Happy New Year Sri Lanka!

We, Sri Lankans, use the “Western Calendar” (formally known as the Gregorian calendar) for most of the practical day-to-day activities like the rest of the world. Therefore, it is reasonable to expect our celebrating the beginning of the calendar year. Recently, with the influence of ICT, I see a trend of celebrating this new year from top to bottom with the president sending wishes to your mobile phones and layman celebrating at least with a greeting.

However, we Sri Lankans, is this the only new year we celebrate within a year (365+ days)? The answer is no! If you are from the majority of Sri Lankans, you will also celebrate the beginning of the Buddhist calendar and if you are one of the minorities, you will either celebrate the beginning of either the Hindu or the Islamic calendars. Again, a Sri Lankan Hindu, generally being a Tamil would also like to celebrate an alternative date (beginning of Tamil “Thai” month).

Given that how much we as a country care about every race and religion of this country, we declare national holidays for most of the above celebrate the new years with our fellow citizens, our brothers and sisters!

To add to this list, I am sure, we are not far away from declaring the first day of the Chinese calendar as a holiday. We Sri Lankans should be glad, as how much we love our holidays in this part of the world!

Happy New Year 2012!

Before It’s Too Late: The General Elective Syndrome

Quite a long time ago, when I wrote about the Technical Elective Syndrome and I promised that I would write about the other side of the coin in the place where I work/teach (and literally live). However, it slipped my mind for a while and finally, here we go.

The topic is on General Electives - none technical courses offered to Engineering students at our faculty. When we were students not so long ago, we never had a change to follow such courses. I am talking about courses like music, cinema and television, political issues in Sri Lanka, economics and management, etc. They were first brought into the scene with the introduction of the so-called “course-unit” system or the “semester” system.

At the time of introduction, the general elective courses were put into three baskets and the students were asked to choose 15 credits from the three (with the condition of choosing a minimum of two credits from each basket). Fifteen credits is considerably a large portion of their courses: for comparison, the total amount of credits one has to complete to claim for his/her degree is 150 credits and therefore this is 10% of their total workload of four years.

All looks good and it was expected to be really useful and nice. I quote the following from the student guide to give you an idea of what is expected: “General elective courses are designed to enable the students to gain a broader perspective of their roles as professionals as well as citizens in our pluralistic society…”.

However, here is the catch and the cause of this article: although, you need to pass the 15 credits to complete your degree, the grades you get for these courses are not counted towards your merit/class/GPA. Therefore, the students do not feel the need to obtain good grades for these courses, as they are not counted towards their merits. It is typical to see that a student getting good grades for his/her technical courses would have pass grades (typically C grades, which are equivalent to 50%) for these courses. It is also believe that these courses are not considered seriously by the administration and therefore lack of support (timetabling, releasing grades, etc.) for these courses. To add to this, these courses are mostly taught by part-time visiting teachers.

Although these courses were introduced with genuine and useful motives, my feeling is that they are not achieved here to a satisfactory level.

Finally, I am famous!

Few days ago, one created a facebook page for me. I inquired the one why (s)he did so, the answer I received was “famous people have their own facebook pages”.  Therefore, finally…..  I am famous :-)

The Technical Electives Syndrome

As most of you know, I am a University Lecturer by profession. With the introduction of the course unit system in our Universities, the prominence given to elective courses, where you allow a particular student to choose her/his courses from a pool of courses has increased tremendously. Theoretically, this is a really good move and there is no second thought about it (at least in the context of this post). In our faculty (Engineering at Peradeniya) we typically have two groups of elective pools: (1) technical electives and (2) general electives. The courses in the former pool are of technical nature for Engineering and the later are of non technical nature for Engineering (such as humanities).

What I am trying to discuss here is a side affect of technical electives (there is another totally different side affect of general electives – the General Electives Syndrome – the discussion of which I will save for another day).

Little more about the technical electives at our faculty: a typical Engineering student at our faculty will have to cover 18 credits of technical electives to qualify for graduation. This is the required number and therefore the minimum and they are allowed to take a large number if they prefer. The final GPA (grade point average) and the class (first, second upper, etc.) will be calculated based on a reasonably large amount of non-elective courses and the required 18 credits worth technical electives. A student, when graduating can indicate the technical elective courses she/he wanted to add to the total GPA calculation.

This is where the problem is: now, a student can follow as many technical electives as she/he wants and when graduating can select the ones that have good grades (to me this assumption is right only if the grades obtained are randomly distributed) and therefore a good GPA. With this mentality, most of the students adapt to this pattern (there is a small number who has some other reasons and I will not discuss it here). Surprisingly, what they fail to realize is that following too many courses is dangerous and they might end up getting lower grades in all courses (due to the unexpected workload), as opposed to only following the required number and getting good grades. I have been trying for a while now to tell this message to the students and it was most number of times a failure than a success.

Now, the floor is open for discussion :-) ……

Weather Pattern and the Average

These days it’s unbearably hot everywhere in Sri Lanka, even in Peradeniya (it’s 10 in the night and my thermometer reads 30.2 oC ). A few days ago, I was talking to a couple of Environmental Engineers and they said that the weather these days are unpredictable.

Not only that, they also said something else, that strikes me. For example, the current weather pattern is kind of odd. If you take a full year, in the past,  you get rainy days distributed along the year; but now it’s concentrated (and heavy) at a few patches and then you get long hot days like now. An interesting observation is that the average rainfall for the year is still the same! However, the effect of the current situation is really drastic. Even though you get the same average, now you have floods/landslides (due to the heavy rain) and unusual dry seasons.

When I told this to a student of mine, he said, “this is why sir, I don’t believe in GPA (grade point average)“…

The Inter City Express (ICE)

After long time, I traveled by the infamous (http://www.slrfc.org/2009/07/20/the-2001-kandy-ice-disaster-a-look-back) Intercity Express to Colombo and return (from Peradeniya). On my return, after passing Rambukkana, I happened to spend some time sight seeing and couldn’t avoid noticing the sign boards, intended for the engine driver (I suppose). Most of the signs read “15 MPH” (yes, apparently, we still use miles per hours in our railway) and with various reasons in the second line such as “Weak Rail”, “Insufficient metal”, etc.

In the age trains traveling at unimaginable speeds, an ICE, for 1/3 of its distance, traveling at 15MPH, what a disaster? I know what most of you are thinking, welcome to Sri Lanka, a land like no other!  Seriously, we should improve our railway system starting from our railway network, trains and most importantly, the railway stations.

On a non-related topic, our road network is far better than it was like 10 (or even 5) years ago. But, the trains, hmmmm……!

Do I (you) like presentations with stats?

I always wondered about the skills a presenter exhibits and the information (s)he presents that attract people. First of all, it is obvious that a good presentation should be an interesting one. Given that I am a lecturer my profession, I always believed that making an interesting presentation is part of making a good one. One of the factors that catch my (and most of the audiences) interest is the amount of statistics presented there.

As much as I know, coming up with statistics about the subject we present is just a couple of mouse clicks away (in this Internet era), I always was attracted to presentation with lots of statistical information. Even though I know I am going to forget most of those stats in no time, how could they interest me more than anything else?

I am not a Genius!

After listening to a lot of people in different fora (mainly the movies) talk about their IQ levels, I decided to test mine today :) . According to http://www.free-iqtest.net, I am not a genius – obviously!

Conference vs. Journal Publications

Sometimes ago, one of my friends forwarded a link (http://cacm.acm.org/opinion/articles/34492-viewpoint-time-for-computer-science-to-grow-up/fulltext) for an article titled “Time for computer science to grow up“. The author of this article argues against Computer Science related researchers using Conferences for publishing their findings against the preferred option in other fields, the journals. The author argue that Computer Science is no longer a young field to rely only on conferences and it has to use the journal model for publications. Even though I agree with this author in most counts, I am disagreeing his argument for a simple reason – the time take for a publication in a good Computer Science journal.

I, myself a Computer Science researcher (and academic) have many a times thought about it. The research group I was working during my PhD (this is the first time, I started doing some research :) ), at that time was not worried about journal publications. When we have some findings, we go ahead and submit it to a conference, present it and go forward with our work. When I was about to finish my PhD, we decided to write some of my work as journal manuscripts. I in fact have submitted three such papers to journals by the time I completed my PhD.

Even though, the processing time of most of the journals for a manuscript is around 1 year, some famous journals take more than two years to come back to their authors. By that time the work in a field like computer science become outdated. In addition, if a manuscript is rejected, then it takes another round of 2+ painful years for the authors to get it accepted to a good journal.

I still wonder why these so called “good” journals take 2+ years to process a manuscript. I, myself have worked as a reviewer for most of these “good” journals in my area of research and the time given to reviewers  by the editors of these journals are a maximum of 6 weeks. Maybe I will only know the reason when (and if) I become an editor of one of these journals. If the delay is in the processing of finding suitable reviewers, I agree that it is a time consuming and painful process. However, if the delay is just for keeping the papers in a queue, then, I think we should do something about it.

I also have listened to researchers complaining about the bias editors have towards manuscripts from certain institutions or from certain countries. I am not talking about their bias to accept or reject papers, but to process them fast. Jokingly, one of  my good friends and me used to say that each famous research group runs its own journal. I wish it is not true, however, I am not sure! This friend used to say that we should only start writing journal papers, when we have our “own” journal – one for our group (so, obviously we are not that “famous” yet).

Whatever the cause it is, unless this processing delay is rectified, publishing in so called “good” journals is a waiting game for a common researcher – at least in Computer Sciences. Therefore, in my opinion, we should first grow up to solve this problem before growing up to adapt to the culture of publishing in journals.
