Full Text Available It is only appropriate to begin with his face. The intense, rainbow-colored Mandela portrait that opens this issue is the work of a young Indonesian digital artist, Ihsanulhakim, who captures a serious, reflective and aged version of the South African leader. The writing on the top left of the image is a quote from Mandela’s famous reflection on death translated into Indonesian: “Death is something inevitable. When a man has done what he considers to be his duty to his people and his country, he can rest in peace”.[1] [1] RIP Nelson Mandela © Muhammad Ihsanulhakim. I wish to thank the artist for generously allowing Altre Modernità to reproduce his work.

A life of refusal. Winnie Madikizela-Mandela and violence in South Africa

Full Text Available Winnie Madikizela-Mandela is an iconic woman in South African resistance politics. Not only the wife of Nelson Mandela, she was also a member of the ANC’s armed wing and supported the use of political violence. In the mid-1980s, she was implicated in the kidnapping and murder of young boys in Soweto. At the Truth and Reconciliation Commission in 1997, Madikizela-Mandela denied all allegations. Her testimony highlighted a key question: can women’s political roles be explored outside of the framework of political maternalism? The article uses fragments of interviews, and a recent essay by Madikizela-Mandela in which she presents a narrative account of the impact of imprisonment and political struggle on her life, as archival sources to explore how she made sense of her political actions. The article argues that although the maternalist paradigm is most frequently used to analyse the biography of Madikizela-Mandela, she herself foregrounds her identities as soldier.

Perceptions of patient-centred care at public hospitals in Nelson Mandela Bay

Full Text Available In South Africa, the quality of health care is directly related to the concept of patient-centred care and the enactment of the Batho Pele Principles and the Patients' Rights Charter. Reports in the media indicate that public hospitals in the Eastern Cape Province are on the brink of collapse, with many patients being treated in condemned hospitals which lacked piped water, electricity and essential medical equipment. Receiving quality care, and principally patient-centred care, in the face of such challenges is unlikely and consequently leads to the following question: “Are patients receiving patient-centred care in public hospitals?” A qualitative, explorative, descriptive and contextual study was conducted to explore and describe the perceptions of professional nurses regarding patient-centred care in public hospitals in Nelson Mandela Bay. Semi-structured interviews were conducted with a total of 40 purposively selected professional nurses working in public hospitals in Nelson Mandela Bay, Eastern Cape Province. Interviews were analysed according to the method described by Tesch in Creswell (2009:192. Professional nurses perceive patient-centred care as an awareness of the importance of the patient's culture, involving the patient's family, incorporating values of love and respect, optimal communication in all facets of patient care and accountability to the patient. Factors which enable patient-centred care were a positive work environment for staff, nursing manager's demonstrating exemplary professional leadership, continuous in service education for staff and collaborative teamwork within the interdisciplinary team. Barriers to patient-centred care were a lack of adequate resources, increased administrative work due to fear of litigation and unprofessional behaviour of nursing staff.

The Weathered Corrugations of His Face: A Performative Reflection on Nelson Mandela, Self, and the Call for Racial (UnBecoming

Directory of Open Access Journals (Sweden)

Paul Badenhorst

2015-03-01

Full Text Available On the occasion of the first anniversary of the death of Nelson Rolihlahla MANDELA, this self-exploratory narrative study utilizes a Butlerian performative theoretical framework to both uncover discursively regulated social practices as generative of raced identity ensconced in belonging, and the undoing of such identity through the redeployment of social practices predicated instead on a Weltanschauung of becoming. While the accountable subject of autoethnographic work is concomitantly problematized, fluid subjectivity is itself demonstrated as crucial to historical accountability. A resultant appeal for white South Africans to actively begin the work of defamiliarizing themselves with the sanitized dominant popular culture representation of the peace icon, this research ultimately calls for new existential reflection upon the face of Nelson MANDELA so as to begin uncovering its deeper historical significance, contemporary relevance, and the future ethical imperative it demands of those who come from a liminal position of, as J.M. COETZEE once wrote, "no longer European, not yet African" (1988, p.11. In short, it is argued that white South Africans need to move from a condition of belonging predicated on raced identity to one of transracial—and even interracial—African becoming.

Rene van Wyk

2014-11-01

Full Text Available This qualitative documentary analysis examines Nelson Mandela�s defence statement at the Rivonia Trial, Pretoria Supreme Court, on 20 April 1964. The defence document is analysed through the psychological capital lens, depicting themes that support the constructs of hope, efficacy, resilience and optimism. Psychological capital characteristics played a major role in the initial non-violent policies of negotiation. The inevitable establishment of Umkhonto we Sizwe followed, as a result of the increased restrictions and unwillingness of government to negotiate and collaborate. Mandela showed a determined spirit to unite the country. The discussion gives insight into Mandela�s authentic psychological capital leadership under difficult political and personal circumstances. Some implications are indicated in adopting Mandela�s psychological characteristics for personal reform.

Full Text Available Mandela’s victory in the 1994 elections in South Africa is a reference point for South African history and represented the transition from apartheid to multiracial democracy. Since then Nelson Mandela (1994-1999, Thabo Mbeki (1999-2008 and Jacob Zuma (2009 - current, occupied the post of president of the country and led, each in its own way, the new direction of the country. During the nearly twenty years of multiracial democracy, one in particular cartoonist, Jonathan Shapiro, popularly known by the pseudonym Zapiro, portrayed the everyday life of this story. In this sense, the objective of this research is to analyze how Zapiro portrayed the political and social aspects, as well as the psychological characteristics of each of the three postapartheid presidents and which social representations are formed from their cartoon production. The choice of Zapiro explained by openly declared his opposition to apartheid and also for being the best known outside South African cartoonist. We elected to cartoon as an object of study because it is an iconographic object constituted by communicative humor, which adds to its constitution arguments transgression of the established order, enabling an analysis of South African history through a critical bias. As methods for the development of the work, we decided to gather historical research, the literature search and analysis of cartooon speech. Among the theoretical frameworks stand out Magnoli (1998, 2009, Jonge (1991 and Carlin (2009 in the South African question; reflections about social representations, we resort to Moscovici (2011 and Jodelet (1993, in the field the cartoon and humor, the references are Miani (2005; 2012, Romualdo (2000 and Eco (1989. With the completion of the analysis, we observed that Zapiro acts in different ways in the construction of the representation of each of the presidents in question and that the cartoonist presents Mandela as a competent leader marked by heroism and

Obstetric haemorrhage is the leading direct cause of maternal mortality in South Africa. To determine the incidence, indications, associations and maternal outcomes of emergency peripartum hysterectomies. A descriptive and retrospective analysis of patients who had peripartum hysterectomy between 1(st) February 2007 and 31(st) January 2009 in Nelson Mandela Academic Hospital at Mthatha city. The incidence of 0.95% of peripartum hysterectomies (n=63 or 9.5/1000 births) increased with the increasing maternal age from 0.121% at age of less than 20 years to 0.5% at age more or equal to 30 years. Similarly the incidence increased with parity from 0.332% for Primiparity to 0.468% at parity of four or more. The indications for the operation were uterine atony 19/63 (30.2%), secondary haemorrhage/puerperal sepsis 17/63 (27%) and ruptured uterus 16/63 (23.4%). The main intra operative complication was haemorrhage 13/63 (20.6%). Repeat laparotomy was done in 10/63 (15%) of patients due to haemorrhage. Admission to intensive care unit was 25/63 (39.7%). The case specific mortality rate was of 19 % (n=12). The main causes of death were hypovolaemic shock and septicemia. The incidence of peripartum hysterectomies was high and was associated with ruptured uterus and puerperal sepsis which are preventable.

Diabetes mellitus is a growing problem in South Africa and of concern to traditional African health practitioners in the Nelson Mandela Metropole, because they experience a high incidence of diabetic cases in their practices. A collaborative research project with these practitioners focused on the screening of Bulbine frutescens, Ornithogalum longibracteatum, Ruta graveolens, Tarchonanthus camphoratus and Tulbaghia violacea for antidiabetic and cytotoxic potential. In vitro glucose utilisation assays with Chang liver cells and C2C12 muscle cells, and growth inhibition assays with Chang liver cells were conducted. The aqueous extracts of Bulbine frutescens (143.5%), Ornithogalum longibracteatum (131.9%) and Tarchonanthus camphoratus (131.5%) showed significant increased glucose utilisation activity in Chang liver cells. The ethanol extracts of Ruta graveolens (136.9%) and Tulbaghia violacea (140.5%) produced the highest increase in glucose utilisation in C2C12 muscle cells. The ethanol extract of Bulbine frutescens produced the most pronounced growth inhibition (33.3%) on Chang liver cells. These findings highlight the potential for the use of traditional remedies in the future for the management of diabetes and it is recommended that combinations of these plants be tested in future.

The rate of caesarean section deliveries has increased globally and mothers are faced with challenges of postoperative recovery and caring thereof. Midwives have a duty to assist these mothers to self-care. The objective was to explore and describe experiences of post-caesarean section delivered mothers of midwifery care at a public hospital in Nelson Mandela Bay. A qualitative, descriptive and explorative research design was used in the study. Data were collected from 11 purposively criterion-selected mothers who had a caesarean section delivery. One-on-one semi-structured interviews were conducted in the post-natal wards. Research ethics, namely autonomy, beneficence, justice and informed consent, were adopted in the study. All participants were informed of their right to withdraw from the study at any stage without penalties. Interviews were analysed using Tesch's method of data analysis. Three main themes were identified as experiences of: diverse pain, physical limitation and frustration and health care services as different. Experiences of mothers following a caesarean section delivery with midwifery services at a public hospital in Nelson Mandela Bay were explored and described as diverse. A need for adequate pain management as well as assistance and breastfeeding support to mothers following caesarean delivery was identified as crucial to promote a good mother-to-child relationship.

2016-12-01

The HIV prevalence in South Africa among students at higher education institutions (HEIs) in 2008 was reported to be 3.4%, with the highest HIV prevalence found in the Eastern Cape Province. Students at these facilities are also increasingly affected by socio-economic constraints that may impact on food security. Little is known about the impact of food insecurity on HIV-infected students in HEIs in South Africa. The purpose of this paper is to describe food insecurity and the nutritional status among HIV-infected students on the Nelson Mandela Metropolitan University campuses in South Africa, as well as current initiatives to strengthen the safety nets for food-insecure students. This descriptive, cross-sectional survey was conducted among a convenience sample of known HIV-infected, registered students (n = 63), older than 18 years of age and managed as part of the Campus Health Service antiretroviral therapy (ART) programme. Ethical approval for the study was obtained from the Research Ethics Committee (NMMU) and participants were included in the sample after providing written, informed consent. Findings indicate that food insecurity was common with more than 60% of the sample reporting food insecurity at the household level during the previous month. Of the sample, 51% were classified as being either overweight or obese. Although food insecurity did not contribute to weight loss in our sample, food-insecure students were more likely to consume inadequate amounts of vitamins and minerals, especially antioxidants that are important in supporting the immune system. Food insecurity has been identified as affecting the majority of HIV-infected students in this study, especially regarding their difficulty in accessing nutritious foods. As overweight and obesity also seem to threaten the health and future well-being of the students, appropriate management of the overweight individuals and those with obesity should be instituted in order to prevent the development

Power system reliability problems are very difficult to solve because the power systems are complex and geographically widely distributed and influenced by numerous unexpected events. It is therefore imperative to employ the most efficient optimization methods in solving the problems relating to reliability of the power system. This paper presents a reliability analysis and study of the power interruptions resulting from severe power outages in the Nelson Mandela Bay Municipality (NMBM), South Africa and includes an overview of the important factors influencing reliability, and methods to improve the reliability. The Blue Horizon Bay 22 kV overhead line, supplying a 6.6 kV residential sector has been selected. It has been established that 70% of the outages, recorded at the source, originate on this feeder.

Full Text Available Comprehensive HIV and AIDS workplace programmes made use of substantial lottery incentives in HIV counselling and testing drives to promote HIV testing at four companies in the automotive industry in the Nelson Mandela Bay Municipality. The main aim was to use lottery incentives to increase uptake for HIV testing. This would help to define company HIV prevalence and ensure timely support, care and treatment of employees. In total, 1 324 employees, making up about 90% of the total staff, were tested for HIV in the four companies during wellness testing days. In order to gain an understanding of employees’ experiences of the lotteries as part of the HIV counselling and testing drive, quantitative data were collected among a total of 414 employees, and 17 interviews were conducted in the four companies. In this article, we investigate the issue of whether the lotteries unduly influenced the employees’ participation in workplace HIV testing, and an approach to resolving an identified ethical dilemma is presented. The ethical question as to whether lottery incentives contribute to undue coercion was explored using both a utilitarian and a deontological approach. The analysis concluded that the use of lotteries to encourage HIV testing in the workplaces of the automotive industry in the Nelson Mandela Bay Municipality can be deemed morally acceptable.

2018-01-01

Background The human immunodeficiency virus and/or acquired immune deficiency syndrome (HIV/AIDS) pandemic continues to increase in prevalence worldwide, particularly in South Africa, and includes the often overlooked paediatric population. The provision of paediatric antiretroviral treatment (ART) is as essential for children as for adults, and has numerous obstacles, not least of which is lack of decentralisation of facilities to provide essential treatment. Optimising ART, care and support for HIV-positive children, and their caregivers, at public sector primary health care (PHC) clinics is crucial to improve morbidity and mortality rates in children. Aim To explore the experiences of health care professionals regarding the provision of ART for children at PHC clinics. Setting The study was conducted in six PHC clinics in Nelson Mandela Bay Health District, Eastern Cape, South Africa. Methodology The researchers used a qualitative, explorative, descriptive and contextual research design with in-depth interviews. We used non-probability purposive sampling. Data collected were thematically analysed using Creswell’s data analysis spiral. We used Lincoln and Guba’s model to ensure trustworthiness. Ethical standards were applied. Results Health care professionals experienced numerous challenges, such as lack of resources, need for training, mentoring and debriefing, all related to providing decentralised ART for HIV-positive children at the PHC level. Conclusion Capacitation of the health care system, integration of services, competent management and visionary leadership to invoke a collaborative interdisciplinary team approach is required to ensure that HIV is treated as a chronic disease at the PHC clinic level.

Appendicectomy is the most commonly performed operation worldwide. The diagnosis is predominantly based on clinical findings. Some patients will clinically be unclear if ruptured or acute inflamed appendicitis; the level of white cell count has been used as the predictor for ruptured appendicitis. This was a retrospective chart review of paediatric surgical patients admitted at Nelson Mandela Central Hospital, Mthatha South Africa. A total of 214 patients with a diagnosis of acute appendicitis. Overall, the ruptured appendicitis was 62% and 38% were inflamed appendicitis. Nature of the acute appendicitis: White cell count, Inflamed, Ruptured, Total p-value 30 0 4 4. This study has demonstrated that in patients who are diagnosed with acute appendicitis clinically, the normal white cell count does not necessarily rule out ruptured acute appendicitis. But the risks of ruptured acute appendicitis increase with the increase level of white cell count.

Mourning Mandela: sacred drama and digital visuality in Cape Town

Directory of Open Access Journals (Sweden)

Paula Uimonen

2015-12-01

Full Text Available The world united in unprecedented ways in mourning the global icon Nelson Mandela, an emotionally charged historical event in which digital visuality played an influential role. The memorial service for Nelson Mandela on Tuesday, 10 December 2013, gathered dignitaries and celebrities from around the world at the First National Bank Stadium in Johannesburg, to mourn the passing of Madiba and to celebrate his life work. At the Grand Parade in Cape Town, the event was broadcast on large public screens, followed by live music performances and narrowcast interaction with the audience. Building on recent research on public screens during global media events, this article addresses the mediated mourning rituals at the Grand Parade in terms of a sacred drama. Focusing on social relationality, the article discusses how digital visuality mediated a sense of global communitas, thus momentarily overcoming historical frictions between the global north and the global south, while expanding the fame of Madiba. Paying attention to the public display of visual memory objects and the emotional agency of images, it argues that digital visuality mediated social frictions between the living and the dead, while recasting a historical subject as a historical object. The article further discusses how digital visuality mediated cultural frictions of apartheid and xenophobia, through the positioning of Mandela in the pantheon of Pan-African icons, thus underlining the African origin of this global icon. The analysis is based on ethnographic observations and experiences in Cape Town.

Romance and Freedom: Nelson and Winnie Mandela’s Politics of Gender in Three Post-Apartheid Novels

Directory of Open Access Journals (Sweden)

Lorenzo Mari

2014-11-01

Full Text Available This paper aims to retrace the influence of the politics of gender enacted by Nelson and Winnie Mandela on post-apartheid gender relationships, as represented in three novels: Phaswane Mpe’s Welcome to Our Hillbrow (2001, Njabulo Ndebele’s The Cry of Winnie Mandela (2003 and Lewis Nkosi’s Mandela’s Ego (2006. Recently, Nelson and Winnie Mandela’s marriage has been also described as the “unusual founding-family romance” (Munro 2014 of the post-apartheid nation. Their marriage lasted from 1958 to 1992, including, thus, the last decades of the anti-apartheid struggle, as well as the demise of the apartheid regime. Their separation, which was due in the first place to Nelson Mandela’s imprisonment and, later, to their divorce, eventually marked the disruption of this founding-family romance, making it “unusual”. As a consequence, the deconstructive take on Nelson Mandela’s fatherhood and masculinity and Winnie Mandela’s femininity and motherhood which is enacted in the three novels also allows to reassess the possibility of that “founding-family romance”, envisioning an alternative understanding of the origins of the post-apartheid South African nation.

Nelson Mandela’s ‘Ordinary Love’ Addressed in Pop-rock Music: a Long Song of Freedom

Directory of Open Access Journals (Sweden)

Simona Martini

2014-11-01

Full Text Available This paper aims to highlight how inspirational the figure of Nelson Mandela has been for several musicians and songwriters. In particular, it focuses on songs written by Western musicians from the early Eighties until 2013 – all showing the extent to which the South African leader has epitomized the struggle for equality and freedom. This study points out how the success of a hit single in 1984 – British ska group The Special AKA’s “Free Nelson Mandela” – paved the way for a quick increase in the number of musicians who got involved in the anti-apartheid movement and contributed to make Western audiences know about Mandela and increasingly demand that apartheid be put to an end. This survey seeks to examine the main achievements in pop-rock songs that generated both from the growing awareness about the South African leader’s experience when he was imprisoned, and the legacy of his exemplum after he was set free. Among the songs cited: Simple Minds’ “Mandela Day”, the various artists’ tribute “46664” and the most recent Golden Globe-awarded “Ordinary Love” by U2, written for the soundtrack of the biopic The Long Walk to Freedom. To better understand how the figure of Mandela has been addressed in these works, the paper includes analyses of the most complex and significant lyrics among the songs discussed, thus also showing how the South African cultural background as it was received by the West could have informed the songwriting, and how the Western reception of such songs determined an increasing awareness about Mandela’s plight and the whole phenomenon of apartheid.

The archive of the radiology departments at Umtata General Hospital and Nelson Mandela Academic Hospital in the Transkei region, Eastern Cape Province, SA, was searched retrospectively for computed tomography (CT) reports of patients diagnosed with ICS. Cases in which the CT images, patients' clinical information and CT reports were available for an uninterrupted period of at least 1 year were included. Five time frames were established, encompassing 8 years of data. The first time frame established an incidence of ICS of 1/100,000/year for the Transkei region. All the time frames were utilised to determine the incidence according to gender and age, and the source and distribution of ICS. The incidence of ICS was higher among males than females, and highest in the age groups 0-10 and 11-20 years. A seasonal variation in the incidence of sinusitis- and meningitis-related ICS was noted. Numbers of cases declined during the last 3 years of the study period. Sinusitis, head trauma, ear infection and meningitis were the major sources of ICS. A pulmonary source was not a major feature. In the last 4 years, trauma became the commonest source of ICS. A steady decline in ear infection- and meningitis-related ICS was noted.

Mandela restores morale of AIDS conference.

2000-07-22

During the 13th international AIDS conference in Durban, former president Nelson Mandela pulled the morale of the conference highlighting the need to confront the needs and concerns of those suffering and dying of HIV/AIDS in South Africa, mostly in sub-Saharan. He also stated that to challenge the grave threat posed by HIV and AIDS, efforts should be combined to save the people. This concluding remark was in direct contrast to the opening words of South Africa's current president, Thabo Mbeki, who failed to deal with the impression he has created internationally that he has doubts about the etiology of AIDS. In addition, the need to focus on the accessibility and affordability of treatment for HIV/AIDS or the opportunistic infections associated with it was highlighted. The conference focused on this issue with the help of AIDS activists, who emphasized that pharmaceutical companies needed to address how their drugs could reach those who most need them.

Framing Mandela: An (InterNational Comparative News Analysis of the Iconic Leader’s Death

Directory of Open Access Journals (Sweden)

Tania Cantrell Rosas-Moreno

2017-05-01

Full Text Available Few studies have investigated how the press covers political leaders’ deaths and the societal, cultural and political connotations of such coverage. Even fewer have tackled the topic when that leader is black. We use Framing Theory applied through an interpretive textual analysis to over 80 news articles from two South African and two Brazilian dailies to understand how Nelson Mandela—a black iconic leader—was framed in the 11 days straddling his death and death events. These two countries were selected, because South Africa was Mandela’s home, and Brazil has the largest Black population of any country outside of Africa. Additionally, both nations are locked in partnerships, including their participation in BRICS and IBSA. Comparing and contrasting seven emergent frames points to the need to consider the social construction of the collective memory of his death as pursuant to understanding Mandela’s legacy.   Até agora poucos estudos investigaram como a imprensa cobre a morte de líderes políticos, e as consequentes conotações sociais, culturais e políticas dessa cobertura. Ainda menos estudos abordam o tema quando se trata de um líder negro. Utilizamos a Teoria do Enquadramento, aplicada através de uma análise textual interpretativa a mais de 80 artigos de notícias de dois jornais sul-africanos e dois brasileiros para entendermos como Nelson Mandela - um líder icônico negro - foi enquadrado nos 11 dias entre sua morte e os eventos ao redor da mesma. Estes dois países foram selecionados, porque a África do Sul era a nação de Mandela, e o Brasil devido ao fato de ter a maior população negra de qualquer país além da África. Além disso, essas nações são parceiras já que fazem parte dos BRICS e IBSA. Ao compararmos e contrastarmos sete quadros emergentes dessa cobertura, apontamos para a necessidade de considerarmos a construção social da memória coletiva de sua morte como modo de compreendermos o legado da

Choice of speciality amongst first-year medical students in the Nelson R. Mandela School of Medicine, University of KwaZulu-Natal

Science.gov (United States)

Naidu, Edwin; Naidu, Jesse

2013-01-01

Abstract Background Trends in career choice amongst medical graduates have considerable implications for the percentage of the workforce available for training. Objective To investigate and review factors affecting career choice by undergraduate first-year medical students. Method This was a cross-sectional study using a closed-ended, semi-structured survey instrument. Two hundred and four questionnaires were administered to all first-year medical students at the Nelson R. Mandela School of Medicine in the first term of the 2012 academic session. Results The questionnaire was completed by 167 out of 204 students (81.8% response rate). Most of the respondents were South Africans (91%) and blacks (72%), with a higher proportion of women to men (2:1). The majority (86%) intended to undertake their postgraduate training in surgical specialties (53%), general surgery (50%) and cardiology (46%). Few were interested in an academic career in basic sciences (27.6%), either because they were not interested in research and/or teaching (48%), not clinically-orientated (20%), or found it to be an unattractive choice (12.3%). The top perceived career-related factors favouring choice of speciality were personal interest and benefits to patients as many (83%) respondents still viewed the medical profession as having a bright future in South Africa. Conclusions Our study highlighted the fact that self and patient interests were strong determinants of speciality choices by the students and the role of parents and practice in rural areas were considered least as potential influencing factors. This would appear to be a good indicator that the healthcare sector may be boosted in the future by doctors who are wholeheartedly committed to the service of the communities with the greatest disease burden.

Assimilating South African medical students trained in Cuba into the South African medical education system: reflections from an identity perspective

Directory of Open Access Journals (Sweden)

B. M. Donda

2016-10-01

Full Text Available Abstract Background In terms of the Nelson Mandela Fidel Castro Medical Collaboration programme, an agreement between the governments of South Africa and Cuba, cohorts of South African students receive their initial five years medical training at a Cuban university before returning to South Africa for a six to twelve months orientation before integration into the local final year class. It is common for these students to experience academic difficulty on their return. Frequently this is viewed merely as a matter of a knowledge deficit. Discussion We argue that the problem arises from a fundamental divergence in the outcomes of the Cuban and South African medical curricula, each of which is designed with a particular healthcare system in mind. Using the discrepancy theory of identity proposed by Higgins in 1987, we discuss the challenges experienced by the returning Nelson Mandela Fidel Castro Medical Collaboration students in terms of a potential crisis of identity and suggest interventions which may prove valuable in promoting academic success and successful integration. Conclusions Though providing additional training to address the gap in skills and knowledge in returning students is an important part of their successful reintegration, this could be insufficient on its own and must be complemented by a range of measures designed to ameliorate the discrepancies in identity which arise from the transition from one educational model to another.

Mandela calls for greater commitment and leadership in fighting AIDS. The World Economic Forum -- Policy and business in a world of HIV / AIDS.

Macinnis R

1997-01-01

The 27th annual meeting of the World Economic Forum in Davos, Switzerland, on February 3, 1997, was attended by 2000 political and financial leaders of countries and businesses around the world. The forum is the world's largest annual gathering of economic and political dignitaries. In his address to the forum, Nelson Mandela, president of South Africa, called for a global effort against AIDS and a strengthening of the world's political and business leaders' commitment against HIV/AIDS. The disease is creating global economic problems by affecting people in their prime productive and reproductive years. Mandela criticized political leaders for their limited actions in addressing the AIDS pandemic and called upon the world's business community to support government AIDS programs and help people affected by AIDS. All sectors and all spheres of society must be involved as equal partners in the war against HIV/AIDS, for neither the health sector nor government can meet the challenge on its own. If current HIV/AIDS trends continue in South Africa, AIDS will cost the country 1% of its domestic gross product by the year 2005, and up to 75% of the country's budget will be consumed by direct health costs related to HIV/AIDS. At a panel discussion preceding President Mandela's address, Dr. Peter Piot, executive director of UNAIDS, argued that the AIDS pandemic could have a devastating effect upon the global economy and urged business leaders to take strong action against the disease.

Revisiting the Master-Signifier, or, Mandela and Repression.

Science.gov (United States)

Hook, Derek; Vanheule, Stijn

2015-01-01

The concept of the master-signifier has been subject to a variety of applications in Lacanian forms of political discourse theory and ideology critique. While there is much to be commended in literature of this sort, it often neglects salient issues pertaining to the role of master signifiers in the clinical domain of (individual) psychical economy. The popularity of the concept of the master (or "empty") signifier in political discourse analysis has thus proved a double-edged sword. On the one hand it demonstrates how crucial psychical processes are performed via the operations of the signifier, extending thus the Lacanian thesis that identification is the outcome of linguistic and symbolic as opposed to merely psychological processes. On the other, the use of the master signifier concept within the political realm to track discursive formations tends to distance the term from the dynamics of the unconscious and operation of repression. Accordingly, this paper revisits the master signifier concept, and does so within the socio-political domain, yet while paying particular attention to the functioning of unconscious processes of fantasy and repression. More specifically, it investigates how Nelson Mandela operates as a master signifier in contemporary South Africa, as a vital means of knitting together diverse elements of post-apartheid society, enabling the fantasy of the post-apartheid nation, and holding at bay a whole series of repressed and negated undercurrents.

Impressions of health in the new South Africa: a period of convalescence.

Kale, R

1995-04-29

The White minority population in South Africa long oppressed and disenfranchised the country's Black majority. The apartheid system, however, was finally put to rest with the election of Nelson Mandela as President of South Africa during April 27-29, 1994. During apartheid, the White minority enjoyed the best health care available among developed countries, while Blacks were forced to receive some of the worst care provided in the Third World. The doctor/patient ratios in 1981 for White and Black patients, respectively, were 330 and 91,000. In 1985, infant mortality for White infants was 13.1/1000 compared to 70/1000 for Blacks. The existence of fourteen separate health departments caused major duplication and waste. South Africa now has the opportunity to effect revolutionary changes in its health care. To that end, President Mandela announced free health care for pregnant women and children younger than age six years on May 24, 1994. A subsequent uptake in health service utilization was quickly observed in small towns. Structurally, a central health department with a provincial department for each of the four provinces replaced the redundant predemocracy system of fourteen health departments. This change, however, for now, exists only on paper and net financial gains from the reorganization have yet to be realized. Finally, there have been frequent strikes in hospitals throughout the country by health workers demanding better pay and working conditions.

Um exemplo típico é o Nelson Mandela Bay Metropole na África do Sul, onde 100.000 unidades habitacionais precisam ser construídas em um período de três a cinco anos para acabar com o déficit. A quantidade de dados relativos a uma única habitação é vasta e, em um grande empreendimento, ainda mais significativa. Tradicionalmente, os dados são armazenados em vários locais, por exemplo, com autoridades governamentais, arquitetos ou outros profissionais, empreendedores, subcontratados, agentes imobiliários, instituições financeiras ou proprietários. Baixa eficiência e atrasos substanciais são o resultado, quando os dados existentes não podem ser acessados rapidamente, ou não são encontrados. Um processo de localização espacial e sistema de controle de dados física e inequivocamente associado com cada particular unidade habitacional foi desenvolvido para resolver com sucesso a maioria desses problemas.

South Africa (SA) has the highest burden of childhood HIV infection globally, and has high rates of adolescent and youth pregnancy. To explore risks associated with pregnancy in young HIV-infected women, we compared mother-to-child transmission (MTCT) of HIV and maternal and infant health outcomes according to maternal age categories. A cohort of HIV-positive pregnant women and their infants were followed up at three sentinel surveillance facilities in the Nelson Mandela Bay Metropolitan (NMBM) district, Eastern Cape Province, SA. Young women were defined as 24 years old and adolescents as 19 years. The effect of younger maternal age categories on MTCT and maternal and child health outcomes was assessed using log-binomial and Cox regression controlling for confounding, using women aged > 24 years as the comparison group. Of 956 mothers, 312 (32.6%) were young women; of these, 65 (20.8%) were adolescents. The proportion of young pregnant women increased by 24% between 2009/10 and 2011/12 (from 28.3% to 35.1%). Young women had an increased risk of being unaware of their HIV status when booking (adjusted risk ratio (aRR) 1.37; 95% confidence interval (CI) 1.21 - 1.54), a reduced rate of antenatal antiretroviral therapy (ART) uptake (adjusted hazard ratio 0.46; 95% CI 0.31 - 0.67), reduced early infant HIV diagnosis (aRR 0.94; 95% CI 0.94 - 0.94), and increased MTCT (aRR 3.07; 95% CI 1.18 - 7.96; adjusted for ART use). Of all vertical transmissions, 56% occurred among young women. Additionally, adolescents had increased risks of first presentation during labour (aRR 3.78; 95% CI 1.06 - 13.4); maternal mortality (aRR 35.1; 95% CI 2.89 - 426) and stillbirth (aRR 3.33; 95% CI 1.53 - 7.25). An increasing proportion of pregnant HIV-positive women in NMBM were young, and they had increased MTCT and poorer maternal and infant outcomes than older women. Interventions targeting young women are increasingly needed to reduce pregnancy, HIV infection and MTCT and improve maternal

Disclosing details about the medical treatment of a deceased public figure in a book: Who should have consented to the disclosures in Mandela's Last Days?

Science.gov (United States)

McQuoid-Mason, D J

2017-11-27

A recently published book by the head of Nelson Mandela's medical team made personal disclosures about his treatment of the late president in his final years up until his death. The author claimed that he had written the book at the request of family members. This was contested by some family members and the executors of Mandela's estate, and the book was subsequently withdrawn by the publishers. The Mandela book case raises ethical and legal questions about who should consent to publication of medical information about public figures after their death. The ethical rules of conduct of the Health Professions Council of South Africa (HPCSA) state that confidential information about a deceased person should only be divulged 'with the written consent of his or her next of kin or the executor of his or her estate'. 'Next of kin' is not defined, however, and problems arise when family members and the executors are divided about giving such written consent. It is recommended that in such cases the specific order of priority for consent by relatives in the National Health Act be followed. However, conduct that is unethical under the rules of the HPCSA may not necessarily be actionable under the law. For instance, the law does not protect the confidentiality of deceased persons, and generally when people die their constitutional and common-law personality rights - including their right to privacy and confidentiality - die with them. This means that the next of kin or executors of the estates of deceased persons may not bring actions for damages on behalf of such persons for breaches of confidentiality arising after their deaths. The next of kin may, however, sue in their personal capacity if they can show that the disclosures were an unlawful invasion of their own privacy. Conversely, if the privacy of interests of the next of kin are not harmed where there has been publication without their consent, they will not be able to sue for damages.

Key findings: a qualitative assessment of provider and patient perceptions of HIV/AIDS in South Africa.

Science.gov (United States)

Ransom, James; Johnson, Anton F

2009-01-01

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

A synopsis of South African psychology from apartheid to democracy.

Science.gov (United States)

Cooper, Saths

2014-11-01

In this concatenated overview, the development of psychology in South Africa is traced from its origins in the late 19th century to the present. The seminal influences on the science and practice of psychology of the racialized polity and the responses to the prevailing regimen are also explored. The significant events in the patinated layers of psychological discourse and consequent policies in these constrained circumstances are traversed. Despite the nonracial era occasioned by the formation of the Psychological Society of South Africa three months before the advent of democracy under Nelson Mandela in 1994, the profession of psychology remains demographically skewed. Nevertheless, psychology in the current democratic dispensation enjoys a high profile and is actively engaged in ongoing and reflexive self-examination to ensure that it is more accessible and truly serves humanity. If Africa is psychology's last frontier, the critical denouement of the various issues confronting psychology in the southern tip of the African continent will provide a positive growth path that is likely to merit attention beyond its borders.

Nelson syndrome: definition and management.

Science.gov (United States)

Barber, T M; Adams, E; Wass, J A H

2014-01-01

Nelson syndrome is an important complication of treatment with total bilateral adrenalectomy (TBA) for patients with refractory Cushing's disease. Although early cases of Nelson syndrome often presented with the clinical features of large sellar masses, the modern face of Nelson syndrome has changed primarily due to earlier detection (with highly resolved magnetic resonance imaging (MRI) and sensitive ACTH assays) and greater awareness of the condition, resulting in reduced morbidity and mortality. Although lack of administration of neoadjuvant pituitary radiotherapy post-TBA surgery may predict future development of Nelson syndrome, other predictive factors remain controversial. Therefore, Nelson syndrome should be screened for closely and long-term in all patients with a history of Cushing's disease and TBA. The diagnosis of Nelson syndrome remains controversial, and the pathogenesis of this condition is incompletely understood. Current hypotheses include the "released negative feedback" mechansism (residual pituitary corticotropinoma cells are "released" from the negative feedback effects of cortisol following TBA), and the "aggressive corticotropinoma" mechanism (Nelson syndrome is most likely to develop in those patients with refractory treatments - including TBA - for an underlying aggressive corticotropinoma). Effective management of Nelson syndrome with pituitary surgery and radiotherapy is often a challenge. Other therapies (such as Gamma Knife surgery and temozolomide) play an important role and merit further research into their efficacy and placement in the management pathway of Nelson syndrome. © 2014 Elsevier B.V.

Although several clinical and biological markers of preeclampsia have been evaluated, they have proven to be ineffective in providing a definitive diagnosis during the various stages of the disorder. Exosomes have emerged as ideal biomarkers of pathological states, such as cancer, and have more recently gained interest in pregnancy-related complications, due to their role in cellular communication in normal and complicated pregnancies. This occurs as a result of the specific placenta-derived exosomal molecular cargo, which may be involved in normal pregnancy-associated immunological events, such as the maintenance of maternal–fetal tolerance. This review provides perspectives on placenta-derived exosomes as possible biomarkers for the diagnosis/prognosis of preeclampsia. Using keywords, online databases were searched to identify relevant publications to review the potential use of placenta-derived exosomes as biomarkers of preeclampsia.

To review the pathophysiology and therapeutic modalities availble for Nelson syndrome. We reviewed the current literature including managment for Nelson syndrome. For patients with NS, surgical intervention is often the first-line therapy. With refractory NS or tumors with extrasellar involvement, radiosurgery offers an important alternative or adjuvant option. Pharmacologic interventions have demonstrated limited usefulness, although recent evidence supports the feasibility of a novel somatostatin analog for patients with NS. Modern neuroimaging, improved surgical techniques, and the advent of stereotactic radiotherapy have transformed the management of NS. An up-to-date understanding of the pathophysiology underlying Nelson Syndrome and evidence-based management is imperative. Early detection may allow for more successful therapy in patients with Nelson Syndrome. Improved radiotherapeutic interventions and rapidly evolving pharmacologic therapies offer an opportunity to create targeted, multifocal treatment regiments for patients with Nelson Syndrome.

Music and dance make me feel alive: from Mandela's prison songs and dances to public policy.

Science.gov (United States)

Buis, Johann S

2013-01-01

How is it possible for song and dance to exist in political incarceration and manifest itself later as public policy responding to apartheid atrocities? Examining the body of songs, oral history accounts, and eye-witness reports provided by fellow-prisoners of Mandela on Robben Island prison, I uncover a psychological environment mediated through music and dance--within the confines of a political prison. This source of prison music-making by political prisoners in detention, provide us with the artistic expressions of revolutionary songs, parody songs, praise songs, laments, etc. These music genres reflect ontologies embedded in Mandela's juristic imagination. My framework for explaining these ontologies is a theoretical framework I call an aesthetic of function: internal ontologies that speak to the African cultural ground against which external ontologies are expressed in the jurisprudential redress to apartheid atrocities. Examining his external (jurisprudential) ontologies through song and dance, one realizes that the best way for him to have solved the unprecedented public redress of apartheid atrocities is evident in the songs he sang in Robben Island prison. Retribution could have been a logical solution for him. Instead, he turned to truth-telling and reconciliation as public policy. The Truth and Reconciliation Commission's unprecedented breaking of social and jurisprudential boundaries, the claim of agency for both victims and perpetrators, and public policy of South Africa's first democratically elected black president, lie deeply embedded in cultural practices he testified to in his autobiography, "The Long Walk to Freedom". These cultural practices in prison were singing and dancing. This paper complements the music-as-torture trope: here music in detention carries ontological agency. Musical evidence of stylistic features, text, and contextual analyses, and related literary criticism devices, expose Mandela's embedded internal and external

Product spaces and Nelson's inequality

International Nuclear Information System (INIS)

Faris, W.G.

1976-01-01

Certain inequalities for unbounded linear operators in L 2 extend to product spaces. This product space property is used to give a new proof that Gross's inequality for matrices implies Nelson's inequality for ordinary differential operators, and that this in turn implies Nelson's inequality for partial differential operators in infinitely many dimensions. A new proof of Gross's inequality is given. There is also a discussion of the physical meaning of Nelson's inequality in quantum field theory. The article may serve as an introduction for non-specialists to some of the recent mathematical work in this subject. (Auth.)

Citizens and personal health records - the case of Nelson Mandela Bay.

Science.gov (United States)

Pottas, Dalenca; Mostert-Phipps, Nicky

2013-01-01

This paper explores citizen attitudes towards personal health records. The study was conducted in the Eastern Cape Province of South Africa. A cross-sectional design was used and structured questionnaires administered by data collectors. Most respondents (90%) believed it to be important to extremely important for their healthcare provider to have their complete medical records. Less than half of them (42%), however, believed that the healthcare provider did have their complete medical record available to them. Nevertheless, 69% do not keep a medical record as a way to address this concern. Most of them (84%) were not aware of the existence of electronic tools to capture a personal health record prior to participating in the survey. Concerns relating to the use of online PHRs were identified as privacy (58%), lack of time (27%) and a disinterest in computers (22%). It was found that the existence of a medical chronic condition is a strong predictor of keeping a medical record (albeit mostly in paper-based format).

Two new marine Gastrotricha from the Indian Ocean coast of South Africa.

Todaro, M Antonio; Perissinotto, Renzo; Bownes, Sarah J

2015-01-12

The study is part of a larger research programme aimed at shedding light on the gastrotrich communities of the subtropical east coast province of KwaZulu-Natal, South Africa. In previous papers, faunistic and preliminary taxonomic data on marine and freshwater gastrotrichs found in the iSimangaliso Wetland Park, were reported. Here two new interesting marine macrodasyidan species in the families Dactylopodolidae and Thaumastodermatidae are described based on observations carried out on living specimens and using differential interference contrast microscopy. The two novel species are named in honor of two great South African icons recently deceased: Nadine Gordimer and Nelson Mandela. Dactylopodola nadine sp. n. is the third species in the genus to bear red eye-spots; it can easily be distinguished from the closely-related red-eyed D. baltica and D. roscovita by its smaller size (Total length = 230 μm vs 275 μm vs 450 μm, respectively) and the lower number of adhesive tubes of the anterior, lateral and posterior series (on each side: 3, 4 and 4 vs 5, 6 and 8 vs 2, 9 and 12-15). Pseudostomella mandela sp. n. is a fairly large species (up to 481 μm in length), with a cuticular covering made up of tetrancres and relatively long caudal pedicles (up to 44 μm in length ). The most evident autoapomorphic trait of the new species is the presence of 7 pairs of 'cirrata' tubes, two emerging in a lateral position along the pharyngeal region and five from the dorsolateral sides of the trunk. Additional relevant taxonomic characters include: 4 tubes of the anterior series, 11 tubes of the ventrolateral series and 3 tubes of the posterior series per side, 5 papillae on the dorsal margin and 6 papillae on the ventral margin of the oral palps. The high number of putative new species discovered among the South African gastrotrich fauna during our relatively short survey, highlights the relevance of this region with regard to the diversity of this group and stresses once again

Search for a particle with a long interaction length. [particle mandela to explain anomalous energy spectra at mountain altitude

A search has been carried out for a long-lived particle having an interaction length lambda sub m equals 300 to 2000 gm/sq cm in air. Such a particle, called the mandela, has been proposed to explain an anomalous energy spectrum of particles observed near sea level with a shallow spectrometer. Data taken at mountain altitude with a deep spectrometer has been examined for compatibility with the existence of the mandela. Although data tend to favor the mandela hypothesis the results are not conclusive and appear to be explainable by conventional means.

Editorial for Journal of Human Security Volume 10

Full Text Available Nelson Rolihlahla Mandela's death on 5 December 2013 and his funeral ten days later were taken as an occasion in the global media to discuss the merits of political leadership for human security, with occasional comments on its pitfalls. This particular leader is not the most politically safe object of discussion, as, for a long time, he openly advocated civil disobedience and resistance, initially of the non-violent kind, but later becoming violent. Predictably, the local hegemon reacted with great brutality and sweeping measures to the resistance of the ANC, policies that shocked many in the western world. This reaction by the gov­ernment and its supporters and the counterreaction it incited amounted, in the long run, to little more than a vast reduction in human security for most citizens of South Africa, lasting until the ANC's victory and Mr Mandela's ascendance to the presidency in 1994.

Full Text Available The sisters of the Brethern Church. A story of women in the Moravian Church in South AfricaThe story of early women converts of the Moravian Church is told. It is argued that this church, since it commenced with missionary work in South Africa in 1737, showed a positive and reconstructive attitude towards women. Presently many so-called coloured women hold high positions in the ministry and moderamen of this church. It is therefore appropriate thatNelson Mandela called his Cape Town residence "Genadendal" in commemoration of the first Moravian mission slation in South Africa and the work done there for the past three cellluries in service of human dignity. As such it is also appropriate to dedicaTe this ankle to Carl Borchardt for his inclusive attitude towards women colleagues.

Nelson syndrome: historical perspectives and current concepts.

2007-01-01

The appearance of an adrenocorticotropic hormone (ACTH)-producing tumor after bilateral adrenalectomy for Cushing disease was first described by Nelson in 1958. The syndrome that now bears his name was characterized by hyperpigmentation, a sellar mass, and increased plasma ACTH levels. The treatment of Cushing disease has changed drastically since the 1950s, when the choice was adrenalectomy. Thus, the occurrence, diagnosis, and treatment of Nelson syndrome have changed as well. In the modern era of high-resolution neuroimaging, transsphenoidal microneurosurgery, and stereotactic radiosurgery, Nelson syndrome has become a rare entity. The authors describe the history of the diagnosis and treatment of Nelson syndrome. In light of the changes described, the authors believe this disease must be reevaluated in the contemporary era and a modern paradigm adopted.

Una perspectiva sobre la transición política en Suráfrica

Directory of Open Access Journals (Sweden)

Macharia Munene

2012-03-01

Full Text Available Suráfrica fue el primer país en sufrir una colonización considerable y la última en terminar con un Gobierno oficial formado por gente blanca. La Suráfrica racista había gobernado Namibia en representación, primero, de la Liga de Naciones y, posteriormente, de las Naciones Unidas. En Suráfrica se afianzaron las estructuras de Gobierno oficiales racistas justo en el momento en que el resto del mundo condenaba el racismo. El país aprovechó la Guerra Fría para reivindicarse como bastión de la civilización occidental en África contra las comunidades negras de inspiración comunista. Las mismas estructuras se mantuvieron vigentes aproximadamente cuarenta años después de que el resto de países africanos hubiese obtenido la independencia política. Las continuas presiones en el propio país y en el ámbito internacional obligaron a Suráfrica a abandonar la estructura política del apartheid. A comienzos de 1990, el país inició un periodo de transición que tuvo que llevarse a cabo con precauciones para evitar el caos. Los dos hombres que lograron el cambio fueron el entonces presidente Frederick de Kierk, que representaba los intereses de los blancos, y el prisionero al que él mismo liberó en 1990, Nelson Mandela, que encarnaba las aspiraciones de la gente negra. La tarea de Mandela consistió en crear un estado de confianza en la nueva Suráfrica y consiguió cambiar la imagen del país, que pasó de tener la consideración de Estado racista inaceptable a convertirse en un elemento clave de África en las negociaciones internacionales. Cuando Mandela dejó la presidencia, su adjunto Thabo Mbeki asumió el cargo y tuvo que afrontar cuestiones a largo plazo sobre la política de la transición. South Africa was first to suffer substantial colonial settlement and the last to end rule by white people officially ruled. Racist South Africa had ruled Namibia on behalf of, first League of Nations and then the United Nations

Mandelalides A-D are variously glycosylated, unusual polyketide macrolides isolated from a new species of Lissoclinum ascidian collected from South Africa, Algoa Bay near Port Elizabeth and the surrounding Nelson Mandela Metropole. Their planar structures were elucidated on submilligram samples by comprehensive analysis of 1D and 2D NMR data, supported by mass spectrometry. The assignment of relative configuration was accomplished by consideration of homonuclear and heteronuclear coupling constants in tandem with ROESY data. The absolute configuration was assigned for mandelalide A after chiral GC-MS analysis of the hydrolyzed monosaccharide (2-O-methyl-α-L-rhamnose) and consideration of ROESY correlations between the monosaccharide and aglycone in the intact natural product. The resultant absolute configuration of the mandelalide A macrolide was extrapolated to propose the absolute configurations of mandelalides B-D. Remarkably, mandelalide B contained the C-4' epimeric 2-O-methyl-6-dehydro-α-L-talose. Mandelalides A and B showed potent cytotoxicity to human NCI-H460 lung cancer cells (IC(50), 12 and 44 nM, respectively) and mouse Neuro-2A neuroblastoma cells (IC(50), 29 and 84 nM, respectively).

Nelson River and Hudson Bay

Science.gov (United States)

2002-01-01

Rivers that empty into large bodies of water can have a significant impact on the thawing of nearshore winter ice. This true-color Moderate Resolution Imaging Spectroradiometer (MODIS) image from May 18, 2001, shows the Nelson River emptying spring runoff from the Manitoba province to the south into the southwestern corner of Canada's Hudson Bay. The warmer waters from more southern latitudes hasten melting of ice near the shore, though some still remained, perhaps because in shallow coastal waters, the ice could have been anchored to the bottom. High volumes of sediment in the runoff turned the inflow brown, and the rim of the retreating ice has taken on a dirty appearance even far to the east of the river's entrance into the Bay. The sediment would have further hastened the melting of the ice because its darker color would have absorbed more solar radiation than cleaner, whiter ice.

Nelson`s syndrome associated with a somatic frame shift mutation in the glucocorticoid recepter gene

Energy Technology Data Exchange (ETDEWEB)

Karl, M.; Stratakis, C.A.; Chrousos, G.P.; Katz, D.A.; Ali, I.U.; Oldfield, E.H. [National Inst. of Neurological Disorders and Stroke, Bethesda, MD (United States)] [and others

1996-01-01

Nelson`s syndrome is the appearance and/or progression of ACTH-secreting pituitary macroadenomas in patients who had previously undergone bilateral adrenalectomy for Cushing`s disease. Extremely high plasma ACTH levels and aggressive neoplastic growth might be explained by the lack of appropriate glucocorticoid negative feedback due to defective glucocorticoid signal transduction. To study the glucocorticoid receptor (GR) gene in Nelson`s syndrome, DNA was extracted from pituitary adenomas and leukocytes of four patients with this condition and amplified by PCR for direct sequence analysis. In one of the tumors, a heterozygous mutation, consisting of an insertion of a thymine between complementary DNA nucleotides 1188 and 1189, was found in exon 2. This frame-shift mutation led to premature termination at amino acid residue 366 of the world-type coding sequence, excluding the expression of a functioning receptor protein from the defective allele. The mutation was not detected in the sequence of the GR gene in the patient`s leukocyte DNA, indicating a somatic origin. By lowering the receptor number in tumorous cells, this defect might have caused local resistance to negative glucocorticoid feedback similar to that caused by the presence of a null allele in a kindred with the generalized glucocorticoid resistance syndrome. P53 protein accumulation, previously reported in 60% of corticotropinomas, could not be detected in any of the four pituitary tumors examined by immunohistochemistry. We suggest that a somatic GR defect might have played a pathophysiological role in the tumorigenesis of the corticotropinoma bearing this mutation. 35 refs., 3 figs., 1 tab.

A new look at Bell's inequalities and Nelson's theorem

International Nuclear Information System (INIS)

Schulz, B.

2009-01-01

In 1985, Edward Nelson, who formulated the theory of stochastic mechanics, made an interesting remark about Bell's theorem. Nelson analysed the latter in the light of classical fields that behave randomly. He found that if a stochastic hidden variable theory fulfils certain conditions, the inequality of Bell can be violated. Moreover, Nelson was able to prove that this may happen without any instantaneous communication between the two spatially separated measurement stations. Since Nelson's article got almost overlooked by physicists, we try to review his comments on the theorem. We argue that a modification of stochastic mechanics published recently by Fritsche and Haugk can be extended to a theory which fulfils the requirements of Nelson's analysis. The article proceeds to derive the quantum mechanical formalism of spinning particles and the Pauli equation from this version of stochastic mechanics. Then, we investigate Bohm's version of the EPR experiment. Additionally, other setups, like entanglement swapping or time and position correlations, are shortly explained from the viewpoint of our local hidden-variable model. Finally, we mention that this theory could perhaps be relativistically extended and useful for the formulation of quantum mechanics in curved space-times.

Exploring the management abilities of spaza shop owners in the Nelson Mandela Metropolitan Municipality

Directory of Open Access Journals (Sweden)

Sandra Perks

2010-12-01

Full Text Available South African entrepreneurs have a poor skills record, which often leads to business failure. To effectively manage a spaza shop requires applying management functions and some management skills. The implementation of simple systems can assist spaza shop owners to manage their businesses more successfully and even grow. A quantitative study was done, by interviewing sixty spaza shop owners in the township. The empirical results identified the gaps in the management abilities of spaza shop owners in terms of the eight management functions and show that the purchasing, financial and information management function is the most neglected. Guidelines on how each of the functions could or should be applied are given. This research clearly indicates that spaza shops can assist in economic growth and relieve unemployment in the country.

Kasperlik-Zaluska, A.; Walecki, J.; Brzezinski, J.; Jeske, W.; Migdalska, B.; Bonicki, W.; Brzezinska, A.; Makowska, A.

1997-01-01

The purpose of the study was to evaluate the utility of MRI and CT in the diagnosis of Nelson's syndrome, i. e. pituitary tumours in patients bilaterally adrenalectomized for Cushing's disease. Thirteen patients, followed up for 5-29 years after adrenalectomy, were studied. In 6 of them CT and MRI revealed no changes in the pituitary gland. In the remaining 7 patients only three CT scans were suggestive of a pituitary adenoma. MRI studies with administration of gadodiamide confirmed the CT diagnosis of Nelson's tumour in 3 patients and disclosed microadenomas in a further 4 patients. Neurosurgical treatment in 4 patients confirmed the MRI findings. Additionally CT and MRI examinations were performed in 5 patients suspected of a recurrent Nelson's tumour 3-11 years after neurosurgery. MRI visualized recurrent adenomas in 3 patients that were not well seen by CT scans. In our experience MRI was more effective than CT in the diagnosis of Nelson's syndrome. (orig.).

Physical growth in a transitional economy: the aftermath of South African apartheid.

Science.gov (United States)

Cameron, Noël

2003-01-01

The economic transition in developing countries is not always the result of the change from a centrally-planned to a free-market economy, but may be found within an already existing free-market economy as a result of profound political change, as in South Africa. The release of Nelson Mandela in February 1990 heralded an end both to the political system of apartheid and to the concomitant social, political, and economic disenfranchisement of 30 million non-White people in South Africa. The first freely elected non-White government came to power in 1994 and initiated a number of social and economic reforms aimed at alleviating the worst consequences of apartheid. This paper examines the effect of post-apartheid economic and social transition on the growth and development of urban children. Over 4000 children born in Soweto and Johannesburg were enrolled in the Birth to Ten (BTT) birth-cohort study in 1990. Whilst these children were born with lower birth weights than in developed countries, they did grow strongly in infancy, particularly in weight, to reflect normal reference values for body mass index (BMI) by 1 year of age. While post-apartheid social and economic changes were expected to take some time to affect child growth and development, the rate of change has been slower than expected. Data from the BTT study demonstrate that the growth of White children continues to be superior to that of their non-White peers and differences that existed at birth and during infancy have not diminished during childhood and early adolescence.

Farrar, G.

1993-01-01

This paper reports that continuing a trend starting in 1983, the Nelson-Farrar refinery construction index rose slowly from 1211.6 in January 1990, to 1265.8 in December 1991. The labor component of the index rose at a more rapid rate than did the material component. The labor index rose from 1469.5 to 1558.1 over the 2-year period, while the material index rose only 2.3 points, from 824.9 to 827.2. The miscellaneous equipment index rose 52.1 points in the 2-year comparison. The category includes pumps and compressors, electrical equipment, heat exchangers, instruments, and engines. They are thus manufactured items, and their costs are a measure of manufacturing efficiency. The Nelson-Farrar refinery operations index dropped 5.4 points, from 395.1 to 389.7 in the 1990-1991 period. The process unit index also showed a decrease over this period, dropping from 469.3 to 405.2

Myiasis is the infestation of live tissue of humans and other vertebrates by larvae of flies. Worldwide, myiasis of humans is seldom reported, although the trend is gradually changing in some countries. Reports of human myiasis in Africa are few. Several cases of myiasis were recently seen at the Mthatha Hospital Complex, Mthatha, Eastern Cape Province, South Africa (SA). Because of a paucity of literature on myiasis from this region, surgeons and scientists from Walter Sisulu University, Mthatha, decided to document myiasis cases presenting either at Nelson Mandela Academic Hospital or Umtata General Hospital from May 2009 to April 2013. The objective was to determine the incidence, epidemiology, patient age group and gender, and fly species involved. The effect of season on incidence was also investigated. Twenty-five cases (14 men and 11 women) were recorded in the 4-year study period. The fly species involved were Lucilia sericata, L. cuprina, Chrysomya megacephala, C. chloropyga and Sarcophaga (Liosarcophaga) nodosa, the latter being confirmed as an agent for human myiasis for the first time. The patients were 3 - 78 years old (median 56). Cases were most numerous during spring and summer, and were associated with underlying pathologies typical of ageing. Myiasis is a more common medical condition than expected in the Mthatha region. The study shows that human myiasis is still frequently encountered in SA, and there is a need to understand its epidemiology better.

Challenges for the Nelson-Barr mechanism

International Nuclear Information System (INIS)

Dine, Michael; Draper, Patrick

2015-01-01

The axion and m u =0 solutions to the strong CP problem have been subject to the most careful scrutiny and critique. Basic theoretical issues include hierarchy and fine-tuning problems, quality and genericity of symmetries, and compatibility with solutions to the electroweak hierarchy problem. We study the similar set of challenges for solutions to strong CP based on spontaneous CP violation and the Nelson-Barr mechanism. Some of our observations have appeared in the literature previously, and others are new; our purpose is to collect and analyze the issues as a whole and provide an assessment of the most plausible settings for the Nelson-Barr solution.

On the domain of the Nelson Hamiltonian

Science.gov (United States)

Griesemer, M.; Wünsch, A.

2018-04-01

The Nelson Hamiltonian is unitarily equivalent to a Hamiltonian defined through a closed, semibounded quadratic form, the unitary transformation being explicitly known and due to Gross. In this paper, we study the mapping properties of the Gross-transform in order to characterize the regularity properties of vectors in the form domain of the Nelson Hamiltonian. Since the operator domain is a subset of the form domain, our results apply to vectors in the domain of the Hamiltonian as well. This work is a continuation of our previous work on the Fröhlich Hamiltonian.

To classify and characterize the clinical features of various diabetes classes among young black South Africans. Cross sectional study of 60 black patients with diabetes, all less than 30 years of age and attending Nelson Mandela Academic Hospital, Mthatha, South Africa. Diabetes was classified as Types 1A, 1B and 2 based on the anti-glutamic acid decarboxylase status and serum C-peptide response to intravenous injection of glucagon. Mean age was 19.6±4.8 years (n=60) with similar gender distribution. The mean duration of diabetes was 24.2±45.1 months. Type 1A was the class of diabetes in 55% (n=33/60) of patients. Type 1B and 2 accounted for 30% (n=18/60) and 15% (n=9/60) of patients respectively. Patients classified as Type 2 had higher waist circumference and higher prevalence of acanthosis nigricans than Types 1A and 1B groups. History of diabetes in a first degree relative and hypertension were found in similar proportions of patients with Types 1A, 1B and 2 diabetes. Five Type 1A diabetes patients had body mass index of 26.2-41kg/m(2) and this included two newly diagnosed patients with body mass index of 26.7kg/m(2) and 33.2kg/m(2). The majority of our young black South Africans with diabetes are of the Type 1A class. Acanthosis nigricans was not found in any patient with Type 1 A diabetes. A minority of Type 1 A diabetes patients were obese at initial diagnosis. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

MT-loaded nanoparticles were formulated by a water-in-oil-in-water emulsion technique using 50, 75, and 100 mg of stearic acid, 2% and 3% w/v polyvinyl alcohol, 5% w/v lactose, and 0.2% w/v chitosan. The emulsions were immediately spray-dried based on an optimized model of inlet temperature and pump rate, and characterized for optimized responses with regard to particle size, polydispersity index, and zeta potential, for both emulsion and powder samples. Dynamic light scattering analysis shown that the nanoparticles increased in size with increasing concentrations of polyvinyl alcohol and stearic acid. Scanning electron microscopy indicated that the MT-loaded nanoparticles were spherical in shape, had a smooth surface, and were in an amorphous state, which was confirmed by differential scanning calorimetry. These MT-loaded nanoparticles are a promising candidate carrier for the delivery of MT; however, further studies are needed in order to establish the stability of the system and the cargo release profile under normal conditions of use.

Persuasive strategies in Mandela’s No Easy Walk to Freedom

Directory of Open Access Journals (Sweden)

Ali Abdulhameed Faris

2016-01-01

Full Text Available Remarkable politicians are those who are skilled at communicating their ideas with a good sense of persuasion. The present paper is an endeavour to investigate the persuasive strategies of the African leader, Nelson Mandela, with reference to his address No Easy Walk to Freedom (1953. Johnstone’s (2008 framework for persuasive strategies was used for the analysis. The findings demonstrate the use of three persuasive strategies – quasilogical, presentational and analogical. Quasilogical argumentation, which is based on rationality, was made through syllogism, enthymeme and causation. To create involvement, Mandela manipulated presentational persuasion via rhetorical deixes, metaphors, repetition and alliteration. Attempting to elevate the spiritual values of his addressees in regard to the cause of liberation and freedom, Mandela employed analogical persuasion by making a reference to the Bible. Of these three strategies, quasilogical and presentational strategies were the most manipulated by Mandela in the given speech to move his audience. Logic and rationality was used to motivate his audience to receive his claims about white supremacy, andemotions mainly grief and rage were evoked to energize the course of anti-white supremacy non-violent orchestrated struggle.

This paper presents our 18 years of experience in treating ACTH secreting adenomas (Cushing's disease and Nelson's syndrome) using the Leksell gamma knife (LGK) irradiation. Twenty-six patients with Cushing's disease were followed-up after LGK irradiation for 48-216 months (median 78 months). Seventeen patients had undergone previous surgery, in nine patients LGK irradiation was the primary therapy. Furthermore, 14 patients with Nelson's syndrome were followed-up for 30-204 months (median 144 months). LGK treatment resulted in hormonal normalization in 80.7 % of patients with Cushing's disease. Time to normalization was 6-54 months (median 30 months). The volume of the adenoma decreased in 92.3% (in 30.7% disappeared completely). There was no recurrence of the disease. In all 14 patients with Nelson's syndrome ACTH levels decreased (in two patients fully normalized) their ACTH levels. When checked up 5-10 years after irradiation regrowth of the adenoma was only detected in one patient (9.1%), in 27.3% adenoma volume remained unchanged, in 45.4% adenoma volume decreased and in 18.2% adenoma completely disappeared. Hypopituitarism did not develop in any patient where the critical dose to the pituitary and distal infundibulum was respected. LGK radiation represents an effective and well-tolerated option for the treatment of patients with Cushing's disease after unsuccessful surgery and may be valuable even as a primary treatment in patients who are not suitable for, or refuse, surgery. In the case of Nelson's syndrome it is possible to impede tumorous growth and control the size of the adenoma in almost all patients.

Estuaries along the north side of the Alaska Peninsula provide essential habitat for most of the American population of Emperor Goose (Chen canagica) during migration (Petersen and Gill 1982). Most of the population passes through Nelson Lagoon in spring and fall, with over 40,000 birds recorded there (Gill et al 1981). Little is known about the feeding activity of Emperor Geese while they are in estuaries, and the importance of estuaries as staging areas during spring and fall migration is poorly understood. Here I report observations on the feeding activity of emperor Geese at one estuary (Nelson Lagoon).

Full Text Available This study applied the hedonic pricing method to determine whether a disused, solid waste landfill site has an adverse effect on the prices of low-cost houses in New Brighton, a neighbourhood of the Nelson Mandela Metropole, Eastern Cape, South Africa. The results of the study show that the landfill site has a negative effect on New Brighton house prices. The average increase in house value is R36.00 per one hundred metres from the landfill site. This increase amounts to 0.44 percent of the value of a house per 100 metres from the landfill. When the change in value is summed for all the properties in the sample area (allowing for variation in value change due to differing distances from the landfill site the total disamenity effect of the landfill site is approximately R1.4 million.

The Pediatric Cardiac Centre for Africa (PCCA) was opened by national patron Mr Nelson Mandela on November 7, 2003. In 2008, the Centre's international pediatric cardiac symposium was introduced as a learning forum for pediatric cardiac surgeons and cardiologists in the continent. The symposium has consistently grown in attendance and attracted distinguished leaders in the field. The 2012 symposium featured Dr. Thomas Spray of Children's Hospital of Philadelphia, Dr. David Barron of Birmingham Children's Hospital, and Dr. John Brown of Indiana University School of Medicine as guest speakers. Experience of the Fontan procedure, the small aortic root, hypoplastic left heart syndrome, right ventricular outflow tract reconstruction, transposition of the great arteries, and interrupted aortic arch were the highlights of the symposium. In the "African Corner," centers in South Africa, Ghana, and Angola presented work done from across the African continent.

Ruxwana, Nkqubela L; Herselman, Marlien E; Conradie, D Pieter

Information and Communication Technology (ICT) solutions (e.g. e-health, telemedicine, e-education) are often viewed as vehicles to bridge the digital divide between rural and urban healthcare centres and to resolve shortcomings in the rural health sector. This study focused on factors perceived to influence the uptake and use of ICTs as e-health solutions in selected rural Eastern Cape healthcare centres, and on structural variables relating to these facilities and processes. Attention was also given to two psychological variables that may underlie an individual&s acceptance and use of ICTs: usefulness and ease of use. Recommendations are made with regard to how ICTs can be used more effectively to improve health systems at fi ve rural healthcare centres where questionnaire and interview data were collected: St. Lucy&s Hospital, Nessie Knight Hospital, the Tsilitwa Clinic, the Madzikane Ka-Zulu Memorial Hospital and the Nelson Mandela General Hospital.

Mandela’s Favourite African Folktales

Directory of Open Access Journals (Sweden)

Carmen Concilio

2014-11-01

Full Text Available In this essay I would like to examine the selection of African tales that Nelson Mandela took care to leave as heritage to the future generations, not only to children, and not only to African children. The fact that a political leader, ex freedom fighter and political prisoner dedicated his time to the collection and editing of stories from all over the African continent to be addressed to new readers as simple entertainment or as educational tools clearly testifies to the great humanity, culture, and open mindedness of one of the most important men of our times. In his most recent autobiographical writing Conversations With Myself, Mandela claimed his double affiliation to both his own indigenous culture as well as to western culture. Moreover, he recalled with affection a dear pastime of his childhood: After supper we would listen enthralled to my mother and sometimes my aunt telling us stories, legends, myths and fables which have come down from countless generations, and all of which tended to stimulate the imagination and contained some valuable moral lesson. (p. 10 Thus, it is not surprising that such a charismatic public figure, as Mandela has been, was also interested in- and worried about- the future survival of a cluster of traditional folktales with their lively, specific and “valuable moral lesson”. It is my intention to verify if there might be a dialogue between the western tradition of folktales where animals are protagonists and speak as anthropomorphic figures and the facets of the African traditions and cultures from which Mandela draws inspiration. Among the critical tools on this topic, Tess Cosslett’s Talking Animals in British Children’s Fiction (2006 seems to provide a useful starting point, together with the latest studies in the volume Dall’ABC a Harry Potter (2011, among others. Moreover, aspects of “orature” will be discussed with reference to the stories chosen by Nelson Mandela. Finally, an attempt

To determine the magnitude, socio-demographic and epidemiological characteristics of injury at a Provincial referral hospital. This review was conducted on all trauma patients admitted at the Mthatha Hospital Complex and Nelson Mandela Academic Hospital from the 1(st) January 1997 to the 31(st) December 2000. The incident rate of injuries was 3.2% (n=2460/75,833 total admissions). Injured patients were mostly black (80%) and males (ratio: 5 men: 1 woman). Only 8.1% of injured patients were transported to hospital by ambulances. The leading causes of injuries were inter-personal violence accounting for 60% of cases, and motor vehicle accidents accounting for 19%; of them 38% were due to poor visibility, over speeding, and fatigue. The overall mortality was 33% (n=821) independently predicted by poverty (OR=8.2 95%CI 6-11.1; P40 years(OR=7.8 95%CI 7.7-12.1;P<0.0001). The burden of injury is a mass issue that warrants regional attention with quality of care and training.

Twenty-three studies (43.4% received provisional approval on the first response, 2 proposals (3.8% were rejected, and 28 proposals (52.8% were sent back with major queries. For the 28 proposals that required major revisions, 11 responses had been submitted by the time the data were collected. The average length of time to receive a response from the applicants to BREC queries was 4 weeks.Conclusion. This study suggests that there is a potential cumulative delay of over 4 months before data collection for low-risk clinical audits can be commenced. Any system designed to improve this situation must ensure that high standards of vigilance are maintained, but must be flexible enough to allow for a faster review and approval process.

Mercury in Nelson's Sparrow subspecies at breeding sites.

Directory of Open Access Journals (Sweden)

Virginia L Winder

Full Text Available BACKGROUND: Mercury is a persistent, biomagnifying contaminant that can cause negative effects on ecosystems. Marshes are often areas of relatively high mercury methylation and bioaccumulation. Nelson's Sparrows (Ammodramus nelsoni use marsh habitats year-round and have been documented to exhibit tissue mercury concentrations that exceed negative effects thresholds. We sought to further characterize the potential risk of Nelson's Sparrows to mercury exposure by sampling individuals from sites within the range of each of its subspecies. METHODOLOGY/PRINCIPAL FINDINGS: From 2009 to 2011, we captured adult Nelson's Sparrows at sites within the breeding range of each subspecies (A. n. nelsoni: Grand Forks and Upham, North Dakota; A. n. alterus: Moosonee, Ontario; and A. n. subvirgatus: Grand Manan Island, New Brunswick and sampled breast feathers, the first primary feather (P1, and blood for total mercury analysis. Mean blood mercury in nelsoni individuals captured near Grand Forks ranged from 0.84 ± 0.37 to 1.65 ± 1.02 SD ppm among years, between 2.0 and 4.9 times as high as concentrations at the other sites (P<0.01. Breast feather mercury did not vary among sites within a given sampling year (site means ranged from 0.98 ± 0.69 to 2.71 ± 2.93 ppm. Mean P1 mercury in alterus (2.96 ± 1.84 ppm fw was significantly lower than in any other sampled population (5.25 ± 2.24-6.77 ± 3.51 ppm; P ≤ 0.03. CONCLUSIONS/SIGNIFICANCE: Our study further characterized mercury in Nelson's Sparrows near Grand Forks; we documented localized and potentially harmful mercury concentrations, indicating that this area may represent a biological mercury hotspot. This finding warrants further research to determine if wildlife populations of conservation or recreational interest in this area may be experiencing negative effects due to mercury exposure. We present preliminary conclusions about the risk of each sampled population to mercury exposure.

History, memory and reconciliation: Njabulo Ndebele’s The cry of Winnie Mandela and Pumla Gobodo-Madikizela’s A human being died that night

Directory of Open Access Journals (Sweden)

R. Goodman

2006-07-01

Full Text Available This article deals with two texts written during the process of transition in South Africa, using them to explore the cultural and ethical complexity of that process. Both Njabulo Ndebele’s “The cry of Winnie Mandela” and Pumla Gobodo-Madikizela’s “A human being died that night” deal with controversial public figures, Winnie Mandela and Eugene de Kock respectively, whose role in South African history has made them part of the national iconography. Ndebele and Gobodo-Madikizela employ narrative techniques that expose and exploit faultlines in the popular representations of these figures. The two texts offer radical ways of understanding the communal and individual suffering caused by apartheid, challenging readers to respond to the past in ways that will promote healing rather than perpetuate a spirit of revenge. The part played by official histories is implicitly questioned and the role of individual stories is shown to be crucial. Forgiveness and reconciliation are seen as dependent on an awareness of the complex circumstances and the humanity of those who are labelled as offenders. This requirement applies especially to the case of “A human being died that night”, a text that insists that the overt acknowledgement of the humanity of people like Eugene de Kock is an important way of healing South African society.

Highlights: • Comparisons between actual measured and simulated performance of a grid-connected PV system. • Simulation using measured climate data sets gave good monthly energy yield comparisons to the measured. • The measured performance ratio of 84.3% shows vast solar energy potential in Eastern Cape region of South Africa. • Better annual specific yield is observed in this study compared to other studies internationally. - Abstract: This paper analyzes and compares the actual measured and simulated performance of a 3.2 kWp grid-connected photovoltaic system. The system is located at the Outdoor Research Facility (34.01°S, 25.67°E) at the Nelson Mandela Metropolitan University (NMMU), South Africa. The system consists of 14 poly crystalline silicon modules connected in two strings of 7 series-connected modules, each facing north at a fixed tilt of 34°. The data presented in this study were measured in the year 2013, where the system supplied a total of 5757 kW h to the local electric utility grid. The performance of the system was simulated using PVsyst software using measured and Meteonorm derived climate data sets (solar radiation, ambient temperature and wind speed). The comparison between measured and simulated energy yield are discussed. Although, both simulation results were similar, better comparison between measured and predicted monthly energy yield is observed with simulation performed using measured weather data at the site. The measured performance ratio in the present study is 84% which is slightly higher than values of 74%, 81.5%, 67.4%, 70% and 64.5% reported is Khatkar-Kalan (India), Dublin (Ireland), Crete (Greece), Karnataka (India) and Malaga (Spain), respectively

Aim: Therefore, the primary objective of this research was to investigate the factors that influence women’s perceived successful investment planning in the Nelson Mandela Bay area. After conducting a comprehensive literature study, six factors (independent variables, namely, values, attitudes, time horizon, personal life cycle, risks and returns, and investment knowledge, were identified as influencing the perceived successful investment planning (dependent variable of women. Setting: As this study focussed on the perceptions of women concerning the factors that influence successful investment planning, the target population was all women in the Nelson Mandela Bay area older than 20 years with some investment experience. Methods: A quantitative research methodology was followed, and data were collected from 207 women using a structured self-administered questionnaire. Results: The results of the multiple regression analysis revealed that only one independent variable emerged as having a significant influence on perceived successful investment planning of women, namely, investment knowledge. Conclusion: Based on the empirical results of this study, several recommendations have been made in an attempt to assist women to make more informed investment decisions and manage their investment planning more effectively as they progress through life.

Islet immunity and beta cell reserve status were utilized to classify persons with ketoacidosis as the initial manifestation of diabetes. The clinical features of the various diabetes classes were also characterized. Prospective cross sectional study. Nelson Mandela Academic Hospital, Mthatha, Eastern Cape Province, South Africa. Indigenous Black South Africans with ketoacidosis as the initial manifestation of diabetes. Islet immunity and beta cell reserve were respectively assessed using serum anti-glutamic acid decarboxylase 65 (GAD) antibody and serum C-peptide after 1 mg of intravenous glucagon. Serum anti-GAD 65 antibody > or = 5 units/L and or = 0.5 ng/mL and < 0.5 ng/mL, respectively. The proportions of patients with A+beta-, A+beta+, A-beta- and A-beta+ and their clinical characteristics were determined. Of the 38 males and 33 females who participated in the study, patients were categorized in various classes: A-beta+, 46.5% (n=33/ 71); A-beta-, 26.8% (n=19/71); A+beta-, 22.5% (n=16/71); and A+beta+, 4.2% (n=3/71). The ages of the various classes were: 41.8 +/- 13.8 years for A-beta+ (n=33); 36.5 +/- 14.6 years for A-beta- (n=19); and 20.6 +/- 7.1 years for the combination of A+beta- with A+beta+ (n=19) (P<.0001, P<.0001 for the combination of A+beta- and A+beta+ vs A-beta+, P=.001 for the combination of A+beta- and A+beta+ vs A-beta-and P=.2 for A-beta- vs A-beta+. The clinical features of type 2 diabetes were most prevalent in A-beta+ class while the A+beta- and A+beta+ groups had the clinical profile of type 1A diabetes. Most of the indigenous Black South African patients with ketoacidosis as the initial manifestation of diabetes had islet immunity, beta cell reserve status and clinical profiles of type 2 diabetes.

The therapeutic considerations in the management of Nelson's syndrome in a 29 year old primigravida are described. CT scans revealed a 2-cm solid pituitary lesion with suprasellar extension and chiasmatic encroachment. A transsphenoidal hypophysectomy was performed to remove a eosinophilic pituitary adenoma. The patient's symptoms improved following surgery. Fetal growth was followed by ultrasound and a female infant was delivered by cesarean section. Follow-up CT scan 2 weeks after delivery revealed no evidence of tumor recurrence.

A continuous high-resolution record of western South Island environmental change over the last 31,000 years from stable isotope analyses of two north-west Nelson speleothems

Core samples were taken through large sheets of calcite flowstone growing in two cave systems, Nettlebed, and Exhaleair, in north-west Nelson, New Zealand. The sampled flowstones are at elevations of 400 m asl and 600 m asl, and are both located 200m below the surface. Ten high-precision U-series dates, measured by thermal ionisation mass spectroemtry, indicate the Nettlebed flowstone grew continuously over the last 31 ka. The Exhaleair flowstone grew continuously over the last 16 ka, following a 50 ka hiatus in deposition. The speleothems from both caves show similar records of oxygen isotope variation over the last 16 ka. The carbon isotope record from Nettlebed shows considerable variation, of almost 10 per thousand from the last glacial maximum to the early Holocene. It is anticipated that these well-dated speleothem records will enable more accurate constraints to be placed on the timing of glacial advances and vegetation changes in the western South Island than are possible using the available radiocarbon ages alone.

Let ψ t , ψ t n , n≥1, be solutions of Schroedinger equations with potentials form-bounded by -1/2 Δ and initial data in H 1 (R d ). Let P, P n , n≥1, be the probability measures on the path space Ω=C(R + , R d ) given by the corresponding Nelson diffusions. We show that if {ψ t n } n≥1 converges to ψ t in H 2 (R d ), uniformly in t over compact intervals, then {P n } n≥1 converges to P in total variation. Moreover, if the potentials are in the Kato class K d , we show that the above result follows from H 1 -convergence of initial data, and K d -convergence of potentials. (orig.)

Full Text Available For 300 years,. the name of Sheikh Yusuf, son of Macassar was missing from the government's attention and public intellectual as well. But when Nelson Mandela, President of South Africa,. commemorated 300 years of the arrival of Sheikh Yusuf in Cape Town in 1994, since that time government institution civil society and academics from Indonesia and South Africa have been paying to attention to remember, understand and study him from various perspectives. By using concept of remembering and forgetting, this article shows that the process of remembering by the two countries did not take place in the empty space, but rely on psychological consideration of the individuals, communities and socio-political condition from the two countries. The process of forgetting constructed by the Dutch colonial state in 17th century became inversely proportional to the action of remembering the Sheikh Yusuf by African and Indonesian officials in 20th century. The proces of remembering shows its own dynamics ranging from individuals communities to public memory. When remembering Syekh Yusuf reached state memory or public memory it became a power that can define and plan a socio-political and economic agenda for the future by the countries.

The article argues that moral leadership by the Christian faith community in South Africa which combats violence by rising up in compassion against injustice can counter-balance the spiralling out of retaliation through revenge. The article describes tolerance in terms of the Pauline concept of endurance and the internalisation of hope for the future. Perseverance despite suffering is seen as the contents of tolerance in the midst of aggressive opposition against the essence of life experienced in terms of an individual�s thinking, willing and feeling. The article is a reworked version of a bilingual commemorative public lecture in English and Afrikaans presented on the occasion of the University of Pretoria�s centenary celebration and is dedicated to Professor Dr P J G Meiring, a member of the Commission of Peace and Reconciliation in South Africa.

To determine whether implementation of provider-initiated human immunodeficiency virus (HIV) counseling would increase the proportion of tuberculosis (TB) patients who received HIV counseling and testing. Cluster-randomized trial with clinic as the unit of randomization. Twenty, medium-sized primary care TB clinics in the Nelson Mandela Metropolitan Municipality, Port Elizabeth, Eastern Cape Province, South Africa. A total of 754 adults (18 years and older) newly registered as TB patients in the 20 study clinics. Implementation of provider-initiated HIV counseling and testing. Percentage of TB patients HIV counseled and tested. SECONDARY: Percentage of patients with HIV test positive, and percentage of those who received cotrimoxazole and who were referred for HIV care. : A total of 754 adults newly registered as TB patients were enrolled. In clinics randomly assigned to implement provider-initiated HIV counseling and testing, 20.7% (73/352) patients were counseled versus 7.7% (31/402) in the control clinics (P = 0.011), and 20.2% (n = 71) versus 6.5% (n = 26) underwent HIV testing (P = 0.009). Of those patients counseled, 97% in the intervention clinics accepted testing versus 79% in control clinics (P = 0.12). The proportion of patients identified as HIV infected in intervention clinics was 8.5% versus 2.5% in control clinics (P = 0.044). Fewer than 40% of patients with a positive HIV test were prescribed cotrimoxazole or referred for HIV care in either study arm. Provider-initiated HIV counseling significantly increased the proportion of adult TB patients who received HIV counseling and testing, but the magnitude of the effect was small. Additional interventions to optimize HIV testing for TB patients urgently need to be evaluated.

The prevalence of HIV&AIDS is embedded in social and economic inequity and the relationship between social determinants and HIV incidence is well established. The aim of this study was to determine which socio-economic and demographic factors are related to HIV status in the age group 18 to 49 years in informal settlements in the Eastern Cape, South Africa. This cross-sectional study was conducted in 3 informal settlements (n = 752) during March 2013 within the Nelson Mandela Bay and Buffalo City districts. A proportional cluster sample was selected and stratified by area and formal plot/squatter households in open areas. Respondents who volunteered to participate had to provide informed written consent before trained, bilingual peer educators interviewed them and completed the structured questionnaire. HIV status was determined and information on demographic and socio-economic variables was included in the bivariate analysis. The prevalence of HIV was higher, at 17.3%, than the 2011 estimated national prevalence among the general population in South Africa. The level of education (χ(2) = 5.50, df = 1, p < 0.05), geographical site (χ(2) = 7.41, df = 2, p < 0.05), gender (χ(2) = 33.10, df = 1, p < 0.0005), household food insecurity (χ(2) = 4.77, df = 1, p < 0.05), cooking with cast iron pots (χ(2) = 15.0, df = 3, p < 0.05) and availability of perceived 'wealth' indicators like mobile telephones and refrigerators (χ(2) = 9.67, df = 2, p < 0.05) were significantly associated with HIV-status. No significant associations could be demonstrated between household income, the number of people living in the household and the availability of electricity/water and HIV status. As the observed levels of HIV prevalence underlined gender bias and failure to graduate from high school, future interventions should focus on HIV prevention in female schoolchildren. However, HIV infection is also prevalent among wealthier individuals in informal settlements, which indicates that

Special article: Horace Nelson MD, John Webster LDS--unrecognized Canadian anesthesia pioneers.

The timing of the earliest reported ether anesthetics in early 1847, in regions to become Canada in July 1867, was examined using information from on-line and library-based sources. Previous authors had identified the first reported ether anesthetic given by a visiting American dentist in January 1847 in Saint John, New Brunswick. Nevertheless, they had reported three different anesthetics as the second occurrence - which would denote the first anesthetic given by a resident of Canada. We confirmed that there were no reports of ether anesthetics being given in Canada before that reported on January 18, 1847 in Saint John. The information available for our review indicates that the second ether anesthetic, and the first by a Canadian, was given in Montreal by a dentist, Dr. John Horatio Webster, on February 20, 1847. The surgical assistant for that operation, Dr. Horace Nelson, later reported on animal and human experiments with ether, which he had led in Montreal starting in January 1847. Earlier authors, who may not have had access to the information now available, came to incorrect conclusions about the first ether anesthetic reported to have been given by a Canadian. Current information indicates that John Webster gave the first reported anesthetic in Montreal on February 20, 1847 following experiments with ether led by Horace Nelson. Both Webster and Nelson deserve recognition as Canadian anesthesia pioneers.

Preliminary report on the Nelson and Radovan copper prospects, Nizina district, Alaska

Renewed copper exploration by Alaska Copper Mines, Incorporated, at the Nelson and Radovan prospects, Nizina district, Alaska, led the Geological Survey in 1951 to map in detail the Nelson fault block, and to re-examine the old workings. In addition, two new prospects were studied. The Nelson fault block is cut by many dominantly strike-slip faults of small displacement, and by bedding faults. Slickensided chalcocite shows post-mineral movement, and chalcocite veinlet in a filled solution cavity indicates that some of the chalcocite is secondary, perhaps very recent. Structural relations indicate two overthrust faults cut the block. The Radovan Greenstone prospect shows massive chalcocite, up to 3 feet wide, in a silicified, epidotized fault zone in the Nikolai greenstone. Ore indicated by surface exposures may amount to 450 tons of chalcocite. The Radovan Low-Contact prospect is on a continuation of the same fault approximately 3 miles southwest of the Greenstone prospect, and 150 feet above the contact of the Nikolai greenstone and the overlying Chitistone limestone. Limonite staining is widespread in bedding planes and small faults near the fault zone; mineralization in the fault zone consists of pyrite, chalcocite, bornite, malachite, realgar, orpiment and stibnite. The sulphides in the fault zone, plus the widespread silicification and epidotization indicate a strong zone of hydrothermal activity which merits extensive prospecting.

The Validity of Likeability as a New Construct of ESL Pronunciation

Directory of Open Access Journals (Sweden)

Hmoud Alotaibi

2014-06-01

Full Text Available The most significant constructs of ESL pronunciation models are accentedness, intelligibility, and comprehensibility (Derwing & Munro 2005; Jenkins, 2000; Pickering, 2006. It is clear though that the assessment of these characteristics shows no consideration for the potential affection of the assessor towards the speaker. Thus, the study presented here proposes a notion named “likeability” (L to examine whether the ratings of listeners are determined in part by the esteem in which they hold the speaker. A questionnaire compiled by Murphy (2014 was given to 11 US and 11 ELLs. Participants were provided with three YouTube links of interviews of Nelson Mandela, a former President of South Africa, Ban Ki-Moon, the current Secretary-General of the United Nations, and Bandar Bin Sultan, the former Saudi ambassador to the United States. The first hypothesis of the study is that the American raters would be harsher in their judgments of Ban Ki-moon and Bin Sultan due to the political conflict and the dramatic events that have been associated with them in the past but this would not be the case with Mandela who has many ardent admirers in the U.S.A. The second hypothesis is that the participants among the international group who share the language background of the speaker would rate that speaker more highly than the others. Unexpectedly, however, both US and ELL listeners rated Mandela the lowest in terms of comprehensibility and Bin Sultan the most comprehensible. All the participants in the international group provided similar ratings regardless of whether they share the language background of the speaker or not. The paper concludes with a suggestion for more thorough investigation of the concept of likeability in selecting ESL speech models, particularly with assigning speakers with different professional fields, ethnicity, and language background. This investigation is crucial in finding the most suitable models for pronunciation teaching.

Mixing and photoreactivity of dissolved organic matter in the Nelson/Hayes estuarine system (Hudson Bay, Canada)

2016-09-01

This work presents the results of a 4-year study (2009-2012) investigating the mixing and photoreactivity of dissolved organic matter (DOM) in the Nelson/Hayes estuary (Hudson Bay). Dissolved organic carbon (DOC), colored DOM, and humic-like DOM decreased with increasing salinity (r2 = 0.70-0.84). Removal of DOM was noticeable at low to mid salinity range, likely due to degradation and/or adsorption to particles. DOM photobleaching rates (i.e., decrease in DOM signal resulting from exposure to solar radiation) ranged from 0.005 to 0.030 h- 1, corresponding to half-lives of 4.9-9.9 days. Dissolved organic matter from the Nelson and Hayes Rivers was more photoreactive than from the estuary where the photodegradation of terrestrial DOM decreased with increasing salinity. Coincident with the loss of CDOM absorption was an increase in spectral slope S, suggesting a decrease in DOM molecular weight. Marked differences in photoreactivity of protein- and humic-like DOM were observed with highly humidified material being the most photosensitive. Information generated by our study will provide a valuable data set for better understanding the impacts of future hydroelectric development and climate change on DOM biogeochemical dynamics in the Nelson/Hayes estuary and coastal domain. This study will constitute a reference on terrestrial DOM fate prior to building additional generating capacity on the Nelson River.

A generalization of Fenyes-Nelson stochastic model of quantum mechanics

1979-01-01

It is shown that the stochastic model of Fenyes and Nelson can be generalized in such a way that the diffusion constant of the Markov theory becomes a free parameter. This extra freedom allows one to identify quantum mechanics with a class of Markov processes with diffusion constants varying from 0 to infinity. (Auth.)

Traditional herbal medicines: potential degradation of sterols and sterolins by microbial contaminants

Directory of Open Access Journals (Sweden)

S. Govender

2010-01-01

Full Text Available Medicinal plants with a high content of sterols and sterolins, such as Bulbine natalensis (rooiwortel and Hypoxis hemerocallidea (African potato, are commonly and inappropriately used in South Africa for the treatment of HIV/AIDS due to the inaccessibility of antiretroviral drugs. This study investigated the presence of active compounds, such as sterols and sterolins, in the herbal medicines. The research was carried out in the Nelson Mandela Metropole area. The effect of microbial contaminants isolated from the medicines on sterols and sterolins of rooiwortel extracts was assessed. Sterols and sterolins were detected in rooiwortel, raw African potatoes and one ready-made mixture. Co-incubation of rooiwortel with bacteria (Bacillus spp. and Pseudomonas putida and fungi (Aspergillus spp., Penicillium spp. and Mucor spp. that were isolated from these samples increased the rate of degradation of sterols and sterolins over time, with slower degradation at 4°C than at 28°C.

Crossing lines: the novels of Nadine Gordimer with a particular focus on Occasion for loving and The pickup

Directory of Open Access Journals (Sweden)

D.A. Barker

2007-07-01

Full Text Available Novelist, playwright, short-story writer, polemicist and activist, Nadine Gordimer (1929, received the Nobel Prize for literature in 1991. She is an implacable opponent of apartheid, which she opposed through her imaginative writing as well as through essays and polemics. The end of apartheid was heralded by the release of Nelson Mandela in 1990, and officially ended with the first democratic elections that were held in April of 1994. Gordimer has produced fourteen novels to date: ten falling clearly within the apartheid period, and four novels that can be classified as falling within the postapartheid period. There is evidence of several general and interrelated shifts in her novels since the demise of apartheid. The previous emphasis on the community and communal responsibility has to some extent been replaced by a relatively greater emphasis on the individual, that is, a move from a stress on public identity to private identity. Local, South African concerns are succeeded by more global concerns. This article discusses these developments, with a specific focus on “Occasion for loving” (1963 and “The pickup” (2001.

Extension of Nelson's stochastic quantization to finite temperature using thermo field dynamics

International Nuclear Information System (INIS)

Kobayashi, K.; Yamanaka, Y.

2011-01-01

We present an extension of Nelson's stochastic quantum mechanics to finite temperature. Utilizing the formulation of Thermo Field Dynamics (TFD), we can show that Ito's stochastic equations for tilde and non-tilde particle positions reproduce the TFD-type Schroedinger equation which is equivalent to the Liouville-von Neumann equation. In our formalism, the drift terms in the Ito's stochastic equation have the temperature dependence and the thermal fluctuation is induced through the correlation of the non-tilde and tilde particles. We show that our formalism satisfies the position-momentum uncertainty relation at finite temperature. -- Highlights: → Utilizing TFD, we extend Nelson's stochastic method to finite temperature. → We introduce stochastic equations for tilde and non-tilde particles. → Our stochastic equations can reproduce the TFD-type Schroedinger equation. → Our formalism satisfies the uncertainly relation at finite temperature.

Establishing psychiatric registrars' competence in psychotherapy: a portfolio based model.

Science.gov (United States)

Naidu, T; Ramlall, S

2008-11-01

During most of the latter part of the last century, South Africa has followed international trends in the training of psychiatrists. Training programmes have become increasingly focused on the neurobiological aspects of psychiatric disorders with less attention being paid to psychotherapy. This is consistent with developments in psychiatric research. In the clinical arena this manifests as a focus on pharmacological and medically based interventions and a resulting relative inattention to non-pharmacological interventions, most especially psychotherapy. In an effort to address this imbalance there has been an international initiative, over the past two decades, to establish an acceptable level of competence in psychotherapy in the training of psychiatrists. A South African programme is needed that can take account of international trends and adapt them for the local context. In order to produce a programme for establishing competence in psychotherapy for psychiatric registrars at the Nelson R. Mandela School of Medicine, the authors examine directives for the development of psychotherapy skills from international regulatory bodies for graduate medical training and their application. Defining and setting preliminary standards for competence is emphasized. A programme based on five core psychotherapy components using a portfolio based model to facilitate learning and assessment of competence in psychotherapy, is proposed.

Environmental isotopes in New Zealand hydrology ; 4. Oxygen isotope variations in subsurface waters of the Waimea Plains, Nelson

1981-01-01

Oxygen isotope measurements of ground and surface waters of the Waimea Plains, Nelson, have been used to identify sources of water in aquifers beneath the plains. Major rivers flowing onto the plains are from higher-altitude catchments (maximum altitude 2000 m) and have delta O 18 approximately equal to -7.2%, whereas rainfall on the plains and adjacent low-altitude catchment streams have delta O 18 approximately equal to -6.2%. The delta O 18 measurements indicate that the 3 major aquifer units, the ''Lower Confined Aquifers'' and the ''Upper Confined Aquifers'' in the Hope Gravel (Late Pleistocene) and the ''Unconfined Aquifers'' in the Appleby Gravel (Holocene) are recharged from different sources. The ''Lower Confined Aquifers'' probably receive slow recharge in the south near Brightwater. The ''Upper Confined Aquifers'' are recharged, in the south, from the Wairoa River and locally in the north are connected with the unconfined aquifers. The ''Unconfined Aquifers'' are recharged from the Waimea River and, away from the river, from rainfall. Intermixing of water, via multiple screened wells, between the various aquifers is also indicated. (author). 5 refs., 5 figs., 1 tab

Objective To determine whether implementation of provider-initiated HIV counseling would increase the proportion of tuberculosis patients that received HIV counseling and testing. Design Cluster-randomized trial with clinic as unit of randomization Setting Twenty, medium-sized primary care TB clinics in the Nelson Mandela Metropolitan Municipality, Port Elizabeth, Eastern Cape Province, South Africa Subjects A total of 754 adults (≥ 18 years) newly registered as tuberculosis patients the twenty study clinics Intervention Implementation of provider-initiated HIV counseling and testing. Main outcome measures Percentage of TB patients HIV counseled and tested. Secondary Percentage of patients HIV test positive and percentage of those that received cotrimoxazole and who were referred for HIV care. Results A total of 754 adults newly registered as tuberculosis patients were enrolled. In clinics randomly assigned to implement provider-initiated HIV counseling and testing, 20.7% (73/352) patients were counseled versus 7.7% (31/402) in the control clinics (p = 0.011), and 20.2 % (n = 71) versus 6.5% (n = 26) underwent HIV testing (p = 0.009). Of those patients counseled, 97% in the intervention clinics accepted testing versus 79% in control clinics (p =0.12). The proportion of patients identified as HIV-infected in intervention clinics was 8.5% versus 2.5% in control clinics (p=0.044). Fewer than 40% of patients with a positive HIV test were prescribed cotrimoxazole or referred for HIV care in either study arm. Conclusions Provider-initiated HIV counseling significantly increased the proportion of adult TB patients that received HIV counseling and testing, but the magnitude of the effect was small. Additional interventions to optimize HIV testing for TB patients urgently need to be evaluated. PMID:18520677

Um modelo evolucionário Norte-Sul A North-South evolutionary model

2007-12-01

Full Text Available This work expands the classical Nelson and Winter model of Schumpeterian competition by including two sectors and a North-South dynamics, with a view to analyzing how different institutions and technological regimes affect the processes of convergence and divergence in the international economy. The results suggest that convergence may emerge out of the efforts for imitation in the South when the technological regime is cumulative. But when the regime is science-based, imitation is not enough for a successful catching-up. In this case convergence requires the South to invest in innovation as well. The work also analyses the robustness of the model results using Montecarlo techniques.

Relativism: Protagoras and Nelson Goodman

Directory of Open Access Journals (Sweden)

Esmaeil Saadati Khamseh

2015-12-01

Full Text Available Discussion of the many faces of relativism occupies a highly prominent place in the epistemological literature. Protagoras in ancient Greece and Nelson Goodman in the modern period are two most notable proponent of relativism. In the present article, I discuss and explain relativistic approaches of this two important relativist. I will first briefly define and review some faces of relativism. Then I will discuss and elaborate Protagorean or true-for-me relativism and Goodman’s radical relativism in turn. I will argue that there are crucial difficulties in Protagorean and radical relativism, and that these difficulties, as the realist philosophers insist, make these two faces of relativism be undefensible. No doubt, these two shapes of relativism have paved the way for anti-realism. In the end, it will appear that Goodman’s radical relativism and so the theory of worldmaking, like Protagorean relativism, suffers from a fatal flaw: the flaw of self-refuting.

A report on the fisheries resources of the lower Nelson River and the impacts of hydroelectric development, 1988 data

Fisheries studies on the lower Nelson River (Manitoba) system have had the goals of gaining an understanding of the fisheries resources present, assessing current and potential impacts of hydroelectric developments, and investigating enhancement or mitigative options. In 1988, a resource inventory of McMillan and 12-Mile Creeks was conducted to increase understanding of brook trout stocks in the Limestone River system. Results indicate that both streams contain self-sustaining populations. Baseline data collection in the Conawapa Forebay of the Nelson River was initiated in 1988. Inventories of fish populations were conducted, focusing on lake sturgeon. Three long-term monitoring projects were continued in 1988, investigating the populations of spawning brook trout, larval brook trout, and anadromy in brook trout. Four major tributaries to the Nelson River were classified on the basis of physical and chemical characteristics in an attempt to understand brook trout distribution patterns. Ten sturgeon were captured in Angling Lake in 1988 and fitted with radio tags to assess the importance of the Angling Lake-Angling River system to Nelson River lake sturgeon. To investigate the feasibility of enhancing brook trout populations in the Nelson River system, baskets of eggs were planted in previously identified spawning areas in three creeks in 1988. The eggs developed and hatched only in CN Creek. The potential for rehabilitating the Kettle River brook trout population by transfer of fish from other rivers was also investigated in 1988. Radio-tagged fish remained in the Kettle River-Long Spruce system throughout the life of the tags and appear to have found suitable summer and winter habitat. 60 refs., 76 figs., 38 tabs

Full Text Available BACKGROUND: Nelson's, Saltmarsh, and Seaside Sparrows (Ammodramus nelsoni, A. caudacutus, and A. maritimus, respectively depend on marsh and wetland habitats--ecosystems in which mercury (Hg bioavailability is notoriously high. The purpose of the present study was to address the potential impact of Hg on these species using first primary and breast feathers as non-destructive biomonitoring tools. METHODS AND PRINCIPAL FINDINGS: Feathers were sampled from wintering sparrows in North Carolina salt marshes (2006-2010. Feather Hg data were used in three risk analysis components (1 Threshold Component--examined feather Hg with regard to published negative effects thresholds; (2 Hg Dynamics Component--examined Hg in sparrows captured multiple times; and (3 Capture Frequency and Survival Component--tested for links between Hg and return frequency and survival. Threshold Component analyses indicated that Hg concentrations in 42-77% of sampled individuals (breast feather n = 879; first primary feather n = 663 were within the range associated with decreased reproduction in other avian species. Hg Dynamics Component analyses demonstrated that Hg increased between first and second captures for Nelson's (n = 9 and Seaside Sparrows (n = 23. Capture Frequency and Survival Component analyses detected a negative relationship between Hg and capture frequency in Nelson's Sparrows (n = 315. However, MARK models detected no effect of Hg on apparent survival in any species. CONCLUSION AND SIGNIFICANCE: This study indicates that current Hg exposure places a considerable proportion of each population at risk. In particular, 52% of all sampled Saltmarsh Sparrows exhibited first primary feather Hg concentrations exceeding those associated with a >60% reduction in reproductive success in other species. This study reports evidence for net annual bioaccumulation, indicating an increased risk in older individuals. These data can be used to inform future population

1992-01-01

The hypophyses of 13 patients with Nelson syndrome following bilateral adrenalectomy were examined by MRI and CT. Diffuse enlargement of the hypophysis was demonstrated in 8 patients by CT and in 9 by MRI. Compared with CT, MRI provides better demonstration of tumour development, such as abnormal convexity of the cranial margin of the hypophysis (MRI 4/13, CT 1/13), displacement of the infundibulum (MRI 4/13, CT 0/13) or optic chiasm (MRI 2/13, CT 0/13). MRI also provides diagnostically important differentiation between scar tissue and recurrence of tumour following hypophysectomy (MRI 1/3, CT 0/3) and more accurate demonstration of infiltration of the cavernous sinus (MRI 4/13, CT 2/13). CT is superior only in showing the floor of the sella. MRI is the method of choice for imaging in cases of Nelson syndrome. (orig.) [de

The generalized Fenyes-Nelson model for free scalar field theory

International Nuclear Information System (INIS)

Davidson, M.

1980-01-01

The generalized Fenyes-Nelson model of quantum mechanics is applied to the free scalar field. The resulting Markov field is equivalent to the Euclidean Markov field with the times scaled by a common factor which depends on the diffusion parameter. This result is consistent with Guerra's earlier work on stochastic quantization of scalar fields. It suggests a deep connection between Euclidean field theory and the stochastic interpretation of quantum mechanics. The question of Lorentz covariance is also discussed. (orig.)

Provincial–regional ANC politics in the Northern Cape: corruption or everyday informal practices?

Directory of Open Access Journals (Sweden)

Thina Nzo

2017-04-01

Full Text Available Research over the last decade on local government in South Africa has highlighted that some municipal councils under the political leadership of the Africa National Congress (ANC have shown weak political leadership, coupled with strong patronage systems, rent-seeking and corruption which have had an impact on the institutional functionality of municipalities in South Africa. Although patronage politics have been predominantly used to analyse the dynamics of post-apartheid local government ANC politics and councillor representation, this prevents us from understanding the representational focus of ANC councillors in decision-making processes. This paper offers an ethnographic insight into experiences of ANC councillors and the political complexities involved in council decision-making. Using ethnographic research, this paper will analyse how a political decision by the ANC provincial party, which was supported by the ANC regional party at local level – to erect a statue of Nelson Mandela in one of the municipalities in the Northern Cape – generated tensions amongst ANC councillors who strongly viewed their primary role as promoters of better ‘service delivery’ rather than approving the allocation of scarce municipal resources for erecting a statue. The paper reveals how the dominant presence of ANC sub-regional structures at local level contribute to the complex interaction of both ANC party political and municipal organisational rules and norms that influence and shape councillors’ choices in decision-making.

OpenAIRE

Nyholm, Ken

2015-01-01

A factor rotation scheme is applied to the well-known Dynamic Nelson-Siegel model facilitating direct parametrization of the short rate process. The model-implied term structure of term premia is derived in closed-form, and macroeconomic variables are included in a Taylor-rule- type fashion. Four empirical experiments are performed on US data covering the period from 1990 to 2014. It is found that macroeconomic variables impact the evolution of the short rate until 2002, after which their eff...

The pure phases, the irreducible quantum fields, and dynamical symmetry breaking in Symanzik--Nelson positive quantum field theories

International Nuclear Information System (INIS)

Frohlich, J.

1976-01-01

We prove that a Symanzik--Nelson positive quantum field theory, i.e., a quantum field theory derived from a Euclidean field theory, has a unique decomposition into pure phases which preserves Symanzik--Nelson positivity and Poincare covariance. We derive useful sufficient conditions for the breakdown of an internal symmetry of such a theory in its pure phases, for the self-adjointness and nontrivially (in the sense of Borchers classes) of its quantum fields, and the existence of time-ordered and retarded products. All these general results are then applied to the P (phi) 2 and the phi 3 4 quantum field models

Aim of the present study was to determine syndrome specific mortality rates and the precipitating factors associated with deaths following admission for hyperglycemic crisis to a high care unit. Retrospective review of medical records for hyperglycemic crisis at Nelson Mandela Academic Hospital, Mthatha, Eastern Cape Province of South Africa from February 1 2010 to January 31 2011. All admissions were initially into the high care unit. The overall mortality rates (per admissions) was 13.9% (N.=15/108) with syndrome specific mortality rates (per admissions) of 11.9% (N.=8/67), 0% (N.=0/8) and 21.2% (N.=7/33) respectively for diabetic ketoacidosis (DKA), hyperglycemic hyperosmolar state (HHS) and hyperglycemia with dehydration (HD). The precipitating factors that were mainly associated with mortality were infections and cerebrovascular disease (CVD). The patients with CVD who died were all unconscious. There were no deaths where non-compliance with hypoglycaemic agents (14.8%, N.=16/108) was the precipitating factor. The overall mortality rates (per admissions) following high care unit admissions for hyperglycemic crisis was 13.9% with infections and CVD as the precipitating factors most associated with deaths.

Failure Analysis of Main Flame Deflector Nelson Studs

Science.gov (United States)

Long, Victoria

2009-01-01

NASA Structures engineers submitted two Nelson refractory studs from the main flame deflector at Launch Complex (LC) 39 A for analysis when they were observed to be missing a significant amount of material after launch. The damaged stud and an unused comparative stud were analyzed by macroscopic and microscopic examination along with metallographic evaluation of the microstructure. The stud lost material due to a combination of erosion and corrosion. Plain carbon steel readily forms an oxide layer in the coastal launch environment at Kennedy Space Center. The blast during a launch removes this brittle oxide layer, which then forms again post-launch, thereby further removing material. No indications of melting were observed.

A hermeneutical reading of Penrose and Nelson and Winter-Tracing origins of a misunderstanding?

Directory of Open Access Journals (Sweden)

Dr. Oliver Krone

2010-05-01

Full Text Available This paper aims to understand based on a hermeutical reading of Penrose (1959 and Nelson and Winter (1982 what knowledge is and where it is stored in the respective authors. Furthermore, the author wants to learn whether the subsumtion of Knowledge Integration to Knowledge Management, as it can be often in the literature, has any foundation when coming from these authors. Reason for this overall analysis is the widely held view in the discipline of Knowledge Management that these authors are forefathers for it. Based on an interpretative, qualitative approach the author examines the way in which knowledge is held and created within organisations in the main work of this pair of author. The author comes to the conclusion that the discipline of Knowledge Management has seemingly overemphasised certain elements in the work of Penrose and Nelson and Winter, while neglecting the key aspect that for both author(s the act of Knowledge Integration is much rather described in these works.

Figuring Reconciliation: Dancing With the Enemy

Jane S. Sutton

2007-02-01

Full Text Available This essay is about fi guring “argument as dance” and one way of conceiving how to live or embody argument as such. Concretely, it displays “argument as war” alongside a road in Mississippi after a white man shoots down James Meredith as he asserts his legal right to vote. And it tells “how to” perceive the shooting as dance by turning fi rstly to the performance of dance fi gured in the beginnings of rhetoric and then secondly, setting forth demystifi ed methods and strategies of body-speech fi guring argument as dance, rather than as war, through performances of Nelson Mandela. More generally, it explores a new meaning or experience of rhetoric by explicitly conjoining two historical times, two geographies, two speakers, enemies and dancers, that are inextricably interconnected. Using a combination of description and analysis, the fi rst is a full display of three photographs picturing argument as war. The whole picture serves as a descriptive compass or guide for making our way analytically through argument as war and into dance language and behavior and their interconnections to argument. The second is a retrospective discussion of the background, dancing/argumentative practices, what is called “blinking on the behalf of the enemy,” of Nelson Mandela. Overall, the strategy of reticulating political times, chronology and political spaces, geography on the one hand, and argument as war and argument as dance on the other hand is to reconcile confl icting measures and to produce a performance practice (of rhetoric of which there is no canon.

Hydrology signal from GRACE gravity data in the Nelson River basin, Canada: a comparison of two approaches

Science.gov (United States)

Li, Tanghua; Wu, Patrick; Wang, Hansheng; Jia, Lulu; Steffen, Holger

2018-03-01

The Gravity Recovery and Climate Experiment (GRACE) satellite mission measures the combined gravity signal of several overlapping processes. A common approach to separate the hydrological signal in previous ice-covered regions is to apply numerical models to simulate the glacial isostatic adjustment (GIA) signals related to the vanished ice load and then remove them from the observed GRACE data. However, the results of this method are strongly affected by the uncertainties of the ice and viscosity models of GIA. To avoid this, Wang et al. (Nat Geosci 6(1):38-42, 2013. https://doi.org/10.1038/NGEO1652; Geodesy Geodyn 6(4):267-273, 2015) followed the theory of Wahr et al. (Geophys Res Lett 22(8):977-980, 1995) and isolated water storage changes from GRACE in North America and Scandinavia with the help of Global Positioning System (GPS) data. Lambert et al. (Postglacial rebound and total water storage variations in the Nelson River drainage basin: a gravity GPS Study, Geological Survey of Canada Open File, 7317, 2013a, Geophys Res Lett 40(23):6118-6122, https://doi.org/10.1002/2013GL057973, 2013b) did a similar study for the Nelson River basin in North America but applying GPS and absolute gravity measurements. However, the results of the two studies in the Nelson River basin differ largely, especially for the magnitude of the hydrology signal which differs about 35%. Through detailed comparison and analysis of the input data, data post-processing techniques, methods and results of these two works, we find that the different GRACE data post-processing techniques may lead to this difference. Also the GRACE input has a larger effect on the hydrology signal amplitude than the GPS input in the Nelson River basin due to the relatively small uplift signal in this region. Meanwhile, the influence of the value of α , which represents the ratio between GIA-induced uplift rate and GIA-induced gravity-rate-of-change (before the correction for surface uplift), is more obvious in

Uniform product formulae with application to the Feynman-Nelson integral for open systems

The product formula for perturbations of propagators by Faris is generalized: we show that one can use arbitrary partitions of a given interval and perform the limit uniformly with respect to the partition norm. The results are applied to express solutions of the Schroedinger equation, in particular for some complex and time-dependent potentials, by means of Nelson-type path integrals. (orig.)

Full Text Available Sweet potato cultivar Cilembu, kind of ‘rancing’ from Cilembu Village, Sumedang, West Java has really sweet taste due to the high content of reducing sugar. The amount of reducing sugar needs to be proven scientifically. The study aimed to compare Somogyi-Nelson method and Anthrone-Sulfate method in order to determine reducing sugar level in Cilembu sweet potato. Cilembu sweet potato must be stored in freezer at 15°C for 2 weeks before used as the sample. Analytical method validation was performed for the two methods. The determination results between two methods were compared. The amount of reduction sugar (glucose from Cilembu sweet potato determined by Somogyi-Nelson method was 3.42%, the value of %recovery was 99.8%, LOD = 0.00167 (mg/mL, LOQ = 0.00557 (mg/mL, and value of RSD was 3.7%. While the average amount of reduction sugar determined by Anthrone-Sulfate method was 14.9%, the value of %recovery was 74.7%, LOD = 0.0198 (mg/mL, LOQ = 0.066 (mg/mL, and value of RSD = 8.6%. The Somogyi-Nelson method was more recommended for the analysis of the reducing sugar in Cilembu sweet potato compared with Anthrone-Sulfate method.

Nelson's stochastic quantization of free linearized gravitational field and its Markovian structure

International Nuclear Information System (INIS)

Lim, S.C.

1983-05-01

It is shown that by applying Nelson's stochastic quantization scheme to free linearized gravitational field tensor one can associate with the resulting stochastic system a stochastic tensor field which coincides with the ''space'' part of the Riemannian tensor in Euclidean space-time. However, such a stochastic field fails to satisfy the Markov property. Instead, it satisfies the reflection positivity. The Markovian structure of the stochastic fields associated with the electromagnetic field is also discussed. (author)

2014-11-01

Low-dose CT screening is recommended for individuals at high risk of developing lung cancer. However, CT screening does not detect all lung cancers: some might be missed at screening, and others can develop in the interval between screens. The NELSON trial is a randomised trial to assess the effect of screening with increasing screening intervals on lung cancer mortality. In this prespecified analysis, we aimed to assess screening test performance, and the epidemiological, radiological, and clinical characteristics of interval cancers in NELSON trial participants assigned to the screening group. Eligible participants in the NELSON trial were those aged 50-75 years, who had smoked 15 or more cigarettes per day for more than 25 years or ten or more cigarettes for more than 30 years, and were still smoking or had quit less than 10 years ago. We included all participants assigned to the screening group who had attended at least one round of screening. Screening test results were based on volumetry using a two-step approach. Initially, screening test results were classified as negative, indeterminate, or positive based on nodule presence and volume. Subsequently, participants with an initial indeterminate result underwent follow-up screening to classify their final screening test result as negative or positive, based on nodule volume doubling time. We obtained information about all lung cancer diagnoses made during the first three rounds of screening, plus an additional 2 years of follow-up from the national cancer registry. We determined epidemiological, radiological, participant, and tumour characteristics by reassessing medical files, screening CTs, and clinical CTs. The NELSON trial is registered at www.trialregister.nl, number ISRCTN63545820. 15,822 participants were enrolled in the NELSON trial, of whom 7915 were assigned to low-dose CT screening with increasing interval between screens, and 7907 to no screening. We included 7155 participants in our study, with

Comments on the note by L.S. Nelson: ''unusually high (oxidizer/Pu) ratios in the macro-residues from plutonium droplet combustion''

An alternative explanation for unusually high ratios of oxidizers/plutonium in the residues from plutonium droplet combustion is offered in response to a note by L.S. Nelson. Two additional experiments are suggested that would be helpful in clarifying the high oxidizer/Pu ratios. The first would be to measure the true surface area for a spherule after its explosion. The second is an experiment analogous to a gas analysis experiment. The conclusion is put forth that adsorbed gases are the most likely cause of the high O/M ratios described by Nelson

Representation theory of Lie-admissible enveloping algebras on operator algebras: an extension of a theorem by Nelson

International Nuclear Information System (INIS)

Ghikas, D.K.P.; Ktorides, C.N.; Papaloukas, L.

1980-01-01

This mathematical note is motivated by an assessment concerning our current understanding of the role of Lie-admissible symmetries in connection with quantum structures. We identify the problem of representations of the universal enveloping (lambda, μ)-mutation algebra of a given Lie algebra on a suitable algebra of operators, as constituting a fundamental first step for improving the situation. We acknowledge a number of difficulties which are peculiar to the adopted nonassociative product for the operator algebra. In view of these difficulties, we are presently content in establishing the generalization, to the Lie-admissible case, of a certain theorem by Nelson. This theorem has been very instrumental in Nelson's treatment concerning the Lie symmetry content of quantum structures. It is hoped that a similar situation will eventually prevail for the Lie-admissible case. We offer a number of relevant suggestions

On the Reconciliation of the Extended Nelson-Siegel and the Extended Vasicek Models (with a View Towards Swap and Swaption Valuation)

DEFF Research Database (Denmark)

Jørgensen, Peter Løchte

Extended Nelson-Siegel models are widely used by e.g. practitioners and central banks to estimate current term structures of riskless zero-coupon interest rates, whereas other models such as the extended Vasicek model (a.k.a. the Hull-White model) are popular for pricing interest rate derivatives....... This paper establishes theoretical consistency between these two types of models by showing how to specify the extended Vasicek model such that its implied initial term structure curve precisely matches a given extended Nelson-Siegel specification. That is, we show how to reconcile the two classes of models...

Modeling of Chromium (III) Removal from Heavy Metals Mixture Solutions in Continuous Flow Systems: A Comparative Study between BDST and Yoon -Nelson Models

International Nuclear Information System (INIS)

Ahmed, A.Z.

2011-01-01

The aim of this work is to study modeling of chromium (III) removal from aqueous solution using activated carbon as adsorbent. Studies have been conducted in a continuous fixed bed packed column under different operating conditions such as bed height, flow rate, fluid velocity and fixed adsorbent particle size. The Yoon Nelson model was applied to experimental data to predict the breakthrough curves by calculating the rate constant k and 50 % breakthrough time, θ. The Bed Depth Service Time (BDST) was applied to determine BDST constant K and the capacity of adsorbent, No. Results obtained from both models are compared with the experimental breakthrough curves and a satisfactory agreement was noticed. Therefore, the Yoon - Nelson and BDST models were found suitable for determining the parameters of the column design. The Y 000 - Nelson model was found more accurate in representing the system in comparison with the BDST model although it is less complicated than other models

The morphological characteristics of the humeral bone has been investigated in recent times with studies showing varying degrees of sexual dimorphism. Osteologists and forensic scientists have shown that sex determination methods based on skeletal measurements are population specific, and these population-specific variations are present in many body dimensions. The present study aims to establish sex identification using osteometric standards for the humerus in a contemporary KwaZulu-Natal population. A total of 11 parameters were measured in a sample of n=211 humeri (males, 113; females, 98) from the osteological collection in the Discipline of Clinical Anatomy, Nelson R. Mandela School of Medicine, University of KwaZulu-Natal, Durban, South Africa. The difference in means for nearly all variables were found to be significantly higher in males compared to females ( P <0.01) with the most effective single parameter for predicting sex being the vertical head diameter having an accuracy of 82.5%. Stepwise discriminant analysis increased the overall accuracy rate to 87.7% when all measurements were jointly applied. We conclude that the humerus is an important bone which can be reliably used for sex determination based on standard metric methods despite minor tribal or ancestral differences amongst an otherwise homogenous population.

Late Quaternary pollen records from the Lower Cobb Valley and adjacent areas, north-west Nelson, New Zealand

International Nuclear Information System (INIS)

Shulmeister, J.; McLea, W.L.; Singer, C.; McKay, R.M.; Hosie, C.

2003-01-01

Ten pollen records from the Cobb Valley and adjacent areas in North-West Nelson are described. Collectively they provide a vegetation record extending from the Last Glacial Maximum to the present day. During the Last Glacial Maximum the uplands of North-West Nelson were glaciated. By about 17,000 radiocarbon years BP ice had retreated some distance up the Cobb River Valley and a podocarp heath and tussockland vegetation covered non-glaciated areas. By 14,000 radiocarbon years BP, the valley floor and adjacent lower ridges were occupied by montane podocarp forest dominated by Phyllocladus and Halocarpus. Beech forest expanded into some sites as early as 13,000 yr BP but the modern beech cover was not established until the Holocene. Forest cover has fluctuated in response to disturbance over the Holocene, but the most significant recent change, which is related to clearing for pastoralism in the last two centuries, has had surprisingly little impact on the pollen records.

Nelson's syndrome is a unique clinical phenomenon of growth of a pituitary adenoma following bilateral adrenalectomies for the control of Cushing's disease. Primary management is surgical, with limited effective medical therapies available. We report our own institution's series of this pathology managed with radiation: prior to 1990, 12 patients were managed with conventional radiotherapy, and between 1990 and 2007, five patients underwent stereotactic radiosurgery (SRS) and two patients fractionated stereotactic radiotherapy (FSRT), both using the linear accelerator (LINAC). Tumour control was equivocal, with two of the five SRS patients having a reduction in tumour volume, one patient remaining unchanged, and two patients having an increase in volume. In the FSRT group, one patient had a decrease in tumour volume whilst the other had an increase in volume. Treatment related morbidity was low. Nelson's syndrome is a challenging clinical scenario, with a highly variable response to radiation in our series. Copyright © 2014 Elsevier Ltd. All rights reserved.

The influence of bank employees on bank customer relationship management

Directory of Open Access Journals (Sweden)

C. Rootman

2007-12-01

Full Text Available Purpose: Despite extensive research in services marketing, much is still unknown to specific service providers on the influence of their employees on their services. This paper attempts to address this limitation and investigates the influence of employees on the customer relationship management (CRM of banks. The primary objective of this paper is to investigate the influence of selected independent variables, namely attitude and knowledgeability, on the CRM of banks. Design/Methodology/Approach: An empirical investigation was conducted with a structured questionnaire with items that related to banks' CRM in terms of attitude and knowledgeability. The sample consisted of 290 banking clients in the Nelson Mandela Metropolitan area and the response rate was 91.03%. Findings: Significant positive relationships exist between both the knowledgeability, and attitude of bank employees and a bank's CRM. These relationships imply that more extensive knowledgeability and more positive attitudes of bank employees lead to improved, maintained relationships between a bank and its clients. Employees play an important role in banks’ client relationships. Implications: Banks should focus on increasing their employees' knowledgeability and improving their attitude to ensure higher levels of CRM. This paper provides strategies for banks and could create greater awareness among South African banks of the advantages of CRM, how their employees influence their CRM, and ways to adapt to these influences. Originality/Value: No study has focused exclusively on CRM within banks in South Africa. Prior research focused on customer service and service quality; both possible results of superior CRM. However, this research differs, as it identifies the variables influencing CRM in banks in South Africa. It is proposed that this paper will be beneficial for South African banks, as the recommendations may be used to ensure higher levels of CRM in banks.

Temperature dependences of I-V characteristics and voltage harmonics V n (T) (n = 2, 3, ...) have been investigated in magnetic fields up to 200 Oe for single crystals YBa 2 Cu 3 O 7-x . It was shown that V n (T) had asymmetric peak form with maximum at T* = 92.0 K. Amplitudes of V n (T) were decreased in magnetic fields. The results were explained on the base of the Berezinskii-Kosterlitz-Thouless (BKT) transition model. It was shown that T* coincided with the BKT transition temperature T BKT . The asymmetric peaks of V n (T) are a consequence of the Nelson-Kosterlitz jump

A summary is presented of discussions and conclusions at a workshop held to examine the potential effects of hydroelectric development on beluga whales of the Nelson River estuary in Manitoba. Background information is provided on the estuary, beluga whales and their use of arctic and subarctic estuaries, and hydroelectric development on the Nelson River. Potential impacts of such development on the whales are reviewed in the categories of direct effects of changes in physical-chemical conditions (temperature and discharge), indirect effects of disturbances mediated through the food chain, and effects on socioeconomic conditions that may affect beluga whales. Since the biology of beluga whales and other phenomena of interest in this study are poorly known, recommendations are made for research and monitoring activities in the Nelson River estuary. In general, the workshop participants felt that changes in the estuary due to hydroelectric development would not be large enough to affect beluga whales strongly. 34 refs., 1 fig

2017-09-01

Advances in diagnostic techniques and perioperative care have greatly improved the outcome of neonatal surgery. Despite this, disparity still exists in the outcome of neonatal surgery between developed and developing countries. We performed a prospective study of neonates admitted and treated due to surgical congenital diseases and other conditions in our hospital from April 2015 to April 2017. There were 19 (28,7%) females and 47 (70,3%) males in this group. It was found that 41 neonates had 7 days after birth or less by a 62% and 25 with more than 7 days by 38%. The Anorectal malformations (ARM) were the most frequent congenital anomaly in 21 patients (47%), followed by Gastroquises with 7 neonates (10,6%), Omphalocele with 8 (12%), and Oesophagus Atresia in 5 neonates (7,5%). Intestinal Malrotation with midgut volvulus, Pyloric Stenoses and Duodenal Atresia in 4 neonates (6,2 % each). Others alterations such as, Ileal Atresia, Strangulated Inguinal Hernia, Limb Gangrene, Necrotizing Enterocolitis, Sacro Coxigeal Theratoma, Megacolon Aganglionic, Colon perforation, Gastric perforation and Hydromethrocolpus accounted in 13 neonates by 19,7% from the total of patients. Ten babies died (15%). We conclude that Anorectal Malformations, Gastroquises and Omphalocele were the most frequent malformations. Considering the mortality is above the average of developed countries this could be improved by increasing the knowledge about the neonatal surgery characteristics among medical doctors and improving the necessary facilities and back up.

Implementing AIDS policy in post-apartheid South Africa.

Schneider, H; Stein, J

2001-03-01

In common with the rest of the Southern African sub-continent. South Africa is currently experiencing a serious HIV epidemic. When it came into power in 1994, the new, Mandela-led government immediately mobilised funds and adopted a far-reaching AIDS Plan for the country. However, the implementation of AIDS policy in the first four years after 1994 has been characterised by a lack of progress and a breakdown of trust and co-operation, both within government and between government and NGOs. This paper outlines the political context which shaped the development of the AIDS Policy, then examines the difficulties of implementing a comprehensive response to AIDS in a country undergoing restructuring at every level. It questions the notion of "inadequate political will" as an explanation for lack of progress. Involvement by politicians has, in fact, been experienced as a double-edged sword in South Africa, with inappropriate, "quick-fix" actions creating conflict and hampering a more longer-term, effective response. The paper also highlights the importance of groupings outside of government in promoting effective policy actions, and the types of leadership required to mobilise a broad range of actors around a common vision. It concludes by emphasising the need to develop approaches to policy implementation rooted in the possibilities and constraints of the local situation, rather than relying on universal blue-prints developed out of context.

Human rights and political transition in South Africa: the case of the Truth and Reconciliation Commission

2013-04-01

Full Text Available This article is dedicated to recounting the main initiative of Nelson Mandela’s government to manage the social resentment inherited from the segregationist regime. I conducted interviews with South African intellectuals committed to the theme of transitional justice and with key personalities who played a critical role in this process. The Truth and Reconciliation Commission is presented as the primary institutional mechanism envisioned for the delicate exercise of redefining social relations inherited from the apartheid regime in South Africa. Its founders declared grandiose political intentions to the detriment of localized more palpable objectives. Thus, there was a marked disparity between the ambitious mandate and the political discourse about the commission, and its actual achievements.

Two 20 W copper indium gallium diselenide photovoltaic modules were subjected to a thorough indoor assessment procedure, followed by outdoor deployment at the Nelson Mandela Metropolitan University as part of an ongoing study. The initial indoor measurement of maximum power output (P MAX ) of one of the modules was considerably higher than the manufacturer's rating (E.E. van Dyk, C. Radue and A.R. Gxasheka, Thin Solid Films 515 (2007) 6196). The modules were deployed on a dual-axis solar tracker and current-voltage characteristics were obtained weekly. In addition to the normal PV parameters of short-circuit current, open-circuit voltage, P MAX , fill factor and efficiency, shunt and series resistances were also monitored. The performances of the two modules are compared and analyzed and the results presented in this paper

Quantum cybernetics: a new perspective for Nelson's stochastic theory, nonlocality, and the Klein-Gordon equation

Science.gov (United States)

Grössing, Gerhard

2002-04-01

The Klein-Gordon equation is shown to be equivalent to coupled partial differential equations for a sub-quantum Brownian movement of a “particle”, which is both passively affected by, and actively affecting, a diffusion process of its generally nonlocal environment. This indicates circularly causal, or “cybernetic”, relationships between “particles” and their surroundings. Moreover, in the relativistic domain, the original stochastic theory of Nelson is shown to hold as a limiting case only, i.e., for a vanishing quantum potential.

The divine clockwork: Bohr's correspondence principle and Nelson's stochastic mechanics for the atomic elliptic state

International Nuclear Information System (INIS)

Durran, Richard; Neate, Andrew; Truman, Aubrey

2008-01-01

We consider the Bohr correspondence limit of the Schroedinger wave function for an atomic elliptic state. We analyze this limit in the context of Nelson's stochastic mechanics, exposing an underlying deterministic dynamical system in which trajectories converge to Keplerian motion on an ellipse. This solves the long standing problem of obtaining Kepler's laws of planetary motion in a quantum mechanical setting. In this quantum mechanical setting, local mild instabilities occur in the Keplerian orbit for eccentricities greater than (1/√(2)) which do not occur classically

Conservative diffusions: a constructive approach to Nelson's stochastic mechanics

International Nuclear Information System (INIS)

Carlen, E.A.

1984-01-01

In Nelson's stochastic mechanics, quantum phenomena are described in terms of diffusions instead of wave functions; this thesis is a study of that description. Concern here is with the possibility of describing, as opposed to explaining, quantum phenomena in terms of diffusions. In this direction, the following questions arise: ''Do the diffusion of stochastic mechanics - which are formally given by stochastic differential equations with extremely singular coefficients - really exist.'' Given that they exist, one can ask, ''Do these diffusions have physically reasonable paths to study the behavior of physical systems.'' These are the questions treated in this thesis. In Chapter 1, stochastic mechanics and diffusion theory are reviewed, using the Guerra-Morato variational principle to establish the connection with the Schroedinger equation. Chapter II settles the first of the questions raised above. Using PDE methods, the diffusions of stochastic mechanics are constructed. The result is sufficiently general to be of independent mathematical interest. In Chapter III, potential scattering in stochastic mechanics is treated and direct probabilistic methods of studying quantum scattering problems are discussed. The results provide a solid YES in answer to the second question raised above

Mandela School of Medicine, University of KwaZulu‑Natal, 2Faculty of Health Sciences, Durban University of Technology, 3School of Health Sciences, University of KwaZulu‑Natal, Durban, South Africa Introduction: Following policy implementations to redress previous racial and gender discrepancies, this study explored how gender impacted on the clinical experiences of final-year medical students during their undergraduate training. It also gathered their perceptions and expectations for the future.Methods: This cross-sectional, mixed-method study used a purposive sampling method to collect data from the participants (n=94. Each respondent was interviewed by two members of the research team. The quantitative data were entered into Excel and analyzed descriptively. The qualitative data were transcribed and thematically analyzed.Results: The majority of the respondents still perceived clinical practice as male dominated. All respondents agreed that females faced more obstacles in clinical practice than males. This included resistance from some patients, poor mentoring in some disciplines, and less support from hostile nurses. They feared for their personal safety and experienced gender-based stereotyping regarding their competency. Males thought that feminization of the profession may limit their residency choices, and they reported obstacles when conducting intimate examinations and consultations on female patients. Both males and females expressed desire for more normalized work hours to maintain personal relationships.Conclusion: Social redress policies have done much to increase equal access for females to medical schools. Cultural values and attitudes from mentors, peers, and patients still impact on the quality of their clinical experiences and therefore also their decisions regarding future clinical practice. More mentoring and education may help

2011-07-01

The aim of this study was to estimate the incidence of acute malnutrition and to identify predictors of case fatality among burn patients in the poorest South African province, Eastern Cape. This longitudinal follow-up study was conducted among consecutive burn patients admitted to Nelson Mandela Academic Hospital, Mthatha, South Africa, between 2006 and 2008. Patients were monitored and treated daily from admission to discharge. Outcomes were acute protein malnutrition and mortality. Patients' demography, total body surface area (TBSA) of the burn, cause of the burn, weight, height, location of the burn, hemoglobin, serum albumin, wound infection, and antibiotics after culture and sensitivity results were the potential predictors of in-hospital mortality. A Cox's proportional hazards model for the time to death was then used to identify independent predictors of mortality after adjusting for confounding factors. Kaplan-Meier survival curves were generated for each arm of exposure status. In all, 67 patients (35 males, 59 children) were studied. The mean (range) age was 8±12 years (1 month to 59 years). The cumulative incidence of acute malnutrition was 62.0% (n=42): 46.3% (n=31) at admission and 15.7% (n=11) after 7 days of hospitalization. Incidence of mortality was 16.4% (n=11 with in-hospital acute malnutrition). The only significant and independent predictors of mortality were total body surface area (TBSA) burn>40% [hazard ratio (HR) 10.5, 95% confidence interval (CI) 1.7-63; P<0.01] and affected anterior trunk (HR 4.4, 95% CI 1.3-14.7; P=0.018). Urgent prevention strategies of burns and evidence-based practice with early nutritional supplementation are needed to reduce high rates of malnutrition and mortality.

Nelson], particularly the berries, known also as seaberries, or Siberian pineapples, are characterized by a unique composition of bioactive compounds: phenolic compounds, vitamins (especially vitamin C, unsaturated fatty acids, and phytosterols such as beta-sitosterol. These berries, together with the juices, jams, and oils made from them, have a range of beneficial antioxidant, anti-inflammatory, and anticancer effects. This short review discusses whether sea buckthorn may represent a “golden mean” for the treatment of cancers: It has anti-proliferation properties and can induce apoptosis and stimulate the immune system, and sea buckthorn oil counteracts many side effects of chemotherapy by restoring kidney and liver function, increasing appetite, and keeping patients in general good health. Although the anticancer activity of sea buckthorn has been confirmed by many in vitro and animal in vivo studies, the treatment and prophylactic doses for humans are unknown. Therefore, greater attention should be paid to the development of well-controlled and high-quality clinical experiments in this area.

Let $H_{P,\\sigma}$ be the single-electron fiber Hamiltonians of the massless Nelson model at total momentum $P$ and infrared cut-off $\\sigma>0$. We establish detailed regularity properties of the corresponding $n$-particle ground state wave functions $f^n_{P,\\sigma}$ as functions of $P$ and $\\sigma$. In particular, we show that \\[ |\\partial_{P^j}f^{n}_{P,\\sigma}(k_1,\\ldots, k_n)|, \\ \\ |\\partial_{P^j} \\partial_{P^{j'}} f^{n}_{P,\\sigma}(k_1,\\ldots, k_n)| \\leq \\frac{1}{\\sqrt{n!}} \\frac{(c\\lambda_0)^n}{\\sigma^{\\delta_{\\lambda_0}}} \\prod_{i=1}^n\\frac{ \\chi_{[\\sigma,\\kappa)}(k_i)}{|k_i|^{3/2}}, \\] where $c$ is a numerical constant, $\\lambda_0\\mapsto \\delta_{\\lambda_0}$ is a positive function of the maximal admissible coupling constant which satisfies $\\lim_{\\lambda_0\\to 0}\\delta_{\\lambda_0}=0$ and $\\chi_{[\\sigma,\\kappa)}$ is the (approximate) characteristic function of the energy region between the infrared cut-off $\\sigma$ and the ultraviolet cut-off $\\kappa$. While the analysis of the first derivative is relatively straightforward, the second derivative requires a new strategy. By solving a non-commutative recurrence relation we derive a novel formula for $f^n_{P,\\sigma}$ with improved infrared properties. In this representation $\\partial_{P^{j'}}\\partial_{P^{j}}f^n_{P,\\sigma}$ is amenable to sharp estimates obtained by iterative analytic perturbation theory in part II of this series of papers. The bounds stated above are instrumental for scattering theory of two electrons in the Nelson model, as explained in part I of this series.

Full Text Available The aim of this study was to investigate organisational commitment in an organisation that had recently experienced organisational restructuring (a merger. The psychological contract that exists between employees and organisations is brittle due to many organisational changes that stem from organisational restructuring.  When psychological contracts are breached, employees may experience reduced commitment to the organisation.  The target population for this study consisted of all employees working at three recently-merged higher education institutions in the Nelson Mandela Metropolis (n=100 and a self-administered questionnaire was distributed amongst staff.  The results indicated that an increase in the number of positive human resource management (HRM practices reported by respondents correlated with a decrease in violation and breach of the psychological contract, despite organisational restructuring.  It was further revealed that effective management of the psychological contract is crucial during organisational restructuring, in order to maintain the commitment and loyalty of employees.

Despite affecting men, women, and children for millennia, tuberculosis (TB) is the most neglected disease. In contrast, the global response to HIV has reached a defining moment. By uniting efforts, promptly integrating major scientific findings for both treatment and prevention, and scaling up services, the once inconceivable end to the HIV epidemic may no longer be an illusion. "The world has made defeating AIDS a top priority. This is a blessing. But TB remains ignored" - Nelson Mandela. While there is no doubt that revolutionary diagnostics and new and repurposed drugs have provided some hope in the fight against TB, it is evident that scientific advances on their own are inadequate to achieve the World Health Organization's ambitious goal to end TB by 2035. In this article, the consequences of a myopic and conventional biomedical approach to TB, which has ultimately permeated to the level of individual patient care, are highlighted.

The Arapahoe snowfly, Arsapnia arapahoe (Nelson & Kondratieff, 1988) (Plecoptera: Capniidae) is a candidate species warranted for listing under the Endangered Species Act. Prior to this study, A. arapahoe was known from only two tributaries of the Cache la Poudre River in Larimer County, Colorado: Young Gulch and Elkhorn Creek. The objectives of this study were to determine the distribution of this endemic stonefly, and to identify sympatric species as possible surrogate indicators of its occurrence. Eighty-four streams were sampled within the expected geographical range and emergence time-period from 2013 to 2017. Adults of A. arapahoe were discovered in 19 first-, second-, and fourth-order streams beyond the original type localities tributary to the Cache la Poudre River. The new and recently recorded localities were discovered in the Big Thompson River, St. Vrain River, Boulder Creek, and Upper South Platte River Watersheds. Two species, A. decepta (Banks, 1897) and Capnia gracilaria Claassen, 1924, always co-occurred with A. arapahoe, suggesting this species pair may serve as a surrogate indicator of suitable stream habitat for A. arapahoe. Suggestions for future investigation into the distribution, life-history, and habitat of A. arapahoe are presented to aid the conservation of this rare and endemic Colorado stonefly.

Prevention of new HIV infections is a critical imperative for South Africa; the prevention of mother-to-child transmission (PMTCT) is one of the most efficacious HIV prevention interventions. Assessment of a PMTCT programme to determine missed opportunities. The Kouga local service area (LSA), bordering Nelson Mandela Bay Municipality (Port Elizabeth) in the Eastern Cape. An assessment was conducted in 2007 before implementing technical support for strengthening the PMTCT programme, including: interviews with 20 PMTCT managers, 4 maternity staff and 27 other health workers on service provision, management, infrastructure, human resources and the health information system; 296 antenatal clinic users on their service perceptions; 70 HIV-positive women on HIV knowledge, infant feeding, coping, support and service perceptions; 8 representatives from community organisations and 101 traditional health practitioners (THPs). Observations were conducted during site visits to health facilities, and the District Health Information System (DHIS) data were reviewed. Staff had high levels of awareness of HIV policies and most had received some relevant training. Nevirapine uptake varied by clinic, with an average of 56%. There were many missed opportunities for PMTCT, with 67% of pregnant women tested for HIV and only 43% of antenatal care attendees tested during a previous pregnancy. Only 6% of HIV-positive women reported support group participation. Reducing missed opportunities for PMTCT requires strengthening of the formal health sector, intersectoral liaison, and greater community support. Priority areas that require strengthening in the formal health sector include HIV counselling and testing; family planning and nutrition counselling; infant follow-up; human resources; and monitoring and evaluation.

There is limited literature on hypernatreamia in the setting of hyperglycaemic crisis. This is despite the fact that the presence of hypernatreamia may impact on the classification of hyperglycaemic crisis and its management particularly with regards to the nature of fluid therapy. We determined the prevalence of hypernatreamia and its associated factors at presentation for hyperglycaemic crisis. This was a retrospective review of data for hyperglycaemic crisis admissions in Nelson Mandela Academic Hospital, Mthatha, South Africa. The prevalence of hypernatreamia (uncorrected Serum Sodium at presentation >145 mmol/L) was determined. Hyperosmolality was defined by calculated effective osmolality >320 mosmols/Kg. Multivariate logistic regression was undertaken using variables that were statistically significant in univariate analysis to ascertain those that were independently associated (Odds Ratio (OR) with 95% Confidence Interval (CI)) with hypernatreamia. The prevalence of hypernatreamia in our admissions for hyperglycaemic crisis was 11.7% (n = 32/273 including 171 females and 102 males). All admissions with hypernatreamia met the criteria for hyperosmolality. Age ≥ 60 years (OR = 3.9 95% CI 1.3-12.3; P = 0.018), Altered level of consciousness (OR = 8.8 95% CI 2.3-32.8; P < 0.001) and a new diagnosis of diabetes (OR = 3.7 95%CI 1.2-11.5; P = 0.025) were independently associated with hypernatreamia. The prevalence rate of hypernatreamia in hyperglycaemic admissions was high with all hypernatreamic admissions meeting the criteria for hyperosmolality. Advanced age, altered conscious level and a new diagnosis of diabetes were independently associated with hypernatreamia.

Radiocarbon dates from the holocene levels at Nelson Bay Cave, and an interim report on their associations

Various changes in the cultural material derived from the later Holocene levels of Nelson Bay Cave can be pinpointed in temporal context by means of a large series of radiocarbon dates, such as Carbon 13 and Carbon 14 covering the past 6 000 years. As excavations and analysis of the recovered materials proceeded, radiocarbon dates were sought in order to provide a chronological frame work for what are taken to be significant features in the history of the site, and these are discussed in the article. Several pottery and assumed sheep remains were recorded. Six human burials were also recovered and this helps with the characterization of Holocene burial practices

Late Otiran sedimentation and glacial chronology in the Warwick valley, southeast Nelson

International Nuclear Information System (INIS)

Mabin, M.C.G.

1983-01-01

Approximately 14 m of sediment are exposed in a road cutting beneath a landslide deposit in the Warwick valley, southeast Nelson, New Zealand. Three radiocarbon dates and 5 pollen spectra were obtained from organic horizons in these sediments. The dates indicate that lacustrine sedimentation predominated from before 17 500 until 14 450 years ago. This was interrupted by a brief period of gravel aggradation between 17 500 and 16 650 years ago, which is attributed to a glacial advance. Vegetation at the site was consistently dominated by Cyperaceae, with some Gramineae, suggesting a bleak, treeless landscape. Correlation of this information with other radiocarbon dated sites indicates the need for some revision of the chronology of the late Otira Glaciation. A late phase of the Kumara 2 2 advance occurred between 17 000 and 16 000 years ago, and the Kumara 3 1 advance did not occur until after about 15 000 years ago. The end of the Otira Glaciation probably occurred between 13 000 and 12 500 years ago. (auth)

Ulrich, Rolf; Miller, Jeff

2015-12-01

Simonsohn, Nelson, and Simmons (2014) have suggested a novel test to detect p-hacking in research, that is, when researchers report excessive rates of "significant effects" that are truly false positives. Although this test is very useful for identifying true effects in some cases, it fails to identify false positives in several situations when researchers conduct multiple statistical tests (e.g., reporting the most significant result). In these cases, p-curves are right-skewed, thereby mimicking the existence of real effects even if no effect is actually present. (c) 2015 APA, all rights reserved).

In recent years a series of trials has sought to define the optimal protocol for everolimus-based immunosuppression in heart transplantation, with the goal of minimizing exposure to calcineurin inhibitors (CNIs) and harnessing the non-immunosuppressive benefits of everolimus. Randomized studies have demonstrated that immunosuppressive potency can be maintained in heart transplant patients receiving everolimus despite marked CNI reduction, although very early CNI withdrawal may be inadvisable. A potential renal advantage has been shown for everolimus, but the optimal time for conversion and the adequate reduction in CNI exposure remain to be defined. Other reasons for use of everolimus include a substantial reduction in the risk of cytomegalovirus infection, and evidence for inhibition of cardiac allograft vasculopathy, a major cause of graft loss. The ongoing MANDELA study is a 12-month multicenter, randomized, open-label, parallel-group study in which efficacy, renal function and safety are compared in approximately 200 heart transplant patients. Patients receive CNI therapy, steroids and everolimus or mycophenolic acid during months 3 to 6 post-transplant, and are then randomized at month 6 post-transplant (i) to convert to CNI-free immunosuppression with everolimus and mycophenolic acid or (ii) to continue reduced-exposure CNI, with concomitant everolimus. Patients are then followed to month 18 post-transplant The rationale and expectations for the trial and its methodology are described herein. Copyright © 2015 Elsevier Inc. All rights reserved.

To describe the frequencies, presenting characteristics (demographic, clinical and biochemical) and outcomes (duration of admission and mortality rates) for various types of hyperglycaemic crisis. Retrospective review of medical records of patients with hyperglycaemic crisis admitted to Nelson Mandela Academic Hospital, Mthatha, E Cape, from 1 January 2008 to 31 December 2009. Outcome measures were duration of admission and mortality. Data were available for 269 admissions (response rate 81.0%), 169 females and 100 males. Admissions for hyperglycaemia (HG, N=119), and non-hyperosmolar diabetic ketoacidosis (NHDKA, N=97) were more frequent than those for hyperosmolar hyperglycaemic state (HHS, N=29) and hyperosmolar diabetic ketoacidosis (HDKA, N=24). Duration of admission was similar in all groups. Mortality was high in all groups, but was higher in patients with HDKA (37.5%, risk ratio (RR) 3.88, 95% confidence interval (CI) 1.41 - 10.67, p=0.009), HHS (31.0%, RR 2.91, 95% CI 1.09 - 7.75, p=0.033) and HG (19.5%, RR 1.56, 95% CI 0.75 - 3.21, p=0.236) than in those with NHDKA (13.4%). HDKA (62.5%) was associated with new-onset diabetes more often than NHDKA (27.8%), HHS (44.8%) or HG (17.6%) (p<0.0001). An altered level of consciousness was more frequent in HDKA than NHDKA admissions (RR 5.71, 95% CI 1.90 - 17.17, p=0.002). Duration of hospital stay was similar across groups. Mortality rates were high in all groups. New-onset diabetes, altered level of consciousness and mortality were more characteristically associated with HDKA than any of the other types of hyperglycaemic crisis. Optimal glycaemic control in known diabetic patients will reduce rates of hyperglycaemic crisis admissions.

Full Text Available In 1990, Bruns and Merchant (1990 surveyed earnings-management practices and asked the readership of the Harvard Business Review to rate the acceptability of those practices. Prior to the Bruns and Merchant (1990 study, the morality of short-term earnings-management was of little concern to researchers and accounting practitioners. However, in the light of increased financial frauds and failures, new and increased emphasis has been placed on the importance of the concepts of earnings quality and earnings-management practices. Despite increased research focusing on business ethics since 1990, there is little evidence that the profession is educating accountants about earnings-management practices. This study compares the results of studies on earnings-management practices. Students and business managers were surveyed at the Nelson Mandela Metropolitan University (NMMU and these results were compared to studies prior to the Sarbanes-Oxley Act 2002 in the USA. The aim of the study is to determine if there have been changes in attitudes towards earnings-management practices since the acceptance of the Sarbanes-Oxley Act.

An Education Strategy to Respond to Medicine Inequality in Africa.

People living in Africa face a heavy and wide-ranging burden of disease that takes an incalculable toll on social and economic development as well as shortening life expectancy (life expectancy in Tanzania is about 60 vs. about 80 in the United States and Europe. Further, the pharmaceutical market in developing countries is immature and may not support quality medicines. In many cases, a tender system is used, and medicines are bought by the government at the lowest price. In addition to access to medicines, a number of pharmaceutical sciences problems are apparent. The availability of infrastructure and especially standard instruments such as HPLC and X-ray diffraction is minimal. Additionally, there is an important need to increase access to advanced education for men and women in Africa, especially access to state-of-the-art scientific education. Utilizing the mandate of Nelson Mandela, Purdue's conceptual approach has been to utilize education to combat these problems. Copyright © 2017 American Pharmacists Association®.

2013-01-01

Incomplete patient medical history compromises the quality of care provided to a patient while well-kept, adequate patient medical records are central to the provision of good quality of care. According to research, patients have the right to contribute to decision-making affecting their health. Hence, the researchers investigated their views regarding a paper-based system and an electronic medical record (EMR). An explorative approach was used in conducting a survey within selected general practices in the Nelson Mandela Metropole. The majority of participants thought that the use of a paper-based system had no negative impact on their health. Participants expressed concerns relating to the confidentiality of their medical records with both storage mediums. The majority of participants indicated they prefer their GP to computerise their consultation details. The main objective of the research on which this poster is based was to investigate the storage medium of preference for patients and the reasons for their preference. Overall, 48% of the 85 participants selected EMRs as their preferred storage medium and the reasons for their preference were also uncovered.

The importance of executive leadership in creating a post-merged organisational culture conducive to effective performance management

Gary W. Paul

2013-01-01

Research purpose: To develop a theoretical model from the insights gleaned from the literature study, interviews with senior human resource (HR practitioners at participating institutions and the empirical study. Based on the empirical findings, this model was refined and resulted in the eight-step integrated post-merged organisational culture creation model. Motivation for the study: The negligible attention given to the design of mechanisms supportive of post-merged organisational culture creation emphasised the need for this study. The high percentage of merger failures attributable to ineffective post-merged organisational culture integration further contributed. Research design, approach and method: A quantitative study was conducted at three merged South African higher education institutions, namely Nelson Mandela Metropolitan University, Cape Peninsula University of Technology and Durban University of Technology. Respondents occupied the following functional categories: executive management, senior and line management, HR practitioners and non-HR or non-management. Main findings: Respondents perceived the role of executive management to be the most important step of the theoretical model which formed the basis for the empirical survey questionnaire. This step, which obtained the highest summated mean score in all three institutions and across all functional categories, was depicted as Step 5 of the model. Practical/managerial implications: The refined eight-step integrated post-merged organisational culture creation model will significantly enhance the creation of a post-merged organisational culture conducive to effective performance management. Contribution/value-add: This study addressed the void regarding a model to guide the creation of a post-merged organisational culture conducive to effective performance management in higher education institutions as well as merged corporate organisations.

A key aspect of the success of a PBL curriculum is the effective implementation of its small group tutorials. Diversity among students participating in tutorials may affect the effectiveness of the tutorials and may require different implementation strategies. To determine how students from diverse backgrounds perceive the effectiveness of the processes and content of the PBL tutorials. This study also aims to explore the relationship between students' perceptions of their PBL tutorials and their gender, age, language, prior educational training, and secondary schooling. Data were survey results from 244 first-year student-respondents at the Nelson Mandela School of Medicine at the University of KwaZulu-Natal in South Africa. Exploratory factor analysis was conducted to verify scale constructs in the questionnaire. Relationships between independent and dependent variables were investigated in an analysis of variance. The average scores for the items measured varied between 3.3 and 3.8 (scale value 1 indicated negative regard and 5 indicated positive regard). Among process measures, approximately two-thirds of students felt that learning in a group was neither frustrating nor stressful and that they enjoyed learning how to work with students from different social and cultural backgrounds. Among content measures, 80% of the students felt that they learned to work successfully with students from different social and cultural groups and 77% felt that they benefited from the input of other group members. Mean ratings on these measures did not vary with students' gender, age, first language, prior educational training, and the types of schools they had previously attended. Medical students of the University of KwaZulu-Natal, regardless of their backgrounds, generally have positive perceptions of small group learning. These findings support previous studies in highlighting the role that small group tutorials can play in overcoming cultural barriers and promoting unity and

The aim of the study was to understand how lottery incentives influenced the HIV counselling and testing (HCT) behaviour and behaviour intention of shop-floor workers who participated in a workplace HCT campaign initiative in two companies in the Nelson Mandela Bay municipality, South Africa. A post-test only quasi-experimental approach was used. The data were first collected, using a self-administered cross-sectional survey instrument, among the control group (n = 88) followed by the experimental group (n = 110) after the advent of HIV testing and lotteries was announced. HIV testing behaviour data were collected on the days of the HIV testing events. The theory of planned behaviour (TPB) was used as guiding theory. Principal component analysis (PCA), t- and chi-square tests, and logistic regression were conducted to analyse the data. A significant increase in the mean scores of the experimental as compared to the control condition for the subjective norm's construct (t = -3.55, p < 0.001) and HIV testing behaviour intention (χ 2 = 12.35, p < 0.001) was measured following the announcement of lottery incentives. The constructs of TPB explained 40% of the variance in HCT behaviour intention (R 2 = 0.40). The strongest predictor of behaviour intention was the subjective norm (B = 0.435 and p < 0.001), followed by the attitudinal component (B = 0.323 and p = 0.040). The announcement of lotteries made shop-floor workers develop a stronger intention to participate in workplace HIV testing through anticipation of stronger social support and encouragement. It was not possible to link behaviour intention to behaviour due to missing data. The findings point to the importance of providing workers with an opportunity to openly discuss HIV testing thus allowing mitigation of HIV stigma and discrimination and permitting HIV testing to become socially sanctioned and seen as part of a collective effort.

Full Text Available Orientation: Focus was placed on the important role of executive management in creating a post-merged organisational culture conducive to effective performance management.Research purpose: To develop a theoretical model from the insights gleaned from the literature study, interviews with senior human resource (HR practitioners at participating institutions and the empirical study. Based on the empirical findings, this model was refined and resulted in the eight-step integrated post-merged organisational culture creation model.Motivation for the study: The negligible attention given to the design of mechanisms supportive of post-merged organisational culture creation emphasised the need for this study. The high percentage of merger failures attributable to ineffective post-merged organisational culture integration further contributed.Research design, approach and method: A quantitative study was conducted at three merged South African higher education institutions, namely Nelson Mandela Metropolitan University, Cape Peninsula University of Technology and Durban University of Technology. Respondents occupied the following functional categories: executive management, senior and line management, HR practitioners and non-HR or non-management.Main findings: Respondents perceived the role of executive management to be the most important step of the theoretical model which formed the basis for the empirical survey questionnaire. This step, which obtained the highest summated mean score in all three institutions and across all functional categories, was depicted as Step 5 of the model.Practical/managerial implications: The refined eight-step integrated post-merged organisational culture creation model will significantly enhance the creation of a post-merged organisational culture conducive to effective performance management.Contribution/value-add: This study addressed the void regarding a model to guide the creation of a post-merged organisational

The HIV/AIDS pandemic: new ways of preventing infection in men.

Short, R V

2004-01-01

Nelson Mandela has recently said that HIV/AIDS is the greatest health crisis in human history. At the end of 2001, UNAIDS estimated that there were 40 million people living with the infection, with 5 million new cases, and 3 million deaths per year. About half the infected individuals are men, and heterosexual intercourse is the commonest route of infection. Although condoms remain the first line of defence, they are unpopular in parts of Africa, where the pandemic is worst, so an alternative is needed. Post-coital penile hygiene has received little attention. Wiping the glans penis and inner foreskin immediately after intercourse with an acidic solution like lemon or lime juice, or even vinegar, should immediately kill the virus and might prevent infection; clinical trials are urgently needed. Several studies in Africa and India have now conclusively demonstrated a 2-7-fold protective effect of male circumcision against HIV infection. Circumcision removes the inner foreskin and the frenulum, which are the prime sites of HIV entry into the penis. Since male circumcision also protects men from human papilloma virus infection, and their wives from cervical carcinoma, the procedure should be encouraged in developed and developing countries.

Full Text Available Los métodos de evaluación de la uniformidad de riego estiman las condiciones hidráulicas de funcionamiento del sistema de riego y su influencia en la aplicación de láminas de agua, con base en las necesidades hídricas de un cultivo. El modelo de evaluación utilizado en la presente investigación fue el polinomial. El ensayo evaluó el funcionamiento del sistema de riego con 4 presiones de operación distintas, medidas a la salida de la válvula del módulo de riego, y por cada presión de operación se tomaron 16 datos de caudales, en 5 módulos de riego instalado con el aspersor autocompensado Nelson R10. Como resultado se obtuvo el coeficiente de uniformidad, el coeficiente de distribución, el área adecuadamente irrigada y el factor de adecuación del riego. Uno de los principales resultados fue la no existencia de diferencia significativa entre las presiones mientras esta se mantengan en el rango de autocompensación; por otro lado, en el coeficiente de distribución sí existen diferencias significativas entre los tratamientos, a pesar de que todos dan valores mayores al 90%, en contraste con los porcentajes del área relativa adecuadamente regada, que no superan el 50% en ninguno de los tratamientos. Con lo anterior se pudo validar y verificar que el aspersor Nelson R10 autocompensado, una vez instalado en campo, cumple con las características técnicas de operación expuestas en el catálogo del fabricante, sin embargo, sí se debe manejar y controlar la lámina de riego aplicada.

Tradição, tragicidade e crítica social em Dorotéia, a “farsa irresponsável” de Nelson Rodrigues

Full Text Available http://dx.doi.org/10.5007/2176-8552.2013n16p163 A verossimilhança sempre foi amplamente explorada pela imaginação artística. Poetas trágicos e cômicos tramaram situações as mais criativas, buscando mover o público ao riso ou às lágrimas. Tradicionalmente, entretanto, recaem limites sobre as representações dramáticas, a depender dos efeitos que os autores pretendem provocar. Assim, ainda que eventos impossíveis tenham participado da tragédia desde suas origens, e ainda que o humor tenha sido ocasionalmente acolhido nas tramas, o tratamento sério da ação sempre foi exigência da forma, de maneira a que o trágico não se fizesse cômico. Com o passar dos séculos, dramaturgos desafiariam as definições de tragédia e comédia, preparando as bases para o drama social. A dramatização de conflitos da vida burguesa rapidamente absorveria um amplo espectro de tons emocionais, abolindo convenções antigas em favor de um gênero que se quer lócus privilegiado de crítica social. O trágico poderia agora ser dramatizado sob perspectivas as mais diversas, inclusive farsescas. Este ensaio examina a tragicidade na peça Dorotéia, de Nelson Rodrigues, focalizando as relações da obra com a tradição e considerando, através do conceito de “dispositivo” formulado por Agamben, estratégias utilizadas pelo dramaturgo para produzir uma crítica sarcástica a valores e instituições sociais.

ORATIO: ADDRESS TO COMMEMORATE THE 2013 MARTIN LUTHER KING DAY AT THE LAW FACULTY, UNIVERSITY OF MICHIGAN

2013-08-01

Full Text Available The paper commences by considering the similarity between Dr King, MK Gandhi and Nelson Mandela and argues that they are high mimetic figures who inspire us to be better. Their legacy and memory operate as a yardstick by which we can evaluate the conduct of those exercising public and private power over us. Each remains dominant in his respective society decades after passing on or leaving public life, and the paper suggests that very little societal value is had by deconstructing their lives and judging facets of their lives through the prism of latter day morality. We gain more by leaving their high mimetic status undisturbed. There is a clear link between their various struggles with King being heavily influenced by the writings and thinking of Gandhi, who commenced his career as a liberation activist in South Africa. King was instrumental in commencing the discourse on economic sanctions to force the Apartheid government to change and the Indian government had a long and committed relationship with the ANC. The second half of the paper turns to an analysis of how Dr King's legacy impacted directly and indirectly on developments in South Africa. One of the key objectives of the Civil Rights movement in the USA was to attain substantive equality and to improve the quality of life of all. The paper then turns to assessing the extent to which democratic South Africa has achieved these objectives and concludes that the picture is mixed. Important pioneering changes such as enabling gays and lesbians to marry have taught important lessons about taking rights seriously. However, despite important advancements, neither poverty nor inequality has been appreciably reduced. One of the major failures has been the inability to provide appropriate, effective and relevant education to African children in public schools. Effectively educating previously disadvantaged persons represents one of the few means at our disposal of reducing inequality and breaking

Full Text Available The Eastern Cape redfin, Pseudobarbus afer, has long been considered to be a single widespread and variable species occurring in multiple isolated river systems in the Cape Fold Ecoregion (CFE at the southern tip of Africa. Mitochondrial cytochrome b and control region sequence data of individuals from populations currently assigned to P. afer across the species’ distribution range revealed existence of four deeply divergent taxonomic units: (i the Mandela lineage confined to the Sundays, Swartkops and Baakens river systems, (ii the Krom lineage endemic to the Krom River system, (iii the St Francis lineage occurring in the Gamtoos and adjacent river systems, and (iv the Forest lineage occurring in several coastal river systems from the Tsitsikamma to the Klein Brak River system. The Forest lineage is closely related to P. phlegethon from the Olifants River system on the west coast of South Africa, suggesting that it does not belong to P. afer s.l. Herein we focus on the three lineages within the P. afer s.l. complex and provide new diagnosis for P. afer s.s (Mandela lineage, revalidate P. senticeps (Krom lineage as a distinct species, and describe a new species P. swartzi (St Francis lineage. The three species exhibit subtle differences, which explains why they were previously considered to represent a single variable and widespread species. Pseudobarbus senticeps differs from both P. afer and P. swartzi by having fewer (i.e. larger scales (25–33, mode 29 lateral line scale series; 10–12, mode 11 circumpeduncular scales and presence of a lateral stripe which terminates in a conspicuous triangular blotch at the base of the caudal fin. Long barbels which reach or surpass the vertical through the posterior edge of the eye further separate P. senticeps from P. afer s.s. which possesses simple short barbels which do not reach the vertical through the posterior margin of the eye. Pseudobarbus afer s.s differs from P. swartzi sp. n. by possession

The complete mitochondrial genome of the gall-forming fly, Fergusonina taylori Nelson and Yeates (Diptera: Fergusoninidae).

2011-10-01

The monogeneric family Fergusoninidae consists of gall-forming flies that, together with Fergusobia (Tylenchida: Neotylenchidae) nematodes, form the only known mutualistic association between insects and nematodes. In this study, the entire 16,000 bp mitochondrial genome of Fergusonina taylori Nelson and Yeates was sequenced. The circular genome contains one encoding region including 27 genes and one non-coding A+T-rich region. The arrangement of the protein-coding, ribosomal RNA (rRNA) and transfer RNA (tRNA) genes was the same as that found in the ancestral insect. Nucleotide composition is highly A+T biased. All of the protein initiation codons are ATN, except for nad1 which begins with TTT. All 22 tRNA anticodons of F. taylori match those observed in Drosophila yakuba, and all form the typical cloverleaf structure except for tRNA-Ser((AGN)) which lacks a dihydrouridine (DHU) arm. Secondary structural features of the rRNA genes of Fergusonina are similar to those proposed for other insects, with minor modifications. The mitochondrial genome of Fergusonina presented here may prove valuable for resolving the sister group to the Fergusoninidae, and expands the available mtDNA data sources for acalyptrates overall.

A search has been carried out for a long-lived particle having an interaction length lambdasub(m) = 300 to 2,000 cm -2 in air. Such a particle, called the mandela, has been proposed by the Leeds group to explain an anomalous energy spectrum of particles observed near sea level with a shallow spectrometer. Data taken at mountain altitude with a deep spectrometer has been examined for compatibility with the existence of the mandela. Although the data tend to favor the mandela hypothesis the results are not conclusive and appear to be explainable by conventional means. (orig.) [de

Full Text Available This article discusses the production of a genealogical text in Chronicles (1 Chron. 2:3-4:23 which probably served as a key to membership within a collective community in the province of Yehud in the Persian period of the Second Temple era. The article starts with a discussion of how genealogies work in Southern Africa: firstly, within a particular church community ravished by racial tensions, secondly, within the African community during Nelson Mandela's presidential inauguration and thirdly, albeit briefly, within the context of Swazi praise songs, where the ideological role of genealogies serves to bolster traditional values. Because it is accepted that in ancient societies writing directly relates to power in ancient societies, the problem of elite groups in society is discussed before the text of 1 Chronicles 2:3-4:23 is analysed. The latter text is discussed with relation to Joel Weinberg's thesis of the bêt ’abót, the strange women in Ezra and Nehemia, and the influence of the Persian administration on the inhabitants of the Ancient Near East. Finally, the elite community is seen as a group of loyal Persian administrators, despite the fact that they were (the children of exiles.

Motivation to Reduce Risk Behaviors While in Prison: Qualitative Analysis of Interviews with Current and Formerly Incarcerated Women.

Abad, Neetu; Carry, Monique; Herbst, Jeffrey H; Fogel, Catherine I

2013-10-01

Prison is an environment in which programs can be implemented to change harmful behaviors among high-risk populations. Incarcerated women experience high rates of HIV and other sexually transmitted diseases (STDs), yet little research has examined women's motivation to reduce risky behaviors during incarceration. In-depth individual interviews were conducted with former and current women prisoners in two North Carolina correctional facilities and analyzed to identify barriers and facilitators of behavior change while in prison. Analyses revealed key motivators of behavior change: Viewing prison as a place to recover from past trauma, removing oneself from negative social networks, gaining access to needed mental and physical health services, and engaging in self-care and self-reflection. Barriers to behavior change include fear of recidivism, stigma of being in prison, and return to undesirable social networks post-release. Moreover, women noted that the provision of mental health services, educational enhancement and housing assistance could help them reduce engagement in high-risk behaviors after their incarceration. These findings can be incorporated into HIV/STD risk reduction interventions to facilitate positive behavior change among incarcerated women prisoners. Prison itself is a tremendous education in the need for patience and perseverance. It is above all a test of one's commitment.-Nelson Mandela, 1995.

Full Text Available Generation Z was the foremost generation to have prevalent access to the Internet from an early age. Technology has strongly influenced this generation in terms of communication, education and consequently their academic information behaviour. With the next generation of scholars already being trained, in a decade, most of the researchers will be mainly digital natives. This study sought to establish the library information resources use pattern in relation to users’ preferred information media in order to render better academic information services to library users. A total of 390 respondents were surveyed at the Nelson Mandela University and the University of Fort Hare using quantitative and qualitative methods. Most of the respondents, 82.3%, were aged between 18 and 23 years; while the average library use time was two hours daily. The most utilised library resource is the Wi-Fi with e-books and e-journals found to be lowly utilised. Records from the E-librarians revealed that undergraduate students account for no more than 6% of total users of electronic databases with 62.3% of the respondents preferring print information resources. Better understanding of library users’ demographics and information media preference is essential in proving the right kind of information services to Generation Z library users.

A cinema of presence and proximity: Gunvor Nelson's collage films and the aesthetics of the signaletic material before the electronic signal

Directory of Open Access Journals (Sweden)

John Sundholm

2012-06-01

Full Text Available This essay argues for the importance of an intersubjective and impure film theory in which the signal and the signaletic is considered as figures for approaching film. This in order to make the argument that the signaletic mode indeed enables a novel perspective on moving image history. The aesthetics of the signaletic has thus a history preceding that of electronic media, in particular when it comes to animation and experimental film. When constructing such an archaeology, however, dichotomies into sign and signal should be avoided; otherwise, the complexity of many of the films is reduced. In order to illuminate the latter point, four films by Gunvor Nelson is analyzed (both analog and digital, showing not only how both sign and signal interact but also how the aesthetics of the signal and the signaletic material is not dependant on the electronic as such.

Location decision strategies for improving SMME business performance

Shereen Barnard

2011-12-01

Full Text Available Purpose: The primary objective of this study is to investigate the macro-environmental factors that may influence location decisions and how these choices may affect the business performance of SMMEs. Problem investigated: SMMEs in South Africa play an increasingly important role in stimulating economic activity, growth and employment creation. However, many SMMEs cease to exist within the first five years of operation due to various challenges faced by SMMEs on a daily basis. Many SMMEs owners disregard the importance of location, yet the geographical location can negatively influence the survival of the business. Several factors influence the choice of the location, which will ultimately have either a positive or negative effect on business performance. Methodology: A positivistic research methodology was adopted for this study. Seven hypotheses were constructed to achieve the primary objective of this study. The population for this study consisted of SMMEs in the Nelson Mandela Metropole from which a convenience sample of 175 SMMEs was selected. The measuring instrument, a self-developed questionnaire, consisted of three sections. The data collected included the demographical data of the respondents and their businesses, statements on location and various factors influencing location decisions as well as measurements of business performance. Cronbach Alpha coefficients were calculated to determine the reliability of the questionnaire items.

South Africa (SA)'s Comprehensive HIV and AIDS Care, Management and Treatment (CCMT) programme has reduced new HIV infections and HIV-related deaths. In spite of progress made, 11.2% of South Africans (4.02 million) were living with HIV in 2015. The National Health Laboratory Service (NHLS) in SA performs CD4 testing in support of the CCMT programme and collates data through the NHLS Corporate Data Warehouse. The objective of this study was to assess the distribution of CD4 counts <100 cells/µL (defining severely immunosuppressed HIV-positive patients) and >500 cells/µL (as an HIV-positive 'wellness' indicator). CD4 data were extracted for the financial years 2010/11 and 2014/15, according to the district where the test was ordered, for predefined CD4 ranges. National and provincial averages of CD4 counts <100 and >500 cells/µL were calculated. Data were analysed using Stata 12 and mapping was done with ArcGIS software, reporting percentages of CD4 counts <100 and >500 cells/µL by district. The national average percentage of patients with CD4 counts <100 cells/µL showed a marked decrease (by 22%) over the 5-year study period, with a concurrent increase in CD4 counts >500 cells/µL (by 57%). District-by-district analysis showed that in 2010/11, 44/52 districts had >10% of CD4 samples with counts <100 cells/µL, decreasing to only 17/52 districts by 2014/15. Overall, districts in the Western Cape and KwaZulu-Natal had the lowest percentages of CD4 counts <100 cells/µL, as well as the highest percentages of counts >500 cells/µL. In contrast, in 2014/15, the highest percentages of CD4 counts <100 cells/µL were noted in the West Rand (Gauteng), Vhembe (Limpopo) and Nelson Mandela Bay (Eastern Cape) districts, where the lowest percentages of counts >500 cells/µL were also noted. The percentages of CD4 counts <100 cells/µL highlighted here reveal districts with positive change suggestive of programmatic improvements, and also highlight districts requiring local

Central centrifugal cicatricial alopecia (CCCA) is a form of scarring hair loss most commonly seen in middle-aged African and African American women. It is rarely reported in children. The objective of the current study was to document the presence of CCCA in children and to encourage physicians to recognize early signs of CCCA in children of affected adults. Six children presented with biopsy-proven CCCA to the Department of Dermatology at Wake Forest Baptist Health and the Nelson R. Mandela School of Medicine from 2012 to 2015. Demographic characteristics, hair styling history, and family history of CCCA were noted. Examination included complete history, skin and scalp examination, photographs of the scalp, and scalp biopsies. Patient ages ranged from 14 to 19 years (mean age at onset 14 years). Five patients reported scalp symptoms such as tender papules, pruritus, and scaling. Four patients reported appreciable hair loss on the vertex of the scalp. One patient had used chemical relaxers and hair dyes in the past. Five patients had a known family history of CCCA. Because CCCA is not typically seen or suspected in children, it is likely to be misdiagnosed or underreported. The findings in these cases add weight to the concept that genetic susceptibility rather than hair care practices may play a significant role in causing CCCA. © 2016 Wiley Periodicals, Inc.

Global Climate Model Simulated Hydrologic Droughts and Floods in the Nelson-Churchill Watershed

There is uncertainty surrounding the duration, magnitude and frequency of historical hydroclimatic extremes such as hydrologic droughts and floods prior to the observed record. In regions where paleoclimatic studies are less reliable, Global Climate Models (GCMs) can provide useful information about past hydroclimatic conditions. This study evaluates the use of Coupled Model Intercomparison Project 5 (CMIP5) GCMs to enhance the understanding of historical droughts and floods across the Canadian Prairie region in the Nelson-Churchill Watershed (NCW). The NCW is approximately 1.4 million km2 in size and drains into Hudson Bay in Northern Manitoba, Canada. One hundred years of observed hydrologic records show extended dry and wet periods in this region; however paleoclimatic studies suggest that longer, more severe droughts have occurred in the past. In Manitoba, where hydropower is the primary source of electricity, droughts are of particular interest as they are important for future resource planning. Twenty-three GCMs with daily runoff are evaluated using 16 metrics for skill in reproducing historic annual runoff patterns. A common 56-year historic period of 1950-2005 is used for this evaluation to capture wet and dry periods. GCM runoff is then routed at a grid resolution of 0.25° using the WATFLOOD hydrological model storage-routing algorithm to develop streamflow scenarios. Reservoir operation is naturalized and a consistent temperature scenario is used to determine ice-on and ice-off conditions. These streamflow simulations are compared with the historic record to remove bias using quantile mapping of empirical distribution functions. GCM runoff data from pre-industrial and future projection experiments are also bias corrected to obtain extended streamflow simulations. GCM streamflow simulations of more than 650 years include a stationary (pre-industrial) period and future periods forced by radiative forcing scenarios. Quantile mapping adjusts for magnitude

Sediment cores were sampled in the estuary of the Nelson and Churchill Rivers in western Hudson Bay, as well as in the estuary of the Moisie and Sainte-Marguerite Rivers in Gulf of St. Lawrence in order to evaluate the impact of hydroelectric dams on the sedimentary regime of these estuaries. The gravity cores at the mouth of the Nelson River recorded several cm-thick rapidly deposited layers with a reverse to normal grading sequence, indicating the occurrence of hyperpycnal flows generated by major floods during the last few centuries. These hyperpycnal flows were probably caused by ice-jam formation, which can increase both the flow and the sediment concentration following the breaching of such natural dams. Following the construction of hydroelectric dams since the 1960s, the regulation of river discharge prevented the formation of hyperpycnal flows, and hence the deposition of hyperpycnites in the upper part of the cores. In the core sampled in the estuary of the Churchill River, only one hyperpycnite was recorded. This lower frequency may be due to the enclosed estuary of the Churchill River, its weaker discharge and the more distal location of the coring site.In the Gulf of St. Lawrence, grain size measurements allowed the identification of a major flood around AD 1844±4 years in box cores from both the Sainte-Marguerite and Moisie Rivers, whereas a drastic decrease in variations in the median grain size occurred around AD ~1900 in the estuary of the Sainte-Marguerite River, highlighting the offshore impact of the SM1 dam construction in the early 1900s. Furthermore, sedimentological variations in the box cores from both estuaries have been investigated by wavelet analysis and the sharp disappearance of high frequencies around AD 1900 in the estuary of the dammed river (Sainte-Marguerite River), but not in the estuary of the natural river (Moisie River), also provides evidence of the influence of dams on the sedimentary regime of estuaries.

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

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.

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.

Variation among sub-basins of the upper Nelson River in relationships between precipitation, runoff and the Pacific Decadal Oscillation

International Nuclear Information System (INIS)

McCullough, G.

2008-01-01

In this paper, I examine relationships between precipitation and river discharge in the Nelson River watershed and several global climate indices. Inter-decadal patterns in discharge and precipitation for several sub-basins closely tracked the Pacific Decadal Oscillation (PDO) through much of the 20th century. The PDO explained 53% of the variability in precipitation and 70% in discharge for the Red River (5-y averages) from 1915-1975. However, since 1975, both precipitation and discharge have increased relative to trend of the PDO. Winnipeg River discharge likewise increased relative to the PDO, but diverged earlier, beginning in 1965. The hydrograph of the Saskatchewan River followed the PDO only until mid-century, after which discharge declined relative to the PDO. The decline of discharge in the Saskatchewan River is not matched by consistent declines in precipitation, but may be partly due to consumptive use, mainly irrigation, and losses due to evaporation from large reservoirs created in the 1960s and 1970s. However, the increases in the Red and Winnipeg River are well-explained by increased spring and summer precipitation. For instance, precipitation was 20-30% higher in the decade 1996-2005 than in the previous decade. By examining historical data, we show the runoff coefficient to increase with increasing discharge, and that the proportional increase is greater in the Red than in the Winnipeg River basin. In the Red, the moderate difference in precipitation was amplified into a doubling of annual mean discharge. Comparing the same 2 periods, a smaller 10% increase in precipitation in the Winnipeg River basin explains a 27% increase in discharge. (author)

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.

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

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.

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

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

Policy and Legal Protection for Breastfeeding and Incarcerated Women in Canada.

Science.gov (United States)

Paynter, Martha Jane

2018-05-01

Most incarcerated women in Canada are mothers. Because women are the fastest growing population in carceral facilities, protecting the rights of incarcerated women to breastfeed their children is increasingly important. There is considerable evidence that incarcerated women in Canada experience poor physical and mental health, isolation, and barriers to care. Incarcerated women and their children could benefit significantly from breastfeeding. This Insight in Policy explores policy and legal protection for breastfeeding in Canada as it relates to carceral facilities, considers key cases regarding breastfeeding rights among incarcerated women, and presents recommendations for policy development and advocacy. The Canadian Constitution and human rights legislation across Canada prohibits discrimination on the basis of gender and includes pregnancy and the possibility of becoming pregnant as a characteristic of gender. Some provinces note that breastfeeding is a characteristic of gender. Women's Wellness Within, a nonprofit organization providing volunteer perinatal support to criminalized women in Nova Scotia, conducted a scan of all provincial and territorial correctional services acts and the federal Corrections and Conditional Release Act: none mention breastfeeding. Protocols for breastfeeding during arrest and lockup by police were not available in any jurisdiction across Canada. International law, including the Convention on the Rights of the Child, the Nelson Mandela Rules, and the Bangkok Rules, have application to the rights of incarcerated breastfeeding women. The Inglis v. British Columbia (Minister of Public Safety) (2013) and Hidalgo v. New Mexico Department of Corrections (2017) decisions are pivotal examples of successful litigation brought forward by incarcerated mothers to advance breastfeeding rights. Improved application and understanding of existent law could advance breastfeeding rights.

Terrorism in South Korea.

Wang, Soon Joo; Choi, Jin Tae; Arnold, Jeffrey

2003-01-01

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.

The Stock Market and Macroeconomic Variables in a BRICS Country and Policy Implications

Directory of Open Access Journals (Sweden)

Yu Hsing

2011-01-01

Full Text Available This paper examines the effects of selected macroeconomic variables on the stock market index in South Africa. The exponential GARCH (Nelson, 1991 model is applied. It finds that South Africa’s stock market index is positively influenced by the growth rate of real GDP, the ratio of the money supply to GDP and the U.S. stock market index and negatively affected by the ratio of the government deficit to GDP, the domestic real interest rate, the nominal effective exchange rate, the domestic inflation rate, and the U.S. government bond yield. Therefore, to maintain a robust stock market, the authorities are expected to pursue economic growth, fiscal prudence, a higher ratio of the money supply to GDP, a lower real interest rate, depreciation of the rand, and/or a lower inflation rate.

Awareness and Use of South Asian Tobacco Products Among South Asians in New Jersey.

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.

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

South Africa comes clean

Albright, D.

1993-01-01

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

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.

Full Text Available This article aims to show an overview of the energy cooperation scheme called PETROCARIBE, proposed in 2005 by the Bolivarian Republic of Venezuela to the Caribbean and Central American countries. It argues that the emergence of this project, like other South-South cooperation initiatives, is clearly linked to several strategic foreign policy goals, which basically refer to geopolitical, economic, security and, last but not least, international solidarity parameters. The first section outlines some general characteristics of South-South cooperation and current trends and debates. The following presents the peculiar features of the Bolivarian foreign and energy policies. The next presents a general description of the PETROCARIBE framework, working mechanisms and its most important projects. Finally, after a discussion on PETROCARIBE as a South-South cooperation initiative, by highlighting its scopes, problems and vulnerabilities, some conclusions are drawn.

Full Text Available Rodrigues firmó el melodrama autobiográfico Minha Vida con el heterónimo Suzana Flag. La autoría enmascarada y la enunciación travestida de este texto naturalizan los efectos ideológicos de la historia de amor, pero también plantean -tal vez inintencionalmente- una crítica al proceso de subjetivación femenina implícito en ella y una parodia al resultante ideal de Mujer. El análisis de las características contradictorias de este texto ponen en evidencia las limitaciones de la categoría "literatura de mujeres", y señala la pertinencia de remplazarla con la de "escribir como mujer".Rodrigues signed his heteronym's name - Suzana Flag- on the autobiographical melodrama Minha Vida [My Life]. The masked authorship and the transvestite enunciation of this text naturalize the ideological effects of the love story, but also poses -perhaps unintentionally- a critical view of the related process of producing a feminine subjectivity and a parody of the resulting ideal of Woman. The analysis of the contradictory characteristics of this text reveals the limitations of the category of "women's literature" and suggests the pertinence of replacing it with that of "writing like (or as a woman".

Clinical neuropsychology in South Korea, albeit its relatively short history, has advanced dramatically. We review a brief history and current status of clinical neuropsychology in South Korea. The history, the educational pathway, the training pathway, the certification process, and careers in clinical neuropsychology in South Korea are reviewed. We have reviewed the neuropsychological services, including assessment and treatment, research on neurological and psychiatric populations, and neuropsychology education and the requirements related to education, training, and board examinations of those providing neuropsychological services in South Korea. We also describe how the Korean Society for Neuropsychology Research, the first and only meeting for neuropsychologists in the country established in 1999, has played a major role in how clinical neuropsychology is practiced and developed as a professional field in South Korea. Clinical neuropsychology in South Korea has achieved major progress over just a quarter of a century, and its future is promising in light of the increasing demand for neuropsychological services and advances in neuroscience in the country. Challenges that the community of clinical neuropsychologists are currently facing in South Korea, including formalizing neuropsychological curriculum and training programs and developing advanced credentialing procedures, are discussed.

Anaglyph, South America

Science.gov (United States)

2003-01-01

This anaglyph (stereoscopic view) of South America was generated with data from the Shuttle Radar Topography Mission (SRTM). It is best viewed at or near full resolution with anaglyph glasses. For this broad view the resolution of the data was first reduced to 30 arcseconds (about 928 meters north-south but variable east-west), matching the best previously existing global digital topographic data set called GTOPO30. The data were then resampled to a Mercator projection with approximately square pixels (about one kilometer, or 0.6 miles, on each side). Even at this decreased resolution the variety of landforms comprising the South American continent is readily apparent.Topographic relief in South America is dominated by the Andes Mountains, which extend all along the Pacific Coast. These mountains are created primarily by the convergence of the Nazca and South American tectonic plates. The Nazca Plate, which underlies the eastern Pacific Ocean, slides under western South America resulting in crustal thickening, uplift, and volcanism. Another zone of plate convergence occurs along the northwestern coast of South America where the Caribbean Plate also slides under the South American Plate and forms the northeastern extension of the Andes Mountains.East of the Andes, much of northern South America drains into the Amazon River, the world's largest river in terms of both watershed area and flow volume. Topographic relief is very low in much of the Amazon Basin but SRTM data provide an excellent detailed look at the basin's three-dimensional drainage pattern, including the geologic structural trough (syncline) that hosts the eastern river channel.North of the Amazon, the Guiana Highlands commonly stand in sharp contrast to the surrounding lowlands, indeed hosting the world's tallest waterfall, Angel Falls (979 meters or 3212 feet). Folded and fractured bedrock structures are distinctive in the topographic pattern.South of the Amazon, the Brazilian Highlands show a mix of

"TB is too often a death sentence. It does not have to be this way,"- Nelson Mandela. Despite the success of anti-mycobacterial drugs over the past 70 years, mycobacterial disease, particularly tuberculosis is still responsible for millions of annual deaths worldwide. Additionally, the emergence of Multidrug Resistant (MDR-TB) and Extensively Drug Resistant (XDR-TB) Tuberculosis has motivated calls by the World Health Organization (WHO) for novel drugs, vaccines and diagnostic tests. Consequently, the identification and evaluation of a range of anti-mycobacterial compounds against pathogenic mycobacterial species is of paramount importance. My colleagues and I at Cork Institute of Technology (CIT) and University College Cork (UCC) have tackled this issue through the initial optimization of the rapid, robust and inexpensive microtitre alamarBlue assay (MABA) and subsequent employment of this assay to facilitate the rapid assessment of a new wave of potential therapeutic compounds, namely bacteriocins, in particular type 1 bacteriocins known as lantibiotics. The gene encoded nature of these peptides facilitates their genetic manipulation and consequent activities as anti-microbial agents. In this regard, it may be possible to one day develop diverse populations of anti-mycobacterial bacteriocins with species specific activities. This may in turn provide more targeted therapies, resulting in less side effects, shorter treatment times and thus better patient compliance. Although current drug regimes are effective in the interim, previous lessons have taught us not to be complacent. In the words of the Intel founder Andrew Grove, 'Success breeds complacency. Complacency breeds failure. Only the paranoid survive'. Armed with knowledge of previous failures, it is the duty of the scientific community to anticipate future bacterial resistance and have an arsenal of compounds standing by in such an eventuality.
