Into Unscientific

"Thesis?"

In the office, upon hearing Tian Liangwei's question, Xu Yun showed a rare hesitation on his face.

He was silent for a while, and finally decided to tell the truth:

"Teacher, if there is a chance, I would like to publish an article in the journal of the first district."

"District 1"

Tian Liangwei tapped his index finger on the table, not feeling too surprised, and muttered:

"Xiao Xu, you should know that as a neonicotinoid insecticide, imidacloprid itself has a substance name, but its patent expired in 2011.

So if you want to publish a journal paper in the first district, four generations is definitely not enough, and five generations is the most basic requirement, is that okay? "

Xu Yun nodded slightly, indicating that he understood.

When it comes to papers, the words SCI and nature may pop up in most people's minds.

But in fact, the former and the latter are not a category concept.

SCI, many people will mistakenly think it is the abbreviation of "Science" magazine, but this is actually a mistake!

The full name of SCI is Science Citation Index, which refers to a journal catalog index operated by Clarivate Analytics, not a separate journal.

If a journal enters this index, it means that it has a certain quality. You can go to this website to check whether the target journal is indexed.

Clarivate Analytics also developed an indicator called impact factor based on the citation data of each journal in the past two years.

Taking 1992 as an example, calculate the impact factor of a journal in that year:

X = The total number of papers cited in 1992 by a journal in 1990 and 1991 based on 1992.

Y=The sum of all papers published in a journal in 1990 and 1991 based on 1992.

IF1992 = (X(1990, 1991)/Y(1990, 1991)).

Clarivate Analytics assigns them partitions according to the impact factors of different disciplines. The partitions made by Clarivate Analytics are called JCR partitions.

The impact factor ranks the top 25% of the journals in the corresponding discipline as Q1, the top 26~50% as Q2, and so on.

In addition to Clarivate Analytics, the Chinese Academy of Sciences also divides journals into divisions. The full name of the divisions of the Chinese Academy of Sciences is the "Journal Division Table of the Documentation and Information Center of the Chinese Academy of Sciences", which also divides journals into four divisions.

But it is pyramid-shaped, the first 5% of the journals are in the first district, 6%~20% are in the second district, 21% to 50% are in the third district, and the rest are in the fourth district.

The division of the Chinese Academy of Sciences mainly considers the impact factors, but there are also certain artificial adjustments.

To make an image metaphor:

Posting an SCI can be compared to climbing a mountain. There are many mountains, some high and some low.

The mountains at your door are mountains, the small hills are mountains, the Five Sacred Mountains are mountains, and the Himalayas are also mountains.

SCI journals have many divisions, and these divisions correspond to different mountains. Whether it is difficult to post an SCI article depends mainly on what mountain you want to climb.

The SCIs in the third and fourth districts are probably the mountains that are difficult to climb in small counties or prefecture-level cities, the second districts are some famous mountains in the region, and the first districts are the five mountains, which are majestic and beautiful.

The Nature sub-journal is almost the Himalayas. As for Nature, Cell and Science, it is the well-deserved Mount Everest, also known as CNS.

The above is the detailed relationship between the papers, and .JPG is added for useless knowledge.

At present, most of the divisions of the Chinese Academy of Sciences are commonly used in China, but most people come into contact with the third district, at most the second district.

At the same time, when it comes to papers, I have to say another melon:

The price of essay writing.

Friends who often eat melons on Weibo should know that two major things have happened in the field of papers in the past few years:

One is that a large number of local SCIs have been falsified and skinned, and the other is that after the incident of an actor surnamed Zhai, the plagiarism of papers has become more stringent. As a result, some graduate students can only be forced to publish SCIs to avoid duplication of their own papers.

In addition, the competition in scientific research is becoming more and more fierce, and it is becoming more and more difficult to publish papers. The price of SCI papers is naturally rising.

At present, the price of ghostwriting for domestic core journals is almost 8k, 3w+ for garbage sci with 1 point or a fraction of a point, 6w+ for around 2 points, and more than 100,000 for 3 points or more.

As for those with more than five points, the minimum is 200,000!

So why do you say that some people will start a paper company, because it does make money

The line of sight returns to the original place.

After understanding Xu Yun's goals or aspirations, Tian Liangwei also seriously helped him with his ideas:

"Xiao Xu, if you plan to submit to a regional journal, you must first make it clear that you will definitely not have a chance for the main journals of "Cell" and "Nature". Is that okay?"

Xu Yun nodded and said calmly:

"Understood, the academic value of the fifth-generation imidacloprid is much lower than its commercial value, which I have counted from the beginning."

Hearing this, Tian Liangwei had a satisfied expression on his face. The most important thing to do in academics is to have a clear enough position for yourself:

"In this case, let me recommend a few journals for you, such as "NUCLEIC AIDS RES", "TRENDS IN BIOCHEMICAL SCIENCES", "EMBO JOURNAL" or "CURRENT BIOLOGY".

Xu Yun took a pen and listened while taking notes. After his teacher finished speaking, he drew a horizontal line in the middle of "EMBO JOURNAL":

"Forget about "EMBO JOURNAL". Although it is an old-fashioned journal, it mainly focuses on DNA, which is somewhat inconsistent with protein."

Tian Liangwei didn't say a word, what he gave was just a suggestion, and the final choice should be made by Xu Yun himself.

Then Xu Yun ruled out "TRENDS IN BIOCHEMICAL SCIENCES":

""TRENDS IN BIOCHEMICAL SCIENCES" is good, but the review period is too long, and teacher, I remember that its editor-in-chief seemed to say something bad last year?"

Tian Liangwei was taken aback for a moment, then slapped his head, annoyed:

"Look at my memory, why did I forget about this, I quickly deleted it, and voted for this book, and I guess it will get 404 on the first day it's on the shelves!"

Hearing this, Xu Yun couldn't help but sighed lightly.

In recent years, due to well-known reasons, some academic journals have gradually put on some colored glasses, and the entire international academic environment has also become a bit depressing, and various speeches and even conspiracies against the local people have followed one after another.

You said that some journals do not do good academic work, so why do they get involved in this kind of thing?

Then Xu Yun withdrew his thoughts, and shifted his gaze to the remaining two journals, with hesitation in his eyes:

""CURRENT BIOLOGY" is indeed a good choice, its IF has been rising since 2016, and the review speed is also very fast.

As for this "NUCLEIC AIDS RES" teacher, if I remember correctly, it seems to be a journal for manuscripts? "

Tian Liangwei nodded and said:

"That's right, IF13.8 is highly authoritative and influential, but it is mainly in the form of solicited manuscripts, and only more than 70 articles are published a year.

But Xiao Xu, if you want to select for this journal, I can recommend it to you. "

Xu Yun immediately looked at his teacher with an expression of "You still have overseas relations".

Seeing Xu Yun's surprised gaze, Tian Liangwei raised his chin arrogantly, and took a sip from his teacup tactically:

"It's no surprise, right? Your teacher and I have an H-index of 77. Do you understand the gold content of a biomedical professor's H-factor of 77?

To tell you the truth, when your teacher goes abroad to visit other people's editor-in-chief, he has to pick him up at the airport and accompany him for dinner. "

After showing off a wave of gold content, Tian Liangwei's expression returned to calm:

"I know the editor of "NUCLEIC ACIDS RES" and several external review professors, and one of them is a top scholar of our Chinese community. It is not difficult to request and review manuscripts."

Hearing this, if Xu Yun didn't understand Tian Liangwei's thoughts, he might as well stop reading. After all, the review time for regular papers is too long:

"Then teacher, I will prepare the thesis according to the requirements of "NUCLEIC ACIDS RES"?"

Tian Liangwei nodded and said:

"I personally recommend that you vote for "NUCLEIC AIDS RES". After all, it is easy to handle things with acquaintances. Now you can prepare the papers related to the fourth generation. If you break through the fifth generation, you can directly supplement them on the next page. In this way There is still some effort left."

After explaining the issue of the journal, Tian Liangwei chatted with Xu Yun briefly, and Xu Yun said his farewell tactfully and left.
