Googling myself

I googled myself to get some information for my resume. In the process, I discovered that this site has been indexed by Google and so is its mirror. For some reason I found weird Google ads on my blog, but couldn't find them when performing site administration. Anyway, they are gone now... weird!

More writing samples from me that I never knew existed:

RJC2000PRELIMQ4


“The Internet’s early communalist enthusiasm for open-source software-which is free, unpatented and uncopyrighted- has now given way to a land-grab. Internet companies are rushing to patent their ideas.” The Economist, July 2000


    • a. Explain the likely market structure which economic theory suggests would exist in industries where patents are prevalent. [12]





    • b. To what extent is the above trend bad for the consumer? [13]



Part a


Economic theory suggests that an oligopolistic market is likely to exist in industries where patents are prevalent. An oligopoly is a market structure that falls between a monopoly and a monopolistic market, and it refers to the situation where a market is dominated by a small number of large powerful firms.

Like in the case of internet companies rushing to patent their ideas, the oligopolistic market is characterised by barriers to entry as well as interdependence of firms. Barriers to entry may be natural or artificial. Patents are a form of barriers to entry as they create secrecy of knowledge characteristic of oligopolistic firms producing differentiated products. Patents offer legal protection.

Other barriers to entry include brand loyalty. For example, the established real player and winamp software have a large following and are hyperlinked to many other websites, and thus a new software may need great innovation and first impact to rival the number of downloads these famous names receive.

Also the extensive research and product development may raise already high start up costs in industries where patents are prevalent. For example, the software counter-strike allows internet gaming and LAN games, and has new betas published frequently, and thus other companies will need to have equal, if not better, variety and quality in their software to rival that.

Besides that, in an oligopolistic market structure, products are differentiated, and secrecy is generally maintained. Generally, non-price competition is adopted and supernormal profit is made. For example, internet companies like SingNet and Pacific Internet have long avoided price competition, until StarHub introduced free access. Pacific Internet decides to attract eyeball s to avoid direct price competition.

An important characteristic of an oligopoly, here patents are prevalent, is the interdependence of firms. This may well lead to the formation of a formal collusion (a cartel e.g. Organisation of petroleum exporting countries OPEC) or a tacit collusion. Firms tend to adopt similar pricing, advertising and marketing strategies. For instance, both winamp and real player offer a free download with the option of purchasing a better full version of its product online. Due to tacit collusion, firms are likely to base prices on barometric firm price leadership – following the most representative firm at a particular point in time, or base prices on dominant firm price leadership – i.e. a firm that has the greatest influence sets the price and all others follow.

In an oligopoly there exists price stickiness, which may be explained by a kinked demand curve, showing that if a firm raises its prices, then other firms are not likely to follow but if prices fall then other firms are likely to follow suit. However, this does not explain why the kink occurs or why the initial price was determined such. The costs of updating the WebPages etc. and other menu costs incurred may explain price stickiness.

Part b


To some extent, the evolution of the internet into an oligopolistic market is bad for the consumer. First, an oligopolistic market relies heavily on advertising in a bid to avoid non-price competition. Advertising in itself may be a form of directly unproductive activity, and therefore is a misallocation of resources. Furthermore, advertising may be a form of irritant to consumers. For instance, pop-up advertisements that appear when one accesses a certain website. Advertising costs may be passed on to consumers indirectly too.

Second, the rise of oligopolies in an internet market where patents are prevalent may lead to the presence of X-inefficiency such as a breakdowns in a Hotmail account etc. X-inefficiency arises when the firm gets bigger.

Third, this above trend may increase the difficulty of new firms breaking into the market due to the higher fixed costs, the patented designs and so on. For instance, a young entrepreneur may find it expensive to start a new internet firm and patent his designs, when his competitors may include Netscape and Microsoft. Thus, innovation is limited and consumers may lose new choices.

However, this trend of moving towards an oligopolistic internet market may not be entirely bad, for instance, large oligopolistic firms earning supernormal profits will have funds for research and development to upgrade their existing products, and these improvements in product quality will be passed on to consumers.

Also, oligopolies provide a range of differentiated products for consumers to choose from. For example, one may choose a Netscape or Internet Explorer browser and equip it with a variety of other supporting software such as macromedia etc.

Third, oligopolies earn supernormal profits and the copyrights and popularity of existing firms may encourage entrepreneurial spirit t break into these contestable markets. For example, the establishment of meshworkz was encouraged by the boom of internet gaming and the underutilisation of internet gaming capabilities. Such new firms will benefit consumers by providing them with greater variety of choices.

However, considering that the oligopolistic market is potentially allocatively inefficient as price may exceed marginal cost, thus creaming off consumer surplus and leading to welfare loss, it may be seen that the trend of internet companies rushing to patent their ideas is no perfect blessing. An oligopolistic market, like any other market structure, has its good and bad.

Notes on DISC

I am a high DC, which explains why I do not like having no options. When dealing with a D-student, give them options, even when the final outcome is likely to be the same as what you have predetermined.

For instance, instead of, "We are going to work on this topic," say, "We have a list of topics, and this is the one that the majority have chosen to work on."

Education Studies Elective

This is the one I am interested in. I quote from the Jan 2008 PGDE(S) Handbook:
QED581 Differentiating Instruction for Able Learners
The promise of an ability-driven curriculum and that all students will learn is mere rhetoric if teachers lack deep knowledge of learners and the pedagogical skills necessary to help learners of diverse abilities. There is a need to help teachers better understand the traits and needs of high-ability learners and to make needs-based curricular modifications and
instructional decisions in mixed-ability settings. This course aims to help student teachers develop an overview of the conceptions of giftedness,
understand the psychology and needs of the precocious student and develop appropriate, differentiated approaches to meet the learning needs
of these students in mainstream classrooms.

My other choices, in order of preference, are:
QED560 Computer Supported Collaborative Learning (CSCL)
QED576 Developing Creativity in the Secondary Classroom
QED582 Teaching Students with Behavioural and Learning Problems

Is It Okay To Be A Technologically Illiterate Teacher?

Read the full post here. This is the winner of the most influential post at the 2007 Edublog Awards. One of his key arguments is that it does not matter if you are a digital native or immigrant - you must be technologically literate to teach.

Pedagogy of the Oppressed

Pedagogy of the Oppressed

Strongly recommended by my NIE senior and NUS peer, especially for those who will be going to neighbourhood schools, and who may be interested in other uses of drama in teaching.

Giftedness

Taken from Wikipedia:
Generally, gifted individuals learn more quickly, deeply, and broadly
than their peers. Gifted children may learn to read early and operate
at the same level as normal children who are significantly older. The
gifted tend to demonstrate high reasoning ability, creativity,
curiosity, a large vocabulary,
and an excellent memory. They often can master concepts with few
repetitions. They may also be physically and emotionally sensitive, perfectionistic, and may frequently question authority.
Some have trouble relating to or communicating with their peers because
of disparities in vocabulary size (especially in the early years),
personality, and interests. As children, they may prefer the company of
older children or adults.

Reflection on the course that has concluded, but not the last you’d hear from me

Form-filling...

SCLP-related

What were some major changes to my SCLP?

The removal of our introductory video and changes to our web header image.

Why did those changes take place?

To prevent ourselves from inadvertently distributing copyrighted material.

How did I contribute to my group's SCLP?

Some project ideas. Did the website (using edublogs' templates) and its header (using GIMP), the spliced introductory video and the titles on the demonstration video (using misbehaving Windows Movie Maker), flubbed role-play in one-half of the demo, the links and anchors on the pages... and I forgot or rather never bothered to test our page on Internet Explorer all this while! The change has been made on our online site for progeny... but in line with my personal policy, all pages, SCLP or not, should be best viewed in Firefox. Get IE tab to resolve IE/FF conflicts.

What did I learn as a result of creating an SCLP?

I revisited  Scrapbook with joy. Actually, Guilian did help clarify a lot of my ideas on scaffolding and the assessment process. So yes, I think one of the strengths of our SCLP is the excellent scaffolding. Yay. And of course, lots of practice with Google Docs, GIMP, html and pretending to be a student.

What did I learn from QED522? (What was the first thing that popped into my mind?)

I've wanted to raise this question for sometime now... but I always thought Dr. Black was the one killed, and Colonel Mustard... he's just one of the usual suspects.

Student-centered learning will not kill the teacher. I actually think it gives teachers more room to play and students more motivation to learn. From the mercenary point of view, I have learned pedagogical approaches and received/created opportunities to polish rusty ICT skills, so my list of skills has expanded.

I  am still thinking unashamedly about free laptops...

Almost final, plus a note on valedictorians

It's almost the day of submission and I feel compelled to write a redundant post to remind myself of things that need to be wrapped up.

  1. Capture my SCLP with a depth of 2, so that comments on "student" blogs will be saved as well for offline viewing.

  2. Export the captured SCLP package to another directory for checks before burning it onto a disc.

  3. Finish up our final storyboard on GIMP.

  4. Export our lesson plan and clean it up for burning.

  5. BURN!


I just checked the results of the NIE Valedictorian poll... a grand total of 45 votes were cast, making the outcome very representative, but the graduating cohort will have their valedictorians no less. The tribe has spoken, kind of. It just makes me doubt increasingly how well online polls that carry no perceivable benefit for the voter can work. Behavior modification does take some time and study to function in full bloom.

Maybe it’s good to sell fish once in a while?

This post has nothing to do with selling fish, actually, but I figured that it will probably have a total readership of about 3-4 people. Enough of the idiosyncratic crap that I think I understand.
How to export a web-based SCLP for offline viewing in your browser (instead of printing everything to PDF for further painstaking annotation) - my way:

  1. You must have Mozilla Firefox installed. (Switch if you are using IE.)

  2. Find and install a lovely extension called Scrapbook. Restart FF to complete installation.

  3. Go to the homepage of your web-based SCLP, then right-mouse-click, "Capture Page as..."

  4. To capture not just the page you are on but also the pages that it links to, and the pages those pages link to, you need to select a Capture Depth of at least 1.

  5. Wait for it to save, grab a Kit Kat, have a coffee, or go for a toilet break.

  6. Check your Scrapbook folder for the saved package. If saved correctly, the links will be relative, so they should work offline as they do online.

  7. Smile to yourself, use Scrapbook to annotate the saved pages if you like, then burn a copy for submission.


*NEW* Additional instructions to myself:

  • Give the folder an English name.

  • Locate the file named "index" to start browsing offline.
