  1. It was a failed joint venture. Note that the link was hosted by a website design company as an example of its work, and the actual URL www.beckerviolin.com does not have anything.
  2. Thank you, I see what you meant. The effect of quartet-taste confounder may not be correctly identified in this small setting though (only three jurors). For instance, the quartet membership cannot be separately identified from, say, tone judge experience, with Oliviera being a much more experienced tone judge than the two quartet players. So the differences between the soloist's and the quartet players' scores may be due to experience rather than taste. To some extent, gender is also confounded with the membership in this case. More interesting analysis can be done if we have data on multiple contests where different sets of judges were employed. If we want to have a serious analysis, I am not sure what kind of model we could use. What is the outcome/dependent variable? It can't be the total score of a violin since it is just a sum of the jurors' scores. Ideally, if we have data on the characteristics of the violin tone: warm, bright, or even the violin's various modes, then we can see how a certain judge prefers certain types of tones. (BTW, ANCOVA cannot be helpful here because of the required distribution assumption.) I agree. No matter how I attempted to generalize the choice/taste between the soloist vs. the quarter players using the data, I could always find angles to contradict.
  3. Yes, I am aware of their status. However, their opinions/scores are equally weighted in the competition, so I could not see how the analysis can or should be done differently. Suggestions are welcome. On the other hand, could readers identify the soloist from the analysis (or the soloist vs. the quartet players)? I think this is an interesting question. From the hindsight, I think this is not difficult.
  4. Since there has been much talk on the result of tone award of this year’s VSA competition, I decided to do a simple analysis based on the jurors’ scores. The Violin Tone score sheet obtained here contains the three jurors’ scores in the first round (preliminary run) and the second run (evaluation run). No scores are available for the third round (medal run); I guess no one entered the medal run. I want to show two things in the analysis: (1) The extent of score similarity between the jurors (using results of round 2). (2) The juror’s scoring consistency between the two rounds. Instead of naming names, I’ll use Juror1, Juror2, and Juror3 instead. I dropped observations to which the status is not marked as “CLEAR”, and dropped one additional observation for which one of the jurors did not give mark (recused him/herself, perhaps). As a result, there are 192 observations/violins on the first round, and 51 on the 2nd run. Part I: To show the extent of score similarity between the jurors, I produce tables of frequency counts between pairs of jurors, using results of the 2nd run evaluation. Note that only scores of 1, 2, and 3 are given in the 2nd run. In the first panel of the graph below, the figure “17” indicates that 17 violins received score=1 from both Juror1 and Juror2. The figure “5” indicates that 5 violins received score=3 from Juror1 and score=2 from Juror2. Some observations: (1) Juror1 and Juror2 each pick 8 and 9 violins, respectively, to confer their highest mark (score=3). Juror3, however, only offered 2 violins the credit. Could the stinginess of Juror3 contribute to the low number of tone award this year? (2) The similarity between Juror1’s and Juror2’s scores appears to be the lowest among the pairs. Note also that Juror2 gave score=3 to 9 violins, but 8 of them received only score=1 from Juror1. The difference in taste is not so drastic between other pairs of jurors. Part II: To show the juror’s consistency between the two rounds, I counted the number of cases in which a juror gave score=0 to a violin in the 1st round (not recommended to advance) but then gave the same violin score=2 or score=3 in the 2nd round. These are the cases of inconsistency because, had the juror been consistent, the violin s/he didn’t like in the first round (score=0) should have received from him/her the lowest possible score (score=1) in the 2nd round. Here is the result: Among the 51 violins that entered the 2nd round, Juror1 has only 1 case of inconsistency (1.96%), Juror2 has 7 cases (13.73%), and Juror3 has 2 cases (3.92%) of inconsistency. ----- Edit: The following is an improved version of calculating the inconsistency rate. ---------------- For the 51 violins that entered the 2nd round, Juror1 gave 6 of them score=0 in the first round and subsequently gave 1 of them score>1 in the 2nd round. The inconsistency rate is 1/6 = 16%. Juror2 gave 19 out of the 51 violins score=0 in the first round and then gave 7 of them score>1 in the 2nd round. The inconsistency rate is 7/19=37%. Juror3 gave 9 out of the 51 violins score=0 in the first round and then gave 2 of them score>1 in the 2nd round. The inconsistency rate is 2/9=22%. ----------------------------------------------------------------------------------------- What's your take?
  5. A lot of cheap Chinese violins are varnished using what the local calls cashew lacquer (not sure whether this is a correct translation). It is made from cashew, together with phenol, methanol, and tung oil (according to some information in Mandarin).
  6. You once again amazed me. "(L)aws were and have been similar in both, regarding practice of religion"; this cannot be further away from the truth. I googled "taiwan religion freedom" (no quotes) and the first entry is this page: https://en.wikipedia.org/wiki/Freedom_of_religion_in_Taiwan . Part of the page read as the follows. Restrictions on religious freedom Taiwan's policies and practices contribute to the generally free practice of religion. There are no reports of religious prisoners or detainees in Taiwan. Forced religious conversion There are no reports of forced religious conversion. "Christians are still persecuted in Taiwan although a recent BBC story said the situation might be improving". I'll be very interested in reading this report, if it exists. Please, enlighten me. (BTW, my wife is a christian [i'm not] and she is now in the Sunday morning church. Should I be worried that she'll not be coming back for lunch?)
  7. What? Taiwan is controlled by a totalitarian government and there is religious persecution and oppression? Clearly you have no clue. Do some "basic" homework before you criticizing countries "in that region of the world". Regarding the stiletto church, there is a lot of controversy and many locals are baffled as well. According to the builder, the church is to pay tribute to young ladies whose legs were amputated due to the blackfoot disease. They never had a chance to wear stilettos. The blackfoot disease was serious in the late 1950s in the neighboring towns where the church is currently built. Christian churches and hospitals play important roles, especially in the beginning, in helping to combat the disease.
  8. Thanks to those who have replied. It seems that we are still not sure what the glue really is. It's unlikely to be the "washable school glue", Jim, as it would not be called a "special type of glue" . Jezzupe, the sentiment is exactly the reason I started the thread -- I thought the Nippon foundation would be interested in knowing the type of glue he is using. Dwight, I used the AcoustaGrip shoulder rest occassionally and didn't notice any adverse effect on the varnish of my violin.
  9. At 16:10 of this video (it's great), Ray Chen showed that his bar-shaped shoulder rest was attached to his 1715 Strad using some kind of glue. Judging from the magnet-like action of the attachment, I thought the glue must be very strong (i.e., unlike the suction-cup type of "glue" used by AcoustaGrip). Ray said that it is a special type of glue that does not harm the varnish. Does anyone know what kind of glue is that? Henry
  10. The fee is charged by the publisher, not the author. The publisher charges each article for a fee if you are not a subscriber. Authors of the articles get nothing, and for some journals they even have to pay a fee to get their papers published. This sounds weird, but it is a result of demand and supply in academic journal publications.
  11. Then you have to find the supplementary material and read it. Here is the link: http://rspa.royalsocietypublishing.org/content/royprsa/suppl/2015/02/11/rspa.2014.0905.DC1/rspa20140905supp1.pdf Read in particular "Section 5. Data collection". Alleging data forgery is a very serious acusation. If the acusation truns out to be true, it will literally end the academic careers of the authors. I can't think of any reason to risk one's career over violin's f holes.
  12. Errata: "European diploma" should be "European education background", and that sentence could mean a lack of proper diploma on Lim's part. Still a silly and unfortunate decision on the government's part.
  13. The following is based on the Wiki page of Lim. http://zh.wikipedia.org/wiki/%E6%9E%97%E5%85%8B%E6%98%8C He was born in 1928, had a first violin lesson with his father, then studied with Ivan Fedoroff in Jakarta. After the WWII, he went to Conservatorium van Amsterdam to study with Jos de Clerck who is said to be a second-generation pupil of Ysaÿe. In 1950, he went to Conservatoire national supérieur de musique et de danse de Paris and took private lessons from Enescu. He is no doubt a noted and well-respected conductor and violin pedagogue in the Chinese community, but his education background is not without controversy. He was forced to "retire" from (now named) Taipei National University of the Arts in 1992 after working there for one year. The reason cited was that his European diploma was not formally recognized by the Education Ministry of Taiwan.

    He took them from the following site, as he always does. http://bbs.cnstrad.com/thread-15978-1-1.html
  15. Google ebay seller "old violin house", and you'll see many Chinese violin bows of the similar quality.
