Economic Aspects of Agricultural and Food Biosecurity in the United States, March 2007

Concerns about biosecurity in the food system raise a variety of issues about how the system is presently organized, why it might be vulnerable, what one could reasonably do to better secure it, and the costs of doing so. After presenting some facts about US agriculture and food, this paper considers three economic aspects of the general problem. One is the global problem, or the way biosecurity measures can affect how countries relate to each other and the global consequences that result. Another is how to best manage the immediate aftermath of a realized threat in order to minimize damage. The third is how to seek to prevent realization of the threat. Some policy alternatives are also presented.

Global surveillance of cancer survival 1995-2009 : analysis of individual data for 25 676 887 patients from 279 population-based registries in 67 countries (CONCORD-2)

BACKGROUND: Worldwide data for cancer survival are scarce. We aimed to initiate worldwide surveillance of cancer survival by central analysis of population-based registry data, as a metric of the effectiveness of health systems, and to inform global policy on cancer control. METHODS: Individual tumour records were submitted by 279 population-based cancer registries in 67 countries for 25·7 million adults (age 15-99 years) and 75 000 children (age 0-14 years) diagnosed with cancer during 1995-2009 and followed up to Dec 31, 2009, or later. We looked at cancers of the stomach, colon, rectum, liver, lung, breast (women), cervix, ovary, and prostate in adults, and adult and childhood leukaemia. Standardised quality control procedures were applied; errors were corrected by the registry concerned. We estimated 5-year net survival, adjusted for background mortality in every country or region by age (single year), sex, and calendar year, and by race or ethnic origin in some countries. Estimates were age-standardised with the International Cancer Survival Standard weights. FINDINGS: 5-year survival from colon, rectal, and breast cancers has increased steadily in most developed countries. For patients diagnosed during 2005-09, survival for colon and rectal cancer reached 60% or more in 22 countries around the world; for breast cancer, 5-year survival rose to 85% or higher in 17 countries worldwide. Liver and lung cancer remain lethal in all nations: for both cancers, 5-year survival is below 20% everywhere in Europe, in the range 15-19% in North America, and as low as 7-9% in Mongolia and Thailand. Striking rises in 5-year survival from prostate cancer have occurred in many countries: survival rose by 10-20% between 1995-99 and 2005-09 in 22 countries in South America, Asia, and Europe, but survival still varies widely around the world, from less than 60% in Bulgaria and Thailand to 95% or more in Brazil, Puerto Rico, and the USA. For cervical cancer, national estimates of 5-year survival range from less than 50% to more than 70%; regional variations are much wider, and improvements between 1995-99 and 2005-09 have generally been slight. For women diagnosed with ovarian cancer in 2005-09, 5-year survival was 40% or higher only in Ecuador, the USA, and 17 countries in Asia and Europe. 5-year survival for stomach cancer in 2005-09 was high (54-58%) in Japan and South Korea, compared with less than 40% in other countries. By contrast, 5-year survival from adult leukaemia in Japan and South Korea (18-23%) is lower than in most other countries. 5-year survival from childhood acute lymphoblastic leukaemia is less than 60% in several countries, but as high as 90% in Canada and four European countries, which suggests major deficiencies in the management of a largely curable disease. INTERPRETATION: International comparison of survival trends reveals very wide differences that are likely to be attributable to differences in access to early diagnosis and optimum treatment. Continuous worldwide surveillance of cancer survival should become an indispensable source of information for cancer patients and researchers and a stimulus for politicians to improve health policy and health-care systems.

Análisis de la influencia del Modelo Socioeconómico Chaebol en la crisis financiera del sudeste asiático de 1997: Tailandia

A partir del fin de la Guerra de Corea los diferentes gobiernos que tomaron el poder permitieron la consolidación de las grandes empresas Chaebol. El análisis social se basa en rescatar principios del confucianismo que pueden verse representados en el sistema corporativo estudiado, entre ellos la piedad filial, la honestidad, la educación. Al analizar los factores confucianos se logra determinar ciertas dinámicas presentes en las empresas Chaebol que muestran similitud con las causas de la Crisis Financiera del Sudeste asiático en 1997 lo que permite crear una relación entre el modelo y la crisis. La sobreinversión, el sobreendeudamiento, la relación entre el gobierno y los Chaebol son un ejemplo de dinámicas resultantes. Al tener a Tailandia como segundo país de referencia fue necesario buscar la existencia de relaciones entre el sistema económico y social tailandés, además de encontrar dinámicas resultantes del modelo corporativo de Tailandia similares a las coreanas para finalizar relacionándolas con la crisis financiera.

Place making in Hellenistic Athens: beyond decline and foreign patronage

The study of cities is integral to the study of the Hellenistic Age, the period bounded by the deaths of two legendary rulers: Alexander in 323 BC and Kleopatra in 30 BC. Modern scholarship has followed in the footsteps of Johann-Gustav Droysen, who coined the term 'Hellenistic' in the nineteenth century and associated it with the diffusion of Greek culture through the founding of new cities in the East by Alexander and his successors. Hellenistic Athens, traditionally discussed under the rubric of its Classical legacy and/or in contrast with thriving cities, such as Pergamon, has been presented as a backwater exemplifying the demise of the 'polis'. My objective in this paper is to criticise these negative sentiments by exploring how the built environment of Hellenistic Athens could potentially become an indicator of city vitality.

A new South American network to study the atmospheric electric field and its variations related to geophysical phenomena

In this paper we present the capability of a new network of field mill sensors to monitor the atmospheric electric field at various locations in South America; we also show some early results. The main objective of the new network is to obtain the characteristic Universal Time diurnal curve of the atmospheric electric field in fair weather, known as the Carnegie curve. The Carnegie curve is closely related to the current sources flowing in the Global Atmospheric Electric Circuit so that another goal is the study of this relationship on various time scales (transient/monthly/seasonal/annual). Also, by operating this new network, we may also study departures of the Carnegie curve from its long term average value related to various solar, geophysical and atmospheric phenomena such as the solar cycle, solar flares and energetic charged particles, galactic cosmic rays, seismic activity and specific meteorological events. We then expect to have a better understanding of the influence of these phenomena on the Global Atmospheric Electric Circuit and its time-varying behavior.
