    Full Text Available The primary motivation for this research, in which a qualitative method was employed, was to examine political apathy amongst students at Nelson Mandela Metropolitan University. The secondary motivation was to question whether youth political apathy threatens the consolidation of democracy. The researchers arranged four focus groups at Nelson Mandela Metropolitan University. A purposive sampling technique was utilised. All 50 participants in the study were Nelson Mandela Metropolitan University undergraduate and postgraduate black students, with ages ranging from 21 to 35 years. The researchers encouraged participants to have maximum participation in the focus group deliberations. The researchers also made use of elite interviews in the study. The findings of this study suggest that political apathy does exist amongst students at Nelson Mandela Metropolitan University. Most of the participants in the focus groups indicated that young people in post-apartheid South Africa have no interest in politics.

    In this article, I reflect on Nelson Mandela's (Madiba, the clan name of Mandela) education legacy. I argue that Madiba's education legacy is constituted by three interrelated aspects: firstly, an education for non-violence guided by deliberation, compassion and reconciliation; secondly, education as responsibility towards the Other; and thirdly,…

    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

    Full Text Available Nelson Mandela dedicated his life to fighting for the freedom of his South African kin of all colors against the institution of apartheid. He spent twenty-seven years fighting from within prison, only gaining his freedom when his fellow South Africans could claim it as well. This article demonstrates how his faith, his spiritual development and his noble purpose can be conceptualized through the lens of Ubuntu: the African ethic of community, unity, humanity and harmony.

    Full Text Available For many reasons, reflecting on the life of Nelson Mandela is a precarious exercise. If Mandela is a symbol of the resilience of the human spirit under trying conditions, he is also a symbol that is appropriated in various ways – helpful and unhelpful – by various people. This article explores some of the unhelpful ways in which the name and person of Nelson Mandela is invoked. In particular, the article looks at the hagiographical orientation of several reflections on Mandela, cautioning how some of these may have an effect less noble than originally intended. Accordingly, the article asks: How much can the symbol of Mandela bear? How much more can Mandela give? The logic and rationale of Mandela hagiography is explored. Following his death, there has been an explosion of interest in the life and symbol that is Nelson Mandela. Mandela literature, including multi-media, is on the rise. If the symbol of Mandela is in danger of being ‘cannibalised’, there is also a danger of relegating Mandela to an ahistorical mythical figure. The solution lies in at least two area, namely, the increment of alternative Mandela narratives and the introduction of more critical Mandela narratives. In this regard, Mandela’s own self-understanding as captured in his reflections about his life offer several clues which are explored in this article.

  13. Nelson Mandela's defence: A psychological capital documentary analysis

    Directory of Open Access Journals (Sweden)

    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.

  14. Adolescent and young pregnant women at increased risk of mother-to-child transmission of HIV and poorer maternal and infant health outcomes: A cohort study at public facilities in the Nelson Mandela Bay Metropolitan district, Eastern Cape, South Africa.

    2014-12-01

    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

  16. Fathers of the Nation: Barack Obama Addresses Nelson Mandela

    Directory of Open Access Journals (Sweden)

    Elisa Bordin

    2014-11-01

    Full Text Available This essay analyzes Barack Obama’s Nelson Mandela Memorial speech together with other seminal texts of Obama’s political and personal creed, such as his book Dreams from My Father (1995 and his speech “A More Perfect Union” (2008. This reading becomes helpful to understand Mandela’s transnational power, which Obama uses to comment on the United States by comparing Madiba to other American “fathers of the nation.” Thus, he uproots Mandela’s from a specifically South African legacy, expands his figure, and addresses him as a transnational father of his own nation, whose power, influence, and example transcend South African borders. As a consequence of this enlargement and transnational validation of Mandela’s figure, the speech delivered at the Memorial becomes an occasion to tackle American past and future, while the memory of Madiba and his driving example in Obama’s life serve to reinforce previous positions conveyed in other discourses by the American President, such as the “A More Perfect Union” speech delivered in Philadelphia in 2008.

    2011-01-01

    This paper explores the political, economic, and social life of Nelson Mandela through his food choices from 1918 to the present. A description of the minutiae of one particular 1950s Sunday lunch is used to examine the broader role of first colonial and later apartheid legislation in determining the dietary choices and options of South Africans past and present. How such policies shaped attitudes and access to Nelson Mandela’s ancestral Xhosa cuisine is assessed. The long-term cultural, economic, and political impact of a lack of access to core indigenous African ingredients is evaluated. Most of all this paper offers a snapshot portrayal of two families (one white, one black) trying to sustain a normal friendship within a grossly abnormal society.

    Shortly after the conviction of Nelson Mandela at the Rivonia trial in 1964, the Anti-Apartheid Movement of Geneva was created at a meeting at CERN. Arriving at CERN as Visiting Scientist in June 1966, I joined the Anti-Apartheid Movement immediately. We multiplied the initiatives at CERN and outside of CERN until the release of Mandela with citizens of Geneva, but also with "citizens of the world", who ignored the ban on political activity, particularly for international civil servants. The Anti-Apartheid Movement of Geneva soon became the Anti-Apartheid Movement of Switzerland. It was also the first Anti-Apartheid Movement outside of South Africa. CERN today is honoured to have brought it to the baptismal font thanks to the initiative of several colleagues, including Mike Pentz, president of the CERN staff Association for two years (1961  1963) and also a refugee from South Africa in Europe. Conclusion: well-targeted disobedience can advance humanity. Jean-Pierre Lagnaux, former vis...

  3. 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.

    At this time in history, I consider myself very privileged to have spent some three hours in the presence of President Nelson Mandela as a Howard University faculty member in the late 1990s. Then, President of Howard University, H. Patrick Swygert bestowed upon President Nelson Mandela, Esquire an Honorary Doctorate of Human Letters. I can only equate this experience to my four mile walk up the Bedaling Wall (Great Wall) in China (a magnificent ancient wonder of the world), and trying to relate this event to something only fortunate souls have had the chance to enjoy. I also treasure the once in a lifetime visit to the Republic of South Africa in 1998 when the Association of Black Nursing Faculty, Inc., Chi Eta Phi Nursing Sorority, Inc., and the Department of Nursing (University of Botswana) sponsored the trip as an attempt to establish partnerships, share common interests and discussion in how to meet health needs of emerging majority and disadvantaged populations in the world, including mainly, the continent of Africa, in the 21st century. This short memoir can only piggy-back the massive coverage in the media that began almost instantly as a long anticipated event (death of Nelson Mandela), but startled upon its occurrence.

    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.

  7. Provision of antiretroviral therapy for children in Nelson Mandela Bay: Health care professionals’ challenges

    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.

    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.

    2017-07-01

    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.

    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

    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.

    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.

    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.

    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.

    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.

    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.

    Intracranial suppuration (ICS) is a life-threatening condition caused by various disease processes and consisting of brain abscess and extradural and subdural empyema. The major causes have changed over the decades. To the author's knowledge, the incidence of ICS in South Africa (SA) has not been established. To determine the incidence of ICS, overall and according to age and gender, and to identify the source and distribution of ICS. 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.

    Full Text Available Uma pesquisa Intensiva com os usuários finais no setor da Habitação Econômica da República Sul-Africana tornou-se necessário para encontrar formas de enfrentar o contínuo aumento dos custos e ainda continuar a satisfazer as preferências, com qualidade e acessibilidade. A pesquisa tem de ser sucedida por projetos inovadores e métodos construtivos rápidos e de baixo custo, sem perder qualidade e estética. Os custos de terreno e o adensamento dos projetos, em equilíbrio com a qualidade ambiental, tornaram-se de enorme importância em qualquer empreendimento sustentável. O mesmo se aplica às vizinhanças, quanto à revitalização dos bairros. 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.

    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.

  13. 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.

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

    Directory of Open Access Journals (Sweden)

    Shireen Hassim

    2015-03-01

    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.

  19. Red Mandela: Contests of auto-biography and Auto/biography in South Africa

    Directory of Open Access Journals (Sweden)

    Ciraj Rassool

    Full Text Available This article examines the case of the red Mercedes-Benz built in 1990 by workers at the Mercedes-Benz plant in East London and presented to Nelson Mandela as a gift shortly after his release from prison. During the 1990s a biographic order marked by a discourse of heroic leaders was growing in South Africa, where biographic narration and self-narration played a noticeable and, at times, substantial part in political transformation and reconstruction. Nelson Mandela's 'long walk to freedom' became the key trope for South Africa's history, narrated as the triumph of reconciliation. The presentation of the car to Nelson Mandela in 1990 occurred at a time of transition in the life of his auto/biography, from the biography of desire for the absent revolutionary leader to the biography of a statesman and president. This partly explains the ambiguous, double-edged history of the gift, as a labour of love on the part of NUMSA workers and as donation by Mercedes-Benz South Africa (the corporate version of these events emphasised the 'friendship' that was 'sparked' between Nelson Mandela and Mercedes-Benz South Africa. Inspired by the East London autoworkers' commitment to produce the car for Mandela, as well as by the resilience some of them showed during their nine-week strike and sleep-in in the plant soon afterwards, Simon Gush's installation Red has intervened in how those events should be remembered. By choosing to exhibit the disassembled body panels of a replica car alongside reconstructed displays of sleep-in strike beds made of scaffolding, foam, upholstery and car headrests, with imagined uniforms of striking workers, Gush has chosen to appropriate the history of the events of 1990 from the celebratory frames of the Mandela biographic order. The installation turns into an inquiry into the labour process and the events of the strike that was critical of the reconciliatory and celebratory understanding of the gift as a product of a partnership

    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.

  5. 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

    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

  8. Nelson syndrome: definition and management.

    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.

    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.

    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).

    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.

    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.)

    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.)

  18. 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 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.

    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

    2015-06-01

    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.

  16. 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.

    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.

    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.

    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.

  2. On the domain of the Nelson Hamiltonian

    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.

    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.

    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.

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

    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.

  13. 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

    Directory of Open Access Journals (Sweden)

    D McQuoid-Mason

    2017-11-01

    Full Text Available 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

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

    International Nuclear Information System (INIS)

    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.

    1983-01-01

    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).

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

    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

    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.).

    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.

    Full Text Available Over the past 30 years Calgary has doubled in size, from a population of 640,645 in 1985 to 1,230,915 in 2015. During that time the City has had five different mayors, hosted the Winter Olympics, and expanded the C-Train from 25 platforms to 45. Calgary’s Metropolitan Area has grown too, with Airdrie, Chestermere, Okotoks and Cochrane growing into full-fledged cities, ripe with inter-urban commuters.* And with changes to provincial legislation in the mid-’90s, rural Rocky View County and the Municipal District of Foothills are now real competitors for residential, commercial and industrial development that in the past would have been considered urban. In this metropolitan system, where people live, their household structure, and their place of work informs the services they need to conduct their daily lives, and directly impacts the spatial character of the City and the broader region. In sum, Metropolitan Calgary is increasingly complex. Calgary and the broader metropolitan area will continue to grow, even with the current economic slowdown. Frictions within Calgary, between the various municipalities in the metropolitan area, and the priorities of other local authorities (such as the School Boards and Alberta Health Services will continue to impact the agendas of local politicians and their ability to answer to the needs of their residents. How resources – whether it is hard infrastructure, affordable housing, classrooms, or hospital beds – are allocated over space and how these resources are funded, directly impacts these relationships. This technical paper provides my perspective as an urban economist on the efficient allocation of resources within a metropolitan system in general, with reference to Calgary where appropriate, and serves as a companion to the previously released “Reflections on Calgary’s Spatial Structure: An Urban Economists Critique of Municipal Planning in Calgary.” It is hoped that the concepts reviewed

    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.

  3. 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.

    Full Text Available Capitals gather constellations of bright and creative people, attracting them from the peripheries. Tchekhov’s sisters were anxious to get to Moscow, d’Artagnan – to Paris. Evtushenko, Shukshin and Gaidai ascended to the climax of their glory, having moved to the capital. Vampilov, Rasputin and Astafiev became internationally famous without leaving their home grounds, but having joined in the metropolitan whirl. In this regard, the architectural profession differs greatly from the literary and cinematographic ones. The destinies of the masters who fulfilled themselves far from the capital are different but equally bright and unique. The Irkutsk “Varangians”of the sixtieth – Voronezhsky, Bukh and Pavlov – built up their relations with geography in a different way:someone came from the capitals just for a few years that became the brightest, the most fruitful and the most interesting years of his creative life. But someone stayed in the non-metropolitan city for a long time and even forever. This subsection contains certain examples of self-fulfillment in the cities distant from the capitals: Khabarovsk, Irkutsk, Bratsk, Krasnoyarsk, Kemerovo and Anzhero-Sudzhensk.

  13. 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

  14. Metropolitan Lima: area profile.

    Science.gov (United States)

    Hakkert, R

    1986-11-01

    This profile of metropolitan Lima, Peru, covers administrative divisions; population growth; age distribution; ethnicity and religion; housing and households; education and health care; economic activity, income, and consumption; transport and communication; and sources of information. Nearly 30% of Peru's entire population and 42% of its urban population live in Lima. The trend continues, yet Lima's urban primacy is waning due to the growth of some regional centers like Trujillo and Chimbote. Lima is still almost 10 times as large as the country's next ranking cities, Trujillo on the northern coast and Arequipa in the south. Peru's main administrative divisions are the 24 departments, of which the Department of Lima is one. These departments are further divided into 156 provinces. Greater Lima consists of 2 such provinces, the province of Lima and the constitutional province of Callao. Although the population of Lima continues to grow, its rate of growth slowed from about 5.5% during the 1960s to about 3.9% in the 1970s. Current projections estimate a metropolitan population of 6.7 million by 1990. On the whole, Lima's age structure is somewhat older than that of the rest of Peru. The median age of the population is 22.3 years, compared to a national figure of 20.4. The proportion of persons over age 65 is only 3.6%, lower than the national average of 4.1%, due to the tendency of in-migration to concentrate people of intermediate ages in the cities. Almost 400,000 inhabitants of greater Lima are bilingual in Spanish and an indigenous language. As elsewhere in Peru, the dominant religion is Roman Catholicism. Lima is a spread out city with few high rise buildings due to the danger of earthquakes. Only 12% of Lima's households are found in apartment buildings. As in other cities of Latin America, the formal housing market is beyond the reach of a major segment of the population. Consequently, much of the urban settlement has occurred through informal self

    To canvas perceptions and experiences of students who had failed Year 2 of a traditional medical program and who chose to remain in the conventional program (n = 6) or had swapped to Curriculum 2001 (C2001), a problem-based learning (PBL) curriculum (n = 14). A year after their decision regarding curriculum choice, students were canvassed (largely open-ended survey) about this decision and about their perceptions of their curricular experiences. C2001 students were positive about their PBL experiences. Overwhelmingly, their decision to swap streams had been a good one. They identified PBL features as supporting their learning. Repeating traditional curriculum students were, however, more circumspect in their opinions. C2001 students had clearly embraced PBL. They were now medical students, largely because of PBL activities underpinned by a sound educational philosophy. This unique case study has provided additional evidence that PBL students are generally more content with their studies than their conventional curriculum counterparts.

  1. Metropolitan City: the Italian experience

    Directory of Open Access Journals (Sweden)

    Giuseppe Franco Ferrari

    2013-12-01

    Full Text Available Due to the fact that the definitions of territorial organization are no longer adequate, the concept of “metropolitan areas” arises as a solution to resolve such deficit. This study shows the beginnings of this figure in Italy and the problems of identification and delimitation caused by the abstraction of the norms, therefore entailing a difficult implementation of the concept of metropolitan cities. By identifying these obstacles, this paper presents an analysis where it is possible to ensure compliance with this new reality in the near future.

    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

  18. 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.

    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)

    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.)

    2014-03-01

    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.

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

    Sainsbury, C.J.

    1952-01-01

    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.

  3. Premises for Shaping Metropolitan Areas in Romania

    Directory of Open Access Journals (Sweden)

    RAULARIAN RUSU

    2012-01-01

    Full Text Available The setting up of metropolitan areas is a process which is still in progress in Romania. The legislative framework for the creation of these areas has been built up only since 2001, and there are still a number of juridical inconsistencies concerning the association of administrative units to form metropolitan areas. On the other hand, political reasons and the fear of losing a certain degree of authority and to become subordinates of the large cities (in the case of rural municipalities also hindered the development of metropolitan areas in Romania. Nevertheless, the metropolitan areas already in existence are running a number of projects that are beneficial for most members of the association. Such positive examples may trigger the creation of the other metropolitan areas. Although the existing metropolitan areas did not yield spectacular results, the time passed since their foundation is yet too short to correctly assess their usefulness and territorial meaning. For the moment, the following metropolitan areas exist in Romania: Iaşi, Oradea, Braşov, Constanţa, Bacău, Cluj-Napoca, Târgu Mureş and Craiova. Bucharest, Timişoara, Ploieşti and Galaţi-Brăila metropolitan areas are still in process of setting up.

    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

    Glacial and fluvioglacial landforms and deposits preserved in the middle reaches of the Maruia valley, southeast Nelson, New Zealand, record the activity of the Maruia glacier during the late Pleistocene Otira Glaciation. Five advances are recognised, from oldest to youngest: Creighton 1, 2, 3, and the Reid Stream 1, 2 advances. There was an interstadial interval between the Creighton 3 and Reid Stream 1 advances. The Reid Stream 1 advance occurred shortly after 14 800 years B.P. (NZ536, old T/sub 0.5/). (auths)

    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...

    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.

    Kuzmichev, N.D.; Vasyutin, M.A.; Golovashkin, A.I.

    2007-01-01

    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

    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

  16. Broadband availability in metropolitan and non-metropolitan Pennsylvania

    Lawrence E. Wood

    2016-09-01

    Full Text Available Over the past few years having a broadband connection has become essential for many Internet activities. As broadband increases in importance, it becomes imperative to assess how its use and availability may vary, especially in relation to issues such as geographic location. For rural areas in particular, the availability of broadband service is especially important. This research assesses broadband service availability in rural areas of Pennsylvania, USA. In particular, it examines the extent to which Digital Subscriber Line (DSL and broadband cable modem services are being deployed throughout rural Pennsylvania. It compares this deployment with the availability of such services in the state’s urban and metropolitan areas. The results of this research suggest that there is a “digital divide” in terms of broadband availability between rural and urban areas of Pennsylvania. However, this “divide” is perhaps not as wide as might be expected. Thus, as broadband is becoming increasingly available in rural areas of the U.S. and throughout much of the rest of the world, this research concludes that while research must remain vigilant in terms of assessing advanced telecommunications availability in rural areas, future research should also be sure to focus on how such technologies can be used to promote economic and social concerns, including in relation to building online networks and diminishing social and professional isolation in rural areas.

  17. 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.

    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

    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.

    1990-01-01

    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

    2012-01-01

    Because poverty in rural and urban areas of the US often has different causes, correlates and solutions, effective anti-poverty policies depend on a thorough understanding of the ruralness or urbanness of specific places. This paper compares several widely used classification schemes and the varying magnitudes of poverty that they reveal in the US. The commonly used ‘metropolitan/non-metropolitan’ distinction obscures important socioeconomic differences among metropolitan areas, making our understanding of the geography of poverty imprecise. Given the number and concentration of poor people living in mixed-rural and rural counties in metropolitan regions, researchers and policy-makers need to pay more nuanced attention to the opportunities and constraints such individuals face. A cross-classification of the Office of Management and Budget’s metro system with a nuanced RUDC scheme is the most effective for revealing the geographical complexities of poverty within metropolitan areas.

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

    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

    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.

    Full Text Available Various parts of sea buckthorn [Elaeagnus rhamnoides (L. A. 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.

    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)

    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.

    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.

    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.

    Different from Taipei, the metropolitan Kaohsiung which is a coastal and industrial city has the major pollution sources from stationary sources such as coal-fired power plants, petrochemical facilities and steel plants, rather than mobile sources. This study was an attempt to conduct a comprehensive and systematical examination of the holiday effect, defined as the difference in air pollutant concentrations between holiday and non-holiday periods, over the Kaohsiung metropolitan area. We documented evidence of a "holiday effect", where concentrations of NOx, CO, NMHC, SO2 and PM10 were significantly different between holidays and non-holidays, in the Kaohsiung metropolitan area from daily surface measurements of seven air quality monitoring stations of the Taiwan Environmental Protection Administration during the Chinese New Year (CNY) and non-Chinese New Year (NCNY) periods of 1994-2010. Concentrations of the five pollutants were lower in the CNY than in the NCNY period, however, that of O3 was higher in the CNY than in the NCNY period and had no holiday effect. The exclusion of the bad air quality day (PSI > 100) and the Lantern Festival Day showed no significant effects on the holiday effects of air pollutants. Ship transportation data of Kaohsiung Harbor Bureau showed a statistically significant difference in the CNY and NCNY period. This difference was consistent with those found in air pollutant concentrations of some industrial and general stations in coastal areas, implying the possible impact of traffic activity on the air quality of coastal areas. Holiday effects of air pollutants over the Taipei metropolitan area by Tan et al. (2009) are also compared.

    Sixty “Mega Cities” would emerge by 2015 catering of 600 million populations, and were threatened by the climate change, because of cyclones, flooding, etc. Jakarta became a metro region covering Jakarta, Bogor, Tangerang, Bekasi, Depok and Cianjur. Jakarta metropolitan faced the very high population growth, urban sprawling, traffic jams, flooding, green open space reduction, environmental degradation, urban slums and illegal street hawkers. Flooding and traffic congestions were the two most important issues to solve. SWOT analysis and urban design solutions were produced to create a sustainable solution. Related to transportation issues, Singapore Mass Rapid Transport (MRT) concept was evaluated. Meanwhile the Netherlands’ polder concept as well as Singapore’s Integrated Water Management were also analyzed. The development of above ground MRT as well as Busway could be developed to connect Jakarta Metropolitan Region. The networks were developed on the main toll road networks. The MRT and Busway would eventually replace the need of automobile use in the future. The Transit - Oriented - Development (TOD) with high density can be suggested to be concentrated nearby the MRT and Busway interchange stations. The Netherlands’ polder and were adopted for urban’ low-lying lands in Jakarta Metropolitan Region, A polder system was defined as the Integrated Man-made Drainage System consisting Dikes, Drains, Retention Ponds, Outfall Structures or Pumping Stations. The polder system was proposed to be extended to Tangerang and Bekasi area.

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

    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

    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

    The Helsinki Metropolitan Area Climate Change Adaptation Strategy has been prepared in close cooperation with the four cities of the metropolitan area (Helsinki, Espoo, Vantaa and Kauniainen), the Helsinki Region Environmental Services Authority HSY and other municipal, regional and state level organisations. In the strategy, strategic starting points and policies with which the metropolitan area prepares for the consequences of climate change, are compiled. The Helsinki Metropolitan Area adaptation strategy concentrates on the adaptation of the built and urban environment to the changing climate. The vision of the strategy is climate proof city - the future is built now. The strategy aims to (1) assess the impacts of climate change in the area, (2) prepare for the impacts of climate change and to extreme weather events and (3) to reduce the vulnerabilities of the area to climate variability and change. The target is to secure the well-being of the citizens and the functioning of the cities also in the changing climate conditions. The preparation of the adaptation strategy started in 2009 by producing the background studies. They include the regional climate and sea level scenarios, modelling of river floods in climate change conditions and a survey of climate change impacts in the region. Also, existing programmes, legislation, research and studies concerning adaptation were collected. The background studies are published in a report titled 'The Helsinki metropolitan area climate is changing - Adaptation strategy background studies' (in Finnish) (HSY 2010). HSY coordinated the strategy preparation. The work was carried out is close cooperation with the experts of the metropolitan area cities, regional emergency services, Ministry of the Environment, Helsinki Region Transport Authority and other regional organisations. The strategy work has had a steering group that consists of representatives of the cities and other central cooperation partners. The

    2014-12-01

    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

    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

    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

    This first report describes the present makeup of the Las Vegas metropolitan statistical area (MSA) economy and analyzes the climate for business expansion. The second report contains an assessment of the competitiveness of the area as a location for new or expanded facilities investment by companies in approximately 600 business groups. The third report projects Las Vegas' competitiveness at the start of the next century in the absence of a nuclear waste storage facility and then evaluates the potential impacts of siting that facility near Las Vegas on its ability to attract and retain business investment. The primary purpose of these reports is to contribute to the overall assessment of the environmental impact of the US Department of Energy's proposed action to build and operate an underground nuclear waste storage facility at Yucca Mountain. The first two reports also serve a second purpose -- they can be used by economic development organizations in the Las Vegas metropolitan area in their ongoing efforts to attract new business investment. Information contained in the business climate analysis found in this first report can be incorporated into marketing materials. The competitiveness assessment contained in the second report can be used by these organizations in identifying targets they wish to pursue

    Full Text Available This research exercise aims to identify all areas affected by what is now known as ‘youthification’ in the Metropolitan Area of Cluj. Broadly speaking, an area touched by youthification witnesses a massive arrival of young adults, who invest in housing, but only remain there until they age. Youthification is usually the second phase within an encompassing process of gentrification. To gain a clearer picture of this phenomenon, we employed a snapshot of the situation recorded by the Population and Housing Census of 2011. Using this image as a starting point, we then applied statistical thresholds aimed at measuring the presence and intensity of youthification within different areas. Thereafter, we looked at areas exhibiting the same level of youthification, in order to find those common traits of their young adult inhabitants that might prove relevant for their choices in matters of housing. Once completed, our efforts resulted in the first map showing the areas affected by youthification within the Metropolitan Area of Cluj. In addition, we reached the following conclusion: Young adults who live in the city are more likely to still be enrolled in a form of education and less likely to be married or to have children than those who live in the suburbs or in rural areas. This observation implies that there might be some hidden dependency relations, which are at work in shaping the choice of housing.

    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.

    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...

    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

    The radon testing survey in Metropolitan Toronto public schools was the most intensive project of its kind ever undertaken in Canadian schools. It also included an extensive public education program on radiation and radon-in-schools. The radon levels at 632 schools were measured using the CAIRS Radon Monitors. Ninety percent of the locations measured were found to have a radon level equal to or less than 2 mWL. Two locations in two different schools were found to have a radon level at or above the Action Level (20 mWL). The remaining results were between the two extremes. Follow-up testing in those schools where more than 10 mWL of radon was found is in progress. (author)

    2011-01-01

    Although Soviet-era urban-growth controls produced relatively sustainable metropolitan development patterns, low-density suburban sprawl has accelerated markedly in modern Russia. Distinctive features of Moscow's development history are its greenbelt, which dates from 1935 and is becoming increasingly fragmented, proliferation of satellite cities at the urban fringe, conversion of seasonal dachas into full-time residences, the very exclusive Rublevo Uspenskoe Highway development, and today's crippling traffic congestion. The recent economic crisis has slowed development and actually increased the supply of “economy-class” single-family homes, for which there is much pent-up desire but insufficient credit availability to meet the demand. A renewed commitment to sustainability's triple bottom line—environmental quality, equity, and economic prosperity—will require greater government transparency and fairness, stronger planning controls, and an expanded public transportation system.

  17. Metropolitan migration and population growth in selected developing countries.

    Science.gov (United States)

    1983-01-01

    The purpose of this article is to estimate the components of metropolitan population growth in selected developing countries during 1960-1970 period. The study examines population growth in 26 cities: 5 are in Africa, 8 in Asia, and 13 in Latin America, using data from national census publications. These cities in general are the political capitals of their countries, but some additional large cities were selected in Brazil, Mexico, and South Africa. All cities, at the beginning of the 1960-1970 decade had over 500,000 population; Accra, the only exception, reached this population level during the 1960s. Some cities had over 4 million residents in 1970. Net migration contributed about 37% to total metropolitan population growth; the remainder of the growth is attributable to natural increase. Migration has a much stronger impact on metropolitan growth than suggested by the above figure: 1) Several metropolitan areas, for various reasons, are unlikely to receive many migrants; without those cities, the share of metropolitan growth from net migration is 44%. 2) Estimates of the natural increase of migrants after their arrival in the metropolitan areas, when added to migration itself, changes the total contribution of migration to 49% in some metropolitan areas. 3) Even where net migration contributes a smaller proportion to metropolitan growth than natural increase, the rates of net migration are generally high and should be viewed in the context of rapid metropolitan population growth from natural increase alone. Finally, the paper also compares the components of metropolitan growth with the components of growth in the remaining urban areas. The results show that the metropolitan areas, in general, grow faster than the remaining urban areas, and that this more rapid growth is mostly due to a higher rate of net migration. Given the significance of migration for metropolitan growth, further investigations of the effects of these migration streams, particularly with

    2018-02-01

    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.

    Understanding of the mechanisms driving our daily face-to-face encounters is still limited; the field lacks large-scale datasets describing both individual behaviors and their collective interactions. However, here, with the help of travel smart card data, we uncover such encounter mechanisms and structures by constructing a time-resolved in-vehicle social encounter network on public buses in a city (about 5 million residents). Using a population scale dataset, we find physical encounters display reproducible temporal patterns, indicating that repeated encounters are regular and identical. On an individual scale, we find that collective regularities dominate distinct encounters' bounded nature. An individual's encounter capability is rooted in his/her daily behavioral regularity, explaining the emergence of "familiar strangers" in daily life. Strikingly, we find individuals with repeated encounters are not grouped into small communities, but become strongly connected over time, resulting in a large, but imperceptible, small-world contact network or "structure of co-presence" across the whole metropolitan area. Revealing the encounter pattern and identifying this large-scale contact network are crucial to understanding the dynamics in patterns of social acquaintances, collective human behaviors, and--particularly--disclosing the impact of human behavior on various diffusion/spreading processes.

    Full Text Available The last stage of the process of establishment of the Italian Metropolitan Cities, which took place in 2014, follows of a few decades the start of this institutional reform. In 1990, in fact, the Act 142 (Local Autonomies Reform had planned metropolitan areas as the administrative organization more suitable to provide these territories of structures for the management and the strategic development alike the best international models. The paper proposes to analyse the first activities taken by the Italian Metropolitan Cities in the sector of territorial government, three years after the enactment in 2014 of Act nr. 56.  Focal point of the analysis is the jurisdiction in the formation of two plans (the Strategic Plan and the Metropolitan Territorial Plan and the following relationships among them, in the logical assumption that between them a necessary and strict consistency there should be. In the first part, the paper analyses some factors characterizing the metropolitan areas and the functions that the law assigns to the new institution in the territorial government sector. The second part outlines the updated situation with regard to the formation of the sectoral tools (Strategic Plan, Territorial Plan and homogeneous zones. The third part analyses the progresses in three Metropolitan Cities taken as sample (Milan, Genoa and Bologna and, in general, to those of Southern Italy. In the last part, the paper exposes some considerations regarding the issues raised in the article, particularly about the innovativeness of the tools and the timeline for the implementation of the act.

    Full Text Available Carbon neutrality represents one climate strategy adopted by many cities, including the city of Helsinki and the Helsinki metropolitan area in Finland. This study examines initiatives adopted by the Helsinki metropolitan area aimed at reducing energy-related carbon emissions and achieving carbon neutrality through future actions. Various sectorial energy consumption rates per year and carbon emissions from various sectors within the city of Helsinki and the metropolitan area were extracted from an online database and re-calculated (in GWh, MWh/inhabitant and MtCO2e, KtCO2e/inhabitant. We employed a backcasting scenario method to explore the various carbon reduction measures in the Helsinki metropolitan area. About 96% of the emissions produced in the Helsinki metropolitan area are energy-based. District heating represents the primary source of emissions, followed by transportation and electricity consumption, respectively. We also found that accomplishing the carbon reduction strategies of the Helsinki metropolitan area by 2050 remains challenging. Technological advancement for clean and renewable energy sources, smart policies and raising awareness resulting in behavioral changes greatly affect carbon reduction actions. Thus, strong political commitments are also required to formulate and implement stringent climate actions.

    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

  7. Internal audit risk management in metropolitan municipalities

    2016-07-01

    Full Text Available Internal audit functions (IAFs of organisations are regarded as crucial components of the combined assurance model, alongside the audit committee, management and external auditors. The combined assurance model aims at having integrated and aligned assurance in organisations with the overall aim of maximising risk and governance oversight and control efficiencies. In this regard, internal audit plays a crucial role, insofar as it consists of experts in risk, governance and control consultancy who provide assurance to senior management and the audit committee. Audit committees are dependent on internal audit for information and their effectiveness revolves around a strong and well-resourced internal audit function which is able to aid audit committees to meet their oversight responsibilities. There is thus a growing demand for managing risk through the process of risk management and internal audit is in a perfect position to assist with the improvement of such processes. If internal auditors wish to continue being an important aspect of the combined assurance model, they need to address the critical area, amongst others, of risk management as part of their work. If not, it follows that the board, audit committees and other levels of management will remain uninformed on the status of these matters which, in turn, will negatively impact the ability of these stakeholders to discharge their responsibilities. This study therefore focuses on analysing the functioning of IAFs, with specific reference to their risk management mandate. The study followed a mixed method approach to describe internal audits risk management functioning in the big eight metropolitan municipalities in South Africa. The results show that internal audit provide a broad scope of risk management work which assist senior management in the discharge of their responsibilities. However, in the public eye, internal audits risk management functioning is scant

    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.

    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

  5. The food environment and adult obesity in US metropolitan areas.

    Science.gov (United States)

    Michimi, Akihiko; Wimberly, Michael C

    2015-11-26

    This research examines the larger-scale associations between obesity and food environments in metropolitan areas in the United States (US). The US Census County Business Patterns dataset for 2011 was used to construct various indices of food environments for selected metropolitan areas. The numbers of employees engaged in supermarkets, convenience stores, full service restaurants, fast food restaurants, and snack/coffee shops were standardised using the location quotients, and factor analysis was used to produce two uncorrelated factors measuring food environments. Data on obesity were obtained from the 2011 Behavioral Risk Factor Surveillance System. Individual level obesity measures were linked to the metropolitan area level food environment factors. Models were fitted using generalised estimating equations to control for metropolitan area level intra-correlation and individual level sociodemographic characteristics. It was found that adults residing in cities with a large share of supermarket and full-service restaurant workers were less likely to be obese, while adults residing in cities with a large share of convenience store and fast food restaurant workers were more likely to be obese. Supermarkets and full-service restaurant workers are concentrated in the Northeast and West of the US, where obesity prevalence is relatively lower, while convenience stores and fast-food restaurant workers are concentrated in the South and Midwest, where obesity prevalence is relatively higher. The food environment landscapes measured at the metropolitan area level explain the continental-scale patterns of obesity prevalence. The types of food that are readily available and widely served may translate into obesity disparities across metropolitan areas.

  11. New Metropolitan Spaces and Metropolitan Strategies in the Face of Modernisation

    Directory of Open Access Journals (Sweden)

    Willem Salet

    2007-10-01

    Full Text Available Au début du xxie siècle, les espaces urbains traversent une période de croissance et de transformation radicale. Les villes s’étendent de plus en plus. Leur configuration spatiale devient de plus en plus décentralisée et fragmentée. La dichotomie traditionnelle entre hiérarchie urbaine et périphérie est en train de disparaître. Les nouveaux espaces métropolitains sont caractérisés par des processus de segmentation et de spécialisation à distance ainsi que par des polarisations sociales qui structurent l’espace. Les tentatives de planification des villes-régions essaient de rééquilibrer ces processus qui font éclater la ville. Cet article explore brièvement les transformations métropolitaines actuelles en utilisant une approche générique. Il se focalise également sur les stratégies des métropoles pour affronter ces défis dans le cadre de situations institutionnelles variées, un peu partout en Europe. En troisième lieu, cet article interroge les effets potentiels des projets urbains sur un rééquilibrage des transformations urbaines. Comment les grands projets urbains sont-ils conceptuellement élaborés ? Comment les alliances d’acteurs qui les soutiennent se forgent-elles ? Comment les citoyens et les groupes sociaux sont-ils impliqués de manière à produire de nouveaux espaces plus intégrés ?At the beginning of the 21st century, urban spaces can be said to be in a stage of growth and radical transformation. Cities are highly expansive, both in scale and scope. The spatial configuration of urban spaces is, however, becoming more and more decentralised and fragmentary. The traditional dichotomy between urban hierarchy and periphery is disappearing. New metropolitan spaces are characterised by distance related processes of social and economic specialisation and segmentation, and often also by splitting social polarisation. The planning agendas in city regions are trying to make add more balance to the

  12. 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)

  13. Implications of urban structure on carbon consumption in metropolitan areas

    International Nuclear Information System (INIS)

    Heinonen, Jukka; Junnila, Seppo

    2011-01-01

    Urban structure influences directly or indirectly the majority of all green house gas (GHG) emissions in cities. The prevailing belief is that dense metropolitan areas produce less carbon emissions on a per capita basis than less dense surrounding rural areas. Consequently, density targets have a major role in low-carbon urban developments. However, based on the results of this study, the connection seems unclear or even nonexistent when comprehensive evaluation is made. In this letter, we propose a hybrid life cycle assessment (LCA) method for calculating the consumption-based carbon footprints in metropolitan areas, i.e. carbon consumption, with the emphasis on urban structures. The method is input-output-based hybrid LCA, which operates with the existing data from the region. The study is conducted by performing an analysis of the carbon consumption in two metropolitan areas in Finland, including 11 cities. Both areas consist of a dense city core and a less dense surrounding suburban area. The paper will illustrate that the influence of urban density on carbon emissions is insignificant in the selected metropolitan areas. In addition, the utilized consumption-based method links the climate effects of city-level development to the global production of emissions.

    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).

    Hirano, J.; Dairaku, K.

    2013-12-01

    Flood is one of the most significant natural hazards in Japan. The Tokyo metropolitan area has been affected by several large flood disasters. Therefore, investigating potential flood risk in Tokyo metropolitan area is important for development of adaptation strategy for future climate change. We aim to develop a method for evaluating flood risk in Tokyo Metropolitan area by considering effect of historical land use and land cover change, socio-economic change, and climatic change. Ministry of land, infrastructure, transport and tourism in Japan published 'Statistics of flood', which contains data for flood causes, number of damaged houses, area of wetted surface, and total amount of damage for each flood at small municipal level. By using these flood data, we estimated damage by inundation inside a levee for each prefecture based on a statistical method. On the basis of estimated damage, we developed flood risk curves in the Tokyo metropolitan area, representing relationship between damage and exceedance probability of flood for the period 1976-2008 for each prefecture. Based on the flood risk curve, we attempted evaluate potential flood risk in the Tokyo metropolitan area and clarify the cause for regional difference of flood risk. By analyzing flood risk curves, we found out regional differences of flood risk. We identified high flood risk in Tokyo and Saitama prefecture. On the other hand, flood risk was relatively low in Ibaraki and Chiba prefecture. We found that these regional differences of flood risk can be attributed to spatial distribution of entire property value and ratio of damaged housing units in each prefecture.We also attempted to evaluate influence of climate change on potential flood risk by considering variation of precipitation amount and precipitation intensity in the Tokyo metropolitan area. Results shows that we can evaluate potential impact of precipitation change on flood risk with high accuracy by using our methodology. Acknowledgments

  10. ELECTRICITY DEMAND IN A NORTHERN MEXICO METROPOLITAN ECONOMY

    Directory of Open Access Journals (Sweden)

    Thomas M. Fullerton

    2014-10-01

    Full Text Available Using an error correction framework, this study analyzes the long- and short-run dynamics of electricity demand in Ciudad Juarez, a large metropolitan economy on Mexico’s northern border. Demand is decomposed into the total number of electricity accounts and electricity usage per customer, each of which is modeled separately. A two-stage least squares approach is used to estimate the per customer electricity demand equations due to the endogeneity of the average price variable. The results indicate sustained growth in population, employment, and income can be expected to exert substantial upward pressure on regional electric power demand. Furthermore, demand is found to be price-inelastic in this metropolitan area, suggesting that rate increases can help raise the revenues necessary to fund expansion of the electrical grid.

    Spatial segmentation of the labour market of informal workers within the metropolitan is observed globally. InIndia it is not only compartmentalised on gender, caste, ethnic lines but also geographically segmented by thecreation of spatially disjoined markets. The differential impact of this limited mobility on female and malelabour remains largely unexplored. The present paper argues that the labour market for informal workers issegmented into smaller labour markets separated by commuting (h...

    2016-10-01

    Intensive urbanization is swallowing municipal green areas which causes intensification of erosion, decrease in biodiversity and permanent fragmentation of habitats. In the face of these changes, a risk of irreversible damages to urban ecosystems is growing. That is why planning of solutions within the framework of Green Urbanism in metropolitan areas inhabited by over 55% of the global population is of extraordinary importance. The task of the paper is to present patterns of the Green Urbanism using selected examples of metropolitan areas as case studies. The main goal of the research is to make comparison between GU practices in different countries, in various spatial settings. The principles of triple zero framework: zero fossil-fuel energy use, zero waste, zero emissions (from low-to-no-carbon emissions) introduce not only the contemporary trends in theoretical urban planning but are dictated by practical considerations to create a healthy environment for a healthy society with a minimized environmental footprint. The research results help to identify Green Urbanism techniques used for multiple functions, including ecological, recreational, cultural, aesthetic and other uses and present opportunities for implementation of Green Urbanism solutions in metropolitan areas. To achieve healthier society and environment, highly congested and polluted cities have to be recreated through working with the existing landscape, topography and natural resources particular to the site.

    2016-08-01

    Uber and similar rideshare services are rapidly dispersing in cities across the United States and beyond. Given the convenience and low cost, Uber has been characterized as a potential countermeasure for reducing the estimated 121 million episodes of drunk driving and the 10,000 resulting traffic fatalities that occur annually in the United States. We exploited differences in the timing of the deployment of Uber in US metropolitan counties from 2005 to 2014 to test the association between the availability of Uber's rideshare services and total, drunk driving-related, and weekend- and holiday-specific traffic fatalities in the 100 most populated metropolitan areas in the United States using negative binomial and Poisson regression models. We found that the deployment of Uber services in a given metropolitan county had no association with the number of subsequent traffic fatalities, whether measured in aggregate or specific to drunk-driving fatalities or fatalities during weekends and holidays. © The Author 2016.

    Sovacool, Benjamin K.; Brown, Marilyn A.

    2010-01-01

    A dearth of available data on carbon emissions and comparative analysis between metropolitan areas make it difficult to confirm or refute best practices and policies. To help provide benchmarks and expand our understanding of urban centers and climate change, this article offers a preliminary comparison of the carbon footprints of 12 metropolitan areas. It does this by examining emissions related to vehicles, energy used in buildings, industry, agriculture, and waste. The carbon emissions from these sources - discussed here as the metro area's partial carbon footprint - provide a foundation for identifying the pricing, land use, help metropolitan areas throughout the world respond to climate change. The article begins by exploring a sample of the existing literature on urban morphology and climate change and explaining the methodology used to calculate each area's carbon footprint. The article then depicts the specific carbon footprints for Beijing, Jakarta, London, Los Angeles, Manila, Mexico City, New Delhi, New York, Sao Paulo, Seoul, Singapore, and Tokyo and compares these to respective national averages. It concludes by offering suggestions for how city planners and policymakers can reduce the carbon footprint of these and possibly other large urban areas. (author)

  4. Is Urban Planning in Australia Hindered by Poor Metropolitan Governance?

    Directory of Open Access Journals (Sweden)

    Paul Burton

    2017-11-01

    Full Text Available There are many calls for urban planning in Australia to be reformed, although often in contradictory ways. For example, some argue it should be capable of delivering greater certainty to developers while others call for more flexibility in processes of urban development regulation; some would like to roll back its regulatory impact while others argue for a renewal of planning’s commitment to promoting social and spatial justice. The Australian planning system is also held to be hindered by a comparative lack of planning at and for the metropolitan scale. This is connected to the absence of well-developed structures of metropolitan governance in what is a three-tier federal system, with most power over planning concentrated at the State and Territory government scale. The paper explores this putative hindrance by considering three important issues in Australian urban policy debates about the efficacy of contemporary multi-level governance arrangements: spatial scale; identity and legitimacy; and efficiency and effectiveness. It includes some analysis of the case made for a more explicit and rigorous national urban policy and how this might relate to lower level planning regimes. The paper focuses on recent urban policy and planning initiatives in South East Queensland, one of Australia’s fastest growing metropolitan regions, and concludes that while incremental but nonetheless significant improvements in planning policy and practice are possible, these are unlikely to satisfy those calling for more radical changes to improve the Australian planning system.

    2010-12-01

    Munich Re once ranked that Tokyo metropolitan region, the capital of Japan, is the most vulnerable area for earthquake disasters, followed by San Francisco Bay Area, US and Osaka, Japan. Seismologists also predict that Tokyo metropolitan region may have at least one near-field earthquake with a probability of 70% for the next 30 years. Given this prediction, Japanese Government took it seriously to conduct damage estimations and revealed that, as the worst case scenario, if a7.3 magnitude earthquake under heavy winds as shown in the fig. 1, it would kill a total of 11,000 people and a total of direct and indirect losses would amount to 112,000,000,000,000 yen(1,300,000,000,000, 1=85yen) . In addition to mortality and financial losses, a total of 25 million people would be severely impacted by this earthquake in four prefectures. If this earthquake occurs, 300,000 elevators will be stopped suddenly, and 12,500 persons would be confined in them for a long time. Seven million people will come to use over 20,000 public shelters spread over the impacted area. Over one millions temporary housing units should be built to accommodate 4.6 million people who lost their dwellings. 2.5 million people will relocate to outside of the damaged area. In short, an unprecedented scale of earthquake disaster is expected and we must prepare for it. Even though disaster mitigation is undoubtedly the best solution, it is more realistic that the expected earthquake would hit before we complete this business. In other words, we must take into account another solution to make the people and the assets in this region more resilient for the Tokyo metropolitan earthquake. This is the question we have been tackling with for the last four years. To increase societal resilience for Tokyo metropolitan earthquake, we adopted a holistic approach to integrate both emergency response and long-term recovery. There are three goals for long-term recovery, which consists of Physical recovery, Economic

    Seismic disaster risk mitigation in urban areas constitutes a challenge through collaboration of scientific, engineering, and social-science fields. Examples of collaborative efforts include research on detailed plate structure with identification of all significant faults, developing dense seismic networks; strong ground motion prediction, which uses information on near-surface seismic site effects and fault models; earthquake resistant and proof structures; and cross-discipline infrastructure for effective risk mitigation just after catastrophic events. Risk mitigation strategy for the next greater earthquake caused by the Philippine Sea plate (PSP) subducting beneath the Tokyo metropolitan area is of major concern because it caused past mega-thrust earthquakes, such as the 1703 Genroku earthquake (magnitude M8.0) and the 1923 Kanto earthquake (M7.9) which had 105,000 fatalities. A M7 or greater (M7+) earthquake in this area at present has high potential to produce devastating loss of life and property with even greater global economic repercussions. The Central Disaster Management Council of Japan estimates that the M7+ earthquake will cause 11,000 fatalities and 112 trillion yen (about 1 trillion US$) economic loss. This earthquake is evaluated to occur with a probability of 70% in 30 years by the Earthquake Research Committee of Japan. In order to mitigate disaster for greater Tokyo, the Special Project for Earthquake Disaster Mitigation in the Tokyo Metropolitan Area (2007-2011) was launched in collaboration with scientists, engineers, and social-scientists in nationwide institutions. The results that are obtained in the respective fields will be integrated until project termination to improve information on the strategy assessment for seismic risk mitigation in the Tokyo metropolitan area. In this talk, we give an outline of our project as an example of collaborative research on earthquake risk mitigation. Discussion is extended to our effort in progress and

    1999-01-01

    Daytime and night-time population densities bordering Interstate highway routes in metropolitan areas are compared at the traffic analysis zone level. In three of the metropolitan areas studied, histograms of daytime to night-time population density ratios are peaked at 1.0. In a smaller metropolitan area, the peak of the histogram moves to values greater than 1.0 but less than 2.0. In view of the typical uncertainties in calculating radiological transport effects (∼2), this study indicates that a distinction between daytime and night-time transport is not warranted, especially since a typical route includes extensive transport outside metropolitan areas.

    Beneath the Tokyo metropolitan area, the Philippine Sea Plate (PSP) subducts and causes damaged mega-thrust earthquakes. Sato et al. (2005) revealed the geometry of upper surface of PSP, and Hagiwara et al. (2006) estimated the velocity structure beneath Boso peninsula. However, these results are not sufficient for the assessment of the entire picture of the seismic hazards beneath the Tokyo metropolitan area including those due to an intra-slab M7+ earthquake. So, we launched the Special Project for Earthquake Disaster Mitigation in the Tokyo Metropolitan area (Hirata et al., 2009). Proving the more detailed geometry and physical properties (e.g. velocities, densities, attenuation) and stress field within PSP is very important to attain this issue. The core item of this project is a dense seismic array called Metropolitan Seismic Observation network (MeSO-net) for making observations in the metropolitan area (Sakai and Hirata, 2009; Kasahara et al., 2009). We deployed the 249 seismic stations with a spacing of 5 km. Some parts of stations construct 5 linear arrays at interval of 2 km such as Tsukuba-Fujisawa (TF) array, etc. The TF array runs from northeast to southwest through the center of Tokyo. In this study, we applied the tomography method to image the heterogeneous structure under the Tokyo metropolitan area. We selected events from the Japan Meteorological Agency (JMA) unified earthquake list. All data of MeSO-net were edited into event data by the selected JMA unified earthquake list. We picked the P and S wave arrival times. The total number of stations and events are 421 and 1,256, respectively. Then, we applied the double-difference tomography method (Zhang and Thurber, 2003) to this dataset and estimated the fine-scale velocity structure. The grid nodes locate 10 km interval in parallel with the array, 20 km interval in perpendicular to the array; and on depth direction, 5 km interval to a depth of less than 50 km and 10 km interval at a depth of more

    2001-05-01

    The metropolitan area of Naples due to intense human activities is an emblematic area affected by various environmental pollution of soils and waters in addition to hydrogeological volcanic, seismic and bradyseismic hazards. The geology of the area is prevailing represented by volcanics erupted, from the Upper Pleistocene to Recent by Mt. Somma-Vesuvius on the east and the Campi Flegrei fields on the west. The morphology of the metropolitan area of Naples city can be subdivided in flat areas, constituted by reworked pyroclastic terrains, and by hills originated by the overlapping of different welded pyroclastic flows (i.e.: Campanian Ignimbrite and Neapoletan Yellow Tuff) intercalated with pyroclastic deposits of different origins (i.e.: Campi Flegrei, Mt. Somma-Vesuvius, Ischia) and ages. In order to compile a multi-element baseline geochemical and radioactivity mapping of the metropolitan area of the Napoli we have sampled for this study, in situ top soil and imported filling material (mainly soil, volcanic ash, pumice and scoriae). The sampling and radioactivity survey has been carried out on about 200 sampling sites covering an area of about 150 Km2, with a grid of 0.5 x 0.5 km in the urbanised downtown and 1 km x 1 km in the sub urban areas. In each site has been determined a radioactivity by a Scintrex GRS-500 at different emission spectra as total radioactivity (> 0.08 MeV and > 0.40 MeV), 238U (at 1.76 MeV mostly from 214Bi), 232Th (at 2.6 MeV mostly from 208Tl) and 40K (at 1.46 MeV mostly for 40K). The range of values of in situ soils are as follow for the in situ soils (Total radioactivity: 1327- 360 and 114- 47; 238U: 2.6- 1.3; 40K: 8.1- 3.1; 232U: 0.5- 0.1). Analyses of major, metallic elements and pH of each soil sample are in progress, while Pb isotopes compositions, for a selected number of samples, will be determined to discriminate the natural (geogenic) from the anthropogenic components in the soils by versus the anthropogenetic origin.

    Full Text Available Background Urban heat island (UHI effect, the ubiquitous consequence of urbanization, is considered to play a major role in population expansion of numerous insects. Cryptotympana atrata and Hyalessa fuscata are the most abundant cicada species in the Korean Peninsula, where their population densities are higher in urban than in rural areas. We predicted a positive relationship between the UHI intensities and population densities of these two cicada species in metropolitan Seoul. Methods To test this prediction, enumeration surveys of cicada exuviae densities were conducted in 36 localities located within and in the vicinity of metropolitan Seoul. Samples were collected in two consecutive periods from July to August 2015. The abundance of each species was estimated by two resource-weighted densities, one based on the total geographic area, and the other on the total number of trees. Multiple linear regression analyses were performed to identify factors critical for the prevalence of cicada species in the urban habitat. Results C. atrata and H. fuscata were major constituents of cicada species composition collected across all localities. Minimum temperature and sampling period were significant factors contributing to the variation in densities of both species, whereas other environmental factors related to urbanization were not significant. More cicada exuviae were collected in the second rather than in the first samplings, which matched the phenological pattern of cicadas in metropolitan Seoul. Cicada population densities increased measurably with the increase in temperature. Age of residential complex also exhibited a significantly positive correlation to H. fuscata densities, but not to C. atrata densities. Discussion Effects of temperature on cicada densities have been discerned from other environmental factors, as cicada densities increased measurably in tandem with elevated temperature. Several mechanisms may contribute to the abundance of

    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.

  2. Sedimentary Records of Hyperpycnal Flows and the Influence of River Damming on Sediment Dynamics of Estuaries: Examples from the Nelson, Churchill, Moisie and Sainte-Marguerite Rivers (Canada)

    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.

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.

  4. Spatial mismatch, wages and unemployment in metropolitan areas in Brazil

    Full Text Available The spatial mismatch hypothesis states that a lack of connection to job opportunities may affect an individual’s prospects in the labour market, especially for low-skilled workers. This phenomenon is especially observed in large urban areas, in which low-skilled minorities tend to live far away from jobs and face geographical barriers to finding and keeping jobs. This paper aims to investigate whether this negative relationship between spatial mismatch and labour market outcomes is valid in Brazil after controlling for individual characteristics. Our conclusions indicate that there is no clear relation between different measures of accessibility to jobs and the probability of being unemployed. However, for wages there is a clear correlation, which is stronger in larger metropolitan areas in the country. Given the exploratory nature of this work, our results still rely on strong identification hypotheses to avoid potential bias related to simultaneous location decisions of workers and firms within the city. Even if these conditions do not hold, the results are still meaningful as they provide a better understanding of the conditional distribution of wages and the unemployment rate in the biggest metropolitan areas of Brazil.

    Full Text Available Introduction Hearing loss can compromise the language, learning process, and socialization of students. Objective Study the audiometric findings among Curitiba and Metropolitan Area students. Methods Analysis of data collected at the hearing health service of Paraná State special education and inclusion department. Results The sample consisted of 646 students, children and teenagers of both genders (38.2% female and 61.8% male, with average age of 8.12 years (range 2 to 15; all were students of public or private schools of Curitiba and Metropolitan Area. The justifications to refer the students to audiometric evaluation were: otolaryngologists diagnosis (73.1%, school difficulties (39.6%, and midlevel hearing problems (32%. Audiometric results showed that 29.5% of the students had hearing loss. Conductive hearing losses showed the greatest occurrence among preschool students (right ear 38.6%, left ear 39.8%. The predominant hearing loss degree was mild (RE 20.5%, LE 19.3% to slight (RE 17%, LE 19.3%, as was the horizontal configuration (RE 81.5%, LE 78.4%. A significant relationship (p = 0.0000 between hearing loss and poor school performance was noted. Conclusion Considering the available data, especially the high number of findings of conductive losses, it is necessary to highlight prevention and diagnosis of early hearing alteration. Nevertheless, Brazil, as an emerging country, has been pursuing improvement in health and life quality of all citizens.

    Full Text Available With the rising and intensification of production’s activities, as industries, the deforestation taxes show to be on an alarming level. It is wide spread known the consequences that deforestation might cause in metropolitan areas. In order to evalue the consequences of this growing phenomenon, is possible to use a role of ambiental impacts evaluations techniques. One of them is the Preliminary Analysis of Danger (PAD, which is based on qualitative and statistics analysis and might be used in association with other ambiental impacts evaluations techniques. It’s goal is to analyze dangers in potential, it’s causes and consequences, in which is also done an associated risk analysis, which the last is the association between the classifications of frequency and severity, and, in the end, it gives suggestions of measures to avoid these dangers (undesired events. In this study, six dangers have been identified, in which none of them present despicable or low risk (0%, 16% present medium or high risk and 66% present critic risk. These datas point out that the deforestation situation might cause dangers with great consequences to Petropolis’ metropolitan area, just as floodings and earth slidings, which higthlights the urgency of management of the area. DOI: http://dx.doi.org/10.12957/sustinere.2015.20003

    Full Text Available OBJECTIVE To analyze the correlation between sociodemographic factors and working conditions of bus workers in a metropolitan area and violence against them. METHODS This cross-sectional study used a nonprobabilistic sample estimated according to the number of workers employed in bus companies located in three cities in the Belo Horizonte metropolitan region in 2012 (N = 17,470. Face-to-face interviews were conducted using a digital questionnaire. The factors associated with violence were analyzed in two stages using Poisson regression, according to each level. The magnitude of the association was evaluated using prevalence ratios with robust variance and a statistical significance of 5%, and 95% confidence intervals were obtained. RESULTS The study sample comprised 782 drivers and 691 fare collectors; 45.0% participants reported at least one act of violence in the workplace in the last 12 months, with passengers being predominantly responsible. The age of the bus workers was inversely associated with violence. Chronic diseases, sickness absenteeism, and working conditions were also associated with violence. CONCLUSIONS The findings on the correlation between violence and working conditions are essential for implementing prevention strategies by transportation service managers.

    Full Text Available Research purpose. In order to implement the optimal metropolitan governance model, it is important to understand the conditions under which this or that model is economically effective. There is a need to develop a quantitatively justified methodology for choosing the optimal metropolitan governance model for different types of metropolitan areas. It has been emphasized in some federal documents of Russia, for example, in the “Recommendations for the selection of pilot projects for approbation and improvement of mechanisms for managing the development of metropolitan areas in the Russian Federation”.Materials and methods. Domestic researchers (N. Zubarevich, K. Gonchar, etc. and foreign researchers (Glaeser Edward L., Nakamura, Ciccone A., Hall R., etc. carried out the study of quantitative relationships between the economic growth of cities and the characteristics of cities.However, for metropolitan areas, the analysis of the relationship has not yet been implemented between the outpacing economic growth of the metropolitan area relative to the average country values (labor productivity and GDP per capita, the institutional factor (the type of metropolitan governance model, andthe non-institutional factor (population size. To identify the dependencies we are interested in, we used the OECD statistical database and OECD researches to identify the metropolitan governance model in the sample of metropolitan areas in the world. The sample in this research was 87 metropolitan areas in Europe and was divided into groups, depending on the population and the introduced metropolitan governance model. For each group, a correlation-regression analysis was performed and a weighted average was calculated from the indexes of the economic growth. As the leading index of the economic growth, labor productivity was used, as the final - GDP per capita. Then a comparison was made between the real value of economic growth in each surveyed metropolitan area and

    To test the hypothesis that the relationship between deprivation and mortality is weaker among residents of non-metropolitan areas of England and Wales than among residents of metropolitan areas. This study compared mortality, expressed as standardised mortality ratios (SMRs), in residents of metropolitan and non-metropolitan districts at three levels of deprivation classified by an electoral ward deprivation score and by home and car ownership. SMRs were computed for all causes of death, for bronchitis and asthma (ICD9 codes 490-493), and for accident, violence, and poisoning (ICD9 codes 800-999). England and Wales. Members of the longitudinal study of the Office of Population Censuses and Surveys, a quasi-random 1% sample of the population of England and Wales. There was an association between deprivation and mortality which was clear for all cause mortality, more noticeable for respiratory disease, and less clear for deaths from accident, violence, and poison. In general, the results showed a remarkable similarity between metropolitan and non-metropolitan areas. This study does not support the hypothesis that the relationship between mortality and deprivation differs between residents of metropolitan and non-metropolitan areas of England and Wales.

    Metropolitan develops in line with resource utilization, investment, and transactions of regional activities. Metropolization of an area gives emerge urban economy that changes the situation, form, and pattern of urban space interactions. On the other hand, metropolism concerns the strategy of changing variation of urban space, so that metropolitan invasion not only form of urban space but also the process of interaction among stakeholders in developing metropolitan area. Based on participatory research, this article explores metropolitan invasion process for enhancing local and regional planning, both indigenous and intrusive cataclysmic. The study find that the primeval, rural, and urban as elemental environment must be considered in developing metropolitan, not merely form the structure and pattern of urban space. The metropolization process also requires the strategic of rural urban linkage, context setting and local assessment, strategic community investment, and interculturalist approach. The other findings of the study show that metropolization in Cirebon Metropolitan, West Java emphasizing on promotion of competitiveness strategy, value chain urban activities, and networking of urban areas. Cirebon Metropolitan must promote the realization of growth centers and connect the interregional activities of metropolitan area for providing sustainable economic growth.

    Full Text Available Abstract Background Disparities in injury rates between Aboriginal and non-Aboriginal populations in British Columbia (BC are well established. Information regarding the influence of residence on disparities is scarce. We sought to fill these gaps by examining hospitalization rates for all injuries, unintentional injuries and intentional injuries across 24 years among i Aboriginal and total populations; ii populations living in metropolitan and non-metropolitan areas; and iii Aboriginal populations living on- and off-reserve. Methods We used data spanning 1986 through 2010 from BC’s universal health care insurance plan, linked to vital statistics databases. Aboriginal people were identified by insurance premium group and birth and death record notations, and their residence was determined by postal code. “On-reserve” residence was established by postal code areas associated with an Indian reserve or settlement. Health Service Delivery Areas (HSDAs were classified as “metropolitan” if they contained a population of at least 100,000 with a density of 400 or more people per square kilometre. We calculated the crude hospitalization incidence rate and the Standardized Relative Risk (SRR of hospitalization due to injury standardizing by gender, 5-year age group, and HSDA. We assessed cumulative change in SRR over time as the relative change between the first and last years of the observation period. Results Aboriginal metropolitan populations living off-reserve had the lowest SRR of injury (2.0, but this was 2.3 times greater than the general British Columbia metropolitan population (0.86. For intentional injuries, Aboriginal populations living on-reserve in non-metropolitan areas were at 5.9 times greater risk than the total BC population. In general, the largest injury disparities were evident for Aboriginal non-metropolitan populations living on-reserve (SRR 3.0; 2.5 times greater than the general BC non-metropolitan population (1

    Full Text Available This article aims to explore the causes of informal settlements in Ekurhuleni Metropolitan Municipality (EMM. The article strongly challenges the view that the cause of informal settlements in EMM and other parts of South Africa is predominantly the apartheid government and agrees with literature which provides evidence that to a larger extent, the present government, not the apartheid government, is one of the dominant causes of informal settlements. The article further establishes a common and fertile ground for the convergence of the different views and perspectives into variables which, in addition to the present government, include population growth, government economic policies, economic variables, housing shortage, unavailability of land and unaffordability as the real causes of informal settlements in EMM.

    Massage offers cancer patients general quality of life benefits as well as alleviation of cancer-related symptoms/cancer-treatment–related symptoms including pain, anxiety, and fatigue. Little is known about whether massage is accessible to cancer patients who receive treatment in the outpatient setting and how massage is incorporated into the overall cancer treatment plan. Outpatient cancer centers (n = 78) in a single metropolitan area were included this mixed-methods project that included a systematic analysis of website information and a telephone survey. Massage was offered at only 40 centers (51.3% of total). A range of massage modalities were represented, with energy-based therapies (Reiki and Therapeutic Touch) most frequently provided. Although massage therapists are licensed health care providers in the states included in this analysis, massage was also provided by nurses, physical therapists, and other health care professionals.

    2003-01-01

    Between 1953 and 1965, Ogden Lindsley and his associates conducted free-operant research with psychiatric inpatients and normal volunteers at Metropolitan State Hospital in Waltham, Massachusetts. Their project, originally named "Studies in Behavior Therapy," was renamed "Harvard Medical School Behavior Research Laboratory" in 1955. This name change and its implications were significant. The role of the laboratory in the history of the relationship between the experimental analysis of behavior and applied behavior analysis is discussed. A case is made for viewing Lindsley's early work as foundational for the subfield of the experimental analysis of human behavior that formally coalesced in the early 1980s. The laboratory's work is also contextualized with reference to the psychopharmacological revolution of the 1950s. Finally, a four-stage framework for studying the historical and conceptual development of behavior analysis is proposed.

    2016-11-01

    Full Text Available Achieving the paradigm of sustainable urban mobility requires institutional capacities, appropriate policies and a regulatory framework that contains them. This work aims to contribute to the knowledge of the regulation of urban mobility in the metropolitan area of Mendoza. To this end, the current mobility regulations are assessed through indicators that are classified into three key areas: institutional and political organization, urban system and financial setup. The purpose is to account for the existence, or not, of regulatory capacities contained in the paradigm of sustainable mobility. Among the results, the absence of a policy of sustainable urban mobility is noteworthy, as well as the lack of sectorial coordination. Also of note is the absence of coordination between the urban planning system and the public transport provision. Lastly, in the financial sector, the results point to a promotion of sustainable transport modes but without such an explicit purpose.

    Previous studies suggested that aerosol optical depth (AOD) from the Earth Observing System satellite retrievals could be used for inference of ground-level air quality in various locations. This application may be appropriate if pollution in elevated atmospheric layers is insignificant. This study investigated the significance of elevated air pollution layers over the Bangkok Metropolitan Region (BMR) from all available aerosol layer scenes taken from Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) for years 2007 to 2011. The results show that biomass burning smoke layers alone were the most frequently observed. The smoke layers accounted for high AOD variations and increased AOD levels. In the dry seasons, the smoke layers alone with high AOD levels were likely brought to the BMR via northeasterly to easterly prevailing winds and found at altitudes above the typical BMR mixing heights of approximately 0.7 to 1.5 km. The smoke should be attributed to biomass burning emissions outside the BMR.

    Conventional solid waste management planning usually focuses on economic optimization, in which the related environmental impacts or risks are rarely considered. The purpose of this paper is to illustrate the methodology of how optimization concepts and techniques can be applied to structure and solve risk management problems such that the impacts of air pollution, leachate, traffic congestion, and noise increments can be regulated in the iong-term planning of metropolitan solid waste management systems. Management alternatives are sequentially evaluated by adding several environmental risk control constraints stepwise in an attempt to improve the management strategies and reduce the risk impacts in the long run. Statistics associated with those risk control mechanisms are presented as well. Siting, routing, and financial decision making in such solid waste management systems can also be achieved with respect to various resource limitations and disposal requirements.

    Quantum Key Distribution (QKD) is maturing quickly. However, the current approaches to its application in optical networks make it an expensive technology. QKD networks deployed to date are designed as a collection of point-to-point, dedicated QKD links where non-neighboring nodes communicate using the trusted repeater paradigm. We propose a novel optical network model in which QKD systems share the communication infrastructure by wavelength multiplexing their quantum and classical signals. The routing is done using optical components within a metropolitan area which allows for a dynamically any-to-any communication scheme. Moreover, it resembles a commercial telecom network, takes advantage of existing infrastructure and utilizes commercial components, allowing for an easy, cost-effective and reliable deployment.

    Massage offers cancer patients general quality of life benefits as well as alleviation of cancer-related symptoms/cancer-treatment-related symptoms including pain, anxiety, and fatigue. Little is known about whether massage is accessible to cancer patients who receive treatment in the outpatient setting and how massage is incorporated into the overall cancer treatment plan. Outpatient cancer centers (n = 78) in a single metropolitan area were included this mixed-methods project that included a systematic analysis of website information and a telephone survey. Massage was offered at only 40 centers (51.3% of total). A range of massage modalities were represented, with energy-based therapies (Reiki and Therapeutic Touch) most frequently provided. Although massage therapists are licensed health care providers in the states included in this analysis, massage was also provided by nurses, physical therapists, and other health care professionals.

    Site selection for waste disposal is a complex task that should meet the requirements of communities and stakeholders. In this article, three decision support methods (Boolean logic, index overlay and fuzzy gamma) are used to perform land suitability analysis for landfill siting. The study was carried out in one of the biggest metropolitan regions of Italy, with the objective of locating suitable areas for waste disposal. Physical and socio-economic information criteria for site selection were decided by a multidisciplinary group of experts, according to state-of-the-art guidelines, national legislation and local normative on waste management. The geographic information systems (GIS) based models used in this study are easy to apply but require adequate selection of criteria and weights and a careful evaluation of the results. The methodology is arranged in three steps, reflecting the criteria defined by national legislation on waste management: definition of factors that exclude location of landfills or waste treatment plants; classification of the remaining areas in terms of suitability for landfilling; and evaluation of suitable sites in relation to preferential siting factors (such as the presence of quarries or dismissed plants). The results showed that more than 80% of the provincial territory falls within constraint areas and the remaining territory is suitable for waste disposal for 0.72% or 1.93%, according to the model. The larger and most suitable sites are located in peripheral areas of the metropolitan system. The proposed approach represents a low-cost and expeditious alternative to support the spatial decision-making process. © The Author(s) 2014.

    Microzonation deals with classifying seismic hazards in terms of ground motions resulting from amplification of seismic waves by nature of soil profiles underlying a site, town or city. This paper presents the results of microzonation study for Islamabad metropolitan, the capital of Pakistan. Cumulative SPT- N values from geophysical borehole and microtremor (Tromino Engy Plus) data were used to classify the soils into classes C (very dense soil profile and soft rock) and D (stiff soil profile) as devised by the National Earthquake Hazard Reduction Program (NEHRP). Soil response analyses were carried out based on scaled time histories of Kashmir earthquake (2005, 0.02 g), Mangla earthquake (2006, 0.031 g) and Haripur earthquake (2010, 0.13 g) corresponding to return periods of 150, 475, 975 and 2475 years. Spectral accelerations on the ground surface are calculated by two different approaches (1) soil response analysis performed using one dimensional shear wave propagation method (equivalent linear approach); and (2) NEHRP and Borcherdt amplification factors. Microzonation maps are produced with respect to ground shaking intensity for the return periods of 150, 475, 975 and 2475 years taking into account the variation of the spectral accelerations calculated based on these two procedures. The results show that the accelerations at the ground surface in the Islamabad-Rawalpindi metropolitan are in the range of 0.40-0.48 g (for 150 years), 0.59-0.65 g (for 475 years), 0.71-0.77 g (for 975 years), and 0.92-0.94 g (for 2475 years). The amplification factors for these four hazard levels range from 0.96 to 1.38 (150 years), 0.90-1.14 (475 years), 0.85-1.04 (975 years) and 0.84-1.00 (2475 years).

    Full Text Available Rapid changes in information and communication technologies cause serious developments in marketing field similar to every sector. In parallel with these developments, the social media channels which appear as Web 2.0 applications have a number of advantages in comparison with traditional media channels. Social media gained a place in marketing activities because of its advantages. Social media is added on instruments in line with these developments that countries benefit in marketing activities for attracting more tourists, investment and becoming prominent against the other cities. Cities intensively benefit from social media because of social media’s properties like reaching the large masses, low marketing cost, interaction, receiving feedbacks rapidly, etc. Within this context, the purpose of this research is to determine the use statuses of social media by metropolitan municipalities as part of city marketing. In accordance with this purpose, official social media accounts of 30 metropolitan municipalities are investigated between the dates of 01/09/2016 and 30/09/2016, then their shares in social media channels are investigated in the context of city marketing.It is observed that two metropolitan municipalities do not have official Facebook accounts, four metropolitan municipalities do not have an official Twitter account as well. Again, it is found that 19 metropolitan municipalities do not have an official Instagram account and 17 metropolitan municipalities do not have official YouTube account. In consequence, it is observed that, our metropolitan municipalities do not benefit from social media effectively for city marketing activities.

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.

    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.

    Japan frequently suffers from all types of disasters such as earthquakes, typhoons, floods, volcanic eruptions, and landslides. In the first half of this year, we already had three big earthquakes and heavy rainfall, which killed more than 30 people. This is not just for Japan but Asia is the most disaster-afflicted region in the world, accounting for about 90% of all those affected by disasters, and more than 50% of the total fatalities and economic losses. One of the most essential ways to reduce the damage of natural disasters is to educate the general public to let them understand what is going on during those desasters. This leads individual to make the sound decision on what to do to prevent or reduce the damage. The Ministry of Education, Culture, Sports, Science and Technology (MEXT), therefore, offered for public subscription to choose several model areas to adopt scientific education to the local elementary schools, and ERI, the Earthquake Research Institute, is qualified to develop education for earthquake disaster prevention in the Tokyo metropolitan area. The tectonic setting of this area is very complicated; there are the Pacific and Philippine Sea plates subducting beneath the North America and the Eurasia plates. The subduction of the Philippine Sea plate causes mega-thrust earthquakes such as the 1703 Genroku earthquake (M 8.0) and the 1923 Kanto earthquake (M 7.9) which had 105,000 fatalities. A magnitude 7 or greater earthquake beneath this area is recently evaluated to occur with a probability of 70 % in 30 years. This is of immediate concern for the devastating loss of life and property because the Tokyo urban region now has a population of 42 million and is the center of approximately 40 % of the nation's activities, which may cause great global economic repercussion. To better understand earthquakes in this region, "Special Project for Earthquake Disaster Mitigation in Tokyo Metropolitan Area" has been conducted mainly by ERI. It is a 4-year

    Radon is a radioactive gas released from the normal decay of 238 U in rocks and soil. It is an invisible, odorless, tasteless gas that seeps up through the ground and diffuses into the air. In a few areas, depending on local geology, radon dissolves into ground water and can be released into the air when the water is used. Radon gas usually exists at very low levels outdoors. However, in areas without adequate ventilation, such as underground mines, radon can accumulate to levels that substantially increase the risk of lung cancer. Radon decays quickly, giving off tiny radioactive particles. When inhaled, these radioactive particles can damage the cells that line the lung. Long-term exposure to radon can lead to lung cancer, the only cancer proven to be associated with inhaling radon. Public interest in radon has been occasionally piqued by articles in the general press. Considerable attention has been given to the high radon levels that were uncovered in the Reading Prong region of Pennsylvania, following the discovery in late 1984 of extremely high levels in one home. Several epidemiological study programmes in different countries are in progress to estimate the population exposures due to natural radiation with a view to obtain the radiation risk coefficients at low dose rate levels. In this regard, radiation surveys in high background areas (HBRAs) can provide excellent settings for epidemiological studies relating to the effects of low doses of radiation. In view of these, a comprehensive estimate of the natural inhalation dose requires both 222 Rn and 220 Rn levels in the indoor atmosphere. In this outlook an attempt is made to investigate the 222 Rn and 220 Rn levels in dwellings of Bangalore Metropolitan, India. Three year results shows that the activity concentrations of 226 Ra, 232 Th, radon in ground water, the concentrations 222 Rn and 220 Rn and the dose rate (mSvy -1 ) are at alarming levels for the environment of Bangalore Metropolitan, India.

    Full Text Available Agricultural land covers more than half the area of metropolitan areas in Poland, and is therefore particularly prone to the influences of the processes associated with their development. The aim of the study was to analyse changes in agricultural land cover within the metropolitan areas of Poland for the years 1990–2012; and to capture their dynamics, types and directions. The percentage share of the total study area, for each of the forms of agricultural land cover and their changes were traced, with the spatial distribution of the changes also being determined. The results of the study show that in metropolitan areas, agricultural land cover is undergoing transformations that do not result in the loss of agricultural lands, or that involve a decrease in surface area due to their change into anthropogenic forms of land cover. The greatest transitions occurred between 2000 and 2006 and were observed in the outer zones of metropolitan areas.

    Full Text Available The central locations of metropolitan areas have some specific attributes, leading to an accumulation of large knowledge exchanges and extensive knowledge externalities, which encourage the concentration of various economic activities, especially knowledge-based industries (KBI. Other agglomeration economies found in metropolitan areas – such as telecommunications and transport infrastructures connected to global productive circuits and complementary labour markets – are key factors for KBI employment growth. This paper explores the Helsinki Metropolitan Area’s (HMA spatial clustering of KBI at the sub-district level, and the role played by agglomeration economies (both specialization and diversity economies in fostering this process. The results reveal that KBI employment shows patterns of concentration in the core and adjacent areas. The specialization and diversity economies found in the metropolitan core and the specialization economies found in others areas lead to KBI spatial clustering in the HMA. Public policies regarding the promotion of science parks have also played a decisive role.

    Full Text Available This paper tries to explore the process of urbanization and spatial changes in demographic features in the Monterrey Metropolitan Region (MMR, Mexico. This city is the third largest urban sector in Mexico which has around 4 million population. It is also the industrial and economic capital of the country. The present study found that rapid urbanization in the metropolitan region has a close association with process of industrialization. In population distribution and composition, study found that the metropolitan region had its “demographic transition” during the years seventies and currently the region is taking advantages of demographic bonus cohort, i.e. a higher concentration of population in economic active groups compare to children and old age population. However, this paper indentified a higher imbalance in metropolitan demographic scenario. On the one hand, there is di-populization in the city center region and in other there is a steady increment of population in peri-urban region.

    2014-07-01

    Full Text Available This paper is a morphological study on Beijing’s metropolitanisation process based on the development of its transportation networks. By extracting the ‘scale structure’ embedded in them, we construct a movement network model for Beijing and use it to analyse changing metropolitan centralities as shopping areas and market places in 1924, 1987 and 2006. Following Taylor’s proposal of Central Flow as a complementary model to Central Place, our study focuses on how the spatial distribution of metropolitan centralities has been affected by the rapid modernisation of transportation networks.

    Chlorinated-solvent compounds are among the most common groundwater contaminants in the U.S.A. The majority of the many sites contaminated by chlorinated-solvent compounds are located in metropolitan areas, and most such areas have one or more chlorinated-solvent contaminated sites. Thus, contamination of groundwater by chlorinated-solvent compounds may pose a potential risk to the sustainability of potable water supplies for many metropolitan areas. The impact of chlorinated-solvent sites on...

  6. The Hydro-Economic Interdependency of Cities: Virtual Water Connections of the Phoenix, Arizona Metropolitan Area

    Full Text Available Water footprinting has revealed hydro-economic interdependencies between distant global geographies via trade, especially of agricultural and manufactured goods. However, for metropolitan areas, trade not only entails commodity flows at many scales from intra-municipal to global, but also substantial intra-metropolitan flows of the skilled labor that is essential to a city’s high-value economy. Virtual water flows between municipalities are directly relevant for municipal water supply policy and infrastructure investment because they quantify the hydro-economic dependency between neighboring municipalities. These municipalities share a physical water supply and also place demands on their neighbors’ water supplies by outsourcing labor and commodity production outside the municipal and water supply system boundary to the metropolitan area. Metropolitan area communities span dense urban cores to fringe agricultural towns, spanning a wide range of the US hydro-economy. This study quantifies water footprints and virtual water flows of the complete economy of the Phoenix Metropolitan Area’s municipalities. A novel approach utilized journey to work data to estimate virtual water flows embedded in labor. Commodities dominate virtual water flows at all scales of analysis, however labor is shown to be important for intra-metropolitan virtual water flows. This is the first detailed water footprint analysis of Phoenix, an important city in a water-scarce region. This study establishes a hydro-economic typology for communities to define several niche roles and decision making points of view. This study’s findings can be used to classify communities with respect to their relative roles, and to benchmark future improvements in water sustainability for all types of communities. More importantly, these findings motivate cooperative approaches to intra-metropolitan water supply policy that recognize the hydro-economic interdependence of these

    2014-01-23

    This study applied remote sensing technology to analyze how rivers in the urban environment affect the surface temperature of their ambient areas. While surface meteorological stations can supply accurate data points in the city, remote sensing can provide such data in a two-dimensional (2-D) manner. The goal of this paper is to apply the remote sensing technique to further our understanding of the relationship between the surface temperature and rivers in urban areas. The 2-D surface temperature data was retrieved from Landsat-7 thermal infrared images, while data collected by Formosat-2 was used to categorize the land uses in the urban area. The land surface temperature distribution is simulated by a sigmoid function with nonlinear regression analysis. Combining the aforementioned data, the range of effect on the surface temperature from rivers can be derived. With the remote sensing data collected for the Taipei Metropolitan area, factors affecting the surface temperature were explored. It indicated that the effect on the developed area was less significant than on the ambient nature zone; moreover, the size of the buffer zone between the river and city, such as the wetlands or flood plain, was found to correlate with the affected distance of the river surface temperature.

    2003-03-01

    The paper presents an overview of the present situation of the Mexico City Metropolitan Area (MCMA). The analysis indicates an urgent need to radically improve the current water supply and wastewater management practices, to become sustainable. The MCMA is one of the most rapidly growing urban centers of the world, with a population of about 21 million people, a very high rate of immigration and numerous illegal settlements. In order to meet the increasing water demand, successive governments have focused almost exclusively on supply management and engineering solutions, which have resulted in investments of hundreds of millions of USD and the construction of major infrastructure projects for interbasin water transfer. Environmental, economic and social policies associated with water management are mostly inadequate and insufficient, which is resulting in increasing deterioration in the environment, health and socioeconomic conditions of a population living in one of the largest urban agglomerations of the world. Surprisingly, however, no long-term strategies on demand-management, reuse, conservation, and improved water-management practices have been developed so far.

  9. Secular variations of radon in metropolitan Vancouver, British Columbia, Canada

    International Nuclear Information System (INIS)

    Ghomshei, M.M.; Slawson, W.F.

    1990-01-01

    In this paper sampling of radon within the soil from three sites in metropolitan Vancouver is reported. Alpha trace bi-weekly measurements during a period of 4 years show secular variations with a period of 8-15 months. There are low-radon and high-radon episodes enduring several months to a year. Average radon level during the high-radon episodes reaches 5-10 times that of the low-radon periods. During high-radon episodes the high-frequency variations show very high amplitudes. After filtering of the high-frequency fluctuations, the data from different sites demonstrate remarkably similar trends. It is suggested that along with hydrogeological events, stress relaxation in rocks, earthquake, and magma emplacement may contribute to the sources of secular variations of radon. Because of long-term variations, radon level in urban areas should be monitored on a continuous basis. Single measurements, even those integrating radiation over a period of few months, may sample a low-radon episode, and provide a false assurance, or occur during a high-radon episode and give a false alarm

  10. EVALUATION OF PRIVATE SCHOOL LOCATION IN THE ISTANBUL METROPOLITAN AREA

    Full Text Available Investment in education is considered important for economic growth and poverty alleviation. In many developed and developing countries families contribute privately to the education of their children as a result of continuously shrinking public budgets. Also, in Istanbul private primary schools were supported by the government in order to answer to increasing demand due to continuous rural migration and to create a competitive educational market to improve the quality of primary education. This paper, first, analyzes the spatial distribution of private primary schools according to the concentric rings and illustrates the gap between the center and the periphery and among the districts. Then, the relationships between the number of private primary schools and demand and the characteristics of the districts are investigated by a regression analysis. According to the results, the number of public primary schools is the most important factor and GDP per capita is the second factor to affect the number of private primary schools in the districts. Currently, the cluster of private primary schools mainly in high-income districts does not allow developing a competitive educational market at the metropolitan level. It is expected that a more balanced market will be develop as the urban structure of Istanbul adjusted to the neo-liberal economies in the future. The results are useful for urban planners, investors and policy makers. Further research is suggested to investigate the impact of private primary schools on the quality of public primary school education in Istanbul.

    Full Text Available Land take is a phenomenon of great concern nowadays because of the large number of its negative impacts regarding biological, economic and social balance. In Italy, the development of urban and other artificial land has been irreversibly transforming a non-renewable resource such as soil, regardless the almost constant population rate, with different speed depending of the region considered. The aim of this paper is to analyze the phenomenon in the metropolitan area of Naples, which is an area highly affected by territorial aggression of human matrix. The data used are both by the Institute for Environmental Protection and Research (ISPRA Report 2015 on the usage of the land and by ISTAT relating to the resident population up to the 1st of January 2015 and the extension of land for agricultural use (Census 2010. The mathematical combination of this data creates a new indicator that can be referred to as “residual land”; this residual area is of great extension with many different characteristics and it could represent the area where the phenomenon of land take most occurs. The identification, measurement and analysis of “residual land” provide new insights on the evolution of land take and this new indicator can represent a critical element to work on to prevent future land transformation and protect natural and agricultural areas within the Italian context.

    Please cite this paper as: Van Buynder et al. (2010) Marketing paediatric influenza vaccination: results of a major metropolitan trial. Influenza and Other Respiratory Viruses 5(1), 33–38. Objectives  After a cluster of rapidly fulminant influenza related toddler deaths in a Western Australian metropolis, children aged six to 59 months were offered influenza vaccination in subsequent winters. Some parental resistance was expected and previous poor uptake of paediatric influenza vaccination overseas was noted. A marketing campaign addressing barriers to immunization was developed to maximise uptake. Design  Advertising occurred in major statewide newspapers, via public poster displays and static ‘eye‐lite’ displays, via press releases, via a series of rolling radio advertisements, via direct marketing to child care centres, and via a linked series of web‐sites. Parents were subsequently surveyed to assess reasons for vaccination. Main Outcome Results  The campaign produced influenza vaccination coverage above that previously described elsewhere and led to a proportionate reduction in influenza notifications in this age group compared to previous seasons. Conclusions  Influenza in children comes with significant morbidity and some mortality. Paediatric influenza vaccination is safe, well tolerated and effective if two doses are given. A targeted media campaign can increase vaccine uptake if it reinforces the seriousness of influenza and addresses community ‘myths’ about influenza and influenza vaccine. The lessons learned enabling enhancements of similar programs elsewhere. PMID:21138538

    The objective of the present study, was to elaborate a profile of the contamination by private matter and to characterize the aerosols collected in the Metropolitan Area of San Jose (Costa Rica). For that, a campaign of sampling was carried out in three points of the city of San Jose, differentiated by there degree of activity: Center of San Jose (Central Station of Firemen), San Isidro of Coronado -Canton of Vasquez of Coronado- (Municipality) and Escazu (Municipality). Such campaign was carried out from April 4 to July 4, 1996 (transition summer-winter), and in two periods of time of 8 hours: 8 a.m. to 4 p.m. and of 8 p.m. to 4 a.m. The aerosols were collected utilizing Gent Pm-10 samplers, in filters of polycarbonate of 0,4 μm and 8 μm in cascade, with a flow average of 15 L/min., and it determined the composition average of the present aerosols. The concentration of the majority of the anions were obtained by means of ionic chromatography of high resolution, and the main cations by spectrophotometry of atomic absorption with electro thermic atomization. The space-temporary variations of the concentrations were evaluated and their correlation with the meteorologic variable. (S. Grainger) [es

    The emissions inventory bears a broad relationship to the energy balance, reflecting the dependence of the emissions with reference to the use of energy. Actually the consumption of gasoline and diesel fuel in the transport sector represents collectively, the greatest comparative expense of energy and the major contributor of the ozone precursor pollutants HC, NO{sub x} and CO, relative to the total volume of emissions in the Mexico City Metropolitan Area (MCMA). Also, the industrial sector introduces significant emissions of SO{sub 2} and NO{sub x} due to its energy consumption of fuel oils and natural gas. In contrast, the great majority of suspended particulate in the MCMA emanate from degradation processes of surface soil along the periphery of the urban zone. To the federal and local authorities charged with the design of strategies for prevention and control of atmospheric pollution, the emissions inventory is a strategic tool that reflects the relative intensity of the various emitters to the load capacity of the atmosphere. A comprehensive inventory was compiled for 1995, categorizing the emissions generated by four sectors: industry, services, transport and surface soils and vegetation, considering the following pollutants: TSP, SO{sub 2}, NO{sub x}, HC and CO. The combined pollutant emissions are 4,009,628 tons/year of which 3% are generated by the industry, 10% by the services sector, 75% by the transport sector, and 12% by surface soils and vegetation.

    The main concern of this paper was to predict the sludge quantities generated from 18 wastewater treatment plants, which were stated to be established in the "Istanbul Water Supply, Sewerage and Drainage, Sewage Treatment and Disposal Master Plan", 10 of which are in operation at present. Besides this, obtaining the required data to compare various treatment schemes was another goal of the study. Especially, the estimation of the sludge quantity in the case of enhanced primary sedimentation was of importance. Wastewater sludge management strategies were discussed in order to develop suggestions for Istanbul Metropolitan city. Within this context, the wastewater treatment facilities, mentioned in the Master Plan that had been completed by 2000, were evaluated in terms of sludge production rates, locations and technical and management aspects. Disposal alternatives of the wastewater treatment sludge were also evaluated in this study. Using of the dewatered sludge as a landfill cover material seems the best alternative usage. Up to the year of 2040, the requirement of cover material for landfills in Istanbul will be met by the dewatered sludge originated from wastewater treatment plants in the region.

    Quantum key distribution (QKD) systems have already reached a reasonable level of maturity. However, a smooth integration and a wide adoption of commercial QKD systems in metropolitan area networks has still remained challenging because of technical and economical obstacles. Mainly the need for dedicated fibers and the strong dependence of the secret key rate on both loss budget and background noise in the quantum channel hinder a practical, flexible and robust implementation of QKD in current and next-generation optical metro networks. In this paper, we discuss these obstacles and present approaches to share existing fiber infrastructures among quantum and classical channels. Particularly, a proposal for a smooth integration of QKD in optical metro networks, which implies removing spurious background photons caused by optical transmitters, amplifiers and nonlinear effects in fibers, is presented and discussed. We determine and characterize impairments on quantum channels caused by many classical telecom channels at practically used power levels coexisting within the same fiber. Extensive experimental results are presented and indicate that a practical integration of QKD in conventional optical metro networks is possible.

    Deployment of Broadband ISDN is being influenced by both a market pull and a technology push. New broadband service opportunities exist in the business and residential sectors of the market place. It is envisioned that some customers will need connections directly to broadband switches because of the high bandwidth needed for their applications. At the same time Metropolitan Area Network (MAN) systems will serve those customers with bandwidth requirements less than or equal to 150 Mbps. A given MAN will have a geographical domain to serve where it will carry out the switching tasks within this domain. While MANs couldbe designed using differentarchitecturalconcepts the setofservices expected tobeprovidedby MANs could be equivalent to thelist ofservices thatwillbe supported by the targetbroadband network. This paperpositions MANs as a major building block for Broadband networks. It also examines the evolution process ofMANs as a needed step to assure the successful deployment of these new broadband services. 2. BISDN - OVERVIEW Broadband ISDN (BISDN) is being driven into existence by both a market pull as well as a technology push. Opportunities for new valueadded services are the prime market pull for future broadband networks. These services opportunities extend beyond simple voice and low speed data applications and cover both the residential and the business sectors of the market. It is noted for instance that business customers have growing needs for sophisticated telecommunication vehicles to support their

    Lucknow metropolitan city is one of the most populated cities of India, which have been facing many problems such as chaotic urbanization, overpopulation, water scarcity, waterlogging, etc., among these water scarcity is one of the important problem. Rain water harvesting is a futuristic tool for mitigation of water scarcity problem through conservation and storage of rain water. This rain water can be used for all purposes by human beings, thus it is necessary to check the chemistry of rain water. The rain water samples were collected from the five zones of Lucknow city. For the comparative study, water samples have been collected from two different dates first from first rainfall and second after 3 days of interval in the second rainfall. The heavy metal concentrations were found in both first and second rainfall water samples in all zones of Lucknow city. The concentration of chromium, cadmium and lead were found to be sufficiently high in several samples. These heavy metals show the concentration above the permissible limit as set by WHO, which can cause various adverse health impacts.

  20. Water crisis: the metropolitan Atlanta, Georgia, regional water supply conflict

    2014-07-01

    Many large population centres are currently facing considerable difficulties with planning issues to secure future water supplies, as a result of water allocation and environmental issues, litigation, and political dogma. A classic case occurs in the metropolitan Atlanta area, which is a rapidly growing, large population centre that relies solely on surface water for supply. Lake Lanier currently supplies about 70% of the water demand and has been involved in a protracted legal dispute for more than two decades. Drought and environmental management of the reservoir combined to create a water shortage which nearly caused a disaster to the region in 2007 (only about 35 days of water supply was in reserve). While the region has made progress in controlling water demand by implementing a conservation plan, per capita use projections are still very high (at 511 L/day in 2035). Both non-potable reuse and indirect reuse of treated wastewater are contained in the most current water supply plan with up to 380,000 m3/day of wastewater treated using advanced wastewater treatment (nutrient removal) to be discharged into Lake Lanier. The water supply plan, however, includes no additional or new supply sources and has deleted any reference to the use of seawater desalination or other potential water sources which would provide diversification, thereby relying solely on the Coosa and Chattahoochee river reservoirs for the future. © 2014 IWA Publishing.

  1. Truck transport of RAM: Risk effects of avoiding metropolitan areas

    International Nuclear Information System (INIS)

    Mills, G.S.; Neuhauser, K.S.

    1997-11-01

    In the transport of radioactive material (RAM), e.g., spent nuclear fuel (SNF), stakeholders are generally most concerned about risks in high population density areas along transportation routes because of the perceived high consequences of potential accidents. The most significant portions of a transcontinental route and an alternative examined previously were evaluated again using population density data derived from US Census Block data. This method of characterizing population that adjoins route segments offers improved resolution of population density variations, especially in high population density areas along typical transport routes. Calculated incident free doses and accident dose risks for these routes, and the rural, suburban and urban segments are presented for comparison of their relative magnitudes. The results indicate that modification of this route to avoid major metropolitan areas through use of non-Interstate highways increases total risk yet does not eliminate a relatively small urban component of the accident dose risk. This conclusion is not altered by improved resolution of route segments adjoining high density populations

    Face recognition is used to prove identity across a wide variety of settings. Despite this, research consistently shows that people are typically rather poor at matching faces to photos. Some professional groups, such as police and passport officers, have been shown to perform just as poorly as the general public on standard tests of face recognition. However, face recognition skills are subject to wide individual variation, with some people showing exceptional ability-a group that has come to be known as 'super-recognisers'. The Metropolitan Police Force (London) recruits 'super-recognisers' from within its ranks, for deployment on various identification tasks. Here we test four working super-recognisers from within this police force, and ask whether they are really able to perform at levels above control groups. We consistently find that the police 'super-recognisers' perform at well above normal levels on tests of unfamiliar and familiar face matching, with degraded as well as high quality images. Recruiting employees with high levels of skill in these areas, and allocating them to relevant tasks, is an efficient way to overcome some of the known difficulties associated with unfamiliar face recognition.

    Mammography screening behavior has not been well studied among Middle Eastern immigrant women. We conducted a telephone survey of 365 Arab American women residing in metropolitan Detroit, home to one of the largest populations of Middle Eastern immigrants in the US, to determine prevalence of factors associated with mammography, and attitudes and beliefs regarding mammography screening. Of 365 participants, only five were born in the US. Mean age was 53.2 years (SD 10.8). Two hundred twelve (58.1%) reported having mammogram every 1-2 years; 70% ever had mammogram. Age 50-64 years, having health insurance, married status, being in the US over 10 years, and being Lebanese were associated with mammography every 1-2 years. After adjusting for demographic factors, perceived seriousness of disease, general health motivation, and having fewer barriers were associated with more frequent screening. Appropriate mammography screening is decreased in this group. Targeted outreach regarding screening is appropriate for this population; however, lack of insurance may prevent adequate follow-up.

  4. A slotted access control protocol for metropolitan WDM ring networks

    Baziana, P. A.; Pountourakis, I. E.

    2009-03-01

    In this study we focus on the serious scalability problems that many access protocols for WDM ring networks introduce due to the use of a dedicated wavelength per access node for either transmission or reception. We propose an efficient slotted MAC protocol suitable for WDM ring metropolitan area networks. The proposed network architecture employs a separate wavelength for control information exchange prior to the data packet transmission. Each access node is equipped with a pair of tunable transceivers for data communication and a pair of fixed tuned transceivers for control information exchange. Also, each access node includes a set of fixed delay lines for synchronization reasons; to keep the data packets, while the control information is processed. An efficient access algorithm is applied to avoid both the data wavelengths and the receiver collisions. In our protocol, each access node is capable of transmitting and receiving over any of the data wavelengths, facing the scalability issues. Two different slot reuse schemes are assumed: the source and the destination stripping schemes. For both schemes, performance measures evaluation is provided via an analytic model. The analytical results are validated by a discrete event simulation model that uses Poisson traffic sources. Simulation results show that the proposed protocol manages efficient bandwidth utilization, especially under high load. Also, comparative simulation results prove that our protocol achieves significant performance improvement as compared with other WDMA protocols which restrict transmission over a dedicated data wavelength. Finally, performance measures evaluation is explored for diverse numbers of buffer size, access nodes and data wavelengths.

    Radon progenies are identified as major causes of the lung cancer if the activity is above its normal. It has not been clear whether radon poses a similar risk of causing lung cancer in humans exposed at generally lower levels found in homes, but a number of indoor radon survey have been carried out in recent years around the world. In view of this an attempt has been made for the measurement of diurnal variation of indoor radon levels for the environment of Bangalore metropolitan, India. The Radon progeny concentrations in terms of working level were measured using Kusnetz's method. The patterns of daily and annual changes in indoor Radon concentration have been observed in a general way for many years. However, understanding of the physical basis for these changes had to await the development of continuous monitors and a more complete knowledge of transport processes in the atmosphere. Over a continent, heating of the ground surface by the Sun during the day and cooling by radiation during the night causes a marked diurnal change in temperature near the surface. As a result cool air near the ground will accumulate radon isotopes from surface flux during the night; while during the day the warm air will be transported upward carrying radon with it. Many buildings show diurnal radon variations. Concentrations are relatively higher during night than daytime. This is influenced by the outdoor-indoor temperature contrast. This effect can be enhanced in buildings with strong diurnal use patterns. Buildings that have high average radon concentrations, but are only occupied for part of the day, may need to be measured during occupied periods to determine if there is significant diurnal radon variation. The results are discussed in detail. (author)

  6. Designing Freshwater Resilience for the Mexico City Metropolitan Area

    Freeman, S.; Wi, S.; Brown, C.

    2017-12-01

    There are few places in the world where the water management challenges associated with global urbanization are as fully visible as in the Greater Mexico City Metropolitan Area (MCMA). MCMA has a population of 22 million of which only 82% have daily water provision and this figure is projected by local agencies to decrease drastically in the next decade due to population growth, infrastructure degradation and climate change. The city is served by a massive water delivery system, consisting of complex network of infrastructure in the surrounding basins that provides about 40% of the supply for MCMA and is characterized by increasing land use change and competition for water. The remaining 60% of MCMA's water is sourced internally from already depleted groundwater resources whose exploitation also results in significant subsidence throughout the city, further damaging already degraded infrastructure. Consequently, there is interest and need for investments that improve the performance of the freshwater delivery system, including local resources and connected basins, in the face of change and shocks that can be only partially anticipated. The quest for such resilience is a common theme in urban infrastructure design yet practical approaches for achieving it remain nascent. In this study, we use MCMA and the Cutzamala Water supply system to demonstrate a quantitative framework to evaluate investment strategies which seek resilience for the water supply system of MCMA. Multiobjective optimization and decisions under deep uncertainty approaches are used to evaluate the best performing investment portfolios across different resilience performance metrics which encompass social equity, environmental and economic objectives. This analysis shows dynamic system responses that result from different investment portfolios, elucidating difficult planning and management decisions around tradeoffs between allocations as well as performance metrics (e.g short period of total failure

    A study about household dust is being conducted to determine the level of metal contamination in the Sao Paulo Metropolitan Area (SPMA). The SPMA, with 18 million inhabitants, is one of the largest urban areas of the world, with serious environmental problems, due to the great amount of industries, heavy traffic and the disordered growth of population. The pollutants originate from a multiplicity of indoor and outdoor sources. Indoor sources are originated from residual (hair, skin scales), pets, human activities, construction materials, and furnishings as well as biological material (pollen, insect parts).and outdoor pollution, usually from the urban traffic. The pollutant mixture involved in numerous physical and chemical processes and changes its characteristics with time. Its composition and concentration depend on the strengths of indoor sources, the concentration of pollutants outside and the properties of ventilation and air-conditioning systems. It is well recognized that many metals have chronic effects on humans, in particular toddlers, who are at an higher risk compared to adults because they engage in greater hand to-mouth activity and their neurological systems are still developing. The household dust samples were collected from different localities, using vacuum cleaner, and sieved up to particle size -1 ; Mn, 119-369 μg g -1 ; Fe, 372-1464 μg g -1 ; Ni, 33-85 μg g -1 ; Cu, 42-303 μg g -1 ; Zn, 156-1369 μg g -1 and Pb, 26-160 μg g -1 .

    Human beings are exposed to ionizing radiation from many natural sources. Radon and its progeny have been recognized as the most important contributors to the natural radioactivity dose, accounting for about half of all human exposure to ionizing radiation. Radon ( 222 Rn) is a α-radioactive noble gas derived from the natural series of uranium (2 38 U), which occurs in a wide concentration range in all geological materials, especially, in rocks, soils and waters. By diffusion and convection, radon migrates from the rocks and soils to atmosphere and through fissures, pipes and holes it may enter the dwellings and other buildings. Another important radon source in dwellings is its emanation from the construction material. The radon progeny concentration in dwellings has been receiving considerable global attention due to its potential effect in causing lung cancer if it deposited in upper respiratory tract when inhaled. This paper presents radon concentration distribution in dwellings in Metropolitan Region of Belo Horizonte - RMBH. The effective dose estimate is also presented for the RMBH inhabitants. The geological settings of the area are Archean rocks of Granitic Gnaissic Complex and of metasediments sequences of the great Precambrian unit of the Iron Quadrangle of Minas Gerais, Brazil. Radon concentration measurements were carried out with continuous detector AlphaGUARD PQ200PRO (Genitron), in passive mode and with passive detectors E-PERM R Eletret Ion Chamber-EIC. The radon progeny concentration was carried out with a solid state alpha spectroscope, the DOSEman PRO (Sarad). It was found an indoor radon concentration varying in a large range from 18.5 to 2671.4 Bq/m -3 , with an average value of 148.0 Bqm -3 and geometric mean equal to 128.2 Bqm -3 . The variable results are due mainly to region geological factors and building material composition of dwellings. The equilibrium factor between radon and its progeny were determined in dwellings, as 0.3 in

    Scholars have largely overlooked the formative role of industry in both California's economic development and the San Francisco Bay Area's metropolitan expansion during the late nineteenth century. Beginning in the early 1880s, leading firms in San Francisco's specialized industries, such as the iron and chemicals sectors, dispersed to the metropolitan periphery. This process of industrial suburbanization created an integrative metropolitan economy, as well as individual suburbs. In this di...

    In Malaysia small towns are an important source of population gowth in metropolitan areas. To provide empirical evidence of the magnitude and roles of small urban centers as complementary sources of population growth in metropolitan areas, a small survey was conducted in 10 small towns in the State of Selangor. Criteria for the selection of these towns include a fair geographical spread over the State, and each area must characteristically possess a dominant urban center. The questionnaires were directed to the heads of 300 households with the intention of investigating the socioeconomic background of the households and the magnitude and characteristics of those members of the households who have migrated elsewhere. The total number of outmigrants from each area varied from 27-57, giving an overall average figure of 1.53 outmigrants/household. About 77% of the outmigrants had moved to the metropolitan centers. As the majority of the metropolitan migrants were more attracted to Kuala Lumpur, Klang, and Petaling Jaya, it may be assumed that the total outmigrants from small towns as derived would have consitituted about 39% of the population in the Klang Valley region. Based on this estimate, the role of small towns in metropolitan population growth is important. In the survey conducted, 2 broad categories of movements were involved: "economic movers," i.e., those who migrated to work or to establish businesses in the metropolitan areas; and "noneconomic movers," i.e., those who moved to continue their studies or to follow their spouses, and so forth. The economic mover stream made up 71% of the total metropolitan migrants. 2 variables--marital status and sex--were significantly related to the economic or noneconomic nature of the metropolitan migrants. The movement of males tended to be associated with economic motives whereas noneconomic reasons for movement tended to be the case among females migrants. The most important occupational group of the economically

    Previously published research for a single metropolitan market (Austin, Texas) found that periodontists fare poorly on the Yelp website for nearly all measured metrics, including average star ratings, number of reviews, review removal rate, and evaluations by "elite" Yelp users. The purpose of the current study is to confirm or refute these findings by expanding datasets to additional metropolitan markets of various sizes and geographic locations. A total of 6,559 Yelp reviews were examined for general dentists, endodontists, pediatric dentists, oral surgeons, orthodontists, and periodontists in small (Austin, Texas), medium (Seattle, Washington), and large (New York City, New York) metropolitan markets. Numerous review characteristics were evaluated, including: 1) total number of reviews; 2) average star rating; 3) review filtering rate; and 4) number of reviews by Yelp members with elite status. Results were compared in multiple ways to determine whether statistically significant differences existed. In all metropolitan markets, periodontists were outperformed by all other dental specialties for all measured Yelp metrics in this study. Intermetropolitan comparisons of periodontal practices showed no statistically significant differences. Periodontists were outperformed consistently by all other dental specialties in every measured metric on the Yelp website. These results were consistent and repeated in all three metropolitan markets evaluated in this study. Poor performance of periodontists on Yelp may be related to the age profile of patients in the typical periodontal practice. This may result in inadvertently biased filtering of periodontal reviews and subsequently poor performance in multiple other categories.

    The March 11, 2011 Tohoku-oki earthquake brought a great impact to the Tokyo metropolitan area in both seismological aspect and seismic risk management although Tokyo is located 340 km from the epicenter. The event generated very strong ground motion even in the metropolitan area and resulted severe requifaction in many places of Kanto district. National and local governments have started to discuss counter measurement for possible seismic risks in the area taking account for what they learned from the Tohoku-oki event which is much larger than ever experienced in Japan Risk mitigation strategy for the next greater earthquake caused by the Philippine Sea plate (PSP) subducting beneath the Tokyo metropolitan area is of major concern because it caused past mega-thrust earthquakes, such as the 1703 Genroku earthquake (M8.0) and the 1923 Kanto earthquake (M7.9). An M7 or greater (M7+) earthquake in this area at present has high potential to produce devastating loss of life and property with even greater global economic repercussions. The Central Disaster Management Council of Japan estimates that an M7+ earthquake will cause 11,000 fatalities and 112 trillion yen (about 1 trillion US$) economic loss. In order to mitigate disaster for greater Tokyo, the Special Project for Earthquake Disaster Mitigation in the Tokyo Metropolitan Area was launched in collaboration with scientists, engineers, and social-scientists in nationwide institutions. We will discuss the main results that are obtained in the respective fields which have been integrated to improve information on the strategy assessment for seismic risk mitigation in the Tokyo metropolitan area; the project has been much improved after the Tohoku event. In order to image seismic structure beneath the Metropolitan Tokyo area we have developed Metropolitan Seismic Observation network (MeSO-net; Hirata et al., 2009). We have installed 296 seismic stations every few km (Kasahara et al., 2011). We conducted seismic

    The intensities of seismic waves observed at the dense seismic array of the Tokyo Metropolitan Seismic Observation network (MeSO-net) inside the Kanto basin, display unusual distribution patterns. In several occasions, the highest intensities are not observed in the area above an earthquakes hypocenter but appear sifted more than 20 km away. In order to understand the source of this unusual intensity distribution pattern, it is crucial to understand how the waves attenuate before they reach the surface. The attenuation of seismic waves along their path is represented by the t∗ attenuation operator that can be obtained by fitting the observed seismic wave spectrum to a theoretical spectrum using an ω2 model. In order to create a high quality dataset, only 1449 earthquakes that are recorded with intensity greater than 0 in the Japan Meteorological Agency (JMA) intensity scale are selected from the JMA unified earthquake list from April 1st 2008 to October 2nd 2013. A grid search method is applied to determine the t∗ values by matching the observed and theoretical spectra. The t∗ data where then inverted to estimate a 3D Q structure with grid points set at a 10 km spacing. We implemented the 3D velocity model estimated by Nakagawa et al., 2012 and in addition we set the initial Q values at 100 for the 0 km grids and to 400 for the grids below them. The obtained model suggests average Q values of 50˜100 inside the Kanto basin. Furthermore, a low Q zone is observed in the area where the Philippine Sea plate meets the upper part of the Pacific sea plate. This area is located at approximately 40 km depth, beneath the north-east Tokyo and west Chiba prefectures and is represented by Q values Earthquakes occurring on the Pacific plate pass through this low Q area inside the Philippine sea plate and are attenuated significantly. The estimated attenuation distribution at the MeSO-net station for these earthquakes implementing our 3D Q model greatly coincides with the

    Full Text Available Abstract Background New pharmacological therapies are challenging the healthcare systems, and there is an increasing need to assess their therapeutic value in relation to existing alternatives as well as their potential budget impact. Consequently, new models to introduce drugs in healthcare are urgently needed. In the metropolitan health region of Stockholm, Sweden, a model has been developed including early warning (horizon scanning, forecasting of drug utilization and expenditure, critical drug evaluation as well as structured programs for the introduction and follow-up of new drugs. The aim of this paper is to present the forecasting model and the predicted growth in all therapeutic areas in 2010 and 2011. Methods Linear regression analysis was applied to aggregate sales data on hospital sales and dispensed drugs in ambulatory care, including both reimbursed expenditure and patient co-payment. The linear regression was applied on each pharmacological group based on four observations 2006-2009, and the crude predictions estimated for the coming two years 2010-2011. The crude predictions were then adjusted for factors likely to increase or decrease future utilization and expenditure, such as patent expiries, new drugs to be launched or new guidelines from national bodies or the regional Drug and Therapeutics Committee. The assessment included a close collaboration with clinical, clinical pharmacological and pharmaceutical experts from the regional Drug and Therapeutics Committee. Results The annual increase in total expenditure for prescription and hospital drugs was predicted to be 2.0% in 2010 and 4.0% in 2011. Expenditures will increase in most therapeutic areas, but most predominantly for antineoplastic and immune modulating agents as well as drugs for the nervous system, infectious diseases, and blood and blood-forming organs. Conclusions The utilisation and expenditure of drugs is difficult to forecast due to uncertainties about the rate

    1998-01-01

    A revised estimation has been made of the local air quality improvement that can be achieved in Tokyo as a byproduct of a word-wide hydrogen energy economy based on global reduction of CO2 emission from fossil fuels. The study for the WE-NET Project in Japan examined the potential for reduction in nitrogen oxide emission with hydrogen fuel in the Tokyo metropolitan area where sufficient data exist on trends in population, vehicle registrations, traffic activity, and exhaust emissions. A dynamic model was developed to extrapolate the trends in these data to estimate future NOx emission rates in comparison to regulatory scenarios based on policy and technical decisions of the Tokyo Metropolitan Government for improvement of air quality in the metropolitan area. The results of the model show significant potential for reduction of NOx emission by the year 2020 with a concomitant reduction in mean roadside NOx concentration. (author)

    Full Text Available The purpose of this study is to elucidate gender differences and regional differences of co-mmuting activities by inhabitants in Japanese metropolitan suburbs. I found the different parts by districts in the metropolitan suburb. Regional factors cause gender differences in commuting activities and result in regional differences: In residential areas, inhabitants who work in metropolitan centers occupy much of the population. In older built-up areas, there are many “local” persons. In rural areas, motorization is progressing because access to rail-roads has been inconvenient. These regional factors influence the behavioral characteristics of commuting by married men, married women, never married men and never married women.

    Los mayores costos de producción del clavel estándar se asocian con la mano de obra que se utiliza en las labores del cultivo; el desbotone es una de las actividades que demanda mayor uso de mano de obra y tiempo. El objetivo del estudio fue determinar el efecto del desbotone en diferentes estadios de desarrollo del botón principal, sobre la producción y calidad en poscosecha del clavel estándar variedad Nelson en el primer pico de cosecha. Se evaluaron los estadios conocidos popularmente como botón ‘arveja’, ‘garbanzo’, ‘barril’, ‘estrella’, ‘bala’ y ‘punto de corte’. Las variables medidas incluyeron producción total a primera cosecha, grados de calidad y algunos criterios de clasificación en poscosecha. Se concluyó que el desbotone en los estadios evaluados no influye significativamente en la producción total del clavel en la primera cosecha. Sin embargo, en la clasificación por grados de calidad, se encontraron diferencias significativas: el desbotone en botón arveja’, ‘garbanzo’ y ‘barril’ mostró mayores promedios en el número de tallos grado ‘select’, mientras que el desbotone en botón ‘estrella’, ‘bala’ y ‘punto de corte’ reflejó mayores promedios para los grados ‘fancy’ estándar y nacional. El desbotone en diferentes estadios de desarrollo del botón principal afectó el número de tallos torcidos, sin aumentar significativamente el número de tallos débiles. El ensayo permitió definir que la etapa crítica para el desbotone son los estadios de desarrollo del botón principal previos al estadio ‘barril’, pues pasado este punto disminuye la calidad del producto.

    This study investigates the impact of food price on obesity, by exploring the co-occurrence of obesity growth with relative food price reduction between 1976 and 2001. Analyses control for female labor participation and metropolitan outlet densities that might affect body weight. Both the first-difference and fixed effects approaches provide consistent evidence suggesting that relative food prices have substantial impacts on obesity and such impacts were more pronounced among the low-educated. These findings imply that relative food price reductions during the time period could plausibly explain about 18% of the increase in obesity among the U.S. adults in metropolitan areas.

    Full Text Available Commuting data at a district level and an algorithm designed to delineate self–contained areas show that Mexico City Metropolitan Area (MCMA was organized in 2007 in twelve local labour market areas. Although six exployment subcenters were identified, the MCMA is still clearly dominated by its Central Business District (CBD, being located the remaining five subcenters close to the CBD. Assessment of this spatial structure is not a positive one: diminishing co–location, decrease in speed and increase in commuting time and distance. Nevertheless, the rising percentage of intra–district commuting is a positive sign, even if this trend is not uniform throughout the metropolitan area.

    Full Text Available The article covers the last period of church-administrative activity of the Sofia’s metropolitan Stephаn (Shokov. The author describes the testimonies of contemporaries about the character and personal qualities of this ambiguous hierarch. In 1945–1948 metropolitan Stephan was the exarch of the Bulgarian Orthodox Church and participated in the Meeting of heads and representatives of Autocephalous Orthodox Churches in 1948. The author considers the circumstances of the dismissal of metropolitan Stephаn and his exile as especially important and interesting ones. The meeting of 1948 became the critical event in the exarch’s destiny. Being the supporter of ecumenism, metropolitan Stephen tried unsuccessfully to convince Patriarch Alexis of his rightness in order not to allow the condemnation of ecumenical contacts by the Moscow meeting. However Moscow looked on ecumenism differently in those days. In Moscow the Soviet management aspired to establishment of the centre of World Orthodoxy and tried to cite the Moscow Patriarchy against Constantinople that was under the influence of the USA and the Great Britain. As the Constantinople Patriarchy approved the ecumenical movement, the Moscow Patriarchy has been forced to take of an opposite position. Therefore, the participation of the Russian Church and Churches of the socialist countries in the ecumenical movement was impossible. Metropolitan Stephan, supporting the superiority of the Moscow Patriarchy in the World Orthodoxy, supported the active participation of all Local Churches in the ecumenical movement. The communistic management applied the maximum force to the exarch in order he has not made undesirable statements at the meeting. The fate of metropolitan Stephan has been decided after this meeting. In 1948 he was fired and exiled. The Moscow Patriarchy did not exclude the possibility of moving of metropolitan Stephаn to Russia and his location in any monastery. However metropolitan

    The Sao Paulo Metropolitan Area (SPMA), in the southeast region of Brazil, is considered a megalopolis comprised of Sao Paulo city and more 38 municipalities. The air pollutant emissions in the SPMA are related to the burning of the fuels: etanol, gasohol (gasoline with 25% ethanol) and diesel. According to CETESB (2013), the road vehicles contributed up to about 97, 87, and 80% of CO, VOCs and NOx emissions in 2012, respectively, being most of NOx associated to diesel combustion and most of CO and VOCs from gasohol and ethanol combustion. Studies conducted on ambient air pollution in the SPMA have shown that black carbon (BC) explains 21% of mass concentration of PM2.5 compared with 40% of organic carbon (OC), 20% of sulfates, and 12% of soil dust (Andrade et al., 2012). Most of the observed ambient PM2.5 mass concentration usually originates from precursors gases such as sulphur dioxide (SO2), ammonia (NH3), nitrogen oxides (NOx) and VOCs as well as through the physico-chemical processes such as the oxidation of low volatile hydrocarbons transferring to the condensed phase (McMurry et al., 2004). The Weather Research and Forecasting with Chemistry model (WRF-Chem; Grell et al. 2005), configured with three nested grid cells: 75, 15, and 3 km, is used as photochemical modeling to describe the physico-chemical processes leading to evolution of particles number and mass size distribution from a vehicular emission model developed by the IAG-USP laboratory of Atmospheric Processes and based on statistical information of vehicular activity. The spatial and temporal distributions of emissions in the finest grid cell are based on road density products compiled by the OpenStreetMap project and measurements performed inside tunnels in the SPMA, respectively. WRF-Chem simulation with coupled primary aerosol (dust and sea-salt) and biogenic emission modules and aerosol radiative effects turned on is conducted as the baseline simulation (Case_0) to evaluate the model

    The aim of the research is to evaluate the external costs of energy production at Helsinki metropolitan area (Helsinki, Espoo, Vantaa). The previously developed valorization method for effects on population centres is adjusted. All the main health, material and environmental effects will be taken into account in the research. The effects of emissions of the energy production of the Helsinki metropolitan area on concentrations of the impurities in the air and through them on human and environment will be evaluated. The estimates will be based on the relativistic fuels consumption and the emission data of Helsinki metropolitan area. Life-cycle reasoning will be applied so that the emissions of the main components of the fuels used in the metropolitan area will be included in the estimation. The cost-effectiveness of the investments will be estimated by comparing the environmental investments of energy boards with the external costs. The methods of this work can be applied to estimation of the profitability of energy production plants from the point of view of national economy also elsewhere in the country
