What are the best practices to write State-of-the-art Literature Review?
When should we choose to write a State-of-the-art Literature Review instead of a traditional literature review?
Please suggest some literature/articles as well.
Thanks.
Relevant answer
Answer
In addition to the comments above, I seem to have the impression that state-of-the-art reviews - from the ones I have read, seemed to not only provide a broad spectrum of knowledge as suggested by Tushti Sharma - it provides information that is most up-to-date so has to incorporate the latest literature and evidence to provide guidance and advice on the latest methods. This will, of course, incorporate primary sources as mentioned by Jennifer Garcia .

Question

I have quantified the intensity of bands obtained in gels in which I have loaded experimental samples with WT enzyme and several mutants. My goal is to compare whether the WT enzyme or the mutants are better based on the intensity obtained for each band (the higher intensity I measure, the more activity the enzyme has).
I have several replicates of the experiments, I have normalized the values with respect to WT in each case, and then I have calculated the mean and standard error values. So I get a value of 1 for the WT enzyme and values ​​below 1 or above 1 for the mutants. Would this be a correct way to express the results?
I wonder if it would be more appropriate to apply log2 to the values ​​obtained, so that values ​​close to 0 will indicate that the mutants are similar to WT, positive values ​​will indicate that it is better, and negative values ​​that it is worse.
ADVANTAGE:
Applying log2 maybe is useful because the same absolute value is obtained when an enzyme is 10 times worse or 10 times better (compared to the case of not applying log2, that the enzyme 10 times worse will have a value of 0.1 and the 10 times better will have a value of 10)
PROBLEM:
There are cases in which the mutants have a value of 0 because no band to quantify is obtained. So I can't apply log2 to 0 and the graph is incomplete for those mutants. And there are also times when the intensity is very low and when applying log2 a very high value comes out that distorts the graph.
ADDITIONAL PROBLEM: HOW TO NORMALIZE WHEN REFERENCE VALUE IS 0
Under certain conditions I obtain values of 0 or very close to 0 for the WT enzyme, which is the one I use as reference to calculate the ratios. What can I do in this case? Would it be correct to do this: I normalize the data with respect to a mutant that has high values, calculate the mean of the ratios, and normalize the means with respect to WT. In the Excel file “Problem” I have put an example of this under the heading “Situation 1”.
I'm not sure if it's correct to work with the data in this way. In the spreadsheet I have written an example called "Situation 2" in which I have normalized the data in both ways (with respect to WT and with respect to mutant 1) and I see that the final results are completely different.
What do you recommend to do to display the data correctly?
Relevant answer
Answer
I would calculate the ratio, as you did, of the mutant to the wild-type. Mutants with less of whatever you are measuring would have values less than 1 (possibly 0), and mutants with more would have values greater than 1.
If the numbers vary over a wide range, then you can plot them on a logarithmic scale to spread them out so all the data points can be seen. I would use a log10 scale, personally, but I don't see anything wrong with using a log2 scale. Since you can't show zero on a log scale, you could omit that data point and simply state in the figure legend or text that no point is shown for that mutant because its value is zero.

Just to illustrate my opinion here is an example. Look to the OS project VeraCrypt. Its a popular open-source tool for disk encryption available for Windows, Linux and macOS. VeraCrypt is a successor of TrueCrypt, an encryption software whose development stopped in 2014 and which is no longer maintained by its developers. At a certain point the code was reviewed by the German Federal office for Information Security (BSI) - so the German government decided to close the gap of the missing code review.

Question

Hi, I was hoping someone could recommend papers that discuss the impact of using averaged data in random forest analyses or in making regression models with large data sets for ecology.
For example, if I had 4,000 samples each from 40 sites and did a random forest analysis (looking at predictors of SOC, for example) using environmental metadata, how would that compare with doing a random forest of the averaged sample values from the 40 sites (so 40 rows of averaged data vs. 4,000 raw data points)?
I ask this because a lot of the 4,000 samples have missing sample-specific environmental data in the first place, but there are other samples within the same site that do have that data available.
I'm just a little confused on 1.) the appropriateness of interpolating average values based on missingness (best practices/warnings), 2.) the drawbacks of using smaller, averaged sample sizes to deal with missingness vs. using incomplete data sets vs. using significantly smaller sample sizes from only "complete" data, and 3.) the geospatial rules for linking environmental data with samples? (if 50% of plots in a site have soil texture data, and 50% of plots don't, yet they're all within the same site/area, what would be the best route for analysis?) (it could depend on variable, but I have ~50 soil chemical/physical variables?)
Thank you for any advice or paper or tutorial recommendations.

A quest for real-world examples (Best Practices) from developing countries.
Some research findings show that there is a significant relationship observed between entrepreneurship education and entrepreneurial culture. Given the private sector’s involvement is essential in economic development and also that the capacity to recruit new graduates in the formal sector is very much limited, it’s highly vital that existing and new entrepreneurial cultures are adequately exploited. And, it is also necessary to link this cultural dimension with formal entrepreneurial education.
Is there any program/project successfully implemented so that those two issues are properly linked and resulted in achieving the desired goal (As Best Practice)? (Good if country and program/project examples are mentioned.)
Many thanks!

Answer
I appreciate you Mr Melkamu Tadesse Wazza that you have raised the mind blowing question in RG.Entrepreneurship Education is a streamlined program designed by the respective Government to tap up the potential entrepreneurial skills, knowledge and techniques to promote the budding entrepreneurs in the particular location.
The term Entrepreneurial culture means that practices are being followed over the years or decades among the young entrepreneurs in the given geographical location.
Of course, the Entrepreneurial culture is not exploited in some societies due to some factors which hinders the development of those entrepreneurs.
There will be a wide gap between these two groups of entrepreneurs. Some societies may not encourage the entrepreneurial culture because of the lack of awareness, knowledge and skills among the young entrepreneurs.
It is very challenging issue among the budding entrepreneurs those who are reluctant to apply the new skills, knowledge and technical ideas etc to the society.
It is important to note that the psychological factors like Achievement Motivation, Perception, Attitude and Awareness creation etc could help to change the mind of these entrepreneurs in the given society.

For Action Research through the famer field schools (FFS) approach to learning conservation agriculture, initiated by the FAO.
The principle of the Farmers' Field School is to create a place of exchange and learning where producers learn as a group on their own through observation and exchange. The Global Good Practices Initiative aims to make information and know-how on extension easily accessible to a wide audience of practitioners.
KEY PRINCIPLES OF FFS
1. Learning by doing - adults learn best by practical experience than through passive listening during lessons lectures or demonstrations.
2. Each CEP is unique with regard to its content: they are farmers who decide what is relevant to them and what should address CEPs.
3. Learning from error - everyone's experience of reality is unique and valid.
4. Learning to learn - farmers strengthen their capacities to observe, analyze and make informed decisions.
5. Asking problems / finding solutions - the problems are presented as challenges and not as constraints.
6. Field schools are the learning ground - the field - a the agricultural or livestock system is the main learning tool.
7. Agricultural advisers are facilitators, not teachers - because their role is to guide the learning process.
8. There is strength - as a group, farmers have more power than individual producers.
9. All CEPs follow a systematic training process - the key steps are observation, group discussion, analysis, decision making and action planning
In a typical FFS, a group of 20 to 25 farmers meet once a week in a field and under the guidance of a trained facilitator. In sub-groups of five, they observe and compare two plots over the course of an entire agricultural campaign. One plot follows conventional local methods while the other is used to experiment with what might be considered "best practices". They experiment and observe key elements of the agro-ecosystem by measuring plant development, taking samples of insects, weeds and diseased plants, conducting simple cage trials, or comparing the characteristics of different plants, soils. At the end of the weekly meeting, they present their findings in a plenary session, followed by discussion and planning for the weeks ahead. Alternative practices are not assumed to be automatically superior to conventional practices. It's up to the farmers to decide what works best through their trials and observations. FFS is about providing a risk-free environment in which to discuss, dissect, modify and experiment with new ideas for natural resource management in general. Within this framework, farmers are able to study a wide range of subjects, such as integrated management of soil fertility, conservation agriculture, management of hydraulic or water resources, variety selection methods. local and seed quality issues; the risks associated with toxic pesticides and the implementation of low-toxic alternatives; developing marketing skills; and the diversification of agricultural production systems with new crops for food, fodder and profitability. Nationally and regionally, the list of topics continues to expand. The "learning by doing" approach encourages farm-oriented experimentation, group organization and decision-making, increasing the likelihood that farmers will eventually "own" and adopt the improved practices. At the end of the season, a typical FFS group organizes a field day to show local politicians, government agricultural officials and other farmers what they are doing. Exchange visits with other FFS are also encouraged. The season-long approach helps develop stronger social bonds that continue after the initial FFS. Not all topics can be covered in one season, and FFS groups often continue with new topics and activities in subsequent years. Exploring past trends, the current state, and future scenarios allows groups to prioritize needs, interests and actions for the future. National FFS programs are more than just a collection of FFS. They generally operate at different scales to develop social capital, for example by enabling the strengthening of producer organizations and contributing to greater organizational capacity across the entire value chain - from finance, post-harvest processing and production, marketing to investments. National FFS programs are starting to work in concert with other participatory community initiatives, including community listeners' clubs.

Answer
Freezing whole blood samples is not recommended as it causes cell damage. One freeze-thaw cycle could be tolerated, if you thaw the samples at 15-30 degree C. Freeze-thaw cycles generally render blood samples unusable for molecular studies as freeze-thaw can lyse cells and these lysed cells could release nucleases. It would have been better if you would have isolated PBMCs from blood within 6-8 hours after blood withdrawal and frozen the cells instead of freezing whole blood.
PBMCs are isolated by density gradient centrifugation, as different components of blood have different densities and can be separated accordingly. The density gradient medium most used is Ficoll or Ficoll-Paque.
To preserve PBMCs at ultra-low temperatures in liquid nitrogen, PBMCs at 5-10 x 10^6 cells/mL are resuspended in freezing medium containing 10% DMSO + 10%FBS + 80%RPMI medium, and are placed inside a freezing container (i.e. Mr. Frosty) at -80°C overnight to allow gradual and even cooling. The following day, samples can be moved to a liquid nitrogen tank for long-term storage. You could later thaw these cells at 37 degree C for further analysis.

Dear research community,
i am looking for methodological papers (or a scientific approach) or best practice paper that utilize the same methodology. Due to page limitations we are not able to conduct a literature review. However, our intent is to rely on well-known journal only papers in our discipline and analyze them for a specific aspect, thus conducting only a backward search based on these papers to create a body of literature. By doing so, we want to reach a sufficient rigour without conducting and documenting a completely new literature review.
I am not sure if a metastudy is something like what we want to do but a metastudy is rather abour a quantitative analysis of the literature.
If our approach is realistic and applicable i would be happy for every suggestion how to do it. Any methodological paper on such an approach or any best practice paper would help.

Hi. I am struggling with the mouse animal model. I found that the subcutaneous tumors are extremely uneven in my mode. I injected the same volume of tumor cells (human cell line) suspension s.c. in balb/c null mouse and the size of the tumor show uneven after 1-2weeks. This has a great impact on the following treatment. So, I wonder what is the best practice for subcutaneous tumor inoculation? Or, are there any ways to prevent uneven tumor growth?
Thanks a lot!
Relevant answer
Answer
1) I hope that by "the same volume" you also understand the same number of tumor cells.
2) Try to prepare suspension of cells just for a few mice (depending on your expertise) to minimize the time of cells waiting on the bench in PBS before being injected. Then prepare a second vial of cells for another couple of mice and so on.
3) Be careful not to go too deep with a needle- in case like this tumor may infiltrate the muscle and from the outside, by eye, it may look like the tumor is smaller than it actually is.
4) If for some reason the size of the tumor is essential for your therapy then don't focus on starting the treatment on the same day- just set a volume of the tumor on day 1 of the treatment and start the therapy when each of the tumors will reach a given volume.

Hello,
The simple method to check for bacterial contamination is by checking for turbidity both in the RPMI medium as well as in the culture flask.
If you suspect contamination and turbidity is not visible, you can streak a few micro litre of RPMI medium or the medium from the flask on to the LB agar plate, and incubate the plate in the incubator at 37 degree C overnight. If there is bacterial contamination you will find bacterial colonies on the plate the next day.

I am new to this I am currently doing my dissertation and has some cases where there is data missing. What is the best practice? Should I remove these cases, replace the missing ones with a mean value, any advice would be helpful. I have 527 cases but will be left with 318 if I delete the cases with missing values
Relevant answer
Answer
Missingness is interestingness. Rather than just regarding missingness as a nuisance – which it is – you also need to ask yourself why a lot of data are missing. For example, no data on smoking in a patient's chart leads to the question of what kind of doctors don't ask about or record smoking, and what kind of patient is ignored. Missing data on sexual side effects of medications can reveal a lot about our biases – it tends to be missing in older patients, patients with mental health problems and with learning disability.
Missing data on ratings scales can uncover blocks of question that simply don't apply to a significant number of people, like questions that assume that they are employed. Or, in the hilarious case of a scale meant to evaluate the burden of hernias on the person's daily life, there was an item about finding it difficult to climb stairs. You can imagine how that item fared in Malawi!
So before you write off the missing data, try and find out why it's missing. There may be a story in that.

For my experiment, we are examing the effects of estrous stage on heroin withdrawal enhanced fear learning in rats, and for several of the test days we would like to acquire the vaginal cells by washing with saline from a pipette. However, we wanted to perform this procedure several days in a row, and I was worried about the possible stress of repeatedly doing this to the animal. Is it okay to perform the flushing technique repeatedly? I can't find anything on the best practices for this or any info about the possible stress it induces. Thank you!

Hi, Lydia!
Vaginal lavage is a stressful manipulation, so you really have to be careful about it. Few papers show higher corticosterone levels and higher cardiac frequency after the procedure.
There's also a paper showing that it attenuates cocaine-stimulated activity, establishes place preference in rats, and masks the existing difference between estrous cycle phases.

I have an atomic force microscope (AFM) with scanning capacitance mode (SCM). I would like to find a known good sample that lets me check if my tip and microscope are working correctly. For topography we have gratings. For magnetic force microscopy, we have magnetic tape. What is the equivalent for SCM?
Beyond a quick check, are there specimen or best practices for calibrating the capacitance measurements?
Relevant answer
Answer
SCM) is a contact mode variant of atomic force microscopy (AFM) in which changes in tip–sample capacitance are imaged simultaneously with surface topography. Samples for SCM analysis are generally covered with a thin insulating layer that serves as the capacitance dielectric between the tip and sample. The spatially mapped capacitance variations can be attributed to changes in the dielectric thickness, changes in the dielectric constant, or variation in the local charge carrier density underneath the dielectric. In the most typical application of SCM, which is the characterization of semiconductor devices, capacitance variations are converted via a theoretical model into a dopant concentration profile in the semiconductor underneath the dielectric.

I feel like maybe this question is so easy that it's hard and I keep doubting every choice I make, so I thought I would just finally ask online. I have one dependent variable with three levels: percentage of caches a bird make in one of three different types of substrates (sand, gravel, or other). My independent variable has two levels (the three conditions the birds are in whilst caching).
I pretty much know my pattern of results and I have figures drawn up and everything (I can post a small subset of the data if that would be helpful to people in answering the question), but I cannot, for the life of me, figure out if I have chosen the right test to analyse this data and I keep having doubts every time I make any progress.
I'd ran a similar study not too long ago that was almost identical, except the independent variable only had two levels (gravel and sand). Therefore, I could just run a Friedman ANOVA (since the data violated normality assumptions) for percentage of caches in one or the other substrate.
Right now the only solution I have been able to come up with for this is running multiple Friedman ANOVAs, but, as mentioned, I am really starting to doubt this. This is primarily because--unlike when I only had 2 levels in my DV--, I cannot just run a test for one of the levels (e.g. in my first experiment, if 25% of the caches were in sand, you automatically knew the other 75% were in gravel; however, for this experiment, if 25% are in sand, that only means that 75% are in gravel or "other" and you do not know how it is divided up between the these two).
I know there are more advanced forms of analysis as well, like mixed models, but I've been specifically advised against doing those in this particular instance.
It's just that I keep writing and writing, then I get freaked out about my stats, so I do a bunch of research, then I try to re-calculate and re-write….and it's getting to the point where I can't do that anymore. So, I kind of need to know now if I need to change my method of analysis.
Could anyone give me advice?

Hi all,
I've always wanted to try harvesting and analysing data from NCBI, but I've just never really known the best way forward. I know that I can easily download a whole bunch of data from NCBI by just searching for a group on the website, Geneious, or any other number of programs/scripts. But, I end up with a big mess of data that seems difficult to sort through and actually use.
So, for those who routinely download NCBI sequences — particularly using R — can you point me in the right direction of packages or tutorials to make it easier to:
  • Summarise the available data (say by species within a particular genus) on the online databases. Perhaps with an output table showing the number of sequences available for genes X, Y, and Z by taxon A, B, and C.
  • Choose the genes (i.e., several commonly used phylogenetics genes) and the species you want and download them into an alignment.
  • Follow up question — It doesn't look like these databases store a specimen identifiers. So, do I need to trawl through each paper's tables to then link different genes from a single specimen together. Or, do people usually just link genes together from the same species to get a full compliment (this seems dodgy and prone to author error in identification).
Perhaps there is already a document or paper that really summarises these issues and the best-practice nicely, but my search queries haven't found it yet.
Many thanks in advance!

Question

I am currently conducting latent profile analyses in Mplus, but I have a hard time finding any recommendation for how to choose variance/covariance matrix. In my experience, less constrained models (with class-varying variances and covariances between items within classes) results in better fit statistics, but it is more difficult to find the "best" model (i.e., replicate the best loglikelihood values) and computing times increase substantially.
My current approach is to run a number of different specifications for variance/covariances and determine the best number of classes for each specification. Then I compare solutions for different specifications to see which solution that provides most relevant information about my study sample. But is there a more systematic approach to choosing variance/covariance matrix? Are choices based on a priori assumptions recommended? Are there any publications describing how to choose specification, e.g., for different types of data? Any help would be much appreciated.
Relevant answer
Answer
Christian Geiser and Mark Shevlin, thank you both for the references. I really appreciated the "non-technical" approach of the Johnson paper. It seems like the procedure I use is more or less the same as that of others, and there is no easy way of determining the best specification (although a less constrained model is better at reproducing the true class number, with the downside of resulting in more inadmissable solutions and longer computation times).
Mark Shevlin, yes that is correct, the default model for LPA in Mplus constrains the variance to be equal across classes, though they are allowed to vary within classes, and covariances are constrained to 0. This is the most constrained model I have used. I noticed that the references you provided mainly concern modelling with repeated measures, but I assume that certain conclusions would apply to the simpler LPA-model too. E.g., that the more restrained models have a tendency to over-extract classes, and that the least constrained model that converges without problem most likely represents the data best.

How do we Justify the " who, when, and where" conditional in the theoretical model?
Relevant answer
Answer
There are several considerations in the process of addressing this question (Finding the Right Theory). For example, the area of knowledge we are dealing with is very important. In Physics, a researcher has a hunch and immediately tries to define a mathematical model to back it up, then later experiments will follow to link abstractions to reality. The original theory was a hunch or a hypothesis justified by limited prior knowledge and logic.
In applied areas such as business and IT management, the research question needs to be important in practice. Whichever accepted research models have been validated provide a strong guideline. If validated measures for the relevant constructs already exist, so much the easier. On the other hand, often new technologies or new ways for business innovation gets ahead of existing theories; new theories must be proposed, new measures must be developed.
I hope that helps.

I have had a few lively discussions with colleagues on the appropriate application of the following terms, as they relate to the use of laboratory rats and mice: habituation, acclimation, adaptation, and acclimatization.
When the rats are brought into my research lab, in order to "get used to" everything from the transport from the animal care facility, sounds, sights, odors, etc., is this called habituation?
Preclinical researchers are "on notice" to improve the reproducibility and validity of our data, with the ultimate goal of translatability to clinical discoveries. How can this be accomplished if we cannot even agree on terminology?
Relevant answer
Answer
To me, when thinking about those words and their common uses, I have them divided up in my head a certain way. Your mileage may vary, but here's how I use them.
Acclimation and acclimatization are the same thing-- getting used to life at a different place than the animal producer. I like acclimation better as acclimatization just seems....extra.
Habituation is getting used to something happening--animals are habituated to restraint, they are habituated to a behavioral testing apparatus.
And finally, adaptation is a longer-term event occurring at the species level to permanent changes--the rats are adapted to living at altitude; the mice have adapted to desert life.

Hi Carole,
As a DLI alumna myself, circumlocution was key for effective communication for me both in the training environment and in later years when using my secondary languages. However, it wasn't a skill that was necessarily taught in lessons, per se. Rather, if we got stuck, the teacher would ask us if we could say it a different way. Circumlocution is a useful skill no matter the language or the speaker's level of proficiency. I have even used it with my own children in the process of learning their native language; sometimes they don't know how to say something so we talk around it until they feel the subject has been expressed and understood. It is also a useful skill for military (or others) who may need to broach sensitive topics, particularly in cultures other than their own, where a direct approach may be offensive or ineffective.
Best of luck!

A relict species population is a population that currently occurs in a restricted area, but whose original range was far wider during a previous geologic epoch. Threatened plant species with small geographic range and small population size are most at risk of extinction and the highest priority in urgent conservation programs. As for the relict endemic species, which witnessed during the past 50 years a significant decrease in the geographical area and population size, it is one of the most important primary goals of conservation, whether in situ or ex situ. In some cases, ex situ conservation is the only available solution to protect a species from extinction and to ensure the possibility of an attempt to return to the wild after its extinction after the improvement of the surrounding environmental conditions. Unfortunately, some species depend on the range of environmental variables so small that by changing the organism cannot adapt to and it becomes extinct. For example, in the cases of plants that depend on the availability of a constant and continuous water source throughout the year, they are subject to a significant collapse in the absence of that water, especially in desert environments. The question now is, how can we increase the chances of conserving these species through in situ practices, given the weak opportunities for long-term financing?
Relevant answer
Answer
Natural products are capable to adjust with adverse conditions. Yes, the capability of them varies with their species. When we can save the seeds with our technology, we can recreate the condition of their growth. In my point of view, extinction, of course the natural one, is very normal. That is the way of generation of aa new species. But extinction that is done by human greed is the problem creator.

We're using a fluorometer (Horiba Aqualog) to analyze fluorescent dissolved organic matter (FDOM) in water samples. The samples are analyzed in quartz cuvettes, which must be bathed in a solution of 50% nitric acid for 24hrs. In theory, the nitric acid bath can be reused between multiple runs.
I'm now trying to find a lidded container that can safely hold 50% H2NO3 at 20 degrees C inside a fumehood for a week or more without damage. Minimum internal dimensions would be approximately 15cm square bottom and 3cm deep. We've considered jars or large beakers, but we need something wide enough to fit a butyl-gloved hand into to handle the delicate cuvettes.
In terms of materials, plastic options exist (https://www.calpaclab.com/chemical-compatibility-bottles-containers/). Teflon would be the "gold star" but I've found no teflon tanks available from suppliers. I'm currently looking at a Nalgene LLDPE rectangular tank with lid. Another idea is a glass bakeware dish with lid (much cheaper and AFAIK 50% nitric won't attack glass).
But I'm curious to know what others are using.

Dear all colleagues,
I run small research about binary classification with Decision Tree. I have about 9000 data consist of about 68 features. I use sklearn for my library for this research since I use Python as programming language.
I use proportion for train and test with this sequence: 7:3,5:5 and 1:9. However, i found that each proportion has high accuracy for the test result (greater 90%) which lead me to suspicious about over-fitting. What is the best practice to investigate the indication of over-fitting of my model?

Hi all,
I've conducted an exploratory factor analysis with 365 participants, and all the data largely is reliable and has gone according to plan. However, when looking at the rotated component matrix (varimax rotation conducted), one of my questions doesn't load onto ANY factor whatsoever (no number is displayed). I've tried to find answers to this, but can't seem to find any papers that illustrate what to do when this happens. I would assume that in this case, I would discount the question altogether?
Can anyone advise on best practice, or guide me towards a paper that may answer my question?
Thanks!

Answer
Rachel Cholerton, You are being provided with some advice up above that is well worth considering. I would make two other suggestions.
One is to use an oblique rotation (e.g., promax) rather than an orthogonal rotation (varimax in your case) because most items in an EFA are related to each other.
The other is to look very closely at any item that does not load on any factor. As has been indicated above, that item could refer to something important that does not relate strongly to other aspects of the overall construct you're measuring. If it is important, one strategy is to now create more items that you believe would be related to the "odd" item, and then obtain another set of data in which those items are included to see whether they do represent an important factor in a new EFA.
I would also look carefully at the wording of the odd item to see whether something about the way it was presented resulted in "unusual" responses. If that turned out to be the case, maybe a simple change in wording in any future research would be advantageous.
If the item turns out to be faulty or just on a different (and probably unimportant) planet, and you're not in a position to collect more data, it's probably best to simply delete it and re-run your EFA.
Incidentally, I hope you are not using the Kaiser criterion (eigenvalues greater than 1) to determine the number of factors in your data because that method often suggests there are more factors than there really are. Instead, it is better to use the scree plot or, even better, parallel analysis. In the past, parallel analysis was avoided, but software is now readily available for conducting it and it's really easy.
You'd asked for some useful references. Peter Samuels' study guide (that he recommends in his post above) is useful. I think the following might also be authoritative and informative:

Dear all
What can be defined as a threshold for engine operation in-cylinder deactivation or skip fire mode?
Keeping below 5% COV of IMEP is no longer feasible right? So what can be the best practice?
Relevant answer
Answer
After years of operating experience, most manufacturers have abandoned skip firing. While it does hold for some promise, it comes with so many problems that other paths lead more directly to improvements. In short, skip fire sounds good, but doesn't work out well. A similar situation killed the Wankel engine. It too was fascinating, but impractical. Any development you can come up with to improve it (advanced rings, seals, and surface treatments) could also be applied to a reciprocating engine so that the Wankel could never pull out ahead as a better way. Much larger heat transfer area (think losses and huge radiator) and swept area (think lubrication and sluffing off residual every rotation resulting in higher emissions and huge catalytic converters) can't be fixed and buried the Wankel engine. Skip fire is a similar path to nowhere.

I am looking to perform a co-IP; however, I am using a very small amount of tissue to begin with from region specific microdissection in mice (2-3 300um sections per animal). I am concerned that there will not be a sufficient amount of protein and/or the sample will be dilute. Are there any best practices for performing these types of experiments when the yield is low? I know one way would be to collate samples across animals, but this is something I am trying to avoid.
Thanks in advance!
