Have SRL PRompt can enrich problem solving skills?
Relevant answer
Answer
Yes, SRL (self-regulated learning) prompts can help to enrich problem-solving skills. SRL is a process in which learners take an active role in their own learning by setting goals, monitoring progress, and adapting strategies to achieve those goals. SRL prompts are interventions or cues that support this process by encouraging learners to engage in specific self-regulatory behaviors.
Research has shown that SRL prompts can be effective in improving problem-solving skills in a variety of contexts. For example, a study by Hsu, Sharma, and Schaubroeck (2018) found that providing SRL prompts to medical students during a problem-based learning exercise improved their ability to diagnose medical cases. Similarly, a study by Pekrun, Elliot, and Maier (2009) found that SRL prompts enhanced students' problem-solving skills in a math task by encouraging them to set goals, monitor their progress, and adjust their strategies as needed.

How should international economic aid from developed countries to developing countries on the continent of Africa be developed so that, at the same time, the scale of international cooperation is increased, the scale of international coordination in solving global problems, e.g. those resulting from the progressive process of global warming, is increased, and with a view to achieving sustainable development goals?
How should international economic aid from developed countries be developed for developing countries on the African continent in order to make development more sustainable on a global scale and to reduce the disparities between the level of economic development, the level of investment in technology, the income level of citizens and their living conditions?
In pursuit of sustainable development goals, countries should cooperate, develop international trade and help each other not only economically, but also socially, in terms of food, medicine, dealing with the negative effects of natural disasters, etc. The issue of aid should be provided mainly by rich and highly developed countries towards economically underdeveloped countries. This support should be developed with respect for the cultural differences of other countries, so that economic aid does not turn into a new form of colonialism, i.e. without imposing a specific model of government, economy, culture, etc. on other countries. In this way, international economic cooperation and humanitarian aid developed in this way can be an important element in the realisation of sustainable development goals in accordance with the UN 17 Sustainable Development Goals for economic development on a global scale. The importance of the international and global scale of addressing the Sustainable Development Goals is increasing due to the growing scale and frequency of international or global economic, humanitarian, health, food, energy, climate and other crises caused by, inter alia, natural disasters, etc. In the years to come, the importance of the international scale of solving global problems with a view to achieving the Sustainable Development Goals will increase. The aforementioned increase in scale will be the result of an increasing number of different crises being realised on a global scale. These crises increasingly include the negative effects of weather anomalies and climatic disasters resulting from the progressive process of global warming. The process of global warming caused mainly by the fossil fuel-based energy industry still in place in some countries, motorisation powered by combustion engines, unsustainable production agriculture of livestock, unsustainable high-carbon construction, the use of outdated technologies for the transmission of electricity generated from combustion energy, etc., is a major problem. And this is just one of many problems that will grow in importance globally. The development of international cooperation and coordination of global environmental and climate policies, including the smooth implementation of the green transition of the economy, is therefore essential. Here, too, the rich highly developed countries should assist the economically weaker countries, inter alia, through the transfer of modern technologies. This issue relates, for example, to economic, medical, technological etc. assistance to poor countries in Africa. International economic aid from developed countries to developing countries on the African continent should therefore be developed, so that development is more balanced on a global scale and the disproportions between the level of economic development, the level of investment in technology, the level of income of citizens, in terms of living conditions, are reduced. In addition, international economic aid from developed countries to developing countries on the African continent should be developed in such a way as to simultaneously increase the scale of international cooperation, increase the scale of international coordination in solving global problems, e.g. those resulting from the progressive process of global warming, and with a view to achieving sustainable development goals. In this way, global development will be more sustainable, equitable, pro-environmental, pro-climate, etc. In this way, the solution of the global problems of the development of civilisation will be implemented to a greater extent in a more internationally coordinated manner and will be carried out more efficiently. Thanks to international cooperation developed in this way, globalisation processes will also be carried out mainly in positive aspects, taking into account the needs of citizens living in different countries. Attempts to use new forms of colonialism and activities involving the seizure of other countries' resources, theft of land and raw materials contained in the earth's crust, expanding the political sphere of influence, imposing a specific political system on other countries, and destroying a different culture are reprehensible, immoral, atavistic and primitive. The globalization of the 21st century should mainly concern the development of international cooperation, taking into account respect for cultural differences, other customs, a different system of belief, etc. tolerance for all differences. This is one of the key elements of respecting cultural, social, civilizational, and moral diversity, etc. In connection with the progressing global warming process and the need to counteract this process, the importance of developing international cooperation, including economic, humanitarian, medical, food, technological, etc. highly developed countries rich for economically underdeveloped countries will grow. This is related to the projected growing negative effect of the progressing global warming process, including, among others, intensifying and more frequent, more and more severe periods of drought, forest fires, arid soils, lack of fresh water, etc. A particularly high scale of occurrence of the above-mentioned negative effects of the progressing global warming process may, according to long-term forecasting models, appear in the future in tropical and subtropics, and thus also many countries in Africa. This is another argument for the development of the aforementioned international cooperation and multifaceted assistance for underdeveloped countries in Africa. In the future, globalization processes should be based mainly on the development of international economic cooperation, joint solving of global climate, environmental, economic and social problems, etc. development of global climate and environmental policy with respect for cultural differences, tolerance for other customs, value systems, cultural and civilizational diversity, etc.
In view of the above, I address the following question to the esteemed community of scientists and researchers:
How should international economic assistance from developed countries to developing countries on the African continent be developed so that development is more globally sustainable and the disparities that exist between the level of economic development, the level of investment in technology, the level of income of citizens, in terms of living conditions are reduced?
How should international economic aid from developed countries to developing countries on the continent of Africa be developed so that, at the same time, the scale of international cooperation is increased, the scale of international coordination in solving global problems, e.g. those resulting from the progressive process of global warming, is increased, and with a view to achieving sustainable development goals?

This requires concerted government measures with the societal efforts of civil society organizations, although we believe that this assistance will not be devoid of the self-interest of the developed countries, which will be framed in the form of agreements of economic dependence on African countries.

Understand the perceptual error as a deformation of reality. When something is perceived wrongly (deformation) or when something is not there (omission). Problem solving is the use of methods, in an orderly fashion, to find solutions to specific problems.
Relevant answer
Answer
Perceptual error can have a significant impact on problem-solving. When we have a distorted or incomplete perception of a problem, we may approach it in a way that is not effective or may overlook key aspects of the problem. This can lead to suboptimal solutions or even prevent us from finding a solution at all.
For example, if we perceive a problem as being simpler than it actually is, we may not allocate enough time or resources to solving it, resulting in an incomplete or inadequate solution. Conversely, if we perceive a problem as being more complex than it actually is, we may become overwhelmed and struggle to make progress toward a solution.
Similarly, if we omit important details or information about a problem, we may miss out on key insights or approaches to solving the problem. This can also result in suboptimal solutions or prevent us from finding a solution altogether.
To mitigate the impact of perceptual error on problem-solving, it is important to approach problems systematically and with an open mind, taking care to gather all relevant information and challenging any assumptions or preconceptions that may lead to a distorted perception of the problem. It can also be helpful to involve others in the problem-solving process, as they may bring different perspectives and help to identify blind spots or errors in perception.

Mathematics abstracted and idealized concrete mathematics, exemplified in Euclid’s The Elements. Religion around the same time or earlier, abstracted the concrete representation of deities. Are there similarities in the problem solving approaches?
Relevant answer
Answer
Plato, who preceded but for a couple of decades overlapped with Euclid, dealt in abstractions (e.g. forms) but seems to have swung both ways in respect of the literality of gods. However, Pythagoras preceded them both by several hundred years and advanced geometry from measurement practices to abstract generalizations. Yet he appears to have believed in the gods of the Greek pantheon. So it seems that abstraction in Greek mathematics emerged well before abstraction in monotheistic religion related phenomena. But these are vague observations. The concept of abstraction and how it applies in the two domains needs to be clarified before a plausible answer can be given.

Recurrent/routine skills can be defined as those that will be performed as rule-based processes after training, routine aspects, and, in some cases, fully automatic aspects. There are several constituent skills that may be considered recurrent in the literature-search example, including the use of thesaurus, the use of Boolean operators, and the operation of the search program, since these skills can be performed consistently in different problem situations.

Hello, I'm not in the pharmacy studies. But your question interests me because it looks like addressesing the intensity of problem solving in a profession. What is not problem solving versus what is problem solving makes it possible in a certain way to ask what is the level of task/competence concerned by problem solving competence.
To answer this question I quickly looked at what a pharmacist should do:
1 Pharmacy management
2 Patient relationship management
3 Supplier relationship management
4 Information and prevention actions for the population
5 Reception of students and trainees
6 Participation in studies and research
In this I have identified activities that do not concern problem solving in two directions:
1 and 2 : administrative management. With for example:
- Check the administrative compliance of the patient's prescription
- Identify the patient in the information system and if necessary create his file...
- Provide prescribed medication and do administrative registration
- Prepare the doses and check the doses
2: Organization of the pharmacy:
- Dispose/place equipment and products
- Open the door and close it at the posted opening times.
Even in these activities it is possible to have problems to solve. But it is for me in this type of activity of the pharmacist that the intensity of problem solving is the less important.

From Herder’s On the Origin of Language (Abhandlung über den Ursprung der Sprache): “... we perceive to the right and to the left why no animal can invent language, why no God need invent language, and why man, as man, can and must invent language."
When Shakespeare and Herder use the word “man”, do they mean every individual human being or all of humanity acting collectively are noble in reason (per Hamlet) or create language (per Herder)?

In the current COVID-19 crisis more than 380 thousand people died so far. Economy and mental health suffered tremendously. If there was an easy solution proposed in the very early stages of the crisis based on scientific findings by any scientist what would be the right course of action for other scientists and people in power of position?
1) Ignore that important solution and wait for the actual peer-review process to be completed. 2) Take initiatives individually and collectively on an emergency basis to explore the potential research and solution further. As saving lives are of absolute priority, a single day should not be wasted. 3) Resist that research and solution, as it is non-mainstream area and stop by any means even to send that research for the peer-reviewing process.

We introduce the concept of Proton-Seconds and see it lends itself to a method of solving problems across a large range of disciplines in the Natural Sciences. The underpinnings seem to be in 6-fold symmetry. This lends itself to a Universal Form. We find this presents the Periodic Table of the Elements as a squaring of the circle. It is rather abstract thinking, but just as the moment we define truth and as a result it reverses, I think we can treat problem solving this way: As Patterns…The idea is there is nothing we can say is the truth, but we can solve problems through pattern recognition. I would think this manner of problem solving through pattern recognition could be employed in developing deep learning machine intelligence and AI for its method of imitating human learning to gain knowledge.

Okay Stay but I think in order for a pattern to exist a theme must recur, therefor it has a characteristic by which it abides, so that is a restriction or physics in a straight jacket as Feynmann calls it. I think it is much like improvising on a musical intsrument, you have to develop your ideas according to a rhythmic cycle. The proton-second is an abstract idea that can be applied to large amounts of particles over macroscopic time periods. Alas the timescale of a second is characteristic of the proton, in this paper it determines its radius.

I tried to simulate many solar panels by SCAPS-1D, I get some results but many devices can't simulated because of divergence error. I tried to solve the divergence error by change some properties of front and back contacts, and adding some defects and recombination to all layers. The problem solved sometimes but but I'm sure that's not the right solution.
- what's the root of this problem of divergence?
- I need a direct guiding from You, please
- Tell me what is the best software for simulate heterojunction Solar cells?
- give me links of least versions of SPAPS and Silvaco
Relevant answer
I think the root of divergence of the solution lies in the numerical solution of the system of equations describing the mathematical model of the physical device together with the boundary conditions. Normally the mathematical operations require matrix inversion and in this matrix inversion the divergence behavior is imbedded. It is so that the such matrices contains elements with relatively large values and others which may be very small. If a large value is divided by a small value the result may be a large number that is out of the dynamic range of the computer. I observed this divergence behavior when solving large area thyristor where a region of the thyristor carries 1000A/cm^2 and other regions are off carrying a very small current in the order of 10^-12.
In my opinion one has to invent adaptive and smart solution methods that inspect the the possibility of divergence and and reformulate the mathematical solution to avoid such divergence. Smartness and adaptivity criterion must be found to such problems.

Dear Hadi Farhangdoust. Attempts at automatization design through a combination of patterns began in the 20th century, leading, as you rightly pointed out, to boilerplate thinking and step-by-step mass standardized design. In the middle of the last century, design mistakes were discovered in the mass products, designed for a typical consumer. With the development of graphic editors, it became possible to study demand in more detail and expand the number of participants in the design process. The resulting products, based on the qualimetric assessments of various experts, sometimes began to resemble handicapped, also far from the necessary needs of consumers. Today, the solution to the problem of low-quality design is seen in the use of digital technologies, This is the only new hopeful prospect. I sincerely wish you success in this direction.

Hi, in my study, I am examining what are the effects of a professional development program on students' problem solving and to what extent the effects of the program on students' problem solving is mediated by teachers' interactional time and instructional practices. In my data, there are five types of instructional practices (frequent data) and I already tested that the program has a positive relationship with teachers' use of instructional practices.
In the mediation model, do I need to extract a latent factor? or I can use them separately as five mediators.
When I use them separately in the model, three of them have a negative influence on students' problem-solving. It makes sense in a theoretical stand. For instance, more frequent use of supportive strategies (one type of instructional practice) has the danger of over-scaffolding students, thus it reduces students' problem-solving scores.

As low scores on the problem-solving inventory ( PSI ) indicate high levels of PSC, AAS, PC ( the three factors of the inventory).
My questions are:
1-Do low scores mean low arithmetic means?
2-Does the lowest value of the mean for a certain item within the factor means that the student possesses this trait to a large degree? Is the opposite true? ...
For example; after statistical analysis of the students' responses on item 15, which states “When considering solutions to a problem, I do not take the time to assess the potential success of each alternative” has got the highest mean (mean = 4.25, SD = 1.32), does the statistical mean for this item indicates that students have the lowest level of perception related to this item? the least mean was item 18, which states “When making a decision, I compare alternatives and weigh the consequences of one against the other” (mean = 2.84, SD = 1.82), does the statistical mean for this item indicates that students have the highest level of perception related to this item?
3-Which of the items in the inventory are negative and should be reversed in the statistical analysis?
I also applied the inventory after the study and noticed that the means were decreased in the post applying.
When performing a t-test, it was found that there is a statistically significant difference in total degree of PSI where t = 12.21 in favor of pre-questionnaire, also all t values for the factors were statistically significant in favor of pre-questionnaire.
Is the interpretation of this result correct, and that the perception of their problem-solving level increased after applying the module?

Hi everyone,
I work with the oospores (average diameter 27.7 µm) of a plant-pathogenic oomycete. In searching for antagonists of them, I incubate them with enzymes in solution or co-culture them with other microbes. I then assess viability changes using a combination of dyes - fluorescein diacetate and DITO-3 iodide.
My problem is that I always end up with a large amount of residual enzyme (and even buffer) or microbial residue in the tubes at the time of staining, which leads to many unexpected effects on the dyes (fluorescein diacetate in particular) and skewed results. I wash with sterile ultra-pure water and centrifugation twice before staining. I have tried adding more washes but it did not help and significantly increased the duration of the assay as well as increasing oospore loss (need to maintain oospore numbers for counting later on).
I have been thinking about filtration set-ups that might allow me to catch anything above, say, 15 µm and let through everything else. But I work with 24+ 1.5 ml tubes for each experiment, so the apparatus would need to work with this in mind and all the micro-centrifuge filtration options I can see are the typical 0.22/0.45 µm pore size (and would be a wasteful and expensive option anyway). Another limiting factor is the need to easily resuspend the oospores that I catch, in good numbers, to be stained. And this is a medium-throughput assay with small volumes, which also limits options.
I have also thought about flow cytometry/FACS, but the machines I have access to for these are on the other side of campus and would add an hr+ to an already long pipeline, where all I want is to reduce signal noise from residual enzymes. This option may be of more use down the line, when microbe-microbe interactions are a bigger focus.
Does anyone have any experience with this sort of very specific scenario? Or any ideas for how to more effectively wash my oospores clean before staining?
Relevant answer
Answer
You could collect your spores on the filters, then wash them as much as you want. Afterwards, you could resuspend them in a suitable liquid, then centrifuge them to remove the residual liquid. You would also need a vacuum device. I think it would still be difficult to get rid of all the bacteria this way, but it would probably work pretty well for the enzyme.
You could destroy the bacteria by treating them with lysozyme or a suitable antibiotic, such as penicillin. They would burst, making smaller particles that would be easier to filter.
You might be able to identify a potent inhibitor of the enzyme that you could add to eliminate any residual activity.

Hello,
I am a student and I have been trying to mesh this part but I am failing to mesh it with smaller elements because I get a warning that some of the marked elements are of poor quality (photo is attached). I have found out that if I make the curved outer straight the problem solves, but I am supposed to try to make this geometry work. So I am trying but failing. A finer Mesh doesn´t solve the problem. Sweep instead of structure does neither.
I use: nonlinear Geometry, Hex Elements structured (part is green), A Seed size of 1. It works with bigger seeds. And I use quadratic elements.
I think it is because of the complex geometry in that area but I am supposed to try to make this geometry work. So I am trying but failing. A finer Mesh doesn´t solve the problem. Sweep instead of structure does neither.
Honestly I don´t now how to solve this because of my lack of experience. I am just starting with Abaqus. My only idea is to partition this ares even further.
Is someone willing to help me? I would be very grateful!
Relevant answer
Answer
Solid elements in FEA are usually tetrahedral (pyramid) or hex (cube). It is preferable to mesh the part such that your tetrahedral elements to be like pyramids as much as possible and hex to be like cubes as much as possible.
The bad elements seem to be along the 2 sharp edges of the geometry. I think the sharp edges make it difficult for your hex elements to be like cubes. It likely needs to take one of the 12 edges of each cube and stretch it very far away from their centroids to create the sharp edge.
My suggestions:
1. Fillet the sharp edges. Normally sharp edges are not ideal from a physical point of view unless it is a cutting tool, plus it should avoid issues in meshing.
2. Try to use tetrahedral elements along the edges. This will result in a series of very "flat" pyramids along the edges, but you may have better luck than hex.

Geography has always been seen as a classical subject and rarely been linked to realised socio-economic development, or community’s problem-solving. The literature is scarce about the role of geography in overcoming challenges.
Here is however, one introductory paper for further readings
Relevant answer
Answer
Thank you very much Mohamed Buheji for the interesting question. I take the liberty of synthesizing Zagir Ataev 's great contribution - please correct my misconceptions -, "...geography provides an interrelated knowledge of nature, population, economy and the relationships between them, both of the country as a whole and of its individual regions, necessary for a wide variety of development problems in any country... I don't think there would be many more to add.
I add other questions in line with Mohamed Buheji 's: What are the theoretical economic frameworks present in the different spatial theories of geography or the so-called "new economic geography"? Do their contributions to socio-economic development go beyond merely identifying problems, such as determining economic potentialities, measuring socio-economic imbalances at the spatial level, among other contributions? We are waiting for contributions from colleagues who are working on these issues, to deepen.
Thank you very much.
Greetings
Fernando (From Argentina)
Muchas gracias Mohamed por la interesante pregunta. Me tomo el atrevimiento de sintetizar el gran aporte de Zagir –por favor corríjame mis equívocos–, “…la geografía proporciona un conocimiento interrelacionado de la naturaleza, la población, la economía y las relaciones entre ellas, tanto del país en su conjunto como de sus regiones individuales, necesarios para una amplia variedad de problemas de desarrollo en cualquier país…”. Creo que no habría muchas más que agregar.
Sumo otras preguntas en línea a la de Zagir: ¿Cuáles son los marcos teóricos económicos presentes en las diferentes teorías espaciales de la geografía o la denominada “nueva geografía económica”? ¿En sus aportes al desarrollo socioeconómico se traspasa la mera identificación de problemas, como por ejemplo determinar las potencialidades económicas, medición de los desequilibrios socioeconómicos a nivel espacial, entre otros aportes? Esperamos los aportes de colegas que estén trabajando estos temas, para profundizar.
Muchas gracias

I'm running a Waters UPLC-TQD system. I've been experiencing challenges with repeatability of peak areas across analytes , columns and methods.
I'm currently trouble shooting the issue. I'm running repeat injections of a Caffeine standard. The concentration is 100 ppb, injection volume is 10 ul. Areas start off being repeatable, then drop and change . Minimum value = 5455, maximum = 14419, median 13081. Signal-to-noise ratio is also all over with a minimum = 40870, maximum = 585158 and median =161406.
I've checked that there aren't pressure drops / spikes on the UPLC, no leaks that I can detect (pressure test passed, but I can't test up to the pre-column heater as I don't have a blank to blank off at this point). I've repeatedly primed and purged the injector, the purge solvent is mobile phase.
On the MS side I've done a resolution tune (passed) and have calibrated.
Any comments / suggestions as to how I can improve repeatability? %RSD = 25
Relevant answer
Answer
*I hope that you are not using the MS data for quantification as that can result in wide variability (due to non-optimized settings and the fact that most MS data is only used for qualitative ID, not quant). If you can not get a std such as caffeine to work perfectly, then there is no point in running samples.
General peak area or retention time variation problems that I see as a consultant are often caused by: methods that do not follow good chromatography fundamentals such as: use proper K primes; the column is not properly washed with a stronger solvent than used in the mobile phase after each analysis (leading to fouling); inadequate equilibration; integration settings are not appropriate; detection settings are not appropriate; sample preparation issues and/or lack of hardware maintenance. Troubleshooting must start with the basics (Instrument OQ and PV) and is something that can not be done via the web (only in-person, on-site, reviewing the specific equipment used and methods chosen). If possible, hire a local professional to review the methods and systems used. A second set of "eyes" on the problem can be very helpful to quickly find the cause.
Here is a link to a general article that addresses these types of common problems. Perhaps it will help ?

This question does not relate to philosophical romanticism applied to science that had some currency in the 1800s. Roughly it seems that scientific romanticism differed from enlightenment by inserting humanity into nature and seeking union via human consciousness and problem solving.
The romantic aspect of physics I allude to shares some features of the medieval tale relating to chivalry, such as Don Quixote and qualities of adventure into unknown parts remote from settled life, such as the adventures of Richard Burton, who translated the Arabian Nights.
The mystery is: how has nature contrived these things we observe?
The remoteness is that the answers may require extrapolation in size, microscopic or cosmological, or in length of time, short or long, or in eons past or yet to arrive, remote from human experience, or principles that defy and challenge human perception, such as universal gravitation, or the nature of time, curvature of space, or quantum particles.
The adventure involves all the steps to solve the problem.
It seems to me that theoretical physics is a romantic quest. If the physicist arrives at a partial or provisional understanding of some mystery, then that is a great romance.
Your view?
Relevant answer
Answer
Yes, I do agree to your observation. When physics leaves the experimental method, it is becoming romantic, either in formulating mathematical beauty or aesthetic texts. Such is the poetic consciousness of our physical universe, which is still a concealed mystery of dead and living matter.

The job market needs problem solving and innoviative graduates. Therefore need to instill students critical thinking at academic institutions. What's the best approach of instilling critical thinking on students?
Relevant answer
Answer
1. Formation of critical thinking is associated with the student's independence in assessing the situation. The teacher should not suppress the student's activity. The student must independently find a solution to the problem. The teacher should show the direction of the solution, but not the solution itself.
2. The formation of critical thinking is associated with practical activities. The student must learn to solve problems that are directly related to the surrounding reality. The teacher must explain that a person, nature or technology depends on the student's decision.
3. Formation of critical thinking is associated with responsibility. The student should not be afraid to express his own opinion and should be responsible for the decision. The teacher should give examples of responsible decisions.

Speaking about the benefits and disadvantages of public transport many responded that the most annoying things about this service are waiting time (frequency), the accessibility of the transport (especially for people with disability) and the number of transfers. My question is: What could be the solution to all these problems? We don't want to use private cars since that would lead to a traffic problem (which we want to avoid). Have you heard of any "collective transport 2.0" that could improve the existing one?
Relevant answer
Answer
The issue you propose is important, since the existence of an efficient public transportation is essential for the improvement of mobility and fluidity of land traffic. In this sense, and in relation to the issue of waiting time, it is important to achieve that public transportation adjusts to fixed schedules, and that such schedules are established in the most realistic way, since sometimes people know beforehand that they will not stick to the set time, which can logically bother users. Also, in those cases where it is difficult to establish fixed schedules, an app could be created that the user can have in his/her cellphone, and that will check in real time where public vehicles are, and therefore exactly indicate the time that the user will have to wait. This could also reduce the problem of transfers, since users would be able to establish their routes beforehand, and therefore adjust to the already existing transportations, thus reducing the waiting time between one and the other. Lastly, in relation to accessibility, it is necessary to provide enough measures so that any person, regardless of their conditions, may be able to access the vehicles. This function must be a responsibility of the very same managers of public transportation.

I am a medical student though neither virology nor pulmonology are my expertise. As the global community gradually adopts isolation and social distancing the concern now rises regarding the availability of respirators.
As with any specialized equipment simply commandeering a factory and ordering it to manufacture respirators is not a reality: machines must be retooled, programming written, quality control perfected. It could easily take months before any functional respirators are produced under these circumstances.
While the needs would not be perfectly addressed, in the spirit of working with what is already on hand: would a CPAP machine be able to step in and provide O2 support for someone in mild-low/moderate respiratory distress?

CPAP would not suffice for someone requiring intubation but it may work to support a high risk/vulnerable patient in the early stages ensuring appropriate oxygenation and (possibly) shortening/bypassing the acute phase further exacerbated by low O2 saturation.

The anaesthetic and portable ventilators are not as effective as intensive therapy unit (ITU) ventilators. Rather than using the same settings as we would with ITU ventilators, I therefore recommend that we adjust the settings on these ventilators according to frequent measurements of oxygen saturation, end tidal carbon dioxide, arterial blood gases, lactate and haemodynamic parameters. This is labour intensive and will require the assistance of staff who regularly care for ventilated patients but do not routinely work in ITU (i.e. anaesthetists).
So, as the COVID 19 pandemic progresses we will need to upskill colleagues to facilitate the assessment and treatment of critically ill patients with and without COVID 19. This may be achieved by face-to-face education sessions. However this is very labour intensive and may result in spread of COVID 19 amongst healthcare professionals.
An alternative approach would be to use standardised checklist proformas for the assessment of critically ill patients (see link below).
The use of checklist proformas can facilitate the management of critically ill patients by staff who do not routinely work in intensive therapy units. This could improve outcomes in this high risk cohort of patients and improve the confidence of staff redeployed to ITU from other care areas.

Nowadays, many researchers argue that systems can behave intelligently. Their argument is that eventually it is a necessity since, without intelligence, systems will be like a psychopath, which has problem solving capability but do not have rational purpose and associated responsibility. Others argue that, even if a system has intelligence, it will be very different from human intelligence since it will be not interwoven with feelings and emotions. Furthermore, behavior of the system may turn out to be emotionally, axiologically and etiologically deviant or even incorrect from an anthropomorphic perspective. Of course, feelings and values are important parts of human intelligent behavior. This entails the question: Let us assume that (i) intellect (intelligence), (ii) awareness (restricted consciousness), (iii) responsibility (attitudinal accountability) and (iii) reflective emotions (affections) are computationally reproduced (no matter whatever way).

Philosophy of the sciences
The hypothesis I make here is that if you understand the philosophical background of your scientific field of study, it will help you in doing better research, in the problems you solve, the questions you ask at the problem solving, in the way you approach problem solving, the tools you use and the way you communicate your results. Maybe it also help to determine how you behave in life, also here on the platform.
The philosophy of science looks in a rational way at aspects such as existence (ontology, metaphysics), knowledge (epistemology), methods (logic and language), values (ethics) and the beauty and creation of their truth (aesthetics).
In general, science is divided in three branches: formal, natural and social- and they again are divided into sub-branches with everyone their own way of thinking, their philosophical approach. Therefore, you have e.g. the philosophy of economics, the philosophy of physics, of art, technology, history, mathematics, business administration, engineering and so on.
People in the same field of study can differ of opinion about the philosophy of their science. Understanding the philosophical approach of other scientists and researchers here on the platform can help improve the communication.
Dear colleagues, maybe you can help answering this question: What is the philosophy or your scientific field about and how do you practice that philosophy doing your science?

I have 5 independent variables and two of them can work with mediator(unlearning) if I test independent variable individually, but if I put them together into a box together to test with mediator, mediator failed to mediate the realtionship between independent variale and depedent variable.
Thanks a lot.
