National Taiwan University (NTU) yesterday released stage-two investigation results on an academic fraud scandal involving professor Kuo Min-liang (郭明良), which saw the university move to fire Kuo and professor Chang Cheng-chi (張正琪), while clearing NTU president Yang Pan-chyr (楊泮池), who cowrote four problematic papers published by Kuo’s team.
Two internal investigation teams and an investigation committee comprising members from outside the institution found that Kuo’s research team presented a host of misleading images in six papers, of which two have been retracted by science journals Nature Cell Biology and the Journal of Biological Chemistry.
The sheer number of problematic images was proof that Kuo “purposefully” added them to the papers, the report said.

The problems manifested in 2006, when Kuo — as the papers’ corresponding author — was responsible for supervising research work, but he chose to neglect the issue and involved a number of his graduate, doctoral and postdoctoral researchers in the presentation of more errors, it said.
The university decided to dismiss Kuo, who should assume “the greatest and ultimate responsibility,” it said.
Chang, whose name was absent from the first-stage investigation results, duplicated and improperly edited several images in four papers, including the 2008 article, of which she was the lead author, the investigation found.
She has been disqualified as a professor, dismissed, barred from re-applying for a teaching position at the university for five years and prohibited from requesting research grants from the school for five years.
Yang, who coauthored four problematic papers, “bears no responsibility” for the falsified data presented in the papers and therefore “has no reason to resign,” the university said.
In a 19-page report, the committee said Yang only provided some general advice on the direction of the research and his clinical insights on the four papers.
Yang’s involvement was limited to the parts he contributed and coauthors were responsible for checking their contributions to the paper, the committee said.
“By a vote of six to zero, our committee concluded that, based on Ministry of Science and Technology regulations, Dr Yang bears no responsibility for the manipulated figures that mainly involve immunoblots,” the committee said.
One of the questions the committee said it assessed was whether Yang should resign in the way former Minister of Education Chiang Wei-ling (蔣偉寧) did over an academic misconduct scandal 2014.
The question has been raised by educators who called for Yang to step down.
Chiang was unknowingly listed by his former student Chen Cheng-wu (陳震武) as a coauthor in a fake online peer review ring Chen helped create in an attempt to have work published by international journals.
Yang’s case fundamentally differs from the earlier case in the nature and the magnitude of the offense, the committee said.
“Therefore, we feel that it is inappropriate to suggest that, based on this earlier case, President Yang should resign,” it said.
A subsidiary of a Hong Kong-based company that has lost control of two critical ports on the Panama Canal said it is seeking US$2 billion of compensation in damages from Panama over its “illegal” takeover of the ports. Panama Ports Co, a unit of Hong Kong’s CK Hutchison Holdings (長江和記實業), on Friday said in a statement that it is demanding the sum under international arbitration proceedings that it had already started. The Panamanian government last week seized control of the Balboa and Cristobal ports on each end of the Panama Canal, after the country’s Supreme Court declared earlier that a concession allowing
DETERRENCE: With 1,000 indigenous Hsiung Feng II and III missiles and 400 Harpoon missiles, the nation would boast the highest anti-ship missile density in the world With Taiwan wrapping up mass production of Hsiung Feng II and III missiles by December and an influx of Harpoon missiles from the US, Taiwan would have the highest density of anti-ship missiles in the world, a source said yesterday. Taiwan is to wrap up mass production of the indigenous anti-ship missiles by the end of year, as the Chungshan Institute of Science and Technology has been meeting production targets ahead of schedule, a defense official with knowledge of the matter said. Combined with the 400 Harpoon anti-ship missiles Taiwan expects to receive from the US by 2028, the nation would have
POSSIBILITIES EMERGE: With Taiwan’s victory and Japan’s narrow win over Australia, Taiwan now have a chance to advance if South Korea also beat the Aussies Taiwan has high hopes that the national baseball team would advance to the World Baseball Classic (WBC) quarter-finals after clinching a crucial 5-4 victory over South Korea in a nail-biting extra-inning game at the Tokyo Dome yesterday. Boosted by three home runs — two solo shots by Yu Chang (張育成) and Cheng Tsung-che (鄭宗哲) and a two-run homer by Stuart Fairchild — the triumph gave Taiwan a much-needed second victory in the five-team Pool C, where only the top two finishers would advance to the knockout stage in Miami, Florida. Entering extra innings with the game tied at four apiece, Taiwan scored
MISSION OF PEACE: The foreign minister urged Beijing to respect Taiwan’s existence as an independent nation, and work together to ensure peace and stability in the region Minister of Foreign Affairs Lin Chia-lung (林佳龍) yesterday rejected Chinese Minister of Foreign Affairs Wang Yi’s (王毅) comments about Taiwan, criticizing China as a “troublemaker” in the international community and a disruptor of cross-strait peace. Speaking at a news conference on the sidelines of the Chinese National People’s Congress, Wang said that Taiwan has always been a territory of China and that it would be impossible for it to become its own country. The “return” of Taiwan to China was the natural outcome of the Chinese people’s resistance against Japan in World War II, and that any pursuit of independence was “doomed
