Question

Hello,
I'm currently writing an essay for a university assignment on whether a, presumably hypothetical, clinical trial is ethically justified. I see that the second of the 4 questions that the National Institutes of Health (NIH) prompts you to answer/think about when defining if a study is a clinical trial is: "Are the participants prospectively assigned* to an intervention**?" (https://grants.nih.gov/ct-decision/index.htm)
The question is then further broken down by explaining that "prospectively assigned" refers to a pre-defined process (e.g. randomisation).
The essay question I have reads as follows: An investigator plans to conduct a clinical trial in remote parts of Brazil and Mexico. The trial involves giving children with suspected cutaneous leishmaniasis (a parasitic infection) a newly developed drug treatment over a 3 week period and then collecting a series of samples from them, including stool samples. What ethical issues does this scenario raise, and are they acceptable?
If a researcher is looking to do a clinical trial on children in the rural parts of Mexico and Brazil, I imagine the sampling method here would come under the non-probability sample method purposive sampling (https://www.scribbr.co.uk/research-methods/sampling/) -- Does this still fit what "prospectively assigned" refers to, even if the subjects for the trial aren't randomly chosen?
Also, I'm guessing that the question Are the participants prospectively assigned to an intervention? in full means to ask, 'Are the participants, that have been selected by a method of sampling, assigned to an intervention treatment for the disease the trial is investigating?'
Sorry that this wasn't written very succinctly, it's my first time asking a question on the website and I've only begun my second year of university, so I'm still coming to understand various terminologies.
Relevant answer
Answer
As per your query it is prospective. Regarding the sampling purposive technique can be used but it is not the first choice here. For logistic reasons one could do so. I would go with random sampling if the study population is large enough and the disease is of high prevalance. If purposive sampling is used there is a chance of bias creeping in but unlikely to be an ethical issue unless its justified scientifically

In Mexico, as in other latitudes, the measures against COVID-19 have decreased and the governments and health entities of each country have applied their own criteria as a result of what they know and that their population tends to respond epidemiologically speaking. Do you think that the WHO should make the declaration that the pandemic has ended?
Relevant answer
Answer
The coronavirus situation is still easing worldwide with a weekly 18% cases and 23% deaths drop, though Asia is experiencing a surge in infections, especially in Japan and South Korea, amid two new Omicron subvariants.
Thus it will be too early to say Pandemic is ended.

Hello, can you help me please?
I'm working with plants, Jatropha curcas especifically, and i need to analyze some genes. The size of these is from 5 kb to 7 kb, and i need to get their nucleotide sequence. There is already a reference genome, but i only want the to sequence fragments of my interest, so i don't think that NGS is a good option.
By the way, i'm from Mexico.
Relevant answer
Answer
Did you mean that you want to sequence the entire gene in one go? I had previously isolated smaller fragments of 5-6 kb genes from Hevea using primers from the reference genome, then used thermostable PCR enzymes designed for longer fragments to amplify the whole gene from genomic DNA. Cloned the long fragment to plasmid DNA and Sanger sequenced the gene with the primers designed for smaller fragments. Alternatively can restrict (using restriction enzymes) the PCR-amplified whole gene fragment, clone to plasmid DNA and Sanger sequence it. Since you have the reference genome, it should be easy to decipher the gene sequence.

Has anybody done research on the possible relationship between the medieval taedium vitae, and the modern cultural fatigue? I touch upon this issue just passing by in a chapter entitled El ser para la muerte, de mi libro "Historia y Etnografía de la indumentari indígena en México"
Relevant answer
Thanks for your comment. Actually my interest started when somebody referred to an American anthropologist who used cultural fatigue to explain some social changes. I have rather related it to the philosophical development of existentialism, Heideggers death as justification for life, and Vattimo L´essere per la morte. I call that chapter being for death, as the English translation of "El ser para la muerte". In Medieval times apparently they had what they called taedium vitae, which I suppose is something like what you call burn out, depression, to languish, ,etc. I´m contending with the idea that being became associated with political power in a two thousend years process, and that truth has several forms of being expressed culturally.

I'm working on a study of how selection criteria of Tourism have changed considering Pandemic + Vaccination expectation, so propose a new prediction behavioral dynamic model for Riviera Maya (Mexico).
Relevant answer
Answer
Dear Carlos,
this is a very interesting and also important question. I think the whole tourism industry is looking towards this issue. Unfortunately, at least in my opinion, currently it is quite difficult to answer exactly, as the full ramifications of this extraordinary event are still not fully understood, also because it is still not concluded and new challenges are arising every day, such as mutations, forced closure of vital suppliers of the tourism value chains within destinations, extended quarantines upon arrival in the tourism destination as well as once returning home etc.
I can tell you about some trends we have seen in 2020 the region of South Tyrol in Italy (Italy - One of the countries, that has been most affected by the Pandemic in terms of Covid-related deaths in comparison to the population. Moreover, Italy is heavily depending upon the tourism sector) based upon arrivals and overnight stays. The main source markets of South Tyrol are Germany, the domestic market, and other surrounding countries (Austria, Switzerland etc.). Of course, I assume that the structure of source markets is very different from Riviera Maya, which probably has a higher share of international tourists.
After a good start in January and February 2020, Italy went into a complete lockdown during March and April, therefore the arrivals and overnight stays went close to 0. May and June saw a very slow increase, while July and especially August saw overnight stays which were close to the past "normal" years (August only -2,85% overnight stays im comparison to 2019). As the second wave approached during the fall, the numbers once again dropped. Here some insights and thoughts regarding the numbers:
February saw an increase most of all regarding German tourists, which can be attributable to the start of Covid-Cases around the world, and therefore international travels were partly substituted by travels to countries, which can be reached more easily by using individual means of transport (ex. car) which were and are still considered safer than public transport (during the summer months as well as currently also within tourism destinations, tourists oftentimes prefer avoiding public transport)
We saw that the increase during the summer months in the tourism numbers were mostly attributable to an increase of domestic tourism.
The length of stay decreased and overnight stays were concentrated more towards 4S- and 5-star hotels or tourist apartments. Here the perceived physical space at their disposal or the physical distance from other tourists seemed to play a role in the choosing of the accommodation type.
On a destination level, South Tyrol, being a mountain destination, seems to offer activities, which are more manageable from a crowding-perspective (ex. Hiking & biking), in comparison to sun & beach destinations, where tourist activities oftentimes are more static, which can result in crowds.
So, based on this information here some thoughts, which are partially related to points already made by other esteemed colleagues in their answers:
- Tourist behavior will be heavily influenced by their perception of safety and security, but also, by the accessibility of the visited destination upon arrival (quarantine restrictions, necessity to provide a negative covid-test, maybe certification of being vaccinated) as well as upon returning home (quarantine restrictions, necessity to provide a negative Covid-test).
- Tourism destinations, which are heavily depending upon international travel are more susceptible to the implications connected to this pandemic. In terms of destination management, a look towards the increase of the presence of tourists from the domestic source market, could help reducing the short-term-impact of international travel restrictions and the diminishment of international tourist numbers connected to it.
Reflections towards the destination to visit could encompass:
- Sun & Beach destinations oftentimes offer mostly static activities, which result in crowding. Tourists might increasingly look at the diversification of activities within destinations, with a special regard towards destinations, which offer activities allowing a greater dispersion of tourism flows (sightseeings, visiting the countryside, hikes etc.)
- Individual intra-destinational mobility options could also be an influencing factor regarding the tourists’ safety perception (presence of bike and car rentals in order to avoid the usage of public transport and therefore crowds)
- Accommodation of higher categories (4S and 5-star hotels) or private accommodation (tourist apartments, AirBNB) are perceived as being able to better offer more physical spaces.
Of course, these thoughts represent only some aspects, but I hope they can help you in your endeavour.

Answer
Dear Enrique,
thanks a lot for the answer. Very insightful. We are currently using Pemex Investor Presentation and Rondas Mexico (SENER, SCHP) data. We have estimates of 10.90 USD for 2017 and 12 USD (2018). Do you consider these average estimates to be realistic / "correct" (for Pemex)?
The comment on inflated costs at PEMEX is surely very valid. Yet, this is the way PEMEX operates and they have the bulk of the exploration and production activities. We are working on a paper where we aim at estimating the time span of operating crude oil production in Mexico assuming that production costs will rise in accumulated extraction over time (and might fall due to technical progress). In a business as usual scenario with no political changes, it is thus still valid to use their cost structure. If discussing the potential benefits of more private sector involvement then we would also have to use private companies' data. Yet, we concentrate on the former for now.
Nevertheless, do you have any contacts at Schlumberger or Baker Hughes that you could pass on? That would be very helpful.
Many thanks again.

However, I am a little curious and would like to know more about the features that can make it easier to determine whether a structure is or not a volcanic neck.
We center our concern on the following two questions:

Canada, Mexico and the United States recently signed a fresh overhaul of a quarter-century-old trade pact that aims to improve enforcement of worker rights and hold down prices for biologic drugs by eliminating a patent provision. The 1994 North American Free Trade Agreement (NAFTA) has been blamed for the loss of millions of US manufacturing jobs. The new deal therefore replace NAFTA, thus creating a new agreement called the US-Mexico-Canada Agreement (USMCA). The US and Mexico produced more stringent rules on labor rights aimed at reducing Mexico’s low-wage advantage, including verification of labor compliance by independent labor experts. Who stands to benefit most from this new deal and why?
Relevant answer
Answer
There are specific changes in the "new Nafta," apart from the name change, but their impacts are not expected to be great. Specifically, there are changes in labor and parts provisions in the auto industry, some strengthening of environmental provisions, more access for US dairy products to Canada, and an extension of copyright laws. There is also a new provision for review of the agreement and a limit (16 years) on its term. Mexico has ceded its sovereignty in regard to oversight of labor laws through its agreement to pass new labor laws with specified provisions and to allow foreign inspection of their implementation.

Relevant answer
Answer
It depends on the research purpose. If you would like to calculate trade balance, exp/imp ratios and so on, it is better to create two worksheets - for exports and imports (such structure makes it easy to quickly create new worksheets for each indicator you may need). Then you may put your data to the table with row names representing partner countries and column names representing years. If your research purpose would require some commodity breakdown, you may simply introduce the new column with commodity names (codes).

Answer
When calculating bioethanol demand, clean air and water polluted by petroleum combustion is difficult to evaluate health, economic, social, and climate affects. Although vehicle engines can burn up to 100% bioethanol, E85 is a more common substitute. Gasoline consumption by country (e.g. Mexico) is a good starting point to estimate bioethanol fuel additive potential. See https://www.indexmundi.com/energy/?country=mx&product=gasoline&graph=consumption.
Ethanol imports may also be used to track current use. See https://www.eia.gov/dnav/pet/pet_move_expc_a_EPOOXE_EEX_mbbl_m.htm.
Potential country use projections should also consider ethanol sources (i.e. domestic production and feedstocks) as well as international trade potential (i.e. exchanging petroleum for ethanol). International bioethanol projections for 2018-2027 can be viewed at https://www.researchandmarkets.com/research/chfwbr/global_fuel?w=5. A summary of Brazil's ethanol production and feedstocks can be viewed at https://www.extension.iastate.edu/agdm/articles/hof/HofJan09.html.
Using grains has been a common feedstock, but are costly to store and prepare since they must be taken to maturity, dried before storage, milled and rehydrated before fermentation. My patent eliminates those steps by turning green biomass into bioethanol and byproducts as a pumpable liquid within 24-72 hours after harvest. See .

Which option is most moral?
The long term consequences of the Mexican-American War of 1848 was the annexation of the northern half of Mexico. This (formerly Mexican) land became the states of Arizona, Utah, Nevada, and California. Today, the people living in these lands enjoy a material existence far superior to those people left in Mexico. So the moral questions we might ponder are:
Had the USA not annexed the northern half of Mexico, would the people of that country be living far better than they do now and would Mexico (twice as large as it is now) be far closer to the USA in military strength and GDP?
Or
If California, Nevada, Utah and Arizona remained part of Mexico, would all the people in those states be living in conditions close to that of the other Mexican people today?
Finally, would both the people of Mexico and those of USA be better off today had the USA annexed the entire Mexican nation in 1848?
Relevant answer
Answer
Well, the Mexican War happened. The per capita GDP of a Mexico that iincluded what was annexed by the USA, would be surely higher had there been no war, since the land is more arable. Part of the USA military strength, may be dependent on the apparent desire of the USA to be a large empire of influence over many countries. It has also been a source of strength in WW2 and to a lesser degree of "sucess" in other foreign affairs but often it has backfired and lessened the overall well being of Americans.and sometimes others. Does Mexico now or the Mexico with the Northern annexation have the desire for empire? Certainly not as much as the USA in either case. The military-inustrial complex (weapons companies) is one of the biggest factors in everything in the USA. Social programs, such as universal health care may be possible if the USA were not spending so much money on foreign interventions that have so little benefit for the American people and often very negative for the USA..

Recently, the president of the United States threatened to issue a tariff against Mexico if the government of Mexico doesn't help lower the number of illegal immigrants into the USA from Latin American countries. Do you think a tariff can be an effective government policy to persuade a border country to change their policy? Why or why not? Are there other real-world examples?

Paul: Thank you for your responses to my question! As most of you mentioned, a tariff is usually a tool to protect domestic jobs, rather than a punitive measure to punish another country.
However, since the time when I posted this question, Mexico has actually had high level talks with the United States. As a result, Mexico has agreed to do more to help stop the flow of illegal immigrants. See below link:

I acknowledge the fact that Mexico is not your traditional case of insurgency, but there are some factors to consider in this sense: the violence towards the Mexican government, police forces and citizens added up with the fact that the country is being ripped of economically (plus the considerable amount of time Mexico spent fighting cartels) by TCOs. I'm looking for help to narrow down my research puzzle as much as possible and correlate it with appropriate data/evidence. For example, would you analyse state's performative power in relation with TCOs activity? Any help appreciated.
Relevant answer
Answer
An interpretative case study methodology potentially based on the activities of one or two cartels. I'm looking for a theoretical link between Mexico's TCOs and their fit within a new model of insurgent criteria specific for the globalized era (commercial insurgency in which the distinction between classical criminal organizations and economic insurgents is blurred due to high corruption rates, which in turn favor for the preservation of parasitic societal conditions). By the way, I'm also inclined to include US-Mexico relations within the project. The study should be designed in accordance with political science conventions (Politi cs and IR;insurgency studies)

Bario is famous for its rice. However, one of Bario’s hidden treasures is its salt, made from salt spring but sold in very little quantities at the local marketplace that its existence is not commonly known outside of Miri, even for the Sarawakians.
From a geological prospective, the more intriguing question is - where is the origin of the salt? The Late Charles Hutchison had suggested an evaporate origin but I believe so far there is no detail scientific investigation has been conducted on the mineral and isotopic composition of the salt, nor the brine that may have geological and climatic implications and shed some light on the tectonic evolution of the complex Sarawak hinterland.
Therefore, it would be greatly appreciated if friends and colleagues in RG can share some thoughts on the subject, or point to any publication available for references of other altiplano or highland salts found in Latin America’s Bolivia, Mexico or in Tibet.

I have seen in the last decades in Latin America, that countries such as Brazil, Mexico, Venezuela, Peru and Colombia, have move to try to organize national systems of research, in which the classification of research groups as well of researchers, is officially made in a periodical way. E.g. in Colombia, research groups, after criteria-based measurement (based mainly in article and other products historic and recent performance), classifies them in four levels: A1 (highest recognition), A, B and C. Also researchers as: junior, associate and senior (highest recognition). Then, my question is in which other countries, a national science agency classifies and certifies the research groups and researchers officially?

I also asked a researcher in Mexico who has done extensive research on the K/Pg deposits, and he said that the measurements are done in the laboratory, so it is necessary to take a series of samples across the K/Pg boundary for analysis. It was also suggested that when taking samples, it is done with plastic or wooden tools since most metal tools contain some traces of iridium and can contaminate the sample since we are looking for concentrations in the ppb range.

Quezacoalt God promised to come back, bringing the red color to the Aztecs, which mean they didn't had bright red colorant. Hernan Cortes, who conquered Mexico, was born in Medellin, Extremadura, a zone where cochineals were raised, in order to do "kermes", the Arabic colorant for royal Spanish family (so Joaquin Cortez did not brought cochineal from America). As a matter of a fact, cochineal was even more valuable than gold in Europe, and did not showed off as much as gold: a brown almost dead insect thing you had to squash to get a bright red colorant. Spanish King didn't trust much Joaquin Cortez so he just allowed him 250 men to conquer an unknown territory. As far nobody believed in his project, imitating Hollanders, to raise cochineal in new territories, Cortez was rewarded the worst and sicker sailor men. Can you imagine those sick and feeble Europeans, in unknown Central America jungles, meeting an Aztec warrior and squashing with fingers a cochineal in front of his eyes, making the holy Quezacoalt color to happen? That's why Barbary (North-Africa) fig isn't called Chiapas fig, in despite of the roman-looking Aztec fresco describing an eagle on prickly pears. On the top of it, Spanish could pretend Indians were so stupid they were unable to squash a cochineal to get the bright red color and were stupidly waiting for Quezacoalt to bring it.

Question
18 answers
We know an earthquake is severe when it has a high magnitude number. The 1985 quake that devastated Mexico City was an 8.
In 2011, Japan was hit by a devastating magnitude nine earthquake which caused widespread liquefaction. The energy created by an earthquake starts to rock and jostle the layers of sediment and the structure suddenly collapses. This sudden collapse forces the grains of sand to push up against each other, which puts pressure on the water molecules surrounding the soil. To add to this, vibrations from the ground force the sand grains to keep moving around and around.
The combination of these two forces creates an effect similar to a sink hole - and the liquefied ground starts to swallow up anything that lies on top of it. Areas with a high water to soil ratio near coastlines, harbours and rivers were most affected by the phenomenon. 
Relevant answer
Answer
The simplest presentation of the concept of strength of shaking and the number of cycles is presented in what was published with the title "Simplified Proceedure for Evaluating Soil Liquefaction Potential" (Seed, H.B. and Idriss, I.M., Journal of Soil Mechanics and Foundations, ASCE, 97:SM9, Sept. 1971, pp. 1249-1273) This method and much of the fundamentals of earthquake induced soil liquefaction are summarized in "Ground Motion and Soil Liquefaction During Earthquakes." (Seed, H.B. and Idriss, I.M., Engineering Monographs on Earthquake Criteria, Structural Design, and Strong Motion Records, Earthquake Engineering Research Institute, Berkeley, California. 134 p.)
Liquefaction absolutely occurs without an earthquake trigger. There are a number of instances where tailings-ponds/settling-ponds have liquefied and produced an embankment failure. These events have been triggered by construction or production activities such as heavy-truck traffic or blasting. Any disturbance that changes the relative arrangement of loosely packed soil grains can result in the transfer of the stresses from grain-to-grain contact to the pore-filling liquid. Natural causes, other than earthquakes, tend to occur frequently enough that they keep significant amounts of material from accumulating that hasn't already been densified sufficiently to prevent future densification that would produce liquefaction.
In the case of storm waves, which you mention, the episodic increase of pore pressures by the wave-loading reduces the grain to grain contact stresses at the same time as vibrations from the waves can promote relative shifting of the grains. Quite often in these cases, there are additionally gravitational forces that are pushing movement down slope that contribute to the shift in grain interactions. Once the load is transferred to the pore-fluids, there is a dramatic reduction in shear strength.
