Are All Ethnic Backgrounds Compelling or Just Some?


by Janet Crain
Who is Hispanic? Since some have been saying that Sonia Sotomayor would not really be the first Hispanic on the SCOTUS, Judge Sotomayor and her supporters have begun leaning more toward describing her as a Latina woman. Because it surely cannot be claimed that Cordoza was that. :-) I have to admit that after reading the Freedictionary description below I was more confused than ever. Portugal is not considered Hispanic although all of South America is. And Brazil is Portuguese. My head is swimming. Add to that the genetic simularities of the people and it's even more confusing. Perhaps we should disregard all these labels and start looking at people and not assume having an ethnic background translates as a person who has suffered and is consequently more empathetic toward others. Perhaps that is also not true. I think some people who have suffered become bitter and mean as a snake. Others from privileged backgrounds are very compassionate.

Look at the person, not the background.


Cardozo was born in New York City, the son of Rebecca Washington (née Nathan) and Albert Jacob Cardozo.[1] Both Cardozo's maternal grandparents, Sara Seixas and Isaac Mendes Seixas Nathan, and his paternal grandparents, Ellen Hart and Michael H. Cardozo, were Sephardi Jews; their families immigrated from England before the American Revolution, and were descended from Jews who left the Iberian Peninsula for Holland during the Inquisition.[1] Cardozo family tradition held that their ancestors were Marranos from Portugal,[1] although Cardozo's ancestry has not been firmly traced to Portugal.[2]

Sotomayor is listed as a Sephardic Jewish name dating from the 1450s in Spain. It appears in many Sephardic name lists. In the Pre-Inquisition and for a century-plus after, the term "Portuguese" meant "Sephardic Jewish." In 1492, at the Expulsion, thousands of Jews went to Portugal where they thought they would be safe. Unfortunately, just a few years later, they again had to make the choice of convert to Catholicism under force or leave. In many cases, they were forced to convert through the forcible taking of their children. To Sephardim, there is no difference between Spanish and Portuguese.

The people of Puerto Rico represent a cultural and racial mix. When the Spanish forced the Taíno people into slavery, the entire indigenous population was virtually decimated, except for a few Amerindians who escaped into the remote mountains. Eventually they inter-married with the poor Spanish farmers and became known as jíbaros. Because of industrialization and migration to the cities, few jíbaros remain.

Besides the slaves imported from Africa (Sudan, Kongo, Senegal, Guinea, Sierra Leona, and the Gold, Ivory, and Grain coasts), other ethnic groups brought to work on the plantations joined the island's racial mix. Fleeing Simón Bolívar's independence movements in South America, Spanish loyalists fled to Puerto Rico - a fiercely conservative Spanish colony during the early 1800s. French families also flocked here from both Louisiana and Haiti. As changing governments or violent revolutions depressed the economies of Scotland and Ireland, many farmers from those countries also journeyed to Puerto Rico in search of a better life.

When the United States acquired the island in 1898, American influence was added to culture.

During the mid-19th century, labor was needed to build roads, initially, Chinese workers were imported for this task, followed by workers from such countries as Italy, France, Germany, and even Lebanon. American expatriates came to the island after 1898. Long after Spain had lost control of Puerto Rico, Spanish immigrants continued to arrive on the island. The most significant new immigrant population arrived in the 1960s, when thousands of Cubans fled from Fidel Castro's Communist state. The latest arrivals to Puerto Rico have come from the economically depressed Dominican Republic.

His·pan·ic (h-sp nik)
adj.
1. Of or relating to Spain or Spanish-speaking Latin America.
2. Of or relating to a Spanish-speaking people or culture.
n.
1. A Spanish-speaking person.
2. A U.S. citizen or resident of Latin-American or Spanish descent.

[Latin Hisp nicus, from Hisp nia, Spain.]

Usage Note: Though often used interchangeably in American English, Hispanic and Latino are not identical terms, and in certain contexts the choice between them can be significant. Hispanic, from the Latin word for "Spain," has the broader reference, potentially encompassing all Spanish-speaking peoples in both hemispheres and emphasizing the common denominator of language among communities that sometimes have little else in common. Latino which in Spanish means "Latin" but which as an English word is probably a shortening of the Spanish word latinoamericano refers more exclusively to persons or communities of Latin American origin. Of the two, only Hispanic can be used in referring to Spain and its history and culture; a native of Spain residing in the United States is a Hispanic, not a Latino, and one cannot substitute Latino in the phrase the Hispanic influence on native Mexican cultures without garbling the meaning. In practice, however, this distinction is of little significance when referring to residents of the United States, most of whom are of Latin American origin and can theoretically be called by either word.·A more important distinction concerns the sociopolitical rift that has opened between Latino and Hispanic in American usage. For a certain segment of the Spanish-speaking population, Latino is a term of ethnic pride and Hispanic a label that borders on the offensive. According to this view, Hispanic lacks the authenticity and cultural resonance of Latino, with its Spanish sound and its ability to show the feminine form Latina when used of women. Furthermore, Hispanic the term used by the U.S. Census Bureau and other government agencies is said to bear the stamp of an Anglo establishment far removed from the concerns of the Spanish-speaking community. While these views are strongly held by some, they are by no means universal, and the division in usage seems as related to geography as it is to politics, with Latino widely preferred in California and Hispanic the more usual term in Florida and Texas. Even in these regions, however, usage is often mixed, and it is not uncommon to find both terms used by the same writer or speaker. See Usage Note at Chicano.

Spanish Inquisition left genetic legacy in Iberia

It's not often that cultural and religious persecution makes countries more diverse, but the Spanish Inquisition might have done just that.

One in five Spaniards and Portuguese has a Jewish ancestor, while a tenth of Iberians boast North African ancestors, finds new research.

This melting pot probably occurred after centuries of coexistence and tolerance among Muslims, Jews and Christians ended in 1492, when Catholic monarchs converted or expelled the Islamic population, called Moriscos. Sephardic Jews, whose Iberian roots extend to the first century AD, received much the same treatment.

What We Don't Know Could Hurt Us......

by Janet Crain
Many will be surprised to learn that 61% of the microbes that cause disease in humans are transmitted to homo sapiens by animals. Almost every disease came from animals in the first place. Pre-agricultural societies had no epidemics or pandemics. Once these diseases became common in Europe, Asia and Africa and were spread by trading and increasingly efficient shipping methods, carriers would unwittingly expose newly contacted populations to deadly infections to which they had no immunity. Some 90% of the indigenous peoples of the Americas were reportedly wiped out in this manner.

But all this took years, many years. And now it could take days. Newly evolved mibrobes could infect hordes of people with no immunity.

From Newsweek

The jackpot events in influenza evolution occur when two different types of flu viruses happen to get into an animal cell at the same time, swapping entire chromosomes to create "reassorted" viruses.

We have a new virus in the world. It is still evolving and its ultimate trajectory cannot be seen right now.

Around Thanksgiving 2005 a teenage boy helped his brother-in-law butcher 31 pigs at a local Wisconsin slaughterhouse, and a week later the 17-year-old pinned down another pig while it was gutted. In the lead-up to the holidays the boy's family bought a chicken and kept the animal in their home, out of the harsh Sheboygan autumn. On Dec. 7, the teenager came down with the flu, suffering an illness that lasted three days. He visited a local clinic, then fully recovered, and nobody else in his family took ill.
This incident would hardly seem worth mentioning except that the influenza virus that infected the Wisconsin lad was unlike any previously seen. It appeared to be a mosaic of a wild-bird form of flu, a human type and a strain found in pigs.

It was an H1N1 swine influenza. Largely ignored at the time, the Wisconsin virus was a step along the evolutionary tree, leading to a virus that four years later would stun the world.

Flash-forward to April 2009, and young Édgar Enrique Hernández in faraway La Gloria, Mexico, suffers a bout of flu, found to be caused by a similar mosaic of swine/bird/human flu, also H1N1. And thousands of miles away in Cairo, the Egyptian government decides pigs are the source of disease, and orders 300,000 animals in the predominantly Muslim (therefore not pork-consuming) society slaughtered.

Each of these three incidents is related to the unfolding influenza crisis. It is the manner of human beings to seek blame during times of fear. Fingers are now pointing, either at the entire pig species Sus domestica, or at the nation of Mexico. Such exercises in blame are not only scientifically ill founded, ut are likely to prompt government actions that, at the very least, are useless and, at worst, harmful for efforts to control a pandemic.

We live in a globalized world, filled with shared microbial threats that arise in one place, are amplified somewhere else through human activities that aid and abet the germs, and then traverse vast geographic terrains in days, even hours—again, thanks to human activities and movements. If there is blame to be meted out, it should be directed at the species Homo sapiens and the manifest ways in which we are reshaping the world ecology, offering germs like the influenza virus extraordinary new opportunities to evolve, mutate and spread.

Back in 2005, the Wisconsin Division of Public Health hunted for sick pigs in Sheboygan County, but the animals the teenager had helped slaughter came from multiple farms across the area, and every farmer claimed his herd was healthy. The Wisconsin authorities forwarded blood samples from the infected teenager and his family to the Centers for Disease Control and Prevention in Atlanta. The CDC scientists discovered that the H1N1 virus had pieces of its RNA genetic material that matched a human flu first seen in New Caledonia in 1999, two swine types that had been circulating in Asia and Wisconsin for several years and an unknown avian-flu virus.

In 2006 the American Association of Swine Veterinarians reported that humans were passing their H1N1 viruses to pigs, causing widespread illness in swine herds, especially in the American Midwest. A year later at a county fair in Ohio an outbreak occurred, sickening many of the pigs, but not their human handlers. The cause was a type of H1N1 that was a close match to the Wisconsin strain, and may have been spread from human to pig.

Last year researchers from Iowa State University in Ames warned that pigs located in industrial-scale farms were being subjected to influenza infections from farm poultry, wild birds and their human handlers. Writing in The Journal of Infectious Diseases, Eileen Thacker and Bruce Janke said, "As a result of the constantly changing genetic makeup of individual influenza viruses in pigs, the U.S. swine industry is continually scrambling to respond to the influenza viruses circulating within individual production systems."

Something was changing. Pigs notoriously eat just about anything thrown their way, and rub up against each other frequently, readily passing infections within herds. Their stomachs are remarkably tolerant environs for microbes, which since ancient times have caused illness in humans who dined on raw or undercooked pork. Investigation of the 1918 influenza pandemic, which is now estimated to have killed up to 100 million people worldwide in 18 months, revealed that the viral culprit was a type H1N1 human flu that had infected pigs, and then circulated back to humans.

At the viral level, influenza is an awfully sloppy microbe that is in a constant state of mutation and evolution. Its genetic material is in the form of RNA (not DNA, as in humans), loosely collected into chromosomes. When a virus infects a cell, its chromosomes essentially fall apart into a mess, which is copied to make more viruses that then enter the bloodstream to spread throughout the body. Along the way in this copying process any other genetic material that may be lying about the cell is also stuffed into the thousands of viral copies that are made. If the virus happens to be reproducing this way inside a human cell, it picks up Homo sapiensgenetic material; from a chicken cell it absorbs avian genes; and from a pig cell it garners swine RNA. The jackpot events in influenza evolution occur when two different types of flu viruses happen to get into an animal cell at the same time, swapping entire chromosomes to create "reassorted" viruses.

Scientists prepare for a more severe strain of influenza that spreads as easily as the swine flu but is as lethal as SARS.

Uncle Sam Wants You(r) DNA





F.B.I. and States Vastly Expand DNA Databases
Published: April 18, 2009

Law enforcement officials are vastly expanding their collection of DNA to include millions more people who have been arrested or detained but not yet convicted. The move, intended to help solve more crimes, is raising concerns about the privacy of petty offenders and people who are presumed innocent.

More Profiles in the DNA Database

Until now, the federal government genetically tracked only convicts. But starting this month, the Federal Bureau of Investigation will join 15 states that collect DNA samples from those awaiting trial and will collect DNA from detained immigrants — the vanguard of a growing class of genetic registrants.

The F.B.I., with a DNA database of 6.7 million profiles, expects to accelerate its growth rate from 80,000 new entries a year to 1.2 million by 2012 — a 17-fold increase. F.B.I. officials say they expect DNA processing backlogs — which now stand at more than 500,000 cases — to increase.

Law enforcement officials say that expanding the DNA databanks to include legally innocent people will help solve more violent crimes. They point out that DNA has helped convict thousands of criminals and has exonerated more than 200 wrongfully convicted people.

But criminal justice experts cite Fourth Amendment privacy concerns and worry that the nation is becoming a genetic surveillance society.

Unhallowed Ground

http://www.newsweek.com/id/177724


This is a fascinating article about the painstaking DNA identification of the terrorists' remains and how they have been separated, when possible, from the victims of 9/11. The article addresses as well the question of where to put these remains. It's the first article worth reading that Newsweek has run in months.


But why now? Why did they wait? Because there was no way they wanted the American public to be reminded of that horrible day before the Election. Because maybe, just maybe, some would have come to their senses and changed their vote?
