Average Salaries in the Chaebols
Here is a chart from the Korea Herald showing the average salary of the workers in the chaebols [l] in millions of won per year:
Note: 1 million won is about 850\$US or 1100\$CAD.
Mapping Tree Density at a Global Scale
An article entitled “Mapping Tree Density at a Global Scale” appeared in the journal “Nature” this month discussing the tree density worldwide [l]. One figure showing tree density is striking:
In the latter, the white dots represent areas with year-round ice cover, the brown dots represent areas with no trees, while the dark green dots represent areas with the highest tree concentration. The land proportion composed of areas with little or no trees is alarmingly large — about half of the world's forests have been destroyed or irremediably damaged since the advent of agriculture 10000 years ago. But what is more worrisome is that half of this destruction took place in the last 50 years.. Still today, it seems we haven't learned our lesson: we continue to cut down more trees than we plant as we have been doing for generations. If we do not change our living habits soon and start caring for our environment, the entire planet will be treeless within a couple of centuries.
Map of Flights in Real Time
Here is an interesting website for the aerospace aficionados: [l] provides real time display of flights on a map everywhere around the world.
World Business Culture
The website [l] gives information on how local culture can affect meetings, communication styles, management styles, etc. This can be useful in understanding foreign cultures obviously but also in not making a faux pas when visiting foreign firms/universities or when collaborating with them. The information seems spot on, at least regarding the countries I have experienced firsthand (Japan, South Korea, Canada, U.S.).
Steve Jobs Commencement Speech: Linking the Dots
Yesterday was graduation day at Pusan National University, and this reminded me of an inspiring commencement speech I had seen on youtube a while back.
One part that I particularly liked is the one about “linking the dots”, with the dots referring to ideas or concepts. Many ideas we get, many papers we publish as researchers may seem useless at first. But often, the breakthroughs that are useful to society come from linking together these seemingly useless concepts. Sadly, linking the dots is becoming rarer these days in university environments. Less and less focus is now given to long-term basic research (i.e. the seemingly “useless” research) and more and more emphasis is given to short-term research with immediate applications. Ironically, putting emphasis on research that is immediately useful prevents more useful breakthroughs from occurring..

Inequality in Hiring Process
A recent study shows that graduates from the creme de la creme universities have a much easier time finding a job in academia than those in slightly lower ranked institutions:
The Authors argue that this can not be due simply to the students at the top universities being more talented and/or more productive. Rather, they demonstrate that the hiring process in universities is not meritocratic but largely based on social class: the “class” to which we belong to (as determined by our present and past affiliations), rather than our accomplishments, is often the dominant factor that leads to job offers in the academia.
“Blind hiring” causes stir among Korea’s top ranks
A month has passed since the government announced a plan to implement a so-called blind hiring system that removes job applicants’ personal information, including the name of the university they attended, their place of birth and other credentials unrelated to the job from their applications, but groups who believe they’ll be losers in the process, such as graduates of the country’s prestigious colleges, are crying foul over the plan...

The Lewis Model — Cultural Differences Worldwide
The Lewis model was proposed by Richard Lewis in “When Cultures Collide” (1996) as a means to clarify cultural differences between countries. The Lewis model identifies three dominant cultural traits: reactive, linear-active, and multi-active:
Talks half the timeTalks most of the timeListens most of the time
Does one thing at a timeDoes several things at onceReacts to partner's action
Plans ahead step by stepPlans grand outline onlyLooks at general principles
Polite but directEmotionalPolite, indirect
Partly conceals feelingsDisplays feelingsConceals feelings
Confronts with logicConfronts emotionallyNever confronts
Dislikes losing faceHas good excusesMust not lose face
Rarely interruptsOften interruptsDoesn't interrupt
Job-orientedPeople-orientedVery people-oriented
Sticks to factsFeelings before factsStatements over promises
Truth before diplomacyFlexible truthDiplomacy over truth
Sometimes impatientImpatientPatient
Limited body languageUnlimited body languageSubtle body language
Respects officialdomSeeks out key personUses connection
Separates the social and professionalMixes the social and professionalConnects the social and professional
The culture of each country is then represented as a mix of the latter three traits:

The latter reflects the dominant culture within each country. However, independently of the country, engineers tend to be linear-active, sales people multi-active, and lawyers & medical doctors reactive. Read more here: ... behaviour/

Basic Linear Algebra Subprograms (BLAS)
The Basic Linear Algebra Subprograms (BLAS) library is a specification that prescribes a set of low-level routines for performing common linear algebra operations such as vector addition, scalar multiplication, dot products, linear combinations, and matrix multiplication. Many numerical software applications use BLAS-compatible libraries to do linear algebra computations, including Armadillo, LAPACK, LINPACK, GNU Octave, Mathematica, MATLAB, NumPy, R, and Julia. ... ubprograms
