Public vs. Private Schools in University Preparation

The adjustment to first-year university can be overwhelming for any high school graduates. Apprehension runs high while students question what this new chapter of their life will bring… Will you fit in and make new friends? Will you find the course load too academically challenging? It is important that students be well prepared for the transition from high school to university, but are they aware that the high school sector they attended may have already played a large role in this preparation?

Professor George Bluman, a mathematics professor at the University of British Columbia, has performed research on this topic. In his research paper, Bluman uses a two-level statistical model to determine the relationship between student performance in first-year physics courses and student variables such as high-school grades and gender. He then determines how this relationship is affected by high-school factors such as school type and location.

Check out the video below where Professor Bluman discusses the results of his study, that Vancouver public school students outperform private school students in first-year university.

Of course it is important to note that there are many academic differences between high school and university.

Firstly, high school students attend 7-8 hours worth of classes each weekday, of which attendance is mandatory. In university, however, the amount of time spent in class differs depending on the day, and whether the students attend class is their own prerogative. In addition, in high school, teachers are proactive in taking on the responsibility to ensure all students meet deadlines, complete homework assignments, and fully understand concepts. In university, however, if students struggle with course material, they must take personal initiative to refer to textbooks or attend office hours for additional help.

Ultimately, there is a larger sense of personal freedom in university when compared to high school. Students must possess a mature attitude toward their new-found independence. University can take a toll on students if they are inadequately prepared for this freedom.

If public school graduates are more academically successful in university than their private school counterparts, as Bluman’s research suggests, then it is assumed that public schools do a better job of preparing their students for University life.

After all, it is a personal choice as to whether to attend public or private schools, and there are many factors that must be considered in this decision-making process. However, the take-home message from this study is that contrary to the BC Fraser Institute Report and popular beliefs, students who have attended public schools can academically perform as well, if not better, than their private school counterparts.

Snakes on a plane! (The good kind).

No need to call Samuel L. Jackson about this one! British jet engine manufacturer, Rolls-Royce, is developing robots with a snake-like appearance for use in the detection and repair of damage to aircraft engines.

A typical jet plane engine consists of a vast number of sensors to monitor engine conditions such as pressure, temperature, and vibrations. These sensors are monitored by ground-based machines that use intelligent algorithm technology. However, what if a bird were to hit a fan, or debris damage a compressor blade? For issues such as these, engine inspection is required.

Engine inspection is currently the job of a fibre-optic device called a borescope, which can be manually placed into a jet engine port by a borescope specialist. Unfortunately, there are far too few of these specialists available to operate borescopes within the 14,000 Rolls-Royce engines, flown by 500 airlines on 4000 aircraft worldwide.

“We don’t have enough specialists to go around so we need to automate this capability,” says Rolls-Royce senior vice-president Pat Emmott.

Another problem with the borescope is that once it detects an engine issue, the plane must be entirely taken out of commission in order to disassemble and repair the engine. This process is a setback that costs airlines millions of dollars.

Rolls-Royce aims to mitigate these challenges through the use of robotic snakes. This initiative is part of a €4 million European research project called “MIRoR”, which aims to be completed by July 2014. The hope is that these robots will potentially save significant time and money when airlines run into engine problems.

Wondering how they work? The snake robots enter an engine and are remotely controlled to relay images to an expert. Keep in mind that a running aircraft engine can reach up to 3,000-degree Fahrenheit temperatures. “These cameras won’t have to operate at engine temperatures — just survive them,” says Emmott. “So we’re going to need some interesting ways to keep them cool.” In addition to a camera, the snakes will also exhibit a UV laser to detect blade fractures, and an apparatus to sand down damaged compressor blades.

The snake will have to be of a substantial length in order to be effective for use in a jet engine. Rob Bukingham, director of OC Robotics in the UK, sees battling gravity as the biggest issue in this innovation, since the longer the snake, the more difficult it will be to control. According to Buckingham “the more joints you add, the more difficult it becomes to maintain the curviness.”

Interested to see these cool snakes in action? Take a look at this video to see a similarly designed robot snake designed by OC robots. This particular snake is able to cut metal and concrete!

Turning tables: a male birth control pill on the horizon.

This is a newsworthy topic I came across earlier this year and thought would be interesting to share…

For years the birth control burden has been placed mainly on women. Female protection for unwanted pregnancy is available in the form of patches, pills, rings, coils, implanted devices… the list goes on! Male contraception, however, is limited and consists of finicky condoms or the permanency of a vasectomy, two methods which have been around since the 1950s.

Despite strong demand, the successful creation of a male contraceptive pill has yet to be realized. While female contraceptives can affect hormones such as estrogen, drug companies have avoided tampering with the male hormone, testosterone, since it can result in a number of unwanted side effects including increased risk of prostate cancer, or breast enlargement (never a good look!).

Recently, a group of researchers led by Martin Matzuk at Baylor College of Medicine and James Bradner at Dana-Farber Cancer Institute, accidentally came across a drug called JQ1 that can inhibit a gene necessary for sperm production, causing testicles to “forget” how to create sperm. This drug has yet to be tested on humans, but showed positive results on mice, with those tested returning to complete fertility once the drug use was fully stopped. Qinglei Li, a member of the research team, states, “it stopped the sperm production very dramatically. More good news is that there appear to be no side effects whatsoever. Once the JQ1 was no longer given to the mice, they were back to their normal reproduction rates, and it did not affect mating behaviour or the health of the offspring.”

According to a study by the Centers for Disease Control and Prevention, in 2006 approximately 49 percent of births in the U.S. were unplanned, despite the birth control options available for women. The introduction of a male birth control pill to the market could potentially lower this rate. Dr. Matzuk and his research team intend to continue their testing and adjust the structure of the drug in order to minimize the chance of any undesirable side effects. Dr. Matzuk believes that the drug will hopefully be available for human use within the next decade.

Although it is an exciting idea for women and men to be able to share the birth control responsibility, the question to consider is whether men would be willing to take such a pill if it were available to them?

Check out this interview with gynaecologist Dr. Sujatha Reddy on how the male birth control pill would work.

A bitter pill? Illegal narcotics to treat PTSD.

While it is known as a popular (but illegal) club drug, MDMA – which also goes by the street name, Ecstasy – is being clinically studied for use in the treatment of Post-Traumatic Stress Disorder (PTSD).

PTSD is a severe anxiety disorder that can develop after experiencing a psychologically traumatic event such as war, rape, childhood abuse, or a serious accident. Treatment of this condition can take a number of years, yet at least one-third of PTSD sufferers will never fully recover.

MDMA has the ability to stimulate a sense of happiness, promote closeness to others, and reduce anxiety. Researchers concerned with the underlying psychology of PTSD are discovering that MDMA, when taken by individuals who have the condition, demonstrate therapeutic benefits. MDMA appears to assist with the process of coming to terms with personal experiences, and controlling intrusive and traumatic memories.

Professor David Nutt, a psychiatrist and former drug advisor for the UK government, is a leading researcher on the therapeutic effects of MDMA. His view is that while MDMA has been made illegal in order to prevent youth from drug abuse, its therapeutic value has been overlooked. It must be added, however, that this is the same David Nutt who was asked to resign after he claimed that ecstasy and LSD were less dangerous than alcohol.

In a recent interview with BBC Radio 4, Professor Nutt discusses why the drug is being studied in clinical research and how it could be useful for treating the condition of PTSD. Click here to listen to a short segment of this interview.

Professor Nutt recently undertook a research study to test the benefits of MDMA for individuals experiencing PTSD, of which the results were promising. In this study, 12 treatment group subjects were given MDMA pills, while 8 control group subjects were given placebo pills. Both treatments were taken alongside therapy sessions. Results showed that ten subjects in the treatment group showed an improvement after two therapy sessions.

Even here in Vancouver, Psychologist Andrew Feldmar, Ph.D., is about to begin a similar study alongside Health Canada. Check out the video below where he talks about the importance of MDMA-assisted psychotherapy research for PTSD.

All in all, the use of illegal drugs as medicine is not a new occurrence. For example, medical marijuana has long been recommended as a treatment for pain, and is increasingly used in mainstream medicine. Ingredients from magic mushrooms have demonstrated calming effects on patients entering a late stage of cancer. There are other examples of the use of illegal drugs to address medical conditions. Will MDMA follow the same path?
