Stubbornly Committed to PBG

So, I finally had my Photobase Generator, but lots of questions.

First, why did it seem to release acid upon irradiation? Upon reviewing the paper in which this molecule was synthesized, I discovered that they had published no actual pH data, only that the product had decomposed upon irradiation into two products, one of which was cyclohexylamine, the basic compound. Because cyclohexylamine was released, it had been classified as a photobase generating solution, which made sense. However, 6-nitrocoumarin was another product, and I couldn’t find any record of it’s acidic properties. My assumption was that perhaps the nitrocoumarin was actually more acidic than the cylclohexylamine was basic. Perhaps that would account for the drop of pH. However, quick tests proved that the nitrocoumarin was relatively basic, so that couldn’t be the solution.

The Synthesis Dilemma

I apologize for not posting as much as I probably should, but up to this point, despite a large number of trials and theories, very little overall progress has been made, due to a number of extenuating conditions. Let’s talk.

The Riddle Part 2, and the Trouble with Experiments

A public opinion riddle, part 2:

To explain the 1965 election public opinion shifts, Noelle-Neumann offered a new theory of social influence: the spiral of silence. The catalyst for the phenomenon was the favorable television coverage of the Christian Democrat party during the Queen of England’s state visit to Germany. In the summer of 1965, the Queen of England had embarked on an 18-city tour of the country. This symbolic state visit, which was covered widely on German television networks, undoubtedly served as good publicity for the Christian Democrats. Christian Democratic Chancellor Ludwig Erhard had accompanied the Queen to most sites, and TV broadcasts often showed him appearing with the Queen to greet cheering crowds (Kennamer 1990, Kaid 2007). Noelle-Neumann argued that, amidst this wave of publicity, supporters of the Social Democrats perceived a lack of social support for their party among the German public. They thus began to see themselves as belonging to a distinct “opinion minority” whose political positions were perceived as less legitimate than those of their dominant Christian Democratic opposition. This lack of perceived legitimacy compounded with a universal fear of social isolation to discourage supporters of the Social Democratic platform to publicly disclose their political opinions and voting intentions in the polls leading up to the election.

MidSummer Data Presentation

Well the summer is almost over and today is the day that my research partner and I give data presentations. This will not only help us in determining what each of us has done so far but it will also help begin the rigorous process of data analysis that will culminate with my senior research theses this coming spring. We will also propose what else needs to be done during the school year to really test and pick apart our hypothesis that the Montebello Region of the Blue Ridge is currently in a state of transience.
