A | A nearly 4,000-words long essay published in the peer-reviewed journal Qualitative Research in April has recently attracted quite a bit of attention and scrutiny after going viral on Twitter.,The paper is authored by Karl Andersson, a PhD student at the School of Arts, Languages and Cultures at The University of Manchester, and is titled “I am not alone – we are all alone: Using masturbation as an ethnographic method in research on shota subculture in Japan”, with “shota” being defined by the author himself as a “Japanese genre of self-published erotic comics that features young boy characters.”,“In this research note, I will recount how I set up an experimental method of masturbating to shota comics, and how this participant observation of my own desire not only gave me a more embodied understanding of the topic for my research but also made me think about loneliness and ways to combat it as driving forces of the culture of self-published erotic comics,” Andersson wrote.,According to Vice News, the essay essentially amounts to the description of the author’s “masturbation habits” and thoughts and feelings while reading the comics in question, as well as “defenses of all of the above as legitimate research.”,Lots of generative discussion on this new piece of research at #ASA2022. pic.twitter.com/DZ7bEY9Akq— Tim Gill (@timgill924) August 9, 2022,As the paper got more and more attention online, many sociologists and researchers decried it as “deeply problematic, embarrassing, and even dangerous to the field”, with some even initially suspecting that it was a joke, the media outlet notes.,“While sexuality researchers have written about masturbation, this is the first I have heard of masturbation as a methodology, let alone masturbation to depictions of children,” Andrea Becker, postdoctoral research fellow studying sexual and reproductive health at the University of California, San Francisco, told Vice. “It is a misrepresentation of qualitative work, of sociology, and of sexualities research.”,Justin Gutzwa, a postdoctoral scholar at the University of Utah who researches gender, sexuality, and transphobia in education, also wondered aloud “what was the review process for this article like”.,“I’m mystified that any reviewer would pass off on this as an exemplar of innovative ethnographic methods, let alone an acceptable, appropriate, or ethical piece of writing,” he remarked.,Qualitative Research has announced that they launched an investigation into the publication on 9 August.,The media outlet also points out that Andersson’s fascination with “shota” appears to be well-documented, and that this particular genre is actually illegal in the UK – where he “goes to school” – as well as in several other countries.。

Chinese scientists on Wednesday released the first complete set of observational images captured by China's new-generation ground-based infrared telescope, filling a gap in the country's near-infrared astronomical observation capabilities and reducing reliance on foreign infrared detector technology, China News Service reported on Wednesday.
The 80-centimeter near-infrared telescope was installed at Saishiteng Mountain, Lenghu township, Northwest China's Qinghai Province in October 2024. Jointly developed by Sun Yat-sen University and several partner institutions, the telescope is China's first to achieve scientific imaging in the 1.2-micrometer J band and 2.2-micrometer K band using domestically developed scientific-grade InGaAs and HgCdTe detectors.
The telescope enables unattended remote operations, and can lock onto any target in the sky within 15 seconds. Its infrared capability allows it to see through interstellar dust, enabling it to observe cold and distant celestial objects that are difficult for optical telescopes to capture.
According to Ma Bin, a professor at the School of Physics and Astronomy, Sun Yat-sen University who led the research team that released the infrared telescope's observational images, all three of the telescope's core astronomical observation capabilities were fully validated during operation.
It rapidly responded to and tracked multiple gamma-ray bursts and supernova events, recording the evolution of their infrared afterglows following the explosions. It continuously monitored brown dwarfs, precisely capturing periodic variations in their atmospheric brightness. Using image-stacking technology, it also observed active galaxies billions of light-years away.
Since its deployment in Lenghu, the system has supported infrared observations for more than 10 Chinese research institutions, accumulating valuable experience for the construction of future large-scale infrared telescopes.
Lenghu township, where the world-class astronomical observation base takes shape, is hailed as "the most Mars-like place on the Earth." The astronomical observation base was said to be an astronomical observation site comparable to the top ones in the world by a Nature article published on August 18, 2021, according to the Chinese Academy of Sciences.
Once prospered in 1950s due to its rich petroleum resources, Lenghu is now becoming a premier astronomical observation site and Mars-themed tourist destination, according to Xinhua News Agency.
