Masters of the Universe value one piece of jewelry above all else — a watch.

They're collectible, gorgeous, and, at times, incredibly expensive pieces that can be handed down from generation to generation.

Exactly the type of thing a titan of any industry would want.

We've put together a list and commentary about the wristwatches worn by some of Wall Street's most public executives. 

As expected, a couple of the watches are flashy. A few of them are really, really cheap by Wall Street standards. And one prominent banker doesn't even wear a watch. Ever. 

(If you know of the type of timepiece that an executive at your firm wears, feel free to send the tip to jlaroche@businessinsider.com)

Warren Buffett, Berkshire Hathaway

Buffett, the "Oracle of Omaha," wears a gold Rolex Day-Date. 

T. Boone Pickens, BP Capital

Oil magnate T. Boone Pickens also wears a yellow gold Rolex Day-Date that he purchased in 1964. 

Lloyd Blankfein, Goldman Sachs CEO

Goldman Sachs CEO Lloyd Blankfein rocks a Swatch with what appears to be a clear plastic band. Swatch's tend to range between $50 to $245. It's also not exactly the sort of timepiece you'd expect a chief executive of a Wall Street investment bank to wear. Then again, Goldman is "the most hipster" bank on Wall Street.  

While some people thrive on drama and conflict, others run the other way.

If you're in the latter category, you're in luck: There are plenty of high-paying jobs where conflict resolution and negotiation are rarely needed. 

We combed through the Occupational Information Network (O*NET), a US Department of Labor database that compile detailed information on hundreds of jobs, and looked at salary data on the US Bureau of Labor Statistics website to find positions with a median annual salary over $65,000 that don't require a lot of conflict resolution.

O*NET ranks how important "resolving conflicts and negotiating with others" is an any job, assigning each a "conflict resolution importance level" between 1 and 100. Negotiation-heavy positions, such as lawyers and social workers, rank between 90 and 100, while jobs such as engineers and equipment technicians receive low scores.

Read on to learn about 21 high-paying positions with a conflict resolution importance level of 34 or less.

Commercial and industrial designer

Average annual salary: $67,030

Conflict resolution importance level: 29

Commercial and industrial designers develop products such as cars, toys, and appliances. They create products that are both functional and appealing by combining expertise in marketing, materials, and product use with artistic talent. 

Molecular and cellular biologist

Average annual salary: $67,790

Conflict resolution importance level: 30

Molecular and cellular biologists research and study cellular molecules and organelles to improve our understanding of cell function and organization. 

*This is the average annual salary for "microbiologists," according to the BLS.

Budget analyst

Average annual salary: $71,220

Conflict resolution importance level: 34

Budget analysts help both private and public companies organize and manage their finances. They can work anywhere from government agencies to universities, and duties include preparing budget reports and monitoring spending. 

The World Economic Forum recently announced its 2016 class of Young Global Leaders — people under the age of 40 who are changing the world — and 24 of the 121 are American.

This year's Young Global Leaders class includes leaders from an array of backgrounds. Some are famous entertainers, like actor and investor Ashton Kutcher and writer John Green, and others are inventors, CEOs, philanthropists, and scientists working on revolutionary ideas — such as Nina Tandon, who grows human bones with her biotech company, EpiBone. 

Once chosen by the WEF, these leaders are a part of the program for five years — they attend meetings, participate in initiatives and research, and work with the rest of the WEF's community.

Here are the 23 American leaders making a worldwide impact.

Andy Moon, SunFarmer

Andy Moon started his work in the solar energy industry in 2009 as a project developer for SunEdison. In 2013, he and a coworker started SunFarmer — a nonprofit that brings solar power to developing countries — with the help of a $2 million grant from a SunEdison foundation.

SunFarmer has completed more than 100 solar energy projects so far in Nepal, its pilot country, powering schools and health clinics as well as providing relief to victims following a pair of earthquakes last spring.

By 2020, SunFarmer’s goal is to power 4,000 hospitals, schools and water projects around the world.

Aria Finger, DoSomething.Org

After graduating from college in 2005, Aria Finger joined the nonprofit DoSomething.org to try to change the way young people give back to their communities. The organization has since grown from five employees to 55, and in the past decade it has helped 4.7 million young people started campaigns in their hometowns.

Six months ago, Finger was promoted to CEO. Her most recent campaign, Keep Guns Off Campus, encourages students to pressure their college presidents to take a stand against having guns on campus.

Ashton Kutcher, THORN: Digital Defenders of Children

The actor, producer, and tech investor started the DNA Foundation in 2011 with then-wife Demi Moore with the goal of ending child sex slavery. The company rebranded a year later to “Thorn: Digital Defenders of Children” with a more specific focus: technology’s role in the sexual exploitation of children.

With the help of partners such as Facebook, Tumblr, and Microsoft, Thorn has been battling Internet-enabled sexual abuse and providing support to victims. This past November, Kutcher announced that the organization would open an innovation lab that will allow data analysts and scientists to think up new technologies to deter online predatory behavior toward children.

NOW WATCH: How to send self-destructing messages — and other iPhone messaging tricks

If you're excited to use Apple's new Night Shift feature for the iPhone, which automatically shifts the display's color to warmer hues as the sun sets, don't assume that it's a cure-all — especially if you're still reading in bed.

You've probably heard that the crisp blue light emitted by everything from TVs to tablets to smartphones is wreaking havoc on our health.

As far as the range of visible light goes, blue light — which is also given off by the sun — is near the brightest. (If our phones and tablets weren't also graced with this blue light, we'd never be able to see our screens on a sunny day.)

But blue light also tamps down on the production of melatonin, a key hormone our brains use to tell our bodies to start preparing for sleep. That's something you don't want to be doing at night, especially right when you're heading to bed.

Enter Apple's ingenious (albeit unoriginal) solution to the problem: a feature on iPhones that transitions the screen's hue from blue to red as the sun sets.

When we talked Keck School of Medicine professor of clinical medicine and fellow of the American Academy of Sleep Medicine, Raj Dasgupta, about whether Night Shift could solve our sleep woes, his answer caught us off-guard.

"If you can’t sleep, good sleep hygiene suggests that you get up, get out of bed, and do something else, something relaxing, like going and reading a book. But nowadays people aren't doing that, they're pulling out their phones and scrolling," Dasgupta told Business Insider.

There are two major problems with this, both of which run contrary to a broader set of healthy behaviors that Dasgupta encourages in people with sleeping problems known as sleep hygeine.

1. It might encourage more night-time cellphone use, which could make things worse.

Stimulus control, which the Mayo Clinic includes on its list of components of good sleep hygeine, refers to the practice of getting rid of factors that condition the mind to resist sleep. This includes setting rules like using the bed only for sleep and leaving the bedroom if you stay awake for longer than 20 minutes.

For people who already have sleep problems, apps and features that encourage more night-time cellphone use could end up making the problem worse.

"There are lots of apps that are great that are designed to help you sleep," says Dasgupta, "but it's almost a double-edged sword because my patients are using their phone in bed to use these apps."

2. The content most of us scroll through on our phones — as opposed to what we'd read in a book — is more likely to be the kind that interferes with sleep.

Another component of good sleep hygeine is preparing for sleep by decreasing our exposure to stimulating content, like TV, social media, and the news, as we get closer to bedtime. Some experts suggest avoiding devices for an hour before bed.

"When you're going to bed, you want to do things that are relaxing, like reading a book. You want to gradually transition into sleep; you don't want your mind to be stimulated," Dasgupta says.

I'm not sure about you, but I find pretty much everything on my phone stimulating. First there are the pop-up news notifications. Then there are the group texts (not to mention the Slacks and Tweets). And, when I just can't look away, there's my Facebook newsfeed.

"At bedtime, you want to be at peace," says Dasgupta. "Things that will probably make you feel not at-peace include the news."

Despite these issues, Dasgupta says the Night Shift feature can still be a welcome tool for people with sleep issues, so long as they're also sticking to the other healthy sleep behaviors.

"I don't see a problem having it as long as we know what good sleep hygiene is," Dasgupta says.

For over a century, Coney Island has been attracting New Yorkers and tourists alike to its sandy beaches, fun carnival foods, and amusement rides.

Coney Island opened with just one roller coaster in 1895, and by 1904 had three amusement areas with many different rides: Dreamland, Luna Park, and Steeplechase Park.

When the New York subway was built in 1920, Coney Island became a place that people of all races and social status could visit, which upset the crowd of wealthy people who were previously known to migrate to that area.

Coney Island's amusement park officially reopens for the season on Saturday, March 26.

Over the years, Coney Island has undergone many changes, yet it still remains a popular place for tourists and locals. Below, see vintage photos of the popular amusement park.

The Cyclone roller coaster has been operating for almost 90 years. It officially opened in 1927.

The amusement areas at Coney Island — Dreamland, Luna Park, and Steeplechase Park — made it the largest amusement area in the nation from the end of the 19th century through World War II.

NOW WATCH: There's a hidden wire stretched above American cities — and few people know what it's for

On Thursday, America's insanely competitive Ivy League schools will announce their admissions decisions.

America's Ivy League schools — Brown, Columbia, Cornell, Dartmouth, Harvard, Princeton, University of Pennsylvania, and Yale — have some of the most competitive admissions standards in America. In fact, Harvard is America's hardest college to get into, according to rankings from the academic review site Niche.com.

The rankings are based on acceptance rates and SAT and ACT scores reported to the US Department of Education. College acceptance rates received a weighted average of 60% in the ranking computation, and SAT/ACT scores received a weighted average of 40%.

Business Insider used Niche's state filter to find out which college is the hardest to get into in each of America's 50 states and the District of Columbia. Niche reports that a few states (Alaska, Delaware, Nevada, and Wyoming) are missing from the ranking because they don't have data for enough colleges.

Scroll through to find out the most selective college in each state — and to learn about non-Ivy League schools that are also relatively competitive. 

Note: Niche used the most recent data available to calculate its rankings, usually from 2012-2013 or 2013-2014.

Silicon Valley has been grappling with gender equality and diversity for years. And a recent blog post about a pregnant startup founder shows that the issue remains a hot-button topic that the industry has yet to come to terms with. 

Peretz Partensky, a cofounder of startup Sourcery, published a post on Medium on Friday detailing the some of the experiences of his partner, who is pregnant and leading the company's latest fundraising efforts. 

Parentsky's partner, Na'ama Moran, is "not the kind of person to pretend about anything," he says. "In the third trimester, her condition is nearly impossible to hide anyway. And yet surprisingly, most investors have scrupulously avoided discussing the fact."

Left unadressed, he said, the pregnancy "lingers as a significant uncertainty and manifests itself in the form of an unconscious bias the investors themselves don’t realize."

One male venture capital investor finally did address the issue, telling Moran that "everyone you meet will wonder how your pregnancy will impact your ability to deliver the fundraising goals."

Parentsky's post was optimistic, laying out his vision for how the partners planned to deal with the issue and why he felt he needed to speak out against the double-standard around men and woman founders who become parents.

But the post prompted a lengthy discussion on the online forum Hacker News, with more than 100 comments, that shows the obstacles and attitudes that pregnant woman must still overcome even in the seemingly enlightened tech world. 

"Can you fundraise if you openly say that you have a time-intensive hobby that you will under no circumstances give up for working on your company?" wrote one commenter. "If you would not finance someone who openly says that he/she will not give up his/her time-intense hobby for the company, isn't this the same as not financing people who are pregnant?"

"From the perspective of the VC, yeah, it seems unfair to screen based on that - but it also seems unfair to screen based on looks or personality or accent or whatever, all of which is (probably?) happening," wrote another. 

Much of this is paralleled in the broader corporate world, but the topic has become a lightning rod in Silicon Valley's startup scene, where long work hours and an all-consuming devotion to the job are de rigueur. And while Silicon Valley likes to think of itself as a bastion of progressive thinking, there's plenty of evidence that it remains far behind when it comes to gender and racial diversity. A recent study by Glassdoor, for instance, found that women computer programmers earn on average 72 cents for every dollar dollar earned by men. 

"This is a great question," said another Hacker News commenter about the Medium post. "It forces the greater question: Can you 'Be Dedicated' and be more than one thing. Silicon valley seems to believe: You can't be a CEO and pregnant. You can't be a lead programmer and old (> 30). You can't love both Linux and Windows. You can't be Democrat and vote for a Republican. How did we become so decided."

Classic: '1984' by George Orwell

George Orwell wrote this anticommunist novel in 1948 to predict what 1984 would look like in London. His prediction? A totalitarian state where "Big Brother," the government, was always watching you and telling you what to think and believe.

Some of his predictions came true, like cameras being everywhere and our bodies being scanned for weapons.

In 2015, Stanford University accepted just 5% of applicants, fortifying its 125-year history as one of thebest colleges in the nation.

With esteemed alumni who include the founders of Snapchat, Google, Instagram, and Netflix, the Silicon Valley feeder school is a breeding ground for top talent.

We've tracked down 12 of the school's most impressive students to check out what America's next generation of inventors, innovators, advocates, coders, engineers, and leaders are up to.

Scroll through to meet some of Stanford's incredibly impressive students.

NOW CHECK OUT: 15 impressive students at MIT

Aashna Mago is a virtual-reality aficionado who's interning at Oculus this summer.

Class of 2017

Major: computer science

By the time she entered her freshman year at Stanford, Aashna Mago was a budding molecular biologist who'd spent several years doing research in cancer treatments at Princeton. But Mago had a change of heart when she got to Stanford and set out to learn about programming and technology and teach herself how to code.

She landed a summer internship with virtual-reality expert Mark Bolas in the Mixed Reality Lab at USC's Institute for Creative Technologies, where she honed skills in programming, 3D modeling and printing, and design.

Halfway through her sophomore year, Mago took a leave of absence from Stanford to accept a full-time position at Rothenberg Ventures, where she helped launch an in-house production studio and run the first batch of River, the world's first VR/AR accelerator.

Since returning to campus last fall, Mago has earned a Women in VR scholarship from Oculus and VR Girls; cohosted a large-scale Women in VR event in San Francisco to encourage women from diverse industries to get involved in VR; and founded Rabbit Hole VR, a group at Stanford focused on bringing more diversity to the VR community through innovative storytelling. This summer, she'll be a software engineer at Facebook-owned Oculus.

Aashna Shroff founded a coding camp for girls in India.

Class of 2017

Major: computer science 

Growing up in India, Aashna Shroff was one of two girls in her high-school computer-science class. When she arrived at Stanford, Shrof was impressed by the initiatives to get women involved in computing fields, so she decided to take those ideas back to India by founding Girls Code Camp (GCC).

Last summer, Shroff led the GCC team of Stanford students to India to teach computer-science workshops to more than 500 middle- and high-school girls. The subsequent "GCC Hack Day" produced projects ranging from medical-emergency apps to educational games.

Shroff is also championing gender diversity on campus. This quarter, she'll be doing research with Stanford's Clayman Institute for Gender Research to help detect unconscious bias in job descriptions. And she's a mentor for Girls Teaching Girls To Code, a program that teaches Bay Area high-school girls how to code.

Shroff also contributed to research at Stanford's Bio-Robotics lab on a project that allows surgeons to practice brain surgery on virtual patients. She used cutting-edge technology to create a program where sights, sounds, and forces of the virtual surgery replicate that of the operating room.

Brandon Hill is the student body vice president and a former White House intern.

Class of 2016

Major: political science, African/African-American studies 

The summer before he was set to start at Stanford, Brandon Hill was de-accepted by the university for a bad grade in physics. He decided to take a year off — something he later dubbed "Year On" during a TEDx talk — to travel more than 30,000 miles across the world on a full scholarship through Semester at Sea.

He made it to Stanford and is now vice president of the school's more than 16,000 undergraduate and graduate students. 

Hill is passionate about helping youths of color maximize their creative potential through his startup, Enza Academy. Over the last two years, Enza has trained more than 150 kids nationwide at its innovation, tech, and entrepreneurship "hack-camps," which have been sponsored by Google, Stanford, Columbia University, and Facebook. Last December, Hill and his cofounder spoke about Enza Academy at the White House, where Hill interned the summer after his freshman year at Stanford.

He's also interned at Google on the YouTube star-management team, at UNICEF in Tanzania, and for the US Department of Education. When he graduates in June, Hill plans to work full-time on his "TED meets Twitter" idea-sharing platform.

This week, I'm celebrating my five-year anniversary of living in San Francisco. 

It's been a weird half-decade around these parts: When I arrived in 2011, Facebook's IPO wasn't even a rumor, Uber was a hot young startup with an unproven business model, and people were really upset about "New Twitter." 

In other words, it was the early days of what we now recognize as the current Silicon Valley startup craze.

Since then, I've gone to some amazing parties (and even more terrible ones), met lots of interesting people, and witnessed massive changes throughout the city. My girlfriend and I even bought a house.

And while people smarter than I ruminate over whether this is a bubble now deflating, all I can do is tell you what it's been like living in San Francisco during this time of huge transition.

I grew up in the suburbs of New York City, went to college in another suburb of New York City, and then moved to Queens in New York City. By early 2011, my apartment's lease was up, and I was itching for a change.

I drastically underestimated how hard it is to get an apartment in San Francisco: A few weeks before I officially moved, I flew in just to go to open houses. Over a dozen apartment viewings later, I had been rejected every time.

I finally found a place, sight unseen, on Craigslist. Turns out it was in San Francisco's upscale-ish Lower Pacific Heights neighborhood, with all utilities included for a very reasonable rate.

Pocket, which lets you easily save articles for offline (or just convenient) reading, is one of the most useful apps I have on my phone.

But lately I’ve become obsessed with a feature many Pocket users have probably never even heard of: having a robot read articles to me.

This feature is called “Listen TTS” (text-to-speech), and has been available since last year on both iOS and Android.

The basic premise is that Pocket will scan the article you saved and read it out loud to you. Let’s get this out of the way first: it’s not perfect. The robot’s voice isn’t the quality of your latest premium audio book, and there are going to be times when it sounds awkward.

But I found that, after about the first 30 seconds, it was easy to understand. None of stories I was trying to absorb were getting lost in translation. This feature is particularly useful for my commute, which switches from “times I can stare at my phone” to “times I really shouldn’t stare at my phone.” Since Pocket tracks where you are in the narrative, you can toggle start listening and then finish by reading, or vice versa.

If you want the robot to speak faster or slower, you can also toggle that.

Here’s how you turn on the feature if you are interested in trying it out:

You can save articles to the Pocket app from places like Twitter or your desktop. They are compiled into an easy-to-read format.

To access the feature, first you click on the "three-dot" icon at the bottom of the screen.

Then you select the "Listen (TTS)" button.

NOW WATCH: No one seems to want to buy Lloyd Blankfein’s stunning Hamptons home

You might think that the best restaurant in America would be a fancy affair bursting with filet mignon — but not according to Yelp.

Yelp recently released its list of the top-rated restaurants in the US, and the top spot was snagged by a Cuban bakery and cafe called Porto's, located in Burbank, California. Part of Porto's charm is that it serves up delicious food at extremely affordable prices.

Origins

The Porto's tale begins in 1960, when the Porto family decided to leave their home in Manzanillo, Cuba, a year after Fidel Castro came to power.

After requesting permission to leave the country, Raul Sr., the family patriarch, lost his job and was sent away from his family to do manual labor for the rest of the waiting period. Rosa, his wife, also found herself out of a job, and she had three children to take care of alone.

Rosa turned to selling cakes to neighbors and friends, working to hone her recipes.

When the family moved to the US, Rosa found out that her reputation as a baker had followed her. Rosa continued to bake cakes, which Raul Sr. would deliver after finishing work as a mechanic.

When demand grew and grew, Rosa opened a 300-square-foot bakery on Sunset. By the 1980s, the whole family was involved in the operation: Rosa, Raul Sr., and their three kids. Porto's now has three locations in Southern California.

So what should you get at Porto's?

Porto's is known for its potato balls, cheese rolls (try the guava cheese rolls, one Yelp commenter recommends), and its meat pies.

Yelp commenters also like Porto's sandwiches, including the steak and Cuban ones. But one reviewer warns that if you get your sandwich to go, you won't get the "amazing plantain chips."

And if you have a sweet tooth, you shouldn't leave Porto's without checking out some of its desserts, like mango custard or dulce de leche cookies.
