The current global crisis may change globalization itself, as both developed and developing countries adjust to global imbalances that contributed to the crisis. Will these changes help or hinder economic recovery and growth in South Asia? This is the focus of this paper. The three models of globalization--trade, capital, and economic management--may not be the same in the future. Changes ...

The Steel and Shipbuilding Industries of South Korea: Rising East Asia and Globalization

Directory of Open Access Journals (Sweden)

Kyoung-ho Shin

2015-08-01

Full Text Available In this paper, we focus on the roles of the steel and shipbuilding industries as generative sectors in Korea’s rapid economic ascent. We argue that a world-systems analysis focusing on these generative sectors provides a more complete understanding of Korea’s rapid economic ascent than do other theoretical models. We outline the similarities between this case and those analyzed by Bunker and Ciccantell (2005, 2007 both in terms of the central role of generative sectors in raw materials and transport industries and how the creation and growth of these two industrial sectors shaped institutional patterns and the broader economic ascent of South Korea and East Asia. Even though South Korea has not and may never become a challenger for global hegemony, its rapid ascent has helped reshape East Asia and the capitalist world-economy. We use the model of generative sectors to analyze the critical industries that underlay and shaped South Korea’s ascent from a low wage, light industry base to a world leader in electronics, automobiles, and other advanced industries.

Transnational entrepreneurship in the Global South: evidence from Southern Africa

Directory of Open Access Journals (Sweden)

Rogerson Jayne M.

2015-12-01

Full Text Available Transnational entrepreneurship is an evolving field of research which occupies an interface between social and regional sciences. The phenomenon of transnational entrepreneurship is driven by entrepreneurs that migrate from one country to another whilst maintaining business-related linkages with their former country of origin and the adopted country. The most critical distinguishing feature of transnational entrepreneurs is bifocality or the ability to function across two different business environments. Most writings on transnational entrepreneurship concentrate on business individuals from the global South operating enterprises in the global North. Absent are empirical studies of the nature and behaviour of transnational migrant entrepreneurs who operate across or between emerging or developing economies. This South-South gap in international research concerning transnational entrepreneurship is addressed in the paper which provides an exploratory analysis of the nature of transnational entrepreneurship occurring in Southern Africa using evidence of Zimbabwean transnational entrepreneurs based in Johannesburg, South Africa.

The Relevance of Criminal Courts in the Global South

Directory of Open Access Journals (Sweden)

Pablo Leandro Ciocchini

2017-12-01

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

Views from the Global South: exploring how student volunteers from the Global North can achieve sustainable impact in global health.

Ouma, Brian D O; Dimaras, Helen

2013-07-26

The body of research and practice regarding student volunteer abroad experiences largely focuses on ensuring the optimal learning experience for the student from the Global North, without equivalent attention to the benefits, if any, to the host institution in the Global South. In this debate article, we examine an often overlooked component of global student volunteer programs: the views of the local partner on what makes for a mutually beneficial partnership between volunteers from the Global North and institutions in the Global South. To guide our discussion, we drew upon the experiences of a Kenyan NGO with a Canadian student volunteer in the summer of 2012, organized via a formalized partnership with a Canadian university. We found that the approach of the NGO to hosting the student mirrored the organizational behaviour theories of Margaret J. Wheatley, who emphasized a disorderly or 'chaotic' approach to acquiring impactful change, coupled with a focus on building solid human relationships. Rather than following a set of rigid goals or tasks, the student was encouraged to critically engage and participate in all aspects of the culture of the organization and country, to naturally discover an area where his priorities aligned with the needs of the NGO. Solid networks and interpersonal connections resulted in a process useful for the organization long after the student's short-term placement ended. Our discussion reveals key features of successful academic volunteer abroad placements: equal partnership in the design phase between organizations in the Global North and Global South; the absence of rigid structures or preplanned tasks during the student's placement; participatory observation and critical engagement of the student volunteer; and a willingness of the partners to measure impact by the resultant process instead of tangible outcomes.

Meteorology of the Southern Global Plume: African and South American Fires Pollute the South Pacific

Science.gov (United States)

Guo, Z.; Chatfield, R. B.

1999-01-01

An immense global plume of CO meanders widely around the world in the Southern Hemisphere. It arises over Southern America and Africa and flows eastward. The first emissions are in tropical Brazil, and the plume circulates around the world to South America again. The plume was largely unexpected until there were aircraft studies made in NASA's Pacific Exploratory Mission - Tropics (Part A). This paper describes the meteorology of the Global Plume, as our simulation, with a synoptic model adapted to global transport, reveals it with a tracer-CO simulation. The observations and their simulation require a particular set of conditions of pollutant accumulation, cumulonimbus venting with required strengths at a narrow range of altitude. Additionally, a particular subtropical conduction region, over the Indian Ocean, Australia, and the westeRNmost South Pacific, relatively free of storms, appears to be a key part of the mechanism. These conclusions are the results of a synoptic reconstruction of the PEMT-A period, September- October, 1996.

Topside ionospheric vertical electron density profile reconstruction using GPS and ionosonde data: possibilities for South Africa

Directory of Open Access Journals (Sweden)

P. Sibanda

2011-02-01

Full Text Available Successful empirical modeling of the topside ionosphere relies on the availability of good quality measured data. The Alouette, ISIS and Intercosmos-19 satellite missions provided large amounts of topside sounder data, but with limited coverage of relevant geophysical conditions (e.g., geographic location, diurnal, seasonal and solar activity by each individual mission. Recently, methods for inferring the electron density distribution in the topside ionosphere from Global Positioning System (GPS-based total electron content (TEC measurements have been developed. This study is focused on the modeling efforts in South Africa and presents the implementation of a technique for reconstructing the topside ionospheric electron density (Ne using a combination of GPS-TEC and ionosonde measurements and empirically obtained Upper Transition Height (UTH. The technique produces reasonable profiles as determined by the global models already in operation. With the added advantage that the constructed profiles are tied to reliable measured GPS-TEC and the empirically determined upper transition height, the technique offers a higher level of confidence in the resulting Ne profiles.

Publishing South African scholarship in the global academic community

Science.gov (United States)

le Roux, Elizabeth

2015-01-01

South Africa's academic publishing history has been profoundly influenced by its colonial heritage. This is reflected in the publication of Transactions of the South African Philosophical Society (later, the Royal Society of South Africa) from 1878. Although the Society and journal sought to promote original research about South Africa, it was modelled after the Royal Society in London and formed part of an imperial scientific community. As the local higher education institutions grew more independent and research-focused, local scholarly publishing developed as well, with university presses playing an increasingly important role. The University of South Africa (Unisa) Press started publishing departmental journals in the 1950s, with a focus on journals that ‘speak to the student’, and it is today the only South African university press with an active journals publishing programme. As external funding declined and the country became intellectually isolated in the high apartheid period, the Press managed to attract journals that could no longer be subsidized by learned societies and other universities. More recently, new co-publishing arrangements have brought South African journals back into an international intellectual community. Although some argue that this constitutes a re-colonization of South African knowledge production, it is also an innovative strategy for positioning local research in a global context. PMID:26495579

Susceptibility of South Korea to Extremes Affecting the Global Food System

Chon, So Young; Puma, Michael J.

2015-01-01

Food security in South Korea is tightly linked to the global food system. The country's production of major grains declined from 5.8 million metric tons (mmt) in 1998 to 4.8 mmt in 2014, which caused the country's grain self suciency to decline from 31.4% to 24%. This decline is a consequence of several factors including reductions in domestic agricultural land, governmental policies supporting industry over agriculture, and a push towards trade liberalization. South Korea's self suciency is now one of the lowest among Organisation for Economic Co-operation and Development (OECD) countries, leaving it vulnerable to disruptions in the global food system.

A SOUTH AFRICAN PERSPECTIVE ON MUTUAL LEGAL ASSISTANCE AND EXTRADITION IN A GLOBALIZED WORLD

Directory of Open Access Journals (Sweden)

Murdoch Watney

2012-08-01

Full Text Available This contribution focuses on the modalities of mutual legal assistance and extradition from a South African perspective. The question is posed whether South Africa has succeeded to establish the required framework as a fully fledged member of the international community to make a positive contribution in the fields of mutual legal assistance and extradition subsequent to its international political isolation during the apartheid era. Although the international community derives substantial benefit from a borderless global world, it has as a result also to deal with the negative impact of globalization on international crime. Physical and/or electronic crimes are increasingly committed across borders and may be described as borderless, but law enforcement (combating, investigation and prosecution of crime is still very much confined to the borders of a state. Criminal networks have taken advantage of the opportunities resulting from the dramatic changes in world politics, business, technology, communications and the explosion in international travel and effectively utilize these opportunities to avoid and hamper law enforcement investigations. As a sovereign state has control over its own territory it also implies that states should not interfere with each other’s domestic affairs. The correct and acceptable procedure would be for a state (requesting state to apply to another state (requested state for co-operation in the form of mutual legal assistance regarding the gathering of evidence and/or extradition of the perpetrator. Co-operation between states are governed by public international law between the requesting and requested state and the domestic law of the requested state. The South African legislature has increasingly provided for extraterritorial jurisdiction of South African courts in respect of organized crime and terrorism. It does however appear that existing criminal justice responses are experiencing challenges to meet the

GLOBAL COMPETITION BETWEEN NORTH AND SOUTH

Full Text Available The human-geographic regionalization is a landmark in the demarcation of territories that include populations of the same demographic, cultural or economic background. A defining boundary for human characteristics across the planet can be made simple, between the North and the South. The north, though advanced economically, militarily, technologically, united, well-urbanized and landscaped, dominates the world for just 500 years before the South was in power. After a long period of stagnation, the South escapes the colonialist chains until the 1950s, after which begins a vast process of revival in which emerging new powers are emerging as well as a series of economic unions that can rival with the old powers in the North. Analyzing the number of inhabitants in the two regions, it is noted that demographic size is a priority in the slope of the power balance, so when one of the regions exceeded 50% of the total population of the Globe, it attracted wealth by exporting populations and culture that colonized the other half. After 1950, the South holds for the first time 400 years, over 50% of the total population, and in 2017 it reaches 62%, reaching 71% in 2050 and 81% of the world's population by 2100. understands that the economic difficulties in the North, financial crises, the limitation of global influence or the issue of immigrants is only at the beginning, and the transformation of the North into the southern vassal is just a matter of time.

Sub-Saharan Africa at the global education market: role of South Africa

Directory of Open Access Journals (Sweden)

Ramil Ravilevich Asmyatullin

2016-12-01

Full Text Available This article is dedicated to the development of the higher education in Sub-Saharan countries, particularly to the topic of internationalization of education. Most African countries have underdeveloped education systems. The quality and availability of higher education is a formidable obstacle for economic and social development. There is a growing demand for higher education in the SSA, but national education systems can’t cope fully with it. Hence many students go abroad, mostly in other African countries. The article focuses on the position of South Africa in the global and regional education market. As it’s a regional leader in this field South Africa attracts more than a half of international students within the Sub-Saharan Africa. The main reasons why African students choose South Africa are geographic proximity, familiar culture, lack of wanted higher education programs in their countries. However, there are as well disadvantages like xenophobia and race discrimination. South Africa has become a leader in Africa in the field of higher education, but it plays still small part at a global scale.

Pursuing Qualitative Research From the Global South: "Investigative Research" During China's "Great Leap Forward" (1958-62

Directory of Open Access Journals (Sweden)

Ping-Chun Hsiung

2015-07-01

Full Text Available Over the last decade, qualitative researchers have begun to challenge the domination and universalistic claims of the Global North. Nevertheless, it is still unclear what pursuing qualitative research (QR from the Global South might entail. I advance this effort by situating it in the larger context of the decentering endeavor in social science and decolonizing methodologies in aboriginal scholarship. Informed by their locally-grounded approach in the quest for constructing alternative social science accounts and articulating decolonized knowledge, I argue that writing locally-grounded histories is an essential first step to explore methodologies and epistemologies of QR from the Global South. Noting that no national history of QR has been derived from the Global South, I present an example of writing the history of QR by examining MAO Zedong's legacy of "investigative research" (IR. Specifically, I analyze the practices of IR during China's "Great Leap Forward" (1958-62. In conclusion, I discuss the implications of IR to the development of social science research in contemporary China. I lay out key issues in pursuing QR from the Global South and present how such a pursuit is relevant to social science inquiry in the Global North.

Linking the South Atlantic Meridional Overturning Circulation and the Global Monsoons

Science.gov (United States)

Lopez, H.; Dong, S.; Goni, G. J.; Lee, S. K.

2016-02-01

This study tested the hypothesis whether low frequency decadal variability of the South Atlantic meridional heat transport (SAMHT) influences decadal variability of the global monsoons. A multi-century run from a state-of-the-art coupled general circulation model is used as basis for the analysis. Our findings indicate that multi-decadal variability of the South Atlantic Ocean plays a key role in modulating atmospheric circulation via interhemispheric changes in Atlantic Ocean heat content. Weaker SAMHT produces anomalous ocean heat divergence over the South Atlantic resulting in negative ocean heat content anomaly about 15 years later. This, in turn, forces a thermally direct anomalous interhemispheric Hadley circulation in the atmosphere, transporting heat from the northern hemisphere (NH) to the southern hemisphere (SH) and moisture from the SH to the NH, thereby intensify (weaken) summer (winter) monsoon in the NH and winter (summer) monsoon in the SH. Results also show that anomalous atmospheric eddies, both transient and stationary, transport heat northward in both hemispheres producing eddy heat flux convergence (divergence) in the NH (SH) around 15-30°, reinforcing the anomalous Hadley circulation. Overall, SAMHT decadal variability leads its atmospheric response by about 15 years, suggesting that the South Atlantic is a potential predictor of global climate variability.

A Meta-Analysis of Human–Wildlife Conflict: South African and Global Perspectives

2016-12-01

Full Text Available Human–wildlife conflict (HWC, due to competition for shared natural resources between people and wildlife, influences food security of people and the well-being of people and animals. HWC is a major concern in developing countries, affecting people of different socio-economic classes. We conducted a meta-analysis of the occurrence of published scientific reports on HWC globally and South Africa particularly, to identify vulnerable human communities and their farming practices in developing and developed countries, and vulnerable wildlife guilds. We accessed Institute for Scientific Information publications from 1994 to 2015. Local communities (people living contiguous with protected natural areas and commercial farmers jointly experienced the highest HWC incidences compared to subsistence farmers, possibly due to reporting bias for commercial farmers. Rural people in Africa and Asia experienced conflict with a diversity of mammals, confirming our expectation that developing countries could potentially experience regular encounters with wildlife. South Africa had more HWC cases than developed countries (e.g., in Australia and North America, yet the dichotomy between first world and third world economies in South Africa provides a regional exemplar of global patterns in HWC. Globally, HWC involved mainly mammals and birds, with carnivores and primates as the most high-scale conflict species and thus were a severely persecuted group. Our foundational research provides the first global assessment of HWC and showed that people in developing countries are vulnerable to HWC, perhaps related to reduced protection of livestock and crops against a larger guild of problem mammals. We suggest that a wider range of literature, including governmental and non-governmental publications, be surveyed to contribute to further research in this area of study.

Globalization, statist political economy, and unsuccessful education reform in South Korea, 1993-2003.

Directory of Open Access Journals (Sweden)

Ki Su Kim

2005-02-01

Full Text Available This article examines the relationship between globalization and national education reforms, especially those of educational systems. Instead of exploring the much debated issues of how globalization affects national educational systems and how the nations react by what kinds of systemic education reform, however, it focuses on what such a method often leaves out, viz., the internal conditions of a nation that facilitates or hampers reform efforts. Taking South Korea as an example, it explores that country's unique national context which restricts and even inhibits education reforms. Especially noted here is the established "statist" political economy in education. In the paper's analysis, although South Korea's statist political economy has made a substantial contribution to economic and educational development, it is now considered increasingly unviable as globalization progresses. Nevertheless, the internal conditions, resultant from the previous statist policies, set limits on policy makers' efforts to alter the existing educational system. The analysis suggests that a fuller assessment of globalization's impact upon national educational systems or their reforms requires a perspective which is broad enough to encompass not only the concepts and/or theories of globalization and nation states but also the power relations and ideological setup of individual nations.

Whether developed countries should make unilateral technology transfers to developing countries in order to address global environment problems is debatable. This paper discusses the issue in a framework that recognizing nations' joint production of environmental externalities. Unlike the existing literature on unilateral transfers, this paper presents a North-South environmental-economic optimal growth model that allows transfers to mitigate externalities only. The paper derives criteria that would make such transfers feasible. By solving the transfer problem in a modified RICE model [Nordhaus, W.D., Yang, Z., 1996. A regional dynamic general equilibrium model of alternative climate change strategies, Am. Econ. Rev., 86 (4) 741-65], this paper also provides information on the timing and the amount of unilateral transfers from North to South to address potential global warming problem, one major global environmental externality. A policy implication from his study is that moderate employment of unilateral transfers would benefit North along with the world as a whole

Not enough space for everyone: China and the competition for the Global South

Directory of Open Access Journals (Sweden)

Fernando Mouron

2016-12-01

Full Text Available A little more than a decade and a half into the “Asian century”, the epicentre of the global economy has moved from the North Atlantic towards East Asia at an unprecedented pace. As a correlate, China’s growing expansion at global level has been gradually undermining the position of leading regional powers such as Brazil and South Africa. The displacement of their investments and the consequent loss of their regional markets, added to the growth of other medium-sized regional powers through stronger links with Beijing, have damaged both countries prospects of regional leadership. From this perspective, in contrast to the abundant literature depicting China as a great opportunity for Brazil and South Africa, this paper warns that both countries’ regional importance has been diminished in favour of China, which calls the usefulness of the BRICS concept into question.

Landslides constitute a serious problem globally. Moreover, landslide impact remains underestimated especially in the Global South. It is precisely there where the largest impact is experienced. An overview of measures taken to reduce risk of landslides in the Global South is however still lacking. Because in many countries of the Global South disaster risk reduction (DRR) is at an emerging stage, it is crucial to monitor the ongoing efforts (e.g. discussions on the Post-2015 Framework for DRR). The first objective of this study is to make an inventory of techniques and strategies that are applied to reduce risk from landslides in tropical countries. The second objective is to investigate what are the main bottlenecks for implementation of DRR strategies. In order to achieve these objectives, a review of both scientific and grey literature was conducted, supplemented with expert knowledge. The compilation of recommended and implemented DRR measures from landslide-prone tropical countries is based on an adapted classification proposed by the SafeLand project. According to Vaciago (2013), landslide risk can be reduced by either reducing the hazard, the vulnerability, the number or value of elements at risk or by sharing the residual risk. In addition, these measures can be combined with education and/or awareness raising and are influenced by governance structures and cultural beliefs. Global landslide datasets have been used to identify landslide-prone countries, augmented with region-specific datasets. Countries located in the tropics were selected in order to include landslide-prone countries with a different Human Development Index (HDI) but with a similar climate. Preliminary results support the statement made by Anderson (2013) that although the importance of shifting from post-disaster emergency actions to pre-disaster mitigation is acknowledged, in practice this paradigm shift seems rather limited. It is expected that this is especially the case in countries

How are WEEE doing? A global review of the management of electrical and electronic wastes

Ongondo, F.O.; Williams, I.D.; Cherrett, T.J.

2011-01-01

This paper presents and critically analyses the current waste electrical and electronic equipment (WEEE) management practices in various countries and regions. Global trends in (i) the quantities and composition of WEEE; and (ii) the various strategies and practices adopted by selected countries to handle, regulate and prevent WEEE are comprehensively examined. The findings indicate that for (i), the quantities of WEEE generated are high and/or on the increase. IT and telecommunications equipment seem to be the dominant WEEE being generated, at least in terms of numbers, in Africa, in the poorer regions of Asia and in Latin/South America. However, the paper contends that the reported figures on quantities of WEEE generated may be grossly underestimated. For (ii), with the notable exception of Europe, many countries seem to be lacking or are slow in initiating, drafting and adopting WEEE regulations. Handling of WEEE in developing countries is typified by high rate of repair and reuse within a largely informal recycling sector. In both developed and developing nations, the landfilling of WEEE is still a concern. It has been established that stockpiling of unwanted electrical and electronic products is common in both the USA and less developed economies. The paper also identifies and discusses four common priority areas for WEEE across the globe, namely: (i) resource depletion; (ii) ethical concerns; (iii) health and environmental issues; and (iv) WEEE takeback strategies. Further, the paper discusses the future perspectives on WEEE generation, treatment, prevention and regulation. Four key conclusions are drawn from this review: global amounts of WEEE will continue unabated for some time due to emergence of new technologies and affordable electronics; informal recycling in developing nations has the potential of making a valuable contribution if their operations can be changed with strict safety standards as a priority; the pace of initiating and enacting WEEE

Full Text Available The maritime industry is the major enabler of international trade. Major economic events in the international arena such as global recessions affect world trade and therefore the maritime industry as well. South Africa imports and exports major commodities and products therefore such events will also affect the country's economy. This paper explores how different industries within the South African maritime industry have been affected by global economic recessions. As some of them are of great significance to the country's economy, it is imperative to look at how these industries are affected so as to be able to see the national impact.

Developing an ionospheric map for South Africa

Full Text Available The development of a map of the ionosphere over South Africa is presented in this paper. The International Reference Ionosphere (IRI model, South African Bottomside Ionospheric Model (SABIM, and measurements from ionosondes in the South African Ionosonde Network, were combined within their own limitations to develop an accurate representation of the South African ionosphere. The map is essentially in the form of a computer program that shows spatial and temporal representations of the South African ionosphere for a given set of geophysical parameters. A validation of the map is attempted using a comparison of Total Electron Content (TEC values derived from the map, from the IRI model, and from Global Positioning System (GPS measurements. It is foreseen that the final South African ionospheric map will be implemented as a Space Weather product of the African Space Weather Regional Warning Centre.

GLOBAL WARMING AND CLIMATE CHANGE IN SOUTH AMERICA

PATRICK PATERSON

2017-12-01

Full Text Available Global warming presents one of the most serious threats to South American nations. Countries in the region are at risk of a variety of climate change related problems: rising sea levels, diminishing potable water supplies, forest res, intense storms and ooding, heat waves and the spread of diseases. These disasters are occurring more frequently in the region and will likely increase in intensity also. The armed forces in the region are the only government departments with both the capacity and the manpower to respond to these massive catastrophes. Military support to civilian authorities will be required more frequently and under more severe conditions as climate change conditions worsen.

Global Distribution of Net Electron Acceptance in Subseafloor Sediment

Science.gov (United States)

Fulfer, V. M.; Pockalny, R. A.; D'Hondt, S.

2017-12-01

We quantified the global distribution of net electron acceptance rates (e-/m2/year) in subseafloor sediment (>1.5 meters below seafloor [mbsf]) using (i) a modified version of the chemical-reaction-rate algorithm by Wang et al. (2008), (ii) physical properties and dissolved oxygen and sulfate data from interstitial waters of sediment cores collected by the Ocean Drilling Program, Integrated Ocean Drilling Program, International Ocean Discovery Program, and U.S. coring expeditions, and (iii) correlation of net electron acceptance rates to global oceanographic properties. Calculated net rates vary from 4.8 x 1019 e-/m2/year for slowly accumulating abyssal clay to 1.2 x 1023 e-/m2/year for regions of high sedimentation rate. Net electron acceptance rate correlates strongly with mean sedimentation rate. Where sedimentation rate is very low (e.g., 1 m/Myr), dissolved oxygen penetrates more than 70 mbsf and is the primary terminal electron acceptor. Where sedimentation rate is moderate (e.g., 3 to 60 m/Myr), dissolved sulfate penetrates as far as 700 mbsf and is the principal terminal electron acceptor. Where sedimentation rate is high (e.g., > 60 m/Myr), dissolved sulfate penetrates only meters, but is the principal terminal electron acceptor in subseafloor sediment to the depth of sulfate penetration. Because microbial metabolism continues at greater depths than the depth of sulfate penetration in fast-accumulating sediment, complete quantification of subseafloor metabolic rates will require consideration of other chemical species.

The Asian Criminological Paradigm and How It Links Global North and South: Combining an Extended Conceptual Toolbox from the North with Innovative Asian Contexts

Jianhong Liu

2017-03-01

Full Text Available In their recent seminal paper ‘Southern Criminology’, Carrington, Hogg and Sozzo (2016 address the issue of the global divide between South/North relations in the hierarchal production of criminological knowledge. They point out that the divide privileges theories, assumptions and methods that are largely based on the empirical specificities of the global North. Carrington et al. contend that the dominance of global North criminology has led to a severe underdevelopment of criminology in the global South, except ‘in Asia, with the establishment of the Asian Criminological Society and its journal’ (Liu 2009, in Carrington et al. 2016: 3. Carrington et al. propose an important task of bridging the global divide through further developing criminology in the global South. My present paper reviews the development of Asian criminology under the framework of the Asian Criminological Paradigm (Liu 2009. I primarily review the conceptual and theoretical developments, to suggest strategies that can contribute to the task of bridging the gap between global North and South. What Asian criminology has done is expand the theoretical tool box originally developed in the global North through the strategies of transportation of theories, elaboration of theories, and proposing new concepts and theories based on the empirical grounds of Asian contexts.

Features of annual and semiannual variations derived from the global ionospheric maps of total electron content

Directory of Open Access Journals (Sweden)

B. Zhao

2008-01-01

Full Text Available In the present work we use the NASA-JPL global ionospheric maps of total electron content (TEC, firstly to construct TEC maps (TEC vs. magnetic local time MLT, and magnetic latitude MLAT in the interval from 1999 to 2005. These TEC maps were, in turn, used to estimate the annual-to-mean amplitude ratio, A₁, and the semiannual-to-mean amplitude ratio, A₂, as well as the latitudinal symmetrical and asymmetrical parts, A' and A" of A₁. Thus, we investigated in detail the TEC climatology from maps of these indices, with an emphasis on the quantitative presentation for local time and latitudinal changes in the seasonal, annual and semiannual anomalies of the ionospheric TEC. Then we took the TEC value at 14:00 LT to examine various anomalies at a global scale following the same procedure. Results reveal similar features appearing in NmF2, such as that the seasonal anomaly is more significant in the near-pole regions than in the far-pole regions and the reverse is true for the semiannual anomaly; the winter anomaly has least a chance to be observed at the South America and South Pacific areas. The most impressive feature is that the equinoctial asymmetry is most prominent at the East Asian and South Australian areas. Through the analysis of the TIMED GUVI columnar [O/N2] data, we have investigated to what extent the seasonal, annual and semiannual variations can be explained by their counterparts in [O/N2]. Results revealed that the [O/N2] variation is a major contributor to the daytime winter anomaly of TEC, and it also contributes to some of the semiannual and annual anomalies. The contribution to the anomalies unexplained by the [O/N2] data could possibly be due to the dynamics associated with thermospheric winds and electric fields.

Although neglected tropical diseases (NTDs) threaten the health of those living in the developing world, innovation directed toward addressing NTDs is comparatively meager. Health biotechnology firms in rapidly growing economies in the global South are developing and selling vaccines, diagnostics, and therapeutics for these diseases to local markets. In this paper we identify a pipeline of sixty-two NTD products from seventy-eight "Southern" companies. We also propose creation of a Global Health Accelerator-a new nonprofit organization whose mission would be to support and help grow this Southern source of affordable innovation for NTDs.

Topographic asymmetry of the South Atlantic from global models of mantle flow and lithospheric stretching

The relief of the South Atlantic is characterized by elevated passive continental margins along southern Africa and eastern Brazil, and by the bathymetric asymmetry of the southern oceanic basin where the western flank is much deeper than the eastern flank. We investigate the origin of these topographic features in the present and over time since the Jurassic with a model of global mantle flow and lithospheric deformation. The model progressively assimilates plate kinematics, plate boundaries and lithospheric age derived from global tectonic reconstructions with deforming plates, and predicts the evolution of mantle temperature, continental crustal thickness, long-wavelength dynamic topography, and isostatic topography. Mantle viscosity and the kinematics of the opening of the South Atlantic are adjustable parameters in multiple model cases. Model predictions are compared to observables both for the present-day and in the past. Present-day predictions are compared to topography, mantle tomography, and an estimate of residual topography. Predictions for the past are compared to tectonic subsidence from backstripped borehole data along the South American passive margin, and to dynamic uplift as constrained by thermochronology in southern Africa. Comparison between model predictions and observations suggests that the first-order features of the topography of the South Atlantic are due to long-wavelength dynamic topography, rather than to asthenospheric processes. We find the uplift of southern Africa to be best reproduced with a lower mantle that is at least 40 times more viscous than the upper mantle.

The South Asian Origins of the Global Network to Eradicate Blindness: WHO, NGOs, and Decentralization.

Science.gov (United States)

Williams, Logan D A

2018-03-01

The global network to eradicate blindness emerged out of the work of Western and South Asian professionals to eradicate smallpox which was endemic in South Asia. The history of the emergence of the global network to eradicate blindness demonstrates a shift from vertical command and control public health programs directed by the WHO, to the decentralized public health services originating in non-profit, non-governmental organizations and coordinated by the WHO. The WHO constitution started with a federal regionalist structure that encouraged collaboration and coordination with NGOs. In South Asia in particular, epidemiologists and general medical practitioners moved from eradicating smallpox through the WHO to creating their own domestic and international NGOs based in various countries with a mission to control blindness in South Asia and Africa. In 1975, pushed by the WHO Director General, these new NGOs in turn joined with individual ophthalmologists and existing blind member associations to form the International Agency for the Prevention of Blindness. Thus, the WHO was shaped by, and shaping, international NGOs such as the IAPB. The IAPB pushed for the formation of the WHO Prevention of Blindness program. This was the earliest example of how the IAPB facilitates bottom-up agenda-setting in the WHO. In 1980, when the WHO officially closed the smallpox program, the Prevention of Blindness program first received independent funding. Presently, the IAPB acts as a decentralized arm of the WHO.

Working with teams of "insiders": Qualitative approaches to data collection in the Global South

Enid Schatz

2015-02-01

Full Text Available Background: The convergence of two qualitative methodological strategies - working in "teams" and with "insiders" - can facilitate access, efficiency, and insights into research questions of interest to demographers. Even though this approach is becoming more common among population researchers in the Global South to address a range of research questions, little has been published that describes the method and critically assesses its strengths and weaknesses. Objective: We draw on three projects embedded in the Agincourt Health and Socio-Demographic Surveillance System site in rural South Africa that integrate both approaches to demonstrate the benefits and limitations of this strategy. Methods: We document, through in-depth description, how these three projects achieve access, efficiency, and insights into issues of population concern (HIV/AIDS, aging, and child wellbeing utilizing a "team-insider" approach by working with groups of local research assistants. Conclusions: The projects vary in their use of "teams" and "insiders" but collectively deepen our understanding of pressing population concerns in the Global South. In particular, by using teams of insiders, these projects gain insights into local ideas about HIV, uncover ways that HIV affects older women's lives, and provide in-depth understanding of children's social connections. The approach also presents a number of challenges, however, such as grappling with the responsibilities and burdens that are placed on local insider team members.

An Analysis of the Regulatory Environment Governing Hearsay Electronic Evidence in South Africa: Suggestions for Reform – Part One

Directory of Open Access Journals (Sweden)

Lee Swales

2018-03-01

Full Text Available The purpose of this two-part article is to examine the regulatory environment governing hearsay electronic evidence in South Africa – with a view to providing clear, practical suggestions for regulatory reform in the context of the South African Law Reform Commission's most recent Discussion Paper on electronic evidence. Technology has become an indispensable part of modern life. In particular, the Internet has facilitated new forms of business enterprise, and shifted basic communication norms. From a legal perspective, technology has presented several novel challenges for courts and legal practitioners to deal with – one of these key challenges relates to electronic evidence and in particular the application of the hearsay rules to the digital environment. The South African Law Reform Commission has identified the application of the hearsay rule as one of the core concerns with regard to electronic evidence, and certain academic analysis has revealed inefficiency in the current legal position which may involve multiple sources of law. Moreover, the Law Society of South Africa has stated that there is some confusion amongst members of the profession in relation to hearsay as it applies to electronic evidence. With the pervasive and burgeoning nature of technology, and with the Internet in mind, it is natural to assume that electronic evidence will be relevant in most forms of legal proceedings in future, and hearsay electronic evidence in particular will play an increasingly important role in years to come. Consequently, part one of this article will consider the key definitional concept in relation to electronic evidence – data messages - and examine whether the definition should be revised. In addition, part one of this article will answer two further critical questions posed by the South African Law Reform Commission in relation to data messages and hearsay evidence, namely: should a data message constitute hearsay? And, how should one

Towards global Guinea worm eradication in 2015: the experience of South Sudan.

Science.gov (United States)

Awofeso, Niyi

2013-08-01

For centuries, the Guinea worm parasite (Dracunculus medinensis) has caused disabling misery, infecting people who drink stagnant water contaminated with the worm's larvae. In 2012, there were 542 cases of Guinea worm reported globally, of which 521 (96.1%) were reported in South Sudan. Protracted civil wars, an inadequate workforce, neglect of potable water provision programs, suboptimal Guinea worm surveillance and case containment, and fragmented health systems account for many of the structural and operational factors encumbering South Sudan's Guinea worm eradication efforts. This article reviews the impacts of six established Guinea worm control strategies in South Sudan: (1) surveillance to determine actual caseload distribution and trends in response to control measures; (2) educating community members from whom worms are emerging to avoid immersing affected parts in sources of drinking water; (3) filtering potentially contaminated drinking water using cloth filters or filtered drinking straws; (4) treating potentially contaminated surface water with the copepod larvicide temephos (Abate); (5) providing safe drinking water from boreholes or hand-dug wells; and (6) containment of transmission through voluntary isolation of each patient to prevent contamination of drinking water sources, provision of first aid, and manual extraction of the worm. Surveillance, community education, potable water provision, and case containment remain weak facets of the program. Abate pesticide is not a viable option for Guinea worm control in South Sudan. In light of current case detection and containment trends, as well as capacity building efforts for Guinea worm eradication, South Sudan is more likely to eradicate Guinea worm by 2020, rather than by 2015. The author highlights areas in which substantial improvements are required in South Sudan's Guinea worm eradication program, and suggests improvement strategies.

The global village in a local context. Implementing global awareness as a managerial competency within South Africa's multicultural mainstream media newsrooms

Directory of Open Access Journals (Sweden)

E. Steyn

2006-12-01

Full Text Available Purpose: As part of a national research survey into the importance and implementation of six managerial competencies, this article aims to investigate the importance a national sample of reporters and first-line newsroom managers in South Africa's mainstream media attach to global awareness as a managerial competency. It also aims to establish gaps between the importance attached to and current implementation thereof by the latter. Design/Methodology/Approach: Qualitative and quantitative research designs were combined to obtain the most comprehensive view on the research problem. Quantitative data was compiled through self-administered questionnaires among first-line newsroom managers and reporters employed by the country's mainstream media. Qualitative data was obtained through semi-structured interviews and observational research. These sets of data were combined triangularly to improve validity and reliability. Quantitative data was analysed through factor analysis and effect size analysis, while qualitative data was analysed through qualitative content analysis. Findings: It was found that both respondent groups perceive first-line newsroom managers unable to implement the skills associated with the global awareness competency (given the importance they attach to it. While in some cases first-line newsroom managers themselves were more aware of their shortcomings, reporters highlighted other instances where they perceive their superiors unable to perform as expected. Implications: Given the challenges associated with globalisation, media managers need skills to identify and realise the impact of national and international changes on their business activities. South African media managers must also identify and address the challenges associated with the multilingual and multicultural backgrounds of their newsroom staff. Originality/Value: The dimensions of global awareness as a managerial competency are rooted in general management theory

Electronic Referrals and Digital Imaging Systems in Ophthalmology: A Global Perspective.

Science.gov (United States)

Jeganathan, V Swetha E; Hall, H Nikki; Sanders, Roshini

2017-01-01

Ophthalmology departments face intensifying pressure to expedite sight-saving treatments and reduce the global burden of disease. The use of electronic communication systems, digital imaging, and redesigned service care models is imperative for addressing such demands. The recently developed Scottish Eyecare Integration Project involves an electronic referral system from community optometry to the hospital ophthalmology department using National Health Service (NHS) email with digital ophthalmic images attached, via a virtual private network connection. The benefits over the previous system include reduced waiting times, improved triage, e-diagnosis in 20% without the need for hospital attendance, and rapid electronic feedback to referrers. We draw on the experience of the Scottish Eyecare Integration Project and discuss the global applications of this and other advances in teleophthalmology. We focus particularly on the implications for management and screening of chronic disease, such as glaucoma and diabetic eye disease, and ophthalmic disease, such as retinopathy of prematurity where diagnosis is almost entirely and critically dependent on fundus appearance. Currently in Scotland, approximately 75% of all referrals are electronic from community to hospital. The Scottish Eyecare Integration Project is globally the first of its kind and unique in a national health service. Such speedy, safe, and efficient models of communication are geographically sensitive to service provision, especially in remote and rural regions. Along with advances in teleophthalmology, such systems promote the earlier detection of sight-threatening disease and safe follow-up of non-sight-threatening disease in the community.

Local-to-Global (L-G) Monte Carlo methods are a way to make three-dimensional electron transport both fast and accurate relative to other Monte Carlo methods. This is achieved by breaking the simulation into two stages: a local calculation done over small geometries having the size and shape of the ''steps'' to be taken through the mesh; and a global calculation which relies on a stepping code that samples the stored results of the local calculation. The increase in speed results from taking fewer steps in the global calculation than required by ordinary Monte Carlo codes and by speeding up the calculation per step. The potential for accuracy comes from the ability to use long runs of detailed codes to compile probability distribution functions (PDFs) in the local calculation. Specific examples of successful Local-to-Global algorithms are given

Full Text Available The Universal Declaration of Bioethics and Human Rights (UDBHR of the United Nations Educational, Scientific and Cultural Organization (UNESCO was adopted unanimously in 2005 by the world community as a universal guideline, according to which members of the global community were accountable to each other. Research results from UNESCO show that the UDBHR has had little or no impact in South Africa (SA. The primary objective of this article is to promote awareness of the UDBHR in SA and Africa by focusing on Article 9 of the Declaration, which accepts the right to privacy and confidentiality. For this objective to be relevant in the SA context, depends on whether the guidelines of the National Department of Health’s Ethics in Health Research: Principles, Processes and Structures of 2015 acknowledge biobanks of the universally accepted ethical guidelines on privacy and confidentiality of autonomous persons and whether these guidelines are broadly in accordance with global bioethical guidelines.

The self as capital in the narrative economy: how biographical testimonies move activism in the Global South.

Science.gov (United States)

Burchardt, Marian

2016-05-01

This article analyses and theorises the practice of biographical storytelling of HIV-positive AIDS activists in South Africa. Combining research in illness narratives, studies of emotions in social activism and analysis of global health institutions in Africa, I explore how biographical self-narrations are deployed to facilitate access to resources and knowledge and thus acquire material and symbolic value. I illustrate my argument through the analysis of the case of an AIDS activist who became a professional biographical storyteller. Based on the analysis which I claim to represent wider dynamics in human-rights-based health activism in the Global South, I propose the concept of narrative economies by which I mean the set of exchange relationships within which biographical self-narrations circulate and produce social value for individuals and organisations. © 2015 Foundation for the Sociology of Health & Illness.

Global warming and South Indian monsoon rainfall-lessons from the Mid-Miocene.

Science.gov (United States)

Reuter, Markus; Kern, Andrea K; Harzhauser, Mathias; Kroh, Andreas; Piller, Werner E

2013-04-01

Precipitation over India is driven by the Indian monsoon. Although changes in this atmospheric circulation are caused by the differential seasonal diabatic heating of Asia and the Indo-Pacific Ocean, it is so far unknown how global warming influences the monsoon rainfalls regionally. Herein, we present a Miocene pollen flora as the first direct proxy for monsoon over southern India during the Middle Miocene Climate Optimum. To identify climatic key parameters, such as mean annual temperature, warmest month temperature, coldest month temperature, mean annual precipitation, mean precipitation during the driest month, mean precipitation during the wettest month and mean precipitation during the warmest month the Coexistence Approach is applied. Irrespective of a ~ 3-4 °C higher global temperature during the Middle Miocene Climate Optimum, the results indicate a modern-like monsoonal precipitation pattern contrasting marine proxies which point to a strong decline of Indian monsoon in the Himalaya at this time. Therefore, the strength of monsoon rainfall in tropical India appears neither to be related to global warming nor to be linked with the atmospheric conditions over the Tibetan Plateau. For the future it implies that increased global warming does not necessarily entail changes in the South Indian monsoon rainfall.

Supplier Partnership Strategy and Global Competitiveness: A Case of Samsung Electronics

Jangwoo Lee

2015-11-01

Full Text Available Samsung Group has accelerated its management innovation process, following the announcement of ‘New Management’ by the CEO Lee Kun-Hee. Particular attention must be paid to the smart-phone business of Samsung Electronics, which is the core company of the Samsung Group. In 2009, as Apple entered into the Korean market, the domestic smart-phone market faced the so called ‘Apple Shock’ due to its choice of a monopolistic and closed operating system. In response, Samsung Electronics introduced the innovative Galaxy series, replacing the old model of Omnia series. This move reaped dramatic success by dominating the world smart-phone market. Samsung Electronics ranked first in the 2012 world smart-phone market, and in 2013 it sold over 300 million devices for the first time in history, thereby solidifying the number one spot with a market share of 32.3%. Samsung Electronics’ achievement in its management innovation process was successful, due to its internal innovation and its partnership with sub-suppliers. Samsung Electronics strengthened its supplier partnership strategy, which in turn, led to an internalization of subparts assembly and process technology. By conducting the final assembly process on its own, it established the global supply chain that accompanies a high level of efficiency and operational elasticity. Samsung Electronics successfully systemized several hundred suppliers into an effective partnership and created an eco system where cooperation and competition can co-exist in its supply chain network. In sum, Samsung Electronics has successfully created the Samsung Production System that brings an economy of scale and allows prompt response. On the other hand, Apple did not get involved with subparts production, besides design and product design. This research identifies the effectiveness of Samsung Electronics’ supplier partnerships in its global competitiveness by examining characteristics of supplier partnership

Global environmental policy strategies. ''Environment and development'' in north-south relations

International Nuclear Information System (INIS)

Bruckmeier, K.

1994-01-01

Global environmental policy has hardly made headway after the United Nations World Conference on Environment and Development (UNCED) in Rio in June 1992, despite there being no shortage of programmes, institutions, and actors. Obviously, formal structures for political action based on the system of institutions of the United Nations do not suffice. Global environmental policy strategies must reach further, overcoming system-immanent obstacles to sustainable development. This necessitates analyzing the causes of environmental destruction and making a critical evaluation of the relations between the societies of the North and South that received their imprint from development policies. Only after such a preliminary elucidation by interdisciplinary approaches in the light of political and ecological economy and human ecology does an empirical analysis of politically controlled processes in environmental and development policy make sense. The analysis points to strategies for this international political field that rely on non-governmental actors and social movements, and question the traditional European model of an environmental policy determined by government institutions.

The Role of Atmospheric Heating over the South China Sea and Western Pacific Regions in Modulating Asian Summer Climate under the Global Warming Background

Science.gov (United States)

He, B.

2015-12-01

Global warming is one of the most significant climate change signals at the earth's surface. However, the responses of monsoon precipitation to global warming show very distinct regional features, especially over the South China Sea (SCS) and surrounding regions during boreal summer. To understand the possible dynamics in these specific regions under the global warming background, the changes in atmospheric latent heating and their possible influences on global climate are investigated by both observational diagnosis and numerical sensitivity simulations. Results indicate that summertime latent heating has intensified in the SCS and western Pacific, accompanied by increased precipitation, cloud cover, lower-tropospheric convergence, and decreased sea level pressure. Sensitivity experiments show that middle and upper tropospheric heating causes an east-west feedback pattern between SCS-western Pacific and South Asia, which strengthens the South Asian High in the upper troposphere and moist convergence in the lower troposphere, consequently forcing a descending motion and adiabatic warming over continental South Asia and leading to a warm and dry climate. When air-sea interaction is considered, the simulation results are overall more similar to observations, and in particular the bias of precipitation over the Indian Ocean simulated by AGCMs has been reduced. The results highlight the important role of latent heating in adjusting the changes in sea surface temperature through atmospheric dynamics.

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

Global view of F-region electron density and temperature at solar maximum

International Nuclear Information System (INIS)

Brace, L.H.; Theis, R.F.; Hoegy, W.R.

1982-01-01

Dynamics Explorer-2 is permitting the first measurements of the global structure of the F-regions at very high levels of solar activity (S>200). Selected full orbits of Langmuir probe measurements of electron temperature, T/sub e/, and density, N/sub e/, are shown to illustrate this global structure and some of the ionospheric features that are the topic of other papers in this issue. The ionospheric thermal structure is of particular interest because T/sub e/ is a sensitive indicator of the coupling of magnetospheric energy into the upper atmosphere. A comparison of these heating effects with those observed at solar minimum shows that the magnetospheric sources are more important at solar maximum, as might have been expected. Heating at the cusp, the auroral oval and the plasma-pause is generally both greater and more variable. Electron cooling rate calculations employing low latitude measurements indicate that solar extreme ultraviolet heating of the F region at solar maximum is enhanced by a factor that is greater than the increase in solar flux. Some of this enhanced electron heating arises from the increase in electron heating efficiency at the higher N/sub e/ of solar maximum, but this appears insufficient to completely resolve the discrepancy

South-South cooperation in health: bringing in theory, politics, history, and social justice.

Birn, Anne-Emanuelle; Muntaner, Carles; Afzal, Zabia

2017-10-02

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

Mechanism of ENSO influence on the South Asian monsoon rainfall in global model simulations

Science.gov (United States)

Joshi, Sneh; Kar, Sarat C.

2018-02-01

Coupled ocean atmosphere global climate models are increasingly being used for seasonal scale simulation of the South Asian monsoon. In these models, sea surface temperatures (SSTs) evolve as coupled air-sea interaction process. However, sensitivity experiments with various SST forcing can only be done in an atmosphere-only model. In this study, the Global Forecast System (GFS) model at T126 horizontal resolution has been used to examine the mechanism of El Niño-Southern Oscillation (ENSO) forcing on the monsoon circulation and rainfall. The model has been integrated (ensemble) with observed, climatological and ENSO SST forcing to document the mechanism on how the South Asian monsoon responds to basin-wide SST variations in the Indian and Pacific Oceans. The model simulations indicate that the internal variability gets modulated by the SSTs with warming in the Pacific enhancing the ensemble spread over the monsoon region as compared to cooling conditions. Anomalous easterly wind anomalies cover the Indian region both at 850 and 200 hPa levels during El Niño years. The locations and intensity of Walker and Hadley circulations are altered due to ENSO SST forcing. These lead to reduction of monsoon rainfall over most parts of India during El Niño events compared to La Niña conditions. However, internally generated variability is a major source of uncertainty in the model-simulated climate.

Full Text Available The paper presents the analysis of South Africa’s BRICS Presidency which formally started with the summit in Durban on March 15-17, 2013 and finished in June 2014 with the BRICS leaders’ Fortaleza meeting. To assess the Presidency effectiveness the author applies “supply-demand” model fine-tuned to achieve a balance of external conditions and national priorities of the country chairing informal summitry institutions, such as BRICS, G20 or G7/8. This analytical paradigm allows reveal to what extent the Presidency has managed to ensure: 1 a high level of response to the key global governance challenges in the summit agenda and decisions; 2 a balance between internal demand (domestic priorities and external demand (other members’ interests and global governance challenges in the Presidency priorities; 3 maximal use of the institution’s capabilities. Conformity of the role chosen by the Presidency (organizer, mediator, political leader, national representative to the combination of external and internal conditions is also considered as it is a major factor of the presidency success. Content analysis, comparative analysis and functional approach were used in the study. The primary sources of the research included the BRICS documents, national documents of the member states, the leaders’ addresses. The study reveals that the major factors of the South African BRICS presidency success were commitment to implementation of the Durban decisions and action plan as well as the will to utilize the BRICS capabilities for African countries development and South African regional leadership. In the former case the foundation of success was reinforced the chair’ choice of the organizer role, whereas in the latter a combination of the political leader and national representative roles proved to be the most productive for the presidency.

Reconstructing Regional Ionospheric Electron Density: A Combined Spherical Slepian Function and Empirical Orthogonal Function Approach

Science.gov (United States)

Farzaneh, Saeed; Forootan, Ehsan

2018-03-01

The computerized ionospheric tomography is a method for imaging the Earth's ionosphere using a sounding technique and computing the slant total electron content (STEC) values from data of the global positioning system (GPS). The most common approach for ionospheric tomography is the voxel-based model, in which (1) the ionosphere is divided into voxels, (2) the STEC is then measured along (many) satellite signal paths, and finally (3) an inversion procedure is applied to reconstruct the electron density distribution of the ionosphere. In this study, a computationally efficient approach is introduced, which improves the inversion procedure of step 3. Our proposed method combines the empirical orthogonal function and the spherical Slepian base functions to describe the vertical and horizontal distribution of electron density, respectively. Thus, it can be applied on regional and global case studies. Numerical application is demonstrated using the ground-based GPS data over South America. Our results are validated against ionospheric tomography obtained from the constellation observing system for meteorology, ionosphere, and climate (COSMIC) observations and the global ionosphere map estimated by international centers, as well as by comparison with STEC derived from independent GPS stations. Using the proposed approach, we find that while using 30 GPS measurements in South America, one can achieve comparable accuracy with those from COSMIC data within the reported accuracy (1 × 1011 el/cm3) of the product. Comparisons with real observations of two GPS stations indicate an absolute difference is less than 2 TECU (where 1 total electron content unit, TECU, is 1016 electrons/m2).

Zn deficiency may be widespread in Asian countries such as South Korea. However, dietary habits have changed in response to rapid economic growth and globalization. Zn nutrition in South Koreans has therefore been assessed during a period (1969-1998) of unprecedented economic growth. Cross-sectional food consumption data from the Korean National Nutrition Survey Reports (KNNSR) of South Korea at four separate time points (1969, 1978, 1988 and 1998) were used to calculate Zn, Ca and phytate intakes using various food composition tables, databases and literature values. Nutrient values in local foods were cited from their analysed values. Average Zn intake was 5.8, 4.8 and 5.3 mg/d for 1969, 1978 and 1988 respectively, increasing to 7.3 mg/d in 1998 (73 % of the Korean Dietary Reference Intake). The phytate:Zn molar ratio decreased from 21 to 8 during the study period. Dietary Zn depletion due to marked decreases in cereal consumption, particularly barley which has a low Zn bioavailability, was counterbalanced by marked increases in the consumption of meat and fish, which are also Zn-rich foods. Reduced phytate consumption coincident with increased Zn intake suggests that Zn bioavailability also improved, particularly by 1998. Although total Zn intake was not greatly affected over the initial period of economic growth in South Korea (1969-1988), Zn contributions from different food sources changed markedly and both Zn intake and potential bioavailability were improved by 1998. The study may have implications for Zn nutrition in other Asian countries currently experiencing rapid economic growth.

Total electron content responses to HILDCAAs and geomagnetic storms over South America

2017-12-01

Total electron content (TEC) is extensively used to monitor the ionospheric behavior under geomagnetically quiet and disturbed conditions. This subject is of greatest importance for space weather applications. Under disturbed conditions the two main sources of electric fields, which are responsible for changes in the plasma drifts and for current perturbations, are the short-lived prompt penetration electric fields (PPEFs) and the longer-lasting ionospheric disturbance dynamo (DD) electric fields. Both mechanisms modulate the TEC around the globe and the equatorial ionization anomaly (EIA) at low latitudes. In this work we computed vertical absolute TEC over the low latitude of South America. The analysis was performed considering HILDCAA (high-intensity, long-duration, continuous auroral electrojet (AE) activity) events and geomagnetic storms. The characteristics of storm-time TEC and HILDCAA-associated TEC will be presented and discussed. For both case studies presented in this work (March and August 2013) the HILDCAA event follows a geomagnetic storm, and then a global scenario of geomagnetic disturbances will be discussed. Solar wind parameters, geomagnetic indices, O / N2 ratios retrieved by GUVI instrument onboard the TIMED satellite and TEC observations will be analyzed and discussed. Data from the RBMC/IBGE (Brazil) and IGS GNSS networks were used to calculate TEC over South America. We show that a HILDCAA event may generate larger TEC differences compared to the TEC observed during the main phase of the precedent geomagnetic storm; thus, a HILDCAA event may be more effective for ionospheric response in comparison to moderate geomagnetic storms, considering the seasonal conditions. During the August HILDCAA event, TEC enhancements from ˜ 25 to 80 % (compared to quiet time) were observed. These enhancements are much higher than the quiet-time variability observed in the ionosphere. We show that ionosphere is quite sensitive to solar wind forcing and

The global warming debate has sparked many facts activities in almost all sectors of human endeavors. There are the hard facts, the measurements of the greenhouse gases, the statistics of human activities responsible for emissions, the demographic figures. There are the soft facts, the interpretations of the hard facts requiring additional assumptions. There are the media, the press, television, for whom environmental problems make good stories, these can be used to rise emotions, to make heroes and antiheroes. There are politicians, the global warming debate can be used even in electron campaigns. Global warming is a topic within and beyond science. The judgment (and hence use) of scientific facts is overwhelmingly influenced by the ``Weltbild`` (underlying beliefs how the world operates), and consequently opposing positions of well-known scientists arise. There are the attempts to invent futures of man on Earth: policies, regulations, laws on nation, international, and global levels shall facilitate a change in the basic behavior of all men. The global warming issue has many facets and cannot be successfully discussed without including, e.g., the North-South dialogue, world population, etc.

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

Science.gov (United States)

Crush, Jonathan; Chikanda, Abel

2015-01-01

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

Ramesh Babu, Balakrishnan; Parande, Anand Kuber; Ahmed Basha, Chiya

2007-08-01

The production of electrical and electronic equipment (EEE) is one of the fastest growing global manufacturing activities. This development has resulted in an increase of waste electric and electronic equipment (WEEE). Rapid economic growth, coupled with urbanization and growing demand for consumer goods, has increased both the consumption of EEE and the production of WEEE, which can be a source of hazardous wastes that pose a risk to the environment and to sustainable economic growth. To address potential environmental problems that could stem from improper management of WEEE, many countries and organizations have drafted national legislation to improve the reuse, recycling and other forms of material recovery from WEEE to reduce the amount and types of materials disposed in landfills. Recycling of waste electric and electronic equipment is important not only to reduce the amount of waste requiring treatment, but also to promote the recovery of valuable materials. EEE is diverse and complex with respect to the materials and components used and waste streams from the manufacturing processes. Characterization of these wastes is of paramount importance for developing a cost-effective and environmentally sound recycling system. This paper offers an overview of electrical and e-waste recycling, including a description of how it is generated and classified, strategies and technologies for recovering materials, and new scientific developments related to these activities. Finally, the e-waste recycling industry in India is also discussed.

This research is an attempt to conceptualize the underlying forces behind persistent and ubiquitous problems of inequality in access to water in cities of the global south. Inequality in water access is hypothesized to result from urban water regimes that tend to prioritize the right to water access or to provide preferential terms of access for some groups in society, while marginalizing others. By employing a critical realist approach, different theories in relation to inequality are app...

South-South Cooperation, North-South Aid and the Prospect of International Aid Architecture

Directory of Open Access Journals (Sweden)

Meibo Huang

2015-12-01

Full Text Available South-South Cooperation (SSC and North-South Aid (NSA arise from different historical conditions and there are great differences between their philosophies, principles and paradigms. Against the background of a changing global environment, developed countries realized that the original development aid architecture must be reformed on one hand, and that developing countries are increasingly important in the aid architecture on the other. Hence, Western donors began to rethink their aid principles and methods, and accepted the concept of development effectiveness gradually, an attempt to establish global development forum and global partnership including emerging donors, beneficiary countries, civil society and the private sector. Nevertheless, being developing countries themselves, emerging donors are faced with unsolved domestic poverty issues and imperfect aid management institutions, which means that the emerging donors are unable to take a dominant position in the current aid architecture. Hence, the future dialogue and cooperation between traditional and emerging donors should feature the principle that the responsibilities taken by each party are collective but not identical, with developing countries bearing the main responsibilities in promoting poverty reduction and economic development in developing countries. They should be mutually tolerant about the different philosophies and share useful experiences. Moreover, emerging donors should promote development capacity building in recipient countries through win-win cooperation and solve their domestic development issues at the same time.

Global environmental policy strategies. ''Environment and development'' in north-south relations. Strategien globaler Umweltpolitik. ''Umwelt und Entwicklung'' in den Nord-Sued-Beziehungen

1994-01-01

Global environmental policy has hardly made headway after the United Nations World Conference on Environment and Development (UNCED) in Rio in June 1992, despite there being no shortage of programmes, institutions, and actors. Obviously, formal structures for political action based on the system of institutions of the United Nations do not suffice. Global environmental policy strategies must reach further, overcoming system-immanent obstacles to sustainable development. This necessitates analyzing the causes of environmental destruction and making a critical evaluation of the relations between the societies of the North and South that received their imprint from development policies. Only after such a preliminary elucidation by interdisciplinary approaches in the light of political and ecological economy and human ecology does an empirical analysis of politically controlled processes in environmental and development policy make sense. The analysis points to strategies for this international political field that rely on non-governmental actors and social movements, and question the traditional European model of an environmental policy determined by government institutions.

2016-05-01

The response of monsoon precipitation to global warming, which is one of the most significant climate change signals at the earth's surface, exhibits very distinct regional features, especially over the South China Sea (SCS) and adjacent regions in boreal summer. To understand the possible atmospheric dynamics in these specific regions under the global warming background, changes in atmospheric heating and their possible influences on Asian summer climate are investigated by both observational diagnosis and numerical simulations. Results indicate that heating in the middle troposphere has intensified in the SCS and western Pacific regions in boreal summer, accompanied by increased precipitation, cloud cover, and lower-tropospheric convergence and decreased sea level pressure. Sensitivity experiments show that middle and upper tropospheric heating causes an east-west feedback pattern between SCS and western Pacific and continental South Asia, which strengthens the South Asian High in the upper troposphere and moist convergence in the lower troposphere, consequently forcing a descending motion and adiabatic warming over continental South Asia. When air-sea interaction is considered, the simulation results are overall more similar to observations, and in particular the bias of precipitation over the Indian Ocean simulated by AGCMs has been reduced. The result highlights the important role of air-sea interaction in understanding the changes in Asian climate.

[Health, globalization and interculturalism: an anthropological approach to the situation of indigenous peoples in South America].

Hita, Susana Ramírez

2014-10-01

This article reflects upon the impact of globalization and interculturalism on the living conditions of indigenous peoples in South America. Through two examples - Bolivia and Argentina - it is seen how health interculturalism has transformed into a discourse and a practice that both global organizations and most Latin American countries have used to assimilate and attract indigenous communities. Traditional medicine is respected and valued without proposing changes to improve the living conditions of these population groups. This is especially true in those areas where land is being expropriated or contaminated with the extraction of gas, oil, minerals and the construction of dams, along with indiscriminate deforestation of the rainforest. Health/illness cannot be separated from the territorial conditions of these peoples since environmental health is critical for their survival.

Global evolution of Equidae and Gomphotheriidae from South America.

Prado, José L; Alberdi, María T

2014-08-01

The contemporary South American mammalian communities were determined by the emergence of the Isthmus of Panama and by the profound climatic oscillations during the Pleistocene. Horses and gomphotheres were 2 very conspicuous groups of immigrant mammals from North America that arrived in South America during the Pleistocene. The present study compiles updated data on the phylogeny, systematics and ecology of both groups in South America. The horses in South America are represented by 2 genera, Hippidion and Equus, as are the gomphotheres, represented by Cuvieronius and Stegomastodon. Both genera of horses include small (Hippidion devillei, H. saldiasi, E. andium and E. insulatus) and large forms (Equus neogeus and H. principale), which dispersed into South America using 2 different routes. The possible model for this dispersion indicates that the small forms used the Andes corridor, while larger horses dispersed through the eastern route and through some coastal areas. In the case of gomphotheres, Cuvieronius and Stegomastodon reached South America in 2 independent dispersal events, and Cuvieronius dispersed across the Andean corridor, while large Stegomastodon spread along the eastern route. Horses and gomphotheres present values of δ(13) C from woodlands to C4 grasslands. Hippidion present lower values of δ(13) C than Equus in the late Pleistocene, whereas the gomphotheres diverge from value of δ(18) O, reflecting that Cuvieronius inhabited the Andean corridor and Stegomastodon dispersed through eastern plains. The gomphothere and horse species recorded in South America became extinct around the time that humans arrived. © 2013 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

We estimate the global Hg wildfire emissions for the 2000s and the potential impacts from the 2000-2050 changes in climate, land use and land cover and Hg anthropogenic emissions by combining statistical analysis with global data on vegetation type and coverage as well as fire activities. Global Hg wildfire emissions are estimated to be 612 Mg year-1. Africa is the dominant source region (43.8% of global emissions), followed by Eurasia (31%) and South America (16.6%). We find significant perturbations to wildfire emissions of Hg in the context of global change, driven by the projected changes in climate, land use and land cover and Hg anthropogenic emissions. 2000-2050 climate change could increase Hg emissions by 14% globally and regionally by 18% for South America, 14% for Africa and 13% for Eurasia. Projected changes in land use by 2050 could decrease the global Hg emissions from wildfires by 13% mainly driven by a decline in African emissions due to significant agricultural land expansion. Future land cover changes could lead to significant increases in Hg emissions over some regions (+32% North America, +14% Africa, +13% Eurasia). Potential enrichment of terrestrial ecosystems in 2050 in response to changes in Hg anthropogenic emissions could increase Hg wildfire emissions globally (+28%) and regionally (+19% North America, +20% South America, +24% Africa, +41% Eurasia). Our results indicate that the future evolution of climate, land use and land cover and Hg anthropogenic emissions are all important factors affecting Hg wildfire emissions in the coming decades.

Total electron content responses to HILDCAAs and geomagnetic storms over South America

2017-12-01

Full Text Available Total electron content (TEC is extensively used to monitor the ionospheric behavior under geomagnetically quiet and disturbed conditions. This subject is of greatest importance for space weather applications. Under disturbed conditions the two main sources of electric fields, which are responsible for changes in the plasma drifts and for current perturbations, are the short-lived prompt penetration electric fields (PPEFs and the longer-lasting ionospheric disturbance dynamo (DD electric fields. Both mechanisms modulate the TEC around the globe and the equatorial ionization anomaly (EIA at low latitudes. In this work we computed vertical absolute TEC over the low latitude of South America. The analysis was performed considering HILDCAA (high-intensity, long-duration, continuous auroral electrojet (AE activity events and geomagnetic storms. The characteristics of storm-time TEC and HILDCAA-associated TEC will be presented and discussed. For both case studies presented in this work (March and August 2013 the HILDCAA event follows a geomagnetic storm, and then a global scenario of geomagnetic disturbances will be discussed. Solar wind parameters, geomagnetic indices, O ∕ N2 ratios retrieved by GUVI instrument onboard the TIMED satellite and TEC observations will be analyzed and discussed. Data from the RBMC/IBGE (Brazil and IGS GNSS networks were used to calculate TEC over South America. We show that a HILDCAA event may generate larger TEC differences compared to the TEC observed during the main phase of the precedent geomagnetic storm; thus, a HILDCAA event may be more effective for ionospheric response in comparison to moderate geomagnetic storms, considering the seasonal conditions. During the August HILDCAA event, TEC enhancements from  ∼  25 to 80 % (compared to quiet time were observed. These enhancements are much higher than the quiet-time variability observed in the ionosphere. We show that ionosphere is quite sensitive to

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

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

Global geopotential models (GGMs) are vital in computing global geoid undulations heights. Based on the ellipsoidal height by Global Navigation Satellite System (GNSS) observations, the accurate orthometric height can be calculated by adding precise and accurate geoid undulations model information. However, GGMs also provide data from the satellite gravity missions such as GRACE, GOCE and CHAMP. Thus, this will assist to enhance the global geoid undulations data. A statistical assessment has been made between geoid undulations derived from 4 GGMs and the airborne gravity data provided by Department of Survey and Mapping Malaysia (DSMM). The goal of this study is the selection of the best possible GGM that best matches statistically with the geoid undulations of airborne gravity data under the Marine Geodetic Infrastructures in Malaysian Waters (MAGIC) Project over marine areas in Sabah. The correlation coefficients and the RMS value for the geoid undulations of GGM and airborne gravity data were computed. The correlation coefficients between EGM 2008 and airborne gravity data is 1 while RMS value is 0.1499.In this study, the RMS value of EGM 2008 is the lowest among the others. Regarding to the statistical analysis, it clearly represents that EGM 2008 is the best fit for marine geoid undulations throughout South China Sea.

Formation of mantle "lone plumes" in the global downwelling zone - A multiscale modelling of subduction-controlled plume generation beneath the South China Sea

Science.gov (United States)

Zhang, Nan; Li, Zheng-Xiang

2018-01-01

It has been established that almost all known mantle plumes since the Mesozoic formed above the two lower mantle large low shear velocity provinces (LLSVPs). The Hainan plume is one of the rare exceptions in that instead of rising above the LLSVPs, it is located within the broad global mantle downwelling zone, therefore classified as a "lone plume". Here, we use the Hainan plume example to investigate the feasibility of such lone plumes being generated by subducting slabs in the mantle downwelling zone using 3D geodynamic modelling. Our geodynamic model has a high-resolution regional domain embedded in a relatively low resolution global domain, which is set up in an adaptive-mesh-refined, 3D mantle convection code ASPECT (Advanced Solver for Problems in Earth's ConvecTion). We use a recently published plate motion model to define the top mechanical boundary condition. Our modelling results suggest that cold slabs under the present-day Eurasia, formed from the Mesozoic subduction and closure of the Tethys oceans, have prevented deep mantle hot materials from moving to the South China Sea from regions north or west of the South China Sea. From the east side, the Western Pacific subduction systems started to promote the formation of a lower-mantle thermal-chemical pile in the vicinity of the future South China Sea region since 70 Ma ago. As the top of this lower-mantle thermal-chemical pile rises, it first moved to the west, and finally rested beneath the South China Sea. The presence of a thermochemical layer (possible the D″ layer) in the model helps stabilizing the plume root. Our modelling is the first implementation of multi-scale mesh in the regional model. It has been proved to be an effective way of modelling regional dynamics within a global plate motion and mantle dynamics background.

Globally, the East Asian monsoon region is one of the richest environments in terms of biodiversity. The region is undergoing rapid human development, yet its river ecosystems have not been well studied. Global warming represents a major challenge to the survival of species in this region and makes it necessary to assess and reduce the potential consequences of warming on species of conservation concern. We projected the effects of global warming on stream insect (Ephemeroptera, Odonata, Plecoptera, and Trichoptera [EOPT]) diversity and predicted the changes of geographical ranges for 121 species throughout South Korea. Plecoptera was the most sensitive (decrease of 71.4% in number of species from the 2000s through the 2080s) order, whereas Odonata benefited (increase of 66.7% in number of species from the 2000s through the 2080s) from the effects of global warming. The impact of global warming on stream insects was predicted to be minimal prior to the 2060s; however, by the 2080s, species extirpation of up to 20% in the highland areas and 2% in the lowland areas were predicted. The projected responses of stream insects under global warming indicated that species occupying specific habitats could undergo major reductions in habitat. Nevertheless, habitat of 33% of EOPT (including two-thirds of Odonata and one-third of Ephemeroptera, Plecoptera, and Trichoptera) was predicted to increase due to global warming. The community compositions predicted by generalized additive models varied over this century, and a large difference in community structure in the highland areas was predicted between the 2000s and the 2080s. However, stream insect communities, especially Odonata, Plecoptera, and Trichoptera, were predicted to become more homogenous under global warming. © 2013 Society for Conservation Biology.

Shifting corporate geographies in global cities of the South: Mexico City and Johannesburg as case studie

2013-09-01

Full Text Available Global city research links the expansion of advanced producer services in major cities to the internationalisation of real estate markets as well as to the spread of (mainly high-rise office complexes. This research, however, has based its findings mainly on cases of the Global North. This paper examines, based on Grant and Nijman’s (2002 suggestion that the “internal spatial organisation of gateway cities in the less-developed world” reflects “the city’s role in the global political economy”, which patterns occur in two metropoles of the Global South. In addition to this, the analysis focuses especially on the driving forces behind the changes in corporate geographies. The analysis is placed in Mexico City and Johannesburg and based on real estate market data (offices as well as background documents on urban development. The outcome shows that in these cities, local transformation processes of the real estate market and office space location are indeed considerably shaped by global market dynamics. However, the findings also indicate that there is no clear scale dependence of the territorial form. In order to comprehensively understand the changes in the corporate geographies therefore, it is necessary to direct more attention to local and national dynamics. The restructuring of the built environment in both cities can only be grasped fully by considering the particular role of local and national governments. This additional entry point to an understanding of shifting corporate geographies helps to put recent dynamics of global capitalism and politics of urban neoliberalism in perspective.

The second wave of violence scholarship: South African synergies with a global research agenda.

Violence is a serious public health and human rights challenge with global psychosocial impacts across the human lifespan. As a middle-income country (MIC), South Africa experiences high levels of interpersonal, self-directed and collective violence, taking physical, sexual and/or psychological forms. Careful epidemiological research has consistently shown that complex causal pathways bind the social fabric of structural inequality, socio-cultural tolerance of violence, militarized masculinity, disrupted community and family life, and erosion of social capital, to individual-level biological, developmental and personality-related risk factors to produce this polymorphic profile of violence in the country. Engaging with a concern that violence studies may have reached something of a theoretical impasse, 'second wave' violence scholars have argued that the future of violence research may not lie primarily in merely amassing more data on risk but rather in better theorizing the mechanisms that translate risk into enactment, and that mobilize individual and collective aspects of subjectivity within these enactments. With reference to several illustrative forms of violence in South Africa, in this article we suggest revisiting two conceptual orientations to violence, arguing that this may be useful in developing thinking in line with this new global agenda. Firstly, the definition of our object of enquiry requires revisiting to fully capture its complexity. Secondly, we advocate for the utility of specific incident analyses/case studies of violent encounters to explore the mechanisms of translation and mobilization of multiple interactive factors in enactments of violence. We argue that addressing some of the moral and methodological challenges highlighted in revisiting these orientations requires integrating critical social science theory with insights derived from epidemiology and, that combining these approaches may take us further in understanding and addressing the

The adoption rate of electronic health record (EHR) systems in South Korea has continuously increased. However, in contrast to the situation in the United States (US), where there has been a national effort to improve and standardize EHR interoperability, no consensus has been established in South Korea. The goal of this study was to determine the current status of EHR adoption in South Korean hospitals compared to that in the US. All general and tertiary teaching hospitals in South Korea were surveyed regarding their EHR status in 2015 with the same questionnaire as used previously. The survey form estimated the level of adoption of EHR systems according to 24 core functions in four categories (clinical documentation, result view, computerized provider order entry, and decision supports). The adoption level was classified into comprehensive and basic EHR systems according to their functionalities. EHRs and computerized physician order entry systems were used in 58.1% and 86.0% of South Korean hospitals, respectively. Decision support systems and problem list documentation were the functions most frequently missing from comprehensive and basic EHR systems. The main barriers cited to adoption of EHR systems were the cost of purchasing (48%) and the ongoing cost of maintenance (11%). The EHR adoption rate in Korean hospitals (37.2%) was higher than that in US hospitals in 2010 (15.1%), but this trend was reversed in 2015 (58.1% vs. 75.2%). The evidence suggests that these trends were influenced by the level of financial and political support provided to US hospitals after the HITECH Act was passed in 2009. The EHR adoption rate in Korea has increased, albeit more slowly than in the US. It is logical to suggest that increased funding and support tied to the HITECH Act in the US partly explains the difference in the adoption rates of EHRs in both countries.

2017-08-17

How is global-North predominance in the making of organized knowledge affected by the rise of new domains of research? This question is examined empirically in three interdisciplinary areas - climate change, HIV-AIDS, and gender studies - through interviews with 70 researchers in Southern-tier countries Brazil, South Africa and Australia. The study found that the centrality of the North was reinstituted as these domains came into existence, through resource inequalities, workforce mechanisms, and intellectual framing. Yet there are tensions in the global economy of knowledge, around workforce formation, hierarchies of disciplines, neoliberal management strategies, and mismatches with social need. Intellectual workers in the Southern tier have built significant research centres, workforces and some distinctive knowledge projects. These create wider possibilities of change in the global structure of organized knowledge production. © London School of Economics and Political Science 2017.

Electronic Health Records in the Cloud: Improving Primary Health Care Delivery in South Africa.

Science.gov (United States)

Cilliers, Liezel; Wright, Graham

2017-01-01

In South Africa, the recording of health data is done manually in a paper-based file, while attempts to digitize healthcare records have had limited success. In many countries, Electronic Health Records (EHRs) has developed in silos, with little or no integration between different operational systems. Literature has provided evidence that the cloud can be used to 'leapfrog' some of these implementation issues, but the adoption of this technology in the public health care sector has been very limited. This paper aims to identify the major reasons why the cloud has not been used to implement EHRs for the South African public health care system, and to provide recommendations of how to overcome these challenges. From the literature, it is clear that there are technology, environmental and organisational challenges affecting the implementation of EHRs in the cloud. Four recommendations are provided that can be used by the National Department of Health to implement EHRs making use of the cloud.

Woody encroachment over 70 years in South African savannahs: overgrazing, global change or extinction aftershock?

Woody encroachment in 'open' biomes like grasslands and savannahs is occurring globally. Both local and global drivers, including elevated CO2, have been implicated in these increases. The relative importance of different processes is unresolved as there are few multi-site, multi-land-use evaluations of woody plant encroachment. We measured 70 years of woody cover changes over a 1020 km(2) area covering four land uses (commercial ranching, conservation with elephants, conservation without elephants and communal rangelands) across a rainfall gradient in South African savannahs. Different directions of woody cover change would be expected for each different land use, unless a global factor is causing the increases. Woody cover change was measured between 1940 and 2010 using the aerial photo record. Detection of woody cover from each aerial photograph was automated using eCognitions' Object-based image analysis (OBIA). Woody cover doubled in all land uses across the rainfall gradient, except in conservation areas with elephants in low-rainfall savannahs. Woody cover in 2010 in low-rainfall savannahs frequently exceeded the maximum woody cover threshold predicted for African savannahs. The results indicate that a global factor, of which elevated CO2 is the likely candidate, may be driving encroachment. Elephants in low-rainfall savannahs prevent encroachment and localized megafaunal extinction is a probable additional cause of encroachment.This article is part of the themed issue 'Tropical grassy biomes: linking ecology, human use and conservation'. © 2016 The Author(s).

Crop production is likely to change in the future as a result of global changes in CO2 levels in the atmosphere and climate. APSIM, a cropping system model, was used to investigate the potential impact of these changes on the distribution of cropping along an environmental transect in south Australia. The effects of several global change scenarios were studied, including: (1) historical climate and CO2 levels, (2) historic climate with elevated CO2 (700 ppm), (3) warmer climate (+2.4 degrees C) +700 ppm CO2, (4) drier climate (-15% summer, -20% winter rainfall) +2.4 degrees C +700 ppm CO2, (5) wetter climate (+10% summer rainfall) +2.4 degrees C +700 ppm CO2 and (6) most likely climate changes (+1.8 degrees C, -8% annual rainfall) +700 ppm CO2. Based on an analysis of the current cropping boundary, a criterion of 1 t/ha was used to assess potential changes in the boundary under global change. Under most scenarios, the cropping boundary moved northwards with a further 240,000 ha potentially being available for cropping. The exception was the reduced rainfall scenario (4), which resulted in a small retreat of cropping from its current extent. However, the impact of this scenario may only be small (in the order of 10,000-20,000 ha reduction in cropping area). Increases in CO2 levels over the current climate record have resulted in small but significant increases in simulated yields. Model limitations are discussed.

Full Text Available This paper focus upon the changes of global infectious disease governance in 2000s and the transformation of infectious disease control system in South Korea. Traditionally, infectious disease was globally governed by the quarantine regulated by the international conventions. When an infectious disease outbreak occurred in one country, each country prevented transmission of the disease through the standardized quarantine since the installation of international sanitary convention in 1892. Republic of Korea also organized the infectious disease control system with quarantine and disease report procedure after the establishment of government. Additionally, Korea National Health Institute(KNIH was founded as research and training institute for infectious disease. However, traditional international health regulation system faced a serious challenge by the appearance of emerging and re-emerging infectious disease in 1990s. As a result, global infectious disease governance was rapidly changed under the demand to global disease surveillance and response. Moreover, global health security frame became important after 2001 bioterror and 2003 SARS outbreak. Consequently, international health regulation was fully revised in 2005, which included not only infectious disease but also public health emergency. The new international health regime was differently characterized in several aspects; reinforcement of global cooperation and surveillance, enlargement of the role of supranational and international agencies, and reorganization of national capacity. KNIH was reorganized with epidemic control and research since late 1990s. However, in 2004 Korea Center for Disease Control and Prevention(KCDC was established as a disease control institution with combining quarantine and other functions after 2003 SARS outbreak.

Global auroral conductance distribution due to electron and proton precipitation from IMAGE-FUV observations

Directory of Open Access Journals (Sweden)

V. Coumans

2004-04-01

Full Text Available The Far Ultraviolet (FUV imaging system on board the IMAGE satellite provides a global view of the north auroral region in three spectral channels, including the SI12 camera sensitive to Doppler shifted Lyman-α emission. FUV images are used to produce instantaneous maps of electron mean energy and energy fluxes for precipitated protons and electrons. We describe a method to calculate ionospheric Hall and Pedersen conductivities induced by auroral proton and electron ionization based on a model of interaction of auroral particles with the atmosphere. Different assumptions on the energy spectral distribution for electrons and protons are compared. Global maps of ionospheric conductances due to instantaneous observation of precipitating protons are calculated. The contribution of auroral protons in the total conductance induced by both types of auroral particles is also evaluated and the importance of proton precipitation is evaluated. This method is well adapted to analyze the time evolution of ionospheric conductances due to precipitating particles over the auroral region or in particular sectors. Results are illustrated with conductance maps of the north polar region obtained during four periods with different activity levels. It is found that the proton contribution to conductance is relatively higher during quiet periods than during substorms. The proton contribution is higher in the period before the onset and strongly decreases during the expansion phase of substorms. During a substorm which occurred on 28 April 2001, a region of strong proton precipitation is observed with SI12 around 14:00MLT at ~75° MLAT. Calculation of conductances in this sector shows that neglecting the protons contribution would produce a large error. We discuss possible effects of the proton precipitation on electron precipitation in auroral arcs. The increase in the ionospheric conductivity, induced by a former proton precipitation can reduce the potential drop

Theological Libraries and “The Next Christendom:” Connecting North American Theological Education to Uses of the Book in the Global South

Directory of Open Access Journals (Sweden)

John B. Weaver

2008-11-01

Full Text Available Survey of the past thirty years of librarian literature on the documentation of world Christianity indicates a number of trends in theological librarianship, including a relative inattention to the connection between the documentation of world Christianity in ATLA libraries, and the needs of theological researchers in North America. A trilogy of recent books by Philip Jenkins on the globalization of Christianity argues for the significance of the writings of the “global South” to reading habits in the “global North.” Based on the work of Jenkins and other scholars, this paper identifies ten specific connections between North American theological education and the documentation of world Christianity – connections that are rooted in the uses of the book in the global South. These are reasons for increased promotion and support of the documentation of world Christianity among ATLA libraries.

Supply chain integration in the South African conveyancing environment

Directory of Open Access Journals (Sweden)

Anthea P. Amadi-Echendu

2016-05-01

Full Text Available Background: Although conveyancing is a legal term, business management and specifically operations management principles also apply to the processes involved in conveyancing. From a business perspective, each organisation is usually concerned with its own profit margins and processes. In our global market, however, organisations now realise that they can no longer compete successfully on the basis of their internal operational efficiencies alone. They are therefore constantly aware of the need to improve not only their internal processes but also their alignment with other supply chain linkages in an effort to optimise the performance of the whole supply chain. Such alignment, in the conveyancing environment, includes government departments that are generally less willing to adopt business principles, which in turn makes optimisation of the whole supply chain more difficult. Objectives: The article describes a supply chain perspective of the conveyancing processes in South Africa and reports some of the factors that influence and delay conveyancing transactions. It explores possibilities of collaborative relationships between different role players in the conveyancing supply chain. It aims to show that a supply chain approach, as opposed to a singular organisational approach, can help to reduce process bottlenecks and delays in order to improve overall process efficiency. Method: The research, on which the findings are based, was exploratory in nature and followed a mixed-methods (quantitative or qualitative approach and included both structured questionnaires and personal interviews. Results: The results of the study revealed that many different types of delays occur at various entities across the whole supply chain involved in property transfers. These delays are presented in a table and diagram. Conclusion: It is recommended that greater adoption of electronic technology across the whole supply chain would improve overall efficiency

Global magnetic anomaly and aurora of Neptune

International Nuclear Information System (INIS)

Cheng, A.F.

1990-01-01

The large offset and tilt of Neptune's dipole magnetic field combine to create a global magnetic anomaly, analogous to but much more important than Earth's South Atlantic Anomaly. Energetic particle precipitation loss within the Neptune anomaly creates atmospheric drift shadows within which particle fluxes are greatly reduced. The energetic particle dropout observed by Voyager near closest approach occurred near the predicted times when Voyager passed within the atmospheric drift shadow. Extremely soft, structured bursts of ions and electrons within the drift shadow may result from plasma wave-induced pitch angle scattering of trapped particles confined near the magnetic equator. The dropout does not necessarily imply that Voyager passed through an Earth-like discrete auroral zone, as earlier reported. The ion and electron fluxes observed within the dropout period correspond to particles that must precipitate to Neptune's atmosphere within the anomaly region. This anomaly precipitation can account for a major portion of the ultraviolet emissions previously identified as Neptune aurora

2018-01-01

MomConnect is a national initiative coordinated by the South African National Department of Health that sends text-based mobile phone messages free of charge to pregnant women who voluntarily register at any public healthcare facility in South Africa. We describe the system design and architecture of the MomConnect technical platform, planned as a nationally scalable and extensible initiative. It uses a health information exchange that can connect any standards-compliant electronic front-end application to any standards-compliant electronic back-end database. The implementation of the MomConnect technical platform, in turn, is a national reference application for electronic interoperability in line with the South African National Health Normative Standards Framework. The use of open content and messaging standards enables the architecture to include any application adhering to the selected standards. Its national implementation at scale demonstrates both the use of this technology and a key objective of global health information systems, which is to achieve implementation scale. The system's limited clinical information, initially, allowed the architecture to focus on the base standards and profiles for interoperability in a resource-constrained environment with limited connectivity and infrastructural capacity. Maintenance of the system requires mobilisation of national resources. Future work aims to use the standard interfaces to include data from additional applications as well as to extend and interface the framework with other public health information systems in South Africa. The development of this platform has also shown the benefits of interoperability at both an organisational and technical level in South Africa.

Global concern for increased energy demand, increased cost of natural gas and petroleum, energy security and environmental degradation are leading to heightened interest in using nuclear energy and hydrogen to leverage existing hydrocarbon reserves. The wasteful use of hydrocarbons can be minimised by using nuclear as a source of energy and water as a source of hydrogen. Virtually all hydrogen today is produced from fossil fuels, which give rise to CO{sub 2} emissions. Hydrogen can be cleanly produced from water (without CO{sub 2} pollution) by using nuclear energy to generate the required electricity and/or process heat to split the water molecule. Once the clean hydrogen has been produced, it can be used as feedstock to fuel cell technologies, or in the nearer term as feedstock to a coal-to-liquids process to produce cleaner synthetic liquid fuels. Clean liquid fuels from coal - using hydrogen generated from nuclear energy - is an intermediate step for using hydrogen to reduce pollution in the transport sector; simultaneously addressing energy security concerns. Several promising water-splitting technologies have been identified. Thermo-chemical water-splitting and high-temperature steam electrolysis technologies require process temperatures in the range of 850 deg. C and higher for the efficient production of hydrogen. The pebble bed modular reactor (PBMR), under development in South Africa, is ideally suited to generate both high-temperature process heat and electricity for the production of hydrogen. This paper will discuss South Africa's opportunity to maximise the use of its nuclear technology and national resources in a global hydrogen economy.

First Extraction of Transversity from a Global Analysis of Electron-Proton and Proton-Proton Data

Science.gov (United States)

Radici, Marco; Bacchetta, Alessandro

2018-05-01

We present the first extraction of the transversity distribution in the framework of collinear factorization based on the global analysis of pion-pair production in deep-inelastic scattering and in proton-proton collisions with a transversely polarized proton. The extraction relies on the knowledge of dihadron fragmentation functions, which are taken from the analysis of electron-positron annihilation data. For the first time, the transversity is extracted from a global analysis similar to what is usually done for the spin-averaged and helicity distributions. The knowledge of transversity is important for, among other things, detecting possible signals of new physics in high-precision low-energy experiments.

Infectious bronchitis virus (IBV) is a coronavirus of chickens that causes great economic losses to the global poultry industry. The present study focuses on South American IBVs and their genetic relationships with global strains. We obtained full-length sequences of the S1 coding region and N gene of IBV field isolates from Uruguay and Argentina, and performed Phylodynamic analysis to characterize the strains and estimate the time of the most recent common ancestor. We identified two major South American genotypes, which were here denoted South America I (SAI) and Asia/South America II (A/SAII). The SAI genotype is an exclusive South American lineage that emerged in the 1960s. The A/SAII genotype may have emerged in Asia in approximately 1995 before being introduced into South America. Both SAI and A/SAII genotype strains clearly differ from the Massachusetts strains that are included in the vaccine formulations being used in most South American countries. © 2015 The Authors.

2012-04-01

The objective of the present study was to determine the exact location of the latitudinal limit of western South Atlantic mangroves, and to describe how these forests develop at this limit; as well as to analyze the potential responses of these communities to global warming. The study was carried out along the coast of Santa Catarina, Brazil. Specific studies on mangrove structure were carried out in the Santo Antônio Lagoon (28°28'34″S; 48°51'40″W). The coastline of Santa Catarina was surveyed for the occurrence of mangrove species. In the mangrove located at the southernmost distributional limit, the forest structure was characterized. Mean height and diameter, trunks density and basal area were calculated. Climatic and oceanographic factors controlling the occurrence and development of the mangrove forests at their latitudinal limit were analyzed, as well as the possible changes of this limit based on global warming scenarios. The results confirmed that the Santo Antônio Lagoon is the southern limit of the western South Atlantic mangroves. At this limit, the mangrove forests show a low degree of development, defined by low mean diameter and height, and high trunks density and trunks/tree ratio. The observed structural pattern and the local alternation of these forests with salt marsh species are typical of mangrove forests at their latitudinal limits. The absence of mangroves south of Laguna and forest structure at the latitudinal limit are controlled by rigorous climate and oceanographic characteristics. In response to the planetary warming process, we expect that mangroves will expand southward, as a consequence of an increase in air and ocean surface temperatures, a reduction in the incidence of frosts, an increased influence of the Brazil Current and a decreased influence of the Falkland Current, and the availability of sheltered estuarine systems for the establishment of new mangroves.

Cretaceous paleogeography and depositional cycles of western South America

Science.gov (United States)

Macellari, C. E.

The western margin of South America was encroached upon by a series of marine advances that increased in extent from the Early Cretaceous to a maximum in the early Late Cretaceous for northern South America (Venezuela to Peru). In southern South America, however, the area covered by the marine advances decreased from a maximum in the Early Cretaceous to a minimum during mid-Cretaceous time, followed by a widespread advance at the end of the period. A series of unconformity-bounded depositional cycles was recognized in these sequences: five cycles in northern South America, and six (but not exactly equivalent) cycles in the Cretaceous back-arc basins of southern South America (Neuquén and Austral, or Magallanes, Basins). Both widespread anoxic facies and maximum flooding of the continent in northern South America coincide in general terms with recognized global trends, but this is not the case in southern South America. Here, anoxic facies are restricted to the Lower Cretaceous and seem to be controlled by local aspects of the basin evolution and configuration. The contrasts observed between northern and southern South America can be explained by differences in tectonic setting and evolution. To the north, sediments were deposited around the tectonically stable Guayana-Brazilian Massifs, and thus registered global "signals" such as anoxic events and major eustatic changes. The southern portion of the continent, on the contrary, developed in an active tectonic setting. Here, the mid-Cretaceous Peruvian Orogeny overprinted, to a large extent, world-wide trends and only the earliest and latest Cretaceous conform to global depositional patterns.

Exploring the impact of the 2008 global food crisis on food security among vulnerable households in rural South Africa.

Recurring food crises endanger the livelihoods of millions of households in developing countries around the globe. Owing to the importance of this issue, we explore recent changes in food security between the years 2004 and 2010 in a rural district in Northeastern South Africa. Our study window spans the time of the 2008 global food crises and allows the investigation of its impacts on rural South African populations. Grounded in the sustainable livelihood framework, we examine differences in food security trajectories among vulnerable sub populations. A unique panel data set of 8,147 households, provided by the Agincourt Health and Demographic Surveillance System (Agincourt HDSS), allows us to employ a longitudinal multilevel modeling approach to estimate adjusted growth curves for the differential change in food security across time. We observe an overall improvement in food security that leveled off after 2008, most likely resulting from the global food crisis. In addition, we discover significant differences in food security trajectories for various sub populations. For example, female-headed households and those living in areas with better access to natural resources differentially improved their food security situation, compared to male-headed households and those households with lower levels of natural resource access. However, former Mozambican refugees witnessed a decline in food security. Therefore, poverty alleviation programs for the Agincourt region should work to improve the food security of vulnerable households, such as former Mozambican refugees.

South-South exchanges enhance resource management and biodiversity conservation at various scales

Directory of Open Access Journals (Sweden)

William D Heyman

2011-01-01

Full Text Available International conservation organisations have invested considerable resources in fostering biodiversity conservation programs in the humid tropics, the most biologically diverse areas on earth. Recent approaches to conservation have centered on integrated conservation and development projects and participatory resource management programs, co-managed between governments and local communities. But these programs have had only mixed success and often suffer from insufficient quantity or quality of participation by local communities. We pose that participatory resource management is more likely to succeed when community members, 1 gain a global perspective on how their social, economic and environmental conditions compare with peer communities in other similar areas of the world, and thus better understand issues of relative scarcity and the benefits of sustainable resource management, and 2 engage as decision-makers at every stage of the conservation process up to reflective program evaluation. This paper examines the role of South-South exchanges as a tool to achieve these intermediate goals that ultimately foster more effective and participatory conservation and support sustainable local livelihoods. The data are extracted from the initiatives of the authors in two different environments- marine and coastal communities in Central America and the Caribbean, and lowland rainforest communities in the western Amazon of South America. We conclude that the exchanges are effective ways to build stakeholder comprehension about, and meaningful engagement in, resource management. South-South exchanges may also help build multi-local coalitions from various remote areas that together support biodiversity conservation at regional and global scales.

Disaster resilience assessment and the global agenda: A journey from India to South America

Fanchiotti, Margherita; Torres, Jair; Burton, Christopher; Makarigakis, Alexandros

Governments and stakeholders worldwide are placing great emphasis on fostering the resilience of communities to natural hazards and disasters. This is partially because communities that can increase their resilience are in a better position to withstand the adverse effects of damaging hazard events when they occur. With disaster risk reduction having emerged as a global challenge, the Sendai Framework for Disaster Risk Reduction 2015-2030 has recognised the need to invest in enhancing disaster resilience as a priority on the international agenda. In order to successfully build community resilience to natural hazards, it then becomes essential to first understand, identify and assess all sets of conditions that contribute to resilience. The ability to measure resilience is increasingly being identified as a key step towards disaster risk reduction as a result. Relatively few studies, however, have been conducted to develop guidelines for measuring the concept, and more research is needed to develop effective tools for assessment of resilience in developing countries. This is because various environmental, built-environment, and social factors will operate and interact differentially across disaster and development contexts. This paper presents preliminary findings from two large projects in which the authors have been involved, namely the 'Enhancing Natural HAzards resilience iN South America' (ENHANS) and 'Deltas, Vulnerability & Climate Change: Migration & Adaptation' (DECCMA) projects. In collaboration with the Global Earthquake Model (GEM), the Understanding and Managing Extremes (UME) School of the Institute for Advanced Study (IUSS) of Pavia and the University of Southampton, UNESCO is working on the development of methods for disaster resilience measurement in developing nations. The studies build on the available literature to provide an ad-hoc conceptual framework for the quantification of community resilience in each study site by means of a bottom

The Interdecadal Variability of Summer Precipitation over the South of China and its Response to Asian Monsoon at the Turning Points of Global Warming

Under the background of global warming, decadal variability of the summer precipitation in the South of China and the Asian monsoon experienced mutations at around the end of 1970s, the beginning of 1990s and 21st century. We examined the external and internal forcings which may cause the mutations and diagnosed the mechanism. Human emission of CO2 has always been the fatal reason for global warming, and it is also the primary reason for the precipitation increasing over Yangtze-Huai river basin at the end of the 1970s. The Yangtze-Huai river basin and South China demonstrated more summer rainfall after 1993. This can be explained by the weakening of the Asian summer monsoon caused by the positive anomaly of summer SST over northwest Pacific Ocean and Indian Ocean. A significant trend in the enhancement of sensible heat over the TP has exerted some considerable influence on the reinforce of the EASM, accompanied by the northward migration of the summer precipitation belt shifting northward at the beginning of 21st century.

Local Reasons to Give Globally: Identity Extension and Global Cooperation.

Science.gov (United States)

Buchan, Nancy R; Jeong, Sophia Soyoung; Ward, A K

2017-11-14

Recent political events across the world suggest a retrenchment from globalization and a possible increase in parochialism. This inward-looking threat from parochialism occurs just as the global community faces growing challenges that require trans-national cooperation. In this research, we question if strong identification with an in-group necessarily leads to parochialism and ultimately is detrimental to global cooperation. Building on research on global social identification, we explore whether strong local identification can expand in inclusiveness to global identification, and among whom this is likely to happen. The results of our global public goods study - conducted in South Korea and the United States - show that high levels of social identification with a local group can extend to the global collective, particularly for individuals who are also high in concern-for-others. Furthermore, this identification translates into behavior that benefits the global, anonymous group at a cost to oneself. These results shed light on how to avoid the trap of parochialism and instead engender cooperative behavior with the broader global community.

Grey mullet (Mugilidae) as possible indicators of global warming in South African estuaries and coastal waters.

Science.gov (United States)

James, Nicola C; Whitfield, Alan K; Harrison, Trevor D

2016-12-01

The grey mullet usually occur in large numbers and biomass in the estuaries of all three South African biogeographic regions, thus making it an ideal family to use in terms of possibly acting as an environmental indicator of global warming. In this analysis the relative estuarine abundance of the dominant three groups of mugilids, namely tropical, warm-water and cool-water endemics, were related to sea surface coastal temperatures. The study suggests a strong link between temperature and the distribution and abundance of the three mullet groups within estuaries and indicates the potential of this family to act as an indicator for future climate change within these systems and adjacent coastal waters.

Conservation concern regarding the overharvest of global shark populations for meat and fin consumption largely surrounds documented deleterious ecosystem effects, but may be further supported by improved knowledge of possibly high levels in their edible tissues (particularly meat) of the neurotoxin, methylmercury (CH_3Hg). For many regions, however, little data exist on shark tissue Hg concentrations, and reasons for Hg variation within and among species or across regions are poorly understood. We quantified total Hg (THg) in 17 shark species (total n = 283) from the east coast of South Africa, a top Hg emitter globally. Concentrations varied from means of around 0.1 mg kg"−"1 dry weight (dw) THg in hardnose smoothhound (Mustelus mosis) and whale (Rhincodon typus) sharks to means of over 10 mg kg"−"1 dw in shortfin mako (Isurus oxyrinchus), scalloped hammerhead (Sphyrna lewini), white (Carcharodon carcharias) and ragged-tooth (Carcharias taurus) sharks. These sharks had higher THg levels than conspecifics sampled from coastal waters of the North Atlantic and North, mid-, and South Pacific, and although sampling year and shark size may play a confounding role, this result suggests the potential importance of elevated local emissions. Values of THg showed strong, species-specific correlations with length, and nearly half the remaining variation was explained by trophic position (using nitrogen stable isotopes, δ"1"5N), whereas measures of foraging habitat (using carbon stable isotopes, δ"1"3C) were not significant. Mercury concentrations were above the regulatory guidelines for fish health effects and safe human consumption for 88% and 70% of species, respectively, suggesting on-going cause for concern for shark health, and human consumers of shark meat. - Highlights: • Hg concentrations in 17 shark species from South Africa's east coast were measured. • Higher values relative to other regions suggested the importance of local emissions. • Length and

The IAU established its Office of Astronomy for Development in 2011 in Cape Town, South Africa, in partnership with the South African National Research Foundation, and hosted at the South African Astronomical Observatory. The primary purpose of the office has been to implement the IAU's decadal strategic plan which aims to use astronomy to stimulate education and development globally. Since its inception there have been nine regional offices established, including one in the Latin American region which focuses on Andean countries. Following a very positive external review in 2015, as well as a supportive resolution by the 2015 IAU General Assembly to continue the work of the office, the OAD is now in a position to move beyond the setting up of structures to a more intensive effort aimed at measuring and delivering programmes with broader global impact.

Artisanal Fisheries Research: A Need for Globalization?

Oliveira Júnior, José Gilmar C; Silva, Luana P S; Malhado, Ana C M; Batista, Vandick S; Fabré, Nidia N; Ladle, Richard J

2016-01-01

Given limited funds for research and widespread degradation of ecosystems, environmental scientists should geographically target their studies where they will be most effective. However, in academic areas such as conservation and natural resource management there is often a mismatch between the geographic foci of research effort/funding and research needs. The former frequently being focused in the developed world while the latter is greater in the biodiverse countries of the Global South. Here, we adopt a bibliometric approach to test this hypothesis using research on artisanal fisheries. Such fisheries occur throughout the world, but are especially prominent in developing countries where they are important for supporting local livelihoods, food security and poverty alleviation. Moreover, most artisanal fisheries in the Global South are unregulated and unmonitored and are in urgent need of science-based management to ensure future sustainability. Our results indicate that, as predicted, global research networks and centres of knowledge production are predominantly located in developed countries, indicating a global mismatch between research needs and capacity.

Global warming threatens agricultural productivity in Africa and South Asia

Science.gov (United States)

Sultan, Benjamin

2012-12-01

The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC; Christensen et al 2007) has, with greater confidence than previous reports, warned the international community that the increase in anthropogenic greenhouse gases emissions will result in global climate change. One of the most direct and threatening impacts it may have on human societies is the potential consequences on global crop production. Indeed agriculture is considered as the most weather-dependent of all human activities (Hansen 2002) since climate is a primary determinant for agricultural productivity. The potential impact of climate change on crop productivity is an additional strain on the global food system which is already facing the difficult challenge of increasing food production to feed a projected 9 billion people by 2050 with changing consumption patterns and growing scarcity of water and land (Beddington 2010). In some regions such as Sub-Saharan Africa or South Asia that are already food insecure and where most of the population increase and economic development will take place, climate change could be the additional stress that pushes systems over the edge. A striking example, if needed, is the work from Collomb (1999) which estimates that by 2050 food needs will more than quintuple in Africa and more than double in Asia. Better knowledge of climate change impacts on crop productivity in those vulnerable regions is crucial to inform policies and to support adaptation strategies that may counteract the adverse effects. Although there is a growing literature on the impact of climate change on crop productivity in tropical regions, it is difficult to provide a consistent assessment of future yield changes because of large uncertainties in regional climate change projections, in the response of crops to environmental change (rainfall, temperature, CO2 concentration), in the coupling between climate models and crop productivity functions, and in the adaptation of

Cooperation for Development, Brazilian Regional Leadership and Global Protagonism

Directory of Open Access Journals (Sweden)

Leticia Pinheiro

2014-08-01

Full Text Available This article aims to analyze Brazil’s policy towards South America during Luiz Inácio "Lula" da Silva’s government by discussing what kind of leadership the country was able to perform in the region during this time. The authors examine the role played by the policy of International Cooperation for Development on such regional leadership. The central argument is that although Brazil has performed the role of a regional leader, there is a need for distinguishing leadership for regional matters – inwards regional leadership – from leadership for global issues – outwards regional leadership. We argue that inwards regional leadership was in fact successfully performed by Brazil in South America, mainly due to its role as a Development Leader. On the other hand, we also verified that such leadership for regional matters did not always allow Brazil to act on behalf of the entire region on the global arena. Nevertheless, we argue that Brazilian diplomacy left behind the belief that, in order to have global protagonism, the country should use South America as a regional launching platform. Instead, Brazil has been making use of global coalitions such as IBSA and BRICS to boost its global role.

The assessment covers the Philippines in Southeast Asia, and the Republic of Korea (South Korea), Taiwan (Province of China), and Japan in East Asia. The Philippines host world class porphyry copper deposits, such as the Tampakan and Atlas deposits. No porphyry copper deposits have been discovered in the Republic of Korea (South Korea), Taiwan (Province of China), or Japan.

Where theory and practice of global health intersect: the developmental history of a Canadian global health initiative.

Science.gov (United States)

Daibes, Ibrahim; Sridharan, Sanjeev

2014-01-01

This paper examines the scope of practice of global health, drawing on the practical experience of a global health initiative of the Government of Canada--the Teasdale-Corti Global Health Research Partnership Program. A number of challenges in the practical application of theoretical definitions and understandings of global health are addressed. These challenges are grouped under five areas that form essential characteristics of global health: equity and egalitarian North-South partnerships, interdisciplinary scope, focus on upstream determinants of health, global conceptualization, and global health as an area of both research and practice. Information in this paper is based on the results of an external evaluation of the program, which involved analysis of project proposals and technical reports, surveys with grantees and interviews with grantees and program designers, as well as case studies of three projects and a review of relevant literature. The philosophy and recent definitions of global health represent a significant and important departure from the international health paradigm. However, the practical applicability of this maturing area of research and practice still faces significant systemic and structural impediments that, if not acknowledged and addressed, will continue to undermine the development of global health as an effective means to addressing health inequities globally and to better understanding, and acting upon, upstream determinants of health toward health for all. While it strives to redress global inequities, global health continues to be a construct that is promoted, studied, and dictated mostly by Northern institutions and scholars. Until practical mechanisms are put in place for truly egalitarian partnerships between North and South for both the study and practice of global health, the emerging philosophy of global health cannot be effectively put into practice.

Anthropometry of south Indian industrial workmen.

Science.gov (United States)

Fernandez, J E; Uppugonduri, K G

1992-11-01

This paper presents the results of an anthropometric survey conducted on South Indian male workers in the electronic industry. The data were collected as part of a project to modify work stations that utilized equipment from other countries. A set of 27 body dimensions were taken from a sample of 128 workmen (aged 18-35 years). The anthropometric measurements are compared with those of Indian men from Central, Western, and Northern parts of India and with those of the American, German, and Japanese men. The results indicate that in general the South Indian man is smaller than Central, Western, and Northern Indian men, as well as smaller than men in America, Germany, Japan, and Africa. This difference needs to be allowed for when considering buying and subsequently using imported equipment for the electronics industry in South India.

Global model analysis of negative ion generation in low-pressure inductively coupled hydrogen plasmas with bi-Maxwellian electron energy distributions

Huh, Sung-Ryul; Kim, Nam-Kyun; Jung, Bong-Ki; Chung, Kyoung-Jae; Hwang, Yong-Seok; Kim, Gon-Ho

2015-01-01

A global model was developed to investigate the densities of negative ions and the other species in a low-pressure inductively coupled hydrogen plasma with a bi-Maxwellian electron energy distribution. Compared to a Maxwellian plasma, bi-Maxwellian plasmas have higher populations of low-energy electrons and highly vibrationally excited hydrogen molecules that are generated efficiently by high-energy electrons. This leads to a higher reaction rate of the dissociative electron attachment responsible for negative ion production. The model indicated that the bi-Maxwellian electron energy distribution at low pressures is favorable for the creation of negative ions. In addition, the electron temperature, electron density, and negative ion density calculated using the model were compared with the experimental data. In the low-pressure regime, the model results of the bi-Maxwellian electron energy distributions agreed well quantitatively with the experimental measurements, unlike those of the assumed Maxwellian electron energy distributions that had discrepancies

North and south: Regional footprints on the transition pathway towards a low carbon, global economy

International Nuclear Information System (INIS)

Cranston, G.R.; Hammond, G.P.

2010-01-01

Environmental or 'ecological' footprints are indicators of resource consumption and waste absorption transformed on the basis of biologically productive land area required per capita with prevailing technology. They represent a partial measure of the extent to which the planet, its regions, or nations are moving along a sustainable development pathway. Such footprints vary between countries at different stages of economic development and varying geographic characteristics. A correlation equation for national environmental footprints is used, alongside international projections of population growth and gross regional income, to estimate the relative contributions of the peoples of the industrialised North and populous South that would be needed in order to secure climate-stabilising carbon reductions out to about 2100. The four so-called 'marker scenarios' produced by the Intergovernmental Panel on Climate Change are used to estimate the degree of energy efficiency improvement and carbon mitigation that is feasible. The present footprint projections suggest that a reduction in the consumption of biophysical assets across both the developing and industrialised world is indeed possible. However, the developing world's footprint is shown to overshoot that of the industrialised countries by around 2010-2015. It then levels out and starts to fall, on the most optimistic scenario, by about 2050. In order to achieve global sustainability in the 21st Century a serious commitment to environmental protection is required in both the industrialised North and the 'majority South'. That implies balancing population growth, economic well-being, and environmental impacts in the interests of all the people and wildlife on 'Spaceship Earth'.

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

Science.gov (United States)

Gilbert, Tal; Gilbert, Leah

2004-03-01

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

How Global is Global Civil Society?

Directory of Open Access Journals (Sweden)

Neera Chandhoke

2015-08-01

Full Text Available In recent times the concept of global civil society has made its appearance on national and international intellectual, as well as political agendas, in a major way. It is of some interest that two other concepts, both of which call for transcendence of national boundaries in precisely the same way as global civil society does, have also made their appearance on the scene of intellectual debates at roughly the same time: the concept of cosmopolitanism and that of transnational justice. All three concepts have dramatically expanded the notion of commitment to one’s fellow beings beyond the nation state. And all three concepts have extended critiques of policies that violate the dignity of human beings from national governments to the practices of inter-national institutions such as the World Bank, the International Monetary Fund, and the World Trade Forum. In sum the inter-related concepts of global civil society, cosmopolitanism, and transnational justice have greatly enlarged the traditional domain of political theory. And yet for any political theorist who is acutely conscious of the phenomenon of power, these concepts are not unproblematic. For the practices of global civil society may just reinforce the intellectual and the moral power of the West over the postcolonial world. This is particularly true of say global human rights organizations. This paper will attempt to raise some questions of the concept and the practices of global civil society from the perspective of the countries of the South.

Biohydrogen production as a potential energy fuel in South Africa

Directory of Open Access Journals (Sweden)

P.T. Sekoai

2015-06-01

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

At least half of South Africa's gold production is presently dependent on CFC11 an CFC12 as refrigerants in water chilling machines used in cooling the underground workings. The South African Government will ratify the revised Montreal Protocol on substances that deplete the ozone layer which will mean CFCs will have to be phased out probably by 1997. HFC134 or HFC22 are possible replacements for CFC but present costs of converting machines are high. The article goes on to discuss the contribution of CFCs and CO{sub 2} to global warming and model simulations and predictions of climate change. Likely effects of growing concern about global warming on the coal mining industry are the possible limitations on the use of coal and the increased need for clean coal technology. 12 refs., 5 figs., 3 tabs.

Storm-time total electron content and its response to penetration electric fields over South America

Directory of Open Access Journals (Sweden)

P. M. de Siqueira

2011-10-01

Full Text Available In this work the response of the ionosphere due to the severe magnetic storm of 7–10 November 2004 is investigated by analyzing GPS Total Electron Content (TEC maps constructed for the South America sector. In order to verify the disturbed zonal electric fields in South America during the superstorm, ionospheric vertical drift data obtained from modeling results are used in the analysis. The vertical drifts were inferred from ΔH magnetometer data (Jicamarca-Piura following the methodology presented by Anderson et al. (2004. Also used were vertical drifts measured by the Jicamarca ISR. Data from a digisonde located at São Luís, Brazil (2.33° S, 44.2° W, dip latitude 0.25° are presented to complement the Jicamarca equatorial data. Penetration electric fields were observed by the comparison between the equatorial vertical drifts and the Interplanetary Electric Field (IEF. The TEC maps obtained from GPS data reflect the ionospheric response over the South America low-latitude and equatorial region. They reveal unexpected plasma distributions and TEC levels during the main phase of the superstorm on 7 November, which is coincident with the local post-sunset hours. At this time an increase in the pre-reversal enhancement was expected to develop the Equatorial Ionization Anomaly (EIA but we observed the absence of EIA. The results also reveal well known characteristics of the plasma distributions on 8, 9, and 10 November. The emphasized features are the expansion and intensification of EIA due to prompt penetration electric fields on 9 November and the inhibition of EIA during post-sunset hours on 7, 8, and 10 November. One important result is that the TEC maps provided a bi-dimensional view of the ionospheric changes offering a spatial description of the electrodynamics involved, which is an advantage over TEC measured by isolated GPS receivers.

Our results indicate that, as predicted, global research networks and centres of knowledge production are predominantly located in developed countries, indicating a global mismatch between research needs and capacity.

Decomposing global crop yield variability

Science.gov (United States)

Ben-Ari, Tamara; Makowski, David

2014-11-01

Recent food crises have highlighted the need to better understand the between-year variability of agricultural production. Although increasing future production seems necessary, the globalization of commodity markets suggests that the food system would also benefit from enhanced supplies stability through a reduction in the year-to-year variability. Here, we develop an analytical expression decomposing global crop yield interannual variability into three informative components that quantify how evenly are croplands distributed in the world, the proportion of cultivated areas allocated to regions of above or below average variability and the covariation between yields in distinct world regions. This decomposition is used to identify drivers of interannual yield variations for four major crops (i.e., maize, rice, soybean and wheat) over the period 1961-2012. We show that maize production is fairly spread but marked by one prominent region with high levels of crop yield interannual variability (which encompasses the North American corn belt in the USA, and Canada). In contrast, global rice yields have a small variability because, although spatially concentrated, much of the production is located in regions of below-average variability (i.e., South, Eastern and South Eastern Asia). Because of these contrasted land use allocations, an even cultivated land distribution across regions would reduce global maize yield variance, but increase the variance of global yield rice. Intermediate results are obtained for soybean and wheat for which croplands are mainly located in regions with close-to-average variability. At the scale of large world regions, we find that covariances of regional yields have a negligible contribution to global yield variance. The proposed decomposition could be applied at any spatial and time scales, including the yearly time step. By addressing global crop production stability (or lack thereof) our results contribute to the understanding of a key

Ionospheric tomography over South Africa: Comparison of MIDAS and ionosondes measurements

Giday, Nigussie M.; Katamzi, Zama T.; McKinnell, Lee-Anne

2016-01-01

This paper aims to show the results of an ionospheric tomography algorithm called Multi-Instrument Data Analysis System (MIDAS) over the South African region. Recorded data from a network of 49-53 Global Positioning System (GPS) receivers over the South African region was used as input for the inversion. The inversion was made for April, July, October and December representing the four distinct seasons (Autumn, Winter, Spring and Summer respectively) of the year 2012. MIDAS reconstructions were validated by comparing maximum electron density of the F2 layer (NmF2) and peak height (hmF2) values predicted by MIDAS to those derived from three South African ionosonde measurements. The diurnal and seasonal trends of the MIDAS NmF2 values were in good agreement with the respective NmF2 values derived from the ionosondes. In addition, good agreement was found between the two measurements with minimum and maximum coefficients of determination (r2) between 0.84 and 0.96 in all the stations and validation days. The seasonal trend of the NmF2 values over the South Africa region has been reproduced using this inversion which was in good agreement with the ionosonde measurements. Moreover, a comparison of the International Reference Ionosphere (IRI-2012) model NmF2 values with the respective ionosonde derived NmF2 values showed to have higher deviation than a similar comparison between the MIDAS reconstruction and the ionosonde measurements. However, the monthly averaged hmF2 values derived from IRI 2012 model showed better agreement than the respective MIDAS reconstructed hmF2 values compared with the ionosonde derived hmF2 values.The performance of the MIDAS reconstruction was observed to deteriorate with increased geomagnetic conditions. MIDAS reconstructed electron density were slightly elevated during three storm periods studied (24 April, 15 July and 8 October) which was in good agreement with the ionosonde measurements.

Waste Picker Organizations and Their Contribution to the Circular Economy: Two Case Studies from a Global South Perspective

Directory of Open Access Journals (Sweden)

Jutta Gutberlet

2017-09-01

Full Text Available The discussion on the circular economy (CE has attracted a rising interest within global policy and business as a way of increasing the sustainability of production and consumption. Yet the literature mostly portrays a Global North perspective. There is a diverse spectrum of community-based organizations playing important roles in resource recovery and transformation, particularly, but not only, in Global South countries, providing innovative examples for grassroots involvement in waste management and in the CE. This article proposes to add a Southern lens, situated in the context of waste picker organizations, to the concept of CE. The discursive framework in this article couples ecological economy (EE with social/solidarity economy (SSE, focusing not only on environmental sustainability but also on social, economic, political and cultural dimensions involved in production, consumption and discard. We acknowledge that grassroots movements contribute to policy making and improve urban waste management systems. The paper outlines two empirical studies (Argentina, Brazil that illustrate how waste picker organizations perform selective waste collection services, engage with municipalities and industries, and practice the CE. The research reveals that social and political facets need to be added to the debate about the CE, linking environmental management and policy with community development and recognizing waste pickers as protagonists in the CE. Our findings emphasize a need for a change of persisting inequalities in public policy by recognizing the importance of popular waste management praxis and knowledge, ultimately redefining the CE.

Global health inequalities and the need for solidarity: a view from the Global South.

Although the world has experienced remarkable progress in health care since the last half of the 20th century, global health inequalities still persist. In some poor countries life expectancy is between 37-40 years lower than in rich countries; furthermore, maternal and infant mortality is high and there is lack of access to basic preventive and life-saving medicines, as well a high prevalence of neglected diseases, HIV/AIDS, tuberculosis, and malaria. Moreover, globalization has made the world more connected than before such that health challenges today are no longer limited within national or regional boundaries, making all persons equally vulnerable. Because of this, diseases in the most affluent countries are closely connected with diseases in the poorest countries. In this paper, we argue that, because of global health inequalities, in a situation of equal vulnerability, there is need for global solidarity not only as a means of reducing health inequalities, but also as a way of putting up a united force against global health challenges. We argue for an African approach to solidarity in which the humanity of a person is not determined by his/her being human or rational capacity, but by his/her capacity to live a virtuous life. According to this view of solidarity, because no one is self-sufficient, no individual can survive alone. If we are to collectively flourish in a world where no individual, nation or region has all the health resources or protection needed for survival, we must engage in solidarity where we remain compassionate and available to one another at all times. © 2017 John Wiley & Sons Ltd.

2013-01-01

Conservation of phylogenetic diversity allows maximising evolutionary information preserved within fauna and flora. The "EDGE of Existence" programme is the first institutional conservation initiative that prioritises species based on phylogenetic information. Species are ranked in two ways: one according to their evolutionary distinctiveness (ED) and second, by including IUCN extinction status, their evolutionary distinctiveness and global endangerment (EDGE). Here, we describe the global patterns in the spatial distribution of priority ED and EDGE species, in order to identify conservation areas for mammalian and amphibian communities. In addition, we investigate whether environmental conditions can predict the observed spatial pattern in ED and EDGE globally. Priority zones with high concentrations of ED and EDGE scores were defined using two different methods. The overlap between mammal and amphibian zones was very small, reflecting the different phylo-biogeographic histories. Mammal ED zones were predominantly found on the African continent and the neotropical forests, whereas in amphibians, ED zones were concentrated in North America. Mammal EDGE zones were mainly in South-East Asia, southern Africa and Madagascar; for amphibians they were in central and south America. The spatial pattern of ED and EDGE was poorly described by a suite of environmental variables. Mapping the spatial distribution of ED and EDGE provides an important step towards identifying priority areas for the conservation of mammalian and amphibian phylogenetic diversity in the EDGE of existence programme.

Conservation concern regarding the overharvest of global shark populations for meat and fin consumption largely surrounds documented deleterious ecosystem effects, but may be further supported by improved knowledge of possibly high levels in their edible tissues (particularly meat) of the neurotoxin, methylmercury (CH{sub 3}Hg). For many regions, however, little data exist on shark tissue Hg concentrations, and reasons for Hg variation within and among species or across regions are poorly understood. We quantified total Hg (THg) in 17 shark species (total n = 283) from the east coast of South Africa, a top Hg emitter globally. Concentrations varied from means of around 0.1 mg kg{sup −1} dry weight (dw) THg in hardnose smoothhound (Mustelus mosis) and whale (Rhincodon typus) sharks to means of over 10 mg kg{sup −1} dw in shortfin mako (Isurus oxyrinchus), scalloped hammerhead (Sphyrna lewini), white (Carcharodon carcharias) and ragged-tooth (Carcharias taurus) sharks. These sharks had higher THg levels than conspecifics sampled from coastal waters of the North Atlantic and North, mid-, and South Pacific, and although sampling year and shark size may play a confounding role, this result suggests the potential importance of elevated local emissions. Values of THg showed strong, species-specific correlations with length, and nearly half the remaining variation was explained by trophic position (using nitrogen stable isotopes, δ{sup 15}N), whereas measures of foraging habitat (using carbon stable isotopes, δ{sup 13}C) were not significant. Mercury concentrations were above the regulatory guidelines for fish health effects and safe human consumption for 88% and 70% of species, respectively, suggesting on-going cause for concern for shark health, and human consumers of shark meat. - Highlights: • Hg concentrations in 17 shark species from South Africa's east coast were measured. • Higher values relative to other regions suggested the importance of local

Slightly larger than Portugal, South Korea comprises the lower half on the Korean Peninsula, covering approximately 38 thousand square miles. the Republic of Korea (South Korea) was established in 1948, and until 1962 the country grew slowly. However, through a series of five-year economic plans initiated by South Korean President Park Ching Hee, South Korea has since created an export-oriented economy, which now plays a major role in regional as well as global trade. South Korea has been forced to constantly upgrade its power generation structure in order to sustain the explosive growth it has experienced. Nuclear power has been a major player in this expansion and is expected to play an ever-increasing role. The country presently operates nine nuclear reactors with a total net generating capacity of 7,266 MWe. By the year 2006, the nuclear program is scheduled to grow to 27 reactors, with a net generating capacity exceeding 23 thousand MWe. Once this goal is reached, nuclear-generated power would account for more than 40 percent of the country's total installed electrical capacity

Learning about “wicked” problems in the Global South. Creating a film-based learning environment with “Visual Problem Appraisal”

Directory of Open Access Journals (Sweden)

Loes Witteveen

2012-03-01

Full Text Available The current complexity of sustainable development in the Global South calls for the design of learning strategies that can deal with this complexity. One such innovative learning strategy, called Visual Problem Appraisal (VPA, is highlighted in this article. The strategy is termed visual as it creates a learning environment that is film-based. VPA enhances the analysis of complex issues, and facilitates stakeholder dialogue and action planning. The strategy is used in workshops dealing with problem analysis and policy design, and involves the participants “meeting” stakeholders through filmed narratives. The article demonstrates the value of using film in multi stakeholder learning environments addressing issues concerning sustainable development.

Global proteomic profiling of phosphopeptides using electron transfer dissociation tandem mass spectrometry

DEFF Research Database (Denmark)

Molina, Henrik; Horn, David M; Tang, Ning

2007-01-01

Electron transfer dissociation (ETD) is a recently introduced mass spectrometric technique that provides a more comprehensive coverage of peptide sequences and posttranslational modifications. Here, we evaluated the use of ETD for a global phosphoproteome analysis. In all, we identified a total...... of 1,435 phosphorylation sites from human embryonic kidney 293T cells, of which 1,141 ( approximately 80%) were not previously described. A detailed comparison of ETD and collision-induced dissociation (CID) modes showed that ETD identified 60% more phosphopeptides than CID, with an average of 40% more...... fragment ions that facilitated localization of phosphorylation sites. Although our data indicate that ETD is superior to CID for phosphorylation analysis, the two methods can be effectively combined in alternating ETD and CID modes for a more comprehensive analysis. Combining ETD and CID, from this single...

Brazil, Russia, India, China and South Africa (BRICS) nations account for one-quarter of the world's land area, having more than 40% of the world's population, and only one-quarter of the world gross national income. Hence the study and review of waste electrical and electronic equipment management systems in BRICS nations is of relevance. It has been observed from the literature that there are studies available comparing two or three country's waste electrical and electronic equipment status, while the study encompassing the BRICS nations considering in a single framework is scant. The purpose of this study is to analyse the existing waste electrical and electronic equipment management systems and status of compliance to Basel convention in the BRICS nations, noting possible lessons from matured systems, such as those in the European Union EU) and USA. The study introduced a novel framework for a waste electrical and electronic equipment management system that may be adopted in BRICS nations and revealed that BRICS countries have many similar types of challenges. The study also identified some significant gaps with respect to the management systems and trans-boundary movement of waste electrical and electronic equipment, which may attract researchers for further research. © The Author(s) 2016.

Solidarity Action in Global Labor Networks. Four Cases of Workplace Organizing at Foreign Affiliates in the Global South

Directory of Open Access Journals (Sweden)

Peter Wad

2014-03-01

Full Text Available Globalization transforms workforces of transnational corporation from predominantly home countrydominated workforces into foreign-dominated, multinational workforces. Thus, the national grounding of trade unions as the key form of labor organizing is challenged by new multinational compositions and cross-border relocations of corporate employment affecting working conditions of employees and trade unions in local places. We assume that economic globalization is characterized by expanding global corporate network of vertically and horizontally integrated (equity-based and disintegrated (nonequity-based value chains. We also assume that globalization can both impede and enable labor empowerment. Based on these premises the key question is, how can labor leverage effective power against management in global corporate networks? This question is split into two subquestions: a How can labor theoretically reorganize from national unions and industrial relations institutions into global labor networks that allow prolabor improvement in global workplaces? b How and why has labor in a globalized economy secured the core International Labor Organization (ILO international labor right to organize companies and conduct collective bargaining? The Global Labor Network perspective is adopted as an analytical framework. Empirically, a comparative case methodology is applied comprising four more or less successful industrial disputes where labor achieved the right to organize and undertake collective bargaining. The disputes took place in affiliated factories of foreign transnational corporations located in Malaysia, the Philippines, Sri Lanka, and Turkey. The conclusion is that the combination of global labor capabilities and global labor strategizing must generate strategic labor power that adequately matches the weaknesses of the counterpart’s global corporate network in order to achieve prolabor outcomes. The most efficient solidarity action was leveraged

2018-01-01

Tuberculosis (TB) remains the most common cause of infectious disease deaths worldwide. What is perhaps less appreciated is that the caseload of tuberculosis patients in South Asia is staggering.South Asia has almost 40% of the global TB burden with 4,028,165 cases in 2015. This region also has a disproportionate share of TB deaths (681,975 deaths, 38% of the global burden). Worldwide just 12.5% of TB cases are in HIV positive individuals, but much research and investment has focused on HIV-associated TB. Only 3.5% of patients with tuberculosis in South Asia have HIV co-infection. Not surprisingly with such a huge burden of disease, this region has an estimated 184,336 multi drug resistant (MDR) cases among notified TB cases which accounts for a third of global MDR burden. Crucially, at least 70% of the estimated MDR cases remain untreated in this region and MDR treatment success ranged from only 46% for India to 88% for Sri Lanka in the 2012 cohort that received treatment. This region represents many of the drivers of the modern TB epidemic: rapid urbanization and high density populations with dramatically rising incidence of diabetes, a burgeoning and largely unregulated private sector with escalating drug resistance and high air pollution both outdoor and household. From bacterial biochemistry to policy implementation, we suggest ways in which South Asia can seize the opportunity lead global TB elimination by demonstrating feasibility in some of the world's most densely populated cities and remotest reaches of the Himalayas. Clearly political will is essential, but we cannot defeat TB without understanding how to eliminate it in South Asia.

In the current United Nations efforts to plan for post 2015-Millennium Development Goals, global partnership to address non-communicable diseases (NCDs) has become a critical goal to effectively respond to the complex global challenges of which inequity in health remains a persistent challenge. Building capacity in terms of well-equipped local researchers and service providers is a key to bridging the inequity in global health. Launched by Penn State University in 2014, the Pan University Network for Global Health responds to this need by bridging researchers at more than 10 universities across the globe. In this paper we outline our framework for international and interdisciplinary collaboration, as well the rationale for our research areas, including a review of these two themes. After its initial meeting, the network has established two central thematic priorities: 1) urbanization and health and 2) the intersection of infectious diseases and NCDs. The urban population in the global south will nearly double in 25 years (approx. 2 billion today to over 3.5 billion by 2040). Urban population growth will have a direct impact on global health, and this growth will be burdened with uneven development and the persistence of urban spatial inequality, including health disparities. The NCD burden, which includes conditions such as hypertension, stroke, and diabetes, is outstripping infectious disease in countries in the global south that are considered to be disproportionately burdened by infectious diseases. Addressing these two priorities demands an interdisciplinary and multi-institutional model to stimulate innovation and synergy that will influence the overall framing of research questions as well as the integration and coordination of research.

Discourses of positionality and the challenges of democratization in the global south: The case of Nepal and Cameroon

Directory of Open Access Journals (Sweden)

Jacob Thorsen

2012-03-01

Full Text Available In this article, we argue that to conceptually and empirically grasp the dynamics and challenges of processes of civic participation, i.e., the deliberation and empowerment of disenfranchised and marginalized populations in the Global South, communication for social change scholars need to pay more attention to three issues: the quality of citizens’ self-perceptions in relation to their local milieu, inter-citizen perceptions and relations at the local level and lastly, the attendant consequences of these on citizens’ sense of efficacy. To grasp and comprehend the interplay of these three issues, we propose the adoption of Floya Anthias’ concept of narratives of location and positionality and demonstrate the heuristic vitality of this notion through a discussion of some local discourses of positionality in Nepal and Cameroon.

Does China and Africa South-South cooperation lead to economic development in Africa?

Directory of Open Access Journals (Sweden)

Nonfodji, P.

2013-03-01

Full Text Available Since a few decades now Chinese enterprises’ investments abroad have seen a continuous and steady ascension. At first cautious and just across the Chinese national borders, these investments, slowly but surely, spread like a sheet of water that seeps into the heart of each continent on the globe. This global infiltration of Chinese companies coincides with the popularity in the use of the expression “South-South Cooperation” to characterize a type of relations between countries categorized as being “developing”. Accordingly this paper seeks to examine the role of the use of this concept as a “channel to achieve common development” in the context of Chinese enterprises’ outward direct investments in Africa adopting insights from international business production theories combined with an historical analysis of the notion of South-South Cooperation. Drawing on primary data gathered during my fieldwork in China in the period stretching from December 2011 to February 2012 and secondary data sources, it is argued that these Chinese investments supported by the Chinese government rhetoric on South-South cooperation, cannot lead to significant economic development in Africa like it has happened in China in the eighties. Rather and at most Chinese investments in Africa show some “trickle-down” effects characterised by very limited economic development in scattered localities throughout the African continent.

Studentification in Bloemfontein, South Africa

Directory of Open Access Journals (Sweden)

Ackermann Anton

2016-03-01

Full Text Available Studentification is a global phenomenon that has been prominent in urban geographical discourse since the large-scale expansion of higher education in the early 1990s. In many developed and developing world countries, expansion in student enrolment has outstripped the ability of institutions of higher learning to provide adequate accommodation. Similar trends have been recorded in South Africa. The task of this paper is to investigate studentification as experienced in one of South Africa’s secondary cities. The paper draws attention to the economic, socio-cultural, and physical characteristics of this form of student housing on host locations. It is argued that studentification holds both positive and negative impacts for the host communities of Bloemfontein. Finally, it is suggested that studentification in South Africa requires greater research attention.

Global Model of Time-Modulated Electronegative Discharges for Neutral Radical and Electron Temperature Control

Science.gov (United States)

Kim, Sungjin; Lieberman, M. A.; Lichtenberg, A. J.

2003-10-01

Control and reduction of neutral radical flux/ion flux ratio and electron temperature Te is required for next generation etching in the microelectronics industry. We investigate time-modulated power for these purposes using a volume-averaged (global) oxygen discharge model, We consider pressures of 10-50 mTorr and plasma densities of 10^10-10^11 cm-3.

Brazil in Regional and Global Governance: Foreign Policy, Leadership and UNASUR

Directory of Open Access Journals (Sweden)

Gregory Chin

2016-09-01

Full Text Available This article examines the role of Brazil as a source of international governance innovation during the Lula da Silva and early Rousseff presidencies (2003–12. The analysis details some of Brazil’s main contributions to regional and global governance, and how these contributions are rooted in ideational and normative innovation and its imaginative, nonconformist, status quo–altering foreign policy of the period. Although Brazil was not, and is not, a “new actor” per se in global governance, it did take unprecedented and dramatic strides between 2003 and 2012 to redefine the multilateral agenda and reshape institutional arrangements for international cooperation and conflict management in South America. At the global level, Brazil launched new platforms for international cooperation, including with the other BRICS countries of Russia, India, China and South Africa. The regional trends are examined in the case of the Union of South American Nations (UNASUR, and the innovations that Brazil spearheaded and supported in international security and health cooperation. However, Brazil’s contributions gain greater salience as part of the broader processes of global change where international power is becoming increasingly diffused and decentralized.

Global timber trade pattern: the cards have changed

2011-01-01

Since the 1960s, the global timber trade has gradually evolved from a South-North trade to a South-South trade, with an acceleration of the phenomenon in the mid 1990s. Nowadays, Asia consumes more than 70% (in round wood equivalent) of the forest products originating from the tropics. Africa becomes the new frontier for the supplies of wood material for Asian giants, which now source raw wood from all over the world. Since the mid 1990s, the dynamics of the tropical timber trade have been in...

Competitive intelligence in emerging economies: A comparative study between Brazil and South Africa

Directory of Open Access Journals (Sweden)

2015-07-01

Full Text Available Competitive intelligence (CI has long been recognised as a strategic management tool that could enhance competitiveness. CI is expected to play an essential developmental role in emerging economies. The need to enhance companies’ competitiveness has grown rapidly. CI is essential, and will increasingly be a challenge in the years to come, especially for emerging economies. This article will compare CI activities in South Africa with CI activities in Brazil. Companies in these two countries have faced increased environmental uncertainty and increasingly there is a need to compete. A questionnaire survey methodology was used where questionnaires were administered to CI experts in organisations in South Africa and Brazil. The findings of the study revealed that only a limited number of organisations in Brazil and South Africa recognise the importance of a CI unit. It was also interesting to note that the CI function is more mature in South Africa than in Brazil. As Brazil and South Africa become more integrated into the global economy, it stands to reason that the global economy will have more of an impact on the countries’ economies. To this end it has become more crucial to monitor global events and trends and it is very important for both countries to develop a CI culture.

Conservation concern regarding the overharvest of global shark populations for meat and fin consumption largely surrounds documented deleterious ecosystem effects, but may be further supported by improved knowledge of possibly high levels in their edible tissues (particularly meat) of the neurotoxin, methylmercury (CH3Hg). For many regions, however, little data exist on shark tissue Hg concentrations, and reasons for Hg variation within and among species or across regions are poorly understood. We quantified total Hg (THg) in 17 shark species (total n=283) from the east coast of South Africa, a top Hg emitter globally. Concentrations varied from means of around 0.1 mg kg(-1) dry weight (dw) THg in hardnose smoothhound (Mustelus mosis) and whale (Rhincodon typus) sharks to means of over 10 mg kg(-1) dw in shortfin mako (Isurus oxyrinchus), scalloped hammerhead (Sphyrna lewini), white (Carcharodon carcharias) and ragged-tooth (Carcharias taurus) sharks. These sharks had higher THg levels than conspecifics sampled from coastal waters of the North Atlantic and North, mid-, and South Pacific, and although sampling year and shark size may play a confounding role, this result suggests the potential importance of elevated local emissions. Values of THg showed strong, species-specific correlations with length, and nearly half the remaining variation was explained by trophic position (using nitrogen stable isotopes, δ(15)N), whereas measures of foraging habitat (using carbon stable isotopes, δ(13)C) were not significant. Mercury concentrations were above the regulatory guidelines for fish health effects and safe human consumption for 88% and 70% of species, respectively, suggesting on-going cause for concern for shark health, and human consumers of shark meat.

Full Text Available Rye (Secale cereale L. serves as an alternative host of Pyrenophora tritici-repentis (PTR the cause of tan spot on wheat. Rye is cultivated as a forage or cover crop and overlaps with a significant portion of wheat acreage in the U.S. northern Great Plains; however, it is not known whether the rye crop influences the evolution of PTR races. We evaluated a global collection of 211 rye accessions against tan spot and assessed the diversity in PTR population on rye in South Dakota. All the rye genotypes were inoculated with PTR races 1 and 5, and infiltrated with Ptr ToxA and Ptr ToxB, at seedling stage. We observed 21% of the genotypes exhibited susceptibility to race 1, whereas, 39% were susceptible to race 5. All 211 accessions were insensitive to both the Ptr toxins. It indicates that though rye exhibits diversity in reaction to tan spot, it lacks Ptr ToxA and ToxB sensitivity genes. This suggests that unknown toxins or other factors can lead to PTR establishment in rye. We characterized the race structure of 103 PTR isolates recovered from rye in South Dakota. Only 22% of the isolates amplified Ptr ToxA gene and were identified as race 1 based on their phenotypic reaction on the differential set. The remaining 80 isolates were noted to be race 4. Our results show that races 1 and 4 are prevalent on rye in South Dakota with a higher frequency of race 4, suggesting a minimal role of rye in the disease epidemiology.

Global patterns of evolutionary distinct and globally endangered amphibians and mammals.

Directory of Open Access Journals (Sweden)

Kamran Safi

Full Text Available BACKGROUND: Conservation of phylogenetic diversity allows maximising evolutionary information preserved within fauna and flora. The "EDGE of Existence" programme is the first institutional conservation initiative that prioritises species based on phylogenetic information. Species are ranked in two ways: one according to their evolutionary distinctiveness (ED and second, by including IUCN extinction status, their evolutionary distinctiveness and global endangerment (EDGE. Here, we describe the global patterns in the spatial distribution of priority ED and EDGE species, in order to identify conservation areas for mammalian and amphibian communities. In addition, we investigate whether environmental conditions can predict the observed spatial pattern in ED and EDGE globally. METHODS AND PRINCIPAL FINDINGS: Priority zones with high concentrations of ED and EDGE scores were defined using two different methods. The overlap between mammal and amphibian zones was very small, reflecting the different phylo-biogeographic histories. Mammal ED zones were predominantly found on the African continent and the neotropical forests, whereas in amphibians, ED zones were concentrated in North America. Mammal EDGE zones were mainly in South-East Asia, southern Africa and Madagascar; for amphibians they were in central and south America. The spatial pattern of ED and EDGE was poorly described by a suite of environmental variables. CONCLUSIONS: Mapping the spatial distribution of ED and EDGE provides an important step towards identifying priority areas for the conservation of mammalian and amphibian phylogenetic diversity in the EDGE of existence programme.

Bougher, S. W.; Engel, S.; Hinson, D. P.; Murphy, J. R.

2003-01-01

The Mars Global Surveyor (MGS) Radio Science (RS) experiment employs an ultrastable oscillator aboard the spacecraft. The signal from the oscillator to Earth is refracted by the Martian ionosphere, allowing retrieval of electron density profiles versus radius and geopotential. The present analysis is carried out on five sets of occultation measurements: (1) four obtained near northern summer solstice (Ls = 74-116, near aphelion) at high northern latitudes (64.7-77.6N), and (2) one set of profiles approaching equinox conditions (Ls = 135- 146) at high southern latitudes (64.7-69.1S). Electron density profiles (95 to 200 km) are examined over a narrow range of solar zenith angles (76.5-86.9 degrees) for local true solar times of (1) 3-4 hours and (2) 12.1 hours. Variations spanning 1-Martian year are specifically examined in the Northern hemisphere.

Joint spatiotemporal variability of global sea surface temperatures and global Palmer drought severity index values

Science.gov (United States)

Apipattanavis, S.; McCabe, G.J.; Rajagopalan, B.; Gangopadhyay, S.

2009-01-01

Dominant modes of individual and joint variability in global sea surface temperatures (SST) and global Palmer drought severity index (PDSI) values for the twentieth century are identified through a multivariate frequency domain singular value decomposition. This analysis indicates that a secular trend and variability related to the El Niño–Southern Oscillation (ENSO) are the dominant modes of variance shared among the global datasets. For the SST data the secular trend corresponds to a positive trend in Indian Ocean and South Atlantic SSTs, and a negative trend in North Pacific and North Atlantic SSTs. The ENSO reconstruction shows a strong signal in the tropical Pacific, North Pacific, and Indian Ocean regions. For the PDSI data, the secular trend reconstruction shows high amplitudes over central Africa including the Sahel, whereas the regions with strong ENSO amplitudes in PDSI are the southwestern and northwestern United States, South Africa, northeastern Brazil, central Africa, the Indian subcontinent, and Australia. An additional significant frequency, multidecadal variability, is identified for the Northern Hemisphere. This multidecadal frequency appears to be related to the Atlantic multidecadal oscillation (AMO). The multidecadal frequency is statistically significant in the Northern Hemisphere SST data, but is statistically nonsignificant in the PDSI data.

Full Text Available This is a study that uses data from a national survey of multicultural and multilingual Christian congregations in South Africa to examine the institutional factors that support the dominance of English in formerly segregated churches without a formal language policy. Data were collected by qualitative methods on the levels and types of linguistic integration (as well as racial and cultural incorporation in each of 60 congregations from nine Christian denominations across South Africa. The patterns found are best explained in terms of the articulation of formal and popular ideologies that contribute to institutional isomorphism across state and civil institutions.

Simulating the characteristics of tropical cyclones over the South West Indian Ocean using a Stretched-Grid Global Climate Model

Science.gov (United States)

Maoyi, Molulaqhooa L.; Abiodun, Babatunde J.; Prusa, Joseph M.; Veitch, Jennifer J.

2018-03-01

Tropical cyclones (TCs) are one of the most devastating natural phenomena. This study examines the capability of a global climate model with grid stretching (CAM-EULAG, hereafter CEU) in simulating the characteristics of TCs over the South West Indian Ocean (SWIO). In the study, CEU is applied with a variable increment global grid that has a fine horizontal grid resolution (0.5° × 0.5°) over the SWIO and coarser resolution (1° × 1°—2° × 2.25°) over the rest of the globe. The simulation is performed for the 11 years (1999-2010) and validated against the Joint Typhoon Warning Center (JTWC) best track data, global precipitation climatology project (GPCP) satellite data, and ERA-Interim (ERAINT) reanalysis. CEU gives a realistic simulation of the SWIO climate and shows some skill in simulating the spatial distribution of TC genesis locations and tracks over the basin. However, there are some discrepancies between the observed and simulated climatic features over the Mozambique channel (MC). Over MC, CEU simulates a substantial cyclonic feature that produces a higher number of TC than observed. The dynamical structure and intensities of the CEU TCs compare well with observation, though the model struggles to produce TCs with a deep pressure centre as low as the observed. The reanalysis has the same problem. The model captures the monthly variation of TC occurrence well but struggles to reproduce the interannual variation. The results of this study have application in improving and adopting CEU for seasonal forecasting over the SWIO.

Competitive intelligence: An instrument to enhance South Africa’s competitiveness

Directory of Open Access Journals (Sweden)

Wilma Viviers

2014-10-01

Full Text Available The case for Competitive Intelligence (CI as an instrument that can enhance the competitiveness of South African companies and South Africa as a country is strong. Various global competitive rankings measurements have indicated over a number of years the areas in which competitiveness is lacking. Moreover, these rankings have indicated that South Africa has failed to improve its position year on year. The fact that the world is becoming increasingly competitive for South African entities is undisputed. Coupled with a fluctuating exchange rate and the country’s geographical proximity, this poses unique challenges facing South African managers who have to deal with various regulations and legislative matters. In order to create and sustain an effective knowledge economy and to enhance global competitiveness, South Africa however has to put appropriate strategies/measures in place to stimulate, encourage and grow knowledge practices. Competitive Intelligence (CI as a means of making more sense of the competitive business environment and to identify opportunities and risks in time to act upon can be effectively used as a means to enhance competitiveness. Valuable lessons from successful CI practices in the business sector and government can be learnt from elsewhere in the world. CI should be investigated and adapted for South Africa’s business environment. It is therefore the aim of this article to first attempt to describe the role of CI in enhancing competitiveness, specifically in South Africa and secondly, to stimulate thought on how to secure momentum in enhancing CI as an academic field by developing relevant CI courses as well as demonstrating the value of CI to companies in South Africa through research and collaboration between academics and the private and public sectors.

The possible response of forest ecosystems of south taiga at the south of Valdai Hills on projected future global warming was assessed using analysis of pollen, plant macrofossil and radiocarbon data from four profiles of buried organic sediments of the last interglacial and several cores from modern raised bogs and two small forest mires in the Central Forest State Natural Biosphere Reserve (CFSNBR; Twer region, Russia). The future pattern of climatic conditions for the period up to 2100 was derived using the data of A2, B1 and A1B emission scenarios calculated by the global climatic model ECHAM5-MPIOM (Roeckner E et al 2003 The Atmospheric General Circulation Model ECHAM 5. PART I: Model Description, Report 349 (Hamburg: Max-Planck Institute for Meteorology) p 127). The paleoclimatic reconstructions showed that the optimum of the Holocene (the Late Atlantic period, 4500-4800 {sup 14}C yr BP) and the optimal phases of the last interglacial (Mikulino, Eemian, 130 000-115 000 yr BP) can be considered as possible analogs for projected climatic conditions of the middle and the end of the 21st century, respectively. The climate of the CFSNBR during the Holocene climatic optimum was characterized by higher winter (about 3 deg. C higher than at present) and summer temperatures (about 1 deg. C higher than present values). Precipitation was close to present values (about 600-800 mm yr{sup -1}). Vegetation was represented by mixed coniferous and broad-leaved forest. In the warmest phases of the last interglacial the winter temperature was 5-8 deg. C higher than present values. The summer temperatures were also about 2-4 deg. C higher. Broad-leaved and hornbeam trees were the dominant tree species in vegetation cover.

The 137 Cs activities were determined for seawater samples from the East Caroline, Coral Sea, New Hebrides, South Fiji and Tasman Sea (two stations) Basins of the western South Pacific Ocean by γ spectrometry using a low background Ge detector. The 137 Cs activities ranged from 1.4 to 2.3 Bq m -3 over the depth interval 0-250 m and decreased exponentially from the subsurface to 1000 m depth. The distribution profiles of 137 Cs activity at these six western South Pacific Ocean stations did not differ from each other significantly. There was a remarkable difference for the vertical profiles of 137 Cs activity between the East Caroline Basin station in this study and the GEOSECS (Geochemical Ocean Sections Study) station at the same latitude in the Equatorial Pacific Ocean; the 137 Cs inventory over the depth interval 100-1000 m increased from 400 ± 30 Bq m -2 to 560 ± 30 Bq m -2 during the period from 1973 to 1992. The total 137 Cs inventories in the western South Pacific Ocean ranged from 850 ± 70 Bq m -2 in the Coral Sea Basin to 1270 ± 90 Bq m -2 in the South Fiji Basin. Higher 137 Cs inventories were observed at middle latitude stations in the subtropical gyre than at low latitude stations. The 137 Cs inventories were 1.9-4.5 times (2.9 ± 0.7 on average) and 1.7-4.3 times (3.1 ± 0.7 on average) higher than that of the expected deposition density of atmospheric global fallout at the same latitude and that of the estimated 137 Cs deposition density in 10 o latitude by 10 deg. longitude grid data obtained by Aoyama et al. [Aoyama M, Hirose K, Igarashi Y. Re-construction and updating our understanding on the global weapons tests 137 Cs fallout. J Environ Monit 2006;8:431-438], respectively. The possible processes for higher 137 Cs inventories in the western South Pacific Ocean than that of the expected deposition density of atmospheric global fallout may be attributable to the inter-hemisphere dispersion of the atmospheric nuclear weapons testing 137 Cs from

Electron Flux Dropouts at L ˜ 4.2 From Global Positioning System Satellites: Occurrences, Magnitudes, and Main Driving Factors

Dropouts in electron fluxes at L ˜ 4.2 were investigated for a broad range of energies from 120 keV to 10 MeV, using 16 years of electron flux data from Combined X-ray Dosimeter on board Global Positioning System (GPS) satellites. Dropouts were defined as flux decreases by at least a factor 4 in 12 h, or 24 h during which a decrease by at least a factor of 1.5 must occur during each 12 h time bin. Such fast and strong dropouts were automatically identified from the GPS electron flux data and statistics of dropout magnitudes, and occurrences were compiled as a function of electron energy. Moreover, the Error Reduction Ratio analysis was employed to search for nonlinear relationships between electron flux dropouts and various solar wind and geomagnetic activity indices, in order to identify potential external causes of dropouts. At L ˜ 4.2, the main driving factor for the more numerous and stronger 1-10 MeV electron dropouts turns out to be the southward interplanetary magnetic field Bs, suggesting an important effect from precipitation loss due to combined electromagnetic ion cyclotron and whistler mode waves in a significant fraction of these events, supplementing magnetopause shadowing and outward radial diffusion which are also effective at lower energies.

KT&G: From Korean monopoly to 'a global name in the tobacco industry'.

Science.gov (United States)

Lee, Kelley; Gong, Lucy; Eckhardt, Jappe; Holden, Chris; Lee, Sungkyu

2017-03-01

Until the late 1980s, the former South Korean tobacco monopoly KT&G was focused on the protected domestic market. The opening of the market to foreign competition, under pressure from the U.S. Trade Representative, led to a steady erosion of market share over the next 10 years. Drawing on company documents and industry sources, this paper examines the adaptation of KT&G to the globalization of the South Korean tobacco industry since the 1990s. It is argued that KT&G has shifted from a domestic monopoly to an outward-looking, globally oriented business in response to the influx of transnational tobacco companies. Like other high-income countries, South Korea has also seen a decline in smoking prevalence as stronger tobacco control measures have been adopted. Faced with a shrinking domestic market, KT&G initially focused on exporting Korean-manufactured cigarettes. Since the mid-2000s, a broader global business strategy has been adopted including the building of overseas manufacturing facilities, establishing strategic partnerships and acquiring foreign companies. Trends in KT&G sales suggest an aspiring transnational tobacco company poised to become a major player in the global tobacco market.

Non-communicable diseases in South Asia: contemporary perspectives.

Siegel, Karen R; Patel, Shivani A; Ali, Mohammed K

2014-09-01

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

The simulation and analysis of global air traffic is limited due to a lack of simulation tools and the difficulty in accessing data sources. This paper provides a global simulation of aviation operations combining flight plans and real air traffic data with historical commercial city-pair aircraft type and schedule data and global atmospheric data. The resulting capability extends the simulation and optimization functions of NASA's Future Air Traffic Management Concept Evaluation Tool (FACET) to global scale. This new capability is used to present results on the evolution of global air traffic patterns from a concentration of traffic inside US, Europe and across the Atlantic Ocean to a more diverse traffic pattern across the globe with accelerated growth in Asia, Australia, Africa and South America. The simulation analyzes seasonal variation in the long-haul wind-optimal traffic patterns in six major regions of the world and provides potential time-savings of wind-optimal routes compared with either great circle routes or current flight-plans if available.

Ionospheric weather maps using the total electron content (TEC) monitored by ground-based Global Navigation Satellite Systems (GNSS) receivers over South American continent, TECMAP, have been operationally produced by Instituto Nacional de Pesquisas Espaciais's Space Weather Study and Monitoring Program (Estudo e Monitoramento Brasileiro de Clima Especial) since 2013. In order to cover the whole continent, four GNSS receiver networks, (Rede Brasileiro de Monitoramento Contínuo) RBMC/Brazilian Institute for Geography and Statistics, Low-latitude Ionospheric Sensor Network, International GNSS Service, and Red Argentina de Monitoreo Satelital Continuo, in total 140 sites, have been used. TECMAPs with a time resolution of 10 min are produced in 12 h time delay. Spatial resolution of the map is rather low, varying between 50 and 500 km depending on the density of the observation points. Large day-to-day variabilities of the equatorial ionization anomaly have been observed. Spatial gradient of TEC from the anomaly trough (total electron content unit, 1 TECU = 1016 el m-2 (TECU) 80) causes a large ionospheric range delay in the GNSS positioning system. Ionospheric plasma bubbles, their seeding and development, could be monitored. This plasma density (spatial and temporal) variability causes not only the GNSS-based positioning error but also radio wave scintillations. Monitoring of these phenomena by TEC mapping becomes an important issue for space weather concern for high-technology positioning system and telecommunication.

Global genetics and invasion history of the potato powdery scab pathogen, Spongospora subterranea f.sp. subterranea.

Gau, Rebecca D; Merz, Ueli; Falloon, Richard E; Brunner, Patrick C

2013-01-01

Spongospora subterranea f. sp. subterranea (Sss) causes two diseases on potato (Solanum tuberosum), lesions on tubers and galls on roots, which are economically important worldwide. Knowledge of global genetic diversity and population structure of pathogens is essential for disease management including resistance breeding. A combination of microsatellite and DNA sequence data was used to investigate the structure and invasion history of Sss. South American populations (four countries, 132 samples) were consistently more diverse than those from all other regions (15 countries, 566 samples), in agreement with the hypothesis that Sss originated in South America where potato was domesticated. A substantial genetic differentiation was found between root and tuber-derived samples from South America. Estimates of past and recent gene flow suggested that Sss was probably introduced from South America into Europe. Subsequently, Europe is likely to have been the recent source of migrants of the pathogen, acting as a "bridgehead" for further global dissemination. Quarantine measures must continue to be focussed on maintaining low global genetic diversity and avoiding exchange of genetic material between the native and introduced regions. Nevertheless, the current low global genetic diversity of Sss allows potato breeders to select for resistance, which is likely to be durable.

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

Breast cancer in the global south and the limitations of a biomedical framing: a critical review of the literature.

Confortini, Catia C; Krong, Brianna

2015-12-01

Public health researchers are devoting increasing attention to the growing burden of breast cancer in low-and middle-income countries (LMICs), previously thought to be minimally impacted by this disease. A critical examination of this body of literature is needed to explore the assumptions, advantages and limitations of current approaches. In our critical literature review, we find that researchers and public health practitioners predominantly privilege a biomedical perspective focused on patients' adherence (or non-adherence) to 'preventive' practices, screening behaviours and treatment regimens. Cost-effective 'quick fixes' are prioritized, and prevention is framed in terms of individual 'risk behaviours'. Thus, individuals and communities are held responsible for the success of the biomedical system; traditional belief systems and 'harmful' social practices are problematized. Inherently personal, social and cultural experiences of pain and suffering are neglected or reduced to the issue of chemical palliation. This narrow approach obscures the complex aetiology of the disease and perpetuates silence around power relations. This article calls for a social justice-oriented interrogation of the role of power and inequity in the global breast cancer epidemic, which recognizes the agency and experiences of women (and men) who experience breast cancer in the global south.

The era of the next generation of giant telescopes requires not only the advent of new technologies but also the development of novel methods, in order to exploit fully the extraordinary potential they are built for. Global Multi Conjugate Adaptive Optics (GMCAO) pursues this approach, with the goal of achieving good performance over a field of view of a few arcmin and an increase in sky coverage. In this article, we show the gain offered by this technique to an astrophysical application, such as the photometric survey strategy applied to the Chandra Deep Field South as a case study. We simulated a close-to-real observation of a 500 × 500 arcsec2 extragalactic deep field with a 40-m class telescope that implements GMCAO. We analysed mock K-band images of 6000 high-redshift (up to z = 2.75) galaxies therein as if they were real to recover the initial input parameters. We attained 94.5 per cent completeness for source detection with SEXTRACTOR. We also measured the morphological parameters of all the sources with the two-dimensional fitting tools GALFIT. The agreement we found between recovered and intrinsic parameters demonstrates GMCAO as a reliable approach to assist extremely large telescope (ELT) observations of extragalactic interest.

Full Text Available The theme of the first issue is very multi‐disciplinary. It links economics with management by exploring global opportunities through particular local businesses. The European Union, as all of Europe, is now facing grand global challenges that primarily relate to economic issues. As stipulated by H. Sirkin, J. Hemerling and A. Bhattacharya in their world‐famous book: Globality: Competing with Everyone from Everywhere for Everything, in the resent future the European, American and Japanese firms will compete not only with each, other but increasingly with very competitive Chinese, Indian, South American, and even African firms, which currently may seem farfetched (Kotler & Caslione, 2009, p. 29. We believe it is extremely important to recognise global opportunities, which have resulted from globalisation, internationalisation and Europeanisation processes (Wach, 2012, pp. 137‐150 and 298‐299.

Focus: global currents in national histories of science: the "global turn" and the history of science in Latin America.

Science.gov (United States)

McCook, Stuart

2013-12-01

The "global turn" in the history of science offers new ways to think about how to do national and regional histories of science, in this case the history of science in Latin America. For example, it questions structuralist and diffusionist models of the spread of science and shows the often active role that people in Latin America (and the rest of the Global South) played in the construction of "universal" scientific knowledge. It suggests that even national or regional histories of science must be situated in a global context; all too often, such histories have treated global processes as a distant backdrop. At the same time, historians need to pay constant attention to the role of power in the construction of scientific knowledge. Finally, this essay highlights a methodological tool for writing globally inflected histories of science: the method of "following".

Local economic development and globalisation : the international competitiveness of certain South African municipalities / Vincent Monti Malebo Mongake

OpenAIRE

Mongake, Monti Malebo Vincent

2004-01-01

In today's global competitive environment, a city or a town more than ever needs a strategy that articulates how its international competitiveness is to be improved. Since 1994, following its first democratic elections, South Africa started processes of significant local government reform, as well as fast integration into the global economy. These processes will place significant challenges in the way of South Africa's local government (municipalities) since they now not only h...

Infections are a global issue: infection addresses global issues.

Science.gov (United States)

Grobusch, M P; Calleri, G; Bogner, J R

2012-12-01

Infections are of unifying global concern, despite regional differences in disease epidemiology, clinical appearance and the instruments to tackle them. The primary aim of Infection is "to be a forum for the presentation and discussion of clinically relevant information on infectious diseases… from all over the world". To that end, and as a reflection of the global burden of infectious diseases, we intend to increase the number of high-quality contributions from authors addressing the aetiology, pathogenesis, diagnosis and treatment of infectious diseases from outside Europe and the affluent North (Chang et al. Infection 40:359-365, 2012; Misra et al. Infection 40:125-130, 2012). The Editorial Board of Infection envisages the journal as an interface between where infectious diseases meet and mix between "North and South"--i.e., the field of travel medicine--frequently functioning as a sentinel for altered/novel disease activities that are encountered as imported conditions. With the change in generation on the Editorial Board, Infection aims to expand the areas of tropical medicine, travel medicine and global health with its own section editors (GC and MPG). Contributions from outside Europe are actively encouraged.

Enablers towards establishing and growing South Africa's waste to electricity industry.

Science.gov (United States)

Amsterdam, Heinrich; Thopil, George Alex

2017-10-01

In South Africa the electricity generation mix is relatively un-diverse whereas globally the transformation of the sector is advancing rapidly. Coal remains the predominant fuel source and limited success has to date been achieved in the renewable energy sector. The electricity generation sector is therefore hindered from moving towards an electricity generation landscape where alternative fuel sources is utilised. This research is aimed at gaining insight into the enablers that led towards an increasing trend (observed globally) in exploiting waste as a fuel for electricity generation, and to outline the presence of obstacles that hinder separation of waste for electricity use in the South African context. Furthermore it is an attempt at informing what appropriate interventions (operational and policy) may be considered suitable for South Africa to overcome these barriers in order to enable a sustainable South African waste to electricity (WTE) Industry. Findings show that numerous barriers to a WTE exists in the South African context, however overcoming these barriers is not as simple as adopting the European model with the aim to modify the electricity generation mix and waste management landscape. Selected enablers deemed appropriate in the South African context are adapted from the European model, and are greatly influenced by the prevailing socio-economic status of South Africa. Primary enablers identified were, (i) government support is needed especially in the form of subsidisation for green energy, (ii) increase landfill costs through the implementation of a landfill tax, (iii) streamline the process for Independent Private Power Producers (IPPPs) to connect to the national grid with off-take guaranteed and the inclusion of WTE into an electricity roadmap (effectively government's strategy). The proposed enabling interventions would help in overcoming the barriers for a South African WTE industry. Copyright © 2017 Elsevier Ltd. All rights reserved.

The challenges of disaster management in south Asian countries

International Nuclear Information System (INIS)

Qamar-ul-Islam; Anjum, G.A.; Shahzad, M.

2005-01-01

The type of this research work reflects an overview of disasters in South Asian countries. This outlines geographical aspects and institutional structures briefly in each country, and identifies gaps in disaster management regimes. Identified of these gaps is expected to give insights to the media to develop more informal disaster communications in South Asian Countries. Natural disasters have become a severe global problem. Deaths, displacements and damages resulting from natural disasters are colossal. During the 1990s global economic losses from major natural catastrophes averaged more than US $ 40 billion a year. The current Tsunami disaster has broken all previous records particularly in Indonesia, Sri Lanka and India. This paper focuses particularly on sub continental countries in the South Asian countries, how they are managed and mismanaged, and aims to provide condensed resource material on the subject. In such countries issues related to natural disasters are covered under the legal frameworks for environment, land use, water resources and human settlements. The shift from emergency management to disaster preparedness requires coordination between various government building departments and ministries and with other international organization and various community organizations.

Religion, Intersectionality, and Epistemic Habits of Academic Feminism. Perspectives from Global Feminist Theology

Directory of Open Access Journals (Sweden)

Elina Vuola

2017-10-01

Full Text Available This article pays critical attention to the ways in which academic feminism has regarded religion. Issues related to religion and gender have by and large either been ignored or treated quite stereotypically. I have called this phenomenon a simultaneous under- and overestimation of religion. The phenomenon is not global. Feminists of the global south tend to pay much more and more multi-faceted attention to religion than scholars from the global north. I will illustrate this problem through a close reading of intersectionality in feminist research in religion, especially feminist theology. My argument – which can be supported by evidence from historical records – is that what has been called intersectionality since Kimberlé Crenshaw, has in fact been explicitly present in early feminist theology (1970s-. The reason why feminist liberation theologians stressed the interstructuring of gender, class, and race/ethnicity lies in their practical and theoretical cooperation with liberation and feminist theologians from the global south, for example through the Ecumenical Association of Third World Theologians (EATWOT. My article is a critical re-reading of the history of feminist theorizing from the perspective of religious feminists, academic feminist theologians and liberation theologians from both the global north and south (including black and womanist theologians from the USA, Latin America and Africa. My aim is to correct a long-held understanding of the history of feminist theorizing as purely “secular”.

Global Three-Dimensional Ionospheric Data Assimilation Model Using Ground-based GPS and Radio Occultation Total Electron Content

Science.gov (United States)

Jann-Yenq Liu, Tiger; Lin, Chi-Yen; Matsuo, Tomoko; Lin, Charles C. H.; Tsai, Ho-Fang; Chen, Chao-Yen

2017-04-01

An ionospheric data assimilation approach presented here is based on the Gauss-Markov Kalman filter with International Reference Ionosphere (IRI) as the background model and designed to assimilate the total electron content (TEC) observed from ground-based GPS receivers and space-based radio occultation (RO) of FORMOSAT-3/COSMIC (F3/C) or FORMOSAT-7/COSMIC-2 (F7/C2). The Kalman filter consists of the forecast step according to Gauss-Markov process and measurement update step. Observing System Simulation Experiments (OSSEs) show that the Gauss-Markov Kalman filter procedure can increase the accuracy of the data assimilation analysis over the procedure consisting of the measurement update step alone. Moreover, in comparing to F3/C, the dense F7/C2 RO observation can further increase the model accuracy significantly. Validating the data assimilation results with the vertical TEC in Global Ionosphere Maps and that derived from ground-based GPS measurements, as well as the ionospheric F2-peak height and electron density sounded by ionosondes is also carried out. Both the OSSE results and the observation validations confirm that the developed data assimilation model can be used to reconstruct the three-dimensional electron density in the ionosphere satisfactorily.

Competitive intelligence practice in the South African property sector

Directory of Open Access Journals (Sweden)

Tshilidzi E. Nenzhelele

2016-08-01

Full Text Available Background: The South African property sector contributes highly to creating jobs, skills development, poverty reduction and economic growth. Although South Africa dropped in the global competitiveness ranking, the property sector of South Africa remains very competitive. To survive in a competitive sector, firms around the world practice competitive intelligence(CI. Although the use of CI has been examined in other sectors in South Africa, no study on CI practice has been conducted in the property sector. Objectives: The objective of this research was to establish the extent to which the property sector of South Africa practices CI. Method: This research was quantitative in nature and a web-based questionnaire was used to collect data from estate agencies in the South African property sector. Results: The results indicate that the South African property sector is very competitive and estate agencies practice CI to gain competitive advantage and make quality decisions.Moreover, the results reveal that the property sector practice CI legally and ethically. The results indicate that the majority of estate agencies are very small employing at most five employees and make at most 5 million Rands annual turnover. Conclusion: The South African property sector ethically and legally practices CI to gain competitive advantage and to aid in making quality decisions.

Environmental pollution research in South America

Miguel, A.H.

1991-01-01

This article provides and account of published research in environmental pollution carried out in South American institutions within the past 10 years. Because of the broadness of the topic, the continental dimensions of the assignment, and limitations of space and time, the article focuses on environmental research related to air, water, food, and soil. Thus, it is not a complete record, but rather a sample of published pollution research activities. The information here was obtained primarily from Dialog's electronic search of the Pollution Abstracts Database. The article also identifies other environmental problems that need the attention of South American researchers

December-January-February (DJF) rainfall variability in southeastern South America (SESA) is studied in 18 coupled general circulation models from the WCRP/CMIP3 dataset, for present climate and the SRES-A1B climate change scenario. The analysis is made in terms of properties of the first leading pattern of rainfall variability in the region, characterized by a dipole-like structure with centers of action in the SESA and South Atlantic Convergence Zone (SACZ) regions. The study was performed to address two issues: how rainfall variability in SESA would change in a future climate and how much of that change explains the projected increasing trends in the summer mean rainfall in SESA identified in previous works. Positive (negative) dipole events were identified as those DJF seasons with above (below) normal rainfall in SESA and below (above) normal rainfall in the SACZ region. Results obtained from the multi-model ensemble confirm that future rainfall variability in SESA has a strong projection on the changes of seasonal dipole pattern activity, associated with an increase of the frequency of the positive phase. In addition, the frequency increase of positive dipole phase in the twenty first century seems to be associated with an increase of both frequency and intensity of positive SST anomalies in the equatorial Pacific, and with a Rossby wave train-like anomaly pattern linking that ocean basin to South America, which regionally induces favorable conditions for moisture transport convergence and rainfall increase in SESA.

New Fractures, Old Wounds: Africa and the Renewal of South Agency Neue Brüche, alte Wunden: Afrika und die Erneuerung der South agency

Directory of Open Access Journals (Sweden)

Carlos Lopes

2010-01-01

Full Text Available Africa has recently come to the forefront of world politics as part of the emerging South. Its increased prominence in the global discourse as a “new frontier of development” signals the recognition of its economic potential. Indeed, the continent has registered an average 5 per cent annual GDP growth rate over the past decade. However, there is more to the story than that: The rising profile of the African continent also reveals the growing role of a number of its countries in the emergence of a new South agency. It is argued that South–South cooperation is an opportunity. The discussion of the current situation in Africa understood as a continent in all its diversity including sub-Saharan Africa, but also the Maghreb and Egypt, will therefore be placed into this wider context. The renewal of a South agency witnessed over the past decade is somewhat different from the trilateral alliance of Asia–Africa–Latin America formed in the wake of decolonization. Current mega-trends demonstrate that the global South, driven by a number of regional powers, will play a vital role in shaping the twenty-first century. Understanding the complexities of this renewed agency is vital for addressing old wounds that marked the emergence of a South voice in the not-so-distant past. In jüngster Zeit ist Afrika als Teil des emerging South in den Vordergrund der Weltpolitik gerückt. Seine zunehmende Prominenz im globalen Diskurs als new frontier of development signalisiert die Anerkennung des ökonomischen Potenzials des Kontinents. Tatsächlich konnte Afrika im vergangenen Jahrzehnt eine durchschnittliche jährliche BIP-Wachstumsrate in Höhe von 5 Prozent verzeichnen. Aber es geht um mehr: Die wachsende Wahrnehmung des afrikanischen Kontinents ist Ausdruck der immer wichtigeren Rolle einiger afrikanischer Länder bei der Entstehung einer neuen South agency. Die Süd-Süd-Kooperation wird wieder als Möglichkeit erkannt. Die Diskussion der aktuellen Lage

Taxonomy of interstate conflicts: is South America a peaceful region?

Directory of Open Access Journals (Sweden)

Tássio Franchi

2017-08-01

Full Text Available This article revisits theoretical efforts to classify interstate conflicts. It analyses South America and discuss the adequacy of influential interpretations about the intensity of interstate conflicts in the region as compared to global or other regions ones. The literature takes for granted that South America is a peaceful region. Such interpretation results from the indicators adopted. We argue that traditional indicators do not fully capture latent tensions and the actual level of conflicts in the region. The article suggests an alternative taxonomy that better fits the South America context and argues that a research agenda on the extent and nature of interstate conflics is needed.

Prediction of the fate of radioactive material in the South Pacific Ocean using a global high-resolution ocean model

International Nuclear Information System (INIS)

Hazell, Douglas R.; England, Matthew H.

2003-01-01

We investigate the release of radioactive contaminants from Moruroa Atoll in a global high-resolution off-line model. The spread of tracer is studied in a series of simulations with varying release depths and time-scales, and into ocean velocity fields corresponding to long-term annual mean, seasonal, and interannually varying scenarios. In the instantaneous surface release scenarios we find that the incorporation of a seasonal cycle greatly influences tracer advection, with maximum concentrations still found within the French Polynesia region after 10 years. In contrast, the maximum trace is located in the southeast Pacific when long-term annual mean fields are used. This emphasizes the importance of the seasonal cycle in models of pollution dispersion on large scales. We further find that during an El Nino/Southern Oscillation (ENSO) event reduced currents in the region of Moruroa Atoll result in increased concentrations of radioactive material in French Polynesia, as direct flushing from the source is reduced. In terms of the sensitivity to tracer release time-rates, we find that a gradual input results in maximum concentrations in the near vicinity of French Polynesia. This contrasts the instantaneous-release scenarios, which see maximum concentrations and tracer spread across much of the South Pacific Ocean. For example, in as little as seven years radioactive contamination can reach the east coast of Australia diluted by only a factor of 1000 of the initial concentration. A comparison of results is made with previous studies. Overall, we find much higher concentrations of radionuclides in the South Pacific than has previously been predicted using coarser-resolution models

Globalization and pollution: tele-connecting local primary PM2.5 emissions to global consumption.

Globalization pushes production and consumption to geographically diverse locations and generates a variety of sizeable opportunities and challenges. The distribution and associated effects of short-lived primary fine particulate matter (PM 2.5 ), a representative of local pollution, are significantly affected by the consumption through global supply chain. Tele-connection is used here to represent the link between production and consumption activity at large distances. In this study, we develop a global consumption-based primary PM 2.5 emission inventory to track primary PM 2.5 emissions embodied in the supply chain and evaluate the extent to which local PM 2.5 emissions are triggered by international trade. We further adopt consumption-based accounting and identify the global original source that produced the emissions. We find that anthropogenic PM 2.5 emissions from industrial sectors accounted for 24 Tg globally in 2007; approximately 30% (7.2 Tg) of these emissions were embodied in export of products principally from Brazil, South Africa, India and China (3.8 Tg) to developed countries. Large differences (up to 10 times) in the embodied emissions intensity between net importers and exporters greatly increased total global PM 2.5 emissions. Tele-connecting production and consumption activity provides valuable insights with respect to mitigating long-range transboundary air pollution and prompts concerted efforts aiming at more environmentally conscious globalization.

Global competence of employees in Hispanic Enterprises in the south of United States

Directory of Open Access Journals (Sweden)

Mónica Blanco Jimenez

2011-01-01

Full Text Available Developing interculturally competent students who can compete successfully in the global market is one of the challenges for institutions of higher education in the United States. Some researchers think that Colleges and universities must make a deeper commitment to prepare globally competent graduates. A common assumption is that the processes by which people are educated need to be broadly consistent with the way in which organizations operate in a globalizing environment. With this in mind, we turned to managers of Hispanic enterprises to report whether they believed their employees possess the knowledge, skills, attitudes, and experiences deemed necessary for attaining global competency. We developed a questionnaire based on one created by Hunter (2004 to measure global competencies. We sent them to managers of some Hispanic enterprises who are members of the Tucson Hispanic Chamber of Commerce. In our results we found that employees of the Hispanic enterprises that were targeted do not generally have a high level of global competence according to our indicators.

Global plasma oscillations in electron internal transport barriers in TCV

2008-12-15

In the Tokamak a Configuration Variable (TCV) (Hofmann F et al1994 Plasma Phys. Control. Fusion 36 B277), global plasma oscillations have been discovered in fully non-inductively driven plasmas featuring electron internal transport barriers (ITB) with strong ECRH/ECCD. These oscillations are linked to the destabilization and stabilization of MHD modes near the foot of the ITB and can lead to large oscillations of the total plasma current and line-averaged density, among others. They are intrinsically related to the fact that ITBs have large pressure gradients in a region of low magnetic shear. Therefore, the ideal MHD limit is relatively low and infernal modes can be unstable. Depending on the proximity to the ideal limit, small crashes or resistive modes can appear which affect the time evolution of the discharge. Being near marginal stability, the modes can self-stabilize due to the modification of the pressure gradient and local q-profile. The plasma recovers good confinement, reverses shear and the ITB builds up, until a new MHD mode is destabilized. TCV results show that this cycling behaviour can be controlled by modifying the current density or the pressure profiles, either with Ohmic current density perturbation or by modifying the ECH/ECCD power. It is demonstrated that many observations such as q {>=} 2 sawteeth, beta collapses, minor disruptions and oscillation regimes in ITBs can be assigned to the same physics origin: the proximity to the infernal mode stability limit.

In the Tokamak à Configuration Variable (TCV) (Hofmann F et al1994 Plasma Phys. Control. Fusion 36 B277), global plasma oscillations have been discovered in fully non-inductively driven plasmas featuring electron internal transport barriers (ITB) with strong ECRH/ECCD. These oscillations are linked to the destabilization and stabilization of MHD modes near the foot of the ITB and can lead to large oscillations of the total plasma current and line-averaged density, among others. They are intrinsically related to the fact that ITBs have large pressure gradients in a region of low magnetic shear. Therefore, the ideal MHD limit is relatively low and infernal modes can be unstable. Depending on the proximity to the ideal limit, small crashes or resistive modes can appear which affect the time evolution of the discharge. Being near marginal stability, the modes can self-stabilize due to the modification of the pressure gradient and local q-profile. The plasma recovers good confinement, reverses shear and the ITB builds up, until a new MHD mode is destabilized. TCV results show that this cycling behaviour can be controlled by modifying the current density or the pressure profiles, either with Ohmic current density perturbation or by modifying the ECH/ECCD power. It is demonstrated that many observations such as q >= 2 sawteeth, beta collapses, minor disruptions and oscillation regimes in ITBs can be assigned to the same physics origin: the proximity to the infernal mode stability limit.

Examining South Atlantic Subtropical Cyclone Anita using the Satellite-Enhanced Regional Downscaling for Applied Studies Hourly Outputs

Science.gov (United States)

Vaicberg, H.; Palmeira, A. C. P. A.; Nunes, A.

2017-12-01

Studies on South Atlantic cyclones are mainly compromised by scarcity of observations. Therefore, remote sensing and global (re) analysis products are usually employed in investigations of their evolution. However, the frequent use of global reanalysis might difficult the assessment of the characteristics of the cyclones found in South Atlantic. In that regard, studies on "subtropical" cyclones have been performed using the 25-km resolution, Satellite-enhanced Regional Downscaling for Applied Studies (SRDAS), a product developed at the Federal University of Rio de Janeiro in Brazil. In SRDAS, the Regional Spectral Model assimilates precipitation estimates from environmental satellites, while dynamically downscaling a global reanalysis using the spectral nudging technique to maintain the large-scale features in agreement with the regional model solution. The use of regional models in the downscaling of general circulation models provides more detailed information on weather and climate. As a way of illustrating the usefulness of SRDAS in the study of the subtropical South Atlantic cyclones, the subtropical cyclone Anita was selected because of its intensity. Anita developed near Brazilian south/southeast coast, with damages to local communities. Comparisons with available observations demonstrated the skill of SRDAS in simulating such an extreme event.

Satellite-Enhanced Regional Downscaling for Applied Studies: Extreme Precipitation Events in Southeastern South America

Science.gov (United States)

Nunes, A.; Gomes, G.; Ivanov, V. Y.

2016-12-01

Frequently found in southeastern South America during the warm season from October through May, strong and localized precipitation maxima are usually associated with the presence of mesoscale convective complexes (MCCs) travelling across the region. Flashfloods and landslides can be caused by these extremes in precipitation, with damages to the local communities. Heavily populated, southeastern South America hosts many agricultural activities and hydroelectric production. It encompasses one of the most important river basins in South America, the La Plata River Basin. Therefore, insufficient precipitation is equally prejudicial to the region socio-economic activities. MCCs are originated in the warm season of many regions of the world, however South American MCCs are related to the most severe thunderstorms, and have significantly contributed to the precipitation regime. We used the hourly outputs of Satellite-enhanced Regional Downscaling for Applied Studies (SRDAS), developed at the Federal University of Rio de Janeiro in Brazil, in the analysis of the dynamics and physical characteristics of MCCs in South America. SRDAS is the 25-km resolution downscaling of a global reanalysis available from January 1998 through December 2010. The Regional Spectral Model is the SRDAS atmospheric component and assimilates satellite-based precipitation estimates from the NOAA/Climate Prediction Center MORPHing technique global precipitation analyses. In this study, the SRDAS atmospheric and land-surface variables, global reanalysis products, infrared satellite imagery, and the physical retrievals from the Atmospheric Infrared Sounder (AIRS), on board of the NASA's Aqua satellite, were used in the evaluation of the MCCs developed in southeastern South America from 2008 and 2010. Low-level circulations and vertical profiles were analyzed together to establish the relevance of the moisture transport in connection with the upper-troposphere dynamics to the development of those MCCs.

The Materialist Circuits and the Quest for Environmental Justice in ICT’s Global Expansion

Directory of Open Access Journals (Sweden)

Sibo Chen

2016-02-01

Full Text Available This article builds on and contributes to research on the material impacts of Information and Communication Technology and Consumer Electronics (ICT/CE by proposing a holistic framework addressing labour exploitation and environmental destruction in the production, consumption, and disposal of digital devices. Although the emerging media scholarship on digital labour have critically analyzed the material impacts of ICT/CE in terms of labour issues emerged from the production and consumption stages, relatively little research attention has been paid to the end-of-life issues of digital devices and other environmental issues caused by the ICT industry’s global expansion. Based upon previous research on digital labour, environmental management and ecological justice, this article proposes a political economic understanding of the environmental dimension of the ICT industry and how it has contributed to the escalation of environmental crisis and social injustice in developing coun-tries, especially in terms of the urging situation of the global e-waste challenge. The article argues that the critical standpoints taken by political economy of communication and environmental justice re-search provide valuable and promising theoretical connections between labour activism and ecological struggles; and future inquiries on digital economy, in this regard, should combine both perspectives, pay more attention to the enormous social and ecological tensions in the Global South, and make explicit connections between the regressions in labour rights and global environmental justice and ICT’s aggressive and unsustainable expansion.

Seasonal, interannual, and long-term variabilities in biomass burning activity over South Asia.

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

2016-03-01

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

Global Carbon-and-Conservation Models, Global Eco-States? Ecuador’s Yasuní-ITT Initiative and Governance Implications

Directory of Open Access Journals (Sweden)

Conny Davidsen

2013-05-01

Full Text Available The “global carbon age” marks a structural change far beyond the economic realms of implementing carbon trade, affecting the fabric of global environmental governance and its actors. Carbon trade and conservation in the Global South have taken on various forms, and climate change mitigation efforts in light of continued rainforest deforestation are scrambling to establish effective approaches. Ecuador’s Yasuní-ITT Initiative proposes a new global carbon-and-conservation model in the Ecuadorian Amazon that leaves oil reserves of the Yasuní Ishpingo Tambococha Tiputini (ITT oil fields underground, in exchange for international compensation payments that would be based on voluntary contributions of governments and nongovernmental actors in an international conservation partnership and trust fund under the auspices of the United Nations Development Programme. This model suggests far-reaching consequences, as it introduces new global scales for the sharing and management of environmental costs within a framework of neoliberal cost internalization. The analysis in this paper uses the concept of the “ecological state” (Duit, 2008 as a theoretical point of departure to examine the trans-scalar implications of such a carbon-and-conservation model on global governance structures toward a “global ecological state” (or global eco-state.

Caught between the global economy and local bureaucracy: the barriers to good waste management practice in South Africa.

Science.gov (United States)

Godfrey, Linda; Scott, Dianne; Trois, Cristina

2013-03-01

Empirical research shows that good waste management practice in South Africa is not always under the volitional control of those tasked with its implementation. While intention to act may exist, external factors, within the distal and proximal context, create barriers to waste behaviour. In addition, these barriers differ for respondents in municipalities, private industry and private waste companies. The main barriers to implementing good waste management practice experienced by respondents in municipalities included insufficient funding for waste management and resultant lack of resources; insufficient waste knowledge; political interference in decision-making; a slow decision-making process; lack of perceived authority to act by waste staff; and a low priority afforded to waste. Barriers experienced by respondents in private industry included insufficient funding for waste and the resultant lack of resources; insufficient waste knowledge; and government bureaucracy. Whereas, barriers experienced in private waste companies included increasing costs; government bureaucracy; global markets; and availability of waste for recycling. The results suggest that respondents in public and private waste organizations are subject to different structural forces that shape, enable and constrain waste behaviour.

Global analysis of muon decay measurements

International Nuclear Information System (INIS)

Gagliardi, C.A.; Tribble, R.E.; Williams, N.J.

2005-01-01

We have performed a global analysis of muon decay measurements to establish model-independent limits on the space-time structure of the muon decay matrix element. We find limits on the scalar, vector, and tensor coupling of right- and left-handed muons to right- and left-handed electrons. The limits on those terms that involve the decay of right-handed muons to left-handed electrons are more restrictive than in previous global analyses, while the limits on the other nonstandard model interactions are comparable. The value of the Michel parameter η found in the global analysis is -0.0036±0.0069, slightly more precise than the value found in a more restrictive analysis of a recent measurement. This has implications for the Fermi coupling constant G F

Paleohydrology Reconstruction of the Tropical South America for the Past 1.6 Million Years.

The western Atlantic equatorial margin has been recognized as an important part of global climate change. It is responsible for the transfer of moisture to South America and, heat and fresh water to the northern hemisphere. It might hold answers to past and present global climate. We reconstructed the last 1.6 million years of the paleoclimatic record of the Tropical South American to assess a long period of oceanic and atmospheric variability, which still remains unknown to science. Paleoclimate reconstructions of the Tropical South American are determined on a sediment core located on the Brazilian continental slope. High-resolution XRF analyses of Fe, Ti, K and Ca are used to define the paleohydrologic evolution. Here we present elemental ratios of Ti/Ca and Fe/K, to determine variability in Tropical South America. Differences in sediment input observed on Fe/K and Ti/Ca ratios suggest periods of increased chemical weathering and precipitation. Comparison of our data with the Cariaco basin Molybdenum (Mo) records, suggests that the Intertropical Convergence Zone (ITCZ) is triggering wet periods on Tropical South America, distinguishing a clear North-South anti-phase over the last 600 ka. Southward displacement of the ITCZ in the Mid-Pleistocene Transition, indicates changes in the variability mode of the ITCZ N-S excursion, modulating the precipitation over Tropical South America. We also show that extensive northward migration of Antarctic Polar Front induces a drastic change in the Tropical South America hydrological system, triggering long periods of drought, potentially driven by cooler sea surface temperature of the South Atlantic. This study is funded by Capes- IODP 38/2014 and the Duke University.

Bidirectional electron anisotropies in the distant tail: ISEE-3 observations of polar rain

A detailed observational treatment of bidirectional electrons (50 approx.500 eV) in the distant magnetotail (r greater than or equal to 100 R/sub E/) is presented. It is found that electrons in this energy range commonly exhibit strong, field-aligned anisotropies in the tail lobes. Because of large tail motions, the ISEE-3 data provide extensive sampling of both the north and south lobes in rapid succession, demonstrating directly the strong asymmetries that exist between the north and south lobes at any one time. The bidirectional fluxes are found to occur predominantly in the lobe directly connected to the sunward IMF in the open magnetosphere model (north lobe for away sectors and south lobe for toward sectors). Electron anisotropy and magnetic field data are presented which show the transition from unidirectional (sheath) electron populations to bidirectional (lobe) populations. Taken together, the present evidence suggests that the bidirectional electrons that we observe in the distant tail are closely related to the polar rain electrons observed previously at lower altitudes. Furthermore, these data provide strong evidence that the distant tail is comprised largely of open magnetic field lines in contradistinction to some recently advanced models

The MIT-Bates South Hall Ring construction project is now nearly complete. At this time the Energy Compression System, the SHR Injection Line and the South Hall Ring itself are complete. The SHR Extraction Line is complete but has not been connected to the ring. Commissioning with beam of the completed beam lines has been started. The MIT-Bates South Hall Ring (SHR) is an electron storage ring used with the 1 GeV Bates electron accelerator to increase the effective duty factor and luminosity. A beam can be stored for use with an internal target, thus allowing for high duty factor, high luminosity experiments. External beams with high duty factor can be obtained using resonant extraction. The new systems associated with the SHR include the Energy Compression System (ECS), the Injection line, and the Extraction line. The authors have commissioned the ECS, the new injection line and the SHR without RF. This includes transporting beam, measuring beam phase space parameters using critical injection elements including a high voltage electrostatic septum, a fast beam kicker, and storing a beam in the SHR

Psychology and health after apartheid: Or, Why there is no health psychology in South Africa.

Science.gov (United States)

Yen, Jeffery

2016-05-01

As part of a growing literature on the histories of psychology in the Global South, this article outlines some historical developments in South African psychologists' engagement with the problem of "health." Alongside movements to formalize and professionalize a U.S.-style "health psychology" in the 1990s, there arose a parallel, eclectic, and more or less critical psychology that contested the meaning and determinants of health, transgressed disciplinary boundaries, and opposed the responsibilization of illness implicit in much health psychological theorizing and neoliberal discourse. This disciplinary bifurcation characterized South African work well into the postapartheid era, but ideological distinctions have receded in recent years under a new regime of knowledge production in thrall to the demands of the global market. The article outlines some of the historical-political roots of key trends in psychologists' work on health in South Africa, examining the conditions that have impinged on its directions and priorities. It raises questions about the future trajectories of psychological research on health after 20 years of democracy, and argues that there currently is no "health psychology" in South Africa, and that the discipline is the better for it.

European, North American and Australian pipeline companies are busy building pipelines to transport natural gas to power stations throughout South East Asia. Many countries, such as Thailand, Malaysia, Singapore and Indonesia, have economies expanding at more than eight percent a year. Cambodia and Laos are awaiting energy development. Myanmar will not only benefit from the global economic expansion but from the flourishing economies of nearby Thailand and Malaysia which are now investing in neighbouring countries, while their national petroleum companies are starting to operate worldwide. It is the ever expanding rush of industrialisation, urbanisation and the move to raise living standards throughout the region that is accelerating the need for more power stations, both gas and coal-fired, throughout South East Asia.

Is research on soil erosion hazard and mitigation in the Global South still needed? (Alexander von Humbold Medal Lecture)

Science.gov (United States)

Poesen, Jean

2016-04-01

Soil erosion represents a geomorphological and geological hazard that may cause environmental damage (land degradation), property damage, loss of livelihoods and services as well as social and economic disruption. Erosion not only lowers the quality of our soils on site, resulting in a drastic reduction of their ecosystem functions that play a vital role in daily life, but causes also significant sediment-related problems off site. To curb soil erosion problems, a range of soil conservation techniques and strategies have been designed and are being applied. Worldwide, ca. 62 000 research papers on soil erosion and 116 000 on soil conservation have been published (Web of Science, Dec. 2015). The number of such papers dealing with the Global South represents less than 20 % of all papers, despite the fact that many regions in this part of the world face significant soil erosion problems, aggravated by a rapidly growing population and major environmental changes. Given the large number of research papers on this topic, one might therefore conclude that we now know almost everything about the various soil erosion processes and rates, their factors and consequences as well as their control so that little new knowledge can still be added to the vast amount of available information. We refute this conclusion by pointing to some major research gaps that still need to be addressed if we want to use our soils in a more sustainable way. More specifically the following topics need more research attention: 1) improved understanding of both natural and anthropogenic soil erosion processes and their interactions, 2) scaling up soil erosion processes and rates in space and time, and 3) innovative techniques and strategies to prevent or reduce erosion rates. This will be illustrated with case studies from the Global South. If future research focuses on these research gaps, we will 1) better understand processes and their interactions operating at a range of spatial and temporal

Global climate convention

International Nuclear Information System (INIS)

Simonis, U.E.

1991-01-01

The effort of negotiate a global convention on climate change is one of mankind's great endeavours - and a challenge to economists and development planners. The inherent linkages between climate and the habitability of the earth are increasingly well recognized, and a convention could help to ensure that conserving the environment and developing the economy in the future must go hand in hand. Due to growing environmental concern the United Nations General Assembly has set into motion an international negotiating process for a framework convention on climate change. One the major tasks in these negotiations is how to share the duties in reducing climate relevant gases, particularly carbon dioxide (CO 2 ), between the industrial and the developing countries. The results and proposals could be among the most far-reaching ever for socio-economic development, indeed for global security and survival itself. While the negotiations will be about climate and protection of the atmosphere, they will be on fundamental global changes in energy policies, forestry, transport, technology, and on development pathways with low greenhouse gas emissions. Some of these aspects of a climate convention, particularly the distributional options and consequences for the North-South relations, are addressed in this chapter. (orig.)

Astronomy for teachers: A South African Perspective

Science.gov (United States)

de Witt, Aletha; West, Marion; Leeuw, Lerothodi; Gouws, Eldrie

2015-08-01

South Africa has nominated Astronomy as a “flagship science” and aims to be an international Astronomy hub through projects such as the Square Kilometre Array (SKA) and the South African Large Telescope (SALT). These projects open up career opportunities in maths, science and engineering and therefore offers a very real door for learners to enter into careers in science and technology through Astronomy. However, the Trends in International Mathematics and Science Survey (TIMSS), the Global Competitiveness Report (GCR) and Annual National Assessment (ANA) have highlighted that South Africa’s Science and Mathematics education is in a critical condition and that South African learners score amongst the worst in the world in both these subjects. In South Africa Astronomy is generally regarded as the worst taught and most avoided Natural Science knowledge strand, and most teachers that specialised in Natural Sciences, never covered Astronomy in their training.In order to address these issues a collaborative project between the University of South Africa (UNISA) and the Hartebeesthoek Radio Astronomy Observatory (HartRAO) was initiated, which aims to assist teachers to gain more knowledge and skills so that they can teach Astronomy with confidence. By collaborating we aim to ensure that the level of astronomy development will be raised in both South Africa and the rest of Africa.With the focus on Teaching and Learning, the research was conducted within a quantitative paradigm and 600 structured questionnaires were administered to Natural Science teachers in Public primary schools in Gauteng, South Africa. This paper reports the findings of this research and makes recommendations on how to assist teachers to teach Astronomy with confidence.

Platinum replica electron microscopy: Imaging the cytoskeleton globally and locally.

Science.gov (United States)

Svitkina, Tatyana M

2017-05-01

Structural studies reveal how smaller components of a system work together as a whole. However, combining high resolution of details with full coverage of the whole is challenging. In cell biology, light microscopy can image many cells in their entirety, but at a lower resolution, whereas electron microscopy affords very high resolution, but usually at the expense of the sample size and coverage. Structural analyses of the cytoskeleton are especially demanding, because cytoskeletal networks are unresolvable by light microscopy due to their density and intricacy, whereas their proper preservation is a challenge for electron microscopy. Platinum replica electron microscopy can uniquely bridge the gap between the "comfort zones" of light and electron microscopy by allowing high resolution imaging of the cytoskeleton throughout the entire cell and in many cells in the population. This review describes the principles and applications of platinum replica electron microscopy for studies of the cytoskeleton. Copyright © 2017 Elsevier Ltd. All rights reserved.

Integrating global animal health, public health and tropical animal health issues into the veterinary curriculum: a South African/African perspective.

Science.gov (United States)

Swan, G E; Coetzer, J A W; Terblanche, H M

2009-08-01

The globalisation of trade and food, the increased volume and speed of international travel, climate change, and the related escalation of emerging and re-emerging infectious diseases mean that countries are now more interconnected and interdependent than ever before. Africa is beleaguered by a range of endemic infectious and parasitic tropical diseases which, due to its diverse wildlife populations and indigenous livestock, can serve as a reservoir of high-impact or transboundary diseases and play a role in the emergence of disease, particularly at the wildlife, domestic animal and human interfaces. It is therefore essential to integrate animal and public health issues into the veterinary curriculum. Veterinary training in most parts of sub-Saharan Africa has focused on producing veterinarians to serve the livestock sector although socio-economic changes and privatisation of Veterinary Services have caused curriculum adjustments, as have globalisation and the increased risk of the spread of transboundary diseases. In South Africa, undergraduate veterinary training is more clinically oriented than in other regions. Animal and public health issues are covered in the curriculum, although their global relevance is not emphasised. The authors describe the undergraduate veterinary curriculum and summarise post-graduate programmes in South Africa. They also discuss a more comprehensive core-elective approach to the current curriculum and the need to adapt to new challenges facing the profession. Finally, they examine the potential use of innovative technology in undergraduate and post-graduate training and professional development, the importance of regional and international collaboration and the accreditation and recognition of veterinary training.

Phylogeography of Rattus norvegicus in the South Atlantic Ocean

Directory of Open Access Journals (Sweden)

Melanie Hingston

2016-12-01

Full Text Available Norway rats are a globally distributed invasive species, which have colonized many islands around the world, including in the South Atlantic Ocean. We investigated the phylogeography of Norway rats across the South Atlantic Ocean and bordering continental countries. We identified haplotypes from 517 bp of the hypervariable region I of the mitochondrial D-loop and constructed a Bayesian consensus tree and median-joining network incorporating all other publicly available haplotypes via an alignment of 364 bp. Three Norway rat haplotypes are present across the islands of the South Atlantic Ocean, including multiple haplotypes separated by geographic barriers within island groups. All three haplotypes have been previously recorded from European countries. Our results support the hypothesis of rapid Norway rat colonization of South Atlantic Ocean islands by sea-faring European nations from multiple European ports of origin. This seems to have been the predominant pathway for repeated Norway rat invasions of islands, even within the same archipelago, rather than within-island dispersal across geographic barriers.

Smokeless Tobacco and Oral Cancer in South Asia: A Systematic Review with Meta-Analysis

Khan, Z.; Tonnies, J.; Muller, S.; Khan, Z.

2014-01-01

Smokeless tobacco is considered one of the major risk factors for oral cancer. It is estimated that over 90% of the global smokeless tobacco use burden is in South Asia. This paper aims to systematically review publications reporting epidemiological observational studies published in South Asia from 1984 till 2013. Methods. An electronic search in “Medline” and “ISI Web of Knowledge” yielded 734 publications out of which 21 were included in this review. All publications were assessed for quality using a standard quality assessment tool. Effect estimates (odds ratios (OR)) were abstracted or calculated from the given data. A random effects meta-analysis was performed to assess the risk of oral cancer with the use of different forms of smokeless tobacco. Results and Conclusion. The pooled OR for chewing tobacco and risk of oral cancer was 4.7 [3.1-7.1] and for paan with tobacco and risk of oral cancer was 7.1 [4.5-11.1]. The findings of this study suggest a strong causal link between oral cancer and various forms of smokeless tobacco. Public health policies in affected countries should consider SLT specific cessation programs in addition to campaigns and activities incorporated into smoking cessation programs.

137Cs inventories in the water column collected from the South and South China Seas

International Nuclear Information System (INIS)

Yamada, M.; Wang, Z.-L.; Zheng, J.

2006-01-01

Seawater samples were collected in the Sulu and South China Seas and their 137 Cs activities were determined by γ spectrometry. A significant difference in intermediate water 137 Cs activities in the 750-1500 m depth was observed between the Sulu and South China Seas. The 137 Cs inventories in the Sulu Sea was 5.7 times higher than that of the integrated deposition density of atmospheric global fallout at the same latitude of 0-10degN. A possible mechanism controlling this extremely high 137 Cs inventories may be inflows of 137 Cs rich North Pacific Tropical Water and upper North Pacific Intermediate Water through the Luzon Straight from the West Philippine Sea, and lateral transport across the Mindoro Strait into the Sulu Sea, then conveyance into the deep layer in the Sulu Sea basin.

Globalization and international trade in the twenty-first century: opportunities for and threats to the health sector in the south.

Science.gov (United States)

Baris, E; McLeod, K

2000-01-01

Globalization and international trade are important forces at the turn of the century. This article explores how freer international trade will affect developing countries that are net importers of health care goods and services. Four commodities are used as special cases for discussion: pharmaceuticals, health care technologies, pesticides, and tobacco and its related products. The authors discuss the role of international specialized agencies, such as the World Trade Organization, World Health Organization, and World Bank, that are concerned with international trade and its health and health care consequences, and argue that closer collaboration is required among these agencies if the negative effects of trade liberalization on developing countries are to be mitigated. The authors pose a number of research questions that could help in developing proactive policies for the South on the trade of goods and services with harmful effects on health as well as those with potential health and economic benefits.

Full Text Available Water resources, particularly in arid and semi-arid regions of the world are of great concern, as they are closely linked to the wellbeing of humankind. Sophisticated hydrological prediction tools are required to assess climatic and hydrometeorological conditions, as they impact the sustainability of water resources as well as water availability. Research and data collection activities from multi-hydrometeorological sensors (e.g., gauges, radars, satellites form the basis for quantifying the impact of extreme episodes along the hydrologic phases that manifest in terms of the magnitude, duration and frequency of floods, droughts and other hydrometeorological hazards that affect water resources management. A number of hydrometeorological research activities have been reported in the literature by various researchers and research groups globally. This contribution presents (a a review of the hydrometeorology resource landscape in South Africa; (b an analysis of the hydrometeorology services and products in South Africa; (c a review of the hydrometeorological research that has been conducted in South Africa for the last four decades; and (d highlights on some of the challenges facing the sustained advancement of research in hydrometeorology in South Africa.

By altering or eliminating delicate ecological relationships, non-indigenous species are considered a major threat to biodiversity, as well as a driver of environmental change. Global climate change affects ecosystems and ecological communities, leading to changes in the phenology, geographic ranges, or population abundance of several species. Thus, predicting the impacts of global climate change on the current and future distribution of invasive species is an important subject in macroecological studies. The African clawed frog (Xenopus laevis), native to South Africa, possesses a strong invasion potential and populations have become established in numerous countries across four continents. The global invasion potential of X. laevis was assessed using correlative species distribution models (SDMs). SDMs were computed based on a comprehensive set of occurrence records covering South Africa, North America, South America and Europe and a set of nine environmental predictors. Models were built using both a maximum entropy model and an ensemble approach integrating eight algorithms. The future occurrence probabilities for X. laevis were subsequently computed using bioclimatic variables for 2070 following four different IPCC scenarios. Despite minor differences between the statistical approaches, both SDMs predict the future potential distribution of X. laevis, on a global scale, to decrease across all climate change scenarios. On a continental scale, both SDMs predict decreasing potential distributions in the species' native range in South Africa, as well as in the invaded areas in North and South America, and in Australia where the species has not been introduced. In contrast, both SDMs predict the potential range size to expand in Europe. Our results suggest that all probability classes will be equally affected by climate change. New regional conditions may promote new invasions or the spread of established invasive populations, especially in France and Great Britain.

Global Burden of Leptospirosis: Estimated in Terms of Disability Adjusted Life Years.

Directory of Open Access Journals (Sweden)

Paul R Torgerson

Full Text Available Leptospirosis, a spirochaetal zoonosis, occurs in diverse epidemiological settings and affects vulnerable populations, such as rural subsistence farmers and urban slum dwellers. Although leptospirosis can cause life-threatening disease, there is no global burden of disease estimate in terms of Disability Adjusted Life Years (DALYs available.We utilised the results of a parallel publication that reported global estimates of morbidity and mortality due to leptospirosis. We estimated Years of Life Lost (YLLs from age and gender stratified mortality rates. Years of Life with Disability (YLDs were developed from a simple disease model indicating likely sequelae. DALYs were estimated from the sum of YLLs and YLDs. The study suggested that globally approximately 2.90 million DALYs are lost per annum (UIs 1.25-4.54 million from the approximately annual 1.03 million cases reported previously. Males are predominantly affected with an estimated 2.33 million DALYs (UIs 0.98-3.69 or approximately 80% of the total burden. For comparison, this is over 70% of the global burden of cholera estimated by GBD 2010. Tropical regions of South and South-east Asia, Western Pacific, Central and South America, and Africa had the highest estimated leptospirosis disease burden.Leptospirosis imparts a significant health burden worldwide, which approach or exceed those encountered for a number of other zoonotic and neglected tropical diseases. The study findings indicate that highest burden estimates occur in resource-poor tropical countries, which include regions of Africa where the burden of leptospirosis has been under-appreciated and possibly misallocated to other febrile illnesses such as malaria.

South American Monsoon: Recent Droughts in the Context of Changing Global Circulation.

Science.gov (United States)

Seth, A.; Fernandes, K.; Camargo, S. J.

2016-12-01

The 2013-2015 drought in Southeast Brazil led to water shortages in São Paulo, the country's most populous city. The observed drought during austral summers of 2013/2014 and 2014/2015 and related large-scale dynamics are examined. The 2013-2014 precipitation deficits were more concentrated in the state of São Paulo, while in 2014-2015 moderate deficits were seen throughout the region. We find that a persistent warm sea surface temperature (SST) anomaly in the western tropical Pacific Ocean was an important driver of drought via atmospheric teleconnection in the two December-February seasons. The warm SST and associated convective heating initiated a wave train across the South Pacific. The resulting anticyclonic geopotential height anomaly over the southwest Atlantic expanded the westward margin of the South Atlantic high and prevented low-pressure systems from entering southeast Brazil from midlatitudes. This mechanism suggests a hemispheric symmetry to that proposed for the recent California drought. A first look at CMIP5 model projections to examine the role of large scale circulation changes to drought in the Sao Paulo region will be presented.

Nutrition labelling: a review of research on consumer and industry response in the global South

Jessie Mandle

2015-01-01

Full Text Available Background: To identify peer-reviewed research on consumers’ usage and attitudes towards the nutrition label and the food industry's response to labelling regulations outside Europe, North America, and Australia and to determine knowledge gaps for future research. Design: Narrative review. Results: This review identified nutrition labelling research from 20 countries in Asia, Africa, the Middle East, and Latin America. Consumers prefer that pre-packaged food include nutrition information, although there is a disparity between rates of use and comprehension. Consumer preference is for front-of-pack labelling and for information that shows per serving or portion as a reference unit, and label formats with graphics or symbols. Research on the food and beverage industry's response is more limited but shows that industry plays an active role in influencing legislation and regulation. Conclusions: Consumers around the world share preferences with consumers in higher income countries with respect to labelling. However, this may reflect the research study populations, who are often better educated than the general population. Investigation is required into how nutrition labels are received in emerging economies especially among the urban and rural poor, in order to assess the effectiveness of labelling policies. Further research into the outlook of the food and beverage industry, and also on expanded labelling regulations is a priority. Sharing context-specific research regarding labelling between countries in the global South could be mutually beneficial in evaluating obesity prevention policies and strategies.

To assesses the statistical association between exposure to tobacco marketing and tobacco consumption among adolescents in South America, by using data from the Global Youth Tobacco Survey. Using data from the Global Youth Tobacco Survey (GYTS), the exposure to tobacco marketing at the school level was studied from advertising in TV, radio, massive public events and street advertisement. Tobacco behaviour was considered. The total pooled sample used was 134 073 youths from Argentina, Bolivia, Chile, Peru, Brazil, Uruguay, Suriname, Colombia, Guyana, Ecuador, Paraguay and Venezuela. The exposure to tobacco marketing is positively and significantly associated to the probability of youths experimenting with tobacco (at least once in their lifetime). For regular smokers, exposure to tobacco marketing is positively and significantly associated to smoking intensity. These results call for the implementation of strong restrictions on tobacco advertisement of various types in South American countries.

Neotectonic activity in South Africa has only recently received attention despite the fact that a rigorous knowledge of this phenomenon could have a major impact on industrial development within certain areas. Since the early 1980s the Atomic Energy Corporation of South Africa has addressed this specific problem in the process of detailed site investigations for the licensing of six facilities related to the nuclear industry. The data indicates that there is a general correspondence in five selected areas along the South African coast between the development of Quarternary joints/faults and the degree of seismic activity recorded in each geological domain. Finally, the results provide new data that may add to a recent survey of global tectonic stresses. 13 refs., 1 fig

Strong electron bidirectional anisotropies in the distant tail: ISEE 3 observations of polar rain

1986-01-01

A detailed observational treatment of bidirectional electrons (--50 to 50 eV)in the distant magnetotail (rapprox. >100 R/sub E/) is presented. It is found that electrons in this energy range commonly exhibit strong, field-aligned anisotropies in the tail lobes. Because of large tail motions, the ISEE 3 data provide extensive sampling of both the north and south lobes in rapid succession. These data demonstrate directly the strong asymmetries that exist between the north and south lobes at any one time. The bidirectional fluxes are found to occur predominantly in the lobe directly connected to the sunward interplanetary magnetic field in the open magnetosphere model (north lobe for away sectors and south lobe for toward sectors). Electron anisotropy and magnetic field data are presented which show the transition from unidirectional (sheath) electron populations to bidirectional (lobe) populations. Thus we demonstrate the open nature of the distant magnetopause and show that the source of the higher-energy, bidirectional lobe electrons is the tailward directed electron heat flux population in the distant magnetosheath. Taken together, the present evidence suggests that the bidirectional electrons that we observe in the distant tail are closely related to the polar rain electrons observed previously at lower altitudes. Furthermore, these data provide strong evidence that the distant tail is composed largely of open magnetic field lines in contradistinction to some recently advanced models

2014-07-01

Full Text Available The work-life balance (WLB construct as a business imperative has been of growing concern in organisations outside South Africa for the past two decades, particularly given the pressure to create a sustainable global competitive advantage through human capital. Within the last decade this aspect has been prominent in various forums. However, no studies as yet provide insight into the applicability of WLB models to the South African workplace. The present article therefore explores the composition of a WLB system, and analyses constraints on its application under the conditions of the South African labour market.

Explaining ecological clusters of maternal depression in South Western Sydney

Science.gov (United States)

2014-01-01

Background The aim of the qualitative study reported here was to: 1) explain the observed clustering of postnatal depressive symptoms in South Western Sydney; and 2) identify group-level mechanisms that would add to our understanding of the social determinants of maternal depression. Methods Critical realism provided the methodological underpinning for the study. The setting was four local government areas in South Western Sydney, Australia. Child and Family practitioners and mothers in naturally occurring mothers groups were interviewed. Results Using an open coding approach to maximise emergence of patterns and relationships we have identified seven theoretical concepts that might explain the observed spatial clustering of maternal depression. The theoretical concepts identified were: Community-level social networks; Social Capital and Social Cohesion; "Depressed community"; Access to services at the group level; Ethnic segregation and diversity; Supportive social policy; and Big business. Conclusions We postulate that these regional structural, economic, social and cultural mechanisms partially explain the pattern of maternal depression observed in families and communities within South Western Sydney. We further observe that powerful global economic and political forces are having an impact on the local situation.

The aim of the qualitative study reported here was to: 1) explain the observed clustering of postnatal depressive symptoms in South Western Sydney; and 2) identify group-level mechanisms that would add to our understanding of the social determinants of maternal depression. Critical realism provided the methodological underpinning for the study. The setting was four local government areas in South Western Sydney, Australia. Child and Family practitioners and mothers in naturally occurring mothers groups were interviewed. Using an open coding approach to maximise emergence of patterns and relationships we have identified seven theoretical concepts that might explain the observed spatial clustering of maternal depression. The theoretical concepts identified were: Community-level social networks; Social Capital and Social Cohesion; "Depressed community"; Access to services at the group level; Ethnic segregation and diversity; Supportive social policy; and Big business. We postulate that these regional structural, economic, social and cultural mechanisms partially explain the pattern of maternal depression observed in families and communities within South Western Sydney. We further observe that powerful global economic and political forces are having an impact on the local situation. The challenge for policy and practice is to support mothers and their families within this adverse regional and global-economic context.

Global Coupled Model Studies of The Jovian Upper Atmosphere In Response To Electron Precipitation and Ionospheric Convection Within The Auroral Region.

Science.gov (United States)

Millward, G. H.; Miller, S.; Aylward, A. D.

The Jovian Ionospheric Model (JIM) is a global three-dimensional model of Jupiter's coupled ionosphere and thermosphere, developed at University College London. Re- cently, the model has been used to investigate the atmospheric response to electron precipitation within the high-latitude auroral region. A series of simulations have been performed in which the model atmosphere is subjected to monochromatic precipitat- ing electrons of varying number flux and initial energy and, in addition, to various degrees of ionospheric convection. The auroral ionospheric conductivity which re- sults is shown to be strongly non-linear with respect to the incoming electron energy, with a maximum observed for incident particles of initial energy 60 KeV. Electrons with higher energies penetrate the thermospheric region completely, whilst electrons of lower energy (say 10 keV) produce ionisation at higher levels in the atmosphere which are less less condusive to the creation of ionospheric conductivity. Studies of the thermospheric winds with the auroral region show that zonal winds (around the auroral oval) can attain values of around 70% of the driving zonal ion velocity. Also the results show that these large neutral winds are limited in vertical extent to the region of large ionospheric conductivity, tailing off markedly at altitudes above this. The latest results from this work will be presented, and the implications for Jovian magnetospheric-ionospheric coupling will be discussed.

The MIT Bates Accelerator Center is delivering highly polarized electron beams to its South Hall Ring for use in Nuclear Physics Experiments. Circulating electron currents in excess of 200 mA with polarization of 70% are scattered from a highly polarized, but very thin atomic beam source deuterium target. At the electron source a compact diode laser creates photoemission of quasi-CW mA pulses of polarized electrons at low duty factors from a strained GaAs photocathode. Refurbished RF transmitters provide power to the 2856 MHz linac, accelerating the beam to 850 MeV in two passes before injection into the South Hall Ring. In the ring a Siberian snake serves to maintain a high degree of longitudinal polarization at the BLAST scattering target. A Compton laser back-scattering polarimeter measures the electron beam polarization with a statistical acuracy of 6% every 15 minutes.

2014-05-01

Full Text Available One of the responses to the threat of global warming is the Kyoto Protocol and the associated Clean Development Mechanism (CDM to reduce greenhouse gases. South Africa is an ideal country for the implementation of industrial CDM projects, yet lags behind many other countries. This qualitative research determines the factors that cause South Africa to lag other developing countries in the implementation of industrial CDM projects and the interventions that will have the most impact on accelerating implementation. The research involved interviews with 30 experts involved in the South African CDM process. The results identify the factors perceived to be facilitating and inhibiting the use of CDM opportunities and a framework for CDM practitioners to develop an implementation strategy within South African industry is established.

Full Text Available This paper is a brief overview of the evolution of the global automotive industry during the 20th century, with reference to the main manufacturers, oil crises of 1970-1980, and also the global financial and economic crisis that began in 2008. The analyzed period covers the rise of the Asian Continent, beginning with Japan, then South Korea and more recently the emerging countries: China and India. What was predicted 20-25 years ago, became reality: Asia becomes the economic centre of the world, surpassing unexpectedly fast even the Euro-Atlantic area. Regarding Romania, the revival delay of the automobiles industry, led to the loss of the trucks and bus industry, and after a much awaited rehabilitation of car production, this has stuck now at an unsatisfactory level.

Climate Change and North-South Divide. Between and Within

International Nuclear Information System (INIS)

2007-01-01

The traditional North-South divide has persisted through out the negotiations on climate change. Divergent state interests made striking a right balance between development and environmental protection an elusive endeavor as negotiators were striving to adopt a global climate regime. Four principles of international environmental law are of particular concern: the principle of common but differentiated responsibilities, the principle of equity, the precautionary principle, and the principle of sustainable development. With economic development being the overriding priority in developing countries, the negotiations leading to the Kyoto Protocol tend to prove that principles could be interpreted in different ways to fit particular interests. This study explains the confrontations between the North and the South and argues that climate change has by far strengthened the North-South divide both between and within. Accordingly, it concludes that there is a need to devise new principles

Implications of global climate change on water resources of the south Asian region

International Nuclear Information System (INIS)

Lal, M.

1994-01-01

An assessment of future changes in the mean and/or variances of hydrological parameters due to anthropogenic increases in greenhouse gases is much warranted for south Asia for developing adaptive response strategies. The evolution of changes in surface meteorological as well as hydrological parameters in the transient numerical experiments with the current state-of-art coupled climate models holds much promise for a better understanding of the interannual variability of climate and its change on a regional scale. A plausible future hydrological scenario for the south Asian region based on the numerical results obtained from the reference control and greenhouse warming simulations (using the Business-as-Usual scenario of CO 2 concentration in the atmosphere) with the Hamburg climate model is presented in this paper. For validation of regional-scale model-simulated hydrology and the assessment of future changes, analysis of data has been performed for annual mean conditions as well as for two seasons, namely, winter (December to February) and summer (June to August). Their results suggest a rise in annual mean surface air temperature of about 1.0 to 2.5 C over the ocean and between 2.0 to 4.5 C over the land regions of south Asia during the next hundred years. During the NH-winter, surface warming in the land regions of India and China is considerably higher (3.6 C) than during the NH-summer (2.7 C). The model simulates an increase in total (averaged for land points over the study area) annual precipitation of about 16 cm per year in a warmer atmosphere

2017-08-01

Full Text Available Abstract Background Self-interviews, where the respondent rather than the interviewer enters answers to questions, have been proposed as a way to reduce social desirability bias associated with interviewer-led interviews. Computer-assisted self-interviews (CASI are commonly proposed since the computer programme can guide respondents; however they require both language and computer literacy. We evaluated the feasibility and acceptability of using electronic methods to administer quantitative sexual behaviour questionnaires in the Somkhele demographic surveillance area (DSA in rural KwaZulu-Natal, South Africa. Methods We conducted a four-arm randomized trial of paper-and-pen-interview, computer-assisted personal-interview (CAPI, CASI and audio-CASI with an age-sex-urbanicity stratified sample of 504 adults resident in the DSA in 2015. We compared respondents’ answers to their responses to the same questions in previous surveillance rounds. We also conducted 48 cognitive interviews, dual-coding responses using the Framework approach. Results Three hundred forty (67% individuals were interviewed and covariates and participation rates were balanced across arms. CASI and audio-CASI were significantly slower than interviewer-led interviews. Item non-response rates were higher in self-interview arms. In single-paper meta-analysis, self-interviewed individuals reported more socially undesirable sexual behaviours. Cognitive interviews found high acceptance of both self-interviews and the use of electronic methods, with some concerns that self-interview methods required more participant effort and literacy. Conclusions Electronic data collection methods, including self-interview methods, proved feasible and acceptable for completing quantitative sexual behaviour questionnaires in a poor, rural South African setting. However, each method had both benefits and costs, and the choice of method should be based on context-specific criteria.

Aerosol-Cloud Interactions in the South-East Atlantic: Knowledge Gaps, Planned Observations to Address Them, and Implications for Global Climate Change Modeling

Southern Africa produces almost a third of the Earth's biomass burning (BB) aerosol particles, yet the fate of these particles and their influence on regional and global climate is poorly understood. Particles lofted into the mid-troposphere are transported westward over the South-East (SE) Atlantic, home to one of the three permanent subtropical Stratocumulus (Sc) cloud decks in the world. The stratocumulus "climate radiators" are critical to the regional and global climate system. They interact with dense layers of BB aerosols that initially overlay the cloud deck, but later subside and are mixed into the clouds. These interactions include adjustments to aerosol-induced solar heating and microphysical effects. As emphasized in the latest IPCC report, the global representation of these aerosol-cloud interaction processes in climate models is one of the largest uncertainty in estimates of future climate. Hence, new observations over the SE Atlantic have significant implications for global climate change scenarios. We discuss the current knowledge of aerosol and cloud property distributions based on satellite observations and sparse suborbital sampling, and describe planned field campaigns in the region. Specifically, we describe the scientific objectives and implementation of the following four synergistic, international research activities aimed at providing a process-level understanding of aerosol-cloud interactions over the SE Atlantic: 1) ORACLES (Observations of Aerosols above Clouds and their interactions), a five-year investigation between 2015 and 2019 with three Intensive Observation Periods (IOP), recently funded by the NASA Earth-Venture Suborbital Program, 2) CLARIFY-2016 (Cloud-Aerosol-Radiation Interactions and Forcing: Year 2016), a comprehensive observational and modeling programme funded by the UK's Natural Environment Research Council (NERC), and supported by the UK Met Office. 3) LASIC (Layered Atlantic Smoke Interactions with Clouds), a funded

South Atlantic meridional transports from NEMO-based simulations and reanalyses

Mignac, Davi; Ferreira, David; Haines, Keith

2018-02-01

The meridional heat transport (MHT) of the South Atlantic plays a key role in the global heat budget: it is the only equatorward basin-scale ocean heat transport and it sets the northward direction of the global cross-equatorial transport. Its strength and variability, however, are not well known. The South Atlantic transports are evaluated for four state-of-the-art global ocean reanalyses (ORAs) and two free-running models (FRMs) in the period 1997-2010. All products employ the Nucleus for European Modelling of the Oceans (NEMO) model, and the ORAs share very similar configurations. Very few previous works have looked at ocean circulation patterns in reanalysis products, but here we show that the ORA basin interior transports are consistently improved by the assimilated in situ and satellite observations relative to the FRMs, especially in the Argo period. The ORAs also exhibit systematically higher meridional transports than the FRMs, which is in closer agreement with observational estimates at 35 and 11° S. However, the data assimilation impact on the meridional transports still greatly varies among the ORAs, leading to differences up to ˜ 8 Sv and 0.4 PW in the South Atlantic Meridional Overturning Circulation and the MHTs, respectively. We narrow this down to large inter-product discrepancies in the western boundary currents (WBCs) at both upper and deep levels explaining up to ˜ 85 % of the inter-product differences in MHT. We show that meridional velocity differences, rather than temperature differences, in the WBCs drive ˜ 83 % of this MHT spread. These findings show that the present ocean observation network and data assimilation schemes can be used to consistently constrain the South Atlantic interior circulation but not the overturning component, which is dominated by the narrow western boundary currents. This will likely limit the effectiveness of ORA products for climate or decadal prediction studies.

Differential electricity pricing and energy efficiency in South Africa

International Nuclear Information System (INIS)

Kohler, Marcel

2014-01-01

By international standards the economy of South Africa is extremely energy intensive with only a few countries having higher intensities. SA's primary energy use per unit of GDP is amongst the highest in the world. The high energy and electricity intensity of the economy partly reflects SA's resource endowments (in particular the abundance of coal) but is also a function of the historical under-pricing of coal and electricity by the authorities. South African mining and industrial electricity efficiency is particularly concerning and considerably lower than the global average. This paper sets out to fill a significant gap in the South African energy literature by highlighting the importance of incorporating electricity demand factors as part of the country's energy policy and electricity planning horizon. The paper focuses its attention on modelling the electricity consumption of SA's industrial and mining sectors given these account for the lion's share of electricity demand. A differential electricity pricing policy which targets electricity intensive industrial and mining activities (as practised in China since 2004) is viewed by the author to be a superior policy to blanket electricity price increases administered by authorities in an effort to encourage electricity savings and improve energy efficiency in South Africa. - Highlights: • SA's primary energy use per unit of GDP is amongst the highest in the world. • SA industrial electricity efficiency is considerably lower than the global average. • A differential electricity pricing policy which targets electricity intensive activities. • Differential tariffs raise the cost of energy inefficiency and induces energy saving. • Highlights importance of energy demand modelling in electricity supply planning

(Mismanaging labour markets? The decline of the contemporary global labour market for British seafarers.

Directory of Open Access Journals (Sweden)

S. Ruggunan

2010-12-01

Full Text Available Purpose: The purpose of this article is to investigate the ways in which states are still significant actors in creating and shaping the nature and characteristics of global labour markets. My argument is demonstrated through an empirical case study of the global labour market for British seafarers. Problem Investigated: The last 30 years has witnessed a decimation of the number of employed British seafarers, particularly at lower rank levels, such as ratings. I contend that despite Britain's long and rich maritime history, the British state has not acted meaningfully to reverse the decline of British seafarers. The lack of meaningful action I contend is an attempt to crew British owned ships with cheaper seafaring labour from Asia, particularly south east Asia. In so doing the British state has contributed to the decline of a once thriving labour market. There has simultaneously been an upsurge in the employment of seafarers of other nationalities, and thus the creation of new labour markets in countries such as the Philippines. This paper is an attempt to understand some of the factors responsible for the decline of the British labour market for seafarers. Methodology and Approach: This paper is the outcome of a larger qualitative study undertaken for my doctoral thesis in industrial sociology which examined the transformation of the global labour market for South African, Filipino and British seafarers. The methodology consists of in depth interviews with maritime officials and trade union leaders. These were conducted in person in London, United Kingdom between 2005 and 2008. These interviews are supported by extensive literature and documentary research, to validate, support and test claims made by my interviewees. Implications and Value of the Research: The theoretical contribution of this paper is to reinsert the state more critically into the literature on labour markets. Empirically, seafaring labour markets are largely ignored by the

Background South Africa has a significant violence problem. The exposure of girls and women to interpersonal violence is widespread, and the victimization of men, especially to severe and homicidal forms of aggression, is of considerable concern, with male homicide eight times the global rate. In the last two decades, there have been a plethora of South African policies to promote safety. However, indications suggest that the policy response to violence is not coherently formulated, comprehensive, or evenly implemented. Objective This study examines selected South African national legislative instruments in terms of their framing and definition of violence and its typology, vulnerable populations, and prevention. Design This study comprises a directed content analysis of selected legislative documents from South African ministries mandated to prevent violence and its consequences or tasked with the prevention of key contributors to violence. Documents were selected using an electronic keyword search method and analyzed independently by two researchers. Results The legislative documents recognized the high levels of violence, confirmed the prioritization of selected vulnerable groups, especially women, children, disabled persons, and rural populations, and above all drew on criminological perspectives to emphasize tertiary prevention interventions. There is a policy focus on the protection and support of victims and the prosecution of perpetrators, but near absent recognition of men as victims. Conclusions There is a need to broaden the policy framework from primarily criminological and prosecutorial perspectives to include public health contributions. It is likewise important to enlarge the conceptions of vulnerability to include men alongside other vulnerable groups. These measures are important for shaping and resourcing prevention decisions and strengthening primary prevention approaches to violence. PMID:26228996

Collection and analysis of up-to-date and accurate injury surveillance data are a key step in the maturation of trauma systems. Trauma registries have proven to be difficult to establish in low- and middle-income countries owing to the burden of trauma volume, cost, and complexity. To determine whether an electronic trauma health record (eTHR) used by physicians can serve as simultaneous clinical documentation and data acquisition tools. This 2-part quality improvement study included (1) preimplementation and postimplementation eTHR study with assessments of satisfaction by 41 trauma physicians, time to completion, and quality of data collected comparing paper and electronic charting; and (2) prospective ecologic study describing the burden of trauma seen at a Level I trauma center, using real-time data collected by the eTHR on consecutive patients during a 12-month study period. The study was conducted from October 1, 2010, to September 30, 2011, at Groote Schuur Hospital, Cape Town, South Africa. Data analysis was performed from October 15, 2011, to January 15, 2013. The primary outcome of part 1 was data field competition rates of pertinent trauma registry items obtained through electronic or paper documentation. The main measures of part 2 were to identify risk factors to trauma in Cape Town and quality indicators recommended for trauma system evaluation at Groote Schuur Hospital. The 41 physicians included in the study found the electronic patient documentation to be more efficient and preferable. A total of 11 612 trauma presentations were accurately documented and promptly analyzed. Fields relevant to injury surveillance in the eTHR (n = 11 612) had statistically significant higher completion rates compared with paper records (n = 9236) (for all comparisons, P Center (654 [9.0%]), and New Somerset Hospital (400 [5.5%]). Accurate capture and simultaneous analysis of trauma data in low-resource trauma settings are feasible through the integration

As the burden of noncommunicable diseases (NCDs) rises in settings with an equally high burden of infectious diseases in the Global South, a new sense of urgency has developed around research capacity building to promote more effective and sustainable public health and health care systems. In 2010, NCDs accounted for more than 2.06 million deaths in sub-Saharan Africa. Available evidence suggests that the number of people in sub-Saharan Africa with hypertension, a major risk factor for cardiovascular diseases, will increase by 68% from 75 million in 2008 to 126 million in 2025. Furthermore, about 27.5 million people currently live with diabetes in Africa, and it is estimated that 49.7 million people living with diabetes will reside in Africa by 2030. It is therefore necessary to centralize leadership as a key aspect of research capacity building and strengthening in the Global South in ways that enables researchers to claim their spaces in their own locations. We believe that building capacity for transformative leadership in research will lead to the development of effective and appropriate responses to the multiple burdens of NCDs that coexist with infectious diseases in Africa and the rest of the Global South. © 2016 Society for Public Health Education.

Global scale patterns of species diversity for modern deep-sea benthic foraminifera, an important component of the bathyal and abyssal meiofauna, are examined using comparable data from five studies in the Atlantic, ranging over 138° of latitude from the Norwegian Sea to the Weddell Sea. We show that a pattern of decreasing diversity with increasing latitude characterises both the North and South Atlantic. This pattern is confirmed for the northern hemisphere by independent data from the west-central North Atlantic and the Arctic basin. Species diversity in the North Atlantic northwards from the equator is variable until a sharp fall in the Norwegian Sea (ca. 65°N). In the South Atlantic species diversity drops from a maximum in latitudes less than 30°S and then decreases slightly from 40 to 70°S. For any given latitude, North Atlantic diversity is generally lower than in the South Atlantic. Both ecological and historical factors related to food supply are invoked to explain the formation and maintenance of the latitudinal gradient of deep-sea benthic foraminiferal species diversity. The gradient formed some 36 million years ago when global climatic cooling led to seasonally fluctuating food supply in higher latitudes.

North-South Commerce and Oficial Development Aid: Some Contradictory Evidence

Full Text Available That, traditionally, North-South commerce is unfavorably tilted towards the interests of the former is not new: but how is a countries official Aid for Development implicated in the equation? This two-pronged relationship is the subject of the article, which, based on statistics from 1988 to 1995, underlines the importance of the global petroleum trade in the balance between Spainís contribution to Aid for Development and Spainish commercialimport-export gains with countries in the South. By using petroleum as a key ingredient in analyzing the overall relationship, the author demonstrates the quantitative deterioration of Spainish Aid for Development during this period which, in constant prices, revealsthat only in 1991 did the Aid for Development show favorable results for the countries of the South vis a vis the commercial relationship.

Shortages of vaccines for epidemic diseases, such as cholera, meningitis, and yellow fever, have become common over the past decade, hampering efforts to control outbreaks through mass reactive vaccination campaigns. Additionally, various epidemiological, political, and logistical challenges, which are poorly documented in the literature, often lead to delays in reactive campaigns, ultimately reducing the effect of vaccination. In June 2015, a cholera outbreak occurred in Juba, South Sudan, and because of the global shortage of oral cholera vaccine, authorities were unable to secure sufficient doses to vaccinate the entire at-risk population-approximately 1 million people. In this Personal View, we document the first public health use of a reduced, single-dose regimen of oral cholera vaccine, and show the details of the decision-making process and timeline. We also make recommendations to help improve reactive vaccination campaigns against cholera, and discuss the importance of new and flexible context-specific dose regimens and vaccination strategies.
