quality of installation and maintenance. A utility can thus help to ensure satisfied customers and can also help to achieve its own load shape objectives by working closely with its trade allies, the dealers, contractors, manufacturers, and distributors. Attendees spent the morning sessions of the two day meeting in plenary sessions, hearing about utility and dealer heat pump programs and issues. Afternoon roundtable discussions provided structured forums to discuss: Advertising; Heat pump association startup and operation; Rebates and incentives; Technician training school and centers; Installation inspection and dealer qualification; and Heat pump association training. These proceedings report on the papers presented in the morning plenary sessions and summarize the main points discussed in the afternoon workshops.

    The therapeutic alliance between multidisciplinary teams and parents within youth (semi) residential psychiatry is essential for the treatment process and forms a promising process variable for Routine Outcome Monitoring (ROM). No short evaluative instrument, however, is currently available to assess parent-team alliance. In this study, the Working Alliance Inventory-Short Version (WAV-12), a widely used alliance questionnaire, was adjusted to assess parent-team alliance from both a parent and team perspective within a youth residential setting. Psychometric properties, including factor structure and validity of the subscales, were explored. A sample of youth with mainly complex developmental disorders admitted to 11 inpatient and day patient units of a child and adolescent psychiatric institute participated in this study. The case manager involved with the youth and the primary caregiver of 87 youth completed the revised WAV-12 (WAV-12R). The team version of the WAV-12R showed a good fit to the original conceptualized model, and distinguished Bond, Task and Goal scales. For the parents' version an adjusted model with Insight, Bond and combined Task/Goal scales had the best fit. The reliability and validity of the scales were shown to be good. This paper presents preliminary evidence that the parent and treatment team versions of the WAV-12R are psychometrically sound for assessing parent-team alliance within youth (semi) residential psychiatry in the Netherlands. The team and parents' versions of the WAV-12R are recommended instruments to complement outcome measures in ROM.

    Therapeutic alliance is a well-recognized predictor of patient outcomes within psychological therapy. It has not been applied to obesity interventions, and Bordin's theoretical framework shows particular relevance to the management of obesity in primary health care. This cross-sectional study of a weight management programme in general practice aimed to determine if therapeutic alliance was associated with patient outcomes. The Working Alliance Inventory short revised version (WAI-SR) was administered to 23 patients and 11 general practitioners (GPs) at the end of a 6-month weight management programme. Use of the WAI-SR indicated that the strength of therapeutic alliance varied between different patient-GP relationships in this pilot intervention. A robust therapeutic alliance was strongly associated with patient engagement in the weight management programme indicated by number of appointments. It was also associated with some general health and quality of life outcomes. These are promising results that require confirmation with larger studies in primary health care. The measurement of therapeutic alliance using the WAI-SR may predict patient attendance and outcomes in obesity interventions in primary healthcare settings.

  19. Alliances for Undergraduate Research in the Geosciences Through Collaborative Recruitment

    2006-12-01

    Undergraduate research is a key strategy for encouraging students to pursue graduate school and careers in science end engineering. In the geosciences, where participation by members of underrepresented groups is among the lowest of any science field, these programs must continue and strengthen their efforts to engage students from historically underrepresented groups. A significant limitation on our ability to engage students from historically underrepresented groups comes from the expense, in terms of time and resources, of promoting these career options to talented undergraduates considering a host of STEM careers. Another hurdle is our ability to match students with research projects tailored to their interests. Further complicating this is the challenge of matching students who have culturally motivated geographic constraints—for example, Native students who seek to serve their local community—to relevant opportunities. As a result, we believe that a number of highly qualified students never fully consider careers in the geosciences. To address these obstacles, we propose an alliance of undergraduate research programs in the geosciences. In this model, all members of the alliance would share recruiting, and students would submit a single application forwarded to all alliance members. The Alliance could offer applicants multiple research opportunities, from across the alliance, tailored to fit the applicant's needs and interests. This strategy has proven very effective in other fields; for example, the Leadership Alliance allows 32 member institutions to offer internships and fellowships through one central application process. SOARS and RESESS, programs in atmospheric science and geophysics, respectively, have done this co-recruiting for two years. There are many benefits to this type of alliance. First, it would allow programs to leverage and coordinate their recruiting investments. From our experience with SOARS and RESESS, much of the effort in

    The International Planetary Data Alliance (IPDA) is a close association of partners with the aim of improving the quality of planetary science data and services to the end users of space based instrumentation. The specific mission of the IPDA is to facilitate global access to, and exchange of, high quality scientific data products managed across international boundaries. Ensuring proper capture, accessibility and availability of the data is the task of the individual member space agencies. The IPDA is focused on developing an international standard that allows discovery, query, access, and usage of such data across international planetary data archive systems. While trends in other areas of space science are concentrating on the sharing of science data from diverse standards and collection methods, the IPDA concentrates on promoting governing data standards that drive common methods for collecting and describing planetary science data across the international community. This approach better supports the long term goal of easing data sharing across system and agency boundaries. An initial starting point for developing such a standard will be internationalization of NASA's Planetary Data System's (PDS) PDS4 standard. The IPDA was formed in 2006 with the purpose of adopting standards and developing collaborations across agencies to ensure data is captured in common formats. It has grown to a dozen member agencies represented by a number of different groups through the IPDA Steering Committee. Member agencies include: Armenian Astronomical Society, China National Space Agency (CNSA), European Space Agency (ESA), German Aerospace Center (DLR), Indian Space Research Organization (ISRO), Italian Space Agency (ASI), Japanese Aerospace Exploration Agency (JAXA), National Air and Space Administration (NASA), National Centre for Space Studies (CNES), Space Research Institute (IKI), UAE Space Agency, and UK Space Agency.

    Artificial reefs are increasingly used worldwide as a method for managing recreational diving since they have the potential to satisfy both conservation goals and economic interests. In order to help maximize their utility, further information is needed to drive the design of stimulating resources for scuba divers. We used a questionnaire survey to explore divers’ perceptions of artificial reefs in Barbados. In addition, we examined reef resource substitution behaviour among scuba divers. Divers expressed a clear preference for large shipwrecks or sunken vessels that provided a themed diving experience. Motives for diving on artificial reefs were varied, but were dominated by the chance of viewing concentrated marine life, increased photographic opportunities, and the guarantee of a ‘good dive’. Satisfaction with artificial reef diving was high amongst novices and declined with increasing experience. Experienced divers had an overwhelming preference for natural reefs. As a management strategy, our results emphasize the capacity of well designed artificial reefs to contribute towards the management of coral reef diving sites and highlight a number of important areas for future research. Suggested work should validate the present findings in different marine tourism settings and ascertain support of artificial reefs in relationship to level of diver specialization. PMID:23894372

    In 2005 the National Ground Intelligence Center (NGIC) proposed that the PATTON Alliance provide assistance in evaluating and obtaining the Integrated Gazetteer Database (IGDB), developed for the Naval Space Warfare Command Research group (SPAWAR) under Advance Research and Development Activity (ARDA) funds by MITRE Inc., fielded to the text-based search tool GeoLocator, currently in use by NGIC. We met with the developers of GeoLocator and identified their requirements for a better gazetteer. We then validated those requirements by reviewing the technical literature, meeting with other members of the intelligence community (IC), and talking with both the United States Geologic Survey (USGS) and the National Geospatial Intelligence Agency (NGA), the authoritative sources for official geographic name information. We thus identified 12 high-level requirements from users and the broader intelligence community. The IGDB satisfies many of these requirements. We identified gaps and proposed ways of closing these gaps. Three important needs have not been addressed but are critical future needs for the broader intelligence community. These needs include standardization of gazetteer data, a web feature service for gazetteer information that is maintained by NGA and USGS but accessible to users, and a common forum that brings together IC stakeholders and federal agency representatives to provide input to these activities over the next several years. Establishing a robust gazetteer web feature service that is available to all IC users may go a long way toward resolving the gazetteer needs within the IC. Without a common forum to provide input and feedback, community adoption may take significantly longer than anticipated with resulting risks to the war fighter.

  4. Strategic Classification and Examination of the Development of Current Airline Alliance Activities

    2002-01-01

    Previous research argues that despite the fact that strategic alliances have become an important feature of the world airline industry, little rigorous analysis has been done on the effects of these alliances. This is partially because there is a lack of precise definitions to specify different types of airline alliances in the literature. This research identifies several categories of airline alliances through a strategic classification of the current alliance activities involving the major airlines for the period 1989 to 1999. The classification enables this research to examine how strategic alliance activities are evolving, particularly to compare how airlines in North America, the European Union and the Asia Pacific region have committed to different alliances. Findings show that there is a significant difference between the number and scope of alliances adopted in the three aviation markets. These findings facilitate research to further analyse the impact of market liberalization on various formations of strategic airline alliances.

    This study examined the temporal stability and cross-informant agreement on multiple perspectives of child and caregiver alliance with therapists in usual care psychotherapy. Baseline predictors of alliance were also examined. Children with disruptive behavior problems (n = 209) and their caregivers were followed for up to 16 months after initiating psychotherapy at a community-based clinic. Alliance was rated by children, caregivers, and therapists every 4 months for as long as families participated in treatment. Repeated-measures analyses using linear mixed models with random intercepts were conducted to determine whether child and caregiver alliance differed across time, as well to examine factors associated with each perspective on alliance. Intraclass correlations between child, caregiver, and therapist reports of alliance were also examined. Alliance was rated relatively high overall across perspectives. Clients (children and caregivers) tended to report the strongest and most stable alliance, while therapists reported the weakest alliance and perceived deteriorations in child alliance over time. Inter-informant agreement was variable for child and caregiver alliance; agreement was moderate between clients and therapists. Several predictors of alliance emerged, including child gender, anxiety diagnosis, caregiver race/ethnicity, and therapist experience. This study provides methodological information about reports of therapeutic alliance across time and informants that can inform current efforts to understand the alliance-outcome association.

    Although past research has demonstrated a positive relationship between the therapeutic alliance (TA) and improved drinking outcomes, specific aspects of the alliance have received less attention. In this study, we examined the association between alliance characteristics during treatment and 4-month follow-up drinking reports. Sixty-five treatment-seeking alcohol dependent clients who participated in 12 weeks of individual outpatient treatment provided weekly TA ratings during treatment and reported on pretreatment, during treatment, and posttreatment alcohol use. Latent profile analysis was conducted to discern distinct profiles of client and therapist ratings of therapeutic alliance with similar alliance characteristics. TA profiles were based on clients' and therapists' mean alliance rating, minimum alliance rating, maximum alliance rating, the range of alliance ratings, and the difference in session number between maximum and minimum alliance ratings. One- through 4-class models were fit to the data. Model fit was judged by comparative fit indices, substantive interpretability, and parsimony. Wald tests of mean equality determined whether classes differed on follow-up percentage of days abstinent (PDA) at 4-months posttreatment. Three-profile solutions provided the best fit for both client and therapist ratings of the therapeutic alliance. Client alliance rating profiles predicted drinking in the follow-up period, but therapist rating profiles did not. These results suggest that distinct profiles of the therapeutic alliance can be identified and that client alliance rating profiles are associated with frequency of alcohol use following outpatient treatment.

    While past research has demonstrated a positive relationship between the therapeutic alliance (TA) and improved drinking outcomes, specific aspects of the alliance have received less attention. In this study, we examined the association between alliance characteristics during treatment and 4-month follow-up drinking reports. 65 treatment-seeking alcohol dependent clients who participated in 12 weeks of individual outpatient treatment provided weekly TA ratings during treatment and reported on pre-treatment, during treatment, and post-treatment alcohol use. Latent profile analysis was conducted to discern distinct profiles of client and therapist ratings of therapeutic alliance with similar alliance characteristics. TA profiles were based on clients’ and therapists’ mean alliance rating, minimum alliance rating, maximum alliance rating, the range of alliance ratings, and the difference in session number between maximum and minimum alliance ratings. 1- through 4- class models were fit to the data. Model fit was judged by comparative fit indices, substantive interpretability, and parsimony. Wald tests of mean equality determined whether classes differed on follow-up percentage of days abstinent (PDA) at 4 months posttreatment. 3-profile solutions provided the best fit for both client and therapist ratings of the therapeutic alliance. Client alliance rating profiles predicted drinking in the follow-up period, but therapist rating profiles did not. These results suggest that distinct profiles of the therapeutic alliance can be identified and that client alliance rating profiles are associated with frequency of alcohol use following outpatient treatment.

    Typically, ventilation is tightly matched to CO2 production. However, in some cases CO2 is retained (SCUBA diving). One factor behind hypoventilation in divers may be low respiratory CO2 sensitivity. If this is due to inadequate respiratory muscle performance it might be remedied by respiratory muscle training (RMT). We retrospectively investigated respiratory CO2 sensitivity prior to and after RMT in several groups of SCUBA divers. CO2 sensitivity (slope of expired ventilation as a function of inspired PCO2) was measured with a rebreathing technique in 35 subjects with diving experience. RMT consisted of either isocapnic hyperventilation or intermittent vital capacity breaths (twice/minute) against spring loaded breathing valves imposing static and resistive loads generating average inspiratory pressures of approximately 40 cmH2O and expiratory pressures of approximately 47 cmH2O; RMT was performed 30 min/day, 3 or 5 days/week for 4 weeks. Based on pre-RMT CO2 sensitivity the subjects were divided into three groups: low sensitivity: < 2 l/min/mmHg PCO2, normal: 2-4 l/min/mmHg, and high sensitivity: > 4 l/min/mmHg of inspired PCO2. The normal group had a Pre-RMT CO2 sensitivity of 2.88 +/- 0.60 and a post RMT sensitivity of 2.51 +/- 0.88 l/min/mmHg (Mean +/- SD, n = 19, p = n.s). Response in low sensitivity subjects increased from 1.41 +/- 0.32 to 2.27 +/- 0.53 (n = 10, p = 0.002,) while in the high sensitivity group it decreased from 5.41 +/- 1.25 to 2.90 +/- 0.32 l/min/mmHg (n = 6, p = 0.003). These preliminary findings showed that 46% of the subjects had abnormal sensitivity, and suggest that RMT may normalize it in hypo- and hyper-ventilating divers. If the present results are verified, RMT may be an effective means of enhancing safety in CO2 retaining divers.

  9. Precision, accuracy, and application of diver-towed underwater GPS receivers.

    Diver-towed global positioning systems (GPS) handhelds have been used for a few years in underwater monitoring studies. We modeled the accuracy of this method using the software KABKURR originally developed by the University of Rostock for fishing and marine engineering. Additionally, three field experiments were conducted to estimate the precision of the method and apply it in the field: (1) an experiment of underwater transects from 5 to 35 m in the Southern Chile fjord region, (2) a transect from 5 to 30 m under extreme climatic conditions in the Antarctic, and (3) an underwater tracking experiment at Lake Ranco, Southern Chile. The coiled cable length in relation to water depth is the main error source besides the signal quality of the GPS under calm weather conditions. The forces used in the model resulted in a displacement of 2.3 m in a depth of 5 m, 3.2 m at a 10-m depth, 4.6 m in a 20-m depth, 5.5 m at a 30-m depth, and 6.8 m in a 40-m depth, when only an additional 0.5 m cable extension was used compared to the water depth. The GPS buoy requires good buoyancy in order to keep its position at the water surface when the diver is trying to minimize any additional cable extension error. The diver has to apply a tensile force for shortening the cable length at the lower cable end. Repeated diving along transect lines from 5 to 35 m resulted only in small deviations independent of water depth indicating the precision of the method for monitoring studies. Routing of given reference points with a Garmin 76CSx handheld placed in an underwater housing resulted in mean deviances less than 6 m at a water depth of 10 m. Thus, we can confirm that diver-towed GPS handhelds give promising results when used for underwater research in shallow water and open a wide field of applicability, but no submeter accuracy is possible due to the different error sources.

  10. Fasting improves static apnea performance in elite divers without enhanced risk of syncope.

    In competitive apnea divers, the nutritional demands may be essentially different from those of, for example, endurance athletes, where energy resources need to be maximised for successful performance. In competitive apnea, the goal is instead to limit metabolism, as the length of the sustainable apneic period will depend to a great extent on minimising oxygen consumption. Many but not all elite divers fast before performing static apnea in competition. This may increase oxygen consumption as mainly lipid stores are metabolised but could also have beneficial effects on apneic duration. Our aim was to determine the effect of over-night fasting on apnea performance. Six female and seven male divers performed a series of three apneas after eating and fasting, respectively. The series consisted of two 2-min apneas spaced by 3 min rest and, after 5 min rest, one maximal effort apnea. Apneas were performed at supine rest and preceded by normal respiration and maximal inspiration. Mean (± SD) time since eating was 13 h (± 2 h 43 min) for the fasting and 1 h 34 min (± 33 min) for the eating condition (P < 0.001). Mean blood glucose was 5.1 (± 0.4) mmol/L after fasting and 5.9 (± 0.7) mmol/L after eating (P<0.01). Lung volumes were similar in both conditions (NS). For the 2-min apneas, nadir SaO2 during fasting was 95 (± 1)% and 92 (± 2)% (P < 0.001) on eating and ETCO2 was lower in the fasting condition (P < 0.01) while heart rate (HR) during apnea was 74 (± 10) bpm for fasting and 80 (± 10) bpm for eating conditions (P < 0.01). Maximal apnea durations were 4 min 41 s (± 43 s) during fasting and 3 min 51 s (± 37 s) after eating (P < 0.001), and time without respiratory contractions was 31 s (25%) longer after fasting (P < 0.01). At maximal apnea termination, SaO2 and ETCO2 were similar in both conditions (NS) and apneic HR was 63 (± 9) bpm for fasting and 70 (± 10) bpm for eating (P < 0.01). The 22% longer apnea duration after fasting with analogous end apnea

    This is the first study to explore the relationship between aspects of a therapists' personal therapy and the subsequent psychotherapy process and outcome they perform. The participants were 14 graduate clinicians with various experiences in personal therapy, who treated 54 outpatients engaged in short-term psychodynamic psychotherapy at a university-based community clinic. Results demonstrated non-significant relationships between the duration of personal therapy as well as a graduate clinician's overall alliance in their personal therapy with alliance ratings made by themselves as therapists and their patients, as well as the number of psychotherapy sessions attended by patients. However, the clinician's personal therapy alliance was significant and positively related to their patients' rating of outcome. Additionally, a significant negative correlation was observed between the degree of perceived helpfulness in their personal therapy and how these clinicians rated alliances, as the therapist, with their patients. The current findings suggest a relationship between a clinician's personal therapy alliance and the outcome of treatments they conduct. Implications for clinical training and practice as well as future research are discussed. While graduate clinician's personal therapy alliance was not significantly related to their patients' ratings of alliance, it was related to their patients' ratings of outcome. Trainee satisfaction with or quality of their personal therapy may be a more relevant than the amount or duration of their treatment in regard to the process and outcomes of their patients. The findings from retrospective clinician surveys on the helpfulness of their personal therapy may not be entirely consistent with empirical examination of these issues. The relation of personal therapy and outcome may work through improving the therapist's level of adaptive functioning (i.e., psychological-relational-emotional health) and future research should examine

    Premarital (and general relationship) education programs, as a prevention method, have been shown to have a positive effect on marital quality and can prevent divorce. However, it is unclear whether these positive effects are consistent across leaders who conduct premarital education programs. Examining the variability in relationship outcomes attributed to the leaders of premarital education programs, and the role of general therapeutic factors such as working alliance in explaining relationship outcomes, may help increase the effectiveness of these programs. Accordingly, this study examined 31 leaders who trained 118 couples (236 attendees) in a randomized clinical trial of PREP, a research-based and empirically supported premarital education program being compared to a treatment as usual track. The results demonstrated that couples’ relationship outcomes from pre to post training varied based on the leader who provided the premarital education training. Both training in PREP and aggregated leader working alliance quality (as rated by attendees) explained variability between leaders in change in attendees’ observed negative and positive communication. Leaders’ aggregated working alliance quality also explained change in relationship satisfaction. Additionally, attendees’ ratings of their leaders’ working alliance predicted change in their relationship satisfaction and confidence, and attendees had higher positive communication when they reported better working alliance with their leader.

    The vast majority of freshwater cave diving in Australia occurs within the limestone caves of the Gambier karst in the south-east of South Australia. The incidence of decompression illness (DCI) in cave divers is presumed to be higher than open-water recreational divers because of the greater depths involved, but has not previously been reported. Our aim was to determine the incidence of DCI in cave divers, the patterns of diving and the outcome of hyperbaric treatment. This was a retrospective cohort study of cave divers with DCI presenting to the Royal Adelaide Hospital or The Alfred Hospital over a 10-year period between 2002 and 2012. We reviewed case notes of cave divers who were treated for DCI after diving in the Mt Gambier karst. As there are no records of the number of dives performed during the study period we generated a denominator for the incidence of DCI by extrapolating available data and making a number of assumptions about the number of dives per dive permit issued. Sixteen patients were treated for DCI during the study period. The precipitating dive was a single deep decompression dive in seven cases, multiday repetitive dive sequences in eight and a non-decompression dive in one. Three of the 16 cases of DCI involved dives in excess of 90 metres' fresh water (mfw) using trimix. As the total estimated number of dives in the study period was approximately 57,000 the incidence of DCI in Australian cave divers was estimated to be 2.8:10,000 (0.028%). It is possible that the overall incidence of DCI is as high as 0.05%, and even higher when dives to depths greater than 90 mfw are involved. The estimated incidence of DCS in this series is lower than expected but consistent with other series describing DCI in cold-water recreational diving.

    In the first three decades of life, more individuals in the USA die from injuries and violence than from any other cause. Millions more people survive and are left with physical, emotional, and financial problems. Injuries and violence are not accidents; they are preventable. Prevention has a strong scientific foundation, yet efforts are not fully implemented or integrated into clinical and community settings. In this Series paper, we review the burden of injuries and violence in the USA, note effective interventions, and discuss methods to bring interventions into practice. Alliances between the public health community and medical care organisations, health-care providers, states, and communities can reduce injuries and violence. We encourage partnerships between medical and public health communities to consistently frame injuries and violence as preventable, identify evidence-based interventions, provide scientific information to decision makers, and strengthen the capacity of an integrated health system to prevent injuries and violence.

    This study compared remote underwater video and traditional direct diver observations to assess reef fish feeding impact on benthos across multiple functional groups within different trophic categories (e.g. herbivores, zoobenthivores and omnivores) and in two distinct reef systems: a subtropical rocky reef and a tropical coral reef. The two techniques were roughly equivalent, both detecting the species with higher feeding impact and recording similar bite rates, suggesting that reef fish feeding behaviour at the study areas are not strongly affected by the diver's presence.

    Investigation of the aerial parts of two Spanish members of the Asteriscus alliance, Asteriscus graveolens subsp. stenophyllus and Asteriscus schultzii, afforded four new sesquiterpene lactones containing a humulene skeleton (1-4) and one new sesquiterpene lactone of the asteriscanolide type (5). Their chemical structures were determined on the basis of the HRMS and from 1D and 2D NMR spectroscopic studies. Both species showed different profiles of sesquiterpenoid constituents. A. schultzii did not show humulene or asteriscane sesquiterpenes, suggesting a resemblance to the genus Pallenis, another member of the Asteriscus alliance. A literature review on chemical isolates from the Asteriscus alliance supported the placement of A. schultzii in the genus Pallenis. The isolated components (1-5) were assessed for cytotoxicity against the HL-60 and MOLT-3 leukemia cell lines, with compound 1 showing activity in both biological assays (IC50 value range 4.1-5.4 μM).

    2012-03-01

    Just as many relationships are susceptible to the distorting and distancing effects of stigmatization, so are therapist-parent relationships, particularly in instances where children/youth present with significant mental illness. Therapist awareness and attunement to the dynamics of stigma are critical to the development of engaged therapist-parent alliances, and therapist-parent alliances are key to successful child/youth psychotherapy. Intersubjectivity theory offers a useful lens by which to understand stigma dynamics as mutually reinforced, "co-constructed" experiences between therapists and parents. Applying this perspective provides direction for therapists to work in ways that recognize and reduce the negative impact of stigma dynamics on this important alliance.

    The therapeutic alliance in individual and group psychotherapy is associated with treatment outcomes for a variety of disorders. However, debate persists about the centrality of the alliance in determining positive outcomes. We examined the alliance-outcome relationship across 20 sessions of emotionally focused group therapy (EFGT) for binge-eating disorder (BED). We hypothesized that (1) previous session alliance increase will predict lower subsequent session binge eating level while controlling for previous session binge eating level; and (2) previous session binge eating decline will predict higher subsequent session alliance level while controlling previous session alliance level. Participants were 118 individuals with BED who received 20 sessions of EFGT in 8 groups. Levels of binge eating and therapeutic alliance to the therapist were measured weekly. Linear growth in alliance during group therapy was associated with reduced binge eating at 6 months' posttreatment. We also found that the group's and the individual's alliance scores and binge-eating episodes were significantly associated across treatment, suggesting a mutual influence of the group's and individual's experience of the alliance with the therapist. Regarding the first hypothesis, previous session alliance increase was significantly associated with lower subsequent session binge eating. Regarding the second hypothesis, previous session binge-eating decline was not significantly related to higher subsequent session alliance. The findings provide evidence in a group therapy context for a model in which alliance change influences subsequent symptom levels, but not the other way around. (PsycINFO Database Record

    The roles of involuntary breathing movements (IBMs) and cerebral oxygen delivery in the tolerance to extreme hypoxemia displayed by elite breath-hold divers are unknown. Cerebral blood flow (CBF), arterial blood gases (ABGs), and cardiorespiratory metrics were measured during maximum dry apneas in elite breath-hold divers (n=17). To isolate the effects of apnea and IBM from the concurrent changes on ABG, end-tidal forcing (‘clamp') was then used to replicate an identical temporal pattern of decreasing arterial PO2 (PaO2) and increasing arterial PCO2 (PaCO2) while breathing. End-apnea PaO2 ranged from 23  to 37 mm Hg (30±7 mm Hg). Elevation in mean arterial pressure was greater during apnea than during clamp reaching +54±24% versus 34±26%, respectively; however, CBF increased similarly between apnea and clamp (93.6±28% and 83.4±38%, respectively). This latter observation indicates that during the overall apnea period IBM per se do not augment CBF and that the brain remains sufficiently protected against hypertension. Termination of apnea was not determined by reduced cerebral oxygen delivery; despite 40% to 50% reductions in arterial oxygen content, oxygen delivery was maintained by commensurately increased CBF.

    The New South Wales State Government (Australia) gazetted the Jervis Bay Marine Park (JBMP) in 1998. During the preparation of the draft zoning plan in 2000, societal data on two conflicting park user groups--recreational scuba divers and fishers (anglers)--was collected. While conflict resolution was a plan priority, other factors, such as cumulative environmental impacts of users and protection for the critically endangered grey nurse shark (Carcharias taurus), further complicated planning. Both scuba diving and angling are primary summer activities and are disproportionately concentrated around the headlands of the bay. Furthermore, shore based game-fishing was concentrated on the northern headland, where the conflict was centered. However, when the exact locations of divers and anglers were determined, there was a partial partitioning of the available space, with only a small contested overlap. To resolve conflict and maximize positive environmental outcomes, a sanctuary zone and noanchoring zone option in the draft zoning plan was sought to formalize this partition. The human dimension data proved valuable in guiding environmental management in this politically volatile situation. A baseline study conducted 11 years previously was also used to gain a limited perspective on change in user numbers. Comparison between study periods indicated dive numbers had remained similar, while the number of dive charter trips was significantly less. The numbers of anglers, for the four months compared, had doubled and tripled. The actual data used to inform management is presented and the limitations of this "best available data" approach are discussed.

    Specific adjustments to repeated extreme apnea are not fully known and understood. While a blunted ventilatory chemosensitivity to CO2 is described for elite breath-hold divers (BHDs) at rest, it is unclear whether specific adaptations affect their response to dynamic exercise. Eight elite BHDs with a previously validated decrease in CO2 chemosensitivity, 8 scuba divers (SCDs), and 8 matched control subjects were included in a study where markers of ventilatory response, Fowler's dead space, partial pressure of carbon dioxide (pCO2), and blood lactate concentrations during cycle exercise were measured. Maximal power output did not differ between the groups, but lactate threshold (θL) appeared at a significantly lowered respiratory compensation point (RCP) and at a higher VO2 for the BHDs. End-tidal (petCO2) and estimated arterial pCO2 (paCO2) were significantly higher in BHDs at θL, the RCP, and maximum exhaustion. BHDs showed a significantly (P < .01) slower breathing pattern in relation to a given tidal volume at a specific work rate. In summary, BHDs presented signs of a metabolic shift from aerobic to anaerobic energy supply, decreased chemosensitivity during exercise, and a distinct ventilatory-response pattern during cycle exercise that differs from SCDs and controls.

    Scuba diving fatalities are rare and sometimes extremely difficult to explain. A thorough forensic investigation, conducted by a qualified team, helps avoid possible later questions and doubts, family concerns and judicial matters, since a significant body of evidence is lost after the body of the victim is buried or the equipment is reused. We report about a death of a scuba diver who was drowned while diving to the depth of 30 meters. Before being assisted to the surface, the diver panicked and removed the regulator from his mouth. The technical expertise of the scuba gear and the chemical analysis of the air from the high-pressure cylinder revealed no irregularities. Homicide, suicide, nitrogen narcosis, oxygen toxicity, and regulator malfunction were ruled out as possible causes of death. The most probable cause that triggered the event was vomiting into the regulator, as confirmed nearly 4 years later by the toxicological analysis of the traces of matter found in the dry chamber of the breathing regulator. Such an analysis should be considered when investigating suspicious diving related deaths and could be undertaken even after a significant time delay if the equipment is kept properly stored.

    A 32-year-old male commercial diver was working at 7,000 feet of altitude in a municipal water tank, at a depth of 27 feet for two hours. While surfacing from a compressed-air surface-supplied dive, he exhibited loss of consciousness and neurological symptoms. He was presumptively diagnosed with arterial gas embolism, flown by pressurized aircraft to a regional medical center and treated with hyperbaric oxygen. During the U.S. Navy Treatment Table 6, new information suggested the patient's air supply had been contaminated by a continuously running engine and compressor. His admission blood was then assayed for carboxyhemoglobin (COHb), which measured 8.8% six hours after surfacing, including four hours of normobaric oxygen inhalation. His estimated COHb based on rough reported half-life calculations at the conclusion of the dive was approximately 45%. The patient's diagnosis was changed to carbon monoxide poisoning from contaminated breathing gas. Upon hospital discharge, he exhibited problems with balance and gait, nystagmus, word-finding limitations and slurred speech. Also, he had cardiac injury treated with carvedilol. When evaluating diving-related casualties, including in commercial divers, clinicians should consider carbon monoxide poisoning as a differential diagnosis.

    Background Physical activity increases the performance of the nervous system by stimulating the body’s metabolism and improving the efficiency of the ATP production system. Objectives In the present study, the effect of twenty minutes scuba diving in high depth (10m) on cognitive function and stress system activity was investigated. Methods Twelve professional scuba divers with a mean age of 23 ± 1 year, weight of 80 ± 2.5 kg and height of 1.79 ± 3.5 cm resident in the city of Mashhad participated in the test. Their cognitive functions were measured 60 min before and 20 min after diving and the data were evaluated using the PASAT software. In the present study, parameters such as general mental health, sustained attention, average response speed, and mental fatigue were measured. Moreover, in order to determine the activity of the stress system, their salivary cortisol was collected before and after diving. Results Results revealed that, the general mental health of these scuba divers was normal and it did not undergo a remarkable change after diving. Their average response speed and sustained attention had a significant decrease after scuba diving. Mental fatigue after diving increased. Also, salivary cortisol level significantly increased after diving. Conclusions According to our data, it seems that scuba diving as stress stimulant increases cortisol level and therefore reduces cognitive performance after diving. PMID:27826405

  14. Two levels of alliance formation among male bottlenose dolphins (Tursiops sp.).

    PubMed

    Connor, R C; Smolker, R A; Richards, A F

    1992-02-01

    In Shark Bay, Western Australia, male bottlenose dolphins (Tursiops sp.) cooperate in pairs and triplets to sequester and control the movements of females. We refer to this behavior as "herding" and to the male pairs and triplets as alliances. During a 25-month study (1987-1989) on the social relationships of males, we documented herding in 10 alliances. Males preferentially herded nonpregnant females likely to be in estrus. Alliance members associated with one another consistently when not herding females. Each alliance associated preferentially with one or two other alliances. Occasionally, two alliances combined and took females from another alliance or defended females against such efforts. This study documents multiple-level male alliances within a social group outside of humans.

    Physical education (PE) can help to achieve important public health goals, but is often under-prioritized and lacking in schools. To detail the actions, impact, and successes of a strategic alliance formed by three collaborating organizations to improve PE in a large California school district. Semistructured interviews with alliance members, principals, and teachers in 20 elementary schools, 3 years after the alliance formation. Interviewees reported district-level increases in priority and funding for PE and attributed improvements to the alliance's collection and dissemination of local data on the status of PE. Common goals, trust, and open communication within the alliance were seen as critical to the alliance's success. However, changes in district- or school-level accountability measures for PE were not reported. This strategic alliance succeeded in promoting district-level priority and funding for PE. Ongoing alliance work will focus on increasing accountability measures for PE, which may take longer to implement.

    2014-10-01

    The paper is concerned with dynamics of light solid in cavity with liquid subjected to rotational vibration in the external force field. New vibrational phenomenon - diving of a light cylinder to the cavity bottom is found. The experimental investigation of a horizontal annulus with a partition has shown that under vibration a light body situated in the upper part of the layer is displaced in a threshold manner some distance away from the boundary. In this case the body executes symmetric tangential oscillations. An increase of the vibration intensity leads to a tangential displacement of the body near the external boundary. This displacement is caused by the tangential component of the vibrational lift force, which appears as soon as the oscillations lose symmetry. In this case the trajectory of the body oscillatory motion has the form of a loop. The tangential lift force makes stable the position of the body on the inclined section of the layer and even in its lower part. A theoretical interpretation has been proposed, which explains stabilization of a quasi-equilibrium state of a light body near the cavity bottom in the framework of vibrational hydromechanics.

    Background Research has shown that the therapeutic alliance plays an important role in enhancing treatment outcome among individuals with a variety of disorders, including posttraumatic stress disorder (PTSD). However, the therapeutic alliance and treatment outcome has not yet been studied in dissociative disorders (DD). Objectives The current study sought to investigate the impact of alliance on treatment outcome for DD patients. Methods Data from a naturalistic, longitudinal international treatment study of DD patients and their therapists were analyzed to determine if the alliance, as reported by patients and therapists, was associated with treatment outcome. Results Patients with higher self-rated alliance had fewer symptoms of dissociation, PTSD, and general distress, as well as higher levels of therapist-rated adaptive functioning. Over time, self-rated alliance scores predicted better outcomes, after controlling for patient adaptive capacities including symptom management at the time when the alliance ratings were made. Patient-rated alliance was more strongly associated with outcome than therapist-rated alliance. Conclusion Therapists who work with DD patients should understand the importance of the alliance on treatment outcome. These findings are consistent with previous literature demonstrating the importance of developing and maintaining a strong therapeutic alliance, although the effect sizes of individuals with DD were stronger than what has been found in many other patient groups. A greater understanding of the impact of the alliance in traumatized individuals may contribute to better outcomes for these individuals. PMID:24616755

  5. Therapeutic Alliance With Depressed Adolescents: Predictor or Outcome? Disentangling Temporal Confounds to Understand Early Improvement.

    Labouliere, Christa D; Reyes, J P; Shirk, Stephen; Karver, Marc

    2015-06-04

    Psychotherapy research reveals consistent associations between therapeutic alliance and treatment outcomes in the youth literature; however, past research frequently suffered measurement issues that obscured temporal relationships between alliance and symptomatology by measuring variables later in therapy, thereby precluding examination of important early changes. The current study aimed to explore the directions of effect between alliance and outcome early in therapy with adolescents by examining associations between first- and fourth-session therapeutic alliance and symptomatology. Thirty-four adolescents (∼63% female, 38% ethnic/racial minority) participated in a school-based cognitive-behavioral therapy for adolescents with depression. Participants completed the Beck Depression Inventory at baseline and Session 4, and therapeutic alliance was coded from audiotapes of Sessions 1 and 4 by objective coders using the Alliance Observation Coding System. Autoregressive path analyses determined that first-session therapeutic alliance was a strong significant predictor of Session 4 depression symptoms, but pretreatment depression scores were not significantly predictive of subsequent therapeutic alliance. Adding reciprocal effects between alliance and depression scores did not adversely affect model fit, suggesting that reciprocal effects may exist. Early therapeutic alliance with adolescents is critical to fostering early gains in depressive symptomatology. Knowing alliance's subsequent effect on youth outcomes, clinicians should increase effort to foster a strong relationship in early sessions and additional research should be conducted on the reciprocal effects of therapeutic alliance and treatment outcome in adolescence.

    Many fisherman divers in Vietnam suffer from decompression sickness (DCS) causing joint pain, severe neurological deficit or even death. The objective of this pilot study was to evaluate the effectiveness of a training programme to prevent DCS and also treat DCS using the method of in-water recompression (IWR). 63 divers were interviewed and trained over a period of 3 years from 2009. Fifty one per cent of all trained divers were reinterviewed in 2011-2012 to collect mortality and morbidity data as well as information on changes in diving practices. Since 2009, most fisherman divers have changed their practices by reducing bottom time or depth. Mortality was reduced and the incidence of severe neurological DCS decreased by 75%. Twenty four cases of DCS were treated by IWR. Ten cases of joint pain were treated with IWR using air, affording immediate relief in all cases. Out of 10 cases of neurological DCS, 4/4 recovered completely after IWR with oxygen whereas only 2/6 subjects recovered immediately after IWR with air. In addition, 3/4 further cases of DCS treated with IWR using oxygen immediately recovered. Our results suggest that IWR is effective for severe neurological DCS in remote fishing communities, especially with oxygen. Published by the BMJ Publishing Group Limited.

    PubMed

    Horvath, Adam O

    2017-09-13

    The aim of this review paper is to summarize the challenges facing research on the alliance now and going forward. The review begins with a brief overview of the development of the concept of the alliance in historical context. A summary of what has been accomplished both within the psychotherapy research community and in other professions is presented. Current challenges facing this line of research are identified, including the existence of a wide range of operational definitions that results in a diffusion of the identity of the alliance concept. It is argued that the current situation generates risks to incremental growth in several lines of research. A case is made that a lack of clarity regarding how several variables within the broader category of therapeutic relationships fit together, overlap, or complement each other is also potentially problematic. Efforts to resolve the lack of a consensual definition are reviewed, and in conclusion, it is argued that a resumption of a conversation about the relationship in the helping context in general, and the alliance in particular, should be resumed.

  8. Alliance between tobacco and alcohol industries to shape public policy

    Jiang, Nan

    2013-01-01

    Aims The tobacco and alcohol industries share common policy goals when facing regulation, opposing policies such as tax increases and advertising restrictions. The collaboration between these two industries in the tobacco policy arena is unknown. This study explored if tobacco and alcohol companies built alliances to influence tobacco legislation, and if so, how those alliances worked. Methods Analysis of previously secret tobacco industry documents. Findings In the early 1980s, tobacco companies started efforts to build coalitions with alcohol and other industries to oppose cigarette excise taxes, clean indoor air policies, and tobacco advertising and promotion constraints. Alcohol companies were often identified as a key partner and source of financial support for the coalitions. These coalitions had variable success interfering with tobacco control policymaking. Conclusions The combined resources of tobacco and alcohol companies may have affected tobacco control legislation. These alliances helped to create the perception that there is a broader base of opposition to tobacco control. Advocates should be aware of the covert alliances between tobacco, alcohol, and other industries and expose them to correct this misperception. PMID:23587076

    Providing compassionate bereavement care for families experiencing perinatal loss is a standard of care in most healthcare organizations. In this article, we describe the development of The Alliance of Perinatal Bereavement Support Facilitators, begun over 25 years ago in Chicago by staff who identified the need to reach out to colleagues at other area institutions for advice and support in this work. This collaboration created a regional support network that has resulted in a long-lasting, active, sustainable organization of excellence focused on enhancing practice, education, and perinatal bereavement care. Alliance activities center around four main areas: education, networking/support, policy, and recognizing outstanding service to families. By continuing to draw upon the collective talent, wisdom, and expertise of its members, The Alliance still serves grieving families and provides mentoring for future interdisciplinary team members engaged in this work. The path taken to build this organization can be used by professionals in other specialties who are looking to create their own alliance infrastructure based on mutual benefit and interest.

  17. Dynamics of Alliance Formation and the Egalitarian Revolution

    PubMed Central

    2008-01-01

    Background Arguably the most influential force in human history is the formation of social coalitions and alliances (i.e., long-lasting coalitions) and their impact on individual power. Understanding the dynamics of alliance formation and its consequences for biological, social, and cultural evolution is a formidable theoretical challenge. In most great ape species, coalitions occur at individual and group levels and among both kin and non-kin. Nonetheless, ape societies remain essentially hierarchical, and coalitions rarely weaken social inequality. In contrast, human hunter-gatherers show a remarkable tendency to egalitarianism, and human coalitions and alliances occur not only among individuals and groups, but also among groups of groups. These observations suggest that the evolutionary dynamics of human coalitions can only be understood in the context of social networks and cognitive evolution. Methodology/Principal Findings Here, we develop a stochastic model describing the emergence of networks of allies resulting from within-group competition for status or mates between individuals utilizing dyadic information. The model shows that alliances often emerge in a phase transition-like fashion if the group size, awareness, aggressiveness, and persuasiveness of individuals are large and the decay rate of individual affinities is small. With cultural inheritance of social networks, a single leveling alliance including all group members can emerge in several generations. Conclusions/Significance We propose a simple and flexible theoretical approach for studying the dynamics of alliance emergence applicable where game-theoretic methods are not practical. Our approach is both scalable and expandable. It is scalable in that it can be generalized to larger groups, or groups of groups. It is expandable in that it allows for inclusion of additional factors such as behavioral, genetic, social, and cultural features. Our results suggest that a rapid transition from a

    2014-04-01

    The excitation intervention of strategic alliance may change with the changes in the parameters of circumstance (e.g., external alliance tasks). As a result, the stable cooperation between members may suffer a complete unplanned betrayal at last. However, current perspectives on strategic alliances cannot adequately explain this transition mechanism. This study is a first attempt to analyze this nonlinear phenomenon through stochastic catastrophe theory (SCT). A stochastic dynamics model is constructed based on the cooperation of strategic alliance from the perspective of evolutionary game theory. SCT explains the discontinuous changes caused by the changes in environmental parameters. Theoretically, we identify conditions where catastrophe can occur in the cooperation of alliance members.

    2016-11-01

    The capabilities of a single camera, volumetric velocimetry system for in situ measurement in marine environments are demonstrated by imaging a well-characterized flow in a laboratory environment. This work represents the first stages in the design of a SCUBA-diver operated system to study organisms and biological processes under the natural light in the water column. This system is primarily composed of a volumetric particle tracking diagnostic to investigate fluid-animal interactions. A target domain size of a 20 cm sided cube is sought as a key design feature for the capability of capturing the flow around a variety of benthic and freely swimming organisms. The integration of the particle tracking system with additional diagnostics will be discussed.

  1. Preconditioning methods and mechanisms for preventing the risk of decompression sickness in scuba divers: a review.

    PubMed

    Gempp, Emmanuel; Blatteau, Jean-Eric

    2010-07-01

    Scuba divers are at risk of decompression sickness due to the excessive formation of gas bubbles in blood and tissues following ascent, with potentially subsequent neurological injuries. Since nonprovocative dive profiles are no guarantor of protection against this disease, novel means are required for its prevention including predive procedures that could induce more resistance to decompression stress. In this article, we review the recent studies describing the promising preconditioning methods that might operate on the attenuation of bubble formation believed to reduce the occurrence of decompression sickness. The main practical applications are simple and feasible predive measures such as endurance exercise in a warm environment, oral hydration, and normobaric oxygen breathing. Rheological changes affecting tissue perfusion, endothelial adaptation with nitric oxide pathway, up-regulation of cytoprotective proteins, and reduction of preexisting gas nuclei from which bubbles grow could be involved in this protective effect.

    The mechanism of cerebral decompression sickness (DCS) is still unclear. We report 2 cases of breath-hold divers with cerebral DCS in whom magnetic resonance imaging (MRI) demonstrated distinctive characteristics. One case presented right hemiparesthesia, diplopia, and gait disturbance after breath-hold diving into the sea at a depth of 20 m. Brain MRI with fluid-attenuated inversion recovery (FLAIR) sequence revealed multiple hyperintense lesions in the right frontal lobe, bilateral thalamus, pons, and right cerebellar hemisphere. The second case presented visual and gait disturbance after repetitive breath-hold diving into the sea. FLAIR imaging showed hyperintense areas in the bilateral occipito-parietal lobes. In both cases, diffusion-weighted imaging and apparent diffusion coefficient mapping revealed hyperintense areas in the lesions identified by FLAIR. Moreover, follow-up MRI showed attenuation of the FLAIR signal abnormalities. These findings are suggestive of transient hyperpermeability in the microvasculature as a possible cause of cerebral DCS.

    Infective endocarditis is a diagnostic and therapeutic challenge that ultimately requires surgical intervention in 20% of all cases. Surgical treatment of active infective endocarditis requires not only hemodynamic repair, but also special emphasis on the eradiation of the infectious focus to prevent recurrence. This goal can be achieved by the combination of aggressive debridement of infective tissue and appropriate and adequate antibiotic treatment. We report a case of Streptococcus viridans induced aortic valve perforation related to aortic valve and root endocarditis, which was successfully treated with aortic root replacement using stentless bioprosthesis. This bioprosthesis thus seems to be a valuable option for active endocarditis, provides excellent hemodynamics with low gradients. Acceptable operative risk can be achieved by full root stentless valve replacement in physically active patients such as divers.

    Monitoring temperature of aquatic waters is of great importance, with modelled, satellite and in-situ data providing invaluable insights into long-term environmental change. However, there is often a lack of depth-resolved temperature measurements. Recreational dive computers routinely record temperature and depth, so could provide an alternate and highly novel source of oceanographic information to fill this data gap. In this study, a citizen science approach was used to obtain over 7,000 scuba diver temperature profiles. The accuracy, offset and lag of temperature records was assessed by comparing dive computers with scientific conductivity-temperature-depth instruments and existing surface temperature data. Our results show that, with processing, dive computers can provide a useful and novel tool with which to augment existing monitoring systems all over the globe, but especially in under-sampled or highly changeable coastal environments.

    Abstract Background: A number of occupations and professions may be associated with unique hazards relevant to urologic care. Case Presentation: We relate the presentation, care, and the occupational hazard of urinary tract infection (UTI), presenting as cystitis and pyelonephritis, with stone formation in a scuba diver. The patient voiced concern that his diving suit malfunction was related to his UTI and stone disease. We review the risk of UTI in the diving environment. We also report the development of infection-related stone in this case. Our evaluation included consultation with an expert in diving and associated equipment. Conclusion: Careful installation of P-valves in dry suits, proper maintenance, and monitoring for leakage improved post-dive hygiene, and proper maintenance of P-valve tubing and diving equipment may decrease the incidence of these complications described. Urologists treating UTI and stone disease should be aware of this occupation-related hazard. PMID:28164160

    2009-11-01

    Knowledge regarding arterial blood pressure (ABP) values during breath-hold diving is scanty. It derives from a few reports of measurements performed at the water's surface, showing slight or no increase in ABP, and from a single study of two simulated deep breath-hold dives in a hyperbaric chamber. Simulated dives showed an increase in ABP to values considered life threatening by standard clinical criteria. For the first time, using a novel noninvasive subaquatic sphygmomanometer, we successfully measured ABP in 10 healthy elite breath-hold divers at a depth of 10 m of freshwater (mfw). ABP was measured in dry conditions, at the surface (head-out immersion), and twice at a depth of 10 mfw. Underwater measurements of ABP were obtained in all subjects. Each measurement lasted 50-60 s and was accomplished without any complications or diver discomfort. In the 10 subjects as a whole, mean ABP values were 124/93 mmHg at the surface and 123/94 mmHg at a depth of 10 mfw. No significant statistical differences were found when blood pressure measurements at the water surface were compared with breath-hold diving conditions at a depth of 10 mfw. No systolic blood pressure values >140 mmHg or diastolic blood pressure values >115 mmHg were recorded. In conclusion, direct measurements of ABP during apnea diving showed no or only mild increases in ABP. However, our results cannot be extended over environmental conditions different from those of the present study.

    2016-08-01

    Inner ear decompression sickness (IEDCS) in scuba diving results in residual vestibulocochlear deficits with a potential impact on health-related quality of life. The aim of this study was to determine the predictive factors for poor clinical recovery and to try to establish a prognostic score on initial physical examination. The medical records of injured divers with IEDCS treated in our facility between 2009 and 2014 were retrospectively analyzed. The clinical severity of the deficit was evaluated on admission using a numerical scoring system taking into account the intensity of vestibular symptoms and the presence of cochlear signs. The clinical outcome was assessed at 3 mo by telephone interview. After multivariate analysis of potential risk factors for sequelae, the discriminating value of the score and these prognostic reliability indices were calculated. Among the 99 patients included in the study, 24% still had residual symptoms. Statistical analysis revealed that only a high clinical score [OR = 1.39 (95% CI 1.13-1.71)] and a delay in hyperbaric recompression >6 h [OR = 1.001 (95% CI 1-1.003)] were independently associated with incomplete recovery. The advantage of the score lay in its highly specific nature (92%) rather than its sensitivity (48%) for a threshold of 10. Results suggest that the severity of IEDCS can be easily determined by a clinical score during the acute phase. Recompression treatment should not be delayed.

    Inner ear decompression sickness (IEDCS) in scuba divers is increasingly observed, but epidemiological data are limited to small case series and the pathogenesis remains elusive. We report our experience over a 13-year period. We also thought to demonstrate that the development of this injury is mainly attributed to a mechanism of vascular origin. Diving information, clinical data, presence of circulatory right-to-left shunt (RLS), and laboratory investigations of 115 recreational divers were retrospectively analyzed. A follow-up study at 3 months was possible with the last 50 consecutive cases. IEDCS (99 males, 44 ± 11 years) represented 24 % of all the patients treated. The median delay of onset of symptoms after surfacing was 20 min. Violation of decompression procedure was recorded in 3 % while repetitive dives were observed in 33 %. The median time to hyperbaric treatment was 180 min. Pure vestibular disorders were observed in 76.5 %, cochlear deficit in 6 % and combination of symptoms in 17.5 %. Additional skin and neurological disorders were reported in 15 % of cases. In 77 %, a large RLS was detected with a preponderant right-sided lateralization of IEDCS (80 %, P < 0.001). Incomplete recovery was found in 68 % of the followed patients. Time to recompression did not seem to influence the clinical outcome. IEDCS is a common presentation of decompression sickness following an uneventful scuba dive, but the therapeutic response remains poor. The high prevalence of RLS combined with a right-sided predominance of inner ear dysfunction suggests a preferential mechanism of paradoxical arterial gas emboli through a vascular anatomical selectivity.

  12. Alveolar gas composition before and after maximal breath-holds in competitive divers.

    2006-01-01

    The urge to breathe, as stimulated by hypercapnia, is generally considered to cause a breath-hold diver to end the breath-hold, and pre-breath hold hyperventilation has been suggested to cause hypoxic loss of consciousness (LOC) due to the reduced urge to breathe. Competitors hyperventilate before "Static Apnea", yet only 10% surface with symptoms of hypoxia such as loss of motor control (LMC) or LOC. We hypothesized that the extensive hyperventilation would prevent hypercapnia even during prolonged breath-holding and we also recorded breaking-point end-tidal PO2 in humans. Nine breath-hold divers performed breath-holds of maximal duration according to their chosen "Static Apnea" procedure. They floated face down in a swimming pool (28 degrees C). The only non-standard procedure was that they exhaled into a sampling tube for end-expiratory air, before starting the breath-hold and before resuming breathing. Breath-hold duration was 284 +/- 25 (SD) seconds. End-tidal PCO2 was 18.9 +/- 2.0 mmHg before apnea and 38.3 +/- 4.7 mmHg at apnea termination. End-tidal PO2 was 131.7 +/- 2.7 mmHg before apnea and 26.9 +/- 7.5 mmHg at apnea termination. Two of the subjects showed LMC after exhaling into the sampling tube; their end-tidal PAO2 values were 19.6 and 21.0 mmHg, respectively. End-tidal CO2 was normocapnic or hypocapnic at the termination of breath-holds. These data suggest that the athletes rely primarily on the hypoxic stimuli, probably in interaction with CO2 stimuli to determine when to end breath-holds. The severity of hypoxia close to LOC was similar to that reported for acute hypobaric hypoxia in humans.

    Human thermal responses during prolonged whole-body immersion in cold water are of interest for the military, especially French SEALS. This study aims at describing the thermo-physiological responses. There were 10 male military divers who were randomly assigned to a full immersion in neutral (34 degrees C), moderately cold (18 degrees C), and cold (10 degrees C) water wearing their operational protective devices (5.5 mm wetsuit with 3.0 mm thick underwear) for 6 h in a static position. Rectal temperature (T(re)) and 14 skin temperatures (T(sk)), blood analysis (stress biomarkers, metabolic substrates), and oxygen consumption (Vo2) were collected. At 34 degrees C, there were no significant modifications of the thermo-physiological responses over time. The most interesting result was that rates of rectal temperature decrease (0.15 +/- 0.02 degrees C x min(-1)) were the same between the two cold stress experimental conditions (at 18 degrees C and 10 degrees C). At the final experiment, rectal temperature was not significantly different between the two cold stress experimental conditions. Mean T(sk) decreased significantly during the first 3 h of immersion and then stabilized at a lower level at 10 degrees C (25.6 +/- 0.8 degrees C) than at 18 degrees C (29.3 +/- 0.9 degrees C). Other results demonstrate that the well-trained subjects developed effective physiological reactions. However, these reactions are consistently too low to counterbalance the heat losses induced by cold temperature conditions and long-duration immersion. This study shows that providing divers with thermal protection is efficient for a long-duration immersion from a medical point of view, but not from an operational one when skin extremities were taken into account.

    We previously showed microvascular alteration of both endothelium-dependent and -independent reactivity after a single SCUBA dive. We aimed to study mechanisms involved in this postdive vascular dysfunction. Ten divers each completed three protocols: (1) a SCUBA dive at 400 kPa for 30 min; (2) a 41-min duration of seawater surface head immersed finning exercise to determine the effect of immersion and moderate physical activity; and (3) a simulated 41-min dive breathing 100% oxygen (hyperbaric oxygen [HBO]) at 170 kPa in order to analyze the effect of diving-induced hyperoxia. Bubble grades were monitored with Doppler. Cutaneous microvascular function was assessed by laser Doppler. Endothelium-dependent (acetylcholine, ACh) and -independent (sodium nitroprusside, SNP) reactivity was tested by iontophoresis. Endothelial cell activation was quantified by plasma Von Willebrand factor and nitric oxide (NO). Inactivation of NO by oxidative stress was assessed by plasma nitrotyrosine. Platelet factor 4 (PF4) was assessed in order to determine platelet aggregation. Blood was also analyzed for measurement of platelet count. Cutaneous vascular conductance (CVC) response to ACh delivery was not significantly decreased by the SCUBA protocol (23 ± 9% before vs. 17 ± 7% after; P = 0.122), whereas CVC response to SNP stimulation decreased significantly (23 ± 6% before vs. 10 ± 1% after; P = 0.039). The HBO and immersion protocols did not affect either endothelial-dependent or -independent function. The immersion protocol induced a significant increase in NO (0.07 ± 0.01 vs. 0.12 ± 0.02 μg/mL; P = 0.035). This study highlighted change in microvascular endothelial-independent but not -dependent function in highly trained divers after a single air dive. The results suggest that the effects of decompression on microvascular function may be modified by diving acclimatization. PMID:24400144

    Most of the literature on the alliance-outcome association is based exclusively on differences between patient reports on alliance. Much less is known about the unique contribution of the therapist's report to this association across treatment, that is, the association between therapist-reported alliance and outcome over the course of treatment, after controlling for the patient's contribution. The present study is the first to examine the unique contribution of the therapist-reported alliance to outcome, accounting for reverse causation (symptomatic levels predicting alliance), at several time points in the course of treatment. Of 156 patients randomized to dynamic supportive-expressive psychotherapy, antidepressant medication with clinical management, and placebo with clinical management, 149 were included in the present study. Alliance was assessed from the perspective of both the patient and the therapist. Outcome measures included the patients' self-reported and diagnostician-rated depressive symptoms. Overall, the findings demonstrate that the therapists' contribution to the alliance-outcome association was explained mainly by prior symptomatic levels. However, when a time lag of several sessions was introduced between alliance and symptoms, a positive association emerged between alliance at 1 time point and symptomatic distress assessed several sessions later in the treatment, controlling for previous symptomatic level. The findings were similar whether or not we controlled for the patient's perspective on the alliance. Taken together, the findings attest to the importance of improving therapists' ability to detect deterioration in the alliance.

    The impact of early therapeutic alliance was examined in 100 clients receiving either individual cognitive– behavioral therapy (CBT) or family therapy for adolescent substance abuse. Observational ratings of adolescent alliance in CBT and adolescent and parent alliance in family therapy were used to predict treatment retention (in CBT only) and outcome (drug use, externalizing, and internalizing symptoms in both conditions) at post and 6-month follow-up. There were no alliance effects in CBT. In family therapy, stronger parent alliance predicted declines in drug use and externalizing. Adolescents with weak early alliances that subsequently improved by midtreatment showed significantly greater reductions in externalizing than adolescents whose alliances declined. Results underscore the need for ongoing developmental calibration of intervention theory and practice for adolescent clinical populations. PMID:16551149

    The objective of this study was to investigate the role of therapeutic alliance on suicide ideation as outcome measure in a brief therapy for patients who attempted suicide. Sixty patients received the 3-session therapy supplemented by follow-up contact through regular letters. Therapeutic alliance was measured with the Helping Alliance Questionnaire (HAQ). Outcome at 6 and 12 months was measured with the Beck Scale for Suicide Ideation (BSS). Therapeutic alliance increased from session 1 to session 3. Higher alliance measures correlated with lower suicidal ideation at 12 months follow-up. A history of previous attempts and depression had a negative affect on therapeutic alliance. The results suggest that in the treatment of suicidal patients therapeutic alliance may be a moderating factor for reducing suicide ideation.

    Much research has been carried out to evaluate the impact of strategic alliance membership on the performance of airlines. However it would be of interest to identify how airlines perceive this impact in terms of branding by each of the three global alliance groupings. It is the purpose of this paper to gather the opinion of airlines, belonging to the three strategic alliance groups, on the impact that the strategic alliance brands have had on their individual brands and how do they perceive that this impact will change in the future. To achieve this, a comprehensive survey of the alliance management and marketing departments of airlines participating in the three global strategic alliances was required. The results from this survey give an indication whether the strategic airline alliances, which are often referred to as marketing agreements, enhance, damage or have no impact on the individual airline brands.

    This study examined predictive relations between therapeutic alliance and treatment outcomes in manual-guided, cognitive-behavioral therapy for adolescent depression. Fifty-four adolescents met criteria for a depressive disorder and were treated in school-based clinics. Alliance was measured after the third session from both therapist and adolescent perspectives, and change in depressive symptoms was assessed by structured interview and self-report. Two models of alliance-outcome relations were assessed, one direct and one through treatment participation. Results showed significant associations between adolescent-reported alliance and change in depressive symptoms, even after controlling for number of sessions completed. Therapist-reported alliance was only marginally related to outcomes but was predictive of number of sessions completed. On average, alliance showed a modest relation with outcomes (r = .26). Results are discussed in the context of differential alliance-outcome relations in prior studies of cognitive-behavioral compared to nonbehavioral therapy with children and adolescents.

    The therapeutic alliance consistently predicts positive psychotherapy outcomes. Thus, it is important to uncover factors that relate to alliance development. The goal of this study was to examine the association between patient interpersonal characteristics and alliance quality in interpersonal therapy for depression. Data derive from a subsample (n = 74) of a larger naturalistic database of outpatients treated at a mood disorders clinic of a university-affiliated psychiatric hospital. Following Session 3 of treatment, therapists completed the Impact Message Inventory (Kiesler & Schmidt, 1993) to assess patients' interpersonal impacts on them. Also following Session 3, patients completed the Working Alliance Inventory (Horvath & Greenberg, 1989) to assess alliance quality. As predicted, patients' affiliative interpersonal impacts, as perceived by their therapists, were positively associated with alliance quality, controlling for baseline depression severity. Although unrelated to the initial hypotheses, patients concurrently taking psychotropic medications reported better alliances than patients receiving psychotherapy only.

    Objective To examine the dependability of alliance scores at the patient and therapist level, to evaluate the potential causal direction of session-to-session changes in alliance and depressive symptoms, and to investigate the impact of aggregating the alliance over progressively more sessions on the size of the alliance-outcome relationship. Method We used data from a study (N=45 patients; N=9 therapists) of psychotherapy for major depressive disorder in which the alliance was measured at every treatment session to calculate generalizability coefficients and to predict change in depressive symptoms from alliance scores. Two replication samples were also used. Results At the therapist level, a large number of patients (about 60) per therapist is needed to provide a dependable therapist-level alliance score. At the patient level, generalizability coefficients revealed that a single assessment of the alliance is only marginally acceptable. Very good (> .90) dependability at the patient level is only achieved through aggregating four or more assessments of the alliance. Session-to-session change in the alliance predicted subsequent session-to-session changes in symptoms. Evidence for reverse causation was found in later-in-treatment sessions, suggesting that only aggregates of early treatment alliance scores should be used to predict outcome. Session 3 alliance scores explained 4.7% of outcome variance but the average of sessions 3 to 9 explaining 14.7% of outcome variance. Conclusion Adequately assessing the alliance using multiple patients per therapist and at least 4 treatment sessions is crucial to fully understanding the size of the alliance-outcome relationship.

    In activists' circles as in sociology, the concept "safe space" has been applied to all sorts of programs, organizations, and practices. Few studies have specified clearly what safe spaces are and how they support the people who occupy them. We examine one social location typically understood to be a safe space: gay-straight alliance groups in high schools. Using qualitative interviews with young adults in the United States and Canada who have participated in gay-straight alliances, we unpack this complex concept to consider some of the dimensions along which safe spaces might vary. Based on interviews with participants, we derive three interrelated dimensions of safe space: social context, membership, and activity.

    Detecting defection and alarming partners about the possible danger could be essential to avoid being exploited. This act, however, may require a huge individual effort from those who take this job, hence such a strategy seems to be unfavorable. But structured populations can provide an opportunity where a largely unselfish excluder strategy can form an effective alliance with other cooperative strategies, hence they can sweep out defection. Interestingly, this alliance is functioning even at the extremely high cost of exclusion where the sole application of an exclusion strategy would be harmful otherwise. These results may explain why the emergence of extreme selfless behavior is not necessarily against individual selection but could be the result of an evolutionary process.

    This analysis was conducted to describe the concept of therapeutic alliance and its appropriateness for health-care provider-client interactions during the childbearing season. The concept has been defined in other disciplines. A universal definition suggested a merging of efforts directed toward health. A simple and concise definition evolved, which is applicable to the childbearing season as well as to health-care encounters across the life span. This definition states: Therapeutic alliance is a process within a health-care provider-client interaction that is initiated by an identified need for positive client health-care behaviors, whereby both parties work together toward this goal with consideration of the client's current health status and developmental stage within the life span.

    This article discusses alliances within local socio-sanitary space, one in which community sector and health sector actors, public health researchers and funding bodies meet. The discussion is based on the study of a research space made up of representatives of actors found at the local level. Both the minutes of the discussions of 12 meetings of the research team, and the collaborative outputs produced throughout the research initiative provide the empirical data for a qualitative analysis. The findings reveal a research space concomitantly constituted by aspects of "non-cooperative games" and of networks based on innovation-fostering knowledge exchanges, which can be viewed, from the perspective of a reflexive epistemology, as a tool for implementing innovative alliances in local, health-promoting socio-sanitary space.

    The paper traces the evolution and working of the Global Equity Gauge Alliance (GEGA) and its efforts to promote health equity. GEGA places health equity squarely within a larger framework of social justice, linking findings on socioeconomic and health inequalities with differentials in power, wealth, and prestige in society. The Alliance's 11 country-level partners, called Equity Gauges, share a common action-based vision and framework called the Equity Gauge Strategy. An Equity Gauge seeks to reduce health inequities through three broad spheres of action, referred to as the 'pillars' of the Equity Gauge Strategy, which define a set of interconnected and overlapping actions. Measuring and tracking the inequalities and interpreting their ethical import are pursued through the Assessment and Monitoring pillar. This information provides an evidence base that can be used in strategic ways for influencing policy-makers through actions in the Advocacy pillar and for supporting grassroots groups and civil society through actions in the Community Empowerment pillar. The paper provides examples of strategies for promoting pro-equity policy and social change and reviews experiences and lessons, both in terms of technical success of interventions and in relation to the conceptual development and refinement of the Equity Gauge Strategy and overall direction of the Alliance. To become most effective in furthering health equity at both national and global levels, the Alliance must now reach out to and involve a wider range of organizations, groups, and actors at both national and international levels. Sustainability of this promising experiment depends, in part, on adequate resources but also on the ability to attract and develop talented leadership.

  20. ALLIANCE: An architecture for fault tolerant multi-robot cooperation

    SciTech Connect

    Parker, L.E.

    1995-02-01

    ALLIANCE is a software architecture that facilitates the fault tolerant cooperative control of teams of heterogeneous mobile robots performing missions composed of loosely coupled, largely independent subtasks. ALLIANCE allows teams of robots, each of which possesses a variety of high-level functions that it can perform during a mission, to individually select appropriate actions throughout the mission based on the requirements of the mission, the activities of other robots, the current environmental conditions, and the robot`s own internal states. ALLIANCE is a fully distributed, behavior-based architecture that incorporates the use of mathematically modeled motivations (such as impatience and acquiescence) within each robot to achieve adaptive action selection. Since cooperative robotic teams usually work in dynamic and unpredictable environments, this software architecture allows the robot team members to respond robustly, reliably, flexibly, and coherently to unexpected environmental changes and modifications in the robot team that may occur due to mechanical failure, the learning of new skills, or the addition or removal of robots from the team by human intervention. The feasibility of this architecture is demonstrated in an implementation on a team of mobile robots performing a laboratory version of hazardous waste cleanup.
