They may disagree with the PAP on select issues. Or they may vote for the opposition because the ballot box is the only way to register their feedback. A true picture is unavailable because non-PAP parties are marginalized in the electoral system as shown by the PAP's popular vote (60%) and seats in Parliament (93%) and alternative views cannot enter the decision making process. Even within the PAP, power is centralized at the pinnacle and away from its MPs and even the less privileged echelons of the cabinet.<br /><br />Therefore, what would otherwise be purely technical issues take on a political dimension because of the absence of political participation.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2348464617577736454.post-27107742127897125292013-07-29T09:29:06.080+08:002013-07-29T09:29:06.080+08:00Actually, NEA uses the PM10 standard for the relea...Actually, NEA uses the PM10 standard for the released PSI figures.<br /><br />It does not evaluate air quality based on small particles which are more dangerous, which are evaluated under the PM2.5 standard.<br /><br />http://aqicn.org/faq/2013-06-25/singapore-psi-and-pm25-aqi-why-is-there-a-difference-between-the-two-readings/Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2348464617577736454.post-79973231283816380992013-07-29T08:38:26.692+08:002013-07-29T08:38:26.692+08:00To be fair to NEA, EPA reference and equivalent me...To be fair to NEA, EPA reference and equivalent methods for PM2.5 is by default giving a 24-h average reading. A reference method is the standard method and an equivalent method is just as equivalent.Generally, reference and equivalent methods are all using 24-h sampling. There are of course scientific reasons and studies done to justify a 24-h sampling. If you are really interested, you can ask the PM2.5 instrument manufacturers or look in scientific journals.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2348464617577736454.post-35491083090761626372013-07-28T23:50:49.426+08:002013-07-28T23:50:49.426+08:00Why is it that every discussion online these days ...Why is it that every discussion online these days degenerates into an us vs them, anti gov vs pro gov slinging match.
