Chile - Science topic

Dear all,

I need the collaboration of native speakers of English around the Maule, Ñuble, Bio-Bio, Metropolitan or O'Higgins regions (Chile) as participants in my PhD. thesis. The participants will be asked to listen to and type recorded words uttered by Chilean EFL trainee teachers. The data collection could also be carried out online, but it would require the installation of computer software on the participants' PCs and copying some files.

Thanks in advance.

This is a methodological discussion on Lithium, which I pose in form of three open questions: 1) Who to trust when it comes to lithium reserves? Usually It is assumed that there are still no International certification processes but rather evaluations by some National Geological Agencies. Considering that we could be talking about a real sensitive issue, is it possible to imagine other reliable sources? 2) How to determine, rigorously, the commercial value of lithium and its evolution over time? Some apps and/or specialized webs calculate the price of lithium carbonate, even in a clic, although it is difficult to determine where there is exactly negotiated. Are there reliable alternatives? 3) How to calculate, prospectively, the strategic value of lithium? I'm afraid that some forward-looking calculations are excessively linear. Considering the uncertain environment,, is itn't possible to think in a some kind of a correction factor? I have some ideas but I would like to hear your qualified voices Thank you very much

Hi all, here in Chile we are facing a brutal shortage of consumables of Merck-Sigma-Millipore, specially after the fusion of Merck with Sigma and the pandemia, anyway the thing is that ultra filters from Millipore are taking 6 to 8 months to reach us! and we base many of our projects in ultrafiltration. The question es: do you know of a reliable (trsutable) substitutes for Amicon ultrafilters? Gracias

Hi, for a study I'm doing I need to get a view about the IO of the freight railroads transportation sector in Chile. Let me give you a bit of background. I'm just concern about the Railroad public company EFE (Empresa de Ferrocarriles del Estado) network, located in the center southen part of the country. There are two private freight operators which pay access charges established in two separate but equal acces contracts, which are regulated by EFE, a part of the contract) that follow the typical natural monopoly regulated price structure (a fix charge for right of using the rails, a variable chage in terms of kilometers of network usage and a variable charge in terms of volumes transported (TKBC, gross tons kilometers). In euros of 2014 per 1.000 gross tonnes, Chile's vharges (4 euros) was the fifth more expensive access charge compared to a large pool of european countries, and since then access charges has gone up and are currently in 5 euros per 1.000 gross tonnes. Although there are only two freight operators (yet it is open to more but have had no entrance since 2000, EFE operates only in the passenger segment) it is a very contestable market (trucks competition is ample and benefited from indirect government support). How would you be modelling a market like that? Bilateral monopoly with different bargainning powers? Natural Monopoly waters down and duopoly waters up (they curretly compete only in a fraction of the network but potentially all over)? or local monopolies water up? To add more complexity one of the freigth operators is vertically integrated with one important maritime port, and prevents competition from the other around that area. What reference you advice me? I need something simple, it is a study that is aimed at providing policy insight based on understanding the sector's IO, not on publishing an academic paper. Thank you in advance.

I did a cross-cultural study between Spain and Chile. The reviewers ask me to justify this selection. How would you do to justify it?

Thank you very much

Reviewing some samples of marine fouling from Seno Reloncavi, Puerto Montt, southern Chile. I need help with the identification of this organisms.

Brown-yellow color, shiny and inside it had epiphytes. In addition to amphipods in its structure.

I would like to discuss corruption and abuse within research and academia. I think many of us have suffered some kind of abuse or have been victims of corruption in research.

I would specifically like to share my experience with my master's thesis guide. She forced me to issue fee slips, where she told me to keep a fifth of the value and to deposit the rest of the money to her personal bank account. This money corresponded to the financial item destined to a research assistant, which in this case would be me. I found this practice very dubious, so I discussed this matter with her in person. When I discussed the matter with her, she got angry and told me that she had had to do that because there were some GPS that she had not been able to submit this expense for the project, because she had to buy them abroad. This seemed very strange to me, because after talking to colleagues who have worked on research projects in Chile, they told me that it is possible to submit expenses of this type of items. In spite of all this, I continued with my thesis, since I had already had two previous thesis themes that I could not continue to develop, for different reasons.

To my surprise, my guiding professor did not show up neither to my preliminary project defense, nor to my thesis defense. In addition, she told me that I should write my thesis in English (my native language is Spanish), since we had reached an agreement to publish my thesis in a scientific journal, and that if I did not write my thesis in English she would no longer be my thesis advisor. After I graduated from my master's degree, she told me that I had to do some extra analysis of my data in order to be able to publish my thesis. I told her that it was complicated for me, because I did not have a scholarship, and I had to start working to pay bills and other expenses. However, she threatened me that if I did not agree to do these new analyses, she would be obliged to publish my thesis by herself, and that we would have to "discuss later" the order of the co-authors of the manuscript, and it was likely that I would not be the main author. After this, I did not want to give away my work to her, so I did the extra analyses and worked as hard as possible to be able to publish the manuscript, working in parallel as an environmental consultant in order to finance my living expenses.

After publishing my thesis in a scientific journal, I reported my thesis advisor to the National Agency for Research and Development of Chile (ANID), because after talking to a friend that is a lawyer, he told me that what my thesis advisor was committing a crime: the illegal appropriation of public funds. Since the research project of which she was Principal Investigator was funded by the ANID (a Chilean government agency).

After this, I was contacted by a professor from the Universidad de Magallanes, which is the university where this professor who was my thesis advisor works. They did an online interview with me, and told me that they were conducting an investigation regarding my thesis advisor's complaint, and that if there was sufficient background, they would do a summary.

In January 2022, I wrote an email to find out if anything had happened regarding the investigation they have done on my thesis advisor, to which they replied that the process is not yet concluded. It has been 11 months since I was interviewed and more than a year since I made the complaint, and there is still no clear answer about the status of the investigation. This is really frustrating, as I had to go through both financial and emotional hardship due to this situation. It is unfortunate that these things happen in research and academia. However, I think it is very important that we begin to report these unethical and downright illegal practices, so that they do not happen again. I hope that my experience will help someone who is in the same situation and help them to make the decision to report this type of bad practices.

Hello,

To be sincere, I do not know if I can write this here, but I will try.

Some time ago, I have been working in order to understand and identify the drivers behind Land Concentration in Chile. Even though I have made progress, I am looking for a quantitative expert as a coauthor today.

The principal issue will elaborate an econometric model using the data collected.

If someone is interested just let me know.

All the best

A colleague is interested in the problem of mega-fires. If there are scientific papers for the United States, Australia or France, there is little research for South America. In France, a mega fire can be identified from 1,000 ha, in the United States or Australia from 10,000 ha.

Are there any studies in South America (e.g. Chile)?

Are there objective criteria for defining a mega fire?

Many thanks!

Hello,

I am currently developing a SDM for an invasive plant (Ulex europaeus) in Chile. I have 60 occurence points from the GBIF database and additional 40 occurence points placed by myself based on google earth satellite images. I developed four models: three models with 60 occurence points and different bias sampling methods (random background, target group sampling and presence thinning) and one model with all 100 occurence points (and random background). My idea is that the google earth analysis offsets the sample bias. To proove that I need to compare my models. Therefore, I use the continous boyce index.

The question I have now: Is it possible to compare the evaluation metrics of two models built with partly different occurence localities?

Hello everyone,

I am working on a project on maximization of water system performance in a river basin in Chile.

Now, I am looking for streamfow data for hydroelectricity production in the Laja river baisn. Could anyone please suggest a good source to download this data from year 1980 to 2010? Also, I am looking for turbine flow data for the same period.

Thank you in advance.

Hello all,

I am working on a WEAP model in a mountainous region in Chile. For this, I need data for snow accumulation gauge. The snow water equivalent data [mm] can be downloaded from the nsidc.org website in .hdf format. Can anyone please suggest me a way to convert the .hdf file to a csv file for WEAP? Is there other way to extract SWE in csv format like AppEEARS?

Thank you!

Asmita

Hello everyone,

I am currently working on my masters thesis to maximize water system performance in the Chilean Laja River basin under climate change. I need historical observed data for streamflow of the rivers Tucapel and Puente Perales. Similarly, I need snow accumulation data for the basin as well.

Could someone please kindly suggest, where/how I could find these data? Has anyone downloaded these data from internet. I would be grateful for any suggestions.

Thank you in advance!

Cheers

We've been writting to epsteineducation with no answer. Need delivey to Chile. Thanks for any info you can provide.

Hay dos pasantes que vuelven este fin de semana a Madrid, Marta y Lucia. ¿Tienes un grupo de Facebook para ex pasantes en Santiago de Chile?

I need to classify a group of participants according to their English language proficiency level. If anyone in Chile had a placement test I could borrow, I'd really appreciate it. Thanks!

Dear colleagues,

We would like to invite you to participate in a study that we are running together with the Federico Santa Maria Technical University (Valparaíso, Chile), the University of Concepción (Chile), the University of Valparaíso (Chile) and The Ohio State University (United States).

For this reason, I would like to ask for your help in answering this survey, which is aimed at:

- Professionals from any discipline.

- With at least one years’ experience in the professional field.

The project was initially considered for Chile, but now it will be extended to English speaking people worldwide.

The survey will take you no more than 15 minutes. This is its link:

It comprises two parts:

1) the first one asks about previous experience in design and co-creation activities, and

2) the second asks about the role of interprofessional work in specific situations involving the elderly.

Please, if you have never taken part in design activities, co-creation activities, or those related to the elderly, do answer the survey because this information is also very valuable for us.

I would also ask that you pass this survey on your colleagues, friends, and acquaintances because I am a little cut off in the academic world, and the idea is to cover the population in general.

If you can’t or don’t want to do so, I understand. For those who can, I truly thank you.

Thank you very much for your time!

The distribution of daily PM2.5 concentration (hourly) is bimodal in the city of Coyhaique (South of Chile). Coyhaique is the city more polluted by particulate matter accord the WHO. The major source of emission is the burning wood used for cooking and heating, principally at the night. The health risk estimation using longitudinal models could be biassed using the arithmetic mean each 24hrs as an exposure variable. Exist another function for PM2.5 different from the arithmetic mean?.

I am studying the prevalence of SARS-Cov-2 in a tertiary hospital in Santiago de Chile, my first data report an 11% prevalence in a highly complex hospital in the northern area of ​​Santiago. (Pre-print study)

Hi there,

I'm looking for one or several documents from a trustworthy source that describe the impacts of the 2017 wildfires on the water supply of Chilean municipalities, Santiago in particular. Documents in Spanish, French, or English are fine (I mean, I understand them :-))).

Thanks for your help.

My PhD includes a remote sensing survey of the Atacama Desert using freely available satellite imagery to detect archaeological sites. So far, I have not found any source of historical aerial photography for my area of study.

Dear R^G community, I am wondering:

Thank you all for participating, following and reading this discussion.

Thread upgrade: May 2020:

A year ago, I peer-reviewed a paper on the subject, it was about Chile role in data science collecting, since Chile grounds major observatories, it becomes a state policy to endure its participation. Then, I became a reader on the subject.

Dear community

Different models of these chambers have been installed in many countries in order to combat COVID 19. In South-America, such as Peru and Chile, mobile disinfection chambers have also been built. However, the respective health authorities have pronounced about it claiming that these chambers are not adequate, may harm people skin among other things, and may promote the infection at a faster rate. Finally, they added there is no evidence about their effectiveness. In contrast, countries such as China and Vietnam are promoting their use. What do you think?

Thank you for your opinion in advance.

I am doing research in confined masonry field where i need different western masonry building codes. If any one has access to them please share.

Dear all,

I would like to know your opinion about travelling by plane to go to conferences and actually the whole idea of having conferences where everybody in the world meet to learn what is going on.

I am very concerned as just some weeks ago I learnt that Greta Thurnberg decided to come to Chile BY SHIP to attend the COP25. After that I realized my already scheduled trip from Chile to an european country equaled 10 years of using my bike instead of driving my car.

In this context the question arises of should we scientist be promoting global meetings? How we can reduce our share? Should we make them more regional? How we engage more regions of the world that need to advance more in science and/or the ones that need more development and sustainable solutions but at the same time make the whole process more sustainable?

Personally, I feel I should not travel by plane any more, but it is a kind of selfish solution as I already had an important international experience. How we can provide that experience without large emissions or trying to avoid plane flights? I imagine that in some situations it is better that 1 person travels than 100, particularly if that 1 person can engage people to find solutions in the long term. Although in the same line I think I read James Hansen also decided not to travel at all by plane even though he would very likely be that 1 person.

I hope you take a minute to comment. I really think all scientific societies should take this question seriously.

Dear community,

I've been studying drug consumption and health events in Chile on individual-based approach from mutiple 7-year span datasets, so I want to publish a research protocol of my project, in terms of context, objetctives, methods, funding, ethics, analysis plan, etc. However, I found that many of the journals that publish protocols are mainly focused on clinical trials, so do you know journals that publish protocols of empirical studies based on administrative data?

Comparing the recent reforms undertaken in the health sector by the governments of Argentina, on the one hand, and Chile on the other and to evaluate the role played by politics in these choices thru the different implementation of the digital revolution in the last decades.

I refer to air pollution in the city of Santiago, which also has poor ventilation.

DNA now and archaeology shows a movement from the southern part of South America to Meso-America and long before it could have been possible for them to come from the north. Cocoa is three thousand older in Bolivia than among the Maya for one example. And of course Cape Verde in Chile.

El contexto STEM se especifica porque en estas áreas la matrícula de educación superior de mujeres es menor que de hombres, en Chile.

Hello everyone, I'm looking for some sources to write my thesis. The topic will be the role of the Catholic Church in Chile in 1973 with respect to the ruling power and the military. I'm interested in understanding whether and how the local Church was involved in the preparation of the coup and how it reacted afterwards. Thank you very much for your attention!

Climate change should have the potential impact on the fruit productivity in temperate regions

Does anyone know of any international seminar or international conference, where can I present my Phytostabilization Project for a tailings dam in Copiapó, Chile?

The species used in the dam was Schinus polygamus.

Hi colleages,

I am correcting a points in my manuscript in revision process.

i have a doubt about the n that i need to report in my table.

The data is the National health survey from Chile, but one of the problems with this data is strata is not specificed in the data and it is impossible to obtain.

For this reason, i am using this sintaxis in STATA to consider survey design in the results:

svyset _n [pweight=FEXP1], vce(linearized) singleunit(missing)

svy linearized : tabulate stress_financ Depression_1, count column

the results i obtaind with this syntaxsis are expanded, but i was thinking is better to report weighted but not expanded (how i can do it in STATA?) .

Or should i simply report raw "n"? I think this last option could be the best because readers could estimated power analysis or consider the real validity of result. For example, in this data two men are houseworkers and they had depressive episode.

Thanks for advice, whatever recommendations or reference about this issue.

We are interested in comparing patterns of plant species richness and endemism on geologically recent calcareous, coastal dunes in Mediterranean climate regions. Data are readily available for the Mediterranean Basin, the Cape, California, and South-Western Australia, but are sparse and difficult to access for central Chile. A key paper by Alexander Kohler was published in 1970 (citation below), but I have been unable to retrieve a copy thus far. I would greatly appreciate any suggestions of other data sources.
