Waching daily Jan 5 2018

SiFi: MAPFRE had the biggest run.

Mark: And then we were next.

SiFi: And then we were next.

Any the other guys were similar.

But actually, we were 5 or 6 degrees higher than these guys.

Mark: So that's good.

SiFi: So basically we have gone down and forward.

They are 303 and 307, I think they were.

We are 311 and 309 before.

Kinda feels like the general theme, if you see what I mean

You make efficient progress north, and then as you get more headed then you have more

escape zone and you play with the east/west.

Mark: Good news, Gain on everyone except for MAPFRE.

MAPFRE had the longest run, they were also the lowest.

We had the next longest run.

And Azko and Dongfeng were 303 and 307.

I thought they were going to be a lot further forward.

This leg is quite different to the last one.

Not just because the sea temperature is 20 degrees warmer either.

Last time we spent a lot time trying to get as far south as we could against the ice gate

that always shortens up the distance and always put us in the better breeze.

Strategically, although there were options, they were pretty limited to being down on

the ice wall than trying to manage this.

This is a slightly more of a taxing mental challenge it is fair to say.

It's quite interesting coming up here, we are working our way north.

Trying to get our self into the Easterly tradewinds and up to the Doldrums.

But there is quite a lot of scope east-west that you can play.

There are also some reefs and shallows that we have to play a little bit of attention

to.

Makes it for quite an open race track.

We actually see between the boats.

Although the routes are urging us one way or the other, everyone is sort of playing

it a little bit and feeling their way out.

The last position report was quite important and its given us a little bit of confidence

in the fact that that we don't need to gybe down again and setup further in the west.

So that's encouraging.

Sometimes it's nice when you know where everybody is going and where everyone is going to go

and you just need to execute that and plan the best you can.

It is enjoyable when there is a little bit of subtly involved.

I think when you get these situations where it is quite subtle and quite nuanced.

The boats that do the sail changes as well, and sail the boat fast and nail their angles

well get rewarded.

I guess it is something that really does reward both good navigation and good sail performance

on deck.

It's more rewarding when we are not just all hammering in one direction.

If we get it right then, I do enjoy it.

Trump

Department of Energy Invests $30 Million to Attack US Dependence on Mideast Oil

The Energy Department plowed tens of millions of dollars into projects designed to explore

new fracking technology as the U.S. leans heavily on natural gas amid harsh winter weather.

DOE�s decision will help the agency master oil and gas development in untapped, energy-rich

areas, according to a press statement Wednesday from the agency.

The funding targets the Tuscaloosa Marine Shale in Texas and the Huron Shale, which

spans four states in the Appalachian.

The effort will help �strengthen America�s energy dominance, protect air and water quality,

position the nation as a global leader in unconventional oil and natural gas (UOG) resource

development technologies, and ensure the maximum value of the nation�s resource endowment

is realized,� the statement notes.

DOE�s funding effort comes shortly after Americans consumed a record-breaking amount

of gas during the most-recent cold snap, according to data from PointLogic Energy, an oil and

gas firm that monitors gas usage

7 Signs The People You Are With Radiate Negativity - Duration: 2:53.

7 Signs The People You Are With Radiate Negativity

It is important to be with good people.

However, sometimes you just do not know whether someone actually gives you positive or negative

feedback to you.

Here is some signs to reconsider the people around you.

You can either motivate them or avoid them completely for positive life.

if you experience any of these 7 signs, the people you are with are radiating negativity

#1 - Constant worries

People radiating negative energy always worry too much about something.

It goes beyond your thinking and make you want to push yourself from a cliff.

#2 - Pessimist

Small matters are big matters.

They think that something small will affect the whole world of theirs.

Indeed, it is important to look at details.

However, too much work on details take so much time especially if they always think

it cannot be done.

If advice does not work on them, just leave them.

#3 - Frequent whining

Their issues are the greatest, and no one should not complain about that.

Only the negative people can whine and say that their world is the worst that comes to

them.

If you meet this kind of person, you should be ready to bring them back into reality.

#4 - Delusionary

Being afraid of leaving their comfort zone, negative people tend to have monotonous live.

You can identify this, and be sure you ask them to hang out sometimes especially if they

are your friend.

#5 - Never reach the true potential

Negative people are surrounding by monotonous life with no intention to upgrade skills,

ability, attitude, and appearance.

This makes them perform worse in any form of competition.

#6 - Absorbing energy

Your positive energy is traded with their negative energy.

You can imagine that when you are having conversation with them as their topics are related to desperation,

uncertainty, worries, and other negativity.

#7 - Limited experience

Negative people tend to stay in one place as they do not like to improve.

In this case, they basically have little experience compared to other people who are more active.

All in all, that's the signs of people who radiate negativity.

Really cool information isn't it!

How the First Americans Got There - Duration: 4:44.

♩♩Intro♩♩

About 11 and a half thousand years ago, people in what's now central Alaska buried two

babies in a hearth.

One was was less than 6 weeks old, and the other was a late-term stillbirth.

They stayed there until 2013, when archaeologists found their remains.

And this week, a group of researchers published a detailed analysis of one of the babies'

genomes, its full genetic code, in the journal Nature.

Turns out that this one baby's DNA can tell us a lot about our history as a species.

It's the most direct evidence we have for how people first came to the Americas, and

what happened to them afterward.

Over the years, researchers have proposed lots of different theories for how the First

Americans got here.

And these days, there are at least a few things that almost everyone agrees on:

At some point, probably more than 14,000 years ago, people crossed over the Bering land bridge,

between what are now Siberia and Alaska.

From there, they spread through North and South America, splitting off into northern

Native American and southern Native American genetic groups, which are still around today.

There are plenty of unresolved questions about this, though, like when exactly the migration

happened and why the ancient Native American and East Asian genomes are so different.

Enter the babies from this week's paper.

The researchers were only able to isolate enough DNA for a full genome analysis from

the 6-week-old baby, known as USR1.

They sequenced USR1's genome and compared it to both ancient and modern genomes from

more than 2500 people.

And they found that USR1 wasn't nearly as closely related to the northern and southern

Native American groups as you might think.

It's clear they had a common ancestor.

But according to the team, the baby's genetic code was so different that it's part of

a whole separate lineage — a third group they're calling the Ancient Beringians.

That supports what's known as the Beringian standstill model, which suggests that people

first came to the areas near the land bridge, aka Beringia, something like 30,000 years

ago.

But then the ice age peaked, and the ice sheets and glaciers made travel so difficult that

the people in Beringia were basically cut off from the rest of the world for thousands

of years.

Hence the "standstill" part of the name.

According to the model, once the climate warmed up a little, people weren't trapped anymore,

and they started to move out into the rest of North and South America.

If the First Americans were stuck in Beringia for a while, breeding amongst themselves and

developing new mutations in their DNA, these changes wouldn't be shared with the East

Asian population they came from.

So you'd expect there to be a lot of diversity in the ancient Native American genome, and

the Ancient Beringian lineage tells us there was.

The findings also fit what researchers found back in 2015, when they looked at the babies'

mitochondrial DNA.

That's the separate, smaller genetic code in a cell's mitochondria, as opposed to

the nucleus.

They were able to get good samples from both USR1 and the other infant, USR2.

Even though the mitochondrial genome doesn't have as much information as the nuclear genome,

it's still a useful tool.

And it was enough to show that the two babies were each part of genetic lines you don't

generally find in today's northern Native American populations.

In other words, it showed that the babies must have come from a pretty diverse population.

But now that we have USR1's nuclear genome, we know there's more to it than that — the

Ancient Beringians were a whole separate group.

And, by comparing USR1's genome to those of other groups, the researchers were also

able to flesh out the Beringian standstill model and come up with a much more solid timeline

of when and how the First Americans moved in.

To be clear, we don't know for sure that this is exactly how it went.

But by combining this new evidence with what archaeologists have found in the past, here's

what the team thinks happened:

People first settled in the area of Northeast Asia near the land bridge around 36,000 years

ago.

But for a while after that, there were still people going back and forth to the rest of

East Asia and genes being shared between the populations.

Then, about 24,000 years ago, the cooling climate isolated them from each other.

Around 21,000 years ago, USR1's ancestors and the ancestors of both the northern and

southern Native American groups split into two separate genetic lines.

It's not clear whether they crossed over the land bridge before or after the split,

but either way, they still couldn't get very far because of all the ice.

Then, sometime around 15,700 years ago, the northern and southern Native American groups

split off from each other.

And this was right about when the climate finally warmed up a bit and people started

to move farther east, eventually spreading throughout the Americas.

About 4,000 years later, two babies were born — and died — in Eastern Beringia.

And now, 11,500 years after that, their remains have brought us the closest we've ever been

to understanding how the indigenous peoples and cultures in the western half of the planet

came to be.

Celebs No One Realizes Are Related - Duration: 3:29.

Show business can be as much of a family business as any other long-running enterprise.

While many well-known Hollywood dynasties are open about their family ties, other famous

kin choose to keep their connections more private.

Here are some celebrities you may have never realized are related.

Al Roker and Lenny Kravitz

What do the Today show weather guy who admitted to soiling his pants at the White House, and

the rocker who was once connected to an illegal Bahamian dental clinic have in common?

Their moms were cousins!

Yep, Al Roker and Lenny Kravitz are first cousins, once removed.

Liev Schreiber and Pablo Schreiber

Yep, "Stache" from Orange Is The New Black and Ray Donovan are brothers.

Half-brothers, actually.

According to the New York Post, their dad is an acting teacher who raised Pablo in British

Columbia while older brother Liev grew up in New York City.

Pablo says Liev encouraged him to make it in the industry on his own, rather than have

his famous older sibling pull strings for him, which he now views as sage advice.

Bonnie Bedelia and Macaulay Culkin

Die Hard and Parenthood star, Bonnie Bedelia, was born Bonnie Culkin.

She's the sister of Christopher "Kit" Culkin, who happens to be the dad of the famous brood

of actors that includes Home Alone star Macaulay.

As far as Bonnie's relationship to Macaulay or any of the others, it's unclear.

None of them do much press, but according to the Daily Mail, Bonnie was instrumental

in Kit's recovery following a stroke in 2014.

Warren Beatty and Shirley MacLaine

Oscar-winning siblings Warren Beatty and Shirley MacLaine have each risen to the top of their

game, they by no means did it as a team.

According to the Telegraph, they've actually been in competition all their lives, with

Beatty supposedly launching his acting career after growing tired of living in the shadow

of his already famous sister.

When Beatty hit superstardom, he stopped communicating with MacLaine for a time, at least according

to one biography.

Fortunately, the two seemed to have mended their relationship in recent years, particularly

in the wake of Beatty's now-infamous 2017 Oscars flub.

When asked how she felt watching her little brother's viral gaffe, Maclaine described

it as a "horror" to USA Today.

"I'm concerned with how he must have felt being so close to him.

I'm three years older and I'm protective."

Jayne Mansfield and Mariska Hargitay

Law and Order: SVU star, Mariska Hargitay, is the daughter of the late Jayne Mansfield,

who was a 50s pin-up girl and actress.

In 1967, Mansfield died in a car crash that also claimed the lives of two others, although

not her three children, including three-year-old Mariska, who were in the backseat.

Mansfield was just 34 years old at the time of her death.

Though she has no memories of the accident or her mother, Hargitay told Closer Weekly

that having such a famous mother was at times "a burden," and that "losing her at such a

young age is the scar of my soul."

Emma Roberts and Julia Roberts

Mega star Julia Roberts wasn't exactly enthusiastic about her niece, Scream Queens actress Emma

Roberts, following in her footsteps.

The Pretty Woman star told the Los Angeles Times in 2013 that she worried Emma wouldn't

remain "the same magical girl she used to be" after entering a business that can easily

lead one to compromise their "sense of self."

That never stopped Emma, who is also the daughter of actor Eric Roberts, Julia's brother, from

seeing her Oscar-winning aunt as a role model, and in fact, as the person responsible for

whetting her show business appetite when she was a kid.

"I would go and visit and my Mom would be like, 'Aren't you bored?

Don't you want to leave?'

I'm like, 'No, I'm working in hair and makeup now!'"

invisible pain II nowhalle II CC - Duration: 10:16.

Hello, my fellow Internetians.

Welcome to a video that probably should be scripted but I... am not doing that.

I am going to talk about invisible pain and much like pain can just come upon you, the

idea to make this video kind of just overwhelmed me.

So, here we are.

I'm going to start by taking my pulse for you which seems a bit odd that I have pulse-ox.

So, I'm going to put it on my finger- you saw it in a few of my vlogmas videos.

Vlogmas is over.

It is officially January.

I am recording this on January the 2nd.

I am not sure when it is actually going to go up and I said before that I wanted to make

a video about chronic pain.

Instead, I'm going to talk about invisible pain because types of chronic pain are invisible.

My pulse is currently 115, 119, 120, 123... so clearly I am nervous to make this.

And if you don't believe me, I will put this right here for you to see.

Maybe... maybe not, it doesn't like you.

There we go!

133, that's what I'm talking about.

Now I have to try and, yep.

Oh, now it's 140, that's lovely.

So, I am very nervous to make this.

I feel like this needs to be said and it needs to be validated.

For the longest time...

No, no, no, no, no, we're not even gonna say for the longest time.

Yesterday, on New Year's Day, at 4:00pm I went to the emergency room because I had very,

very, very bad stomach pain.

I suffer from something called gastroparesis.

Okay, there are fewer than 200,000 cases in the US per year.

And it can be treated but it can't be cured and basically it means that I have slow gut

motility.

So, I have a medication that I take four times a day, every single day, for three weeks and

then it's off for one week and then it recycles.

But I was in the ER yesterday because I had really bad stomach pain to the point where

I was laying on the ground in the bathroom crying and asking my mom for help.

I do not like asking people for help.

I do not like crying.

I was in the car with my friend, Jonathan, coming back from New York and we had just

visited my internet friend, CW, and- she's not even my internet friend, she's just my

friend.

And we were talking about books and movies and songs and I told him that none of them

had ever made me cry before.

The only thing that really makes me cry is pain and pain is invisible.

It really is.

You relate to pain, you relate your level of pain through metaphors.

It can't actually be gauged- at least I don't' think it can.

We were sitting in the waiting room of the emergency room and my mom asked me as we were

sitting there what my pain was on a scale of 1-10- as I had been in the bathroom crying-

and I told her it was an 8.

And she told me that the pain didn't look like an 8.

But pain is invisible and everybody has a different scale.

I have a migraine medication that I can take which is basically hospital grade medication

when my migraine is 3 days long and I would go to the hospital but I have medication I

can take so I don't have to.

And I rate those as 8's.

I guess 8's are kind of the highest I'm willing to go because I think of personal losses such

as grief from deaths higher than physical pain.

But physical pain is just as real.

And maybe I've been using the wrong scale.

And everybody has their own scale.

You can't tell somebody that they're not in pain.

Pain is different for everyone.

Some people have chronic pain and chronic pain is different for everyone too.

I have gastroparesis which is a chronic condition.

I have eosinophilic esophagitis which is a chronic condition.

When you're in the midst of a flare up, on those days when I have really bad migraines

and crippling stomach pain and I'm laying on the floor wondering why?

Why is this pain chronic?

Why is there nothing anyone can do about it?

I turn away from people; I push them away when I'm in pain because I tell them there

is nothing they can do about it- but there is nothing I can do about it either.

I shouldn't make myself more miserable by pushing them away, but I don't want to make

them feel bad because that causes me pain.

I don't want them to feel bad that I'm in pain because the fact that I'm in pain has

nothing to do with them.

I'm in pain because I have these chronic conditions that I can't change... but I can change how

I act about them.

I can accept people.

The medication might not always work, but friends are still there.

Like yesterday, Amy started sending me pictures of her cats when I was in the ER.

Last fall, I went to the emergency room for my stomach pain and Jenna, Nicole, and Kat,

who had been my roommate at the time, stayed up with me until 2:00am when my parents could

get to school.

And we were watching The Amazing Tour is Not on Fire and the documentary and they were

sending me pictures of goats and they were trying to make me laugh and feel better even

though I was in such pain.

I can be an advocate.

I don't know how to be an advocate, but I can be.

When I'm laying on the floor and I'm in such pain and pushing people away and I'm wondering

why it's all happening to me, this is why.

I don't know how to be an advocate I really don't.

I'm 19 years old, I'm trying to make my way through school, I'm fighting to stay in school

right now because my school doesn't really want me there.

But there is a reason this is happening.

And the reason is so that I can talk about it, maybe?

So that I can tell others about it?

So that I can speak for invisible pain and invisible illnesses that can't speak for themselves.

I don't really know.

I haven't washed my hair in two days, my face is breaking out, my head hurts, I had a ruptured

ovarian cyst yesterday which is why that pain had been so terrible.

I have multiple doctor's appointments a week, I'm trying to be at school and study 16-18

credits at a time while also producing a campus version of Survivor, go to physical therapy

for my hip- I'm literally loading myself up so much because I just try to keep going.

That's the only way I know how to keep going.

But I realize I have- sometimes I have to slow down.

You have to embrace the pain and you have to speak out about it.

You have to tell others when you're hurting be it emotionally or physically or however

you hurt because while it can be difficult to make the pain itself stop, and sometimes

you can't get the pain to stop, you can be with people who care about you.

This wasn't my intended first video of the year.

I suppose it's a good thing, this is me telling myself that in 2018 I want to be an advocate.

I suppose that's it.

I have a new end-screen that will come on after I finish talking.

Thank you to Amy for that and my header and my new watermark.

The next video, fingers crossed, shall be me, CW, and Jonathan when we went to New York.

It was supposed to be my last 2017 video, but then I was having computer issues and

I had to wipe the entire hard drive and reinstall programs and whatnot...

Anyway, if you enjoyed this video, please give it a thumbs up.

This year I am going to try to talk out more about migraines, about stomach pain, about

rare diseases, about common diseases, about mental health.

I want to be an advocate.

I want to speak for the things that aren't spoken about or that are spoken about.

This is me saying I'm not going to be quiet.

I am not going to just sit in pain and deal with it because I am in pain for a reason

and I think that reason is to tell others that they are not alone.

So even though they might not be ready to speak out, I am.

So, if you liked this video, please give it a thumbs up.

Share it with people, subscribe to my channel so that you can see more, and as always, thanks

for watching!

A New, Bubbly Origin Story for the Solar System - Duration: 5:33.

[ ♪ Intro ♪ ]

With all the bigger cosmological mysteries like dark matter, dark energy, or what happens

at the center of a black hole, you might think a question as local as "How was our solar

system born?" was solved a long time ago.

Nope.

But we might be a little closer to solving that puzzle, thanks to a new paper published

in the Astrophysical Journal a couple of weeks ago.

Right now, the most widely-accepted hypothesis for how the Solar System came to be starts

about 5 billion years ago with a nearby supernova, an exploding star.

The shockwave from the explosion would have triggered the collapse of the large cloud

of gas and dust that eventually became the Sun, planets, and all the other stuff in the

Solar System — including us, eventually.

But here's the problem.

A supernova would also infuse our cloud with certain elements.

They release aluminum-26, a type of aluminum with 13 neutrons, and iron-60, a type of iron

with 34 neutrons that you can only get from the explosion of a massive star.

The thing is, the amount of aluminum-26 and iron-60 we've measured in our solar system

doesn't match what we should have gotten from a supernova.

Meteorites, which are a good way to measure the composition of the Solar System since

they come from space, do have more aluminum-26 than what we find on average across the galaxy.

But we're low on iron-60.

And a supernova would have injected both into our system — not just extra aluminum.

So in this new paper, a group of astronomers proposed a different idea: maybe the Solar

System didn't start with a supernova.

Maybe it started with the wind-blown bubble surrounding a star 40-50 times the mass of

the Sun — a type of star called a Wolf-Rayet star.

Wolf-Rayet stars are basically the most massive and hottest-burning class of stars in the universe.

They've already exhausted all their hydrogen fuel, so they're fusing heavier elements

instead, and they have a really hard time holding themselves together.

Their stellar wind, the gas streaming out from the star, is so strong that they lose

about 3 Earths'-worth of mass every year.

The violence inside them forces heavier elements upward, too, so it's not just a bunch of

helium getting spewed out into space.

In fact, Wolf-Rayet stars release a lot of aluminum-26 … but not iron-60.

Which sure sounds a lot like our solar system!

These stars' high-velocity winds and extreme temperatures create a huge bubble structure,

including a shell of denser gas and dust that could eventually condense into stars.

Based on their computer simulations, the team estimates that anywhere between 1-16% of all

Sun-like stars could be formed in Wolf-Rayet star wind bubbles.

Of course, we don't know for sure.

For one thing, this model assumes the meteorite data gives us a true representation of what

the early solar system looked like, which we'll never be able to know without a time machine.

This is a very new hypothesis, and until we have more research, most astronomers are probably

going to stick with the supernova idea for now.

But it does fit pretty nicely.

While some astronomers are working on solving that 5 billion-year-old puzzle, others are

continuing to explore the system we call home.

And now we've taken the next step in planning another mission!

In late December, NASA announced two finalists for the next New Frontiers mission, which

both sound awesome:

One would sample a comet, and the other would send a nuclear-powered quadcopter to Titan,

Saturn's largest moon.

Even if you've never heard of the New Frontiers mission program by name, you've probably

heard about at least one of the three missions that came out of it: New Horizons, Juno, and OSIRIS-REx.

The first of the two finalists bidding to be the fourth member of this special club

is the Comet Astrobiology Exploration Sample Return mission, or CAESAR.

It would be a follow-up to the ESA's Rosetta mission, which visited and landed the Philae

probe on comet 67P/Churyumov-Gerasimenko in 2014.

But CAESAR would go beyond that mission — it would actually collect a 100-gram sample of

the comet's surface and return it to Earth.

The Japanese space agency JAXA would use its experience from their asteroid sample return

mission Hayabusa to design CAESAR's return capsule, which would return to Earth in November 2038.

That might seem pretty far-off, but this is a whole new space mission we're talking about.

It takes a lot of planning!

If the Dragonfly mission is selected instead, it would arrive at Titan by 2034.

Like 67P, we've landed on Titan before — with the Huygens probe, back in 2005.

It even sent back pictures of the surface.

But this time we'd get to go flying.

With Titan's low gravity and super thick atmosphere, you could actually fly around

by just strapping on wings and flapping your arms a bunch, which sounds like the best thing ever.

But it's tough to send an astronaut all the way out there when we haven't even gotten

one to Mars yet, so a quadcopter is the next best thing.

Because of all those clouds and Titan's distance from the Sun, solar power isn't an option.

So, like a certain famous DeLorean time machine from the 1980s, it would be powered by plutonium.

Legally acquired, though.

And the waste heat produced by the generator would be used to keep the electronics from

getting too cold.

Dragonfly would land at a bunch of different geologic sites covering hundreds of kilometers,

and use a drill to sample pieces of Titan's surface and analyze its composition.

That includes hunting for chemical signatures that could indicate the presence of life.

It would also look for any possible seismic activity and profile atmospheric conditions,

giving us a better sense of what life would be like on this weird alien moon where it

rains methane instead of water.

The teams working on both projects will receive funding through the end of 2018 to keep developing

them, and NASA will select the winner in spring of 2019.

So I guess we'll just have to stay tuned to find out which project gets the go-ahead.

Tips for Student Success in 2018 | Ashford University - Duration: 4:18.

Ben: Happy New Year, Ashford, my name is Ben Gothia, and this is Promoting Awareness and

Wellness in Students.

Every January, we focus on starting the New Year with a fresh perspective.

This month we reached out to Ashford Staff who interact with students the most and asked

them for some advice to give to active and potential students.

Welcome to PAWs!

We asked staff members from our enrollment and advising departments two different questions:

The first was, what is your idea of a successful student?

The second question was, what Ashford resources do you hope every student will utilize while

pursuing their degree?

Here they are!

Jacquelyn Bullis: A successful student is one that stays focused, understands the importance

of their education, and tries their very best in each and every course.

It is very difficult to manage work, family, and school, but a student that can balance

and prioritize these aspects will be successful.

I always tell my students that a great way to succeed in their degree is working ahead,

you can submit assignments to the writing center for review and feedback, get a jump

start on the next week's coursework, and if something comes up then you won't be

behind.

Also, I think it's important for students to get the most out of their degree, talk

to your advisors about minors, specializations, Honors College, Golden Key, Champs.

These are all ways to add weight to your degree, expand your network, and get more out of college

in general.

David Miller: To me, a successful student sets up a weekly schedule to incorporate their

studying and assignment time into their personal and work activities.

Proper time management is crucial to becoming a successful student.

In my opinion, develop a routine and stick to it.

I hope every student will utilize the Ashford Writing Center and Library.

The Writing Center is an amazing resource with many tools.

There are sample papers that illustrate how to format papers in proper APA format.

Also, there is a thesis building tool that asks users a series of questions about their

topic and generates a succinct thesis statement.

Roni Moore: My idea of a successful student is one who is a good listener, asks questions,

and who communicates, whether it's verbally on the phone, or through emails.

A successful student is also one who is proactive and good at meeting deadlines.

Especially since everything here is online and there is no face to face.

Getting their financial aid documents completed early and completing homework assignments

early or on time are essential to their success in class.

I hope every student utilizes their enrollment services advisor and student advisor to the

fullest while pursuing their degree here.

Do not be afraid to ask questions.

I also hope that every student utilizes their student portal resources; such as the writing

center, library, and career services- along with ION tuition.

This keeps track of their student loan information and repayment options.

Ashley Howerton: A successful student is someone who fosters relationships with their classmates

and their professors.

Someone who does not just get by and do the minimum amount required to pass but really

works hard to understand the material provided in the classroom.

Ultimately, a successful student is looking ahead to their future and prioritizing their

education.

Ashford offers resources for all students and alumni to really help in all aspects of

their education and careers.

A few examples include: C.H.A.M.P.S, which is a peer mentoring program where you learn

online learning strategies from students who are already successful.

A Writing Center that offers 24/7 Live Chat support and feedback for written assignments

within 24 hours.

And, of course, Career Services.

You can complete assessments for skills and personality, get help with resume building

and career guidance.
