Graduate students with non-STEM degrees increasingly dependent on welfare programs

Excerpt:

Melissa Bruninga-Matteau, a medieval-history Ph.D. and adjunct professor who gets food stamps: “I’ve been able to make enough to live on. Until now.”

“I am not a welfare queen,” says Melissa Bruninga-Matteau.

That’s how she feels compelled to start a conversation about how she, a white woman with a Ph.D. in medieval history and an adjunct professor, came to rely on food stamps and Medicaid. Ms. Bruninga-Matteau, a 43-year-old single mother who teaches two humanities courses at Yavapai College, in Prescott, Ariz., says the stereotype of the people receiving such aid does not reflect reality. Recipients include growing numbers of people like her, the highly educated, whose advanced degrees have not insulated them from financial hardship.

“I find it horrifying that someone who stands in front of college classes and teaches is on welfare,” she says.

Ms. Bruninga-Matteau grew up in an upper-middle class family in Montana that valued hard work and saw educational achievement as the pathway to a successful career and a prosperous life. She entered graduate school at the University of California at Irvine in 2002, idealistic about landing a tenure-track job in her field. She never imagined that she’d end up trying to eke out a living, teaching college for poverty wages, with no benefits or job security.

Ms. Bruninga-Matteau always wanted to teach. She started working as an adjunct in graduate school. This semester she is working 20 hours each week, prepping, teaching, advising, and grading papers for two courses at Yavapai, a community college with campuses in Chino Valley, Clarkdale, Prescott, Prescott Valley, and Sedona. Her take-home pay is $900 a month, of which $750 goes to rent. Each week, she spends $40 on gas to get her to the campus; she lives 43 miles away, where housing is cheaper.

Ms. Bruninga-Matteau does not blame Yavapai College for her situation but rather the “systematic defunding of higher education.” In Arizona last year, Gov. Jan Brewer, a Republican, signed a budget that cut the state’s allocation to Yavapai’s operating budget from $4.3-million to $900,000, which represented a 7.6 percent reduction in the college’s operating budget. The cut led to an 18,000-hour reduction in the use of part-time faculty like Ms. Bruninga-Matteau.

“The media gives us this image that people who are on public assistance are dropouts, on drugs or alcohol, and are irresponsible,” she says. “I’m not irresponsible. I’m highly educated. I have a whole lot of skills besides knowing about medieval history, and I’ve had other jobs. I’ve never made a lot of money, but I’ve been able to make enough to live on. Until now.”

She’s irresponsible, because she expects the people who choose to study rather difficult and unpleasant subjects like nursing and computer science and economics to pay for her lifestyle through taxation and “higher education funding”. I do think it’s important to point out that the main driver of higher tuition is increasing government funding of education, and that this increasing funding of higher education is nothing but corporate welfare.

Excerpt:

The most obvious way that colleges might capture federal student aid is by raising tuition. Research to date has been inconclusive, but Stephanie Riegg Cellini of George Washington University and Claudia Goldin of Harvard have provided compelling new analysis. Cellini and Goldin looked at for-profit colleges, utilizing the key distinction that only some for-profit schools are eligible for federal aid. Riegg and Goldin find that that aid-eligible institutions “charge much higher tuition … across all states, samples, and specifications,” even when controlling for the content and quality of courses. The 75 percent difference in tuition between aid-eligible and ineligible for-profit colleges — an amount comparable to average per-student federal assistance — suggests that “institutions may indeed raise tuition to capture the maximum grant aid available.”

Here are some of the comments that I posted in a Facebook discussion about the CHE story:

I know that some may disagree with me, but this is why people need to focus on STEM fields and stay away from artsy stuff and Ph.Ds in general. We are in a recession. Trade school and STEM degrees only until things improve.

Also, no single motherhood by choice. Get married before you have children, and make sure you vet the husband carefully for his ability to protect, provide, commit and lead on moral and spiritual issues. This woman is not a victim. She chose her life, and the rest of us are paying for it. Nice tattoos by the way – that will really help when she’s looking for a job.

I am actually better at English than computer science, but I find myself with a BS and MS in computer science. We don’t get to do what we like. We do what we have to in order to be effective as Christians. According to the Bible, men have an obligation to not engage in premarital sex, and to marry before having children, and to provide for their families, or they have denied the faith. I would like to have studied English, but the Bible says no way.

I have no problem with people who can make a career out of the arts, like a Robert George or a William Lane Craig. But you can’t just go crazy. And I think men have a lot less freedom than women to choose their major, we have the obligation to be providers and we have to be selected by women based on whether we can fulfill that role (among other roles).

Women have more freedom because they are not saddled with the provider role like men are. However, I think that the times now are different than before. There is more discrimination against conservatives on campus in non-STEM fields and fewer non-STEM jobs in a competitive global economy. The safest fields are things like petroleum engineering, software engineering, etc.

If [people who major in the humanities] can make a living and support a family without relying on government-controlled redistribution of wealth, then I salute and encourage you. If you rely on the government, know that this money is being taken away from those who are doing things they don’t like at all in order to be independent and self-reliant. It is never good to be dependent on government. That money comes from people like me.

In response to an artsy challenger:

I am happy to be scorned by those who make poor choices so long as I can have my money back from them so that I can pursue my dreams. I didn’t see any of these artsy people in the lab at 4 AM completing their operating system class assignments, nor do I see them here working overtime on the weekend in the office. They can say anything and feel anything they want, and write plays and poetry all about their feelings, too. Just give me the money I earned back first. It’s not their money. They have no right to it.

One person asked why I was “always winter, never Christmas”, and I replied:

It is Christmas for the Christians who I send books and DVDs to, as well as for the Christian scholars I support, and the Christian conferences, debates and lectures I underwrite across the world. Unfortunately, every dollar taken from me is a dollar less for that Ph.D tuition of a Christian debater, a dollar less for the flight of that Christian apologetics speaker, a dollar less for that textbook for that Christian biology student, and a dollar less for the flowers being sent to that post-abortive woman who I counseled who is now in law school. I have a need for the money I earn, and when it’s sent to Planned Parenthood to pay for abortions by the government, my plan to serve God suffers. And finally, should I ever get married, I would like my wife to have the option of staying home with the children and even homeschooling them. That costs money. Somehow, I feel that given the choice between my homeschooling wife and the public school unions, the government will choose to give my money to the unions. Just a hunch.

I’m not Santa Claus – I have goals for the money I earn.

I think that people should go into the humanities when they are serious about making a career of it and can get the highest grades. But if they are coasting and only getting Bs and Cs and not paying attention in class, then drop out and go to trade school. Don’t complain later when you can’t find a job. STEM careers pay the most.

Stephen C. Meyer: does the Big Bang cosmology support atheism or theism?

Leave a comment

Here’s the 66-minute video featuring Dr. Stephen C. Meyer, who holds the Ph.D in philosophy of science from Cambridge University, and other degrees in the hard sciences. (H/T UK Apologetics)

The lecture starts really, really slowly. You can just fast-forward to the 12 minute mark, or you might die of boredom.

Topics:

  • Up until the the last 100 years or so, everyone agreed that the universe was eternal
  • This is at odds with the traditional Christian view that God created the universe
  • Materialism, the view that matter is all there is, requires eternally existing matter
  • Discovery #1: Hubble discovers that the universe is expanding (redshift observation)
  • The expanding universe was resisted by proponents of the eternal universe, like Einstein
  • Some naturalists even proposed speculative static models like the steady-state model
  • However, not of the speculative models fit with observations and experimental results
  • Discovery #2: Penzias and Wilson discover the cosmic microwave background radiation
  • Measurements of this background radiation confirmed a prediction of the Big Bang theory
  • The steady-state theory was falsified of by the discovery of this background radiation
  • The oscillating model was proposed to prevent the need for an absolute beginning
  • But the oscillating model is not eternal, it loses energy on each “bounce”
  • A paper by Alan Guth and Marc Sher from 1982 proved that our universe will not bounce
  • In addition, experiments reveal that the universe will expand forever, and not contract
  • The beginning of the universe is more at home in a theistic worldview than an atheistic one
  • The beginning of the universe fits in well with the Bible, e.g. – Genesis 1, Titus 1, etc.

In case you are wondering about what the evidence is for the Big Bang, here are 3 of the evidences that are most commonly offered:

Three main observational results over the past century led astronomers to become certain that the universe began with the big bang. First, they found out that the universe is expanding—meaning that the separations between galaxies are becoming larger and larger. This led them to deduce that everything used to be extremely close together before some kind of explosion. Second, the big bang perfectly explains the abundance of helium and other nuclei like deuterium (an isotope of hydrogen) in the universe. A hot, dense, and expanding environment at the beginning could produce these nuclei in the abundance we observe today. Third, astronomers could actually observe the cosmic background radiation—the afterglow of the explosion—from every direction in the universe. This last evidence so conclusively confirmed the theory of the universe’s beginning that Stephen Hawking said, “It is the discovery of the century, if not of all time.”

This is a good article to send to atheists who are not comfortable with what the progress of science has revealed about the beginning of the universe, and of time itself. If you look in agnostic astronomer Robert Jastrow’s book “God and the Astronomers” (2nd edition), you’ll find 6 evidences.

By the way, Dr. Meyer also does a great job of explaining the problem of proteins, DNA and the origin of life in this lecture. And you can hear him defend his views in this debate podcast with Keith Fox and in this debate podcast with Peter Atkins. He does a great job in these debates.

Scientists discover that tides affect a planet’s habitability

Circumstellar Habitable Zone
Circumstellar Habitable Zone

Science Daily reports on a new factor that affects planetary habitability: tides. Specifically, tides can affect the surface temperature of a planet, which has to be within a certain range in order to support liquid water – a requirement for life of any conceivable kind.

Excerpt:

Tides can render the so-called “habitable zone” around low-mass stars uninhabitable. This is the main result of a recently published study by a team of astronomers led by René Heller of the Astrophysical Institute Potsdam.

[…]Until now, the two main drivers thought to determine a planet’s temperature were the distance to the central star and the composition of the planet’s atmosphere. By studying the tides caused by low-mass stars on their potential earth-like companions, Heller and his colleagues have concluded that tidal effects modify the traditional concept of the habitable zone.

Heller deduced this from three different effects. Firstly, tides can cause the axis of a planet`s rotation to become perpendicular to its orbit in just a few million years. In comparison, Earth’s axis of rotation is inclined by 23.5 degrees — an effect which causes our seasons. Owing to this effect, there would be no seasonal variation on such Earth-like planets in the habitable zone of low-mass stars. These planets would have huge temperature differences between their poles, which would be in perpetual deep freeze, and their hot equators which in the long run would evaporate any atmosphere. This temperature difference would cause extreme winds and storms.

The second effect of these tides would be to heat up the exoplanet, similar to the tidal heating of Io, a moon of Jupiter that shows global vulcanism.

Finally, tides can cause the rotational period of the planet (the planet’s “day”) to synchronize with the orbital period (the planet’s “year”). This situation is identical to the Earth-moon setup: the moon only shows Earth one face, the other side being known as “the dark side of the moon.” As a result one half of the exoplanet receives extreme radiation from the star while the other half freezes in eternal darkness.

The habitable zone around low-mass stars is therefore not very comfortable — it may even be uninhabitable.

Here is my previous post on the factors needed for a habitable planet. Now we just have one more. I actually find this article sort of odd, because my understanding of stars was that only high-mass stars could support life at all. This is because if the mass of the planet was too low, the habitable zone wouldbe very close to the star. Being too close to the star causes tidal locking, which means that the planet doesn’t spin on its axis at all, and the same side faces the star. This is a life killer.

This astrophysicist who teaches at the University of Wisconsin explains it better than me.

Excerpt:

Higher-mass stars tend to be larger and luminous than their lower-mass counterparts. Therefore, their habitable zones are situated further out. In addition, however, their HZs are much broader. As an illustration,

  • a 0.2 solar-mass star’s HZ extends from 0.1 to 0.2 AU
  • a 1.0 solar-mass star’s HZ extends from 1 to 2 AU
  • a 40 solar-mass star’s HZ extends from 350 to 600 AU

On these grounds, it would seem that high-mass starts are the best candidates for finding planets within a habitable zone. However, these stars emit most of their radiation in the far ultraviolet (FUV), which can be highly damaging to life, and also contributes to photodissociation and the loss of water. Furthermore, the lifetimes of these stars is so short (around 10 million years) that there is not enough time for life to begin.

Very low mass stars have the longest lifetimes of all, but their HZs are very close in and very narrow. Therefore, the chances of a planet being formed within the HZ are small. Additionally, even if a planet did form within the HZ, it would become tidally locked, so that the same hemisphere always faced the star. Even though liquid water might exist on such a planet, the climactic conditions would probably be too severe to permit life.

In between the high- and low-mass stars lie those like our own Sun, which make up about 15% percent of the stars in the galaxy. These have reasonably-broad HZs, do not suffer from FUV irradiation, and have lifetimes of the order of 10 billion years. Therefore, they are the best candidates for harbouring planets where life might be able to begin.

This guy is just someone I found through a web search. He has a support-the-unions-sticker on his web page, so he’s a liberal crackpot. But he makes my point, anyway, so that’s good enough for me.

Maybe the new discovery is talking about this now, but I already knew about the tides and habitability, because I watched The Privileged Planet DVD. Actually that whole video is online, and the clip that talks about the habitable zone and water is linked in this blog post I wrote before.
