To all HHH students going abroad: UMN travel policies - Global Notes

Please be aware that UMN requirements to purchase CISI insurance and seek permission for any country on the DOS travel warning list (and some that may be on other lists, like CDC) apply to all students on any university program abroad, or any overseas program connected to their studies at UMN, even if organized through another organization including internships, field experiences, capstones, study away, research or even a student-organized trip (if planned and promoted as UMN).

**MDP students going on field experiences and all students taking courses through Learning Abroad Center please note that the LAC handles CISI and release and waiver automatically for you.

2011 example: UMN had 3 students in Egypt spring 2011 semester. Two had UMN
CISI insurance and were quickly and efficiently repatriated from AU of Cairo via Madrid by the insurance company's security provider; a third student (unknown to UMN until he gave an interview to a media outlet) did not have insurance. He spent several days (3 days his family could not find him) in the Cairo airport, signed a promissory note to reimburse the US government for his evacuation flight to Istanbul ($2,000), and had to pay his costs in Istanbul as well as a new ticket home.

Travel Approval

The University of Minnesota encourages its students to participate in education experiences abroad. To minimize health and safety risks, University policy requires students, or faculty/staff leading students, traveling to countries on the US Department of State's travel warning list to seek special permission.

In addition, travelers may be required to submit a request for permission to travel to locations or participate in programs that pose a specific health, safety, or security concern as indicated by authorities other than the U.S. Department of State such as the Center for Disease Control (CDC), World Health Organization (WHO), non-U.S. government authorities (e.g., Australian or Canadian authorities), and University of Minnesota authorities.

The International Travel Risk Assessment and Advisory Committee will review
requests to travel to these countries. Applicants are encouraged to apply early. The committee review process commonly takes 6 to 8 weeks.

Please also note that even if students aren't going to a Travel Warning country, faculty/staff approving/sponsoring the travel are still required to assure students meet the policy requirements at: http://www.policy.umn.edu/Policies/Education/Student/EDABROAD_PROC02.html(insurance, release and waiver and emergency communication plan).

Please call or email me with any questions.

Cyberattack suspect to be sent home to Netherlands

MADRID (AP) ? A Dutch citizen arrested in Spain on suspicion of launching what authorities have called the biggest cyberattack in Internet history is expected to be handed over to the Netherlands within 10 days, a Spanish court official said Monday.

The suspect ? identified only by his initials S.K. ? was questioned Saturday in the National Court in Madrid after his arrest last week and agreed to the deal, according to the official, who spoke on condition of anonymity because court rules prevent him from giving his name.

Police say the 35-year-old suspect operated from a bunker in northeast Spain and also had a van capable of hacking into networks anywhere in the country. He was arrested Thursday in Granollers, 35 kilometers (22 miles) north of Barcelona.

He is accused of attacking the anti-spam watchdog group Spamhaus, whose main task is to halt ads for counterfeit Viagra and bogus weight-loss pills reaching the world's inboxes.

Dutch authorities alerted Spanish police in March of large denial-of-service attacks being launched from Spain that were affecting Internet servers in the Netherlands, United Kingdom and the U.S. These attacks culminated with a major onslaught on Spamhaus.

Denial-of-service attacks overwhelm a server with traffic, jamming it with incoming messages. Recent cyberattacks ? such as the ones that caused outages at U.S. banking sites last year ? have tended to peak at 100 billion bits per second. The attack on Spamhaus was three times that size.

Police from the Netherlands, Germany, Britain, Spain and the U.S. took part in the investigation.

Fireballs! 'Tis the season for massive meteors.

Tonight (April 23) through Friday at dawn may be your best chance of the year to spot a fireball, a meteor that shines brighter than Venus, the brightest planet in the sky.

By Joe Rao,?SPACE.com / April 23, 2013

In this picture provided by Wally Pacholka of AstroPics.com, a Geminid fireball explodes over the Mojave Desert in the Jojave Desert, Calif. on Dec. 13, 2009. Unlike this Geminid fireball, the fireball-watching in the next few nights isn't connected to the just-completed Lyriad meteor shower or any other regular meteor shower.

The dramatic fireball that exploded over Russia in February got many people wondering if there is any way to anticipate future dazzling meteors before they appear.

Well, meteors not associated with an annual shower are certainly tough to predict. But there are some patterns that skywatchers can keep in mind to maximize their chances of spotting a fireball (which technically is any meteor that shines more brightly than Venus in the sky).

For example, springtime is "fireball season," when the number of bright meteor sightings increases by as much as 30 percent, NASA experts say. And the three-day stretch from Tuesday (April 23) to Thursday (April 25) is perhaps the best time to watch for the next prospective fireball event, which might possibly even lead to the fall of a meteorite.?

Over the years, some real dazzlers have been seen during this time frame. And in at least two cases, the orbits of the meteors were virtually identical, suggesting Earth might hit more such space rocks when it passes through this part of its orbit.

A river of rubble?

Is there perhaps a "river of rubble" orbiting the sun that is populated by rather large meteoroids?

Unlike most of the annual meteor showers that are composed chiefly of dust and sand-sized particles ? such as the Lyrids, which peaked overnight Sunday (April 21) ? this supposed fireball stream might be made up of objects that are considerably larger, perhaps originating in the main asteroid belt between Mars and Jupiter or perhaps being shed by the nucleus of a long-dormant comet.?

The circumstantial evidence for such a meteor stream lies with two brilliant fireballs that appeared during the 1960s.

One of these fireballs cast shadows over northern New Jersey on April 23, 1962. The other was seen by thousands of people over England, Wales and Northern Ireland on April 25, 1969 and also dropped a 0.6-pound (0.27 kilograms) meteorite in the town of Sprucefield, Northern Ireland.

Daily Chronicle | Are lesbians more accepted than gay men?

CHICAGO ? It may be a man?s world, as the saying goes, but lesbians seem to have an easier time living in it than gay men do.

High-profile lesbian athletes have come out while still playing their sports, but not a single gay male athlete in major U.S. professional sports has done the same. While television?s most prominent same-sex parents are the two fictional dads on ?Modern Family,? surveys show that society is actually more comfortable with the idea of lesbians parenting children.

And then there is the ongoing debate over the Boy Scouts of America proposal to ease their ban on gay leaders and scouts.

Reaction to the proposal, which the BSA?s National Council will take up next month, has been swift and often harsh. Yet amid the discussions, the Girl Scouts of USA reiterated their policy prohibiting discrimination based on sexual orientation, among other things. That announcement has gone largely unnoticed.

Certainly, the difference in the public?s reaction to the scouting organizations can be attributed, in part, to their varied histories, including the Boy Scouts? longstanding religious ties and a base that has become less urban over the years, compared with the Girl Scouts?.

But there?s also an undercurrent here, one that?s often present in debates related to homosexuality, whether over the military?s now-defunct ?Don?t Ask, Don?t Tell? policy or even same-sex marriage. Even as society has become more accepting of homosexuality overall, longstanding research has shown more societal tolerance for lesbians than gay men, and that gay men are significantly more likely to be targets of violence.

That research also has found that it?s often straight men who have the most difficult time with homosexuality ? and particularly gay men ? says researcher Gregory Herek.

?Men are raised to think they have to prove their masculinity, and one big part about being masculine is being heterosexual. So we see that harassment, jokes, negative statements and violence are often ways that even younger men try to prove their heterosexuality,? says Herek, a psychologist at the University of California, Davis, who has, for years, studied this phenomenon and how it plays out in the gay community.

That is not, of course, to downplay the harassment lesbians face. It can be just as ugly.

But it?s not as frequent, Herek and others have found, especially in adulthood. It?s also not uncommon for lesbians to encounter straight men who have a fascination with them.

?The men hit on me. The women hit on me. But I never feel like I?m in any immediate danger,? says Sarah Toce, the 29-year-old editor of The Seattle Lesbian and managing editor of The Contributor, both online news magazines. ?If I were a gay man, I might ? and if it?s like this in Seattle, can you imagine what it is like in less-accepting parts of middle America??

One of Herek?s studies found that, overall, 38 percent of gay men said that, in adulthood, they?d been victims of vandalism, theft or violence ? hit, beaten or sexually assaulted ? because they were perceived as gay. About 13 percent of lesbians said the same.

A separate study of young people in England also found that, in their teens, gay boys and lesbians were almost twice as likely to be bullied as their straight peers. By young adulthood, it was about the same for lesbians and straight girls. But in this study, published recently in the journal Pediatrics, gay young men were almost four times more likely than their straight peers to be bullied.

At least one historian says it wasn?t always that way for either men or women, whose ?expressions of love? with friends of the same gender were seen as a norm ? even idealized ? in the 19th century.

?These relationships offered ample opportunity for those who would have wanted to act on it physically, even if most did not,? says Thomas Foster, associate professor and head of the history department at DePaul University in Chicago.

Today?s ?code of male gendered behavior,? he says, often rejects these kinds of expressions between men.

We joke about the ?bro-mance? ? a term used to describe close friendships between straight men. But in some sense, the humor stems from the insinuation that those relationships could be romantic, though everyone assumes they aren?t.

Call those friends ?gay,? a word that?s still commonly used as an insult, and that?s quite another thing. Consider the furor over Rutgers University men?s basketball coach Mike Rice, who was recently fired for mistreating his players and mocking them with gay slurs.

If two women dance together at a club or walk arm-in-arm down the street, people are usually less likely to question it ? though some wonder if that has more to do with a lack of awareness than acceptance.

?Lesbians are so invisible in our society. And so I think the hatred is more invisible,? says Laura Grimes, a licensed clinical social worker in Chicago whose counseling practice caters to gay, lesbian, bisexual and transgender clients.

Grimes says she also frequently hears from lesbians who are harassed for ?looking like dykes,? meaning that people are less accepting if they look more masculine.

Still, Ian O?Brien, a gay man in Washington, D.C., sees more room for women ?to transcend what femininity looks like, or at least negotiate that space a little bit more.?

O?Brien, who?s 23, recently wrote an opinion piece tied to the Boy Scout debate and his own experience in the Scouts when he was growing up in the San Diego area.

?To put it simply: Being a boy is supposed to look one way, and you get punished when it doesn?t,? O?Brien wrote in the piece, which appeared in The Advocate, a national magazine for the gay, lesbian, bisexual and transgender communities.

Joey Carrillo, a gay student at Elmhurst College in suburban Chicago, remembers trying to be as masculine as possible in high school. He hid the fact that he was gay, particularly around other athletes. As a wrestler, he says he never wanted to hear someone say, ?Oh, THAT?S why he wrestles.?

In fact, though more gay and lesbian athletes are coming out in college, gay male professional athletes in major sports have waited to do so until they have left their sport, one of the more recent being Robbie Rogers, an American soccer player who played professionally in England. There have been reports that gay male athletes who are currently playing may be on the verge of going public.

But women have already done so with little backlash.

U.S. soccer star Megan Rapinoe, for instance, came out right before she played in last year?s Olympics. WNBA star Seimone Augustus and the league?s No. 1 draft pick, Brittney Griner, are some of the more recent female athletes to follow suit.

In Hollywood in recent years, both openly gay men and lesbians have had successful careers. And when it comes to television and movies, it appears there are more high-profile gay male characters.

Still, while many see the two dads on the ?Modern Family? sitcom as groundbreaking, others have a sense that the societal discomfort with gay men as parents is at the root of many of the jokes.

?A good portion of that is for comedic effect,? says Don Todd, a 32-year-old father in a two-dad family in Orange, Calif. He doesn?t think most people would think it was as funny if the characters were two moms.

Herek, the researcher at UC-Davis, has, in fact, found in surveys that heterosexuals think lesbians would be better parents than gay men.

Nancy Dreyer, a mother in a two-mom family, has noticed this in her own life.

?With gay male friends of ours who have kids, people will say, ?My gosh, who takes care of this baby?? ? as if they?re not capable,? says Dreyer, whose 57 and lives in suburban Boston.

The assumption, she says, is that men aren?t nurturing. And if they?re too nurturing, she says, people get suspicious, noting that no one has ever questioned her and her partner about their ability to raise their son, who?s now in college.

She?s noticed the different ways society treats gay men and lesbians, partly because she has a brother, Benjamin Dreyer, who?s gay. The Dreyer siblings say it?s difficult to compare their experiences because Benjamin came out in college, and Nancy in her early 30s.

So he was the first to tell their parents. ?They yelled at me. They took you to dinner,? Benjamin Dreyer, who?s 54 and works in publishing in New York City, now jokes with his sister.

Truth was, as a young gay man coming of age as the AIDS epidemic took hold, his parents simply worried, and with good reason, his sister says.

There?s little doubt, they both say, that AIDS influenced the perception of gay men.

Benjamin Dreyer says he dealt with societal bias by avoiding it, and surrounding himself with people he knew would be supportive, including his parents, eventually.

But he?s also realizing how quickly the need to do that is disappearing. He was surprised and pleased, for instance, when he attended his nephew?s high school graduation last year. There, he saw a gay male graduate with his boyfriend, open and accepted by all his peers.

?It?s mind-boggling,? Benjamin Dreyer says. ?It?s wonderful.?

Carrillo, too, decided to live openly when he arrived at Elmhurst College. He joined a fraternity and even painted a rainbow ? a common symbol of the gay community ? on his fraternity paddle. To his surprise, there was some backlash from a couple of his straight fraternity brothers who feared people would think their fraternity was the ?gay fraternity.?

?There?s a long way to go,? says Carrillo, who graduates next month. But he still feels hopeful.

?Honestly, I see it ? everywhere there?s progress.?

Even Vinny Magalhaes can?t believe a judge gave him a round in UFC 159 loss to Phil Davis

At UFC 159 on Saturday night, Phil Davis showed off the best striking of his career. The NCAA Division-I champion wrestler clearly dominated Vinny Magalhaes in all three rounds on the way to a unanimous decision win. However, one of the judges thought Magalhaes won one round, and the score was 30-27, 30-27, 29-28.

It was a surprising score. It didn't take anything away from Davis' win, but it was odd enough that Magalhaes spoke up about it.

Davis and Magalhaes talked trash to each other for months before their bout. Magalhaes left the bad blood in the cage, and was able to give himself an honest assessment moments after the loss.

Mobile App Ratings: Teens Review Their Favorite Social Apps From ...

This article was written by teen reporters from The Mash, a weekly publication distributed to Chicagoland high schools.

By Ashley Black, St. Charles East high school, and Mikhaela Padilla, Whitney Young high school

The time of simple communication is dwindling toward extinction. Think about it: When?s the last time you called a friend from a landline phone and talked for hours? Year after year, study after study, it?s shown that teens favor communicating through social networks such as Facebook and Twitter.

But now, there?s a new crop of social networking applications that are readily available to teens (aka free)?and there?s something for everyone. Want to show off a vacation photo? Instagram is your best bet. Interested in documenting your life, one check-in at a time? Path can help you with that. Or maybe you just want to send a silly selfie to your best friends? Check out Snapchat.

We rounded up some of the most popular communication apps, tried them out for ourselves and gave them report cards.

Instagram

Instagram allows its users to play professional photographer with filters, a cropping tool and focus options. Plus, you can see what your friends (and celebs) are up to through live updates.

Unlike Facebook and Twitter, Instagram is a photo-only app that banks on creativity. ?People love it because it shows a little bit of your personality and your life,? said Brianna Booth, a freshman at Barrington.

Since Instagram?s launch in 2010, heaps of knockoff apps have debuted. Still, most lack the massive following that Instagram has built.

Instagram did come under fire late last year after changing its terms of service. Users worried that the app could sell their works of art. Instagram cleared that up: You own your photos, but Instagram can share your user data with its parent company, Facebook.

Grade: A
Top marks for: user-friendly tools, creativity and cult-like following
Could improve: confusing service terms

GifBoom

In a nutshell, GifBoom is a moving Instagram. The app makes it easy to create and share your very own gifs (aka animated photographs, like the ones on whatshouldwecallme.tumblr.com). Unlike Tumblr, GifBoom only allows its users to share gifs?no still photos allowed.

One major complaint? It?s not super user-friendly at first. ?It was hard to navigate for the first week,? said Gina Paletta, a freshman at St. Charles East. ?I had no idea what I was doing and it took time to figure out.?

Once you get the hang of it, GifBoom is a unique app to have. If you?ve ever wished your Instagram photos could move, this app is for you.

Grade: B+
Top marks for: growing user base and clean design
Could improve: ease of use and tools

Pheed

If Facebook, Twitter, Instagram and YouTube had a baby (don?t ask us how), it would be Pheed. The easy-to-use, clutter-free app is quickly gaining popularity and followers. You can use Pheed to share texts, photos, videos, audio and live broadcasts.

Some would say the concept is new, but others find it repetitive. ?Facebook is all I need because other apps are basically all just the same,? said Jose Garcia, a junior at Carl Schurz.

But there is something that sets Pheed apart: Users can subscribe to premium channels for a fee (anywhere from $1.99 to $34.99 per month). For example, a singer might broadcast their performance or concert on Pheed and users would have to subscribe?and possibly pay a fee?to view it.

Grade: A-
Top marks for: clutter-free design and ease of use
Could improve: originality and premium fees

Path

If you love the idea of Facebook?s timeline, Path might just be your new favorite app. The new-ish concept allows you to share almost anything: your current location, what you?re listening to, future plans, cute stickers and more. The app also allows you to have conversations with friends (as shown above).

?Facebook and Instagram are easier to use and understand, but Path is a more minute-by-minute timeline of someone?s day,? said Brooke Rinker, a senior at St. Charles East.

One major difference between Facebook and Path is that you can have only 150 friends on Path. It creates a more close-knit feeling for many users, but some find it too restrictive.

Grade: B
Top marks for: live updating and variety
Could improve: sharing restrictions and ease of use

Snapchat

Snapchat is like nothing else on the app market. You take a photo or short video, add text or a doodle and send it to your friends to view for a set amount of time (one to 10 seconds, your choice). Once your friends open the pic, they have to press down on their phone screen to view your photo. After the timer is up, the photo or video disappears forever ? or so we?re told.

?Snapchat allows people to easily share information about their lives on a whole (different) level using photos,? said Willie Stevan, a sophomore at Whitney Young. ?I send about 15 snaps a day and receive, like, 50!?

One downfall? The privacy settings are questionable. A University of Michigan student and hacker, Raj Vir, reported that users secretly can save incoming images. Note to all: Don?t send anything via Snapchat that you wouldn?t want to resurface.

Grade: B+
Top marks for: originality and easy-to-use tools
Could improve: privacy settings

Getting to the Bottom of Why Guppies Jump

When a guppy jumped out of a laboratory tank and nearly landed in her cup of tea, Daphne Soares couldn?t resist putting her current research on hold to investigate this strange leaping behavior.

"The guppy jumped from its holding tank next to my computer," Soares, an assistant professor in the department of biology at the University of Maryland in College Park, told LiveScience. "Why do they do this? It was one of those things that we were just too curious about, so we had to look into it."

Soares and her colleagues used high-speed cameras to film a group of nine male guppies from the island of Trinidad. Their research, published online April 16 in the journal PLOS ONE, suggests wild guppies use their curious jumping ability as a way to spread the species away from an original habitat, to a new place with fewer predators. In other words, jumping likely serves a crucial evolutionary function for guppies.

"It's like how dandelions spread their seeds all over ? original populations give rise to secondary populations," Soares explained. "When guppies jump, we think it has to do with this idea of biological dispersal, which refers to a species moving away from an existing population to try to colonize another patch of habitat." [10 Amazing Facts About Animals]

Guppies are known to be jumpy fish, but unlike other species (such as archer fish or sockeye salmon), they do not seem to leap out of the water to catch prey, escape from predators or overcome physical barriers during seasonal migrations.

"They just have this urge to jump," Soares said. "They don't do it out of panic, or because they're anxious about their environment. When we monitored them, they jumped when they were quiet and relaxed. Most fishes jump when they're startled, so either for migration or to avoid predators. But with guppies, it was a controlled situation when they performed this behavior."

In studying their high-speed video of leaping guppies, the researchers observed that the fish go through a short process to prepare for their jumps.

"I don't want to anthropomorphize too much, but it's almost like they have a plan," Soares said. "They stop, then use just their lateral fins to move a bit backwards, then they change direction, and when they take off from the water, they keep moving their bodies back and forth."

The scientists were also curious how far the fish could fling themselves out of the water. In some of their observed cases, guppies were able to launch themselves to heights eight times their body length, at speeds of more than 4 feet per second (1.2 meters per second).

The researchers used wild guppies for their study, so what triggers pet guppies to jump remains a bit of a mystery.

"Domesticated guppies probably maintain some of their ancestral behaviors, but I don't really know," Soares said.

And as for the guppy that nearly jumped into Soares' tea?

"Fortunately it was iced chai and it had a lid on, so he stayed alive," she said.
