I used a commercial tool created by a small company to perform quantitative analysis of medical images for a study that I did. I was very conservative in my statistical analysis and consulted with a university-employed biostatistician throughout the process. The results were negative. I presented the results at a conference and have submitted the paper to a journal where it is currently under review.
The problem is that the founder of the company whose tool I used came up to me after the presentation and started to interpret my results differently, putting them in a more positive and hopeful light. He is an engineer and is, of course, highly knowledgeable about the tool we used since he developed it. However, he wants to help us re-analyze the data since he ‘saw some interesting results’ in my presentation. I feel uncomfortable about this since I believe there is a conflict of interest at play if we were to work directly with him. I think he has a clear economic incentive to promote his analysis tool, and I can see how the results of our study might influence the perception of his product.
Am I overthinking this situation? What level of cooperation with this person would be acceptable from a COI perspective?
My situation is similar to but not same as –UG different field than phd
Please skip to edit 2 below if you want to know the problem in short.
Talking of my career so far,
- I completed undergraduate in CS(computer-science) with WSN (wireless-sensor-networks) as thesis topic (Networks)
- Joined an MNC(multi-national-company) in Android GPS team and stayed for a year (More Networks! )
- Completed masters in CS with Social Network Analysis as main thesis. At this point I got interested in ML (machine-learning), NLP(natural-language-processing) and during my entire program I took related courses.
- Joined another MNC 11 months back, in their router OS QOS (quality-of-service) team (Networks again! )
I now want to apply for a PhD in ML / NLP from colleges like Carnegie Melon or N NUS, Singapore. But I find I don’t have enough recommendation/ work experience in the same field.
What should I do – Personal projects in these areas? Personal publication? Working with a startup in these fields ?
Kindof desparate now to prepare and apply for some program within the next year.
I know its difficult to suggest something that will definitely work in my case but still wanted some advice from the community.
Edit:- Expanding on the acronyms as suggested in comments. Sorry for the long background but I wanted others to understand my situation by stating “some” of my backgound.
Edit 2 : –
Editing this again to highlight my problem in short. I want to pursue phd in fields(ML, NLP) in which I have somewhat less experience. My GPA is not extraordinary for an international student and have only single recommendation in the same. I do have a publication but not related to these areas. Any suggestions for getting my CV to be accepted by any faculty in ivory colleges?
This question is related to: How to sort search results from SCOPUS or Web of Knowledge by number of citation in a specific field?
but a little bit different.
Is there a citation manager that keeps number of citations current for articles that are found in common databases? I have looked at popular ones like Mendeley, ReadCube, and others but haven’t seen this feature.
I think that if number of citations was a field in a manager database, it would probably be easily sortable.
The impact factor (and other indicators of citations per document per year) is often used (controversially) to evaluate the research impact of a journal.
Critics of the impact factor often point out that it based on a skewed distribution with outliers. For example, many papers may have zero citations, another set may have a small number of citations, and finally a small set of papers may have a large number of citations (e.g., 50 or 100, etc.).
In general, I’ve read that this profile is typical of many mid-tier journals.
Thus, this is used to suggest that the impact factor may be influenced by outliers.
I agree that this distribution of citations does highlight that the impact factor overestimates the median citations per paper (as is the case with any positively skewed count distribution).
But another critique is that the impact factor is unreliable because of this distribution.
Thus, my question is:
What formula can be used to calculate standard error of the impact factor for a journal?
Presumably, this would help both critics and advocates of the impact factor to be able to quantify the uncertainty in estimating the impact factor. It would also assist in assessing whether it is appropriate to say that the differences in impact factor over time or between journals are a reliable difference.
- The standard error of the mean is commonly estimated as: s / sqrt(n), where s is the standard deviation of citations per article, and n is the number of citable articles. So presumably, the main factor that would reduce the standard error would be the number of citable articles published in the journal over the period. But unless we have the raw data, we wont have the standard deviation and the skewed distribution might lead this formula to underestimate the standard error.
- Use existing literature to determine the distribution of citations over articles. Hopefully, its a distribution that can be approximate by knowing only the mean, or where the mean provides a good estimate of the standard deviation
- Then apply a formula to get the standard error of the impact factor.
A third co-author C of a study in 2016 available on-line (under subscription) want to re-use the data (included in the figures or tables) of this paper with for others co-authors (A, B, D, E). Co-authors C and A are in conflict.These data will be presented and analyzed in a different manner to support its own and new data set in a paper that Co-author C want to submit as unique author. Co-author C will only use the published data (and not the raw data) of the study of 2010. Some raw data are available on-line (under subscription). However, co-author C only collected but not processed an insignificant part these data. After asking the editor permission that co-author C have (he is limited to re-use only 3 tables or figures), do co-author C has the right to publish part of theses data in a new paper as a unique author? these data are considered to represent (30%) of the data set for the new paper. Does the co-author C has the right to re-use the data without permission of the others co-authors (A, B, D, E)? The same may be also applied to the raw data already published as supporting data? IS the co-author C allowed to include in “material and method ” or in “results” section some brief sentences describing how he gets the some of these data and these previous results in its new paper as unique author?
The PI request to include all the co-authors (A, B, D, E) for the new publication of co-author C. Co-author C is not agreed as most of the co-authors (A, B, D, E) did not participate in the elaboration, analyze and writing task of the new paper.
My regression tables have coefficient estimates, standard errors, and significance stars indicating the range of p-values (e.g. two stars means p < 0.05).
A reviewer wants the exact p-values. I personally think it would make the table more cluttered than it already is, and I have 12 regression tables.
Should I adopt the reviewer’s suggestion, simply because they are the ones who will play a big role in determining whether my paper is accepted? Or should I attempt to explain, saying that the p-value can be calculated from the coefficient estimates and standard errors (besides, the significance stars already give a good guide to the p-value?)
I have submitted a paper to a peer-reviewed journal. On the first round of review, 3 reviewers had different comments and I tried my best to answer them. On the second round of review, two of them were almost satisfied but the third one had an aggressive tone and asked some questions that were completely answered in the paper or were basically wrong questions.
I answered the reviewer’s comments and sent the paper, but one of my friends told me that it was better to ask the editor-in-chief to change the reviewer. I want to know, is that possible? How?
In a manuscript recently accepted to a journal, I just realized I neglected to mention that I centered a variable for an analysis. How crucial is this detail to correct, and what’s the best way to go about doing it?
I am a math postdoc in Europe, and have been a postdoc for the last 6 years. Unfortunetly, I was still not able to obtain a tenure track position
(I was very close to get one, but because of bad luck will have to try again next year).
My current postdoc position ends in a few months. Because I thought that I will get a tenure-track position this year, I did not bother to search for a new post doc position until very late in the year. As a result, in a few months I will not have a postdoc position.
My Phd advisor came to the rescue – He can fund me as a postdoc at the University I did my phd in.
I would like to ask if people will look bad on someone that goes do a postdoc with his advisor in future job searches?
I should mention that I did not work with my advisor at all after my Phd, and am very independent in my research. Still, I am worried about this, and wonder what people think about such a situation.
I have over 13 years of experience in IT industry, but no consistent domain / specialization. I have worked as UI developer, project manager, scrum master, business analyst, recruiter, etc. for few years each. Now my career seems stuck and I am not getting further on the career ladder.
I couldn’t go to college due to financial constraint in my early years. I am 35 now, but the itch to attend a regular university is still there. I want to do a regular MBA (preferably 1 year) from a foreign university. (I am a native Indian).
Sometimes I think that doing an MBA might give a kick to my stalled career. But these are my fears / constraints.
- I still do not have enough money. My entire life’s saving is around 45K USD. Should I do MBA or not? If yes, should I go for an ed loan (saving my current money for unforseen events) or empty my bank accounts (to avoid paying interest)?
- If I leave my job now, with current slow economy, what will be the ROI of doing a 1 year MBA?
- As per my little research Germany is a country for students (less tuition fee)! If I go for non-US universities (like Germany, Spain, Australia, NZ) I will have to learn their native language to survive there, which needs another 6-8 months.
Please advise if doing a 1 year regular MBA after 13 years of experience worth it? Which universities with good rankings offer affordable MBA?
