Dark Side of the Force - Crowdsourcing

Crowdsourcing can be beautiful. In fact, it's got a touch of classic fantasy sci-fi charm about it. I'm thinking Alderon, before the Death Star (back in the first Star Wars release) blew up the entire planet.

Massive numbers of photos need the human touch.  A volunteer army of citizen scientists peruse these images working to differentiate cancer cells from normal blood and tissue cells. Can't you just see the people of that one-time tiny peaceful planet making similar contributions to those that are being made today in our own world?

Crowdsourcers contribute vital genetic information to Alzheimer research by contributing their own memory and attention test data. Other folks share information that is pooled in a database used by breast and ovarian cancer research. This isn't fantasy. It's reality.

Thousands of volunteers scour detailed satellite photos of the Indian Ocean, helping hugely in the effort to find a missing Malaysian Airlines jet. Crowdsourcing helps rescue workers to both avoid less likely search zones, as well as target areas where they are more likely to be successful. It's not just in movies when people come together in response to the suffering of others.

Other folks are involved in massive translation efforts. The goal of Duolingo is to “… get millions of people worldwide to translate the Internet.” (*). C-3PO himself, couldn't have done better.

People in Santa Cruz – ten percent of the population in fact – pooled their ideas and abilities to eliminate a $9.2 million shortfall for their city. The plans these people made continue raise money for the city and benefit local programs. Several other cities, both large and small, follow these same successful citizen government crowdsourcing patterns. Government of the people isn't a leftover from old time films.

Crowdsourcing sounds like a wonderful dream come true. We’re harnessing the good energy of thousands or even millions of people to create a righteous universe. It's something Star Warrior heroes like Luke Skywalker and Princess Leia would totally get behind. We are talking the power of The Force here!


So what’s not to like about crowdsourcing?

How about the ability to send work offshore to be completed by desperate people earning a dollar or even pennies an hour? The author of the “Digital Sweatshop” Wikipedia page says “…digital sweatshops represent a phenomenon in a recent trend that offers workers and the employers the freedom to accept and request services. However, some believe that completing repetitive tasks for very small amount of money is an act of exploitation, hence the term sweatshop. A notable example is the Amazon Mechanical Turk, a marketplace dedicated to crowdsourcing.”

With Mechanical Turk, amazon has access to an unlimited labor pool that will almost literally work for peanuts, doing basic tasks a machine can’t do, but that doesn’t require skilled human labor. And amazon isn’t the only player in this outsourcing field. Crowdsourcing of cheaply paid labor, has become a huge part of the digital economy. 

Who’s doing the work? Desperate people who’ll do whatever is required to survive. And yes, the potential for slave labor and child labor is there as well. Oh of course it isn’t only these folks. Skilled digital laborers in a number of third world countries are just as determined to make money. It’s not too hard to figure out that a lot of our software development, and tech support have been driven off shore. 

I can hear some funny breathing headed down the hall. Darth Vadar is on the loose. This kind of energy harnessing isn’t drawing Earth’s citizens into a collective sense of accomplishment. Nor is it a righteous universe we’re building here. It’s more like we’re headed straight into a real life sci-fi fantasy world, complete with an evil emperor.  

Do previously well-paid western workers plan to go to battle with their determined competitors in other countries? We all 
need to make a buck, a rupee or a yen. It’s a matter of coming together and figuring out how to we can all earn a decent living. 

Sounds like we need to get busy on some citizen-of-the-world crowdsourcing techniques to kick Lord Vadar and the dark side of The Force right back into fantasy land.

Yerba Santa: Just What the Doctor Ordered? (Hiking Edgewood)

Yerba Santa, the Holy Herb, is once more in bloom,
 at the Edgewood Preserve. 

On the last two docent hikes I led, a lot of folks have been asking my questions about how Yerba Santa was used historically. The following is extracted from a report that I wrote for a CA native plant class. 

Yerba Santa has long been used in traditional medicines by people in California. This information, however, is for interest only. I have no idea if any medical research supports using Yerba Santa in any of this ways, or if the plant is safe to chew, swallow, or apply to your skin.



What do you call it? Well for starters, It's a Hydropyllaceae, a.k.a. That's the Waterleaf family to those in the know.

The plant itself may be called... Eriodictyon californicum Yerba Santa, Mountain balm, Palo Santo, Holy Plant , or Holy Herb . “Yerba Santa” translates from Spanish into English as “Holy Herb’. 

Yerba Santa has been used locally as a medicine, both by pre-contact (native) peoples, and the Spaniards who came after 1769.

It’s scientific name Eriodic'tyon comes from the Greek erion, "wool," and diktuon, "net", because the undersides of some of the leaves have a fuzzy look. The species name simply means it’s found in California.

Physical Description
This plant is an evergreen shrub that grows to about waist height at Edgewood, though it can grow to be 3 meters tall. When Edgewood Yerba Santa begins blooming, preserve visitors on my docent walks take quite an interest in it. They ask me, "Why is it all black like that?". The black part they're asking about is leaves have a faint odor and  are typically infected with a black fungus, Heterosporium. The virus is not thought to hurt the plant, but it makes the leaves look ugly. 

Preferred Habitat
Yerba Santa is a typical chaparral plant. It grows profusely in this preserve on serpentine soil, in colonies that grow from shoots of shared underground roots.

Animal Uses including Human
Butterflies find the nectar of Yerba Santa very attractive.

“Yerba Santa was highly valued by many California tribes including the Salinan, Ohlone, Miwok, Pomo, and Yokuts who continue to use it for various medicinal purposes. The Spanish who came to early California were so impressed with the plant that they gave it the name Yerba Santa, meaning holy plant. Yerba Santa was introduced to the Spanish Padres 
at Mission San Antonio de Padua by the Salinan tribe and it became one of three major medicinal herbs used at the mission. The plants can be harvested at any stage, but are best in the fall when the leaves are sticky and aromatic. 

The Kashaya Pomo recommend gathering the leaves just before the plant begins to produce flowers. The leaves, stems and flowers are used . They are either eaten or made into a tea, decoction, or poultice. The flowers and the bitter, aromatic leaves may be used fresh or dried. The leaves and flowers were made into a “bitter or sweetish-soapy” tasting tea that was drunk to relieve headaches and other symptoms of tuberculosis. 

Infusions of Yerba Santa  leaves and flowers were used to treat fevers, coughs, colds, stomachaches asthma, rheumatism pleurisy, and to purify the blood. The Kawaiisu drank Yerba Santa tea instead of water for a month to treat gonorrhea. The Salinan used an infusion of the leaves as a balm for the eyes. Later, those at the San Antonio mission made eye balm by placing the leaves in corked glass bottles and allowing them to sweat in the sun.

Leaves were smoked or chewed to relieve asthma, coughs, colds, headaches, and stomachaches. Heated leaves were placed on the forehead to relieve headaches and other aches and sores. The sticky leaves conveniently stay in place upon the skin. Mashed leaves were applied externally to sores, cuts, wounds, and aching muscles. Mashed leaves were also used to reduce the swelling and relieve pain caused by bone  fractures . Yerba Santa, used alone or combined with other herbs, was applied to infected 
sores on humans and animals. The branches and leaves were burned in steam baths to treat rheumatism. 

Other Uses
The Ohlone wove the leaves into skirts and aprons. I wonder if they included those pretty purple flowers into the designs :-)

Wildlife: Bees visit the flowers of Yerba Santa, which make a deliciously spicy amber honey. Seedlings and young plants are relatively nutritious and palatable but the bitter compounds in mature Yerba Santa shrubs discourage most large herbivores. However it is an important forage crop for black- tailed deer in the winter when other food sources are unavailable. Birds and small mammals eat the seed capsules.

Livestock: Goats will sometimes eat the leaves and stems. Cattle will avoid Yerba Santa in favor of more palatable plants, which can be a problem in highly grazed areas where it can become the dominant plant. Because of it's nature preserve status there are no longer livestock here, but the Spanish certainly grazed cattle in local meadows.

Yerba Santa can be used for rehabilitating and stabilizing disturbed areas. The seeds germinate readily in disturbed soils. The shallow, spreading root system can help to stabilize areas subject to erosion caused by runoff.
