2015-06-01

Electives are part of most Western medical school curricula. It is estimated that each year 3000-4000 undergraduate medical students from the UK alone undertake an elective in a developing country. The impact of these electives has given some cause for concern, but the views of elective hosts are largely missing from the debate. The purpose of this study was to evaluate the organisation, outcomes and impacts of medical electives in sub-Saharan Africa from a host perspective. A qualitative analysis of 14 semi-structured interviews with elective hosts at seven elective sites in Malawi, Zambia and Tanzania was carried out. A framework analysis approach was used to analyse 483 minutes of audio-recorded data. Hosts were committed to providing elective experiences but their reasons for doing so varied considerably, in particular between urban or teaching hospitals and rural or mission hospitals. Nurturing a group of professionals who will understand the provision of health care from a global perspective was the main reason reported for hosting an elective, along with generating potential future staff. Hosts argued that the quality of supervision should be judged according to local context. Typical concerns cited in the literature with reference to clinical activities, safety and ethics did not emerge as issues for these hosts. However, in under-resourced clinical contexts, the training of local students sometimes had to take priority. Electives could be improved with greater student preparation and some contribution from sending institutions to support teaching, supervision or patient care. The challenge to both students and their sending institutions is to progress towards giving something proportionate back in return for the learning experiences received. There is clearly room to improve electives from the hosts' perspective, but individually host institutions lack the opportunity or ability to achieve change. © 2015 John Wiley & Sons Ltd.

Obstetric fistulae in West Africa: patient perspectives.

PubMed

Nathan, Lisa M; Rochat, Charles H; Grigorescu, Bogdan; Banks, Erika

2009-05-01

The objective of this study is to gain insight into the nature of obstetric fistulae in Africa through patient perspectives. At l'Hôpital Saint Jean de Dieu in Tanguieta, Benin, 37 fistula patients underwent structured interviews about fistula cause, obstacles to medical care, prevention, and reintegration by 2 physicians via interpreters. The majority of participants (43%) thought their fistulae were a result of trauma from the operative delivery. Lack of financial resources (49%) was the most commonly reported obstacle to care, and prenatal care (38%) was most frequently reported as an intervention that may prevent obstetric fistulae. The majority (49%) of the participants requested no further reintegration assistance aside from surgery. Accessible emergency obstetric care is necessary to decrease the burden of obstetric fistulae in Africa. This may be accomplished through increased and improved health care facilities and education of providers and patients.

Venus - 3D Perspective View of Maat Mons

NASA Technical Reports Server (NTRS)

1991-01-01

Maat Mons is displayed in this three-dimensional perspective view of the surface of Venus. The viewpoint is located 560 kilometers (347 miles) north of Maat Mons at an elevation of 1.7 kilometers (1 mile) above the terrain. Lava flows extend for hundreds of kilometers across the fractured plains shown in the foreground, to the base of Maat Mons. The view is to the south with Maat Mons appearing at the center of the image on the horizon. Maat Mons, an 8-kilometer (5 mile) high volcano, is located at approximately 0.9 degrees north latitude, 194.5 degrees east longitude. Maat Mons is named for an Egyptian goddess of truth and justice. Magellan synthetic aperture radar data is combined with radar altimetry to develop a three-dimensional map of the surface. The vertical scale in this perspective has been exaggerated 22.5 times. Rays cast in a computer intersect the surface to create a three-dimensional perspective view. Simulated color and a digital elevation map developed by the U.S. Geological Survey, are used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The image was produced at the JPL Multimission Image Processing Laboratory.

A Model of Manual Control with Perspective Scene Viewing

NASA Technical Reports Server (NTRS)

Sweet, Barbara Townsend

2013-01-01

A model of manual control during perspective scene viewing is presented, which combines the Crossover Model with a simpli ed model of perspective-scene viewing and visual- cue selection. The model is developed for a particular example task: an idealized constant- altitude task in which the operator controls longitudinal position in the presence of both longitudinal and pitch disturbances. An experiment is performed to develop and vali- date the model. The model corresponds closely with the experimental measurements, and identi ed model parameters are highly consistent with the visual cues available in the perspective scene. The modeling results indicate that operators used one visual cue for position control, and another visual cue for velocity control (lead generation). Additionally, operators responded more quickly to rotation (pitch) than translation (longitudinal).

Challenges in biobank governance in Sub-Saharan Africa.

PubMed

Staunton, Ciara; Moodley, Keymanthri

2013-09-11

Biological sample and data transfer within and out of Africa is steeped in controversy With the H3Africa project now aiming to establish biobanks in Africa, it is essential that there are ethical and legal governance structures in place to oversee the operation of these biobanks. Such governance is essential to ensuring that donors are protected, that cultural perspectives are respected and that researchers have a ready availability of ethically sourced biological samples. A literature review of all legislation, regulations, guidelines and standard operating procedures on informed consent, confidentiality and the transfer of biological samples amongst countries in Sub-Saharan Africa was conducted. In addition, an examination of the websites of departments of health and national ethics committees was performed. Researchers and research ethics scholars in the field in various African countries were contacted for assistance. A literature review of all studies examining participants views on issues related to biobanking in Africa was carried out and five separate studies were found. It was found that biobanking guidelines differ substantially across Sub-Saharan Africa regarding biobanking and often conflicted across borders. This has the potential to negatively impact collaboration. Furthermore, the guidelines in place often do not recognise the ethical difficulties arising from the transfer of biological samples and are unsuitable to regulate biobanks. Additionally, there is insufficient research into the views of research participants and stakeholders on the use of biological /samples. Collaboration is necessary to ensure the success of biobanking projects in Africa. To achieve this, there should be some harmonization of guidelines across Africa which would aid in transferring biological samples across borders. These guidelines should reflect the unique ethical issues arising out of the storage and secondary uses of biological samples. Finally, further research into

Sapas Mons is displayed in the center of this computer-generated three-dimensional perspective view of the surface of Venus. The viewpoint is located 527 kilometers (327 miles) northwest of Sapas Mons at an elevation of 4 kilometers (2.5 miles) above the terrain. Lava flows extend for hundreds of kilometers across the fractured plains shown in the foreground to the base of Sapas Mons. The view is to the southeast with Sapas Mons appearing at the center with Maat Mons located in the background on the horizon. Sapas Mons, a volcano 400 kilometers (248 miles) across and 1.5 kilometers (0.9 mile) high is located at approximately 8 degrees north latitude, 188 degrees east longitude, on the western edge of Atla Regio. Its peak sits at an elevation of 4.5 kilometers (2.8 miles) above the planet's mean elevation. Sapas Mons is named for a Phoenician goddess. The vertical scale in this perspective has been exaggerated 10 times. Rays cast in a computer intersect the surface to create a three-dimensional perspective view. Simulated color and a digital elevation map developed by the U.S. Geological Survey are used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The image was produced by the Solar System Visualization project and the Magellan Science team at the JPL Multimission Image Processing Laboratory and is a single frame from a video released at the April 22, 1992 news conference.

California's state capitol, Sacramento, can be seen clustered along the American and Sacramento Rivers in this computer-generated perspective viewed from the west. Folsom Lake is in the center and the Sierra Nevada is above, with the edge of Lake Tahoe just visible at top center.

This 3-D perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced color Landsat 5satellite image. Topographic expression is exaggerated two times.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and will substantially help in analyzing the large and growing Landsat image archive.

Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR)that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise, Washington, D.C.

Perspective View, San Andreas Fault

NASA Technical Reports Server (NTRS)

2000-01-01

The prominent linear feature straight down the center of this perspective view is California's famous San Andreas Fault. The image, created with data from NASA's Shuttle Radar Topography Mission (SRTM), will be used by geologists studying fault dynamics and landforms resulting from active tectonics. This segment of the fault lies west of the city of Palmdale, Calif., about 100 kilometers (about 60 miles) northwest of Los Angeles. The fault is the active tectonic boundary between the North American plate on the right, and the Pacific plate on the left. Relative to each other, the Pacific plate is moving away from the viewer and the North American plate is moving toward the viewer along what geologists call a right lateral strike-slip fault. Two large mountain ranges are visible, the San Gabriel Mountains on the left and the Tehachapi Mountains in the upper right. Another fault, the Garlock Fault lies at the base of the Tehachapis; the San Andreas and the Garlock Faults meet in the center distance near the town of Gorman. In the distance, over the Tehachapi Mountains is California's Central Valley. Along the foothills in the right hand part of the image is the Antelope Valley, including the Antelope Valley California Poppy Reserve. The data used to create this image were acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000.

This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat satellite image over an SRTM elevation model. Topography is exaggerated 1.5 times vertically. The Landsat image was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota.

SRTM uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space

Relative to each other, the Pacific plate is moving away from the viewer and the North American plate is moving toward the viewer along what geologists call a right lateral strike-slip fault. This area is at the junction of two large mountain ranges, the San Gabriel Mountains on the left and the Tehachapi Mountains on the right. Quail Lake Reservoir sits in the topographic depression created by past movement along the fault. Interstate 5 is the prominent linear feature starting at the left edge of the image and continuing into the fault zone, passing eventually over Tejon Pass into the Central Valley, visible at the upper left.

Venus - 3D Perspective View of Eistla Regio

NASA Technical Reports Server (NTRS)

1991-01-01

A portion of western Eistla Regio is displayed in this three-dimensional perspective view of the surface of Venus. The viewpoint is located 1,310 kilometers (812 miles) southwest of Gula Mons at an elevation of 0.78 kilometer (0.48 mile). The view is to the northeast with Gula Mons appearing on the horizon. Gula Mons, a 3 kilometer (1.86 mile) high volcano, is located at approximately 22 degrees north latitude, 359 degrees east longitude. The impact crater Cunitz, named for the astronomer and mathematician Maria Cunitz, is visible in the center of the image. The crater is 48.5 kilometers (30 miles) in diameter and is 215 kilometers (133 miles) from the viewer's position. Magellan synthetic aperture radar data is combined with radar altimetry to develop a three-dimensional map of the surface. Rays cast in a computer intersect the surface to create a three-dimensional perspective view. Simulated color and a digital elevation map developed by the U.S. Geological Survey, are used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The image was produced at the JPL Multimission Image Processing Laboratory and is a single frame from a video released at the March 5, 1991, JPL news conference.

Implementing Health Financing Reforms in Africa: Perspectives of Health System Stewards.

PubMed

Achoki, Tom; Lesego, Abaleng

A majority of health systems in the sub-Saharan Africa region are faced with multiple competing priorities amid pressing resource constraints. Health financing reforms, characterized by expansion of health insurance coverage, have been proposed as promising in the quest to improve health sustainably. However, in many countries where these measures are being attempted, their broader implications have not been fully appreciated. This study was based on perspectives of 37 health system stewards from Botswana who were interviewed in order to understand opportunities and challenges that would result in the quest to expand health insurance coverage in the country. Thematic synthesis of their perspectives, focusing on the key aspects of the health systems, was done in order to draw informative lessons that could be applicable to a broader set of low- and middle-income countries. Health systems attempting to expand health insurance coverage would be faced with various opportunities and challenges that have implications on performance. By increasing the pool of resources available to spend on health, health insurance would afford health systems the opportunity to increase population access to and use of health services. However, if unchecked, this could also translate to uncontrolled demand for expensive medicines and other health technologies, leading to cost escalation and inefficiencies within the system. Therefore, the success of any health financing reform is dependent on embracing sound policies, regulations, and accountability measures. Health financing reforms have broader implications to health system performance that should be fully appreciated and anticipated before implementation. Therefore, health system leaders who are keen to improve health must view any health financing reforms through the broader framework of the health system framework in order to make progress.

Owning the body in the mirror: The effect of visual perspective and mirror view on the full-body illusion

PubMed Central

Preston, Catherine; Kuper-Smith, Benjamin J.; Henrik Ehrsson, H.

2015-01-01

Mirrors allow us to view our own body from a third-person (observer) perspective. However, how viewing ourselves through a mirror affects central body representations compared with true third-person perspective is not fully understood. Across a series of experiments, multisensory full-body illusions were used to modulate feelings of ownership over a mannequin body that was viewed from a third-person perspective through a mirror, from a third-person perspective without a mirror, and from a first-person perspective. In contrast to non-mirror third-person perspective, synchronously touching the participant’s actual body and the mannequin body viewed in the mirror elicited strong feelings of ownership over the mannequin and increased physiological responses to the mannequin being threatened compared to the equivalent asynchronous (non-ownership) control condition. Subjective reports of ownership viewing the mannequin through a mirror were also statistically equivalent to those following the first-person perspective illusion. These findings suggest that mirrors have a special role for viewing the self. The results also support the importance of egocentric reference frames for body ownership and suggest that mirror reflections of one’s own body are related to peripersonal space, which enables updating of central body representations.

Perspective View with Landsat Overlay, Mount Shasta, Calif.

NASA Technical Reports Server (NTRS)

2002-01-01

At more than 4,300 meters (14,000 feet ), Mount Shasta is California's tallest volcano and part of the Cascade chain of volcanoes extending south from Washington. This computer-generated perspective viewed from the west also includes Shastina, a slightly smaller volcanic cone left of Shasta's summit and Black Butte, another volcano in the right foreground.

This 3-D perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced color Landsat 5satellite image. Topographic expression is exaggerated two times.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and will substantially help in analyzing the large and growing Landsat image archive.

Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR)that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise,Washington, D.C.

Perspective View, Kamchatka Peninsula, Russia

NASA Technical Reports Server (NTRS)

2000-01-01

This perspective view shows the western side of the volcanically active Kamchatka Peninsula, Russia. The data are from the first C-band mapping swath of the Shuttle Radar Topography Mission (SRTM). In the foreground is the broad, flat floodplain of the Amanina River, shown in blue. In background of the image is the Sredinnyy Khrebet, the volcanic mountain range that makes up the 3spine2 of the peninsula. The cluster of hills in the upper right is a field of small dormant volcanoes. High resolution SRTM topographic data will be used by geologists to study how volcanoes form and understand the hazards posed by future eruptions.

This shaded relief perspective view was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. Colors show the elevation as measured by SRTM. Colors range from blue at the lowest elevations to white at the highest elevations. This image contains about 2300 meters (7500 feet) of total relief. To emphasize subtle differences in topography, the relief is exaggerated by a factor of 5.

The Shuttle Radar Topography Mission (SRTM), launched on February 11,2000, uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. The mission is designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, an additional C-band imaging antenna and improved tracking and navigation devices.

Venus - 3D Perspective View of Maat Mons

NASA Technical Reports Server (NTRS)

1992-01-01

Maat Mons is displayed in this computer generated three-dimensional perspective of the surface of Venus. The viewpoint is located 634 kilometers (393 miles) north of Maat Mons at an elevation of 3 kilometers (2 miles) above the terrain. Lava flows extend for hundreds of kilometers across the fractured plains shown in the foreground, to the base of Maat Mons. The view is to the south with the volcano Maat Mons appearing at the center of the image on the horizon and rising to almost 5 kilometers (3 miles) above the surrounding terrain. Maat Mons is located at approximately 0.9 degrees north latitude, 194.5 degrees east longitude with a peak that ascends to 8 kilometers (5 miles) above the mean surface. Maat Mons is named for an Egyptian Goddess of truth and justice. Magellan synthetic aperture radar data is combined with radar altimetry to develop a three-dimensional map of the surface. The vertical scale in this perspective has been exaggerated 10 times. Rays cast in a computer intersect the surface to crate a three-dimensional perspective view. Simulated color and a digital elevation map developed by the U.S. Geological Survey are used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The image was produced by the Solar System Visualization project and the Magellan Science team at the JPL Multimission Image Processing Laboratory and is a single frame from a video released at the April 22, 1992 news conference.

Perspective View with Landsat Overlay, Los Angeles Basin

NASA Technical Reports Server (NTRS)

2002-01-01

Most of Los Angeles is visible in this computer-generated north-northeast perspective viewed from above the Pacific Ocean. In the foreground the hilly Palos Verdes peninsula lies to the left of the harbor at Long Beach, and in the middle distance the various communities that comprise the greater Los Angeles area appear as shades of grey and white. In the distance the San Gabriel Mountains rise up to separate the basin from the Mojave Desert, which can be seen near the top of the image.

This 3-D perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced color Landsat 5satellite image mosaic. Topographic expression is exaggerated one and one-half times.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and will substantially help in analyzing the large and growing Landsat image archive.

Perspective View, Mt. Etna, Italy

NASA Image and Video Library

2002-11-01

Italy's Mount Etna is the focus of this perspective view made from an Advanced Spaceborne Thermal and Emission Radiometer (ASTER) image from NASA's Terra spacecraft overlaid on Shuttle Radar Topography Mission (SRTM) topography. The image is looking south with dark lava flows from the 1600's (center) to 1981 (long flow at lower right) visible in the foreground and the summit of Etna above. The city of Catania is barely visible behind Etna on the bay at the upper left. In late October 2002, Etna erupted again, sending lava flows down the north and south sides of the volcano. The north flows are near the center of this view, but the ASTER image is from before the eruption. In addition to the terrestrial applications of these data for understanding active volcanoes and hazards associated with them such as lava flows and explosive eruptions, geologists studying Mars find these data useful as an analog to martian landforms and geologic processes. In late September 2002, a field conference with the theme of Terrestrial Analogs to Mars focused on Mount Etna, allowing Mars geologists to see in person the types of features they can only sample remotely. http://photojournal.jpl.nasa.gov/catalog/PIA03371

Perspective view, Landsat overlay Pasadena, California

NASA Technical Reports Server (NTRS)

2000-01-01

This image shows a perspective view of the area around Pasadena, California, just north of Los Angeles. The cluster of hills surrounded by freeways on the left is the Verdugo Hills, which lie between the San Gabriel Valley in the foreground and the San Fernando Valley in the upper left. The San Gabriel Mountains are seen across the top of the image, and parts of the high desert near the city of Palmdale are visible along the horizon on the right. Several urban features can be seen in the image. NASA's Jet Propulsion Laboratory (JPL) is the bright cluster of buildings just right of center; the flat tan area to the right of JPL at the foot of the mountains is a new housing development devoid of vegetation. Two freeways (the 210 and the 134) cross near the southeastern end of the Verdugo Hills near a white circular feature, the Rose Bowl. The commercial and residential areas of the city of Pasadena are the bright areas clustered around the freeway. These data will be used for a variety of applications including urban planning and natural hazard risk analysis.

This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat satellite image over an SRTM elevation model. Topography is exaggerated 1.5 times vertically. The Landsat image was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota.

Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11,2000.

Perspective View with Landsat Overlay, Costa Rica

NASA Technical Reports Server (NTRS)

2002-01-01

This perspective view shows the Caribbean coastal plain of Costa Rica, with the Cordillera Central rising in the background and the Pacific Ocean in the distance. The prominent river in the center of the image is the Rio Sucio, which merges with the Rio Sarapiqui at the bottom of the image and eventually joins with Rio San Juan on the Nicaragua border.

Like much of Central America, Costa Rica is generally cloud covered so very little satellite imagery is available. The ability of the Shuttle Radar Topography Mission (SRTM) instrument to penetrate clouds and make three-dimensional measurements will allow generation of the first complete high-resolution topographic map of the entire region. These data were used to generate the image.

This three-dimensional perspective view was generated using elevation data from SRTM and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated two times.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive.

HIV cure research in South Africa: a preliminary exploration of stakeholder perspectives.

PubMed

Moodley, Keymanthri; Staunton, Ciara; de Roubaix, Malcolm; Cotton, Mark

2016-01-01

Innovative strategies for HIV cure are in development and research studies are being designed and planned globally. South Africa is no exception. However, little is known about stakeholders' knowledge, understanding and expectations of future cure research. This study aimed to obtain in-depth qualitative insights into stakeholder perspectives at this formative stage of HIV cure research. Fifteen stakeholders were interviewed in an HIV research clinic in the Western Cape, South Africa with their consent. Interviews were transcribed verbatim and analysed using thematic content analysis. Broad themes that emerged included the meaning of cure, awareness of HIV cure research, risks and benefits of such research. General awareness and understanding of HIV cure research was lower than expected. Some participants expressed a fatalistic attitude to HIV and described it as an "end-time illness" with no prospect of cure. In general, HIV cure research was regarded as risky - biologically psychologically and socially. If study designs were to include treatment interruption, participants would comply only if success was guaranteed. Given these perceptions of HIV cure research, significant challenges to consent processes and participant recruitment can be anticipated. Authentic community engagement and intensive educational interventions will be necessary prior to future cure research in South Africa.

The views of key leaders in South Africa on implementation of family medicine: critical role in the district health system.

2014-06-25

Integrated team-based primary care is an international imperative. This is required more so in Africa, where fragmented verticalised care dominates. South Africa is trying to address this with health reforms, including Primary Health Care Re-engineering. Family physicians are already contributing to primary care despite family medicine being only fully registered as a full specialty in South Africa in 2008. However the views of leaders on family medicine and the role of family physicians is not clear, especially with recent health reforms. The aim of this study was to understand the views of key government and academic leaders in South Africa on family medicine, roles of family physicians and human resource issues. This was a qualitative study with academic and government leaders across South Africa. In-depth interviews were conducted with sixteen purposively selected leaders using an interview guide. Thematic content analysis was based on the framework method. Whilst family physicians were seen as critical to the district health system there was ambivalence on their leadership role and 'specialist' status. National health reforms were creating both threats and opportunities for family medicine. Three key roles for family physicians emerged: supporting referrals; clinical governance/quality improvement; and providing support to community-oriented care. Respondents' urged family physicians to consolidate the development and training of family physicians, and shape human resource policy to include family physicians. Family physicians were seen as critical to the district health system in South Africa despite difficulties around their precise role. Whilst their role was dominated by filling gaps at district hospitals to reduce referrals it extended to clinical governance and developing community-oriented primary care - a tall order, requiring strong teamwork. Innovative team-based service delivery is possible despite human resource challenges, but requires family

First Simultaneous Views of the Axial and Lateral Perspectives of a Coronal Mass Ejection

NASA Astrophysics Data System (ADS)

Cabello, I.; Cremades, H.; Balmaceda, L.; Dohmen, I.

2016-08-01

The different appearances exhibited by coronal mass ejections (CMEs) are believed to be in part the result of different orientations of their main axis of symmetry, consistent with a flux-rope configuration. There are observational reports of CMEs seen along their main axis (axial perspective) and perpendicular to it (lateral perspective), but no simultaneous observations of both perspectives from the same CME have been reported to date. The stereoscopic views of the telescopes onboard the Solar-Terrestrial Relations Observatory (STEREO) twin spacecraft, in combination with the views from the Solar and Heliospheric Observatory (SOHO) and the Solar Dynamics Observatory (SDO), allow us to study the axial and lateral perspectives of a CME simultaneously for the first time. In addition, this study shows that the lateral angular extent ( L) increases linearly with time, while the angular extent of the axial perspective ( D) presents this behavior only from the low corona to {≈} 5 R_{⊙}, where it slows down. The ratio L/D ≈ 1.6 obtained here as the average over several points in time is consistent with measurements of L and D previously performed on events exhibiting only one of the perspectives from the single vantage point provided by SOHO.

California's Garlock Fault, marking the northwestern boundary of the Mojave Desert, lies at the foot of the mountains, running from the lower right to the top center of this image, which was created with data from NASA's shuttle Radar Topography Mission (SRTM), flown in February 2000. The data will be used by geologists studying fault dynamics and landforms resulting from active tectonics. These mountains are the southern end of the Sierra Nevada and the prominent canyon emerging at the lower right is Lone Tree canyon. In the distance, the San Gabriel Mountains cut across from the leftside of the image. At their base lies the San Andreas Fault which meets the Garlock Fault near the left edge at Tejon Pass. The dark linear feature running from lower right to upper left is State Highway 14 leading from the town of Mojave in the distance to Inyokern and the Owens Valley in the north. The lighter parallel lines are dirt roads related to power lines and the Los Angeles Aqueduct which run along the base of the mountains.

This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat satellite image over an SRTM elevation model. Topography is exaggerated 1.5 times vertically. The Landsat image was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota.

Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11,2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast

Integration of a 3D perspective view in the navigation display: featuring pilot's mental model

Synthetic vision systems (SVS) appear as spreading technology in the avionic domain. Several studies prove enhanced situational awareness when using synthetic vision. Since the introduction of synthetic vision a steady change and evolution started concerning the primary flight display (PFD) and the navigation display (ND). The main improvements of the ND comprise the representation of colored ground proximity warning systems (EGPWS), weather radar, and TCAS information. Synthetic vision seems to offer high potential to further enhance cockpit display systems. Especially, concerning the current trend having a 3D perspective view in a SVS-PFD while leaving the navigational content as well as methods of interaction unchanged the question arouses if and how the gap between both displays might evolve to a serious problem. This issue becomes important in relation to the transition and combination of strategic and tactical flight guidance. Hence, pros and cons of 2D and 3D views generally as well as the gap between the egocentric perspective 3D view of the PFD and the exocentric 2D top and side view of the ND will be discussed. Further a concept for the integration of a 3D perspective view, i.e., bird's eye view, in synthetic vision ND will be presented. The combination of 2D and 3D views in the ND enables a better correlation of the ND and the PFD. Additionally, this supports the building of pilot's mental model. The authors believe it will improve the situational and spatial awareness. It might prove to further raise the safety margin when operating in mountainous areas.

Towards a diachronic-synchronic view of future communication policies in Africa.

PubMed

Wilson, D

1989-01-01

Democratic communication policy Africa cannot be exploited by nations that have a technological edge. Traditional, indigenous systems have to be analyzed by a diachronic-synchronic study to establish more effective communication systems for Africa. It is proposed in this diachronic- synchronic view that communication is a cultural transaction and transmission taking place over time. Old processes are synchronized with modern technology resulting in the closure of the cultural gap between traditional and modern societies. Traditional communication processes have been ignored for too long and communication as an industry has become an elite enterprise boasting expensive gadgets (television and radio, newspapers and magazines). Communication is culture, since it is a manifestation of the cultural norms of society. This monopolistic pattern of cultural or media imperialism is pervasive in the Third World. Communication theory is a multidisciplinary field which strongly reflects the music, art, religion, etc. of the society. The communication of religion has become a big cultural activity worldwide, and televangelism is a significant feature of it, although it strictly controlled in Nigeria despite the pervasiveness of religion in society. The traditional communication system consists of the village council of elders and chiefs and the gongman as a broadcaster or reporter. Modern communication systems utilize television, satellite systems, and computers. These powerful instruments, however, have become liabilities in Third World countries. Dominating powers sell these instruments of power and culture to a people who pay for the equipment by foreign loans. A very grave communication problem in Africa is the low literacy rate and the preeminence of foreign languages as the only medium for reaching majority of the literate public. The culture of the poorer nations is often distorted. Exhibition of Africa culture is rare, and Western culture is transmitted to poor nations

Venus - Three-Dimensional Perspective View of Alpha Regio

NASA Technical Reports Server (NTRS)

1992-01-01

A portion of Alpha Regio is displayed in this three-dimensional perspective view of the surface of Venus. Alpha Regio, a topographic upland approximately 1300 kilometers across, is centered on 25 degrees south latitude, 4 degrees east longitude. In 1963, Alpha Regio was the first feature on Venus to be identified from Earth-based radar. The radar-bright area of Alpha Regio is characterized by multiple sets of intersecting trends of structural features such as ridges, troughs, and flat-floored fault valleys that, together, form a polygonal outline. Directly south of the complex ridged terrain is a large ovoid-shaped feature named Eve. The radar-bright spot located centrally within Eve marks the location of the prime meridian of Venus. Magellan synthetic aperture radar data is combined with radar altimetry to develop a three-dimensional map of the surface. Ray tracing is used to generate a perspective view from this map. The vertical scale is exaggerated approximately 23 times. Simulated color and a digital elevation map developed by the U. S. Geological Survey are used to enhance small scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The image was produced at the JPL Multimission Image Processing Laboratory by Eric De Jong, Jeff Hall, and Myche McAuley, and is a single frame from the movie released at the March 5, 1991, press conference.

Perspective View with Landsat Overlay, San Jose, Costa Rica

NASA Technical Reports Server (NTRS)

2002-01-01

This perspective view shows the capital city of San Jose, Costa Rica, the gray area in the center of the image. The view is toward the northwest with the Pacific Ocean in the distance and shows a portion of the Meseta Central (Central Valley), home to about a third of Costa Rica's population.

Like much of Central America, Costa Rica is generally cloud covered, so very little satellite imagery is available. The ability of the Shuttle Radar Topography Mission (SRTM) instrument to penetrate clouds and make three-dimensional measurements will allow generation of the first complete high-resolution topographic map of the entire region. These data were used to generate the image.

This three-dimensional perspective view was generated using elevation data from SRTM and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated two times.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, S.D.

Elevation data used in this image was acquired by the SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000.

Setting research priorities for improving nutrition in Africa is currently ad hoc and there is a need to shift the status quo in the light of slow progress in reducing malnutrition. This study explored African stakeholders' views on research priorities in the context of environmental and socio-demographic changes that will impact on nutritional status in Africa in the coming years. Using Multi-Criteria Mapping, quantitative and qualitative data were gathered from 91 stakeholders representing 6 stakeholder groups (health professionals, food Industry, government, civil society, academics and research funders) in Benin, Mozambique, South Africa, Tanzania, Togo and Uganda. Stakeholders appraised six research options (ecological nutrition, nutritional epidemiology, community nutrition interventions, behavioural nutrition, clinical nutrition and molecular nutrition) for how well they could address malnutrition in Africa. Impact (28.3%), research efficacy (23.6%) and social acceptability (22.4%) were the criteria chosen the most to evaluate the performance of research options. Research on the effectiveness of community interventions was seen as a priority by stakeholders because they were perceived as likely to have an impact relatively quickly, were inexpensive and cost-effective, involved communities and provided direct evidence of what works. Behavioural nutrition research was also highly appraised. Many stakeholders, particularly academics and government were optimistic about the value of ecological nutrition research (the impact of environmental change on nutritional status). Research funders did not share this enthusiasm. Molecular nutrition was least preferred, considered expensive, slow to have an impact and requiring infrastructure. South Africa ranked clinical and molecular nutrition the highest of all countries. Research funders should redirect research funds in Africa towards the priorities identified by giving precedence to develop the evidence for effective

Resolution of public health problems in Africa remains a challenge because of insufficient skilled human resource capacity. The Consortium for Advanced Research Training in Africa (CARTA) was established to enhance capacity in multi-disciplinary health research that will make a positive impact on population health in Africa. The first cohort of the CARTA program describes their perspectives and experiences during the 4 years of fellowship and puts forward suggestions for future progress and direction of research in Africa. The model of training as shown by the CARTA program is an effective model of research capacity building in African academic institutions. An expansion of the program is therefore warranted to reach out to more African academics in search of advanced research training.

The origins of stone tool technology in Africa: a historical perspective

PubMed Central

de la Torre, Ignacio

2011-01-01

The search for the earliest stone tools is a topic that has received much attention in studies on the archaeology of human origins. New evidence could position the oldest traces of stone tool-use before 3.39 Myr, substantially earlier than previously documented. Nonetheless, the first unmistakable evidence of tool-making dates to 2.6 Ma, the period in which Oldowan assemblages first appear in the East African record. However, this is not an unchangeable time boundary, and considerations about the tempo and modo of tool-making emergence have varied through time. This paper summarizes the history of research on the origins of stone knapping in Africa and places the current evidence in a historical perspective. PMID:21357225

The volcanic nature of Mount Shasta is clearly evident in this computer-generated perspective viewed from the northwest. At over 4,300 meters (14,000 feet), Mount Shasta is California's tallest volcano and part of the Cascade chain of volcanoes extending south from Washington. The twin summits of Shasta and Shastina tower over a lava flow on the flank of the volcano. Cutting across the lava flow is the bright line of a railroad. The bright area at the right edge is the town of Weed.

This 3-D perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 5 satellite image. Colors are from Landsat bands 3, 2, and 1 as red, green and blue, respectively. Topographic expression is exaggerated two times.

2014-01-01

Background Accurate assessment of the critical shoulder angle (CSA) is important in clinical evaluation of degenerative rotator cuff tears. This study analyzed the influence of radiographic viewing perspective on the CSA, developed a classification system to identify malpositioned radiographs, and assessed the relationship between the CSA and demographic factors. Methods Glenoid height, width and retroversion were measured on 3D CT reconstructions of 68 cadaver scapulae. A digitally reconstructed radiograph was aligned perpendicular to the scapular plane, and retroversion was corrected to obtain a true antero-posterior (AP) view. In 10 scapulae, incremental anteversion/retroversion and flexion/extension views were generated. The CSA was measured and a clinically applicable classification system was developed to detect views with >2° change in CSA versus true AP. Results The average CSA was 33±4°. Intra- and inter-observer reliability was high (ICC≥0.81) but decreased with increasing viewing angle. Views beyond 5° anteversion, 8° retroversion, 15° flexion and 26° extension resulted in >2° deviation of the CSA compared to true AP. The classification system was capable of detecting aberrant viewing perspectives with sensitivity of 95% and specificity of 53%. Correlations between glenoid size and CSA were small (R≤0.3), and CSA did not vary by gender (p=0.426) or side (p=0.821). Conclusions The CSA was most susceptible to malposition in ante/retroversion. Deviations as little as 5° in anteversion resulted in a CSA >2° from true AP. A new classification system refines the ability to collect true AP radiographs of the scapula. The CSA was unaffected by demographic factors. PMID:25591458

Perspective View with Color-Coded Shaded Relief, Central Panama

NASA Technical Reports Server (NTRS)

2002-01-01

This perspective view shows central Panama, with the remnants of the extinct volcano El Valle in the foreground and the Caribbean Sea in the distance. El Valle underwent an explosive eruption about 3 million years ago, forming a crater 5 kilometers (3.1 miles) across, one of the largest in the Americas. The crater subsequently filled with water forming a huge lake, but about 12,000 years ago a breach at the present site of the waterfall Choro de las Mozas caused it to drain, forming the present valley. Within the crater is the town of El Valle de Anton, whose 600-meter (1,968-foot) elevation and resulting cooler climate make it a popular tourist and vacation site.

The lake in the distance is Lake Gatun, at the west end of the Panama Canal. The canal itself extends to the southwest (to the right in this northeast facing view) but is hidden by the intervening terrain.

This shaded relief perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM). A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. Colors show the elevation as measured by SRTM, and range from green at the lowest elevations to white at the highest elevations.

2001-01-01

Santa Barbara, California, is often called 'America's Riviera.' It enjoys a Mediterranean climate, a mountain backdrop, and a long and varied coastline. This perspective view of the Santa Barbara region was generated using data from the Shuttle Radar Topography Mission (SRTM) and an enhanced Landsat satellite image. The view is toward the northeast, from the Goleta Valley in the foreground to a snow-capped Mount Abel (elevation 2526 m or 8286 feet) along the skyline. The coast here generally faces south. Consequently, Fall and Winter sunrises occur over the ocean, which is unusual for the U.S. west coast. The Santa Barbara 'back country' is very rugged and largely remains as undeveloped wilderness and an important watershed for local communities. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data match the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. For visualization purposes, topographic heights displayed in this image are exaggerated two times. Colors approximate natural colors.

The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of Earth's land surface.

To collect the 3-D SRTM data, engineers added a mast 60 meters (about 200-feet) long, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense, and the German and Italian space agencies.

This perspective view shows the Panama Canal with the Gulf of Panama in the foreground and the Caribbean Sea in the distance. The canal runs northwest-southeast from the city of Colon on the Atlantic side to Panama City on the Pacific side. Water levels are maintained along its length by three reservoirs, the largest of which is Lake Gatun, visible at the right center of the image. Built by the U.S. Army Corps of Engineers between 1904 and 1914, the canal extends for approximately 50 miles, and is widely considered to be one of the world's great engineering achievements.

This shaded relief perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM).

Migration in southern Africa: a comparative perspective.

PubMed

Solomon, H

1994-01-01

Population movement can be described as intra-state, East-West, South-North, and South-South. About 20 million persons globally are considered displaced, of which about 4.1 million are internally displaced persons in South Africa. East-West movement occurred for over 400 million when the Iron Curtain came down. South-North movements of asylum seekers were estimated at 442,000 in 1990. South-South movement amounted to 4 million official refugees in Africa in 1989 and 4.4 million in 1990. African has the largest concentration of refugees. This article does not address the 265,825 contract migrant workers in South Africa. South African migration is the South-South type and can be characterized as "brain-drain" of well-trained professionals in neighboring states and unskilled and illegal migrants from Mozambique and Angola. Movement is pushed or pulled according to sociocultural factors, communications and technology, geographic proximity, precedent, demographic factors, environmental factors, economic factors, and political factors. The effects of migration in South Africa include increased stress on housing, political and social tension, increased costs, overcrowding, transmission of disease, and marginalization of migrants into low status and low paid jobs. For Lesotho migrants in South Africa remittances are a major source of national wealth. South Africa has also experienced racial discord against Mozambicans and Chinese. Political right wing groups mobilize around anti-immigration platforms. Migrants can become policy tools, and many are used in wars of liberation. International attention may focus on mistreatment of refugees. Management can be construed as "carrot" or "stick" approaches. Stick approaches include forced repatriation, limiting immigration, housing in survival-level camps, public campaigns run by host countries in sending countries, or greater control of national borders. South Africa has extensively used stick approaches, which have been only

This is a three dimensional perspective view of Isla Isabela in the western Galapagos Islands. It was taken by the L-band radar in HH polarization from the Spaceborne Imaging Radar-C/X-Band Synthetic Aperature Radar on the 40th orbit of the Shuttle Endeavour. This view was constructed by overlaying a SIR-C radar image on a U.S. Geological Survey digital elevation map. The image is centered at about .5 degrees south latitude and 91 degrees West longitude and covers an area of 75 km by 60 km. This SIR-C/X-SAR image of Alcedo and Sierra Negra volcanoes shows the rougher lava flows as bright features, while ash deposits and smooth Pahoehoe lava flows dark. The Jet Propulsion Laboratory alternative photo number is P-43938.

Mental health service utilization in sub-Saharan Africa: is public mental health literacy the problem? Setting the perspectives right.

PubMed

Atilola, Olayinka

2016-06-01

The severely constrained resources for mental health service in less-developed regions like sub-Saharan Africa underscore the need for good public mental health literacy as a potential additional mental health resource. Several studies examining the level of public knowledge about the nature and dynamics of mental illness in sub-Saharan Africa in the last decade had concluded that such knowledge was poor and had called for further public enlightenment. What was thought to be mental health 'ignorance' has also been blamed for poor mainstream service utilization. These views however assume that non-alignment of the views of community dwellers in sub-Saharan Africa with the biomedical understanding of mental illness connotes 'ignorance', and that correcting such 'ignorance' will translate to improvements in service utilization. Within the framework of contemporary thinking in mental health literacy, this paper argues that such assumptions are not culturally nuanced and may have overrated the usefulness of de-contextualized public engagement in enhancing mental health service utilization in the region. The paper concludes with a discourse on how to contextualize public mental health enlightenment in the region and the wider policy initiatives that can improve mental health service utilization. © The Author(s) 2015.

Perspective View with Landsat Overlay, Lakes Managua and Nicaragua

NASA Technical Reports Server (NTRS)

2002-01-01

This perspective view shows Lakes Managua and Nicaragua near the Pacific coast of Nicaragua. Lake Managua is the 65-kilometer (40-mile)-long fresh water lake in the foreground of this south-looking view, emptying via the Tipitapa River into the much larger Lake Nicaragua in the distance. The capital city of Managua, with a population of more than 500,000, is located along the southern shore of Lake Managua, the area with the highest population density in Nicaragua.

The physical setting of Lake Managua is dominated by the numerous volcanic features aligned in a northwest-southeast axis. The cone-like feature in the foreground is Momotombo, a 1,280-meter (4,199-foot)-high stratovolcano located on the northwest end of the lake. Two water-filled volcanic craters (Apoyegue and Jiloa volcanoes) reside on the Chiltepe Peninsula protruding into the lake from the west. Two volcanoes can also be seen on the island of Ometepe in Lake Nicaragua: El Maderas rising to 1,394 meters (4,573 feet) and the active El Conception at 1,610 meters (5,282 feet).

This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated two times.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, S.D.

Elevation data used in this image was acquired by the SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne

Perspective View, Mt. Etna, Italy & the Aeolian Islands

2002-11-01

Italy's Mount Etna and the Aeolian Islands are the focus of this perspective view made from an Advanced Spaceborne Thermal and Emission Radiometer (ASTER) image from NASA's Terra spacecraft overlaid on Shuttle Radar Topography Mission (SRTM) topography. The image is looking south with the islands of Lipari and Vulcano in the foreground and Etna with its dark lava flows on the skyline. Vulcano also hosts an active volcano, the cone of which is prominent. In late October 2002, Etna erupted again, sending lava flows down the north and south sides of the volcano. The north flows are near the center of this view, but the ASTER image is from before the eruption. In addition to the terrestrial applications of these data for understanding active volcanoes and hazards associated with them such as lava flows and explosive eruptions, geologists studying Mars find these data useful as an analog to martian landforms and geologic processes. In late September 2002, a field conference with the theme of Terrestrial Analogs to Mars focused on Mount Etna allowing Mars geologists to see in person the types of features they can only sample remotely. http://photojournal.jpl.nasa.gov/catalog/PIA03370

Towards a gender perspective in qualitative research on voluntary medical male circumcision in east and southern Africa.

PubMed

Martínez Pérez, Guillermo; Triviño Durán, Laura; Gasch, Angel; Desmond, Nicole

2015-01-01

The World Health Organization endorsed voluntary medical male circumcision (VMMC) in 2007 as an effective method to provide partial protection against heterosexual female-to-male transmission of HIV in regions with high rates of such transmission, and where uptake of VMMC is low. Qualitative research conducted in east and southern Africa has focused on assessing acceptability, barriers to uptake of VMMC and the likelihood of VMMC increasing men's adoption of risky sexual behaviours. Less researched, however, have been the perceptions of women and sexual minorities towards VMMC, even though they are more vulnerable to HIV/AIDS transmission than are heterosexual men. The purpose of this paper is to identify core areas in which a gendered perspective in qualitative research might improve the understanding and framing of VMMC in east and southern Africa. Issues explored in this analysis are risk compensation, the post-circumcision appearance of the penis, inclusion of men who have sex with men as study respondents and the antagonistic relation between VMMC and female genital cutting. If biomedical and social science researchers explore these issues in future qualitative inquiry utilising a gendered perspective, a more thorough understanding of VMMC can be achieved, which could ultimately inform policy and implementation.

Salt Lake City, Utah, Perspective View

NASA Technical Reports Server (NTRS)

2001-01-01

The 2002 Winter Olympics are hosted by Salt Lake City at several venues within the city, in nearby cities, and within the adjacent Wasatch Mountains. This 3-D perspective view, in simulated natural colors, presents a late spring view over Salt Lake City towards the snow-capped Wasatch Mountains to the east. The image was created by draping ASTER image data over digital topography data from the US Geological Survey's National Elevation Data.

This image was acquired on May 28, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet.

ASTER is one of five Earth-observing instruments launched December 18,1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. Science team leader; Bjorn Eng of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The Terra mission is part of NASA's Earth Science Enterprise, a long-term research and technology program designed to examine Earth's land, oceans, atmosphere, ice and life as a total integrated system.

The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation

Contagious bovine pleuropneumonia (CBPP) is a disease of economic importance that is widely distributed in sub-Saharan African and contributes significantly to cattle morbidity and mortality. Control of CBPP offers a number of challenges as a result many developing countries in Africa are still struggling with this disease. In this study, we look at the challenges encountered in CBPP control in sub-Saharan Africa from the Zambian perspective. In conducting this study, we reviewed scientific literature and reports from the Ministry of Agriculture and Livestock and related animal institutions, and also made interviews with experts and key government officials involved in CBPP control in Zambia. Among the challenges identified for the successful control of CBPP were as follows: failure in the delivery of veterinary services, lack of a cattle identification system, natural phenomenon, livestock husbandry systems in the traditional sector, human movements, traditional practices among cattle farmers and cattle marketing systems. It was seen that the epidemiology of CBPP in Zambia is influenced by both ecological and anthological factors. Therefore, design and implementation of any control or eradication programme should be area/regional-dependent taking into account the different factors influencing disease transmission and maintenance.

Lightning over Equatorial Africa

These two images were taken 9 seconds apart as the STS-97 Space Shuttle flew over equatorial Africa east of Lake Volta on December 11, 2000. The top of the large thunderstorm, roughly 20 km across, is illuminated by a full moon and frequent bursts of lightning. Because the Space Shuttle travels at about 7 km/sec, the astronaut perspectives on this storm system becomes more oblique over the 9-second interval between photographs. The images were taken with a Nikon 35 mm camera equipped with a 400 mm lens and high-speed (800 ISO) color negative film. Images are STS097-351-9 and STS097-351-12, provided and archived by the Earth Science and Image Analysis Laboratory, Johnson Space Center.

Perspective View of Shaded Relief with Color as Height, Miyake-Jima, Japan

NASA Technical Reports Server (NTRS)

2000-01-01

This 3D perspective view shows the Japanese island called Miyake-Jima viewed from the northeast. This island -- about 180 kilometers (110 miles) south of Tokyo -- is part of the Izu chain of volcanic islands that runs south from the main Japanese island of Honshu. Dominated by the 820-meter-high (2,700 feet) volcano Mount Oyama, Miyake-Jima is home to 3,800 people. In late June 2000, a series of earthquakes alerted scientists to possible volcanic activity and on June 27 authorities evacuated 2,600 people. On July 7, the island was hit by a typhoon passing overhead, and on July 8 the volcano began erupting. The volcano erupted five times over the next week, spreading gray ash over surrounding areas. Detailed topographic information can be used to predict the directions that lava flows will take. The previous major eruption of Mount Oyama occurred in 1983, when lava flows destroyed hundreds of houses, and an earlier eruption in 1940 killed 11 people.

This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows, while colors show the elevation as measured by SRTM. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. The elevation is indicated by colors. Lowest elevation areas appear blue, medium elevations appear green, while higher elevations appear brown and white.

The Shuttle Radar Topography Mission (SRTM), launched on February 11, 2000, used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994.

Perspective view, Landsat overlay Oahu, Hawaii

NASA Technical Reports Server (NTRS)

2000-01-01

Honolulu, on the island of Oahu, is a large and growing urban area with limited space and water resources. This perspective view, combining a Landsat image with SRTM topography, shows how the topography controls the urban growth pattern, causes cloud formation, and directs the rainfall runoff pattern. Features of interest in this scene include downtown Honolulu (right), Honolulu Harbor (right), Pearl Harbor (center), and offshore reef patterns (foreground). The Koolau mountain range runs through the center of the image. On the north shore of the island are the Mokapu Peninsula and Kaneohe Bay (upper right). Clouds commonly hang above ridges and peaks of the Hawaiian Islands, and in this rendition appear draped directly on the mountains. The clouds are actually about 1000 meters (3300 feet) above sea level. High resolution topographic and image data allow ecologists and planners to assess the effects of urban development on the sensitive ecosystems in tropical regions.

This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat 7 satellite image over an SRTM elevation model. Topography is exaggerated about six times vertically. The Landsat 7 image was acquired on February 12, 2000, and was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS)Data Center, Sioux Falls, South Dakota.

Background South Africa faces a complex burden of disease consisting of infectious and non–communicable conditions, injury and interpersonal violence, and maternal and child mortality. Inequalities in income and opportunity push disease burdens towards vulnerable populations, a situation to which the health system struggles to respond. There is an urgent need for health planning to account for the needs of marginalized groups in this context. The study objectives were to develop a process to elicit the perspectives of local communities in the established Agincourt health and socio-demographic surveillance site (HDSS) in rural north–east South Africa on two leading causes of death: HIV/AIDS and violent assault, and on health surveillance as a means to generate information on health in the locality. Methods Drawing on community–based participatory research (CBPR) methods, three village–based groups of eight participants were convened, with whom a series of discussions were held to identify and define the causes of, treatments for, and problems surrounding, deaths due to HIV/AIDS and violent assault. The surveillance system was also discussed and recommendations generated. The discussion narratives were the main data source, examined using framework analysis. Results The groups identified a range of social and health systems issues including risky sexual health behaviors, entrenched traditional practices, alcohol and substance abuse, unstable relationships, and debt as causative. Participants also explained how compromised patient confidentiality in clinics, insensitive staff, and a biased judicial system were problematic for the treatment and reporting of both conditions. Views on health surveillance were positive. Recommendations to strengthen an already well–functioning system related to maintaining confidentiality and sensitivity, and extending ancillary care obligations. Conclusion The discussions provided information not available from other sources on

Towards the implementation of malaria elimination policy in South Africa: the stakeholders' perspectives.

2017-01-01

The past decade has seen substantial global reduction in malaria morbidity and mortality due to increased international funding and decisive steps by the international malaria community to fight malaria. South Africa has been declared ready to institute malaria elimination. However, research on the factors that would affect this policy implementation is inadequate. To investigate the stakeholders' understanding of the malaria elimination policy in South Africa, including their perceived barriers and facilitators to effective policy implementation. The study followed a constructivist epistemological approach which manifests in phenomenological study design. Twelve purposively selected key informants from malaria researchers, provincial and national malaria programmes were interviewed using semi-structured interviews. Interview questions elicited interviewees' knowledge of the policy and its achievability, including any perceived barriers and facilitating factors to effective implementation. The hybrid approach was used to perform thematic data analysis. The dominant view was that malaria remains a problem in South Africa, exacerbated by staff attitudes and poor capacity, lack of resources, lack of new effective intervention tools, lack of intra- and inter-departmental collaboration, poor cross-border collaboration and weak stakeholder collaboration. Informants were concerned about the target year (2018) for elimination, and about the process followed in developing the policy, including the perceived malaria epidemiology shortfalls, regulatory issues and political context of the policy. Achievability of malaria elimination remains a subject of intense debate for a variety of reasons. These include the sporadic nature of malaria resurgence, raising questions about the contributions of malaria control interventions and climate to the transmission trends in South Africa. The shortage of resources, inadequate staff capacity, lack of any new effective intervention tools

Method for producing three-dimensional real image using radiographic perspective views of an object

DOEpatents

Ellingson, William A.; Read, Alvin A.

1976-02-24

A sequence of separate radiographs are made by indexing a radiation source along a known path relative to the object under study. Thus, each radiograph contains information from a different perspective. A holographically-recorded image is then made from each radiographic perspective by exact re-tracing of the rays through each radiographic perspective such that the re-tracing duplicates the geometry under which it was originally prepared. The holographically-stored images are simultaneously illuminated with the conjugate of the reference beam used in the original recordings. The result is the generation of a three-dimensional real image of the object such that a light-sensitive device can be moved to view the real image along any desired surface with the optical information in all other surfaces greatly suppressed.

Taste at first (person) sight: Visual perspective modulates brain activity implicitly associated with viewing unhealthy but not healthy foods.

Every day, people are exposed to images of appetizing foods that can lead to high-calorie intake and contribute to overweight and obesity. Research has documented that manipulating the visual perspective from which eating is viewed helps resist temptation by altering the appraisal of unhealthy foods. However, the neural basis of this effect has not yet been examined using neuroimaging methods. Moreover, it is not known whether the benefits of this strategy can be observed when people, especially overweight, are not explicitly asked to imagine themselves eating. Last, it remains to be investigated if visual perspective could be used to promote healthy foods. The present work manipulated camera angles and tested whether visual perspective modulates activity in brain regions associated with taste and reward processing while participants watch videos featuring a hand grasping (unhealthy or healthy) foods from a plate during functional magnetic resonance imagining (fMRI). The plate was filmed from the perspective of the participant (first-person perspective; 1PP), or from a frontal view as if watching someone else eating (third-person perspective; 3PP). Our findings reveal that merely viewing unhealthy food cues from a 1PP (vs. 3PP) increases activity in brain regions that underlie representations of rewarding (appetitive) experiences (amygdala) and food intake (superior parietal gyrus). Additionally, our results show that ventral striatal activity is positively correlated with body mass index (BMI) during exposure to unhealthy foods from a 1PP (vs. 3PP). These findings suggest that unhealthy foods should be promoted through third-person (video) images to weaken the reward associated with their simulated consumption, especially amongst overweight people. It appears however that, as such, manipulating visual perspective fails to enhance the perception of healthy foods. Their promotion thus requires complementary solutions. Copyright © 2018.

Anaglyph of Perspective View with Aerial Photo Overlay Pasadena, California

NASA Technical Reports Server (NTRS)

2000-01-01

This anaglyph is a perspective view that shows the western part of the city of Pasadena, California, looking north toward the San Gabriel Mountains. Red-blue glasses are required to see the 3-D effect. Portions of the cities of Altadena and La Canada-Flintridge are also shown. The image was created from two datasets: the Shuttle Radar Topography Mission (SRTM) supplied the elevation data and U. S. Geological Survey digital aerial photography provided the image detail. The Jet Propulsion Laboratory is the cluster of large buildings left of center, at the base of the mountains. This image shows the power of combining data from different sources to create planning tools to study problems that affect large urban areas. In addition to the well-known earthquake hazards, Southern California is affected by a natural cycle of fire and mudflows. Wildfires can strip the mountains of vegetation, increasing the hazards from flooding and mudflows. Data shown in this image can be used to predict both how wildfires spread over the terrain and how mudflows are channeled down the canyons.

This anaglyph was generated using topographic data from the Shuttle Radar Topography Mission to create two differing perspectives of a single image, one perspective for each eye. Each point in the image is shifted slightly, depending on its elevation. When viewed through special glasses, the result is a view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter.

The World Health Organisation has advocated for comprehensive primary care teams, which include family physicians. However, despite (or because of) severe doctor shortages in Africa, there is insufficient clarity on the role of the family physician in the primary health care team. Instead there is a trend towards task shifting without thought for teamwork, which runs the risk of dangerous oversimplification. It is not clear how African leaders understand the challenges of implementing family medicine, especially in human resource terms. This study, therefore, sought to explore the views of academic and government leaders on critical human resource issues for implementation of family medicine in Africa. In this qualitative study, key academic and government leaders were purposively selected from sixteen African countries. In-depth interviews were conducted using an interview guide. All interviews were audio-recorded, transcribed and thematically analysed. There were 27 interviews conducted with 16 government and 11 academic leaders in nine Sub-Saharan African countries: Botswana, Democratic Republic of Congo, Ghana, Kenya, Malawi, Nigeria, Rwanda, South Africa and Uganda. Respondents spoke about: educating doctors in family medicine suited to Africa, including procedural skills and holistic care, to address the difficulty of recruiting and retaining doctors in rural and underserved areas; planning for primary health care teams, including family physicians; new supervisory models in primary health care; and general human resource management issues. Important milestones in African health care fail to specifically address the human resource issues of integrated primary health care teamwork that includes family physicians. Leaders interviewed in this study, however, proposed organising the district health system with a strong embrace of family medicine in Africa, especially with regard to providing clinical leadership in team-based primary health care.

The 2002 Winter Olympics are hosted by Salt Lake City at several venues within the city, in nearby cities, and within the adjacent Wasatch Mountains. This computer generated perspective image provides a northward looking 'view from space' that includes all of these Olympic sites. In the south, next to Utah Lake, Provo hosts the ice hockey competition. In the north, northeast of the Great Salt Lake, Ogden hosts curling, and the nearby Snow Basin ski area hosts the downhill events. In between, southeast of the Great Salt Lake, Salt Lake City hosts the Olympic Village and the various skating events. Further east, across the Wasatch Mountains, the Park City area ski resorts host the bobsled, ski jumping, and snowboarding events. The Winter Olympics are always hosted in mountainous terrain. This view shows the dramatic landscape that makes the Salt Lake City region a world-class center for winter sports.

This image of the Santa Barbara, California, region provides a beautiful snapshot of the area's rugged mountains and long and varied coastline. Generated using data acquired from the Shuttle Radar Topography Mission (SRTM) and an enhanced Landsat image this is a perspective view toward the northeast, from the Goleta Valley in the foreground to a snow-capped Mount Abel (elevation 2,526 m or 8,286 feet) along the skyline at the left. On a clear day, a pilot might see a similar view shortly before touching down on the east-west runway of the Santa Barbara Airport, seen just to the left of the coastline near the center of image. This area is one of the few places along the U.S. West Coast where because of a south-facing beach, fall and winter sunrises occur over the ocean.

As the second of 3 articles in this series, the aim of this article is to provide readers with an understanding of the development of neurosurgery in East Africa (foundations), the challenges that arise in providing neurosurgical care in developing countries (challenges), and an overview of traditional and novel approaches to overcoming these challenges and improving health care in the region (innovations). Recognizing the challenges that need to be addressed is the first step to implementing efficient and qualified surgery delivery systems in low- and middle-income countries. We reviewed the major challenges facing health care in East Africa and grouped them into 5 categories: 1) burden of surgical disease and workforce crisis; 2) global health view of surgery as "the neglected stepchild"; 3) need for recognizing the surgical system as an interdependent network and importance of organizational and equipment deficits; 4) lack of education in the community, failure of primary care systems, and net result of overwhelming tertiary care systems; 5) personal and professional burnout as well as brain drain of promising human resources from low- and middle-income countries in East Africa and similar regions across the world. Each major challenge was detailed and analyzed by authors who have worked or are currently working in the region, providing a personal perspective. Copyright © 2018. Published by Elsevier Inc.

Perspective view, Landsat overlay San Andreas Fault, Palmdale, California

NASA Technical Reports Server (NTRS)

2000-01-01

The prominent linear feature straight down the center of this perspective view is the San Andreas Fault. This segment of the fault lies near the city of Palmdale, California (the flat area in the right half of the image) about 60 kilometers (37 miles) north of Los Angeles. The fault is the active tectonic boundary between the North American plate on the right, and the Pacific plate on the left. Relative to each other, the Pacific plate is moving away from the viewer and the North American plate is moving toward the viewer along what geologists call a right lateral strike-slip fault. Two large mountain ranges are visible, the San Gabriel Mountains on the left and the Tehachapi Mountains in the upper right. The Lake Palmdale Reservoir, approximately 1.5 kilometers (0.9 miles) across, sits in the topographic depression created by past movement along the fault. Highway 14 is the prominent linear feature starting at the lower left edge of the image and continuing along the far side of the reservoir. The patterns of residential and agricultural development around Palmdale are seen in the Landsat imagery in the right half of the image. SRTM topographic data will be used by geologists studying fault dynamics and landforms resulting from active tectonics.

This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat satellite image over an SRTM elevation model. Topography is exaggerated 1.5 times vertically. The Landsat image was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota.

2015-06-12

Human immunodeficiency virus clinical trials are increasingly being conducted in sub-Saharan Africa. There is a tension between the pressure to increase levels of research participation and the need to ensure informed consent and protection of participants' rights. Researchers need to be aware of the particular ethical issues that underpin Human immunodeficiency virus research conduct in low income settings. This necessitates hearing from those who have participated in research and who have direct experience of the research process. This review aimed to synthesize and present the best available evidence in relation to Human immunodeficiency virus research participation in sub-Saharan Africa, based on the views and experiences of research participants. The review included studies whose participants were current or former adult Human immunodeficiency virus research participants from sub-Saharan African countries. Views, experiences, attitudes, understandings, perceptions and perspectives of Human immunodeficiency virus research participants in sub-Saharan Africa. Types of studies: This review considered studies that focused on qualitative data, including, but not limited to, designs such as phenomenology, ethnography, grounded theory, action research and feminist research. A three-step search strategy was utilized. Seven databases (CINAHL, Ovid MEDLINE (R) 1946, ASSIA, PsychInfo, Web of Science, EMBASE, and African Index Medicus) were searched with no limitation to years of publication, followed by hand searching of reference lists. Only studies published in the English language were considered. Methodological quality was assessed using the Qualitative Assessment and Review Instrument developed by the Joanna Briggs Institute. Qualitative findings were extracted using the Joanna Briggs Institute Qualitative Assessment and Review Instrument.

Hebbar, Prakash K

ABSTRACT Diseases of cacao, Theobroma cacao, account for losses of more than 30% of the potential crop. These losses have caused a steady decline in production and a reduction in bean quality in almost all the cacao-producing areas in the world, especially in small-holder farms in Latin America and West Africa. The most significant diseases are witches' broom, caused by Moniliophthora perniciosa, which occurs mainly in South America; frosty pod rot, caused by M. roreri, which occurs mainly in Central and northern South America; and black pod disease, caused by several species of Phytophthora, which are distributed throughout the tropics. In view of the threat that these diseases pose to the sustainability of the cacao crop, Mars Inc. and their industry partners have funded collaborative research involving cacao research institutes and governmental and nongovernmental agencies. The objective of this global initiative is to develop short- to medium-term, low-cost, environmentally friendly disease-management strategies until disease tolerant varieties are widely available. These include good farming practices, biological control and the rational or minimal use of chemicals that could be used for integrated pest management (IPM). Farmer field schools are used to get these technologies to growers. This paper describes some of the key collaborative partners and projects that are underway in South America and West Africa.

This perspective view shows the capital city of San Jose, Costa Rica, in the right center of the image (gray area). Rising behind it are the volcanoes Irazu, 3402 meters high (11,161 feet) and Turrialba, 3330 meters high (10,925 feet.)

Irazu is the highest volcano in Costa Rica and is located in the Irazu Volcano National Park, established in 1955. There have been at least 23 eruptions of Irazu since 1723, the most recent during 1963 to 1965. This activity sent tephra and secondary mudflows into cultivated areas, caused at least 40 deaths, and destroyed 400 houses and some factories.

This image was generated in support of the Central American Commission for Environment and Development through an agreement with NASA. The Commission involves eight nations working to develop the Mesoamerican Biological Corridor, an effort to study and preserve some of the most biologically diverse regions of the planet.

An interest exists in understanding why adolescents partake in risky sexual behaviours, as well as the risk and protective practices associated with risky sexual behaviour. The aim of this study was to investigate the moderator effect of future time perspective in the relationship between self-efficacy and risky sexual behaviour. A random cluster consisting of 467 learners from English medium high schools of central South Africa participated in this study. The participants' risky sexual behaviour, self-efficacy and future time perspective were measured with the Perceptions of HIV/AIDS Risk Survey, Generalised Perceived Self-efficacy Scale and the Zimbardo Time Perspective Inventory, respectively. Product term regression analysis was performed. It was found that both self-efficacy and future time perspective were negatively related to risky sexual behaviour. No moderating effect was found for future time perspective in the relationship between self-efficacy and risky sexual behaviour. Self-efficacy and future time perspective were identified as qualities that protect adolescents from engaging in risky sexual behaviours. This finding can be useful in developing prevention programmes. Intervention programmes aimed at the youth should foster a sense of hope and possibility about the future and the development of goals and aspirations to prevent risky behaviour.

Venus - 3D Perspective View of Eastern Edge of Alpha Regio

NASA Technical Reports Server (NTRS)

1991-01-01

A portion of the eastern edge of Alpha Regio is displayed in this three-dimensional perspective view of the surface of Venus. The viewpoint is located at approximately 30 degrees south latitude, 11.8 degrees east longitude at an elevation of 2.4 kilometers (3.8 miles). The view is to the northeast at the center of an area containing seven circular dome-like hills. The average diameter of the hills is 25 kilometers (15 miles) with maximum heights of 750 meters (2,475 feet). Three of the hills are visible in the center of the image. Fractures on the surrounding plains are both older and younger than the domes. The hills may be the result of viscous or thick eruptions of lava coming from a vent on the relatively level ground, allowing the lava to flow in an even lateral pattern. The concentric and radial fracture patterns on their surfaces suggests that a chilled outer layer formed, then further intrusion in the interior stretched the surface. An alternative interpretation is that domes are the result of shallow intrusions of molten lava, causing the surface to rise. If they are intrusive, then magma withdrawal near the end of the eruptions produced the fractures. The bright margins possibly indicate the presence of rock debris or talus at the slopes of the domes. Resolution of the Magellan data is about 120 meters (400 feet). Magellan's synthetic aperture radar is combined with radar altimetry to develop a three-dimensional map of the surface. A perspective view is then generated from the map. Simulated color and a process called radar-clinometry are used to enhance small-scale structures. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The image was produced by the JPL Multimission Image Processing Laboratory by Eric De Jong, Jeff Hall, Myche McAuley, and Randy Kirk of the United States Geological Survey, and is a single frame from the movie released at the May 29, 1991 Magellan news conference.

2001-01-01

This simulated true color perspective view over the Grand Canyon was created from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data acquired on May 12, 2000. The Grand Canyon Village is in the lower foreground; the Bright Angel Trail crosses the Tonto Platform, before dropping down to the Colorado Village and then to the Phantom Ranch (green area across the river). Bright Angel Canyon and the North Rim dominate the view. At the top center of the image the dark blue area with light blue haze is an active forest fire.

ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate.

The concurrent use of traditional African medicine (TAM) and allopathic medicine is not well understood for people living with HIV (PLHIV) in the era of antiretroviral therapy (ART). This cross-sectional, qualitative study examines perceptions of the concurrent use of TAM and ART among: i) patients receiving ART at the Sinikithemba HIV Clinic of McCord Hospital, in Durban, South Africa; ii) allopathic medical providers (doctors, nurses, HIV counsellors) from Sinikithemba; and iii) local traditional healers. Data were collected through in-depth interviews and focus group discussions with 26 participants between July and October, 2011. Patients in this study did not view TAM as an alternative to ART; rather, results show that patients employ TAM and ART for distinctly different needs. More research is needed to further understand the relationship between traditional and allopathic approaches to health care in South Africa, to improve cultural relevance in the provision and delivery of care for PLHIV, and to pragmatically address the concerns of healthcare providers and public health officials managing this intersection in South Africa and elsewhere.

A Perspective on Invasive Salmonella Disease in Africa.

PubMed

Crump, John A; Heyderman, Robert S

2015-11-01

Salmonella enterica is a leading cause of community-acquired bloodstream infection in Africa. The contribution of typhoidal and nontyphoidal Salmonella serovars to invasive disease varies considerably in place and time, even within the same country. Nonetheless, many African countries are now thought to experience typhoid fever incidence >100 per 100,000 per year with approximately 1% of patients dying. Invasive nontyphoidal Salmonella (iNTS) disease was estimated to cause 3.4 million illnesses and 681 316 deaths in 2010, with the most disease in Africa. Antimicrobial drug resistance is a growing problem in S. enterica that threatens to further compromise patient outcomes. Reservoirs for nontyphoidal Salmonella and the predominant routes of transmission for typhoidal and nontyphoidal Salmonella are not well understood in Africa, hampering the design of evidence-based, non-vaccine- and vaccine-based prevention measures. It is difficult to distinguish clinically invasive Salmonella disease from febrile illnesses caused by other pathogens. Blood cultures are the mainstay of laboratory diagnosis, but lack sensitivity due to the low magnitude of bacteremia, do not produce results at point of care, and are not widely available in Africa. Serologic approaches to diagnosis remain inaccurate, and nucleic acid amplification tests are also compromised by low concentrations of bacteria. High-throughput whole-genome sequencing, together with a range of novel analytic pipelines, has provided new insights into the complex pattern of epidemiology, pathogenesis, and host adaptation. Concerted efforts are therefore needed to apply these new tools in the context of high-quality field surveillance to improve diagnosis, patient management, control, and prevention of invasive Salmonella infections in Africa. © The Author 2015.

Pwyll Impact Crater: Perspective View of Topographic Model

NASA Technical Reports Server (NTRS)

1998-01-01

This computer-generated perspective view of the Pwyll impact crater on Jupiter's moon Europa was created using images taken by NASA's Galileo spacecraft camera when the spacecraft flew past that moon on Feb. 20 and Dec. 16, 1997 during its 6th and 12th orbits of Jupiter. Images of the crater taken from different angles on the different orbits have been combined to generate a model of the topography of Pwyll and its surroundings. This simulated view is from the southwest at a 45 degree angle, with the vertical exaggerated four times the natural size. The colors represent different elevation levels with blue being the lowest and red the highest. Pwyll, about 26 kilometers (16 miles) across, is unusual among craters in the solar system, because its floor is at about the same elevation as the surrounding terrain. Moreover, its central peak, standing approximately 600 meters (almost 2,000 feet) above the floor, is much higher than its rim. This may indicate that the crater was modified shortly after its formation by the flow of underlying warm ice.

The understanding of the genetic basis of neurological disorders has grown rapidly in the last two decades. Despite the genomic heterogeneity within African populations, large-scale candidate gene or linkage and exome studies are lacking. However, current knowledge on neurogenetics in African populations is limited and geographically very uneven. Isolated reports indicate the existence of autosomal dominant or recessive conditions incorporating cerebrovascular, movement, neuromuscular, seizure and motor neuron disorders in Africans. In addition, few African families with neurodegenerative disorders associated with dementia have been characterized in North, West and South Africa. The current insurgency in genomic research triggered by among others the Human Health and Heredity (H3) Africa Initiative indicates that there are unique opportunities to advance our knowledge and understanding of the influence of genomic variation on the pattern, presentations and prognosis of neurological disorders in Africa. These have enormous potential to unmask novel genes and molecular pathways germane to the neurobiology of brain disorders. It would facilitate the development of novel diagnostics, preventative and targeted treatments in the new paradigm of precision medicine. Nevertheless, it is crucial to strike a balance between effective traditional public health strategies and personalized genome based care. The translational barriers can be overcome through robust stakeholder engagement and sustainable multilevel, multigenerational and multidisciplinary capacity building and infrastructural development for genomic medicine in Africa.

2004-01-01

Portland, the largest city in Oregon, is located on the Columbia River at the northern end of the Willamette Valley. On clear days, Mount Hood highlights the Cascade Mountains backdrop to the east. The Columbia is the largest river in the American Northwest and is navigable up to and well beyond Portland. It is also the only river to fully cross the Cascade Range, and has carved the Columbia River Gorge, which is seen in the left-central part of this view. A series of dams along the river, at topographically favorable sites, provide substantial hydroelectric power to the region.

This perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM), a Landsat satellite image, and a false sky. Topographic expression is vertically exaggerated two times.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data substantially help in analyzing Landsat images by revealing the third dimension of Earth's surface, topographic height. The Landsat archive is managed by the U.S. Geological Survey's Eros Data Center (USGS EDC).

Elevation data used in this image were acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices.

Most of the population of Utah lives just west of the Wasatch Mountains in the north central part of the state. This broad east-northeastward view shows that region with the cities of Ogden, Salt Lake City, and Provo seen from left to right. The Great Salt Lake (left) and Utah Lake (right) are quite shallow and appear greenish in this enhanced natural color view. Thousands of years ago ancient Lake Bonneville covered all of the lowlands seen here. Its former shoreline is clearly seen as a wave-cut bench and/or light colored 'bathtub ring' at several places along the base of the mountain front - evidence seen from space of our ever-changing planet.

This 3-D perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM), a Landsat 5 satellite image mosaic, and a false sky. Topographic expression is exaggerated four times.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and will substantially help in analyzing the large and growing Landsat image archive, managed by the U.S. Geological Survey (USGS).

2000-01-01

This perspective view shows the western side of the volcanically active Kamchatka Peninsula in eastern Russia. The image was generated using the first data collected during the Shuttle Radar Topography Mission (SRTM). In the foreground is the Sea of Okhotsk. Inland from the coast, vegetated floodplains and low relief hills rise toward snow capped peaks. The topographic effects on snow and vegetation distribution are very clear in this near-horizontal view. Forming the skyline is the Sredinnyy Khrebet, the volcanic mountain range that makes up the spine of the peninsula. High resolution SRTM topographic data will be used by geologists to study how volcanoes form and to understand the hazards posed by future eruptions.

This image was generated using topographic data from SRTM and an enhanced true-color image from the Landsat 7 satellite. This image contains about 2,400 meters (7,880 feet) of total relief. The topographic expression was enhanced by adding artificial shading as calculated from the SRTM elevation model. The Landsat data was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota.

NASA Technical Reports Server (NTRS)

2001-01-01

This perspective view shows the city of Bhuj, India, in the foreground near the right side (dark gray area). Bhuj and many other towns and cities nearby were almost completely destroyed by the January 26, 2001, earthquake in western India. This magnitude 7.6 earthquake was the deadliest in the history of India with some 20,000 fatalities and over a million homes damaged or destroyed. The epicenter of the earthquake was in the area in the upper left corner of this view.

The city of Anjar is in the dark gray area near the top center of the image. Anjar was previously damaged by a magnitude 6.1 earthquake in 1956 that killed 152 people and suffered again in the larger 2001 earthquake. The red hills to the left of the center of the image are the Has and Karo Hills, which reach up to 300 meter (900 feet) elevation. These hills are formed by folded red sandstone layers. Geologists are studying these folded layers to determine if they are related to the fault that broke in the 2001 earthquake. The city of Bhuj was the historical capital of the Kachchh region. Highways and rivers appear as dark lines. Vegetation appears bright green in this false-color Landsat image. The Gulf of Kachchh (or Kutch) is the blue area in the upper right corner of the image, and the gray area on the left side of the image is called the Banni plains.

This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated 5X.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM by the United States

SRTM Perspective View with Landsat Overlay: Costa Rica Coastal Plain

NASA Technical Reports Server (NTRS)

2001-01-01

This perspective view shows the northern coastal plain of Costa Rica with the Cordillera Central, composed of a number of active and dormant volcanoes, rising in the background. This view looks toward the south over the Rio San Juan, which marks the boundary between Costa Rica and Nicaragua. The smaller river joining Rio San Juan in the center of the image is Rio Sarapiqui, which is navigable upstream as far inland as Puerto Viejo (Old Port) de Sarapiqui at the mountain's base. This river was an important transportation route for those few hardy settlers who first moved into this region, although as recently as 1953 a mere three thatched-roof houses were all that comprised the village of Puerto Viejo.

This coastal plain is a sedimentary basin formed about 50 million years ago composed of river alluvium and lahar (mud and ash flow) deposits from the volcanoes of the Cordillera Central. It comprises the province of Heredia (the smallest of Costa Rica's seven) and demonstrates a wide range of climatic conditions, from warm and humid lowlands to cool and damp highlands, and including the mild but seasonally wet and dry Central Valley.

This image was generated in support of the Central American Commission for Environment and Development through an agreement with NASA. The Commission involves eight nations working to develop the Mesoamerican Biological Corridor, an effort to study and preserve some of the most biologically diverse regions of the planet.

This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated 2X.

New Perspectives from Satellite and Profile Observations on Tropospheric Ozone over Africa and the Adjacent Oceans: An Indian-Atlantic Ocean Link to tbe "Ozone Paradox"

NASA Technical Reports Server (NTRS)

Thompson, Anne M.; Witte, Jacquelyn C.; Diab, Roseanne D.; Thouret, Valerie; Sauvage, Bastien; Chatfield, B.; Guan, Hong

2004-01-01

In the past few years, tropospheric ozone observations of Africa and its adjacent ocenas have been greatly enhanced by high resolution (spatial and temporal) satellite measurements and profile data from aircraft (MOZAIC) and balloon-borne (SHADOZ) soundings. These views have demonstrated for the first time the complexity of chemical-dynamical interactions over the African continent and the Indian and Atlantic Oceans. The tropical Atlantic "ozone paradax" refers to the observation that during the season of maximum biomass burning in west Africa north of the Intertropical Convergence Zone (ITCZ), the highest tropospheric ozone total column occurs south of the ITCZ over the tropical Atlantic. The longitudinal view of tropospheric ozone in the southern tropics from SHADOZ (Southern Hemisphere Additional Ozonesondes) soundings shown the persistence of a "zonal-wave one" pattern that reinforces the "ozone paradox". These ozone features interact with dynamics over southern and northern Africa where anthropogenic sources include the industrial regions of the South African Highveld and Mideastern-Mediterranean influences, respectively. Our newest studies with satellites and soundings show that up to half the ozone pollution over the Atlantic in the January-March "paradox" period may originate from south Asian pollution. Individual patches of pollurion over the Indian Ocean are transported upward by convective mixing and are enriched by pyrogenic, biogenic sources and lightning as they cross Africa and descend over the Atlantic. In summary, local sources, intercontinental import and export and unique regional transport patterns put Africa at a crossroads of troposheric ozone influences.

Three dimensional perspective view of false-color image of eastern Hawaii

NASA Technical Reports Server (NTRS)

1994-01-01

This is a three dimensional perspective view of false-color image of the eastern part of the Big Island of Hawaii. It was produced using all three radar frequencies C-Band and L-Band. This view was constructed by overlaying a SIR-C radar image on a U.S. Geological Survey digital elevation map. The image was acquired on April 12, 1994 during the 52nd orbit of the Shuttle Endeavour by the Spaceborne Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR). The area shown is approximately 34 by 57 kilomters with the top of the image pointing toward north-west. The image is centered at about 155.25 degrees west longitude and 19.5 degrees north latitude. Visible in the center of the image in blue are the summit crater (Kilauea Caidera) which contains the smaller Halemaumau Crater, and the line of collapsed craters below them that form the Chain of Craters Road. The rain forest appears bright in the image while green areas correspond to lower vegetation. The lava flows have differen

Skylab (SL)-3 - East Africa View - Ravaged by Drought

NASA Image and Video Library

1973-08-15

S73-35082 (July-Sept. 1973) --- A near vertical view of a portion of west Africa ravaged by drought for the past five years is seen in this Skylab 3 Earth Resources Experiments Package S190-B (five-inch Earth terrain camera) photograph taken from the Skylab space station in Earth orbit. The semi-desert scene is in southeastern Niger about 200 nautical miles east-northeast of the capital city of Niamey. A polygonal-shaped area (dark) in the lower right corner of the picture represents a range-management ranch. The dry stream beds trending diagonally across the photograph locally contain some water or vegetation (green). The beds are sources of water through shallow drilling and contain soils suitable for production of crops. The variety of tans, browns and grays are typical desert colors that represent barren rocks and soil or sand-filled ancient stream valleys. Absence of vegetation is the singular feature of the area. Dr. G. Stuckmann of the Geographic Institute, University of Technology, Mannover, Federal Republic of Germany, will use this photograph in the study of the hydrologic regime of the region through analysis of fossil drainage patterns, geological structures and accumulations of surface water. Federal agencies participating with NASA on the EREP project are the Departments of Agriculture, Commerce, Interior, the Environmental Protection Agency and the Corps of Engineers. All EREP photography is available to the public through the Department of Interior?s Earth Resources Observations Systems Data Center, Sioux Falls, South Dakota, 57198.

Intercultural Communication as Viewed from the Perspective of Cross-cultural Psychology

NASA Astrophysics Data System (ADS)

Niikura, Ryoko

The encounter with foreign nationals in everyday life calls for not only understanding of the other on the level of recognition but also the ability to cope with the whole spectrum of emotional reactions associated with direct experience of other cultures. Viewing the subject from the perspective of cross-cultural psychology, this paper outlines the course of human information processing that restricts cross-cultural personal acceptance and the psychological process involved in contact with other cultures. Building on this basis, it then discusses the significance of understanding other cultures and examines requirements for communication with people who have different cultural backgrounds. A particular focus is the approach to communication with international students in Japanese universities.

“It’s my blood”: ethical complexities in the use, storage and export of biological samples: perspectives from South African research participants

PubMed Central

2014-01-01

Background The use of biological samples in research raises a number of ethical issues in relation to consent, storage, export, benefit sharing and re-use of samples. Participant perspectives have been explored in North America and Europe, with only a few studies reported in Africa. The amount of research being conducted in Africa is growing exponentially with volumes of biological samples being exported from the African continent. In order to investigate the perspectives of African research participants, we conducted a study at research sites in the Western Cape and Gauteng, South Africa. Methods Data were collected using a semi-structured questionnaire that captured both quantitative and qualitative information at 6 research sites in South Africa. Interviews were conducted in English and Afrikaans. Data were analysed both quantitatively and qualitatively. Results Our study indicates that while the majority of participants were supportive of providing samples for research, serious concerns were voiced about future use, benefit sharing and export of samples. While researchers view the provision of biosamples as a donation, participants believe that they still have ownership rights and are therefore in favour of benefit sharing. Almost half of the participants expressed a desire to be re-contacted for consent for future use of their samples. Interesting opinions were expressed with respect to export of samples. Conclusions Eliciting participant perspectives is an important part of community engagement in research involving biological sample collection, export, storage and future use. A tiered consent process appears to be more acceptable to participants in this study. Eliciting opinions of researchers and research ethics committee (REC) members would contribute multiple perspectives. Further research is required to interrogate the concept of ownership and the consent process in research involving biological samples. PMID:24447822

How Many Plumes In Africa ? The Geochemical Point of View

NASA Astrophysics Data System (ADS)

Pik, R.; Marty, B.; Hilton, D.

2004-12-01

Since the Oligocene, volcanic activity in Africa was particularly important in the Horn of Africa where ~ 1 million km3 of continental flood basalts (the Ethiopian CFB) erupted 30 Ma ago in a time interval of 1-2 Ma or less. The Afar volcanic province which is still magmatically active is thought to represent the surface expression of a deep mantle plume, a view consistent with ultra-low velocity anomalies at the base of the mantle beneath the African superswell and the Ethiopia-Afar volcanic province. This plume origin is also supported by the occurrence of 3He/4He ratios up to 20 Ra (Ra is the 3He/4He ratio of atmospheric helium) much higher than those of mid-ocean ridge basalts (on average, 8,b1 Ra) and thought to characterize mantle material originating from below the 660 km discontinuity. However, a deep mantle origin for "high 3He" material is currently questioned by some models which rather ascribe a lithospheric or shallow asthenospheric origin for such He component. The origin of this signal can be tested with the distribution of He isotopic signatures and other geochemical tracers among different African volcanic provinces. All these other provinces exhibit 3He/4He ratios that are equal to, or lower than, the mean MORB ratio of 7-9 Ra (Cameroon line: 5-7 Ra; Hoggar: 8 Ra, this work; Darfur 5.4-7.5 Ra; West African rift: 5-8.5 Ra, this work; Comores, 6.5 Ra, this work). Although low 3He/4He ratios in intraplate volcanic provinces could result from crustal recycling in the mantle and remobilisation of recycled crust during plume uprise, the upper range of 3He/4He values within the field of MORB values points to the strong involvement of asthenospheric mantle and limited interactions of magmas with the aged African crust. Furthermore, these "low-3He" volcanic provinces are characterized by strongly alkaline to undersaturated volcanism indicative of low degrees of partial melting and a thermal regime of the asthenosphere cooler than the one that gave rise to

Perspective View, SRTM / Landsat, Los Angeles, Calif

NASA Technical Reports Server (NTRS)

2002-01-01

Los Angeles, Calif., is one of the world's largest metropolitan areas with a population of about 15 million people. The urban areas mostly cover the coastal plains and lie within the inland valleys. The intervening and adjacent mountains are generally too rugged for much urban development. This in large part because the mountains are 'young', meaning they are still building (and eroding) in this seismically active (earthquake prone) region.

Earthquake faults commonly lie between the mountains and the lowlands. The San Andreas fault, the largest fault in California, likewise divides the very rugged San Gabriel Mountains from the low-relief Mojave Desert, thus forming a straight topographic boundary between the top center and lower right corner of the image. We present two versions of this perspective image from NASA's Shuttle Radar Topography Mission (SRTM): one with and one without a graphic overlay that maps faults that have been active in Late Quaternary times (white lines). The fault database was provided by the U.S. Geological Survey.

For the annotated version of this image, please select Figure 1, below: [figure removed for brevity, see original site] (Large image: 2 mB jpeg)

The Landsat image used here was acquired on May 4, 2001, about seven weeks before the summer solstice, so natural terrain shading is not particularly strong. It is also not especially apparent given a view direction (northwest) nearly parallel to the sun illumination (shadows generally fall on the backsides of mountains). Consequently, topographic shading derived from the SRTM elevation model was added to the Landsat image, with a false sun illumination from the left (southwest). This synthetic shading enhances the appearance of the topography.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and substantially helps in analyzing the large and

Mount San Antonio (more commonly known as Mount Baldy) crowns the San Gabriel Mountains northeast of Los Angeles in this computer-generated east-northeast perspective viewed from above the Malibu coastline. On the right, the Pacific Ocean and Santa Monica are in the foreground. Further away are downtown Los Angeles (appearing grey) and then the San Gabriel Valley, which lies adjacent to the mountain front. The San Fernando Valley appears in the left foreground, separated from the ocean by the Santa Monica Mountains. At 3,068 meters (10,064 feet) Mount Baldy rises above the tree line, exposing bright white rocks that are not snow capped in this early autumn scene.

This 3-D perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM), an enhanced color Landsat 7 satellite image, and a false sky. Topographic expression is exaggerated one and one-half times.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and will substantially help in analyzing the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM project by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, S.D.

Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices.

Wortley, Sally; Tong, Allison; Howard, Kirsten

2017-03-01

Objectives The aim of the present study was to describe community views and perspectives on public engagement processes in Australian health technology assessment (HTA) decision making. Methods Six focus groups were held in Sydney (NSW, Australia) as part of a broad program of work on public engagement and HTA. Eligible participants were aged ≥18 years and spoke English. Participants were asked about their views and perspectives of public engagement in the HTA decision-making process, with responses analysed using a public participation framework. Results Fifty-eight participants aged 19-71 years attended the focus groups. Responses from the public indicated that they wanted public engagement in HTA to include a diversity of individuals, be independent and transparent, involve individuals early in the process and ensure that public input is meaningful and useful to the process. This was consistent with the public participation framework. Perceived shortcomings of the current public engagement process were also identified, namely the lack of awareness of the HTA system in the general population and the need to acknowledge the role different groups of stakeholders or 'publics' can have in the process. Conclusions The public do see a role for themselves in the HTA decision-making process. This is distinct to the involvement of patients and carers. It is important that any future public engagement strategy in this field distinguishes between stakeholder groups and outline approaches that will involve members of the public in the decision-making process, especially if public expectations of involvement in healthcare decision-making continue to increase. What is known about this topic? The views and perspectives of patients and consumers are important in the HTA decision-making process. There is a move to involve the broader community, particularly as decisions become increasingly complex and resources more scarce. What does this paper add? It not been known to what

HIV and AIDS in Africa: social, political, and economic realities.

PubMed

Dhai, A

2008-01-01

Sub-Saharan Africa bears the brunt of the HIV epidemic, which is fueled by the many ethical, social, and political complexities that make up Africa. In turn, the pandemic has also caused many ethical, social, and political complexities that Africa now grapples with. Being infected with HIV is highly complex and challenging. Regrettably, gender inequality is still pervasive in Africa. The response by African leaders to the pandemic has been, on the whole, shamefully lethargic. For Africa to win its war against HIV/AIDS, a paradigm shift is required from the perspective of its socio-political context. What is called for is positive political will that will address all aspects of the social determinants of AIDS. What is also required is that Ubuntu is embraced meaningfully.

Multi-perspective views of students’ difficulties with one-dimensional vector and two-dimensional vector

Researchers of students’ conceptual change usually collects data from written tests and interviews. Moreover, reports of conceptual change often simply refer to changes in concepts, such as on a test, without any identification of the learning processes that have taken place. Research has shown that students have difficulties with vectors in university introductory physics courses and high school physics courses. In this study, we intended to explore students’ understanding of one-dimensional and two-dimensional vector in multi perspective views. In this research, we explore students’ understanding through test perspective and interviews perspective. Our research study adopted the mixed-methodology design. The participants of this research were sixty students of third semester of physics education department. The data of this research were collected by testand interviews. In this study, we divided the students’ understanding of one-dimensional vector and two-dimensional vector in two categories, namely vector skills of the addition of one-dimensionaland two-dimensional vector and the relation between vector skills and conceptual understanding. From the investigation, only 44% of students provided correct answer for vector skills of the addition of one-dimensional and two-dimensional vector and only 27% students provided correct answer for the relation between vector skills and conceptual understanding.

A retrospective view on the viability of water fluoridation in South Africa to prevent dental caries.

Kroon, Jeroen; Van Wyk, Philippus Johannes

2012-10-01

Despite a Commission of Inquiry into water fluoridation recommending the fluoridation of public water supplies to the optimal fluoride concentration of 0.7 ppm, as well as regulations for the introduction of water fluoridation which compel water providers to fluoridate public water supplies, no artificially fluoridated water scheme exists in South Africa. In view of concerns expressed by South African local authorities about cost and reports urging further investigation into the effectiveness of water fluoridation, the aim of this study was to determine whether water fluoridation is still a viable option to reduce dental caries in South Africa. A model based on a cost evaluation of 44 communities in Florida, United States, and applied to South Africa was used as the basis for this study. Twenty-three input variables were used to create a computerized model which was populated with 2006 and 2011 data. Per capita cost, cost-effectiveness ratio and cost-benefit ratio were calculated as economic outputs to facilitate decision making for projected caries reductions of 15%, 30% and 50%. The average per capita cost of water fluoridation for all category water providers combined is US$0.28 in 2006 and US$0.35 in 2011, an increase of 23.2% over this period. The average cost-effectiveness for all water providers combined varies from US$3.32 for a 50% to US$11.08 for a 15% caries reduction. Despite higher cost-effective values for some cities and towns, the cost per person per year to save one Decayed, Missing or Filled Tooth (DMFT) at a projected caries reduction of at least 15% as a result of the introduction of water fluoridation, is at least 48.4% less than the cost of a two surface restoration. The average cost-benefit for all water providers combined varies from 0.1 at a 50% to 0.34 at a 15% caries reduction. For both cost-effectiveness and cost-benefit ratio better results are achieved when the projected caries reduction increases. The results of this study show that

SRTM Perspective View with Landsat Overlay: San Joaquin Valley, California

NASA Technical Reports Server (NTRS)

2000-01-01

San Joaquin, the name given to the southern portion of California's vast Central Valley, has been called the world's richest agricultural valley. In this perspective view generated using data from the Shuttle Radar Topography Mission and an enhanced Landsat image, we are looking toward the southwest over a checkerboard pattern of agricultural fields. Mt. Pinos, a popular location for stargazing at 2,692 meters (8,831 feet) looms above the valley floor and is visible on the left side of the image. The productive southern San Joaquin is in reality a desert, averaging less than 12.7 cm (5 inches) of rain per year. Through canals and irrigation, the region nurtures some two hundred crops including grapes, figs, apricots, oranges, and more than 4,047 square-km (1,000,000 acres) of cotton. The California Aqueduct, transporting water from the Sacramento River Delta through the San Joaquin, runs along the base of the low-lying Wheeler Ridge on the left side of the image. The valley is not all agriculture though. Kern County, near the valley's southern end, is the United States' number one oil producing county, and actually produces more crude oil than Oklahoma. For visualization purposes, topographic heights displayed in this image are exaggerated two times. Colors, from Landsat data, approximate natural color.

The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994.

Population research potentials in Africa.

PubMed

Hyden, G

1980-01-01

There is a need in Africa to test prevailing theories and concepts in population studies to see how they apply to this culture. Most of the prevailing perspective on population issues can be influenced by development strategies and policies affecting demographic variables. So research designed to determine the longterm consequences of rural settlement policies on subsequent access to family planning or family planning policies are also needed, as are studies which zero in on the work and results of specific population projects. The following issues are considered worth special consideration in Africa, where the vast majority of women live in rural areas where family planning services will not reach for some time. The areas of investigation which seem most pertinent in sub-saharan Africa are: side effect of contraceptive devices and agents; infertility assessments, social and medical consequences of adolescent pregnancies, the means of offering effective population education in rural African areas, the possible effects of fertility control programs on demographic transition, and potential funding sources.

Perspective View, Radar Image, Color as Height, Molokai, Lanai and Maui, Hawaii

NASA Technical Reports Server (NTRS)

2000-01-01

This perspective view shows three Hawaiian islands: Molokai (lower left), Lanai (right), and the northwest tip of Maui (upper left). Data such as these will be useful for studying the history of volcanic activity on these now extinct volcanoes. SRTM data also will help local officials evaluate and mitigate natural hazards for islands throughout the Pacific. For example, improved elevation data will make it easier for communities to plan for tsunamis (tidal waves generated by earthquakes around the perimeter of the Pacific) by helping them identify evacuation routes and areas prone to flooding.

This perspective view combines two types of data from the Shuttle Radar Topography Mission. The image brightness corresponds to the strength of the radar signal reflected from the ground, while colors show the elevation as measured by SRTM. Colors range from blue at the lowest elevations to white at the highest elevations. This image contains 1800 meters (5900 feet) of total relief.

The Shuttle Radar Topography Mission (SRTM), launched on February 11,2000, uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. The mission is designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, an additional C-band imaging antenna and improved tracking and navigation devices.

Child mental-health policy development in sub-Saharan Africa: broadening the perspectives using Bronfenbrenner's ecological model.

PubMed

Atilola, Olayinka

2017-04-01

Despite socio-economic, demographic and epidemiological facts and realities that point to a potential risk for explosion in the prevalence of childhood mental health problems in sub-Saharan Africa, there is still a severe dearth of child and adolescent mental health (CAMH) policy or strategy to respond to the situation in the region. Unfortunately, current attempts at suggesting courses of action in this regard appear to be focused on narrow reactionary approaches. There is a need for theoretical frameworks to capture the full ramification of childhood in sub-Saharan Africa, from which multi-level, context-appropriate and holistic CAMH policy directions can be understood. In this commentary, we propose an amended version of the Bronfenbrenner's ecological model of childhood as such framework that captures proximal, intermediate and distal factors that influence the care environment of children. We then used the insights provided by the model to identify and prioritize intervention points and appropriate intervention strategies in charting a tentative course for CAMH policy development in the region. Though the ecological model provides a distinct perspective to the structure and dynamics of the care environment of children, the proposed framework using the model is still largely theoretical and need to be further integrated into future studies on CAMH policy development in the region. © The Author 2014.

Existing ethics guidelines, influential literature and policies on ethical research generally focus on real-time data collection from humans. They enforce individual rights and liberties, thereby lowering need for aggregate protections. Although dependable, emerging public health research paradigms like research using public health data (RUPD) raise new challenges to their application. Unlike traditional research, RUPD is population-based, aligned to public health activities, and often reliant on pre-collected longitudinal data. These characteristics, when considered in relation to the generally lower protective ethico-legal frameworks of the Global South, including Africa, highlight ethical gaps. Health and demographic surveillance systems are examples of public health programs that accommodate RUPD in these contexts. We set out to explore the perspectives of professionals with a working knowledge of these systems to determine practical ways of appropriating the foundational principles of health research to advance the ever growing opportunities in RUPD. We present their perspectives and in relation to the literature and our ethical analysis, make context relevant recommendations. We further argue for the development of a framework founded on the discussions and recommendations as a minimum base for achieving optimal ethics for optimal RUPD in the Global South. © 2016 John Wiley & Sons Ltd.

3-D Perspective View, Miquelon and Saint Pierre Islands

NASA Technical Reports Server (NTRS)

2000-01-01

This image shows Miquelon and Saint Pierre Islands, located south of Newfoundland, Canada. These islands, along with five smaller islands, are a self-governing territory of France. North is in the top right corner of the image. The island of Miquelon, in the background, is divided by a thin barrier beach into Petite Miquelon on the left, and Grande Miquelon on the right. Saint Pierre Island is seen in the foreground. The maximum elevation of this land is 240 meters (787 feet). The land mass of the islands is about 242square kilometers (94 square miles) or 1.5 times the size of Washington, DC.

This three-dimensional perspective view is one of several still photographs taken from a simulated flyover of the islands. It shows how elevation data collected by the Shuttle Radar Topography Mission (SRTM) can be used to enhance other satellite images. Color and natural shading are provided by a Landsat 7 image taken on September 7, 1999. The Landsat image was draped over the SRTM data. Terrain perspective and shading are from SRTM. The vertical scale has been increased six times to make it easier to see the small features. This also makes the sea cliffs around the edges of the islands look larger. In this view the capital city of Saint Pierre is seen as the bright area in the foreground of the island. The thin bright line seen in the water is a breakwater that offers some walled protection for the coastal city.

Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11,2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface.

2002-01-01

This SeaWiFS true-color image acquired over Southern Africa on Sept. 4, 2000, shows a thick shroud of smoke and haze blanketing much of the southern half of the continent. The smoke in this scene is being generated by a tremendous number of fires burning over a large area across the countries of Angola, Zambia, Mozambique, Zimbabwe, Botswana, and the Northern Province of South Africa. In this image, the smoke (grey pixels) is easily distinguished from clouds (bright white pixels). Refer to the Images and Data section for a larger scale view of the fires in Southern Africa. Data from both the SeaWiFS and Terra satellites are being used by an international team of scientists participating in the SAFARI field experiment. The objective of SAFARI is to measure the effects of windblown smoke and dust on air quality and the Earth's radiant energy budget. This image was produced using SeaWiFS channels 6, 5, and 1 (centered at 670 nm, 555 nm , and 412 nm, respectively). The data were acquired and provided by the Satellite Applications Center in Pretoria, South Africa. Image courtesy Gene Feldman, SeaWiFS Project and Orbital Sciences

Malaria programme personnel's experiences, perceived barriers and facilitators to implementing malaria elimination strategy in South Africa.

2018-01-10

South Africa has set an ambitious goal targeting to eliminate malaria by 2018, which is consistent with the United Nations Sustainable Development Goals' call to end the epidemic of malaria by 2030 across the globe. There are conflicting views regarding the feasibility of malaria elimination, and furthermore studies investigating malaria programme personnel's perspectives on strategy implementation are lacking. The study was a cross-sectional survey conducted in 2014 through a face-to-face investigator-administered semi-structured questionnaire to all eligible and consenting malaria programme personnel (team leader to senior manager levels) in three malaria endemic provinces (KwaZulu-Natal, Mpumalanga, and Limpopo) of South Africa. The overall response rate was 88.6% (148/167) among all eligible malaria personnel. The mean age of participants was 47 years (SD 9.7, range 27-70), and the mean work experience of 19.4 years (SD 11.1, range 0-42). The majority were male (78.4%), and 66.9% had secondary level education. Awareness of the malaria elimination policy was high (99.3%), but 89% contended that they were never consulted when the policy was formulated and few had either seen (29.9%) or read (23%) the policy, either in full or in part. Having read the policy was positively associated with professional job designations (managers, EHPs and entomologists) (p = 0.010) and tertiary level education (p = 0.042). There was a sentiment that the policy was neither sufficiently disseminated to all key healthcare workers (76.4%) nor properly adapted (68.9%) for the local operational context in the elimination strategy. Most (89.1%) participants were not optimistic about eliminating malaria by 2018, as they viewed the elimination strategy in South Africa as too theoretical with unrealistic targets. Other identified barriers included inadequate resources (53.5%) and high cross-border movements (19.8%). Most participants were not positive that South Africa could achieve

Adolescents and young people account for 40% of all new HIV infections each year, with South Africa one of the hardest hit countries, and having the largest population of people living with HIV. Although adolescent HIV prevention has been delivered through diverse modalities in South Africa, and although family-based approaches for adolescent HIV prevention have great potential for highly affected settings such as South Africa, there is a scarcity of empirically tested family-based adolescent HIV preventive interventions in this setting. We therefore conducted focus groups and in-depth interviews with key informants including clinicians, researchers, and other individuals representing organizations providing HIV and related health services to adolescents and parents (N = 82). We explored family perspectives and interactions around topics such as communication about sex, HIV, and relationships. Participants described aspects of family interactions that presented both challenges and opportunities for family-based adolescent HIV prevention. Parent-child communication on sexual topics were taboo, with these conversations perceived by some adults as an invitation for children to engage in HIV risk behavior. Parents experienced social sanctions for discussing sex and adolescents who asked about sex were often viewed as disrespectful and needing discipline. However, participants also identified context-appropriate strategies for addressing family challenges around HIV prevention including family meetings, communal parenting, building efficacy around parent-adolescent communication around sexual topics, and the need to strengthen family bonding and positive parenting. Findings indicate the need for a family intervention and identify strategies for development of family-based interventions for adolescent HIV prevention. These findings will inform design of a family intervention to be tested in a randomized pilot trial (ClinicalTrials.gov #NCT02432352).

Cape Province, South Africa as seen from STS-58

1993-10-30

STS058-77-083 (18 Oct-1 Nov 1993) --- In this scene of the south coast of Africa, Cape Agulhas, the southernmost point on the continent, appears as the leftmost cape. Viewed with the Earth's limb top left, clouds at bottom, the view direction is west and north top right. The Cape of Good Hope, with Cape Town nearby, is the thin spike beyond. The great bay in the foreground is Algoa Bay with the city of Port Elizabeth. This was the first time European voyagers are known to have rounded the Cape of Good Hope in their quest to reach India by sea. The entire fold mountain belt of southern Africa is visible: these mountains appear as green (forested) wavy structures stretching west form the foreground, to the Cape of Good Hope, and then northwards some distance. One theory about their origin is that the Falkland Plateau, now an undersea extension of South America, was jostled up against Africa more than 150 million years ago, in times before the Atlantic Ocean existed, before Africa and South America drifted apart from one another. The jostling caused the evolution of the fold mountain belt.

SRTM Perspective View with Landsat Overlay: San Fernando Valley, California

NASA Technical Reports Server (NTRS)

2000-01-01

The San Fernando Valley (lower right of center) is part of Los Angeles and includes well over one million people. Two major disasters have occurred here in the last few decades: the 1971 Sylmar earthquake and the 1994 Northridge earthquake. Both quakes caused major damage to homes, freeways, and other structures and included major injuries and fatalities. The Northridge earthquake was the one of the costliest natural disasters in United States history. Understanding earthquake risks requires understanding a location's geophysical setting, and topographic data are of substantial benefit in that regard. Landforms are often characteristic of specific tectonic processes, such as ground movement along faults. Elevation models, such as those produced by the Shuttle Radar Topography Mission (SRTM), are particularly useful in visualizing regional scale landforms that are too large to be seen directly on-site. They can also be used to model the propagation of damaging seismic waves, which helps in urban planning. In recent years, elevation models have also been a critical input to radar interferometric studies, which reveal detailed patterns of ground deformation from earthquakes that had never before been seen.

This perspective view was generated by draping a Landsat satellite image over a preliminary topographic map from SRTM. Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive.

The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect

Venus - 3D Perspective View of Latona Corona and Dali Chasma

NASA Technical Reports Server (NTRS)

1992-01-01

This computer-generated perspective view of Latona Corona and Dali Chasma on Venus shows Magellan radar data superimposed on topography. The view is from the northeast and vertical exaggeration is 10 times. Exaggeration of relief is a common tool scientists use to detect relationships between structure (i.e. faults and fractures) and topography. Latona Corona, a circular feature approximately 1,000 kilometers (620 miles) in diameter whose eastern half is shown at the left of the image, has a relatively smooth, radar-bright raised rim. Bright lines or fractures within the corona appear to radiate away from its center toward the rim. The rest of the bright fractures in the area are associated with the relatively deep (approximately 3 kilometers or 1.9 miles) troughs of Dali Chasma. The Dali and Diana Chasma system consist of deep troughs that extend for 7,400 kilometers (4,588 miles) and are very distinct features on Venus. Those chasma connect the Ovda and Thetis highlands with the large volcanoes at Atla Regio and thus are considered to be the 'Scorpion Tail' of Aphrodite Terra. The broad, curving scarp resembles some of Earth's subduction zones where crustal plates are pushed over each other. The radar-bright surface at the highest elevation along the scarp is similar to surfaces in other elevated regions where some metallic mineral such as pyrite (fool's gold) may occur on the surface.

Perspectives of intellectual disability in Africa: epidemiology and policy services for children and adults.

Njenga, Frank

2009-09-01

To establish the nature of publications emanating from or relating to intellectual disability in Africa in the previous 12-18 months, and to critically analyse the nature and content of any new knowledge arising from them. Three papers satisfied the criteria set, one from Nigeria on epilepsy and intellectual disability, the other two were from South Africa. Kromberg's paper puts intellectual disability in context for South Africa, emphasizing the role potentially played by traditional healers. Pillay's paper tackles emerging issues in the psycholegal arena in South Africa, many of which are relevant to the rest of the continent. Of the many challenges facing persons with intellectual disability in Africa, high prevalence, discrimination, and access to justice and education are key considerations, in all countries, and without exception are coupled with poor resource allocation. The challenges posed by HIV, wars and internal displacement are significant and demand examination by researchers. Opportunities for beneficial research exist between Africa and the centres of academic excellence around the rest of the world. Those centres with the skill and will to collaborate with Africa will be handsomely rewarded by the wide scope of challenges in intellectual disability that are available for scientific enquiry. Opportunities for skills transfer are many and available.

Primary care clinical practice guidelines in South Africa: qualitative study exploring perspectives of national stakeholders.

Clinical practice guidelines (CPGs) are common tools in policy and clinical practice informing clinical decisions at the bedside, governance of health facilities, health insurer and government spending, and patient choices. South Africa's health sector is transitioning to a national health insurance system, aiming to build on other primary health care initiatives to transform the previously segregated, inequitable services. Within these plans CPGs are an integral tool for delivering standardised and cost effective care. Currently, there is no accepted standard approach to developing, adapting or implementing CPGs efficiently or effectively in South Africa. We explored the current players; drivers; and the context and processes of primary care CPG development from the perspective of stakeholders operating at national level. We used a qualitative approach. Sampling was initially purposeful, followed by snowballing and further sampling to reach representivity of primary care service providers. Individual in-depth interviews were recorded and transcribed verbatim. We used thematic content analysis to analyse the data. We conducted 37 in-depth interviews from June 2014-July 2015. We found CPG development and implementation were hampered by lack of human and funding resources for technical and methodological work; fragmentation between groups, and between national and provincial health sectors; and lack of agreed systems for CPG development and implementation. Some CPG contributors steadfastly work to improve processes aiming to enhance communication, use of evidence, and transparency to ensure credible guidance is produced. Many interviewed had shared values, and were driven to address inequity, however, resource gaps were perceived to create an enabling environment for commercial interests or personal agendas to drive the CPG development process. Our findings identified strengths and gaps in CPG development processes, and a need for national standards to guide CPG

The integrated chronic disease management (ICDM) model was introduced as a response to the dual burden of HIV/AIDS and non-communicable diseases (NCDs) in South Africa, one of the first of such efforts by an African Ministry of Health. The aim of the ICDM model is to leverage HIV programme innovations to improve the quality of chronic disease care. There is a dearth of literature on the perspectives of healthcare providers and users on the quality of care in the novel ICDM model. This paper describes the viewpoints of operational managers and patients regarding quality of care in the ICDM model. In 2013, we conducted a case study of the seven PHC facilities in the rural Agincourt sub-district in northeast South Africa. Focus group discussions (n = 8) were used to obtain data from 56 purposively selected patients ≥18 years. In-depth interviews were conducted with operational managers of each facility and the sub-district health manager. Donabedian’s structure, process and outcome theory for service quality evaluation underpinned the conceptual framework in this study. Qualitative data were analysed, with MAXQDA 2 software, to identify 17 a priori dimensions of care and unanticipated themes that emerged during the analysis. The manager and patient narratives showed the inadequacies in structure (malfunctioning blood pressure machines and staff shortage); process (irregular prepacking of drugs); and outcome (long waiting times). There was discordance between managers and patients regarding reasons for long patient waiting time which managers attributed to staff shortage and missed appointments, while patients ascribed it to late arrival of managers to the clinics. Patients reported anti-hypertension drug stock-outs (structure); sub-optimal defaulter-tracing (process); rigid clinic appointment system (process). Emerging themes showed that patients reported HIV stigmatisation in the community due to defaulter-tracing activities of home-based carers, while

Background Teenage pregnancy is a global social health concern especially because of the HIV and AIDS pandemic, sexually transmitted infections, high rate of termination of pregnancy (TOP), adolescents’ parenthood and decreased level of contraceptives. Aim To explore the views of teenagers on the TOP at Muyexe high school in a rural village of Mopani District, Limpopo Province. Setting Muyexe high school in a rural village of Mopani District, Limpopo Province, in South Africa. Methodology A qualitative method using explorative and descriptive designs was used to find in-depth description and understanding of teenagers’ views on TOP. The target population was girls aged 15–19 years at Muyexe high school in Mopani District. Non-probability, convenient sampling was used to select high school teenage girls who had undergone TOP for the study. Data were collected using individual self-report technique (interview). Tesch’s eight steps of qualitative data analysis were used. Measures to ensure trustworthiness and ethical considerations were observed. Results Two major themes were revealed: (1) Views of teenagers regarding TOP (poverty, relationship problems and single parenthood, negative impact on the teen’s life while attending school) and (2) teenager’s fears regarding pregnancy (stigma, fear of parents and friends, rape and incest and fear of giving birth). Conclusion Majority of participants had knowledge about TOP; some had experiences about TOP while others held inadequate knowledge. Recommendations were based on the findings by teaching dangers of TOP and various contraceptive methods to prevent unwanted pregnancies and TOP. PMID:27380849

Enhancing access to health information in Africa: a librarian's perspective.

PubMed

Gathoni, Nasra

2012-01-01

In recent years, tremendous progress has been made toward providing health information in Africa, in part because of technological advancements. Nevertheless, ensuring that information is accessible, comprehensible, and usable remains problematic, and there remain needs in many settings to address issues such as computer skills, literacy, and the infrastructure to access information. To determine how librarians might play a more strategic role in meeting information needs of health professionals in Africa, the author reviewed key components of information systems pertinent to knowledge management for the health sector, including access to global online resources, capacity to use computer technology for information retrieval, information literacy, and the potential for professional networks to play a role in improving access to and use of information. The author concluded that, in regions that lack adequate information systems, librarians could apply their knowledge and skills to facilitate access and use by information seekers. Ensuring access to and use of health information can also be achieved by engaging organizations and associations working to enhance access to health information, such as the Association for Health Information and Libraries in Africa. These groups can provide assistance through training, dissemination, information repackaging, and other approaches known to improve information literacy.

DrosAfrica: Building an African biomedical research community using Drosophila.

PubMed

Martín-Bermudo, María D; Gebel, Luka; Palacios, Isabel M

2017-10-01

The impact that research has on shaping the future of societies is perhaps as significant as never before. One of the problems for most regions in Africa is poor quality and quantity of research-based education, as well as low level of funding. Hence, African researchers produce only around one percent of the world's research. We believe that research with Drosophila melanogaster can contribute to changing that. As seen before in other places, Drosophila can be used as a powerful and cost-effective model system to scale-up and improve both academia and research output. The DrosAfrica project was founded to train and establish a connected community of researchers using Drosophila as a model system to investigate biomedical problems in Africa. Since founding, the project has trained eighty scientists from numerous African countries, and continues to grow. Here, we describe the DrosAfrica project, its conception and its mission. We also give detailed insights into DrosAfrica's approaches to achieve its aims, as well as future perspectives, and opportunities beyond Africa. Copyright © 2017 Elsevier Ltd. All rights reserved.

Balogh, K K

2000-01-01

postgraduate training required a prolonged stay abroad, women encountered difficulties in leaving their families behind to improve their career perspectives. Gradually, there has been an increase of possibilities of post-graduate training in the African region as well as the introduction of a modular system and perspectives for training over the internet. These developments will clearly be beneficial for women, as it will enable them to follow post-graduate training without leaving their families for extended periods. Gradually, also female veterinarians in Africa are becoming empowered and recognise their capabilities. The understanding of the importance of gender aspects especially with regard to animal husbandry practices has opened up new opportunities for female veterinarians to work in extension services and as health promoters. The access to further education is the key to expanding their professional perspectives.

SRTM Perspective View with Landsat Overlay: Rann of Kachchh, India

NASA Technical Reports Server (NTRS)

2001-01-01

The earthquake that struck western India on January 26,2001, was the country's strongest in the past 50 years. This perspective view shows the area of the earthquake's epicenter in the lower left corner. The southern Rann of Kachchh appears in the foreground. The Rann is an area of low-lying salt flats that shows up with various shades of white and blue in this false-color Landsat image. The gray area on the middle of the image is called the Banni plains.

The darker blue spots and curving lines in the Rann and the Banni plains are features that appeared after the January earthquake. Their true colors are shades of white and gray, but the infrared data used in the image gives them a blue or turquoise color. These features are the effects of liquefaction of wet soil, sand and mud layers caused by the shaking of the earthquake. The liquefaction beneath the surface causes water to be squeezed out at the surface forming mud volcanoes, sand blows and temporary springs. Some of the residents of this dry area were hopeful that they could use the water, but they found that the water was too salty in almost every place where it came to the surface.

The city of Bhuj, India, appears as a gray area in the upper right of the image. Bhuj and many other towns and cities nearby were almost completely destroyed by the January 2001 earthquake. This magnitude 7.7 earthquake was the deadliest in the history of India with some 20,000 fatalities and over a million homes damaged or destroyed.

HIV treatment initiatives have focused on increasing access to antiretroviral therapy (ART). There is growing evidence, however, that treatment availability alone is insufficient to stop the epidemic. In South Africa, only one third of individuals living with HIV are actually on treatment. Treatment refusal has been identified as a phenomenon among people who are asymptomatic, however, factors driving refusal remain poorly understood. We interviewed 50 purposively sampled participants who presented for voluntary counseling and testing in Soweto to elicit a broad range of detailed perspectives on ART refusal. We then integrated our core findings into an explanatory framework. Participants described feeling “too healthy” to start treatment, despite often having a diagnosis of AIDS. This subjective view of wellness was framed within the context of treatment being reserved for the sick. Taking ART could also lead to unintended disclosure and social isolation. These data provide a novel explanatory model of treatment refusal, recognizing perceived risks and social costs incurred when disclosing one’s status through treatment initiation. Our findings suggest that improving engagement in care for people living with HIV in South Africa will require optimizing social integration and connectivity for those who test positive.

2014-02-01

Pharmacogenomics has an important role in the evolution of personalized medicine, and its widespread uptake may ultimately depend on the interests and perspectives of key players in health care. Our aim was to summarize studies on stakeholder perspectives and attitudes toward pharmacogenomic testing. Thus, we conducted a review of original research studies that reported stakeholder views on pharmacogenomic testing using a structured approach in PubMed, International Pharmaceutical Abstracts, Cumulative Index to Nursing and Allied Health Literature, and EMBASE. A standardized data abstraction form was developed that included stakeholder group of interest-patients, general public, providers, and payers. Stakeholder views regarding barriers to pharmacogenetic implementation were organized into the following themes: ancillary information-related, clinical, economic, educational, ethical or legal, medical mistrust, and practicality. Of 34 studies that met our inclusion criteria, 37 perspectives were reported (15 on providers, 9 on the general public, 9 on patients, and 4 on payers). The most common topics that arose in studies of providers related to clinical usefulness of genetic data (n=11) and educational needs (n=11). Among the general public, the most common concerns were medical mistrust (n=5), insufficient education (n=5), and practicality (n=5). The most prevalent issues from the patient perspective were ethical or legal (n=6) and economic (n=5) issues. Among payers, leading issues were practicality (n=4) and clinical usefulness (n=3). There was overlap in the topics and concerns across stakeholder perspectives, including lack of knowledge about pharmacogenomic testing. Views on issues related to privacy, cost, and test result dissemination varied by stakeholder perspective. Limited research had been conducted in underrepresented groups. Efforts to address the issues raised by stakeholders may facilitate the implementation of pharmacogenomic testing into

"Some Africans Gave Full Approval of Homosexuality": Representations of Africa in the U.S. Homophile Press, 1953-1964.

PubMed

Thompson, Healy

2017-01-01

This essay explores representations of Africa in the three primary U.S. homophile periodicals of the 1950s and early 1960s. It considers 130 articles, letters, and stories in Mattachine Review, ONE, and The Ladder that mentioned Africa or Africans. In doing so, it explores and analyzes the ways that Africa was referenced and represented to understand how those periodicals, their writers, and the U.S. homophile movement understood and were influenced by Africa (or by their perceptions of Africa). The essay argues that views expressed in The Ladder, Mattachine Review, and ONE reflected broader thinking about Africa in the 1950s and early 1960s in focusing on Egypt, relying on U.S. accounts of Africa, and eroticizing the bodies of Africans. But homophile publications also differed from their mainstream counterparts by presenting various African cultures as superior to U.S. culture in their liberal views of and approaches to sexual and gender variance.

SRTM Perspective View with Landsat Overlay: Caliente Range and Cuyama Valley, California

NASA Technical Reports Server (NTRS)

2001-01-01

Before the arrival of Europeans, California's Cuyama Valley was inhabited by Native Americans who were culturally and politically tied to the Chumash tribes of coastal Santa Barbara County. Centuries later, the area remains the site of noted Native American rock art paintings. In the 1800s, when Europeans established large cattle and horse-breeding ranches in the valley, the early settlers reported the presence of small villages along the Cuyama River. This perspective view looks upstream toward the southeast through the Cuyama Valley. The Caliente Range, with maximum elevations of 1,550 meters (5,085 feet), borders the valley on the left. The Cuyama River, seen as a bright meandering line on the valley floor, enters the valley from headwaters more than 2,438 meters (8,000 feet) above sea level near Mount Abel and flows 154 kilometers (96 miles) before emptying into the Pacific Ocean. The river's course has been determined in large part by displacement along numerous faults.

Today, the Cuyama Valley is the home of large ranches and small farms. The area has a population of 1,120 and is more than an hour and a half drive from the nearest city in the county.

Prominently displayed in this image, Mt. Pinos, at 2,692 meters (8,831 feet) is the highest peak in the Los Padres National Forest. Named for the mantle of pine trees covering its slopes and summit, it offers one of the best stargazing sites in Southern California. Shuttle Radar Topography Mission (SRTM) elevation data were combined with Landsat data to generate this perspective view looking toward the northwest. Not only is the mountain popular with astronomers and astro-photographers, it is also popular for hiking trails and winter sports.

The broad low relief area in the right foreground is Cuddy Valley. Cuddy Valley Road is the bright line on the right (north)side of the valley. Just to the left and paralleling the road is a scarp (cliff) formed by the San Andreas fault. The fault slices through the mountains here and then bends and continues onto the Carrizo Plain (right center horizon). This entire segment of the San Andreas fault broke in a major earthquake in 1857.

Aims of education in South Africa

NASA Astrophysics Data System (ADS)

Morrow, Walter Eugene

1990-06-01

The first part of this paper gives a historical account of the aims of education under Apartheid, and discusses the ideological success of Apartheid education. The second part argues that a significant discussion — that is one which could have some purchase on schooling policy and educational practice — of aims of education in South Africa is not possible at present because the historical preconditions for such a discussion are not satisfied. It is argued that Apartheid has generated a political perspective which is unsympathetic to a discussion of aims of education; that the dominance of a social engineering model of schooling distorts a discussion of aims of education; and that a shared moral discourse, which is a necessary condition for a significant discussion of aims of education, does not yet exist in South Africa.

Examining the potential impacts of climate change on international security: EU-Africa partnership on climate change.

PubMed

Dodo, Mahamat K

2014-01-01

Climate Change like many global problems nowadays is recognized as a threat to the international security and cooperation. In theoretical terms, it is being securitized and included in the traditional security studies. Climate change and its accompanying environmental degradation are perceived to be a threat that can have incalculable consequences on the international community. The consequences are said to have more effects in small island developing nations and Africa where many States are fragile and overwhelmed with mounting challenges. In recent years, the security implications of the climate change are being addressed from national, regional and multilateral level. Against this backdrop, this paper intends to contribute to the debate on climate change and international security and present a broader perspective on the discussion. The paper will draw from the EU-Africa partnership on climate change and is structured as follows: the first part introduces the background of the international climate change policy and its securitization, the second part covers the EU-Africa relations and EU-Africa partnership on climate change, and the third part discusses the Congo Basin Forest Partnership as a concrete example of EU-Africa Partnership on Climate Change. Lastly, the paper concludes by drawing some conclusions and offers some policy perspectives and recommendations. Q54; 055; 052; 01;

The Consortium for NCD Prevention and Control in Sub-Saharan Africa (CNCD-Africa): from concept to practice.

PubMed

Amuyunzu-Nyamongo, Mary; Owuor, Jared O; Blanchard, Claire

2013-12-01

CNCD-Africa was established in July 2009 in response to and in recognition of the continuously increasing burden of diseases such as injuries, non-communicable diseases (NCDs) and mental health in low- and middle-income countries, and specifically in countries of sub-Saharan Africa. CNCD-Africa aims to comprehensively address specific and common objectives while building capacity in the region to prevent and control NCDs. With support from key partners and funders, and a keen interest in opportunities to address NCDs from health promotion and equity perspectives, the Consortium has excelled in four key areas: convening; knowledge generation and sharing; advocacy; and networking. However, the path to successful and sustainable efforts remains laden with challenges and barriers. Retaining interest of network partners through flagship efforts and continued efforts to ascertain support from local and international partners with interest in NCDs across the region remain essential to CNCD-Africa core activities. A key lesson learnt from the early years of CNCD-Africa is that existing regional platforms can and should be used to showcase what is being done locally, and to share best practices and best-buys. In addition, partnerships and stakeholder involvement have been key for CNCD-Africa and are essential to NCD action. Sustaining such partnerships requires incentives for the various partners to keep actively involved in NCD action. This can be achieved through joint inception, project planning, implementation, monitoring and evaluation. Another ingredient for success seems to be innovative financing for NCD efforts, which is possible through the establishment and sustaining of regional and global partnerships that are robust, locally relevant and respond to country needs.

Perspective traffic display format and airline pilot traffic avoidance

NASA Technical Reports Server (NTRS)

Ellis, Stephen R.; Mcgreevy, Michael W.; Hitchcock, Robert J.

1987-01-01

Part-task experiments have examined perspective projections of cockpit displays of traffic information as a means of presenting aircraft separation information to airline pilots. Ten airline pilots served as subjects in an experiment comparing the perspective projection with plan-view projections of the same air traffic situations. The pilots' task was to monitor the traffic display in order to decide if an avoidance maneuver was needed. Pilots took more time to select avoidance maneuvers with a conventional plan-view display than with an experimental perspective display. In contrast to previous results, if the pilots selected a maneuver with the perspective display, they were more likely to choose one with a vertical component. Tabulation of the outcomes of their initial avoidance decisions with both perspective and plan-view displays showed that they were more likely to achieve required separation with maneuvers chosen with the aid of perspective displays.

A change in job responsibilities from library manager to hospital administrator provides this year's Doe lecturer the opportunity to reflect on the values of the library profession from a fresh perspective. Librarians play a unique role and remain vital to the health care enterprise but are frequently misunderstood. Their role can be viewed from three angles: service, technology, and a unique sort of professionalism. Librarians must focus their service priorities on the needs of the institution, while remaining true to their own unique professional values. They must be advocates for the appropriate use of technology in support of those service roles. The passion that many librarians bring to their jobs makes librarianship a vocation as much as a profession. The mission and vision developed by the American Society of Health-System Pharmacists in 2001 provides a useful model for defining a personal professional mission and vision. PMID:12568154

To date, the earliest modern human fossils found outside of Africa are dated to around 90,000 to 120,000 years ago at the Levantine sites of Skhul and Qafzeh. A maxilla and associated dentition recently discovered at Misliya Cave, Israel, was dated to 177,000 to 194,000 years ago, suggesting that members of the Homo sapiens clade left Africa earlier than previously thought. This finding changes our view on modern human dispersal and is consistent with recent genetic studies, which have posited the possibility of an earlier dispersal of Homo sapiens around 220,000 years ago. The Misliya maxilla is associated with full-fledged Levallois technology in the Levant, suggesting that the emergence of this technology is linked to the appearance of Homo sapiens in the region, as has been documented in Africa.

The railroad and highway connecting the two countries is seen as a ribbon crossing the corner of the view. The broad color difference between strong browns/reds in the northern half of the view and lighter yellows in the southern corresponds to two land surfaces. The darker is a higher, flat land surface developed on horizontal Nama Sandstone’s, with rock surfaces widely coated with a dark manganese stain, typical of desert regions. This region is known as Namaqualand and borders the Namib Desert. Where rivers have cut down into this surface, the lighter underlying rock and soil colors show up.

Exploring experts' views and perspectives on the enhancement of Strategic Environmental Assessment in European small islands

Small islands have the attention of the international community because they are territories with unique features, and a pressing need for the enhancement of sustainability. Strategic Environmental Assessment (SEA) has characteristics that may promote the development and improvement of sustainability in these territories: (i) changing the mind-set, and the decision-making and institutional paradigm, (ii) facilitating cooperation and coordination between different stakeholders, and (iii) providing a framework for good governance and community empowerment. The scientific literature suggests that there may be a need for context-specific SEA in these territories. However, SEA studies often do not incorporate local contextual information, including intuitivemore » knowledge and sense of place. Therefore, there is a possible gap between what is found in the literature and what local communities think, including different stakeholders and experts. Hence, the main goal of this research was to gain an insight into the views and perspectives of small islands SEA experts about issues related to SEA in European small islands, including context-specific approaches, as well as the contribution of SEA for sustainability in these territories. To achieve the research aim, exploratory research using a questionnaire-based survey was designed, aimed at experts on SEA in European small islands. Findings showed regional cooperation networks may have a fundamental role when developing SEA-specific approaches in these territories. This is because SEA-specific approaches encourage a joint effort among islands within one region to improve SEA capacity-building, develop and share a baseline information system, and to share and exchange resources, overall. Also, guidelines are preferred among experts over more legal frameworks and regulations. Finally, the research showed that experts view SEA as a way to enhance sustainability in small islands. This study highlights the importance of

In many rural livelihoods in sub-Saharan Africa, crop productivity plays an important role since it links with food insecurity, which again is a major constraining factor in livelihood development. Sustainable livelihood development and land degradation are closely connected: lacking sustainability often results in land degradation, whereas the incidence of land degradation frequently frustrates sustainable development. Important forms of land degradation are soil erosion and nutrient depletion, both often being attributed to exhaustive land use practices and both having a direct and major impact on crop productivity. Application of nutrients is an important way to increase productivity. In our study area, central Tigray, development agents recommend the application of fertilizers at high rates in order to boost productivity and to deal with nutrient depletion. In the discussion about the use of fertilizers different perspectives can be taken, in which especially responses and nutrient balances are important issues, linking respectively with socio-economic and agro-ecological livelihood aspects. Ethiopian soils for example are, based on large scale nutrient balances, considered to be depleted, at field scale fertilizer responses are frequently disappointing and achieving sustainable nutrient balances at farm level seems difficult. At a temporal scale however, agricultural systems remained almost unchanged for over 2500 years, suggesting at least some degree of sustainability. With respect to productivity data resulting from on-farm experimentation with natural and artificial fertilizers in 26 sites, we took four perspectives, different in ownership and scale, on nutrient related land degradation and its assumed impact on crop productivity. Taking a farmer perspective we found no significant difference between responses to recommended and current farmer based practices. Taking a more scientific perspective highlighted that, based on the positive correlation between

While the HIV epidemic in South Africa had a later onset than epidemics in other southern African countries, prevalence grew rapidly during the 1990's when the country was going through socio-political changes with the end of Apartheid. South Africa currently has the largest number of people living with HIV in the world and the epidemic is dominated by a unique subtype, HIV-1 subtype C. This large epidemic is also characterized by high level of genetic diversity. We hypothesize that this diversity is due to multiple introductions of the virus during the period of change. In this paper, we apply novel phylogeographic methods to estimate the number of viral imports and exports from the start of the epidemic to the present. We assembled 11,289 unique subtype C pol sequences from southern Africa. These represent one of the largest sequence datasets ever analyzed in the region. Sequences were stratified based on country of sampling and levels of genetic diversity were estimated for each country. Sequences were aligned and a maximum-likelihood evolutionary tree was inferred. Least-Squares Dating was then used to obtain a dated phylogeny from which we estimated the number of introductions into and exports out of South Africa using parsimony-based ancestral location reconstructions. Our results identified 189 viral introductions into South Africa with the largest number of introductions attributed to Zambia (n=109), Botswana (n=32), Malawi (n=26) and Zimbabwe (n=13). South Africa also exported many viral lineages to its neighbours. The bulk viral imports and exports appear to have occurred between 1985 and 2000, coincident with the period of socio-political transition. The high level of subtype C genetic diversity in South Africa is related to multiple introductions of the virus to the country. While the number of viral imports and exports we identified was highly sensitive to the number of samples included from each country, they mostly clustered around the period of

Olaniran, Abimbola A

2013-12-01

Female genital mutilation (FGM) is an age-old practice that has since been linked with many health problems. This review aims to highlight some of the controversies trailing the relationship between FGM and HIV transmission in sub-Saharan Africa. A literature search was conducted on the subject matter. This was done using articles published in English while limiting the geographical coverage to sub-Saharan Africa. Three themes were noted. These themes include: Direct causal link between FGM and HIV transmission; indirect causal link between FGM and HIV transmission and a negative or no association between FGM and HIV transmission. While many of the arguments are within scientific reasoning, the researches supporting the views seem to lack the necessary objectivity. This study underscored the need for a more objective lens in viewing and conducting research on the relationship between FGM and HIV transmission in sub-Saharan Africa.

Reconsideration of Plant Morphological Traits: From a Structure-Based Perspective to a Function-Based Evolutionary Perspective

PubMed Central

Bai, Shu-Nong

2017-01-01

This opinion article proposes a novel alignment of traits in plant morphogenesis from a function-based evolutionary perspective. As a member species of the ecosystem on Earth, we human beings view our neighbor organisms from our own sensing system. We tend to distinguish forms and structures (i.e., “morphological traits”) mainly through vision. Traditionally, a plant was considered to be consisted of three parts, i.e., the shoot, the leaves, and the root. Based on such a “structure-based perspective,” evolutionary analyses or comparisons across species were made on particular parts or their derived structures. So far no conceptual framework has been established to incorporate the morphological traits of all three land plant phyta, i.e., bryophyta, pteridophyta and spermatophyta, for evolutionary developmental analysis. Using the tenets of the recently proposed concept of sexual reproduction cycle, the major morphological traits of land plants can be aligned into five categories from a function-based evolutionary perspective. From this perspective, and the resulting alignment, a new conceptual framework emerges, called “Plant Morphogenesis 123.” This framework views a plant as a colony of integrated plant developmental units that are each produced via one life cycle. This view provided an alternative perspective for evolutionary developmental investigation in plants. PMID:28360919

Heat Pump Drying of Fruits and Vegetables: Principles and Potentials for Sub-Saharan Africa

Fayose, Folasayo; Huan, Zhongjie

2016-01-01

Heat pump technology has been used for heating, ventilation, and air-conditioning in domestic and industrial sectors in most developed countries of the world including South Africa. However, heat pump drying (HPD) of fruits and vegetables has been largely unexploited in South Africa and by extension to the sub-Saharan African region. Although studies on heat pump drying started in South Africa several years ago, not much progress has been recorded to date. Many potential users view heat pump drying technology as fragile, slow, and high capital intensive when compared with conventional dryer. This paper tried to divulge the principles and potentials of heat pump drying technology and the conditions for its optimum use. Also, various methods of quantifying performances during heat pump drying as well as the quality of the dried products are highlighted. Necessary factors for maximizing the capacity and efficiency of a heat pump dryer were identified. Finally, the erroneous view that heat pump drying is not feasible economically in sub-Saharan Africa was clarified. PMID:26904668

With its vast expanses of sand, framed by mountain ranges and exposed rock, northwestern Africa makes a pretty picture when viewed from above. This image was acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. The Canary Islands can be seen on the left side of the image just off Africa's Atlantic shore. The light brown expanse running through the northern two thirds of the image is the Sahara Desert. The desert runs up against the dark brown Haut Atlas mountain range of Morocco in the northwest, the Atlantic Ocean to the west and the semi-arid (light brown pixels) Sahelian region in the South. The Sahara, however, isn't staying put. Since the 1960s, the desert has been expanding into the Sahelian region at a rate of up to 6 kilometers per year. In the 1980s this desert expansion, combined with over cultivation of the Sahel, caused a major famine across west Africa. Over the summer months, strong winds pick up sands from the Sahara and blow them across the Atlantic as far west as North America, causing air pollution in Miami and damaging coral reefs in the Bahamas and the Florida Keys. The white outlines on the map represent country borders. Starting at the top-most portion of the map and working clockwise, the countries shown are Morocco, Western Sahara, Mauritania, Senegal, Mali, Burkina Fasso, Nigeria, Mali (again), and Algeria.

Degrees and diplomas as well as certificates that are granted by universities and technikons in South Africa in scientific disciplines, such as forensic medicine, pharmacology, marine and veterinary sciences, environmental health, and occupational hygiene, include toxicology as one of the subjects in their overall syllabus. However, aspects of toxicology included in each of these courses are biased towards that particular subdiscipline and basic level of toxicology may be taught. Educational needs in toxicology in South Africa can be summarized as follows: (a) recognition of toxicology as a discipline in its own right at these tertiary education institutions and (b) creation of opportunities to study and obtain higher degrees in one or more of the many subdisciplines of toxicology. The results from a survey conducted on the toxicology syllabi offered at these tertiary education institutions are used to substantiate these needs.

Patients as consumers of health care in South Africa: the ethical and legal implications.

Rowe, Kirsten; Moodley, Keymanthri

2013-03-21

South Africa currently has a pluralistic health care system with separate public and private sectors. It is, however, moving towards a socialised model with the introduction of National Health Insurance. The South African legislative environment has changed recently with the promulgation of the Consumer Protection Act and proposed amendments to the National Health Act. Patients can now be viewed as consumers from a legal perspective. This has various implications for health care systems, health care providers and the doctor-patient relationship. Calling a recipient of health care a 'consumer' as opposed to a 'patient' has distinct connotations and may result in differential behaviour. Labels reflect the ideals of the context in which they are used. Various models of the doctor-patient relationship exist and different metaphors have been used to describe it. Increasingly there are third parties involved within the doctor-patient relationship making it more difficult for the doctor to play the fiduciary role. In certain parts of the world, there has been a shift from a traditional paternalistic model to a consumerist model. The ethical implications of the commodification of health care are complex. As health care becomes a 'product' supplied by the health care 'provider', there is the risk that doctors will replace professional ethics with those of the marketplace. Health care is a universal human need and cannot be considered a mere commodity. In modern medical ethics, great emphasis is placed on the principle of respect for patient autonomy. Patients are now the ultimate decision-makers. The new Consumer Protection Act in South Africa applies to consumers and patients alike. It enforces strict liability for harm caused by goods and services. Everyone in the supply chain, including the doctor, can be held jointly and severally liable. This may lead to enormous challenges in health care delivery. Viewing patients as consumers may be detrimental to the doctor

Perspectives of policy-makers and stakeholders about health care waste management in community-based care in South Africa: a qualitative study.

PubMed

Hangulu, Lydia; Akintola, Olagoke

2017-04-19

In South Africa, a new primary health care (PHC) re-engineering initiative aims to scale up the provision of community-based care (CBC). A central element in this initiative is the use of outreach teams comprising nurses and community health workers to provide care to the largely poor and marginalised communities across the country. The provision of care will inevitably lead to an increase in the amount of health care waste (HCW) generated in homes and suggests the need to pay more attention to the HCW that emanates from homes where there is care of a patient. CBC in South Africa is guided by the home-based care policy. However, this policy does not deal with issues about how HCW should be managed in CBC. This study sought to explore health care waste management (HCWM) in CBC in South Africa from the policy-makers' and stakeholders' perspective. Semi-structured interviews were conducted with 9 policy-makers and 21 stakeholders working in 29 communities in Durban, South Africa. Interviews were conducted in English; were guided by an interview guide with open-ended questions. Data was analysed thematically. The Durban Solid waste (DSW) unit of the eThekwini municipality is responsible for overseeing all waste management programmes in communities. Lack of segregation of waste and illegal dumping of waste were the main barriers to proper management practices of HCW at household level while at the municipal level, corrupt tender processes and inadequate funding for waste management programmes were identified as the main barriers. In order to address these issues, all the policy-makers and stakeholders have taken steps to collaborate and develop education awareness programmes. They also liaise with various government offices to provide resources aimed at waste management programmes. HCW is generated in CBC and it is poorly managed and treated as domestic waste. With the rollout of the new primary health care model, there is a greater need to consider HCWM in CBC. There

Background Investments in faculty exchanges to build physician workforce capacity are increasing. Little attention has been paid to the expectations of host institution faculty and trainees. This prospective qualitative research study explored faculty and resident perspectives about guest faculty in paediatric departments in East Africa, asking (1) What are the benefits and challenges of hosting guest faculty, (2) What factors influence the effectiveness of faculty visits and (3) How do host institutions prepare for faculty visits? Methods We recruited 36 faculty members and residents from among four paediatric departments in East Africa to participate in semistructured interviews which were audio recorded and transcribed. Data were qualitatively analysed using principles of open coding and thematic analysis. We achieved saturation of themes. Results Benefits of faculty visits varied based on the size and needs of host institutions. Emergent themes included the importance of guest faculty time commitment, and mutual preparation to ensure that visit goals and scheduling met host needs. We documented conflicts that developed around guest emotional responses and ethical approaches to clinical resource limitations, which some hosts tried to prepare for and mitigate. Imbalance in resources led to power differentials; some hosts sought partnerships to re-establish control over the process of having guests. Conclusions We identified that guest faculty can assist paediatric institutions in building capacity; however, effective visits require: (1) mutually agreed on goals with appropriate scheduling, visit length and commitment to ensure that the visits meet the host's needs, (2) careful selection and preparation of guest faculty to meet the host's goals, (3) emotional preparation by prospective guests along with host orientation to clinical work in the host's setting and (4) attention to funding sources for the visit and mitigation of resulting power differentials.

Non-methane volatile organic compounds in Africa: A view from space

NASA Astrophysics Data System (ADS)

Marais, Eloise Ann

Isoprene emissions affect human health, air quality, and the oxidative capacity of the atmosphere. Globally anthropogenic non-methane volatile organic compounds (NMVOC) emissions are lower than that of isoprene, but local hotspots are hazardous to human health and air quality. In Africa the tropics are a large source of isoprene, while Nigeria appears as a large contributor to regional anthropogenic NMVOC emissions. I make extensive use of space-based formaldehyde (HCHO) observations from the Ozone Monitoring Instrument (OMI) and the chemical transport model (CTM) GEOS-Chem to estimate and examine seasonality of isoprene emissions across Africa, and identify sources and air quality consequences of anthropogenic NMVOC emissions in Nigeria. To estimate isoprene emissions I first developed a filtering scheme to remove (1) contamination from biomass burning and anthropogenic influences; and (2) displacement of HCHO from the isoprene emission source diagnosed with the GEOS-Chem CTM. Conversion to isoprene emissions is with NOx-dependent GEOS-Chem HCHO yields, obtained as the local sensitivity S of the HCHO column ΩHCHO to a perturbation Delta in isoprene emissions EISOP (S = DeltaΩHCHO/DeltaE ISOP). The error in OMI-derived isoprene emissions is 40% at low levels of NOx and 40-90% under high-NOx conditions and is reduced by spatial and temporal averaging to the extent that errors are random. Weak isoprene emission seasonality in equatorial forests is driven predominantly by temperature, while large seasonality in northern and southern savannas is driven by temperature and leaf area index. The largest contribution of African isoprene emissions to surface ozone and particulate matter, determined with GEOS-Chem, of 8 ppbv and 1.5 μg m-3, respectively, is over West Africa. The OMI HCHO data feature a large enhancement over Nigeria that is due to anthropogenic NMVOC emissions. With the OMI HCHO data, coincident satellite observations of atmospheric composition, aircraft

Health and wealth in Uzbekistan and sub-Saharan Africa in comparative perspective.

Hohmann, Sophie; Garenne, Michel

2010-12-01

The study investigates the magnitude of differences in child and adult mortality by wealth in Uzbekistan, a former soviet country of Central Asia, and compares it with similar indicators from sub-Saharan Africa. Data were derived from Demographic and Health Surveys. An "Absolute Wealth Index" was built from data on goods owned by households and quality of housing, and scaled from 0 to 12. Wealth was distributed evenly in Uzbekistan, with a symmetric distribution around a mean of 5.5 modern goods. In sub-Saharan Africa, on the contrary, the wealth distribution had a lower mean (2.5) and was highly skewed towards the left, revealing a high proportion of very poor people. Adult and child mortality levels were lower in Uzbekistan. Despite these major differences, the relationships between mortality indicators and the wealth index were similar in the two cases. The magnitude of mortality differentials by wealth was of the same order in both cases, with gradients ranging from 2.5 to 1 for child mortality and 1.5 to 1 for adult mortality (poorest versus richest). However, mortality levels remained lower in Uzbekistan than in sub-Saharan Africa at the same level of wealth for both children and adults. A similar relationship was found between nutritional status and wealth index in both cases. On the contrary, there were no differences by wealth in use of health services and level of education in Uzbekistan, whereas wealth gradients were steep for the same variables in sub-Saharan Africa. The study suggests that mortality differentials were primarily due to nutritional status, and not to access and use of health services or to education. The discussion focuses on health and social policies during the colonial and post-colonial period that have produced these patterns. Copyright © 2010 Elsevier B.V. All rights reserved.

2013-04-01

Relatively little research has been conducted on religion and suicide in Africa, yet religion has a lot of influence on people's way of life in Africa. To study religious views on suicide among the Baganda, Uganda, we used grounded theory and discourse analysis on a total of 28 focus groups and 30 key informant interviews. Suicide is largely seen as a breach of God's doctrine life is sacred, God's commandment thou shall not kill, and God's rule of agape. The study also focuses on the consequences of breaching God's divine providence: punishment from God and the Church. Religion still has a lot of influence on people's views on suicide in Uganda despite the challenges highlighted in the study. A recommendation from these results is that suicide prevention should cater to divergent views on religion and suicide. More qualitative research should be conducted in this area to facilitate theoretical comparison with this study.

Scrutinizing impacts of conspiracy theories on readers' political views: a rational choice perspective on anti-semitic rhetoric in Turkey.

PubMed

Nefes, Turkay Salim

2015-09-01

Although conspiracy theories have been politically significant throughout history, only a few empirical studies have been about their influence on readers' views. Combining a rational choice approach with a content analysis of an anti-Semitic best-selling conspiracy theory book series in Turkey - the Efendi series - and semi-structured interviews with its readers, this paper reveals the effects of the conspiracy theories on readers' political perspectives. The findings suggest that whereas the rightists are reactive to the Jewish origins of the Dönmes, the leftists oppose the Dönmes as dominant bourgeois figures. This paper concludes that left- and right-wing adherents use the conspiratorial accounts in line with their political views and ontological insecurities. It expands the existing academic literature, which conceptualizes conspiracy theories either as paranoid delusions or as neutral, rational narratives, by showing that they can be both. © London School of Economics and Political Science 2015.

Perspective image comprehension depends on both visual and proprioceptive information.

2014-11-01

Proprioceptive information can supplement visual information in the comprehension of ambiguous perspective images. The importance of proprioceptive information in unambiguous perspective image comprehension is untested, however. We explored the role of proprioception in perspective image comprehension using three experiments in which participants took or imagined taking an upward- or downward-oriented posture and then made judgments about images viewed from below or viewed from above. Participants were faster and more accurate in their judgments when their actual or simulated posture was consistent with the posture implied by the perspective of the image they were judging. These results support a role for proprioception in the comprehension of unambiguous perspective images as well as ambiguous perspective images.

Migration and Development: A Theoretical Perspective 1

PubMed Central

De Haas, Hein

2010-01-01

The debate on migration and development has swung back and forth like a pendulum, from developmentalist optimism in the 1950s and 1960s, to neo‐Marxist pessimism over the 1970s and 1980s, towards more optimistic views in the 1990s and 2000s. This paper argues how such discursive shifts in the migration and development debate should be primarily seen as part of more general paradigm shifts in social and development theory. However, the classical opposition between pessimistic and optimistic views is challenged by empirical evidence pointing to the heterogeneity of migration impacts. By integrating and amending insights from the new economics of labor migration, livelihood perspectives in development studies and transnational perspectives in migration studies – which share several though as yet unobserved conceptual parallels – this paper elaborates the contours of a conceptual framework that simultaneously integrates agency and structure perspectives and is therefore able to account for the heterogeneous nature of migration‐development interactions. The resulting perspective reveals the naivety of recent views celebrating migration as self‐help development “from below”. These views are largely ideologically driven and shift the attention away from structural constraints and the vital role of states in shaping favorable conditions for positive development impacts of migration to occur.

There is limited information about the challenges of cancer management and attempts at improving outcomes in Africa. Even though South and North Africa are better resourceds to tackle the burden of breast cancer, similar poor prognostic factors are common to all countries. The five-year overall Survival rate for breast cancer patients does not exceed 60% for any low and middle-income country (LMIC) in Africa. In spite of the gains achieved over the past decade, certain characteristics remain the same such as limited availability of breast conservation therapies, inadequate access to drugs, few oncology specialists and adherence to harmful socio-cultural practices. This review on managing breast cancer in Africa is authored by African oncologists who practice or collaborate in Africa and with hands-on experience with the realities. A search was performed via electronic databases from 1999 to 2016. (PubMed/Medline, African Journals Online) for all literature in English or translated into English, covering the terms "breast cancer in Africa and developing countries". One hundred ninety were deemed appropriate. Breast tumors are diagnosed at earlier ages and later stages than in highincome countries. There is a higher prevalence of triple-negative cancers. The limitations of poor nursing care and surgery, inadequate access to radiotherapy, poor availability of basic and modern systemic therapies translate into lower survival rate. Positive strides in breast cancer management in Africa include increased adaptation of treatment guidelines, improved pathology services including immuno-histochemistry, expansion and upgrading of radiotherapy equipment across the continent in addition to more research opportunities. This review is an update of the management of breast cancer in Africa, taking a look at the epidemiology, pathology, management resources, outcomes, research and limitations in Africa from the perspective of oncologists with local experience.

“Without a mother”: caregivers and community members’ views about the impacts of maternal mortality on families in KwaZulu-Natal, South Africa

PubMed Central

2015-01-01

Background Maternal mortality in South Africa is high and a cause for concern especially because the bulk of deaths from maternal causes are preventable. One of the proposed reasons for persistently high maternal mortality is HIV which causes death both indirectly and directly. While there is some evidence for the impact of maternal death on children and families in South Africa, few studies have explored the impacts of maternal mortality on the well-being of the surviving infants, older children and family. This study provides qualitative insight into the consequences of maternal mortality for child and family well-being throughout the life-course. Methods This qualitative study was conducted in rural and peri-urban communities in Vulindlela, KwaZulu-Natal. The sample included 22 families directly affected by maternal mortality, 15 community stakeholders and 7 community focus group discussions. These provided unique and diverse perspectives about the causes, experiences and impacts of maternal mortality. Results and discussion Children left behind were primarily cared for by female family members, even where a father was alive and involved. The financial burden for care and children’s basic needs were largely met through government grants (direct and indirectly targeted at children) and/or through an obligation for the father or his family to assist. The repercussions of losing a mother were felt more by older children for whom it was harder for caregivers to provide educational supervision and emotional or psychological support. Respondents expressed concerns about adolescent’s educational attainment, general behaviour and particularly girl’s sexual risk. Conclusion These results illuminate the high costs to surviving children and their families of failing to reduce maternal mortality in South Africa. Ensuring social protection and community support is important for remaining children and families. Additional qualitative evidence is needed to explore

Three dimensional perspective view of Mammoth Mountain, California

NASA Image and Video Library

1994-04-17

STS059-S-084 (17 April 1994) --- This is a three-dimensional perspective of Mammoth Mountain, California. This view was constructed by overlaying a SIR-C radar image on a U.S. Geological Survey digital elevation map. Vertical exaggeration is 2x. The image is centered at 37.6 degrees north, 119.0 degrees west. It was acquired from the Spaceborne Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR) onboard the Space Shuttle Endeavour on its 67th orbit, April 13, 1994. In this color representation, red is C-Band HV-polarization, green is C-Band VV-polarization and blue is the ratio of C-Band VV to C-Band HV. Blue areas are smooth and yellow areas are rock outcrops with varying amounts of snow and vegetation. Crowley Lake is in the foreground and Highway 395 crosses in the middle of the image. Mammoth Mountain is shown in the upper right. SIR-C/X-SAR is part of NASA's Mission to Planet Earth (MTPE). SIR-C/X-SAR radars illuminate Earth with microwaves allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-Band (24 cm), C-Band (6 cm), and X-Band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory (JPL). X-SAR was developed by the Dornire and Alenia Spazio Companies for the German Space Agency, Deutsche Agentur fuer Raumfahrtangelegenheiten (DARA), and the Italian Space Agency, Agenzia Spaziale Italiana (ASI).

Access to Schooling in a Post-Apartheid South Africa: Linking Concepts to Context

NASA Astrophysics Data System (ADS)

Fataar, Aslam

1997-07-01

This paper focuses on the policy issue of expanding schooling in a post-apartheid South Africa. The Project of placing about two million children of school-going age in school is viewed as central to the rebuilding of South Africa. The paper argues that this project should be located within the peculiar history of this country's educational underdevelopment. Challenging the constraining influence of the New Right context should be central in conceptualising the provision of expanded school access. Access policy should be based on a notion of educational development that is linked to the overall socioeconomic development of this society. The view is promoted in this paper that a policy of quantitative expansion of schooling should not ignore the quality of such schooling.

Discrepancies in Data Reporting for Rabies, Africa

PubMed Central

2013-01-01

Human rabies is an ancient disease but in modern times has primarily been associated with dog rabies–endemic countries of Asia and Africa. From an African perspective, the inevitable and tragic consequences of rabies require serious reflection of the factors that continue to drive its neglect. Established as a major disease only after multiple introductions during the colonial era, rabies continues to spread into new reservoirs and territories in Africa. However, analysis of reported data identified major discrepancies that are indicators of poor surveillance, reporting, and cooperation among national, international, and global authorities. Ultimately, the absence of reliable and sustained data compromises the priority given to the control of rabies. Appropriate actions and changes, in accordance to the One Health philosophy and including aspects such as synchronized, shared, and unified global rabies data reporting, will not only be necessary, but also should be feasible.

more active part of the international geoscience information community. The programme for the GIRAF 2009 workshop was designed to explore each of these aspects to improve the way geoscience information contributes to improve the health and prosperity of the people in Africa. The Programme The aim of the week wasto better understand the reality of the status of geoscience information management, delivery, and systems from the perspective of the practitioners across Africa. To do that, in addition to VIP welcome speeches and presentations from across the continent, the programme included two sets of breakout sessions allowing more detailed discussion of specific issues, and each day, a novel "Question of the day", where individual feedback was sought on three pointed questions. These exercises ensured that everyone was able to contribute their views and experiences. The conclusion - a 15 point GIRAF 2009 Strategy and Agreement The results were intense discussion of the issues which the participants felt were key to developing and improving the way geoscience information could be managed and delivered in Africa. The very tangible outcome of a hardworking but fruitful week was the unanimous endorsement of a series of fifteen practical recommendations - the GIRAF Strategy and Agreement. Our week together provided new and valuable experience and new contacts, networks and friendships and most importantly the base for a sustainable initiative to improve the way geoscience information will be managed and delivered in Africa. We now look forward and are working on to taking those important recommendations forward.

Ecosystem variability and early human habitats in eastern Africa.

PubMed

Magill, Clayton R; Ashley, Gail M; Freeman, Katherine H

2013-01-22

The role of savannas during the course of early human evolution has been debated for nearly a century, in part because of difficulties in characterizing local ecosystems from fossil and sediment records. Here, we present high-resolution lipid biomarker and isotopic signatures for organic matter preserved in lake sediments at Olduvai Gorge during a key juncture in human evolution about 2.0 Ma--the emergence and dispersal of Homo erectus (sensu lato). Using published data for modern plants and soils, we construct a framework for ecological interpretations of stable carbon-isotope compositions (expressed as δ(13)C values) of lipid biomarkers from ancient plants. Within this framework, δ(13)C values for sedimentary leaf lipids and total organic carbon from Olduvai Gorge indicate recurrent ecosystem variations, where open C(4) grasslands abruptly transitioned to closed C(3) forests within several hundreds to thousands of years. Carbon-isotopic signatures correlate most strongly with Earth's orbital geometry (precession), and tropical sea-surface temperatures are significant secondary predictors in partial regression analyses. The scale and pace of repeated ecosystem variations at Olduvai Gorge contrast with long-held views of directional or stepwise aridification and grassland expansion in eastern Africa during the early Pleistocene and provide a local perspective on environmental hypotheses of human evolution.

A 3-dimensional echocardiographic view of the mitral valve, called the "en face" or "surgical view," presents a view of the mitral valve similar to that seen by the surgeon from a left atrial perspective. Although the anatomical landmarks of this view are well defined, no comprehensive echocardiographic definition has been presented. After reviewing the literature, we provide a definition of the left atrial and left ventricular en face views of the mitral valve. Techniques used to acquire this view are also discussed.

SRTM Perspective View with Landsat Overlay: Santa Paula, and Santa Clara River Valley, California

NASA Technical Reports Server (NTRS)

2000-01-01

Rectangular fields of the agriculturally rich Santa Clara River Valley are visible in this perspective view generated using data from the Shuttle Radar Topography Mission and an enhanced Landsat image. The Santa Clara River, which lends its name to this valley, flows from headwaters near Acton, California, 160 km (100 miles) to the Pacific Ocean, and is one of only two natural river systems remaining in southern California. In the foreground of this image, the largely dry riverbed can be seen as a bright feature as it winds its way along the base of South Mountain. The bright region at the right end of this portion of the valley is the city of Santa Paula, California. Founded in 1902, this small, picturesque town at the geographic center of Ventura County is referred to as the 'Citrus Capital of the World.' The city is surrounded by orange, lemon, and avocado groves and is a major distribution point for citrus fruits in the United States. The bright, linear feature in the center of the valley is State Highway 126, the valley's 'main drag.' For visualization purposes, topographic heights displayed in this image are exaggerated two times. Colors, from Landsat data, approximate natural color.

The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of Earth's land surface. To collect the 3-D SRTM data, engineers added a mast 60 meters (about 200 feet)long, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense, and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory

Bluetongue: a historical and epidemiological perspective with the emphasis on South Africa

PubMed Central

2012-01-01

Bluetongue (BT) is a non-contagious, infectious, arthropod transmitted viral disease of domestic and wild ruminants that is caused by the bluetongue virus (BTV), the prototype member of the Orbivirus genus in the family Reoviridae. Bluetongue was first described in South Africa, where it has probably been endemic in wild ruminants since antiquity. Since its discovery BT has had a major impact on sheep breeders in the country and has therefore been a key focus of research at the Onderstepoort Veterinary Research Institute in Pretoria, South Africa. Several key discoveries were made at this Institute, including the demonstration that the aetiological agent of BT was a dsRNA virus that is transmitted by Culicoides midges and that multiple BTV serotypes circulate in nature. It is currently recognized that BT is endemic throughout most of South Africa and 22 of the 26 known serotypes have been detected in the region. Multiple serotypes circulate each vector season with the occurrence of different serotypes depending largely on herd-immunity. Indigenous sheep breeds, cattle and wild ruminants are frequently infected but rarely demonstrate clinical signs, whereas improved European sheep breeds are most susceptible. The immunization of susceptible sheep remains the most effective and practical control measure against BT. In order to protect sheep against multiple circulating serotypes, three pentavalent attenuated vaccines have been developed. Despite the proven efficacy of these vaccines in protecting sheep against the disease, several disadvantages are associated with their use in the field. PMID:22973992

South Africa is a major hub of HIV prevention trials, with plans for a licensure trial to start in 2015. The appropriate standards of care and of prevention in HIV vaccine trials are complex and debated issues and ethical guidelines offer some direction. However, there has been limited empirical exploration of South African stakeholders' perspectives on ethical guidance related to prevention and care in HIV vaccine trials. Site staff, Community Advisory Board members and Research Ethics Committee members involved with current HIV vaccine trials in South Africa were invited to participate in an exploration of their views. A questionnaire listed 10 care and 10 prevention recommendations drawn from two widely available sets of ethical guidelines for biomedical HIV prevention trials. Respondents (n = 98) rated each recommendation on five dimensions: "Familiarity with", "Ease of Understanding", "Ease of Implementing", "Perceived Protection", and "Agreement with" each ethical recommendation. The ratings were used to describe stakeholder perspectives on dimensions for each recommendation. Dimension ratings were averaged across the five dimensions and used as an indication of overall merit for each recommendation. Differences were explored across dimensions, between care-oriented and prevention-oriented recommendations, and between stakeholder groups. Both care and prevention recommendations were rated highly overall, with median ratings well above the scale midpoint. In general, informed consent recommendations were most positively rated. Care-related recommendations were rated significantly more positively than prevention-related recommendations, with the five lowest-rated recommendations being prevention-related. The most problematic dimension across all recommendations was "Ease of Implementing," and the least problematic was "Agreement with," suggesting the most pressing stakeholder concerns are practical rather than theoretical; that is, respondents agree with

The banking of biological samples raises a number of ethical issues in relation to the storage, export and re-use of samples. Whilst there is a growing body of literature exploring participant perspectives in North America and Europe, hardly any studies have been reported in Africa. This is problematic in particular in light of the growing amount of research taking place in Africa, and with the rise of biobanking practices also on the African continent. In order to investigate the perspectives of African research participants, we conducted a study with research participants in a TB study in the Western Cape, South Africa. Semi-structured interviews were conducted using an interview guide which drew on the most prominent themes expressed in current literature on sample storage, re-use and exportation. Interviews were conducted in Afrikaans and subsequently translated into English by the same interviewer. Interviews were transcribed verbatim and analysed qualitatively. The results of our study indicate that the majority of participants were supportive of giving one-time consent to the storage and re-use of their samples. The concept of research being for a "good cause" was a central prerequisite. Additionally, a significant minority requested that they be re-contacted if a future use was not stipulated on the original consent. There was also considerable variation in how participants understood the concept of a 'good cause', with participants describing three distinct categories of research, of which two were generally thought to constitute 'good cause' research. Research that was for-profit was considered to fall outside the spectrum of 'good cause' research. Participants displayed confidence in the abilities of the researchers to make future decisions regarding sample use, but seemed unaware of the role of ethics committees in either this process or more generally. Participants expressed a wide and complex range of views about issues of sample storage and re

How Can the Operating Environment for Nutrition Research Be Improved in Sub-Saharan Africa? The Views of African Researchers

Optimal nutrition is critical for human development and economic growth. Sub-Saharan Africa is facing high levels of food insecurity and only few sub-Saharan African countries are on track to eradicate extreme poverty and hunger by 2015. Effective research capacity is crucial for addressing emerging challenges and designing appropriate mitigation strategies in sub-Saharan Africa. A clear understanding of the operating environment for nutrition research in sub-Saharan Africa is a much needed prerequisite. We collected data on the barriers and requirements for conducting nutrition research in sub-Saharan Africa through semi-structured interviews with 144 participants involved in nutrition research in 35 countries in sub-Saharan Africa. A total of 133 interviews were retained for coding. The main barriers identified for effective nutrition research were the lack of funding due to poor recognition by policymakers of the importance of nutrition research and under-utilisation of research findings for developing policy, as well as an absence of research priority setting from within Africa. Current research topics were perceived to be mainly determined by funding bodies from outside Africa. Nutrition researchers argued for more commitment from policymakers at national level. The low capacity for nutrition research was mainly seen as a consequence of insufficient numbers of nutrition researchers, limited skills and a poor research infrastructure. In conclusion, African nutrition researchers argued how research priorities need to be identified by African stakeholders, accompanied by consensus building to enable creating a problem-driven national research agenda. In addition, it was considered necessary to promote interactions among researchers, and between researchers and policymakers. Multidisciplinary research and international and cross-African collaboration were seen as crucial to build capacity in sub-Saharan nutrition research. PMID:23776663

Three dimensional perspective view of portion of western Galapagos Islands

NASA Image and Video Library

1994-04-18

STS059-S-085 (18 April 1994) --- This is a three-dimensional perspective view of part of Isla Isabela in the western Galapagos Islands. It was taken by the L-Band radar in HH polarization from the Spaceborne Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR) on the 40th orbit of the Space Shuttle Endeavour. This view was constructed by overlaying a SIR-C radar image on a U.S. Geological Survey digital elevation map. The image is centered at about .5 degrees south latitude and 91 degrees west longitude, and covers an area of 75 by 60 kilometers. The radar incidence angle at the center of the image is about 20 degrees. The western Galapagos Islands, which lie about 1200 kilometers west of Ecuador in the eastern Pacific, have six active volcanoes similar to the volcanoes found in Hawaii. Since the time of Charles Darwin's visit to the area in 1835, there have been over 60 recorded eruptions on these volcanoes. This SIR-C/X-SAR image of Alcedo and Sierra Negra volcanoes shows the rougher lava flows as bright features, while ash deposits and smooth pahoehoe lava flows appear dark. The Galapagos Islands are one of the SIR-C/X-SAR supersites and data of this area will be taken several times during the flight to allow scientists to conduct topographic change studies and to search for different lava flow types, ash deposits and fault lines. SIR-C/X-SAR is part of NASA's Mission to Planet Earth (MTPE). SIR-C/X-SAR radars illuminate Earth with microwaves allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-Band (24 cm), C-Band (6 cm), and X-Band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes

The Relations of Family Members’ Unique and Shared Perspectives of Family Dysfunction to Dyad Adjustment

Jager, Justin; Yuen, Cynthia X.; Bornstein, Marc H.; Putnick, Diane L.; Hendricks, Charlene

2017-01-01

Among a community sample of families (N = 128), this study examined how family members’ shared and unique perspectives of family dysfunction relate to dyad members’ shared views of dyad adjustment within adolescent-mother, adolescent-father, and mother-father dyads. Independent of a family’s family perspective (shared perspective of family dysfunction), the adolescent’s unique perspective was associated with lower security and higher conflict with both mother and father, the father’s unique perspective was associated with lower security and higher conflict with the adolescent as well as lower marital quality with mother, and the mother unique perspective was associated with lower marital quality with the father. Moreover, for adolescent-parent dyads, compared to the parent unique perspective, the adolescent unique perspective was more strongly associated with dyad adjustment. These findings indicate that both shared and unique views of the family system – the adolescent’s unique view in particular - independently relate to the health of family subsystems. They also suggest that research as well as therapeutic interventions that focus on just the shared view of the family may miss important elements of family dysfunction. PMID:24884682

Road Maintenance in Africa: Approaches and Perspectives

NASA Astrophysics Data System (ADS)

M, Mostafa Hassan

2018-06-01

In Africa, roads are the dominant mode of passenger and freight transport, for which the need is growing rapidly. It is noticeable that most of the African countries do not do enough to ensure the sustainability of road infrastructure as it has been widely reported that roads are affected, to varying degrees, by premature deterioration. Most of the African countries have adopted institutional reforms, notably entailing the creation of road funds and road agencies, and made significant progress on road maintenance. However, many challenges remain to be addressed in all of them to ensure appropriate maintenance. Although spending on road maintenance has increased over time in all African countries it remains insufficient to cover the needs. Poorly maintained roads constrain mobility, significantly raise vehicle operating costs, increase accident rates and their associated human and property costs, and aggravate isolation, poverty, poor health, and illiteracy in rural communities. This paper focuses, in particular, on road maintenance in some African countries considering types of road maintenance and the different approaches aiming at a comparison to reflect on similarities and differences.

Day-to-day care: the interplay of CNAs' views of residents & nursing home environments.

PubMed

Fisher, Lucy Takesue; Wallhagen, Margaret I

2008-11-01

This qualitative study identified certified nursing assistants' (CNAs') perspectives of nursing home residents and how these perspectives translate into care practices. Data included observations of and interviews with 27 CNAs in three dissimilar nursing homes. All participants were people of color, and all but 3 were immigrants. CNAs constructed three views of residents: as fictive kin, as a commodity, and as an autonomous person. Although individual CNAs held one primary view of residents in general, select residents were viewed from an alternative perspective, resulting in variations in care practices. These findings suggest that such distinctions, in tandem with structural, organizational, and cultural differences in nursing homes, present opportunities for nursing leadership to affect the visible, everyday practice of nursing CNAs. To target interventions, further research is needed on how CNAs come to differentially view residents and how these differences influence CNAs' care relationships with residents.

The heart of Africa: succeeding against the odds.

Sliwa, Karen

South Africa and other areas of sub-Saharan Africa have in the past 20 years undergone rapid demographical changes, largely due to urbanisation and changes in lifestyle. This rapid change has led to a marked increase in specific cardiac conditions, such as hypertensive heart disease and coronary artery disease (with the highest prevalence in the middle-aged population), in conjunction with a range of other heart diseases, which are historically common in Africa-eg, rheumatic heart disease, cardiomyopathies, and unoperated congenital heart disease. The short supply of well-equipped screening facilities, late diagnosis, and inadequate care at primary, secondary, and tertiary levels have led to a large burden of patients with poorly treated heart failure. Excellent progress has been made in the understanding of the epidemiology, sociodemographical factors, effect of urbanisation, and pathophysiology of cardiac conditions, such as peripartum cardiomyopathy, rheumatic heart disease, and tuberculous pericarditis, which are common in sub-Saharan Africa. This progress has been achieved largely through several studies, such as the Heart of Soweto, THESUS, REMEDY, BA-HEF, Abeokuta-HF, and the PAPUCO studies. Studies on the suitable therapeutic management of several heart conditions have also been done or are underway. In this Lecture, I provide a personal perspective on the evolving burden of cardiac disease, as witnessed since my appointment at Chris Hani Baragwanath Hospital, in Soweto, South Africa, in 1992, which was also the year that the referendum to end apartheid in South Africa was held. Subsequently, a network of cardiologists was formed under the umbrella of the Heart of Africa Studies and the Pan African Cardiac Society. Furthermore, I summarise the major gaps in the health-care system dealing with the colliding epidemic of communicable and non-communicable heart diseases, including cardiac diseases common in peripartum women. I also touch on the fantastic

Methods for systematic reviews are well developed for trials, but not for non-experimental or qualitative research. This paper describes the methods developed for reviewing research on people's perspectives and experiences ("views" studies) alongside trials within a series of reviews on young people's mental health, physical activity, and healthy eating. Reports of views studies were difficult to locate; could not easily be classified as "qualitative" or "quantitative"; and often failed to meet seven basic methodological reporting standards used in a newly developed quality assessment tool. Synthesising views studies required the adaptation of qualitative analysis techniques. The benefits of bringing together views studies in a systematic way included gaining a greater breadth of perspectives and a deeper understanding of public health issues from the point of view of those targeted by interventions. A systematic approach also aided reflection on study methods that may distort, misrepresent, or fail to pick up people's views. This methodology is likely to create greater opportunities for people's own perspectives and experiences to inform policies to promote their health.

Background Many low-income and middle-income countries globally are now pursuing ambitious plans for universal primary care, but are failing to deliver adequate care quality because of intractable human resource problems. Aim To understand why migrant nurses and doctors from sub-Saharan Africa did not wish to take up available posts in primary and first-contact care in their home countries. Design and setting Qualitative study of migrant health workers to Europe (UK, Belgium, and Austria) or southern Africa (Botswana and South Africa) from sub-Saharan Africa. Method Semi-structured interviews with 66 health workers (24 nurses and 42 doctors) from 18 countries between July 2011 and April 2012. Transcripts were analysed thematically using a framework approach. Results The reasons given for choosing not to work in primary care were grouped into three main analytic streams: poor working environment, difficult living experiences, and poor career path. Responders described a lack of basic medicines and equipment, an unmanageable workload, and lack of professional support. Many had concerns about personal security, living conditions (such as education for children), and poor income. Primary care was seen as lower status than hospital medicine, with lack of specialist training opportunities and more exposure to corruption. Conclusions Clinicians are reluctant to work in the conditions they currently experience in primary care in sub-Saharan Africa and these conditions tend to get worse as poverty and need for primary care increases. This inverse primary care law undermines achievement of universal health coverage. Policy experience from countries outside Africa shows that it is not immutable. PMID:24868069

SRTM Perspective View with Landsat Overlay: Ventura, and Lake Casitas, California

NASA Technical Reports Server (NTRS)

2000-01-01

Ventura, California is one of this state's oldest cities. Officially known as San Buenaventura, it was established in 1782 with the founding of the Mission San Buenaventura, the ninth of the 21 Spanish missions founded in California. In this perspective view generated from SRTM elevation data, the city can be seen occupying the shore of the Pacific Ocean and the nearby foothills. Lake Casitas, a reservoir and popular recreation area, is the dark blue feature in the center of the image. Holding back the 313,000 megaliter (254,000 acre-feet) storage capacity of the reservoir and visible as a very bright feature foreground of the lake, is the Casitas Dam, a 102-meter(334-foot) Earth fill dam. The reservoir and dam were built between 1956 and 1959 for the Federal Bureau of Reclamation's Ventura River Project. In addition to recreational use, Lake Casitas provides irrigation, municipal and industrial water to urban and suburban areas in Ventura County. For visualization purposes, topographic heights displayed in this image are exaggerated two times.

The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of Earth's land surface. To collect the 3-D SRTM data, engineers added a mast 60 meters (about 200 feet)long, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense, and the German and Italian space agencies.

The First Modern Human Dispersals across Africa

2013-01-01

The emergence of more refined chronologies for climate change and archaeology in prehistoric Africa, and for the evolution of human mitochondrial DNA (mtDNA), now make it feasible to test more sophisticated models of early modern human dispersals suggested by mtDNA distributions. Here we have generated 42 novel whole-mtDNA genomes belonging to haplogroup L0, the most divergent clade in the maternal line of descent, and analysed them alongside the growing database of African lineages belonging to L0’s sister clade, L1’6. We propose that the last common ancestor of modern human mtDNAs (carried by “mitochondrial Eve”) possibly arose in central Africa ~180 ka, at a time of low population size. By ~130 ka two distinct groups of anatomically modern humans co-existed in Africa: broadly, the ancestors of many modern-day Khoe and San populations in the south and a second central/eastern African group that includes the ancestors of most extant worldwide populations. Early modern human dispersals correlate with climate changes, particularly the tropical African “megadroughts” of MIS 5 (marine isotope stage 5, 135–75 ka) which paradoxically may have facilitated expansions in central and eastern Africa, ultimately triggering the dispersal out of Africa of people carrying haplogroup L3 ~60 ka. Two south to east migrations are discernible within haplogroup LO. One, between 120 and 75 ka, represents the first unambiguous long-range modern human dispersal detected by mtDNA and might have allowed the dispersal of several markers of modernity. A second one, within the last 20 ka signalled by L0d, may have been responsible for the spread of southern click-consonant languages to eastern Africa, contrary to the view that these eastern examples constitute relicts of an ancient, much wider distribution.

Future perspective and healthy lifestyle choices in adulthood.

Regardless of age, making healthy lifestyle choices is prudent. Despite that, individuals of all ages sometimes have difficulty choosing the healthy option. We argue that individuals' view of the future and position in the life span affects their current lifestyle choices. We capture the multidimensionality of future thinking by assessing 3 types of future perspective. Younger and older men and women (N = 127) reported global future time perspective, future health perspective, and perceived importance of future health-related events. They also rated their likelihood of making healthy lifestyle choices. As predicted, older participants indicated greater intention to make healthy choices in their current life than did younger participants. Compared to younger participants, older participants reported shorter global future time perspective and anticipated worse future health but perceived future health-related events as more important. Having a positive view of one's future health and seeing future health-related events as important were related to greater intention to make healthy lifestyle choices, but greater global future time perspective was not directly related to healthy choices. However, follow-up analyses suggested that greater global future time perspective indirectly affected healthy choices via a more positive view of future health. None of these relations were moderated by age. Individuals' perspective on the future is shown to be an important multidimensional construct affecting everyday healthy lifestyle choices for both younger and older adults. Implications for encouraging healthy choices across the adult life span are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Perspective View, Landsat Overlay, Salalah, Oman, Southern Arabian Peninsula

NASA Technical Reports Server (NTRS)

2000-01-01

This perspective view includes the city of Salalah, the second largest city in Oman. The city is located on the broad, generally bright coastal plain and includes areas of green irrigated crops. This view was generated from a Landsat image draped over a preliminary elevation model produced by the Shuttle Radar Topography Mission (SRTM). The edges of the dataset are to the upper right, left, and lower left. The Arabian Sea (lower right) is represented by the blue false-colored area. Vertical exaggeration of topography is 3X.

This scene illustrates how topography determines local climate and, in turn, where people live. The Arabian Peninsula is very arid. However, the steep escarpment of the Qara Mountains wrings moisture from the summer monsoons allowing for growth of natural vegetation (green along the mountain fronts and in the canyons), and soil development (dark brown areas), as well as cultural development of the coastal plain. The monsoons also provide moisture for Frankincense trees growing on the desert (north) side of the mountains. In ancient times, incense derived from the sap of the Frankincense tree was the basis for an extremely lucrative trade.

Landsat satellites have provided visible light and infrared images of the Earth continuously since 1972. SRTM topographic data match the 30-meter (99-foot)spatial resolution of most Landsat images and provide a valuable complement for studying the historic and growing Landsat data archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM project by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center,Sioux Falls, South Dakota.

Elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000.

Nutrition in Africa.

Village women have adopted techniques set down by UNICEF in achieving higher food production and, ultimately, self sufficiency. Women's cooperatives integrate kitchen gardening and irrigated agriculture in an effort to combat the complex nutritional problems in Africa. Projects also offered training in a variety of areas including management of plots, labor-saving technology--diesel-driven grinding mills, rice husking, machines, wells with hand pumps, motor pumps for irrigation, all geared towards women benefitting themselves by growing their own food and furthering their children's health and development. Projects such as the one in Senegal were undertaken in other regions of Africa, like the Sahel and the Wadis--low-lying areas. From these projects, aid agencies and governments have suggested a number of recommendations in seeking a solution to Africa's nutritional problems. 1st, a balance between production of cash crops and food for consumption is called for. 2nd, research is necessary to improve the quality of locally grown food as much as livestock. 3rd, governments should extend surface area cultivation, 4th, more research on the advantage of indigenous food plants, 5th, women should be in on all levels of decision making in food production, 6th, governments should increase women farmer's efficiency, and further women's access to land and credit and 7th, women should be provided with increased educational opportunities. Nutrition in developing countries cannot be viewed as an isolated phenomenon--solutions to nutritional development should include all aspects of the problem including health and nutrition education, growth monitoring, water supply, literacy, technological know-how, and agricultural and plant and soil conservation.

Despite the overwhelming evidence confirming the morbidity and mortality benefits of early initiation of highly active anti-retroviral therapy (HAART) in HIV-infected infants, some children are still disadvantaged from gaining access to care. The understanding of the maternal perspective on early infant HIV diagnosis and prompt initiation of HAART has not been adequately explored, especially in the rural communities of South Africa. This study explores the perspectives of mothers of HIV-exposed infants with regard to early infant diagnosis (EID) through a lens of social and structural barriers to accessing primary healthcare in OR Tambo district, Eastern Cape Province, South Africa. In this qualitative study, we conducted semi-structured interviews at two primary healthcare centres in the King Sabata Dalindyebo Municipality of the OR Tambo district, South Africa. Twenty-four purposive sample of mothers of HIV-exposed infants took part in the study. Interviews were tape-recorded, transcribed and field notes were obtained. The findings were triangulated with two focus group discussions in order to enrich and validate the qualitative data. Thematic content analysis was employed to analyse the data. The participants have fairly good knowledge of mother-to-child transmission of HIV and the risks during pregnancy, delivery and breastfeeding. The majority of participants were confident of the protection offered by anti-retroviral drugs provided during pregnancy, however, lack knowledge of optimal time for early infant diagnosis of HIV. Reasons for not accessing EID included fear of finding out that their child is HIV positive, feelings of guilt and/or shame and embarrassment with respect to raising an HIV infected infant. Personal experiences of HIV diagnosis and HAART were associated with participants' attitudes and beliefs toward care-seeking behaviours. Stigma resulting from their own disclosure to others reduced their likelihood of recommending EID to other members of

Drought vulnerability assessment of maize in Sub-Saharan Africa: Insights from physical and social perspectives

NASA Astrophysics Data System (ADS)

Kamali, Bahareh; Abbaspour, Karim C.; Wehrli, Bernhard; Yang, Hong

2018-03-01

Drought as a slow-onset phenomenon inflicts important losses to agriculture where the degree of vulnerability depends not only on physical variables such as precipitation and temperature, but also on societal preparedness. While the scopes of physical and social vulnerability are very different in nature, studies distinguishing these two aspects have been lacking. In this study we address the physical and social aspects of drought vulnerability of maize (CDVIphy and CDVIsoc) in Sub-Saharan Africa (SSA). To quantify vulnerability, we applied a probabilistic framework combining a Drought Exposure Index (DEI) with a physical or social Crop Failure Index, CFIphy or CFIsoc, respectively. DEI was derived from the exceedance probability of precipitation. Maize yields, simulated using the Environmental Policy Integrated Climate (EPIC) model, were used to build CFIphy, whereas the residual of simulated and FAO recorded yields were used to construct CFIsoc. The results showed that southern and partially central Africa are more vulnerable to physical drought as compared to other regions. Central and western Africa, however, are socially highly vulnerable. Comparison of CDVIphy and CDVIsoc revealed that societal factors cause more vulnerability than physical variables in almost all SSA countries except Nigeria and South Africa. We conclude that quantification of both drought vulnerabilities help a better characterization of droughts and identify regions where more investments in drought preparedness are required.

South Africa has the largest global HIV/AIDS epidemic, but barriers along the HIV care continuum prevent patients from initiating and adhering to antiretroviral therapy (ART). To qualitatively explore reasons for poor ART initiation and adherence rates from the unique perspective of community health workers (CHWs), we conducted focus groups during May–August 2014 with 21 CHWs in rural Msinga, KwaZulu-Natal. Interviews were audio-recorded, transcribed, and translated from Zulu into English. Hybrid deductive and inductive analytical methods were applied to identify emergent themes. Multiple psychosocial, socioeconomic, and socio-medical barriers acted at the level of the individual, social network, broader community, and healthcare environment to simultaneously hinder initiation of and adherence to ART. Key themes included insufficient patient education and social support, patient dissatisfaction with healthcare services, socioeconomic factors, and tension between ART and alternative medicine. Fear of lifelong therapy thwarted initiation whereas substance abuse principally impeded adherence. In conclusion, HIV/AIDS management requires patient counselling and support extending beyond initial diagnosis. Treating HIV/AIDS as a chronic rather than acute infectious disease is key to improving ART initiation and long-term adherence. Public health strategies include expanding CHWs' roles to strengthen healthcare services, provide longitudinal patient support, and foster collaboration with alternative medicine providers.

For successful communication, we need to understand the external world consistently with others. This task requires sufficiently similar cognitive schemas or psychological perspectives that act as filters to guide the selection, interpretation and storage of sensory information, perceptual objects and events. Here we show that when individuals adopt a similar psychological perspective during natural viewing, their brain activity becomes synchronized in specific brain regions. We measured brain activity with functional magnetic resonance imaging (fMRI) from 33 healthy participants who viewed a 10-min movie twice, assuming once a ‘social’ (detective) and once a ‘non-social’ (interior decorator) perspective to the movie events. Pearson's correlation coefficient was used to derive multisubject voxelwise similarity measures (inter-subject correlations; ISCs) of functional MRI data. We used k-nearest-neighbor and support vector machine classifiers as well as a Mantel test on the ISC matrices to reveal brain areas wherein ISC predicted the participants' current perspective. ISC was stronger in several brain regions—most robustly in the parahippocampal gyrus, posterior parietal cortex and lateral occipital cortex—when the participants viewed the movie with similar rather than different perspectives. Synchronization was not explained by differences in visual sampling of the movies, as estimated by eye gaze. We propose that synchronous brain activity across individuals adopting similar psychological perspectives could be an important neural mechanism supporting shared understanding of the environment.

To investigate the differences in acculturation experiences between parent and adolescent refugees from the Horn of Africa in Melbourne, Australia and to explore food beliefs and perceived health risks from an intergenerational perspective. Qualitative cross-sectional study involving a combination of semi-structured one-on-one interviews and focus group discussions. North-West suburbs of Melbourne, Australia. Eritrean, Ethiopian, Somali and Sudanese refugees. Using a purposeful sampling technique, twelve semi-structured face-to-face interviews (nine adults and three adolescents) and four in-depth focus groups (two with adolescents each containing six participants and two with adults one containing six participants and the other ten participants) were carried out. Thus overall data were obtained on fifteen adolescents and twenty-five parents. Qualitative analysis identified differences between parents and adolescents in relation to lifestyle, diet and physical activity. Views regarding health consequences of their changed diets also differed. Parental feeding practices encompassed a variety of methods and were enforced in an attempt by parents to control their children's dietary behaviours and prevent their drift away from traditional eating habits. These findings call for more research to contextualise dietary acculturation among refugee youth and the impact of migration on parenting styles and feeding practices in communities from the Horn of Africa. Preventive health programmes with Horn of Africa refugees need to acknowledge the effect of acculturation on diet and physical activity levels and a socio-cultural framework needs to be developed with respect to the importance and influence of the family environment.

AIDS in Africa.

Mokhobo, D

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.

Meteorological data fields 'in perspective'

Perspective display techniques can be applied to meteorological data sets to aid in their interpretation. Examples of a perspective display procedure applied to satellite and aircraft visible and infrared image pairs and to stereo cloud-top height analyses are presented. The procedure uses a sophisticated shading algorithm that produces perspective images with greatly improved comprehensibility when compared with the wire-frame perspective displays that have been used in the past. By changing the 'eye-point' and 'view-point' inputs to the program in a systematic way, movie loops that give the impression of flying over or through the data field have been made. This paper gives examples that show how several kinds of meteorological data fields are more effectively illustrated using the perspective technique.

Quality of life is an ill-defined term, as it means different things to different people. Quality of life has been well researched, especially with respect to people with cancer, but not necessarily from the perspective of the patient, and also, not in Third World, resource-poor countries. The objective of this study was to explore quality of life from the perspective of palliative care patients managed at a palliative care clinic serving a resource-poor community in Tshwane, South Africa. An exploratory, qualitative phenomenological study was conducted. The target population for this study was all patients managed at a palliative care clinic serving a resource-poor community in Tshwane. Self-report data were gathered by means of in-depth interviews. The data were analyzed using a template analysis style as well as content analysis using open coding. Data analysis was done concurrently with data gathering. Data saturation was reached after 10 interviews (n = 10). Three themes arose from the data: factors that had a positive influence on quality of life, factors that had a negative influence on quality of life, and experience of quality of life. Work played the most important role in quality of life whereas only one participant linked symptom control with quality of life. Experiencing symptoms, rejection, and stigmatization had a negative influence on quality of life. Friends and religion played a significant role and added to quality of life. Life was a daily struggle for survival. Poverty was so overwhelming that quality of life was primarily measured in terms of the ability to buy food and other basic commodities.

Snakebites in Africa and Europe: a military perspective and update for contemporary operations.

Snakebite envenoming is rare among military patients, with few cases reported in recent years. Increasingly, however, military operations are taking place in remote parts of Africa, which are inhabited by numerous species of venomous snake, and in Europe, where dangerous species exist but are less common. Bites from a venomous snake may prove fatal, and therefore military medics must be adequately prepared to manage them. This paper reviews the most medically significant species of venomous snake present in Africa and Europe, before suggesting an evidence-based approach to snakebite prevention and management, including possible changes to the UK's Clinical Guidelines for Operations. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Koosimile, Anthony T.; Suping, Shanah M.

2015-09-01

This paper takes the view that the emergence of some trends and practices in science education mirrors the influence of the process of globalisation in Anglophone Sub-Saharan Africa. Through a literature review, an attempt is made to link science education and globalisation by answering the question: 'What influence does globalisation have on science education in countries in Anglophone Sub-Saharan Africa?' The findings of the study show some significant convergence of what is valued in science education in Sub-Saharan Africa in areas such as pedagogy; English language as a medium of instruction; assessment of learning; mobility of students in the region; and in the frameworks for collaborative engagements among stakeholders in Sub-Saharan Africa. The paper concludes with a reflective end-piece calling for more case studies to help scrutinise further the influence of globalisation on science education in Sub-Saharan Africa.

Africa: rapid population increase retards development.

PubMed

1993-10-01

The Organization of African Unity (OAU), the African Development Bank (ADB) and the UN Economic Commission for Africa (ECA) have criticized African governments for not taking the problem of unchecked population growth seriously enough. "Until recently most African governments did not view rapid population growth as a matter for concern," said the OAU assistant secretary-general for political affairs, Machivenyika Mapuranga, at a seminar on 'population and development'. The OAU estimates that an annual average population increase of 3.1% far outstrips Africa's economic growth, which in 1992 was less than 1%. Mapuranga acknowledged that cutting the population increase is an uphill struggle, especially among rural communities. African agriculture is largely labor intensive, sustained by smallholders, which encourages farmers to have more children. Like other wage earners, African farmers look to support from their family when they grow old and, for that reason, the number of children also counts. But with agricultural production growing at an average annual rate of 2.5%, self-sufficiency in food remains an elusive goal. Cities in sub-Saharan Africa are growing much faster than the overall rate of population increase of 3.1% per year. Between 1980 and 1988 the region's urban population increased at the rate of 6.9% a year. Urban areas now account for nearly 30% of the sub-Saharan Africa population, currently put at 680 million. By 2025, approximately 700 million people are expected to live in urban areas. Despite migration to towns, the rural population is expected to rise more than 68%, reaching over 590 million. full text

2015-01-01

The establishment of minimal access surgery (MAS) in the last three decades brought new dimensions to surgical training. The sole role of traditional apprenticeship training model was challenged and adjunctive surgical simulation models were introduced. Knowledge of the trainees' educational needs is important in designing MAS training curriculum. To study the MAS educational needs of trainees from Africa, review MAS training models and offer recommendations for MAS training. Data was obtained from questionnaires filled by trainees from Africa who attended the monthly MAS training at the World Laparoscopy Hospital, India from October 2013 to May 2014 about their MAS educational needs. There were 38 trainees from different parts of Africa (Central, East, North, South and West Africa) with average age of 41.92 ± 8.67 years (minimum-28 years and maximum 63 years) and majority were males (92%). General surgeons constituted 57% while Gynaecologists were 41%. Only a quarter have MAS training integrated in their training curriculum. Box trainers, Animal models, live human surgeries and virtual reality simulation were the commonest models used in previous trainings and favoured in the educational needs for MAS training. Using cadaveric models and self sponsorship were deemphasised. Widespread application of MAS, globalisation and trainees educational needs call for establishing training programmes. Box trainers, animal models, live human surgeries and virtual reality simulators should be adopted and a synergy between Postgraduate surgical programmes, biomedical industry, universities and trainees will facilitate the setting of MAS skills laboratories and programmes.

Cape Town, South Africa, Anaglyph, Landsat Image over SRTM Elevation

NASA Technical Reports Server (NTRS)

2004-01-01

Cape Town and the Cape of Good Hope, South Africa, appear on the left (west) of this anaglyph view generated from a Landsat satellite image and elevation data from the Shuttle Radar Topography Mission (SRTM). The city center is located between Table Bay (upper left) and Table Mountain (just to the south), a 1,086-meter (3,563-foot) tall sandstone and granite natural landmark.

Cape Town enjoys a Mediterranean climate but must deal with the limited water supply characteristic of that climate. Until the 1890s the city relied upon streams and springs along the base of Table Mountain, then built a small reservoir atop Table Mountain to capture and store rainfall there (visible in this anaglyph when viewed at full resolution). Now the needs of a much larger population are met in part by much larger reservoirs such as seen well inland (upper right) at the Theewaterskloof Dam.

False Bay is the large bay to the southeast (lower right) of Cape Town, just around the Cape of Good Hope. It is one of the largest bays along the entire South African coast, but nearby Cape Town has its harbor at Table Bay. False Bay got its name because mariners approaching Cape Town from the east would see the prominent bay and falsely assume it to be the entrance to Cape Town harbor. Similarly, people often mistake the Cape of Good Hope as the southernmost point of Africa. But the southernmost point is actually Cape Agulhas, located just to the southeast (lower right) of this scene.

This anaglyph was created by draping a Landsat visible light image over an SRTM elevation model, and then generating two differing perspectives, one for each eye. When viewed through special glasses, the anaglyph is a vertically exaggerated view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter.

Coping Strategies in Late Adolescence: Relationships to Parental Attachment and Time Perspective.

Blomgren, Anna-Sara; Svahn, Kajsa; Åström, Elisabeth; Rönnlund, Michael

2016-01-01

The authors investigated adolescents' use of coping strategies in relation to attachment to parents and time perspective. Adolescents in Grade 3 upper secondary school (M age = 18.3 years, SD = 0.6 years; n = 160) completed the Inventory of Parent and Peer Attachment, the Zimbardo Time Perspective Inventory, and the Brief COPE. Correlational analyses showed that attachment to parents was associated with a more favorable view of the past (higher past positive and lower past negative), a less fatalistic view of the present, and a more favorable view of the future (higher future positive and lower future negative). Parental attachment accounted for significant variance in composite coping scores (adaptive and maladaptive) when entered before, but not after, time perspective subscales in hierarchical regression analyses. However, time perspective (mainly present hedonistic and positive or negative future) predicted adaptive or maladaptive coping over and beyond attachment. The results are consistent with the hypothesis that most of the relationship between adolescents' attachment to parents and coping is mediated by individual differences in time perspective. By contrast, factors other than attachment to parents (e.g., temperament) must be considered to fully account for the relationship between time perspective and coping.

Collaboration involves direct and open communication and respect for different perspectives. In particular, religious literature has many references to collaboration. This study is a report of knowledge synthesis based on qualitative systematic review by content analysis. The study surveys the concept of collaboration from the Islamic point of view and intends to answer the question, 'Does the Quran deal with the use of collaboration in human activities?' This study was conducted using electronic documents from websites related to Islamic and Quran sciences, such as Howzah.net, Nashriat.ir, Tebyan.net and Google Scholar from 1950 until 2013 by focusing on the keywords, collaboration and Islam, and then retrieving the Islamic document (Quran and Hadith). The language in which the search was conducted was English and Persian. Nearly, 28 articles and 72 books related to this topic were found and after applying the search criteria, only 13% of the references were found to be applicable. In the Quran, collaboration is equivalent to Taavon, and Muslims are requested to collaborate in their affairs and never collaborate with each other for illegal affairs. Islam asserts that everyone requires social relationship in their life. God has enacted mutual rights for people and meeting these requirements is only possible through collaboration and respecting mutual rights.

Gaze and viewing angle influence visual stabilization of upright posture

PubMed Central

Ustinova, KI; Perkins, J

2011-01-01

Focusing gaze on a target helps stabilize upright posture. We investigated how this visual stabilization can be affected by observing a target presented under different gaze and viewing angles. In a series of 10-second trials, participants (N = 20, 29.3 ± 9 years of age) stood on a force plate and fixed their gaze on a figure presented on a screen at a distance of 1 m. The figure changed position (gaze angle: eye level (0°), 25° up or down), vertical body orientation (viewing angle: at eye level but rotated 25° as if leaning toward or away from the participant), or both (gaze and viewing angle: 25° up or down with the rotation equivalent of a natural visual perspective). Amplitude of participants’ sagittal displacement, surface area, and angular position of the center of gravity (COG) were compared. Results showed decreased COG velocity and amplitude for up and down gaze angles. Changes in viewing angles resulted in altered body alignment and increased amplitude of COG displacement. No significant changes in postural stability were observed when both gaze and viewing angles were altered. Results suggest that both the gaze angle and viewing perspective may be essential variables of the visuomotor system modulating postural responses. PMID:22398978

Comparing artistic and geometrical perspective depictions of space in the visual field

Which is the most accurate way to depict space in our visual field? Linear perspective, a form of geometrical perspective, has traditionally been regarded as the correct method of depicting visual space. But artists have often found it is limited in the angle of view it can depict; wide-angle scenes require uncomfortably close picture viewing distances or impractical degrees of enlargement to be seen properly. Other forms of geometrical perspective, such as fisheye projections, can represent wider views but typically produce pictures in which objects appear distorted. In this study we created an artistic rendering of a hemispherical visual space that encompassed the full visual field. We compared it to a number of geometrical perspective projections of the same space by asking participants to rate which best matched their visual experience. We found the artistic rendering performed significantly better than the geometrically generated projections. PMID:26034563

In this paper, the authors present contrasting perspectives on the legacy of this key paper. First, from the perspective of classical person-centered therapy, Freire describes the context for this key paper within the wider frame of Rogers' body of work and emphasizes its continuing importance and relevance. Second, Elliott offers a personal history from the point of view of a psychotherapy researcher and process-experiential therapist. These two perspectives represent two major and distinct views of Rogers' legacy from within his direct intellectual and therapeutic descendents.

The United Nations Education Science Culture and Communication Organization (UNESCO) has recently launched a new Earth Science Education Initiative in Africa. The overall intention of this Initiative is to support the development of the next generation of earth scientists in Africa who are equipped with the necessary tools, networks and perspectives to apply sound science to solving and benefiting from the challenges and opportunities of sustainable development. The opportunities in the earth sciences are great, starting with traditional mineral extraction and extending into environmental management such as climate change adaptation, prevention of natural hazards, and ensuring access to drinking water. The Earth Science Education Initiative has received strong support from many different types of partners. Potential partners have indicated an interest to participate as organizational partners, content providers, relevant academic institutes, and funders. Organizational partners now include the Geological Society of Africa (GSAf), International Center for Training and Exchanges in the Geosciences (CIFEG), Association of African Women Geoscientists (AAWG), International Year of Planet Earth (IYPE), and International Union of Geological Sciences (IUGS). The activities and focus of the Initiative within the overall intention is being developed in a participatory manner through a series of five regional workshops in Africa. The objective of these workshops is to assess regional capacities and needs in earth science education, research and industry underlining existing centers of excellence through conversation with relevant regional and international experts and plotting the way ahead for earth science education. This talk will provide an update on the outcomes of the first three workshops which have taken place in Luanda, Angola; Assiut, Egypt; and Cape Town; South Africa.

Accuracy of gestational age estimation from last menstrual period among women seeking abortion in South Africa, with a view to task sharing: a mixed methods study.

The requirement for ultrasound to establish gestational age among women seeking abortion can be a barrier to access. Last menstrual period dating without clinical examination should be a reasonable alternative among selected women, and if reliable, can be task-shared with non-clinicians. This study determines the accuracy of gestational age estimation using last menstrual period (LMP) assessed by community health care workers (CHWs), and explores providers' and CHWs' perspectives on task sharing this activity. The study purpose is to expand access to early medical abortion services. We conducted a multi-center cross-sectional study at four urban non-governmental reproductive health clinics in South Africa. CHWs interviewed women seeking abortion, recorded their LMP and gestational age from a pregnancy wheel if within 63 days. Thereafter, providers performed a standard examination including ultrasound to determine gestational age. Lastly, investigators calculated gestational age for all LMP dates recorded by CHWs. We compared mean gestational age from LMP dates to mean gestational age by ultrasound using t-tests and calculated proportions for those incorrectly assessed as eligible for medical abortion from LMP. In addition, in-depth interviews were conducted with six providers and seven CHWs. Mean gestational age was 5 days (by pregnancy wheel) and 9 days (by LMP calculation) less than ultrasound gestational age. Twelve percent of women were eligible for medical abortion by LMP calculation but ineligible by ultrasound. Uncertainty of LMP date was associated with incorrect assessment of gestational age eligibility for medical abortion (p = 0.015). For women certain their LMP date was within 56 days, 3% had ultrasound gestational ages >70 days. In general, providers and CHWs were in favour of task sharing screening and referral for abortion, but were doubtful that women reported accurate LMP dates. Different perspectives emerged on how to implement task sharing

Out of Africa: the importance of rivers as human migration corridors

NASA Astrophysics Data System (ADS)

Ramirez, J. A.; Coulthard, T. J.; Rogerson, M.; Barton, N.; Bruecher, T.

2013-12-01

The route and timing of Homo sapiens exiting Africa remains uncertain. Corridors leading out of Africa through the Sahara, the Nile Valley, and the Red Sea coast have been proposed as migration routes for anatomically modern humans 80,000-130,000 years ago. During this time climate conditions in the Sahara were wetter than present day, and monsoon rainfall fed rivers that flowed across the desert landscape. The location and timing of these rivers may have supported human migration northward from central Africa to the Mediterranean coast, and onwards to Europe or Asia. Here, we use palaeoclimate rainfall and a hydrological model to spatially simulate and quantitatively test the existence of three major rivers crossing the Sahara from south to north during the time of human migration. We provide evidence that, given realistic underlying climatology, the well-known Sahabi and Kufrah rivers very likely flowed across modern day Libya and reached the coast. More unexpectedly an additional river crossed the core of the Sahara through Algeria (Irharhar river) and flowed into the Chotts basin. The Irharhar river is unique, because it links locations in central Africa experiencing monsoon climates with temperate coastal Mediterranean environments where food and resources were likely abundant. From an ecological perspective, this little-known corridor may prove to be the most parsimonious migration route. Support for the Irharar as a viable migration corridor is provided by its geographic proximity to middle Stone Age archaeological artefacts found in North Africa. Our new, highly novel approach provides the first quantitative analysis of the likelihood that rivers occurred during the critical period of human migration out of Africa. Simulated probability of surface water in North Africa during the last interglacial and the location of tools and ornaments from the Middle Stone Age.

Inferring Perspective Versus Getting Perspective: Underestimating the Value of Being in Another Person's Shoes.

PubMed

Zhou, Haotian; Majka, Elizabeth A; Epley, Nicholas

2017-04-01

People use at least two strategies to solve the challenge of understanding another person's mind: inferring that person's perspective by reading his or her behavior (theorization) and getting that person's perspective by experiencing his or her situation (simulation). The five experiments reported here demonstrate a strong tendency for people to underestimate the value of simulation. Predictors estimated a stranger's emotional reactions toward 50 pictures. They could either infer the stranger's perspective by reading his or her facial expressions or simulate the stranger's perspective by watching the pictures he or she viewed. Predictors were substantially more accurate when they got perspective through simulation, but overestimated the accuracy they had achieved by inferring perspective. Predictors' miscalibrated confidence stemmed from overestimating the information revealed through facial expressions and underestimating the similarity in people's reactions to a given situation. People seem to underappreciate a useful strategy for understanding the minds of others, even after they gain firsthand experience with both strategies.

The Earliest Colubroid-Dominated Snake Fauna from Africa: Perspectives from the Late Oligocene Nsungwe Formation of Southwestern Tanzania

PubMed Central

McCartney, Jacob A.; Stevens, Nancy J.; O’Connor, Patrick M.

2014-01-01

The extant snake fauna has its roots in faunal upheaval occurring across the Paleogene - Neogene transition. On northern continents, this turnover is well established by the late early Miocene. However, this transition is poorly documented on southern landmasses, particularly on continental Africa, where no late Paleogene terrestrial snake assemblages are documented south of the equator. Here we describe a newly discovered snake fauna from the Late Oligocene Nsungwe Formation in the Rukwa Rift Basin of Tanzania. The fauna is small but diverse with eight identifiable morphotypes, comprised of three booids and five colubroids. This fauna includes Rukwanyoka holmani gen. et sp. nov., the oldest boid known from mainland Africa. It also provides the oldest fossil evidence for the African colubroid clade Elapidae. Colubroids dominate the fauna, comprising more than 75% of the recovered material. This is likely tied to local aridification and/or seasonality and mirrors the pattern of overturn in later snake faunas inhabiting the emerging grassland environments of Europe and North America. The early emergence of colubroid dominance in the Rukwa Rift Basin relative to northern continents suggests that the pattern of overturn that resulted in extant faunas happened in a more complex fashion on continental Africa than was previously realized, with African colubroids becoming at least locally important in the late Paleogene, either ahead of or as a consequence of the invasion of colubrids. The early occurrence of elapid snakes in the latest Oligocene of Africa suggests the clade rapidly spread from Asia to Africa, or arose in Africa, before invading Europe. PMID:24646522

Introduction. Shrines, substances and medicine in sub-Saharan Africa: archaeological, anthropological, and historical perspectives

Whereas shrines in Africa, and to a lesser extent their links with medicine and healing, have been extensively studied by historians and anthropologists, they have been largely neglected by archaeologists.

Difficulties certainly exist in defining medicine shrines, substances and practices archaeologically, yet research can take various forms – scapegoats and figural representations of disease; divination and diagnosis; trade and spread of medicinal substances, shrines, and amulets; syncretism of different traditions and materiality; the material culture associated with healing and medicinal substance; depictions in rock art; genetic research. A move beyond palaeopathology is required to begin to understand the archaeology of medicine shrines, substances, practices and healing in sub-Saharan Africa. PMID:21810034

"It's for a good cause, isn't it?" - Exploring views of South African TB research participants on sample storage and re-use

Background The banking of biological samples raises a number of ethical issues in relation to the storage, export and re-use of samples. Whilst there is a growing body of literature exploring participant perspectives in North America and Europe, hardly any studies have been reported in Africa. This is problematic in particular in light of the growing amount of research taking place in Africa, and with the rise of biobanking practices also on the African continent. In order to investigate the perspectives of African research participants, we conducted a study with research participants in a TB study in the Western Cape, South Africa. Methods Semi-structured interviews were conducted using an interview guide which drew on the most prominent themes expressed in current literature on sample storage, re-use and exportation. Interviews were conducted in Afrikaans and subsequently translated into English by the same interviewer. Interviews were transcribed verbatim and analysed qualitatively. Results The results of our study indicate that the majority of participants were supportive of giving one-time consent to the storage and re-use of their samples. The concept of research being for a “good cause” was a central prerequisite. Additionally, a significant minority requested that they be re-contacted if a future use was not stipulated on the original consent. There was also considerable variation in how participants understood the concept of a ‘good cause’, with participants describing three distinct categories of research, of which two were generally thought to constitute ‘good cause’ research. Research that was for-profit was considered to fall outside the spectrum of ‘good cause’ research. Participants displayed confidence in the abilities of the researchers to make future decisions regarding sample use, but seemed unaware of the role of ethics committees in either this process or more generally. Conclusions Participants expressed a wide and complex

Children with hearing loss who happen to reside in Africa deserve the chance to develop according to their potential as much as their peers living in more affluent regions. This leaves a moral obligation to pursue ways of initiating, developing,and growing early hearing detection and intervention services in Africa. For these reasons, the first EHDI Africa international conference was held in Johannesburg, South Africa, in 2007 (13-14 August). The theme was 'Building bridges in Africa: Early childhood development for children with hearing loss'. This special issue contains several reports from the EHDI Africa conference.

An intra-cultural investigation of susceptibility to 'perspective' and 'non-perspective' spatial illusions.

Conventional Müller-Lyer and modified Müller-Lyer (without 'perspective' cues) illusions were presented to two samples of children aged between eight and 19, matched in education, but living in 'carpentered' and 'uncarpentered' environments in Zambia. Traditional differences in susceptibility have been obtained with both the variations of the Müller-Lyer illusion. In view of the lack of perspective cues in one of these, it is concluded that the perspective theory as presented within the 'carpentered world hypothesis' is inadequate. Since these differences are intra-cultural, they also do not support the hypothesis which suggests that cross-cultural variations in illusion susceptibility are due to genetic factors--such as macular (or retinal) pigmentation.

Individualism and the field viewpoint: cultural influences on memory perspective.

Two perspectives from which memories can be retrieved have been distinguished: field resembles the view from the first-person vantage point of original experience, whereas observer resembles the view from the third-person vantage point of a spectator. There is evidence that the incidences of the two types of perspective differ between at least two different cultural groups. It is hypothesised here that this is a special case of a more general relation between memory perspective and cultural individualism, such that field and observer perspectives are more prevalent among people from, respectively, relatively individualist and relatively collectivist societies. Memory perspectives adopted by participants from a range of different countries were recorded, and were found to vary in the predicted manner. Regression analysis showed that the potential effects of three other cultural variables - uncertainty avoidance, masculinity and, to a lesser extent, power distance - were eclipsed by the influence of individualism, and the implications are discussed.
