SANTA FE, N.M. (AP) - Gov. Susana Martinez has appointed a Clovis attorney to a fill a vacancy on the Ninth Judicial District Court bench.

The appointment of Fred Van Soelen was announced Friday.

He fills the spot left by the retirement of Judge Teddy Hartley.

The governor's office says Van Soelen has practiced law for more than 14 years in New Mexico.

He was the Ninth Judicial Deputy District Attorney in Clovis before taking his current associate position at the Harmon Law Office.

While Van Soelen worked for the Ninth Judicial District, he was also an instructor at Clovis Community College.

From Egypt petition drive, a new grassroot wave

CAIRO (AP) ? Teenager Gehad Mustafa wears an ultraconservative veil over her face and was raised in a family of staunch Muslim Brotherhood supporters. Yet for the past weeks, she has been walking though chaotic street markets and crowded subway stations, collecting signatures on a petition demanding Islamist President Mohammed Morsi step down.

The months-long petition campaign by the group "Tamarod," Arabic for "rebel," is now culminating in nationwide protests Sunday in which the opposition hopes to bring out millions to force Morsi out of office, a year after his inauguration.

But Tamarod's organizers say they are not stopping there. No matter what happens on Sunday, they say they have created through their petition drive a real grassroots network, an opposition version in the spirit of the Islamists' expert street organizing, and have brought forth a sort of second generation of street activists, like Mustafa, after the first that led the revolt against autocrat Hosni Mubarak in 2011.

They want to use that network going ahead, to keep the public involved and to pressure the secular and liberal opposition parties, who the activists say have wasted opportunities through infighting and fragmentation, to get their act together.

On a recent day, Tamarod's main office, steps away from Cairo's Tahrir Square, was bustling with several dozen volunteers as young as 13 and as old as their 50s and 60s. University professors, government employees, students and housewives sipped tea, smoked and chatted while going through the organization's prize possession: the sheaves of signed petitions still coming in from around the country, filling the office.

The pages of signatures, they say, are proof of how deeply the country of 90 million has turned against the Muslim Brotherhood. They plan to announce their full count ahead of Sunday's protests but have claimed to have as many as 20 million signatures, which they collate, confirm and record in a database in a precise operation, knowing their count will be questioned.

Among the volunteers was 17-year-old Mustafa. She said she turned against Morsi and his Muslim Brotherhood after the first protesters were killed under his administration in late 2012. "I saw the reality," she said. "You told us that the blood of the martyrs will not go in vain. But there were more ... falling under your rule."

She joined Tamarod, which launched in late April, and volunteered to canvas the street for signatures. At one point, while passing out petitions in the subway, a man wearing the beard of a Muslim conservative attacked her, pulling the veil off her face. But other commuters then wrestled the man away in support of her.

"This strengthened me. I felt what I am doing is right," she said.

Organizers say Tamarod mushroomed across the country. Founded by five activists, its leadership is a central group of about 25, connected to a network of coordinators in Egypt's 27 provinces, each with a team of volunteers in towns and villages.

The signatures are effectively a database of the dissatisfied: Each signatory puts his or her name, province of residence and national ID number.

Collecting signatures in itself is a breakthrough, overcoming Egyptians' engrained resistance to signing onto any paper presented by a stranger, especially political, from the Mubarak days when doing so could get you a visit from state security or even arrested. Volunteers carrying the petitions brought politics into every corner ? weddings, slum alleys, buses and subways. Volunteers included strangers to political campaigning, from men selling cigarettes in kiosks to impoverished women selling in vegetable markets.

Ahmed el-Masry, one of the founders of Tamarod, calls the success "astonishing."

"I can't tell how many members out there. I can think that millions of Egyptians are members," he said.

"At one point, people gave up (on Morsi) ... it reached a point where a new class of Brothers are gaining higher status in society that to join them, you have to let your beard grow. We reached a point where no one is heard but the president and his tribe."

Brotherhood officials cast doubt on the signatures, claiming forgeries and multiple names. While Morsi says peaceful demonstrations are a legitimate form of expression, he and his allies also say Mubarak loyalists are behind the campaign and protests, trying to use the streets to topple an elected leader.

A spokesman for the Brotherhood's Freedom and Justice Party said he sympathizes with some activists in Tamarod ? "the young revolutionaries who had great expectations out of the revolution. Due to their inexperience and age, they wanted to see change too fast and too soon and that is what I call frustration."

But Abdel-Mawgoud el-Dardery said "opportunist politicians" are exploiting them for their political agenda and that former regime elements are exploiting both the politicians and the activists.

"There is unholy alliance among these groups. They have insisted on having one enemy and that is President Morsi," he said.

Tamarod activists say it is they who are leading the politicians of the mainly liberal and secular opposition parties and factions, trying to drag them into a better connection with the public. The campaign's plan calls for Morsi to leave, the chief justice of the Supreme Constitutional Court to become a largely symbolic interim president while a technocrat Cabinet governs, a panel would write a new constitution and presidential elections would be held in six months.

Ahmed Abdu, one of the first Tamarod street campaigners, said the group will pressure the opposition to coalesce behind a candidate.

If they can't get organized "we will pick one away from all the top leaders of opposition and we will be able to rally support to him."

He blamed liberal parties for running multiple candidates in last year's presidential election, which resulted in a runoff between Morsi and a former Mubarak prime minister, forcing people to choose between an Islamist and a loyalist of the regime just ousted.

"I hope they don't let us down again," Abdu said.

Tamarod's nationwide network and pavement-pounding methods contrast with many of the political parties, which have struggled to establish a nationwide presence. That is in large part what opened the way for the Muslim Brotherhood, an 83-year-old organization that has highly disciplined cadres nationwide, and harder-line Islamist with their own organizations to dominate parliament elections in late 2011-early 2012, to ensure the constitution passed a December referendum, and to boost Morsi to victory.

Tamarod's volunteers ? some former Morsi supporters, others who disliked him from the start ? had varying stories of what brought them to the campaign. Most said they were dismayed by what they call the Brotherhood's opportunism and determination to control the system rather than reform state institutions and police. That is a frequent refrain from critics of Morsi. His allies insist they are not trying to monopolize, that opponents have refused to work with them and that old regime loyalists have sabotaged their attempts at reform.

At the Tamarod office, Doaa Mohammed, a young Justice Ministry employee, said the day after Morsi's election, a man on the street spit at her face and yelled, "Tomorrow, Morsi will get rid of you all."

Mohammed wears a stylish scarf covering her hair, less strict than the more cloaking coverings and veils that hard-liners believe women should wear.

She said managers in her ministry were replaced by Brotherhood sympathizers.

"From day one, I have been treated like a second-class citizen. The Sister enjoys higher status than me just because she belongs to the group," she said, referring to the Muslim Sisters, the women's branch of the Brotherhood.

The heart of Tamarod is its petitions. Through Facebook and Twitter, volunteers could download the form, copy it and distribute them among friends and family members or hit the streets for signatures, then get back in touch with coordinators to return the papers.

At the Tamarod office, a psychology university lecturer-turned-volunteer explained how the papers are sorted by province, counted, scanned and entered into a database to ensure there are no doubled ID numbers and that the numbers ? which have prefixes by province ? match where they're said to come from. Much of the work takes place in a room labeled "Control Room. No Entry."

Secrecy is tight. The university lecturer spoke on condition of anonymity ? he goes by the nickname "Maestro" ? so he could not be singled out for pressure by anyone trying to get to the petitions. He said only two of the founders know the whereabouts of the originals of the signed forms and are responsible for moving them every few days to new locations.

"We are working in the daylight but they don't want us to work in the daylight," he said and added, "we are holding a pen and a paper. This is our weapon. And this is how we tell them, Enough"

FDA Gets Tough on Tobacco

As the Food and Drug Administration this week announced the rejection of four proposed tobacco products, experts voiced hope that the federal government can diminish tobacco use through regulation.

The FDA's decision Tuesday marked the first time tobacco products were subject to federal oversight. The FDA also authorized two new tobacco products though they are versions of what's already on the market.

The FDA's authorizations come four years after the passage of the Family Smoking Prevention and Tobacco Control Act, which gave the FDA the ability to regulate any new tobacco products put on the market.

"[The] historic announcement marks an important step toward the FDA's goal of reducing preventable disease and death caused by tobacco," FDA commissioner Dr. Margaret Hamburg said in a statement.

According to the Centers for Disease Control, tobacco smoke and secondhand smoke is responsible for the death of 443,000 Americans each year. Experts said the FDA's regulations were just one small step towards diminishing the use of tobacco in the U.S.

Dr. Richard Hurt, founder and director of the Mayo Clinic Nicotine Dependence Center in Minneapolis, said he was pleased the FDA had started to regulate products, although he remained concerned that it took the FDA four years to make a final decision about six products.

"This is just the toe in the water of the FDA's regulation," said Hurt. "All of us in the tobacco field have been waiting for them to do something."

Mitch Zeller, director of the FDA's Center for Tobacco Products, admitted that the process "has taken time," but believed it would become more streamlined in the future.

"As all involved parties continue to gain more experience, FDA expects the process to move much more quickly," Zeller told reporters during a call on Tuesday.

Some 4,000 tobacco products await FDA authorization. Approximately 3,500 of those products are already on the market because they beat a deadline that would have held them off the market pending FDA authorization. They are allowed to remain on the market unless the FDA issues an order saying they do not meet specific standards.

The products that were authorized were two different kinds of Newport non-menthol cigarettes from the Lorillard Tobacco Co. The FDA said they would be allowed on the market because they did not raise different public health questions than comparable products already on the market. By law, the FDA cannot name the four products that were rejected or their manufacturers.

The FDA said there could be a number of reasons new tobacco products do not get authorization, such as if they raise questions of public health, or if there was a lack of data on their impact on public health or incomplete test data.

The FDA's authorization did not mean the products were any healthier than other tobacco products. The FDA authorizes the products on the basis that they will not present more harm to the public health than a comparable product already on the market.

Though the two products passed FDA muster under the guidelines of the Family Smoking Prevention and Tobacco Control Act, that does not allow Lorillard to claim they have FDA approval, because they do not meet the criteria of being "safe and effective" for users.

Lorillard Tobacco CEO Murray Kessler said he was "pleased" with the FDA's ruling.

Tunisia frees feminist trio who staged topless protest against Islamist-led government

TUNIS, Tunisia -- A Tunisian court on Wednesday decided to release three European feminist activists who staged a topless protest in Tunis last month against the Islamist-led government.

The release of the three women -- one German and two French members the women's rights group, Femen -- could ease the anger of the European Union, Tunisia's main economic ally.

They were sentenced to four months in jail for indecency earlier this month after their May 29 protest to call for the release of fellow activist Tunisian Amina Tyler.

Tyler, 18, remains in custody, awaiting trial. She was arrested in Kairouan on May 19 after she hung a feminist banner from the wall of a mosque and tried to bare her breasts, on the same day that the Islamist Ansar al-Sharia group held a rally in the city that authorities tried to ban.

The decision to jail the three European women angered France, Germany and the European Union who urged the Islamist-led government to reform its laws on freedom of expression.

"The court sentenced these three activists to four months suspended jail terms... (the) women would leave Tunisia as soon as possible", one of their lawyers, Souhaib Bahri, told Reuters.

Police officers detain an activist from the feminist group Femen during a protest against the arrest of their Tunisian member Amina Tyler, in front of Tunisia's Ministry of Justice in Tunis May 29, 2013.

Witnesses said the women left the prison of Manouba late on Wednesday night.

Marguerite Stern and Pauline Hillier of France and Josephine Markmann of Germany apologized on Wednesday during their appeals hearing.

"I didn't think it was going to shock Tunisians to that extent. I would never do it again. We want to return to our country and our loved ones," Hillier said.

Femen has staged protests across Europe, mainly against Russia's detention of the all-female Pussy Riot punk band last year.

The new government is led by a moderate Islamist party, Ennahda, but hardline Islamist Salafists are seeking a broader role for religion, alarming a secular elite which fears this could undermine individual freedoms, women's rights and democracy.

Tunisia was the first country to be rocked by an "Arab Spring" uprising, inspiring similar revolutions in Egypt and Libya.

Secular groups say the Islamist-led government is trying to stifle freedom of expression and creativity, but the government strongly denies this.

Reputation Changer


The Internet has given a lot of power to the consumer?buyers of goods and services have many, many ways to sing a business's praises online or destroy its reputation. This has resulted in a new service industry called Online Reputation Management (ORM). Fortune 500 businesses and even celebrities are often clients of such services, but with one service called Reputation Changer, even small-to-mid-sized businesses can keep tabs on their online reputation. It's a very interesting service and, if your business has an online presence, it's worth a look.

How It Works
Reputation Changer is a cloud-based service that monitors any keywords you enter (such as your business name). The company also offers assistance in improving online reputation by manipulating search engines to push negative content about an individual or business further down in search results. The monitoring part is free.

?

Reputation Changer is not the biggest name in the ORM business. That is arguably, Reputation.com. However, Reputation.com does not offer a trial account for small to mid size businesses to test?not even the monitoring capabilities. With Reputation.com, you can sign up and cancel anytime, but to test the service out, you do have to sign up for it. The ability to test-drive reputation monitoring with Reputation Changer is a definite plus for small businesses.

You can create a free account at reputationchanger.com (it doesn't even require a credit card).You sign in the first time, and are asked to enter up to three keywords to search against. This creates a campaign.

Seeing as I'm not a business owner, I tested Reputation Changer by entering my first and last name. Once I did a dashboard displayed. This interface contains quite a bit of information and activity and the UI is aptly referred to as the "Command Center." This gives the user quite a bit of insight and information into their or their business's online reputation. The company tells me that the Command Center interface and tools are what set them apart from other ORM services.

Command Center
There are several different panels on the dashboard. In one, you are presented with a listing of any URLs to sites containing your keyword?the top-ranked URLs are displayed first. For example, at the top of the list was my PCMag bio information, likely the most searched or viewed URL containing my name.

There's a drop down list above this panel that allows you to switch the view to find URLs in the three major search engines: Google, Bing, and Yahoo.

The listed URLs are shown by their ranked position. Next to each, you can flag a URL as "negative" meaning it contains content on the site that can hurt a reputation. Now, Reputation Changer also has underlying algorithms that allow it to find and flag negative content for you. The service recognizes more than 100 negative domains and keywords that contain terms such as "fraud."

On the left panel from the URL listings, you can see how many negative listings a keyword tallies up. You can also here view how many times your keyword was searched. Two lower panels display related keywords and reputation alerts?these are notifications of any recent content on the Internet that contains your keywords.

I created another trial account (you can only have one campaign in the free account) and used a keyword containing a restaurant that had recently closed in my neighborhood, Manganaro's. The two abrasive sisters who ran the place were subject to a lot of criticism online. Sure enough, when I looked at the URL listings for this restaurant's name, there were several flagged as negative by Reputation Changer (a few links are to Yelp.)

Reputation alerts can also show postings in social media about your keyword. I asked a friend on Facebook to create a message tagging me and then delete it. Sure enough, I saw that person's post in Reputation Alerts, and I kept seeing it after it was deleted, days later. My concern about this feature is how up-to-date it is. You could be worrying about negative comments or posts online that no longer exist on a live server.

Reputation Monitoring
With a free account, you can also initiate active monitoring. By clicking "Reputation Monitoring" on the tabs at the top of the interface, you are given the option to add your keywords or a URL for monitoring. You can also send alerts to an email address.

One of the cleverest features is Auto Complete. You know when you type in words in Google and it will auto complete a search term? Well, Reputation Changer also monitors any auto-completed search terms associated with your keyword. Example: my keywords are my first and last name. Google auto complete shows my name auto-completing with "pc mag," "email," and "Linkedin." Reputation Changer automatically picked up on this and monitors these search terms.

The High Price of a Good Reputation
There is a lot to this service, more than I covered in this review. But, you may be asking, OK, so if I get negative reviews and see negative content on the Internet about me or my business how do I fix it? Well, monitoring is free. Fixing that negativity is not. For a fee, the company will provide ways to help bury negative content really deep down in searches. They do this in myriad ways: By creating reviews on sites Reputation Changer hosts, by posting favorable comments?essentially bombarding your keyword with positivity, and keeping the negativity down. That type of salvage will cost you, though.

This is how Reputation Changer makes money. To help an individual or business save face costs at least $5,000. Subscribing as a paid client also gives you more tools and features in the Command Center Additionally, without changing the problems that lead to the bad reviews in the first place, it's likely these sorts of review would crop up again.

Some may question the tactics of this type of service, I know I did. However, businesses (and people) are very vulnerable to attack from the open stage that is the Internet. It only takes one disgruntled customer, who is online-savvy, to really demean your business or service, and they may do so unfairly. Reputation Changer and other ORM services, give you a chance to be active in keeping intact a good reputation for your business, or yourself. It's a fascinating market and one of the first services we've reviewed in this space. I do think the free service offers much benefit to SMBs who want to track what the online community is saying about their business and for that, it gets four out of five stars for SMB services.

Solar power heads in a new direction: Thinner

June 26, 2013 ? Most efforts at improving solar cells have focused on increasing the efficiency of their energy conversion, or on lowering the cost of manufacturing. But now MIT researchers are opening another avenue for improvement, aiming to produce the thinnest and most lightweight solar panels possible.

Such panels, which have the potential to surpass any substance other than reactor-grade uranium in terms of energy produced per pound of material, could be made from stacked sheets of one-molecule-thick materials such as graphene or molybdenum disulfide.

Jeffrey Grossman, the Carl Richard Soderberg Associate Professor of Power Engineering at MIT, says the new approach "pushes towards the ultimate power conversion possible from a material" for solar power. Grossman is the senior author of a new paper describing this approach, published in the journal Nano Letters.

Although scientists have devoted considerable attention in recent years to the potential of two-dimensional materials such as graphene, Grossman says, there has been little study of their potential for solar applications. It turns out, he says, "they're not only OK, but it's amazing how well they do."

Using two layers of such atom-thick materials, Grossman says, his team has predicted solar cells with 1 to 2 percent efficiency in converting sunlight to electricity, That's low compared to the 15 to 20 percent efficiency of standard silicon solar cells, he says, but it's achieved using material that is thousands of times thinner and lighter than tissue paper. The two-layer solar cell is only 1 nanometer thick, while typical silicon solar cells can be hundreds of thousands of times that. The stacking of several of these two-dimensional layers could boost the efficiency significantly.

"Stacking a few layers could allow for higher efficiency, one that competes with other well-established solar cell technologies," says Marco Bernardi, a postdoc in MIT's Department of Materials Science who was the lead author of the paper. Maurizia Palummo, a senior researcher at the University of Rome visiting MIT through the MISTI Italy program, was also a co-author.

For applications where weight is a crucial factor -- such as in spacecraft, aviation or for use in remote areas of the developing world where transportation costs are significant -- such lightweight cells could already have great potential, Bernardi says.

Pound for pound, he says, the new solar cells produce up to 1,000 times more power than conventional photovoltaics. At about one nanometer (billionth of a meter) in thickness, "It's 20 to 50 times thinner than the thinnest solar cell that can be made today," Grossman adds. "You couldn't make a solar cell any thinner."

This slenderness is not only advantageous in shipping, but also in ease of mounting solar panels. About half the cost of today's panels is in support structures, installation, wiring and control systems, expenses that could be reduced through the use of lighter structures.

In addition, the material itself is much less expensive than the highly purified silicon used for standard solar cells -- and because the sheets are so thin, they require only minuscule amounts of the raw materials.

John Hart, an assistant professor of mechanical engineering, chemical engineering and art and design at the University of Michigan, says, "This is an exciting new approach to designing solar cells, and moreover an impressive example of how complementary nanostructured materials can be engineered to create new energy devices." Hart, who will be joining the MIT faculty this summer but had no involvement in this research, adds that, "I expect the mechanical flexibility and robustness of these thin layers would also be attractive."

The MIT team's work so far to demonstrate the potential of atom-thick materials for solar generation is "just the start," Grossman says. For one thing, molybdenum disulfide and molybdenum diselenide, the materials used in this work, are just two of many 2-D materials whose potential could be studied, to say nothing of different combinations of materials sandwiched together. "There's a whole zoo of these materials that can be explored," Grossman says. "My hope is that this work sets the stage for people to think about these materials in a new way."

While no large-scale methods of producing molybdenum disulfide and molybdenum diselenide exist at this point, this is an active area of research. Manufacturability is "an essential question," Grossman says, "but I think it's a solvable problem."

An additional advantage of such materials is their long-term stability, even in open air; other solar-cell materials must be protected under heavy and expensive layers of glass. "It's essentially stable in air, under ultraviolet light, and in moisture," Grossman says. "It's very robust."

The work so far has been based on computer modeling of the materials, Grossman says, adding that his group is now trying to produce such devices. "I think this is the tip of the iceberg in terms of utilizing 2-D materials for clean energy" he says.

This work was supported by the MIT Energy Initiative.
