MOSCOW (AP) ? A top Russian general says Moscow will secure a deal to extend Russian military presence in the Central Asian nation of Tajikistan by the first half of 2013.
Central Asian nations are apprehensive at the prospect of the NATO coalition?s withdrawal from Afghanistan in 2014 and have expressed fears that violence could spill over.
Russia?s ground forces commander Vladimir Chirkin said Saturday that outstanding issues on the terms of the deal will continue to be discussed with Tajikistan until the end of March.
Some 7,000 Russian soldiers are posted across three garrisons in the former Soviet republic neighboring Afghanistan.
An agreement to extend the current lease, which expires in 2014, has been delayed amid reported disagreements about the financial terms.

Of all the campaigns to undermine Haitian culture, the one to discredit restavek adoption ? in which a biological parent collaborates with a respected adult to care for a child ? enjoys the most zealous support from the west?s NGO and alternative press. This campaign reached fever pitch after Haiti?s Prime Minister called a moratorium on foreign adoptions in late January 2010 to prevent the removal of children from the country during the confusion that followed the January 12th earthquake.
Haitians unworthy of their children
Talking point: Haitian adoptive parents are, without exception, child abusers.
Reuters had this to say on February 2, 2010.
?Deeply ingrained in the culture of the impoverished former slave colony, the practice of poor families giving away children to wealthier acquaintances or relatives is known in the native Creole as ?restavek,? from the French words rester avec, or ?to stay with.?
?Critics call it slavery.
?The children, they said, are taken in as servants, forced to work without pay, isolated from other children in the household and seldom sent to school.?
The New York Times continued on February 25, 2010 with a video introduced by the caption.
?Even before the earthquake, one option for Port-au-Prince?s homeless children was Restavek, an underground system that some call foster care, and others call child slavery. Now their numbers swell.?
Note the deft language from Reuters and NYT to suggest that Haitians are child slavers without saying so outright:
?Critics call it slavery?/?others call child slavery.?
Meaning: We, of course, would never claim anything so outrageous.
By contrast, the alternative press? Council on Hemispheric Affairs expounded in July 2010:
?In the most impoverished country in the hemisphere, adults regularly view children as economic commodities, which make them highly vulnerable to the perils of trafficking.?
Beverly Bell, who directs several NGO and claims the defense of Haitian children as one of her main causes, wrote in a Huffington Post article titled: ?A Second Slave Rebellion in Haiti: What?s the Worth of a Haitian Child??:
?One of the many effects of poverty in Haiti is that desperate parents regularly give away their children in the hope that the new family will feed and educate the children better than they themselves can. Instead, the children usually end up as child slaves, or restavek. In a country which overthrew slavery in 1804, today anywhere from 225,000 to 300,000 children live in forced servitude. They work from before sunup to after sundown, are often sexually and physically abused, and usually go underfed and uneducated.?
The message is clear: it is desirable, even admirable, to snatch Haitian children from a culture of abuse in adoptive Haitian families.
Thus, as the Native-American and many other cultures were undermined by removing children from their families, today a project is underway to dismantle Haiti?s culture by shipping its youngest citizens, at a rate of 2,000 children per year, to foreign adoptions. This project is only possible because of a disinformation campaign that is most strident in the alternative press.

Haiti?s child abusers and traffickers
It would have been right and proper to mention, in any article during 2010 on the maltreatment of Haitian children, that Laura Silsby and nine other American Baptist missionaries were in jail in Haiti for attempting to traffic to the Dominican Republic 33 Haitian children, 22 of whom had at least one living parent. Simultaneously in the U.S., Catholic missionary Douglas Perlitz stood accused of the rape and psychological torture of 16 boys in a homeless shelter he had founded in Haiti.
Douglas Perlitz, a graduate of Fairfield University, Connecticut, talks on November 1, 2004 about his missionary work with Haitian street children. On December 21, 2010 he was sentenced to 20 years in prison for sex abuse (AP/The Connecticut Post/Jeff Bustraan).
?
The most shocking news came from Haitian Prime Minister Jean-Max Bellerive who publicly noted during an interview:
?There is organ trafficking for children and other persons also, because they need all types of organs.?
Such horrible abuse is possible because of a lack of follow up to Haiti?s international adoptions.
The same journalists who attacked Haitian adoption kept silent on these well-founded stories of child trafficking and abuse by westerners.

Real Restavek adoption
As one who is familiar with restavek adoption, I can recommend the following descriptions by anthropologists as being accurate. Here is what Katherine Dunham (in: Island Possessed, University of Chicago Press, 1969) wrote.
?In Haiti parents of the peasant class love their children. They also love the children of everyone else and expect everyone to love their children. There exists a whole naming practice for ?adopted? children among the people themselves ? Bienaimee, Dieudonne, Beinvenue, [Beloved, God-given, Welcomed-one] others representing affectionate regard. It is also remarkable in Haiti that there are not the roving bands of homeless young that one finds in other islands ? Jamaica and Puerto Rico for instance.?It is this care for the young that prompts parents when they are not able to feed all the children for whom they are responsible to seek homes for them. It seems best for all concerned to let one or more of the children out in semi-adoption to someone better placed?. The parent? would return to the country hoping for shoes, sufficient food and clothing, medical care, and eventually schooling for the child.?
Children board a bus headed for the airport in Port-au-Prince. Several children are being sent for adoption to France by the school Lycee Francais and the French Embassy in Haiti (AP/Julie Jacobson).
Here is a description by renowned anthropologist Melville J. Herskovits (in: Life in a Haitian Valley, Marcus Weiner Publishers, 1937):
?Quasi-adoption involves children, often of peasants?. To ?give? a person a child in this manner is in Mirebalais regarded as a token of friendship, and such children as were observed, though poorly clothed, were fed not much differently from the children of the families with which they were sent to live. When the ?ti moun? [child] grows older, he leaves and returns to his home?. Such a child repays the cost of keeping him by helping in the garden and by running errands.?
In my own family, where my mother served as a restavek and my aunt adopted a restavek, in each case a poorer woman placed a teenage girl with a woman of greater means (though not rich) whom she esteemed, and both women collaborated on the care and education of the child. The biological parent did not ?give away? her child but lived in the same city, maintained contact with the child and could withdraw her from the situation at any time.
Could western adoptions ever withstand such transparency and uncertainty?
Representations of restavek as being ?informal? or ?underground? are disingenuous. According to Haitian law, only partial adoptions that allow the biological parents contact with their children were recognized in Haiti before June 2012 (before the country became a signatory to the Hague Convention). In other words, all foreign full adoptions from Haiti were illegal before this Summer.
A Haitian child walks to a bus after arriving at a military airport in Eindhoven, Netherlands, along with 105 other children from Haiti, aged 6 months to 7 years, on Thursday Jan. 21, 2010, (AP/Peter Dejong).
Many poor Haitian children ? my own mother included ? have had their education, and their flight abroad to help wrest their families from poverty, sponsored by restavek adoption. By linking Haitian rich and poor, and those at home to those abroad in the care of children, this unconventional adoption system denies souls to the sweatshops and impedes neo-colonialism.

Top Democrats are defending Ambassador Susan Rice after a top House Republican called for her resignation because of questionable statements she made about the attack on the U.S. consulate in Benghazi, Libya.
Rice, the U.S. ambassador to the United Nations, has been hammered by Republican critics ever since she went on five interview shows on Sunday, Sept. 16 to say the attack on on the U.S. consulate was a "spontaneous" reaction to the outcry in Egypt over an anti-Muslim video posted on YouTube. Rep. Peter King, R-N.Y., the chairman of the House Homeland Security Committee, went so far as to say Rice should resign for intentionally misleading the American people about what really happened.
"I believe it was such a failure of foreign policy messaging and leadership, such a misstatement of facts as was known at the time," King said in an interview on CNN. "For her to go on all of those shows and, in effect, be our spokesman for the world and be misinforming the American people and our allies and countries around the world - somebody has to pay a price for this."
That prompted a quick response from Sen. John Kerry, D-Mass., the chairman of the Senate Foreign Relations Committee.
"I'm deeply disturbed by efforts to find the politics instead of finding the facts in this debate," Kerry said in a written statement. "I'm particularly troubled by calls for Ambassador Rice's resignation. She is a remarkable public servant for whom the liberation of the Libyan people has been a personal issue and a public mission. She's an enormously capable person who has represented us at the United Nations with strength and character."
In the days immediately following the attack in Benghazi, several other U.S. officials, including White House press secretary Jay Carney, also suggested it was spontaneous attack. But more recently, U.S. officials, including Defense Secretary Leon Panetta, have said the incident was a pre-planned terrorist attack.
In a statement Friday, Director of National Intelligence James Clapper called it a "deliberate and carefully planned terrorist attack" - although Clapper said U.S. intelligence agencies initially believed the attack was spontaneous and shared that information with the White House.
Rep. Steny Hoyer, D-Md., the second-highest-ranking Democrat in the House, also rallied to Rice's defense on Friday.
"Susan Rice is an exemplary public servant who has worked effectively on behalf of the U.S. and allies like Israel at the U.N.," Hoyer said in a written statement. "The loss of five Americans in Libya, including Ambassador Chris Stevens, is a horrible tragedy and we should be focused on bringing the perpetrators to justice, not playing politics. My understanding is that the information Ambassador Rice expressed reflected the intelligence community's most current assessment at that time."
In his statement, Kerry also pointed to an investigation ordered by Secretary of State Hillary Clinton into what happened in Benghazi.
"Everyone who cares about the five fallen Americans in Benghazi would do well to take a deep breath about what happened and allow Secretary Clinton's proactive, independent investigation to proceed," Kerry said. "Our committee in the Senate has unanimously asked that some highly detailed, highly specific questions be answered as part of the current investigation. Congress will have plenty of time to examine those answers, and to discern what happened in Benghazi once the investigation is fully underway and the facts become clear."
It's been a long time since we've seen any new blood refreshing Logitech's line of universal remotes, but after indications of new devices on the way in an earnings call earlier this year tipster Andrew spotted this brand new Harmony Touch on store shelves. Arriving at Best Buy unheralded by any official announcement or specs so far, the box shots and list of features show the ability to control 15 different devices and (of course) that center mounted touchscreen. There's no mention of it on the Logitech site either, however one leaked blog post we spotted referred to this device and a Harmony Plus.
As our friends at Tech of the Hub note, the Touch clearly draws a lot of its heritage from the Harmony One and 1100 touchscreen remotes although to have ditched the dedicated Activity button for "one touch" control. The touchscreen itself supports both taps and swipes as well as up to 50 customizable channel icons, and the box lists both online setup and on-remote customization as features. According to Andrew it's rocking a price tag of $249 -- $50 above the current price of the Harmony One but $100 shy of the RF-equipped Harmony 900 -- hopefully we'll find out soon if what Logitech has added this time around makes it worth the wait.
Update: Another one of our readers, Zachary also saw it at Best Buy and bought one, check out a few out of the box pics in the gallery below, and drop any questions about its capabilities in the comments. He's digging it so far, saying that the touchscreen is responsive and it found icons for his area quickly, with options to change background, LCD brightness and screen timeout. There does not appear to be any RF support however, so it's IR control only.
The Casio XJ-H2650 isn't Casio's brightest projector, but it's part of Casio's Pro Series, which is its brightest line of projectors. It also offers WXGA (1280 by 800) native resolution, the highest in the Pro Series line. That's a moderately big deal, because until now, if you wanted a WXGA Casio projector you had to settle for one of the lower brightness models. The XJ-H2650 delivers the highest brightness Casio offers with WXGA resolution, and the highest resolution with Pro Series brightness, all of which makes it a good choice for mid-size conference rooms and classrooms.
Casio rates the XJ-H2650 at 3500 lumens, a bit less bright than the 4,000 lumen Casio XJ-H1750 Pro Series that I reviewed earlier this year. However, the XJ-H1750 offers a native XGA (1,024 by 768) resolution.
The only other Pro Series model with WXGA resolution is the XJ-H2650's near twin, the Casio XJ-H2600 ($2,000 street). Casio says that the two models are identical except for the addition of USB A, USB B, and LAN ports to the XJ-H2650, along with features that depend on those ports. Most notably, the XJ-H2650's USB A port lets you plug in a supplied Wi-Fi adaptor so you can connect directly with, and send data images from, Windows and Mac computers as well as most Android, iOS, and Windows smartphones and tablets.
The extra ports also let you plug in a memory key to read JPG and a few other file formats directly, control the projector over a network, send data images over a network, and add interactivity with an interactive pen and software option ($260 street). However, the interactive feature is hard to recommend, since the projector's standard-throw lens would make it hard to interact with the image without casting shadows that would get in the way. All other features on the XJ-H2600 and XJ-H2650 should be identical, so the rest of the comments in this review should apply to both.
Basics, Setup, and Connections Like all current Casio projectors, the XJ-H2650 is built around Casio's hybrid light source, consisting of LEDs and a laser paired with a DLP chip. The LEDs produce the red and blue primaries directly. The laser shines on a phosphor element to produce green.
Not too surprisingly, given that both projectors are part of the same Pro Series, the XJ-H2650 shares a lot of its basic features with the XJ-H1750. In particular, it weighs almost the same, at 15.6 pounds, which makes it most appropriate for permanent installation or room to room portability on a cart.
Setup is standard, with a manual focus and a manual 1.2x zoom, which gives you some welcome flexibility in how far you can put the projector from the screen for a given size image. In addition to the LAN and USB ports I've already mentioned, connection choices include the usual HDMI for a computer or video source, VGA for computer or component video, and both S-video and composite video inputs.
Brightness and Eco Modes In my tests, the XJ-H2650 was easily bright enough in its brightest mode for a 78-inch wide (92-inch diagonal) image to stand up to the typical level of ambient light in an office or classroom setting. Even better, it was bright enough at that size so you could easily take advantage of its eco modes to minimize power use and save on electricity.
Most projectors offer one bright mode and one eco mode that lets you lower brightness and power consumption. Beyond that, they offer color presets that can also affect brightness, but are, in theory, meant to adjust color.
The XJ-H2650 gives you more flexibility for brightness and power use, with two non-eco modes, which I measured at 340 watts and 290 watts, plus five eco modes, with a measured range of 260 to 115 watts. With multiple eco modes, you have the freedom to pick the best color setting first, and then choose the least bright mode with the brightness you need, instead of using the color presets to adjust brightness. Also worth mention is that the only projector I've seen with more eco-mode levels is the laser-based BenQ LX60ST that I recently reviewed.
?The Cost of Crime,? a new study by David A. Anderson, Centre College?s Paul G. Blazer Professor of Economics, quantifies the burden of crime by estimating the annual cost of crime in the United States.
Danville, KY. (PRWEB) September 28, 2012
?The Cost of Crime,? a new study by David A. Anderson, Centre College?s Paul G. Blazer Professor of Economics, quantifies the burden of crime by estimating the annual cost of crime in the United States.
The study appears in Foundations and Trends in Microeconomics, Vol. 7: No 3.
Many studies measure crime by looking at raw numbers of thefts, murders and other criminal activities. Anderson warns that these numbers can be misleading, especially when the number of crimes goes in one direction while the severity of crimes goes in the other. For example, Anderson notes that ?a recent decrease in the number of thefts was accompanied by such a large increase in the average amount stolen that total victim losses actually increased.? Anderson says that scale issues make cost a better gauge of crime?s burden than counts of crimes.
Studies that do look at the cost of crime tend to focus on direct costs?dollars worth of stolen items, policing costs and the cost of the prison system. Yet Anderson finds that most of the costs of crime are indirect and include the opportunity cost of time, the costs of fear and agony, and private expenditures on crime prevention.
?When we consider the time and money spent locking things up, installing security systems, purchasing protective firearms, and providing medical care for victims,? Anderson says, ?the full cost of crime is revealed to be much larger.?
This is Anderson?s first study on the topic in 13 years. His 1999 study found the annual cost of crime in the United States to be $2.4 trillion (in 2012 dollars).
?The the annual cost of crime in the United States for one year is now about $3.2 trillion dollars, which is roughly the combined cost of the wars in Afghanistan and Iraq from 2001 to 2011,? Anderson says. ?We spend $2.7 trillion a year on health care. The burden of crime exceeds that by half a trillion dollars.?
Quantifying these enormous costs, Anderson says, provides a strong rationale for prioritizing activities that deter criminal activity, including increasing the presence of law enforcement officers and improving education efforts and social programs.

First observation of predator avoidance behavior by phytoplankton
NARRAGANSETT, R.I. September 28, 2012 Scientists at the University of Rhode Island's Graduate School of Oceanography have made the first observation of a predator avoidance behavior by a species of phytoplankton, a microscopic marine plant. Susanne Menden-Deuer, associate professor of oceanography, and doctoral student Elizabeth Harvey made the unexpected observation while studying the interactions between phytoplankton and zooplankton.
Their discovery will be published in the September 28 issue of the journal PLOS ONE.
"It has been well observed that phytoplankton can control their movements in the water and move toward light and nutrients," Menden-Deuer said. "What hasn't been known is that they respond to predators by swimming away from them. We don't know of any other plants that do this."
While imaging 3-dimensional predator-prey interactions, the researchers noted that the phytoplankton Heterosigma akashiwo swam differently in the presence of predators, and groups of them shifted their distribution away from the predators.
In a series of laboratory experiments, Menden-Deuer and Harvey found that the phytoplankton not only flee when in the presence of the predatory zooplankton, but they also flee when in water that had previously contained the predators. They found only a minimal effect when the phytoplankton were exposed to predators that do not feed on phytoplankton.
"The phytoplankton can clearly sense the predator is there. They flee even from the chemical scent of the predator but are most agitated when sensing a feeding predator," said Menden-Deuer.
When the scientists provided the phytoplankton with a refuge to avoid the predator an area of low salinity water that the predators cannot tolerate the phytoplankton moved to the refuge.
The important question these observations raise, according to Menden-Deuer, is how these interactions affect the survival of the prey species.
Measuring survival in the same experiments, the researchers found that fleeing helps the alga survive. Given a chance, the predators will eat all of the phytoplankton in one day if the algae have no safe place in which to escape, but they double every 48 hours if they have a refuge available to flee from predators. Fleeing makes the difference between life and death for this species, said Menden-Deuer.
"One of the puzzling things about some phytoplankton blooms is that they suddenly appear," she said. "Growth and nutrient availability don't always explain the formation of blooms. Our observation of algal fleeing from predators is another mechanism for how blooms could form. Amazingly, looking at individual microscopic behaviors can help to explain a macroscopic phenomenon."
The researchers say there is no way of knowing how common this behavior is or how many other species of phytoplankton also flee from predators, since this is the first observation of such a behavior.
"If it is common among phytoplankton, then it would be a very important process," Menden-Deuer said. "I wouldn't be surprised if other species had that capacity. It would be very beneficial to them."
In future studies, she hopes to observe these behaviors in the ocean and couple it with genetic investigations.

COLORADO SPRINGS, Colo. - At a rally Wednesday evening here in the Rocky Mountain State, Republican vice presidential nominee Paul Ryan sharpened his criticism of President Obama's leadership as commander-in-chief, telling this military-friendly crowd that the president's policies "project weakness abroad."
Obama proposals to cut defense spending, Ryan said, would scale back missile defense and directly cost Colorado almost 18,000 jobs.
"Of all the things that Mitt Romney and I differ, disagree with President Obama - we need a strong military!" Ryan said. "We believe in peace through strength. We believe that when America's military is strong, America is safer.
"These defense cuts that he is promising, these devastating defense cuts that he is promising not only undermine our peace, not only undermine our security, they compromise jobs right here," he said. "These devastating defense cuts will cut things like our missile defense. And you know what? It probably should come as no surprise, because when Barack Obama was running for office he said that he didn't believe in missile defense."
This goes back to Bob Woodward's recent book, "The Price of Politics," which explained that the $1.2 trillion sequester element of the deal to increase the debt limit in August 2011 was the White House's idea. Although members of both parties ultimately voted for the Budget Control Act, Republicans blame the president for coming up with it.
House Republicans voted twice to replace the defense sequester, while the Democratic Senate has not.
Ryan then recounted a candid moment President Obama shared with former Russian President Dmitry Medvedev during an open-mic moment at a summit in South Korea last March.
"This is my last election. After my election, I have more flexibility," Obama told Medvedev at the time.
That plea for space didn't sit well with Ryan.
"He was talking to the Russian president when he thought no one was listening. He said he needed more flexibility for after the election," Ryan said as the crowd booed. "Mitt Romney and I want to be very clear with you. We value and respect your mission here and we believe in and support missile defense and missile defense is necessary to keep us safe and we will not allow that to go through."
"Please know that when we gut our military as the president is proposing - when we equivocate on speaking up for our values overseas, our freedom, freedom of religion, freedom of speech, freedom for women and women's rights and individual rights - when we do this, we project weakness abroad," he said. "And when we project weakness abroad, our enemies are more willing to test us, they are more brazen and our allies are less willing to trust us and that will not happen under a Mitt Romney administration because we believe in peace through strength."
An international team of scientists, including geochemists from the University of California, Riverside, has uncovered new evidence linking extreme climate change, oxygen rise, and early animal evolution.
A dramatic rise in atmospheric oxygen levels has long been speculated as the trigger for early animal evolution. While the direct cause-and-effect relationships between animal and environmental evolution remain topics of intense debate, all this research has been hampered by the lack of direct evidence for an oxygen increase coincident with the appearance of the earliest animals ? until now.
In the Sept. 27 issue of the journal Nature, the research team, led by scientists at the University of Nevada, Las Vegas, offers the first evidence of a direct link between trends in early animal diversity and shifts in Earth system processes.
The fossil record shows a marked increase in animal and algae fossils roughly 635 million years ago. An analysis of organic-rich rocks from South China points to a sudden spike in oceanic oxygen levels at this time ? in the wake of severe glaciation. The new evidence pre-dates previous estimates of a life-sustaining oxygenation event by more than 50 million years.
"This work provides the first real evidence for a long speculated change in oxygen levels in the aftermath of the most severe climatic event in Earth's history ? one of the so-called 'Snowball Earth' glaciations," said Timothy Lyons, a professor of biogeochemistry at UC Riverside.
The research team analyzed concentrations of trace metals and sulfur isotopes, which are tracers of early oxygen levels, in mudstone collected from the Doushantuo Formation in South China. The team found spikes in concentrations of the trace metals, denoting higher oxygen levels in seawater on a global scale.
"We found levels of molybdenum and vanadium in the Doushantuo Formation mudstones that necessitate that the global ocean was well ventilated. This well-oxygenated ocean was the environmental backdrop for early animal diversification," said Noah Planavsky, a former UCR graduate student in Lyons's lab now at CalTech.
The high element concentrations found in the South China rocks are comparable to modern ocean sediments and point to a substantial oxygen increase in the ocean-atmosphere system around 635 million years ago. According to the researchers, the oxygen rise is likely due to increased organic carbon burial, a result of more nutrient availability following the extreme cold climate of the 'Snowball Earth' glaciation when ice shrouded much of Earth's surface.
Lyons and Planavsky argued in research published earlier in the journal Nature that a nutrient surplus associated with the extensive glaciations may have initiated intense carbon burial and oxygenation. Burial of organic carbon ? from photosynthetic organisms ? in ocean sediments would result in the release of vast amounts of oxygen into the ocean-atmosphere system.
"We are delighted that the new metal data from the South China shale seem to be confirming these hypothesized events," Lyons said.
The joint research was supported by grants from the National Science Foundation, the NASA Exobiology Program, and the National Natural Science Foundation of China. Besides Lyons and Planavsky, the research team includes Swapan K. Sahoo (first author of the research paper) and Ganqing Jiang (principal investigator of the study) of the University of Nevada, Las Vegas; Brian Kendall and Ariel D. Anbar of Arizona State University; Xinqiang Wang and Xiaoying Shi of the China University of Geosciences (Beijing); and UCR alumnus Clint Scott of United States Geological Survey.

MINNEAPOLIS (AP) - The New York Yankees have held third baseman Alex Rodriguez out of the lineup with a bruised left foot.
Rodriguez fouled a ball off his foot in Tuesday's game at Minnesota and was on the bench for Wednesday's series finale against the Twins. Manager Joe Girardi said he might've given Rodriguez a rest for this game regardless, or at least used him as the designated hitter. Girardi said the 14-time All-Star could be available to pinch hit depending on how he felt.
To break up the left-handers in his lineup, Girardi switched Derek Jeter to the second spot and made Ichiro Suzuki the leadoff man.
Rodriguez has one hit in his last 14 at-bats. He missed nearly six weeks earlier in the season because of a broken left hand.

Mailbag: The Braves closer has had the kind of utterly dominant season that should earn him some attention in the NL Cy Young race.
I have only recently started investing in the stock market thinking it was a pretty good time to since the stocks I liked were down. I went and bought them thinking that the market would come around and not panic and go back on course to fundamentals. With most of my picks getting hammered, like the FMD i bought at $39 and $35 now only $26, or TZOO I bought at $21 now only $15, should I sell and cut my losses? But I know that these are real good companies with strong businesses making me want to buy more of these stocks actually, unless they keep falling..
I?m a college student/entrepreneur from the Philippines looking to grow my moneyand thought of trying the stock market because I?ve read in so many books and articles that if I start now, I could take advantage of the power of compounding, so I did.:) Also being a lone investor here in Philippines, I don?t have anyone to consult with or ask advice from. And I?m not convinced enough yet to invest in local public companies. Thank you!
ASU to lead first-ever national algae testbed, awarded $15M grant from Department of Energy
The U.S. Department of Energy has selected the Arizona State University led Algae Testbed Public-Private Partnership (ATP3) for a $15M award for its Advancements in Sustainable Algal Production opportunity.
?This algae national testbed will provide high quality data and a network of sites that will speed the pace of innovation,? said Gary Dirks, director of ATP3 and ASU LightWorks, the university initiative that pulls light-inspired research at ASU under one strategic framework. ?The network will support companies and research institutions as they work to meet the nation?s energy challenges.?
"ASU is committed to advancing research and economic development," said Sethuraman Panchanathan, senior vice president with ASU's Office of Knowledge Enterprise Development. "We are proud of the work being done at the Arizona Center for Algae Technology and Innovation on our Polytechnic campus and are looking forward to increasing our impact on the advancement of the algae-industry in collaboration with the newly established ATP3 partnership."
The ATP3 partnership is led by the Arizona Center for Algae Technology and Innovation (AzCATI) housed at ASU?s Polytechnic campus with support from national labs and academic and industrial partners, including the National Renewable Energy Laboratory (NREL), Sandia National Laboratories, Cellana LLC, Touchstone Research Laboratory, SRS Energy, Cal Poly San Luis Obispo, Georgia Institute of Technology, University of Texas at Austin, and Commercial Algae Management.
?This is a critical step for DOE?s support of the growing algal biofuel industry,? said Philip Pienkos, principal manager of the applied biology group at NREL and director of integration for ATP3. ?The productivity data generated by the ATP3 testbeds will flow into techno-economic and lifecycle assessment models and provide a basis for tracking progress toward goals in production economics and sustainability. By making high quality testbed capabilities available to researchers and technology developers, they will allow rapid testing of novel concepts at scale and greatly accelerate commercialization.
"NREL is proud to play a key role in the establishment and operation of the ATP3 testbed in a manner that will allow DOE to achieve its long term goals towards production of advanced biofuels.?
ATP3 will function as a testing facility for the algal research community supporting the operation of existing outdoor algae cultivation systems and allowing researchers access to real-world conditions for algal biomass production for biofuel. Testbed facilities for the partnership are physically located in Arizona, Hawaii, California, Ohio and Georgia.
DOE?s investment from its Biomass Program in ATP3 means companies and research institutes will now have access to facilities and data from long-term algal cultivation trials for use in establishing a realistic and coherent state of technology for algal biofuels.
?This multi-regional testbed will address a major gap currently hindering the scale-up of algal biofuels,? said Blake Simmons, the biomass program manager for Sandia. ?This partnership will provide validated data on algal growth and biofuel production across multiple sites in the USA, and will provide essential data related to the scale-up and commercialization of algal biofuels.?
AzCATI was created by grants from Science Foundation Arizona and its president and CEO William Harris. AzCATI and algae research and development also benefitted from the strong support of Arizona Gov. Janice Brewer.
Two new algae-related bills passed in Arizona classify algae as agriculture and allow for growth and harvest of algae on state trust lands. These advancements in the state create a more attractive environment for industry. Arizona is poised to be a preferred destination for new algae-based companies to form and flourish.
