    First aid measures can be life-saving. Starting first aid education early may strengthen interest, motivation and ability to provide first aid. To determine if a first aid teaching program including 5 lessons (45 min each) of theoretical and practical training for 6-7-year-old children can influence their performance in a first aid scenario. 228 primary school children at the age of 6-7 years were included in the study, 102 girls and 126 boys. One child was 5 years old. 117 children were taught basic first aid measures and 111 without training served as control group. In the test scenario the children had to provide first aid to an unconscious victim after a cycle accident. The course participants were retested after 6 months. Statistically significant differences between course participants compared to those without training could be shown for all tested subjects, including correct assessment of consciousness (p<0.001), correct assessment of breathing (p<0.001), knowledge of the correct emergency telephone number (p<0.001), giving correct emergency call information (p<0.001), knowledge of correct recovery position (p<0.001), correct airway management (p<0.001). Retesting after 6 months showed statistically significant differences for 5 of 6 tested items. 6-7-Year-old children can give basic first aid to an unconscious patient. A course with 5 lessons leads to a significant increase in first aid knowledge and skills. Knowledge retention is good after 6 months. All primary school children should receive first aid training starting in first grade.

    Underwater inherent optical properties (IOPs) are the fundamental clues to many research fields such as marine optics, marine biology, and underwater vision. Currently, beam transmissometers and optical sensors are considered as the ideal IOPs measuring methods. But these methods are inflexible and expensive to be deployed. To overcome this problem, we aim to develop a novel measuring method using only a single underwater image with the help of deep artificial neural network. The power of artificial neural network has been proved in image processing and computer vision fields with deep learning technology. However, image-based IOPs estimation is a quite different and challenging task. Unlike the traditional applications such as image classification or localization, IOP estimation looks at the transparency of the water between the camera and the target objects to estimate multiple optical properties simultaneously. In this paper, we propose a novel Depth Aided (DA) deep neural network structure for IOPs estimation based on a single RGB image that is even noisy. The imaging depth information is considered as an aided input to help our model make better decision.

    This study evaluated the risk of failure for an endodontically treated premolar with different crack depths, which was shearing toward the pulp chamber and was restored by using 3 different computer-aided design/computer-aided manufacturing ceramic restoration configurations. Three 3-dimensional finite element models designed with computer-aided design/computer-aided manufacturing ceramic onlay, endocrown, and conventional crown restorations were constructed to perform simulations. The Weibull function was incorporated with finite element analysis to calculate the long-term failure probability relative to different load conditions. The results indicated that the stress values on the enamel, dentin, and luting cement for endocrown restorations exhibited the lowest values relative to the other 2 restoration methods. Weibull analysis revealed that the overall failure probabilities in a shallow cracked premolar were 27%, 2%, and 1% for the onlay, endocrown, and conventional crown restorations, respectively, in the normal occlusal condition. The corresponding values were 70%, 10%, and 2% for the depth cracked premolar. This numeric investigation suggests that the endocrown provides sufficient fracture resistance only in a shallow cracked premolar with endodontic treatment. The conventional crown treatment can immobilize the premolar for different cracked depths with lower failure risk. Copyright © 2013 American Association of Endodontists. Published by Elsevier Inc.

    Posterior epistaxis is a serious condition that can be difficult to treat in a wilderness setting. The initial standard of care involves packing the affected nostril with a 7 to 9 cm nasal pack to tamponade the bleed. These packs are often unavailable outside of the emergency or operating room. This study set out to determine whether a posterior nasal pack could be constructed from the supplies present in a basic first aid kit in order to control massive nasal hemorrhage in a wilderness setting. A basic first aid kit was utilized to construct a posterior nasal pack that was inserted into an anatomical model and visibly compared with the Rapid Rhino (Posterior, 7.5 cm; Smith & Nephew, Austin, TX) nasal packing. The shape, size, and anatomical areas of compression (ie, into nasopharynx and posterior aspect of inferior turbinate) of this pack was similar to the commercially available posterior nasal pack. Placement in an anatomical model appears to provide similar compression as the commercially available posterior pack. This technique may provide short-term hemorrhage control in cases of serious posterior nasal hemorrhage where standard treatment options are not available.

    Annually, more than 127,000 people are killed and at least 2.4 million people injured in road accidents in Europe. Consequently, in half of all countries in the European Union a first aid and basic life support course has become mandatory for learner drivers. The aim of this study was to evaluate the effect of this course on participants' knowledge and self-assessed first aid and basic life support skills. Participants were given a questionnaire before and after course. In total, 115 participants (response rate 98%) were included in the study. Mean age was 20 years (46% female and 54% male). Out of 12 questions, the average number of correct answers increased from 5.6 before the course to 8.7 after the course (p < 0.001). Upon completion of the course, 95% or more of the participants knew how to prioritise treatment of several casualties, knew how to relieve a foreign body airway obstruction, and knew the recommended compression-ventilation ratio during CPR (p < 0.001 for all). Despite significant improvements after the course only 64% knew how to diagnose cardiac arrest, 44% knew when to activate an automatic external defibrillator and 23% were aware of when to activate the emergency medical services. Participants significantly increased their self-confidence in own skills after the course (p < 0.001). A mandatory course for learner drivers significantly improves participants' knowledge and their self-assessed skills in first aid and basic life support. However, improvements of the course should be considered on a number of key topics. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    The aim of this study was to evaluate the levels of knowledge of pre-school teachers working in the province center of Isparta related with basic first-aid practices and some factors which affected these levels of knowledge. In this cross-sectional, analytic study, 110 pre-school teachers working in the province center of Isparta constituted the population. A questionnaire questioning sociodemographic properties and the level of knowledge related with first-aid practices was applied under supervision. The level of knowledge was evaluated on a 20-point scale. In the analyses, Kruskal-Wallis and Mann-Whitney U tests and Spearman's rank correlation were used. The study was approved by the Ethical Committee for Clinical Studies of Süleyman Demirel University School of Medicine (registration number: 105). The mean score of first-aid knowledge of the pre-school teachers was found to be 11.9±2.9. The least known issues included washing the wound by soap and water after a dog bite, information related with the necessity of immobilization of a child who has fallen from a high level and the phone number of National Poison Information Center (16.4%, 20.9% and 22.7%, respectively). The scores of the subjects whose knowledge of first-aid was evaluated to be well were higher compared to the subjects whose knowledge of first-aid was evaluated to be moderate (p=0.009) and poor (p=0.001). It was found that first-aid scores did not show significant difference in terms of age, working period, having received first-aid training and having faced with a condition requiring first-aid previously (p>0.05, for all comparisons). It was found that pre-school teachers had insufficient first-aid knowledge. Since the first-aid knowledge scores of the subjects who reported that they received first-aid training before did not show significant difference, it was thought that the quality of training was as important as receiving training.

    The challenges presented by traumatic injuries in low-resource communities are especially relevant in South Sudan. This study was conducted to assess whether a 3-day wilderness first aid (WFA) training course taught in South Sudan improved first aid knowledge. Stonehearth Open Learning Opportunities (SOLO) Schools designed the course to teach people with limited medical knowledge to use materials from their environment to provide life-saving care in the event of an emergency. A pre-test/post-test study design was used to assess first aid knowledge of 46 community members in Kit, South Sudan, according to a protocol approved by the University of New England Institutional Review Board. The course and assessments were administered in English and translated in real-time to Acholi and Arabic, the two primary languages spoken in the Kit region. Descriptive statistics, t-test, ANOVA, and correlation analyses were conducted. Results included a statistically significant improvement in first aid knowledge after the 3-day training course: t(38)=3.94; P<.001. Although men started with more health care knowledge: (t(37)=2.79; P=.008), men and women demonstrated equal levels of knowledge upon course completion: t(37)=1.56; P=.88. This research, which may be the first of its kind in South Sudan, provides evidence that a WFA training course in South Sudan is efficacious. These findings suggest that similar training opportunities could be used in other parts of the world to improve basic medical knowledge in communities with limited access to medical resources and varying levels of education and professional experiences.

    Early signs interventions show promise but could be further developed. A recent review suggested that 'basic symptoms' should be added to conventional early signs to improve relapse prediction. This study builds on preliminary evidence that basic symptoms predict relapse and aimed to: 1. examine which phenomena participants report prior to relapse and how they describe them; 2. determine the best way of identifying pre-relapse basic symptoms; 3. assess current practice by comparing self- and casenote-reported pre-relapse experiences. Participants with non-affective psychosis were recruited from UK mental health services. In-depth interviews (n=23), verbal checklists of basic symptoms (n=23) and casenote extracts (n=208) were analysed using directed content analysis and non-parametric statistical tests. Three-quarters of interviewees reported basic symptoms and all reported conventional early signs and 'other' pre-relapse experiences. Interviewees provided rich descriptions of basic symptoms. Verbal checklist interviews asking specifically about basic symptoms identified these experiences more readily than open questions during in-depth interviews. Only 5% of casenotes recorded basic symptoms; interviewees were 16 times more likely to report basic symptoms than their casenotes did. The majority of interviewees self-reported pre-relapse basic symptoms when asked specifically about these experiences but very few casenotes reported these symptoms. Basic symptoms may be potent predictors of relapse that clinicians miss. A self-report measure would aid monitoring of basic symptoms in routine clinical practice and would facilitate a prospective investigation comparing basic symptoms and conventional early signs as predictors of relapse.

    Independent navigation for blind individuals can be extremely difficult due to the inability to recognise and avoid obstacles. Assistive techniques such as white canes, guide dogs, and sensory substitution provide a degree of situational awareness by relying on touch or hearing but as yet there are no techniques that attempt to make use of any residual vision that the individual is likely to retain. Residual vision can restricted to the awareness of the orientation of a light source, and hence any information presented on a wearable display would have to limited and unambiguous. For improved situational awareness, i.e. for the detection of obstacles, displaying the size and position of nearby objects, rather than including finer surface details may be sufficient. To test whether a depth-based display could be used to navigate a small obstacle course, we built a real-time head-mounted display with a depth camera and software to detect the distance to nearby objects. Distance was represented as brightness on a low-resolution display positioned close to the eyes without the benefit focussing optics. A set of sighted participants were monitored as they learned to use this display to navigate the course. All were able to do so, and time and velocity rapidly improved with practise with no increase in the number of collisions. In a second experiment a cohort of severely sight-impaired individuals of varying aetiologies performed a search task using a similar low-resolution head-mounted display. The majority of participants were able to use the display to respond to objects in their central and peripheral fields at a similar rate to sighted controls. We conclude that the skill to use a depth-based display for obstacle avoidance can be rapidly acquired and the simplified nature of the display may appropriate for the development of an aid for sight-impaired individuals.

    Depth filtration is widely used in downstream bioprocessing to remove particulate contaminants via depth straining and is therefore applied to harvest clarification and other processing steps. However, depth filtration also removes proteins via adsorption, which can contribute variously to impurity clearance and to reduction in product yield. The adsorption may occur on the different components of the depth filter, that is, filter aid, binder, and cellulose filter. We measured adsorption of several model proteins and therapeutic proteins onto filter aids, cellulose, and commercial depth filters at pH 5-8 and ionic strengths <50 mM and correlated the adsorption data to bulk measured properties such as surface area, morphology, surface charge density, and composition. We also explored the role of each depth filter component in the adsorption of proteins with different net charges, using confocal microscopy. Our findings show that a complete depth filter's maximum adsorptive capacity for proteins can be estimated by its protein monolayer coverage values, which are of order mg/m 2 , depending on the protein size. Furthermore, the extent of adsorption of different proteins appears to depend on the nature of the resin binder and its extent of coating over the depth filter surface, particularly in masking the cation-exchanger-like capacity of the siliceous filter aids. In addition to guiding improved depth filter selection, the findings can be leveraged in inspiring a more intentional selection of components and design of depth filter construction for particular impurity removal targets. © 2018 Wiley Periodicals, Inc.

    . Over the past decade, the New York State dairy industry has grown substantially, resulting in an increase in immigrant workers who speak languages other than English. Estimates suggest that over 50% of workers on large New York dairies are Spanish-speaking individuals who immigrated to the U.S. from Guatemala, Mexico, and other Latin American countries. With a growing population of Spanish-speaking workers, safety concerns on farms have become a prominent issue. This article reviews the development and evaluation of a basic dairy first aid curriculum, which is intended to educate Spanish-speaking immigrant dairy workers on emergency response and first aid. The materials developed are culturally relevant and can be easily understood by low-literacy, non-English-speaking workers. In evaluation of the materials using pre- and post-testing, a significant knowledge gain was identified in workers who participated in the training.

    Compared to basic-feature hearing aids, premium-feature hearing aids have more advanced technologies and sophisticated features. The objective of this study was to explore the difference between premium-feature and basic-feature hearing aids in horizontal sound localization in both laboratory and daily life environments. We hypothesized that premium-feature hearing aids would yield better localization performance than basic-feature hearing aids. Exemplars of premium-feature and basic-feature hearing aids from two major manufacturers were evaluated. Forty-five older adults (mean age 70.3 years) with essentially symmetrical mild to moderate sensorineural hearing loss were bilaterally fitted with each of the four pairs of hearing aids. Each pair of hearing aids was worn during a 4-week field trial and then evaluated using laboratory localization tests and a standardized questionnaire. Laboratory localization tests were conducted in a sound-treated room with a 360°, 24-loudspeaker array. Test stimuli were high frequency and low frequency filtered short sentences. The localization test in quiet was designed to assess the accuracy of front/back localization, while the localization test in noise was designed to assess the accuracy of locating sound sources throughout a 360° azimuth in the horizontal plane. Laboratory data showed that unaided localization was not significantly different from aided localization when all hearing aids were combined. Questionnaire data showed that aided localization was significantly better than unaided localization in everyday situations. Regarding the difference between premium-feature and basic-feature hearing aids, laboratory data showed that, overall, the premium-feature hearing aids yielded more accurate localization than the basic-feature hearing aids when high-frequency stimuli were used, and the listening environment was quiet. Otherwise, the premium-feature and basic-feature hearing aids yielded essentially the same performance in

    Physiatrists have provided humanitarian assistance in recent large-scale global natural disasters. Super Typhoon Haiyan, the deadliest and most costly typhoon in modern Philippine history, made landfall on 8 November 2013 resulting in significant humanitarian needs. Philippine Academy of Rehabilitation Medicine physiatrists conducted a project of 23 emergency basic relief and medical aid missions in response to Super Typhoon Haiyan from November 2013 to February 2014. The final mission was a medical aid mission to the inland rural community of Burauen, Leyte. Summary data were collected, collated, and tabulated; project and mission evaluation was performed. During the humanitarian assistance project, 31,254 basic relief kits containing a variety of food and non-food items were distributed and medical services including consultation, treatment, and medicines were provided to 7255 patients. Of the 344 conditions evaluated in the medical aid mission to Burauen, Leyte 85 (59%) were physical and rehabilitation medicine conditions comprised of musculoskeletal (62 [73%]), neurological (17 [20%]), and dermatological (6 [7%]) diagnoses. Post-mission and project analysis resulted in recommendations and programmatic changes to strengthen response in future disasters. Physiatrists functioned as medical providers, mission team leaders, community advocates, and in other roles. This physiatrist-led humanitarian assistance project met critical basic relief and medical aid needs of persons impacted by Super Typhoon Haiyan, demonstrating significant roles performed by physiatrists in response to a large-scale natural disaster. Resulting disaster programing changes and recommendations may inform a more effective response by PARM mission teams in the Philippines as well as by other South-Eastern Asia teams comprising rehabilitation professionals to large-scale, regional natural disasters.

    2011-01-01

    Depth is the feeling of remoteness, or separateness, that accompanies awareness in human modalities like vision and audition. In specific cases depths can be graded on an ordinal scale, or even measured quantitatively on an interval scale. In the case of pictorial vision this is complicated by the fact that human observers often appear to apply mental transformations that involve depths in distinct visual directions. This implies that a comparison of empirically determined depths between observers involves pictorial space as an integral entity, whereas comparing pictorial depths as such is meaningless. We describe the formal structure of pictorial space purely in the phenomenological domain, without taking recourse to the theories of optics which properly apply to physical space-a distinct ontological domain. We introduce a number of general ways to design and implement methods of geodesy in pictorial space, and discuss some basic problems associated with such measurements. We deal mainly with conceptual issues.

  1. An efficient depth map preprocessing method based on structure-aided domain transform smoothing for 3D view generation

    Depth image-based rendering (DIBR), which is used to render virtual views with a color image and the corresponding depth map, is one of the key techniques in the 2D to 3D conversion process. Due to the absence of knowledge about the 3D structure of a scene and its corresponding texture, DIBR in the 2D to 3D conversion process, inevitably leads to holes in the resulting 3D image as a result of newly-exposed areas. In this paper, we proposed a structure-aided depth map preprocessing framework in the transformed domain, which is inspired by recently proposed domain transform for its low complexity and high efficiency. Firstly, our framework integrates hybrid constraints including scene structure, edge consistency and visual saliency information in the transformed domain to improve the performance of depth map preprocess in an implicit way. Then, adaptive smooth localization is cooperated and realized in the proposed framework to further reduce over-smoothness and enhance optimization in the non-hole regions. Different from the other similar methods, the proposed method can simultaneously achieve the effects of hole filling, edge correction and local smoothing for typical depth maps in a united framework. Thanks to these advantages, it can yield visually satisfactory results with less computational complexity for high quality 2D to 3D conversion. Numerical experimental results demonstrate the excellent performances of the proposed method. PMID:28407027

    Undergraduate medical students follow a compulsory first aid (FA) and basic life support (BLS) course. Retention of BLS seems poor and only little information is provided on the retention of FA skills. This study aims at evaluating 1- and 2-year retention of FA and BLS training in undergraduate medical students. One hundred and twenty students were randomly selected from first year (n=349) medical students who successfully followed a compulsory FA and BLS course. From these 120 students, 94 (78%) and 69 (58%) participated in retention tests of FA and BLS skills after 1 and 2 years, respectively. The assessment consisted of two FA stations and one BLS station. After 1 year, only 2% passed both FA and BLS stations and 68% failed both FA and BLS stations. After 2 years, 5% passed and 50% failed both FA and BLS stations. Despite the high failure rate at the stations, 90% adequately checked vital signs and started cardiopulmonary resuscitation appropriately. The long-term retention of FA and BLS skills after a compulsory course in the first year is poor. Adequate check of vital signs and commencing cardiopulmonary resuscitation retained longer.

    Does the addition of stereoscopic depth aid steering--the perceptual control of locomotor heading--around an environment? This is a critical question when designing a tele-operation or Virtual Environment system, with implications for computational resources and visual comfort. We examined the role of stereoscopic depth in the perceptual control of heading by employing an active steering task. Three conditions were tested: stereoscopic depth; incorrect stereoscopic depth and no stereoscopic depth. Results suggest that stereoscopic depth does not improve performance in a visual control task. A further set of experiments examined the importance of a ground plane. As a ground plane is a common feature of all natural environments and provides a pictorial depth cue, it has been suggested that the visual system may be especially attuned to exploit its presence. Thus it would be predicted that a ground plane would aid judgments of locomotor heading. Results suggest that the presence of rich motion information in the lower visual field produces significant performance advantages and that provision of such information may prove a better target for system resources than stereoscopic depth. These findings have practical consequences for a system designer and also challenge previous theoretical and psychophysical perceptual research.

  15. Impact of Hearing Aid Technology on Outcomes in Daily Life I: the Patients’ Perspective

    PubMed Central

    Cox, Robyn M; Johnson, Jani A; Xu, Jingjing

    2016-01-01

    Objectives One of the challenges facing hearing care providers when recommending hearing aids is the choice of device technology level. Major manufacturers market families of hearing aids that are described as spanning the range from basic technology to premium technology. Premium technology hearing aids include acoustical processing capabilities (features) that are not found in basic technology instruments. These premium features are intended to yield improved hearing in daily life compared to basic-feature devices. However, independent research that establishes the incremental effectiveness of premium-feature devices compared to basic-feature devices is lacking. This research was designed to explore reported differences in hearing abilities for adults using premium-feature and basic-feature hearing aids in their daily lives. Design This was a single-blinded, repeated, crossover trial in which the participants were blinded. All procedures were carefully controlled to limit researcher bias. Forty-five participants used carefully fitted bilateral hearing aids for one month and then provided data to describe the hearing improvements or deficiencies noted in daily life. Typical participants were 70 years old with mild to moderate adult-onset hearing loss bilaterally. Each participant used 4 pairs of hearing aids: premium- and basic-feature devices from brands marketed by each of two major manufacturers. Participants were blinded about the devices they used and about the research questions. Results All of the outcomes were designed to capture the participant’s point of view about the benefits of the hearing aids. Three types of data were collected: change in hearing-related quality of life, extent of agreement with six positively worded statements about everyday hearing with the hearing aids, and reported preferences between the premium- and basic-feature devices from each brand as well as across all four research hearing aids combined. None of these measures yielded

    1995-07-01

    Despite advances made in recent years in medical first aid, psychiatric intervention, survival training and equipment design, many people still perish quickly during and immediately following a disastrous event. In this study, individuals and groups of survivors of life-threatening events were debriefed and the behavior of those who coped well during such a threat to life were compared with those who did not. The behaviors of those who coped well were distilled into a set of principles for psychological first aid; that is, a series of simple actions for use within a disaster which serves to recover victims to functional behavior as quickly as possible, thus increasing their chance for survival. These principles of psychological first aid have recently been introduced into basic first aid and survival training courses for both military and civilian units.

    2005-02-01

    People living with HIV/AIDS are stigmatized. Although personal and social consequences of this stigmatization have been documented, research regarding its impact on social interactions is scarce. Latinos, and Puerto Ricans in particular, have voiced concern regarding AIDS stigma. The authors investigated the key role of social interaction in the process of stigmatization through in-depth, semistructured interviews in a sample of 30 Puerto Ricans living with HIV/AIDS. Participants reported instances in which AIDS stigma negatively influenced social interactions with family, friends, sexual partners, coworkers, and health professionals. Some of the consequences they described were loss of social support, persecution, isolation, job loss, and problems accessing health services. Findings support the need for interventions to address AIDS stigma and its consequences.

    1999-01-01

    A fundamental part of the prevention strategies aimed at reducing risk due to manual handling of patients is the use of appropriate aids. This paper defines the basic types of aids for hospital wards: patient lifting devices, aids for hygiene and minor aids; and also proposes a procedure for choice of the type of aid: the procedure uses a specific protocol and also analyzes work organization and the environmental features of the ward. The proposed criteria for choice concern in the first place the fundamental requirements of the equipment: safety for operator and patient, simplicity of use and comfort for the patient. Secondly the basic determinants for choice of the type of aid are the type of disabled patient usually present in the ward and the analysis of the movements made in handling patients. On this basis, for each type of aid, the specific features are defined which direct the choice of supply for the various wards that will be adequate and effective both in reducing risk due to manual handling of patients and in improving the comfort of the patients.

    Sufficient first aid equipment is essential to treat injuries on football fields. Deficits in first aid on field are still present in youth football. Injury pattern in youth football over one season and first aid equipment in youth football were analyzed, retrospectively. PRICE and ABC procedure served as basic principles in emergency management to assess the need for first aid equipment on field. Considering financial limits and adapted on youth football injuries, sufficient first aid equipment for youth football was configured. 84% of 73 participating youth football teams had their own first aid kit, but the majority of them were insufficiently equipped. Team coaches were in 60% of all youth teams responsible for using first aid equipment. The injury evaluation presented 922 injuries to 1,778 youth players over one season. Frequently presented types of injury were contusions and sprains of the lower extremity. Based on the analyzed injury data in youth football, first aid equipment with 90 € is sufficient for 100% of all occurred youth football injuries. Current first aid equipment in youth football is insufficient. Scientific-based first aid equipment with 90 € is adequate to serve all injuries. Football coaches need education in first aid management.

    2017-03-01

    Bone-anchored hearing aids improve hearing for patients for whom conventional behind-the-ear aids are problematic. However, uptake of bone-anchored hearing aids is low and it is important to understand why this is the case. A narrative review was conducted. Studies examining why people accept or decline bone-anchored hearing aids and satisfaction levels of people with bone-anchored hearing aids were reviewed. Reasons for declining bone-anchored hearing aids included limited perceived benefits, concerns about surgery, aesthetic concerns and treatment cost. No studies providing in-depth analysis of the reasons for declining or accepting bone-anchored hearing aids were identified. Studies of patient satisfaction showed that most participants reported benefits with bone-anchored hearing aids. However, most studies used cross-sectional and/or retrospective designs and only included people with bone-anchored hearing aids. Important avenues for further research are in-depth qualitative research designed to fully understand the decision-making process for bone-anchored hearing aids and rigorous quantitative research comparing satisfaction of people who receive bone-anchored hearing aids with those who receive alternative (or no) treatments.

  20. Operator vision aids for space teleoperation assembly and servicing

    NASA Technical Reports Server (NTRS)

    Brooks, Thurston L.; Ince, Ilhan; Lee, Greg

    1992-01-01

    This paper investigates concepts for visual operator aids required for effective telerobotic control. Operator visual aids, as defined here, mean any operational enhancement that improves man-machine control through the visual system. These concepts were derived as part of a study of vision issues for space teleoperation. Extensive literature on teleoperation, robotics, and human factors was surveyed to definitively specify appropriate requirements. This paper presents these visual aids in three general categories of camera/lighting functions, display enhancements, and operator cues. In the area of camera/lighting functions concepts are discussed for: (1) automatic end effector or task tracking; (2) novel camera designs; (3) computer-generated virtual camera views; (4) computer assisted camera/lighting placement; and (5) voice control. In the technology area of display aids, concepts are presented for: (1) zone displays, such as imminent collision or indexing limits; (2) predictive displays for temporal and spatial location; (3) stimulus-response reconciliation displays; (4) graphical display of depth cues such as 2-D symbolic depth, virtual views, and perspective depth; and (5) view enhancements through image processing and symbolic representations. Finally, operator visual cues (e.g., targets) that help identify size, distance, shape, orientation and location are discussed.

  2. Rank order scaling of pictorial depth

    van Doorn, Andrea; Koenderink, Jan; Wagemans, Johan

    2011-01-01

    We address the topic of “pictorial depth” in cases of pictures that are unlike photographic renderings. The most basic measure of “depth” is no doubt that of depth order. We establish depth order through the pairwise depth-comparison method, involving all pairs from a set of 49 fiducial points. The pictorial space for this study was evoked by a capriccio (imaginary landscape) by Francesco Guardi (1712–1793). In such a drawing pictorial space is suggested by the artist through a small set of conventional depth cues. As a result typical Western observers tend to agree largely in their visual awareness when looking at such art. We rank depths for locations that are not on a single surface and far apart in pictorial space. We find that observers resolve about 40 distinct depth layers and agree largely in this. From a previous experiment we have metrical data for the same observers. The rank correlations between the results are high. Perhaps surprisingly, we find no correlation between the number of distinct depth layers and the total metrical depth range. Thus, the relation between subjective magnitude and discrimination threshold fails to hold for pictorial depth. PMID:23145256

  4. Machine vision based teleoperation aid

    NASA Technical Reports Server (NTRS)

    Hoff, William A.; Gatrell, Lance B.; Spofford, John R.

    1991-01-01

    When teleoperating a robot using video from a remote camera, it is difficult for the operator to gauge depth and orientation from a single view. In addition, there are situations where a camera mounted for viewing by the teleoperator during a teleoperation task may not be able to see the tool tip, or the viewing angle may not be intuitive (requiring extensive training to reduce the risk of incorrect or dangerous moves by the teleoperator). A machine vision based teleoperator aid is presented which uses the operator's camera view to compute an object's pose (position and orientation), and then overlays onto the operator's screen information on the object's current and desired positions. The operator can choose to display orientation and translation information as graphics and/or text. This aid provides easily assimilated depth and relative orientation information to the teleoperator. The camera may be mounted at any known orientation relative to the tool tip. A preliminary experiment with human operators was conducted and showed that task accuracies were significantly greater with than without this aid.

    One consensus in discussions on HIV/AIDS communication in low and middle income countries (LMICs) is the need for communication models to focus on activity rather than cognitive indicators in order to achieve desired improvements in health behaviors and outcomes. Past failures of HIV/AIDS communication efforts in LMICs have been attributed to emphasis on cognitive indicators. This study analyses HIV/AIDS communication models in Nigerian newspapers. Data were obtained through analysis of manifest content of four Nigerian papers issued between 2002 and 2004. Frequency, prominence and space dedicated to HIV/AIDS-related topics were measured. Descriptive statistics were used to highlight the frequency and percentage of cognitive- and activity-oriented information on HIV/AIDS. A total of 464 HIV/AIDS-related articles were identified. Fifty-nine percent (274) of articles were activity-oriented. Over half of articles were news stories. No news story made front and back pages lead. There were only nine editorials on HIV/AIDS. This study shows that the activity model of HIV/AIDS communication dominates the four Nigerian mainstream newspapers studied. However, it is worth noting the limited number of editorials and feature articles, which have the capacity to stimulate debate and foster a social environment in which AIDS is addressed in a spirit of openness. For a country that has the third largest number of people living with HIV/AIDS globally, one would expect the mass media to deliberately play an instrumental and a more active role in the battle against the disease by engaging in in-depth contextual discourse on HIV/AIDS.

    The primary purpose of this study was to assess the role, status and scope of workplace HIV/AIDS committees as a means of effective workplace governance of the HIV/AIDS impact, and their role in extending social protective HIV/AIDS-related rights to employees. In-depth qualitative case studies were conducted in five South African small and medium-sized enterprises (SMEs) that were actively implementing HIV/AIDS policies and programmes. Companies commonly implemented HIV/AIDS policies and programmes through a workplace committee dedicated to HIV/AIDS or a generic committee dealing with issues other than HIV/ AIDS. Management, through the human resources department and the occupational health practitioner often drove initial policy formulation, and had virtually sole control of the HIV/AIDS budget. Employee members of committees were mostly volunteers, and were often production or blue collar employees, while there was a notable lack of participation by white-collar employees, line management and trade unions. While the powers of workplace committees were largely consultative, employee committee members often managed in an indirect manner to secure and extend social protective rights on HIV/AIDS to employees, and monitor their effective implementation in practice. In the interim, workplace committees represented one of the best means to facilitate more effective workplace HIV/AIDS governance. However, the increased demands on collective bargaining as a result of an anticipated rises in AIDS-related morbidity and mortality might prove to be beyond the scope of such voluntary committees in the longer term.

  14. Population differentiation decreases with depth in deep-sea gastropods

    The evolutionary processes that have generated the rich and highly endemic deep-sea benthic invertebrate fauna remain largely unstudied. Patterns of geographic variation constitute the most basic and essential information for understanding speciation and adaptive radiation. Here we present a multivariate analysis of phenotypic distance to quantify geographic variation in shell form among populations of eight deep-sea gastropod species distributed along a depth gradient in the western North Atlantic. Our primary aim is to identify regions within the deep sea that may promote population differentiation. The degree of interpopulation divergence is highest at the shelf-slope transition (200 m), and then decreases dramatically with increasing depth across the bathyal region (200-4000 m) to the abyssal plain (>4000 m). Phenotypic change parallels faunal change along the depth gradient, suggesting that the selective regime becomes more uniform with increasing depth. Results indicate that the potential for gastropod radiation within the deep-sea environment (>200 m) varies geographically and is highest in the narrow upper bathyal region.

  18. The role of eye movements in depth from motion parallax during infancy

    PubMed Central

    Nawrot, Elizabeth; Nawrot, Mark

    2013-01-01

    Motion parallax is a motion-based, monocular depth cue that uses an object's relative motion and velocity as a cue to relative depth. In adults, and in monkeys, a smooth pursuit eye movement signal is used to disambiguate the depth-sign provided by these relative motion cues. The current study investigates infants' perception of depth from motion parallax and the development of two oculomotor functions, smooth pursuit and the ocular following response (OFR) eye movements. Infants 8 to 20 weeks of age were presented with three tasks in a single session: depth from motion parallax, smooth pursuit tracking, and OFR to translation. The development of smooth pursuit was significantly related to age, as was sensitivity to motion parallax. OFR eye movements also corresponded to both age and smooth pursuit gain, with groups of infants demonstrating asymmetric function in both types of eye movements. These results suggest that the development of the eye movement system may play a crucial role in the sensitivity to depth from motion parallax in infancy. Moreover, describing the development of these oculomotor functions in relation to depth perception may aid in the understanding of certain visual dysfunctions. PMID:24353309

    ABSTRACT OBJECTIVE To analyze the genesis of the policy for controlling AIDS in Brazil. METHODS Socio-historical study (1981-1989), based on Bordieu’s genetic sociology, by document analysis, bibliographical review, and in-depth interviews. It consisted of a connection between the analysis of the paths of 33 agents involved in the creation of a social space focusing on AIDS-related issues and the historical possibility conditions of the drafting of a specific policy. RESULTS AIDS Space is a gathering point for the paths of agents from several social fields (medical, scientific, political, and bureaucratic fields). A specific space for relationships, which enabled the drafting of a policy for controlling the AIDS epidemic, but also a place where the authority to talk about the meaning of the disease, the methods to prevent and treat it was under dispute. The analysis showed how the various structures (democratic administrations in Sao Paulo and at the national level, with public health officers taking important positions) and the lack of a specific therapy contributed to social agents of different ranks and backgrounds to initially set prevention as a priority. CONCLUSIONS The rise of the sanitary movement, the organization of SUS, and the dominance of the medical field at the AIDS Space contributed to foster treatment as a part of the measures to control the epidemic. These conditions allowed drafting a policy based on the integrality of care, by linking prevention and treatment in the following decade, with important participation from state bureaucracy and researchers.

    Health-related quality of life (HRQoL) is increasingly recognized as an important outcome and as a complement to traditional biological end points of diseases such as mortality. Unless there is a complete cure available for HIV/AIDS, development and implementation of a reliable and valid cross cultural quality of life measure is necessary to assess not only the physical and medical needs of HIV/AIDS people, but their psychological, social, environmental, and spiritual areas of life. A qualitative exploration of HIV/AIDS patients' understanding, perceptions and expectations will be carried out with the help of semi structured interview guide by in depth interviews, while quantitative assessment of patient reported adverse drug reactions and their impact on health related quality of life will be carried out by using data collection tool comprising patient demographics, SF-12, Naranjo scale, and a clinical data sheet. The findings may serve as baseline QOL data of people living with HIV/AIDS in Malaysia and also a source data to aid construction of management plan to improve HIV/AIDS patients' QOL. It will also provide basic information about HIV/AIDS patients' perceptions, expectations and believes towards HIV/AIDS and its treatment which may help in designing strategies to enhance patients' awareness which in turn can help in addressing issues related to compliance and adherence. © 2013 John Wiley & Sons Ltd.

    2010-01-01

    Objectives To develop and assess the reliability of a script concordance test (SCT) to evaluate pharmacy students' clinical reasoning when facing basic emergency situations. Design A first aid course was designed that consisted of 8 weekly instructional sessions (4 on internal medicine, including life threatening situations; 2 on pediatrics; and 2 on trauma) in which the instructor presented case studies in a small-group format. In the first and final sessions of the course, a practice SCT was administered to familiarize students with the test format. Assessment A 66-question SCT examination was administered to the 68 third-year pharmacy students enrolled in the first aid course. The students' mean score was 68.5% ± 9.8% and panel members' mean score was 86.5% ± 4.2%. Twenty students were selected randomly to complete a course survey and 85% indicated they were satisfied with using the SCT. Conclusions A first aid SCT was found to be both a practical and reliable testing instrument for assessing the clinical reasoning of pharmacy students in basic emergency situations. PMID:21436943

    As the number of children orphaned by AIDS (Acquired Immunodeficiency Syndrome) has reached 17.3 million, most living in resource-poor settings, interest has grown in identifying and evaluating appropriate care arrangements for them. In this study, we describe the community-based family-style group homes (‘group homes’) in rural China. Guided by an ecological framework of children’s wellbeing, we conducted a series of ethnographic observations, in-depth interviews and group discussions in the rural areas of Henan Province, which has been severely impacted by the AIDS endemic through commercial blood collection. Based on our observations and discussions, group homes appear to provide stable and safe living environments for children orphaned by AIDS. Adequate financial support from non-government organizations (NGOs) as well as the central and provincial governments has ensured a low child–caregiver ratio and attention to the basic needs of the children at group homes. The foster parents were selected from the local community and appear to have adequate qualifications and dedication. They receive a monthly stipend, periodical evaluation and parenting consultation from supporting NGOs. The foster parents and children in the group homes have formed strong bonds. Both children and foster parents reported positively on health and education. Characteristics of community-based group homes can be replicated in other care arrangements for AIDS orphans in resource-poor settings for the optimal health outcomes of those vulnerable children. We also call for capacity building for caregivers and communities to provide sustainable and supportive living environment for these children. PMID:25124083

    2004-01-01

    In 2001, it was estimated that 4.7 million South Africans were living with HIV/AIDS. Prevalence figures have risen steadily over the past 10 years in most African countries, and in only a few, like Uganda, does the epidemic show signs of waning. In Africa, the status of the obese has risen enormously. If you're fat, you don't have AIDS. The epidemic is fuelled by many factors. These include: a lack of basic education about HIV risk; migrant labour disrupting family stability; polygamous marriages; patriarchal practices; and a lack of basic human rights, including being able to refuse intercourse, for women. Health care systems struggle and fail to cope with overwhelming demands, and the scale of the human loss risks dehumanising carers and health workers. Doctors evolve coping strategies, as do health systems and governments. Aid from the Western world has, until recently, been tokenistic in scale. HIV/AIDS in Africa is substantially a result of the socioeconomic and political realities of the past and present, and is related to the continued exploitation of developing countries by developed nations. This article was the introductory paper in the 'HIV/AIDS in the Developing World workshop' of the 2003 WONCA World Rural Health Congress, Santiago de Compostela, Spain. The concluding 'Santiago de Compostela Statement on HIV/AIDS' was adopted at the congress, and is offered here as a suggested way forward.

  7. Oklahoma's induced seismicity strongly linked to wastewater injection depth

    2018-03-01

    The sharp rise in Oklahoma seismicity since 2009 is due to wastewater injection. The role of injection depth is an open, complex issue, yet critical for hazard assessment and regulation. We developed an advanced Bayesian network to model joint conditional dependencies between spatial, operational, and seismicity parameters. We found that injection depth relative to crystalline basement most strongly correlates with seismic moment release. The joint effects of depth and volume are critical, as injection rate becomes more influential near the basement interface. Restricting injection depths to 200 to 500 meters above basement could reduce annual seismic moment release by a factor of 1.4 to 2.8. Our approach enables identification of subregions where targeted regulation may mitigate effects of induced earthquakes, aiding operators and regulators in wastewater disposal regions.

    Gaintantzopoulou, M D; El-Damanhoury, H M

    The aim of the study was to evaluate the effect of preparation depth and intraradicular extension on the marginal and internal adaptation of computer-aided design/computer-assisted manufacture (CAD/CAM) endocrown restorations. Standardized preparations were made in resin endodontic tooth models (Nissin Dental), with an intracoronal preparation depth of 2 mm (group H2), with extra 1- (group H3) or 2-mm (group H4) intraradicular extensions in the root canals (n=12). Vita Enamic polymer-infiltrated ceramic-network material endocrowns were fabricated using the CEREC AC CAD/CAM system and were seated on the prepared teeth. Specimens were evaluated by microtomography. Horizontal and vertical tomographic sections were recorded and reconstructed by using the CTSkan software (TView v1.1, Skyscan).The surface/void volume (S/V) in the region of interest was calculated. Marginal gap (MG), absolute marginal discrepancy (MD), and internal marginal gap were measured at various measuring locations and calculated in microscale (μm). Marginal and internal discrepancy data (μm) were analyzed with nonparametric Kruskal-Wallis analysis of variance by ranks with Dunn's post hoc, whereas S/V data were analyzed by one-way analysis of variance and Bonferroni multiple comparisons (α=0.05). Significant differences were found in MG, MD, and internal gap width values between the groups, with H2 showing the lowest values from all groups. S/V calculations presented significant differences between H2 and the other two groups (H3 and H4) tested, with H2 again showing the lowest values. Increasing the intraradicular extension of endocrown restorations increased the marginal and internal gap of endocrown restorations.

    Bystanders can play an important role in the event of sudden injury or illness. Our aim was to evaluate the effects of a 3-day first aid course for all primary school age groups (7-14 years old). 582 school children were involved in the study. Training consisted of three sessions with transfer of theoretical knowledge and practical skills about first aid. The following most urgent situations were addressed in our study: adult basic life support (BLS), using an automated external defibrillator (AED), handling an unconscious patient, managing bleeding and calling the ambulance. Data collection was made with a questionnaire developed for the study and observation. Students were tested before, immediately after and 4 months after training. Results were considered significant in case of p<0.05. Prior to training there was a low level of knowledge and skills on BLS, management of the unconscious patient, use of an AED and management of bleeding. Knowledge and skills improved significantly in all of these categories (p<0.01) and remained significantly higher than the pre-test level at 4 months after training (p<0.01). Younger children overall performed less well than older children, but significantly improved over the pre-test level both immediately and 4 months after training (p<0.01). Prior first aid training was associated with knowledge of the correct ambulance number (p=0.015) and management of bleeding (p=0.041). Prior to training, age was associated with pre-test knowledge and skills of all topics (p<0.01); after training, it was only associated with AED use (p<0.001). There was a significant correlation between the depth of chest compression and children's age, weight, height and body mass index (p<0.001). Ventilation depended on the same factors (p<0.001). Children aged 7-14 years are able to perform basic life-saving skills. Knowledge retention after 4 months is good for skills, but thinking in algorithms is difficult for these children. © Article author(s) (or

    We explore how marital aspirations are related to the sexual behaviors of adolescents and young adults in Malawi, where HIV/AIDS prevalence among adults exceeds 10%. We also consider whether the specter of AIDS is shaping ideals about marriage. By combining survey data (N = 1,087) and in-depth interviews (N = 133) with young Malawians from the Malawi Diffusion and Ideational Change Project, we show that looking for and finding a suitable spouse are linked to sexual behaviors and, thus, HIV risks. Moreover, concerns about contracting HIV are closely tied to the ideal characteristics of a future spouse. Our findings draw long-overdue attention to the importance of marital aspirations in understanding adolescent sexual behaviors and risks in the era of AIDS. PMID:20161389

    1987-04-04

    In response to concern over the perceived limited effectiveness of Department of Health and Social Security (UK) advertising campaigns to inform the public of the basic facts of Acquired Immunodeficiency Syndrome (AIDS), a prospective questionnaire study was undertaken in Southampton, England to test the effectiveness of government education prior to a January, 1987 government television/leaflet advertising campaign. 300 questionnaires about AIDS were mailed in December of 1986 to a sample drawn from electoral rolls. The response rate was 61%. Most of the questions were drawn from material covered in the campaign. The results seemed to indicate a small overall increase in knowledge about AIDS. Some changes from a June survey were noted, e.g.: more people were aware that AIDS is a virus for which there is no cure and that it is not readily transmitted by sharing washing, eating or drinking utensils; more people believed that the statement that women are at greater risk for catching AIDS is false. Respondents were generally favorable to the government's continued use of television, even with explicit language, and to its use of the schools, for AIDS education. Many were not aware of the dangers to intravenous drug users or of the symptoms of AIDS. Other surveys have shown an increasing knowledge of AIDS dangers. It is possible that television coverage of the problem will continue to be necessary, in order that less literate populations be reached. Further AIDS health education in general is needed.

    RATIONALE AND KEY POINTS: This article aims to help nurses to perform first aid in a safe, effective and patient-centred manner. First aid comprises a series of simple, potentially life-saving steps that an individual can perform with minimal equipment. Although it is not a legal requirement to respond to an emergency situation outside of work, nurses have a professional duty to respond and provide care within the limits of their competency. First aid is the provision of immediate medical assistance to an ill or injured person until definitive medical treatment can be accessed. First aid can save lives and it is essential that nurses understand the basic principles. REFLECTIVE ACTIVITY: Clinical skills articles can help update your practice and ensure it remains evidence based. Apply this article to your practice. Reflect on and write a short account of: 1. Your skill in performing first aid and any areas where you may need to extend your knowledge. 2. How reading this article will change your practice.

    A successful short-term solution to transmission of AIDS in Western Africa by migrants involves provision of accessible and acceptable basic health and social services to migrants at their destination. The aim is to establish a sense of security and community, which is a health requirement. When migrants are excluded from community life or victimized as carriers of HIV infections, they will be driven by basic survival needs and dysfunctional social organization, which results in the rapid spread of HIV. Closing borders and mass deportation may not be an option. The long-term solution is population policy, environmental protection, and economic development. The focus on mapping the spread of AIDS must shift to a consideration of the migrant social conditions that make them vulnerable to AIDS. The issue of migration and AIDS will be addressed at the First European Conference on Tropical Medicine in October 1995 in Hamburg, Germany. In Uganda, HIV seroprevalence rates ranged from 5.5% among the stable population to 12.4% among internal migrants moving between villages to 16.3% among migrants from other areas. A World Bank project is operating in Western Africa, which traces seasonal male migration from the Cameroon to Liberia, Senegal to Nigeria, and from the Sahel to the coast during dry seasons. National border rules may influence the routes but not the extent of migration. A major destination place is Cote d' Ivoire, which has 25% of total population comprised of migrants from other countries and one of the highest HIV prevalence rates in Western Africa. On plantations prostitutes are brought in. Each prostitute serves about 25 workers. The pattern of sexual mixing contributes to the high HIV rates. Female migration is smaller and usually concentrated in prostitution at place of destination. Illiteracy and poverty drive women migrants into the trade. Their frequent health problems are malaria, pelvic pain, menstrual irregularity, vaginal discharge, and genital

  10. Measuring depth profiles of residual stress with Raman spectroscopy

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Enloe, W.S.; Sparks, R.G.; Paesler, M.A.

    Knowledge of the variation of residual stress is a very important factor in understanding the properties of machined surfaces. The nature of the residual stress can determine a part`s susceptibility to wear deformation, and cracking. Raman spectroscopy is known to be a very useful technique for measuring residual stress in many materials. These measurements are routinely made with a lateral resolution of 1{mu}m and an accuracy of 0.1 kbar. The variation of stress with depth; however, has not received much attention in the past. A novel technique has been developed that allows quantitative measurement of the variation of the residualmore » stress with depth with an accuracy of 10nm in the z direction. Qualitative techniques for determining whether the stress is varying with depth are presented. It is also demonstrated that when the stress is changing over the volume sampled, errors can be introduced if the variation of the stress with depth is ignored. Computer aided data analysis is used to determine the depth dependence of the residual stress.« less

    Knowledge of first aid, which constitutes life-saving treatments for injuries or unexpected illnesses, is important for every individual at every age. First aid and basic life support are so important that teaching basic first aid should be compulsory in all schools. The goal of this study was to determine the knowledge and attitudes of a sample of Turkish teachers regarding the administration of first aid. Three hundred twelve teachers took part in this study to evaluate knowledge and attitudes of teachers in primary schools about first aid. Data were obtained using a questionnaire. It included 30 questions that help identify the teachers and determine their knowledge and attitudes about first aid. Data were analyzed by chi-square test. In this study, it was determined that most of the teachers do not have correct knowledge and attitudes about first aid. For example, 65.1% of teachers gave incorrect answers regarding epistaxis, 63.5% for bee stings, and 88.5% for abrasion. It was found out that as the age of the teachers increases, appropriate first-aid practice becomes more and more unlikely. The results of this study showed that teachers did not have enough knowledge about first aid.

    In 1999, An Oral Health Survey of American Indian and Alaska Native (AI/AN) Dental Patients found that 79% of 2- to 5-year-olds had a history of tooth decay. The Alaska Native Tribal Health Consortium in collaboration with Alaska's Tribal Health Organizations (THO) developed a new and diverse dental workforce model to address AI/AN oral health disparities. This paper describes the workforce model and some experience to date of the Dental Health Aide (DHA) Initiative that was introduced under the federally sanctioned Community Health Aide Program in Alaska. These new dental team members work with THO dentists and hygienists to provide education, prevention and basic restorative services in a culturally appropriate manner. The DHA Initiative introduced 4 new dental provider types to Alaska: the Primary Dental Health Aide, the Expanded Function Dental Health Aide, the Dental Health Aide Hygienist and the Dental Health Aide Therapist. The scope of practice between the 4 different DHA providers varies vastly along with the required training and education requirements. DHAs are certified, not licensed, providers. Recertification occurs every 2 years and requires the completion of 24 hours of continuing education and continual competency evaluation. Dental Health Aides provide evidence-based prevention programs and dental care that improve access to oral health care and help address well-documented oral health disparities.

    Canada’s nursing homes have become increasingly dependent on immigrant health care aides. More than any other ethnic group, Filipino women are over-represented among health care aides in the Canadian health care system. This qualitative study explored the employment experiences of Filipino health care aides in nursing homes from their own perspectives as well as those of policy stakeholders. Fourteen in-depth interviews were conducted with Filipino health care aides and long-term-care policy stakeholders in Winnipeg, Manitoba. The results indicated that migrant social networks act as pathways linking immigrant women with employment opportunities in nursing homes. The composition of the labour force is also shaped by management strategies and labour market accommodations that respond to, and reinforce, these social networks. These findings have implications for workforce planning and the quality of care provision in nursing homes.

    1997-09-01

    Since HIV is sexually transmitted, people living with AIDS and HIV (PWA/PHA) risk being stigmatized as immoral and promiscuous and they are often discriminated against in society. To this effect, the South African AIDS Law Project and Lawyers for Human Rights have developed a comprehensive resource manual detailing human rights with a special emphasis on issues relevant to PWA/PHA. The concept of the manual aimed to look at the legal and human rights questions that have been raised by the HIV/AIDS epidemic; inform people living with HIV/AIDS about their rights and the law; provide people working in businesses, trade unions, and nongovernmental organization with information about correct and incorrect responses to HIV/AIDS; and give victims of discrimination ideas on how to fight back. This manual initially introduces basic facts about HIV and AIDS and then describes the legal system and the Bill of Rights within the new South African Constitution. The main areas of focus in the manual include: 1) patient's medical rights, 2) employment rights, 3) women's rights, 4) the rights of lesbians and gay men, 5) the rights of youth and children, 6) the rights of prisoners, 7) social support for PWA, 8) HIV/AIDS and insurance law, 9) power of attorney and making wills, 10) criminal law, and 11) legal remedies, such as using the law to protect one's rights.

    Human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) is pandemic. It has affected nearly 60 million people since the detection of the disease in 1981 to date. In this paper basic deterministic HIV/AIDS model with mass action incidence function are developed. Stability analysis is carried out. And the disease free equilibrium of the basic model was found to be locally asymptotically stable whenever the threshold parameter (RO) value is less than one, and unstable otherwise. The model is extended by introducing two optimal control strategies namely, CD4 counts and treatment for the infective using optimal control theory. Numerical simulation was carried out in order to illustrate the analytic results.

    Large-scale molecular dynamics simulation is performed to study the nano-cutting process of single crystal copper realized by single-point diamond cutting tool in this paper. The centro-symmetry parameter is adopted to characterize the subsurface deformed layers and the distribution and evolution of the subsurface defect structures. Three-dimensional visualization and measurement technology are used to measure the depth of the subsurface deformed layers. The influence of cutting speed, cutting depth, cutting direction, and crystallographic orientation on the depth of subsurface deformed layers is systematically investigated. The results show that a lot of defect structures are formed in the subsurface of workpiece during nano-cutting process, for instance, stair-rod dislocations, stacking fault tetrahedron, atomic clusters, vacancy defects, point defects. In the process of nano-cutting, the depth of subsurface deformed layers increases with the cutting distance at the beginning, then decreases at stable cutting process, and basically remains unchanged when the cutting distance reaches up to 24 nm. The depth of subsurface deformed layers decreases with the increase in cutting speed between 50 and 300 m/s. The depth of subsurface deformed layer increases with cutting depth, proportionally, and basically remains unchanged when the cutting depth reaches over 6 nm.

    Bystander first aid and basic life support can likely improve victim survival in trauma. In contrast to bystander first aid and out-of-hospital cardiac arrest, little is known about the role of bystanders in trauma response. Our aim was to determine how frequently first aid is given to trauma victims by bystanders, the quality of this aid, the professional background of first-aid providers, and whether previous first-aid training affects aid quality. We conducted a prospective 18-month study in two mixed urban-rural Norwegian counties. The personnel on the first ambulance responding to trauma calls assessed and documented first aid performed by bystanders using a standard form. A total of 330 trauma calls were included, with bystanders present in 97% of cases. Securing an open airway was correctly performed for 76% of the 43 patients in need of this first-aid measure. Bleeding control was provided correctly for 81% of 63 patients for whom this measure was indicated, and prevention of hypothermia for 62% of 204 patients. Among the first-aid providers studied, 35% had some training in first aid. Bystanders with documented first-aid training gave better first aid than those where first-aid training status was unknown. A majority of the trauma patients studied received correct pre-hospital first aid, but still there is need for considerable improvement, particularly hypothermia prevention. Previous first-aid training seems to improve the quality of first aid provided. The effect on patient survival needs to be investigated. © 2015 The Authors.

    Bystander first aid can improve survival following out-of-hospital cardiac arrest or trauma. Thus, providing first aid education to laypersons may lead to better outcomes. In this study, we aimed to establish the prevalence and distribution of first aid training in the populace, how often first aid skills are needed, and self-reported helping behaviour. We conducted a telephone survey of 1000 respondents who were representative of the Norwegian population. Respondents were asked where and when they had first aid training, if they had ever encountered situations where first aid was necessary, and stratified by occupation. First aid included cardio-pulmonary resuscitation (CPR) and basic life support (BLS). To test theoretical first aid knowledge, respondents were subjected to two hypothetical first aid scenarios. Among the respondents, 90% had received first aid training, and 54% had undergone first aid training within the last 5 years. The workplace was the most common source of first aid training. Of the 43% who had been in a situation requiring first aid, 89% had provided first aid in that situation. There were considerable variations among different occupations in first aid training, and exposure to situations requiring first aid. Theoretical first aid knowledge was not as good as expected in light of the high share who had first aid training. In the presented scenarios 42% of respondent would initiate CPR in an unconscious patient not breathing normally, and 46% would provide an open airway to an unconscious road traffic victim. First aid training was correlated with better theoretical knowledge, but time since first aid training was not. A high proportion of the Norwegian population had first aid training, and interviewees reported high willingness to provide first aid. Theoretical first aid knowledge was worse than expected. While first aid is part of national school curriculum, few have listed school as the source for their first aid training.

    Background: HIV is a multidimensional problem. Therefore, prioritization of research topics in this field is a serious challenge. We decided to prioritize the major areas of research on HIV/AIDS in Iran. Materials ans Methods: In a brain-storming session with the main national and provincial stakeholders and experts from different relevant fields, the direct and indirect dimensions of HIV/AIDS and its related research issues were explored. Afterward, using the Delphi method, we sent questionnaires to 20 experts (13 respondents) from different sectors. In this electronic based questioner, we requested experts to evaluate main topics and their subtopics. The ranges of scores were between 0 and 100. Results: The score of priorities of main themes were preventive activities (43.2), large scale planning (25.4), the estimation of the HIV/AIDS burden (20.9), and basic scientific research (10.5). The most important priority in each main theme was education particularly in high risk groups (52.5), developing the national strategy to address the epidemic (31.8), estimation of the incidence and prevalence among high-risk groups (59.5) and developing new preventive methods (66.7), respectively. Conclusions: The most important priorities of researches on HIV/AIDS were preventive activities and developing national strategy. As high risk groups are the most involved people in the epidemic, and they are also the most hard-to-reach sub-populations, a national well designated comprehensive strategy is essential. However, we believe with a very specific and directed scheme, special attention to research in basic sciences is necessary, at least in limited number of institutes. PMID:23626616

    To investigate the prevalence and determinants of student and parental attitudes toward the education of children affected by HIV/AIDS in areas of rural China where AIDS is prevalent. A cross-sectional study of a random sample of students (n=732) and their parents (n=732) conducted in April 2010, using a questionnaire and in-depth interview. Twenty-six per cent of students and 29% of parents had a 'good' attitude toward the education of children affected by HIV/AIDS. Following adjustment for sociodemographic characteristics, students' attitudes were significantly associated with knowledge of HIV/AIDS non-transmission (adjusted odds ratio [aOR]= 3.13) and their parents' attitudes (aOR= 2.38), but not with knowledge of HIV/AIDS transmission, prevention or their parents' knowledge. Parents' attitudes were significantly associated with knowledge of HIV/AIDS non-transmission (aOR= 2.12) and their children's attitudes (aOR= 2.52), but not with knowledge of HIV/AIDS transmission, prevention or their children's knowledge. Stigma and discrimination undermine the right to education of HIV/AIDS-affected children in rural China. Improving non-transmission knowledge may improve caring attitudes. HIV/AIDS public health educational campaigns highlighting non-transmission and extending family education, combined with school education, may help to enhance an environment of non-discrimination and safeguard public support programs for the right to education of children affected by HIV/AIDS. © 2013 The Authors.

    1) Examine angular insertion depths (AID) and scalar location of Med-El (GmbH Innsbruck, Austria) electrodes; and 2) determine the relationship between AID and audiologic outcomes controlling for scalar position. Retrospective review. Postlingually deafened adults undergoing cochlear implantation with Flex 24, Flex 28, and Standard electrode arrays (Med-El) were identified. Patients with preoperative and postoperative computed tomography scans were included so that electrode location and AID could be determined. Outcome measures were 1) speech perception in the cochlear implant (CI)-only condition, and 2) short-term hearing preservation. Forty-eight implants were included; all electrodes (48 of 48) were positioned entirely within the scala tympani. The median AID was 408° (interquartile [IQ] range 373°-449°) for Flex 24, 575° (IQ range 465°-584°) for Flex 28, and 584° (IQ range 368°-643°) for Standard electrodes (Med-El). The mean postoperative CNC score was 43.7% ± 21.9. A positive correlation was observed between greater AID and better CNC performance (r = 0.48, P < 0.001). Excluding patients with postoperative residual hearing, a strong correlation between AID and CNC persisted (r = 0.57, P < 0.001). In patients with preoperative residual hearing, mean low-frequency pure-tone average (PTA) shift was 27 dB ± 14. A correlation between AID and low-frequency PTA shift at activation was noted (r = 0.41, P = 0.04). Favorable rates of scala tympani insertion (100%) were observed. In the CI-only condition, a direct correlation between greater AID and CNC score was noted regardless of postoperative hearing status. Deeper insertions were, however, associated with worse short-term hearing preservation. When patients without postoperative residual hearing were analyzed independently, the relationship between greater insertion depth and better performance was strengthened. 4.

    Sub-Saharan Africa is most affected by the AIDS pandemic and Lesotho is no exception. In many countries, healthcare workers are at the forefront of the fight against AIDS. This study explores the difficulties facing healthcare workers in Lesotho using a combination of qualitative methods--focus group discussions and in-depth interviews. The findings suggest that healthcare workers are afraid of contracting HIV from their patients and this affects their delivery of services. In addition, the results revealed that poor infrastructure and shortage of supplies at the facilities hinder healthcare workers from performing their duties effectively. The other concern was the heavy workload and severe time constraints which puts enormous stress on healthcare workers. Stigma and discrimination emerged as major problems for healthcare workers. Addressing the challenges facing healthcare workers is essential in effectively managing the AIDS pandemic facing the continent.

    Drawing on the Greater Involvement of People with HIV/AIDS (GIPA) principle, the HIV/AIDS movement began to "democratize" research in Canada in the mid-1990s. To date, there is little evidence about the success of the community-based research (CBR) movement in relation to the implementation of GIPA. We draw on findings from a larger study examining barriers and facilitating factors in relation to HIV-related CBR in Ontario, Canada. An online survey was completed by 39 senior managers in Ontario AIDS service organizations (ASOs). Twenty-five in-depth, semi-structured interviews were then conducted to further explore the survey findings. Survey respondents reported that, compared to researchers and frontline service providers, people living with HIV/AIDS (PLWHA) tended to be the least involved in all stages (input, process and outcome) of CBR projects. AIDS service organizations with a mandate that included serving rural and urban communities reported even lower levels of PLWHA involvement in CBR. Qualitative data reveal complex barriers that make meaningful PLWHA engagement in CBR difficult, including: HIV-related stigma; health-related challenges; "credentialism"; lack of capacity to engage in research; other issues taking priority; and mistrust of researchers. Facilitating factors included valuing lived experience; training and mentoring opportunities; financial compensation; trust building; and accommodating PLWHA's needs. While there is strong support for the GIPA principles in theory, practice lags far behind.

  13. Use of microcomputer in mapping depth of stratigraphic horizons in National Petroleum Reserve in Alaska

    USGS Publications Warehouse

    Payne, Thomas G.

    1982-01-01

    REGIONAL MAPPER is a menu-driven system in the BASIC language for computing and plotting (1) time, depth, and average velocity to geologic horizons, (2) interval time, thickness, and interval velocity of stratigraphic intervals, and (3) subcropping and onlapping intervals at unconformities. The system consists of three programs: FILER, TRAVERSER, and PLOTTER. A control point is a shot point with velocity analysis or a shot point at or near a well with velocity check-shot survey. Reflection time to and code number of seismic horizons are filed by digitizing tablet from record sections. TRAVERSER starts at a point of geologic control and, in traversing to another, parallels seismic events, records loss of horizons by onlap and truncation, and stores reflection time for geologic horizons at traversed shot points. TRAVERSER is basically a phantoming procedure. Permafrost thickness and velocity variations, buried canyons with low-velocity fill, and error in seismically derived velocity cause velocity anomalies that complicate depth mapping. Two depths to the top of the pebble is based shale are computed for each control point. One depth, designated Zs on seismically derived velocity. The other (Zw) is based on interval velocity interpolated linearly between wells and multiplied by interval time (isochron) to give interval thickness. Z w is computed for all geologic horizons by downward summation of interval thickness. Unknown true depth (Z) to the pebble shale may be expressed as Z = Zs + es and Z = Zw + ew where the e terms represent error. Equating the two expressions gives the depth difference D = Zs + Zw = ew + es A plot of D for the top of the pebble shale is readily contourable but smoothing is required to produce a reasonably simple surface. Seismically derived velocity used in computing Zs includes the effect of velocity anomalies but is subject to some large randomly distributed errors resulting in depth errors (es). Well-derived velocity used in computing Zw

    Interactive x-ray simulations of complex computer-aided design (CAD) models can provide valuable insights for better interpretation of the defect signatures such as porosity from x-ray CT images. Generating the depth map along a particular direction for the given CAD geometry is the most compute-intensive step in x-ray simulations. We have developed a GPU-accelerated method for real-time generation of depth maps of complex CAD geometries. We preprocess complex components designed using commercial CAD systems using a custom CAD module and convert them into a fine user-defined surface tessellation. Our CAD module can be used by different simulators as well as handle complex geometries, including those that arise from complex castings and composite structures. We then make use of a parallel algorithm that runs on a graphics processing unit (GPU) to convert the finely-tessellated CAD model to a voxelized representation. The voxelized representation can enable heterogeneous modeling of the volume enclosed by the CAD model by assigning heterogeneous material properties in specific regions. The depth maps are generated from this voxelized representation with the help of a GPU-accelerated ray-casting algorithm. The GPU-accelerated ray-casting method enables interactive (> 60 frames-per-second) generation of the depth maps of complex CAD geometries. This enables arbitrarily rotation and slicing of the CAD model, leading to better interpretation of the x-ray images by the user. In addition, the depth maps can be used to aid directly in CT reconstruction algorithms.

  17. Making the connections: AIDS and water.

    2006-01-01

    Acknowledging AIDS as a crosscutting development issue, a Zambian rural water supply project that provides safe accessible water to rural communities embarked on a new initiative to mainstream AIDS into the water sector. The work of providing safe water takes the predominantly male workforce away from their spouses and families, into the rural villages of Zambia's Eastern Province, for long periods of time. With an HIV prevalence rate of 16.1%, the risk of HIV exposure exists for both employees and rural villagers. AIDS mainstreaming activities were designed to target both groups. An AIDS mainstreaming strategy was developed by identifying components that could be influenced in the external domain (the organization's usual work) and the internal domain (the workplace). Basic questions were addressed such as: how does AIDS affect the organization, how might the usual work aggravate susceptibility to HIV infection, and where is the comparative advantage? A workplace program including peer education, employee health education (including condoms) and a workplace policy was established for employees. For the target population, a series of five messages connecting safe water and AIDS was developed and disseminated through educational drama, community meetings and trainings, and integrated into the regular water, sanitation and hygiene activities. As an efficient utilization of resources that makes a broad impact, AIDS mainstreaming does not change the sector's mandate but takes advantage of the extensive geographic coverage and natural distribution system of water projects to disseminate AIDS information and make linkages with AIDS partners.

  18. Value-based design for the elderly: An application in the field of mobility aids.

    In the aging society, the need for the elderly to remain mobile and independent is higher than ever. However, many aids supporting mobility often fail to target real needs and lack acceptance. The aim of this study is to demonstrate how value-based design can contribute to the design of mobility aids that address real needs and thus, lead to high acceptance. We elicited values, facilitators, and barriers of mobility of older adults via ten in-depth interviews. Next, we held co-creation sessions, resulting in several designs of innovative mobility aids, which were evaluated for acceptance via nine in-depth interviews. The interviews resulted in a myriad of key values, such as "independence from family" and "doing their own groceries." Design sessions resulted in three designs for a wheeled walker. Their acceptance was rather low. Current mobility device users were more eager to accept the designs than non-users. The value-based approach offers designers a close look into the lives of the elderly, thereby opening up a wide range of innovation possibilities that better fit their actual needs. Product service systems seem to be a promising focus for targeting human needs in mobility device design.

  19. Short-term visual memory for location in depth: A U-shaped function of time.

    PubMed

    Reeves, Adam; Lei, Quan

    2017-10-01

    Short-term visual memory was studied by displaying arrays of four or five numerals, each numeral in its own depth plane, followed after various delays by an arrow cue shown in one of the depth planes. Subjects reported the numeral at the depth cued by the arrow. Accuracy fell with increasing cue delay for the first 500 ms or so, and then recovered almost fully. This dipping pattern contrasts with the usual iconic decay observed for memory traces. The dip occurred with or without a verbal or color-shape retention load on working memory. In contrast, accuracy did not change with delay when a tonal cue replaced the arrow cue. We hypothesized that information concerning the depths of the numerals decays over time in sensory memory, but that cued recall is aided later on by transfer to a visual memory specialized for depth. This transfer is sufficiently rapid with a tonal cue to compensate for the sensory decay, but it is slowed by the need to tag the arrow cue's depth relative to the depths of the numerals, exposing a dip when sensation has decayed and transfer is not yet complete. A model with a fixed rate of sensory decay and varied transfer rates across individuals captures the dip as well as the cue modality effect.

    The China Ministry of Health has estimated that there are at least 100,000 AIDS orphans in China. The UNICEF China Office estimates that between 150,000 and 250,000 additional children will be orphaned by AIDS over the next five years. However, limited data are available regarding the sociodemographic characteristics, care arrangements, barriers to appropriate grief resolution and psychological problems among AIDS orphans in China. In this article, we review secondary data and reports from scientific literature, government, non-governmental organisations and public media regarding children orphaned by AIDS in China to address their living situation, bereavement process and psychological problems. Our review suggests that AIDS orphans in China are living in a stressful environment, with many orphans struggling with psychological problems and unmet basic needs such as food, shelter, education and medical care. Based on our review, we suggest that future studies should address the psychosocial needs of AIDS orphans in China and develop health promotion programmes to mitigate the negative impact of parental death on the physical and psychosocial well-being of these orphans.

    The purpose of this study was to compare two different methods to teach educators about HIV/AIDS. Sixty educators were selected from eight schools in KwaZulu-Natal Province, South Africa, to undergo HIV/AIDS training using an interactive CD-ROM intervention. Another sixty educators from other schools were selected to undergo a two-day Care & Support Training Programme provided by the Department of Education. The outcomes both before and after the interventions were measured by surveying the educators’ knowledge and attitudes related to HIV/AIDS, as well as their self-efficacy with respect to dealing with HIV/AIDS in the classroom setting. Both interventions resulted in significant changes in knowledge and attitudes as well as in the self-efficacy with respect to ability to teach about HIV/AIDS and to deal with classroom situations involving HIV and blood. The Care & Support Training Programme proved superior in enhancing basic knowledge about HIV, and the CD-ROM was superior in teaching about HIV transmission risks. PMID:20852677

    The objective of this study was to analyze the scientific production on health interventions related to hygiene for adults with HIV/AIDS. An integrative literature review was performed using six databases in June 2013. The descriptors AIDS and Hygiene were used, in Portuguese, English or Spanish. A total of 682 articles were found and 16 were selected. Personal hygiene practices were identified, such as hand washing, showers, tooth brushing and quitting smoking. Food hygiene practices involved washing food and kitchen utensils, using treated water, conserving and cooking food. Environmental hygiene took into account raising domestic animals, control of disease vectors, household cleanliness, waste disposal and basic sanitation. In conclusion, these specific hygiene interventions can be applied to the general population and, especially, to people with HIV/AIDS, due to immunosuppression.

    This study examines facial tissue depth in Canadian Aboriginal children. Using ultrasound, measurements were taken at 19 points on the faces of 392 individuals aged 3-18 years old. The relationships between tissue thickness, age, and sex were investigated. A positive linear trend may exist between tissue thickness and age for Aboriginal females and males at multiple points. No points show significant differences in facial tissue depth between males and females aged 3-8 years old; seven points show significant differences in facial tissue depth between males and females aged 9-13 years old; and five points show significant differences in facial tissue depth between males and females aged 14-18 years old. Comparisons were made with White Americans and African Nova Scotians. These data can assist in 3-D facial reconstructions and aid in establishing an individual's identity. Previously, no data existed for facial tissue thickness in Canadian Aboriginal populations. © 2013 American Academy of Forensic Sciences.

Students completed a questionnaire recommended by UNAIDS in order to develop basic indicators. the indicator of preventive sexual practices related to HIV/AIDS was 32.5%; forms of prevention (62.5%) were better known than erroneous ideas about transmission (46%). Adolescents from the only private school in the study demonstrated greater knowledge (43.3%) than students from the public schools (25%) (p<0.01). No significant differences were found in knowledge according to age, sex or educational level. adolescents have poor knowledge of preventive sexual practices related to HIV and AIDS. It is necessary to implement an indicator of knowledge that allows for the creation and monitoring of sexual education programmes.

  19. A project in Zambia: talking to children about AIDS.

    1988-09-01

    Early in 1987, it became clear to this individual that children were a high priority group for Acquired Immune Deficiency Syndrome (AIDS) education. Preparation for providing AIDS education in Zambia included reading as much as possible about AIDS and AIDS education in schools, contacting the Health Education Unit at the Ministry of Health for their permission and advice, and making posters and preparing a list of 10 basic questions about AIDS. The 1st talks were at a boys' technical school and a large girls' day school. Following an introduction of the subject, the format included: a 10-minute quiz with students writing down their answers; a 35-40 minute talk, using posters as visual aids; a 20-30 minute open question time; and a repeat of the same quiz as a form of "posttest." The students responded positively, and there was a substantial increase in the percentage of correct answers after each talk. Subsequently, talks were given in other Lusaka secondary schools. After the 1st few talks, the pretest and posttest was discontinued as it was considered preferable to spend more time answering the students' questions. The talks varied depending on the audience, but posters were always included as visual aids. Initially, this AIDS education effort was voluntary and unfunded. Subsequently, and as the work grew, NORAD funded the project, paying for duplicating and printing as well as a salary on an hourly basis. A booklet on AIDS for secondary schools has been written and duplicated and accepted by the Intersectorial Committee on AIDS Health Education with minor changes. Late in 1987, the booklet was rewritten totally and expanded, with numerous illustrations. Throughout the booklet, human immunodeficiency virus (HIV) is carefully differentiated from AIDS disease. Talks also have been initiated at the Upper Primary School level. The format has been altered somewhat for these younger children as they tend to be noisy and excited.

    Eight groundwater observation wells were installed along the river plain, where the landscapes varied from floodplain, to oasis farmland, to desert-oasis ecotone to desert, in a typical desert-oasis ecotone in northwestern China. Ten years of data were used to analyze temporal and spatial changes in the groundwater depth. The results indicated that in the last decade: (1) the groundwater depths in the floodplain (GW1) and the desert (GW8) were basically stable; (2) the groundwater depths in the oasis farmland (GW2, GW3, GW4) increased dramatically: the annual fluctuations were 1.43, 1.01 and 0.79 m respectively, with the groundwater depths increasing by 0.13-0.18 m every year; (3) the groundwater depths in the desert-oasis ecotone (GW5, GW6, GW7) also increased dramatically: the annual fluctuations were 1.10, 1.06 and 1.05 m respectively, and the depths increased by 0.10-0.15 m every year; (4) the influence distance between the river and both the farmland and the desert-oasis ecotone was about 1000-2000 m in the study area. These results show that the natural seasonal fluctuation influence on groundwater depths was not significant, but the human-induced fluctuations such as intensive irrigation caused a significant increase in groundwater depth in both the farmland and the desert-oasis ecotone, seriously affecting sustainable agriculture development and the environment, in the oasis.

    Although the social, economic, and political dimensions of the HIV/AIDS epidemic have been studied in considerable depth, the relationship between HIV/AIDS and its environmental causes and consequences remains largely unexplored. We reviewed the evidence of interactions between ecosystem health and the HIV/AIDS pandemic. We hypothesized a syndemic between environmental degradation and HIV/AIDS; they exhibit bidirectional, self-reinforcing interactions. We have presented a syndemic framework detailing multiple synergistic relationships. This framework hinges on the vulnerability of populations as the linchpin between the pandemic and environmental health. A coherent research and practice agenda for addressing the syndemic that focuses on the 2 issues as not only concurrent but also intertwined phenomena is urgently needed. PMID:23237167

    Given the well documented undesired impacts of HIV/AIDS globally, there is a need to create a statistical inventory of research output on HIV/AIDS. This need is particularly important for a country such as Lesotho, whose HIV/AIDS prevalence is one of the highest globally. Research on HIV/AIDS in sub-Saharan Africa continues to trail behind that of other regions, especially those of the developed countries. Lesotho, a sub-Saharan country, is a developing country with lower research output in this area when longitudinally compared to other countries. This study reviewed the volume and scope of the general research output on HIV/AIDS in Lesotho and assessed the coverage of the national research agenda on HIV/AIDS, making recourse to statistical principles. A bibliometric review of studies on HIV/AIDS retrieved from the SCOPUS and PubMed databases, published within the 30-year period between 1985 and 2016, was conducted. The focus of each of the studies was analysed and the studies were cross-matched with the national research agenda in accordance with bibliometric methodologies. In total, 1280 studies comprising 1181 (92.3%) journal articles, 91 (7.1%) books and 8 (0.6%) conference proceedings were retrieved. By proportion, estimation of burden of infection (40.7%) had the highest research volume, while basic (5.5%) and preventive measures (24.4%) and national planning (29.4%) had the lowest. Out of the total studies retrieved, only 516 (40.3%) matched the national research agenda. Research on maternal and child health quality of care, viral load point-of-care devices, and infant point-of-care diagnosis had hardly any publications in the high priority research category of the agenda. Notwithstanding a considerable research output on HIV/AIDS for Lesotho, there is insufficient coverage of the national research agenda in this research area. The major research gaps on general research output are in basic and preventive measures as well as national planning. There is also

    Objective To explore the impact of HIV/AIDS on maternity care providers (MCP) in labor and delivery in a high HIV prevalence setting in sub-Saharan Africa. Design Qualitative one-on-one in-depth interviews with MCPs. Setting Four health facilities providing labor and delivery services (2 public hospitals, a public health center, and a small private maternity hospital) in Kisumu, Nyanza Province, Kenya. Participants Eighteen (18) MCPs, including 14 nurse/midwives, 2 physician assistants, and 2 physicians (ob/gyn specialists). Results The HIV/AIDS epidemic has had numerous adverse effects and a few positive effects on MCPs in this setting. Adverse effects include reductions in the number of health care providers, increased workload, burnout, reduced availability of services in small health facilities when workers are absent due to attending HIV/AIDS training programs, difficulties with confidentiality and unwanted disclosure, and MCPs' fears of becoming HIV infected and the resulting stigma and discrimination. Positive effects include improved infection control procedures on maternity wards and enhanced MCP knowledge and skills. Conclusion A multi-faceted package including policy, infrastructure, and training interventions is needed to support MCPs in these settings and ensure that they are able to perform their critical roles in maternal healthcare and prevention of HIV/AIDS transmission.

    This study assessed (a) the impact of a technology-aided programme on the leisure and communication engagement of persons with advanced amyotrophic lateral sclerosis (ALS) and (b) the opinion of rehabilitation and care personnel regarding the programme. The programme's impact was assessed with four participants who were allowed to activate leisure and communication options through basic responses (e.g. knee, finger or lip movements) and microswitches. Forty-two care and health professionals rated the programme after watching video clips of persons with ALS (three of the four involved in this study and three involved in previous studies) during and outside of the programme. The programme was effective with all participants. Their mean percentages of session time with independently initiated leisure and communication engagements were zero during baseline and increased to between nearly 70 and 80 during the intervention. The care and health professionals rated the technology-aided programme as beneficial for the participants' positive engagement and social image, fairly practical for daily contexts and interesting from a personal standpoint. The programme might be viewed as a viable resource for persons with advanced ALS. Implications for Rehabilitation A programme characterised by versatility, simplicity and relatively low cost could be considered practically relevant for persons with ALS and their contexts. A programme that is effective in fostering participants' independent leisure and communication engagement and is positively rated by care and rehabilitation personnel is more likely to be accepted and used with consistency. Any programme directed at persons affected by ALS needs to be adapted to the persons' progressive deterioration, starting from the response and microswitch used for accessing the programme's options.

  9. Chemical composition of selected Kansas brines as an aid to interpreting change in water chemistry with depth

    USGS Publications Warehouse

    Dingman, R.J.; Angino, E.E.

    1969-01-01

    Chemical analyses of approximately 1,881 samples of water from selected Kansas brines define the variations of water chemistry with depth and aquifer age. The most concentrated brines are found in the Permian rocks which occupy the intermediate section of the geologic column of this area. Salinity decreases below the Permian until the Ordovician (Arbuckle) horizon is reached and then increases until the Precambrian basement rocks are reached. Chemically, the petroleum brines studied in this small area fit the generally accepted pattern of an increase in calcium, sodium and chloride content with increasing salinity. They do not fit the often-predicted trend of increases in the calcium to chloride ratio, calcium content and salinity with depth and geologic age. The calcium to chloride ratio tends to be asymptotic to about 0.2 with increasing chloride content. Sulfate tends to decrease with increasing calcium content. Bicarbonate content is relatively constant with depth. If many of the hypotheses concerning the chemistry of petroleum brines are valid, then the brines studied are anomolous. An alternative lies in accepting the thesis that exceptions to these hypotheses are rapidly becoming the rule and that indeed we still do not have a valid and general hypothesis to explain the origin and chemistry of petroleum brines. ?? 1969.

    The study aims to investigate the cognition degree and influencing factors of first aid knowledge among dentists in Sichuan province, and to provide suggestions for the training of oral clinician. A questionnaire was designed for this study. It included the basic situation of population, first aid knowledge level, emergency situation often encountered in stomatology clinic, first aid training situation, learning approach and attitude of first aid knowledge, etc. This questionnaire was used to investigate the dentists of medical institutions in various cities in Sichuan province. The survey results was statistical analyzed. There were 245 valid questionnaires. 1) The level of first aid knowledge of dentists was generally lower in Sichuan province. Work department and other departments work experience were the influencing factors of knowledge level of first aid knowledge among dentists. 2) 87.3% of dentists believed that it was very necessary to master the knowledge of first aid, but in the event of an emergency situation, 73.5% of dentists only can find other doctors to guide themselves to help. 3) The most common way to learn first aid knowledge was through work experience and medical school's first aid course. Dentists should strengthen the learning and training to improve the first aid skill.

    The Global Fund to Fight AIDS, Tuberculosis and Malaria was created to greatly expand access to basic services to address the three diseases in its name. From its beginnings, its governance embodied some human rights principles: civil society is represented on its board, and the country coordination mechanisms that oversee funding requests to the Global Fund include representatives of people affected by the diseases. The Global Fund's core strategies recognize that the health services it supports would not be effective or cost-effective without efforts to reduce human rights-related barriers to access and utilization of health services, particularly those faced by socially marginalized and criminalized persons. Basic human rights elements were written into Global Fund grant agreements, and various technical support measures encouraged the inclusion in funding requests of programs to reduce human rights-related barriers. A five-year initiative to provide intensive technical and financial support for the scaling up of programs to reduce these barriers in 20 countries is ongoing.

  13. Facing the challenge: household responses to HIV/AIDS in Mumbai, India.

    Bharat, S; Aggleton, P

    1999-02-01

    How households and families respond to AIDS is of fundamental importance when it comes to designing programmes and interventions to provide support and care to people living with HIV disease. Where household and family responses are negative, different kinds of interventions may be needed from those where responses are more supportive. This paper reports on findings from an in-depth study of household and family responses to HIV and AIDS in India. Using individual and couple interviews, data were collected on the ways in which care and support were offered (or denied) to people living with HIV and AIDS. Findings show that responses are greatly influenced by prevailing gender relations, with men being responded to more positively than women, as well as other variables such as social status. The quality of responses is also influenced by pre-existing patterns of support and discord within the family. Where trust is high and spousal conflict slight, for example, HIV and AIDS are reacted to more positively than when there is mistrust and inter-spousal conflict. Suggestions are made concerning programme and intervention development so as to strengthen existing responses, and to maximize the success of home-based care.

    2015-01-01

    This study examines facial tissue depth in Canadian Mi'kmaq adults. Using ultrasound, measurements were taken at 19 landmarks on the faces of 152 individuals aged 18-75 years old. The relationships between tissue thickness, age, and sex were investigated. A positive linear trend exists between tissue thickness and age for Mi'kmaq males and females at multiple landmarks. Seven landmarks show significant differences in facial tissue depth between males and females aged 18-34 years old; no landmarks show significant differences in facial tissue depth between males and females aged 35-45 years old and 46-55 years old. Significant differences were shown in facial tissue depth between Mi'kmaq and White Americans and Mi'kmaq and African Americans. These data can assist in 3-D facial reconstructions and aid in establishing the identity of unknown Mi'kmaq individuals. Copyright © 2014 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

  15. Health and human rights in today’s fight against HIV/AIDS

    PubMed Central

    Stemple, Lara

    2012-01-01

    The development of the health and human rights framework coincided with the beginning of the rapid spread of HIV/AIDS. Since then, the international community has increasingly turned to human rights language and instruments to address the disease. Not only are human rights essential to addressing a disease that impacts marginalized groups most severely, but the spread of HIV/AIDS itself exacerbates inequality and impedes the realization of a range of human rights. Policy developments of the past decade include the United Nations (UN) Committee on Economic, Social and Cultural Rights’ General Comment on the ‘Right to Health’, the UN Declaration of Commitment on HIV/AIDS, and the UN’s International Guidelines on HIV/AIDS and Human Rights, among others. Rights-related setbacks include the failure of the Declaration and its 5-year follow-up specifically to address men who have sex with men, sex workers, and intravenous drug users, political restrictions placed on urgently needed US President’s Emergency Plan for AIDS Relief (PEPFAR) funds, and the failure of many countries to decriminalize same-sex sex and outlaw discrimination against people living with HIV/AIDS. Male circumcision as an HIV prevention measure is a topic around which important debate, touching on gender, informed consent and children’s rights, serves to illustrate the ongoing vitality of the health and human rights dialogue. Mechanisms to increase state accountability for addressing HIV/AIDS should be explored in greater depth. Such measures might include an increase in the use of treaty-based judicial mechanisms, the linking of human rights compliance with preferential trade agreements, and rights requirements tied to HIV/ AIDS funding.

  18. Beyond the political model of reporting: nonspecific symptoms in media communication about AIDS.

    PubMed

    Check, W A

    1987-01-01

    Mass media have functioned well in transmitting much of the basic information about the AIDS epidemic; however, media coverage of AIDS has been flawed. In many ways these flaws have resulted from the limitations and conventions of traditional journalism, especially the need to appeal to a large mainstream audience and a reliance on authorities as sources and validators of information. News stories typically rely on a single articulate authority, and articles that involve conspiracy or controversy or have a high entertainment value are favored. Although coverage of politics and social issues is not distorted by these journalistic conventions, coverage of science suffers. Analysis of news coverage of AIDS shows that mass media often respond to sensationalism rather than to important scientific developments. In addition, scientific disagreements are better adjudicated by evidence than by appeals to authority. As a result, media coverage often obscures the process of scientific deliberation. Public health officials need to consider setting up a special channel of communications to clarify information about AIDS.

    The primary purpose of government provided student financial aid is to increase college access by bringing the out-of-pocket price of attendance within reach of more students. The basic idea is quite straightforward. If a good or service costs $100 to buy and the government gives consumers a $50 subsidy, then consumers need only spend $50 of their…

  20. VISIDEP™: visual image depth enhancement by parallax induction

    NASA Astrophysics Data System (ADS)

    Jones, Edwin R.; McLaurin, A. P.; Cathey, LeConte

    1984-05-01

    The usual descriptions of depth perception have traditionally required the simultaneous presentation of disparate views presented to separate eyes with the concomitant demand that the resulting binocular parallax be horizontally aligned. Our work suggests that the visual input information is compared in a short-term memory buffer which permits the brain to compute depth as it is normally perceived. However, the mechanism utilized is also capable of receiving and processing the stereographic information even when it is received monocularly or when identical inputs are simultaneously fed to both eyes. We have also found that the restriction to horizontally displaced images is not a necessary requirement and that improvement in image acceptability is achieved by the use of vertical parallax. Use of these ideas permit the presentation of three-dimensional scenes on flat screens in full color without the encumbrance of glasses or other viewing aids.

    2007-01-01

    This study examined HIV/AIDS knowledge and beliefs in Haitian adolescents in an HIV epicenter, Miami-Dade Florida. This study examined survey data from 300 Haitian adolescents, aged 13 through 18, from both low-and middle-income neighborhoods. A sub-sample of 80 adolescents was selected for in-depth interviews and continuous observations with their families and networks of friends, which added rich descriptions to the quantitative data. Overall knowledge about HIV/AIDS was high with the majority of adolescents identifying unprotected sex and sharing injection drug needles as HIV transmission routes. Moreover, approximately 75% of the adolescents reported condom use as an effective preventive strategy. However, misconceptions that could reduce adolescents' adoption of HIV preventive strategies were also identified. The adolescents' sources for information about HIV/AIDS as well as implications for prevention interventions are discussed. PMID:17502921

    This study uses Goffman's [1963. Stigma: Notes on the Management of Spoiled Identity, New Jersey, Prentice-Hall] theory of stigma as an intellectual scaffold to help understand the social meaning of HIV/AIDS stigma from People Living with HIV/AIDS. The study adopts a qualitative approach because of its appropriateness for unravelling subjective phenomena such as the experiences of HIV/AIDS stigma. In-depth interviews were conducted with 10 HIV-positive employees of a retailing company located in the Western Cape province of South Africa who volunteered to participate in the study. The participants with the discreditable stigma internalised society's prejudice towards those living with the virus. As a result, the participants relied on self-isolation and social withdrawal to cope with enacted stigma. Managing information about one's status and deciding whether, who, when, etc., to tell are crucial questions. The participants feared being devalued by family, friends, co-workers and the community. In concurrence with Goffman [1963], the HIV/AIDS stigma is seen as about relationships.

    2017-07-01

    The influence of preferential sputtering on depth resolution of sputter depth profiles is studied for different sputtering rates of the two components at an A/B interface. Surface concentration and intensity depth profiles on both the sputtering time scale (as measured) and the depth scale are obtained by calculations with an extended Mixing-Roughness-Information depth (MRI)-model. The results show a clear difference for the two extreme cases (a) preponderant roughness and (b) preponderant atomic mixing. In case (a), the interface width on the time scale (Δt(16-84%)) increases with preferential sputtering if the faster sputtering component is on top of the slower sputtering component, but the true resolution on the depth scale (Δz(16-84%)) stays constant. In case (b), the interface width on the time scale stays constant but the true resolution on the depth scale varies with preferential sputtering. For similar order of magnitude of the atomic mixing and the roughness parameters, a transition state between the two extremes is obtained. While the normalized intensity profile of SIMS represents that of the surface concentration, an additional broadening effect is encountered in XPS or AES by the influence of the mean electron escape depth which may even cause an additional matrix effect at the interface.

    The objective of this study is to identify the need for basic first aid knowledge and skills among adolescents. A cross-sectional study using multistage sampling was conducted among 375 secondary school students in Kuantan, Pahang, Malaysia. The survey was adapted from a Hong Kong Red Cross survey. A back to back translation of this instrument was carried out by two bilingual medical experts with Cronbach's alpha 0.8. The data were analyzed using SPSS (Statistical Package for the Social Sciences) in terms of descriptive analysis, and an independent t-test and chi-square test were carried out. There were 149 respondents from the lower form (grade level) and 226 respondents from the upper form. The majority of respondents (81.6%) were Malay. An independent t-test revealed a significant association between knowledge and attitude, as students who scored higher on first aid questions showed a more positive attitude towards first aid (1.475%). There were also significant associations between race and experience learning first aid. Adolescents receive minimal first aid education. Thus, there is an urgent need to educate adolescents more in first aid to promote a safer community and to prevent any further injuries. Copyright © 2018 Elsevier España, S.L.U. All rights reserved.

  14. Expansive Soil Crack Depth under Cumulative Damage

    PubMed Central

    Shi, Bei-xiao; Chen, Sheng-shui; Han, Hua-qiang; Zheng, Cheng-feng

    2014-01-01

    The crack developing depth is a key problem to slope stability of the expansive soil and its project governance and the crack appears under the roles of dry-wet cycle and gradually develops. It is believed from the analysis that, because of its own cohesion, the expansive soil will have a certain amount of deformation under pulling stress but without cracks. The soil body will crack only when the deformation exceeds the ultimate tensile strain that causes cracks. And it is also believed that, due to the combined effect of various environmental factors, particularly changes of the internal water content, the inherent basic physical properties of expansive soil are weakened, and irreversible cumulative damages are eventually formed, resulting in the development of expansive soil cracks in depth. Starting from the perspective of volumetric strain that is caused by water loss, considering the influences of water loss rate and dry-wet cycle on crack developing depth, the crack developing depth calculation model which considers the water loss rate and the cumulative damages is established. Both the proposal of water loss rate and the application of cumulative damage theory to the expansive soil crack development problems try to avoid difficulties in matrix suction measurement, which will surely play a good role in promoting and improving the research of unsaturated expansive soil.

    Hirschmann, A; Arathoon, E; Lundgren, R; Bezmalinovic, B

    1992-01-01

    Despite the mistaken belief in Central America that AIDS is primarily a disease of male homosexuals, some 21% of reported cases in Guatemala have been women 15-44 years old. Many Guatemalan women are at risk of AIDS and other sexually transmitted diseases (STDs) because of their lack of sexual bargaining power and negotiating skills, the widespread acceptance of male infidelity in marriage, tolerance of bisexual relations and frequenting of prostitutes, and ignorance of women about sexuality. Condom use is infrequent in Guatemala. Most men and women lack knowledge of AIDS and other STDs and have no perception of their own vulnerability. Male alcohol use and violence against women diminishes the ability of women to protect themselves. Sex education and information about STDs should be provided for both men and women to slow the spread of AIDS. AIDS educators should direct their messages to women toward promoting condom use, increasing knowledge of AIDS and STDs, providing basic sex education, questioning stereotypes of AIDS patients as persons with disordered lifestyles, encouraging realistic assessment of risks, and assisting women to increase their negotiating ability in sexual relations. Three crucial ways of helping women protect themselves are by making them aware of the influence of gender roles in their reproductive lives, teaching them communication and negotiating skills, and providing strategies for them to confront alcohol abuse and gender violence. Survey results indicate that Guatemalan women were extremely motivated to protect their children and secondarily to maintain their homes and be good wives. Motivational messages for AIDS prevention should be related to children and the family. Men were found to be concerned about their families as well and to fear the stigma of HIV infection. Educational techniques for AIDS prevention should be accessible to the illiterate and should focus on life stories or similar methods that make AIDS seem less abstract to

    1995-06-01

    The main purpose of this study was to gain information on the knowledge that people living in squatter conditions have about AIDS, their attitude towards this disease and their sexual practices. The study had two parts, in-depth interviews and a survey. The in-depth interviews were held with 68 male informal settlement dwellers to obtain information on the type of questions to ask in the quantitative part of the study, taking into account the sensitivity of the information we were seeking, and how best to phrase these questions. For the survey, the 300 male informal settlement residents who were interviewed, were located by means of systematic sampling techniques. The results of the survey showed that most of the respondents were living in squalid conditions, without recreation facilities. They were also likely to have had more than one partner (54%). Most of the respondents (90%) had heard about AIDS as a disease. Even though they were aware of AIDS as an epidemic in the country as a whole, they were not convinced that the disease exists in their community, the main reason being that they have never heard about nor seen a person with AIDS in the township. There is an urgent need for AIDS education. But this education cannot take place as a separate activity from other upliftment activities in squatter areas.

    2009-06-01

    Individual in-depth interviews were conducted with 47 children (ages 8-17 years) experiencing the loss of one or both parents due to HIV/AIDS in two rural counties of central China. Findings in this study reveal that the families of the children orphaned by AIDS had experienced financial burdens because of treatment costs for sick parents and loss of labor in the household. The majority of the participants reported some level of stigmatization because of their parents' HIV status. The participants described feelings of sadness, fear, anxiety, anger, loneliness, low self-esteem, social withdrawal, and sleep problems. Implications for intervention programs include the need for psychological support and special counseling services, more public education with accurate knowledge about HIV/AIDS to decrease stigma and discrimination, and financial programs to decrease economic and caregiving burdens for these children.

    We aimed to evaluate knowledge of first aid among new undergraduates and whether it is affected by their chosen course. A questionnaire was developed to assess knowledge of how to activate the Mobile Emergency Attendance Service - MEAS (Serviço de Atendimento Móvel de Urgência; SAMU), recognize a pre-hospital emergency situation and the first aid required for cardiac arrest. The students were also asked about enrolling in a first aid course. Responses were received from 1038 of 1365 (76.04%) new undergraduates. The questionnaires were completed in a 2-week period 1 month after the beginning of classes. Of the 1038 respondents (59.5% studying biological sciences, 11.6% physical sciences, and 28.6% humanities), 58.5% knew how to activate the MEAS/SAMU (54.3% non-biological vs 61.4% biological, P=0.02), with an odds ratio (OR)=1.39 (95%CI=1.07-1.81) regardless of age, sex, origin, having a previous degree or having a relative with cardiac disease. The majority could distinguish emergency from non-emergency situations. When faced with a possible cardiac arrest, 17.7% of the students would perform chest compressions (15.5% non-biological vs 19.1% biological first-year university students, P=0.16) and 65.2% would enroll in a first aid course (51.1% non-biological vs 74.7% biological, P<0.01), with an OR=2.61 (95%CI=1.98-3.44) adjusted for the same confounders. Even though a high percentage of the students recognized emergency situations, a significant proportion did not know the MEAS/SAMU number and only a minority had sufficient basic life support skills to help with cardiac arrest. A significant proportion would not enroll in a first aid course. Biological first-year university students were more prone to enroll in a basic life support course.

  1. Role of nanotechnology in HIV/AIDS vaccine development.

    PubMed

    Liu, Ying; Chen, Chunying

    2016-08-01

    HIV/AIDS is one of the worst crises affecting global health and influencing economic development and social stability. Preventing and treating HIV infection is a crucial task. However, there is still no effective HIV vaccine for clinical application. Nanotechnology has the potential to solve the problems associated with traditional HIV vaccines. At present, various nano-architectures and nanomaterials can function as potential HIV vaccine carriers or adjuvants, including inorganic nanomaterials, liposomes, micelles and polymer nanomaterials. In this review, we summarize the current progress in the use of nanotechnology for the development of an HIV/AIDS vaccine and discuss its potential to greatly improve the solubility, permeability, stability and pharmacokinetics of HIV vaccines. Although nanotechnology holds great promise for applications in HIV/AIDS vaccines, there are still many inadequacies that result in a variety of risks and challenges. The potential hazards to the human body and environment associated with some nano-carriers, and their underlying mechanisms require in-depth study. Non-toxic or low-toxic nanomaterials with adjuvant activity have been identified. However, studying the confluence of factors that affect the adjuvant activity of nanomaterials may be more important for the optimization of the dosage and immunization strategy and investigations into the exact mechanism of action. Moreover, there are no uniform standards for investigations of nanomaterials as potential vaccine adjuvants. These limitations make it harder to analyze and deduce rules from the existing data. Developing vaccine nano-carriers or adjuvants with high benefit-cost ratios is important to ensure their broad usage. Despite some shortcomings, nanomaterials have great potential and application prospects in the fields of AIDS treatment and prevention. Copyright © 2016 Elsevier B.V. All rights reserved.

    Colorectal cancer is the fourth leading cause of cancer deaths worldwide. The detection and removal of premalignant lesions through an endoscopic colonoscopy is the most effective way to reduce colorectal cancer mortality. Unfortunately, conventional colonoscopy has an almost 25% polyp miss rate, in part due to the lack of depth information and contrast of the surface of the colon. Estimating depth using conventional hardware and software methods is challenging in endoscopy due to limited endoscope size and deformable mucosa. In this work, we use a joint deep learning and graphical model-based framework for depth estimation from endoscopy images. Since depth is an inherently continuous property of an object, it can easily be posed as a continuous graphical learning problem. Unlike previous approaches, this method does not require hand-crafted features. Large amounts of augmented data are required to train such a framework. Since there is limited availability of colonoscopy images with ground-truth depth maps and colon texture is highly patient-specific, we generated training images using a synthetic, texture-free colon phantom to train our models. Initial results show that our system can estimate depths for phantom test data with a relative error of 0.164. The resulting depth maps could prove valuable for 3D reconstruction and automated Computer Aided Detection (CAD) to assist in identifying lesions.

    2013-01-01

    Background Considering the significant impact of school-based HIV/AIDS education, in 2007, a curriculum on HIV/AIDS was incorporated in the national curriculum for high school students of Bangladesh through the Government’s HIV-prevention program. Based on the curriculum, an intervention was designed to train teachers responsible for teaching HIV/AIDS in classes. Methods In-depth interviews were conducted with teachers to understand their ability, skills, and confidence in conducting HIV/AIDS classes. Focus-group discussions (FGDs) were conducted with students who participated in HIV/AIDS classes. HIV/AIDS classes were also observed in randomly-selected schools. Thematic assessment was made to analyze data. Results The findings showed that the trained teachers were more comfortable in using interactive teaching methods and in explaining sensitive issues to their students in HIV/AIDS classes. They were also competent in using interactive teaching methods and could ensure the participation of students in HIV/AIDS classes. Conclusions The findings suggest that cascading training may be scaled up as it helped increase ability, skills, and confidence of teachers to successfully conduct HIV/AIDS classes. PMID:24144065

  6. Global Health Initiatives and aid effectiveness: insights from a Ugandan case study

    2011-01-01

    Background The emergence of Global Health Initiatives (GHIs) has been a major feature of the aid environment of the last decade. This paper seeks to examine in depth the behaviour of two prominent GHIs in the early stages of their operation in Uganda as well as the responses of the government. Methods The study adopted a qualitative and case study approach to investigate the governance of aid transactions in Uganda. Data sources included documentary review, in-depth and semi-structured interviews and observation of meetings. Agency theory guided the conceptual framework of the study. Results The Ugandan government had a stated preference for donor funding to be channelled through the general or sectoral budgets. Despite this preference, two large GHIs opted to allocate resources and deliver activities through projects with a disease-specific approach. The mixed motives of contributor country governments, recipient country governments and GHI executives produced incentive regimes in conflict between different aid mechanisms. Conclusion Notwithstanding attempts to align and harmonize donor activities, the interests and motives of the various actors (GHIs and different parts of the government) undermine such efforts.

  7. Keeping a tight grip on the reins: donor control over aid coordination and management in Bangladesh.

    A long-standing consensus that aid coordination should be owned by recipient authorities has been eclipsed by accord on the desirability of recipient management of aid along-side domestic resources. Nonetheless, in many low and lower-middle income countries, donors remain remarkably uncoordinated; where attempts at coordination are made, they are often donor-driven, and only a small proportion of aid is directly managed by recipients. This paper draws on evidence from an in-depth review of aid to the health sector in Bangladesh to analyze the systems by which external resources are managed. Based on interviews with key stakeholders, a questionnaire survey and analysis of documentary sources, the factors constraining the government from assuming a more active role in aid management are explored. The results suggest that donor perceptions of weak government capacity, inadequate accountability and compromised integrity only partially account for the propensity for donor leadership. Equally important is the consideration that aid coordination has a markedly political dimension. Stakeholders are well aware of the power, influence and leverage which aid coordination confers, an awareness which colours the desire of some stakeholders to lead aid coordination processes, and conditions the extent and manner by which others wish to be involved. It is argued that recipient management of external aid is dependent on major changes in the attitudes and behaviours of recipients and donors alike.

    To analyze the genesis of the policy for controlling AIDS in Brazil. Socio-historical study (1981-1989), based on Bordieu's genetic sociology, by document analysis, bibliographical review, and in-depth interviews. It consisted of a connection between the analysis of the paths of 33 agents involved in the creation of a social space focusing on AIDS-related issues and the historical possibility conditions of the drafting of a specific policy. AIDS Space is a gathering point for the paths of agents from several social fields (medical, scientific, political, and bureaucratic fields). A specific space for relationships, which enabled the drafting of a policy for controlling the AIDS epidemic, but also a place where the authority to talk about the meaning of the disease, the methods to prevent and treat it was under dispute. The analysis showed how the various structures (democratic administrations in Sao Paulo and at the national level, with public health officers taking important positions) and the lack of a specific therapy contributed to social agents of different ranks and backgrounds to initially set prevention as a priority. The rise of the sanitary movement, the organization of SUS, and the dominance of the medical field at the AIDS Space contributed to foster treatment as a part of the measures to control the epidemic. These conditions allowed drafting a policy based on the integrality of care, by linking prevention and treatment in the following decade, with important participation from state bureaucracy and researchers.

    Aim To assess Turkish school teachers’ knowledge, attitudes, and misconceptions of HIV/AIDS. Methods This cross-sectional descriptive study was conducted in Sivas, Middle Anatolian province of Turkey, from January to May 2009. We selected and interviewed 898 teachers using a simple systematic sampling method. Results All respondents heard about AIDS. Most knew that it could be transmitted by infected blood (98.0%) and sexual contact (93.4%) and some (33.2%) thought that it could be transmitted by mosquitoes. Although the majority of them strongly agreed or agreed with the statement that “people with AIDS should be helped, supported and treated” (98.0%), about 40% and 70% of them, respectively, agreed or strongly agreed with the statement that infected people should be quarantined. Young teachers with a higher level of knowledge about HIV/AIDS had more positive attitudes. Conclusion This study provided basic information on school teachers’ AIDS knowledge and attitudes and showed that various misconceptions of HIV transmission were a matter of concern. A considerable number of respondents with undesirable attitudes toward HIV/AIDS indicates the need for education of teachers on the subject. PMID:22661141

  14. Qualitative to quantitative: linked trajectory of method triangulation in a study on HIV/AIDS in Goa, India.

    With 3.1 million people estimated to be living with HIV/AIDS in India and 39.5 million people globally, the epidemic has posed academics the challenge of identifying behaviours and their underlying beliefs in the effort to reduce the risk of HIV transmission. The Health Belief Model (HBM) is frequently used to identify risk behaviours and adherence behaviour in the field of HIV/AIDS. Risk behaviour studies that apply HBM have been largely quantitative and use of qualitative methodology is rare. The marriage of qualitative and quantitative methods has never been easy. The challenge is in triangulating the methods. Method triangulation has been largely used to combine insights from the qualitative and quantitative methods but not to link both the methods. In this paper we suggest a linked trajectory of method triangulation (LTMT). The linked trajectory aims to first gather individual level information through in-depth interviews and then to present the information as vignettes in focus group discussions. We thus validate information obtained from in-depth interviews and gather emic concepts that arise from the interaction. We thus capture both the interpretation and the interaction angles of the qualitative method. Further, using the qualitative information gained, a survey is designed. In doing so, the survey questions are grounded and contextualized. We employed this linked trajectory of method triangulation in a study on the risk assessment of HIV/AIDS among migrant and mobile men. Fieldwork was carried out in Goa, India. Data come from two waves of studies, first an explorative qualitative study (2003), second a larger study (2004-2005), including in-depth interviews (25), focus group discussions (21) and a survey (n=1259). By employing the qualitative to quantitative LTMT we can not only contextualize the existing concepts of the HBM, but also validate new concepts and identify new risk groups.

    Estimates show that by 2010 up to six million South Africans will be HIV-infected. Simultaneously, public health care resources are overstretched and communities and families are taking more responsibility for providing care. However, little work in South Africa has investigated the possible psychosocial impacts on caregivers. This study investigates psychosocial impacts at household level with reference to gender, programme, and policy implications. Forty-five in-depth interviews were held with primary caregivers of people living with AIDS (PWA). Participants were recruited using purposive and snowball sampling. Forty-three respondents were women, signifying that gender is an important issue in this context. Data were analysed using a grounded theory approach. Care giving placed considerable demands on caregivers, which was exacerbated by insufficient support, dire poverty and the added responsibilities of caring for other household members. Lack of basic resources was common and chronic, and care giving impacted negatively on employment and social life. Stigma and prejudice towards caregivers was common and exacerbated stress levels. Assessment of support received from various sources ranged widely. The lack of support was often debilitating. Respondents who felt supported linked this support to improved psychosocial status. Recommendations for policy on home-based care are outlined.

  16. Securitizing HIV/AIDS: a game changer in state-societal relations in China?

    PubMed

    Lo, Catherine Yuk-Ping

    2018-05-16

    China has experienced unprecedented economic growth since the 1980s. Despite this impressive economic development, this growth exists side by side with the human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and severe acute respiratory syndrome (SARS) crises and the persisting deficiencies in public health provision in China. Acknowledging the prevailing health problems, the Chinese government has encouraged the development of health non-governmental organizations (NGOs) to respond to the health challenges and address the gaps in public health provision of the government. HIV/AIDS-focused NGOs have been perceived as the most outstanding civil society group developed in China. Considering the low priority of health policies since the economic reform, the limitation of the "third sector" activity permitted in authoritarian China, together with the political sensitivity of the HIV/AIDS problem in the country, this article aims to explain the proliferation of HIV/AIDS-focused NGOs in China with the usage of the securitization framework in the field of international relations (IR). The research that underpins this article is based on a desk-based literature review as well as in-depth field interviews with individuals working in HIV/AIDS-focused NGOs in China. Face-to-face interviews for this research were conducted between January and May in 2011, and between December 2016 and January 2017, in China. Discourse analysis was in particular employed in the study of the security-threat framing process (securitization) of HIV/AIDS in China. This article argues that the proliferation of HIV/AIDS-related NGOs in China is largely attributed to the normative and technical effects of HIV/AIDS securitization ushered in by the United Nations Security Council (UNSC) and supported by the Global Fund to Fight AIDS, Tuberculosis, and Malaria (hereinafter Global Fund) observed in China. Despite depicting a positive scenario, the development of HIV/AIDS

    Historically, basic scientists and clinical researchers have transduced reality into data so that they might explain or predict the world. Because data are fundamental to their craft, these investigators have been on the front lines of the Big Data deluge in recent years. Radiotherapy data are complex and longitudinal data sets are frequently collected to track both tumor and normal tissue response to therapy. As basic, translational and clinical investigators explore with increasingly greater depth the complexity of underlying disease processes and treatment outcomes, larger sample populations are required for research studies and greater quantities of data are being generated. In addition, well-curated research and trial data are being pooled in public data repositories to support large-scale analyses. Thus, the tremendous quantity of information produced in both basic and clinical research in radiation therapy can now be considered as having entered the realm of Big Data. PMID:26797542

The main objective of this study was to evaluate the predictive performance of vegetation indices and band depth analysis parameters for estimation of green biomass using MERIS data. Green biomass was best predicted by NBDI (normalized band depth index) and yielded a calibration R2 of 0.73 and an accuracy (independent validation dataset, n=30) of 136.2 g/m2 (47 % of the measured mean) compared to a much lower accuracy obtained by soil adjusted vegetation index SAVI (444.6 g/m2, 154 % of the mean) and by other vegetation indices. This study will contribute to map and monitor foliar biomass over the year at regional scale which intern can aid the understanding of bird migration pattern.

    The role of basic science education in a clinical setting remains unclear. Research to understand how academic clinicians perceive and use this part of their education can aid curricular development. To assess physician's attitudes toward the value of science knowledge in their clinical practice. Academic physicians from three medical schools completed a questionnaire about the utility of basic science education in core clinical tasks and in practice-based learning and improvement. A total of 109 clinical faculty returned the survey. Overall, 89% of the respondents indicated that basic science education is valuable to their clinical practice. When asked about the utility of basic science information in relation to direct patient care, greater than 50% of the doctors felt they use this when diagnosing and communicating with patients. This rose to greater than 60% when asked about choosing treatment options for their patients. Individuals also responded that basic science knowledge is valuable when developing evidence-based best practices. Specifically, 89% felt that they draw upon this information when training students/residents and 84% use this information when reading journal articles. This study shows that basic science education is perceived by responding academic physicians to be important to their clinical work.

    New researches are trying to integrate computer aided design (CAD) and computer aided manufacturing (CAM) environments. The role of process planning is to convert the design specification into manufacturing instructions. Setup planning has a basic role in computer aided process planning (CAPP) and significantly affects the overall cost and quality of machined part. This research focuses on the development for automatic generation of setups and finding the best setup plan in feasible condition. In order to computerize the setup planning process, three major steps are performed in the proposed system: a) Extraction of machining data of the part. b) Analyzing and generation of all possible setups c) Optimization to reach the best setup plan based on cost functions. Considering workshop resources such as machine tool, cutter and fixture, all feasible setups could be generated. Then the problem is adopted with technological constraints such as TAD (tool approach direction), tolerance relationship and feature precedence relationship to have a completely real and practical approach. The optimal setup plan is the result of applying the PSO (particle swarm optimization) algorithm into the system using cost functions. A real sample part is illustrated to demonstrate the performance and productivity of the system.

    directly at population level rather than in response to clinical interventions and testing and may be important in the uptake of the latter services. This communication response provides an important basis for HIV prevention if it is to be scaled to the population level. Vertical prevention (and even treatment) interventions need to engage more closely with local, horizontal communication and behavioural responses to AIDS. Communication programmes have to take root at the level of social networks working though local networks of meetings, chiefs, churches and health personnel as well as the media. Mobilising basic social communications may be a necessary resource (as much as services and finance) to scale HIV prevention and treatment to the population level.

    In the Congo, the first cases of AIDS were discovered in 1983 a Scientific Committee to Diagnose and Fight AIDS was established by the Ministry of HEALTH whose aim was to officially recognize AIDS in the Congo by: 1) evaluating the national situation, and 2) implementing a prevention program. In 1986 the Government purchased 2 ELISA diagnostic machines and established a blood bank. In 1987 the Government signed an agreement with the World Health Organization (WHO) to implement a short- term plan of action and the National Program Against AIDS was established and implemented with a national policy to prevent and control AIDS. In 1987 a National Symposium on AIDS took place and an IEC strategy developed. In 1988 the Triennial Plan Against AIDS was established for 1989-1991 with WHO to informal and educate people on AIDS, to prevent the HIV transmission through blood, to survey the progress of the epidemic and to treat those infected with HIV. In November 1988 the National Scientific Committee became the Scientific Commission of the national Committee Against AIDS presided over by the Minister of Health and Social Affairs with representation from all other sectors in the country. AIDS in the Congo is transmitted by HIV-1 through sex and blood (10-20%). Women and men alike have been affected representing all strata in society, however those affected are mostly from the urban areas. The seroprevalence in the urban areas is 5%, with 1% in the rural. 20% of those infected had blood transfusions 4-6 years before getting the HIV virus. Between 1983-1989 1940 cases of AIDS were reported to WHO; most of these were in the age group 20-4-. A KAP on AIDS was done showing that more than 90% of the population had head about AIDS: 65% knew about AIDS and 30% were using condoms. (author's modified).

  7. Understanding AIDS: historical interpretations and the limits of biomedical individualism.

    PubMed Central

    Fee, E; Krieger, N

    1993-01-01

    The popular and scientific understanding of acquired immunodeficiency syndrome (AIDS) in the United States has been shaped by successive historical constructions or paradigms of disease. In the first paradigm, AIDS was conceived of as a "gay plague," by analogy with the sudden, devastating epidemics of the past. In the second, AIDS was normalized as a chronic disease to be managed medically over the long term. By examining and extending critiques of both paradigms, it is possible to discern the emergence of an alternative paradigm of AIDS as a collective chronic infectious disease and persistent pandemic. Each of these constructions of AIDS incorporates distinct views of the etiology, prevention, pathology, and treatment of disease; each tacitly promotes different conceptions of the proper allocation of individual and social responsibility for AIDS. This paper focuses on individualistic vs collective, and biomedical vs social and historical, understandings of disease. It analyzes the use of individualism as methodology and as ideology, criticizes some basic assumptions of the biomedical model, and discusses alternative strategies for scientific research, health policy, and disease prevention.

    Analogical reasoning is central to all learning, whether in daily life situations, in the classroom or while doing research. Although analogies can aid the learning process of making sense of phenomena and understanding new ideas in terms of known ideas, these should be used with care. This article reports a study of the use of analogies and the consequences of this use in the teaching of magnetism with special reference to misconceptions. We begin by identifying concept confusion and associated misconceptions in magnetism due to in-service physics teachers’ spontaneous analogical reasoning. Two analogy-based experiments that can be used to convert such concept confusion to discernment are then described. These experiments focus on understanding basic principles about sources and interactions of magnetic fields and implement the constructivist learning processes of discrimination and generalization. Lastly, recommendations towards reinforcement of conceptual understanding of basic magnetism in its relation to electricity are proposed.

    Nowadays, there is a trend of HIV prevalence transmitting from high-risk group to average-risk group in China. Rural China is the weak link of HIV prevention, and rural areas of Henan province which is one of the most high-risk regions in China have more than 60% of the AIDS patients in the province. Thus, improving the HIV awareness and implementing health education become the top-priority of HIV/AIDS control and prevention. A multistage sampling was designed to draw 1129 people living with HIV/AIDS (PLWHAs) and 1168 non-PLWHAs in 4 prevalence counties of Henan province. A health promoting and social-psychological support model was constructed to improve the health knowledge of participants. Chi-square tests and unconditional logistic regression were performed to determine the intervention effect and influencing factors. All groups had misunderstandings towards the basic medical knowledge and the AIDS transmission mode. Before the intervention, 59.3% of the HIV/AIDS patients and 74.6% of the healthy people had negative attitudes towards the disease. There was statistically significant difference in the improvement of knowledge, attitude and action with regards to HIV prevention before and after intervention (P<0.05). PLWHAs who were males (OR=1.731) and had higher education level (OR=1.910) were found to have better HIV/AIDS health knowledge, whereas older PLWHAs (OR=0.961) were less likely to have better HIV/AIDS health knowledge. However, the intervention effect was associated with the expertise of doctors and supervisors, the content and methods of education, and participants' education level. It was concluded that health education of HIV/AIDS which positively influences the awareness and attitude of HIV prevention is popular in rural areas, therefore, a systematic and long-term program of HIV control and prevention is urgently needed in rural areas.

    2015-01-01

    Mental Health First Aid training is designed to equip people with the skills to help others who may be developing mental health problems or experiencing mental health crises. This training has consistently been shown to increase: (1) the recognition of mental health problems; (2) the extent to which course trainees' beliefs about treatment align with those of mental health professionals; (3) their intentions to help others; and (4) their confidence in their abilities to assist others. This paper presents a discussion of the potential role of Mental Health First Aid training in undergraduate mental health nursing education. Three databases (CINAHL, Medline, and PsycINFO) were searched to identify literature on Mental Health First Aid. Although Mental Health First Aid training has strong benefits, this first responder level of education is insufficient for nurses, from whom people expect to receive professional care. It is recommended that: (1) Mental Health First Aid training be made a prerequisite of preregistration nurse education, (2) registered nurses make a larger contribution to addressing the mental health needs of Australians requiring care, and (3) current registered nurses take responsibility for ensuring that they can provided basic mental health care, including undertaking training to rectify gaps in their knowledge.

    The purpose of this study was to understand the strategies employed by families that adopt Acquired Immune Deficiency Syndrome (AIDS)-orphaned children (Adoptive families) for coping with and mitigating the impact of AIDS in Mbeya Rural District, Tanzania. High numbers of AIDS-orphaned children aged below 18 years in Mbeya Region have led to increasing the burden of families caring for them. Understanding the coping strategies and impact mitigation activities employed by adoptive families is important in order to develop programmes to help them. This study employed a qualitative method for data collection (one-on-one in-depth interviews). The respondents included 12 male and 8 female heads of families that provide essential care for AIDS-orphaned children in Mbeya Rural District in Tanzania. The framework approach was used to analyse the data that were collected from 15 July to 15 August 2010. The study findings revealed that adoptive families faced several challenges including financial constraints due to increased needs for basic essentials such as health care expenses, school fees and food. Further impacts on adoptive families included shortage of work opportunities and limited time to address these challenges. To mitigate these challenges, adoptive families employed a range of coping strategies including selling family assets and renting out parts of cultivable land for extra cash. Task reallocation which involved the AIDS-orphaned children entering the labour force was also employed as a strategy to mitigate challenges and involved de-enrolling of children from schools so they could take part in income-generating activities in order to earn supplementary family income. The creation of additional income-generating activities such as poultry farming were other coping mechanisms employed, and these received support from both non-governmental organisations (NGOs) and governmental organisations, including the Isangati Agricultural Development Organization (local

    The immune system has adopted somatic DNA alterations to overcome the limitations of the genomic information. Activation induced cytidine deaminase (AID) is an essential enzyme to regulate class switch recombination (CSR), somatic hypermutation (SHM) and gene conversion (GC) of the immunoglobulin gene. AID is known to be required for DNA cleavage of S regions in CSR and V regions in SHM. However, its molecular mechanism is a focus of extensive debate. RNA editing hypothesis postulates that AID edits yet unknown mRNA, to generate specific endonucleases for CSR and SHM. By contrast, DNA deamination hypothesis assumes that AID deaminates cytosine in DNA, followed by DNA cleavage by base excision repair enzymes. We summarize the basic knowledge for molecular mechanisms for CSR and SHM and then discuss the importance of AID not only in the immune regulation but also in the genome instability.

    Background HIV/AIDS-related stigma and discrimination are significant determinants of HIV transmission in the Caribbean island nation of Trinidad and Tobago (T&T), where the adult HIV/AIDS prevalence is 2.5%. T&T is a spiritually-aware society and over 104 religious groups are represented. This religious diversity creates a complex social environment for the transmission of a sexually transmitted infection like HIV/AIDS. Religious leaders are esteemed in T&T's society and may use their position and frequent interactions with the public to promote HIV/AIDS awareness, fight stigma and discrimination, and exercise compassion for people living with HIV/AIDS (PWHA). Some religious groups have initiated HIV/AIDS education programs within their membership, but previous studies suggest that HIV/AIDS remains a stigmatized infection in many religious organizations. The present study investigates how the perception of HIV/AIDS as a sexually transmitted infection impacts religious representatives' incentives to respond to HIV/AIDS in their congregations and communities. In correlation, the study explores how the experiences of PWHA in religious gatherings impact healing and coping with HIV/AIDS. Methods Between November 2002 and April 2003, in-depth interviews were conducted with 11 religious representatives from 10 Christian, Hindu and Muslim denominations. The majority of respondents were leaders of religious services, while two were active congregation members. Religious groups were selected based upon the methods of Brathwaite. Briefly, 26 religious groups with the largest followings according to 2000 census data were identified in Trinidad and Tobago. From this original list, 10 religious groups in Northwest Trinidad were selected to comprise a representative sample of the island's main denominations. In-depth interviews with PWHA were conducted during the same study period, 2002–2003. Four individuals were selected from a care and support group located in Port of Spain

    Kinect is a motion sensing input device which is widely used in computer vision and other related fields. However, there are many inaccurate depth data in Kinect depth images even Kinect v2. In this paper, an algorithm is proposed to enhance Kinect v2 depth images. According to the principle of its depth measuring, the foreground and the background are considered separately. As to the background, the holes are filled according to the depth data in the neighborhood. And as to the foreground, a filling algorithm, based on the color image concerning about both space and color information, is proposed. An adaptive joint bilateral filtering method is used to reduce noise. Experimental results show that the processed depth images have clean background and clear edges. The results are better than ones of traditional Strategies. It can be applied in 3D reconstruction fields to pretreat depth image in real time and obtain accurate results.

  17. Chile: educational game, "Learning about AIDS: the Responsibility of All".

    PubMed

    1993-01-01

    For more than 10 years, People's Health Education (EPES) has developed educational materials which call upon target audiences to integrate their practical experiences into a collective learning process based upon games. The methodology and materials aim to meet the needs of the most underprivileged sections of the population. EPES produced "Learning about AIDS: the responsibility of all," a game which can be used as it is or adapted to meet the needs of differing groups. The objectives of the game are to provide basic information on AIDS; to facilitate the expression of ideas, beliefs, and myths about AIDS; to promote forums for discussion in order to exchange opinions and views on sexuality and AIDS; to create awareness on how AIDS affects the community; and to create awareness of the need to prevent the disease. Played in couples to strengthen the level of interpersonal communication on such issues, the game is played because AIDS is a fact of everyday life which is affecting the community, because learning about AIDS will help people to protect themselves and their communities from the disease and groundless associated fears, and because open discussion is needed to help prevent more people from becoming infected with HIV.

  18. Long prereproductive selection and divergence by depth in a Caribbean candelabrum coral

    Long-lived corals, the foundation of modern reefs, often follow ecological gradients, so that populations or sister species segregate by habitat. Adaptive divergence maintains sympatric congeners after secondary contact or may even generate species by natural selection in the face of gene flow. Such ecological divergence, initially between alternative phenotypes within populations, may be aided by immigrant inviability, especially when a long period separates larval dispersal and the onset of reproduction, during which selection can sort lineages to match different habitats. Here, we evaluate the strength of one ecological factor (depth) to isolate populations by comparing the genes and morphologies of pairs of depth-segregated populations of the candelabrum coral Eunicea flexuosa across the Caribbean. Eunicea is endemic to the Caribbean and all sister species co-occur. Eunicea flexuosa is widespread both geographically and across reef habitats. Our genetic analysis revealed two depth-segregated lineages. Field survivorship data, combined with estimates of selection coefficients based on transplant experiments, suggest that selection is strong enough to segregate these two lineages. Genetic exchange between the Shallow and Deep lineages occurred either immediately after divergence or the two have diverged with gene flow. Migration occurs asymmetrically from the Shallow to Deep lineage. Limited recruitment to reproductive age, even under weak annual selection advantage, is sufficient to generate habitat segregation because of the cumulative prolonged prereproductive selection. Ecological factors associated with depth can act as filters generating strong barriers to gene flow, altering morphologies, and contributing to the potential for speciation in the sea. PMID:23359716

    In the aftermath of the 7.0 earthquake that struck Lushan in China's Sichuan Province on April 20, 2013, a psychological crisis intervention working group was established in a hospital that was treating earthquake victims. Patients at this hospital received psychological first aid that was delivered in accordance with scientific, systematic, and standardized principles. This first aid employed a "rooting mode" methodology and was designed as a supportive psychological intervention. Mental assessment results showed that the general mental health, acute stress reactions, and anxiety and depression status of all of the 131 injured who received the psychological intervention had significantly improved (p < .05) during the two-week intervention period. This paper introduces the basic principles used to develop and provide this first aid, the approach used to organize the working groups, the main contents of the intervention, specific methods used, and intervention outcomes. This information is provided as a reference for providing localized psychological assistance in the aftermath of a disaster incident.

    The evaluation of hearing-aid fitting includes numerous assessments such as electro- and psychoacoustic tests. The subjective estimation of the hearing aid user can be elicited with self-assessment inventories encompassing various parameters, e.g., benefit, satisfaction and usage. A questionnaire comprising 11 domains (disability, handicap, frequency and significance of the listening situation, importance of the hearing aid, expectation, demand, aided performance, benefit, satisfaction and usage) within three different conditions (speech in quiet and in noise and listening to sounds) was used to detect components underlying hearing aid fitting. The data show a three-factor structure (situation-, restriction- and aid-related variables) independent from the conditions. Usage depends on all of the three factors. Disability and handicap reveal the highest values for speech in noise, whereas the aid-related factor shows the lowest values for this condition. Global satisfaction with the hearing aid is significantly correlated with the aid-related factor, but independent from the restriction of hearing. The aid-related factor is positively influenced by the amount of social activity because more active persons report higher benefit and satisfaction for all listening conditions. Age does not exhibit a significant relationship to one of the components. Basically, all correlation coefficients are only intermediate, revealing that inter-individual differences of the patients are rather high. The data indicate that extra-audiological factors might also play an important role in the success of hearing aid fitting.

    2011-01-01

    HIV/AIDS has had devastating impacts in many countries, Uganda in particular. However, Uganda is depicted as one of the most successful countries in fighting HIV/AIDS. Among others, Uganda's success story is attributed to the open general environment which allows open discussions surrounding HIV/AIDS when other countries such as South Africa and Kenya denied the existence of the disease in their countries. In addition, the success is attributed to the policy which allowed many actors to participate in the fight against the disease. The primary focus of this article is to map the process of social capital generation by NGOs and how social capital benefits enhance mitigation of HIV/AIDS challenges in Uganda. The key to social capital is nurturing relationships. In this regard, HIV/AIDS NGOs play a central role in the way individuals, groups and communities interact, and how various kinds of social relations are forged with people living with HIV/AIDS and especially for those who are HIV infected. NGOs' success in reducing the number of HIV/AIDS cases in Uganda is based on their abilities to generate social capital. This involves inclusion and building social networks and empowerment at the individual and community levels, and disseminating information to reduce social stigma as well as discrimination. We used a mixed-method strategy to collect data for this study. We used a structured questionnaire having quantitative and qualitative question sets which focused on different social capital measurement indicators. We used observations and in-depth face-to-face interviews. A major finding of the study is that the ways individuals and groups are connected and interact with each other are important mechanisms for alleviating HIV/AIDS challenges in Uganda.

    This pilot study aimed to investigate whether revising a hearing aid user guide (HAUG) is associated with improved hearing aid self-efficacy and utility performance. In Part 1, an HAUG was evaluated using the Suitability Assessment of Material (SAM) and readability formulas (Flesch Reading Ease [Flesch, 1943], Flesch-Kincaid Readability Formula [Kincaid, Fishburne, Rogers, & Chissom, 1957], and Simple Measure of Gobbledygook [McLaughlin, 1969]). The HAUG was revised using results from the SAM and best practice guidelines. The revision included generating a video. In Part 2, 30 adults with hearing impairment were randomly assigned to use either the original guide (N = 15) or the revised guide and video (N = 15) to perform a utility task. Participants' self-efficacy was measured using the Basic and Advanced Handling subscales of the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids questionnaire. SAM and readability were compared between the original and revised guides (Doak, Doak, & Root, 1996). SAM and readability were improved following the revision. Participants in the revised guide group performed significantly better on the utility task and on the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids subscales than participants in the original guide group. These results are encouraging as they indicate that there is scope to influence self-efficacy and utility performance through the use of appropriate HAUGs.

  3. Women and AIDS caregiving: women's work?

    PubMed

    In this ethnographic study, I examine personal, kinship, and social obligations and the role of women in the traditional Thai family. Under what circumstances do women take on the responsibility to care or not care, and how do they cope with the disease and care when they are also infected? Fifteen women who were afflicted or affected by HIV/AIDS participated in in-depth interviews and participant observations. Analysis employed mainly qualitative methods following Spradley. I show that women who are responsible for caring for both themselves and others, including members of their immediate families or extended family members, face a double jeopardy by virtue of their inferior role and status. When HIV-infected women experience illness, sometimes they feel split; they are incapable of functioning normally, yet they are obligated to do "What they've got to do." Women as carers feel that they have to care because they want to free someone else from suffering despite the fact that they are also suffering. Women roles as family carers seem to be both psychologically and socially constructed. AIDS care is not just a labour of love, but also is done in the spirit of work following Buddhist beliefs of karma and metta. In conclusion, traditional, persistent gender imbalances and inequalities influence women's sexuality, vulnerability, responsibility, and caregiving. When women become infected with HIV and sick with AIDS, their quality of life drops because of the physical, psychological, cultural value, and economic burdens of care they face. AIDS then necessitates rather than prevents women from fulfilling their multiple roles. Consequently, there is a need for greater support especially among Thai women who are afflicted and affected with AIDS.

  4. Stereo depth distortions in teleoperation

    In teleoperation, a typical application of stereo vision is to view a work space located short distances (1 to 3m) in front of the cameras. The work presented here treats converged camera placement and studies the effects of intercamera distance, camera-to-object viewing distance, and focal length of the camera lenses on both stereo depth resolution and stereo depth distortion. While viewing the fronto-parallel plane 1.4 m in front of the cameras, depth errors are measured on the order of 2cm. A geometric analysis was made of the distortion of the fronto-parallel plane of divergence for stereo TV viewing. The results of the analysis were then verified experimentally. The objective was to determine the optimal camera configuration which gave high stereo depth resolution while minimizing stereo depth distortion. It is found that for converged cameras at a fixed camera-to-object viewing distance, larger intercamera distances allow higher depth resolutions, but cause greater depth distortions. Thus with larger intercamera distances, operators will make greater depth errors (because of the greater distortions), but will be more certain that they are not errors (because of the higher resolution).

    There is a close relationship between groundwater level in a shallow aquifer and the surface ecological environment; hence, it is important to accurately simulate and predict the groundwater level in eco-environmental construction projects. The multiple linear regression (MLR) model is one of the most useful methods to predict groundwater level (depth); however, the predicted values by this model only reflect the mean distribution of the observations and cannot effectively fit the extreme distribution data (outliers). The study reported here builds a prediction model of groundwater-depth dynamics in a shallow aquifer using the quantile regression (QR) method on the basis of the observed data of groundwater depth and related factors. The proposed approach was applied to five sites in Tianjin city, north China, and the groundwater depth was calculated in different quantiles, from which the optimal quantile was screened out according to the box plot method and compared to the values predicted by the MLR model. The results showed that the related factors in the five sites did not follow the standard normal distribution and that there were outliers in the precipitation and last-month (initial state) groundwater-depth factors because the basic assumptions of the MLR model could not be achieved, thereby causing errors. Nevertheless, these conditions had no effect on the QR model, as it could more effectively describe the distribution of original data and had a higher precision in fitting the outliers.

    2000-01-01

    This paper focuses on the impact of HIV/AIDS on child survival and development in Kenya. The rapid spread of HIV, mainly through heterosexual contact and mother-to child transmission, contributes to the increasing rates of infant and under-five mortality in Kenyan provinces. Moreover, the impact of AIDS on the well-being of children is likely to worsen, as preliminary findings of the 1999 sentinel surveillance data indicate that HIV prevalence among the adult population is still rising. Poverty increases the vulnerability of children to HIV/AIDS. In addition, it may increase the likelihood that women become commercial sex workers as an alternative source of income. Poverty also increases the risk of illness and death through poor access to basic services. Poor environmental sanitation and lack of access to safe water sources increase the vulnerability of children to the impact of the infection. As a consequence, more and more children will be infected and affected by HIV/AIDS, and the ability of HIV-positive parents to care for their children will be impaired, while the number of orphans will continue to increase dramatically as parents die within a short period. Recommended strategies in combating the epidemic and improving the well-being of children are outlined.

    To compare intra- and inter-observer reliability of aneurysm measurements obtained by a 3D computer-aided technique with standard manual aneurysm measurements in different imaging modalities. A total of 21 patients with 29 cerebral aneurysms were studied. All patients underwent digital subtraction angiography (DSA), contrast-enhanced (CE-MRA) and time-of-flight magnetic resonance angiography (TOF-MRA). Aneurysm neck and depth diameters were manually measured by two observers in each modality. Additionally, semi-automatic computer-aided diameter measurements were performed using 3D vessel surface models derived from CE- (CE-com) and TOF-MRA (TOF-com) datasets. Bland-Altman analysis (BA) and intra-class correlation coefficient (ICC) were used to evaluate intra- and inter-observer agreement. BA revealed the narrowest relative limits of intra- and inter-observer agreement for aneurysm neck and depth diameters obtained by TOF-com (ranging between ±5.3 % and ±28.3 %) and CE-com (ranging between ±23.3 % and ±38.1 %). Direct measurements in DSA, TOF-MRA and CE-MRA showed considerably wider limits of agreement. The highest ICCs were observed for TOF-com and CE-com (ICC values, 0.92 or higher for intra- as well as inter-observer reliability). Computer-aided aneurysm measurement in 3D offers improved intra- and inter-observer reliability and a reproducible parameter extraction, which may be used in clinical routine and as objective surrogate end-points in clinical trials.

    The idea that basic science should be the starting point for modern clinical approaches has been consolidated over the years, and emerged as the cornerstone of Molecular Medicine. Nevertheless, there is increasing concern over the low efficiency and inherent costs related to the translation of achievements from the bench to the bedside. These burdens are also perceived with respect to the effectiveness of translating basic discoveries in stem cell biology to the newly developing field of advanced cell therapy or Regenerative Medicine. As an alternative paradigm, past and recent history in Medical Science provides remarkable reverse stories in which clinical observations at the patient's bedside have fed major advances in basic research which, in turn, led to consistent progression in clinical practice. Within this context, we discuss our recently developed method and device, which forms the core of a system (Lipogems) for processing of human adipose tissue solely with the aid of mild mechanical forces to yield a microfractured tissue product.

    Purpose To study the impact of the depth of focus on subjective refraction and distribution of myopic and hyperopic refractions. Methods A total of 450 eyes of 305 subjects in the age range of 23–34 years were recruited for the study. A distribution of refractions was examined using a traditional method of the subjective refractometry on the basis of point-like posterior focus notion. Correction of the results was made on the assumption that the emmetropic eye retains high visual acuity when applying convex lenses with values which are fewer or equal to the depth of focus values. The following values of the depth of focus were used: ±0.55 D, ±0.35 D and ±0.2 D for visual acuity 1.0, 1.5 and 2.0, respectively. Results Application of the traditional method of refractometry produced the following occurrence of refractions: hypermetropia 59.3%, myopia 22% and emmetropia 18.7%. After correction of the initial results of values of the depth of focus the distribution of refractions was as follows: hypermetropia 12.7%, myopia 22% and emmetropia 65.3%. Conclusion The traditional method of subjective refractometry with application of trial lenses was developed on the basis of data of large optical aberrations and significant depth of focus which values should be taken into account during interpretation of results of subjective refractometry. Our data regarding to prevalence of emmetropic refraction falls in line with basic science provisions in respect of the physiology of the eye.

    In 1997, at the Davos International Economic Forum, Nelson Mandela stated that "the poor, the vulnerable, the unschooled, the socially marginalized, the women, and the children, those who bear the burden of colonial legacy-these are the sectors of society which bear the burden of AIDS" (Richter, 2001). Nearly a decade later, that statement still holds true, especially in Mr. Mandela's home country. South Africa continues to have one of the world's highest prevalence ratios of HIV infection (UNAIDS, 2002). This paper explores the significance of perceptions, knowledge, practices, and attitudes toward HIV/AIDS in two important groups in South Africa: health care providers based in public health clinics and their patients. This paper will assess the provider-patient interaction from the perspective of members of the South African HIV/AIDS treatment and prevention community. The analysis will examine the results of in-depth interviews and focus group discussions with providers and patients, respectively, in two of South Africa's nine provinces. Between December 2002 and April 2003 in Guateng and KwaZulu-Natal provinces, we conducted (1) in-depth interviews of a spectrum of health care providers at five local public health clinics and (2) focus groups of patients who patronize those clinics. The results show that there are gaps in the HIV/AIDS knowledge of some of the health care providers and that the participants' health beliefs and practices are embedded in the social conditions in which they live and work, which has a ripple effect on their risk behaviors and trumps any intervention messages from their health care providers and larger public health intervention messages.

    The task involved in the interpretation of Vertical Electrical Sounding (VES) data is how to get unique results in the absence/limited number of borehole information, which is usually limited to information on the spot. Geological and geochemical mapping of electrical properties are usually limited to direct observations on the surface and therefore, conclusions and extrapolations that can be drawn about the system electrical characteristics and possible underlying structures may be masked as geology changes with positions. The electrical resistivity study pedotransfer functions (PTFs) have been linked with the electromagnetic (EM) resolved PTFs at chosen frequencies of skin/penetration depth corresponding to the VES resolved investigation depth in order to determine the local geological attributes of hydrogeological repository in the coastal formation dominated with fine sand. The illustrative application of effective skin depth depicts that effective skin depth has direct relation with the EM response of the local source over the layered earth and thus, can be linked to the direct current earth response functions as an aid for estimating the optimum depth and electrical parameters through comparative analysis. Though the VES and EM resolved depths of investigation at appropriate effective and theoretical frequencies have wide gaps, diagnostic relations characterising the subsurface depth of interest have been established. The determining factors of skin effect have been found to include frequency/period, resistivity/conductivity, absorption/attenuation coefficient and energy loss factor. The novel diagnostic relations and their corresponding constants between 1-D resistivity data and EM skin depth are robust PTFs necessary for checking the accuracy associated with the non-unique interpretations that characterise the 1-D resistivity data, mostly when lithostratigraphic data are not available.

    The photography of people with AIDS has been subject to numerous critiques in the 1980s and has become a controversial way of visualizing the AIDS epidemic. While most of the scholarly work on AIDS photography is based in cultural studies and concerned with popular representations, the clinical value of photographs of people with AIDS usually remains overlooked. This article addresses photographs as a "way of seeing" AIDS that contributed crucially to the making of the disease entity AIDS within the history of medicine. Cultural studies methods are applied to analyze clinical photography in the case of AIDS, thus contributing to the medical history of AIDS through the lens of photography. The article reveals the conflation of disease morphology and patient identity as a characteristic feature of both clinical photography and a now historical nature of AIDS.

  15. Depth related trends in proximate composition of demersal fishes in the eastern North Pacific

    The proximate chemistry of the white muscle and liver of 18 species of demersal fish from the eastern North Pacific was studied to determine trends with depth, locomotory mode and buoyancy mechanism, foraging strategy and to elucidate energetic strategies. Data for 24 species from shallow water were taken from the literature and included for analysis of muscle water content. Benthopelagic species, primarily gadiforms, have significantly larger lipid-rich livers than benthic species. The benthopelagic species may use this lipid to add buoyancy, but it is also used as energy storage. Buoyancy mechanism was directly related to proximate composition. Fishes using gasbladders had normal muscle composition. The two species of benthopelagic fishes without gasbladders have either very high muscle lipid content ( Anoplopoma fimbria) or gelatinous muscle ( Alepocephalus tenobrosus) to aid in achieving neutral buoyancy. The macrourid, Albatrossia pectoralis, has a very small gasbladder and also has gelatinous muscle. Both of these benthopelagic fishes with gelatinous muscle feed on pelagic organisms. Gelatinous muscle was also found in two flatfishes that inhabit the oxygen minimum zone. For these fishes, high water content may serve to lower metabolic costs while maintaining large body size. Scavengers such as Coryphaenoides armatus and Coryphaenoides acrolepis have lipid rich livers and others such as A. fimbria and Pachycara sp. have high and variable muscle lipid content. Thus foraging mode also acts to influence proximate composition. Several depth-related trends in proximate composition were found. White muscle water content increased significantly with depth, and all four gelatinous species occurred at bathyal depths. This adds evidence in support of the hypothesis that decreasing light levels shorten reactive distances and relax the selective pressure for high locomotory capacity. In addition significant declines in liver protein content were observed, suggesting that

    We examined the meaning of living with HIV/AIDS among women in Lebanon. Ten women living with HIV/AIDS (WLWHA) described their experiences via semistructured in-depth interviews. They navigated a process of HIV diagnosis acceptance that incorporated six overlapping elements: receiving the news, accessing care, starting treatment, navigating disclosure decisions, negotiating stigma, and maintaining stability. Through these elements, we provide a framework for understanding three major themes that were constructed during data analysis: Stand by my side: Decisions of disclosure; Being "sick" and feeling "normal": Interacting with self, others, and society; and Living day by day: focusing on the present. We contribute to the existing literature by providing a theoretical framework for understanding the process of diagnosis and sero-status acceptance among WLWHA. This was the first study of its kind to examine the meaning of living with HIV/AIDS among women in a Middle Eastern country.

    Progress realized in the development of a Computer Aided Grid Interface (CAGI) software system in integrating CAD/CAM geometric system output and/or Interactive Graphics Exchange Standard (IGES) files, geometry manipulations associated with grid generation, and robust grid generation methodologies is presented. CAGI is being developed in a modular fashion and will offer fast, efficient and economical response to geometry/grid preparation, allowing the ability to upgrade basic geometry in a step-by-step fashion interactively and under permanent visual control along with minimizing the differences between the actual hardware surface descriptions and corresponding numerical analog. The computer code GENIE is used as a basis. The Non-Uniform Rational B-Splines (NURBS) representation of sculptured surfaces is utilized for surface grid redistribution. The computer aided analysis system, PATRAN, is adapted as a CAD/CAM system. The progress realized in NURBS surface grid generation, the development of IGES transformer, and geometry adaption using PATRAN will be presented along with their applicability to grid generation associated with rocket propulsion applications.

    A study of the knowledge, attitudes, beliefs and practices (KABP) relating to HIV/AIDS was conducted among people from Bangladesh seeking work overseas (N = 300), during February, 1997 and March, 1997. Only 26% of the respondents knew of AIDS and out of 13 basic facts concerning HIV/AIDS the mean score of the sample was 1.63 correct responses. Most of those who knew of HIV had some false beliefs about the mode of HIV transmission, for example, believing that HIV could be contracted by touching an AIDS patient, or sharing bathing facilities or eating utensils. Sex with brothel-based commercial sex workers (100%), sharing contaminated needles (93.6%) and blood transfusion from infected individuals (93.6%) were seen as the main route of HIV transmission. Printed media (69%) was the main source of AIDS information. Multiple logistic regression analysis showed that having a non-agricultural occupation (P < 0.04), being resident in Dhaka, Chandpur, Noakhali, Comilla, and Chittagong (P < 0.01), being in the habit of reading newspapers (P < 0.05), using condoms (P < 0.04), having heard about condoms (P < 0.003), having seen condoms (P < 0.005) and knowing where to buy condoms (P < 0.0005) were significantly associated with AIDS awareness. There is insufficient AIDS awareness among overseas job seekers which calls for public initiatives to provide AIDS information to them before they leave Bangladesh to work abroad.

    2014-05-01

    To establish whether complex signal processing is beneficial for users of bone anchored hearing aids. Review and analysis of two studies from our own group, each comparing a speech processor with basic digital signal processing (either Baha Divino or Baha Intenso) and a processor with complex digital signal processing (either Baha BP100 or Baha BP110 power). The main differences between basic and complex signal processing are the number of audiologist accessible frequency channels and the availability and complexity of the directional multi-microphone noise reduction and loudness compression systems. Both studies show a small, statistically non-significant improvement of speech understanding in quiet with the complex digital signal processing. The average improvement for speech in noise is +0.9 dB, if speech and noise are emitted both from the front of the listener. If noise is emitted from the rear and speech from the front of the listener, the advantage of the devices with complex digital signal processing as opposed to those with basic signal processing increases, on average, to +3.2 dB (range +2.3 … +5.1 dB, p ≤ 0.0032). Complex digital signal processing does indeed improve speech understanding, especially in noise coming from the rear. This finding has been supported by another study, which has been published recently by a different research group. When compared to basic digital signal processing, complex digital signal processing can increase speech understanding of users of bone anchored hearing aids. The benefit is most significant for speech understanding in noise.

    When performed effectively, cardiopulmonary resuscitation (CPR) by bystanders reduces mortality due to sudden cardiac arrest. Telemedicine applications offer a means by which bystanders can get specific instructions for handling the emergency situation. M-AID, a first aid application for mobile phones, uses an intelligent algorithm of 'yes' or 'no' questions to judge the ongoing situation and give the user detailed instructions. The aim of this study was to evaluate the benefit of this mobile phone application in a scenario of sudden cardiac arrest. One hundred and nineteen volunteers were assigned at random either to the test or the control group. All participants were confronted with the same scenario of acute coronary syndrome leading to cardiac arrest. The participants were either equipped with a mobile phone running the software (test group) or had to handle the situation without support (control group). The participants received a certain amount of credits for each action taken according to a pre-defined protocol and these credits were added to a score and compared between the groups. Participants were divided into subgroups according to their medical and technical experience. The test group generally achieved a slightly higher average score that was not statistically significant (21.11 versus 19.97; p=0.302). In contrast, the performance of the individuals in the control group was significantly faster (2.41 min versus 4.24 min; p<0.001). Use of the mobile phone software did not enhance the chance of survival. Subgroup analysis showed that experienced mobile phone users performed significantly better than non-experienced individuals, but not as well as participants with advanced first aid knowledge. Experience in the use of mobile phones is a prerequisite for the efficient use of the tested M-AID version. This application cannot replace skills acquisition by practical training. In a subgroup with experience in mobile phone use and basic knowledge in CPR, the

    This paper presents a novel wheeled probe for the purpose of aiding a surgeon in soft tissue abnormality identification during minimally invasive surgery (MIS), compensating the loss of haptic feedback commonly associated with MIS. Initially, a prototype for validating the concept was developed. The wheeled probe consists of an indentation depth sensor employing an optic fibre sensing scheme and a force/torque sensor. The two sensors work in unison, allowing the wheeled probe to measure the tool-tissue interaction force and the rolling indentation depth concurrently. The indentation depth sensor was developed and initially tested on a homogenous silicone phantom representing a good model for a soft tissue organ; the results show that the sensor can accurately measure the indentation depths occurring while performing rolling indentation, and has good repeatability. To validate the ability of the wheeled probe to identify abnormalities located in the tissue, the device was tested on a silicone phantom containing embedded hard nodules. The experimental data demonstrate that recording the tissue reaction force as well as rolling indentation depth signals during rolling indentation, the wheeled probe can rapidly identify the distribution of tissue stiffness and cause the embedded hard nodules to be accurately located.

    Basic needs are defined as goods or services that are essential for human to live and function. Wants on the other hand, are goods or services that are not necessary but we desire or wish for in order to fulfil our needs. In university, students' needs and wants are not always easily detectable due to different generations of students. The students' desires are also caused by peer interactions, course needs and cultural differences. For example older generations requires typewriter but new generations need a laptop. Many university students have difficulty to differentiate between basic needs and wants. This leads to financial management problem which can affect their academic performance. The purpose of this study is to identify students of Universiti Utara Malaysia (UUM) basic needs. Based on past studies conducted by 3 universities, 12 items related to students' basic needs were identified. However, only 9 items are considered relevant to UUM students. A study on a focus group consist of 18 students from different background was conducted to validate the 9 items of basic needs by using in depth interviews. The findings indicated food, clothing, books, stationery, photocopying, printing & binding, information & communication technology (ICT), mobile phone bills, transportation and others (which includes toiletries, groceries, sport, & entertainment) as the 9 items. The findings also revealed that student basic needs for ICT are not only laptop and printer but also a smartphone. As for clothing, requirements are different according to programs the student majors in. A business student need full business attire, law students need a proper robe for moot courts and curriculum activities require the students to be in uniform. These are basic needs and not desires or wants.

    This book is concerned with the basic relations regarding a new approach in the field of knowledge of metallogenesis, taking into account the complex character of the mutual dependence between ore deposits, the structure of the earth's crust, and depth relations. The principles of nonlinear metallogeny are examined, giving attention to the development of the metallogenic science during the past few years, the formation of the concept 'nonlinear metallogeny', the main aspects of nonlinear metallogeny, the origin of the ore deposits and the characteristics of ore formations in the mantle, the parallel manifestation of ore-forming processes in the crust, sedimentary-hydrothermal ore formations and their place in nonlinear metallogeny, and various types of rock and ore formations. The structure, composition, and metalliferous characteristics found at various depth zones of the tectonosphere are discussed along with the geochemical and metallogenic heterogeneity in the mantle. General questions of nonlinear metallogeny are also investigated.

    This study analyses the way in which the Italian press reported Acquired Immunodeficiency Syndrome (AIDS) over a 22-month period from September 1993 to June 1995, when no national AIDS information campaigns were made in Italy. During this period we collected, read, and categorized every article relating to Human Immunodeficiency Virus (HIV) and AIDS in fourteen newspapers and two news magazines with the highest national circulation. Articles were then assigned to one of six content categories: statistics, basic science, cure and vaccine, education/awareness and prevention issue, government or non-goverment organizations response, and people with AIDS (PWA) personal portrayals. A total of 4,228 articles referring to HIV/AIDS were identified. Analysis of the featured topics reveals several clear differences in the coverage of aspects of AIDS. The major category was represented by government or non-goverment organization response which accounted for 1,341 articles. Overall, this analysis suggests that, even long after the beginning of the epidemic, the press continues to see AIDS as an important issue. However, the articles explaining scientifically the AIDS epidemic were very few. The majority of AIDS-related information was spread in consequence of sensational events. Further analysis of PWA coverage shows that most articles discussed news that could provoke a negative feeling towards HIV-infected patients among the general population.

    Perception is fundamental in the fight against stigmatization of people living with HIV/AIDS (PLHIV). Perception generally influences discriminatory attitudes towards PLHIV which exacerbates their problems and quickens the degeneration of the disease from HIV to AIDS. This study examined the Anambra people's perception and knowledge of HIV/AIDS with the goal of creating knowledge on these issues in order to design effective intervention programmes towards the reduction of social stigmatization associated with the pandemic. The study was carried out in Idemmili North and Oyi local government areas of Anambra State. Qualitative and quantitative methodologies were used to elicit information from respondents who were adult males and females of 18 years and above. The research instruments were questionnaires and in-depth interview schedule. Questionnaires were administered on 1000 respondents while 13 people were interviewed in-depth. Analysis of quantitative data were conducted by using the Statistical package for Social Sciences. Univariate analysis in the form of frequencies were conducted which generated the distribution of respondents across the research variables. Furthermore, multivariate analysis were conducted to test the hypotheses and sought for relationships among variables. The qualitative data were reported in themes based on the research objectives and were analysed jointly with the quantitative data. The findings were that majority of the respondents viewed HIV/AIDS as a disease that afflict immoral people and as a punishment from God. Only a handful of them saw the disease as a disease that could afflict anybody. Also, many of the respondents said that AIDS is real but showed a low level of knowledge. It was further indicated that there were significant relationships between educational level, sex, occupation, income influence perception and peoples' reactions to HIV positive status of a relative while there were no significant relationships between

    This article contains five key pieces of labor legislation in South Africa, including one applying specifically to the mining industry which protect the rights of employees. These laws include: the Employment Equity Act, No. 55 of 1998; the Labour Relations Act, No. 66 of 1995; the Occupational Health and Safety Act, No. 85 of 1993; the Compensation for Occupational Injuries and Diseases Act No. 130 of 1993; the Mines Health and Safety Act, No. 29 of 1996; and the Basic Conditions of Employment Act, No. 75 of 1997. This paper further presents the Medical Schemes Act, No. 131 of 1998 and the protection of the right to privacy and dignity. Although HIV/AIDS was expressly referred to only in the Employment Equity Act, there are provisions in all the other Acts, which have relevance to HIV/AIDS.

    Behaviour change models in HIV prevention tend to consider that risky sexual behaviours reflect risk assessments and that by changing risk assessments behaviour can be changed. Risk assessment is however culturally constructed. Individuals use heuristics or bounded cognitive devices derived from broader cultural meaning systems to rationalize uncertainty. In this study, we identify some of the cultural heuristics used by migrant men in Goa, India to assess their risk of HIV infection from different sexual partners. Data derives from a series of in-depth interviews and a locally informed survey. Cultural heuristics identified include visual heuristics, heuristics of gender roles, vigilance and trust. The paper argues that, for more culturally informed HIV/AIDS behaviour change interventions, knowledge of cultural heuristics is essential.

    This paper examines the activities of churches in Baltimore, Maryland, concerning the issues of sexuality, whether they potentially stigmatize persons with or at risk for HIV/AIDS, and to what extent individual agency versus institutional forces influence churches in this regard. In-depth interviews were conducted with 20 leaders from 16 churches and analyzed using a grounded theory methodology. Although many churches were involved in HIV/AIDS-related activities, the content of such initiatives was sometimes limited due to organizational constraints. Church leaders varied, however, in the extent to which they responded in accordance with or resisted these constraints, highlighting the importance of individual agency influencing churches’ responses to HIV/AIDS.

    2004-07-01

    AIDS-related stigmas are pervasive in some segments of South African society and stigmas can impede efforts to promote voluntary counselling and testing and other HIV-AIDS prevention efforts. The current study examined associations among the belief that AIDS is caused by spirits and supernatural forces, AIDS-related knowledge and AIDS-related stigmas. A street intercept survey with 487 men and women living in a Black township in Cape Town, South Africa showed that 11% (n=54) believed that AIDS is caused by spirits and supernatural forces, 21% (n=105) were unsure if AIDS is caused by spirits and the supernatural, and 68% (n=355) did not believe that AIDS is caused by spirits and supernatural forces. Multiple logistic regression analyses controlling for participant age, gender, years of education and survey venue showed that people who believed HIV-AIDS is caused by spirits and the supernatural demonstrated significantly more misinformation about AIDS and were significantly more likely to endorse repulsion and social sanction stigmatizing beliefs against people living with HIV-AIDS. However, nearly all associations between beliefs that AIDS is caused by spirits and AIDS stigmas were non-significant when logistic regressions were repeated with AIDS-related knowledge included as a control variable. This finding suggests that relationships between traditional beliefs about the cause of HIV-AIDS and AIDS stigmas are mediated by AIDS-related knowledge. AIDS education efforts are urgently needed to reach people who hold traditional beliefs about AIDS to remedy AIDS stigmas.

    Recently, the food and malnutrition issues have taken centre stage within the arena of HIV/AIDS epidemic, with several calls being made for context-specific health and nutrition interventions to deal with the emerging food insecurity and malnutrition issues in settings with high burdens of HIV/AIDS. The use of probiotics as nutritional supplements in HIV/AIDS-affected and resource-poor settings has also been advocated. This paper presents the results of a qualitative study on community knowledge and perceptions about probiotics and their potential impact on people's everyday life in the context of the HIV/AIDS epidemic. In-depth interviews (n=26) were conducted with residents in Mwanza, Tanzania. The results showed that people living with HIV/AIDS, who were using probiotic yogurt produced through a joint partnership of Western Heads East, Tanzania Medical Research Institute and the Tukwamune Women's Group, reported perceived beneficial effects, such as gain in weight and improved health and well-being. Yet, these beneficial effects might be resulting in growing misconceptions about probiotic yogurt being ‘medicine’ for the treatment of HIV/AIDS; this is leading some people living with HIV/AIDS to abandon taking their antiretroviral medications based on the view that the probiotic yogurt is making them feel much better. The findings illustrate the potential challenges with regard to the introduction of nutritional food supplements into new contexts plagued by malnutrition and infectious diseases. Public-health education and awareness programmes are needed when introducing novel foods into such contexts. PMID:22524117

    Aim of the study Bystanders can play an important role in the event of sudden injury or illness. Our aim was to evaluate the effects of a 3-day first aid course for all primary school age groups (7–14 years old). Methods 582 school children were involved in the study. Training consisted of three sessions with transfer of theoretical knowledge and practical skills about first aid. The following most urgent situations were addressed in our study: adult basic life support (BLS), using an automated external defibrillator (AED), handling an unconscious patient, managing bleeding and calling the ambulance. Data collection was made with a questionnaire developed for the study and observation. Students were tested before, immediately after and 4 months after training. Results were considered significant in case of p<0.05. Results Prior to training there was a low level of knowledge and skills on BLS, management of the unconscious patient, use of an AED and management of bleeding. Knowledge and skills improved significantly in all of these categories (p<0.01) and remained significantly higher than the pre-test level at 4 months after training (p<0.01). Younger children overall performed less well than older children, but significantly improved over the pre-test level both immediately and 4 months after training (p<0.01). Prior first aid training was associated with knowledge of the correct ambulance number (p=0.015) and management of bleeding (p=0.041). Prior to training, age was associated with pre-test knowledge and skills of all topics (p<0.01); after training, it was only associated with AED use (p<0.001). There was a significant correlation between the depth of chest compression and children’s age, weight, height and body mass index (p<0.001). Ventilation depended on the same factors (p<0.001). Conclusion Children aged 7–14 years are able to perform basic life-saving skills. Knowledge retention after 4 months is good for skills, but thinking in algorithms is

    With funding for the Competence Networks in Medicine from the Federal Ministry of Education and Research, the Competence Network for HIV/AIDS (KompNet HIV/AIDS) was established as an interdisciplinary research association. Essential working groups were incorporated all over Germany, which are active in clinical and basic HIV/AIDS research. After successful establishment, providing research infrastructure for national and international cooperation in the field of HIV/AIDS was the focus of the network. By bringing together research activities, preconditions are created for improving HIV infection treatment and increasing life expectancy of HIV-infected patients. The members of KompNet HIV/AIDS are HIV experts from university clinics, HIV physicians, patient representatives, as well as national reference centers. As a scientific research basis, the network established an HIV patient cohort. Clinical and sociodemographic data of HIV patients were documented biannually and complemented by serum and DNA-samples collected twice per year. Furthermore, a child cohort was set up. Within the KompNet HIV/AIDS, a research infrastructure for HIV was established for internal, external as well international scientists. Within the HIV cohort a total of 16,500 patients are documented. The associated biobank comprises ~ 56,000 serum samples and ~ 16,000 DNA samples. The child cohort consists of 647 HIV-exposed and 230 infected children. The KompNet HIV/AIDS cohorts became an important partner in several international collaborations. Nevertheless, the maintenance of such infrastructures without public funding is a challenge.

    Depth measurement is the most basic measurement in various machine vision, such as automatic driving, unmanned aerial vehicle (UAV), robot and so on. And it has a wide range of use. With the development of image processing technology and the improvement of hardware miniaturization and processing speed, real-time depth measurement using dual cameras has become a reality. In this paper, an embedded AM5728 and the ordinary low-cost dual camera is used as the hardware platform. The related algorithms of dual camera calibration, image matching and depth calculation have been studied and implemented on the hardware platform, and hardware design and the rationality of the related algorithms of the system are tested. The experimental results show that the system can realize simultaneous acquisition of binocular images, switching of left and right video sources, display of depth image and depth range. For images with a resolution of 640 × 480, the processing speed of the system can be up to 25 fps. The experimental results show that the optimal measurement range of the system is from 0.5 to 1.5 meter, and the relative error of the distance measurement is less than 5%. Compared with the PC, ARM11 and DMCU hardware platforms, the embedded AM5728 hardware is good at meeting real-time depth measurement requirements in ensuring the image resolution.

    AIDS-orphaned children and adolescents in sub-Saharan Africa have inadequate access to basic services, including health and education. Using a qualitative approach, the study explores the meaning of education in rural Uganda, obstacles faced by AIDS-orphaned adolescents and their caregivers to access secondary education, and the potential of an economic empowerment intervention SEED in addressing the challenges of accessing educational opportunities for AIDS-orphaned adolescents. The findings come from 29 semi-structured interviews conducted with eleven adolescents study participants, four caregivers and fourteen community leaders involved in the pilot SEED intervention. Study participants and community members indicated that the savings accounts offer a unique opportunity for orphaned adolescents to stay in school and imagine the future with optimism. PMID:23543861

    Surface heat flow has been observed to be highly variable in the Nankai subduction margin. This study presents an investigation of local anomalies in surface heat flows on the undulating seafloor in the Nankai subduction margin. We estimate the heat flows from bottom-simulating reflectors (BSRs) marking the lower boundaries of the methane hydrate stability zone and evaluate topographic effects on heat flow via two-dimensional thermal modeling. BSRs have been used to estimate heat flows based on the known stability characteristics of methane hydrates under low-temperature and high-pressure conditions. First, we generate an extensive map of the distribution and subseafloor depths of the BSRs in the Nankai subduction margin. We confirm that BSRs exist at the toe of the accretionary prism and the trough floor of the offshore Tokai region, where BSRs had previously been thought to be absent. Second, we calculate the BSR-derived heat flow and evaluate the associated errors. We conclude that the total uncertainty of the BSR-derived heat flow should be within 25%, considering allowable ranges in the P-wave velocity, which influences the time-to-depth conversion of the BSR position in seismic images, the resultant geothermal gradient, and thermal resistance. Finally, we model a two-dimensional thermal structure by comparing the temperatures at the observed BSR depths with the calculated temperatures at the same depths. The thermal modeling reveals that most local variations in BSR depth over the undulating seafloor can be explained by topographic effects. Those areas that cannot be explained by topographic effects can be mainly attributed to advective fluid flow, regional rapid sedimentation, or erosion. Our spatial distribution of heat flow data provides indispensable basic data for numerical studies of subduction zone modeling to evaluate margin parallel age dependencies of subducting plates.[Figure not available: see fulltext.

    The AIDS pandemic continues to present us with unique scientific and public health challenges. Although the development of effective antiretroviral therapy has been a major triumph, the emergence of drug resistance requires active management of treatment regimens and the continued development of new antiretroviral drugs. Moreover, despite nearly 30 years of intensive investigation, we still lack the basic scientific knowledge necessary to produce a safe and effective vaccine against HIV-1. Animal models offer obvious advantages in the study of HIV/AIDS, allowing for a more invasive investigation of the disease and for preclinical testing of drugs and vaccines. Advances in humanized mouse models, non-human primate immunogenetics and recombinant challenge viruses have greatly increased the number and sophistication of available mouse and simian models. Understanding the advantages and limitations of each of these models is essential for the design of animal studies to guide the development of vaccines and antiretroviral therapies for the prevention and treatment of HIV-1 infection.

  11. AIDS and the law: opportunities and limitations.

    PubMed

    Kirby, M

    1995-01-01

    Laws can only partially succeed in modifying behavior, especially with regard to sex, drug use, and other human pleasures. Effective and just laws to slow the spread of AIDS must therefore be based upon a thorough knowledge of the issues, not upon ignorance, fear, political expediency, or to meet the emotional demands of an often ignorant general population. Good laws, like good ethics, are founded in good data. The most effective response to the AIDS epidemic is neither prohibition nor punishment of individual behavior, but laws designed to truly affect human behavior and shape a society in which the spread of HIV is minimized. Central to an appropriate legislative response is the imperative of protecting the basic rights of individuals infected with HIV. An example of an enlightened, rational, and nondiscriminatory approach to checking the spread of HIV/AIDS while guaranteeing individual freedoms and rights is found in a report commissioned for the State Government of New South Wales. The following measures are recommended to bring state laws into harmony with the national HIV/AIDS strategy: decriminalize brothels, set regulations and public health standards for sex workers, cover sex workers under the Industrial Relations Act, ensure the privacy of HIV/AIDS patients and improve their redress against discrimination in the workplace, repeal laws which make it illegal to possess and administer drugs to oneself, investigate the therapeutic use of marijuana as a prescribed treatment for HIV/AIDS and other terminal illnesses, abandon compulsory testing for HIV in prisons, make condoms available to prisoners and sexually active children, establish a Natural Death Act to allow terminally ill patients to die with dignity, and give legal status to permanent relationships between homosexual couples.

    Matthew P. McAllister wrote: "Comic books can and have contributed positively to the discourse about AIDS: images that encourage true education, understanding and compassion can help cope with a biomedical condition which has more than a biomedical relevance" [1]. With this in mind, I combined a 23-narrator oral history and my personal memoir about an inpatient Chicago AIDS hospital unit in my book, Taking Turns: Stories from HIV/AIDS Care Unit 371. In doing so, I built upon the existing rich history of HIV/AIDS in comics, which this article will briefly describe. Although not a comprehensive review of the intersection of AIDS and comics, the book is a tour through influences that proved useful to me. In addition, in making my book, I faced a distinct ethical issue with regard to representing patient experiences with HIV/AIDS, and I describe here how I addressed it. © 2018 American Medical Association.

    In the spring of 1987, 20 medical students from the Eastern Virginia Medical School of the Medical College of Hampton Roads were involved in a pilot program to teach about the acquired immune deficiency syndrome (AIDS) to high school senior students in Norfolk, Virginia. The medical students received instruction about AIDS from basic science and clinical faculty members at the medical school in preparation for the project. All participating high school seniors completed a 15-item knowledge test about AIDS prior to the intervention and an equivalent posttest one week after the program was completed. T-test analysis revealed a significant increase in knowledge by students at all five high schools. Responses to 10 subjective posttest questions indicated that the high school students were interested in learning about AIDS and having medical students as their teachers. This program provides an example of how medical institutions can develop a collaborative community education project that contributes to the education of medical students.

  14. AIDS, individual behaviour and the unexplained remaining variation.

    PubMed

    Katz, Alison

    2002-01-01

    From the start of the AIDS pandemic, individual behaviour has been put forward, implicitly or explicitly, as the main explanatory concept for understanding the epidemiology of HIV infection and in particular for the rapid spread and high prevalence in sub-Saharan Africa. This has had enormous implications for the international response to AIDS and has heavily influenced public health policy and strategy and the design of prevention and care interventions at national, community and individual level. It is argued that individual behaviour alone cannot possibly account for the enormous variation in HIV prevalence between population groups, countries and regions and that the unexplained remaining variation has been neglected by the international AIDS community. Biological vulnerability to HIV due to seriously deficient immune systems has been ignored as a determinant of the high levels of infection in certain populations. This is in sharp contrast to well proven public health approaches to other infectious diseases. In particular, it is argued that poor nutrition and co-infection with the myriad of other diseases of poverty including tuberculosis, malaria, leishmaniasis and parasitic infections, have been neglected as root causes of susceptibility, infectiousness and high rates of transmission of HIV at the level of populations. Vulnerability in terms of non-biological factors such as labour migration, prostitution, exchange of sex for survival, population movements due to war and violence, has received some attention but the solutions proposed to these problems are also inappropriately focused on individual behaviour and suffer from the same neglect of economic and political root causes. As the foundation for the international community's response to the AIDS pandemic, explanations of HIV/AIDS epidemiology in terms of individual behaviour are not only grossly inadequate, they are highly stigmatising and may in some cases, be racist. They have diverted attention from

    A method to restore the depth map of an RGB-D image using smooth depth neighborhood (SDN) supports is presented. The SDN supports are computed based on the corresponding color image of the depth map. Compared with the most widely used square supports, the proposed SDN supports can well-capture the local structure of the object. Only pixels with similar depth values are allowed to be included in the support. We combine our SDN supports with the joint bilateral filter (JBF) to form the SDN-JBF and use it to restore depth maps. Experimental results show that our SDN-JBF can not only rectify the misaligned depth pixels but also preserve sharp depth discontinuities.

    This paper assesses how decentralization of resources and initiatives by the Brazilian National SDT/AIDS Program has impacted the transfer of funds for programs to prevent HIV/AIDS among injecting drug users in Rio de Janeiro, Brazil (1999-2006). The effects of the decentralization policy on Rio de Janeiro's Syringe Exchange Programs (SEPs) are assessed in detail. Decentralization effectively took place in Rio de Janeiro in 2006, with the virtual elimination of any direct transfer from the Federal government. The elimination of direct transfers forced SEPs to seek alternative funding sources. The structure of local SEPs appears to be weak and has been further undermined by current funding constraints. Of 22 SEPs operating in 2002, only two are still operational in 2006, basically funded by the State Health Secretariat and one municipal government. The current discontinuity of SEP operations may favor the resurgence of AIDS in the IDU population. A more uniform, regulated decentralization process is thus needed.

    Background Migrant populations are at high risk of Human Immuno Deficiency Virus infection (HIV) and Acquired Immunodeficiency Syndrome (AIDS). Studies of HIV/AIDS knowledge, attitudes and practices among fishermen in developing countries have shown gaps in knowledge and fear of contagion with ambivalent attitudes towards HIV/AIDS and inconsistent universal precautions adherence. The aim of this study was to determine the knowledge, attitude and practices regarding HIV/AIDS among adult fishermen in a coastal area of Karachi, Pakistan. Methods Community based cross sectional study was conducted among fishermen in coastal area of Karachi from June to September 2012. A total of 297 adult fishermen were selected by using simple random sampling technique from different sectors of coastal village. Data were collected using a structured validated questionnaire. The frequency distribution of both dependent and independent variables were worked out. Comparisons of knowledge, attitude and practices regarding HIV/AIDS by socio-demographic characteristics were made using logistic regression. Results Out of 297 fishermen, majority had in-appropriate knowledge (93.6%), negative attitude (75.8%) and less adherent sexual practices (91.6%). In univariate analysis, lower education and higher income were significantly associated (OR 2.25, 95% CI, 1.11, 4.55), (OR = 3.04 CI 1.03-9.02, p value 0.04) with negative attitude and un-safe practices towards HIV/AIDS respectively, whereas no significant association of socio-economic characteristics with knowledge, attitude and practices were observed in multivariate analysis. Conclusions This study suggests that fishermen had very poor knowledge, negative attitudes towards HIV and AIDS and had unsafe sexual practices which suggest that they lack the basic understanding of HIV/AIDS infection. Extensive health education campaign should be provided to the vulnerable sections of the society for the control of HIV/AIDS. PMID:24886122

    As the public sector and civil society develop intervention programs to deal with the HIV/ AIDS epidemic, there has been an increasing emphasis on the relationship between nutrition and the disease. Drug interventions may be ineffective, and the progression from HIV infection to full-blown AIDS may be accelerated without adequate nutrition. Mozambique is still fighting an increasing prevalence rate of HIV including in rural areas. Rural households in Mozambique rely heavily on their own agricultural production for the basic macronutrients. To evaluate the extent to which household agricultural production of basic staples meets overall household needs for major macronutrients, comparing households affected and not directly affected by HIV/ AIDS and other major illnesses over two time periods. Methods. This research analyzes nationally representative panel data from rural household surveys conducted in 2002 and 2005 to evaluate whether households that have suffered the chronic illness or illness-related death of prime-age adult members (15 to 49 years of age) are more vulnerable to macronutrient gaps. Households in the South and in the North with a male illness or death in 2002 produced significantly less macronutrients from crops in 2005 than nonaffected households. These households also had significantly lower income per adult equivalent. Mortality or illness from HIV/AIDS affects the ability of agricultural households dependent on own-food production to produce macronutrients. Interventions to improve access to food may be needed for affected households, particularly in light of their inability to recover over time. More analysis is needed to understand income sources, crop diversification, and access to macronutrients through the market.

  2. Family planning: a basic development need.

    PubMed

    1994-06-01

    The 1994 Human Development Report from the United Nations Development Program (UNDP) proposes a 20-20 Human Development Compact based on shared responsibilities between poor and rich nations, whereby poor and rich nations would help unmet basic human development needs such as primary education, primary health care, safe drinking water, and family planning over the next 10 years. This would require an additional US $30 to US $40 billion annually. Developing countries would commit 20% of their budgets to human priority concerns instead of the current 10% by reducing military expenditure, selling off unprofitable public enterprises and abandoning wasteful prestige projects. Donor countries would increase foreign aid from the current average of 7% to 20%. The report will propose a new concept of human security at the World Summit for Social Development to be held in March 1995, calling widespread human insecurity a universal problem. On average, poor nations have 19 soldiers for every one doctor. Global military spending has been declining since 1987 at the rate of 3.6% a year, resulting in a cumulative peace dividend of US $935 billion from 1987 to 1994. But this money has not been expended on unmet human needs. India ordered fighter planes at a cost that could have provided basic education to the 15 million Indian girls now out of school. Nigeria bought tanks from the UK at a cost that could have immunized all 2 million unimmunized children while also providing family planning to nearly 17 million couples. UNDP proposes a phasing out of all military assistance, military bases, and subsidies to arms exporters over a 3-year period. It also recommends the major restructuring of existing aid funds, and proposes a serious study on new institutions for global governance in the next century.

  3. What does sustainability mean in the HIV and AIDS response?

    2016-01-01

    Immense progress has been made in the fight against HIV and AIDS. Achieving and exceeding the AIDS targets for the Millennium Development Goals (MDGs) was accomplished, in large part, due to an unprecedented financial investment from the international community. Following an $800 million dip in donor disbursements in 2010, the discourse has since shifted to the need for greater sustainability of funding. But what does sustainability mean? Current efforts focus heavily on fiscal imperatives such as increasing domestic funding. This is important - needs are increasing at a faster rate than donor funding, especially with increased treatment coverage. The problem is that measures of financial sustainability tell very little about the actual sustainability of specific programmes, disease trajectories or enabling environments. Recognising that current definitions of sustainability lack clarity and depth, we offer a new six-tenet conceptualisation of what sustainability means in the HIV and AIDS response: (1) financial, (2) epidemiological, (3) political, (4) structural, (5) programmatic, and (6) human rights. Based on these, we examine examples of donor transitions for their approach to sustainability, including PEPFAR in South Africa, the Global Fund in Eastern Europe, and the Bill and Melinda Gates Foundation in India (Avahan). We conclude that sustainability must be understood within a broader framework beyond funding stability. We also recommend that certain interventions, such as programming for key populations, may have to continue to receive external support even if affected countries can afford to pay.

  4. Updating default depths in the ISC bulletin

    The International Seismological Centre (ISC) publishes the definitive global bulletin of earthquake locations. In the ISC bulletin, we aim to obtain a free depth, but often this is not possible. Subsequently, the first option is to obtain a depth derived from depth phases. If depth phases are not available, we then use the reported depth from a reputable local agency. Finally, as a last resort, we set a default depth. In the past, common depths of 10, 33, or multiples of 50 km have been assigned. Assigning a more meaningful default depth, specific to a seismic region will increase the consistency of earthquake locations within the ISC bulletin and allow the ISC to publish better positions and magnitude estimates. It will also improve the association of reported secondary arrivals to corresponding seismic events. We aim to produce a global set of default depths, based on a typical depth for each area, from well-constrained events in the ISC bulletin or where depth could be constrained using a consistent set of depth phase arrivals provided by a number of different reporters. In certain areas, we must resort to using other assumptions. For these cases, we use a global crustal model (Crust2.0) to set default depths to half the thickness of the crust.

    The role of older women in the care and protection of vulnerable children in sub-Saharan Africa may be changing given increasing rates of orphanhood due to AIDS. Concern regarding their capacity to provide for children and implications for their health and well-being dominate the literature. However, studies have not yet examined the situation of older caregivers in comparison to their younger counterparts over time. In this study, panel data on 1,219 caregivers in rural Malawi between 2007 and 2009 is complemented by in-depth interview (N=62) and group discussion (N=4) data. Caregiver responsibilities, capacity to care for children, and implications for well-being are examined. Chi-square tests examine differences in these measures between older foster caregivers and younger foster caregivers, parents of orphans, and parents of non-orphans. Older women, in comparison with younger counterparts, are more stable as primary caregivers for orphans. Care by older women is particularly valued when younger family stability is threatened by burdens of orphan care. Qualitative data reveal many challenges that older caregivers face, most notably provision of food. However, survey data suggest that the capacity to provide food, schooling and other basic needs is similar among older and younger caregivers. Self-reported health status is generally poorer among older caregivers, however levels of emotional distress and social capital are similar among older and younger caregivers. Providing care for children in old age appears to entail a number of benefits. Older women committed to providing care and protection for children are important assets, particularly in the context of threats to child well-being due to HIV and AIDS. Bolstering older caregivers with material and social support to help sustain their key roles in fostering is a promising avenue for maintaining extended family responses to HIV and AIDS.

  6. The Roles of Behavioral and Social Science Research in the Fight Against HIV/AIDS: A Functional Framework.

    Landmark advances have been made in HIV/AIDS prevention and treatment. These include proof-of-concept and public health implementation of preexposure prophylaxis and "treatment as prevention" to reduce HIV transmission as well as definitive evidence of the clinical gain from early antiretroviral treatment initiation. Significant progress has been made in understanding and addressing the social contexts and behavioral factors that impact HIV prevention, care, and treatment interventions. These include facilitating uptake of testing and counseling, developing technology-based interventions that increase viral suppression, reducing HIV/AIDS-related stigma, and addressing other sociobehavioral and structural barriers to care and treatment. This evolving landscape provides an important juncture to assess current and future directions for HIV/AIDS behavioral and social science research (BSSR). We propose a functional framework for HIV/AIDS-related BSSR, highlighting 4 primary BSSR domains: (1) understanding vulnerable populations and contexts of risk ("Basic BSSR"); (2) improving behavioral and social factor approaches to risk reduction, prevention, and care ("Elemental BSSR"); (3) strengthening the design and outcomes of biomedically focused research in HIV/AIDS treatment and prevention ("Supportive BSSR"); and (4) contributing building blocks to integrated HIV/AIDS prevention and treatment approaches ("Integrative BSSR"). These domains and their resulting confluence at the highest level underscore how fundamental and essential BSSR is to current and future efforts to prevent, treat, and cure HIV/AIDS.

    Mokhobo, D

    1989-03-01

    Numerous cultural practices and attitudes in Africa represent formidable obstacles to the prevention of the further spread of acquired immunodeficiency syndrome (AIDS). Polygamy and concubinage are still widely practiced throughout Africa. In fact, sexual promiscuity on the part of males is traditionally viewed as positive--a reflection of male supremacy and male sexual prowess. The disintegration of the rural African family, brought about by urbanization, the migrant labor system, and poverty, has resulted in widespread premarital promiscuity. Contraceptive practices are perceived by many as a white conspiracy aimed at limiting the growth of the black population and thereby diminishing its political power. Condom use is particularly in disfavor. Thus, AIDS prevention campaigns urging Africans to restrict the number of sexual partners and to use condoms are unlikely to be successful. Another problem is that most Africans cannot believe that AIDS is sexually linked in that the disease does not affect the sex organs as is the case with other sexually transmitted diseases. The degree to which African governments are able to allocate resources to AIDS education will determine whether the epidemic can be controlled. Even with a massive outpouring of resources, it may be difficult to arouse public alarm about AIDS since Africans are so acclimated to living with calamities of every kind.

    Commercial sex worker is one of the groups with the highest level of susceptibility against HIV infection. They are 13,5 fold more prone to a living with HIV infection than the female of non commercial sex workers. Moreover, these commercial sex workers are also stigmatized with social sanction and discrimination against people with HIV-AIDS. The society mostly avoid them, deject them, isolate them, insult them, despise them, distrust them, and even go against the existence of those suffering from or infected by HIV-AIDS. Thus, stigmatizing and discrimination are basicly highly prohibited since they can incur higher social problems. It is also vital to handle the spread of HIV-AIDS in the society as soon as possible in the attempt of fighting against the spread of the disease. Hence, being broad minded, tolerant, and caring towards them as well as working hand in hand with the community are expected to diminish, minimize, and even eradicate the outbreak of HIV-AIDS. Caring towards those suffering from the infection without stigmatizing them and discriminating them will be one of the first measurements to take to improve what is needed to prevent the prevalence and spread of the disease. Thus, the primary objective of this research is to know the perception of female commercial sex workers on the susceptibility of HIV-AIDS in Yogyakarta. The research participants were selected from three localizations in Yogyakarta namely Pasar Kembang, Bongsuwung, and Giwangan. It is revealed that the participants had a good perception on the susceptibility of AIDS infection as seen from the fact there are free avalaible condoms for them to use everytime they have a sexual intercourse with the clients. All participants were aware of their high susceptibility against the infection of STIs/HIV/AIDS and thus they want to save their skin from those diseases. Also they had a good knowledge that having an intercourse without condom may get them infected.

    A human security framework posits that individuals are the focus of strategies that protect the safety and integrity of people by proactively promoting children's well being, placing particular emphasis on prevention efforts and health promotion. This article applies this framework to a rights-based approach in order to examine the health and human rights of children affected by HIV/AIDS. The SAFE model describes sources of insecurity faced by children across four fundamental dimensions of child well-being and the survival strategies that children and families may employ in response. The SAFE model includes: Safety/protection; Access to health care and basic physiological needs; Family/connection to others; and Education/livelihoods. We argue that it is critical to examine the situation of children through an integrated lens that effectively looks at human security and children's rights through a holistic approach to treatment and care rather than artificially limiting our scope of work to survival-oriented interventions for children affected by HIV/AIDS. Interventions targeted narrowly at children, in isolation of their social and communal environment as outlined in the SAFE model, may in fact undermine protective resources in operation in families and communities and present additional threats to children's basic security. An integrated approach to the basic security and care of children has implications for the prospects of millions of children directly infected or indirectly affected by HIV/AIDS around the world. The survival strategies that young people and their families engage in must be recognized as a roadmap for improving their protection and promoting healthy development. Although applied to children affected by HIV/AIDS in the present analysis, the SAFE model has implications for guiding the care and protection of children and families facing adversity due to an array of circumstances from armed conflict and displacement to situations of extreme poverty.

    Perception is fundamental in the fight against stigmatization of people living with HIV/AIDS (PLHIV). Perception generally influences discriminatory attitudes towards PLHIV which exacerbates their problems and quickens the degeneration of the disease from HIV to AIDS. This study examined the Anambra people's perception and knowledge of HIV/AIDS with the goal of creating knowledge on these issues in order to design effective intervention programmes towards the reduction of social stigmatization associated with the pandemic. The study was carried out in Idemmili North and Oyi local government areas of Anambra State. Qualitative and quantitative methodologies were used to elicit information from respondents who were adult males and females of 18 years and above. The research instruments were questionnaires and in-depth interview schedule. Questionnaires were administered on 1000 respondents while 13 people were interviewed in-depth. Analysis of quantitative data were conducted by using the Statistical package for Social Sciences. Univariate analysis in the form of frequencies were conducted which generated the distribution of respondents across the research variables. Furthermore, multivariate analysis were conducted to test the hypotheses and sought for relationships among variables. The qualitative data were reported in themes based on the research objectives and were analysed jointly with the quantitative data. The findings were that majority of the respondents viewed HIV/AIDS as a disease that afflict immoral people and as a punishment from God. Only a handful of them saw the disease as a disease that could afflict anybody. Also, many of the respondents said that AIDS is real but showed a low level of knowledge. It was further indicated that there were significant relationships between educational level, sex, occupation, income influence perception and peoples' reactions to HIV positive status of a relative while there were no significant relationships between

    This study explores the social representations of HIV and AIDS that circulate among white women teachers in South Africa, a group whose personal risk of the disease is low but who have a major role to play in shaping attitudes to HIV/AIDS among children and young people. The study examines how white women talk about the origin and causes of the spread of HIV in South Africa and their personal and community risk. This was explored through 25 semi-structured interviews and two focus groups with white female teachers in Johannesburg. A thematic analysis of the in-depth interviews revealed a shared private understanding of the disease, wherein the women distanced themselves by anchoring it in the context of racist cultural stereotypes of black sexuality and vulnerability. In contrast, the focus group discussions revealed a type of public talk in which HIV/AIDS is anchored in the contemporary cultural images of the new South Africa and the spirit of ubuntu or togetherness. These contradictory views reflect the racial tensions and social contexts of South Africa and which shape HIV/AIDS discourses. The findings suggest that more needs to be done to create a genuine understanding of HIV and AIDS within contemporary South African contexts.

    Needle electromyography (EMG) of the diaphragm carries the potential risk of pneumothorax. Knowing the approximate depth of the diaphragm should increase the test's safety and accuracy. Distances from the skin to the diaphragm and from the outer surface of the rib to the diaphragm were measured using B mode ultrasound in 150 normal subjects. When measured at the lower intercostal spaces, diaphragm depth varied between 0.78 and 4.91 cm beneath the skin surface and between 0.25 and 1.48 cm below the outer surface of the rib. Using linear regression modeling, body mass index (BMI) could be used to predict diaphragm depth from the skin to within an average of 1.15 mm. Diaphragm depth from the skin can vary by more than 4 cm. When image guidance is not available to enhance accuracy and safety of diaphragm EMG, it is possible to reliably predict the depth of the diaphragm based on BMI.

    Incorporating geophysical technologies into forensic investigations has become a growing practice. Oftentimes, forensic professionals rely on basic metal detectors to assist their efforts during metallic weapons searches. This has created a need for controlled research in the area of weapons searches, specifically to formulate guidelines for geophysical methods that may be appropriate for locating weapons that have been discarded or buried by criminals attempting to conceal their involvement in a crime. Controlled research allows not only for testing of geophysical equipment, but also for updating search methodologies. This research project was designed to demonstrate the utility of an all-metal detector for locating a buried metallic weapon through detecting and identifying specific types of buried metal targets. Controlled testing of 32 buried targets which represented a variety of sizes and metallic compositions included 16 decommissioned street-level firearms, 6 pieces of assorted scrap metals, and 10 blunt or bladed weapons. While all forensic targets included in the project were detected with the basic all-metal detector, the size of the weapon and surface area were the two variables that affected maximum depth of detection, particularly with the firearm sample. For example, when using a High setting the largest firearms were detected at a maximum depth of 55 cm, but the majority of the remaining targets were only detected at a maximum depth of 40 cm or less. Overall, the all-metal detector proved to be a very good general purpose metal detector best suited for detecting metallic items at shallow depths. 2009 Elsevier Ireland Ltd. All rights reserved.

    The ultimate goal of Picture Archiving and Communication System (PACS)-based Computer-Aided Detection and Diagnosis (CAD) is to integrate CAD results into daily clinical practice so that it becomes a second reader to aid the radiologist's diagnosis. Integration of CAD and Hospital Information System (HIS), Radiology Information System (RIS) or PACS requires certain basic ingredients from Health Level 7 (HL7) standard for textual data, Digital Imaging and Communications in Medicine (DICOM) standard for images, and Integrating the Healthcare Enterprise (IHE) workflow profiles in order to comply with the Health Insurance Portability and Accountability Act (HIPAA) requirements to be a healthcare information system. Among the DICOM standards and IHE workflow profiles, DICOM Structured Reporting (DICOM-SR); and IHE Key Image Note (KIN), Simple Image and Numeric Report (SINR) and Post-processing Work Flow (PWF) are utilized in CAD-HIS/RIS/PACS integration. These topics with examples are presented in this chapter.

    It is well demonstrated that adequate burns first aid treatment (BFAT) improves clinical outcomes for the injured but adequacy remains low in many studies. This study presents a twelve month assessment of the adequacy of burns first aid treatment for patients managed by the Burns Service, Royal Darwin Hospital (RDH). Prospective study design of all patients managed by the Burns Service, Royal Darwin Hospital. Data were collated from two sources; RDH Burns Registry, and the Burns Registry of Australia and New Zealand (BRANZ). Inclusion criterion was all patients managed by the Burns Service, Royal Darwin Hospital for the period 1 January 2014-31 December 2014. Variables collected and analysed include: demographics, burn mechanism, burn wound depth and adequacy of and circumstances around first aid. Overall 310 cases were analysed. Most injuries involved adults (68%), 19% Indigenous persons and 70% of all patients had their burn injury occur in the urban region. Adequate BFAT occurred in 41% of cases. Adults, contact burns and those where the burn injury occurred in the remote regions were less likely to receive adequate BFAT. Indigenous persons were less likely to attempt any BFAT at all and when they did receive BFAT it was more likely applied by an emergency responder or health professional. Overall adequacy of BFAT is low in the Top End of the Northern Territory. Remote dwellers and Indigenous persons are at increased risk of not applying or receiving adequate BFAT. The poor level of adequate BFAT demonstrated in this study suggests that the Top End community particularly remote and Indigenous persons would benefit from targeted BFAT education programs that are delivered in a culturally and linguistically appropriate fashion.

    AIDS in Africa is killing more people than all of Africa's armed conflicts during this century--this is what delegates heard at the 11th International Conference on AIDS and STDs in Lusaka, Zambia, September 12-16, 1999. The epidemic has been contained in the rich Northern Hemisphere. But why the difference? Delegates considered many reasons, such as war, crumbling health infrastructure, increasing unemployment, and poverty. The conference concentrated on the impact of HIV/AIDS on communities, and on socioeconomic, ethical, political, and legal factors. Only one of the five sessions was devoted to basic science and clinical care. There was realism concerning the limited role of antiretroviral therapy and excitement concerning improved prevention of parent-to-child transmission, especially if single-dose nevirapine proves effective. Delegates emphasized the need for more research and development of vaccines, the female condom, and vaginal virucides, all of which are commercially unattractive to drug companies. Callisto Medavo, World Bank vice-president, launched ACT-Africa, which promises extra resources, enhanced treatment, and more technical support. Together these should assist African leaders and mobilize civil society and the private sector to intensify action against HIV/AIDS. Peter Piot, executive director of UNAIDS, also emphasized the vital importance of sustained political involvement at the highest level to contain the pandemic and prevent this regional crisis from becoming a global catastrophe.

  19. Strong-field Photoionization of Sputtered Neutral Molecules for Molecular Depth Profiling

    2009-01-01

    Molecular depth profiles of an organic thin film of guanine vapor deposited onto a Ag substrate are obtained using a 40 keV C60 cluster ion beam in conjunction with time-of-flight secondary ion mass spectrometric (ToF-SIMS) detection. Strong-field, femtosecond photoionization of intact guanine molecules is used to probe the neutral component of the profile for direct comparison with the secondary ion component. The ability to simultaneously acquire secondary ions and photoionized neutral molecules reveals new fundamental information about the factors that influence the properties of the depth profile. Results show that there is an increased ionization probability for protonated molecular ions within the first 10 nm due to the generation of free protons within the sample. Moreover, there is a 50% increase in fragment ion signal relative to steady state values 25 nm before reaching the guanine/Ag interface as a result of interfacial chemical damage accumulation. An altered layer thickness of 20 nm is observed as a consequence of ion beam induced chemical mixing. In general, we show that the neutral component of a molecular depth profile using the strong-field photoionization technique can be used to elucidate the effects of variations in ionization probability on the yield of molecular ions as well as to aid in obtaining accurate information about depth dependent chemical composition that cannot be extracted from TOF-SIMS data alone.

    To present a multi-centre study that analyses the socioeconomic, cultural and political contexts that give rise to population mobility, and its relationship to vulnerability to sexually transmitted infections (STI)/HIV/AIDS, in order to provide information that can be used to design appropriate and focused interventions. In each of 11 transit stations (border towns, port cities, areas where mobile populations congregate) in Central America and Mexico, a household survey of the local population was conducted to analyse demographic, socioeconomic characteristics, and information known and opinions held about HIV/AIDS and mobile populations. In-depth interviews with key informants, community members and mobile populations were held to ascertain knowledge about prevention and transmission of STI/HIV/AIDS. Likewise, an ethnographic study was undertaken to identify interactions between local and mobile populations. The transit stations share low educational levels among the local population, few public services, repeated human rights violations, violence, poverty and corrupt authorities. Within this social context, transactional sex, sex for survival, rape and non-professional commercial sex happen in conditions that increase the risk of the transmission of STI/HIV, such as infrequent condom use. Migrant women and sex workers are particularly vulnerable in this context. A wide gap exists between information about STI/HIV transmission and reported prevention practices. Given the conditions that exist in these transit stations, interventions should be multisectoral, sustainable, and should defend the human rights of various groups, including women and people living with HIV/AIDS.

  1. Mismatch repair defects and Lynch syndrome: The role of the basic scientist in the battle against cancer.

    PubMed

    Heinen, Christopher D

    2016-02-01

    We have currently entered a genomic era of cancer research which may soon lead to a genomic era of cancer treatment. Patient DNA sequencing information may lead to a personalized approach to managing an individual's cancer as well as future cancer risk. The success of this approach, however, begins not necessarily in the clinician's office, but rather at the laboratory bench of the basic scientist. The basic scientist plays a critical role since the DNA sequencing information is of limited use unless one knows the function of the gene that is altered and the manner by which a sequence alteration affects that function. The role of basic science research in aiding the clinical management of a disease is perhaps best exemplified by considering the case of Lynch syndrome, a hereditary disease that predisposes patients to colorectal and other cancers. This review will examine how the diagnosis, treatment and even prevention of Lynch syndrome-associated cancers has benefitted from extensive basic science research on the DNA mismatch repair genes whose alteration underlies this condition.

    Human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) are among the most complex health problems in the world. Young people are at high risk of HIV and AIDS infections and are, therefore, in need of targeted prevention. School-based HIV/AIDS health education may be an effective way to prevent the spread of AIDS among adolescents. The study was a school-based intervention conducted in three middle schools and two high schools in Wuhan, China, which included 702 boys and 766 girls, with ages from 11 to 18 years old. The intervention was a one-class education program about HIV/AIDS for participants. HIV/AIDS knowledge, attitude, and high-risk behaviors were investigated using an anonymous self-administered questionnaire before and after the education intervention. Chi-square test was used to compare differences before and after the intervention. Non-conditional logistic regression analysis was used to identify the factors that affect HIV/AIDS knowledge. Misconceptions about basic medical knowledge and non-transmission modes of HIV/AIDS among all the students prevail. Approximately 10% to 40% of students had negative attitudes about HIV/AIDS before the intervention. After the intervention, all of the students had significant improvements in knowledge and attitude about HIV/AIDS (P<.05), indicating that educational intervention increased the students' knowledge significantly and changed their attitudes positively. Logistic regression analyses indicated that before the intervention the students' level of knowledge about HIV/AIDS was significantly associated with grade, economic status of the family, and attitudes toward participation in HIV/AIDS health information campaigns. HIV/AIDS education programs were welcomed by secondary students and positively influenced HIV/AIDS-related knowledge and attitudes. A systematic and long-term intervention among secondary school students must be conducted for the prevention of HIV.

    Purpose of the Study: Aging and HIV/AIDS research focuses primarily on standardized clinical, social, and behavioral measures, leaving unanswered questions about how this chronic and stigmatizing condition affects life course expectations and the meaning of aging with the disease. Utilizing Gaylene Becker’s (1997) life course disruption theory, we explored older African Americans’ experiences of living with HIV/AIDS. Design and Methods: A purposive sample (N = 43) of seropositive African Americans aged 50 and older was selected from a parent study. Thirteen participants completed one semi-structured in-depth interview on life course expectations and experiences of living with HIV/AIDS. Interview transcripts were analyzed using standard qualitative coding and thematic analysis. Results: Responding to broad, open-ended questions about the impact of HIV on life course expectations, participants emphasized how HIV limited their ability to experience sexuality and intimacy. Two major themes emerged, damaged sexuality and constrained intimacy. Implications: Older African Americans’ discussions of living with HIV focused on the importance of and the challenges to sexuality and intimacy. Researchers and clinicians should be attentive to significant and ongoing HIV-related challenges to sexuality and intimacy facing older African Americans living with HIV/AIDS. PMID:26035889

    Hearing loss can result from disorders or damage to the ear (peripheral auditory system) or the brain (central auditory system). Here, the basic structure and function of the central auditory system will be highlighted as relevant to cases of permanent hearing loss where assistive devices (hearing aids) are called for. The parts of the brain used for hearing are altered in two basic ways in instances of hearing loss: (1) Damage to the ear can reduce the number and nature of input channels that the brainstem receives from the ear, causing plasticity of the central auditory system. This plasticity may partially compensate for the peripheral loss, or add new abnormalities such as distorted speech processing or tinnitus. (2) In some situations, damage to the brain can occur independently of the ear, as may occur in cases of head trauma, tumors or aging. Implications of deficits to the central auditory system for speech perception in noise, hearing aid use and future innovative circuit designs will be provided to set the stage for subsequent presentations in this special educational session.

    Sexual transmission of HIV/AIDS among women is growing in the Middle East region. Despite the fact that there are numerous gender-related sociocultural factors influencing HIV/AIDS protective behaviors, little gender-specificity is carried out in HIV prevention in Iran. In order to close this gap, we aimed to provide preliminary work that explored the perceptions that women at risk of HIV had about gender norms and gendered power and their ability to protect themselves against HIV/AIDS. Twenty-five semi-structured in-depth interviews were conducted with women at risk of HIV/AIDS, aged 21-49 years, at Voluntary Counseling and Testing Centers or Drop in Centers in Tehran, Iran. Results showed that perceived gender norms were essential barriers of protective behavior through sexual socialization, male control over condom use and sexual decision-making, male pleasure predominating in sexual encounters and sexual double standards, and economic dependencies. In the conclusions, we consider how HIV/AIDS preventive programs can be structured to be gender-sensitive and empowering in Iran.

    We demonstrate depth-resolved imaging in a ballistic imaging system, in which a heterodyned femtosecond optical Kerr gate is introduced to extract useful imaging photons for detecting an object hidden in turbid media and a compound lens is proposed to ensure both the depth-resolved imaging capability and the long working distance. Two objects of about 15-μm widths hidden in a polystyrene-sphere suspension have been successfully imaged with approximately 600-μm depth resolution. Modulation-transfer-function curves with the object in and away from the object plane have also been measured to confirm the depth-resolved imaging capability of the low-depth-of-field (low-DOF) ballistic imaging system. This imaging approach shows potential for application in research of the internal structure of highly scattering fuel spray.

  8. Islamic perspectives on HIV/AIDS and antiretroviral treatment: the case of Nigeria.

    2010-12-01

    Some religious reactions to the HIV epidemic in Africa unwittingly contributed to the expansion of the epidemic in its early years. This was because many religious people regarded the emergence of HIV and AIDS as divine punishment for man's sins as a result of people's sexual promiscuity. Some also opposed public promotion of the use of condoms for HIV prevention. However, religious bodies have made positive contributions to HIV/AIDS responses in many African countries in recent times. Though Christian bodies are taking the lead in faith-based responses to HIV and AIDS in Africa, Islamic bodies have also been major partners in HIV/AIDS interventions in several countries. Against this background, this article examines some Islamic perceptions of HIV and AIDS, and especially the impact of antiretroviral treatment (ART) for people living with HIV in Africa, with particular emphasis on Nigeria. In spite of the emergence of antiretroviral (ARV) drugs in Africa, Islam still emphasises the prevention of new infections and care for people living with HIV or AIDS. The article discusses basic issues associated with ARVs, such as health, sickness, life-prolongation and death, from an Islamic viewpoint, as well as some Islamic measures to prevent HIV-risk-taking behaviours in an era of ARVs. It also looks at the nature and extent of Islamic involvement in the national HIV/AIDS response in Nigeria. The paper concludes that while Islam sees HIV and AIDS and other diseases as 'tests' from Allah, the religion is not opposed to ART. Thus, efforts need to be intensified by Islamic bodies and Muslim leaders in Nigeria for an improved response to HIV and AIDS in the country.

    The human rights organization Americas Watch, which toured Mexican prisons, reported in 1991 that all prisoners with HIV infection in the Mexico City area were housed in a single AIDS ward in Santa Marta Prison. In 1991, the 16-bed facility had 15 patients; in 1993, this number had increased by 5. In Mexico City, with 3 prisons holding over 2000 male adults each, there were only 20 known infected prisoners in the AIDS ward at Santa Marta. In 1991, authorities at Matamoros, in the state of Tamaulipas, insisted that none of their inmates had ever been diagnosed as infected with HIV. The prison physician at Reynosa indicated that only 2 inmates since 1985 had ever been diagnosed as infected. In 1992, the prison in Saltillo, in the state of Coahuila, reported that here had yet to be a single positive test for HIV. The prison at Reynosa held 1500 people and only 2 inmates were diagnosed as having AIDS between 1985 and 1991. Prisons at Matamoros and Saltillo held similar numbers but had no experience of infected inmates. A survey of 2 prisons in the state of Tamaulipas indicates that around 12% of the population may use IV drugs, and 9% indicate sharing needles. It is possible for prisoners to die of diseases like pneumonia, associated with AIDS, without the connection to AIDS being diagnosed. Each state, and possibly each prison in Mexico, has its own particular AIDS policies. Santa Marta was the single facility in Mexico City used to house AIDS-infected prisoners, who were segregated. Finally, the prison at Saltillo required all women entering the facility to have a medical examination, including a test for HIV. High-level prison personnel have demonstrated ignorance and fear of AIDS and intolerance of infected prisoners. Mexico must reassess the need to provide adequate medical care to offenders who are sick and dying behind bars.

  10. Theodore E. Woodward Award. HIV/AIDS, ethics, and medical professionalism: where went the debate?

    PubMed Central

    Bryan, Charles S.

    2003-01-01

    The recent surge of dialogue about medical professionalism has largely ignored HIV/AIDS, perhaps because the ethical issues that abounded during the 1980s and early 1990s have become largely passé. Prior to the introduction of highly active antiretroviral therapy (HAART) in 1996, the care ethic for patients with HIV/AIDS depended heavily on compassion since effective treatment was unavailable. Moreover, physicians and other health care workers often assumed physical risks on behalf of patients. HAART transformed the care ethic for HIV/AIDS to one dependent mainly on medical competence. Reflecting on the epidemic, I propose a distinction between "basic" and "higher" professionalism. Basic professionalism requires discipline-specific competence, facilitated by adherence to the four cardinal virtues (prudence, temperance, justice, and courage). Higher professionalism brings into play the transcendent virtues: faith, hope, and--especially--love (compassion). Specific examples of "compassion" in the strict sense of "suffering with" include caring without adequate reimbursement, caring when one would rather be doing something else, and assuming emotional or physical risks on behalf of patients. The physicians and other health care workers who displayed such compassion in abundance between 1981 and 1996 deserve our remembrance as exemplars of a higher professionalism. PMID:12813930

  14. We are all people living with AIDS: myths and realities of AIDS in Brazil.

    PubMed

    Daniel, H

    1991-01-01

    Although AIDS was expected in Brazil, no serious efforts were undertaken to prevent AIDS from taking root. Irresponsible press and media coverage highlighted the spread of AIDS within the gay community of the United States, creating an aura of immunity in Brazil to what was characterized as a "foreign" disorder. When AIDS did surface in 1983, the official response was to adopt an abstract, inappropriate, and ideological "Western" model, in which only stigmatized "others" and "minorities" were at risk of HIV infection. Brazilian health authorities subsequently downplayed the significance of the sale of contaminated blood in HIV transmission, and likewise ignored the rising rates of AIDS among Brazil's one unarguable majority group: the poor. An analysis of efforts to force the "facts" of AIDS to fit a false model's predictions leads to a clearer definition of the broader context of the Brazilian epidemic: we all are people living with AIDS, precisely because we live in this age of AIDS; it is sheer folly to discriminate against persons infected by HIV and to obstruct their participation in efforts to curtail the epidemic's spread; and the necessary response to AIDS is solidarity, not because it is poetic, but because no other response will suffice.

    The complexity of providing healthcare to people with HIV/Aids requires investment in comprehensive action and care, constituting a challenge for the multidisciplinary work teams to build an interdisciplinary practice. This study sought to analyze comprehensive healthcare in the Specialized Assistance Services for HIV/Aids (SAE-HIV/Aids) in Recife, in the State of Pernambuco, starting with the process and organization of team work. This is a case study developed in three SAE-HIV/Aids units, based on a qualitative approach using different research techniques. The results show that SAE-HIV/Aids have complied with most of the Brazilian Health Ministry recommendations in terms of basic infrastructure, though none of them had a team of appropriate size. These services have shown signs of fragmentation and difficulty in establishing a systematic intersectorial and interdisciplinary practice, with failings in ensuring the reference and counter-reference flow. It was seen that there was little appreciation of the role of the manager as team leader. The need to perceive the user as a whole was identified, as well as for the team to work in a coordinated manner in order to ensure communicative and relational activities.

    The depth at which plants are able to grow roots has important implications for the whole ecosystem hydrological balance, as well as for carbon and nutrient cycling. Here we summarize what we know about the maximum rooting depth of species belonging to the major terrestrial biomes. We found 290 observations of maximum rooting depth in the literature which covered 253 woody and herbaceous species. Maximum rooting depth ranged from 0.3 m for some tundra species to 68 m for Boscia albitrunca in the central Kalahari; 194 species had roots at least 2 m deep, 50 species had roots at a depth of 5 m or more, and 22 species had roots as deep as 10 m or more. The average for the globe was 4.6±0.5 m. Maximum rooting depth by biome was 2.0±0.3 m for boreal forest. 2.1±0.2 m for cropland, 9.5±2.4 m for desert, 5.2±0.8 m for sclerophyllous shrubland and forest, 3.9±0.4 m for temperate coniferous forest, 2.9±0.2 m for temperate deciduous forest, 2.6±0.2 m for temperate grassland, 3.7±0.5 m for tropical deciduous forest, 7.3±2.8 m for tropical evergreen forest, 15.0±5.4 m for tropical grassland/savanna, and 0.5±0.1 m for tundra. Grouping all the species across biomes (except croplands) by three basic functional groups: trees, shrubs, and herbaceous plants, the maximum rooting depth was 7.0±1.2 m for trees, 5.1±0.8 m for shrubs, and 2.6±0.1 m for herbaceous plants. These data show that deep root habits are quite common in woody and herbaceous species across most of the terrestrial biomes, far deeper than the traditional view has held up to now. This finding has important implications for a better understanding of ecosystem function and its application in developing ecosystem models.

  17. Local Stability of AIDS Epidemic Model Through Treatment and Vertical Transmission with Time Delay

    This study aims to explain stability of the spread of AIDS through treatment and vertical transmission model. Human with HIV need a time to positively suffer AIDS. The existence of a time, human with HIV until positively suffer AIDS can be delayed for a time so that the model acquired is the model with time delay. The model form is a nonlinear differential equation with time delay, SIPTA (susceptible-infected-pre AIDS-treatment-AIDS). Based on SIPTA model analysis results the disease free equilibrium point and the endemic equilibrium point. The disease free equilibrium point with and without time delay are local asymptotically stable if the basic reproduction number is less than one. The endemic equilibrium point will be local asymptotically stable if the time delay is less than the critical value of delay, unstable if the time delay is more than the critical value of delay, and bifurcation occurs if the time delay is equal to the critical value of delay.

  18. Applications of just-noticeable depth difference model in joint multiview video plus depth coding

    A new multiview just-noticeable-depth-difference(MJNDD) Model is presented and applied to compress the joint multiview video plus depth. Many video coding algorithms remove spatial and temporal redundancies and statistical redundancies but they are not capable of removing the perceptual redundancies. Since the final receptor of video is the human eyes, we can remove the perception redundancy to gain higher compression efficiency according to the properties of human visual system (HVS). Traditional just-noticeable-distortion (JND) model in pixel domain contains luminance contrast and spatial-temporal masking effects, which describes the perception redundancy quantitatively. Whereas HVS is very sensitive to depth information, a new multiview-just-noticeable-depth-difference(MJNDD) model is proposed by combining traditional JND model with just-noticeable-depth-difference (JNDD) model. The texture video is divided into background and foreground areas using depth information. Then different JND threshold values are assigned to these two parts. Later the MJNDD model is utilized to encode the texture video on JMVC. When encoding the depth video, JNDD model is applied to remove the block artifacts and protect the edges. Then we use VSRS3.5 (View Synthesis Reference Software) to generate the intermediate views. Experimental results show that our model can endure more noise and the compression efficiency is improved by 25.29 percent at average and by 54.06 percent at most compared to JMVC while maintaining the subject quality. Hence it can gain high compress ratio and low bit rate.

    We incorporate basic genetics into an AIDS model. We illustrate that if a homozygote is immune to the disease or is resistant to the effects of the disease, the corresponding allele goes to fixation. On the other hand, if the heterozygote is immune to the disease or is resistant to the effects of the disease, polymorphism usually occurs.

  2. Myths about AIDS in Cambodia.

    PubMed

    Nariddh, M C

    1994-08-01

    HIV has been reported in the capital city of Cambodia, Phnom Penh, as well as in the northwestern provinces of Banteay Meanchey, Battambang, Pursat, and Kompong Chhnang. Unofficial reports indicate the presence of HIV in three northeastern provinces. According to World Health Organization data, 382 people were infected with HIV in Cambodia as of March 1994, but the national AIDS program estimates that 2000-4000 Cambodians may be HIV-seropositive. Small surveys in 1992 identified HIV infection rates to be 4.5% among patients of sexually transmitted disease (STD) clinics and 9.2% among prostitutes. A seroprevalence rate of 4.3% was found in 1993 among clients of STD clinics and others requesting HIV testing. These rather marked levels of infection exist in Cambodia even though HIV was first identified in the country as recently as 1991 among screened blood from volunteer donors. By December 1993, the rate of positive results from blood donors had increased to 1.97%.; the rate of infection among blood donors is expected to double to approximately 4% in 1994. People in Cambodia variously believe that AIDS is nonexistent, AIDS is a problem of other countries, can be transmitted by mosquitoes, healthy people do not have AIDS, a cure exists for AIDS, AIDS can be contracted only from prostitutes, AIDS is the most severe state of syphilis, and AIDS is only a propaganda ploy of condom producers to market their products. It is therefore proving extremely difficult to convince people that AIDS is a truly threatening disease against which they should protect themselves, especially when symptoms are rarely present during the early stage of infection. Health education campaigns, videos, posters, and accurate reporting in the media will, however, help change minds and hopefully induce HIV-preventive behaviors. Of interest, the article notes that virtually every prostitute in Cambodia has at least two-three STDs.

  3. Establishing evidence-informed core intervention competencies in psychological first aid for public health personnel.

    PubMed

    2006-01-01

    A full-scale public health response to disasters must attend to both the physical and mental health needs of affected communities. Public health preparedness efforts can be greatly expanded to address the latter set of needs, particularly in light of the high ratio of psychological to physical casualties that often rapidly overwhelms existing mental health response resources in a large-scale emergency. Psychological first aid--the provision of basic psychological care in the short term aftermath of a traumatic event--is a mental health response skill set that public health personnel can readily acquire with proper training. The application of psychological first aid by public health workers can significantly augment front-line community-based mental health responses during the crisis phase of an event. To help achieve this augmented response, we have developed a set of psychological first aid intervention competencies for public health personnel. These competencies, empirically grounded and based on best practice models and consensus statements from leading mental health organizations, represent a necessary step for developing a public health workforce that can better respond to the psychological needs of impacted populations in disasters.

  4. Stereoscopic depth constancy

    2016-01-01

    Depth constancy is the ability to perceive a fixed depth interval in the world as constant despite changes in viewing distance and the spatial scale of depth variation. It is well known that the spatial frequency of depth variation has a large effect on threshold. In the first experiment, we determined that the visual system compensates for this differential sensitivity when the change in disparity is suprathreshold, thereby attaining constancy similar to contrast constancy in the luminance domain. In a second experiment, we examined the ability to perceive constant depth when the spatial frequency and viewing distance both changed. To attain constancy in this situation, the visual system has to estimate distance. We investigated this ability when vergence, accommodation and vertical disparity are all presented accurately and therefore provided veridical information about viewing distance. We found that constancy is nearly complete across changes in viewing distance. Depth constancy is most complete when the scale of the depth relief is constant in the world rather than when it is constant in angular units at the retina. These results bear on the efficacy of algorithms for creating stereo content. This article is part of the themed issue ‘Vision in our three-dimensional world’. PMID:27269596

    2015-11-01

    Worldwide, there is a consensus that parents must be involved in children's HIV/AIDS education. However, there is little evidence that speaks to this advocacy for improving adolescent health. This study developed and tested four hypotheses about (i) the relationship between parents' and adolescents' knowledge of HIV/AIDS transmission routes and prevention strategies conditional upon (ii) parents' gender, (iii) communication about sexuality, and (iv) the parent-adolescent education gap. The sample consisted of 306 parent-adolescent dyads from the 2002 Cameroon Family and Health Survey. Adolescents were aged 12-19 years. Overall, fifteen items about HIV/AIDS transmission routes and prevention strategies were analysed. Descriptive results showed that parents fared better than adolescents regardless of the AIDS fact considered. An exception was the correct use of condoms (parents 57% vs adolescents 61%). The generation gap probably explains this result: parents are more conservative, reluctant and distant from condoms compared with adolescents, who are more receptive and open to discussing sex with peers. Multivariate ordered logistic regressions showed a significant positive effect of parents' HIV/AIDS knowledge on adolescents' HIV/AIDS knowledge, thus supporting the main hypothesis of direct parental influences. Parent-adolescent communication about sexuality showed positive and significant effects on adolescents' HIV/AIDS knowledge, suggesting an 'enhancing effect' when combined with the effect of parents' HIV/AIDS knowledge. Against the background that parents in sub-Saharan Africa do not teach their children about sexuality, the study demonstrated that families can play an important role in HIV/AIDS education. These findings have major implications for HIV/AIDS interventions involving adolescents, parents or both, in fostering accurate HIV/AIDS knowledge among adolescents, which could lead to protective sexual behaviours.

    The Defence Research Establishment Valcartier has initiated in 1998 R&D work to investigate and to demonstrate key technologies required for future Defensive Aid Suite to protect Light Armoured Vehicles. A basic Defensive Aid Suite demonstrator (Phase I) was built and integrated into the LAV vetronics by Litton Systems Canada and his consortium. The Defensive Aid Suite consisted of a 2-band HARLIDTM-based laser detection head, a processor capable to control and deploy countermeasures and a DAS touch-screen display all integrated in a Light Armored Vehicle. The crew was able to select the operation mode for direct fire or smoke deployment by pushing one of the pair of buttons available at the bottom of the display. This system was successfully demonstrated in October 1999 during an international trial. This article gives an overview of the results obtained in the field as well as some of the lessons learnt. It also describes laboratory and field measurements made on the Laser Warning Receiver unit itself. The results of the DAS tactical use and of Human factor evaluation will illustrate its performance within typical laser threat scenarios. This work will serve as the basis for the recommendation of a future DAS demonstrator (Phase II) integrating more sensors and countermeasures.

    Introduction HIV/AIDS has been one of the world’s most important health challenges in recent history. The global solidarity in responding to HIV/AIDS through the provision of antiretroviral therapy (ART) and encouraging early screening has been proved successful in saving lives of infected populations in past decades. However, there remain several challenges, one of which is how HIV/AIDS policies keep pace with the growing speed and diversity of migration flows. This study therefore aimed to examine the nature and the extent of HIV/AIDS health services, barriers to care, and epidemic burdens among cross-country migrants in low-and middle-income countries. Methods A scoping review was undertaken by gathering evidence from electronic databases and gray literature from the websites of relevant international initiatives. The articles were reviewed according to the defined themes: epidemic burdens of HIV/AIDS, barriers to health services and HIV/AIDS risks, and the operational management of the current health systems for HIV/AIDS. Results Of the 437 articles selected for an initial screening, 35 were read in full and mapped with the defined research questions. A high HIV/AIDS infection rate was a major concern among cross-country migrants in many regions, in particular sub-Saharan Africa. Despite a large number of studies reported in Africa, fewer studies were found in Asia and Latin America. Barriers of access to HIV/AIDS services comprised inadequate management of guidelines and referral systems, discriminatory attitudes, language differences, unstable legal status, and financial hardship. Though health systems management varied across countries, international partners consistently played a critical role in providing support for HIV/AIDS services to uninsured migrants and refugees. Conclusion It was evident that HIV/AIDS health care problems for migrants were a major concern in many developing nations. However, there was little evidence suggesting if the current

  12. Epigenetic regulation of HIV, AIDS, and AIDS-related malignancies.

    PubMed

    Verma, Mukesh

    2015-01-01

    Although epigenetics is not a new field, its implications for acquired immunodeficiency syndrome (AIDS) research have not been explored fully. To develop therapeutic and preventive approaches against the human immunodeficiency virus (HIV) and AIDS, it is essential to understand the mechanisms of interaction between the virus and the host, involvement of genetic and epigenetic mechanisms, characterization of viral reservoirs, and factors influencing the latency of the virus. Both methylation of viral genes and histone modifications contribute to initiating and maintaining latency and, depending on the context, triggering viral gene repression or expression. This chapter discusses progress made at the National Institutes of Health (NIH), recommendations from the International AIDS Society Scientific Working Group on HIV Cure, and underlying epigenetic regulation. A number of epigenetic inhibitors have shown potential in treating AIDS-related malignancies. Epigenetic drugs approved by the US Food and Drug Administration and their implications for the eradication of HIV/AIDS and AIDS-related malignancies also are discussed.Past and current progress in developing treatments and understanding the molecular mechanisms of AIDS and HIV infection has greatly improved patient survival. However, increased survival has been coupled with the development of cancer at higher rates than those observed among the HIV/AIDS-negative population. During the early days of the AIDS epidemic, the most frequent AIDS-defining malignancies were Kaposi's sarcoma and non-Hodgkin lymphoma (NHL). Now, with increased survival as the result of widespread use in the developed world of highly active antiretroviral therapy (HAART), non-AIDS defining cancers (i.e., anal, skin, and lung cancers, and Hodgkin disease) are on the increase in HIV-infected populations. The current status of AIDS-related malignancies also is discussed.

  13. Cost of oviposition site selection in a water strider Aquarius paludum insularis: egg mortality increases with oviposition depth.

    2010-06-01

    Females generally avoid selecting sites for oviposition which have a high predation risk to increase offspring survival. Previous studies have focused on costs to ovipositing females. However, although offspring may also incur costs by being oviposited at low predation risk sites, no studies have focused on costs to offspring. Such costs to offspring were examined by using Aquarius paludum insularis, females of which avoid eggs parasitism by ovipositing at deep sites. Deep sites are safe from egg parasitism but may be unsuitable for hatching due to environmental factors. We examined the costs to offspring at deep sites by comparing the hatching rate, the duration to hatching and the proportion of drowned larvae between eggs that were set at three levels of water depth (0 cm, 25 cm and 50 cm depth). While the hatching rate at 50 cm was lower than that at 0 cm, the rate at 25 cm did not differ from that at 0 cm. Duration to hatching and the proportion of drowned larvae did not differ between the three depths. It is suggested that the declining survival rate of A. paludum eggs was due to increased water pressure at greater depth. Such a cost may exist in other species and such an observation may aid in understanding oviposition site selection. Copyright 2010 Elsevier Ltd. All rights reserved.

    1996-10-01

    Professional health care workers have access to guidelines, equipment and techniques to reduce the exposure to infectious material in case of resuscitation. The current official content of national courses for volunteer life-savers do not address this issue, as far as we know. Concern about the risks of infection due to resuscitation is increasing in this group. This article describes a rational approach of the problem, that includes data on the infection risk of basic-CPR, and an approach that accepts that the concern can not be controlled by objective data. In such an emotional approach, direct contact has to be minimised by using devices. Requirements for resuscitation devices with a barrier function are listed. Although both approaches will reduce the fear of infection, we advice a rational approach.

    The specter of pediatric AIDS fundamentally challenges elements of the liberal ideological basis of women's reproductive freedom. Many public health officials hold that preventing transmission of HIV from mother to fetus requires efforts to discourage pregnancy by infected women. For over two decades, however, genetic counselors, feminists, and medical ethicists have stressed the importance of nondirective counseling in the context of reproductive choice. The question now confronted by American society is whether it will be possible to frame an ideology of reproductive choice that recognizes the limits of liberal individualism, while preserving the basic features of reproductive freedom.

    This study aimed to compare the effectiveness of tinnitus retraining therapy (TRT) with sound generators or with open ear hearing aids in the rehabilitation of tinnitus for a group of subjects who, according to Jastreboff categories, can be treated with both approaches to sound therapy (borderline of Category 1 and 2). This study was a prospective data collection with a parallel-group design which entailed that each subject was randomly assigned to one of the two treatments group: half of the subjects were fitted binaurally with sound generators, and the other half with open ear hearing aids. Both groups received the same educational counselling sessions. Ninety-one subjects passed the screening criteria and were enrolled into the study. Structured interviews, with a variety of measures evaluated through the use of visual-analog scales and the tinnitus handicap inventory self-administered questionnaire, were performed before the therapy and at 3, 6, and 12 months during the therapy. Data showed a highly significant improvement in both tinnitus treatments starting from the first three months and up to one year of therapy, with a progressive and statistically significant decrease in the disability every three months. TRT was equally effective with sound generator or open ear hearing aids: they gave basically identical, statistically indistinguishable results.

    A tablet computer with a depth camera and a color camera is loaded on a traditional shopping cart. The inside information of the shopping cart is obtained by two cameras. In the shopping cart monitoring field, it is very important for us to determine whether the customer with goods in or out of the shopping cart. This paper establishes a basic framework for judging empty hand, it includes the hand extraction process based on the depth information, process of skin color model building based on WPCA (Weighted Principal Component Analysis), an algorithm for judging handheld products based on motion and skin color information, statistical process. Through this framework, the first step can ensure the integrity of the hand information, and effectively avoids the influence of sleeve and other debris, the second step can accurately extract skin color and eliminate the similar color interference, light has little effect on its results, it has the advantages of fast computation speed and high efficiency, and the third step has the advantage of greatly reducing the noise interference and improving the accuracy.

  19. Z-depth integration: a new technique for manipulating z-depth properties in composited scenes

    NASA Astrophysics Data System (ADS)

    Steckel, Kayla; Whittinghill, David

    2014-02-01

    This paper presents a new technique in the production pipeline of asset creation for virtual environments called Z-Depth Integration (ZeDI). ZeDI is intended to reduce the time required to place elements at the appropriate z-depth within a scene. Though ZeDI is intended for use primarily in two-dimensional scene composition, depth-dependent "flat" animated objects are often critical elements of augmented and virtual reality applications (AR/VR). ZeDI is derived from "deep image compositing", a capacity implemented within the OpenEXR file format. In order to trick the human eye into perceiving overlapping scene elements as being in front of or behind one another, the developer must manually manipulate which pixels of an element are visible in relation to other objects embedded within the environment's image sequence. ZeDI improves on this process by providing a means for interacting with procedurally extracted z-depth data from a virtual environment scene. By streamlining the process of defining objects' depth characteristics, it is expected that the time and energy required for developers to create compelling AR/VR scenes will be reduced. In the proof of concept presented in this manuscript, ZeDI is implemented for pre-rendered virtual scene construction via an AfterEffects software plug-in.

    A detailed feasibility study on the combined use of laser-induced breakdown spectroscopy with optical coherence tomography (LIBS/OCT), aiming at a realistic depth-resolved elemental analysis of multilayer stratigraphies in paintings, is presented. Merging a high spectral resolution LIBS system with a high spatial resolution spectral OCT instrument significantly enhances the quality and accuracy of stratigraphic analysis. First, OCT mapping is employed prior to LIBS analysis in order to assist the selection of specific areas of interest on the painting surface to be examined in detail. Then, intertwined with LIBS, the OCT instrument is used as a precise profilometer for the online determination of the depth of the ablation crater formed by individual laser pulses during LIBS depth-profile analysis. This approach is novel and enables (i) the precise in-depth scaling of elemental concentration profiles, and (ii) the recognition of layer boundaries by estimating the corresponding differences in material ablation rate. Additionally, the latter is supported, within the transparency of the object, by analysis of the OCT cross-sectional views. The potential of this method is illustrated by presenting results on the detailed analysis of the structure of an historic painting on canvas performed to aid planned restoration of the artwork.

    In the context of severe human resource shortages in HIV care, task-shifting and especially community-based support are increasingly being cited as potential means of providing durable care to chronic HIV patients. Socio-ecological theory clearly stipulates that–in all social interventions–the interrelatedness and interdependency between individuals and their immediate social contexts should be taken into account. People living with HIV/AIDS (PLWHA) seldom live in isolation, yet community-based interventions for supporting chronic HIV patients have largely ignored the social contexts in which they are implemented. Research is thus required to investigate such community-based support within its context. The aim of this study is to address this research gap by examining the way in which HIV/AIDS competence in the household hampers or facilitates community-based treatment adherence support. The data was analyzed carefully in accordance with the Grounded Theory procedures, using Nvivo 10. More specifically, we analyzed field notes from participatory observations conducted during 48 community-based treatment adherence support sessions in townships on the outskirts of Cape Town, transcripts of 32 audio-recorded in-depth interviews with PLWHA and transcripts of 4 focus group discussions with 36 community health workers (CHWs). Despite the fact that the CHWs try to present themselves as not being openly associated with HIV/AIDS services, results show that the presence of a CHW is often seen as a marker of the disease. Depending on the HIV/AIDS competence in the household, this association can challenge the patient’s hybrid identity management and his/her attempt to regulate the interference of the household in the disease management. The results deepen our understanding of how the degree of HIV/AIDS competence present in a PLWHA’s household affects the manner in which the CHW can perform his or her job and the associated benefits for the patient and his

    The global rapid growth in mobile technology provides unique opportunities to support community health workers (CHWs) in providing family planning (FP) services. FHI 360, Pathfinder International and D-tree International developed an evidence-based mobile job aid to support CHW counseling, screening, service provision and referrals, with mobile forms for client and service data, and text-message reporting and reminders. The purpose of this study is to evaluate the acceptability and potential benefits to service quality from the perspective of CHWs and their clients. The mobile job aid was piloted in Dar es Salaam, Tanzania. Data collection tools included a demographic survey of all 25 CHWs trained to use the mobile job aid, in-depth interviews with 20 of the CHWs after 3 months and a survey of 176 clients who received FP services from a CHW using the mobile job aid after 6 months. Both CHWs and their clients reported that the mobile job aid was a highly acceptable FP support tool. CHWs perceived benefits to service quality, including timelier and more convenient care; better quality of information; increased method choice; and improved privacy, confidentiality and trust with clients. Most clients discussed multiple FP methods with CHWs; only 1 in 10 clients reported discussion of all 9 methods. This research suggests that mobile phones can be effective tools to support CHWs with FP counseling, screening and referrals, data collection and reporting, and communication. Challenges remain to support informed contraceptive choice. Future research should focus on implementation, including scale-up and sustainability. Mobile job aids can uniquely enhance FP service provision at the community level through adherence to standard protocols, real-time feedback and technical assistance, and provision of confidential care. This study can inform future efforts to support and expand the role of CHWs in increasing FP access and informed contraceptive choice. Copyright © 2016

    The World Health Organization has announced that within 3 years 10% of Tanzania's population of 26 million will be infected with the human immunodeficiency virus (HIV). But there is some faint hope in the research of Tanzanian traditional medicine. An almost 90-year-man, Waziri Mrisho, is credited with having treated AIDS patients successfully with herbs that strengthen the immune system. Margaret Nakamya was stricken by the symptoms of AIDs in March 1990. She was referred to Waziri and started using his herbs. 3 years later she weighs 49 kg compared to 40 kg before. The old man's son set up a little factory where he pulverizes herbs and sells them at the price he can command The 3 types of trees that the herbal medicine is taken from grow in the wild, but some have also been planted around the factory. Even if these herbs are effective, it will take years before the AIDS epidemic is over, when people have changed their lifestyles. The means of communication (TV, cinema, radio, telephone) are missing or inadequate. In the Kagera region, with 1.2 million inhabitants, 25% of pregnant women are HIV-infected and 65,000 children lost their parents to AIDS. There are 2000 children in Dar Es Salaam living in the streets. The Anglican St. Albans Church runs a center for street kids where they get meals 3 times a week. The nurse Ruth Nesje enlisted a Norwegian physician and homeopath in a research project involving 30 AIDS patients in Norway. The University in Bergen will do in vitro testing. One group of patients will receive both AZT and the herbs, another group will get only AZT, and the 3rd group will obtain only the herbs. The Norwegian Nursing Association, NORAD, and DANIDA also plan various projects in the Tanga region.

  5. A Kirchhoff approach to seismic modeling and prestack depth migration

    The Kirchhoff integral provides a robust method for implementing seismic modeling and prestack depth migration, which can handle lateral velocity variation and turning waves. With a little extra computation cost, the Kirchoff-type migration can obtain multiple outputs that have the same phase but different amplitudes, compared with that of other migration methods. The ratio of these amplitudes is helpful in computing some quantities such as reflection angle. I develop a seismic modeling and prestack depth migration method based on the Kirchhoff integral, that handles both laterally variant velocity and a dip beyond 90 degrees. The method uses a finite-difference algorithm to calculate travel times and WKBJ amplitudes for the Kirchhoff integral. Compared to ray-tracing algorithms, the finite-difference algorithm gives an efficient implementation and single-valued quantities (first arrivals) on output. In my finite difference algorithm, the upwind scheme is used to calculate travel times, and the Crank-Nicolson scheme is used to calculate amplitudes. Moreover, interpolation is applied to save computation cost. The modeling and migration algorithms require a smooth velocity function. I develop a velocity-smoothing technique based on damped least-squares to aid in obtaining a successful migration.

    Aging and HIV/AIDS research focuses primarily on standardized clinical, social, and behavioral measures, leaving unanswered questions about how this chronic and stigmatizing condition affects life course expectations and the meaning of aging with the disease. Utilizing Gaylene Becker's (1997) life course disruption theory, we explored older African Americans' experiences of living with HIV/AIDS. A purposive sample (N = 43) of seropositive African Americans aged 50 and older was selected from a parent study. Thirteen participants completed one semi-structured in-depth interview on life course expectations and experiences of living with HIV/AIDS. Interview transcripts were analyzed using standard qualitative coding and thematic analysis. Responding to broad, open-ended questions about the impact of HIV on life course expectations, participants emphasized how HIV limited their ability to experience sexuality and intimacy. Two major themes emerged, damaged sexuality and constrained intimacy. Older African Americans' discussions of living with HIV focused on the importance of and the challenges to sexuality and intimacy. Researchers and clinicians should be attentive to significant and ongoing HIV-related challenges to sexuality and intimacy facing older African Americans living with HIV/AIDS. © The Author 2015.

    Device characteristics and hot-carrier-induced device degradation of n-channel MOS transistors with an off-state breakdown voltage of approximately 25 V and various Si recess depths introduced by sidewall spacer overetching are investigated. Experimental data show that the depth of the Si recess has small effects on device characteristics. A device with a deeper Si recess has lower substrate current and channel electric field, whereas a greater hot-carrier-induced device degradation and a shorter hot-carrier lifetime are observed. Results of technology computer-aided design simulations suggest that these unexpected observations are related to the severity of plasma damage caused by the sidewall spacer overetching and the difference in topology.

    To determine the involvement of cervical intraepithelial neoplasia grade 3 (CIN3) in a population of women in a lower-resource setting. One hundred twelve consecutive cone excision specimens with histological diagnosis of CIN3 were retrieved from the National Institute of Neoplastic Diseases in Lima Peru. Two pathologists independently evaluated each specimen microscopically and confirmed 107 cases that could be measured by optical micrometry. Depth and breadth of the lesions were measured microscopically. The mean maximal depth of cervical involvement by CIN3 was 2 ± 0.13 mm; depth was less than 3.5 mm in 89.7% of cases and less than 5 mm in 93.5%. Mean breadth of CIN3 was 7.3 ± 4.4 mm; breadth was less than 15.9 mm in 95% of cases and less than 20.5 mm in 99.7%. The correlation coefficient between breadth and depth of CIN3 was 0.61. No significant correlation was found between age and depth. Depth of CIN3 involvement in a developing country is significantly deeper than that reported in the United States. Treatment selection for women with CIN3 and risk of treatment failure may vary between developing and developed countries because of the difference in the depth of lesions. Countries with underscreened populations need to consider the increased disease severity in devising treatment strategies.

    Several studies have found reductions in acquired immunodeficiency syndrome (AIDS) risk practices among gay men in high AIDS-prevalence cities since the start of the AIDS crisis. Much less is known about risk behavior patterns among gay men in smaller cities, where AIDS cases are less common and the prevalence of human immunodeficiency virus infection is relatively lower. In the study, men entering gay bars in three cities, one large and two small, completed anonymous surveys of sexual practices and AIDS risk knowledge. Men in high AIDS-prevalence areas were found to have had a greater number of sexual partners, were more knowledgeable about AIDS, were much more likely to engage in low-risk practices (such as mutual masturbation or body rubbing), and had unprotected anal intercourse less frequently than gay men in smaller cities. The most common sexual activity among gay men in the larger city was mutual masturbation, a low-risk practice. The most common sexual activity among gay men in the smaller cities was unprotected anal intercourse. Increased efforts are needed to educate gay men and to promote risk behavior changes among those living in smaller cities and in communities outside the prominent AIDS epicenters.

    School-based HIV/AIDS education is a common and well-proven intervention strategy for providing information on HIV/AIDS to young people. However, lack of skills among teachers for imparting sensitive information to students can lead to programme failure in terms of achieving goals. A cross-sectional study was conducted among teachers to identify the factors that support or hinder their role in HIV/AIDS education. A self-administered questionnaire was used for interviewing teachers from randomly-selected schools in two adjacent districts in Bangladesh. Based on exposure to teachers' training, the districts were divided into control and intervention areas and the teachers' ability, skill, and their participation in HIV/AIDS education were compared between the districts. Trained teachers in the intervention schools were more likely to participate, less likely to face difficulties, and more likely to use interactive teaching methods in HIV/ AIDS classes compared to the controls who did not receive any training. Inadequate allocation of time for conducting the HIV/AIDS class was found to be barriers to HIV/AIDS education that suggest the need to provide teachers with more support in terms of training and logistics.

    Up to a quarter of the adults who own hearing aids never use them. To provide these 'non-users' with the best help, hearing care professionals need to have an in-depth understanding of the non-users' beliefs and feelings with regard to the non-use. This qualitative study explored these beliefs and feelings in order to increase our understanding of hearing aid non-users. Individual face-to-face semi-structured interviews were completed. Eleven hearing aid owners (aged 54-80 years) who reported that they never or hardly ever used their hearing aids. The participants expressed a variety of feelings towards their non-use, including indifference, self-annoyance, frustration, powerlessness, shame, and guilt. Their feelings were related to beliefs about: (1) the severity of their hearing handicap with and without hearing aids, (2) whom or what was responsible for the non-use, and (3) the attitudes of significant others towards the non-use. Hearing-aid non-users differ in their beliefs and feelings towards the non-use. A patient-centred approach is needed.

    Decentralisation is defined as the dispersion, distribution or transfer of resources, functions and decision-making power from a central authority to regional and local authorities. It is usually accompanied by assignment of accountability and responsibility for results. Fundamental to understanding decentralisation is learning what motivates central governments to give up power and resources to local governments, and the practical significance of this on their positions regarding decentralisation. This study examined key political and institutional influences on role-players' capacity to support decentralisation of HIV and AIDS treatment services to primary healthcare facilities, and implications for sustainability. In-depth interviews were conducted with 55 purposively selected key informants, drawn from three Nigerian states that were at different stages of decentralising HIV and AIDS treatment services to primary care facilities. Key informants represented different categories of role-players involved in HIV and AIDS control programmes. Thematic framework analysis of data was done. Support for decentralisation of HIV and AIDS treatment services to primary healthcare facilities was substantial among different categories of actors. Political factors such as the local and global agenda for health, political tenure and party affiliations, and institutional factors such as consolidation of decision-making power and improvements in career trajectories, influenced role-players support for decentralisation of HIV and AIDS treatment services. It is feasible and acceptable to decentralise HIV and AIDS treatment services to primary healthcare facilities, to help improve coverage. However, role-players' support largely depends on how well the reform aligns with political structures and current institutional practices.

    Synchrotron x-ray topography in grazing-incidence geometry is useful for discerning defects at different depths below the crystal surface, particularly for 4H-SiC epitaxial wafers. However, the penetration depths measured from x-ray topographs are much larger than theoretical values. To interpret this discrepancy, we have simulated the topographic contrast of dislocations based on two of the most basic contrast formation mechanisms, viz. orientation and kinematical contrast. Orientation contrast considers merely displacement fields associated with dislocations, while kinematical contrast considers also diffraction volume, defined as the effective misorientation around dislocations and the rocking curve width for given diffraction vector. Ray-tracing simulation was carried out to visualize dislocation contrast for both models, taking into account photoelectric absorption of the x-ray beam inside the crystal. The results show that orientation contrast plays the key role in determining both the contrast and x-ray penetration depth for different types of dislocation.

    Background Appropriate use of highly active antiretroviral therapy (HAART) can markedly decrease the risk of progression to acquired immunodeficiency syndrome (AIDS) and of premature mortality. We aimed to characterize the trends between 1981 and 2013 in AIDS-defining illnesses (ADIs) and in the number AIDS-related deaths in British Columbia (BC), Canada. Methods We included data of 3550 HIV-positive individuals, aged 19 years or older, from different administrative databases in BC. We estimated the relative risk of developing an ADI over time using a Negative Binomial model, and we investigated trends in the percentage of all deaths associated with AIDS using generalized additive models. Findings The number of ADIs has decreased dramatically to its lowest level in 2013. The peak of the AIDS epidemic in BC happened in 1994 with 696 ADIs being reported (rate 42 ADIs per 100 person-years). Since 1997, the number of ADIs decreased from 253 (rate 7 per 100 person-years) to 84 cases in 2013 (rate 1 per 100 person-years) (p-value equals to zero for the trend in the number of ADIs). We have also shown that out of 22 ADIs considered, only PCP maintained its prominent ranking (albeit with much reduced overall prevalence). Finally, we observed that over time very few deaths were related to AIDS-related causes, especially in the most recent years. Interpretation We showed that the number of new ADIs and AIDS-related mortality have been decreasing rapidly over time in BC. These results provide further evidence that integrated comprehensive free programs that facilitate testing, and deliver treatment and care to this population can be effective in markedly decreasing AIDS-related morbidity and mortality, thus suggesting that controlling and eventually ending AIDS is possible.

    Peter Piot, head of the Joint United Nations Program on HIV/AIDS (UNAIDS), told the World AIDS Conference in Vancouver that India had 3 million people infected with HIV. The Indian government, however, gave no estimate because it has no baseline data upon which a realistic projection can be made. The National AIDS Control Organization (NACO) officially questioned Dr. Piot on the basis of his estimates. Piot attributes his figure to World Health Organization estimates made in consultation with NACO at the end of 1994 that there were 1.75 million people living with HIV in India. Alarmist reports have appeared in the media based upon Dr. Piot's comments. Some health experts, however, believe that the figures are being inflated by the West to pressure India into accepting vaccine trials and other research on HIV-infected people. For now, neither the Indian government nor the country's general population seem concerned about the reported statistics.

  18. Using HIV&AIDS statistics in pre-service Mathematics Education to integrate HIV&AIDS education.

    In South Africa, the HIV&AIDS education policy documents indicate opportunities for integration across disciplines/subjects. There are different interpretations of integration/inclusion and mainstreaming HIV&AIDS education, and numerous levels of integration. Integration ensures that learners experience the disciplines/subjects as being linked and related, and integration is required to support and expand the learners' opportunities to attain skills, acquire knowledge and develop attitudes and values across the curriculum. This study makes use of self-study methodology where I, a teacher educator, aim to improve my practice through including HIV&AIDS statistics in Mathematics Education. This article focuses on how I used HIV&AIDS statistics to facilitate pre-service teacher reflection and introduce them to integration of HIV&AIDS education across the curriculum. After pre-service teachers were provided with HIV statistics, they drew a pie chart which graphically illustrated the situation and reflected on issues relating to HIV&AIDS. Three themes emerged from the analysis of their reflections. The themes relate to the need for further HIV&AIDS education, the changing pastoral role of teachers and the changing context of teaching. This information indicates that the use of statistics is an appropriate means of initiating the integration of HIV&AIDS education into the academic curriculum.

    As one may readily see, the basic avian physical examination should be an extensive, thorough procedure. A wide array of diseases and conditions can be detected during the examination. A flow sheet or checklist should be instituted to maintain consistency and cover all aspects of the history and physical examination. I highly recommend as an adjunct to the basic physical examination Gram stains of the choanae, crop, and cloacae or feces. Owing to the fact that a great number of compromised avian patients either are ill because of gram-negative bacteria or have become more compromised by opportunistic organisms such as yeast or gram-negative bacteria, identification of these conditions greatly facilitates treatment and recovery of the avian patient. Other ancillary tests, such as fecal flotation, complete blood count, culture and sensitivity, Chlamydia test, chemistry profile, radiology, and laparotomy/laparoscopy, are available to the practitioner to aid in the diagnosis of various diseases involving the avian patient. [Editor's note: The editors suggest that the complete blood count be done before an extensive physical examination is undertaken to avoid a stress hemogram.

    Many adolescents with developmental disabilities do not learn the safety skills needed to maintain physical well-being in domestic and community environments. Literacy-based behavioral interventions (LBBIs) that combine print, pictures, and behavioral rehearsal are effective for promoting acquisition and maintenance of self-care skills, but have not been investigated as safety skill intervention. Also, LBBIs have primarily been implemented by teachers and other professionals. In this study, a peer partner was taught to deliver an LBBI story to students so they would learn to perform a basic first aid routine: cleaning and dressing a wound. Results showed that students' accuracy with the first aid routine increased after a peer delivered the LBBI instructional package, and maintained after the peer stopped delivering it. This study demonstrates the effectiveness of the LBBI instructional package for teaching first aid safety skills, and extends previous research showing the efficacy of peers in delivering this intervention.

    More than 20 years ago, even before voters in Oregon had enacted the first aid in dying (AID) statute in the United States, Timothy Quill and colleagues proposed clinical criteria AID. Their proposal was carefully considered and temperate, but there were little data on the practice of AID at the time. (With AID, a physician writes a prescription for life-ending medication for a terminally ill, mentally capacitated adult.) With the passage of time, a substantial body of data on AID has developed from the states of Oregon and Washington. For more than 17 years, physicians in Oregon have been authorized to provide a prescription for AID. Accordingly, we have updated the clinical criteria of Quill, et al., based on the many years of experience with AID. With more jurisdictions authorizing AID, it is critical that physicians can turn to reliable clinical criteria. As with any medical practice, AID must be provided in a safe and effective manner. Physicians need to know (1) how to respond to a patient's inquiry about AID, (2) how to assess patient decision making capacity, and (3) how to address a range of other issues that may arise. To ensure that physicians have the guidance they need, Compassion & Choices convened the Physician Aid-in-Dying Clinical Criteria Committee, in July 2012, to create clinical criteria for physicians who are willing to provide AID to patients who request it. The committee includes experts in medicine, law, bioethics, hospice, nursing, social work, and pharmacy. Using an iterative consensus process, the Committee drafted the criteria over a one-year period.

    2011-09-01

    Despite increasing HIV/AIDS rates among married individuals, minimal research has been conducted on how men and women respond to risk in a marriage. This paper examines strategies used by married individuals to combat HIV/AIDS risk against prevailing gender norms. Qualitative data were gathered in four villages of Cabo Delgado province, Mozambique. Group discussions were held with 160 men and women to explore gender norms, HIV/AIDS knowledge and risk determinants. From the group discussions, 29 individuals were selected for further in-depth interviews to explore relationships between gender norms and risk reduction efforts within marriages. Findings illustrate how infidelity and social limitations placed on condom use not only increase HIV/AIDS risk but also entrench gender disparities. Although power differences between genders can make it difficult to negotiate safe sex, men and women are taking measures to reduce perceived HIV/AIDS risk in their marriage. Married men are reconstructing norms and taking responsibility to protect their family from HIV/AIDS by remaining faithful. For women, responses to HIV/AIDS risk in a marriage are more closely related to their ability to generate an income. Financially dependent women tend to leave a risky marriage altogether in contrast to financially autonomous women who will negotiate condom use with their husband. Factors such as experience with a risky partner, the desire to maintain a good social standing, fear of HIV/AIDS acquisition and parental guidance and support influence men and women to reduce perceived HIV/AIDS risk, despite constraining gender norms and power imbalances in a marriage. Nuanced understandings of the ways in which men and women are already taking measures to decrease noted HIV/AIDS risk, despite gender norms that make this a challenge, should be incorporated into localised responses.

    Nigeria has an estimated 930,000 AIDS orphans, which has a marked impact on family and community. This study was performed to characterise caregivers' knowledge regarding HIV/AIDS and their attitude towards HIV/AIDS, orphans in general and AIDS orphans in particular. Caregivers and non-caregivers aged 25-70 years in Nigeria were interviewed from January and March 2003, and logistic regression analysis was used to determine associations between caregivers' knowledge regarding HIV/AIDS and attitudes towards HIV/AIDS, orphans and AIDS orphans, and demographic characteristics and background status regarding HIV/AIDS and orphans. A total of 824 interviewees participated in the survey (82.4% response rate), of whom 290 (35.2%) were current caregivers of orphans. The mean number of orphans per current caregiver was 1.8 (standard deviation 1.4). Factors related to higher knowledge level regarding HIV/AIDS were female gender [odds ratio (OR) = 3.49; 95% confidence interval (CI): 2.33, 5.22] and belief that AIDS is a common disease (OR = 3.39; 95% CI: 2.19, 5.26). Factors associated with positive attitudes towards HIV/AIDS, orphans in general and AIDS orphans in particular were age 35-44 years (OR = 1.73; 95% CI: 1.11, 2.69), Koranic schooling (OR = 8.69; 95% CI: 2.42, 31.19), polygamy (OR = 1.76; 95% CI: 1.17, 2.62), belief that there are increasing numbers of orphans in the community (OR = 2.59; 95% CI: 1.32, 5.08) and having relatives or friends with HIV/AIDS (OR = 2.88; 95% CI: 1.61, 1.58). There was a slight correlation (r = 0.17, P < 0.001) between caregivers' knowledge regarding HIV/AIDS and positive attitudes towards HIV/AIDS, orphans and AIDS orphans. Demographic characteristics and personal experience should be taken into consideration to improve attitudes and behaviour related to HIV/AIDS and caring for orphans and AIDS orphans.

    Several studies have found reductions in acquired immunodeficiency syndrome (AIDS) risk practices among gay men in high AIDS-prevalence cities since the start of the AIDS crisis. Much less is known about risk behavior patterns among gay men in smaller cities, where AIDS cases are less common and the prevalence of human immunodeficiency virus infection is relatively lower. In the study, men entering gay bars in three cities, one large and two small, completed anonymous surveys of sexual practices and AIDS risk knowledge. Men in high AIDS-prevalence areas were found to have had a greater number of sexual partners, were more knowledgeable about AIDS, were much more likely to engage in low-risk practices (such as mutual masturbation or body rubbing), and had unprotected anal intercourse less frequently than gay men in smaller cities. The most common sexual activity among gay men in the larger city was mutual masturbation, a low-risk practice. The most common sexual activity among gay men in the smaller cities was unprotected anal intercourse. Increased efforts are needed to educate gay men and to promote risk behavior changes among those living in smaller cities and in communities outside the prominent AIDS epicenters. PMID:2502813

    The Chinese government’s response to the increasing number of children orphaned in the HIV epidemic included setting up AIDS orphanages and supporting community-based group homes for double orphans (children who lost both parents to HIV). The impact of these strategies, compared to traditional kinship care, on children’s outcomes has not been studied in China. The purpose of this study was to compare perceived life improvement and life satisfaction among double orphans in 3 main care arrangements (group home, AIDS orphanage, kinship care) in 2 rural Chinese counties. Participants included 176 children from 4 orphanages, 30 from 8 group homes, and 90 from kinship households. Findings indicated that children living in government-supported group homes were more likely to report greater life improvement and positive attitudes toward their current lives than children in orphanages and kinship care. Results suggested that perceived life improvements may have resulted from access to basic needs in extremely poor communities. PMID:19286124

  8. Binocular depth processing in the ventral visual pathway

    Vogels, Rufin

    2016-01-01

    One of the most powerful forms of depth perception capitalizes on the small relative displacements, or binocular disparities, in the images projected onto each eye. The brain employs these disparities to facilitate various computations, including sensori-motor transformations (reaching, grasping), scene segmentation and object recognition. In accordance with these different functions, disparity activates a large number of regions in the brain of both humans and monkeys. Here, we review how disparity processing evolves along different regions of the ventral visual pathway of macaques, emphasizing research based on both correlational and causal techniques. We will discuss the progression in the ventral pathway from a basic absolute disparity representation to a more complex three-dimensional shape code. We will show that, in the course of this evolution, the underlying neuronal activity becomes progressively more bound to the global perceptual experience. We argue that these observations most probably extend beyond disparity processing per se, and pertain to object processing in the ventral pathway in general. We conclude by posing some important unresolved questions whose answers may significantly advance the field, and broaden its scope. This article is part of the themed issue ‘Vision in our three-dimensional world’. PMID:27269602

    The hearing aid effect is the term used to describe the assignment of negative attributes to individuals using hearing aids. The effect was first empirically identified in 1977 when it was reported that adults rating young children with and without hearing aids assigned negative attributes to the children depicted with hearing aids. Investigations in the 1980s and 1990s reported mixed results related to the extent of the hearing aid effect but continued to identify, on average, some negative attributes assigned to individuals wearing hearing aids. The specific aim of this research was to investigate whether the hearing aid effect has diminished in the past several decades by replicating the methods of previous studies for testing the hearing aid effect while using updated devices. Five device configurations were rated across eight attributes. RESULTS for each attribute were considered separately. A total of 24 adults judged pictures of young men wearing various ear level technologies across 8 attributes on a 7-point Likert scale. Five young men between ages 15 and 17 yr were photographed wearing each of five device configurations including (1) a standard-sized behind-the-ear (BTE) hearing aid coupled to an earmold with #13 tubing, (2) a mini-BTE hearing aid with a slim tube open-fit configuration, (3) a completely-in-the-canal hearing aid that could not be seen because of its location in the ear canal, (4) an earbud, and (5) a Bluetooth receiver. The 24 raters saw pictures of each of the 5 young men with each wearing one of the 5 devices so that devices and young men were never judged twice by the same observer. All judgments of each device, regardless of the young man modeling the device, were combined in the data analysis. The effect of device types on judgments was tested using a one-way between-participant analysis of variance. There was a significant difference on the judgment of age and trustworthiness level among the five devices. However, our post hoc

    Fresh water is basic need for life while the source is limited. Therefore, sea water is used as fresh water through desalination process. Sea water has different physical and chemical properties ranging from the surface to the seabed. The energy potential that can be obtained from the hydrostatic pressure also changes according to the depth. As part of the research of the utilization of sea water into fresh water, the aim of this study is to know the characteristics of sea water in the depth that can be utilized as source of fresh water. The sea water samples were taken at 11km from Ujung Kulon beach with depth of 0m, 20m, 40m, 60m, 80m, and 100m under the surface. The results showed that the physical properties at every depth were below the maximum allowable drinking water except for the amount of dissolved solids. Chemical characteristics at any depth above allowable level were fluoride, hardness (CaCo3), chloride, sodium, sulphate, and (KMnO4). In addition to the properties, pressure is one of the considerations in this study to determine the depth of sea water as sources for desalination. Pressure increased by 36.11% as the depth of the sea increased.

    To develop a method of three-dimensional computer aided design (CAD) of post-and-core restoration. Two plaster casts with extracted natural teeth were used in this study. The extracted teeth were prepared and scanned using tomography method to obtain three-dimensional digitalized models. According to the basic rules of post-and-core design, posts, cores and cavity surfaces of the teeth were designed using the tools for processing point clouds, curves and surfaces on the forward engineering software of Tanglong prosthodontic system. Then three-dimensional figures of the final restorations were corrected according to the configurations of anterior teeth, premolars and molars respectively. Computer aided design of 14 post-and-core restorations were finished, and good fitness between the restoration and the three-dimensional digital models were obtained. Appropriate retention forms and enough spaces for the full crown restorations can be obtained through this method. The CAD of three-dimensional figures of the post-and-core restorations can fulfill clinical requirements. Therefore they can be used in computer-aided manufacture (CAM) of post-and-core restorations.

  13. Improving Focal Depth Estimates: Studies of Depth Phase Detection at Regional Distances

    2006-12-01

    The accurate estimation of the depth of small, regionally recorded events continues to be an important and difficult explosion monitoring research problem. Depth phases (free surface reflections) are the primary tool that seismologists use to constrain the depth of a seismic event. When depth phases from an event are detected, an accurate source depth is easily found by using the delay times of the depth phases relative to the P wave and a velocity profile near the source. Cepstral techniques, including cepstral F-statistics, represent a class of methods designed for the depth-phase detection and identification; however, they offer only a moderate level of success at epicentral distances less than 15°. This is due to complexities in the Pn coda, which can lead to numerous false detections in addition to the true phase detection. Therefore, cepstral methods cannot be used independently to reliably identify depth phases. Other evidence, such as apparent velocities, amplitudes and frequency content, must be used to confirm whether the phase is truly a depth phase. In this study we used a variety of array methods to estimate apparent phase velocities and arrival azimuths, including beam-forming, semblance analysis, MUltiple SIgnal Classification (MUSIC) (e.g., Schmidt, 1979), and cross-correlation (e.g., Cansi, 1995; Tibuleac and Herrin, 1997). To facilitate the processing and comparison of results, we developed a MATLAB-based processing tool, which allows application of all of these techniques (i.e., augmented cepstral processing) in a single environment. The main objective of this research was to combine the results of three focal-depth estimation techniques and their associated standard errors into a statistically valid unified depth estimate. The three techniques include: 1. Direct focal depth estimate from the depth-phase arrival times picked via augmented cepstral processing. 2. Hypocenter location from direct and surface-reflected arrivals observed on sparse

    The purpose of this study was to explore and analyze social determinants that influence adherence among Colombian women living with HIV/AIDS in poverty conditions. A qualitative, descriptive-interpretative study was developed. Forty-seven women participated in five focus group discussions. Also, in-depth interviews with six women were conducted. Results showed that women with lower adherence sell their antiretroviral medication to satisfy economic needs, and prioritize the care of their HIV-positive children over their own adherence needs. In contrast, women with higher adherence were found to participate in social support groups offered by nongovernmental organizations. These findings underscore the need to understand the social determinants that facilitate and/or hinder adherence among women in poverty-associated conditions. Results indicate the need to facilitate access to treatment on a timely and continual basis; provide economic resources, including support to meet basic needs as well as subsidies for transportation to health care centers; and explore mechanism for supporting the care of their offspring.

    This study assessed a technology-aided program (monitoring responding, and ensuring preferred stimulation and encouragements) for promoting physical activity with 11 participants with severe/profound intellectual and multiple disabilities. Each participant was provided with an exercise device (e.g. a static bicycle and a stepper) and exposed to the program according to an ABAB design, in which A and B represented baseline and intervention phases, respectively. Data recording concerned (a) the participants' responses with the exercise device (e.g. pedaling) during baseline and intervention phases and (b) their heart rates during the last intervention phase. The results showed that all participants had significant increases in responding with the exercise devices during the intervention phases. Heart-rate values during the intervention sessions indicated that the participants' responding during those sessions mostly amounted to moderate-intensity physical activity, with potential benefits for their overall physical condition. Implications of the findings and questions for future research in the area were discussed.

    This study explored the knowledge and attitudes of Jordanian nurses toward patients with HIV/AIDS, particularly in regards to their sources of information and education. This survey utilized a cross-sectional design. A self-administered questionnaire developed by Eckstein was used in collecting the data. A total of 922 nurses completed the questionnaire. Overall, Jordanian nurses expressed negative attitudes toward patients with HIV/AIDS, and their level of HIV/AIDS knowledge was weak. Weak knowledge level was recorded among nurses in the following subsections: agent and immunology; course and manifestation; transmission and incidence; and precaution and prevention. Only in one subsection (risk group), did nurses show a good level of knowledge about HIV/AIDS. More than two-thirds of nurses (84%) refused to provide care to patients who tested positive for HIV/AIDS. Most of the nurse participants believed that currently provided HIV/AIDS information resources were inadequate (81.4 %). The majority of nurses were interested in support groups for staff nurses (96.5%). The major source of HIV/AIDS information obtained by Jordanian nurses was through Internet web sites (52.7%). The majority of nurses (96.2%) ranked their fear of getting AIDS from their nursing practice as overwhelming. The total attitude of participants towards patients with HIV/AIDS in all five subsections (i.e., fear of contagion, social stigma, fatal outcome of the disease, direct care, and education and counseling) was negative (84.3%). Accurate knowledge about HIV/AIDS along with an in-depth understanding of patients? needs can help alleviate much of the fear, anxiety, and stigma associated with caring for patients with HIV/AIDS.

  18. Communication for HIV/AIDS prevention in Kenya: social-cultural considerations.

    PubMed

    Muturi, Nancy

    2005-01-01

    The acquired immune deficiency syndrome (AIDS) epidemic is spreading fast in Africa in spite of the various efforts and resources put in place to prevent it. In Kenya, reproductive health programs have used the mass media and other communication interventions to inform and educate the public about the disease and to promote behavior change and healthy sexual practices. This effort has led to a discrepancy between awareness and behavioral change among people of reproductive age. In this article I examine the discrepancy in Kenya from a communications perspective addressing social cultural and related factors contributing to the lack of change in behavior and sexual practices. I draw on the theoretical framework of Grunig's model of excellence in communication, the importance of understanding and relationship building between programs and their stakeholders. Data were gathered qualitatively using focus groups and in-depth interviews among men and women in rural Kenya. Key findings indicate that although awareness of sexually transmitted diseases (STDs) including human immunodeficiency virus (HIV)/AIDS is high in Kenya, a majority of the population, particularly those in the rural communities, lack understanding of the communicated messages. They also lack the knowledge of other ways of transmitting HIV particularly among those not sexually involved. Cultural beliefs, values, norms, and myths have played a role in the rapidly increasing epidemic in the rural communities and yet HIV/AIDS communication programs have not addressed these factors adequately. I conclude that successful behavior change communication must include strategies that focus on increasing understanding of the communicated messages and understanding of the audience through application of appropriate methodologies. Building a relationship with the audience or stakeholders through dialogues and two-way symmetrical communication contributes toward this understanding and the maintenance of the newly

    Adequate adherence to HAART has a high impact on survival of AIDA patients. There is little consensus on the causes of low adherence to treatment in women, who are in a situation of inequality in terms of prevention and related care. To explore and describe the socio-cultural aspects related to the adherence of women to antiretroviral treatment for HIV / AIDS. Qualitative, exploratory-descriptive study. The study population was focused on Chilean women, who are 18 years of age or older, living with HIV/AIDS. The sample size was defined by information saturation. In-depth interviews were conducted with 16 women contacted in seven public care centers for people living with HIV (PLHIV) in 4 regions of the country, and it was take into account the saturation of the information. There are several sociocultural factors that determine the level of adherence that women adopt in relation to HAART. The most relevant ones are the vital satisfaction, the imaginary about HIV, the availability of their networks in front of diagnosis and the availability of information are fundamental. It is necessary to enter into specific interventions considering the sociocultural aspects and satisfying the psychosocial needs of women. It is imperative that public policies and health teams consider these aspects to improve adherence to HAART.

  1. Depth and elaboration of processing in relation to age.

    PubMed

    Simon, E

    1979-03-01

    Processing at encoding and retrieval was jointly manipulated, and then the retrieval effectiveness of different cues was directly compared to uncover the relative pattern of deep and elaborate processing in relation to both age and different experimental manipulations. In experiment 1 phonemic and semantic cues were effective retrieval aids for to-be-remembered words in the youngest group; with increasing age, semantic cues decreased in effectiveness more than phonemic cues. These data showed phonemic features to have an importance that is not recognized in the data generated by the typical levels paradigm. When elaboration of the words was induced in Experiment 2 by presenting them in sentences, semantic and context cues were most effective in the youngest group whereas phonemic cues were most effective in the oldest group. Since the pattern of cue effectiveness in the elderly was similar to that in Experiment 1, where the same words were presented alone, it was concluded that aging results in poor elaboration, in particular, in inefficient integration of word events with the context of presentation. These age effects were mimicked in young subjects in Experiment 3 by experimentally restricting encoding time. The present approach uses somewhat modified views of depth and elaboration.

    Hearing loss is a leading cause of disability among older people. Yet only one in seven US adults who could benefit from a hearing aid uses one. This fraction has not increased over the past 30 years, nor have hearing aid prices dropped, despite trends of steady improvements and price reductions in the consumer electronics industry. The President's Council on Science and Technology has proposed changes in the regulation of hearing aids, including the creation of a "basic" low-cost over-the-counter category of devices. We discuss the potential to reduce disability as well as to improve public health, stakeholder responses to the president's council's proposal, and public health efforts to further mitigate the burden of disability stemming from age-related hearing loss.

    Many volcanic hazard factors--such as the likelihood and duration of an eruption, the eruption style, and the probability of its triggering large landslides or caldera collapses--relate to the depth of the magma source. Yet, the magma source depths are commonly poorly known, even in frequently erupting volcanoes such as Hekla in Iceland and Etna in Italy. Here we show how the length-thickness ratios of feeder dykes can be used to estimate the depth to the source magma chamber. Using this method, accurately measured volcanic fissures/feeder-dykes in El Hierro (Canary Islands) indicate a source depth of 11-15 km, which coincides with the main cloud of earthquake foci surrounding the magma chamber associated with the 2011-2012 eruption of El Hierro. The method can be used on widely available GPS and InSAR data to calculate the depths to the source magma chambers of active volcanoes worldwide.

    The issue of basic psychosocial life support during and after disasters is important. People who are affected by disasters can experience severe distress and may need psychosocial support. However, there still are many questions about service design and effectiveness of psychosocial support. During the process of the Targeted Agenda Program, "Prioritizing Care during the Acute Phase: The Prominent Role of Basic Psychosocial Life Support", a team of experts reached consensus on some important issues concerning psychosocial first aid, civil participation, and risk communication. The experts come from many different backgrounds, which supports the notion that psychosocial care deserves special attention within disaster relief programs involving all disciplines and all responsibilities.

    The purpose of this qualitative research study was to gain an understanding of the daily life experiences of eight gay men with HIV/AIDS living alone in New York City. The participants ranged in age from 25 to 50 years. Data were primarily collected using in-depth personal interviews in 1996 followed by telephone interviews 1 year later. Constant-comparison and thematic analyses were used to identify themes and subthemes. Two broad themes with related subthemes were generated from the data. "A Reasonably Stable Base" represented the emotional, physical, and environmental foundation that preexisted or was created as a consequence of living with HIV/AIDS. This theme played a particularly important role in the participants' lives, especially during periods of emotional and physical instability. "Finding and Maintaining Balance" was a second theme that illustrated strategies used for managing and readjusting daily routines, goals, and priorities, as well as how the participants experienced this readjustment process. All of the participants developed their own daily living strategies that were comparable to intervention methods provided in occupational therapy such as energy conservation and work simplification. The findings suggest that occupational therapy practitioners could potentially assist urban gay men with HIV/AIDS with finding and maintaining stability and balance in their daily lives.

    Although studies have shown reductions in mortality from AIDS after the introduction of combination antiretroviral treatment (cART), little is known about cause-specific mortality in low-income settings in the cART era. We explored predictors of AIDS and non-AIDS mortality and compared cause-specific mortality across high-income and low-income settings in the Asia-Pacific region. We followed patients in the Asia Pacific HIV Observational Database from the date they started cART (or cohort enrolment if cART initiation was identified retrospectively), until the date of death or last follow-up visit. Competing risks methods were used to estimate the cumulative incidence, and to investigate predictors, of AIDS and non-AIDS mortality. Of 4252 patients, 215 died; 89 from AIDS, 97 from non-AIDS causes and 29 from unknown causes. Age more than 50 years [hazard ratio 4.29; 95% confidence interval (CI) 2.10-8.79] and CD4 cell counts less than or equal to 100 cells/microl (hazard ratio 8.59; 95% CI 5.66-13.03) were associated with an increased risk of non-AIDS mortality. Risk factors for AIDS mortality included CD4 cell counts less than or equal to 100 cells/microl (hazard ratio 34.97; 95% CI 18.01-67.90) and HIV RNA 10 001 or more (hazard ratio 4.21; 95% CI 2.07-8.55). There was some indication of a lower risk of non-AIDS mortality in Asian high-income, and possibly low-income, countries compared to Australia. Immune deficiency is associated with an increased risk of AIDS and non-AIDS mortality. Older age predicts non-AIDS mortality in the cART era. Less conclusive was the association between country-income level and cause-specific mortality because of the relatively high proportion of unknown causes of death in low-income settings.

    Patient preference is one of the main components of clinical decision making, therefore leading to the development of patient decision aids. The goal of this study was to describe physicians' and patients' viewpoints on the barriers and limitations of using patient decision aids in Iran, their proposed solutions, and, the benefits of using these tools. This qualitative study was conducted in 2011 in Iran by holding in-depth interviews with 14 physicians and 8 arthritis patient. Interviewees were selected through purposeful and maximum variation sampling. As an example, a patient decision aid on the treatment of knee arthritis was developed upon literature reviews and gathering expert opinion, and was presented at the time of interview. Thematic analysis was conducted to analyze the data by using the OpenCode software. The results were summarized into three categories and ten codes. The extracted categories were the perceived benefits of using the tools, as well as the patient-related and physician-related barriers in using decision aids. The following barriers in using patient decision aids were identified in this study: lack of patients and physicians' trainings in shared decision making, lack of specialist per capita, low treatment tariffs and lack of an exact evaluation system for patient participation in decision making. No doubt these barriers demand the health authorities' special attention. Hence, despite patients and physicians' inclination toward using patient decision aids, these problems have hindered the practical usage of these tools in Iran--as a developing country.

    Small-scale geochemical gradients are a key feature of aquifer contaminant plumes, highlighting the need for functional and structural profiling of corresponding microbial communities on a similar scale. The purpose of this study was to characterize the microbial functional and structural diversity with depth across representative redox zones of a hydrocarbon plume and an adjacent wetland, at the Bemidji Oil Spill site. A combination of quantitative PCR, denaturing gradient gel electrophoresis, and pyrosequencing were applied to vertically sampled sediment cores. Levels of the methanogenic marker gene, methyl coenzyme-M reductase A (mcrA), increased with depth near the oil body center, but were variable with depth further downgradient. Benzoate degradation N (bzdN) hydrocarbon-degradation gene, common to facultatively anaerobic Azoarcus spp., was found at all locations, but was highest near the oil body center. Microbial community structural differences were observed across sediment cores, and bacterial classes containing known hydrocarbon degraders were found to be low in relative abundance. Depth-resolved functional and structural profiling revealed the strongest gradients in the iron-reducing zone, displaying the greatest variability with depth. This study provides important insight into biogeochemical characteristics in different regions of contaminant plumes, which will aid in improving models of contaminant fate and natural attenuation rates.

  10. Aid and good governance: Examining aggregate unintended effects of aid.

    PubMed

    Dijkstra, Geske

    2018-06-01

    Although donors generally aim to improve governance in recipient countries by various means, critics claim that the aggregate effect of large aid flows is the deterioration of governance. Aid is said to weaken domestic accountability, sustain authoritarian regimes, increase political instability, weaken government capacities, and increase corruption. Conducting a systematic search in Web of Science, this paper reviews the empirical evidence for these unintended aggregate effects of aid on the political, administrative, and judicial dimensions of good governance. It finds that the negative effects of aid on governance are much exaggerated. The aggregate effect of aid on democracy has become more positive after the Cold War, and the effect of aid on government capacity and on reducing corruption has also improved over time. Furthermore, most studies show a positive effect of aid on political stability. These findings imply that donor intentions matter: donors that are serious about their intended effects on governance are able to mitigate the possible negative unintended effects of their aid.

    2017-08-01

    Future infrared remote sensing systems, such as monitoring of the Earth's environment by satellites, infrastructure inspection by unmanned airborne vehicles etc., will require 16 bit depth infrared images to be compressed and stored or transmitted for further analysis. Such systems are equipped with low power embedded platforms where image or video data is compressed by a hardware block called the video processing unit (VPU). However, in many cases using two 8-bit VPUs can provide advantages compared with using higher bit depth image compression directly. We propose to compress 16 bit depth images via 8 bit depth codecs in the following way. First, an input 16 bit depth image is mapped into 8 bit depth images, e.g., the first image contains only the most significant bytes (MSB image) and the second one contains only the least significant bytes (LSB image). Then each image is compressed by an image or video codec with 8 bits per pixel input format. We analyze how the compression parameters for both MSB and LSB images should be chosen to provide the maximum objective quality for a given compression ratio. Finally, we apply the proposed infrared image compression method utilizing JPEG and H.264/AVC codecs, which are usually available in efficient implementations, and compare their rate-distortion performance with JPEG2000, JPEG-XT and H.265/HEVC codecs supporting direct compression of infrared images in 16 bit depth format. A preliminary result shows that two 8 bit H.264/AVC codecs can achieve similar result as 16 bit HEVC codec.

    Responses of species to disturbances give insights into how species might respond to future wetland changes. In this study, species of monsoonal wetlands belonging to various functional types (graminoid and non−graminoid emergents, submersed aquatic, floating−leaved aquatic) varied in their growth responses to water depth and harvesting. We tested the effects of water depth (moist soil, flooded) and clipping (unclipped, and clipped) on the biomass and longevity of twenty−three dominant plant species of monsoonal wetlands in the Keoladeo National Park, India in a controlled experiment. With respect to total biomass and survival, six species responded positively to flooding and twelve species responded negatively to clipping. Responses to flooding and clipping, however, sometimes interacted. Individualistic responses of species to water levels and clipping regimes were apparent; species within a functional group did not always respond similarly. Therefore, detailed information on the individualistic responses of species may be needed to predict the vegetation composition of post−disturbance wetlands. In particular, as demands for fresh water increase around the world, studies of life history constraints and responses to hydrological changes will aid wetland managers in developing strategies to conserve biodiversity.

    Estimates of flood depths are needed for design of roadways across flood plains and for other types of construction along streams. Equations for estimating flood depths in Tennessee were derived using data for 150 gaging stations. The equations are based on drainage basin size and can be used to estimate depths of the 10-year and 100-year floods for four hydrologic areas. A method also was developed for estimating depth of floods having recurrence intervals between 10 and 100 years. Standard errors range from 22 to 30 percent for the 10-year depth equations and from 23 to 30 percent for the 100-year depth equations. (USGS)

    A deterministic compartmental sex-structured HIV/AIDS model for assessing the effects of homosexuals and bisexuals in heterosexual settings in which homosexuality and bisexuality issues have remained taboo is presented. We extend the model to focus on the effects of condom use as a single strategy approach in HIV prevention in the absence of any other intervention strategies. Initially, we model the use of male condoms, followed by incorporating the use of both the female and male condoms. The model includes two primary factors in condom use to control HIV which are condom efficacy and compliance. Reproductive numbers for these models are computed and compared to assess the effectiveness of male and female condom use in a community. We also extend the basic model to consider the effects of antiretroviral therapy as a single strategy. The results from the study show that condoms can reduce the number of secondary infectives and thus can slow the development of the HIV/AIDS epidemic. Further, we note from the study that treatment of AIDS patients may enlarge the epidemic when the treatment drugs are not 100% effective and when treated AIDS patients indulge in risky sexual behaviour. Thus, the treatment with amelioration of AIDS patients should be accompanied with intense public health educational programs, which are capable of changing the attitude of treated AIDS patients towards safe sex. It is also shown from the study that the use of condoms in settings with the treatment may help in reducing the number of secondary infections thus slowing the epidemic.

    Many volcanic hazard factors - such as the likelihood and duration of an eruption, the eruption style, and the probability of its triggering large landslides or caldera collapses - relate to the depth of the magma source. Yet, the magma source depths are commonly poorly known, even in frequently erupting volcanoes such as Hekla in Iceland and Etna in Italy. Here we show how the length-thickness ratios of feeder dykes can be used to estimate the depth to the source magma chamber. Using this method, accurately measured volcanic fissures/feeder-dykes in El Hierro (Canary Islands) indicate a source depth of 11–15 km, which coincides with the main cloud of earthquake foci surrounding the magma chamber associated with the 2011–2012 eruption of El Hierro. The method can be used on widely available GPS and InSAR data to calculate the depths to the source magma chambers of active volcanoes worldwide. PMID:24067336

    Progress in hearing aids has come a long way. Yet despite such progress hearing aids are not the perfect answer to many hearing problems. Some adult ears cannot accommodate tightly fitting hearing aids. Mouth movements such as chewing, talking, and athletic or other active endeavors also lead to loosely fitting ear molds. It is well accepted that loosely fitting hearing aids are the cause of feedback noise. Since feedback noise is the most common complaint of hearing aid wearers it has been the subject of various patents. Herein a hearing aid assembly is provided eliminating feedback noise. The assembly includes the combination of a hearing aid with a headset developed to constrict feedback noise.

  20. AIDS in South Africa. Puppet power.

    PubMed

    Friedman, G

    1992-01-01

    Blacks in South Africa see the government campaign promoting condom use to prevent AIDS as a political ruse to control population growth among Blacks. The City Health Department of Johannesburg does not use a government created poster targeted to Blacks because it implies that only Blacks have AIDS. Even though the number of AIDS cases in South Africa is lower (700 reported cases) than that of its neighbors, the number of HIV infected individuals is growing. So nongovernmental organizations are trying to overcome the division between the government and Blacks by finding alternative ways to stem the AIDS epidemic. The African Research and Educational Puppetry Programme uses Puppets Against AIDS to bridge racial, cultural, language, and educational barriers to thus educate Blacks about AIDS. It not only hopes to create and perform educational and socially valuable theater, but also to rediscover performing arts traditions in southern and central Africa. Since about 76% of the black population in rural South Africa is illiterate, the gray skinned puppets constitute an interactive and inoffensive way to communicate a serious message. Someone demonstrates how to put on a condom using a life size model which induces controversy among physicians and educated whites. Blacks in Johannesburg and surrounding townships are not offended, however. In fact, many have never seen condoms before the demonstration. The puppets emphasize that safe sex and having sex with only 1 partner can stop the spread of AIDS. Each performance also includes live African percussion and music. A narrator distributes free condoms and AIDS information brochures to the audience. Videotapes of each performance are used to evaluate audience reactions. Independent evaluation teams evaluate the impact of the performance. 1-4 day workshops on AIDS, puppet making, story development, and performing skills follow each performance.

    NREL researchers are supporting offshore wind power development with computer models that allow detailed analyses of both fixed and floating offshore wind turbines. While existing computer-aided engineering (CAE) models can simulate the conditions and stresses that a land-based wind turbine experiences over its lifetime, offshore turbines require the additional considerations of variations in water depth, soil type, and wind and wave severity, which also necessitate the use of a variety of support-structure types. NREL's core wind CAE tool, FAST, models the additional effects of incident waves, sea currents, and the foundation dynamics of the support structures.

    Despite anecdotal evidence that the quality of governance in recipient countries affects the allocation of international health aid, there is no quantitative evidence on the magnitude of this effect, or on which dimensions of governance influence donor decisions. We measure health-aid flows over 1995-2006 for 109 aid recipients, matching aid data with measures of different dimensions of governance and a range of country-specific economic and health characteristics. Everything else being equal, countries with more political rights receive significantly more aid, but so do countries with higher corruption levels. The dependence of aid on political rights, even when we control for other governance indicators, suggests that health aid is sometimes used as an incentive to reward political reforms.

    People living with AIDS are at increased risk of developing certain cancers. Since the introduction of the highly active antiretroviral therapy (HAART), the incidence of AIDS-defining cancers (ADCs) has decreased in high-income countries. The objective of this study was to analyse trends in ADCs and non-AIDS-defining cancers (NADCs) in HIV-positive people with a diagnosis of AIDS, in comparison to the general population, in São Paulo, Brazil. A probabilistic record linkage between the 'Population-based Cancer Registry of São Paulo' and the AIDS notification database (SINAN) was conducted. Cancer trends were assessed by annual per cent change (APC). In people with AIDS, 2074 cancers were diagnosed. Among men with AIDS, the most frequent cancer was Kaposi's sarcoma (469; 31.1%), followed by non-Hodgkin lymphoma (NHL; 304; 20.1%). A decline was seen for ADCs (APC = -14.1%). All NADCs have increased (APC = 7.4%/year) significantly since the mid-2000s driven by the significant upward trends of anal (APC = 24.6%/year) and lung cancers (APC = 15.9%/year). In contrast, in men from the general population, decreasing trends were observed for these cancers. For women with AIDS, the most frequent cancer was cervical (114; 20.2%), followed by NHL (96; 17.0%). Significant declining trends were seen for both ADCs (APC = -15.6%/year) and all NADCs (APC = -15.8%/year), a comparable pattern to that found for the general female population. Trends in cancers among people with AIDS in São Paulo showed similar patterns to those found in developed countries. Although ADCs have significantly decreased, probably due to the introduction of HAART, NADCs in men have shown an opposite upward trend.

    Full thickness blocks of canine humeral cartilage were microtomed into both perpendicular sections and a series of 100 parallel sections, each 6 μm thick. Fourier Transform Infrared Imaging (FTIRI) was used to image each tissue section eleven times under different infrared polarizations (from 0° to 180° polarization states in 20° increments and with an additional 90° polarization), at a spatial resolution of 6.25 μm and a wavenumber step of 8 cm−1. With increasing depth from the articular surface, amide anisotropies increased in the perpendicular sections and decreased in the parallel sections. Both types of tissue sectioning identified a 90° difference between amide I and amide II in the superficial zone of cartilage. The fibrillar distribution in the parallel sections from the superficial zone was shown to not be random. Sugar had the greatest anisotropy in the upper part of the radial zone in the perpendicular sections. The depth-dependent anisotropic data were fitted with a theoretical equation that contained three signature parameters, which illustrate the arcade structure of collagens with the aid of a fibril model. Infrared imaging of both perpendicular and parallel sections provides the possibility of determining the three-dimensional macromolecular structures in articular cartilage. Being sensitive to the orientation of the macromolecular structure in healthy articular cartilage aids the prospect of detecting the early onset of the tissue degradation that may lead to pathological conditions such as osteoarthritis.

    Antibody discovery has become increasingly important in almost all areas of modern medicine. Different antibody discovery approaches exist, but one that has gained increasing interest in the field of toxinology and antivenom research is phage display technology. In this review, the lifecycle of the M13 phage and the basics of phage display technology are presented together with important factors influencing the success rates of phage display experiments. Moreover, the pros and cons of different antigen display methods and the use of naïve versus immunized phage display antibody libraries is discussed, and selected examples from the field of antivenom research are highlighted. This review thus provides in-depth knowledge on the principles and use of phage display technology with a special focus on discovery of antibodies that target animal toxins.

    The Sun article, "Employers finding that AIDS in the workplace is a managerial nightmare" (April 3), did not accurately portray the status of AIDS in the workplace. The AIDS virus, HTLV III, is transmitted by body fluids, primarily semen and blood, and there is no known risk of transmitting the virus by casual contact in the workplace. The Center for Disease Control (CDC) released guidelines for child care workers last August. Guidelines on preventing transmission of AIDS in the workplace were issued by CDC in November 1985. These guidelines specifically discussed health care, personal service, and food service workers. The recommendations were against routine screening. Furthermore, employment should not be restricted on the basis of a positive HTLV III antibody test. A person with HTLV III infection should be exempt from the workplace only if there are circumstances interfering with job performance. In Maryland, the Governor's Task Force on AIDS has gone on record as endorsing CDC guidelines related to employment. Furthermore, the task force condemns discrimination based on the disease AIDS, AIDS Related Complex (ARC), or HTLV III infection. Increasingly AIDS patients are being considered legally disabled and therefore are protected by federal and state laws prohibiting discrimination on the basis of a handicap. Marylanders who are subjected to mandatory HTLV III screening in the workplace, or if discriminated against on the basis of HTLV III inefction, should contact the Maryland Commission on Human Relations, the Maryland Department of Health and Mental Hygiene, or the Health Education Resource Organization (HERO). All 3 of these resources guarantee confidentiality. It is only by employees reporting incidents that a nightmare in the workplace can be avoided in Maryland. full text

  8. Evaluating methods for controlling depth perception in stereoscopic cinematography

    2009-02-01

    Existing stereoscopic imaging algorithms can create static stereoscopic images with perceived depth control function to ensure a compelling 3D viewing experience without visual discomfort. However, current algorithms do not normally support standard Cinematic Storytelling techniques. These techniques, such as object movement, camera motion, and zooming, can result in dynamic scene depth change within and between a series of frames (shots) in stereoscopic cinematography. In this study, we empirically evaluate the following three types of stereoscopic imaging approaches that aim to address this problem. (1) Real-Eye Configuration: set camera separation equal to the nominal human eye interpupillary distance. The perceived depth on the display is identical to the scene depth without any distortion. (2) Mapping Algorithm: map the scene depth to a predefined range on the display to avoid excessive perceived depth. A new method that dynamically adjusts the depth mapping from scene space to display space is presented in addition to an existing fixed depth mapping method. (3) Depth of Field Simulation: apply Depth of Field (DOF) blur effect to stereoscopic images. Only objects that are inside the DOF are viewed in full sharpness. Objects that are far away from the focus plane are blurred. We performed a human-based trial using the ITU-R BT.500-11 Recommendation to compare the depth quality of stereoscopic video sequences generated by the above-mentioned imaging methods. Our results indicate that viewers' practical 3D viewing volumes are different for individual stereoscopic displays and viewers can cope with much larger perceived depth range in viewing stereoscopic cinematography in comparison to static stereoscopic images. Our new dynamic depth mapping method does have an advantage over the fixed depth mapping method in controlling stereo depth perception. The DOF blur effect does not provide the expected improvement for perceived depth quality control in 3D cinematography

    The purpose of the study was to assess whether Internet competency predicted practical hearing aid knowledge and handling skills in first-time hearing aid users. The design was a prospective, randomized controlled trial of a multimedia educational intervention consisting of interactive video tutorials (or reusable learning objects [RLOs]). RLOs were delivered through DVD for TV or PC, and online. Internet competency was measured at the hearing aid fitting appointment, whereas hearing aid knowledge and practical handling skills were assessed 6 weeks postfitting. Internet competency predicted practical hearing aid knowledge and handling skills, controlling for age, hearing sensitivity, educational status, and gender for the group that received the RLOs. Internet competency was inversely related to the number of times the RLOs were watched. Associations between Internet competency and practical hearing aid knowledge, handling skills, and watching the RLOs fewer times may have arisen because of improved self-efficacy. Therefore, first-time hearing aid users who are more competent Internet users may be better equipped to apply newly learned information to effectively manage their hearing loss.

  10. AIDS in Thailand.

    1991-02-18

    The reasons for the rapid spread of AIDS in Thailand, and the impact of the unique non-governmental agency Population and Community Development Association (PDA) directed by the charismatic Dr. Mechai are described. The rapid spread of AIDS in Thailand is due to presence of all possible factors facilitating HIV transmission, a large population of injecting drug addicts, an extensive mobile domestic and tourist sex industry, and an active gay community. The number of HIV-positive persons rose from 179 in 1988 to 16,359 in 1989, and is now estimated at 100,000. 1% of the Thai population works in prostitution, and from 16% of the high-income to 72% of the low-income prostitutes are infected, with their infection rates rising 10% per month. 75% of Thai men use cheap prostitutes. While the government was ignoring the AIDS threat in the early '80s, Dr. Mechai, whose name translated as "condom," was organizing the grass-roots community-based condom distribution system PDA, said to be responsible for the fall in annual population growth from 3.4% in 1968 to 1.5% in 1990. His organization now distributes contraceptives to 16,000 villages by 12,000 volunteers. He uses booklets, cards, cassettes, slide shows, videos and appearances with condom-inflating contests and costumes to de-mystify condoms with humor. Now AIDS messages are heard in taxis, on military TV and radio, and in remote villages. Converting knowledge into practice is more difficult, requiring tactful convincing of brothel operators and finding some way to reach their clients, who exert economic control over young female prostitutes.

  11. Alternate approach for calculating hardness based on residual indentation depth: Comparison with experiments

    It is well known that plastic deformation is a highly nonlinear dissipative irreversible phenomenon of considerable complexity. As a consequence, little progress has been made in modeling some well-known size-dependent properties of plastic deformation, for instance, calculating hardness as a function of indentation depth independently. Here, we devise a method of calculating hardness by calculating the residual indentation depth and then calculate the hardness as the ratio of the load to the residual imprint area. Recognizing the fact that dislocations are the basic defects controlling the plastic component of the indentation depth, we set up a system of coupled nonlinear time evolution equations for the mobile, forest, and geometrically necessary dislocation densities. Within our approach, we consider the geometrically necessary dislocations to be immobile since they contribute to additional hardness. The model includes dislocation multiplication, storage, and recovery mechanisms. The growth of the geometrically necessary dislocation density is controlled by the number of loops that can be activated under the contact area and the mean strain gradient. The equations are then coupled to the load rate equation. Our approach has the ability to adopt experimental parameters such as the indentation rates, the geometrical parameters defining the Berkovich indenter, including the nominal tip radius. The residual indentation depth is obtained by integrating the Orowan expression for the plastic strain rate, which is then used to calculate the hardness. Consistent with the experimental observations, the increasing hardness with decreasing indentation depth in our model arises from limited dislocation sources at small indentation depths and therefore avoids divergence in the limit of small depths reported in the Nix-Gao model. We demonstrate that for a range of parameter values that physically represent different materials, the model predicts the three characteristic

    2016-10-01

    Minimally invasive surgery (MIS) poses visual challenges to the surgeons. In MIS, binocular disparity is not freely available for surgeons, who are required to mentally rebuild the 3-dimensional (3D) patient anatomy from a limited number of monoscopic visual cues. The insufficient depth cues from the MIS environment could cause surgeons to misjudge spatial depth, which could lead to performance errors thus jeopardizing patient safety. In this article, we will first discuss the natural human depth perception by exploring the main depth cues available for surgeons in open procedures. Subsequently, we will reveal what depth cues are lost in MIS and how surgeons compensate for the incomplete depth presentation. Next, we will further expand our knowledge by exploring some of the available solutions for improving depth presentation to surgeons. Here we will review the innovative approaches (multiple 2D camera assembly, shadow introduction) and devices (3D monitors, head-mounted devices, and auto-stereoscopic monitors) for 3D image presentation from the past few years. © The Author(s) 2016.

  15. AIDS in contemporary Islamic ethical literature.

    PubMed

    Francesca, Ersilia

    2002-01-01

    AIDS has been mentioned in Islamic ethical literature since about 1985 as an illness pertaining to European and American homosexuals. Only since about 1990 has the presence of HIV/AIDS in Islamic countries cast light on the fact that the actual sexual behaviour of the population does not always conform to religious norms. The increase in the numbers of people with HIV has compelled religious leaders to take a stand on sexual practices they consider "deviant", from prostitution to homosexuality and extramarital sex. The aim of this paper is to analyse the attitude of Muslim religious authorities towards individual sexual behaviour and AIDS. It is based mainly on contemporary legal responses that largely provide the necessary information on most of Islamic medical ethics. According to Muslim scholars, AIDS is a warning from God not to indulge in illicit conduct. As a remedy against the spread of AIDS, they encourage compliance with traditional family values and the enhancement of faith and devotion and strongly oppose sex education. They oppose promotion of condoms or any form of safe sex outside of marriage, which they perceive as promoting promiscuity and defiance of divine law. All the above-mentioned arguments are not exhaustive of the Islamic attitude towards AIDS. Some religious groups disagree with such a conservative way of conceiving the fight against AIDS as being antithetical to both men's and women's well-being. They support an alternative view of reproductive health and human rights within the Islamic framework and stress the great tolerance of Islam and why it must include people with HIV and AIDS.

    Bottom of sulcus dysplasias (BOSDs) are localized focal cortical dysplasias (FCDs) centred on the bottom of a sulcus that can be highly epileptogenic, but difficult to delineate intraoperatively. We report on a patient with refractory epilepsy due to a BOSD, successfully resected with the aid of a multimodal surgical approach using neuronavigation based on MRI and PET, intraoperative ultrasound (iUS) and electrocorticography (ECoG) using depth electrodes. The lesion could be visualized on iUS showing an increase in echogenicity at the grey-white matter junction. IUS demonstrated the position of the depth electrode in relation to the lesion. Depth electrode recording showed almost continuous spiking. Thus, intraoperative imaging and electrophysiology helped confirm the exact location of the lesion. Post-resection ultrasound demonstrated the extent of the resection and depth electrode recording did not show any epileptiform activity. Thus, both techniques helped assess completeness of resection. The patient has been seizure free since surgery. Using a multimodal approach including iUS and ECoG is a helpful adjunct in surgery for BOSD and may improve seizure outcome.

  19. Changes in Root Decomposition Rates Across Soil Depths

    2016-12-01

    Over half of global soil organic carbon (SOC) is stored in subsurface soils (>30 cm). Turnover times of soil organic carbon (SOC) increases with depth as evidenced by radiocarbon ages of 1,000 to more than 10,000 years in many deep soil horizons but the reasons for this increase are unclear. Many factors that potentially control SOC decomposition change with depth such as increased protection of SOC in aggregates or organo-mineral complexes and increased spatial heterogeneity of SOC "hotspots" like roots, which limit the accessibility of SOC to microbes. Lower concentrations of organic matter at depth may inhibit microbial activity due to energy limitation, and the microbial community itself changes with depth. To investigate how SOC decomposition differs with depth, we inserted a 13C-labeled fine root substrate into three depths (15, 50, and 90 cm) in a coniferous forest Alfisol and measured the root carbon remaining in particulate (>2 mm), bulk (< 2mm), free light, and mineral soil fractions over 2.5 years. We also characterized how the microbial community and SOC changed with depth. Initial rates of decomposition were unaffected by soil depth—50% of root carbon was lost from all depths within the first year. However, after 2.5 years, decomposition rates were affected by soil depth with only 15% of the root carbon remaining at 15 cm while 35% remained at 90 cm. Microbial communities, based on phospholipid fatty acid analysis, changed with depth—fungal biomarkers decreased whereas actinomycetes biomarkers increased. However, the preferences of different microbial groups for the 13C-labeled root carbon were consistent with depth. In contrast, the amount of mineral-associated SOC did not change with depth. Thus, decreased decomposition rates in this deep soil are not due to mineral associations limiting SOC availability, but may instead be due to changes in microbial communities, particularly in the microbes needed to carry out the later stages of root

    Incorrect endobronchial placement of the tracheal tube can lead to serious complications. Hence, it is necessary to determine the accuracy of tracheal tube positioning. Markers are included on tracheal tubes, in the process of their manufacture, as indicators of approximate intubation depth. In addition, continuous chest auscultation has been used for determining the proper position of the tube. We examined insertion depth using the cuff depth and continuous chest auscultation method (CC method), compared with insertion depth determined by the marker method, to assess the accuracy of these methods. After induction of anesthesia, tracheal intubation was performed in each patient. In the CC method, the depth of tube insertion was measured when the cuff had passed through the glottis, and again when breath sounds changed in quality; the depth of tube insertion was determined from these values. In the marker method, the depth of tube insertion was measured and determined when the marker of the tube had reached the glottis, using insertion depth according to the marker as an index. Insertion depth by the marker method was 26.6 ± 1.2 cm and by the CC method was 28.0 ± 1.2 cm (P < 0.0001). The CC method indicated a significantly greater depth than the marker method. This study determined the safe range of tracheal tube placement. Tube positions determined by the CC method were about 1 cm deeper than those determined by the marker. This information is important to prevent accidental one-lung ventilation and accidental extubation. UMIN No. UMIN000011375.

    2013-01-01

    As early as the 1930s the term Master Hearing Aid (MHA) described a device used in the fitting of hearing aids. In their original form, the MHA was a desktop system that allowed for simulated or actual adjustment of hearing aid components that resulted in a changed hearing aid response. Over the years the MHA saw many embodiments and contributed to a number of rationales for the fitting of hearing aids. During these same years, the MHA was viewed by many as an inappropriate means of demonstrating hearing aids; the audio quality of the desktop systems was often superior to the hearing aids themselves. These opinions and the evolution of the MHA have molded the modern perception of hearing aids and the techniques used in the fitting of hearing aids. This article reports on a history of the MHA and its influence on the fitting of hearing aids. PMID:23686682

Total number of the same type of administrative visits recorded by the previous system (TASS) during the period from February to July 2003. The mean number of administrative visits per month during the period from February to July 2003 was 160, compared to a mean number of 64 visits during the period from February to July 2004. The reduction in the number of visits for prescription renewal was 60%. Introducing a system for computer-aided prescribing significantly reduced the number of administrative visits for prescription renewal for long-term treatment. This could help reduce the administrative burden considerably in primary care if the system were used in all centers.

    Feedback control of the penetration force applied to a pin tool in friction stir welding has been found to be a robust and reliable means for controlling the depth of penetration of the tool. This discovery has made it possible to simplify depth control and to weld with greater repeatability, even on workpieces with long weld joints. Prior to this discovery, depths of penetration in friction stir welding were controlled by hard-tooled roller assemblies or by depth actuators controlled by feedback from such external sensors as linear variable-differential transformers or laser-based devices. These means of control are limited: A hard-tooled roller assembly confines a pin tool to a preset depth that cannot be changed easily during the welding process. A measurement by an external sensor is only an indirect indicative of the depth of penetration, and computations to correlate such a measurement with a depth of penetration are vulnerable to error. The present force-feedback approach exploits the proportionality between the depth and the force of penetration Unlike a depth measurement taken by an external sensor, a force measurement can be direct because it can be taken by a sensor coupled directly to the pin tool. The reading can be processed through a modern electronic servo control system to control an actuator to keep the applied penetration force at the desired level. In comparison with the older depth-control methods described above, this method offers greater sensitivity to plasticizing of the workpiece metal and is less sensitive to process noise, resulting in a more consistent process. In an experiment, a tapered panel was friction stir welded while controlling the force of penetration according to this method. The figure is a plot of measurements taken during the experiment, showing that force was controlled with a variation of 200 lb (890 N), resulting in control of the depth of penetration with a variation of 0.004 in. (0.1 mm).

    Develop an effective First Aid's system in workplaces is significantly important to the outcomes of accidents at work, thus contributing positively to create healthy and safe environments, improving responsible attitude and risk perception by workers. The italian regulation (D. Lgs. 81/08; DM 388/03) gives an important role to First Aid within the system for managing health and safety in workplaces and requires the employers to designate and train workers and organize facilities in the workplace. However, to ensure that First Aid's system actually contributes to increasing health and safety in workplaces, it's necessary to verify its effectiveness, beyond the law compliance. The article stands to evaluate the critical issues and related innovations to be introduced in this context, by analyzing data from literature and field experiences involving actors in the prevention system. The goal is to provide suggestions and action proposals to improve first aid's system in workplaces, paying particular attention to the aiders training (selection, motivation, teaching methods, retraining), as well as introduce to innovations to allow an immediate and timely emergency response (company equipments, other useful devices). On this last aspect, it has given particular emphasis to the introduction of semi-automatic defibrillator (AED), which is essential in case of sudden cardiac arrest with ventricular fibrillation, and special aiders training by means of BLSD (Basic Life Support and Defibrillation) courses based on international guidelines.

    To describe the resources for medical condition management in mountain huts and the epidemiology of such events. We conducted a 3-step study from April 2013 to August 2014 in French mountain huts. The first step consisted of collecting data regarding the first aid equipment available in mountain huts. The second step consisted of a qualitative evaluation of the mountain hut guardian's role in medical situations through semistructured interviews. Finally, a prospective observational study was conducted in the summer season to collect all medical events (MEs) that occurred during that period. Out of 164 hut guardians, 141 (86%) had a basic life support diploma. An automatic external defibrillator was available in 41 (26%) huts, and 148 huts (98%) were equipped with a first aid kit. According to semistructured interviews, hut guardians played a valuable role in first aid assistance. Regarding the observational study, 306 people requested the hut guardian's help for medical reasons in 87 of the 126 huts included. A total of 501 MEs for approximately 56,000 hikers (0.85%) were reported, with 280 MEs (56%) involving medical pathologies and 221 (44%) MEs involving trauma-related injuries. MEs had low prevalence, but the hut guardian played a valuable role as a first aid responder. Copyright © 2016 Wilderness Medical Society. Published by Elsevier Inc. All rights reserved.

    To explored the role of family-centered care in supporting children living with HIV and AIDS in Nigeria. A qualitative research design was adopted for this study with a grounded theory approach. Children aged between 11 and 14 years living with HIV and AIDS, their caregivers, and nurse practitioners working in the HIV clinic were engaged in separate focus group discussions in two hospitals in Nigeria. The findings showed that the value African families place on children plays a significant role in identifying their care needs and providing their basic necessities; hence, people around the sick child tend to make him feel better, as attested by nurse practitioners and caregiver participants. Nurse practitioner participants cited unified families as providing care support and love to the children and the support needed to alleviate their sicknesses. Children participants confirmed that family members/relatives were always at their disposal to provide supportive care in terms of administrating antiretroviral medication as well as other psychological care; although a few participants indicated that disruption in family structures in resource-poor settings, isolation and withdrawal, and deprivation of care due to poverty threatened the care rendered to the children. The study highlighted the value attached to children in the African context as helping family members to identify the care needs of children living with HIV and AIDS; thereby providing succor to alleviate their sicknesses and enhance their quality of life. © 2016 Japan Academy of Nursing Science.

    Motivation has a major impact on the results of a child's learning at school and a student's learning at the University. Moreover, school education creates a foundation for the study at the university, which is used by a student for in-depth and rapid development of specialized disciplines, reaching the level of independent research and development. The modern system of teaching physics at school is built in such a way that, basically, a teacher is demonstrating and a child is looking. Such a system, in addition to the logical lack of practical skills, leads to a significant reduction in the motivation for further engineering study, which is now a priority for Russia. There are original methods of practical teaching for students starting from the 5th grade, which allow each student to try to assemble on their own a variety of devices, reaching quick practical results. The principles of this technique are discussed in the article. Prototyping boards without solder were chosen as the basic platform to showcase the methodology.

    AIDS will be remembered as the illness that was discovered in the 1980s of which the effects of this epidemic were only realised in the 1990s. Statistics show that the number of patients with AIDS increase annually because of the number of patients now diagnosed as HIV infected. Statistics indicate that AIDS has a much wider impact on the community than only homosexuals and drug-dependent people. Much attention is paid currently to the prevention of AIDS, but the problem is vested in the third phase of the HIV infection, namely AIDS. Nurses will be more and more exposed to the patient with AIDS and she can make a valuable contribution to facilitating the quest to wholeness of the patient with AIDS. This research was aimed at exploring and describing the experiences of the patient with AIDS and to lay down guidelines for the nurse and the psychiatric nurse specialist as consultant to facilitate the quest for wholeness of the patient with AIDS. A exploratory, descriptive contextual study was done with the aim of achieving insight into the experiences of the patient with AIDS, by way of a specific convenience test sample, five patients who complied with the set criteria were included in the research. The application possibilities of this research are generally set out as regards practice, research and teaching, and also as specific guidelines for the nurse treating the patient with AIDS. By following the guidelines set out in this research, the nurse can facilitate the patient's quest for wholeness.

    2016-06-19

    One of the most powerful forms of depth perception capitalizes on the small relative displacements, or binocular disparities, in the images projected onto each eye. The brain employs these disparities to facilitate various computations, including sensori-motor transformations (reaching, grasping), scene segmentation and object recognition. In accordance with these different functions, disparity activates a large number of regions in the brain of both humans and monkeys. Here, we review how disparity processing evolves along different regions of the ventral visual pathway of macaques, emphasizing research based on both correlational and causal techniques. We will discuss the progression in the ventral pathway from a basic absolute disparity representation to a more complex three-dimensional shape code. We will show that, in the course of this evolution, the underlying neuronal activity becomes progressively more bound to the global perceptual experience. We argue that these observations most probably extend beyond disparity processing per se, and pertain to object processing in the ventral pathway in general. We conclude by posing some important unresolved questions whose answers may significantly advance the field, and broaden its scope.This article is part of the themed issue 'Vision in our three-dimensional world'. © 2016 The Author(s).

    Neurological complications of human immunodeficiency virus (HIV) infection are a public health problem despite the availability of active antiretroviral therapies. The neuropathogenesis of HIV infection revolves around a complex cascade of events that include viral infection and glial immune activation, monocyte-macrophage brain infiltration, and secretion of a host of viral and cellular inflammatory and neurotoxic molecules. Although there is evidence that HIV-infected drug abusers experience more severe neurological disease, the biological basis for this finding is unknown. A scientific workshop organized by the National Institute on Drug Abuse (NIDA) was held on March 23-24, 2006 to address this question. The goal of the meeting was to bring together basic science and clinical researchers who are experts in NeuroAIDS, glial immunity, drugs of abuse, and/or pharmacology in order to find new approaches to understanding interactions between drug abuse and neuroAIDS. The format of the meeting was designed to stimulate open discussion and forge new multidisciplinary research collaborations. This report includes transcripts of active discussions and short presentations from invited participants. The presentations were separated into sections that included: Glial Biology, Inflammation, and HIV; Pharmacology, Neurotoxicology, and Neuroprotection; NeuroAIDS and Virology; and Virus-Drug and Immune-Drug Interactions. Research priorities were identified.

    Nepal has been receiving foreign aid since the early 1950s. Currently, the country's health care system is heavily dependent on aid, even for the provision of basic health services to its people. Globally, the mechanism for the dispersal of foreign aid is becoming increasingly complex. Numerous stakeholders are involved at various levels: donors, intermediary organisations, project-implementing partners and the beneficiaries, engaging not only in Nepal but also globally. To illustrate how branding and bidding occurs, and to discuss how this process has become increasingly vital in securing foreign aid to run MCH activities in Nepal. This paper is based on a qualitative study. The data collection method includes Key Informant Interviews, the review of relevant policy documents and secondary data, and finally field observation visits to four maternal and child health (MCH) projects, currently funded by foreign aid. Through these methods we planned to gain a comprehensive understanding of the aid dispersing mechanism, and the aid-securing strategies, used by organisations seeking funds to provide MCH services in Nepal. Study findings suggest that foreign aid for the provision of MCH services in Nepal is channeled increasingly to its beneficiaries, not through the Government system, but rather via various intermediary organisations, employing branding and bidding processes. These organisations adapt commercial models, seeking to justify their 'cost-effectiveness'. They argue that they are 'yielding good value for money', with short-term target oriented projects. This ethos is evident throughout the aid dispersing chain. Organisations use innovative ideas and intervention packages, branded internationally and nationally, and employ the appropriate language of commerce in their bid to secure funds. The paper raises an important question as to whether the current mechanisms of channeling foreign aid in the MCH sector, via intermediary organisations, can actually be cost

    A substantial body of literature exists about depth distribution of fish in oceans, lakes and reservoirs, but less is known about fish depth distribution in large rivers. Most of the emphasis on fish distributions in rivers has focused on longitudinal and latitudinal spatial distributions. Knowledge on depth distribution is necessary to understand species and community habitat needs. Considering this void, our goal was to identify patterns in fish benthic distribution along depth gradients in the Lower Mississippi River. Fish were collected over 14 years in depths down to 27 m. Fish exhibited non-random depth distributions that varied seasonally and according to species. Species richness was highest in shallow water, with about 50% of the 62 species detected no longer collected in water deeper than 8 m and about 75% no longer collected in water deeper than 12 m. Although richness was highest in shallow water, most species were not restricted to shallow water. Rather, most species used a wide range of depths. A weak depth zonation occurred, not as strong as that reported for deep oceans and lakes. Larger fish tended to occur in deeper water during the high-water period of an annual cycle, but no correlation was evident during the low-water period. The advent of landscape ecology has guided river research to search for spatial patterns along the length of the river and associated floodplains. Our results suggest that fish assemblages in large rivers are also structured vertically. 

  16. Focal Depth of the WenChuan Earthquake Aftershocks from modeling of Seismic Depth Phases

    After the 05/12/2008 great WenChuan earthquake in Sichuan Province of China, tens of thousands earthquakes occurred with hundreds of them stronger than M4. Those aftershocks provide valuable information about seismotectonics and rupture processes for the mainshock, particularly accurate spatial distribution of aftershocks is very informational for determining rupture fault planes. However focal depth can not be well resolved just with first arrivals recorded by relatively sparse network in Sichuan Province, therefore 3D seismicity distribution is difficult to obtain though horizontal location can be located with accuracy of 5km. Instead local/regional depth phases such as sPmP, sPn, sPL and teleseismic pP,sP are very sensitive to depth, and be readily modeled to determine depth with accuracy of 2km. With reference 1D velocity structure resolved from receiver functions and seismic refraction studies, local/regional depth phases such as sPmP, sPn and sPL are identified by comparing observed waveform with synthetic seismograms by generalized ray theory and reflectivity methods. For teleseismic depth phases well observed for M5.5 and stronger events, we developed an algorithm in inverting both depth and focal mechanism from P and SH waveforms. Also we employed the Cut and Paste (CAP) method developed by Zhao and Helmberger in modeling mechanism and depth with local waveforms, which constrains depth by fitting Pnl waveforms and the relative weight between surface wave and Pnl. After modeling all the depth phases for hundreds of events , we find that most of the M4 earthquakes occur between 2-18km depth, with aftershocks depth ranging 4-12km in the southern half of Longmenshan fault while aftershocks in the northern half featuring large depth range up to 18km. Therefore seismogenic zone in the northern segment is deeper as compared to the southern segment. All the aftershocks occur in upper crust, given that the Moho is deeper than 40km, or even 60km west of the

    The results of the studies to date indicate that the Basic Word Vocabulary Test provides a range of items in terms of item difficulty levels useful in printed form from about the third grade to the highest educational levels. Since pictorial and orally given vocabulary tests are used from about ages 2 to 8 years, further work should be done to extend the scale downward so that a single comprehensive vocabulary scale ranging from age 2 years to the highest level of verbal development is available for general use. Validation studies should also be conducted with other well-known intelligence tests so that scores can be compared. Alternate forms need to be developed to allow for longitudinal studies of growth and development. The use of a single standard of measurement of vocabulary development, suitable over a wide range of age and ability levels, by different investigators should materially aid in comparing results across studies and samples and lead to more consistent findings, advances in knowledge, and wider application of findings in practical circumstances, The findings presented in this report indicate that the Basic Word Vocabulary Test adequately measures basic word knowledge acquisition and development. The BWVT is suitable for evaluation of individuals and for use in making group comparisons in levels of basic word knowledge attainment, growth, and development.

    An airborne Sun photometer was used to measure optical depths in clear atmospheres between the appearances of broken stratus clouds, and the optical depths in the vicinity of smokes. Results show that (human) activities can alter the chemical and optical properties of background atmospheres to affect their spectral optical depths. Effects of water vapor adsorption on aerosol optical depths are apparent, based on data of the water vapor absorption band centered around 940 nm. Smoke optical depths show increases above the background atmosphere by up to two orders of magnitude. When the total optical depths measured through clouds were corrected for molecular scattering and gaseous absorption by subtracting the total optical depths measured through the background atmosphere, the resultant values are lower than those of the background aerosol at short wavelengths. The spectral dependence of these cloud optical depths is neutral, however, in contrast to that of the background aerosol or the molecular atmosphere.

    Purpose: To evaluate the clinical outcomes of implants placed using different types of computer-aided design/computer-aided manufacturing (CAD/CAM) surgical guides, including partially guided and totally guided templates, and determine the accuracy of these guides Materials and methods: In total, 111 implants were placed in 24 patients using CAD/CAM surgical guides. After implant insertion, the positions and angulations of the placed implants relative to those of the planned ones were determined using special software that matched pre- and postoperative computed tomography (CT) images, and deviations were calculated and compared between the different guides and templates. Results: The mean angular deviations were 1.72 ± 1.67 and 2.71 ± 2.58, the mean deviations in position at the neck were 0.27 ± 0.24 and 0.69 ± 0.66 mm, the mean deviations in position at the apex were 0.37 ± 0.35 and 0.94 ± 0.75 mm, and the mean depth deviations were 0.32 ± 0.32 and 0.51 ± 0.48 mm with tooth- and mucosa-supported stereolithographic guides, respectively (P < .05 for all). The mean distance deviations when partially guided (29 implants) and totally guided templates (30 implants) were used were 0.54 ± 0.50 mm and 0.89 ± 0.78 mm, respectively, at the neck and 1.10 ± 0.85 mm and 0.81 ± 0.64 mm, respectively, at the apex, with corresponding mean angular deviations of 2.56 ± 2.23° and 2.90 ± 3.0° (P > .05 for all). Conclusions: Tooth-supported surgical guides may be more accurate than mucosa-supported guides, while both partially and totally guided templates can simplify surgery and aid in optimal implant placement.

    The troposphere is the region of the atmosphere characterized by low static stability, vigorous diabatic mixing, and widespread condensational heating in clouds. Previous research has argued that in the tropics, the upper bound on tropospheric mixing and clouds is constrained by the rapid decrease with height of the saturation water vapor pressure and hence radiative cooling by water vapor in clear-sky regions. Here the authors contend that the same basic physics play a key role in constraining the vertical structure of tropospheric mixing, tropopause temperature, and cloud-top temperature throughout the globe. It is argued that radiative cooling by water vapor plays an important role in governing the depth and amplitude of large-scale dynamics at extratropical latitudes.

    To see how industry is responding to AIDS, an anonymous questionnaire survey was conducted on member companies (n = 407) of the chamber of commerce with 50 or more employees in three large cities in Okinawa, during February to March, 1994. Responses were obtained from 221. The questionnaire looked at type of industry, number of employees, number of business trips to foreign countries, specialists for health management, AIDS control, attitudes and actions taken toward infected persons and AIDS patients, etc. The main results were as follows; In 73 companies foreign business trips had been made. The rate of appointment of specialists in health management was below 50%. In 80% of the companies, AIDS control was not in place. About 1/2 of the companies responded that there was a need to grapple with AIDS control while 40% of the companies were undecided. The majority of the companies felt that there was no chance of their employees having HIV infection within five or six years. Many companies had no regulations for dealing with employees who are infected with HIV. From the survey, three points were made clear: 1. Industry does not have an adequate plan to deal with AIDS. 2. There is no awareness of a crisis. 3. There is insufficient dissemination of information regarding AIDS. HIV/AIDS is predicted to increase in industries in our country and management will be hard-pressed to deal with the intricate problems that arise. HIV/AIDS is not exclusively an individual problem, but should be the concern of industries and society as well.(ABSTRACT TRUNCATED AT 250 WORDS)

    2013-01-01

    Background Patient preference is one of the main components of clinical decision making, therefore leading to the development of patient decision aids. The goal of this study was to describe physicians’ and patients’ viewpoints on the barriers and limitations of using patient decision aids in Iran, their proposed solutions, and, the benefits of using these tools. Methods This qualitative study was conducted in 2011 in Iran by holding in-depth interviews with 14 physicians and 8 arthritis patient. Interviewees were selected through purposeful and maximum variation sampling. As an example, a patient decision aid on the treatment of knee arthritis was developed upon literature reviews and gathering expert opinion, and was presented at the time of interview. Thematic analysis was conducted to analyze the data by using the OpenCode software. Results The results were summarized into three categories and ten codes. The extracted categories were the perceived benefits of using the tools, as well as the patient-related and physician-related barriers in using decision aids. The following barriers in using patient decision aids were identified in this study: lack of patients and physicians’ trainings in shared decision making, lack of specialist per capita, low treatment tariffs and lack of an exact evaluation system for patient participation in decision making. Conclusions No doubt these barriers demand the health authorities’ special attention. Hence, despite patients and physicians’ inclination toward using patient decision aids, these problems have hindered the practical usage of these tools in Iran - as a developing country.

    HIV/AIDS is a major public health and social problem worldwide, and non-governmental organizations (NGOs) have played an irreplaceable role in HIV/AIDS prevention and control. At the present time, however, NGOs have not fully participated in HIV/AIDS prevention and control in China. As an emerging focus on international academic inquiry, social capital can provide a new perspective from which to promote the growth of NGOs. The Joint United Nations Program on HIV/AIDS (UNAIDS) recommends creating regional policies tailored to multiple and varying epidemics of HIV/AIDS. In order to provide evidence to policymakers, this paper described the basic information on NGOs and their shortage of social capital. This paper also compared the actual NGOs to "government-organized non-governmental organizations" (GONGOs). Results indicated that i) Chinese NGOs working on HIV/AIDS are short of funding and core members. GONGOs received more funding, had more core members, and built more capacity building than actual NGOs; ii) Almost half of the NGOs had a low level of trust and lacked a shared vision, networks, and support. The staff of GONGOs received more support from their organization than the staff of actual NGOs. Existing intra-organizational social capital among the staff of NGOs should be increased. Capacity building and policymaking should differentiate between actual NGOs and GONGOs. The relationship between social capital and organizational performance is a topic for further study.

    The science presented at the 21st International AIDS Conference in Durban, South Africa, in July 2016, addressed the state of the field across basic, clinical, prevention, law and policy and implementation science. The AIDS response has seen remarkable achievements in scientific advances, in translation of those advances into prevention, treatment and care for affected individuals and communities, and in large scale implementation - reaching 18 million people with antiviral therapy by mid-year 2016.

    Abstract Introduction: The science presented at the 21st International AIDS Conference in Durban, South Africa, in July 2016, addressed the state of the field across basic, clinical, prevention, law and policy and implementation science. Methods and Results: The AIDS response has seen remarkable achievements in scientific advances, in translation of those advances into prevention, treatment and care for affected individuals and communities, and in large scale implementation – reaching 18 million people with antiviral therapy by mid-year 2016. Yet incident HIV infections in adults remain stubbornly stable and are increasing in some regions and among adolescents and adults in some key populations, challenging current science, policy and programming. There have been important advances in both preventive vaccines and in cure research, but both areas require ongoing investment and innovation. Clinical research has flourished with new agents, regimens, delivery modes and diagnostics but has been challenged by aging and increasingly complex patient populations, long-term adherence challenges, co-infections and co-morbidities, and unresolved issues in TB management and epidemic control. It is an extraordinary period of innovation in prevention, yet the promise of new tools and combination approaches have yet to deliver epidemic HIV control. Conclusions: Proven interventions, most notably pre-exposure prophylaxis, PrEP, have been limited in rollout and impact. Treatment as prevention has the promise to improve clinical outcomes but remains uncertain as a prevention tool to reduce population-level HIV incidence. The improvement of legal, policy and human rights environments for those most at risk for HIV acquisition and most at risk for lack of access to essential services; sexual and gender minorities, sex workers of all genders, people who inject drugs, and prisoners and detainees remain among the greatest unmet needs in HIV/AIDS.

    Malawi has for a long time relied on agriculture for the generation of foreign exchange. Due to varied reasons like climate change, the Malawi government has, therefore, identified tourism as one way of boosting foreign exchange earnings and is already in the process of developing the sector especially in the area of ecotourism. However, tourism is associated with increasing prostitution, drug abuse and a whole range of other sexual and reproductive health (SRH) problems such as teenage pregnancies, HIV/AIDS and sexually transmitted infections (STIs). This paper examines the knowledge, attitudes, practices and behaviour as well as risk perceptions associated with HIV/AIDS, sexually transmitted infections and unwanted pregnancies among staff in the tourism industry and communities around tourist facilities in Malawi. The study was descriptive in nature and used both qualitative and quantitative research methods. The qualitative methods involved in-depth interviews and focus group discussions. The quantitative technique employed a survey of 205 purposively selected subjects from the tourism sector. The study concludes that people in the tourism sector are at high risk of HIV/AIDS, sexually transmitted infections and unwanted pregnancies and should be considered as a vulnerable group. The study further observes that this group of people has not adopted behaviours that can protect them from HIV/AIDS, sexually transmitted infections and unwanted pregnancies although there is high demand for voluntary counselling and testing (VCT) which offers a very good entry point for HIV prevention and treatment in the tourism sector. The study recommends that a comprehensive tourism policy covering tourists, employees and communities around tourist facilities is required. Such a policy should address the rights of HIV infected employees and the provision of prevention and treatment services for HIV/AIDS and STIs as well as a broad range of SRH and family planning services especially

    The natural ground surface carries texture information that extends continuously from one’s feet to the horizon, providing a rich depth resource for accurately locating an object resting on it. Here, we showed that the ground surface’s role as a reference frame also aids in locating a target suspended in midair based on relative binocular disparity. Using real world setup in our experiments, we first found that a suspended target is more accurately localized when the ground surface is visible and the observer views the scene binocularly. In addition, the increased accuracy occurs only when the scene is viewed for 5 sec rather than 0.15 sec, suggesting that the binocular depth process takes time. Second, we found that manipulation of the configurations of the texture-gradient and/or linear-perspective cues on the visible ground surface affects the perceived distance of the suspended target in midair. Third, we found that a suspended target is more accurately localized against a ground texture surface than a ceiling texture surface. This suggests that our visual system usesthe ground surface as the preferred reference frame to scale the distance of a suspended target according to its relative binocular disparity. PMID:25384237

    To investigate clinical manifestations and diagnostic difficulties in patients with HIV/AIDS in the practice of therapeutic units of a multidisciplinary hospital. The investigation included 65 HIV/AIDS patients admitted to the therapy units of a Saratov Regional clinical hospital in 2007 to 2011. The clinical features of HIV/AIDS, immunological status, and viral load were studied. The structure of the clinical manifestation of HIV/AIDS showed a preponderance of lung injury in 45 (69%) patients. There were hematological disorders in 38 (58%) patients and nephropathy in 33 (51 %); 11 (17%) patients were diagnosed with infective endocarditis. Rheumatic symptoms and syndromes mimicking HIV/AIDS were found in 10 (15.4%) patients. The degree of immune disorders was most severe in patients with pulmonary dissemination and rheumatic masks and mutually related to the rate of cutaneous manifestations. The specific features of lung injury, infective endocarditis, pulmonary hypertension, rheumatic symptoms, and kidney injury were discussed in HIV/AIDS patients having different causes for admission to specialized therapy units. In connection with the clinical polymorphism of HIV/AIDS, physicians of all specialties should be alert for the possible clinical manifestations of this disease to timely examine patients.

  13. Depth inpainting by tensor voting.

    2013-06-01

    Depth maps captured by range scanning devices or by using optical cameras often suffer from missing regions due to occlusions, reflectivity, limited scanning area, sensor imperfections, etc. In this paper, we propose a fast and reliable algorithm for depth map inpainting using the tensor voting (TV) framework. For less complex missing regions, local edge and depth information is utilized for synthesizing missing values. The depth variations are modeled by local planes using 3D TV, and missing values are estimated using plane equations. For large and complex missing regions, we collect and evaluate depth estimates from self-similar (training) datasets. We align the depth maps of the training set with the target (defective) depth map and evaluate the goodness of depth estimates among candidate values using 3D TV. We demonstrate the effectiveness of the proposed approaches on real as well as synthetic data.

    Understanding patients' knowledge and belief towards disease could play a vital role from an outcome perspective of disease management and HIV/AIDS patients are not exception to that. Qualitative methodology was used to explore Malaysian HIV/AIDS patients' perspectives on disease and status disclosure. A semi structured interview guide was used to interview the patients and a saturation point was reached after the 13th interview. All interviews were audio-recorded and subjected to a standard content analysis framework. Understandings and beliefs towards HIV/AIDS and Perspective on disease disclosures were two main themes derived from patients' data. Beliefs towards causes and cure emerged as sub-themes under disease understandings while reasons for disclosure and non-disclosure were resulted as main sub-themes under disease disclosure. Majority of patients apprehended HIV/AIDS and its causes to acceptable extent, there were elements of spirituality and lack of education involved with such understandings. Though beliefs existed that knowing status is better than being ignorant, fear of stigma and discrimination, social consequences and family emotions were found important elements linked to disease non-disclosure. The outcomes provided basic information about patients' perceptions towards disease and status disclosure among HIV/AIDS patients which can help in the designing and improvising existing strategies to enhance disease awareness and acceptance and will also serve as baseline data for future research further focusing on this subject. © 2014 John Wiley & Sons Ltd.

  15. Brainstem Encoding of Aided Speech in Hearing Aid Users with Cochlear Dead Region(s).

    PubMed

    2016-07-01

    Neural encoding of speech begins with the analysis of the signal as a whole broken down into its sinusoidal components in the cochlea, which has to be conserved up to the higher auditory centers. Some of these components target the dead regions of the cochlea causing little or no excitation. Measuring aided speech-evoked auditory brainstem response elicited by speech stimuli with different spectral maxima can give insight into the brainstem encoding of aided speech with spectral maxima at these dead regions. This research aims to study the impact of dead regions of the cochlea on speech processing at the brainstem level after a long period of hearing aid use. This study comprised 30 ears without dead regions and 46 ears with dead regions at low, mid, or high frequencies. For all ears, we measured the aided speech-evoked auditory brainstem response using speech stimuli of low, mid, and high spectral maxima. Aided speech-evoked auditory brainstem response was producible in all subjects. Responses evoked by stimuli with spectral maxima at dead regions had longer latencies and smaller amplitudes when compared with the control group or the responses of other stimuli. The presence of cochlear dead regions affects brainstem encoding of speech with spectral maxima perpendicular to these regions. Brainstem neuroplasticity and the extrinsic redundancy of speech can minimize the impact of dead regions in chronic hearing aid users.

  16. ToF-SIMS Depth Profiling Of Insulating Samples, Interlaced Mode Or Non-interlaced Mode?

    2014-11-01

    Dual beam depth profiling strategy has been widely adopted in ToF-SIMS depth profiling, in which two basic operation modes, interlaced mode and non-interlaced mode, are commonly used. Generally, interlaced mode is recommended for conductive or semi-conductive samples, whereas non-interlaced mode is recommended for insulating samples, where charge compensation can be an issue. Recent publications, however, show that the interlaced mode can be used effectively for glass depth profiling, despite the fact that glass is an insulator. In this study, we provide a simple guide for choosing between interlaced mode and non-interlaced mode for insulator depth profiling. Two representative cases aremore » presented: (1) depth profiling of a leached glass sample, and (2) depth profiling of a single crystal MgO sample. In brief, the interlaced mode should be attempted first, because (1) it may provide reasonable-quality data, and (2) it is time-saving for most cases, and (3) it introduces low H/C/O background. If data quality is the top priority and measurement time is flexible, non-interlaced mode is recommended because interlaced mode may suffer from low signal intensity and poor mass resolution. A big challenge is tracking trace H/C/O in a highly insulating sample (e.g., MgO), because non-interlaced mode may introduce strong H/C/O background but interlaced mode may suffer from low signal intensity. Meanwhile, a C or Au coating is found to be very effective to improve the signal intensity. Surprisingly, the best analyzing location is not on the C or Au coating, but at the edge (outside) of the coating.« less

    To investigate the residual stereo function of a group of 15 patients with strabismic amblyopia, by using motion-in-depth stimuli that allow discrimination of contributions from local disparity as opposed to those from local velocity mechanisms as a function of the rate of depth change. The stereo performance (percentage correct) was measured as a function of the rate of depth change for dynamic random dot stimuli that were either temporally correlated or uncorrelated. Residual stereoscopic function was demonstrated for motion in depth based on local disparity information in 2 of the 15 observers with strabismic amblyopia. The use of a neutral-density (ND) filter in front of the fixing eye enhanced motion-in-depth performance in four subjects randomly selected from the group that originally displayed only chance performance. This finding was true across temporal rate and for correlated and uncorrelated stimuli, suggesting that it was disparity based. The opposite occurred in a group of normal subjects. In a separate experiment, the hypothesis was that the beneficial effect of the ND filter is due to its contrast and/or mean luminance-reducing effects rather than any interocular time delay that it may introduce and that it is specific to motion-in-depth performance, as similar improvements were not found for static stereopsis. A small proportion of observers with strabismic amblyopia exhibit residual performance for motion in depth, and it is disparity based. Furthermore, some observers with strabismic amblyopia who do not display any significant stereo performance for motion in depth under normal binocular viewing may display above-chance stereo performance if the degree of interocular suppression is reduced. The authors term this phenomenon latent stereopsis.

    Gaining a deeper understanding of enzyme catalysis is of great practical and fundamental importance. Over the years it has become clear that despite advances made in experimental mutational studies, a quantitative understanding of enzyme catalysis will not be possible without the use of computer modeling approaches. While we believe that electrostatic preorganization is by far the most important catalytic factor, convincing the wider scientific community of this may require the demonstration of effective rational enzyme design. Here we make the point that the main current advances in enzyme design are basically advances in directed evolution and that computer aided enzyme design must involve approaches that can reproduce catalysis in well-defined test cases. Such an approach is provided by the empirical valence bond method. PMID:24814389

    This study evaluated the penetration depth of 2% chlorhexidine digluconate (CHX) into root dentinal tubules and the influence of passive ultrasonic irrigation (PUI) using a confocal laser scanning microscope (CLSM). Twenty freshly extracted anterior teeth were decoronated and instrumented using Mtwo rotary files up to size 40, 4% taper. The samples were randomly divided into two groups (n = 10), that is, conventional syringe irrigation (CSI) and PUI. CHX was mixed with Rhodamine B dye and was used as the final irrigant. The teeth were sectioned at coronal, middle and apical levels and viewed under CLSM to record the penetration depth of CHX. The data were statistically analyzed using Kruskal-Wallis and Mann-Whitney U tests. The mean penetration depths of 2% CHX in coronal, middle and apical thirds were 138 µm, 80 µm and 44 µm in CSI group, respectively, whereas the mean penetration depths were 209 µm, 138 µm and 72 µm respectively in PUI group. Statistically significant difference was present between CSI group and PUI group at all three levels (p < 0.01 for coronal third and p < 0.001 for middle and apical thirds). On intragroup analysis, both groups showed statistically significant difference among three levels (p < 0.001). Penetration depth of 2% CHX into root dentinal tubules is deeper in coronal third when compared to middle and apical third. PUI aided in deeper penetration of 2% CHX into dentinal tubules when compared to conventional syringe irrigation at all three levels.

    Many seabirds (gannets, pelicans, gulls, albatrosses) dive into water at high speeds (25 m/s) in order to capture underwater preys. Diving depths of 20 body lengths are reported in the literature. This value is much larger than the one achieved by men, which is typically of the order of 3. We study this difference by comparing the vertical impact of slender vs bluff bodies. We quantify the influence of wetting and of the geometry on the trajectory and discuss the different laws that govern the diving depth.

    This article describes the major changes in the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/ AIDS) epidemic in Italy, using data from the National AIDS Registry and from 5 local surveillance systems for new HIV diagnoses. From 1982 to 2001, 49,063 adults with AIDS were reported to the AIDS Registry. From 1988 to 2000, the 5 local systems reported 23,252 new HIV diagnoses. The AIDS incidence increased until 1995, followed by a progressive decrease. A decrease was also observed for the incidence of new HIV diagnoses after 1989, with an apparent stabilization after 1998. Most AIDS cases have been represented by intravenous drug users (IDU), yet since 1999 the percentage of cases attributable to sexual transmission has exceeded that for IDUs. Similarly, among new HIV diagnoses, the percentage of cases attributable to sexual transmission increased from 23.6% before 1993 to 58.5% in 2000. The percentage of people with AIDS who discovered their seropositivity no earlier than 6 months before AIDS diagnosis increased from 20.6% in 1996 to 48.8% in 2001. Although the incidence of both AIDS and new HIV diagnoses has declined, a possible resurgence of the epidemic cannot be ruled out, in light of various factors that could lead to an increasing number of living infected people.

    To examine the experiences of caregiving among Vietnamese family members of persons living with HIV/AIDS. As the number of persons living with HIV/AIDS increases, the need of family caregivers who can take responsibility for the home care of these persons increases. Vietnam has one of the fastest growing HIV epidemics in Asia. A descriptive cross-sectional study with quantitative and qualitative methods was used. A purposive sample of 104 family caregivers, both male and female, participated voluntarily by answering a questionnaire of caregiver burden, and 20 of them participated in in-depth interview. Female caregivers were mainly mothers and wives while male caregivers were mainly husbands, fathers and siblings. The largest group of family caregivers reported moderate to severe burden. There was no difference between genders in total caregiver burden, but there were several differences between older and younger caregivers in some items of caregiver burden. Five categories of experiences emerged: Different types of caregiving to persons living with HIV/AIDS, cultural and religious issues associated with caregiving, keeping secret to avoid stigma and discrimination, lack of knowledge about disease and provision of care, and fear, anxiety and frustration. Stigma and discrimination should be decreased by providing knowledge to the general public about HIV/AIDS, in particular about ways of transmission and protection. Special knowledge should be given to family caregivers to enable them to give care to persons living with HIV/AIDS at home. This could be done through culturally appropriate training/intervention programmes in which coping methods should be included. Support group interventions should also be carried through. The results obtained can be used as baseline information. Health care providers should consider gender, age and culture of family members of persons living with HIV/AIDS.

    International Monetary Fund (IMF) and World Bank structural adjustment programs (SAPs) imposed on developing nations in the 1980s inadvertently helped set the stage for the AIDS epidemic. These programs continue to hinder efforts to prevent HIV transmission. SAPs resulted in the following phenomena which place populations at risk of HIV infection: increased rural-urban migration of cheap labor sparked by a shift to an export-oriented economy, the development of transportation infrastructures in the 1980s to support the changed economy, increased migration and urbanization, and reduced government spending upon health and social services necessitated by the SAPs. For HIV transmission in developing countries to be substantially reduced, the SAP economic policies which may have promoted disease must be modified. An alternative development strategy must satisfy basic human needs such as food, housing, and transport; shift emphasis from the production of a small number of primary commodities for export to diversified agricultural production; support marginal producers and subsistence farmers; emphasize human resource development; end the top-down approach favored by the IMF and World Bank in favor of a truly cooperative development policy; alter the charters of the IMF and World Bank to permit the cancellation or restructuring of debt; and require AIDS Impact Reports of the IMF and World Bank.

    Could HIV/AIDS become a positive factor for a child's life? This contradiction is explored in this paper based on anthropological fieldwork and research in Brazil. I used participant observation and informal interviewing both with children living with HIV/AIDS and uninfected street children to obtain qualitative data. Brazil is known as a country leader in social responses towards the AIDS epidemic. Not only has access to antiretroviral medications been assured, but also a series of help networks guarantee that the human rights of HIV-infected people be respected. Children and adolescents benefit equally from these social gains. As such, many children born to HIV-positive women have reached adolescence and have 'normal' lives. This article explores the life experiences of children and adolescents infected by HIV and compares them to the life experiences of street children. Even though the AIDS epidemic is linked to death, infected children and adolescents dream about their lives and futures. Contradictorily, street children, who have not acquired the virus and are considered healthy from a biological stand point, have no prospective plans and answer without hope to questions about the future.

    This stakeholder assessment of HIV/AIDS service providing institutions in Argentina offers insights into the HIV/AIDS crisis in Spanish-speaking Latin America from an institutional level and makes recommendations for strengthening the work and functioning of these institutions. This stakeholder assessment was conducted to determine how HIV/AIDS prevention and management in Argentina affects and is affected by relevant HIV/AIDS institutions. Semi-structured qualitative interviews were conducted with 13 key leaders of organizations working in HIV/AIDS prevention in Buenos Aires including non-governmental, governmental, and academic institutions. Analyses of interviewee comments are presented according to four major themes: network connections, program resources, perceptions of success, and challenges. Key findings include the need for strengthening formal networks, increasing the involvement of other non-AIDS related social institutions in promoting HIV prevention, finding more sustainable funding options, working more effectively with the public sector to create policies and regulations favorable to the HIV/AIDS field, and addressing the lack of perceived susceptibility to HIV/AIDS in Argentine culture. From leaders' comments, recommendations are made for strengthening the HIV/AIDS network among key institutions including adapting the UNAIDS "Three Ones" principal to create one crosssector office responsible for coordinating HIV/AIDS work, formalizing agreements with institutions outside of Buenos Aires, increasing the role of schools in HIV/AIDS awareness, and designing programs that address lack of perceived susceptibility to HIV/AIDS among Argentines.

    Shared decision making is essential to patient centered care, but can be difficult for busy clinicians to implement into practice. Tools have been developed to aid in shared decision making and embedded in electronic medical records (EMRs) to facilitate use. This study was undertaken to explore the patterns of use and barriers and facilitators to use of two decision aids, the Statin Choice Decision Aid (SCDA) and the Diabetes Medication Choice Decision Aid (DMCDA), in primary care practices where the decision aids are embedded in the EMR. A survey exploring factors that influenced use of each decision aid was sent to eligible primary care clinicians affiliated with the Mayo Clinic in Rochester, MN. Survey data was collected and clinician use of each decision aid via links from the EMR was tracked. The survey response rate was 40% (105/262). Log file data indicated 51% of clinicians used the SCDA and 9% of clinicians used the DMCDA. Reasons for lack of use included lack of knowledge of the EMR link, not finding the decision aids helpful, and time constraints. Survey responses indicated that use of the tool as intended was low, with many clinicians only discussing decision aid topics that they found relevant. Although guidelines for both the treatment of blood cholesterol with a statin and for the treatment of hyperglycemia in type 2 diabetes recommend shared decision making, tools that facilitate shared decision making are not routinely used even when embedded in the EMR. Even when decision aids are used, their use may not reflect patient centered care.

    2015-01-01

    The depth-differentiation hypothesis proposes that the bathyal region is a source of genetic diversity and an area where there is a high rate of species formation. Genetic differentiation should thus occur over relatively small vertical distances, particularly along the upper continental slope (200–1000 m) where oceanography varies greatly over small differences in depth. To test whether genetic differentiation within deepwater octocorals is greater over vertical rather than geographical distances, Callogorgia delta was targeted. This species commonly occurs throughout the northern Gulf of Mexico at depths ranging from 400 to 900 m. We found significant genetic differentiation (FST = 0.042) across seven sites spanning 400 km of distance and 400 m of depth. A pattern of isolation by depth emerged, but geographical distance between sites may further limit gene flow. Water mass boundaries may serve to isolate populations across depth; however, adaptive divergence with depth is also a possible scenario. Microsatellite markers also revealed significant genetic differentiation (FST = 0.434) between C. delta and a closely related species, Callogorgia americana, demonstrating the utility of microsatellites in species delimitation of octocorals. Results provided support for the depth-differentiation hypothesis, strengthening the notion that factors covarying with depth serve as isolation mechanisms in deep-sea populations.

    Introduction  Neural encoding of speech begins with the analysis of the signal as a whole broken down into its sinusoidal components in the cochlea, which has to be conserved up to the higher auditory centers. Some of these components target the dead regions of the cochlea causing little or no excitation. Measuring aided speech-evoked auditory brainstem response elicited by speech stimuli with different spectral maxima can give insight into the brainstem encoding of aided speech with spectral maxima at these dead regions. Objective  This research aims to study the impact of dead regions of the cochlea on speech processing at the brainstem level after a long period of hearing aid use. Methods  This study comprised 30 ears without dead regions and 46 ears with dead regions at low, mid, or high frequencies. For all ears, we measured the aided speech-evoked auditory brainstem response using speech stimuli of low, mid, and high spectral maxima. Results  Aided speech-evoked auditory brainstem response was producible in all subjects. Responses evoked by stimuli with spectral maxima at dead regions had longer latencies and smaller amplitudes when compared with the control group or the responses of other stimuli. Conclusion  The presence of cochlear dead regions affects brainstem encoding of speech with spectral maxima perpendicular to these regions. Brainstem neuroplasticity and the extrinsic redundancy of speech can minimize the impact of dead regions in chronic hearing aid users. PMID:27413404

    Previous literature suggests that increasing numbers of development aid donors can reduce aid effectiveness but this has not been tested in the health sector, which has experienced substantial recent growth in aid volume and number of donors. Based on annual data for 1995-2010 on 139 low- and middle-income countries that received health sector aid from donors reporting to the OECD's Creditor Reporting System, the study used two-step system generalized method of moments regression models to test whether the number of health aid donors and an index of health aid donor fragmentation affect health services (measured by DTP3 immunization rate) or health outcomes (measured by infant mortality rate) for three subsectors of health aid. For total health aid and for the general and basic health aid subsector, controlling for economic and political conditions, increases in the number of donors were associated with increases in DTP3 immunization rate and reductions in infant mortality while increases in the donor fragmentation index were associated with decreases in DTP3 immunization rate and increases in infant mortality, though none of these relationships were statistically significant. For the population and reproductive health aid subsector, a one percent increase in the number of donors was associated with a 0.23 percent decrease in DTP3 immunization ( P <  0.01) while a one percent increase in donor fragmentation was associated with a 0.54 percent increase in DTP3 immunization rate ( P <  0.01); associations with infant mortality rates for this subsector were similar to those for total health aid. The results do not provide clear evidence in support of the hypothesis that donor proliferation negatively impacts development results in the health sector. Aid effectiveness policy prescriptions should distinguish responses to donor proliferation versus donor fragmentation and be adapted to specific subsectors of health aid. © The Author 2016.

    HIV/AIDS is a global problem with an estimated 40 million infected people. In less than two years, this figure will leap to 100 million according to the World Health Organisation (WHO). By 2005, 65 million people will be infected. Half of the number of people in this group will be under 25 years old, and will die before they reach the age of 35. In a South African study done by the Human Science Research Council and published in 2003, regarding the impact of HIV/AIDS on the health sector, the findings were that 15% of health workers in public and private hospitals tested positive for HIV antibodies. Together with these facts above it was found that 46.2 percent of patients served in medical and paediatric wards tested positive for HIV. These factors have major implication for staffing in the future and the role of the nurse manager in South Africa. To explore the management of HIV/AIDS in the workplace of nurses in selected health services in KwaZulu-Natal. This research was part of a greater study on the exploration of the presence of caring as part of nursing management. THE METHODOLOGY: The qualitative research approach was used with a phenomenological design, which ensured that the richness and the complexities are reflected in the study. The data was collected by means of an open-ended question to nurse managers during an interview. The first question posed was; How do you or your services care for nurses in this hospital? Secondly nurse managers were asked, To explain their role in caring for HIV/AIDS positive nurses on their staff establishment. A qualitative analysis of the interviews with nurse managers indicated that they rate HIV/AIDS issues as an important part of their management task. Four main themes were identified, namely HIV/AIDS, counselling, dying of AIDS and funerals. Rich descriptions of these themes are given in this paper. Nurse managers in the health services are managing HIV/AIDS affected nurses, but are doing so without any formal policy

    This study analyzes the concepts displayed by rural men in the Zona da Mata region in the State of Pernambuco, Brazil, concerning their sexual practices and STD/AIDS prevention. The study adopts a qualitative methodology, having interviewed 22 men According to the interviews, their first sexual intercourse is characterized as a learning experience and is sometimes marked by violence. They make a distinction between the "woman at home" and "street women"; they acknowledge women's sexual desire and value reciprocity in sexual relations, differentiating between the kinds of sex they have with different categories of women. Seven men report homoerotic experiences during adolescence, which they ascribe to immaturity, not affecting their heterosexual identity. Condom use, perceived in a negative light, is inconstant and irregular, inversely proportional to knowing the female partner. STDs in general inspire little fear, while AIDS is associated with death; the interviewees do not see themselves at risk of acquiring HIV. Ambiguities in the men's discourse, together with a basically ineffective approach by health services and preventive campaigns, reveal a high level of exposure to the risk of contracting STDs/AIDS among the interviewees and their female or male partners.

    Poor survival rates after cardiac arrest can partly be explained by poor basic life support skills in medical professionals. This study aimed to assess quality of basic life support in medical students and paramedics. We conducted a prospective observational study with 100 early medical students (group A), 100 late medical students (group B) and 100 paramedics (group C), performing a 20-minute basic life support simulation in teams of two. Average frequency and absolute number of chest compressions per minute (mean (±SD)), chest decompression (millimetres of compression remaining, mean (±SD)), hands-off-time (seconds/minute, mean (±SD)), frequency of switching positions between ventilation and chest compression (per 20 minutes) and rate of sufficient compressions (depth ≥50mm) were assessed as quality parameters of CPR. In groups A, B and C the rates of sufficiently deep chest compressions were 56%, 42% and 52%, respectively, without significant differences. Male gender and real-life CPR experience were significantly associated with deeper chest compression. Frequency and number of chest compressions were within recommended goals in at least 96% of all groups. Remaining chest compressions were 6 mm (±2), 6 mm (±2) and 5 mm (±2) with a significant difference between group A and C (p=0.017). Hands-off times were 6s/min (±1), 5s/min (±1) and 4s/min (±1), which was significantly different across all three groups. Overall, paramedics tended to show better quality of CPR compared to medical students. Though, chest compression depth as an important quality characteristic of CPR was insufficient in almost 50% of participants, even in well trained paramedics. Therefore, we suggest that an effort should be made to find better ways to educate health care professionals in BLS.
