Final Update

Hi everyone,

I had a lot of fun this summer doing research here and am glad to say that I will be continuing to work on the same project for the upcoming semester. I still have a lot of data to collect and many more qPCR reactions to run, but I’m glad to see how much progress I’ve made over the summer. It has put me in a good position to finish collecting the data and finish up my analysis hopefully by the end of the fall semester so that I can move on to a new project in the spring.

1,5-Benzodiazepine Educational Synthesis – Conclusion

Good afternoon, everyone!

After nearly eight weeks of literature research and experimenting in the lab, I have finalized my initial procedure for the synthesis of 2,2,4-trimethyl-2,3-dihydro-1H-1,5-benzodiazepine using ortho-Phenlenediamine, an excess of acetone, and sulfamic acid catalyst.  I made several alterations to the skeletal procedure by Fletcher given to me by Prof. Lashley, including an increase in reaction time (from 30 minutes to 60 minutes), an increase in catalyst (from 10% molar to 20% molar), the use of reagent-grade acetone (instead of solvent-grade), the use of magnesium sulfate drying agent (instead of sodium sulfate drying agent), the use of a drying column to eliminate atmospheric water from entering the system, and limiting the extraction solvent to 30 mL of DCM (instead of 50 mL).  With these changes, the reaction yields more pure product, in a timely fashion.

The problem of the Han-minority education achievement gap can be explained in three different ways. The ethnic minority groups are also economically disadvantaged and are largely located in rural parts of China. Thus the education achievement gap between Han students and ethnic minority students is also the education achievement gap between city students and rural countryside students. There are also the cultural conflicts between the Han and the ethnic minority groups. As this conflict is largely politicized, the voices of some minority groups are suppressed.

Continued Observations in Tibet


During my interview with the Tibetan officials, I was able to acquire their work reports that are not open to the general public. Combined with my interviews with students and officials, I was able to gain a more holistic understanding of government’s projects in Tibet.

Observations in Tibet

I planned to do my interviews in Sichuan Province, but due to the pressures from local governments officials and the flood in the Yi region, I had to choose a new research site. The new spot I picked up was Lhasa. The situation faced by the Tibetan people are really similar to that faced by the Yi people. Both are ethnic minority groups in China, and both had their own written language and religion. Furthermore, both groups are located in rural and less developed regions in China.
