A recurring theme in metaheuristics research is to consider the balance between Exploration and Exploitation. An often forgotten area of research is the effect of Selection on Search/Exploration. A method of selection that rejects all exploratory search solutions can cause any metaheuristic to stall, and elitist fitness-based selection in continuous domains often behaves in this fashion. A building body of research suggests that alternate methods of selection are required, and that these methods of selection should be specifically matched to the employed methods of exploration.
We invite all interested researchers to join our workshop to expand upon related research topics such as
  • Benchmark problems for exploration
  • Methods for exploration (and their verification)
  • Observation of optima hopping behaviours in metaheuristics
  • Comparison of selection in combinatorial and continuous domains
  • Measurements of stall and/or selection errors
  • Non-fitness based methods of selection (for exploration)
  • A review of selection
Workshop participation is open to all conference attendees. If you would like to present relevant research during a plenary session of the workshop, please contact the organizers:

We invite discussions, suggestions, and collaborations on the following: Mathematics is the mother of all the sciences, engineering and technology, and a normed division algebra of all dimensions is the holy grail of mathematics. Singh along with Prof. SD Joshi (IIT Delhi) and Prof. Anubha Gupta (IIIT Delhi) developed normed division algebra of all dimensions which is available in preprint at: https://doi.org/10.13140/RG.2.2.18553.65120/3
A summary of "On the hypercomplex numbers and normed division algebra of all dimensions: A unified multiplication":
Key Points:
  • Expanding Number Systems: The paper proposes a way to create hypercomplex numbers (numbers with more than two dimensions) that extend the traditional complex numbers.
  • Overcoming Dimension Limitations: It challenges the previous belief that only four real division algebras exist (with dimensions 1, 2, 4, and 8).
  • Unified Multiplication: It introduces a new multiplication method, called "scaling and rotative multiplication," that enables the formation of normed division algebras in any finite dimension.
  • Key Properties:These hypercomplex number systems are non-distributive, meaning that the usual distributive property of multiplication over addition doesn't hold. They are compatible with existing multiplication for dimensions 1 and 2, meaning they smoothly extend complex numbers.
Potential Implications:
  • Broader Mathematical Applications: This work could lead to new developments in various mathematical fields, such as abstract algebra, geometry, and analysis.
  • New Frontiers in Physics and Engineering: Hypercomplex numbers have a history of applications in physics and engineering, so this expansion could open up new possibilities in those areas.
Next Steps:
  • Further Exploration: Further research is needed to explore the properties and potential applications of these generalized hypercomplex numbers and their associated algebras.
  • Rigorous Evaluation: The mathematical community will need to carefully evaluate the proposed multiplication method and its implications.
  • Interdisciplinary Collaboration: Collaborations between mathematicians, physicists, and engineers could help uncover new applications for these generalized number systems.

Consider the issue that one phase of your work may raise questions or lead you to identifying the need for more information. From a reflexive perspective from anthropology, this leads to the need to re-enter the archive. If you want to see a logic for this, you can explore several chapters in our 2023 book (ebook) that makes these processes in educational contexts transparent to readers. The book is Interactional Ethnography: Designing and Conducting Discourse-Based Ethnographic Research. The concept of reflexive analysis is also visible in the work on Michael Agar (see his website) in Language Shock, the Professional Stranger and Culture can you take it anywhere (FQS) for a rationale from an anthropological perspective.

A very interesting question. Before I give my thoughts, just a small remark. If we were to discover alien life, it would most likely be within our own galaxy, the Milky Way Galaxy, which has a diameter of about 100.000 light years. So the intelligent life we find would just be thousands of light years away, not millions.
At our current level of technology, it would be impossible to interact with the aliens in any meaningful way because of the vast distances in interstellar space. So the important question is how humans would change their behavior towards each other given that new discovery. I find it difficult to guess how humanity would react here. Humans have written plenty of sci-fi about this topic though.

With the James Webb Telescope, will we learn the answer to age-old questions about the existence of extraterrestrial life forms, other life forms, intelligent other living beings, other civilisations operating on exoplanets billions of light years away, located in other planetary systems, in other constellations, other stellar constellations, located in other galaxies, galactic nebulae, etc.?
For centuries, man has been searching for an answer to the question of whether life originated and developed only on planet Earth, or whether it originated beyond Earth and came to Earth, e.g. whether life originated and developed only on planet Earth, whether it originated beyond Earth and came to Earth, e.g. in the form of simple microorganisms in the rocks of meteorites falling to Earth, whether it also developed in many other places in the Universe, whether life also developed, used to function and/or still functions, whether other forms of life developed, whether other intelligent life forms developed, whether these other intelligent life forms have created other civilisations on other exoplanets many millions of light years distant, located in other planetary systems, in other constellations, other star constellations, located in other galaxies, galactic nebulae, etc.? ? For several decades now, as man has been building ever more perfect space telescopes and listening for sounds from distant corners of the Universe, the possibilities of answering these questions have been gradually increasing. On the one hand, cosmologists, astronomers, researchers into astrophysics, the biosphere of the cosmos, etc., are trying to estimate the number of exoplanets which are at a similar distance from their suns as the planet Earth, have a sufficiently abundant amount of various elements and chemical compounds, and have the potential for the emergence of at least simple forms of life. On the other hand, it has still not been possible to hear a sound from space that would be evidence of the existence of another civilisation. It has still not been possible to photograph exoplanets millions of light years away in such a way, with sufficiently close-ups in the photographs, that traces of other life forms can be seen. But technological advances in the possibilities of space exploration and research are continuing relentlessly. Recently, the most advanced space telescope to date, called the James Webb telescope, was placed in Earth's orbit. The James Webb Telescope is currently the most perfect device ever created by man to photograph distant cosmic objects, distant galaxies, constellations, planetary systems and also exoplanets, millions and billions of light years away. This telescope is superior to the previously used Hubble Telescope for infrared observations. The James Webb Space Telescope was built between 2007 and 2021 a space telescope for observing and taking pictures of distant space objects mainly in the infrared. In a sense (observing the Cosmos only in the infrared range), the James Webb Space Telescope is intended to be the successor to the Hubble Space Telescope. Overseen and largely funded by NASA, the project was developed in collaboration with ESA and the CSA. With the James Webb Telescope, it is possible to photograph and study exoplanets located in other planetary systems, in other constellations and to photograph distant galaxies up to 13 billion light years away from Earth. As a result, the James Webb Telescope is already being described as a kind of cosmic time machine, as it takes pictures of galaxies billions of light years away, the photographed image of which shows these galaxies as they looked those billions of years ago. The James Webb Space Telescope was placed into Earth's orbit at the end of 2021, and to date has photographed many cosmic objects that were previously virtually invisible to humans in any way. The date for the launch of this telescope has been postponed several times since 2007, because due to the global financial crisis of 2008 and other economic issues, there was not enough money to complete the project in the previous years before 2021. The cost of building the James Webb Space Telescope was estimated to be around USD 10 billion. In view of the above, the James Webb Space Telescope is the most powerful telescope ever built by man to be placed in Earth's orbit and the most perfect device for taking photographs of space objects billions of light years away. Perhaps, thanks to the James Webb telescope, man will finally get an answer to the above questions.
In view of the above, I address the following question to the esteemed community of scientists and researchers:
With the James Webb Telescope, will we learn the answer to the age-old questions regarding the existence of extraterrestrial life forms, other life forms, intelligent other living beings, other civilizations operating on exoplanets billions of light years away, located in other planetary systems, in other constellations, other stellar constellations, located in other galaxies, galactic nebulae, etc.?

Answer
Dariusz Prokopowicz I think that is unlikely that the JWST will actually detect evidence of life on other planets. I do think that the JWST observations together with rational scientific analysis will show that the Big Bang story of the evolution of the universe must be discarded.
If you think about the hypothetical cloud of gas and dust condensing into stars and then galaxies it just doesn’t match what we observe in the JWST observations of well formed galaxies with a look back time in excess of 13 billion years.
Freed from the constraints of the Big Bang theory we can develop a much better understanding of the formation of the solar system which will in turn give a fresh appreciation of how unique and unlikely is the planet Earth.

Or, by what formal means can we comprehend and communicate the nature of Nature?
From Mathematics: Nature and physics are “independent of mathematics”
From Physics: “We need the criteria of something that actually works, not just math rigor.”
“I appear to be caught between two successful disciplines, mathematics and science - rigor and usable results.”
[For full versions of the quotes in justice to the individuals review “What Is a Linear Representation of an Essentially Quadratic Phenomenon?” in Q&A on ResearchGate. Applied Mathematics is not specifically mentioned in the posts there.]
There exist phenomena in nature, for example kinetic energy of a mass in motion, which may be represented by the product of the mass times its present velocity times the linear average of its velocity between zero and its present value (K.E. = m*v*v/2 to clarify.) Now, ignoring the abstractions of mathematics and the accurate-enough theories of physics, what are the axes of any space in which kinetic energy may be plotted, noting that in that space energy is represented by a volume, area times length, and the area may be linearized with v as the square root of the area? Note that two axes of v and v/2 are needed to plot the area. What’s up? What are area and length in nature that are plotted in such a space? Is it significant in the natural process that v*v is an area in the plot? Is energy an essentially quadratic phenomenon of nature, or even essentially cubic? Are these matters so answered already they may be dismissed, or may some of us explore them for the insight that may bloom (flowers “blow” in some poems)?
These are questions of Natural Philosophy in the mind of a person that are not answered by the rigid explanations of the current state of ignorance that feels so knowing in each era. Aristotle’s view was great in his time, like ours is to us now. (The accepted solution is for an academic to fix the person who errs with an inoculation of facts “it is known that,” a familiar experience. In Charles Ives musical work, “The Unanswered Question,” the trumpet remained curious after the explanations.)
Looking to the 4thmillennium in the Gregorian calendar, will this inquiry have been resolved as natural processes are then comprehended? Given scales and data a number may be assigned to a measured kinetic energy that is accompanied by units to associate it with nature. The issue seems moot, but in fact, . . .
The Schrodinger Eqn. is a linear representation used in calculation that must be squared to be real, that is, the real result is a squared value, calling it quadratic will serve. The square root of two is formal, but the Schrodinger Equation produces a real value in the end after multiplication by its complex conjugate, “squaring.” The physicist is correct that in Physics it doesn’t matter “what the imaginary solution was” during calculation since only the result matters and other representations exist. Is that okay with you? I wonder, since another formal linear representation of an essentially quadratic phenomenon, the square root of two, cannot be written down as a completed decimal value, and during processing the imaginary Schrodinger expression requires representation as an area via a + bi, or (a, b), or . . ., which expressions are not real.
[Remember – ResearchGate encourages discovery, as if current knowledge could not only be incremented, but also that a new arena for thought could be discovered. “It is known that” must not be the whole answer, and exploration is in the charter.]
So, by what formal means can we comprehend and communicate the nature of Nature?

Howdy Robert A. Phillips,
We share a sense of Nature and of knowledge. Your preprint of "The Cause of the Gravitational Effect" reminds me of Albert Einstein's first cut in 1911 at the bending of the path of light in a gravitational field gradient. Your observation on KE in a fluid is appropriate to my fluid dynamics focus, but I would word it "Kinetic energy involves more than just the body. In any case our agreement is quite pleasant.
"Using a natural fluid model to interpret the nature of cosmological interactions resolves many of the "big questions." " You might enjoy my condensation cosmology concept. The Universe did not "inflate," but as primal energy condensed to matter, light slowed (same speed always is measured) and the Universe has appeared to expand.
The issue of whether natural processes "are quadratic" represented by v2 in K.E. = mv2/2 remains of interest to me in forming an object oriented model of flow in a mountain stream rapids. What is happening "in" a turbulent flow structure that must be specified in its object class data and functions, whether it is processed analytically or by a computer program. Imaginary and irrational number expressions may freely be used during calculation as long as they are made rational in the end. Do we need to notice that; does nature notice that; does it matter? Daniel Boone was never "lost" in the Kentucky wilderness, but on occasion he was "mighty bewildered" for days. Maybe I'm just bewildered.
Happy Trails, Len

Dear All,
Recently, I have looked into the Web in search for some works on Search And Rescue or guarding strategies. I have found some works related to UAV exploration in urban environment or SAR disaster site exploration. But, it was not what I really meant.
I wonder if there is any up-to-date literature (analytical, mathematical, physical, simulations maybe?) devoted to search and rescue or guarding, e.g., on the sea. I recall the stories from the time of WWII when allied vessels, after loosing contact with the submarine, started to move in circles with increasing radius. Also, there were special books prepared by mathematicians describing sequences of random turns to avoid being hit by a torpedo.
Do you know if there were any advances in the topic since then? Where the strategies using by modern SAR service are taken from?
Regards,
Michal
Relevant answer
Answer
Hi Michał,
In general, the entire SAR action conducted at sea and especially a selection of the search pattern depends (obviously) on a specific situation. Many factors are affecting the course of the action, such as search area (proximity of the shoreline and nearest rescue center), distance to the commence search point, number of the vessels involved, availability of support for the air (helicopters, aircraft), environmental conditions (usually unfavorable), etc.
When looking from the merchant ship's viewpoint, we have an official manual prepared jointly by IMO and ICAO, the so-called IAMSAR Manual (International Aeronautical and Maritime Search and Rescue Manual) where some procedures to be followed are presented. Among these, there are also search patterns introduced. Their application differs mainly depending on the aforementioned factors (especially the number of the searching vessels or possible cooperation with an aircraft). One of the most common patterns for a single ship is "expanded square", which is very similar to the example of allies vessels action recalled in your question. Other popular patterns used are, among others, sector search (also called a "flower-pattern") - usually with the support of a helicopter, as well as various modifications of parallel track searches - usually in cooperation with aircraft or other ships involved in the SAR action. For more practical information please refer to:
IAMSAR, 2007. International Aeronautical and Maritime Rescue Manual. Volume II, Mission Coordination. IMO/ICAO publications, London/Montreal; or any newer IAMSAR version.
However, in the mentioned IAMSAR Manual, you will find mainly simply operational procedures for the crewmembers of the merchant ships. If you are looking for algorithms or mathematic explanations of the most effective search methods/patterns you have to check scientific sources. There are a few, quite recently published papers about modern solutions in this field. You can see, for instance, the following papers:
Ai, B., Jia, M., Xu, H., Xu, J., Wen, Z., Li, B., & Zhang, D. (2021). Coverage path planning for maritime search and rescue using reinforcement learning. Ocean Engineering, 241, 110098. https://doi.org/10.1016/j.oceaneng.2021.110098
Ai, B., Li, B., Gao, S., Xu, J., & Shang, H. (2019). An Intelligent Decision Algorithm for the Generation of Maritime Search and Rescue Emergency Response Plans. IEEE Access, 7, 155835–155850. https://doi.org/10.1109/ACCESS.2019.2949366

Especially the first publication seems to be suitable for you. When you check the reference list, you can find there the older papers/books from the math domain, like:

From the announcements of politicians, it appears that in a few years manned expeditions to the Moon will resume. On the Earth's moon, bases will be established for the preparation of a man's expedition to Mars, which may already be carried out in a dozen or so years. Manned expeditions to Mars in the perspective of a dozen or so years have already announced the US and China.
So there is a rivalry in the field of who will first make a manned trip to Mars. Will it be a similar competition as in the 1970s between the US and the USSR in the area of ​​the then competing programs of the planned and implemented manned expedition to the Moon.
Or maybe a manned expedition to Mars will not be a competition between the biggest economic and technological powers of the world?

Various metaheuristic optimization algorithms with different inspiration sources have been proposed in recent past decades. Unlike mathematical methods, metaheuristics do not require any gradient information and are not dependent on the starting point. Furthermore, they are suitable for complex, nonlinear, and non-convex search spaces, especially when near-global optimum solutions are sought after using limited computational effort. However, some of these metaheuristics are trapped in a local optimum and are not able to escape out, for example. For this purpose, numerous researchers focus on adding efficient mechanisms for enhancing the performance of the standard version of the metaheuristics. Some of them are addressed in the following references:

Large amounts of research focus on the balance between Exploration and Exploitation. However, this omits the power of Selection which can turn any metaheuristic into a hill climber by rejecting all exploratory search solutions.
To engage the broader research community in this important discussion, we are organizing a Workshop on Selection to be held at CEC2021 in Krakow, Poland. Please consider participating in our event or on our project page.
Relevant answer
Answer
I think you need to be leery against the use of "selection" in metaheuristics as an independent attribute from exploitation. If anything, the two really augment one another. History has shown that metahueristics which have a selection property to it invariably have weak explorative capabilities. Prime well-known examples are Artificial Bee Colony algorithm and GAs.
My guess is that the same metrics that we currently use for estimating algorithmic performance (optimized solution, standard deviation, number of functional analysis, diversity index, etc.) can be modified to examine the so-called "selection - exploration" balance for algorithms, since as I said earlier, selection and exploitation are really just two faces of the same coin.

AI Safety Issues can be categorized into five main classes including "Safe Exploration", "Scalable oversight", Avoiding “reward hacking” and “wire heading”, "Avoiding negative side effects" and "Robustness to distributional shift" (Amodei et al. (2016). Concrete Problems in AI Safety).
Can we categorize safety assurance of Evolutionary Optimisation Algorithms (e.g. Genetic Algorithm) as Safe Exploration?
Is there any approach for quantitative safety evaluation of such algorithms?
Thanks for your time and consideration.
Relevant answer
Answer
I'd say these are classes to categorize the safety issues, not algorithms or families of algorithms.
For safety assurance, you'd need to address all issues relevant to your application.
Although safe exploration might be most important for Evolutionary Optimisation Algorithms, you'd still want to also avoid negative side effects.

I explored different packages (such as mgcv, MCMCglmm, glmmADMB, etc) but they all have limitations. Either they don't allow for zero-inflated, zero-altered distributions or they don't allow for temporal auto-correlation through functions as corAR() or corARMA(). 
Relevant answer
Answer
A late addition to this question as there have been developments since then. mgcv can now handle this model!
1) The supported family of distributions has been expanded and zero-inflated Poisson can now be specified. [see ?family.mgcv ]
2) Smoothers can now be used to model the autocorrelation using a Gaussian Process [ + s(timevar, bs = "gp") ]. There is an example here:
(3) Random effects can be modelled using smooths as before. A recent paper goes over it in detail:
So the mgcv model would look roughly like:
gam(counts ~ ... + s(time, bs = "gp") + s(groups, bs = "re"), family = "ziP", data = mydataframe)
Hope that helps someone!

I am working on autonomous visual navigation using deep reinforcement learning (DRL) for UGVs. I used valued based algorithm (Dueling-DDQN) to trained my robot in the simulation. I also applied parametric noise for better exploration. I got good results and submitted it in a good journal but got rejection. One of the reviewers asked me this question. "Why deep Q-learning + parametric noise? Is there any reason why A3C or other alternatives would not work in autonomous navigation? Why is entropy not a valid choice for exploration?"
A3C comes under policy-based algorithms which is not my area or hasn't discussed in the paper. We can achieve autonomous navigation using this method, i know, but why he raised this question? I googled about entropy for exploration and found many papers but all of them used the policy-based method with it. no one used it with a value-based method. How i can compare it with parametric noise? How i can answer this question, "Why is entropy not a valid choice for exploration?"
Anyone in this field, please answer my question. I read many articles but not found the answer.

Answer
Hi Mudassir
I guess it is a problem of methodology here and how you stated the problem you wanted to address.
If the problem you addressed is "ugv navigation" and you came up with "deep Q-learning + parametric noise" and you said I have good results, the question is then "good results with respect to what ?" you need to compare your results with other existing solutions - usually taken as references in the field - and explained why you outperformed them. Otherwise reviewers will consider that you developed another algorithm but you did not bring additional "values/insight/knowledge" to the field - specially when you want to publish in a journal.

Dear Zehra,
Only one criteria; the Aim, Goal, or Objective.
Without a clearly defined objective it is virtually impossible to measure success of any program. That is why you got such different answers - all of them true and valid, but not really answering your question. Each answer addresses a different measure of success, because each evaluates a different objective.

I want to know if there are recent approaches for hydrocarbon exploration using gravity data. Also, is there any recent modifications on the gravity stripping technique in hydrocarbon exploration?
Relevant answer
Answer
Dear Ahmed,
I believe that a strong statement cannot be made regarding the limitations of gravimetry or magnetism without having evidence or data to endorse and verify them.
It happens many times that the comparison is not valid, because it is clear that seismic is a quintessential tool in reservoir characterization, especially in the case of loans in the domain of prestack elastic inversion, both, for fluid / lithology discrimination.
Such as Naeim said above, the integration of methods is the clue to solve the subsurface geometry.
But both, gravity and magnetic, are not only for Exploration stage (e.g., new frontier areas), but also it is very useful in Development or Reservoir Management: thinking about the case for instance of the 4-D Gravity Survey to characterize fluid contact in boreholes.
Even without this 4-D, gravity and magnetic aerial surveys are critical for example in areas with environmental restrictions, or logistical limitations in the stage of Reservoir Management. Thinking about the use of gravity and seismic for depth pre-salt imaging of complex hydrocarbon systems (Recóncavo Brazil / Gabon-Congo system; Santos-Campos Brazil / Kwanza – Benguela Angola).
Another example of the use of gravity anomalies in Reservoir Characterization is related with the construction of the low-frequency model to run seismic inversion. Remember that for potential method environment softwares, you can export a SEGY file with your gravity inversion, load in the seismic interpretation environment and go on with your low-frequency model previously to run the acoustic-elastic- seismic inversion workflow.
Let me show you two examples of my own experience that I compare the 3D seismic basement imaging with magnetic solutions and be careful of the sizes and the statistics that I show you, you take a better idea about the advantages.
I hope this answer will be useful for colleagues and you.

I'm struggling to understand the significance of the fat-tailed distribution especially in career choice. 80000hours career guide argues that the more accurate distribution for career choice is the long-tailed one.
I'm trying to understand how the implication would differ between a normal bell-curve and a long-tailed distribution. My request: are the implications I wrote in "Part 2: Significance of the fat-tail distribution" accurate? Please focus on points 1 and 2.
Other Names: heavy-tailed distribution, long-tailed distribution, , pareto distribution
  • Part 1: Description of Fat-Tail Distribution phenomenon in World Problems and Career Success in 80000hours career guide:
The guide is available for free download at https://80000hours.org/book/
"the most effective actions achieve far more than average. These big differences in expected impact mean that it’s really important to focus on the best areas. Of course, making these comparisons is really hard, but if we don’t, we could easily end up working on something with comparatively little impact. This is why many of our readers have changed which problem they work on. "p.60
"Each change took serious effort, but if changing area can enable you to have many times as much impact, and be more successful, then it’s worth it." (p.61)
"the top 10% of the most prolific elite can be credited with around 50% of all contributions, whereas the bottom 50% of the least productive workers can claim only 15% of the total work" (p. 89)

"Moreover, success in almost any field gives you influence that can be turned into positive impact by using your position to advocate for important problems (p.91).
This all also means you should probably avoid taking a “high impact” option that you don’t enjoy, and lacks the other ingredients of job satisfaction, like engaging work". (p.91)
"Finally, because the most successful people in a field achieve far more than the typical person, choose something where you have the potential to excel. Don’t do something you won’t enjoy in order to have more impact. " (p.95)

Figure: Actual Fat-Tail distribution of Careers (p.90)
  • Part 2: Significance of the fat-tail distribution especially for individuals (All points are comparing fat-tail to bell-curve) :
1. It seems to me that in both distributions we have a motivation to aim for the top (obviously the top would be better) but the nature of motivation changes.
The nature of the carrot and stick changes from "aim to be among the best" because
(bell-curve carrot): if you do great things will happen to you.
(bell curve stick): if you don't, you will remain in the average and mean range
To" aim to be among the best" because
(fat-tail carrot): if you do, VERY VERY VERY great things will happen to you.
(fat-tail stick):If you don't, you will remain in the average (BELOW mean)
2. The more variance there is in a statistical sample, the wiser it is to aim to move to the exploration direction in the exploration-exploitation (deliberation-action) spectrum (the relationship between variance and value of new information). In terms of career, the variance is great so the exploration investment should be great as well.
3. Median does not equal average. The average could be misleading and the median could be misleading
4. If all other factors are moderate or weak but you have a good reason to think you can reach the top, go for it because average can be misleading, your rank is as important as your field).
5. Choosing a job at random is not advised because the median is lower than we think.
6. Even though below mean is much more likely in this distribution, probability of being a hyper-performer is higher , which makes the hyper-performer goal a more realistic goal hence, it's easier to become motivated by it.
7. Looking at the outliers becomes more important because they become more influential.
8. Pareto principle (80/20) can encourage generalist over specialization because the effort you put in one field result in a better impact if distributed over many fields but at the same time it can encourage specialization over generalism because the pareto distribution makes you want to aim for the very top because its impact is disproportionate.
9. Does the long-tailed distribution favor an "all-star" "super-star" or "SWAT" team approach of fewer more qualified people (quality over quantity)?
10. Prioritization becomes more important?
11. We often behave as if the bell-curve distribution is true while it's not. So the significance lies in adjusting our behaviour?
12. Why does personal fit become more important under the long-tailed distribution? Because the long-tailed distribution has a higher variance. If success in a specific field had zero variance, then individual differences wouldn't matter much so the person-environment fit would not be v. important because as persons change nothing changes as a result. However, the reality is that there is great variance so individual differences matter a lot (how would you "react" to a field NOT JUST how good is a career).

I developed an instrument for measuring emotion perception based on the abilitybased model of emotional intelligence, with 3 types of items(scales): auditive , semantic and visual. I now need to select the items which fit best in to the model. Exploration and selection of the data with "typical itemanalysis" ( item difficulty and item discrimination) and followed factor analysis does not lead to best internal consistency (cronbach´s alpha) and factor structure. Is it possible to do factoranalysis first, select the items which best fit into desired factorstructure, by looking at the factor loadings? This is a very subjective approach, so are there any guidelines?
Relevant answer
Answer
Hello Anna,
Yes, you may first try factoring the items to see whether the anticipated scales emerge. Once those scales are identified, you could further refine them by looking at item analyses within scales. However, do recognize that the factoring step capitalizes on the observed relationships among the item scores, so item analysis estimates (esp. for discrimination, or internal consistency reliability) can be somewhat biased. For that reason, some folks would recommend separate or split samples for each analysis step.
Good luck with your work.

I want to start a philosophical discussion and ethical debate on the reasoning behind why humanity should and must become a multi-planet species.
  • What do you think is the most profound and captivating reason(s) that you have to justify SpaceX and Elon Musk's goal of making humanity a multi-planetary species?
Elon said during the 68th Annual ISC on September 29th 2017:
"I think fundamentally the future is vastly more exciting and interesting if we're a spacefaring civilization and a multi-planet species than if we are not. You want to be inspired by things. You want to wake up in the morning and think the future is going to be great."
I agree with him here, but I think there is something more profound and captivating that must be addressed with regards to becoming a species that lives on more than just one planetary body. Other questions we may want to consider to help us reach this answer include:
  • What are the ethical considerations we must address before colonizing other worlds?
  • Do humans really deserve another planet to potentially ruin, or even sustainably terraform, if we cannot even figure out how to sustainably balance our own home world?
  • One might ask why doesn't Elon use his genius to create new technologies that will advance the human race by solving some of the Earth's worst problems?
  • Has he simply given up on this planet and does he therefore want a clean slate to build up from?
  • Does Elon think that technological advancements resulting from the drive to become a spacefaring civilization (i.e. propellant production via. CO2 sequestration powered by 100% solar energy systems) will eventually rebound to help the Earth?
  • Must we start colonizing Mars now (i.e. beginning in the year 2022) like Elon's timeline suggests? Potentially, if we wait too long, technologies to reverse climate change on Earth may not have advanced enough without the excitement of being spacefaring...
Lets see what everyone thinks about this, and let's keep it civilized in here. Try and get real profound!
Relevant answer
Answer
If i may add my 5 cents to this:
  • What do you think is the most profound and captivating reason(s) that you have to justify SpaceX and Elon Musk's goal of making humanity a multi-planetary species?
--> Depends how you want to see Elon Musk: as the visionary who wants humanity to thrive and improve? Or just as the one who seeks fame and fortune for being the first in doing things?
In my humble opinion, humanity has yet to reach a level of mindset to overcome cultural and religious differences. We might have satellites and smart phones, but in our thinking we still behave like cave-men.
For example, the Americans, when setting foot on the Moon, put an American flag there. Not one showing Earth. How would it be on Mars, when Chinese, Indians, Europeans and Americans set foot there? Whom will it belong to? For sure not the entire humanity, so we would just bring all of our archaic thinking into a new world. All our problems and issues, and soon the new planet will suffer all the same problems as we have on Earth.
As long as we do not manage to live as one humanity on one planet (i.e. having a global government), there is no point in making humanity multi-planetary.
  • What are the ethical considerations we must address before colonizing other worlds?
--> As mentioned above: if you want to colonise something, who does it belong to? Is there indigenous life (whether intelligent or not)? Or is it a barren rock?
Now given the barren rock case: Who does it belong to? Imagine it has a huge amount of rare minerals on it. Is it "whoever finds it can keep it"? In the outer space treaty from the 1960s, they addressed this topic, saying that space belongs to all humanity, yet not all nations have signed this and yet when it comes to mining/farming/inhabiting these space environments, how is that regulated? And if violated, who prosecutes the violators?
There is a huge legal issue in regards to occupying space environments.
Now given the planet is not a barren rock, but an obviously inhabited planet: Now we can either develop yourselves as species and not touch the ecosystems of these planets, leaving them pristine for the indigenous life. Or we can act in the human way and do the same mistakes as we did in the past over and over again and just go there, exploit and trash the planet until its depletion.
The most difficult and realistic case is actually the case of Mars:
Why is Mars so interesting? Because in its past it was very similar to Earth, it had a denser atmosphere, a magnetic field, volcanism, starting plate tectonics, liquid water and all chemical ingredients for forming life. Mars might have gone through a similar evolution as Earth, forming microbial life, or maybe even be the origin of terrestrial life, as interplanetary transportation of rocks after impact events is proven to occur. Now, Mars is the perfect (and maybe only) place to actually study how life on Earth could develop and if life could develop on other planets as well, if life is unique or if it appears quite common throughout the universe.
But, if we send now a bunch of colonists there, who will bring lots and lots of organic material from Earth, we might spoil Mars to a degree where we cannot study this anymore, loosing a very unique opportunity.
Given the case there is still life around, wouldn't it be best to first study it, before building houses, schools and hospitals next to it?
And then there is another ethical consideration that needs to be taken into account:
Sending colonists to space with current technologists would use up significant amounts of terrestrial resources. Sending just 30000 colonists to Mars would already use up all the remaining mineral oil reserves on Earth, not to mention the metals, materials, supplies, etc shipped with the settlers. In order to send these few privileged people to Mars, the rest of humanity will have to sacrifice their lifestyle, their future and their environment. Is that ethical?
  • Do humans really deserve another planet to potentially ruin, or even sustainably terraform, if we cannot even figure out how to sustainably balance our own home world?
--> If we could terraform Mars, why not first terraform Earth? Reverse the effects of climate change, stop and reverse desertification. Earth is better studied than Mars, but as long as here high-ranked people make money with pollution and deny scientific facts, nothing will happen for the better. The money that Musk wants to spend on the colonisation could as well be spent to cover parts of the Earth's desert areas with solar power plants, providing humanity with CO2-free energy. That would benefit more people.
Also, terraforming Mars will not be sustainable. Mars is loosing its atmosphere, because of the lack of a global magnetic field. it might become a home for a while, but thinking into the far future, Mars will be back to where it is now.
Plus, how do we know we can potentially manage to create stable living conditions on Mars, when we are all about destabilising every environment we enter?
  • One might ask why doesn't Elon use his genius to create new technologies that will advance the human race by solving some of the Earth's worst problems?
  • Has he simply given up on this planet and does he therefore want a clean slate to build up from?
--> Maybe because it is easier messing up something new, rather than fixing something old?
  • Does Elon think that technological advancements resulting from the drive to become a spacefaring civilization (i.e. propellant production via. CO2 sequestration powered by 100% solar energy systems) will eventually rebound to help the Earth?
--> Musk's rockets use RP1 (refined kerosine) like all other rockets, and as long as this remains the cheapest fuel, nothing will change. Rockets are basically 95% fuel that is burnt. Using synthetical fuels is a huge cost factor. And especially since the CO2-concentrations (despite being high enough to significantly influence the climate) in the atmosphere are too low for economical use, I do not see any of this happening any time soon.
  • Must we start colonizing Mars now (i.e. beginning in the year 2022) like Elon's timeline suggests? Potentially, if we wait too long, technologies to reverse climate change on Earth may not have advanced enough without the excitement of being spacefaring...
--> No. We need to politically, economically and ecologically get our shit together first. We need to all reduce our negative imprint on the environment on Earth, foster international collaboration not wars, fear or hate, we need to change our thinking not towards maximising the monetary output, but in maximising our own happiness and humanity towards others.
Also, we should (must) explore Mars first. The right step is to first send a small groups of astronauts to carefully study Mars (and come back) over an extended period of time (~20 years) to really answer all our open scientific questions, before we can even think of inevitably spoiling the pristinity of the planet.
==> this would be the right way, and would avoid many of the mistakes that human explorers on Earth have done in the past (i.e. settling at their first arrival to a new place)

Perhaps Human base space exploration is going to enter into next generation. A good time to get commercial benefit from available & approachable "Wealth" in Space. NASA, SPACEX, European Space Agency and other organizations are trying to explore the potential benefits in space. In this regard, there are few questions;
1) What commodities can be consider as "wealth" in space ?
2) What natural phenomenon in space can come under "space wealth" ?
3) How human can get benefit from space wealth ?
4) What are different trades other than space-tourism, communication & weather-satellites can be possible ?
5) Any other aspects plz ?
Thanks

HI, I am interested in developing a Magnetrohydrodynamic Generation project, to generate electricity from a volume of gas currently being vented to the atmosphere at an oil facility. See figure Attached.
However, I have been investigating the State of the Art in this technology for some time and I do not find any recent projects. I have generally found information about plants built in the 60s, 70s and 80s. I would like to know if anyone can tell me if the research about this technology continue, and if somebody is building plants of this type anywhere in the world. Thank you

Hi,
I'm searching for literature that deals with the comparison of orthologs between diverse species (primitive-like vs modern organisms - e.g. immune proteins in hagfish compared to mammal counterparts). Particular interest in structures/functions/pathways that exhibit profound variety between orthologs.
Perhaps a vague request but this information is required for a conversation of evolution and how it can be explored at the level of the nucleotide. Thanks

Redis and Memcached systems performs well in hash based tables.
I am trying to explore the tree-based main memory databases.
Some researches wrote in their papers that they replace hash table with B+-tree in Redis.
But i can't find the resources about B+-tree based Redis on the internet.
I was wondering if it is possible that somebody could share the resources about B+-tree based Redis or B+tree based Memcached.
Thanks.

I think foraging tasks might be useful for your purpose; there are a lot of existing computerized versions and these usually have established methods, i.e. applying a simple model-based measure, to assess the degree of "exploration".

Exploring this question in my research studies
Relevant answer
Answer
My personal experience with war criminals (I interviewed quite a few) is that apart from few exceptions, such as vey young kids, they never really regret what they have done: the power and the thrill are too great. A suspended amnesty (something like parole) might be a good idea in the case of the lowest actors, but certainly not for the middle ranking operators (the organizers, such as Eichman) or the top ones (the commanders, who are the originators of the genocidal idea, such as Heydrich or Hitler). German experience after the war is that many of the operators of the SS and Gestapo found quickly a similar job in the STASI (so did the SAVAK's lower officers in Iran, who continued to apply their skills for the Mollahs); and those who did not spent much time in secret networks to help their peers find refuge in Latin America or elsewhere.
With regard to young kids, it is known now (see the works of Berthoz on vicariancy) that there are in human beings 2 windows for the building of the capacity to empathize with others, around 7 and 14 years old. Unfortunately, we are doing close to nothing to help former LRA or Khmer Rouges of that age to reinsert into society, and even less to prevent the brutalization (see works by Audoiun-Rouzeau and Grossman in particular) by organizations such as the LRA, Hutu killers, Jamaat, ISIL, Hamas, Hezbollah or the PLO from endoctrinating a new generation of fighters.
An interesting tool developed in situ has been the gacaca in Rwanda, which rely on local supervision, on the basis of admission by the guilty party.
I have a lot of documentation on that topic, since I have been creating a new science, Juripragmatics: why and how people communicate in the hearing room, on the basis of my experience as a linguist, lawyer, justice administrator and judge in those fields.

I have Landsat 8 downloaded from Earth explorer. The DN values shows 0-12189.7 for Band 2, 0-13479 for Band 4, 0-12323.5 for Band 3 …..How do I get the proper DN values?
Relevant answer
Answer
There is nothing improper about these values. The numbers are higher than those from previous Landsat satellites, because the sensor has higher radiometric resolution (can distinguish much more than 256 levels of gray in every band). Thus, it is not possible to store the values in 8bit integer numbers (0-255) without information loss, so it is stored in 16bit numbers (0-65535). If you want to compare for example Landsat 7 and Landsat 8 images, you would need to convert both to radiance or to reflectance, maybe do atmospheric correction, and still keep in mind, that even the spectral properties of the ETM+ and OLI corresponding bands are not exactly the same.

There is a shale oil exploration going on in the Bazhenov Formation in Russia. The conditions there are extreme. Moreover, reserves has been estimated in eastern Siberian wilderness too. I was studying about the details of the exploration done by the exploration giants of US and Russia in that area. I want to know that what are the methods or tools that are used for the detection or exploration of shale oil reserves in such extreme conditions.
Relevant answer
Answer
If this is an exploration well: during a drilling process, the shale may be detected by the cutting lithofacies and an increase of total hydrocarbons as detected by gas chromatography. Depending on the pressure regime and superimposed rock-type there might be changes in the rate of penetration or drillability.

Role ambiguity refers to the lack of clarity in the roles an employee is expected to fulfill. Since a worker needs to understand clearly what his or her role is, not clearly knowing what one’s role is may result in negative situations. In organizations, management should ensure that authority and responsibility should be clearly defined.
