Rethinking Social Security in Latin America

INTERNATIONAL SOCIAL SECURITY REVIEW, Issue 2-3 2005
Indermit Gill
In the past decade, many Latin American governments have radically restructured their old age income security systems, following the lead of Chile, which undertook its major pension reform in 1981. The defining characteristic of the reforms has been a shift in the basis of public pensions from social to individual responsibility: instead of the widely used system that "collectivized" or pooled the risk of being without the capacity to earn while aged, numerous countries in the region have adopted a system that relies on individual savings accounts. The reforms have maintained a role for a modified version of public pooling; this combination of individual and social savings to finance pensions is known as the "multipillar" approach. This article is based on a report prepared for the Office of the Chief Economist of the Latin America and Caribbean Region of the World Bank (Gill, Packard and Yermo, 2004).1 The report recognizes that the system of individual accounts, the essential aspect of the reform, has been a necessary and positive development, and one that is consistent with the economics of insurance and social welfare objectives. Beyond this recognition, however, the results of reform are much more complex. Each country has implemented its own version of the multipillar system. The article therefore draws on country evidence in order to determine: How has the new approach to public pensions in Latin America fared? In particular, have the changes left workers and their families in reform countries better off? The first section provides a brief description of the reforms. The second discusses the main macroeconomic concerns and effects. The third describes the impact on coverage levels, and other social welfare implications. The fourth evaluates the stagnation of coverage levels and presents various possible explanations. The fifth makes specific proposals to improve the multipillar pension system in Latin America. The last section concludes. [source]


Distribution of the genus Hypoplectrus (Teleostei: Serranidae) in the Greater Caribbean Region: support for a color-based speciation

MARINE ECOLOGY, Issue 2 2010
Alfonso Aguilar-Perera
Abstract The reef-associated fish genus Hypoplectrus (Serranidae), endemic to the western Atlantic Ocean, represents an ideal model to study speciation within a potentially highly dispersive (marine) ecosystem, because it consists of a complex of at least 10 morphs differentiated primarily by coloration. Although several recent studies on genetics, diet, and fertilization reveal little to no difference between the Hypoplectrus color morphs, there is still not a full understanding of what keeps these morphs distinct or drives their variation. Ecological information is needed alongside the genetic information to better understand this variation. Based on presence/absence records from scientific literature and direct observations in coral reefs, this work examined the distribution of the genus Hypoplectrus in the Greater Caribbean region. Some color morphs occurred simultaneously at given locations, but others showed geographic restrictions. Using cluster and nMDS analyses, we found three major groupings according to distribution: (i) widespread (Hypoplectrus puella, Hypoplectrus unicolor, and Hypoplectrus nigricans), (ii) less widespread (Hypoplectrus indigo, Hypoplectrus gummigutta, Hypoplectrus chlorurus, Hypoplectrus aberrans, and Hypoplectrus guttavarius), and (iii) geographically confined or segregated (Hypoplectrus gemma, Hypoplectrus providencianus). Geographic sections selected for the Greater Caribbean (eastern, western and northern) were dominated by at least three widely distributed Hypoplectrus morphs. New geographic records of some color morphs were documented and compared to previous established distribution ranges in the Greater Caribbean. [source]


RAPID SPECIATION AND ECOLOGICAL DIVERGENCE IN THE AMERICAN SEVEN-SPINED GOBIES (GOBIIDAE, GOBIOSOMATINI) INFERRED FROM A MOLECULAR PHYLOGENY

EVOLUTION, Issue 7 2003
Lukas Rüber
Abstract., The American seven-spined gobies (Gobiidae, Gobiosomatini) are highly diverse both in morphology and ecology with many endemics in the Caribbean region. We have reconstructed a molecular phylogeny of 54 Gobio-somatini taxa (65 individuals) based on a 1646-bp region that includes the mitochondrial 12S rRNA, tRNA-Val, and 16S rRNA genes. Our results support the monophyly of the seven-spined gobies and are in agreement with the existence of two major groups within the tribe, the Gobiosoma group and the Microgobius group. However, they reject the monophyly of some of the Gobiosomatini genera. We use the molecular phylogeny to study the dynamics of speciation in the Gobiosomatini by testing for departures from the constant speciation rate model. We observe a burst of speciation in the early evolutionary history of the group and a subsequent slowdown. Our results show a split among clades into coastal-estuarian, deep ocean, and tropical reef habitats. Major habitat shifts account for the early significant acceleration in lineage splitting and speciation rate and the initial divergence of the main Gobiosomatini clades. We found that subsequent diversification is triggered by behavior and niche specializations at least in the reef-associated clades. Overall, our results confirm that the diversity of Gobiosomatini has arisen during episodes of adaptive radiation, and emphasize the importance of ecology in marine speciation. [source]


Caribbean Children's Geographies: A Case Study of Jamaica

GEOGRAPHY COMPASS (ELECTRONIC), Issue 1 2007
Therese Ferguson
Understanding children's lives within the various spaces, places, and environments they inhabit is critical to making their worlds safer, facilitating their participatory roles in society, and implementing policies relevant to their realities. While the children's geographies scholarship is rapidly growing, much of the research is still centred on children in the ,West', with less focus on those in developing countries. Within the Third World, the Caribbean itself is slightly marginalised. This article uses the island-nation of Jamaica as a case study within the Caribbean region, examining some of the areas of interest in research on children's environments, and reflecting upon progress made in the range of methodological and theoretical approaches brought to the research agenda. It suggests prospective directions for future research to further a critical approach to this expanding field, both within Jamaica and the wider region. It ends by briefly raising some ethical issues for consideration, arising from advancing a research agenda with children at its fore. [source]

Comprehensive review of the records of the biota of the Indian Seas and introduction of non-indigenous species

AQUATIC CONSERVATION: MARINE AND FRESHWATER ECOSYSTEMS, Issue 2 2005
D.V. Subba Rao
Abstract 1.Comparison of the pre-1960 faunal survey data for the Indian Seas with that for the post-1960 period showed that 205 non-indigenous taxa were introduced in the post-1960 period; shipping activity is considered a plausible major vector for many of these introductions. 2.Of the non-indigenous taxa, 21% were fish, followed by Polychaeta (<11%), Algae (10%), Crustacea (10%), Mollusca (10%), Ciliata (8%), Fungi (7%), Ascidians (6%) and minor invertebrates (17%). 3.An analysis of the data suggests a correspondence between the shipping routes between India and various regions. There were 75 species common to the Indian Seas and the coastal seas of China and Japan, 63 to the Indo-Malaysian region, 42 to the Mediterranean, 40 and 34 to western and eastern Atlantic respectively, and 41 to Australia and New Zealand. A further 33 species were common to the Caribbean region, 32 to the eastern Pacific, 14 and 24 to the west and east coasts of Africa respectively, 18 to the Baltic, 15 to the middle Arabian Gulf and Red Sea, and 10 to the Brazilian coast. 4.The Indo-Malaysian region can be identified as a centre of xenodiversity for biota from Southeast Asia, China, Japan, Philippines and Australian regions. 5.Of the introduced species, the bivalve Mytilopsis sallei and the serpulid Ficopomatus enigmaticus have become pests in the Indian Seas, consistent with the Williamson and Fitter ,tens rule'. Included amongst the biota with economic impact are nine fouling and six wood-destroying organisms. 6.Novel occurrences of the human pathogenic vibrios, e.g. Vibrio parahaemolyticus, non-01 Vibrio cholerae, Vibrio vulnificus and Vibrio mimicus and the harmful algal bloom species Alexandrium spp. and Gymnodinium nagasakiense in the Indian coastal waters could be attributed to ballast water introductions. 7.Introductions of alien biota could pose a threat to the highly productive tropical coastal waters, estuaries and mariculture sites and could cause economic impacts and ecological surprises. 8.In addition to strict enforcement of a national quarantine policy on ballast water discharges, long-term multidisciplinary research on ballast water invaders is crucial to enhance our understanding of the biodiversity and functioning of the ecosystem.

Strategies for Establishing Organ Transplant Programs in Developing Countries: The Latin America and Caribbean Experience

ARTIFICIAL ORGANS, Issue 7 2006
José Osmar Medina-Pestana
Abstract:, The Latin America and Caribbean region is composed of 39 countries. It is remarkable the progress of transplantation in the region in despite of the low economic resources when compared to other regions. The criteria for brain death are well established and culturally accepted. The consent for retrieval is based on required family consent in most countries. The regulations for living donors are also well established, with restrictions to unrelated donors and prohibition of any kind of commerce. The access to transplant is limited by the model of public financing by each country, and those with public universal coverage have no financial restrictions to cover the costs for any citizen; in countries with restricted coverage, the access is restricted to the employment status. There is a progressive increment in the annual number of solid organ transplants in Latin America, reaching near 10 000 in 2004, accomplished by adequate legislation that is also concerned with the prohibition of organ commerce.

Inca, Sailor, Soldier, King: Gregor MacGregor and the Early Nineteenth-Century Caribbean

BULLETIN OF LATIN AMERICAN RESEARCH, Issue 1 2005
Matthew Brown
This article examines the recruiting practices, political propositions and changing identities of the Scottish adventurer Gregor MacGregor in the early nineteenth-century Caribbean. Based on original archival research and revision of the existing secondary literature, it seeks to understand why he has consistently been judged as a failure, and why neither Scotland nor any of the countries MacGregor worked in have wanted to claim him as their own hero. After an introduction providing biographical details and some historical context for the Caribbean in the period 1811,1830, the article looks in detail at what have been seen to be his successes and failures in the Caribbean region. It asks to what extent questions of ethnicity or masculinity have affected the way contemporaries and historians viewed MacGregor and his actions. In conclusion, it suggests that although he was a soldier and a sailor, and he was declared both an Inca and a King, his career was deemed a failure by both contemporaries and historians in Scotland, South America and the Caribbean. The main explanation for this negative assessment is that his ambitions continually fell foul of the interests of various Caribbean elites and of the distinctive historical circumstances of the region.1 [source]


Predictions of future climate change in the caribbean region using global general circulation models

INTERNATIONAL JOURNAL OF CLIMATOLOGY, Issue 5 2007
Moises E. Angeles
Abstract Since the 1800s the global average CO2 mixing ratio has increased and has been related to increases in surface air temperature (0.6 ± 0.2 °C) and variations in precipitation patterns among other weather and climatic variables. The Small Island Developing States (SIDS), according to the 2001 report of the Intergovernmental Panel on Climate Change (IPCC), are likely to be among the most seriously impacted regions on Earth by global climate changes. In this work, three climate change scenarios are investigated using the Parallel Climate Model (PCM) to study the impact of the global anthropogenic CO2 concentration increases on the Caribbean climate. A climatological analysis of the Caribbean seasonal climate variation was conducted employing the National Center for Environmental Prediction (NCEP) reanalysis data, the Xie,Arkin precipitation and the Reynolds,Smith Sea Surface Temperature (SST) observed data. The PCM is first evaluated to determine its ability to predict the present time Caribbean climatology. The PCM tends to under predict the SSTs, which along with the cold advection controls the rainfall variability. This seems to be a main source of bias considering the low model performance to predict rainfall activity over the Central and southern Caribbean. Future predictions indicate that feedback processes involving evolution of SST, cloud formation, and solar radiative interactions affect the rainfall annual variability simulated by PCM from 1996 to 2098. At the same time two large-scale indices, the Southern Oscillation Index (SOI) and the North Atlantic Oscillation (NAO) are strongly related with this rainfall annual variability. A future climatology from 2041 to 2058 is selected to observe the future Caribbean condition simulated by the PCM. It shows, during this climatology range, a future warming of approximately 1 °C (SSTs) along with an increase in the rain production during the Caribbean wet seasons (early and late rainfall seasons). Although the vertical wind shear is strengthened, it typically remains lower than 8 m/s, which along with SST > 26.5 °C provides favorable conditions for possible future increases in tropical storm frequency.
