A professional development programme for teachers of the deaf in South Africa

OpenAIRE

2012-01-01

D.Ed. Education for the Deaf in South Africa appears to be insufficiently researched, contributing to a less than ideal educational situation. Teachers are not trained to address the special needs of Deaf learners, there is limited cohesive instructional theory and the educational policy focussing on the needs of Deaf learners is limited in both range and depth. Due to the ineffectiveness of Deaf education in South Africa, the majority of Deaf school leavers leave school linguistically imp...

AN OUTLINE OF THE EUROPE – SOUTH AFRICA RELATIONS DURING AND POST THE APARTHEID ERA

Directory of Open Access Journals (Sweden)

Konstantinos Margaritis

2012-12-01

Full Text Available South Africa was always a main interest region for European countries. The United Kingdom, the Netherlands, France and many others at lesser extent, tried to establish control over thecountry due to its special geographical position. On the other hand, since 1948, South Africa had been characterized by a tremendous regime, the so-called apartheid. The idea of this paper is to clarify the position of certain European countries towards South Africa during this severe period for the latest and to outline the major development agreements between the EC/EU and South Africa after the fall of apartheid, since South Africa is an important trade partner for the Union.

Interim report on the special research project 'exposure to environmental radiation due to nuclear facilities'

International Nuclear Information System (INIS)

1981-03-01

This special research project was started in 1978 as five-year plan. The purposes are to clarify the aspect of radiation exposure in human bodies due to the radioactive substances brought into the environment regarding the utilization of atomic energy, its mechanism and various factors affecting it, and to contribute to the evaluation of exposure dose, the reduction of radiation exposure, the conditions of locating nuclear facilities and the improvement of the method of disposing radioactive wastes. In addition to the fields treated in the previous special research project, the experimental research concerning the metabolism of environmental radioactive nuclides in bodies, namely the problem of the peculiarity of radioactive nuclide kinetics in infants and fetuses different from adults and the possibility of causing the changes in the intake and metabolism of nuclides in foods by the difference in their states of existence, was newly included. Also the research concerning the method of evaluating the absorbed dose in human organs at the time of irradiation outside and inside bodies in a new subject. Accordingly, this special research project is composed of (1) the research concerning the radionuclide kinetics in the environment, (2) the research concerning the radionuclide kinetics in bodies, (3) the research concerning the measurement and evaluation of dose absorbed in internal organs due to environmental radiation, and (4) the research concerning the monitoring of low level environmental radiation. The results obtained so far are reported. (Kako, I.)

Food inflation in South Africa: some implications for economic policy.

Science.gov (United States)

Rangasamy, Logan

2011-01-01

This paper analyses the trends in food price movements in South Africa between 1980 and 2008. There are three main results emanating from the analysis in this paper. Firstly, food price movements have played a large role in generating inflationary episodes in South Africa. Secondly, while external influences do matter, South African food price movements are mainly due to domestic influences. This implies that national policy has an important role to play in taming domestic food price inflation. Thirdly, given the strong second round impacts, food price movements warrant special attention in monetary policymaking. Core measures of inflation that exclude food price movements may not accurately reflect the underlying inflationary pressures in the economy and could compromise the attainment of the goal of price stability.

Tuberculosis due to Mycobacterium bovis in humans in the south-west region of Ireland: is there a relationship with infection prevalence in cattle?

LENUS (Irish Health Repository)

Cotter, T P

2012-02-03

OBJECTIVE: To compare the incidence of tuberculosis due to Mycobacterium bovis in humans to the prevalence of M. bovis infection in cattle in south-west Ireland and discuss possible links between them. SETTING: In the south-west region of Ireland, a mixed urban and rural community (pop. 536,000), there is a residuum of human tuberculosis caused by M. bovis. METHODS: A retrospective analysis of the incidence of culture-positive M. bovis disease in humans in south-west Ireland from 1983 to 1994 and of the results of tuberculin testing in cattle from 1978 to 1994 for the same region. RESULTS: One to five cases of human tuberculosis due to M. bovis were recorded per year while the overall prevalence of bovine infection fell gradually during the period of study from 467 tuberculin-positive animals per 100,000 cattle tested in 1983 to 158 per 100,000 in 1994. CONCLUSION: The low incidence plateau of human tuberculosis due to M. bovis together with the decline in prevalence of animal infection in the overall period studied suggest a cut-off in the animal to human chain of infection at two points; the animal source and the ingestion of (now pasteurized) milk. This would suggest that disease in humans is now due to reactivation of previous foci of infection which were acquired when milk pasteurization was not compulsory. Based on this, we would anticipate a further reduction and possible elimination of human tuberculosis due to M. bovis in this region in the next 10-15 years.

South African, Rural ICT Implementation: a critical retrospective application of Latour's due process model

Directory of Open Access Journals (Sweden)

Jo Rhodes

2004-05-01

Full Text Available The potential developmental role of ICTs can pressurise governments to engage in ‘catch up’ and ‘leapfrog’. Consequently, analysis of the accompanying socio-political dimensions and risks can be, disastrously, neglected. This paper examines a specific technology implementation – a South African government sponsored telecentre using Latour’s Due Process model, an analytical tool grounded in Actor-Network Theory, where technology implementation is viewed as a symmetrical treatment of technology and society within a single collective. It is used here, retrospectively, to make sense of why the telecentre both failed to institutionalise within a successful actor-network, and, contributed to the destabilization and partial destruction of a successfully established women’s development organisation.

GASNet-EX Performance Improvements Due to Specialization for the Cray Aries Network

Energy Technology Data Exchange (ETDEWEB)

Hargrove, Paul H.; Bonachea, Dan

2018-03-27

This document is a deliverable for milestone STPM17-6 of the Exascale Computing Project, delivered by WBS 2.3.1.14. It reports on the improvements in performance observed on Cray XC-series systems due to enhancements made to the GASNet-EX software. These enhancements, known as “specializations”, primarily consist of replacing network-independent implementations of several recently added features with implementations tailored to the Cray Aries network. Performance gains from specialization include (1) Negotiated-Payload Active Messages improve bandwidth of a ping-pong test by up to 14%, (2) Immediate Operations reduce running time of a synthetic benchmark by up to 93%, (3) non-bulk RMA Put bandwidth is increased by up to 32%, (4) Remote Atomic performance is 70% faster than the reference on a point-to-point test and allows a hot-spot test to scale robustly, and (5) non-contiguous RMA interfaces see up to 8.6x speedups for an intra-node benchmark and 26% for inter-node. These improvements are available in the GASNet-EX 2018.3.0 release.

This report describes the collaboration between the South Texas Specialized Crimes and Narcotics Task Force (STSCNTF) and Sandia National Laboratories (SNL) in a field test that provided prototype hand-held trace detection technology for use in counter-drug operations. The National Institute of Justice (NIJ)/National Law Enforcement and Corrections Technology Center (NLECTC)/Border Research and Technology Center (BRTC) was contacted by STSCNTF for assistance in obtaining cutting-edge technology. The BRTC created a pilot project for Sandia National Laboratories (SNL) and the STSCNTF for the use of SNL’s Hound, a hand-held sample collection and preconcentration system that, when combined with a commercial chemical detector, can be used for the trace detection of illicit drugs and explosives. The STSCNTF operates in an area of high narcotics trafficking where methods of concealment make the detection of narcotics challenging. Sandia National Laboratories’ (SNL) Contraband Detection Department personnel provided the Hound system hardware and operational training. The Hound system combines the GE VaporTracer2, a hand-held commercial chemical detector, with an SNL-developed sample collection and preconcentration system. The South Texas Task force reported a variety of successes, including identification of a major shipment of methamphetamines, the discovery of hidden compartments in vehicles that contained illegal drugs and currency used in drug deals, and the identification of a suspect in a nightclub shooting. The main advantage of the hand-held trace detection unit is its ability to quickly identify the type of chemical (drugs or explosives) without a long lag time for laboratory analysis, which is the most common analysis method for current law enforcement procedures.

Occupational asthma due to manual metal-arc welding of special stainless steels.

Hannu, T; Piipari, R; Kasurinen, H; Keskinen, H; Tuppurainen, M; Tuomi, T

2005-10-01

Occupational asthma (OA) can be induced by fumes of manual metal-arc welding on stainless steel. In recent years, the use of special stainless steels (SSS) with high chromium content has increased. This study presents two cases of OA caused by manual metal-arc welding on SSS. In both cases, the diagnosis of OA was based on respiratory symptoms, occupational exposure and positive findings in the specific challenge tests. In the first case, a 46-yr-old welder had experienced severe dyspnoea while welding SSS (SMO steel), but not in other situations. Challenge tests with both mild steel and stainless steel using a common electrode were negative. Welding SSS with a special electrode caused a delayed 37% drop in forced expiratory volume in one second (FEV1). In the second case, a 34-yr-old male had started to experience dyspnoea during the past few years, while welding especially SSS (Duplex steel). The workplace peak expiratory flow monitoring was suggestive of OA. Challenge tests with both mild steel and stainless steel using a common electrode did not cause bronchial obstruction. Welding SSS with a special electrode caused a delayed 31% drop in FEV1. In conclusion, exposure to manual metal-arc welding fumes of special stainless steel should be considered as a new cause of occupational asthma.

Gastroenterology training in private hospitals: India vs South Africa

Mulder, Chris Jacob Johan; Puri, Amarender Singh; Reddy, Duvvur Nageshwar

2010-01-01

In South Africa, nurses and doctors are emigrating in significant numbers. Job satisfaction, safety and ensuring career progression are important in retaining doctors to make a career in Republic of South Africa (RSA). Due to budgetary constraints many hospitals have not been upgraded. Coming home after overseas training seems difficult. In RSA it takes a minimum of 13 years for a young specialist to become registered and 15 years for subspecialists. Career progression, creating more specialist trainees in public and private hospitals and shortening the period of professional training are potential solutions to the problem. India, which has a population of more than 1 billion people, is struggling with similar problems. For the past 10-15 years, private hospitals have assisted in manpower development for medical specialist and subspecialist careers. Currently their private sector trains 60% of their recognised (sub)specialities fellows. A national task force for specialist training in RSA should be instituted. It should discuss, based on the current status and projected specialist and subspecialist personnel requirements, the future structure and logistics of training needs. This is required in all subspecialities including gastroenterology, as has been done in India. It is hoped that as a consequence well-trained doctors, similar to those in India, might move to provincial hospitals in rural areas, upgrading the medical services and keeping medical power in South Africa. South Africa should become a model for Sub-Saharan Africa, as India already is for South-East Asia. PMID:20180232

Over two-thirds of the world's cancer deaths occur in economically developing countries; however, the societal costs of cancer have rarely been assessed in these settings. Our aim was to estimate the value of productivity lost in 2012 due to cancer-related premature mortality in the major developing economies of Brazil, the Russian Federation, India, China and South Africa (BRICS). We applied an incidence-based method using the human capital approach. We used annual adult cancer deaths from GLOBOCAN2012 to estimate the years of productive life lost between cancer death and pensionable age in each country, valued using national and international data for wages, and workforce statistics. Sensitivity analyses examined various methodological assumptions. The total cost of lost productivity due to premature cancer mortality in the BRICS countries in 2012 was $46·3 billion, representing 0·33% of their combined gross domestic product. The largest total productivity loss was in China ($28 billion), while South Africa had the highest cost per cancer death ($101,000). Total productivity losses were greatest for lung cancer in Brazil, the Russian Federation and South Africa; liver cancer in China; and lip and oral cavity cancers in India. Locally-tailored strategies are required to reduce the economic burden of cancer in developing economies. Focussing on tobacco control, vaccination programs and cancer screening, combined with access to adequate treatment, could yield significant gains for both public health and economic performance of the BRICS countries.

Search for GLAST gamma ray burst triggers due to particle precipitation in the South Atlantic Anomaly

International Nuclear Information System (INIS)

Augusto, C. R. A.; Navia, C. E.; Tsui, K. H.

2008-01-01

When GLAST is in the South Atlantic Anomaly (SAA), the rate of charged particles is too high to be efficiently filtered out. Moreover the high rate can cause saturation effects in the readout electronics and the sensors must be turned off. The SAA area relative to the total area of GLAST's orbit is approximately 12.5% and GLAST spends 18% of the time in it. In spite of these cares, we show in this work that, due to drift processes, particle precipitation can still trigger GLAST when it is close to the SAA region. Here, we report two GLAST gamma ray burst monitor (GBM) triggers, trigger 239895229 and trigger 239913100, on August, 08, 2008 whose characteristics are similar to the ones observed in the Swift-BAT noise triggers (due to particle precipitation in the SAA region). Both GLAST triggers happened during a plentiful particle precipitation in the SAA region, observed by Tupi telescopes at the ground with their trigger coordinates close to the field of view of the telescopes. Details of these results are reported.

'Development' is to improve the quality of people's lives by creating an environment for them to engage in a wide range of activities, to be healthy and well nourished, to be knowledgeable and to be able to participate in the community life. The Human Development Index (HDI) is a multi-dimensional index of development as it is the combination of three development indices- health index, education index and income index. This article attempts to compare the HDI and its components between various South East Asian countries. Secondary data is used. India's position on the HDI scale is equivalent to the South East Asian average and rank 134 out of more than 190 countries. In South East Asia, India stood fifth in HDI, behind Sri Lanka, Thailand, Maldives and Indonesia. Country has launched several schemes and programs to improve the health indicators, to provide elementary education to every child and to alleviate poverty. India's HDI value has improved with time but still country has a long way to go in achieving an acceptable HDI. Need is to strengthen the existing schemes and programs.

South Asian aerosols in perspective: Preface to the special issue

2016-01-01

The south Asian region is one the world's most populous and fast-developing regions. The more than 1.7 billion population (˜24% of the world population) with highly diverse living habits, fast growing industrial and transport sectors, large and increasing demand for power, diverse fuel use for domestic and industrial purposes, and equally diverse geographical features make this region a large cauldron of emissions and atmospheric processes. It is being increasingly recognized to be among the global hotspots of aerosols and anthropogenic trace gases. The complex geography of this region adds considerable amount of natural aerosols (sea spray, windblown desert dust, pollen, etc) into the atmosphere, which mix with the man-made ones, making the aerosol environment one of the most complex in the world. The large spatial diversity of the sources coupled with the varying atmospheric dynamics, driven by the contrasting monsoons and the topography, make South Asia's aerosol and pollution very difficult to characterize, to model and to plan effective mitigation measures, despite the fairly good knowledge on their implications to radiative and climate forcing, health effects and environmental degradation. In the recent years, there have been several reports on the impact of aerosols (more importantly black carbon - BC) on the regional and global climate system including Asian monsoon, with the caveats of long-term impacts on the livelihoods of tens of millions of people in this region; though specifics of these are not yet unequivocally established. While tropospheric perturbations would produce strong regional signatures, their global impacts still remain marginally above the uncertainty levels (IPCC, 2013). There have been several recent investigations showing that deposition of aerosol black carbon (BC) on snow can reduce the snow albedo, leading to enhanced absorption of solar radiation and hence faster melting rates of glaciers. Though several investigators have

Manufacturing of Nano gold cosmetics was done at PT. Gizi Indonesia. Clinical trials to cosmetics data supported that cosmetics are able to treat skin health which has been reported partially. For special cases, the recovery process of facial skin damage should also receive attention including cases of facial skin damage caused by chemicals such as phenol, HCl, aqua regia or other harsh chemicals. The problem determined whether the Nano gold is able to recover skin damage due to the harsh chemicals. This clinical trial data on the forms of early skin damage caused by phenol was delivered in the forms of facial photos patients. The recovery progress of facial skin condition was obtained every week for two months. The data included the forms of widespread wounds during the recovery process.

1981-01-01

The current position of practical preclinical and clinical training in dento-maxillo-facial radiography for dental students and oral hygiene students in South Africa is reviewed. Special attention is given to factors in methodology which have an influence on radiation protection. Results indicate that there is a fairly high degree of standardization in dento-maxillo-facial radiography instruction in South Africa. The preference for the lead-lined or shielded open-ended cones is in keeping with the tenets of radiation protection. The use of pointed cones for intraoral radiography is not a good choice, as this causes scatter radiation. The wide use of the Rinn XCP(R) filmholding device in South African dental schools for the parallelling technique lessens the chance of cone cutting, and hence reduces the likelihood of needing to reexpose the patient due to that technical error. Additionally, the parallelling technique allows a more accurate assessment of alveolar bone loss from periodontal disease, and allows a better judgement of the relationship between the roots of maxillary teeth and the floor of the maxillary sinus, than does the bisecting angle technique. During the past decade, fiarly consistent parameters have been developed in dento-maxillo-facial radiography concerning preclinical and clinical training of dental and oral hygiene students [af

Esterhuizen, Tonya; Gathiram, Prem

2009-01-01

ABSTRACT Background Family physicians are trained to treat a wide range of diseases, treatment being centred on the patient, family and community irrespective of age, gender, or ethnic or racial background. To deal with inequalities in health care, the South African government introduced the concept of a district health system in 1997. It was only in August 2007, however, that family medicine was legislated as a speciality. This study was undertaken prior to the enactment of this legislation. Method A descriptive quantitative study using a self-administered questionnaire was undertaken. A convenience sampling technique was used (N = 60) to assess the reactions of medical practitioners towards the impending legislation. Results Overall, 60% of the sample was in favour of the legislation. There were no significant differences between those working in the private and public sectors or between generalists and specialists. With regard to those not in favour of the legislation compared to those in favour of the legislation, a significantly increased number answered the following statements in the affirmative: (i) ‘I already carry out the functions of a family physician’ (p = 0.001), (ii) ‘They [specialist family physicians] will not be as qualified as specialists in other categories’ (p = 0.005), (iii) ‘It will have a negative impact on general practice’ (p competitiveness’ (p = 0.021), (v) ‘It will not have any effect on patient care’ (p = 0.010) and (vi) ‘There is no need for such a speciality’ (p = 0.001). Conclusion We concluded that the majority were in favour of the legislation being implemented.

Analysis and evaluation of WRF microphysical schemes for deep moist convection over south-eastern South America (SESA) using microwave satellite observations and radiative transfer simulations

Science.gov (United States)

Sol Galligani, Victoria; Wang, Die; Alvarez Imaz, Milagros; Salio, Paola; Prigent, Catherine

2017-10-01

In the present study, three meteorological events of extreme deep moist convection, characteristic of south-eastern South America, are considered to conduct a systematic evaluation of the microphysical parameterizations available in the Weather Research and Forecasting (WRF) model by undertaking a direct comparison between satellite-based simulated and observed microwave radiances. A research radiative transfer model, the Atmospheric Radiative Transfer Simulator (ARTS), is coupled with the WRF model under three different microphysical parameterizations (WSM6, WDM6 and Thompson schemes). Microwave radiometry has shown a promising ability in the characterization of frozen hydrometeors. At high microwave frequencies, however, frozen hydrometeors significantly scatter radiation, and the relationship between radiation and hydrometeor populations becomes very complex. The main difficulty in microwave remote sensing of frozen hydrometeor characterization is correctly characterizing this scattering signal due to the complex and variable nature of the size, composition and shape of frozen hydrometeors. The present study further aims at improving the understanding of frozen hydrometeor optical properties characteristic of deep moist convection events in south-eastern South America. In the present study, bulk optical properties are computed by integrating the single-scattering properties of the Liu(2008) discrete dipole approximation (DDA) single-scattering database across the particle size distributions parameterized by the different WRF schemes in a consistent manner, introducing the equal mass approach. The equal mass approach consists of describing the optical properties of the WRF snow and graupel hydrometeors with the optical properties of habits in the DDA database whose dimensions might be different (Dmax') but whose mass is conserved. The performance of the radiative transfer simulations is evaluated by comparing the simulations with the available coincident

Learners with disabilities lag far behind their peers without disabilities in achievement, graduation rates, post-school education and employment outcomes [4]. Against the current state of education affairs in South Africa, where curriculum models for learners with special educational needs (LSEN) are still under revision, therapists and teachers are finding it difficult to prepare these learners for appropriate employment after school. Even where systems in education are established, persons with learning disabilities face more challenges to enter employment [5]. This article reports on a unique career exploration programme for grade 11 learners at a school for learners with special educational needs in Gauteng, South Africa. It is a collaborative strategy between the learners, their parents, a teacher and the occupational therapists at the school. Two case studies are described to indicate the success of the program.

The Africa South America Intercontinental Teleconnection.

Cook, K. H.; Hsieh, J.-S.; Hagos, S. M.

2004-07-01

The influence of heating over Africa on the South American precipitation climatology, and the influence of South America on Africa, is examined through the application of GCM simulations with idealized boundary conditions and perpetual solstice (January and July) conditions.The presence of Africa is associated with a pronounced (up to 4 mm day-1) decrease in precipitation in Brazil's Nordeste region during austral summer. Low-level moisture divergence and dry-air advection associated with the downbranch of a Walker circulation induced by heating over southern Africa is amplified over the Nordeste due to the response of the land surface. The response is much smaller during austral winter due to differences in the heat source over Africa and a reduced sensitivity in the surface heat balance over tropical South America. Forcing from South America in January shifts the position of the South Indian convergence zone (SICZ) to the southwest over southern Africa in association with the formation of the South Atlantic convergence zone (SACZ). In July, a Rossby wave train generated over South America induces a response in the surface temperature of Africa that leads to stronger precipitation in central and western Africa.This study suggests a zonal mode of variability for South American and African circulation and precipitation fields. The resulting perturbations depend as much on land surface atmosphere interactions as on the direct forcing from the adjacent continent, and the mechanisms are highly nonlinear.

Lunar mosaic of 1500 Clementine images of the south polar region of the moon. The projection is orthographic, centered on the south pole. The Schrodinger Basin (320 km in diameter) is located in the lower right of the mosaic. Amundsen-Ganswindt is the more subdued circular basin between Schrodinger and the pole. The polar regions of the moon are of special interest because of the postulated occurrence of ice in permanently shadowed areas. The south pole is of greater interest because the area that remains in shadow is much larger than that at the north pole.

The politics of non-communicable diseases in the global South.

Reubi, David; Herrick, Clare; Brown, Tim

2016-05-01

In this paper, we explore the emergence of non-communicable diseases (NCDs) as an object of political concern in and for countries of the global South. While epidemiologists and public health practitioners and scholars have long expressed concern with the changing global distribution of the burden of NCDs, it is only in more recent years that the aetiology, politics and consequences of these shifts have become an object of critical social scientific enquiry. These shifts mark the starting point for this special issue on 'The Politics of NCDs in the Global South' and act as the basis for new, critical interventions in how we understand NCDs. In this paper, we aim not only to introduce and contextualise the six contributions that form this special issue, but also to identify and explore three themes - problematisation, care and culture - that index the main areas of analytical and empirical concern that have motivated analyses of NCDs in the global South and are central to critical engagement with their political contours.

Contamination Effects Due to Space Environmental Interactions

Science.gov (United States)

Chen, Philip T.; Paquin, Krista C. (Technical Monitor)

2001-01-01

Molecular and particulate contaminants are commonly generated from the orbital spacecraft operations that are under the influence of the space environment. Once generated, these contaminants may attach to the surfaces of the spacecraft or may remain in the vicinity of the spacecraft. In the event these contaminants come to rest on the surfaces of the spacecraft or situated in the line-of-sight of the observation path, they will create various degrees of contamination effect which may cause undesirable effects for normal spacecraft operations, There will be circumstances in which the spacecraft may be subjected to special space environment due to operational conditions. Interactions between contaminants and special space environment may alter or greatly increase the contamination effect due to the synergistic effect. This paper will address the various types of contamination generation on orbit, the general effects of the contamination on spacecraft systems, and the typical impacts on the spacecraft operations due to the contamination effect. In addition, this paper will explain the contamination effect induced by the space environment and will discuss the intensified contamination effect resulting from the synergistic effect with the special space environment.

Conservation of placentation during the tertiary radiation of mammals in South America.

Science.gov (United States)

Carter, Anthony Michael; Mess, Andrea Maria

2013-05-01

The eutherian placenta is considered to possess great plasticity, but it is not clear how this variation reflects adaptation to different ecological niches. Because South America was isolated for most of the Tertiary, it represents a natural laboratory to examine this question. We here describe placentation in three South American groups: Xenarthra have been part of the fauna from at least the mid-Paleocene whereas caviomorph rodents and Neotropical primates are each derived from a single founder that reached South America in the Eocene and Oligocene, respectively. The common ancestor of Xenarthra had a villous, haemochorial placenta, from which the labyrinthine, endotheliochorial placenta of sloths later evolved. Placentation in Caviomorpha follows an extraordinary stable pattern, characterized by a haemomonochorial, labyrinthine and highly lobed structure with specialized growing areas. This pattern was present before arrival of these rodents in South America and enabled a successful radiation especially during the spread of grasslands. Neotropical primates have haemochorial, trabecular placentas with a specialized maternal blood supply; a pattern that contrasts with that of Old World monkeys and may have been present in the founder generation on arrival in South America. In conclusion, there is a dichotomy within Xenarthra but otherwise the ancient South American mammals do not show much variation in principal placental characters. Thus, the successful radiation of these three groups, and their adaptation to diverse ecological niches, did not require substantial alterations in placentation.

Special event planning for the emergency manager.

Science.gov (United States)

Gaynor, Peter T

2009-11-01

In the domain of emergency management and homeland security there is a lack of a formal planning process at the local level when it comes to special event planning. The unique nature of special event planning demands an understanding of the planning process for both traditional and non-traditional planning partners. This understanding will make certain that local governments apply due diligence when planning for the safety of the public. This paper offers a practical roadmap for planning at the local level. It will address those 'special events' that are beyond routine local events but not of a sufficient scale to be granted National Special Security Event status. Due to the infrequency of 'special events' in most communities, it is imperative that deliberate planning takes place. Upon conclusion, the reader will be able to construct a planning process tailored to the needs of their community, guide both traditional and non-traditional planning partners through the planning process, determine priorities, explore alternatives, plan for contingencies, conduct a confirmation brief, facilitate operations and assemble an after-action report and improvement plan.

However, it has been proved quite challenging to adequately represent the aerosol spatial distribution and magnitude over this critical region in global models (Pan et al. 2014), with the surface concentrations, aerosol optical depth (AOD), and absorbing AOD (AAOD) significantly underestimated, especially in October-January when the agricultural waste burning and anthropogenic aerosol dominate over dust aerosol. In this study, we aim to investigate the causes for such discrepancy in winter by conducting sets of model experiments with NASA's GEOS-5 in terms of (1) spatial resolution, (2) emission amount, and (3) meteorological fields.

2015-03-01

Both mental and physical disorders can result in role limitation, such as 'days out of role', which have an important impact on national productivity losses. This paper analyses data from the South African Stress and Health Study (SASH) on the association of both mental and physical disorders with days out of role. Face-to-face interviews were conducted with a representative sample of 4,351 adult South Africans. The World Health Organization's Composite International Diagnostic Interview (WHO-CIDI) was used to assess the presence of 21 mental and physical disorders that were grouped into 10 disorder categories for the analysis: major depressive disorder, any anxiety disorders, any substance abuse disorders, headaches or migraine, arthritis, chronic pain, cardiovascular, respiratory, diabetes and digestive disorders. Multiple regression techniques were used to explore associations between individual disorders, comorbid conditions, and annual days spent out of role. The estimated societal effects of the disorders [population attributable risk proportion (PARP)] were obtained. The majority of respondents who reported a mental or physical disorder also reported another disorder (62.98 %). The average number of disorders reported by respondents who had at least one disorder was 2.3. Overall 12.4 % of respondents reported any days out of role due to mental or physical disorder. Anxiety disorders and depression were associated with highest days out of role (28.2 and 27.2, respectively) followed closely by arthritis and pain (24.7 and 21.7, respectively). Any mental disorder was associated with 23.6 days out of role, while any physical disorder was associated with 15.5 days out of role. Of the mental disorders, anxiety disorders had the highest PARP in relation to days out of role (9.0 %) followed by depression (4.8 %) and substance disorder (3.3. %). More than one-third (37.6 %) of days out of role are attributable to physical disorders and 16.1 % to mental

John R.U. Wilson

2017-03-01

Full Text Available South Africa has committed to producing a National Status Report on Biological Invasions by October 2017 and thereafter every three years. This will be the first status report at a national level specifically on biological invasions. As part of soliciting input, a workshop was held in May 2016 that led to this special issue of 19 papers in the journal Bothalia: African Biodiversity and Conservation. This editorial introduces the symposium, discusses the special issue and summarises how each contribution provides an estimate of ‘status’. Papers focus on key pathways, taxa, areas, and evaluations of interventions, specifically the movement of taxa between South Africa and neighbouring countries; the dispersal pathways of amphibians; a review of alien animals; a report on changes in the number and abundance of alien plants; in-depth reviews of the status of invasions for cacti, fishes, fungi and grasses; an assessment of the impact of widespread invasive plants on animals; reviews on invasions in municipalities, protected areas and subAntarctic Islands; assessments of the efficacy of biological control and other control programmes; and recommendations for how to deal with conflict species, to conduct scientific assessments and to improve risk assessments. The papers in this special issue confirm that South Africa is an excellent place to study invasions that can provide insights for understanding and managing invasions in other countries. Negative impacts seem to be largely precipitated by certain taxa (especially plants, whereas invasions by a number of other groups do not, yet, seem to have caused the widespread negative impacts felt in other countries. Although South Africa has effectively managed a few biological invasions (e.g. highly successful biological control of some invasive plants, the key challenge seems to be to establish and maintain a strong link between implementation, monitoring, reporting and planning.

The Tectonic Boundary Between Eastern Subbaisin and South-West Subbasin of the South China Sea Revealed from the Normalized Magnetic Source Strength

Science.gov (United States)

Guo, L.; Meng, X.

2014-12-01

The South China Sea (SCS), surrounded by the Eurasia, Pacific and India-Australia plates, is one of the largest marginal seas in the Western Pacific. It was formed by the interaction of the three plates and the seafloor spreading during Late Oligocene time to Early Miocene time. The boundary between Eastern Subbaisin and South-west Subbasin of the SCS has long been debated in the literature. Refining the boundary is one of the crucial tasks for correctly understanding the seafloor spreading model of the SCS. Due to few drills on the deep ocean basin of the SCS, magnetic data become important information for refining the boundary. However, the interpretation of magnetic data in the SCS suffers from the remanent magnetization of ocean crust as well as igneous rock and seamounts. The conventional reduction-to-pole anomalies at low latitudes usually neglect the remanent magnetization, making the interpretation incorrect. Here, we assembled high-resolution total magnetic intensity (TMI) data around the ocean basin of the SCS, and then did a special transformation of the TMI anomalies with a varying magnetic inclinations algorithm to obtain the normalized source strength (NSS). The NSS has advantage of insensitivity to remanent magnetization, benefitting correct interpretation. The NSS presents discriminative features from east to west in the ocean basin. The boundary of the discriminative features is clear and just ranges from the northeastern edge of the Zhongsha Islands running in the southeast direction to the northeastern edge of the Reed Bank. These imply that magnetic structure and tectonic features in the crust are discriminative between both sides of this boundary. It can be deduced that this boundary is the tectonic boundary between Eastern Subbaisin and South-west Subbasin.

Little is known about phylogeography of armadillo species native to southern South America. In this study we describe the phylogeography of the screaming hairy armadillo Chaetophractus vellerosus, discuss previous hypothesis about the origin of its disjunct distribution and propose an alternative one, based on novel information on genetic variability. Variation of partial sequences of mitochondrial DNA Control Region (CR) from 73 individuals from 23 localities were analyzed to carry out a phylogeographic analysis using neutrality tests, mismatch distribution, median-joining (MJ) network and paleontological records. We found 17 polymorphic sites resulting in 15 haplotypes. Two new geographic records that expand known distribution of the species are presented; one of them links the distributions of recently synonimized species C. nationi and C. vellerosus. Screaming hairy armadillo phylogeographic pattern can be addressed as category V of Avise: common widespread linages plus closely related lineages confined to one or a few nearby locales each. The older linages are distributed in the north-central area of the species distribution range in Argentina (i.e. ancestral area of distribution). C. vellerosus seems to be a low vagility species that expanded, and probably is expanding, its distribution range while presents signs of genetic structuring in central areas. To explain the disjunct distribution, a hypothesis of extinction of the species in intermediate areas due to quaternary climatic shift to more humid conditions was proposed. We offer an alternative explanation: long distance colonization, based on null genetic variability, paleontological record and evidence of alternance of cold/arid and temperate/humid climatic periods during the last million years in southern South America.

Assessment of South Pars Gas Field Subsidence Due To Gas Withdrawal

Directory of Open Access Journals (Sweden)

Akbar Ghazifard

2014-12-01

Full Text Available Withdrawal of oil and gas from reservoirs causes a decrease in pore pressure and an increase in effective stress which results to a reservoir compaction. Reservoir compaction will result in surface subsidence through the elastic response of the subsurface. Usually in order to determine the subsidence above a hydrocarbon field, the reservoir compaction must be first calculated and then the effect of this compaction on the surface should be modeled. The use of the uniaxial compaction theory is more prevalent and an accepted method for determining the amount of reservoir compaction. But despite of the reservoir compaction calculation method, there are many methods with different advantages and shortcomings for modeling of surface subsidence. In this study, a simple analytical method and semi‌-analytical methods (AEsubs software were used for modeling of the surface subsidence of the South Pars gas field at the end of the production period.

The eutherian placenta is considered to possess great plasticity, but it is not clear how this variation reflects adaptation to different ecological niches. Because South America was isolated for most of the Tertiary, it represents a natural laboratory to examine this question. We here describe...... placentation in three South American groups: Xenarthra have been part of the fauna from at least the mid-Paleocene whereas caviomorph rodents and Neotropical primates are each derived from a single founder that reached South America in the Eocene and Oligocene, respectively. The common ancestor of Xenarthra....... This pattern was present before arrival of these rodents in South America and enabled a successful radiation especially during the spread of grasslands. Neotropical primates have haemochorial, trabecular placentas with a specialized maternal blood supply; a pattern that contrasts with that of Old World monkeys...

Human Exposure Risk Assessment Due to Heavy Metals in Groundwater by Pollution Index and Multivariate Statistical Methods: A Case Study from South Africa

Directory of Open Access Journals (Sweden)

Vetrimurugan Elumalai

2017-04-01

Full Text Available Heavy metals in surface and groundwater were analysed and their sources were identified using multivariate statistical tools for two towns in South Africa. Human exposure risk through the drinking water pathway was also assessed. Electrical conductivity values showed that groundwater is desirable to permissible for drinking except for six locations. Concentration of aluminium, lead and nickel were above the permissible limit for drinking at all locations. Boron, cadmium, iron and manganese exceeded the limit at few locations. Heavy metal pollution index based on ten heavy metals indicated that 85% of the area had good quality water, but 15% was unsuitable. Human exposure dose through the drinking water pathway indicated no risk due to boron, nickel and zinc, moderate risk due to cadmium and lithium and high risk due to silver, copper, manganese and lead. Hazard quotients were high in all sampling locations for humans of all age groups, indicating that groundwater is unsuitable for drinking purposes. Highly polluted areas were located near the coast, close to industrial operations and at a landfill site representing human-induced pollution. Factor analysis identified the four major pollution sources as: (1 industries; (2 mining and related activities; (3 mixed sources- geogenic and anthropogenic and (4 fertilizer application.

The trade specialization of SANE: Evidence from manufacturing industries

Directory of Open Access Journals (Sweden)

Alessandrini, Michele

2010-06-01

Full Text Available This paper studies the evolution of the foreign trade specialization in manufacturing sectors of South Africa, Algeria, Nigeria and Egypt. These four countries, the so-called SANE, have recently been viewed as Africa's best chance of producing an economic bloc whose role for Africa might be comparable to that of the BRIC economies of Brazil, Russia, India and China for the world economy. Using data on trade flows since mid-1970s, the results show that the SANE group has experienced few changes in its trade structure, which is still based on low-technology and slow-growth world demand sectors. The degree of persistence in the specialization model is higher in the case of Algeria and Nigeria, where the dependence on products based on natural resources is stronger.

Biohydrogen production as a potential energy fuel in South Africa

Directory of Open Access Journals (Sweden)

P.T. Sekoai

2015-06-01

Full Text Available Biohydrogen production has captured increasing global attention due to it social, economic and environmental benefits. Over the past few years, energy demands have been growing significantly in South Africa due to rapid economic and population growth. The South African parastatal power supplier i.e. Electricity Supply Commission (ESKOM has been unable to meet the country’s escalating energy needs. As a result, there have been widespread and persistent power cuts throughout the country. This prompts an urgent need for exploration and implementation of clean and sustainable energy fuels like biohydrogen production in order to address this crisis. Therefore, this paper discusses the current global energy challenges in relation to South Africa’s problems. It then examines the feasibility of using biohydrogen production as a potential energy fuel in South Africa. Finally, it reviews the hydrogen-infrastructure development plans in the country.

Developing efficient and cost-effective eye care programmes for communities in Nigeria has been hampered by inadequate and inaccurate data on blindness and low vision. To determine the prevalence and causes of blindness and low vision among adults 50 years and older in South-Western Nigeria in order to develop viable eye care programme for the community. Twenty clusters of 60 subjects of age 50 years and older were selected by systematic random cluster sampling. Information was collected and ocular examinations were conducted on each consenting subject. Data were recorded in specially designed questionnaire and analysed using descriptive statistical methods. Out of the 1200 subjects enrolled for the study, 1183(98.6%) were interviewed and examined. Seventy five (6.3%)) of the 1183 subjects were bilaterally blind and 223(18.9%) had bilateral low vision according to WHO definition of blindness and low vision. Blindness was about 1.6 times commoner in men than women. Cataract, glaucoma and posterior segment disorders were major causes of bilateral blindness. Bilateral low vision was mainly due to cataract, refractive errors and posterior segment disorders. The prevalence of blindness and low vision in this study population was high. The main causes are avoidable. Elimination of avoidable blindness and low vision calls for attention and commitment from government and eye care workers in South Western Nigeria.

Urban Ecology in Cape Town: South African Comparisons and Reflections

Directory of Open Access Journals (Sweden)

Sarel S. Cilliers

2012-09-01

Full Text Available Little urban ecological research has been done in South Africa. The papers in the Ecology and Society special feature Urban Ecological and Social-Ecological Research in the City of Cape Town make, therefore, an important contribution to the development of urban ecology locally and globally. Different approaches have been used in the study of urban ecology of different urban areas in South Africa. Cape Town is situated in a biodiversity hotspot and is the only South African city which includes a national park. As a result the urban ecological studies were mainly driven by urban nature conservation concerns. In other cities such as Durban, open space planning and environmental management were the major issues which focused ecological studies on urban areas whereas other studies of urban areas in the Eastern Cape and North-West provinces included private and public open spaces and man-made habitats. We reflect on the Cape Town studies in a South African context and highlight conservation of biodiversity, protection of ecosystem services, management of control measures, and the conflict between humans and nature. A brief synthesis has also been given of South African urban ecological research in general.

Large differences in terms of incidence and mortality due to gallbladder cancer (GBC) have been reported worldwide. Moreover, it seems that GBC has unique characteristics in South America. We surveyed the literature looking for information about the epidemiology, basic and translational research, and clinical trials performed in South America in order to critically analyze the magnitude of this health problem in the region. Compared to other geographic areas, age-standardized mortality rates (ASMR) for GBC in women are very high, particularly in many western areas of South America. Genetic, as well as dietary and environmental factors likely contribute to the pathogenesis of this disease in the area. Compared to other regions the profile of abnormalities of key genes such as KRAS and TP53 in GBC seems to slightly differ in South America, while the clinical behavior appears to be similar with a median overall survival (OS) of 6.5 to 8 months in advanced GBC. In contrast to Europe and USA, prophylactic cholecystectomy is a common practice in western areas of South America. GBC particularly affects women in South America, and represents a significant public health problem. It appears to have peculiarities that pose an urgent need for additional research aimed to discover risk factors, molecular events associated with its development and new treatment options for this lethal disease.

Rising South Korea : A Minor Player or a Regional Power?

Recent trends in economic burden of acute myocardial infarction in South Korea.

Directory of Open Access Journals (Sweden)

Hyeyoung Seo

Full Text Available In 2010, ischemic heart disease was the leading cause of disability-adjusted life-years (DALYs worldwide. More specially, the prevalence of acute myocardial infarctions (AMI is increasing in the aged population as mortality decreases; South Korea is no exception. This study aims to examine the economic burden of AMI in the Korean population between 2007 and 2012. AMI-related costs were assessed from a societal perspective. A prevalence-based cost-of-illness framework was used for this analysis. The subjects included all South Koreans with AMI-related ICD-10 codes (I21, I22, I23, I25.0, and I25.1. Data on direct (medical and non-medical costs and indirect (productivity loss due to AMI-associated morbidity and mortality costs were collected from the Korean National Health Insurance Service's claims data. The human capital approach was used to calculate indirect costs. The total estimated cost of AMI in 2012 was $1,177,649,323 USD. The majority (52% of this amount was made up of medical costs, followed by productivity losses due to mortality and morbidity (42% of annual cost. Although the total cost declined by approximately 18% compared to 2007 ($1,427,643,854 USD, the cost of AMI in the over 60 age group amounted to 47% of the total cost of AMI in 2012. AMI led to a high economic burden in 2012. This study, which identified not only the size, but also the trends of AMI-related costs, will provide information to evaluate effects of governmental health projects and the effective allocation of public research funds.

[Adaptation experiences in South Korea of men defecting from North Korea].

Science.gov (United States)

Kim, Kyoung Mi; Kim, Miyoung

2013-06-01

The study was done to explore meanings and essence of the experience in South Korea of men defectors from North Korea. Data were collected from March, 2011 to May, 2012, through in-depth interviews with ten men defectors. Data analysis was conducted using the process of hermeneutic phenomenological reflection. Eight essential themes were extracted; 'buoyant expectation for a new life', 'feeling guilty about family left behind in North Korea', 'inability to become acclimatized due to communication difficulties', 'inability to socialize with South Koreans due to different lifestyles', 'finding strength through trustworthy acquaintances', 'continuing reconciliation with oneself while trying to assimilate into South Korean culture', 'self-realization of one's original self', and 'continuing to feel out the possibility of a future in South Korea'. The findings indicate that North Korean men who defect to South Korea shape their identity through three phases: forming self-image during escape from North Korea, trying to become accustomed to South Korean society, and finding their own identity by self-realization of their original self. Eventually, the whole process enables them to recover their identity, to feel a sense of belonging, and to discover possibilities for a better future.

State Agencies of Special Nature in Colombia

Directory of Open Access Journals (Sweden)

María Clara Garrido

2017-01-01

Full Text Available With the latest reform of the Colombian Public Administration (2011 to 2013, the use of the term “National Agency” increases, in order to designate new administrative structures aimed to produce results and effectively manage public resources. Among the newly created administration, some structures were referred as “state agencies of special nature”, due to their alleged technical and specialized character. Through a comparison that encompasses functional and institutional aspects, this paper demonstrates that the expression “state agencies of special nature” does not establish a new category of public entities, different from other national agencies and administrative bodies listed in Act 489 of 1998.

Health tourism in South Africa: opportunities and possibilities

Directory of Open Access Journals (Sweden)

Unathi Sonwabile Henama

2014-01-01

Full Text Available The tourism industry is one industry that has grown in leaps and bound since the watershed moment in 1994. Mining and manufacturing have declined their share of gross domestic product contribution, whilst tourism has been a perennial growth sector. The growth of tourism has resulted in tourism becoming a priority sector by government and the private sector. Tourism creates jobs, attracts investment, foreign exchange and diversifies the economy. Health tourism can be regarded within the definition of special interest tourism, which is regarded as ‘’new tourism’’. The private healthcare system in South Africa is world class, and the growth of tourism has led to synergies being formed for the development of medical tourism in South Africa. The paper reviews health and medical tourism secondary literature to present an argument for the development of the industry, and the identification of obstacles to the growth of health tourism. There is paucity of academic gaze on medical tourism and the secondary research will present certain findings that will be of benefit to the health tourism industry in South Africa.

Anecdotal evidence from clinical data in Johannesburg suggests that there is a high burden of dental caries among children with special health care needs (CSHCN) in Johannesburg. To determine the prevalence of dental caries and Unmet Treatment Needs in children with cerebral palsy, hearing, learning and mental disabilities attending special needs schools in Johannesburg and to compare these with data from the National Children's Oral Health Survey (NCOHS) METHODS: This cross-sectional analytical study comprised of 882 children attending five special needs schools in Johannesburg. Stratified randomised sampling of the participating schools was done and the schools were stratified by disability. Caries status was recorded via the dmft/DMFT index using WHO criteria and guidelines. The mean age of the participants was 10.5 years; with a caries prevalence of 27.55% and 33.56% in the primary and permanent dentition respectively. The highest unmet treatment need of 100% was found in the permanent dentition of the hearing impaired group followed by 90.77% in the primary dentition of the cerebral palsy group. In general no significant difference was found when the dmft/DMFT for CSHCN and NCOHS were compared except in the hearing impaired age groups four to five and six (both primary dentition) where significantly higher dmft scores (3.58 vs. 2.4; 3.85 vs. 2.9; p special health care needs had lower caries prevalence compared with the general population and higher unmet treatment needs regardless of the type of disability.

Public health foodborne illness case study during a Special Operations Forces deployment to South America.

Science.gov (United States)

McCown, Michael; Grzeszak, Benjamin

2010-01-01

Although many public health articles have been published detailing foodborne illness outbreaks, a medical literature search revealed no articles that detail a case study or a specific response of a deployed U.S. military unit to a potential foodborne illness. This article describes a recent public health case study of a U.S. Special Operations Forces (SOF) team sickened while deployed to South America. It highlights public health factors which may affect U.S. personnel deployed or serving overseas and may serve as a guide for a deployed SOF medic to reference in response to a potential food- or waterborne illness outbreak. Eight food samples and five water samples were collected. The food samples were obtained from the host nation kitchen that provided food to the SOF team. The water samples were collected from the kitchen as well as from multiple sites on the host nation base. These samples were packaged in sterile containers, stored at appropriate temperatures, and submitted to a U.S. Army diagnostic laboratory for analysis. Laboratory results confirmed the presence of elevated aerobic plate counts (APCs) in the food prepared by the host nation and consumed by the SOF team. High APCs in food are the primary indicator of improper sanitation of food preparation surfaces and utensils. This case study concluded that poor kitchen sanitation, improper food storage, preparation, and/or holding were the probable conditions that led to the team?s symptoms. These results emphasize the importance of ensuring safe food and water for U.S. personnel serving overseas, especially in a deployment or combat setting. Contaminated food and/or water will negatively impact the health and availability of forces, which may lead to mission failure. The SOF medic must respond to potential outbreaks and be able to (1) critically inspect food preparation areas and accurately advise commanders in order to correct deficiencies and (2) perform food/water surveillance testing consistently

Population Structure of mtDNA Variation due to Pleistocene Fluctuations in the South American Maned Wolf (Chrysocyon brachyurus, Illiger, 1815): Management Units for Conservation.

2015-01-01

The maned wolf (Chrysocyon brachyurus) is one of the largest South American canids, and conservation across this charismatic carnivore's large range is presently hampered by a lack of knowledge about possible natural subdivisions which could influence the population's viability. To elucidate the phylogeographic patterns and demographic history of the species, we used 2 mtDNA markers (D-loop and cytochrome b) from 87 individuals collected throughout their range, in Argentina, Bolivia, Brazil, and Uruguay. We found moderate levels of haplotype and nucleotide diversity, and the 14 D-loop haplotypes were closely related. Genetic structure results revealed 4 groups, and when coupled with model inferences from a coalescent analysis, suggested that maned wolves have undergone demographic fluctuations due to changes in climate and habitat during the Pleistocene glaciation period approximately 24000 years before present (YBP). This genetic signature points to an event that occurred within the timing estimated for the start of the contraction of the Cerrado around 50000 YBP. Our results reveal a genetic signature of population size expansion followed by contraction during Pleistocene interglaciations, which had similar impacts on other South American mammals. The 4 groups should for now be considered management units, within which future monitoring efforts should be conducted independently. © The American Genetic Association 2015. All rights reserved.

The pollination ecology of an assemblage of grassland asclepiads in South Africa.

Science.gov (United States)

Ollerton, Jeff; Johnson, Steven D; Cranmer, Louise; Kellie, Sam

2003-12-01

The KwaZulu-Natal region of South Africa hosts a large diversity of asclepiads (Apocynaceae: Asclepiadoideae), many of which are endemic to the area. The asclepiads are of particular interest because of their characteristically highly evolved floral morphology. During 3 months of fieldwork (November 2000 to January 2001) the flower visitors and pollinators to an assemblage of nine asclepiads at an upland grassland site were studied. These observations were augmented by laboratory studies of flower morphology (including scanning electron microscopy) and flower colour (using a spectrometer). Two of the specialized pollination systems that were documented are new to the asclepiads: fruit chafer pollination and pompilid wasp pollination. The latter is almost unique in the angiosperms. Taxa possessing these specific pollination systems cluster together in multidimensional phenotype space, suggesting that there has been convergent evolution in response to similar selection to attract identical pollinators. Pollination niche breadth varied from the very specialized species, with only one pollinator, to the more generalized, with up to ten pollinators. Pollinator sharing by the specialized taxa does not appear to have resulted in niche differentiation in terms of the temporal or spatial dimensions, or with regards to placement of pollinaria. Nestedness analysis of the data set showed that there was predictability and structure to the pattern of plant-pollinator interactions, with generalist insects visiting specialized plants and vice versa. The research has shown that there is still much to be learned about plant-pollinator interactions in areas of high plant diversity such as South Africa.

Lavinia Lupu

2012-08-01

Full Text Available Transitions from Soviet authoritarianism and planned economies to democracy and market economies have not been successfully completed in any of the three states from South Caucasus. This region continues to be characterized by high instability and insecurity due the absence of solutions to the protracted or „frozen” conflicts between Armenia and Azerbaijan – over the territory of Nagorno-Karabakh – and between Georgia and Russia – over the breakaway regions of South Ossetia and Abkhazia. Finding common ground upon which all parties can agree has proven to be an impossible task. Protracted or „frozen” conflicts present a challenge for the stability and security of South Caucasus.

Aspect-Driven Changes in Slope Stability Due to Ecohydrologic Feedbacks

Seasonally integrated variation in insolation drives feedbacks among evapotranspiration, soil moisture, weathering, and erosion that lead to pronounced contrasts in slope angles and vegetation on north and south-facing hillslopes. Spatial variations in insolation associated with north-south contrasts in topographic aspect leads to corresponding variation in local microclimates and ecohydrologic regimes that, in turn, impact spatial patterns of weathering and erosion, ultimately impacting slope angles on north and south-facing slopes. Aspect-sensitive environments appear to be poised on a balance point between ecohydrologic systems, and may be especially susceptible to climate change. In the semi-arid Colorado Plateau of northeastern Arizona, cliffs often form on south-facing slopes where soil moisture is insufficient for weathering of clay-cemented sandstone that is susceptible to hydration. In contrast, cliffs are rare on northerly slopes, which are dominated by mantles of weathered sandstone and colluvium (Burnett et al., 2008, doi:10.1029/2007JF000789). However, in semi-arid regions of the Idaho Batholith, preliminary results indicate some north-facing slopes are significantly steeper than south-facing slopes. We hypothesize that in semi-arid areas with observable increases in vegetation on north vs. south-facing slopes, north-facing slopes will be steeper due to increased soil cohesion, increased capture of wind-borne loess due to vegetative wind-baffling, and differences in the type and magnitude of erosive processes. In moister areas where aspect does not visibly control vegetation type and density, differences in slope angles with aspect should not be observed. We investigate tectonically quiescent regions of the mostly-homogenous granodioritic Idaho Batholith to locate areas sensitive to aspect-induced variations in insolation and compare slope characteristics on north and south-facing slopes.

Human consumption of a vagrant South American Fur Seal Arctocephalus australis (Carnivora: Otariidae in Brazil

Directory of Open Access Journals (Sweden)

S. Siciliano

2016-04-01

Full Text Available The South American Fur Seal Arctocephalus australis is one of the most widely distributed South American otariid species. In Brazil, during austral winter months specimens of A. australis are regularly found along the Rio Grande do Sul and Santa Catarina coasts. Occasionally, vagrants have been recorded along the southeastern coast but rarely moves north of Rio de Janeiro, at 23°S. On 01 May 2015, fishermen noticed in the surf zone an unidentified large animal in Ilhéus, Bahia, northeastern Brazil. Severely wounded, it was still alive when first spotted. Numerous shark bites were observed in the rostrum and flippers, the peduncle was severely lacerated and the intestines were protruding. The specimen was identified as an adult of South American Fur Seal based on the combination of the characteristic coloration of the pelage, head shape, body size, the relatively large eye size, and mainly due to the pronounced three cusped teeth in post canines. Fishermen decided to butcher the carcass and share the meat among their companions. The present record, however, is of special concern as human consumption South American Fur Seal seems to be unusual in Brazil. Pieces of meat were shared among fishermen. In addition, small pieces of blubber were used as bait in the local shark long-line fishery. Consumption of an injured and presumably weak marine mammal carcass points to an increasing risk of contact between potentially harmful viruses, bacteria and fungi and humans. This note represents an alert to public health specialists and wildlife authorities in Brazil. It calls the urgency of an outreach campaign advertising to the potential risks of ingesting bushmeat either from land or aquatic sources.

Nemutandani, M S; Adedoja, D; Nevhuhlwi, D

2013-11-01

To determine the prevalence of dental caries among disabled individuals attending special schools in Vhembe districts. A cross-sectional descriptive study was conducted from January to June 2012 among disabled individuals receiving special care in four specialised schools of Vhembe District. The research protocol had been approved by the Ethics Committee of the University of Limpopo, Polokwane Campus. Informed consent was obtained from the parents of the participants and from the respective school principals. Oral health examinations took place at the school under natural light, with participants seated on an ordinary chair/wheelchair. Dental caries examinations were carried out, using a mirror and wooden spatula in accordance with World Health Organisation (WHO) criteria and methods. Decayed, missing and filled primary and permanent teeth (dmft, DMFT) were recorded. All disabled individuals who were available during a screening period, were included. Those who were not available, as well as those whose health conditions could be compromised by dental examinations, were excluded. The number of decayed teeth ranged from 0-7 in children below 6 years, 0-12 in children below 11 years; and 0-17 among young adults. The mean decay scores and the numbers of missing teeth increased with age. Only 3 (0.04%) individuals had dental fillings. The mean dmft score of children under 6 years was 5.51 (+/- 2.1), ranging from zero to 8. The mean DMFT's of the 11-18 and 19 years and older groups were 7.38 (+/- 3.22) and 10.24 (+/- 2.97) respectively. Disabled individuals exhibited higher caries prevalence and unmet dental needs than the same age general population in Limpopo. Preventive measures and dental treatment should be considered urgent requirements at special needs schools in the Vhembe District.

Physical activity among South Asian women: a systematic, mixed-methods review.

Babakus, Whitney S; Thompson, Janice L

2012-12-20

The objective of this systematic mixed-methods review is to assess what is currently known about the levels of physical activity (PA) and sedentary time (ST) and to contextualize these behaviors among South Asian women with an immigrant background. A systematic search of the literature was conducted using combinations of the key words PA, ST, South Asian, and immigrant. A mixed-methods approach was used to analyze and synthesize all evidence, both quantitative and qualitative. Twenty-six quantitative and twelve qualitative studies were identified as meeting the inclusion criteria. Studies quantifying PA and ST among South Asian women showed low levels of PA compared with South Asian men and with white European comparison populations. However making valid comparisons between studies was challenging due to a lack of standardized PA measurement. The majority of studies indicated that South Asian women did not meet recommended amounts of PA for health benefits. Few studies assessed ST. Themes emerging from qualitative studies included cultural and structural barriers to PA, faith and education as facilitators, and a lack of understanding of the recommended amounts of PA and its benefits among South Asian women. Quantitative and qualitative evidence indicate that South Asian women do not perform the recommended level of PA for health benefits. Both types of studies suffer from limitations due to methods of data collection. More research should be dedicated to standardizing objective PA measurement and to understanding how to utilize the resources of the individuals and communities to increase PA levels and overall health of South Asian women.

Lozano-Alarcón, F; Bradley, G A; Houser, B S; Visvesvara, G S

1997-05-01

Naegleria fowleri, Acanthamoeba spp., and Balamuthia mandrillaris are known to cause fatal central nervous system (CNS) disease in human beings. N. fowleri causes acute, fulminating primary amebic meningoencephalitis (PAM), which generally leads to death within 10 days. Acanthamoeba spp. and B. mandrillaris cause chronic granulomatous amebic encephalitis, which may last for 8 weeks. Acanthamoeba spp. and B. mandrillaris also cause CNS disease in animals. N. fowleri, however, has been described only in human beings. This report is the first of PAM in an animal, a South American tapir. Dry cough, lethargy, and coma developed in the animal, and its condition progressed to death. At necropsy, lesions were seen in the cerebrum, cerebellum, and lungs. The CNS had severe, suppurative meningoencephalitis with many neutrophils, fibrin, plasma cells, and amebas. Amebas were 6.5 microns to 9 microns in diameter and had a nucleus containing a large nucleolus. Amebas in the sections reacted with a monoclonal antibody specific for N. fowleri in the immunofluorescent assay and appeared bright green.

Quivers For Special Fuel Rods-Disposal Of Special Fuel Rods In CASTOR V Casks

International Nuclear Information System (INIS)

Bannani, Amin; Cebula, Wojciech; Buchmuller, Olga; Huggenberg, Roland; Helmut Kuhl

2015-01-01

While GNS casks of the CASTOR family are a suitable means to transfer fuel assemblies (FA) from the NPP to an interim dry storage site, Germanys phase-out of nuclear energy has triggered the demand for an additional solution to dispose of special fuel rods (SFR), normally remaining in the fuel pond until the final shutdown of the NPP. SFR are fuel rods that had to be removed from fuel assemblies mainly due to their special condition, e. g. damages in the cladding of the fuel rods which may have occurred during reactor operations. SFR are usually stored in the spent fuel pond after they are removed from the FA. The quiver for special fuel rods features a robust yet simple design, with a high mechanical stability, a reliable leak-tightness and large safety margins for future requirements on safety analysis. The quiver for special fuel rods can be easily adapted to a large variety of different damaged fuel rods and tailored to the specific need of the customer. The quiver for special fuel rods is adaptable e.g. in length and diameter for use in other types of transport and storage casks and is applicable in other countries as well. The overall concept presented here is a first of its kind solution for the disposal of SFRs via Castor V-casks. This provides an important precondition in achieving the status 'free from nuclear fuel' of the shut down German NPPs

Single-country time-series analysis cannot be done without addressing endogeneity between output and inequality. South Africa has been under-researched in this area due to a lack of data. Recent data released by the Presidency of South Africa makes such analysis possible. Besides, the use of a single inequality index in such a multiracial societ...

The claims handling process of engineering insurance in South Africa

Directory of Open Access Journals (Sweden)

I.C. de Beer

2015-05-01

Full Text Available Due to technological developments, the complicated world of engineering and its associated products are continuously becoming more specialized. Short-term insurers provide engineering insurance to enable the owners and operators of engineering assets to combat the negative impact of the associated risks. It is, however, a huge challenge to the insurers of engineering insurance to manage the particular risks against the background of technological enhancement. The skills gap in the short-term insurance market and the engineering environment may be the main factor which inhibits the growth of the engineering insurance market. The objective of this research embodies the improvement of financial decision-making concerning the claims handling process of engineering insurance. Secondary as well as primary data were necessary to achieve the stated objective. The secondary data provided the background of the research and enabled the researchers to compile a questionnaire for the empirical survey. The questionnaire and a cover letter were sent to the top 10 short-term insurers in South Africa that are providing engineering insurance. Their perceptions should provide guidelines to other short-term insurers who are engaged in engineering insurance, as they are regarded as the market leaders of engineering insurance in South Africa. The empirical results of this research focus on the importance of various claims handling factors when assessing the claims handling process of engineering insurance, the problem areas in the claims handling process concerned, as well as how often the stipulations of engineering insurance policies are adjusted to take the claims handling factors into account.

A conservative estimate of the wind resource indicates that approximately 5% to 6% of the South African energy demands can be supplied from wind. However the low cost of electricity due to the abundance of cheap coal has made it difficult to justify the use of grid connected wind turbines. As with other countries where wind energy is now a part of the total energy package, South Africa will also have to go through a process of wind energy having to prove itself as a viable option while at the same time have a cost disadvantage.

Marketing of irradiated commodities in South Africa

Energy Technology Data Exchange (ETDEWEB)

Du Plessis, T A; Stevens, R C.B.

1985-01-01

Although the industrial exploitation of radiation processing in the medical and allied fields has been successfully marketed and applied for the past two decades in South Africa, the introduction of food radurisation on an industrial level adds a completely new dimension to the marketing of this processing technique. Extensive research into the use of radiation for the treatment of various foodstuffs has been carried out by the Nuclear Development Corporation of South Africa for more than a decade, resulting in South Africa being one of the first countries where a commercial irradiator dedicated to this branch of radiation processing, was established. The marketing of this process is especially difficult due to the emotive aspects associated with radiation and man's sensitive reaction to anything pertaining to his food. This situation was made even more difficult by the general public's apprehension towards nuclear activities throughout the world. Details are given of the steps taken in South Africa to transform the unfavourable public image associated with the process. The approach proved to be very successful and greatly assisted in creating a climate whereby the public in South Africa today generally has a favourable attitude towards the radurisation of foodstuffs.

landforms, including some broad areas of consistent topographic patterns that indicate the occurrence of simple erosional processes acting upon fairly uniform bedrock. Very smooth plateaus here are remnants of landforms most likely developed under geologic and environmental conditions much different than those present today. Fractures paralleling the coast are likely related to the opening of the Atlantic Ocean as South America drifted away from Africa, starting about 130 million years ago.To the southwest, broad lowlands host the Gran Chaco and Pampas regions. The depositional Gran Chaco drainages run almost exclusively from west to east from the Andes Mountains to the western edge of the Brazilian Highlands as a result of the much greater sediment supply from the Andes. Geologic processes on the Pampas are much more diverse, with stream erosion, stream deposition, subsidence, and wind processes all evident, even at the one-kilometer resolution shown here.Further south, Patagonia also displays these geologic processes plus more prominent volcanic features, including bumpy mesas, which are lava plateaus with small (and some large) volcanic cones. At its southern tip, of South America breaks into islands that include Tierra del Fuego and the Straits of Magellan.This anaglyph was created by deriving a shaded relief image from the SRTM data, draping it back over the SRTM elevation model, and then generating two differing perspectives, one for each eye. Illumination is from the north (top). 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.Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000.

1996-01-01

Between the mid 1960s and 1975, state legislatures, the federal courts, and the U.S. Congress spelled out strong educational rights for children with disabilities. Forty-five state legislatures passed laws mandating, encouraging, and/or funding special education programs. Federal courts, interpreting the equal protection and due process guarantees of the Fourteenth Amendment to the U.S. Constitution, ruled that schools could not discriminate on the basis of disability and that parents had due process rights related to their children's schooling. Congress, in legislation now retitled the Individuals with Disabilities Education Act (IDEA), laid out detailed procedural protections regarding eligibility for special educational services, parental rights, individualized education programs (IEPs), the requirement that children be served in the least restrictive environment, and the need to provide related (noneducational) services. Decisions on instructional matters such as curricula and the elements of the IEP remain the province of local and state authorities. Advocates for students with disabilities have continually sought separate (categorical) funding for special education services. Current movements toward block grants rather than categorical programs and toward greater inclusion of special education students in general education classrooms raise concerns in some quarters about whether students with disabilities will continue to have full access to the special services they need. While the cost of special services may be an unexpressed criterion in many decisions made by school districts, nowhere does the IDEA explicitly allow cost to be considered. Where a service is necessary for an individual child, cost considerations would not allow a school district to escape its obligations to the child. However, in instances where more than one appropriate configuration of services is available to meet a child's needs, the school district may be allowed to consider the cost

Recognition in Programmes for Children with Special Needs

Directory of Open Access Journals (Sweden)

Marjeta Šmid

2016-09-01

Full Text Available The purpose of this article is to examine the factors that affect the inclusion of pupils in programmes for children with special needs from the perspective of the theory of recognition. The concept of recognition, which includes three aspects of social justice (economic, cultural and political, argues that the institutional arrangements that prevent ‘parity of participation’ in the school social life of the children with special needs are affected not only by economic distribution but also by the patterns of cultural values. A review of the literature shows that the arrangements of education of children with special needs are influenced primarily by the patterns of cultural values of capability and inferiority, as well as stereotypical images of children with special needs. Due to the significant emphasis on learning skills for academic knowledge and grades, less attention is dedicated to factors of recognition and representational character, making it impossible to improve some meaningful elements of inclusion. Any participation of pupils in activities, the voices of the children, visibility of the children due to achievements and the problems of arbitrariness in determining boundaries between programmes are some such elements. Moreover, aided by theories, the actions that could contribute to better inclusion are reviewed. An effective approach to changes would be the creation of transformative conditions for the recognition and balancing of redistribution, recognition, and representation.

History of National Economic System Formation in the Republic of South Africa

Full Text Available The article analyses specific historic features of formation of agrarian and industrial sectors of Republic of South Africa since the establishment of Cape Colony. These features resulted from much earlier colonization of South Africa in comparison with other Sub-Saharan African countries on the one hand and from a large-scale influx of Europeans to the South Africa on the other hand. The two most important of these specific features are the following. First. Contrary to other countries of Sub-Saharan Africa development of the agrarian sector of Republic of South Africa was based on private property and western technologies from the start. Second. The sector is not divided into «African» and «European» sub-sectors, and South-African agricultural produce has always been oriented to both: external and internal markets. Development of industrial sector of Republic of South Africa started with creation of extractive industries, namely: extraction of diamonds and of gold. The authors specifically emphasize the role of gold extraction which grace to its effect of multiplicator opened the way for industrial revolution in the South of Africa. Development of manufacturing was mainly based on import-substitution. The article argues that there were several stages of import-substitution and analyses their outcomes. The authors point out to the special importance of import-substitution during the period of I World War and II World War.

Are plants used for skin care in South Africa fully explored?

South Africa is an important focal point of botanical diversity, and although many plant species have been used since ancient times in ethnomedicine, only a few species have hitherto been fully investigated scientifically. A large proportion of the South African population use traditional medicines for their physical and psychological health needs. Many medicinal plants have recently gained popularity as ingredient in cosmetic formulations based on their ethnomedicinal values and many cosmetic products sold in stores are of natural origin. The present review discusses the ethnopharmacological values, pharmacological and toxicological evidence of 117 plant species grown in South Africa, which are used traditionally for skin care purposes. Special focus was on their traditional use for many skin disorders in order to identify their therapeutic potential, the state of ethnopharmacological knowledge and special emphasis has been on areas which require further research. The information regarding all 117 plant species mentioned was extracted from Sci-Finder, Science direct, Medline and Google Scholar. All the available relevant data for medicinal plants was collated from literature review articles from the 19th century to early 2013. The extracts from different parts of plants exhibited significant pharmacological properties, proving significant skin care potentials. Special emphasis was on those plant species which still need further exploration and these have been documented separately. Despite the immense use of plants in ethnomedicine for skin care, limited research has been done on the activity of the crude extracts and very little on the active constituents. Consequently, almost 35 out of the 117 species are totally unexplored in the area of skin care. This investigation would be of interest to a broad readership including those researchers working in this field. The plant species namely: Greyia flanaganii, Sideroxylon inerme, Sclerocarya birrea, Calodendrum

2007-01-01

Several South-American native societies snuff psychoactive seeds in magic-religious rituals since ancient times. To describe archeological, historical and ethnographical evidences regarding the ritual use of vilca or yopo (Anadenanthera sp). Anadenanthera seeds were used in South America 3,000 years ago. Archeological studies found vilca seeds in funerary tombs from 1,000 BC in the north of Chile and Argentina; ceramics and snuff tubes were found in San Pedro de Atacama archeological sites from the same data, and in Tiwanaku ceremonial center in Bolivian Altiplano. Today, Anadenanthera sp is used by several native groups in Orinoco basin, where is known as yopo, and in the Brazilian and Colombian Amazon. Hallucinogenic effect is due to the presence of methyl-tryptamine derivatives. Most snuff is prepared from the roasted and powdered seeds, vegetable ash and/or lime obtained from shells. Archeological and ethnographical data suggest that vilca was used and is still used by native shamans as a sacred seed in South America, due to its hallucinogenic effects.

van Wyk, Christa

2010-06-01

In terms of South African legislation, all health research on human participants must be submitted to an accredited research ethics committee for independent ethics review. Health research covers a broad spectrum of research, including clinical trials. This article sets out the ethical-legal framework for the functioning and composition of such committees. It also deals with the newly created National Health Research Ethics Council, which registers and audits health research ethics committees. Special attention is given to the conduct of clinical trials. In conclusion, it is submitted that the National Health Act, the Draft Regulations Relating to Research on Human Subjects, and two sets of ethical guidelines adopted by the Department of Health provide a much needed and coherent ethical-legal framework for research in South Africa.

SADCC: challenging the "South African connection.".

Science.gov (United States)

Liebenow, J G

1982-01-01

The Southern African Development Coordination Conference (SADCC) which unites 9 states with a combined population of 60 million, has as its objective the task of promoting economic development and realizing economic independence. In many respects the strain of neocolonialism that Southern Africa faces at this time is even more virulent than that facing West, Central, and East Africa. In the latter regions the surrender of political authority by colonial administrators frequently left the commercial, agricultural, and industrial interests of the European powers in continued control of the economies of the former colonies. The fate of economic development plans was determined by situations and decisions made in places distant from the African continent. In the case of Southern Africa, the withdrawal or expulsion of European colonialists has found whites in neighboring South Africa most eager to step into the economic breech. For most of the Southern African states this variant strain of the neocolonial virus creates a dual problem: the independent states acting separately have been no match for South Africa; and the acquiescence of independent African states in forging economic links with South Africa has impeded the liberation efforts of Africans in Namibia and the Republic of South Africa. Discussion focus turns to the challenges that confront SADCC; transport as the most significant factor accounting for the dependency of SADCC states upon South Africa; the role of minerals in dependency; other aspects of dependency; South Africa's proposed Constellation of States; the origins and objectives of SADCC; and dollars and donors. SADCC planning for economic liberation has been conducted against the background of a counterproposal advanced by South Africa's government, which put the Republic at the center of an expanded network of economic linkages within the entire southern African region. While being formally rejected, the Constellation of States scheme does have

Context: Many coaches, parents, and children believe that the best way to develop elite athletes is for them to participate in only 1 sport from an early age and to play it year-round. However, emerging evidence to the contrary indicates that efforts to specialize in 1 sport may reduce opportunities for all children to participate in a diverse year-round sports season and can lead to lost development of lifetime sports skills. Early sports specialization may also reduce motor skill development and ongoing participation in games and sports as a lifestyle choice. The purpose of this review is to employ the current literature to provide evidence-based alternative strategies that may help to optimize opportunities for all aspiring young athletes to maximize their health, fitness, and sports performance. Evidence Acquisition: Nonsystematic review with critical appraisal of existing literature. Study Design: Clinical review. Level of Evidence: Level 4. Conclusion: Based on the current evidence, parents and educators should help provide opportunities for free unstructured play to improve motor skill development and youth should be encouraged to participate in a variety of sports during their growing years to influence the development of diverse motor skills. For those children who do choose to specialize in a single sport, periods of intense training and specialized sport activities should be closely monitored for indicators of burnout, overuse injury, or potential decrements in performance due to overtraining. Last, the evidence indicates that all youth should be involved in periodized strength and conditioning (eg, integrative neuromuscular training) to help them prepare for the demands of competitive sport participation, and youth who specialize in a single sport should plan periods of isolated and focused integrative neuromuscular training to enhance diverse motor skill development and reduce injury risk factors.

2015-08-01

Full Text Available This article presents a comparison of central debates in South African labor sociology in the1970s and the contemporary era. I argue that scholars can break through impasses in currentlabor sociology debates by reviving attention to the land-labor-livelihood (LLL connections thatinspired theoretical advancements in the South African literature of the 1970s. After anintroduction and definition of LLL connections, the paper analyzes an exemplary work of thelabor literature of the 1970s, giving special attention to the way in which the LLL focus shapedthe questions asked by the authors. The article proceeds to a review of central debates from thecurrent labor literature, which focuses primarily on issues of the labor movement. It is arguedthat this focus on movements has limited the scope of labor scholarship, resulting in an impassein South African labor debates. An emerging literature that renews attention to the LLLconnections is proposed as a model for moving beyond this impasse. I close the article bydiscussing the implications for this review of South African literature for global laborscholarship.

Teaching medical ethics to undergraduate students in post-apartheid South Africa, 2003 2006.

Science.gov (United States)

Moodley, Keymanthri

2007-11-01

The apartheid ideology in South Africa had a pervasive influence on all levels of education including medical undergraduate training. The role of the health sector in human rights abuses during the apartheid era was highlighted in 1997 during the Truth and Reconciliation Commission hearings. The Health Professions Council of South Africa (HPCSA) subsequently realised the importance of medical ethics education and encouraged the introduction of such teaching in all medical schools in the country. Curricular reform at the University of Stellenbosch in 1999 presented an unparalleled opportunity to formally introduce ethics teaching to undergraduate students. This paper outlines the introduction of a medical ethics programme at the Faculty of Health Sciences from 2003 to 2006, with special emphasis on the challenges encountered. It remains one of the most comprehensive undergraduate medical ethics programmes in South Africa. However, there is scope for expanding the curricular time allocated to medical ethics. Integrating the curriculum both horizontally and vertically is imperative. Implementing a core curriculum for all medical schools in South Africa would significantly enhance the goals of medical education in the country.

To estimate over-diagnosis due to population-based mammography screening using a lead time adjustment approach, with lead time measures based on symptomatic cancers only. Women aged 40-84 in 1989-2009 in South Australia eligible for mammography screening. Numbers of observed and expected breast cancer cases were compared, after adjustment for lead time. Lead time effects were modelled using age-specific estimates of lead time (derived from interval cancer rates and predicted background incidence, using maximum likelihood methods) and screening sensitivity, projected background breast cancer incidence rates (in the absence of screening), and proportions screened, by age and calendar year. Lead time estimates were 12, 26, 43 and 53 months, for women aged 40-49, 50-59, 60-69 and 70-79 respectively. Background incidence rates were estimated to have increased by 0.9% and 1.2% per year for invasive and all breast cancer. Over-diagnosis among women aged 40-84 was estimated at 7.9% (0.1-12.0%) for invasive cases and 12.0% (5.7-15.4%) when including ductal carcinoma in-situ (DCIS). We estimated 8% over-diagnosis for invasive breast cancer and 12% inclusive of DCIS cancers due to mammography screening among women aged 40-84. These estimates may overstate the extent of over-diagnosis if the increasing prevalence of breast cancer risk factors has led to higher background incidence than projected. © The Author(s) 2015.

For the last three years, a new ESA Data User Element (DUE) project had focussed on creating improved knowledge about the Essential Climate Variable Biomass. The main purpose of the DUE GlobBiomass project is to better characterize and to reduce uncertainties of AGB estimates by developing an innovative synergistic mapping approach in five regional sites (Sweden, Poland, Mexico, Kalimantan, South Africa) for the epochs 2005, 2010 and 2015 and for one global map for the year 2010. The project team includes leading Earth Observation experts of Europe and is linked through Partnership Agreements with further national bodies from Brazil, Canada, China, Russia and South Africa. GlobBiomass has demonstrated how EO observation data can be integrated with in situ measurements and ecological understanding to provide improved biomass estimates that can be effectively exploited by users. The target users had mainly be drawn from the climate and carbon cycle modelling communities and included users concerned with carbon emissions and uptake due to biomass changes within initiatives such as REDD+. GlobBiomass provided a harmonised structure that can be exploited to address user needs for biomass information, but will be capable of being progressively refined as new data and methods become available. This presentation will give an overview of the technical prerequisites and final results of the GlobBiomass project.

Full Text Available Objective: The Brunel Mood Scale (BRUMS has proved useful to assess mood states in a range of clinical settings. Its local utility is restricted by the lack of normative data from South Africa. This paper presents preliminary normative data for the use of the BRUMS in the South African health care setting. Method: Participants (N=2200, ranging from 18 to 59 years, employed in the public sector, and were recruited during routine occupational health surveillance, completed the 24-item self-report BRUMS. They came from all South African race and language groups, and from all nine provinces. Results: Significant differences were found between the scores of women and men, and their results are reported separately. Due to the language dependant nature of the BRUMS, results are also reported separately for respondents with English as first language, and those who have other South African languages as mother tongue. Norm tables with T-scores are presented for the full sample, and per gender X language groups. Conclusion: This study presents normative data for a sample of educated and employed South Africans from various backgrounds. Its brevity, and provisionally language friendly nature makes it a useful measure for screening psychological distress in the SA clinical health care context.

The South Central Climate Science Center was established by the U.S. Department of the Interior in 2012 to increase understanding of climate change and coordinate an effective response to climate-change effects on Native American tribes and natural and cultural resources that the Department manages. The eight regional Climate Science Centers of the U.S. Department of the Interior work closely with natural-resource management agencies, university researchers, and others such as tribes and private landowners on climate-change issues. The relatively large number of Native Americans in the south central United States and their special knowledge of changing ecosystems make working with tribes and tribal members on climate-change issues particularly important in this part of the Nation. This circular describes priorities of the South Central Climate Science Center and provides information about resources available from Climate Science Centers and partner agencies regarding climate change. The circular also describes how this Climate Science Center, tribes and tribal members, and others can collaborate to minimize potential harmful effects of climate change on human society and our surrounding ecosystems.

Logistic regression models were fit for children who enrolled in early intervention/early childhood special education services with a primary disability diagnosis of developmental delay and changed primary disability diagnosis before third grade (n=5076). Odds of enrollment in future special education were greater in children with a change in primary disability diagnosis after the age of five in comparison to children that had a change in primary disability diagnosis before the age of five, while adjusting for demographic characteristics (adjusted odds ratio: 2.37, 95% CI 1.92, 2.92). Results suggest that children who are diagnosed with a developmental delay and exit early childhood special education due to maximum age of eligibility are more likely to enroll in special education compared to children without a gap in service access. Gaps in service access during early development are associated with the need for supportive services later on in life. Copyright © 2017 Elsevier Ltd. All rights reserved.

Special labour protection of certain employee categories

Jovanović Predrag P.

2015-01-01

Full Text Available The employed women, the youth and the disabled enjoy special protection at work. Such a protection is stipulated by legal documents of the international and our labour law. The protection of women is provided for three reasons: the need to emancipate women and their equalisation with all the rights as men have; the protection due to women's physical constitution; the protection due to women's role in biological reproduction of the population (pregnancy, childbirth and maternity. The youth enjoy protection due to their young age and accordingly their adequate psychophysical and mental maturity. By youth, children and people under 18 are implied, because the minimum age for entering into labour relations is 15. This refers to the minors that are exposed to the adverse effect of the working conditions where certain more damaging and more difficult jobs can leave severe and lethal consequences on the youth's development. The disabled are people with a reduced working ability, and thus the odds of them finding a suitable job and keep it are significantly reduced, as opposed to other people. Therefore, the reasons of their special protection lie in the need to bring them to equal terms as others to achieve their socio-economic rights at work and connected with work.

South Korea aspires to become a major nuclear supplier in the world nuclear market. There is no doubt that South Korea has great potential to fulfill these aspirations. South Korea is well positioned in terms of competitiveness, market relationships, institutional capability, ability to deliver, and commitment to nonproliferation values. As a mercantilist state, South Korea hopes to capitalize on its close relationships with transnational nuclear corporations in this endeavor. It hopes to participate in two- or three-way joint ventures---especially with the American firms that have traditionally predominated in the South Korean domestic nuclear business---to market their nuclear wares abroad. This paper is divided into four parts. The first section describes South Korea's intent to become a nuclear supplier in the 1990s. It delineates the networks of prior transactions and relationships that South Korea may use to penetrate export markets. The second section reviews South Korea's nuclear export potential, particularly its technological acquisitions from the domestic nuclear program. These capabilities will determine the rate at which South Korea can enter specific nuclear markets. The third section describes the institutional framework in South Korea for the review and approval of nuclear exports

Teaching medical ethics to undergraduate students in post‐apartheid South Africa, 2003–2006

Moodley, Keymanthri

2007-01-01

The apartheid ideology in South Africa had a pervasive influence on all levels of education including medical undergraduate training. The role of the health sector in human rights abuses during the apartheid era was highlighted in 1997 during the Truth and Reconciliation Commission hearings. The Health Professions Council of South Africa (HPCSA) subsequently realised the importance of medical ethics education and encouraged the introduction of such teaching in all medical schools in the country. Curricular reform at the University of Stellenbosch in 1999 presented an unparalleled opportunity to formally introduce ethics teaching to undergraduate students. This paper outlines the introduction of a medical ethics programme at the Faculty of Health Sciences from 2003 to 2006, with special emphasis on the challenges encountered. It remains one of the most comprehensive undergraduate medical ethics programmes in South Africa. However, there is scope for expanding the curricular time allocated to medical ethics. Integrating the curriculum both horizontally and vertically is imperative. Implementing a core curriculum for all medical schools in South Africa would significantly enhance the goals of medical education in the country. PMID:17971474

Lack of government intervention in South Africa’s mining industry has worsened conflicts associated with limited water resources. With the advent of democracy, new legislation demands that all South African citizens have the right to a clean, safe environment, including access to potable water, and that the country develop in a sustainable manner. But conflict remains due to the historical partnership between the government and the mining industry, as well as due to cumulative impacts associa...

Factors Contributing to Sexual Violence at Selected Schools for Learners with Mild Intellectual Disability in South Africa.

Nyokangi, Doris; Phasha, Nareadi

2016-05-01

This paper reports part of the findings of a study which exposed sexual violence in schools for learners with mild intellectual disability in South Africa. Special attention was paid on factors contributing to such a problem. Data were collected using focus groups and individual interviews with 16 learners with mild intellectual disability at two special schools in South Africa. This was followed by individual interviews with the school nurse and social worker, and an analysis of schools' books of incidents. Factors contributing to sexual violence at schools for learners with mild intellectual disability included: (i) peer pressure, (ii) concealment of reported incidents of sexual violence, (iii) unsupervised areas linked to schools and (iv) arranged relationships. The following suggestions are put forth: (i) awareness programmes, (ii) sensitization of teachers about the consequences and prevention of sexual violence, (iii) boundaries within which the arranged relationship occurs, (iv) intensification of sexuality education and (v) supervision around the school premises. © 2015 John Wiley & Sons Ltd.

The early history of research funding in South Africa: From the Research Grant Board to the FRD

Full Text Available The South African government has a long tradition of supporting research at public higher education institutions. Such support commenced in the early 20th century, although the exact nature of the support at that time is poorly documented. The oldest research funding model in the country was agency funding, which started as early as 1911 through the Royal Society of South Africa. A few years later, in 1918, a more coordinated funding body called the Research Grant Board (RGB was established in the Union of South Africa. The RGB offered competitive funding to individual academics in the natural and physical sciences. The human sciences were only supported much later with the establishment of the Council for Educational and Social Research in 1929. Here we review the history of research funding in South Africa, with a special focus on the work of the RGB between 1918 and 1938.

Kundu, Nilay; Shukla, Ashish; Trivedi, Sandip P.

2016-01-01

We derive the general Ward identities for scale and special conformal transformations in theories of single field inflation. Our analysis is model independent and based on symmetry considerations alone. The identities we obtain are valid to all orders in the slow roll expansion. For special conformal transformations, the Ward identities include a term which is non-linear in the fields that arises due to a compensating spatial reparametrization. Some observational consequences are also discussed.

Exploring the epistemology of transdisciplinarity in public policy and administration in South Africa

Directory of Open Access Journals (Sweden)

Emeka A. Ndaguba

2017-06-01

Full Text Available This article seeks to address and direct future research collaboration in public policy and administration from a transdisciplinary perspective in South Africa, by answering three major questions: Firstly, how can public administration be understood from a transdisciplinary perspective? To demonstrate the development of public administration vis-a-vis trends in contemporary public policy and administration in South Africa? And establish the scope for future collaborative research in public policy and administration from a transdisciplinarity perspective in South Africa? This article uses themes in the qualitative realm to provide answers to the research aims: two special editions of Future, Transdisciplinary Manifesto and over 100 journal articles were read and scanned to provide evidence for the arguments in this article. It concludes that the need for transdisciplinarity in public policy and administration cannot be undermined or overlooked as a result of depleting strategies, theories, models and frameworks in resolving complex society quagmires from a disciplinary or interdisciplinary nomenclature.

LANDSCAPE-ECOLOGICAL PLANNING OF THE COASTAL ZONE OF SOUTH-WEST CRIMEA

V. N. Danekina

2017-01-01

Full Text Available The article is devoted to the application of methods of landscape planning in order to maintain the sustainable state of the coastal south-western part of the Crimean peninsula. There are many protected landscapes in this territory, including reserves and other specially protected landscapes. However, the network of such specially protected natural resources can not fully satisfy the resources they consume and simultaneously maintain a favorable ecological situation in the region. The results of studies of the prospects and prerequisites for the formation and preservation of the landscape-ecological framework of the South-Western Crimea have been presented. Various groups of factors that negatively affect the ecological state of the region are analyzed, among them construction in coastal protective bands, recreational digression of soils and vegetation, pollution with industrial wastewater, illegal sand sampling, etc. Assessment of nature use structures has shown that the existing system needs landscape-ecological justification and planning. The structure of the landscape-ecological framework of the South-Western Crimea has been developed. Its elements have been identified, which contain natural “cores” subject to special protection, ecological corridors and buffer zones. In the course of the study, a mapping of the landscapeecological planning organization of the coastal territory of the Crimean coast has been carried out. The map-scheme shows the elements of the landscape-ecological framework, landscape zones and belts and types of anthropogenic landscapes. In the conditions of limited economic development of the territory, the landscape-ecological framework must include transformed anthropogenic landscapes. Landscape planning should be carried out taking into account regional features of the Black Sea coast, for this purpose the article gives a brief description of the landscape diversity and stability of landscape geosystems.

The importance and significance of peace studies with special reference to South Africa’s political-security role in Africa

Directory of Open Access Journals (Sweden)

T. Neethling

2006-07-01

Full Text Available The origins of peace studies as an academic field of inquiry could be traced to the late 1940s and the field has been developing considerably since then. Currently, scholars at various tertiary institutions over the world are involved in using their academic skills to educate students about the causes of wars and violent conflict while pointing out various alternatives to these phenomena. Peace studies in the South African and broader African context are certainly of great significance and importance. After all, the gripping and devastating violence that manifested in African countries such as Liberia, Sierra Leone, Sudan, Burundi, Rwanda, the DRC, Somalia, Angola, the Comoros and many other conflict-stricken areas warrant scholarly attention with a view to better understanding the causes, dynamics and effects of such conflict. By means of this understanding the conflict could be addressed through mechanisms of conflict resolution and peace building could be promoted. Furthermore, the South African Government’s progressive military involvement in international peace missions in recent years is far more than an issue of mere military concern. It is a matter of great political interest and significance. Being supportive of the need for peace studies in the curricula of South African universities (and African universities in general, this article argues that South African students should be exposed to a rich and comprehensive literature on the search for international peace and security; of how to understand and deal with the causes of large-scale conflict and violence; and how these could be curtailed and resolved − literature which informs scholarly discussions and research in many centres and places of education, training and peace building.

The improvement of nuclear safety regulation : American, European, Japanese, and South Korean experiences

International Nuclear Information System (INIS)

Cho, Byung Sun

2005-01-01

Key concepts in South Korean nuclear safety regulation are safety and risk. Nuclear regulation in South Korea has required reactor designs and safeguards that reduce the risk of a major accident to less than one in a million reactor-years-a risk supposedly low enough to be acceptable. To data, in South Korean nuclear safety regulation has involved the establishment of many technical standards to enable administration enforcement. In scientific lawsuits in which the legal issue is the validity of specialized technical standards that are used for judge whether a particular nuclear power plant is to be licensed, the concept of uncertainty law is often raised with regard to what extent the examination and judgement by the judicial power affects a discretion made by the administrative office. In other words, the safety standards for nuclear power plants has been adapted as a form of the scientific technical standards widely under the idea of uncertainty law. Thus, the improvement of nuclear safety regulation in South Korea seems to depend on the rational lawmaking and a reasonable, judicial examination of the scientific standards on nuclear safety

Beyond rhetoric: South-South collaboration for REDD+

Global debates about reducing emissions from deforestation and forest degradation, and promoting conservation, sustainable forest management and enhancement of forest carbon stocks (REDD+) emphasise the need for strategies to build on existing knowledge. In one example of South-South collaboration to do just this, IIED has helped facilitate a Mozambique-Brazil partnership to share expertise and create a unique REDD+ working group. The initiative provides key lessons for other countries contemplating South-South collaboration on REDD+, including the need for charismatic champions, continuity in government representation, and integration across sectors.

The challenge of nuclear proliferation control in South Asia

Prevention of nuclear weapon proliferation in South Asia is considered a a difficult challenge. The paper discusses the difficulties met in implementing the nuclear non-proliferation policy due to numerous disputes concerning China, North and South Korea, India and Pakistan, and the countries of former Soviet Union. Matters preventing proliferation are mentioned as well as obstacles to non-proliferation proposing that decisions whether voluntary or, eventually, compulsory would have to be consistently enforced by the Security Council, if states are to rely upon those methods for their security

Specialized due diligence called for on Medicare/Medicaid issues in health care acquisitions.

Science.gov (United States)

Vernaglia, Lawrence W; Herman, Dimitry S; Ziegler, Rachel Schneller

2005-01-01

A careful and comprehensive due diligence process is mission-critical to the success of any complex business acquisition. In heavily regulated industries such as health care, a buyer's greatest risks can arise from practices relating to Medicare, Medicaid, and other governmental payors. In particular, the rules of "successor liability" for the seller's sins are fundamentally different in a health care transaction than in other traditional corporate acquisitions. These liabilities may attach not only for expected business debts, but also for unexpected and draconian penalties available as remedies under the False Claims Act, Civil Money Penalties Law, and a number of other enforcement authorities. In addition, because critical cash flow depends on accepting certain liabilities of the seller, in the health care context these risks may be voluntarily assumed. Thus, here, due diligence is not just about finding "deal breakers," it is about helping the provider's management team understand the financial and risk-management components of the transaction at hand.

Modeling Future Land Use Scenarios in South Korea: Applying the IPCC Special Report on Emissions Scenarios and the SLEUTH Model on a Local Scale

Han, Haejin; Hwang, YunSeop; Ha, Sung Ryong; Kim, Byung Sik

2015-05-01

This study developed three scenarios of future land use/land cover on a local level for the Kyung-An River Basin and its vicinity in South Korea at a 30-m resolution based on the two scenario families of the Intergovernmental Panel on Climate Change (IPCC) Special Report Emissions Scenarios (SRES): A2 and B1, as well as a business-as-usual scenario. The IPCC SRES A2 and B1 were used to define future local development patterns and associated land use change. We quantified the population-driven demand for urban land use for each qualitative storyline and allocated the urban demand in geographic space using the SLEUTH model. The model results demonstrate the possible land use/land cover change scenarios for the years from 2000 to 2070 by examining the broad narrative of each SRES within the context of a local setting, such as the Kyoungan River Basin, constructing narratives of local development shifts and modeling a set of `best guess' approximations of the future land use conditions in the study area. This study found substantial differences in demands and patterns of land use changes among the scenarios, indicating compact development patterns under the SRES B1 compared to the rapid and dispersed development under the SRES A2.

The stranded individualizer under compressed modernity: South Korean women in individualization without individualism.

Science.gov (United States)

Kyung-Sup, Chang; Min-Young, Song

2010-09-01

South Korean families have functioned as a highly effective receptacle for the country's highly compressed conditions of modernity and late modernity. It is as much due to the success of South Korean families as an engine of compressed modernity as due to their failure that they have become functionally overloaded and socially risk-ridden. Such familial burdens and risks are particularly onerous to South Korean women because of the fundamentally gender-based structure of family relations and duties that has in part been recycled from the Confucian past and in part manufactured under industrial capitalism. Under these complicated conditions, South Korean women have had to dramatically restructure their family relations and duties as well as their individual life choices. Furthermore, under the most recent condition of what Beck calls second modernity, other institutions of modernity, such as the state, industrial economy, firms, unions, schools, and welfare systems, have become increasingly ineffective in helping to alleviate such (gender-based) familial burdens and dilemmas. As a result South Korean women have experienced dramatic changes in marriage patterns, fertility, family relations, etc. South Korean women's individualization has thereby taken place primarily as a matter of practicality rather than ideational change. A brief analysis of the situation in the neighbouring societies of Japan and Taiwan reinforces the conclusion that individualization without individualism, particularly among women, is a region-wide phenomenon in East Asia. © London School of Economics and Political Science 2010.

IMF sector behavior which has previously been estimated from the geomagnetic data at Godhavn is confirmed by study of the data at South Pole for 1959--1970 with the same estimation technique, taking the difference between northern and southern hemispheres into consideration. A method to improve (about 18%) the agreement between assigned and actual sector structures by study of the data at the two stations is suggested. Geomagnetic disturbance effects on sector estimation are discussed, and reversed sector effects in winter are given special emphasis

Insight into American tourists’ experiences with weather in South Africa

Directory of Open Access Journals (Sweden)

Giddy Julia K.

2017-12-01

Full Text Available Weather and climate are often important factors determining the success of a tourism destination and resultant satisfaction among tourists. This is particularly true for South Africa due the predominance of outdoor tourist attractions. Increasing numbers of international tourists have visited South Africa since the fall of apartheid, particularly those from the United States (U.S., which is an important market for South African tourism. Therefore, this paper seeks to examine a sample of American tourists’ experience with day-to-day weather and climatic conditions in South Africa. The results show that although respondents did not feel that climatic conditions were an important factor in motivations to visit the country, the day-to-day weather did often impact the enjoyment of their visit. Most notably, weather controlled their ability to participate in outdoor activities. In correlating accounts of unpleasant weather conditions with the meteorological records, a close association emerged, particularly for excessively high temperatures. This indicates that the experiences of American tourists are an accurate indication of climatic unsuitability for tourism, which poses threats to the South African outdoor tourism sector.

VIRAL HEPATITIS A TO E IN SOUTH MEDITERRANEAN COUNTRIES

Directory of Open Access Journals (Sweden)

Sanaa M. Kamal

2010-02-01

Full Text Available Viral hepatitis represents an important health problem in the South Mediterranean countries, Egypt, Libya, Tunisia, Algeria and Morocco.  Emerging natural history and epidemiological information reveal differences in the overall epidemiology, risk factors and modes of transmission of viral hepatitis A, B, C, D, E infections in the South Mediterranean region. The differences in the in incidence and prevalence of viral hepatitis across North African countries is attributed to variations in health care  and sanitation standards, risk factors and immunization strategies. The active continuous population movement through travel, tourism and migration from and to the South Mediterranean countries contribute to the spread of infections due to hepatitis viruses across borders leading to outbreaks and emergence of new patterns of infection or introduction of uncommon genotypes in other countries, particularly in Europe.

Southeast Asia-South America interregionalism: a complement to bilateralism

Directory of Open Access Journals (Sweden)

M. Florencia Rubiolo

2016-09-01

Full Text Available Inter-state relations between the countries of South America and Southeast Asia (SEA have blossomed in the past 15 years, arousing the interest of a growing number of academics. Their interregional relations, on the other hand, have been less well examined, due, probably, to the fact that their development remains incipient, as well as sporadic and poorly institutionalised. The starting point for this work is the premise that in the case of non-central regions this level of connection complements and works as a feedback mechanism for bilateral links and encourages State-State, State-region and region-region rapprochement. It introduces notions of South American regionalism and centres on concepts related to non-triadic interregionalism in the initiatives between South America and SEA since 1999.

Everson, C. S.; Bond, W. J.; Moncrieff, G. R.; Everson, T. M.

2015-12-01

There is currently little information in South Africa concerning the influence of terrestrial ecosystems on biosphere-atmosphere interactions and their impact on the earth system. Climate modellers require data on energy exchanges between the soil-plant-atmosphere continuum to develop surface models of carbon, energy and water to scale up from the different biomes in South Africa, to regional and, ultimately, global scales. Atmospheric exchanges of South African biomes (ecosystems) are important due to the large and varied pant diversity they represent. The important ecosystem services (including water) delivered by these natural systems and their potential role in the long-term CO2 uptake from the atmosphere and carbon storage is a key gap in South African research. South Africa is already a water-scarce country so the predicted impacts of climate change on water resources are likely to have devastating effects. It is against this diminishing water supply that the South African government must develop innovative investments in water technologies and infrastructure to mitigate the impacts of growing water shortages due to climate change. The Department of Science and Technology of South Africa is planning a multi-million rand investment in long-term ecological infrastructure with a focus on carbon, water and energy. The terrestrial programme will comprise six to seven landscape-scale 'climate change observatories', some in urban and agricultural situations, with eddy covariance flux towers for carbon water and energy measurements, regular remote sensing, for the long-term collection of environmental, ecological and social data. The South African flux network measurement programme aims to become a key role player in the assessment of the consequences of rapid land use change and future impacts of climate change both regionally and internationally. Key words: flux towers, eddy co-variance, carbon, water and energy

The influence of South Korean energy policy on OPEC oil exports

International Nuclear Information System (INIS)

Almansoori, Ali

2014-01-01

South Korea is the fifth top oil importer worldwide with 64% of its oil coming from OPEC member countries. Over the last 30 years, South Korea accounted for a rapid increase in energy use. This in turn led South Korea to be totally dependent on oil imports. Due to this increase, South Korea has been experiencing drastic changes in its energy system which could potentially impact its dependence on OPEC oil import. External and internal factors have forced South Korea to change its energy strategy and targets. These targets would be achieved by reducing its energy intensity and utilizing electricity and renewable energies in order to reduce its dependence on oil consumption. “Low Carbon, Green Growth” is one policy along with many other energy policies developed by South Korea for reducing greenhouse gases, thus this policy is receiving a remarkable attention today. These national policies along with other international ones are needed to mitigate greenhouse gas emissions and promote other green initiatives. This study puts emphasis on these policies as well as uses them to predict the future energy profile of South Korea and how these policies will impact on oil imports from OPEC member countries. - Highlights: • Analyze energy policy of South Korea and its energy profiles. • Study the factors that affect South Korea to change its energy strategy and targets. • Analyze the implications of South Korean energy policy on oil imports from OPEC. • South Korea will continue importing oil from OPEC countries for the next decade

2014-04-01

As the body of scientific knowledge in a discipline increases, there is pressure for specialization. Fields spawn subfields that then become entities in themselves that promote further specialization. The process by which scientists join specialized groups has remarkable similarities to the guild system of the middle ages. The advantages of specialization of science include efficiency, the establishment of normative standards, and the potential for greater rigor in experimental research. However, specialization also carries risks of monopoly, monotony, and isolation. The current tendency to judge scientific work by the impact factor of the journal in which it is published may have roots in overspecialization, as scientists are less able to critically evaluate work outside their field than before. Scientists in particular define themselves through group identity and adopt practices that conform to the expectations and dynamics of such groups. As part of our continuing analysis of issues confronting contemporary science, we analyze the emergence and consequences of specialization in science, with a particular emphasis on microbiology, a field highly vulnerable to balkanization along microbial phylogenetic boundaries, and suggest that specialization carries significant costs. We propose measures to mitigate the detrimental effects of scientific specialism.

Spatial effects, sampling errors, and task specialization in the honey bee.

Johnson, B R

2010-05-01

Task allocation patterns should depend on the spatial distribution of work within the nest, variation in task demand, and the movement patterns of workers, however, relatively little research has focused on these topics. This study uses a spatially explicit agent based model to determine whether such factors alone can generate biases in task performance at the individual level in the honey bees, Apis mellifera. Specialization (bias in task performance) is shown to result from strong sampling error due to localized task demand, relatively slow moving workers relative to nest size, and strong spatial variation in task demand. To date, specialization has been primarily interpreted with the response threshold concept, which is focused on intrinsic (typically genotypic) differences between workers. Response threshold variation and sampling error due to spatial effects are not mutually exclusive, however, and this study suggests that both contribute to patterns of task bias at the individual level. While spatial effects are strong enough to explain some documented cases of specialization; they are relatively short term and not explanatory for long term cases of specialization. In general, this study suggests that the spatial layout of tasks and fluctuations in their demand must be explicitly controlled for in studies focused on identifying genotypic specialists.

Slag, a by-product from the iron and steel industry, has a range of applications within construction and is used in wastewater treatment. Historically considered a waste material, little consideration was given to the environmental impacts of its disposal. South Gare (a Site of Special Scientific Interest) located at the mouth of the Tees estuary, UK, formed on slag deposits used to create a sea wall and make the land behind permanent. Over time, ponds formed in depressions with the water chemistry, being significantly impacted by the slag deposits. Calcium levels reached 504 mg/L, nitrate 49.0 mg/L and sulphate 1,698 mg/L. These levels were also reflected in the composition of the sediment. pH (5.10-9.90) and electrical conductivity (2,710-3,598 µS/cm) were variable but often notably high. Pb, Cu and Cd were not present within the water, whilst Zn ranged from 0.027 to 0.37 mg/L. Heavy metal levels were higher in surface sediments. Zinc was most dominant (174.3-1,310.2 mg/L) followed by Pb (9.9-431 mg/L), Cu (8.4-41.8 mg/L) and Cd (0.4-1.1 mg/L). A sediment core provided a historical overview of the ponds. The ponds were unfavourable for aquatic biodiversity and unsuitable for drinking water abstraction.

A Statist Political Economy and High Demand for Education in South Korea

Directory of Open Access Journals (Sweden)

Ki Su Kim

1999-06-01

Full Text Available In the 1998 academic year, 84 percent of South Korea's high school "leavers" entered a university or college while almost all children went up to high schools. This is to say, South Korea is now moving into a new age of universal higher education. Even so, competition for university entrance remains intense. What is here interesting is South Koreans' unusually high demand for education. In this article, I criticize the existing cultural and socio-economic interpretations of the phenomenon. Instead, I explore a new interpretation by critically referring to the recent political economy debate on South Korea's state-society/market relationship. In my interpretation, the unusually high demand for education is largely due to the powerful South Korean state's losing flexibility in the management of its "developmental" policies. For this, I blame the traditional "personalist ethic" which still prevails as the

Background The World Health Organization (WHO) aims to reduce tuberculosis (TB) deaths by 95% by 2035; tracking progress requires accurate measurement of TB mortality. International Classification of Diseases (ICD) codes do not differentiate between HIV-associated TB and HIV more generally. Verbal autopsy (VA) is used to estimate cause of death (CoD) patterns but has mostly been validated against a suboptimal gold standard for HIV and TB. This study, conducted among HIV-positive adults, aimed to estimate the accuracy of VA in ascertaining TB and HIV CoD when compared to a reference standard derived from a variety of clinical sources including, in some, minimally-invasive autopsy (MIA). Methods and findings Decedents were enrolled into a trial of empirical TB treatment or a cohort exploring diagnostic algorithms for TB in South Africa. The WHO 2012 instrument was used; VA CoD were assigned using physician-certified VA (PCVA), InterVA-4, and SmartVA-Analyze. Reference CoD were assigned using MIA, research, and health facility data, as available. 259 VAs were completed: 147 (57%) decedents were female; median age was 39 (interquartile range [IQR] 33–47) years and CD4 count 51 (IQR 22–102) cells/μL. Compared to reference CoD that included MIA (n = 34), VA underestimated mortality due to HIV/AIDS (94% reference, 74% PCVA, 47% InterVA-4, and 41% SmartVA-Analyze; chance-corrected concordance [CCC] 0.71, 0.42, and 0.31, respectively) and HIV-associated TB (41% reference, 32% PCVA; CCC 0.23). For individual decedents, all VA methods agreed poorly with reference CoD that did not include MIA (n = 259; overall CCC 0.14, 0.06, and 0.15 for PCVA, InterVA-4, and SmartVA-Analyze); agreement was better at population level (cause-specific mortality fraction accuracy 0.78, 0.61, and 0.57, for the three methods, respectively). Conclusions Current VA methods underestimate mortality due to HIV-associated TB. ICD and VA methods need modifications that allow for more specific

The trade interchange between Latin America and South Korea: The impact of technological development in the trade integration

Directory of Open Access Journals (Sweden)

Humberto Merritt Tapia

2010-05-01

Full Text Available Trade relations between Latin America and the Republic of Korea started in the early sixties, but only after the beginning of the new century have become more dynamic, especially for the Asian nation. Behind the Korean export boom is the governmental thrust to science and technology, which has resulted in the production of goods with higher added value. The pattern of trade specialization followed by South Korea has allowed it to become one of the leading exporting nations of high technology goods in the world. On the other hand, Latin American nations have also enjoyed a remarkable growth in exports in the last decade, although their exporting profile contrast with that of Korea because their exports tend to be mainly primary products with low added value and some semi-finished goods . The pattern of specialization in Latin America is explained by its provision of vast natural resources, giving it a comparative advantage in world commodity markets. Unfortunately these advantages have not translated into sustained industrial developments throughout the region. In this context, the purpose of this paper is to illustrate the trade trends between South Korea and Latin America in the last ten years in an attempt to understand the reasons behind the asymmetries in trade flows that have been set in this period. The underlying assumption is that the commercial relationship between both parties depends on the pattern of specialization emerged in recent times and responds to the institutional policies implemented by both South Korea and by Latin American nations. The case of Mexico is highlighted because it is getting historic deficits with the Asian nation.

The specialist physician's approach to rheumatoid arthritis in South Africa.

Bester, Frederik C J; Bosch, Fredricka J; van Rensburg, Barend J Jansen

2016-03-01

Rheumatoid arthritis (RA) is expected to increase in Africa and South Africa. Due to the low numbers of rheumatologists in South Africa, specialist physicians also have to care for patients with RA. Furthermore several new developments have taken place in recent years which improved the management and outcome of RA. Classification criteria were updated, assessment follow-up tools were refined and above all, several new biological disease-modifying anti-rheumatic drugs were developed. Therefore it is imperative for specialist physicians to update themselves with the newest developments in the management of RA. This article provides an overview of the newest developments in the management of RA in the South African context. This approach may well apply to countries with similar specialist to patient ratios and disease profiles.

Workshop for coordinating South Carolina`s pre-college systemic initiatives

1997-03-26

The goal of the South Carolina Statewide Systemic Initiative (SC SSI) is to provide quality and effective learning experiences in science and mathematics to all people of South Carolina by affecting systemic change. To accomplish this goal, South Carolina must: (1) coordinate actions among many partners for science and mathematics change; (2) place the instruments of change into the hands of the effectors of change - teachers and schools; and (3) galvanize the support of policy makers, parents, and local communities for change. The SC SSI proposes to establish a network of 13 regional mathematics and science HUBs. The central idea of this plan is the accumulation of Teacher Leaders at each HUB who are prepared in special Curriculum Leadership Institutes to assist other teachers and schools. The HUB becomes a regional nexus for delivering services to schools who request assistance by matching schools with Teacher Leaders. Other initiatives such as the use of new student performance assessments, the integration of instructional technologies into the curriculum, a pilot preservice program, and Family Math and Family Science will be bundled together through the Teacher Leaders in the HUBs. Concurrent policy changes at the state level in teacher and administrator certification and recertification requirements, school regulations and accountability, and the student performance assessment system will enable teachers and schools to support instructional practices that model South Carolina`s new state Curriculum Frameworks in Mathematics and Science.

Geographical disparities play a significant role in palliative and end-of-life care access. This study assessed availability of palliative and end of life (hospice) care in South Dakota. Grounded in a conceptual model of advance care planning, this assessment explored whether South Dakota health care facilities had contact persons for palliative care, hospice services, and advance directives; health care providers with specialized training in palliative and hospice care; and a process for advance directives and advance care planning. Trained research assistants conducted a brief telephone survey. Of 668 health care eligible facilities, 455 completed the survey for a response rate of 68 percent (455 out of 668). Over one-half of facilities had no specific contact person for palliative care, hospice services and advance directives. Nursing homes reported the highest percentage of contacts for palliative care, hospice services and advance directives. Despite a lack of a specific contact person, nearly 75 percent of facilities reported having a process in place for addressing advance directives with patients; slightly over one-half (53 percent) reported having a process in place for advance care planning. Of participating facilities, 80 percent had no staff members with palliative care training, and 73 percent identified lack of staff members with end-of-life care training. Palliative care training was most commonly reported among hospice/home health facilities (45 percent). The results of this study demonstrate a clear need for a health care and allied health care workforce with specialized training in palliative and end-of-life care.

A new interpretation of the special theory of relativity

International Nuclear Information System (INIS)

Buonomano, V.

1975-01-01

Assuming the 'Big Bang' theory as well as the usual axioms in the Special Theory of Relativity, the time dilations and length contractions are treated as real physical effects. This becomes possible by relating everything to the hypothetical frame, Ssub(a), at rest relative to the 'Big Bang' event. This frame in many senses plays the role of the classical aether frame. A clock's real rhythm, as opposed to its rhythm observed by restricted methods, is then a function of its velocity relative to Ssub(a) (assuming a uniform gravitational field). It is further assumed that gravitational radiation is composed of 'electromagnetic-like' waves. Therefore when a clock changes its velocity in a uniform gravitational field it must receive a a different total energy due to the average frequency shift (Doppler effect), the time dilations are then caused by the change in energy due to this frequency shift. That is, no two clocks can be in the 'same' gravitational field unless they have no relative velocity, and therefore the Special Theory of Relativity is a special case of the General Theory from this viewpoint. Two feasible experimental tests, using the Moessbauer effect, are described that would decide on these viewpoints. The principle of equivalence and the 'twin paradox' are also discussed. (author)

The impact of new translation technologies on specialized texts

Directory of Open Access Journals (Sweden)

Matthieu LeBlanc

2016-03-01

Full Text Available The introduction of translation technologies, especially translation memory software, has had a significant impact on both the translator’s professional practice and the target text itself. Apart from the fact that he or she must translate in a non-linear fashion due to the design of translation memory systems, the translator is now called upon to increase output and, in many cases, recycle what has already been translated by others. As a result, the translator, used to having full control over his or her text, is in some regards losing control over the translation process, which brings him or her to reflect on the quality of the final product and, in turn, on the transformations the field of specialized translation is undergoing. In this paper, I will present the results of an important ethnographic study conducted in three Canadian translation environments. I will focus mostly on the effects translation technologies and newly implemented practices have had on the quality of specialized texts destined for the Canadian market, where most of the specialized texts produced in French are in fact translations. Special attention will be given to the comments made by specialized translators during semi-directed interviews.

Jurisdiction of courts with a focus on the Special Chamber of the Supreme Court of Kosovo

Directory of Open Access Journals (Sweden)

Mr.Sc. Sabri Halili

2013-06-01

Full Text Available The legal solution offered by the Law establishing the Special Chamber of the Supreme Court of Kosovo is rather challenging for practical implementation. Due to this fact, the decisions of the Special Chamber contain various dilemmas of judges on the jurisdiction of the Chamber on the matters related to natural persons sued by the PAK, which are related to various liabilities of these persons to socially-owned enterprises, namely to the PAK. Since the PAK administers and represents socially owned property in general, it is naturally bound to seek for legal resolutions for all legal contests before a competent court. Naturally, the PAK would seek for such a solution before the Special Chamber of the Supreme Court of Kosovo on PAK-related matters, which is already bound by the title itself, “on PAK-related matters”. Comparisons of remedies by various laws related to subject competence are based on legal literature used in higher education in Kosovo. Analysis of subject competences of regular and special courts is two-fold: the Commercial Court and the Military Court, while the competence of the Special Chamber is only analysed in relation with the Law on Courts, and the Law on the Special Chamber of the Supreme Court, comparing it with the Law on Contested Procedure and the Law on the PAK. The Special Chamber has before and still continues to avoid jurisdiction of this Court, which is sanctioned by Articles 4 and 5 of the Law on the Special Chamber, due to the fact that in cases in which the PAK has sued a natural or legal person, due to debts, occupation of socially owned property, or any other disputed matter, which is directly related to socially owned properties, the Special Chamber proclaims itself incompetent, and transfers the case to regular courts, although the Special Chamber adjudicates “on PAK-related matters”, but in this case only when the PAK is respondent, not when it is claimant.

Hospital dental practice in special patients

Silvestre-Rangil, Javier; Espín-Gálvez, Fernando

2014-01-01

Dental patients with special needs are people with different systemic diseases, multiple disorders or severe physical and/or mental disabilities. A Medline search was made, yielding a total of 29 articles that served as the basis for this study, which offers a brief description of the dental intervention protocols in medically compromised patients. Dental treatment in patients with special needs, whether presenting medical problems or disabilities, is sometimes complex. For this reason the hospital should be regarded as the ideal setting for the care of these individuals. Before starting any dental intervention, a correct patient evaluation is needed, based on a correct anamnesis, medical records and interconsultation reports, and with due assessment of the medical risks involved. The hospital setting offers the advantage of access to electronic medical records and to data referred to any complementary tests that may have been made, and we moreover have the possibility of performing treatments under general anesthesia. In this context, ambulatory major surgery is the best approach when considering general anesthesia in patients of this kind. Key words:Hospital dentistry, special patients, medically compromised patients. PMID:24121921

Energy security in South America and Southern Africa: synthesis report

Kiratu, Sheila

2011-01-01

In developing countries, the ability to provide adequate and reliable energy supplies is a key to sustainable economic development. The aim of this report is to study the energy supply security in both Southern Africa and South America and how these regions can participate in the international effort to combat climate change. This report showed that South Africa's energy sector mostly relies on carbon intensive coal while Brazil is mainly supplied by hydroelectricity. It was found that in both countries energy needs will increase significantly due to rising demand both internally and at a regional scale. However it was also shown that both Southern Africa and South America have important hydro, solar and wind renewable resources which could enhance their electricity security while minimizing their environmental impacts. This study demonstrated that Southern Africa and South America can enhance their electricity security through the use of renewable energies but that technology and financing is needed to develop the sector.

Modelling the South African fruit export infrastructure: A case study

Full Text Available A description is provided of work performed as part of the fruit logistics infrastructure project commissioned by the South African Deciduous Fruit Producers’ Trust and coordinated by the South African Council for Scientific and Industrial Research, as described in [Van Dyk FE & Maspero E, 2004, An analysis of the South African fruit logistics infrastructure, ORiON, 20(1, pp. 55–72]. After a brief introduction to the problem, two models (a single-commodity graph theoretic model and a multi-commodity mathematical programming model are derived for determining the maximal weekly flow or throughput of fresh fruit through the South African national export infrastructure. These models are solved for two extreme seasonal export scenarios and the solutions show that no export infrastructure expansion is required in the near future - observed bottlenecks are not fundamental to the infrastructure and its capacities, but are rather due to sub-optimal management and utilisation of the existing infrastructure.

The South/Southeast Asia Research Initiative (SARI) Update and Meeting Objectives

Land Use/Cover Change (LU/CC) is one of the most important types of environmental change in South and Southeast Asian countries. Several studies suggest that LU/CC in these countries is in large part driven by population growth and economic development. In the region, changes that are most common include urban expansion, agricultural land loss, land abandonment, deforestation, logging, reforestation, etc. To address the research needs and priorities in the region, a regional initiative entitled South Southeast Asia Regional Initiative (SARI) has been developed involving US and regional scientists. The initiative is funded by NASA Land Cover, Land Use Change program. The goal of SARI is to integrate state-of-the-art remote sensing, natural sciences, engineering and social sciences to enrich LU/CC science in South Southeast Asian countries. In the presentation, LU/CC change research in SARI countries will be highlighted including the drivers of change. For example, in South Asia, forest cover has been increasing in countries like India, Nepal and Bhutan due to sustainable afforestation measures; whereas, large-scale deforestation in Southeast Asian countries is still continuing, due to oil palm plantation expansion driven by the international market demand in Malaysia and Indonesia. With respect to urbanization, South and Southeast Asian countries contain 23 megacities, each with more than 10 million people. Rapid urbanization is driving agricultural land loss and agricultural intensification has been increasing due to less availability of land for growing food crops such as in India, Vietnam, and Thailand. The drivers of LUCC vary widely in the region and include such factors as land tenure, local economic development, government policies, inappropriate land management, land speculation, improved road networks, etc. In addition, variability in the weather, climate, and socioeconomic factors also drive LU/CC resulting in disruptions of biogeochemical cycles

Africa's middle class women bring entrepreneurial opportunities in breast care medical tourism to South Africa.

Ahwireng-Obeng, Frederick; van Loggerenberg, Charl

2011-01-01

Africa's distribution of specialized private health services is severely disproportionate. Mismatch between South Africa's excess supply and a huge demand potential in an under-serviced continent represents an entrepreneurial opportunity to attract patients to South Africa for treatment and recuperative holidays. However, effective demand for intra-African medical tourism could be constrained by sub-Saharan poverty. Results from interviewing 320 patients and five staff at the Johannesburg Breast care Centre of Excellence, however, reject this proposition, Africa's middle class women being the target market estimated to grow annually by one million while breast cancer incidence increases with middle-class lifestyles. Uncovering this potential involves an extensive marketing strategy. Copyright © 2010 John Wiley & Sons, Ltd.

Atmospheric pollution over South Asia attracts special attention due to its effects on regional climate, water cycle and human health. These effects are potentially growing owing to rising trends of anthropogenic aerosol emissions. In this study, the spatio-temporal aerosol distributions over South Asia from seven global aerosol models are evaluated against aerosol retrievals from NASA satellite sensors and ground-based measurements for the period of 2000-2007. Overall, substantial underestimations of aerosol loading over South Asia are found systematically in most model simulations. Averaged over the entire South Asia, the annual mean aerosol optical depth (AOD) is underestimated by a range 15 to 44% across models compared to MISR (Multi-angle Imaging SpectroRadiometer), which is the lowest bound among various satellite AOD retrievals (from MISR, SeaWiFS (Sea-Viewing Wide Field-of-View Sensor), MODIS (Moderate Resolution Imaging Spectroradiometer) Aqua and Terra). In particular during the post-monsoon and wintertime periods (i.e., October-January), when agricultural waste burning and anthropogenic emissions dominate, models fail to capture AOD and aerosol absorption optical depth (AAOD) over the Indo-Gangetic Plain (IGP) compared to ground-based Aerosol Robotic Network (AERONET) sunphotometer measurements. The underestimations of aerosol loading in models generally occur in the lower troposphere (below 2 km) based on the comparisons of aerosol extinction profiles calculated by the models with those from Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) data. Furthermore, surface concentrations of all aerosol components (sulfate, nitrate, organic aerosol (OA) and black carbon (BC)) from the models are found much lower than in situ measurements in winter. Several possible causes for these common problems of underestimating aerosols in models during the post-monsoon and wintertime periods are identified: the aerosol hygroscopic growth and formation of

The more than 1.5 billion people who live in South Asia are correctly viewed not as a single large population but as many small endogamous groups. We assembled genome-wide data from over 2,800 individuals from over 260 distinct South Asian groups. We identified 81 unique groups, 14 of which had estimated census sizes of more than 1 million, that descend from founder events more extreme than those in Ashkenazi Jews and Finns, both of which have high rates of recessive disease due to founder events. We identified multiple examples of recessive diseases in South Asia that are the result of such founder events. This study highlights an underappreciated opportunity for decreasing disease burden among South Asians through discovery of and testing for recessive disease-associated genes.

The dire need for primary care specialization in India: Concerns and challenges

Full Text Available Primary health care is an evidence-based priority, but it is still inadequately supported in many countries. Ironically, on one hand, India is a popular destination for medical tourism due to the affordability of high quality of health care and, on the other hand, ill health and health care are the main reasons for becoming poor through medical poverty traps. Surprisingly, this is despite the fact that India was committed to 'Health for All by 2000' in the past, and is committed to 'Universal Health Coverage' by 2022! Clearly, these commitments are destined to fail unless something is done to improve the present state of affairs. This study argues for the need to develop primary care as a specialization in India as a remedial measure to reform its health care in order to truly commit to the commitments. Three critical issues for this specialization are discussed in this review: (1 The dynamic and distinct nature of primary care as opposed to other medical specializations, (2 the intersection of primary care and public health which can be facilitated by such a specialization, and (3 research in primary care including the development of screening and referral tools for early diagnosis of cancers, researches for evidence-based interventions via health programs, and primary care epidemiology. Despite the potential challenges and difficulties, India is a country in dire need for primary care specialization.

2015-12-01

Full Text Available This article is aimed at augmenting current awareness of virtual currencies ("VCs" in the South African legal community. To this end, it introduces the reader to VCs in general and decentralised convertible VCs ("DCVCs" in particular. Due to their design and interaction with the real economy and currency, DCVCs are on the radar of many financial regulators worldwide. As Bitcoin is considered the leading type of DCVC in terms of value and volume, its early beginnings in South Africa are probed. Although regulation should follow innovation, awareness of the VC ecosystem will not only warrant appropriate regulatory intervention when the time comes, but will also enable the growth and development opportunities associated with VCs. South Africa has not promulgated any legislation pertaining to VCs. The potential applicability of all current legislation and regulations relevant to VCs calls for in-depth research. This article aspires to serve as an appetiser to do so.

Regionalization of Drought across South Korea Using Multivariate Methods

2017-12-01

Full Text Available Topographic and hydro-climatic features of South Korea are highly heterogeneous and able to influence the drought phenomena in the region. The complex topographical and hydro-climatic features of South Korea need a statistically accurate method to find homogeneous regions. Regionalization of drought in a bivariate framework has scarcely been applied in South Korea before. Hierarchical Classification on Principal Components (HCPC algorithm together with Principal Component Analysis (PCA method and cluster validation indices were investigated and used for the regionalization of drought across the South Korean region. Statistical homogeneity and discordancy of the region was tested on univariate and bivariate frameworks. HCPC indicate that South Korea should be divided into four regions which are closer to being homogeneous. Univariate and bivariate homogeneity and discordancy tests showed the significant difference in their results due to the inability of univariate homogeneity and discordancy measures to consider the joint behavior of duration and severity. Regionalization of drought for SPI time scale of 1, 3, 6, 12, and 24 months showed significant variation in discordancy and homogeneity of the region with the change in SPI time scale. The results of this study can be used as basic data required to establish a drought mitigation plan on regional scales.

National viewpoints: Views on strengthened safeguards from Australia, Cuba and South Africa

International Nuclear Information System (INIS)

Biggs, I.; Saburido, E.F.; Mxakato-Diseko, N.J.

1999-01-01

This paper presents views of Australia, Cuba and South Africa concerned with strengthened safeguards regime. Australia has been involved with the IAEA safeguards system since the first plenary meeting of the Conference on the IAEA Statute in 1956, joined the NPT in 1973 and began concluding bilateral safeguards agreements in 1977. Australia has the greatest respect for the IAEA coordinated efforts started in 1998 to strengthen and integrate the safeguards system. Cuba has always attached special importance to nuclear safeguards activities, recognizing their high priority as well as the important role they have in respect to international disarmament and security. South Africa supports the efforts in strengthening the safeguards activities and remains hopeful that the international community will address the challenges posed by the Trilateral Initiative between Russian federation, USA and IAEA in a mature and cooperative way

In this work it is presented the description of the model adopted in the structural calculations for a modification in the CNAAA Unit I South Auxiliary Building. This modification intended to increase the facilities destinated to keeping and changing of special clothing for access to the controlled area. The design basically constitutes of a slab at the Elevation 5,15m, for which a tridimensional frame model was adopted, in reinforced adopted concrete, fixed in the South Auxiliary Building foundation slab and structurally independent on the building, at the slab level. It was demonstrated in this study that the introduction, in the existing structure, of the masses of this enlarged area does not considerably change the dynamic behaviour of the building, which allowed proceeding the analysis of the new structure independently of the existing one.

Electro-thermal injuries due to high-current accidents with special regard to the skeletal muscles

Energy Technology Data Exchange (ETDEWEB)

Rausch, M.

1982-02-25

Seven patients suffering from high-current accidents with different degrees of severity are reported on. Damages to the striped musculature are preferentially considered. When the function of the cellular membrane is affected by an electric current, the Na/sup +//K/sup +/ mechanism collapses due to an increase of membrane permeability for calcium. Depolarisation, development of contractures, changes of the fibrillar structures and decay of the stripes or swelling of the Q (A) substance were found to indicate damage. A particular effect of electrothermal muscle damages is the affection of other organs, e.g. of the kidneys, provoked by an increased chromoprotein production and a higher output of myoglobin and hemoglobin. Since in case of an accident due to electric current affecting the musculature, more acid substances enter the vascular system, an acute renal damage provoked by an alkalinisation of the urine, shall be treated by drugs. In most cases, an anuria, occurring several days after deep burn of musculature, is a so-called constipational anuria, if it is not an anuria induced by a decrease of blood pressure or by shock. The therapy of wounds due to electrical burning depends on the size of the affected skin area and down to which depth the tissue is burnt. Particular attention must be paid to the affection of bones being situated in the depth of wounds due to burning. In the last part of the study possible reconstructive and ensuing rehabilitation measures are indicated.

Special geometry

International Nuclear Information System (INIS)

Strominger, A.

1990-01-01

A special manifold is an allowed target manifold for the vector multiplets of D=4, N=2 supergravity. These manifolds are of interest for string theory because the moduli spaces of Calabi-Yau threefolds and c=9, (2,2) conformal field theories are special. Previous work has given a local, coordinate-dependent characterization of special geometry. A global description of special geometries is given herein, and their properties are studied. A special manifold M of complex dimension n is characterized by the existence of a holomorphic Sp(2n+2,R)xGL(1,C) vector bundle over M with a nowhere-vanishing holomorphic section Ω. The Kaehler potential on M is the logarithm of the Sp(2n+2,R) invariant norm of Ω. (orig.)

The Yoruba's cultural perspective of death with special reference to twins.

Olaleye-Oruene, Taiwo O

2002-06-01

To the Yoruba people of South-West Nigeria, on the West Coast of Africa, death, or transition from one level of existence to another, is well accepted as part of life. Rites of passage are seen as an opportunity for saying farewell to the deceased and seeking their continuous protection of the living members of the families. After the death of a twin, a twin statuette, symbolically representing the departed twin, also acts as a companion and solace to the living twin. This paper examines these subjects including the special rites performed for twins, the relationship of the family to the deceased and the question of reincarnation

Marketing of irradiated commodities in South Africa

Science.gov (United States)

Du Plessis, TA; Stevens, RCB

Although the industrial exploitation of radiation processing in the medical and allied fields has been successfully marketed and applied for the past two decades in South Africa, the introduction of food radurisation on an industrial level adds a completely new dimension to the marketing of this processing technique. Extensive research into the use of radiation for the treatment of various foodstuffs has been carried out by the Nuclear Development Corporation of South Africa for more than a decade, resulting in South Africa being one of the first countries where a commercial irradiator dedicated to this branch of radiation processing, was established. The marketing of this process is especially difficult due to the emotive aspects associated with radiation and man's sensitive reaction to anything pertaining to his food. This situation was made even more difficult by the general public's apprehension towards nuclear activities throughout the world. In an attempt to transform the unfavourable public image associated with this process, an important first step was to form a National Steering Committee for the Marketing of Radurised Food, the members of which were drawn from various agricultural controlling bodies, the Department of Health, and other controlling bodies held in high esteem by the public, such as the Consumer Council and representatives from commerce and industry. This approach proved to be very successful and greatly assisted in creating a climate whereby the public in South Africa today generally has a favourable attitude towards the radurisation of foodstuffs. The development of this marketing strategy for food radurisation in South Africa is discussed in detail.

South-South medical tourism and the quest for health in Southern Africa.

Science.gov (United States)

Crush, Jonathan; Chikanda, Abel

2015-01-01

Intra-regional South-South medical tourism is a vastly understudied subject despite its significance in many parts of the Global South. This paper takes issue with the conventional notion of South Africa purely as a high-end "surgeon and safari" destination for medical tourists from the Global North. It argues that South-South movement to South Africa for medical treatment is far more significant, numerically and financially, than North-South movement. The general lack of access to medical diagnosis and treatment in SADC countries has led to a growing temporary movement of people across borders to seek help at South African institutions in border towns and in the major cities. These movements are both formal (institutional) and informal (individual) in nature. In some cases, patients go to South Africa for procedures that are not offered in their own countries. In others, patients are referred by doctors and hospitals to South African facilities. But the majority of the movement is motivated by lack of access to basic healthcare at home. The high demand and large informal flow of patients from countries neighbouring South Africa has prompted the South African government to try and formalise arrangements for medical travel to its public hospitals and clinics through inter-country agreements in order to recover the cost of treating non-residents. The danger, for 'disenfranchised' medical tourists who fall outside these agreements, is that medical xenophobia in South Africa may lead to increasing exclusion and denial of treatment. Medical tourism in this region and South-South medical tourism in general are areas that require much additional research. Copyright © 2014. Published by Elsevier Ltd.

Developing electricity production with natural gas in the southern mediterranean countries. An example of north-south cooperation in the electricity and natural gas sectors

International Nuclear Information System (INIS)

Grenon, M.; Nogaret, E.

1996-01-01

The countries of the Southern Mediterranean region are facing an important increase of electricity demand due to their socio-economic development. In order to increase the production capacity at a minimum cost while preserving the environment, most countries of the region are planning gas fired power stations due to the important natural gas resources in the area. Overall investments in new power plants could reach the total of 100 billion dollars, up to the horizon 2010. The development of both the power plants and the infrastructure to produce and transport the natural gas needed is more and more performed through cooperation between companies of the two shores of the Mediterranean and represent an example of North- South cooperation in the energy field. This cooperation is taking place through technical assistance programs and also joint financing and management of the infrastructure required. A special importance is given to the development of highly efficient combined cycle power plants in the Southern Mediterranean countries and to the increase of the activities related to the exploration and production of natural gas.

Reis, R E; Albert, J S; Di Dario, F; Mincarone, M M; Petry, P; Rocha, L A

2016-07-01

The freshwater and marine fish faunas of South America are the most diverse on Earth, with current species richness estimates standing above 9100 species. In addition, over the last decade at least 100 species were described every year. There are currently about 5160 freshwater fish species, and the estimate for the freshwater fish fauna alone points to a final diversity between 8000 and 9000 species. South America also has c. 4000 species of marine fishes. The mega-diverse fish faunas of South America evolved over a period of >100 million years, with most lineages tracing origins to Gondwana and the adjacent Tethys Sea. This high diversity was in part maintained by escaping the mass extinctions and biotic turnovers associated with Cenozoic climate cooling, the formation of boreal and temperate zones at high latitudes and aridification in many places at equatorial latitudes. The fresh waters of the continent are divided into 13 basin complexes, large basins consolidated as a single unit plus historically connected adjacent coastal drainages, and smaller coastal basins grouped together on the basis of biogeographic criteria. Species diversity, endemism, noteworthy groups and state of knowledge of each basin complex are described. Marine habitats around South America, both coastal and oceanic, are also described in terms of fish diversity, endemism and state of knowledge. Because of extensive land use changes, hydroelectric damming, water divergence for irrigation, urbanization, sedimentation and overfishing 4-10% of all fish species in South America face some degree of extinction risk, mainly due to habitat loss and degradation. These figures suggest that the conservation status of South American freshwater fish faunas is better than in most other regions of the world, but the marine fishes are as threatened as elsewhere. Conserving the remarkable aquatic habitats and fishes of South America is a growing challenge in face of the rapid anthropogenic changes of the 21

Background With 17 babies born with hearing loss every day in South Africa, there is a pressing need for systematic Early Hearing Detection and Intervention (EHDI) services. Progress is being made in offering newborn hearing screening and studies have been conducted to document these processes within South Africa. However, due to the lack of a national and holistic overview of EHDI services to date, an accurate picture of the current status of EHDI within the South African context is required. Objective To document and profile what has been published within the field of EHDI in South Africa over the last two decades (Jan 1995–Sept 2014) in order to gain a comprehensive overview of the current status and practice of screening and diagnosis in the field of paediatric hearing loss. Method A narrative review of peer-reviewed articles related to EHDI in South Africa was conducted by searching the EBSCOHOST, SCOPUS and JSTOR databases for the period January 1995 to September 2014. Results Results indicate that over the last two decades research and publications in the field of EHDI have increased considerably. These publications have revealed extensive knowledge related to paediatric hearing screening and intervention services in South Africa; however, this knowledge seems to be limited primarily to the provinces of Gauteng and the Western Cape. Furthermore, studies pertaining to diagnosis have revealed that, although much has been written on the scientific aspects on tools for diagnosis of hearing loss, there is a lack of comprehensive information on diagnostic protocols and procedures. Conclusion Despite the clear progress being made in South Africa in the field of early hearing detection and intervention, there is a need for comprehensive studies on protocols and procedures in diagnosing paediatric hearing loss. Finally, the narrative review revealed a clear need to ensure that development and growth in the field of EHDI is a national priority and extends beyond the

Full Text Available Medical tourism aims at providing cost-effective customized health care in collaboration with the tourism industry in distant locations wherein the hospitality component is handled efficiently so that fixing appointments, making arrangements for accommodation and other logistics become hassle-free for the patient. This allows more concentration on the procedure at hand and the interaction between the medical fraternity and the patient becomes smoother. More and more hospitals in India are gearing up to provide such services to neighbouring countries and even to the developed nations across the world. The purpose of this study was to study the knowledge, attitude and experiences of the population of a suitable cross-section regarding the emerging scenario of medical tourism with special interest vis-à-vis Non Resident Indians (NRIs specifically to the state of Karnataka and Mangalore in particular. It was found that compared to the locals (kannadigas or non-kannadigas, the Non-resident Indians were more dissatisfied with the health care facilities available in their proximity. Though a majority of them do have medical insurance, it still looks as if the care is more cost-effective when sourced to India. NRIs are more aware of the potential of medical tourism through their communication with the medical fraternity as well as the general public and 11.1% of NRIs have really utilized the services of medical tourism. An e-mail survey which was also conducted among a number of foreigners yielded the interesting fact that they indeed had a greater awareness regarding medical tourism with an emphasis on health tourism. The reason why these foreigners opted for medical tourism was due to the substandard medical care available in their locality, rather than due to the cost of medical care as such.

2009-03-01

Education of health professionals using principles of community-based education is the recommended national policy in South Africa. A paradigm shift to community-based education is reported in a number of nursing education institutions in South Africa. Reviewed literature however revealed that in some educational institutions planning, implementation and evaluation of Community-based Educational (CBE) programmes tended to be haphazard, uncoordinated and ineffective, resulting in poor student motivation. Therefore the purpose of this study was to analyse the implementation of community-based education in basic nursing education programmes in South Africa. Strauss and Corbin's (1990) grounded theory approach guided the research process. Data were collected by means of observation, interviews and document analysis. The findings revealed that collaborative decision-making involving all stakeholders was crucial especially during the curriculum planning phase. Furthermore, special criteria should be used when selecting community learning sites to ensure that the selected sites are able to facilitate the development of required graduate competencies. Collaborative effort, true partnership between academic institutions and communities, as well as government support and involvement emerged as necessary conditions for the successful implementation of community-based education programmes.

2012-01-01

BACKGROUND AND AIMS The extreme complexity of asclepiad flowers (Asclepiadoideae-Apocynaceae) has generated particular interest in the pollination biology of this group of plants especially in the mechanisms involved in the pollination processes. This study compares two South American species, Morrenia odorata and Morrenia brachystephana, with respect to morphology and anatomy of flower structures, dynamic aspects of the pollination mechanism, diversity of visitors and effectiveness of pollinators. Floral structure was studied with fresh and fixed flowers following classical techniques. The pollination mechanism was studied by visiting fresh flowers in the laboratory with artificial pollinator body parts created with an eyelash. Morphometric and nectar measurements were also taken. Pollen transfer efficiency in the flowers was calculated by recording the frequency of removed and inserted pollinia. Visitor activity was recorded in the field, and floral visitors were captured for subsequent analysis of pollen loads. Finally, pollinator effectiveness was calculated with an index. The detailed structure of the flowers revealed a complex system of guide rails and chambers precisely arranged in order to achieve effective pollinaria transport. Morrenia odorata is functionally specialized for wasp pollination, and M. brachystephana for wasp and bee pollination. Pollinators transport chains of pollinaria adhered to their mouthparts. Morrenia odorata and M. brachystephana present differences in the morphology and size of their corona, gynostegium and pollinaria, which explain the differences in details of the functioning of the general pollination mechanism. Pollination is performed by different groups of highly effective pollinators. Morrenia species are specialized for pollination mainly by several species of wasps, a specialized pollination which has been poorly studied. In particular, pompilid wasps are reported as important pollinators in other regions outside South

Since the revolutionary experimental discovery of graphene in the year 2004, research on this new two-dimensional carbon allotrope has progressed at a spectacular pace. The impact of graphene on different areas of research— including physics, chemistry, and applied sciences— is only now starting to be fully appreciated. There are different factors that make graphene a truly impressive system. Regarding nano-electronics and related fields, for instance, it is the exceptional electronic and mechanical properties that yield very high room-temperature mobility values, due to the particular band structure, the material `cleanliness' (very low-concentration of impurities), as well as its stiffness. Also interesting is the possibility to have a high electrical conductivity and optical transparency, a combination which cannot be easily found in other material systems. For other fields, other properties could be mentioned, many of which are currently being explored. In the first years following this discovery, research on graphene has mainly focused on the fundamental physics aspects, triggered by the fact that electrons in graphene behave as Dirac fermions due to their interaction with the ions of the honeycomb lattice. This direction has led to the discovery of new phenomena such as Klein tunneling in a solid state system and the so-called half-integer quantum Hall effect due to a special type of Berry phase that appears in graphene. It has also led to the appreciation of thicker layers of graphene, which also have outstanding new properties of great interest in their own right (e.g., bilayer graphene, which supports chiral quasiparticles that, contrary to Dirac electrons, are not massless). Now the time is coming to deepen our knowledge and improve our control of the material properties, which is a key aspect to take one step further towards applications. The articles in the Semiconductor Science and Technology Graphene special issue deal with a diversity of topics

Canine distemper infections, with special reference to South Africa, with a review of the literature : review article

Directory of Open Access Journals (Sweden)

A.L. Leisewitz

2001-07-01

Full Text Available Canine distemper virus is a member of the genus Morbillivirus of the family Paramyxoviridaethat causes severe disease in dogs and a range of wild mammals. The clinical signs relate essentially to the respiratory, gastrointestinal and central nervous systems. In South Africa, infection with Ehrlichia canis and canine parvovirus may present similarly. Many dogs will initially present with a wide range of central nervous system signs without any history of systemic disease. A recent South African study evaluating ante mortem diagnosis highlighted the importance of recognising clinical signs, cerebrospinal fluid IgG titres, serum IgM titres and immunocytochemistry of epithelial tissue. A 2-year retrospective evaluation of cerebrospinal fluid samples collected from dogs presented to the Onderstepoort Veterinary Academic Hospital indicates that distemper infection is common, and this disease should routinely be suspected in cases of diverse neurological disease in dogs. The South African dog population is specifically at high risk for the disease because of the large pool of unvaccinated, reproductively-active dogs that expose the wildlife resources of the country to risk of fatal disease. Outbreaks of disease in dogs continue to occur in developed and developing communities in both vaccinated and unvaccinated dogs worldwide, and have also been described in a wide range of free-ranging wildlife, including seals, dolphins and lions, and in endangered zoo animals. Modified live virus vaccines have contributed markedly to disease control in the dog population but have caused mortality in some wild carnivores. New recombinant vaccines are being developed that will be safe in wild animals. The pathogenesis of CNS demyelination has been compared to various important demyelinating diseases in humans and, amongst other things, relates to down-regulation of the oligodendrocyte gene coding for myelin synthesis and non-immunocyte CNS cell expression of type II

In many developing countries in the South Asian region, screening for chronic diseases in the community has shown a widely varying prevalence. However, certain geographical regions have shown a high prevalence of chronic kidney disease (CKD) of unknown etiology. This predominantly affects the young and middle-aged population with a lower socioeconomic status. Here, we describe the hotspots of CKD of undiagnosed etiology in South Asian countries including the North, Central and Eastern provinces of Sri Lanka and the coastal region of the state of Andhra Pradesh in India. Screening of these populations has revealed cases of CKD in various stages. Race has also been shown to be a factor, with a much lower prevalence of CKD in whites compared to Asians, which could be related to the known influence of ethnicity on CKD development as well as environmental factors. The difference between developed and developing nations is most stark in the realm of healthcare, which translates into CKD hotspots in many regions of South Asian countries. Additionally, the burden of CKD stage G5 remains unknown due to the lack of registry reports, poor access to healthcare and lack of an organized chronic disease management program. The population receiving various forms of renal replacement therapy has dramatically increased in the last decade due to better access to point of care, despite the disproportionate increase in nephrology manpower. In this article we will discuss the nephrology care provided in various countries in South Asia, including India, Bangladesh, Pakistan, Nepal, Bhutan, Sri Lanka and Afghanistan.

Through the Fear: A Study of Xenophobia in South Africa’s Refugee System

Directory of Open Access Journals (Sweden)

Janet McKnight

2008-11-01

Full Text Available In light of the May 2008 xenophobic attacks in Gauteng and Western Cape Provinces, this paper explains the process of refugee law in South Africa as stated in theory and as implemented in practice. Research was compiled through visits to refugee camps, townships, South African Parliament, regional prisons, judicial inspectorates, universities, and community events in and near Cape Town during June 2008. The South African Refugees Act guarantees protection to refugees and asylum seekers in conformity with international treaties and the South African Constitution. However, these rights are seldom realized due to a delay processing of asylum applications by the Department of Home Affairs, corruption in immigration enforcement, and a lack of education in civil society as to the difference between refugees and voluntary migrants. Refugees are left vulnerable to the violence of those South African citizens that believe all immigrants are illegally present to take advantage of employment and social opportunities. In an attempt to eliminate the fearfulness towards foreigners and bring the plight of refugees further to the forefront of international dialogue, general recommendations are made to the South African Government, its departments, and the citizens of South Africa.

This paper presents application of an indicator protocol to assessment of current levels of governance capacity of the Specialized Component of Pharmaceutical Services (CEAF) in a state of the South of Brazil. We chose the theoretical referential of 'governance capacity' proposed by Carlos Matus, which reflects in the concepts of management capacity and pharmaceutical service management, due to the perception of a need to overcome the fragmentation and technicist reductionism that we believe has been imposed on the area of pharmaceutical services. Data was collected using the protocol in 74 municipal or state units. The results of the analysis indicate that the currently existing governance capacity needs improvement in all three dimensions that were evaluated, principally in relation to the aspects that seek sustainability of the governance. The model and the protocol used indicate a way forward for governance of pharmaceutical service by proposing a change from the technicist-logistical focus to an emphasis on strategic and political actions, or ones which foster greater participation and autonomy. With these results in hand, it will be possible to develop strategies for improvement of access to medicines in the SUS, in the sense that the CEAF becomes able to guarantee integrality of medicines treatments.

The water economy of South American desert rodents: from integrative to molecular physiological ecology.

Science.gov (United States)

Bozinovic, Francisco; Gallardo, Pedro

2006-01-01

Rodents from arid and semi-arid habitats live under conditions where the spatial and temporal availability of free water is limited, or scarce, thus forcing these rodents to deal with the problem of water conservation. The response of rodents to unproductive desert environments and water deficits has been intensively investigated in many deserts of the world. However, current understanding of the cellular, systemic and organismal physiology of water economy relies heavily on short-term, laboratory-oriented experiments, which usually focus on responses at isolated levels of biological organization. In addition, studies in small South American mammals are scarce. Indeed xeric habitats have existed in South America for a long time and it is intriguing why present day South American desert rodents do not show the wide array of adaptive traits to desert life observed for rodents on other continents. Several authors have pointed out that South American desert rodents lack physiological and energetic specialization for energy and water conservation, hypothesizing that their success is based more on behavioral and ecological strategies. We review phenotypic flexibility and physiological diversity in water flux rate, urine osmolality, and expression of water channels in South American desert-dwelling rodents. As far as we know, this is the first review of integrative studies at cellular, systemic and organismal levels. Our main conclusion is that South American desert rodents possess structural as well as physiological systems for water conservation, which are as remarkable as those found in "classical" rodents inhabiting other desert areas of the world.

[Attitudes towards psychotherapy in South Korea and Germany : A cross-cultural comparative study].

Schulz, W; Shin, M A; Schmid-Ott, G

2018-01-01

Due to the relatively recent introduction of psychotherapy in South Korea and against the background of collectivist and Confucian values, it has been suggested that South Koreans harbor more negative attitudes towards psychotherapy compared to Germans and that the social acceptance of psychotherapy is lower. We compared the attitudes of 99 women from South Korea with 98 German women using the questionnaire on attitudes towards psychotherapeutic treatment (FEP). For the study of the South Korean women we translated the questionnaire into the Korean language. The results of the psychometric analysis suggest that the Korean version of the FEP is of acceptable quality. South Korean women reported a significantly more negative attitude towards psychotherapy compared to German women. Furthermore, South Korean women anticipated a more skeptical social attitude towards psychotherapy compared to Germans. The presented results suggest the relevance of cultural imprinting in psychotherapy. They are discussed with respect to culture-specific self-concepts, concepts of disease and healing expectations and the increase of individualistic values in the Korean society.

South American climate during the Last Glacial Maximum: Delayed onset of the South American monsoon

Science.gov (United States)

Cook, K. H.; Vizy, E. K.

2006-01-01

The climate of the Last Glacial Maximum (LGM) over South America is simulated using a regional climate model with 60-km resolution, providing a simulation that is superior to those available from global models that do not resolve the topography and regional-scale features of the South American climate realistically. LGM conditions on SST, insolation, vegetation, and reduced atmospheric CO2 on the South American climate are imposed together and individually. Remote influences are not included. Annual rainfall is 25-35% lower in the LGM than in the present day simulation throughout the Amazon basin. A primary cause is a 2-3 month delay in the onset of the rainy season, so that the dry season is about twice as long as in the present day. The delayed onset occurs because the low-level inflow from the tropical Atlantic onto the South American continent is drier than in the present day simulation due to reduced evaporation from cooler surface waters, and this slows the springtime buildup of moist static energy that is needed to initiate convection. Once the monsoon begins in the Southern Hemisphere, LGM rainfall rates are similar to those in the present day. In the Northern Hemisphere, however, rainfall is lower throughout the (shortened) rainy season. Regional-scale structure includes slight precipitation increases in the Nordeste region of Brazil and along the eastern foothills of the Andes, and a region in the center of the Amazon basin that does not experience annual drying. In the Andes Mountains, the signal is complicated, with regions of significant rainfall increases adjacent to regions with reduced precipitation.

Transmutations: Rejuvenation, Longevity, and Immortality Practices in South and Inner Asia

Directory of Open Access Journals (Sweden)

Dagmar Wujastyk

2017-12-01

Full Text Available Wild and diverse outcomes are associated with transmutational practices: the prolongation of life, the recovery of youth, the cure of diseases, invincibility, immortality, enlightenment, liberation from the cycle of rebirths, and unending bliss. This range of outcomes is linked to specific practices taught in separate traditions and lineages in medical, alchemical, yogic and tantric milieus across South and Inner Asia. These practices can be individual or collective, esoteric or secular, and occur in different places from hospital to village to monastery; they involve transmutations of substances as well as transmutations of the body. Every expression by a particular lineage has a distinguishing articulation. Yet there are also very clear commonalities and interconnections between the traditions’ aims, methods and expected results. In this special issue of HSSA, we examine transmutational practices and their underlying concepts in this wider context of South and Inner Asian culture. How do these practices and ideas connect and cross-fertilise? And conversely, how are they delineated and distinct?

South Asian participation in clinical trials: the views of lay people and health professionals.

Science.gov (United States)

Hussain-Gambles, Mah; Atkin, Karl; Leese, Brenda

2006-07-01

There is little UK-based empirical research on South Asian participation in clinical trials. The predominantly US literature rarely engages with mainstream debates about ethnicity, diversity and difference. This study was prompted by a lack of knowledge about how South Asian people perceive trial involvement and the risks and benefits involved. Face to face interviews were conducted with 25 health professionals (consultants, GPs, nursing staff, academics, non-medically trained trial co-ordinators, LREC and MREC members) and 60 South Asian lay people (20 Indians, 20 Pakistanis and 20 Bangladeshis) who had not taken part in a trial. The study took place in the Leeds and Bradford areas of England. It was found that lay South Asian attitudes towards clinical trial participation focused on similarities rather than differences with the general UK population, suggesting that the relevance of ethnicity should be kept in perspective. There was no evidence of antipathy amongst South Asians to the concept of clinical trials, and awareness was a correlate of social class, education and younger age. Lay factors that might affect South Asian participation in clinical trials included: age; language, social class; feeling of not belonging/mistrust; culture and religion. Approachable patients (of the same gender, social class and fluent in English) tended to be 'cherry picked' to clinical trials. This practice was justified because of a lack of time, resources and inadequate support. South Asian patients might be systematically excluded from trials due to the increased cost and time associated with their inclusion, particularly in relation to the language barrier. Under-representation might also be due to passive exclusion associated with cultural stereotypes. The paper concludes by applying the theoretical framework of institutional racism as a means of making sense of policy and practice. At the same time, caution is advocated against using ethnicity as the only form of

Rwandan family medicine residents expanding their training into South Africa: the use of South-South medical electives in enhancing learning experiences.

Flinkenflögel, Maaike; Ogunbanjo, Gboyega; Cubaka, Vincent Kalumire; De Maeseneer, Jan

2015-08-01

International medical electives are well-accepted in medical education, with the flow of students generally being North-South. In this article we explore the learning outcomes of Rwandan family medicine residents who completed their final year elective in South Africa. We compare the learning outcomes of this South-South elective to those of North-South electives from the literature. In-depth interviews were conducted with Rwandan postgraduate family medicine residents who completed a 4-week elective in South Africa during their final year of training. The interviews were thematically analysed in an inductive way. The residents reported important learning outcomes in four overarching domains namely: medical, organisational, educational, and personal. The learning outcomes of the residents in this South-South elective had substantial similarities to findings in literature on learning outcomes of students from the North undertaking electives in the Southern hemisphere. Electives are a useful learning tool, both for Northern students, and students from universities in the South. A reciprocity-framework is needed to increase mutual benefits for Southern universities when students from the North come for electives. We suggest further research on the possibility of supporting South-South electives by Northern colleagues.

International Nuclear Information System (INIS)

Fischer, D.

1990-01-01

This paper reports that South Africa's main reason for entering the international nuclear market is, and always has been, to sell its uranium abroad. From 1939-45 South Africa took part in the war against Nazi Germany, and the South African government of the time sought to help the Allied war effort in all ways that were practical. Later, during the Cold War, it tried to help build up the West's nuclear arsenal. In 1944, the British government secretly asked General Smuts---prime minister of South Africa since 1939 and a member of Churchill's War Cabinet---to survey South Africa's deposits of uranium. The survey, carried out with U.S. and British help, showed that the deposits were large, generally low-grade, but, in most cases, associated with gold and therefore could be profitably mined. In 1951, South Africa became a significant producer, with lucrative contracts for the sale of all its output to the U.S.-U.K.-Canada Joint Development Agency and one of the three main suppliers to the U.S. nuclear weapons program. In time, government controls eased and uranium production and marketing became a purely commercial operation

The Relevance of Criminal Courts in the Global South

Directory of Open Access Journals (Sweden)

Pablo Leandro Ciocchini

2017-12-01

Full Text Available The literature on comparative law has a long and robust tradition, but studies comparing courts and judicial systems are scarce. Comparative studies in the Global South, following Shapiro’s institutional approach, have aimed to measure the involvement of courts in politics by assessing the power of the judiciary in society, the level of judicial independence, and their role in the context of the judicialization of politics. The focus was on the high courts, including either Constitutional or Supreme Courts. Criminal courts have not received similar attention despite the influence of their everyday decisions on people’s lives and their perception of the judicial system. This article argues that developing a comparative approach for criminal courts in the Global South is needed to help understand the role they play in the development of the rule of law and democratic life. This comparative study helps understand the impact of judicial reform programmes in the Global South. These reforms, inspired by a neoliberal paradigm, have focused on improving the efficiency of the courts. The reforms have promoted managerial techniques detrimental to the standards of due process. Any assessment of the impact of the reforms on the courts in the Global South should start by recognising the widely differing settings under which they operate. This context is characterised by serious economic constraints, such as a lack of material and human resources, and a democratic deficit legacy from the past authoritarian regimes, including widespread police abuse and corruption. Given this context, the role of the courts in ensuring due process and the legality of police procedures is crucial. The impact of the judicial reforms promoting managerial rationality in recent decades must be analysed. To examine the role courts are playing in criminal matters, two cases were explored where courts have undergone extensive judicial reforms, Argentina and the Philippines.

Worsening of Heat Stress Due To Global Warming in South Korea Based on Multi-RCM Ensemble Projections

Science.gov (United States)

Im, Eun-Soon; Choi, Yeon-Woo; Ahn, Joong-Bae

2017-11-01

This study assesses the future changes in summer (June-July-August; JJA) heat stress over South Korea under global warming. To better resolve the region-specific changes in terms of geographical patterns and severity of heat stress in the Korean peninsula, four regional climate models (RCMs) are used for dynamical downscaling of Hadley Centre Global Environmental Model version 2—Atmosphere and Ocean global projections forced by two Representative Concentration Pathway (RCP4.5 and RCP8.5) scenarios. Dynamically downscaled simulations (horizontal resolution of 12.5 km and output interval of 3 h) facilitate in-depth analysis of diurnal variation and extremes over South Korea, as well as focusing on the particular location, Daegu, that is characterized by high vulnerability to rising temperature. Both maximum temperature and heat stress indices such as wet bulb globe temperature and apparent temperature, which include the effect of humidity, are examined in order to comprehensively interpret the behaviors of heat stress in response to anthropogenic climate change. Ensemble projections reveal robust patterns of temperature and resultant humidity increases that are roughly constrained by the approximate 7%/K increase in the moisture holding capacity. The changes in temperature and humidity are directly transmitted to the heat stress indices, showing a significant increase. The heat stress is exacerbated in a differentiated way, with more intensification in diurnal variation at nighttime and in regional variation at low-elevation basins. Both RCP4.5 and RCP8.5 scenarios project the statistical likelihood of a notable increase of extreme heat stress indices, much stronger and more extended heat waves, and the emergence of a long period of consecutive tropical nights.

Court Supervised Institutional Transformation in South Africa

Deon Erasmus

2015-12-01

problems to be properly addressed or where the executive fails to implement or even ignores court orders. Thus, the wrong which is complained of is not a wrong done to a particular person, but the constitutional wrong is the manner in which the institution executes its mandate vis-a-vis the vulnerable beneficiaries of the public service in question. The transformation thereof is designed to bring the institution within its constitutional duties and bounds. There is usually no dispute about the failures of the organisation and court orders are often taken by consent. The question which arises is how it can be ensured that a public institution such as a school, welfare department, hospital for the mentally disabled, home for the elderly or prison, which is designed to serve or accommodate the vulnerable may be brought into conformity with its constitutional mandate where there are continual and persistent failures to do so. Even where court orders are obtained, there are often significant problems with the implementation thereof. In the case of prisons, a possible solution, which has been employed in the United States of America and which may be adapted for use in the South African context, is that of a post-trial special master or court appointed supervisor, who supervises the transformation of the public institution until such time as the non-compliance has been appropriately resolved. In this article the role and functions of the American special master will be set out. The feasibility of importing such an office into the South African context will be evaluated

Brazing of special metallic materials and material combinations using a special material

International Nuclear Information System (INIS)

Lison, R.

1981-01-01

The special materials include metals of groups IVa, Va and VIa of the periodic tables and their alloys. Their particular properties have won them applications in many highly specialized industries. For these materials to be used, mastery of thermal joining methods appropriate to their characteristics is necessary. High-temperature brazing is one such method for joining special materials. This paper presents variants of this technique suitable for each individual special material. Compatibility tests between various brazing metals and various special materials have been carried out by simulating the temperature/time cycle involved in brazing procedures. Special materials are relatively expensive, and their special properties are not required at every point in a structure: elsewhere they can be replaced by a different special material or by other metals or alloys. This means that joints must be made between two special materials or between a special material and a conventional material. When certain conditions are fulfilled, such joins can be made by high-temperature brazing. This paper also shows the extent to which the geometry of the join determines the choice of process. Example of applications are also given. (orig.)

Saltburn following a summar gale in south-east England

Energy Technology Data Exchange (ETDEWEB)

Edlin, H L

1957-01-01

On July 29, 1956, a south-westerly gale of unusual violence swept Britain, and its effects on trees in the south-east are here discussed. Trees of most kinds near the coast showed extensive browning of leaves, followed by partial or complete foliation, on their seaward side; this is due to the deposition of salt. The varying susceptibility of different species is reviewed. Saltburn could be observed up to 50 miles inland and 750 ft. above sea level, but only on exposed ridges where the flow of air is apparently concentrated. Some trees near the coast put out fresh foliage, and even flowers. Although broadleaved trees were in full leaf, comparatively few were uprooted.

Beyond survival: Challenges facing South African automotive component exporters

Directory of Open Access Journals (Sweden)

M. J. Naude

2006-12-01

Full Text Available Purpose and Objective: The South African automotive component industry faces huge challenges in a very competitive global market. The primary focus of this research article is to determine the challenges facing exporters within this industry with special reference to selected sub-sectors. The challenges are approached from a supply chain perspective only. Problem Investigated: The research problem of this study was to identify these unique challenges and ascertain whether the implementation of a 'philosophy of continuous improvement' could be used as a strategic tool to address the challenges they face in the market. Methodology: This study included a combination of literature review, interviews with managers in the selected sub-groups and questionnaires sent out to determine the challenges facing automotive component exporters. In order to test the content validity and the reliability of the questionnaire, a pilot study was conducted at two organisations that are the main suppliers of automotive filters for passenger vehicles. The non-probability convenience sample technique was used to select the sample and consisted of selected sub-sectors that contribute 64,1% of the total value of automotive component exports in South Africa. Out of twenty-seven questionnaires sent out, twenty (74% response rate were duly completed by the respondents and returned to the researcher. Findings: South Africa faces unique challenges and these are listed and ranked according to priority from most to least important as follows: 1. The reduction of production costs; 2. R/US$ exchange rate effect on the respondent's export sales and profit margin; 3. Exchange rate fluctuations; 4. Threats to the local automotive component market; and 5. Increased competition by way of manufactured imports being sold in the South African market. Value of Research: The study provides recommendations that can be used within the automotive component industry.

Modelling zirconium hydrides using the special quasirandom structure approach

KAUST Repository

Wang, Hao; Chroneos, Alexander I.; Jiang, Chao; Schwingenschlö gl, Udo

2013-01-01

The study of the structure and properties of zirconium hydrides is important for understanding the embrittlement of zirconium alloys used as cladding in light water nuclear reactors. Simulation of the defect processes is complicated due to the random distribution of the hydrogen atoms. We propose the use of the special quasirandom structure approach as a computationally efficient way to describe this random distribution. We have generated six special quasirandom structure cells based on face centered cubic and face centered tetragonal unit cells to describe ZrH2-x (x = 0.25-0.5). Using density functional theory calculations we investigate the mechanical properties, stability, and electronic structure of the alloys. © the Owner Societies 2013.

Wave transport in the South Australian Basin

Science.gov (United States)

Bye, John A. T.; James, Charles

2018-02-01

The specification of the dynamics of the air-sea boundary layer is of fundamental importance to oceanography. There is a voluminous literature on the subject, however a strong link between the velocity profile due to waves and that due to turbulent processes in the wave boundary layer does not appear to have been established. Here we specify the velocity profile due to the wave field using the Toba spectrum, and the velocity profile due to turbulence at the sea surface by the net effect of slip and wave breaking in which slip is the dominant process. Under this specification, the inertial coupling of the two fluids for a constant viscosity Ekman layer yields two independent estimates for the frictional parameter (which is a function of the 10 m drag coefficient and the peak wave period) of the coupled system, one of which is due to the surface Ekman current and the other to the peak wave period. We show that the median values of these two estimates, evaluated from a ROMS simulation over the period 2011-2012 at a station on the Southern Shelf in the South Australian Basin, are similar in strong support of the air-sea boundary layer model. On integrating over the planetary boundary layer we obtain the Ekman transport (w*2/f) and the wave transport due to a truncated Toba spectrum (w*zB/κ) where w* is the friction velocity in water, f is the Coriolis parameter, κ is von Karman's constant and zB = g T2/8 π2 is the depth of wave influence in which g is the acceleration of gravity and T is the peak wave period. A comparison of daily estimates shows that the wave transports from the truncated Toba spectrum and from the SWAN spectral model are highly correlated (r = 0.82) and that on average the Toba estimates are about 86% of the SWAN estimates due to the omission of low frequency tails of the spectra, although for wave transports less than about 0.5 m2 s-1 the estimates are almost equal. In the South Australian Basin the Toba wave transport is on average about 42% of

Since the mid-2000s, the practice of South-South cooperation in health (SSC) has attracted growing attention among policymakers, health and foreign affairs ministries, global health agencies, and scholars from a range of fields. But the South-South label elucidates little about the actual content of the cooperation and conflates the "where" with the "who, what, how, and why". While there have been some attempts to theorize global health diplomacy and South-South cooperation generally, these efforts do not sufficiently distinguish among the different kinds of practices and political values that fall under the South-South rubric, ranging from economic and geopolitical interests to social justice forms of solidarity. In the spirit of deepening theoretical, historical, and social justice analyses of SSC, this article: (1) critically revisits international relations theories that seek to explain SSC, exploring Marxian and other heterodox theories ignored in the mainstream literature; (2) traces the historical provenance of a variety of forms of SSC; and (3) introduces the concept of social justice-oriented South-South.

2013-12-01

Stem cells have received much attention globally due in part to the immense therapeutic potential they harbor. Unfortunately, malpractice and exploitation (financial and emotional) of vulnerable patients have also drawn attention to this field as a result of the detrimental consequences experienced by some individuals that have undergone unproven stem cell therapies. South Africa has had limited exposure to stem cells and their applications and, while any exploitation is detrimental to the field of stem cells, South Africa is particularly vulnerable in this regard. The current absence of adequate legislation and the inability to enforce existing legislation, coupled to the sea of misinformation available on the Internet could lead to an increase in illegitimate stem cell practices in South Africa. Circumstances are already precarious because of a lack of understanding of concepts involved in stem cell applications. What is more, credible and easily accessible information is not available to the public. This in turn cultivates fears born out of existing superstitions, cultural beliefs, rituals and practices. Certain cultural or religious concerns could potentially hinder the effective application of stem cell therapies in South Africa and novel ways of addressing these concerns are necessary. Understanding how scientific progress and its implementation will affect each individual and, consequently, the community, will be of cardinal importance to the success of the fields of stem cell therapy and regenerative medicine in South Africa. A failure to understand the ethical, cultural or moral ramifications when new scientific concepts are introduced could hinder the efficacy and speed of bringing discoveries to the patient. Neglecting proper procedure for establishing the field would lead to long delays in gaining public support in South Africa. Understanding the dangers of stem cell tourism - where vulnerable patients are subjected to unproven stem cell therapies that

Full Text Available In a general sense, competence represents a higher finality which ensures the transfer of acquired theoretical knowledge to effective teaching practices. In the teaching profession, there are three types of competences: professional (they show the teacher's theoretical knowledge, psycho-pedagogical (they concern the teacher's ability to know their students and to establish interhuman relationships with them and methodical (concerns the teacher's ability to teach effectively the elements of the didactic content. Due to the particularities of special / inclusive education, teachers involved in this form of education should possess mainly psycho-pedagogical and methodical competences so that they can meet successfully the educational needs of students with disabilities. The aim of the research was to identify the psycho-pedagogical and methodical competences of special / inclusive education teachers, as well as ways to improve them using continued professional training activities. The sample consisted of 225 teachers, who work in various forms of special education in Bihor County, Romania. The instrument consisted of a questionnaire with 21 items. The research was conducted in April 2017. The results of the research showed that special education teachers are more empathetic and use a more diversified range of didactic strategies, while inclusive education teachers are concerned with continued professional training in the field of special education.

Full Text Available The source and sinks of carbon dioxide (CO₂ and methane (CH₄ due to anthropogenic and natural biospheric activities were estimated for the South Asian region (Bangladesh, Bhutan, India, Nepal, Pakistan and Sri Lanka. Flux estimates were based on top-down methods that use inversions of atmospheric data, and bottom-up methods that use field observations, satellite data, and terrestrial ecosystem models. Based on atmospheric CO₂ inversions, the net biospheric CO₂ flux in South Asia (equivalent to the Net Biome Productivity, NBP was a sink, estimated at −104 ± 150 Tg C yr⁻¹ during 2007–2008. Based on the bottom-up approach, the net biospheric CO₂ flux is estimated to be −191 ± 193 Tg C yr⁻¹ during the period of 2000–2009. This last net flux results from the following flux components: (1 the Net Ecosystem Productivity, NEP (net primary production minus heterotrophic respiration of −220 ± 186 Tg C yr⁻¹ (2 the annual net carbon flux from land-use change of −14 ± 50 Tg C yr⁻¹, which resulted from a sink of −16 Tg C yr⁻¹ due to the establishment of tree plantations and wood harvest, and a source of 2 Tg C yr⁻¹ due to the expansion of croplands; (3 the riverine export flux from terrestrial ecosystems to the coastal oceans of +42.9 Tg C yr⁻¹; and (4 the net CO₂ emission due to biomass burning of +44.1 ± 13.7 Tg C yr⁻¹. Including the emissions from the combustion of fossil fuels of 444 Tg C yr⁻¹ for the 2000s, we estimate a net CO₂ land–atmosphere flux of 297 Tg C yr⁻¹. In addition to CO₂, a fraction of the sequestered carbon in terrestrial ecosystems is released to the atmosphere as CH₄. Based on bottom-up and top-down estimates, and chemistry-transport modeling, we estimate that 37 ± 3.7 Tg C yr⁻¹

Full Text Available The Fusarium fungi produce toxic substances called mycotoxins, which can cause disease and harmful effects in grains, livestock, and humans. Deoxynivalenol (DON, also known as vomitoxin, is one of the Fusarium mycotoxins that is known to cause vomiting in livestock. This study shows the occurrence of deoxynivalenol in feedstuffs (compound feed and feed ingredients between 2009 and 2016 in South Korea. A total of 653 domestic samples were collected at five time points, including 494 compound feed samples and 159 feed ingredient samples. DON contamination levels were analyzed using high-performance liquid chromatography (HPLC with pretreatment using an immunoaffinity column (IAC. The limit of detection (LOD and the limit of quantification (LOQ were estimated at 1–10 µg/kg and 3–35 µg/kg, respectively. Two compound feeds (two gestating sow feed samples out of 160 pig feed samples exceeded the European Commission (EC guidance value, while no feed ingredient samples exceeded the EC or South Korean guidance values. There were statistically significant differences in the mean contamination levels of compound feed and feed ingredients that indicated a decreasing trend over time.

Full Text Available Job satisfaction is an attitude that employees have about their work and is based on numerous factors, both intrinsic and extrinsic to the individual. Job satisfaction is important from the perspective of maintaining and retaining the appropriate employees within the organization, it is about fitting the right person to the right job in the right culture and keeping them satisfied. Job satisfaction at salesforce level has become a topic of growing concern since significant proportion of marketing budgets, especially in harmaceutical industry of South Africa, is spent on them to achieve the assigned targets in the circular market. Although a large number of studies have been conducted to investigate job satisfaction in diverse range of the cultures, subjects and occupations yet none has attempted to explore the impact of job content and context factors on the job satisfaction among pharmaceutical salespersons in South Africa. Thus, the current study intends to determine the variance in salespersons’ overall job satisfaction through job content and context factors as a whole. This study also extends the total repercussion on the sales persons and their satisfaction level that cement the good will of the company and personal upliftment.

There is little published literature on the ethical concerns of stakeholders in HIV vaccine trials. This study explored the ethical challenges identified by various stakeholders, through an open-ended, in-depth approach. While the few previous studies have been largely quantitative, respondents in this study had the opportunity to spontaneously identify the issues that they perceived to be of priority concern in the South African context. Stakeholders spontaneously identified the following as ethical priorities: informed consent, social harms, collaborative relationships between research stakeholders, the participation of children and adolescents, access to treatment for participants who become infected with HIV, physical harms, fair participant and community selection, confidentiality, benefits, and payment. While there is some speculation that research in developing countries poses special ethical challenges, overall no issues were identified that have not been anticipated in international guidance, literature and popular frameworks. However, the South African context affords a distinctive gloss to these expected issues; for example, respondents were concerned that the predominant selection of black participants may perpetuate racist practices of apartheid. Stakeholders should be aware of contextual factors impacting on the implementation of ethical principles. We make a series of recommendations for South African trials, including amendments to the ethical-legal framework and research policies, and, for further research.

2005-12-01

Full Text Available The perturbations caused by the Sun and the Moon are predominantly out-of-plane effects causing a change in the inclination and in the right ascension of ascending node of a geostationary satellite. Due to the change of the inclination, subsatellite latitude of the geostationary satellite has a daily variations of the same magnitude of the inclination. Therefore we need a facility to control the orbital inclination and right ascension of ascending node for maintaining the satellite position in specified subsatellite latitude boundary using thrusters. In this paper we studied North-South station keeping strategies of the COMS-1 such as Track-Back Chord Target (TBCT method, Maximum Compensation Target (MCT method and Minimum Fuel Target (MFT method. We accomplished those North-South station keeping maneuvers for one year starting from December 2008. The required velocity increments to maintain the satellite are estimated as MCT 52.6065m/s, TBCT 52.2383m/s, MFT 51.5428m/s, respectively. We demonstrated that TBCT and MFT methods are proper to North-South station keeping for COMS-1. MFT method showed the minimum required velocity increments whereas TBCT traced narrow inclination boundary area for North-South station keeping.

2010-06-01

Simulation of defect interactions in binary/ternary group IV semiconductor alloys at the density functional theory level is difficult due to the random distribution of the constituent atoms. The special quasirandom structures approach is a computationally efficient way to describe the random nature. We systematically study the efficacy of the methodology and generate a number of special quasirandom cells for future use. In order to demonstrate the applicability of the technique, the electronic structures of E centers in Si1-xGex and Si1-x -yGexSny alloys are discussed for a range of nearest neighbor environments. © 2010 Elsevier B.V.

2014-11-01

Full Text Available Counterparty valuation adjustment (CVA risk accounts for losses due to the deterioration in credit quality of derivative counterparties with large credit spreads. Of the losses attributed to counterparty credit risk incurred during the financial crisis of 2008-9 were due to CVA risk; the remaining third were due to actual defaults. Regulatory authorities have acknowledged and included this risk in the new Basel III rules. The capital implications of CVA risk in the South African milieu are explored, as well as the sensitivity of CVA risk components to market variables. Proposed methodologies for calculating changes in CVA are found to be unstable and unreliable at high average spread levels.

Understanding our present day carbon cycle and possible solutions to recent increases in atmospheric carbon dioxide is dependent upon quantifying the terrestrial carbon budget. Currently, global land cover and land use change is estimated to emit 0.9 PgC yr-1 compared to emissions due to fossil fuel combustion and cement production of 8.4 PgC yr-1. South and Southeast Asia (India, Nepal, Bhutan, Bangladesh, Burma, Thailand, Laos, Vietnam, Cambodia, Malaysia, Philippines, Indonesia, Pakistan, Myanmar, and Singapore) is a region of rapid land cover and land use change due to the continuous development of agriculture, deforestation, reforestation, afforestation, and the increased demand of land for people to live. In this study, we synthesize outputs of nine models participated in Global Carbon Budget Project to identify the carbon budget of South and southeast Asia, diagnose the contribution of land cover and land use change to carbon emissions and assess areas of uncertainty in the suite of models. Uncertainty is determined using the standard deviation and the coefficient of variation of net ecosystem exchange and its component parts. Results show the region's terrestrial biosphere was a source of carbon emissions from the 1980 to the early 1990s. During the same time period, land cover and land use change increasingly contributed to carbon emission. In the most recent two decades, the region became a carbon sink since emission due to land cover land use changes. Spatially, the greatest total emissions occurred in the tropical forest of Southeast Asia. Additionally, this is the subregion with the greatest uncertainty and greatest biomass. Model uncertainty is shown to be proportional to total biomass. The atmospheric impacts of ENSO are shown to suppress the net biosphere productivity in South and Southeast Asia leading to years of increased carbon emissions.

Cultural and biological particulars existing in East Asian countries are likely to mediate differences in the alcohol consumption experience. Despite this no research to date has directly explored the alcohol free association or expectancy of any East Asian nations. The current research aims to provide a set of South Korean alcohol expectancies. Two hundred and thirty-seven South Koreans participated in an alcohol free association test and completed a demographic survey. The results both confirmed and contradicted areas of past alcohol expectancy research. There appears to be differences in associates with high probability of recall and alcohol expectancy, where negative, negative sedating and sedating expectancy categories were not found to be predictors of South Korean drinker level. The results suggest that South Koreans have a more even level of negative expectancy across all drinker categories, possibly due to a combination of linguistic, cultural and biological difference found among this population. The results provide a list of South Korean alcohol free association norms for future alcohol research in the region, with the results also underlining the need for alcohol free association tests among East Asian nations. © 2011 Australasian Professional Society on Alcohol and other Drugs.

Salmonellosis is a significant cause of foodborne gastroenteritis in Australia, and rates of illness have increased over recent years. We adopt a Bayesian source attribution model to estimate the contribution of different animal reservoirs to illness due to Salmonella spp. in South Australia between 2000 and 2010, together with 95% credible intervals (CrI). We excluded known travel associated cases and those of rare subtypes (fewer than 20 human cases or fewer than 10 isolates from included sources over the 11-year period), and the remaining 76% of cases were classified as sporadic or outbreak associated. Source-related parameters were included to allow for different handling and consumption practices. We attributed 35% (95% CrI: 20-49) of sporadic cases to chicken meat and 37% (95% CrI: 23-53) of sporadic cases to eggs. Of outbreak-related cases, 33% (95% CrI: 20-62) were attributed to chicken meat and 59% (95% CrI: 29-75) to eggs. A comparison of alternative model assumptions indicated that biases due to possible clustering of samples from sources had relatively minor effects on these estimates. Analysis of source-related parameters showed higher risk of illness from contaminated eggs than from contaminated chicken meat, suggesting that consumption and handling practices potentially play a bigger role in illness due to eggs, considering low Salmonella prevalence on eggs. Our results strengthen the evidence that eggs and chicken meat are important vehicles for salmonellosis in South Australia. © 2015 Society for Risk Analysis.

This paper brings a discussion about the challenges involved in the development of a new kind of nuclear facility in Brazil, a naval base for nuclear submarines, with attention to the licensing process and considerations about the risk-informed decision making application to the licensing process. Initially, a model of such a naval base, called in this work, special industrial facility, is proposed, with its systems and respective sets of basic requirements, in order to make it possible the accomplishment of the special industrial facility support function to the nuclear submarine. A discussion about current challenges to overcome in this project is presented: the challenges due to the new characteristics of this type of nuclear facility; existence of several interfaces between the special industrial facilities systems and nuclear submarine systems in design activities; lack of specific regulation in Brazil to allow the licensing process of special industrial facilities by the nuclear safety authority; and comments about the lack of information from reference nuclear facilities, as is the case with nuclear power reactors (for example, the German Grafenrheinfeld nuclear plant is the reference plant for the Brazilian Angra 2 nuclear plant). Finally, in view of these challenges, an analysis method of special industrial facility operational scenarios to assist the licensing process is proposed. Also, considerations about the application of risk-informed decision making to the special industrial facility activity and licensing process in Brazil are presented. (author)

Koeppel, Katja N; Kemp, Lucy V

2015-12-01

The southern ground hornbill (Bucorvus leadbeateri) has been classified as globally vulnerable and, in South Africa, regionally endangered, with a negative population trend. Factors contributing to the population decline in South Africa are poisoning, electrocution, and illegal capture for trade, coupled with slow reproductive rates and extensive habitat requirements. Lead toxicosis is a previously undescribed threat for the population. An adult southern ground hornbill presented with acute lead toxicosis due to lead particles in the gizzard, which required intensive treatment. Two other hornbills were likely exposed. The source of the lead in these cases was likely a carcass of a porcupine that was killed with lead shot. This report highlights the importance of the use of lead-free ammunition within the habitat of the southern ground hornbill in South Africa.

This article describes the activities of the Greater Johannesburg Healthy Schools Program of the World Health Organization's (WHO) Healthy Cities Project in South Africa. Healthy Cities projects emphasize community participation, intersectoral action, supportive environments for health, and a settings approach. Children in South Africa, are exposed to environmental and health hazards in the school setting including poor building design, poor equipment, and understaffing. The Healthy Schools initiative in Greater Johannesburg, is a pilot for enhancing environmental quality, health, and well-being among students. Schools include those in an informal settlement in an industrial area, an inner city district, and in a suburban area. The initiative includes research, establishment of environmental and health committees, development of an action plan, and evaluation and feedback. The plan aims to promote environmental and health sustainability, to empower children to become full participants in the community, and to support teachers and parents in the promotion of health-enhancing school environments. The program builds upon the lessons learned from several local school initiatives. Initiatives include an anti-smoking poster competition involving over 10,000 students, special environmental and health awareness days, consciousness raising among high school students about air pollution, and local efforts to engage students in environmental clean-up days.

Due diligence duties for an environmental liability

International Nuclear Information System (INIS)

Huebsch, M.

2000-04-01

Jurisdiction turned out well to create a basic ruling for due diligence duties. These due diligence duties are high standards for the law of torts (outside of contracts) within the Austrian civil law and represent a liability-extension for the holder of the source of danger. They establish an action for injunction in particular for preventing (further) damages. Therewith due diligence duties get a general sense in the range of a civil law for environmental liability. The responsible holder of a danger zone will therefore influence his way of acting to protect potential victims and the environment. The burden of proof is on the plaintiff (victims) under the Civil Code. Victims have specific sources of danger including high endangering special facilities in their argumentation with the so-called prima-facie-proof or first-appearance-proof. A turning back of the presentation of evidence to the polluter is wrong. The polluter himself has a continuing liability for dangerous activities and his clerks in the case of an extremely high danger of damage. All due diligence duties can be arranged in three areas: in information-, danger-avoidance- and danger-prevention-duties. The determination of range and essence of the duties has to be adjusted to each individual case. The range of the specific danger area is the essential link. The intensity of due diligence duties is increasing with the size of danger in the way of a movable system depending on the protected interest. Due diligence duties have to be kept within reasonable limits with two criterions: necessarity and demand. Proportionality of actions is a third criterion to avoid exaggeration of due diligence duties to obtain an effective protection for victims including the environment. (author)

Modeling biomass burning over the South, South East and East Asian Monsoon regions using a new, satellite constrained approach

Science.gov (United States)

Lan, R.; Cohen, J. B.

2017-12-01

Biomass burning over the South, South East and East Asian Monsoon regions, is a crucial contributor to the total local aerosol loading. Furthermore, the impact of the ITCZ, and Monsoonal circulation patterns coupled with complex topography also have a prominent impact on the aerosol loading throughout much of the Northern Hemisphere. However, at the present time, biomass burning emissions are highly underestimated over this region, in part due to under-reported emissions in space and time, and in part due to an incomplete understanding of the physics and chemistry of the aerosols emitted in fires and formed downwind from them. Hence, a better understanding of the four-dimensional source distribution, plume rise, and in-situ processing, in particular in regions with significant quantities of urban air pollutants, is essential to advance our knowledge of this problem. This work uses a new modeling methodology based on the simultaneous constraints of measured AOD and some trace gasses over the region. The results of the 4-D constrained emissions are further expanded upon using different fire plume height rise and in-situ processing assumptions. Comparisons between the results and additional ground-based and remotely sensed measurements, including AERONET, CALIOP, and NOAA and other ground networks are included. The end results reveal a trio of insights into the nonlinear processes most-important to understand the impacts of biomass burning in this part of the world. Model-measurement comparisons are found to be consistent during the typical burning years of 2016. First, the model performs better under the new emissions representations, than it does using any of the standard hotspot based approaches currently employed by the community. Second, long range transport and mixing between the boundary layer and free troposphere contribute to the spatial-temporal variations. Third, we indicate some source regions that are new, either because of increased urbanization, or of

Special Relativity Corrections for Space-Based Lidars

RaoGudimetla, Venkata S.; Kavaya, Michael J.

1999-01-01

The theory of special relativity is used to analyze some of the physical phenomena associated with space-based coherent Doppler lidars aimed at Earth and the atmosphere. Two important cases of diffuse scattering and retroreflection by lidar targets are treated. For the case of diffuse scattering, we show that for a coaligned transmitter and receiver on the moving satellite, there is no angle between transmitted and returned radiation. However, the ray that enters the receiver does not correspond to a retroreflected ray by the target. For the retroreflection case there is misalignment between the transmitted ray and the received ray. In addition, the Doppler shift in the frequency and the amount of tip for the receiver aperture when needed are calculated, The error in estimating wind because of the Doppler shift in the frequency due to special relativity effects is examined. The results are then applied to a proposed space-based pulsed coherent Doppler lidar at NASA's Marshall Space Flight Center for wind and aerosol backscatter measurements. The lidar uses an orbiting spacecraft with a pulsed laser source and measures the Doppler shift between the transmitted and the received frequencies to determine the atmospheric wind velocities. We show that the special relativity effects are small for the proposed system.

A practical approach to the nutritional management of chronic kidney disease patients in Cape Town, South Africa.

Science.gov (United States)

Ameh, Oluwatoyin I; Cilliers, Lynette; Okpechi, Ikechi G

2016-07-08

The multi-racial and multi-ethnic population of South Africa has significant variation in their nutritional habits with many black South Africans undergoing a nutritional transition to Western type diets. In this review, we describe our practical approaches to the dietary and nutritional management of chronic kidney disease (CKD) patients in Cape Town, South Africa. Due to poverty and socio-economic constraints, significant challenges still exist with regard to achieving the nutritional needs and adequate dietary counselling of many CKD patients (pre-dialysis and dialysis) in South Africa. Inadequate workforce to meet the educational and counselling needs of patients, inability of many patients to effectively come to terms with changing body and metabolic needs due to ongoing kidney disease, issues of adherence to fluid and food restrictions as well as adherence to medications and in some cases the inability to obtain adequate daily food supplies make up some of these challenges. A multi-disciplinary approach (dietitians, nurses and nephrologists) of regularly reminding and educating patients on dietary (especially low protein diets) and nutritional needs is practiced. The South African Renal exchange list consisting of groups of food items with the same nutritional content has been developed as a practical tool to be used by dietitians to convert individualized nutritional prescriptions into meal plan to meet the nutritional needs of patients in South Africa. The list is currently utilized in counselling CKD patients and provides varied options for food items within the same group (exchangeable) as well as offering ease for the description of suitable meal portions (sizes) to our patients. Regular and continuous education of CKD patients by a multi-disciplinary team in South Africa enables our patients to meet their nutritional goals and retard CKD progression. The South African renal exchange list has proved to be a very useful tool in meeting this need.

Eocene Podocarpium (Leguminosae) from South China and its biogeographic implications.

Science.gov (United States)

Xu, Qingqing; Qiu, Jue; Zhou, Zhekun; Jin, Jianhua

2015-01-01

Podocarpium A. Braun ex Stizenberger is one of the most common legumes in the Neogene of Eurasia, including fossil fruits, seeds, leaves, and possible flower and pollen grains. This genus is not completely consistent with any extant genera according to gross morphological characters and poorly preserved cuticular structures reported in previous studies. The fossil pods collected from the coal-bearing series of the Changchang Basin of Hainan Island and Maoming Basin of Guangdong, South China, are examined by morphologically comparative work, with special reference to venation patterns and placental position. These distinctive features, as well as the ovule development of pods from different developmental stages and the epidermal structure of the pods, as distinguished from previous records lead to the conclusion that these fossils can be recognized as a new species of Podocarpium, P. eocenicum sp. nov. This new discovery indicates that Podocarpium had arrived in South China by the Eocene. Investigation on the fossil records of this extinct genus shows that P. eocenicum is the earliest and lowest latitude fossil data. The possible occurrence pattern of this genus is revealed as follows: Podocarpium had distributed in the South China at least in the middle Eocene, and then migrated to Europe during the Oligocene; in the Miocene this genus reached its peak in Eurasia, spreading extensively across subtropical areas to warm temperate areas; finally, Podocarpium shrank rapidly and became extinct in Eurasia during the Pliocene.

Sexual specialization in two tropical dioecious figs.

Science.gov (United States)

Patel, Aviva; McKey, Doyle

1998-07-01

Ficus species (figs) and their species-specific pollinator wasps are involved in an intimate mutualism in which wasps lay eggs in some ovaries of the closed inflorescences (syconia), and mature, inseminated offspring carry pollen from mature syconia to fertilize receptive inflorescences. In monoecious species, each syconium produces seeds and wasps. In functionally dioecious fig species, making up approximately half the figs worldwide, male and female functions are separated; hermaphrodite (functionally male) trees produce wasps and pollen only, while female trees produce seeds only. This sexual separation allows selection to act independently on the reproductive biology of each sex. Examining sexual specialization in a tight mutualism allows us to determine aspects of the mutualism that are flexible and those that are canalized. In this study, we quantified the phenology of two species of dioecious figs, F. exasperata and F. hispida, for 2 years by following the fates of several thousand syconia over time. In studying each of these species in a dry and a wet site in south India, we tested specific predictions of how dioecious figs might optimize sexual function. On female trees of both species, more inflorescences matured during the wet (monsoon) season than in any other season; this fruiting period enabled seeds to be produced during the season most suitable for germination. In F. exasperata, functionally male trees released most wasps from mature syconia in the dry season, during peak production of receptive female syconia, and thus maximized successful pollination. In F. hispida, "male" trees produced more syconia in the dry and monsoon seasons than in the post-monsoon season. In both species, male and female trees abscised more unpollinated, young inflorescences than pollinated inflorescences, but abscission appeared to be more likely due to resource- rather than pollinator- limitation. The phenology of F. exasperata requires that male inflorescences wait in

Full Text Available The South African Concise Oxford Dictionary (henceforth SACOD is a South Af-rican version of the Concise Oxford Dictionary, the first time that this particular hybrid has been prepared. It is testimony to the enduring success of the work of the Dictionary Unit for South African English at Rhodes University, headed by teams that included Jean and William Branford in the 1970s, Penny Silva in the 1990s and now, Kathryn Kavanagh. The lexicographical work from the unit saw the publication of four editions of the Dictionary of Southern African English (1978, 1980, 1987, 1991, a South African Pocket Oxford Dictionary (SAPOD and the Dictionary of South African English on Historical Principles (DOSAEHP (1995. SACOD differs from the rest in several ways. It is larger in scope than SAPOD, smaller than DOSAEHP, and unlike DOSAE and DOSAEHP, does not deal with South African words alone. Based on the 10th edition of the Concise Oxford Dictionary SACOD has excised some words from the parent, whilst adding many new words of general English as well as of South Africa.

This true-color image of South Africa was acquired on May 14, 2000, by NASA's Moderate-resolution Imaging Spectroradiometer, or MODIS. The image was produced using a combination of the sensor's 250-m and 500-m resolution visible wavelength bands. As part of the opening ceremony to begin the joint U.S.-South Africa SAFARI Field Experiment, NASA presented print copies of this image as GIFts to Dr. Ben Ngubane, Minister of Arts, Science and Technology, and Honorable Advocate Ngoaka Ramathlodi, Premier of the Northern Province, South Africa. The area shown in this image encompasses seven capital cities and a number of the region's distinctive geological features can be seen clearly. Toward the northern (top) central part of the image, the browns and tans comprise the Kalahari Desert of southern Botswana. The Tropic of Capricorn runs right through the heart of the Kalahari and the Botswanan capital city of Gaborone sits on the Limpopo River, southeast of the Kalahari. Along the western coastline of the continent is the country of Namibia, where the Namib Desert is framed against the sea by the Kaokoveld Mountains. The Namibian capital of Windhoek is obscured by clouds. Looking closely in the center of the image, the Orange River can be seen running from east to west, demarcating the boundary between Namibia and South Africa. On the southwestern corner of the continent is the hook-like Cape of Good Hope peninsula and Cape Town, the parliamentary capital of South Africa. Running west to east away from Cape Town are the Great Karroo Mountains. The shadow in this image conveys a sense of the very steep grade of the cliffs along the southern coast of South Africa. Port Elizabeth sits on the southeasternmost point of South Africa, and a large phytoplankton bloom can be seen in the water about 100 miles east of there. Moving northward along the east coast, the Drakensberg Mountains are visible. The two small nations of Lesotho and Swaziland are in this region, completely

Exploring perceptions of HIV risk and health service access among Zimbabwean migrant women in Johannesburg: a gap in health policy in South Africa?

Science.gov (United States)

Munyewende, Pascalia; Rispel, Laetitia C; Harris, Bronwyn; Chersich, Matthew

2011-01-01

We present qualitative data from a 2005 exploratory study, recently published studies, and an analysis of the Department of Health's strategic plan to highlight the need for a broader policy debate on health-care access for migrants in South Africa. We conducted in-depth interviews with 15 Zimbabwean women living in inner-city Johannesburg to document the special characteristics of this group of migrants, enquiring about their perceptions of HIV risk, and experiences of health services in South Africa. We identified access barriers, namely perceptions of relatively low HIV risk, severely constrained financial circumstances, uncertain legal status, and experiences of unresponsive health workers. We recommend that migrant-health rights be placed on South Africa's policy agenda, migrants be included in HIV prevention programs and that health workers be sensitized to the needs of migrants.

2018-03-01

Opening of the South China Sea and upwelling of the Hainan Plume are among the most challenging issues related to the tectonic evolution of East Asia. However, when and how the Hainan Plume affected the opening of the South China Sea remains unclear. Here we investigate the geochemical and isotopic features of the 25 Ma mid-ocean ridge basalt (MORB) in the Kenting Mélange, southern Taiwan, 16 Ma MORB drilled by the IODP Expedition 349, and 9 Ma ocean island basalt-type dredged seamount basalt. The 25 Ma MORBs reveal a less metasomatic depleted MORB mantle-like source. In contrast, the Miocene samples record progressive mantle enrichment and possibly signal the contribution of the Hainan Plume. We speculate that MORBs of the South China Sea which could have recorded plume-ridge source mixing perhaps appear since 23.8 Ma. On the contrary, the Paleocene-Eocene ocean island basalt-type intraplate volcanism of the South China continental margin is correlated to decompression melting of a passively upwelling fertile asthenosphere due to continental rifting.

The impact of the subtropical South Atlantic SST on South American precipitation

Directory of Open Access Journals (Sweden)

A. S. Taschetto

2008-11-01

Full Text Available The Community Climate Model (CCM3 from the National Center for Atmospheric Research (NCAR is used to investigate the effect of the South Atlantic sea surface temperature (SST anomalies on interannual to decadal variability of South American precipitation. Two ensembles composed of multidecadal simulations forced with monthly SST data from the Hadley Centre for the period 1949 to 2001 are analysed.

A statistical treatment based on signal-to-noise ratio and Empirical Orthogonal Functions (EOF is applied to the ensembles in order to reduce the internal variability among the integrations. The ensemble treatment shows a spatial and temporal dependence of reproducibility. High degree of reproducibility is found in the tropics while the extratropics is apparently less reproducible. Austral autumn (MAM and spring (SON precipitation appears to be more reproducible over the South America-South Atlantic region than the summer (DJF and winter (JJA rainfall. While the Inter-tropical Convergence Zone (ITCZ region is dominated by external variance, the South Atlantic Convergence Zone (SACZ over South America is predominantly determined by internal variance, which makes it a difficult phenomenon to predict. Alternatively, the SACZ over western South Atlantic appears to be more sensitive to the subtropical SST anomalies than over the continent.

An attempt is made to separate the atmospheric response forced by the South Atlantic SST anomalies from that associated with the El Niño – Southern Oscillation (ENSO. Results show that both the South Atlantic and Pacific SSTs modulate the intensity and position of the SACZ during DJF. Particularly, the subtropical South Atlantic SSTs are more important than ENSO in determining the position of the SACZ over the southeast Brazilian coast during DJF. On the other hand, the ENSO signal seems to influence the intensity of the SACZ not only in DJF but especially its oceanic branch during MAM. Both local and

Climate change is known to affect the human health both directly by increased heat stress and indirectly by altering environments, particularly by altering the rate of ambient ozone formation in the atmosphere. Thus, the risks of climate change may be underestimated if the effects of both future temperature and ambient ozone concentrations are not considered. This study presents a projection of future summer non-accidental mortality in seven major cities of South Korea during the 2020s (2016-2025) and 2050s (2046-2055) considering changes in temperature and ozone concentration, which were predicted by using the HadGEM3-RA model and Integrated Climate and Air Quality Modeling System, respectively. Four Representative Concentration Pathway (RCP) scenarios (RCP 2.6, 4.5, 6.0, and 8.5) were considered. The result shows that non-accidental summer mortality will increase by 0.5%, 0.0%, 0.4%, and 0.4% in the 2020s, 1.9%, 1.5%, 1.2%, and 4.4% in the 2050s due to temperature change compared to the baseline mortality during 2001-2010, under RCP 2.6, 4.5, 6.0, and 8.5, respectively, whereas the mortality will increase by 0.0%, 0.5%, 0.0%, and 0.5% in the 2020s, and 0.2%, 0.2%, 0.4%, and 0.6% in the 2050s due to ozone concentration change. The projection result shows that the future summer morality in South Korea is increased due to changes in both temperature and ozone, and the magnitude of ozone-related increase is much smaller than that of temperature-related increase, especially in the 2050s.

After decades of unawareness about Lynch syndrome, the medical community in South America is increasingly interested and informed. The visits and support of mentors like H. T. Lynch had been crucial to this awakening. Several countries have at least one registry with skilled personnel in genetic counseling and research. However, this only represents a very restricted resource for the region. According to the GETH, there are 27 hereditary cancer care centers in South America (21 in Brazil, 3 in Argentina, 1 in Uruguay, 1 in Chile and 1 in Peru). These registries differ in fundamental aspects of function, capabilities and funding, but are able to conduct high quality clinical, research and educational activities due to the dedication and personal effort of their members, and organizational support. More support from the governments as well as the participation of the community would boost the initiatives of people leading these groups. Meantime, the collaboration among the South American registries and the involvement of registries and leaders from developed countries will allow to maximize the efficiency in caring for affected patients and their families. The aim of this article is to describe how the knowledge of LS began to be spread in South America, how the first registries were organized and to summarize the current state of progress. In addition, we will provide an update of the clinical and molecular findings in the region.

''Special frequencies'' have been asserted to be zeros of the density of frequencies corresponding to a random chain of coupled oscillators. Our investigation includes both this model and the random one-dimensional Schroedinger operator describing an alloy or its discrete analogue. Using the phase method we exactly determine a bilateral Lifsic asymptotic of the integrated density of states k(E) at special energies G s , which is not only of the classical type exp(-c/vertical strokeE-E s vertical stroke 1/2 ) but also exp(-c'/vertical strokeE-E s vertical stroke) is a typical behaviour. In addition, other asymptotics occur, e.g. vertical strokeE-E c vertical stroke c '', which show that k(E) need not be C ∞ . (orig.)

THE INCORPORATION OF DOUBLE TAXATION AGREEMENTS INTO SOUTH AFRICAN DOMESTIC LAW

Directory of Open Access Journals (Sweden)

Izelle du Plessis

2015-11-01

Full Text Available There are different opinions as to the process whereby double taxation agreements (DTAs are incorporated into South African law. This contribution aims to discuss some of the existing opinions and to offer a further perspective on the matter. At the heart of the debate lies the interpretation of two provisions, namely section 231 of the Constitution of the Republic of South Africa and section 108 of the Income Tax Act and the interaction between the two. This contribution argues that South Africa's DTAs are not self-executing (a term referred to in section 231(4 of the Constitution and should therefore be enacted into law by national legislation. It is furthermore argued that section 108(2 of the Income Tax Act enables a DTA to be incorporated into South African domestic law, by means of publication in the Government Gazette. An analysis of the case law supports this argument. Whether or not DTAs are regarded as self-executing, the status of a DTA in relation to the Income Tax Act still has to be determined. In other words, once the DTA forms part of South African domestic law, does it rank higher, lower or on a par with the Income Tax Act? It is submitted that the status of DTAs in South Africa is determined by the Constitution. It is furthermore submitted that South Africa's DTAs do not attain a status on the same level as the Constitution and that the Constitution allows for the possibility that South Africa's DTAs may be overridden by subsequent legislation (for example, by amendments to the Income Tax Act. Whether or not an override will take place in a specific case should, it is submitted, be determined by the application of the principles of statutory interpretation which apply in the case of conflict. Although this latter submission finds support in the minority judgement in Glenister, both the AM Moolla and Tradehold decisions express contrary views. The hope is expressed that the South African courts will provide clarity on this

2010-12-01

Full Text Available The present paper delivers an analysis and a systematization of the Brazilian legislation (from the nineteenth century to the year 2009 regarding the education of disabled people, as well as their rights and the services meant to support them. This research, which is based on collected data from relevant literature and documents, reviews the historical process of the trajectory of the Special Education in Brazil. The study indicates that educational policies in Brazil have identified the Special Education students differently over time. The teaching of students with disabilities or who failed to adapt themselves to regular education was offered separately from the common education. Due to the advancements on studies and research in the fields of Education and Human Rights, educational laws and practices began to change, which prompted the need of a reorganization of both the common schools and the special schools.

Further morphological evidence on South African earliest Homo lower postcanine dentition: Enamel thickness and enamel dentine junction.

2016-07-01

The appearance of the earliest members of the genus Homo in South Africa represents a key event in human evolution. Although enamel thickness and enamel dentine junction (EDJ) morphology preserve important information about hominin systematics and dietary adaptation, these features have not been sufficiently studied with regard to early Homo. We used micro-CT to compare enamel thickness and EDJ morphology among the mandibular postcanine dentitions of South African early hominins (N = 30) and extant Homo sapiens (N = 26), with special reference to early members of the genus Homo. We found that South African early Homo shows a similar enamel thickness distribution pattern to modern humans, although three-dimensional average and relative enamel thicknesses do not distinguish australopiths, early Homo, and modern humans particularly well. Based on enamel thickness distributions, our study suggests that a dietary shift occurred between australopiths and the origin of the Homo lineage. We also observed that South African early Homo postcanine EDJ combined primitive traits seen in australopith molars with derived features observed in modern human premolars. Our results confirm that some dental morphological patterns in later Homo actually occurred early in the Homo lineage, and highlight the taxonomic value of premolar EDJ morphology in hominin species.

A comparative perspective on teacher attitude-constructs that impact on inclusive education in South Africa and Sweden

Directory of Open Access Journals (Sweden)

Norma Nel

2011-01-01

Full Text Available This article is based on joint research, between academics from South Africa and Sweden, comparing the influence of South African and Swedish teachers' attitudes towards the practical application of inclusive education (IE in the classroom. The aim of the study was to identify and investigate problem areas pertaining to teachers' attitudes to IE. Attitudes often relate to interaction with others. This study departs from Festiger's theory of cognitive dissonance, which deals with the influence of people's attitudes and attitude change. In this research teachers from South Africa and Sweden completed the same questionnaire on perceptions pertaining to IE in their school system. A number of attitude-constructs were derived from the data via exploratory factor analysis methodology. Attitude-constructs included policy issues and specialised support; practical implementation of IE; teacher support structures; teachers' receptiveness of IE implementation; feasibility of proposed IE practices; and role of special schools in an IE environment. Negative responses to some of the attitude constructs identified problem areas in Swedish and South African inclusive systems. The comparative nature of the work enabled the researchers to suggest remedial action within each country'ssocio-economic setting, and in this way affect change in teacher attitudes.

CONCENTRATIONS OF INDICATOR ORGANISMS IN THE STORED RAINWATER IN THE MAKANA MUNICIPALITY, SOUTH AFRICA

ROMAN TANDLICH

2012-03-01

Full Text Available Concentrations of indicator organisms in the stored rainwater in the Makana Municipality, South Africa. The United Nations Millennium Development Goals’ target 7C seeks to halve the number of people without sustainable access to safe drinking water and basic sanitation by 2015. At present, supply of safe drinking water is still intermittent in some parts of South Africa due to infrastructural problems and droughts. Rainwater harvesting could be a solution to this problem. Microbial rainwater quality was evaluated in the Makana Municipality, South Africa. Enumerations were done using the membrane-filtration technique with m-FC and m-Endo agar and the indole test. One sample contained E. coli at 1 colony-forming unit/100 cm3, while the faecal coliform concentrations ranged from 0 to 98 colony-forming units/100 cm3 in all samples. The total coliform concentrations ranged from 0 to 200 colony-forming units/100 cm3. On-site treatment of rainwater was insufficient due to missing first-flush devices. Rainwater is suitable for subsurface irrigation of vegetable gardens. Strategies are required to involve the community in the design and building of new rainwater harvesting systems.

Restriction of television food advertising in South Korea: impact on advertising of food companies.

2013-03-01

The association between exposure to television (TV) food advertising and children's dietary habits has been well established in previous studies. However, the efficacy of restrictions on TV food advertising in the prevention of childhood obesity remains controversial. The South Korean government has recently enforced a regulation, termed the Special Act on Safety Management of Children's Dietary Life, which restricts TV advertising of energy-dense and nutrient-poor (EDNP) foods targeting children. This study aimed to determine the impact of this regulation by examining changes in the TV advertising practices of South Korean food companies since the scheduled enforcement date of January 2010. The total advertising budget, number of advertisement placements and gross rating points (GRPs) for advertisements on EDNP foods aired on the five representative TV channels in South Korea were compared and analyzed for the year before and after January 2010. After January 2010, the total adverting budget, number of advertisement placements and GRPs decreased during regulated hours. Even during non-regulated hours, a significant decline was noticed in the number of advertisement placements and GRPs. The total advertising budget for non-EDNP foods increased, whereas that for EDNP foods decreased at a higher rate in addition to a drop in its percentage share. These results suggest positive changes in TV advertising practices of food companies because of the regulation, thereby lowering children's exposure to TV advertising of EDNP foods and promoting a safer environment that may facilitate child health improvement in South Korea.

Alcohol Prices and Mortality Due to Liver Cirrhosis

Directory of Open Access Journals (Sweden)

2015-06-01

Full Text Available This study estimates a reduced-form regression model for mortality rates due to alcoholic liver diseases, with alcohol prices and income as explanatory variables. Panel data cover the years 2000-2010 for 21 member countries of the European Union. In the reduced form, prices affect mortality rates indirectly through the demand for alcohol, while income has potential direct and indirect effects. Country and time fixed effects are used to control for other factors that influence alcohol consumption and mortality. Special attention is paid to outliers in the data, and final results are based on the MS-estimator for robust regressions. Regression results for alcohol prices and income are sensitive to adjustments for stationary data and down-weighting of outliers and other influential data points. Final results indicate that alcohol prices do not affect mortality rates due to chronic liver diseases. Empirical results in the study do not lend support to broad price-based approaches to alcohol policy.

Coastal areas of South China face great challenges due to heavy metal contamination caused by rapid urbanization and industrialization. In this paper, more than 90 articles on levels, distributions, and sources of heavy metals in sediments and organisms were collected to review the status of heavy metal pollution along coastal regions of South China. The results show that heavy metal levels were closely associated with local economic development. Hong Kong and the Pearl River Estuary were severely contaminated by heavy metals. However, concentrations of heavy metals in sediments from Hong Kong have continually decreased since the early 1990 s. High levels of heavy metals were found in biota from Lingdingyang in Guangdong province. Mollusks had higher concentrations of heavy metals than other species. Human health risk assessments suggested that levels of heavy metals in some seafood from coastal areas of South China exceeded the safety limit. Copyright © 2013 Elsevier Ltd. All rights reserved.

Reforming the South African Social Security Adjudication System: Innovative Experiences from South African Non-Social Security Jurisdictions

Directory of Open Access Journals (Sweden)

Full Text Available There is currently no uniform social security dispute resolution system in South Africa due to the piecemeal fashion in which schemes were established or protection against individual risks regulated. The result is that each statute provides for its own dispute resolution institution(s and processes. There are also various gaps and challenges in the current social security dispute resolution systems, some of these relating to the uncoordinated and fragmented nature of the system; inaccessibility of some social security institutions; inappropriateness of some current appeal institutions; the lack of a systematic approach in establishing appeal institutions; a limited scope of jurisdiction and powers of adjudication institutions; inconsistencies in review and/or appeal provisions in various laws; an unavailability of alternative dispute resolution procedures; and an absence of institutional independence of adjudication institutions or forums. The system is therefore in need of reform. In developing an appropriate system, much can be learned from innovative experiences in comparative South African non-social security jurisdictions on the establishment of effective and efficient dispute resolution frameworks. Dispute resolution systems in the labour relations, business competition regulation and consumer protection jurisdictions have been established to realise the constitutional rights of their users (especially the rights of access to justice, to a fair trial and to just administrative action. They thus provide a benchmark for the development of the South African social security dispute resolution system.

Terrorism in South Korea.

South Korea has experienced > 30 suspected terrorism-related events since 1958, including attacks against South Korean citizens in foreign countries. The most common types of terrorism used have included bombings, shootings, hijackings, and kidnappings. Prior to 1990, North Korea was responsible for almost all terrorism-related events inside of South Korea, including multiple assassination attempts on its presidents, regular kidnappings of South Korean fisherman, and several high-profile bombings. Since 1990, most of the terrorist attacks against South Korean citizens have occurred abroad and have been related to the emerging worldwide pattern of terrorism by international terrorist organizations or deranged individuals. The 1988 Seoul Olympic Games provided a major stimulus for South Korea to develop a national emergency response system for terrorism-related events based on the participation of multiple ministries. The 11 September 2001 World Trade Center and Pentagon attacks and the 2001 United States of America (US) anthrax letter attacks prompted South Korea to organize a new national system of emergency response for terrorism-related events. The system is based on five divisions for the response to specific types of terrorist events, involving conventional terrorism, bioterrorism, chemical terrorism, radiological terrorism, and cyber-terrorism. No terrorism-related events occurred during the 2002 World Cup and Asian Games held in South Korea. The emergency management of terrorism-related events in South Korea is adapting to the changing risk of terrorism in the new century.

Soil organic carbon and physical properties in vegetable farms in South Uruguay

Garcia de Souza, M.; Dogliotti, S.; Alliaume, F.; Mancassola, V.

2011-01-01

The South of Uruguay is the area of the country most severely affected by soil erosion and where the most important vegetable production area is located. Soil degradation has been aggravated by a process of intensification and specialization of the vegetable production due to an unfavorable socio-economic context and lack of adequate planning of the production systems. The objectives of this work were the description of current soil quality (Typic Hapluderts, Paquic (vertic) Argiudolls, and Abruptic Argiudolls) in 16 vegetable farms in the region, and the evaluation of the impact of improved management techniques on soil quality. We evaluated soil organic carbon (SOC), soil structure stability and the evolution of SOC in time. We found a degradation of soil quality under vegetable cropping compared to the reference sites, given by an average loss of SOC of 31 to 44% and 0.4 mm in structure stability. A linear regression model was fitted to explain the change in SOC content observed in fields under vegetable cultivation during the period under study. The change in SOC content was explained by the organic matter inputs by green manures and chicken bed, the initial SOC content and length of the period in years. This model is a simple tool to estimate the effect of soil organic amendments on SOC balance in soils under vegetable cropping in this region

For past years, rice varieties cultivated in South Vietnam originated from domestic hybridisation or from IRRI. Rice mutation breeding has been initiated for recent years. To meet the requirement of rice production diversification in different agro-ecological areas and rice genetic resources, from 1993 Institute of Agricultural Science of South Vietnam has carried out rice improvement by induced mutation of radiation. The mutagen was gamma rays of 60 Co. The goal is to create inherited variations, which cannot be obtained from other breeding methods, specially important characters of rice varieties (high tolerance to acid sulfate soil, lodging resistance combined with early maturity), which were difficult to gain by hybridisation. With 60 Co gamma rays, doses of 10-20 krad, dose rate of 280 krad/h, dry and germinated seeds of introduced and local rice varieties (IR 64, IR 9729, IR 50404, IR 59606, Jasmine 85, Nang Huong, Tam Xoan) were irradiated. The irradiated seeds were immediately sown within 24 and 94 hrs for wet seeds and dry seeds after treatment, respectively. Population of 10,000-15,000 plants were established and evaluated by IRRI evaluation standard from M2-M7 generations. 365 lines, varieties were selected with better behaviours than original varieties as lodging resistance, earliness, potential yield, leaf characters, tolerant ability to adverse conditions etc. Some good varieties (VND95-19, VND95-20) have been approved as leading national varieties and released for large-scale production in South Vietnam.

Using the Labour of Special Squads in the Stalingrad Region in 1942-1945

Directory of Open Access Journals (Sweden)

Sergey G. Sidorov

2018-02-01

Full Text Available Special purpose camps for the NKVD of the USSR were established in 1941 to carry out a special inspection of former Red Army servicemen emerging from captivity or encirclement. In 1942 the labour of special squads started to be carried out at certain economic facilities of the country. The article deals with the issues related to the use of special forces in the Stalingrad region during the Great Patriotic War. The case of the Stalingrad region is interesting due to the fact that it showcases the overall evolution of the system of special camps, beginning with the creation of the first camps on December 28, 1941 by the Order of the NKVD of the USSR, and till their liquidation, which began in 1945. The Kamyshinsky special camp, which provided the workforce fo railway construction, was one of the first special camps in which forced labour of the special squads was used. Later, camp no. 018, which provided the workforce for restoration of the destroyed enterprises, was established in the region. The camp’s personnel worked mainly on the restoration of the Stalingrad Tractor Plant. The authors also study other regional objects on which special squads’ labour was used, as well as their organization and effectiveness. It is noted that the labour of highly qualified special squads was in demand in various sectors of the economy. The variable composition of special camps located on the territory of the Stalingrad region made a significant contribution to the restoration of the city and its major plants. This was promoted by the increasing literacy of labour organization, and by the improvement of the material supply of special camps. Special attention is paid to the transfer of the special squads to the permanent staff of industry. V.V. Shevchenko compiled the necessary sources and wrote the paper. S.G. Sidorov revealed some relevant sources, pointed out the conception and accomplished academic editing of the paper.

Developments in special geometry

2012-01-01

We review the special geometry of N = 2 supersymmetric vector and hypermultiplets with emphasis on recent developments and applications. A new formulation of the local c-map based on the Hesse potential and special real coordinates is presented. Other recent developments include the Euclidean version of special geometry, and generalizations of special geometry to non-supersymmetric theories. As applications we discuss the proof that the local r-map and c-map preserve geodesic completeness, and the construction of four- and five-dimensional static solutions through dimensional reduction over time. The shared features of the real, complex and quaternionic version of special geometry are stressed throughout.

The South African Society of Psychiatrists/Psychiatry Management Group management guidelines for adult attention-deficit/hyperactivity disorder

Directory of Open Access Journals (Sweden)

Renata Schoeman

2017-04-01

Full Text Available Disclaimer: These guidelines do not aim to provide a comprehensive review of all the pertinent literature comprising the evidence base and, as such, should be utilised in conjunction with other guidelines as well as the responsibility of practitioners to maintain a high level of personal knowledge and expertise. Despite the known efficacy of treatment and the substantial costs of untreated attention-deficit/hyperactivity disorder (ADHD, access to healthcare and treatment is not a given for many patients in South Africa (SA. In SA, there is poor identification and treatment of common mental disorders at primary healthcare level and limited access to specialist resources with a service delivery and treatment gap of up to 75%. Medication options are also often limited in emerging markets and in SA psychiatrists, and patients do not have access to the medication armamentarium available in established markets. Furthermore, the majority of South Africans currently utilise the public healthcare sector and may not have access to treatment options referred to in these guidelines. These guidelines should therefore not be seen as a policy document. The process: The South African Society of Psychiatrists’ Special Interest Group (SIG for adult ADHD was launched on 25 September 2015, with doctors Rykie Liebenberg and Renata Schoeman as convenor and co-convenor, respectively. The overall objective of the ADHD SIG is to improve the basket of care available to patients with ADHD. This is only possible through a combined and concerted effort of individuals with a special interest in and passion for ADHD to improve knowledge about and funding for the care of individuals with the disorder. One of the specific aims of the ADHD SIG was to develop South African guidelines for the diagnosis and treatment of adult ADHD specifically and update guidelines for the treatment of child, adolescent and adult ADHD.

Bhardwaj, P; Naja, M; Kumar, R; Chandola, H C

2016-03-01

The seasonal, interannual, and long-term variations in biomass burning activity and related emissions are not well studied over South Asia. In this regard, active fire location retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS), the retrievals of aerosol optical depth (AOD) from MODIS Terra, and tropospheric column NO2 from Ozone Monitoring Instrument (OMI) are used to understand the effects of biomass burning on the tropospheric pollution loadings over South Asia during 2003-2013. Biomass burning emission estimates from Global Fire Emission Database (GFED) and Global Fire Assimilation System (GFAS) are also used to quantify uncertainties and regional discrepancies in the emissions of carbon monoxide (CO), nitrogen oxide (NOx), and black carbon (BC) due to biomass burning in South Asia. In the Asian continent, the frequency of fire activity is highest over Southeast Asia, followed by South Asia and East Asia. The biomass burning activity in South Asia shows a distinct seasonal cycle that peaks during February-May with some differences among four (north, central, northeast, and south) regions in India. The annual biomass burning activity in north, central, and south regions shows an increasing tendency, particularly after 2008, while a decrease is seen in northeast region during 2003-2013. The increase in fire counts over the north and central regions contributes 24 % of the net enhancement in fire counts over South Asia. MODIS AOD and OMI tropospheric column NO2 retrievals are classified into high and low fire activity periods and show that biomass burning leads to significant enhancement in tropospheric pollution loading over both the cropland and forest regions. The enhancement is much higher (110-176 %) over the forest region compared to the cropland (34-62 %) region. Further efforts are required to understand the implications of biomass burning on the regional air quality and climate of South Asia.

Assessment of the impact of family physicians in the district health system of the Western Cape, South Africa

Directory of Open Access Journals (Sweden)

Meyer Swanepoel

2014-12-01

Full Text Available Background: In 2007, South Africa made family medicine a new speciality. Family physicians that have trained for this new speciality have been employed in the district health system since 2011. The aim of the present study was to explore the perceptions of district managers on the impact of family physicians on clinical processes, health system performance and health outcomes in the district health system (DHS of the Western Cape. Methods: Nine in-depth interviews were performed: seven with district managers and two with the chief directors of the metropolitan and rural DHS. Interviews were recorded, transcribed and analysed using the ATLAS-ti and the framework method. Results: There was a positive impact on clinical processes for HIV/AIDS, TB, trauma, noncommunicable chronic diseases, mental health, maternal and child health. Health system performance was positively impacted in terms of access, coordination, comprehensiveness and efficiency. An impact on health outcomes was anticipated. The impact was not uniform throughout the province due to different numbers of family physicians and different abilities to function optimally. There was also a perception that the positive impact attributed to family physicians was in the early stages of development. Unanticipated effects included concerns with their roles in management and training of students, as well as tensions with career medical officers. Conclusion: Early feedback from district managers suggests that where family physicians are employed and able to function optimally, they are making a significant impact on health system performance and the quality of clinical processes. In the longer term, this is likely to impact on health outcomes.

Efficient K+ buffering by mammalian retinal glial cells is due to cooperation of specialized ion channels.

Science.gov (United States)

Nilius, B; Reichenbach, A

1988-06-01

Radial glial (Müller) cells were isolated from rabbit retinae by papaine and mechanical dissociation. Regional membrane properties of these cells were studied by using the patch-clamp technique. In the course of our experiments, we found three distinct types of large K+ conducting channels. The vitread process membrane was dominated by high conductance inwardly rectifying (HCR) channels which carried, in the open state, inward currents along a conductance of about 105 pS (symmetrical solutions with 140 mM K+) but almost no outward currents. In the membrane of the soma and the proximal distal process, we found low conductance inwardly rectifying (LCR) channels which had an open state-conductance of about 60 pS and showed rather weak rectification. The endfoot membrane, on the other hand, was found to contain non-rectifying very high conductance (VHC) channels with an open state-conductance of about 360 pS (same solutions). These results suggest that mammalian Müller cells express regional membrane specializations which are optimized to carry spatial buffering currents of excess K+ ions.

Aggregate electricity demand in South Africa: Conditional forecasts to 2030

International Nuclear Information System (INIS)

Inglesi, Roula

2010-01-01

In 2008, South Africa experienced a severe electricity crisis. Domestic and industrial electricity users had to suffer from black outs all over the country. It is argued that partially the reason was the lack of research on energy, locally. However, Eskom argues that the lack of capacity can only be solved by building new power plants. The objective of this study is to specify the variables that explain the electricity demand in South Africa and to forecast electricity demand by creating a model using the Engle-Granger methodology for co-integration and Error Correction models. By producing reliable results, this study will make a significant contribution that will improve the status quo of energy research in South Africa. The findings indicate that there is a long run relationship between electricity consumption and price as well as economic growth/income. The last few years in South Africa, price elasticity was rarely taken into account because of the low and decreasing prices in the past. The short-run dynamics of the system are affected by population growth, too After the energy crisis, Eskom, the national electricity supplier, is in search for substantial funding in order to build new power plants that will help with the envisaged lack of capacity that the company experienced. By using two scenarios for the future of growth, this study shows that the electricity demand will drop substantially due to the price policies agreed - until now - by Eskom and the National Energy Regulator South Africa (NERSA) that will affect the demand for some years.

Sustainable freight transport in South Africa:Domestic intermodal solutions

Directory of Open Access Journals (Sweden)

Jan H. Havenga

2011-11-01

Full Text Available Due to the rapid deregulation of freight transport in South Africa two decades ago, and low historical investment in rail (with resultant poor service delivery, an integrated alternative to road and rail competition was never developed. High national freight logistics costs, significant road infrastructure challenges and environmental impact concerns of a road-dominated freight transport market have, however, fuelled renewed interest in intermodal transport solutions. In this article, a high-level business case for domestic intermodal solutions in South Africa is presented. The results demonstrate that building three intermodal terminals to connect the three major industrial hubs (i.e. Gauteng, Durban and Cape Town through an intermodal solution could reduce transport costs (including externalities for the identified 11.5 million tons of intermodalfriendly freight flows on the Cape and Natal corridors by 42% (including externalities.

Dynamics of the Water Circulations in the Southern South China Sea and Its Seasonal Transports.

Science.gov (United States)

Daryabor, Farshid; Ooi, See Hai; Samah, Azizan Abu; Akbari, Abolghasem

2016-01-01

A three-dimensional Regional Ocean Modeling System is used to study the seasonal water circulations and transports of the Southern South China Sea. The simulated seasonal water circulations and estimated transports show consistency with observations, e.g., satellite altimeter data set and re-analysis data of the Simple Ocean Data Assimilation. It is found that the seasonal water circulations are mainly driven by the monsoonal wind stress and influenced by the water outflow/inflow and associated currents of the entire South China Sea. The intrusion of the strong current along the East Coast of Peninsular Malaysia and the eddies at different depths in all seasons are due to the conservation of the potential vorticity as the depth increases. Results show that the water circulation patterns in the northern part of the East Coast of Peninsular Malaysia are generally dominated by the geostrophic currents while those in the southern areas are due solely to the wind stress because of negligible Coriolis force there. This study clearly shows that individual surface freshwater flux (evaporation minus precipitation) controls the sea salinity balance in the Southern South China Sea thermohaline circulations. Analysis of climatological data from a high resolution Regional Ocean Modeling System reveals that the complex bathymetry is important not only for water exchange through the Southern South China Sea but also in regulating various transports across the main passages in the Southern South China Sea, namely the Sunda Shelf and the Strait of Malacca. Apart from the above, in comparision with the dynamics of the Sunda Shelf, the Strait of Malacca reflects an equally significant role in the annual transports into the Andaman Sea.

Interaction between Digestive Strategy and Niche Specialization Predicts Speciation Rates across Herbivorous Mammals.

Science.gov (United States)

Tran, Lucy A P

2016-04-01

Biotic and abiotic factors often are treated as mutually exclusive drivers of diversification processes. In this framework, ecological specialists are expected to have higher speciation rates than generalists if abiotic factors are the primary controls on species diversity but lower rates if biotic interactions are more important. Speciation rate is therefore predicted to positively correlate with ecological specialization in the purely abiotic model but negatively correlate in the biotic model. In this study, I show that the positive relationship between ecological specialization and speciation expected from the purely abiotic model is recovered only when a species-specific trait, digestive strategy, is modeled in the terrestrial, herbivorous mammals (Mammalia). This result suggests a more nuanced model in which the response of specialized lineages to abiotic factors is dependent on a biological trait. I also demonstrate that the effect of digestive strategy on the ecological specialization-speciation rate relationship is not due to a difference in either the degree of ecological specialization or the speciation rate between foregut- and hindgut-fermenting mammals. Together, these findings suggest that a biological trait, alongside historical abiotic events, played an important role in shaping mammal speciation at long temporal and large geographic scales.

Several kinds of cattle and poultry fodder samples collected from South Valley University and Qena governorate farm, Qena, Upper Egypt were estimated for their natural radioactivity concentrations due to Ra-226, Ra-228, Th-232 and K-40 radionuclides. Twenty nine fodder samples were analyzed by using low-level gamma-spectrometric. Based on radionuclides concentrations in animal fodder and annual consumption rate, the human health risk from irradiation due to indirect ingestion can be assessed. The annual effective dose from these radionuclides, which may reach the local consumer through beef, milk, poultry and eggs consumption have been estimated as 2.7 E +00, 1.4 E +01, 1.0 E -01 and 1.4 E -01 μSv/y, respectively

South Asians are the third largest Asian group in the US and among the fastest growing racial groups in New Jersey. Tobacco consumption among South Asians is characterized by several smoked and smokeless tobacco products indigenous to the Indian subcontinent. However, there is a paucity of research on tobacco use behaviors among South Asians in the US. The goal of this study was to examine the awareness and use of South Asian tobacco products such as bidis, gutkha, paan, paan masala, and zarda as well as other potentially carcinogenic products such as supari, their context of use, and their cultural significance among South Asians living in the US. Eight focus groups were conducted with South Asian adults living in Central New Jersey. Overall, participants were aware of a wide variety of foreign and American tobacco products with older South Asians identifying a greater variety of indigenous products compared to younger South Asians. Hookah was consistently recognized as popular among the younger generation while products such as paan or paan masala were more commonly identified with elders. Use of tobacco-related products such as paan and supari were described as common at social gatherings or after meals. In addition, light or social users of South Asian tobacco products, including products not consistently defined as tobacco, may not report tobacco use on a survey. Better understanding of the use of these products among South Asians and how some may classify tobacco usage can inform future research and public health interventions in these communities.

Highlights: • Heavy metal contamination in coastal areas of South China has been reviewed. • Heavy metal levels were closely related to economic development in past decades. • Heavy metal levels from Hong Kong continually decreased from the early 1990s. • Higher concentrations of heavy metals were found in mollusk. • Levels of heavy metals in part of seafood exceeded the safety limit. -- Abstract: Coastal areas of South China face great challenges due to heavy metal contamination caused by rapid urbanization and industrialization. In this paper, more than 90 articles on levels, distributions, and sources of heavy metals in sediments and organisms were collected to review the status of heavy metal pollution along coastal regions of South China. The results show that heavy metal levels were closely associated with local economic development. Hong Kong and the Pearl River Estuary were severely contaminated by heavy metals. However, concentrations of heavy metals in sediments from Hong Kong have continually decreased since the early 1990s. High levels of heavy metals were found in biota from Lingdingyang in Guangdong province. Mollusks had higher concentrations of heavy metals than other species. Human health risk assessments suggested that levels of heavy metals in some seafood from coastal areas of South China exceeded the safety limit

Special relativity

Taylor, J.G.

1975-01-01

It is stated that the early chapters review special relativity from an elementary mathematical viewpoint, and include discussion of recent experiments which set out to test Einstein's predictions. The theory of relativity is then reformulated in more sophisticated mathematical language to show its relation to electro-magnetism, and to lay the foundation for more general viewpoints. The final chapter discusses in simple terms where activity in the field is currently centred, and where future interest lies. Chapter headings include: the constant speed of light; measuring time and distance; the Lorentz transformation (relativity of simultaneity, space-time and causality); relativistic kinematics (including - the Dopper effect); relativistic dynamics (including - nuclear binding energy, particle creation, electrodynamics); the structure of special relativity (including - the Lorentz group, the rotation group, elementary particle scattering); extensions of special relativity.

Despite South Africa's history of violent political conflict, and the link between stressful experiences and smoking in the literature, no public health study has examined South Africans' experiences of human rights violations and smoking. Using data from participants in the nationally representative cross-sectional South Africa Stress and Health study (SASH), this analysis examined the association between respondent smoking status and both human rights violations experienced by the respondent and violations experienced by the respondents' close friends and family members. SAS-Callable SUDAAN was used to construct separate log-binomial models by political affiliation during apartheid (government or liberation supporters). In comparison to those who reported no violations, in adjusted analyses, government supporters who reported violations of themselves but not others (RR = 1.76, 95% CI: 1.25-2.46) had a significantly higher smoking prevalence. In comparison to liberation supporters who reported no violations, those who reported violations of self only (RR = 1.56, 95%CI: 1.07-2.29), close others only (RR = 1.97, 95%CI: 1.12-3.47), or violations of self and close others due to close others' political beliefs and the respondent's political beliefs (RR = 2.86, 95%CI: 1.70-4.82) had a significantly higher prevalence of smoking. The results of this analysis suggest that a relationship may exist between human rights violations and smoking among South Africa adults. Future research should use longitudinal data to assess causality, test the generalizability of these findings, and consider how to apply these findings to smoking cessation interventions.

Photosynthetic pathways and the geographical distribution of grasses in South West Africa/Namibia

International Nuclear Information System (INIS)

Ellis, R.P.; Vogel, J.C.; Fuls, A.

1980-01-01

Analysis of floristic lists for South West Africa/Namibia shows that, throughout the territory, more than 95% of the grass species occurring in any given area display the C 4 photosynthetic pathway. Exceptions are areas in the north-east and southwest where between 5% and 18% of the grass species are of the C 3 type. The south-western district of Luderitz falls within the winter rainfall area and it is only here that temperate C 3 genera are found. The C 3 species in the north-east belong to tropical groups. Most of the South West African C 3 grasses grow in specialized habitats and are either hydrophytes or sciophytes. Subdivision of the C 4 grasses into the three subtypes of the C 4 pathway reveals distinctive distributional trends. Malate formers or NADP-me species clearly become more abundant with increasing rainfall, whereas the aspartate formers show the opposite tendency. However, within the aspartate forming group the results show that it is specifically the NAD-me type of species which dominate in areas of very low precipitation, notably in the Namib and pre-Namib areas where rainfall is less than 200 mm/yr. The PEP-ck species form a group intermediate between the malate formers and the NAD-me grasses, especially as far as their water requirements are concerned [af

The current research provides a method for tracking near-surface mass-density anomalies via using only land-based gravity data, which is based on a special version of Poisson's Partial Differential Equation (PDE) of the gravitational field at Earth's surface. The research demonstrates how the Poisson's PDE can provide us with a capability to extract the near-surface mass-density anomalies from land-based gravity data. Herein, this version of the Poisson's PDE is mathematically introduced to the Earth's surface and then it is used to develop the new method for approximating the mass-density via derivatives of the Earth's gravitational field (i.e. via the gradient tensor). Herein, the author believes that the PDE can give us new knowledge about the behavior of the Earth's gravitational field at the Earth's surface which can be so useful for developing new methods of Earth's mass-density determination. In a case study, the proposed method is applied to a set of gravity stations located in the south of Iran. The results were numerically validated via certain knowledge about the geological structures in the area of the case study. Also, the method was compared with two standard methods of mass-density determination. All the numerical experiments show that the proposed approach is well-suited for tracking near-surface mass-density anomalies via using only the gravity data. Finally, the approach is also applied to some petroleum exploration studies of salt diapirs in the south of Iran.

Business continuity, emergency planning and special needs: How to protect the vulnerable.

Science.gov (United States)

Reilly, Daniel

2015-01-01

Emergencies and disasters affect all segments of the population. Some segments are more at risk during the emergency response and recovery efforts owing to vulnerabilities that increase the risk of harm. These vulnerabilities are due to individuals' disabilities, which must be incorporated into emergency and business continuity planning. Some disabilities are obvious, such as impaired vision, hearing or mobility, while other are less evident, but equally disabling, such as cognitive disorders, geographical or language isolation, and numerous age-related factors. Taken together when creating emergency or business continuity plans, the issues identified as disabilities can be grouped by functionality and termed as special needs. This paper will detail the identification of special needs populations, explain how these persons are vulnerable during the emergency or disaster response and recovery process, and provide examples of how to partner with individuals within identified special needs populations to improve the planning process.

Special protective concretes

International Nuclear Information System (INIS)

Bouniol, P.

2001-01-01

Concrete is the most convenient material when large-scale radiation protection is needed. Thus, special concretes for nuclear purposes are used in various facilities like reactors, reprocessing centers, storage sites, accelerators, hospitals with nuclear medicine equipment, food ionization centers etc.. The recent advances made in civil engineering for the improvement of concrete durability and compactness are for a large part transposable to protection concretes. This article presents the basic knowledge about protection concretes with the associated typological and technological aspects. A large part is devoted to the intrinsic properties of concretes and to their behaviour in irradiation and temperature conditions: 1 - definition and field of application of special protective concretes; 2 - evolution of concepts and technologies (durability of structures, techniques of formulation, new additives, market evolution); 3 - design of protective structures (preliminary study, radiation characteristics, thermal constraints, damping and dimensioning, mechanical criteria); 4 - formulation of special concretes (general principles, granulates, hydraulic binders, pulverulent additives, water/cement ratio, reference composition of some special concretes); 5 - properties of special concretes (damping and thermo-mechanical properties); 6 - induced-irradiation and temperature phenomena (activation, radiolysis, mineralogical transformations, drying, shrinking, creep, corrosion of reinforcement).

Full Text Available The article presents the main results of the analysis of the agriculture automation level in Russia and in the world. The results of the research of the foreign market, structures and compositions of foreign-made unmanned mobile energy vehicles are presented. The main direction of development of foreign companies is the creation of new models of navigation and orientation equipment for agricultural machinery aimed to the implementation of autonomous moving and mission equipment control. Technics automatization is possible due to refitting of already existing samples with specialized attachments. According to this analysis, foreign agricultural machinery is far ahead of domestic manufacturers for the production of crew-unmanned facilities of mechanization for the agricultural sector, and the material intensity of the existing agricultural production in Russia is 3-4 times higher than that of foreign countries. The need for this kind of analysis is explained by the result of a comparison labor productivity: this index in Russia's agriculture is by 2.4 times lower than European one and 3.5 times lower than that of the USA. The Russian agriculture development retard can be eliminate through the use of modern achievements in the field of robotic systems for special purposes. The authors proved the possibility of double use of technologies because of similarity of schemes and structure of robotic systems for the solution of specialized tasks of both directions. The unmanned mobile energy vehicles can be used at sequential and parallel autonomous driving.

. Important decisions, such as participation in clinical trials, are likely to be made by those family members who are fluent in English and younger. Social class appears to be more important than ethnicity, and older South Asian people and those from working class backgrounds appear to be more mistrustful. Approachable patients (of the same gender, social class and fluent in English) tend to be 'cherry picked' to clinical trials. This practice was justified because of a lack of time and resources and inadequate support. South Asian patients might be systematically excluded from trials owing to the increased cost and time associated with their inclusion, particularly in relation to the language barrier. Under-representation might also be due to passive exclusion associated with cultural stereotypes. Other characteristics such as gender, age, educational level and social class can also affect trial inclusion. Effective strategies for South Asian recruitment to clinical trials include: using multi-recruitment strategies; defining the demographic and social profiles of the population to be included; using focus groups to identify any potential barriers; consulting representative community members to provide assistance in the study; ensuring eligibility criteria are set as wide as possible; developing educational and recruitment approaches to attract ethnic minority health professionals; ensuring health professionals are adequately trained in culturally and ethnically orientated service provision; determining the most effective mass media to use in study promotion and recruitment; and targeting inner-city, single-handed practices likely to have high ethnic minority populations. Future research should consider: responses when invited to participate; the role of methodological and organisational barriers to recruitment; the complexities of recruitment from a health professional perspective; developing culturally sensitive research methods; the magnitude of the problem of under

Using special additions to preparation of the moulding mixture for casting steel parts of drive wheel type

2015-06-01

The paper presents the possibility of using special additions to the execution of moulding mixtures for steel castings, drive wheel type. Critical analysis of moulding technology leads to the idea that most defects appear due to using improper moulding mixture. Using a improper moulding mixture leads to penetration of steel in moulding mixture, resulting in the formation of adherences, due to inadequate refractarity of the mould and core mixtures. Using only the unique mixture to the moulding leads to increasing consumption of new sand, respectively to the increase of price of piece. Acording to the dates registered in the industrial practice is necessary to use the special additions to obtain the moulding mixtures, carbonaceous materials respectively.

The South China Sea is poorly understood in terms of its marine biota, ecology and the human impacts upon it. What is known is most often contained in reports and workshops and conference documents that are not available to the wider scientific community. The South China Sea has an area of some 3.3 million km{sup 2} and depths range from the shallowest coastal fringe to 5377m in the Manila Trench. It is also studded with numerous islets, atolls and reefs many of which are just awash at low tide. It is largely confined within the Tropic of Cancer and, therefore, experiences a monsoonal climate being influenced by the Southwest Monsoon in summer and the Northeast Monsoon in winter. The South China Sea is a marginal sea and, therefore, largely surrounded by land. Countries that have a major influence on and claims to the sea include China, Malaysia, the Philippines and Vietnam, although Thailand, Indonesia and Taiwan have some too. The coastal fringes of the South China Sea are home to about 270 million people that have had some of the fastest developing and most vibrant economics on the globe. Consequently, anthropogenic impacts, such as over-exploitation of resources and pollution, are anticipated to be huge although, in reality, relatively little is known about them. The Indo-West Pacific biogeographic province, at the centre of which the South China Sea lies, is probably the world's most diverse shallow-water marine area. Of three major nearshore habitat types, i.e., coral reefs, mangroves and seagrasses, 45 mangrove species out of a global total of 51, most of the currently recognised 70 coral genera and 20 of 50 known seagrass species have been recorded from the South China Sea. The island groups of the South China Sea are all disputed and sovereignty is claimed over them by a number of countries. Conflicts have in recent decades arisen over them because of perceived national rights. It is perhaps because of this that so little research has been undertaken

We demonstrate Yokoyama gaugeon formalism for the Abelian one-form gauge (Maxwell) as well as for Abelian two-form gauge theory in the very special relativity (VSR) framework. In VSR scenario, the extended action due to introduction of gaugeon fields also possesses form invariance under quantum gauge transformations. It is observed that the gaugeon field together with gauge field naturally acquire mass, which is different from the conventional Higgs mechanism. The quantum gauge transformation implements a shift in gauge parameter. Further, we analyze the BRST symmetric gaugeon formalism in VSR which embeds only one subsidiary condition rather than two.

Emission Sectoral Contributions of Foreign Emissions to Particulate Matter Concentrations over South Korea

In this study, we investigated the contributions of major emission source categories located upwind of South Korea to Particulate Matter (PM) in South Korea. In general, air quality in South Korea is affected by anthropogenic air pollutants emitted from foreign countries including China. Some studies reported that foreign emissions contributed 50 % of annual surface PM total mass concentrations in the Seoul Metropolitan Area, South Korea in 2014. Previous studies examined PM contributions of foreign emissions from all sectors considering meteorological variations. However, little studies conducted to assess contributions of specific foreign source categories. Therefore, we attempted to estimate sectoral contributions of foreign emissions from China to South Korea PM using our air quality forecasting system. We used Model Inter-Comparison Study in Asia 2010 for foreign emissions and Clean Air Policy Support System 2010 emission inventories for domestic emissions. To quantify contributions of major emission sectors to South Korea PM, we applied the Community Multi-scale Air Quality system with brute force method by perturbing emissions from industrial, residential, fossil-fuel power plants, transportation, and agriculture sectors in China. We noted that industrial sector was pre-dominant over the region except during cold season for primary PMs when residential emissions drastically increase due to heating demand. This study will benefit ensemble air quality forecasting and refined control strategy design by providing quantitative assessment on seasonal contributions of foreign emissions from major source categories.

Challenges in Collating Spirometry Reference Data for South-Asian Children: An Observational Study.

Directory of Open Access Journals (Sweden)

Sooky Lum

Full Text Available Spirometry datasets from South-Asian children were collated from four centres in India and five within the UK. Records with transcription errors, missing values for height or spirometry, and implausible values were excluded(n = 110.Following exclusions, cross-sectional data were available from 8,124 children (56.3% male; 5-17 years. When compared with GLI-predicted values from White Europeans, forced expired volume in 1s (FEV1 and forced vital capacity (FVC in South-Asian children were on average 15% lower, ranging from 4-19% between centres. By contrast, proportional reductions in FEV1 and FVC within all but two datasets meant that the FEV1/FVC ratio remained independent of ethnicity. The 'GLI-Other' equation fitted data from North India reasonably well while 'GLI-Black' equations provided a better approximation for South-Asian data than the 'GLI-White' equation. However, marked discrepancies in the mean lung function z-scores between centres especially when examined according to socio-economic conditions precluded derivation of a single South-Asian GLI-adjustment.Until improved and more robust prediction equations can be derived, we recommend the use of 'GLI-Black' equations for interpreting most South-Asian data, although 'GLI-Other' may be more appropriate for North Indian data. Prospective data collection using standardised protocols to explore potential sources of variation due to socio-economic circumstances, secular changes in growth/predictors of lung function and ethnicities within the South-Asian classification are urgently required.

Evaluating options for sustainable energy mixes in South Korea using scenario analysis

Hong, Sanghyun; Bradshaw, Corey J.A.; Brook, Barry W.

2013-01-01

To mitigate greenhouse gas emissions, coal-fired electricity infrastructure needs to be replaced by low-carbon electricity generation options. Here we examine a range of possible alternative scenarios for sustainable electricity generation in South Korea, considering both physical and economic limits of current technologies. The results show that South Korea cannot achieve a 100% renewable energy mix and requires at least 55 GW of backup capacity. Given that constraint, we modelled seven scenarios: (i) the present condition, (ii) the First National Electricity Plan configuration, (iii) renewable energy (including 5 GW photovoltaic) with fuel cells or (iv) natural gas backup, (v) maximum renewable energy (including 75 GW photovoltaic) with natural gas, (vi) maximum nuclear power, and (vii) nuclear power with natural gas. We then quantify levelised cost of electricity, energy security, greenhouse gas emissions, fresh water consumption, heated water discharge, land transformation, air pollutant emissions, radioactive waste disposal, solid waste disposal and safety issues for each modelled mix. Our analysis shows that the maximum nuclear power scenario yields the fewest overall negative impacts, and the maximum renewable energy scenario with fuel cells would have the highest negative impacts. - Highlights: ► Due to physical limits of renewable sources, renewable energy cannot provide total electricity consumption in South Korea. ► A massive expansion of solar power will act to save only a small amount of backup fuel at greatly increased costs. ► A huge supply of natural gas capacity is essential, due to the absence of feasible large-scale energy storage. ► A pathway to maximize renewable energy causes more environmental and economic disadvantages than the status quo. ► Maximizing nuclear power is the most sustainable option for South Korea

The collision of rights and its impact on access to essential medicines: Challenges for South America

Full Text Available The collision between intellectual property rights and the right to health due to obligations assumed simultaneously –the WTO trips Agreement and the United Nations International Covenant on Economic, Social and Cultural Rights– by the twelve countries of South America, has had a profound impact regarding their populations access to essential medicines. The paper reports this situation in the region, while placing it in the context of the debate on trade and human rights, which has been particularly strong since the beginning of this century in the field of public health. The need for South American countries to strengthen intraregional cooperation as well as the promotion of South-South cooperation in access to essential medicines, taking into account the prevalence of pharmaceutical patents held by private laboratories in the northern hemisphere, is underlined. The advances made in this direction by the South American Health Council of Unasur, together with its actions as a regional bloc at the WTO meetings, are promising steps that must be complemented by the development of joint drug production capabilities.

Context: Sports specialization is intense training in 1 sport while excluding others. Sports specialization in early to middle childhood has become increasingly common. While most experts agree that some degree of sports specialization is necessary to achieve elite levels, there is some debate as to whether such intense practice time must begin during early childhood and to the exclusion of other sports to maximize potential for success. There is a concern that sports specialization before adolescence may be deleterious to a young athlete. Evidence Acquisition: PubMed and OVID were searched for English-language articles from 1990 to 2011 discussing sports specialization, expert athletes, or elite versus novice athletes, including original research articles, consensus opinions, and position statements. Results: For most sports, there is no evidence that intense training and specialization before puberty are necessary to achieve elite status. Risks of early sports specialization include higher rates of injury, increased psychological stress, and quitting sports at a young age. Sports specialization occurs along a continuum. Survey tools are being developed to identify where athletes fall along the spectrum of specialization. Conclusion: Some degree of sports specialization is necessary to develop elite-level skill development. However, for most sports, such intense training in a single sport to the exclusion of others should be delayed until late adolescence to optimize success while minimizing injury, psychological stress, and burnout.

Numerical assessment of factors affecting nonlinear internal waves in the South China Sea

Science.gov (United States)

Li, Qiang

2014-02-01

Nonlinear internal waves in the South China Sea exhibit diverse characteristics, which are associated with the complex conditions in Luzon Strait, such as the double ridge topography, the Earth’s rotation, variations in stratification and the background current induced by the Kuroshio. These effects are individually assessed using the MITgcm. The performance of the model is first validated through comparison with field observations. Because of in-phased ray interaction, the western ridge in Luzon Strait intensifies the semidiurnal internal tides generated from the eastern ridge, thus reinforcing the formation of nonlinear internal waves. However, the ray interaction for K1 forcing becomes anti-phased so that the K1 internal tide generation is reduced by the western ridge. Not only does the rotational dispersion suppress internal tide generation, it also inhibits nonlinear steepening and consequent internal solitary wave formation. As a joint effect, the double ridges and the rotational dispersion result in a paradoxical phenomenon: diurnal barotropic tidal forcing is dominant in Luzon Strait, but semidiurnal internal tides prevail in the deep basin of the South China Sea. The seasonal variation of the Kuroshio is consistent with the seasonal appearance of nonlinear internal waves in the South China Sea. The model results show that the westward inflow due to the Kuroshio intrusion reduces the amplitude of internal tides in the South China Sea, causing the weakening or absence of internal solitary waves. Winter stratification cannot account for the significant reduction of nonlinear internal waves, because the amplitude growth of internal tides due to increased thermocline tilting counteracts the reduced nonlinearity caused by thermocline deepening.

Full Text Available The objective of this study was to investigate the role of human capital in the competitive platform of South African industries and to determine the ability of their human capital to address the challenges of modern technology and globalisation. Attention is given to the competitive strengths and investment opportunities, including the quality and availability of human resources, labour cost, level of education and skills, vocational and industry related training facility, work ethics, productivity, workplace regulations, as well as efficiency of the civil service; including productivity and competitiveness indexes. The study found that the level of human capital in South African industries is much higher than the general perception and not the worst element of South Africa’s competitive platform. The findings also indicated challenges, like absentees due to AIDS and other factors, a shortage of artisans and proficiency towards modern technology and innovation, which limits competitiveness.

La Niña conditions during boreal winter sometimes brings excessive snowfall in Japan, especially on the East Sea/Sea of Japan coastal and mountain areas through intensified northwesterly cold winds caused by La-Niña related atmospheric teleconnection. Meanwhile, snowfall events also increase in the Pacific coast area of Japan during the El Niño state due to extratropical cyclones passing along the south coast of Japan (hereafter referred to as South-coast cyclone). In the present study, we investigated year-to-year snowfall/rainfall variations based on meteorological station data and cyclone tracks identified by using the Japanese 55-year Reanalysis. The result clearly indicates increase of the South-coast cyclone during El Niño-developing winters, which is consistent with excessive snow-fall in the northern part of the Pacific coast. Strong subtropical jet hampers cyclogenesis due to less vertical interaction through the trapping of upper-level eddies. During El Niño-developing winters, the subtropical jet is weakened over East Asia, indicating dynamic linkage to increased cyclone frequency. In addition to this, both the deepening of the upper-tropospheric trough over East Asia and anomalous low-tropospheric northwest anticyclones extending from the Philippines toward Japan are also consistent with the enhancement of cyclogenesis over the East China Sea as well as warm winter in Japan.

Performance of special wasteform lysimeters and waste migration at a humid site

McIntyre, P.F.

1986-01-01

The special wasteform lysimeter (SWL) program at the Savannah River Laboratory (SRL) near Aiken, South Carolina, is designed to measure leaching behavior and radionuclide migration under realistic burial conditions at a humid site. A similar program at an arid site is being conducted at Hanford near Richland, Washington. The wasteforms were placed in the lysimeters in March 1982 and represent typical low-level waste from two commercial reactors. An extensive report covering the initial three years of operation was issued in November 1985. This report updates the results of that report and includes significant observations made during the past year of operation. The Waste Migration Program at SRL included continued monitoring of 40 defense waste lysimeters, radionuclide uptake by pine trees, and measurement of total organic carbon in the groundwater of the burial ground

2010-01-01

Patients from the Indian subcontinent have a distinct cardiovascular risk profile with profound health consequences. South Asians tend to develop more severe coronary artery disease at a younger age, and may also suffer from earlier myocardial infarction and heart failure. The genesis of this risk is multi-factorial. One important culprit is increased insulin resistance, possibly due to recently identified genetic polymorphisms. Another possible explanation is subclinical inflammation and a prothrombotic environment, as evidenced by increased levels of homocysteine, plasminogen activator inhibitor-1, and fibrinogen. The lipid profile of South Asians may play a role, as this population is known to have elevated levels of lipoprotein (a), as well as lower levels of HDL. In addition, this HDL may be dysfunctional, as this population may have a higher prevalence of low levels of HDL2b, as well as an increased preponderance of smaller HDL. Current guidelines for primary and secondary prevention have not reflected our growing insight into the unique characteristics of the South Asian population, and may need to evolve to reflect our knowledge.

Globalisation and local power: influences on health matters in South Africa.

Science.gov (United States)

Gilbert, Tal; Gilbert, Leah

2004-03-01

This paper reviews some of the multiple influences on health issues in South Africa, placing them in the context of globalisation. By examining the complexity of factors, both domestic and global, which impact on these issues, it questions the extent to which global patterns in areas such as health policy, HIV/AIDS, health care pluralism, and neo-liberal macroeconomic policy have played out in South Africa. The identification of some of the multiple and complex forces in each case reveals a relatively consistent story of global pressures interacting with domestic realities, with some recognizably local results. There is no doubt that a full and nuanced understanding of health in South Africa requires an appreciation of developments in the global political economy, international organizations such as the WHO and World Bank, and forces which operate outside of institutions. In each case, however, the specific opportunities available to actors within the country, as well as the relative power of those actors, should be given their due consideration in analysing their potential impact on health matters.

The south west coast of Kanyakumari district in Tamil Nadu, India, is significantly affected by seawater intrusion and diffusion of pollutants into the aquifers due to unregulated beach placer mining and other anthropogenic activities. The present study investigates the vulnerability of the coastal aquifers using Geographic Information System (GIS)-based DRASTIC model. The seven DRASTIC parameters have been analyzed using the statistical equation of this model to demarcate the vulnerable zones for aquifer contamination. The vulnerability index map is prepared from the weighted spatial parameters, and an accounting of total index value ranged from 85 to 213. Based on the categorization of vulnerability classes, the high vulnerable zones are found near the beach placer mining areas between Manavalakurichi and Kodimanal coastal stretches. The aquifers associated with settlements and agricultural lands in the middle-eastern part have experienced high vulnerability due to contaminated water bodies. Similarly, the coastal areas of Thengapattinam and Manakudi estuary and around the South Tamaraikulam have also been falling under high vulnerability condition due to backwater and saltpan. In general, the nearshore region except the placer mining zone and the backwater has a moderately vulnerable condition, and the vulnerability index values range from 149 to180. Significantly, the northern and northeastern uplands and some parts of deposition zones in the middle-south coast have been identified as low to no vulnerable conditions. They are structurally controlled by various geological features such as charnockite, garnet biotite gneiss and granites, and sand dunes, respectively. The aquifer vulnerability assessment has been cross-verified by geochemical indicators such as total dissolved solids (TDS), Cl(-), HCO₃(-), and Cl(-)/HCO₃(-) ratio. The high ranges of TDS (1,842--3,736 mg/l) and Cl(-) (1,412--2,112 mg/l) values are well correlated with the observed high

The impact of improving suicide death classification in South Korea: a comparison with Japan and Hong Kong.

Full Text Available The suicide rate of South Korea has increased dramatically during the past decades, as opposed to steadily decreasing trends in Japan and Hong Kong. Although the recent increase of suicide in South Korea may be related to changing socioeconomic conditions and other contextual factors, it may also reflect, in part, a reduction of misidentified suicide cases due to improving classification of manner of death.We compared the annual proportional change of suicide, undetermined death, and accidental death from South Korea with those of Japan and Hong Kong from 1992 to 2011; a greater proportional change of the manner-of-death categories during the period is indicative of a relatively less stable registration and hence a greater potential for misclassification bias on reported suicide trends. Subgroup analyses stratifying the deaths by methods were also conducted. To estimate the impact, the age-standardized rates of these three death categories in each site were calculated.We found that, during the 20-year observation period, the proportional change of suicide, undetermined death, and accidental death in South Korea was significantly greater than Japan and Hong Kong. Similar observations were made in subgroup analyses. While death rates of the three manners in Japan and Hong Kong generally moved in a parallel fashion, the increase of suicide in South Korea occurred concomitantly with a significant reduction of its accidental death rate. 43% of the increase in suicides could be attributed to the decrease in accidental deaths, while 57% of the increase could be due to fundamental causes.Our data suggest that, during the mid-1990s and after, the increasing burden of suicide in South Korea initially was masked, in part, by misclassification. Thus, the later apparently rapid increase of suicides reflected steadily improving classification of manner of death, as well as a more fundamental increase in the suicide rate.

Schweiger, Bernd

2012-01-01

Due to the morphology of the small body and the special feature of athe growing organism children are notably radiation sensitive. It is an aggravating fact that due to missing adaptation of examination parameters the infantile bodies can be exposed to needless high radiation doses. This is especially the fact in case of computerized tomography that has reached increased importance during the last years. Therefore it is recommended to use primarily ultrasonography or MRT. X-ray examinations of children require specific adapted examination protocols targeted to optimized dose reduction. The author discusses the issues physical aspects, anatomic differences, tissue radiation sensitivity, life expectation and genetic risk, critical indication tracking in pediatrics, adaptation of examination parameters to body size and anatomy.

Endothelial damage due to air pollution

Livio Dei Cas

Full Text Available The first human deaths due to air pollution were recorded in the mid-20th century. There were 6,000 cases of illness recorded in Donora, Pennsylvania, in 1948 and 20,000 in London in 1952; 15 and 4,000 cases of death, respectively, were allegedly ascribed to air pollution. Since then, many countries have adopted standards of air quality in order to protect environmental and human health, although the quality of the air in some industrialized countries remains worrying. Emerging countries in the Far East and South America are also cause for concern because of the growth in the population, industrialization and transport. The WHO World Health Report 2002 estimated that air pollutants, particularly PM10, are associated with a mortality rate of 5% for cancer of the respiratory system, 2% for cardiovascular diseases and about 1% for respiratory tract infections. These estimates consider the mortality but not the morbidity rate, which would increase proportionally the number of cases of these pathologies, despite the difficulty in evaluation.

ACADEMIC DEPENDENCY ON WESTERN DISCIPLINARY KNOWLEDGE AND CAPTIVE MIND AMONG SOUTH ASIAN SOCIOLOGISTS: A CRITIQUE

Directory of Open Access Journals (Sweden)

Siri Gamage

2016-10-01

Full Text Available This paper examines how academic dependency of South Asia on the West has resulted in what has been termed ‘captive mind’, and its impact on the knowledge production process of South Asia. To this end, it observes that the relationship between Western centres of Social Science teaching and learning vs. those of the global South, in particular Asia, is an unequal one that stems from the colonial past, leading to the treatment of Western methods and types of knowledge production as superior and therefore worthy of imitation. The application of American and European methods of studying the Social Sciences to Asian settings without due adaptation, it argues, has rendered South Asian Sociology largely incapable of generating original knowledge to contribute to the growth of an emancipatory sociological imagination that will function for the benefit of the populace. Therefore it appeals to South Asian Sociologists – and other Social Scientists – to abandon the practice of studying regional social institutions as if these are exotic phenomena, practices, norms and ritual, and evolve their disciplinary framework in more critical, creative, and relevant ways.

Supersymmetric black holes in AdS4 from very special geometry

Gnecchi, Alessandra; Halmagyi, Nick

2014-01-01

Supersymmetric black holes in AdS spacetime are inherently interesting for the AdS/CFT correspondence. Within a four dimensional gauged supergravity theory coupled to vector multiplets, the only analytic solutions for regular, supersymmetric, static black holes in AdS 4 are those in the STU-model due to Cacciatori and Klemm. We study a class of U(1)-gauged supergravity theories coupled to vector multiplets which have a cubic prepotential, the scalar manifold is then a very special Kähler manifold. When the resulting very special Kähler manifold is a homogeneous space, we find analytic solutions for static, supersymmetric AdS 4 black holes with vanishing axions. The horizon geometries of our solutions are constant curvature Riemann surfaces of arbitrary genus

Non-communicable diseases in South Asia: contemporary perspectives.

2014-09-01

Non-communicable diseases (NCDs) such as metabolic, cardiovascular, cancers, injuries and mental health disorders are increasingly contributing to the disease burden in South Asia, in light of demographic and epidemiologic transitions in the region. Home to one-quarter of the world's population, the region is also an important priority area for meeting global health targets. In this review, we describe the current burden of and trends in four common NCDs (cardiovascular disease, diabetes, cancer and chronic obstructive pulmonary disease) in South Asia. The 2010 Global Burden of Disease Study supplemented with the peer-reviewed literature and reports by international agencies and national governments. The burden of NCDs in South Asia is rising at a rate that exceeds global increases in these conditions. Shifts in leading risk factors-particularly dietary habits, tobacco use and high blood pressure-are thought to underlie the mounting burden of death and disability due to NCDs. Improvements in life expectancy, increasing socioeconomic development and urbanization in South Asia are expected to lead to further escalation of NCDs. Although NCD burdens are currently largest among affluent groups in South Asia, many adverse risk factors are concentrated among the poor, portending a future increase in disease burden among lower income individuals. There continues to be a notable lack of national surveillance data to document the distribution and trends in NCDs in the region. Similarly, economic studies and policy initiatives addressing NCD burdens are still in their infancy. Opportunities for innovative structural and behavioral interventions that promote maintenance of healthy lifestyles-such as moderate caloric intake, adequate physical activity and avoidance of tobacco-in the context of socioeconomic development are abundant. Testing of health care infrastructure and systems that best provide low-cost and effective detection and treatment of NCDs is a priority for

The 'Ecosystem History of Biscayne Bay and the southeast Coast' project of the U.S. Geological Survey is part of a multi-disciplinary effort that includes Florida Bay and the Everglades to provide paleoecologic reconstructions for the south Florida region. Reconstructions of past salinity, nutrients, substrate, and water quality are needed to determine ecosystem variability due to both natural and human-induced causes. Our understanding of the relations between the south Florida ecosystem and introduced forces will allow managers to make informed decisions regarding the south Florida ecosystem restoration and monitoring. The record of past ecosystem conditions can be found in shallow sediment cores. This U.S. Geological Survey Open-File Report describes six shallow sediment cores collected from Biscayne Bay. The cores described herein are being processed for a variety of analytical procedures, and this provides the descriptive framework for future analyses of the included cores. This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code.

The recent increase in surface particulate matter (PM) concentrations in South Korea is intriguing due to its disagreement with current intensive emission reduction efforts. The long-term trend of surface PM concentrations in South Korea declined in the 2000s, but since 2012 its concentrations have tended to increase, resulting in frequent severe haze events in the region. This study demonstrates that the interannual variation of surface PM concentrations in South Korea is not only affected by changes in local or regional emission sources, but also closely linked with the interannual variations in regional ventilation. Using EPA Community Multiscale Air Quality modeling system, a 12-year (2004-2015) regional air quality simulation was conducted to assess the impact of the meteorological conditions under constant anthropogenic emissions. In addition, NOAA HYSPLIT dispersion model was utilized to estimate the strength of regional ventilation that dissipates local pollutions. Simulated PM concentrations show a strong negative correlation (i.e. R=-0.86) with regional wind speed, implying that reduced regional ventilation is likely associated with more stagnant conditions that cause severe pollutant episodes in South Korea. We conclude that the current PM concentration trend in South Korea is a combination of long-term decline by emission control efforts and short-term fluctuations in regional wind speed interannual variability. When the meteorology-driven variations are removed, PM concentrations in South Korea have declined continuously even after 2012, with -1.45±0.12, -1.41±0.16, and -1.09±0.16 mg/m3 per year in Seoul, the Seoul Metropolitan Area, and South Korea, respectively.

Disaster Vulnerability in South Korea under a Gender Perspective

Chung, Gunhui

2017-04-01

The most affected natural disaster has been flooding in South Korea, however, many unexpected natural disasters cause by snow or drought have become severe due to the climate change. Therefore it is very important to analyze disaster vulnerability under the unexpected climate condition. When the natural disaster happens, in many cases, female was more damaged than male because of the cultural and physical limitations. Disaster is never gender neutral. For example, four times as many female as male died in Indonesia tsunami. Therefore, it is very important to consider gender sensitivity in the disaster vulnerability to mitigate effects on the female. In this study, the current disaster management guideline in South Korea is investigated in the gender perspective and compared to the other countries. As a result, gender analysis in the disaster preparedness and response is not implemented in South Korea. Thus, the gender balanced disaster management guideline is newly proposed. Also, the disaster vulnerability considering gendered factors are evaluated and analyzed in the urban area.

South African President F. W. de Klerk made headlines on March 24 when he admitted to a joint session of parliament that South Africa had once had a supply of nuclear weapons; six of seven planned devices had been completed. South African spokesmen had previously said that Pretoria was capable of building weapons, but they had remained deliberately vague about whether or not any had been built. According to de Klerk, the weapons were dismantled before South Africa signed the Nuclear Non-Proliferation Treaty on July 10, 1991. De Klerk's revelation came in response to charges by the African National Congress and U.S. government officials that South Africa had possibly hidden atomic bomb components and manufacturing plants and that it had been evasive about its stockpile of weapon-grade uranium. A more complete discussion of de Klerk's disclosure and events leading to the admission are explored in this article

2017-11-01

The article tackles the issues of designing seasonal water and power supply systems for small recreational facilities in the south of Russia based on intelligent decision support systems. The paper proposes modular prefabricated shell water and power supply works (MPSW&PW) along with energy-efficient standalone water-treatment plants as the principal facilities compliant with the environmental and infrastructural requirements applied to specially protected areas and ensuring the least possible damage to the environment due to a maximum possible use of local construction materials characterized by impressive safety margins in highly seismic environments. The task of designing water and power supply systems requires the consideration of issues pertaining to the development of an intelligent GIS-based system for the selection of water intake sites that facilitate automation of data-processing systems using a priori scanning methods with a variable step and random directions. The paper duly addresses such issues and develops parameterized optimization algorithms for MPSW&PW shell facilities. It equally provides the substantiation of water-treatment plants intelligent design based on energy recovery reverse osmosis and nanofiltration plants that enhance the energy efficiency of such plants serving as the optimum solution for the decentralized water supply of small recreational facilities from renewable energy sources.

Full Text Available The detection, investigation and prosecution of crimes against the environment has its specificity compared to other forms of crime, because of the nature of these crimes, the manner of execution (modus operandi and the characteristics of their perpetrators. Although there is no objective need for modification of the rules of criminal procedure with regard to these offenses, there is an obvious need for a specialized body of the procedure (prosecutors, judges and authorized officers of the internal affairs. This is due the fact that only specific additional, specialized knowledge about the environmental issues, which is usually multidisciplinary, can provide high-quality, professional and competent research and detection of crimes against the environment. In this paper, the authors deal with the problems of specialization of judicial and other authorities in connection with criminal proceedings for offenses against the environment, of reasonableness and necessity, given the current situation in domestic practice, as well as some comparative solutions and experiences.

Nutrition transition in South Asia: the emergence of non-communicable chronic diseases [version 2; referees: 2 approved

Full Text Available Overview: South Asian countries have experienced a remarkable economic growth during last two decades along with subsequent transformation in social, economic and food systems. Rising disposable income levels continue to drive the nutrition transition characterized by a shift from a traditional high-carbohydrate, low-fat diets towards diets with a lower carbohydrate and higher proportion of saturated fat, sugar and salt. Steered by various transitions in demographic, economic and nutritional terms, South Asian population are experiencing a rapidly changing disease profile. While the healthcare systems have long been striving to disentangle from the vicious cycle of poverty and undernutrition, South Asian countries are now confronted with an emerging epidemic of obesity and a constellation of other non-communicable diseases (NCDs. This dual burden is bringing about a serious health and economic conundrum and is generating enormous pressure on the already overstretched healthcare system of South Asian countries.   Objectives: The Nutrition transition has been a very popular topic in the field of human nutrition during last few decades and many countries and broad geographic regions have been studied. However there is no review on this topic in the context of South Asia  as yet. The main purpose of this review is to highlight the factors accounting for the onset of nutrition transition and its subsequent impact on epidemiological transition in five major South Asian countries including Bangladesh, India, Nepal, Pakistan and Sri Lanka. Special emphasis was given on India and Bangladesh as they together account for 94% of the regional population and about half world’s malnourished population. Methods: This study is literature based. Main data sources were published research articles obtained through an electronic medical databases search.

A 10-year (1998-2008) retrospective study was carried out to investigate the prevalence and long-term trend of hydatid disease in slaughtered herbivores in the large complex abattoir of Ahwaz (the capital of Khuzestan province, south-western Iran). A total of 3,583,417 animals including 2,815,982 sheep, 427,790 goats and 339,645 cattle were inspected macroscopically for hydatid cysts in the 10-year period, and overall 155,555 (4.24%) livers and 228,172 (6.37%) lungs were condemned. Cystic echinococcosis (CE) was responsible for 36.08% and 48.04% of total liver and lung condemnations, respectively. The prevalence of pulmonary hydatid disease in sheep, goats and cattle was 2.22, 5.43 and 6.99%, respectively; on the other hand, the prevalence of hepatic hydatid disease for those animals was 1.26, 2.57 and 2.80%, respectively. Data showed an overall downward long-term trend for CE in all livestock slaughtered during the study period (P trend was still observed. The total annual economic loss incurred due to hydatidosis in all ruminants slaughtered at Ahwaz municipal abattoir was estimated to be US$459,659.6, based on the market prices in the year 2008. This number corresponds to a loss of US$300,620.4 for cattle, US$123,490.0 for sheep and US$35,549.2 for goats. The current results provide baseline data for the future monitoring of this potentially important disease in the region, and also suggest that a thorough investigation leading to a disease control strategy is required to reduce the economic and public health consequences of CE.

Continental rifting in the South China Sea culminated in seafloor spreading at ∼ 30Ma (Late Oligocene). The basin and associated margins form a classic example of break-up in a relatively juvenile arc crust environment. In this study, we documented the timing, distribution and amount of extension in the crust and mantle lithosphere on the South China Margin during this process. Applying a one-dimensional backstripping modeling technique to drilling data from the Pearl River Mouth Basin (PRMB) and Beibu Gulf Basin, we calculated subsidence rates of the wells and examined the timing and amount of extension. Our results show that extension of the crust exceeded that in the mantle lithosphere under the South China Shelf, but that the two varied in phase, suggesting depth-dependent extension rather than a lithospheric-scale detachment. Estimates of total crustal extension derived in this way are similar to those measured by seismic refraction, indicating that isostatic compensation is close to being local. Extension in the Beibu Gulf appears to be more uniform with depth, a difference that we attribute to the different style of strain accommodation during continental break-up compared to intra-continental rifting. Extension in PRMB and South China slope continues for ∼ 5m.y. after the onset of seafloor spreading due to the weakness of the continental lithosphere. The timing of major extension is broadly mid-late Eocene to late Oligocene (∼ 45-25Ma), but is impossible to correlate in detail with poorly dated strike-slip deformation in the Red River Fault Zone.

Hand-arm vibration syndrome (HAVS) is associated with the use of hand-held vibrating tools. Affected workers may experience symptoms of tingling, numbness, loss of grip strength and pain. Loss of dexterity may impair everyday activities, and potentially increase the risk of occupational accidents. Although high vibration levels (up to 31 m/s(2)) have been measured in association with rock drills, HAVS has not been scientifically evaluated in the South African mining industry. The aim of this study was to determine the prevalence and severity of HAVS in South African gold miners, and to identify the tools responsible. A cross-sectional study was conducted in a single South African gold-mine. Participants were randomly selected from mineworkers returning from annual leave, comprising 156 subjects with occupational exposure to vibration, and 140 workers with no exposure. Miners who consented to participate underwent a clinical HAVS assessment following the UK Health and Safety Laboratory protocol. The prevalence of HAVS in vibration-exposed gold miners was 15%, with a mean latent period of 5.6 years. Among the non-exposed comparison group, 5% had signs and symptoms indistinguishable from HAVS. This difference was statistically significant (P < 0.05). All the cases of HAVS gave a history of exposure to rock drills. The study has diagnosed the first cases of HAVS in the South African mining industry. The prevalence of HAVS was lower than expected, and possible explanations for this may include a survivor population, and lack of vascular symptom reporting due to warm-ambient temperatures.

The purpose of this case study was to relate part of the journey to appropriate education for two young children with physical disabilities in a low socio-economic peri-urban informal settlement - or 'township' - in South Africa. The part of the on-going journey described here spanned four-and-a-half years and included the two children, their families, their teachers, their community and a small team of rehabilitation professionals working for a non-profit organisation in the area. The rehabilitation professionals' goals were to provide support for the children, their families, their current special care centre and the school(s) they would attend in the future. The steps from the special care centre, to a mainstream early childhood development (ECD) centre for both of them, and then on to (a) a school for learners with special educational needs (LSEN) for one child and (b) a mainstream primary school for the other, are described. Challenges encountered on the way included parental fears, community attitudes and physical accessibility. Practical outcomes included different placements for the two children with implications and recommendations for prioritised parent involvement, individual approaches, interdisciplinary and community-based collaborations. Recommendations are given for clinical contexts, curricula and policy matters; for research and for scaling up such a programme through community workers.

Full Text Available Due to the complexity of the educational sector, the work is topical, even though over time there have been many concerns regarding its education and development and the correlation between the level of educational development and the level of economic development. The aim of the paper is to analyze the educational development at the level of the South-West Oltenia region over the period 2010-2015, thus using the statistical series for the mentioned timeframe we analyzed the evolution of the number of educational units in the South-West Oltenia region And the evolution of the school population in the South-West Oltenia region. Thus, the objective of the paper is enshrined in the overall objective of Romania, namely to reduce the economic and social development disparities between Romania and other EU Member States. The results of the analysis carried out by the two indicators, the number of educational units in the South-West Oltenia region and the number of the school population at the level of the South-West Oltenia region indicate that the number of educational units in the period 2010-2015 decreased by 4.28% And the number of the school population by 14.67%.

South African nuclear liability laws - recent changes and challenges for insurers

Da Silva, C.

2004-01-01

In the past South African Regulators did not stipulate the levels of insurance required by nuclear operators but required only that they carry adequate security. Over the last few years the South African legislators have given serious consideration to the Vienna Convention on Civil Liability for Nuclear Damage and the Paris Convention on Third Party Liability in the Field of Nuclear Energy, but decided against being signatories to such conventions. Instead, the conventions were used as a guideline as to specific requirements for local operators. Regulations have been drafted setting out specific limits of cover dependant on the type of licence held by local operators. Due to the fact that local liabilities will arise in local currencies the required limits of Insurance were converted from equivalent foreign amounts into Rands. Due to some extreme currency fluctuations this has resulted in the setting of very high Rand limits, placing both the operators and insurers in an uncertain and very difficult position with regards to accumulation adequate capacity. This paper aims at explaining the revisions that are being considered which if implemented will address insurers and operators concerns regarding available capacity the impossibility of compliance with current limits.(author)

Full Text Available In the present article author explores the history and legal framework for the creation and operation of international commercial arbitration in South Africa. Author notes that South Africa is the most economically developed country in Africa, it is among dozens of major international organizations. From the point of view of the development of the system of law, legal proceedings and arbitration, South Africa is an attractive state for study. Author emphasizes that the South African Republic throughout its existence has been influenced by two legal families: Anglo-Saxon and Romano-Germanic. Therefore, it is important to note that South Africa refers to a mixed system of law. To date, South Africa has two international commercial arbitration: the Arbitration Foundation of South Africa and the Association of Arbitrators. In the conclusion author points out that the development and establishment of the centers of the arbitration fund continues: new centers are being established, and the system of procedures for dealing with cases in already established centers is being improved.

Towards robust subsidence-based soil carbon emission factors for peat soils in south-east Asia, with special reference to oil palm plantations

Full Text Available Oil palm and Acacia pulpwood plantations are being established at a rapid rate on drained peatland in south-east Asia. Accurate measurements of associated carbon losses are still scarce, however, due mainly to difficulties of excluding autotrophic carbon fluxes from chamber-based flux measurements and uncertainties about the extent of waterborne losses. Here, we demonstrate a simple approach to determining total net carbon loss from subsidence records that is applicable to steady state conditions under continuous land use. We studied oil palm and Acacia plantations that had been drained for 5–19 years. Very similar subsidence rates and dry bulk density profiles were obtained, irrespective of crop type or age of the plantation, indicating that the peat profiles were in a steady state. These are conditions that allow for the deduction of net carbon loss by multiplying the rate of subsidence by the carbon density of the peat below the water table. With an average subsidence rate of 4.2 cm y-1 and a carbon density of 0.043 g cm-3, we arrive at a net carbon loss of ~18 t ha-1 y-1 (~66 t CO2-eq ha-1 y-1 for typical oil palm and Acacia plantations more than five years after drainage, without large differences between the plantation types. The proposed method enables calculation of regional or project-specific carbon loss rates to feed into mitigation schemes of the UN Framework Convention on Climate Change.

Seven human-specific Alu markers were studied in 574 unrelated individuals from 10 endogamous groups and 2 hill tribes of Tamil Nadu and Kerala states. DNA was isolated, amplified by PCR-SSP, and subjected to agarose gel electrophoresis, and genotypes were assigned for various Alu loci. Average heterozygosity among caste populations was in the range of 0.292-0.468. Among tribes, the average heterozygosity was higher for Paliyan (0.3759) than for Kani (0.2915). Frequency differences were prominent in all loci studied except Alu CD4. For Alu CD4, the frequency was 0.0363 in Yadavas, a traditional pastoral and herd maintaining population, and 0.2439 in Narikuravars, a nomadic gypsy population. The overall genetic difference (Gst) of 12 populations (castes and tribes) studied was 3.6%, which corresponds to the Gst values of 3.6% recorded earlier for Western Asian populations. Thus, our study confirms the genetic similarities between West Asian populations and South Indian castes and tribes and supported the large scale coastal migrations from Africa into India through West Asia. However, the average genetic difference (Gst) of Kani and Paliyan tribes with other South Indian tribes studied earlier was 8.3%. The average Gst of combined South and North Indian Tribes (CSNIT) was 9.5%. Neighbor joining tree constructed showed close proximity of Kani and Paliyan tribal groups to the other two South Indian tribes, Toda and Irula of Nilgiri hills studied earlier. Further, the analysis revealed the affinities among populations and confirmed the presence of North and South India specific lineages. Our findings have documented the highly diverse (micro differentiated) nature of South Indian tribes, predominantly due to isolation, than the endogamous population groups of South India. Thus, our study firmly established the genetic relationship of South Indian castes and tribes and supported the proposed large scale ancestral migrations from Africa, particularly into South India

Full Text Available The Gunungsewu area is a karst terrain with water scarcity, located in the Yogyakarta Special Province, adjacent to the open sea of Indian Ocean in the South. Shorelines of the Gunungsewu southern parts show fractal geometry phenomenon, and there can be found some groundwater outlets discharging to the Indian Ocean. One of the coastal outlets exists at the Baron Beach.The amount of water discharge from this spring reaches 20,000 l/sec in wet season, and approximately 9000 in dry season. In order to find other potential coastal springs, shoreline of the south coast is divided into some segments. By applying fractal analysis utilizing air photo of 1 : 30,000 scale, the fractal dimension of every shore line segment is determined, and then the fractal dimension value is correlated to the existence of spring in the segment being analyzed. The results inform us that shoreline segments having fractal dimension (D > 1.300 are potential for the occurrence of coastal springs.

Full text : Mud diapirism plays a special role in the geology and petroleum system of the south Caspian basin. Hundreads of mud intrusions penetrate the thick Plio-Pleistocene section. This article talks in detail about aspects of the influence of mud diapirs and their related with mud volcanoes on the generation and trapping of hydrocarbons. Some of these aspects are : 1) The influence on the sedimentation; 2) Structural impact; 3) Stress and strain in the surrounded formations; 4) Thermal effect; 5) Pressure effect. All these aspects of the diapiric and mud-volcanic activity should be kept in mind during the volumetric calculations and play evaluation.

Child Grooming and Sexual Exploitation: Are South Asian Men the UK Media’s New Folk Devils?

Full Text Available In May 2012, nine men from the Rochdale area of Manchester were found guilty of sexually exploiting a number of underage girls. Media reporting on the trial focused on the fact that eight of the men were of Pakistani descent, while all the girls were white. Framing similar cases in Preston, Rotherham, Derby, Shropshire, Oxford, Telford and Middlesbrough as ethnically motivated, the media incited moral panic over South Asian grooming gangs preying on white girls. While these cases shed light on the broader problem of sexual exploitation in Britain, they also reveal continuing misconceptions that stereotype South Asian men as ‘natural’ perpetrators of these crimes due to culturally-specific notions of hegemonic masculinity. Examining newspaper coverage from 2012 to 2013, this article discusses the discourse of the British media’s portrayal of South Asian men as perpetrators of sexual violence against white victims, inadvertently construing ‘South Asian men’ as ‘folk devils’.
