• A security specialist at Universidad de Santiago will be the only representative of Latin America in the UN Advisory Board on Disarmament Matters, which is made up of sixteen international experts on this matters.

Dr Lucía Dammert, a security specialist at Universidad de Santiago de Chile, will be part of the UN Advisory Board on Disarmament Matters. Early in January 2017, Dr Dammert received an invitation extended by the UN Secretary-General, Ban Ki-moon to become part of the Board.

The Board has the goal of debating and commenting on the UN decisions on nuclear disarmament, cyber-attacks  and small arms and light weapons control and it is made up of 16 experts from all over the world. Professor Dammert, a Peruvian security specialist, will be the only representative of Latin America.

“Most of the Board members are experts on this matter or renowned academics,” Dr Dammert says. They come from Australia, Croatia, Jordan, USA, Philippines, China, South Korea, Spain, France, Mongolia, Pakistan, Russia, Ghana, Norway and Finland.

With regard to her participation, she says that she will contribute from the Latin American experience. “I expect to learn from the different realities in other parts of the world and, particularly, to identify topics which are not currently part of the security agenda in the country or Latin America,” she says.

The Board meets twice a year, in Geneva, Switzerland, and New York, USA. “During these meetings, the Board reviews different issues on the disarmament agenda and debates on new global challenges,” she explains. After the meetings, the Board delivers a report with suggestions and recommendations to the UN Secretary-General.

Dr Dammert is a sociologist, PhD in Political Sciences and professor at the Bachelor’s Program in International Studies of the Faculty of Humanities, Universidad de Santiago de Chile.

She has a vast academic experience at universities in USA, Argentina and Chile. Her participation in the Board is not limited to a specific period, as it is an “open invitation in time,” she says.

• Universidad de Santiago’s interdisciplinary research team, led by Dr. Silvia Matiacevich from the Technological Faculty, is focused on developing an edible film that could increase the shelf life of fresh foods by 30%.

Improving the way of preserving foods has been a permanent concern in food industry. This is the reason why packaging is essential for the quality and shelf life of the product. But this packaging should be in harmony with the environment.

In light of this situation, a sustainable alternative for food packaging has been developed: food covering edible films, which are being widely used and have become a world trend nowadays. At Universidad de Santiago, an interdisciplinary research team is trying to replicate this development, giving value added to different national byproducts.

This initiative will be viable thanks to the Associative Dicyt Project called “Bioactive Coatings for Foods”, which gathers together experts from different faculties of the University.

“We will use food industry byproducts which are considered as dispensable or waste material. We are going to give them a value added by adding antioxidant and antimicrobial components to them in order to increase the shelf life of fresh food products,” Dr. Daniel López says.

Academics from three different faculties gathered for this purpose: Dr. Rubén Bustos, from the Faculty of Engineering (Department of Chemical Engineering); Dr. Diego Venegas and Dr. Marlén Gutiérrez, from the Faculty of Chemistry and Biology (Department of Materials Chemistry); and Dr. Daniel López and Dr. Silvia Matiacevich, from the Technological Faculty (Department of Food Science and Technology), being Dr. Matiacevich the leader of the project.

During the two years scheduled for the project, the researchers plan to study the synergistic effect of this combination of products and they expect to increase food shelf life by over 30%.

Interdisciplinarity

Most of the academics related to this project are part of a larger group created by the end of 2013 called Indi, Asociación de Investigadores por el Desarrollo e Interdisciplinariedad of Universidad de Santiago de Chile, a group of researchers that promotes development and interdisciplinarity at the university.

“All of us have participated in some of these initiatives at some point, seeking for this interdisciplinarity. This is how we have met other people and created contacts. What is good is that more than just admiring the work of others, we have the real possibility of conducting studies together. For this reason, we value this type of projects, as they promote the integration and interdisciplinarity that define a university,” Dr. Matiacevich says.

Dr Almendares presented the innovation in an activity devoted to the best sustainable development practices for food security.

Dr Laura Almendares Calderón, professor at the Technological Faculty of our University, carried out a technical visit to the Expo Milano 2015 (Italy) in order to get an insight of the food situation around the world. She was able to see a wide variety of raw materials, manufactured goods, equipment and supplies exhibited by more than one hundred countries. The activity had the presence of leaders from all over the world, like President Michelle Bachelet, who opened the Chilean Pavillion.

In this context, Dr Almendares, director of the FIA-USACH Project, PYT-2012-0033, “Development of a technology to replace prickly pear skin with a peel to keep the physiological, microbiological and organoleptic properties of the fresh fruit”, presented her work at the BSDP Week.

The activity started with an exhibition of photos, porters, brochures and other information material related to this matter. The academic was able to show the results of this Chilean innovative project to people from different countries, at the Urban Center, Galleria Vittorio Emanuele, in downtown Milano, between June 10^th and 13^th.

Chile participated in the competition “Feeding Knowledge”, a program created to contribute to the permanent legacy of the Expo Milano 2015.

With that purpose in mind, a document will be generated containing policies and key recommendations to create an effective knowledge system in the food security field in the Mediterranean Region. The final version of this document will be available in September this year.

Selection of proposals

The proposals submitted by eligible candidates underwent a strict admission control by the International Selection Committee, which is responsible for the final evaluation, using nine pre-established criteria.

The proposals that did not meet one or more of the admission criteria were not considered as “Good Practices in Food Safety.”

The ones that were well evaluated officially became “participating initiatives”, like the work presented by Dr Almendares. 

Her work was included in the priority theme “Food consumption habits: diet, environment, society, economy and health.”

This theme groups all projects which objectives are focused on research activities that evaluate the impact of current diets on the environment, economy, society, culture, health and nutritional sustainability.

This was the only Chilean study presented at the activity and it was registered as ‘9712. Development of methodology to replace prickly pear skin for enriched eatable peel. Chile. 25’.

• The projects supported by the Department of Agrarian Management of the Technological Faculty and the Food Science and Technology Research Center of Universidad de Santiago show important results, like a bio-pesticide based on residual quinoa grains or the potential edible use of this pseudo-cereal leaves.

The projects supported by the Department of Agrarian Management of the Technological Faculty and the Food Science and Technology Research Center of Universidad de Santiago (Cecta, in Spanish), show important progress in their goal of feeding the population in a healthy and equitable way.

The first project, “Biopesticidas en base a saponinas de quínoa” (Bio-pesticides based on quinoa saponins) (FIC 30343624-0) lasts three years and it is being developed in the O’Higgins Region, in Central Chile. It has the purpose of using the residual quinoa grains to generate a natural pesticide for grapevines.

The second project, “Valorización agroindustrial de subproductos de la quínoa” (Agro-industrial valuation of quinoa byproducts) (FIC 30429825-0), lasts three years and it is also being developed in the O’Higgins Region. The goal of this project is to promote the cultivation of quinoa, with new applications. Besides using the grains, they expect to promote the use of the leaves in salads.

The third project, “Habilitación de productores hortícolas de la región Metropolitana para la elaboración de productos IV gama” (Training vegetable producers of the Metropolitan Region in the elaboration of IV range products) (GORE BIP 30442786-0), lasts 18 months and it is the continuation of a project developed by the Cecta researchers in 2011 that tested different protocols to reduce the microbial load in vegetables like lettuces, cabbages and carrots.

Carlos Díaz Ramírez, Professor at the Department of Agrarian Management and Innovation Manager of the projects, explains that the purpose of this project is to train small farmers in the care and safety of all the production and supply chain of vegetables, until the products reach the consumer.

Some of the Cecta scientists involved in the projects are Professor Lina Yáñez Catalán, Dr Claudio Martínez and Dr José Luis Palacios Pino.

• Dr Manuel Azócar, professor at the Department of Chemistry of Materials of Universidad de Santiago was recognized as the best scientific publication reviewer in the Material Science Engineering C international journal. The expert is also a reviewer in other six different journals in this field in the United States, Asia, Europe and Latin America.

Dr Manuel Azócar, professor at the Department of Chemistry of Materials of Universidad de Santiago was recognized as the best scientific publication reviewer in the Material Science Engineering C international journal, for reviewing around 30 papers in one year.

He is also a reviewer for other six journals in the field for which he usually evaluates the standard: an average of 5 article submissions. However, for the journal that recognized him, he evaluated an outstanding number of papers, so it demanded a very intense work. He expressed his gratitude for this recognition and said that he has reviewed works from the United States, Asia, Europe and Latin America.

Dr Azócar has also published in the Material Science Engineering C journal since 2014 before becoming a reviewer.

He became a reviewer on his own merit, studying materials with potential medical applications, specifically metals like copper and silver, which have antibacterial properties to combat bacteria, viruses and fungi, among other microorganisms.

All the articles undergo an expert “blind review”. This means that the author does not know who is evaluating his/her article. The committee is made up of two reviewers and they decide if the article is accepted or not. If there is a tie, they may call for a third opinion.

Dr Azócar says that the process for the approval of scientific publications is very rigorous. “I rejected 60% of the articles. This usually happens, because in science, the standards to accept articles are very strict. Most of the article submissions are usually rejected for writing problems, poor contributions, and poor quality and lack of novelty,” he explains.

Scientific connectivity

The Materials Science and Engineering C: Materials for Biological Applications journal can be digitally accessed and Universidad de Santiago has subscribed to it, so academics can log in through the university account.

He says that information at a scientific level is increasingly democratising. “Many things have changed in science, like open access articles (PDF) which publication costs are paid by the authors and networking sites, like ResearchGate, a sort of “Facebook” for scientists,” he adds.

Goals and expectations

Dr Azócar expects to continue both publishing and reviewing at an international level. “Being considered at a global level is very interesting. They should know that there are people in Chile with a voice to give opinions on specific issues,” he explains.

He says that the journal has helped him in his professional positioning and career. “All these references help scientists to be good professionals, to be formally recognized and valued by the university. Besides, this benefits my future research work, because it gives me more credibility in my field of work. In the scientific career, the scientist is constantly growing up in time,” he concludes.

Providing basic knowledge about human cerebral cortex development at embryonic and early fetal stage is the goal of the research project led by Dr. Lorena Sulz, which will be conducted during the next three years.

According to reports, some psychiatric disorders, such as schizophrenia and bipolar disorder, begin during embryonic development. Most of the studies on this topic have been conducted on animal samples, due to ethical restraints and limited access to human embryos. This is the reason why the field of human embryology related to neurology is an area which has not been thoroughly explored.

In this context, Dr. Lorena Sulz, academic of Universidad de Santiago’s School of Medicine, will carry out the study “Role of nitric oxide in human cerebral cortex morphogenesis”, which intends to gather critical information about the mechanisms involved in the development of nerve cells during the first weeks of pregnancy.

The study will be conducted during the next three years and is funded by the Scientific and Technological Research Department (Dicyt) of Universidad de Santiago. It is a unique study as it is the first time that this branch of embryology involves human samples, which were obtained from de Institution’s Embryo-Fetology collection.

The idea is to gather basic knowledge about this topic in order to explain if the presence of nitric oxide is also essential for producing new nerve cells in human cortex, as it has already been proved in animal samples and in neuronal regeneration processes, both in human beings and mice. “We want to know if this molecule is expressed in the cerebral cortex being developed and identify in what areas and at what stages it is present. In this way, we can infer approximately the process in which it is involved,” the academic explains.

The study will be carried out in two stages. The first one will completely focus on the morphological analysis of cells and embryos being used. This stage, which is under execution at this moment, will allow describing the human cerebral cortex development process. After identifying each phase, the second stage will allow identifying cells that produce nitric oxide and the process in which it would be involved.

The study will be conducted at the Embryology Unit of the Faculty of Medical Sciences, Universidad de Santiago, led by Dr. Jaime Pereda, the project`s co-investigator, M.S. Carlos Godoy and Dr. Sulz. The three professionals, experts in their areas of research interest, complement each other’s work in a way that has helped to a good execution of their projects. “In general, the three of us work together because we use very similar techniques: only the molecule and the body organ of interest are different. We have adjusted to each other very well,” Dr. Sulz adds.

However, the expectations are long-term. The research seeks to establish some theoretical basis for human cerebral cortex development, in order to develop new studies on this topic. The results will be presented in different papers in specialized publications and in different congresses and conferences.

Finally, Dr. Lorena Sulz expects that during the research, they will be able to prove that nitric oxide takes part in human cerebral cortex development, just like it does in laboratory animals. “As it is basic science, it only provides a knowledge base. But if nitric oxide is known to be significant in cerebral cortex development, further care should be taken so as not to interrupt this process during the critical period, preventing potential malformations. This additional knowledge could be a contribution to prenatal care,” the researcher concludes.

• Professor Saúl Contreras, academic at the Department of Education, is developing the Fondecyt Project “Early Teacher Training for Science Education” that seeks to analyze the academic performance of 1,200 Teaching Training Program students across the country to contribute with an explanatory model on how future teachers internalize and implement their curricular teaching knowledge.
• According to professor Contreras, this instrument will put a strain on the Inicia Test,” because the latter evaluates future teachers at the end of their training. “Our idea is to evaluate students during all their training process,” to obtain a comprehensive and timely knowledge about it.
• Professor Contreras presented the first results of this study at international conferences in Tarragona and Barcelona, Spain.

The quality of education is today a core topic in the public policies debate and it has become one of the key demands of different social sectors.

But this quality is affected by different variables, like the good or poor education received by those who will be responsible for teaching new generations, that is to say, Early Teaching Training, (FDI, in Spanish). This is why Dr. Saúl Contreras, PhD in Education of Universidad de Santiago de Chile is working on the project “Early Teaching Training for Science Education”, funded by Fondecyt, that seeks to create a model and an instrument to evaluate the training process of pre-service teachers. As a result, this would allow training institutions to review the decision making process regarding training matters.

The study considers a national sample of 1,200 trainee teachers in math and experimental science specializations. The research team led by Dr. Contreras will do the corresponding follow up for four years.

“We seek to create a model and an instrument to explain how students acquire teaching competences and skills. In the context of the study, we are going to provide important data to each participating institution,” Dr. Contreras says. He adds that this information will be very useful to correct the course of early teacher training.

“It will put a strain on the INICIA Test”

Professor Contreras claims that among the side effects of this study, “it will put a strain on the Inicia Test,” the voluntary test to evaluate graduate teachers in different contents. “It does not make any sense to expect a quality education by thinking that we can achieve it just through measuring instruments like Simce, PSU or the Inicia Test.”

Professor Contreras also stresses that the Inicia Test evaluates pre-service teachers at the end of their training programs. “We propose to have a systematic assessment instrument during the whole training process and not only at the end of it. Because we should ask ourselves if the results of the Inicia Test are not good and the students already graduated, what happen to them? Should we give them remedial courses? It is too late to do it”, he answers.

For all the above, the instrument studied by this researcher at Universidad de Santiago de Chile becomes essential, because, according to Professor Contreras, it is not about preparing students like pre-university schools do: it is “creating and applying an instrument to evaluate future teachers at certain time points during their training. And this is a decision of the institutions that internally choose to help their students.”

Regarding the assessment tests, Dr. Contreras says that he totally agrees with their application, “otherwise it would be impossible to know how we are doing,” but these instruments should be developed “together with the subjects and starting with them, because they also need to be relevant,” he explains.

Professor Contreras is so convinced of the effectiveness of his proposal that he does not doubt that, after applying the assessment instrument for four years, it may be applied at a national level, in the context of a public policy. He thinks that it “can also be implemented in the technical- professional formation.”

Although the first stage of collection of data was finished only a few weeks ago- with the collaboration of teacher training programs of universities from Arica to Punta Arenas- professor Contreras presented the first results of this project at the International Congress of University Teaching and Innovation (CIDIU, in Spanish), held at Tarragona, Spain and then, at the Edulearn VI International Conference on Education and New Learning Technologies, in Barcelona, Spain.

These first steps allow seeing significant changes in future teachers’ training that, in the end, will affect the quality of education.

• The research, led by Dr. Miguel Maldonado, professor at the Metallurgical Engineering Department, intends to optimize this process through new on-line air measurement equipment.

During the last couple of years, we have heard about a decline in copper production, and according to experts this is one of the reasons why the quality of the mineral has been reduced. One way to revert this situation is improving mining procedures, which is a priority for mining industry.

One of these processes is flotation, a method used to separate valuable minerals like copper from others. The process starts once the rock is ground and mixed with water to form a pulp. Some reagents that modify the mineral surface are added to this mixture. In this way, when bubbles of air are forced up through the pulp, they collide with particles and the ones containing copper, for example, go up to the surface making a froth rich in valuable mineral, ready to be removed.

This is the method studied by Dr. Miguel Maldonado, professor at the Metallurgical Engineering Department. “Although today improvements have been made to flotation process- by means of devices that measure the air flow forced into a flotation equipment or the use of cameras that continuously monitor de physical properties of the froth- we still do not have a full knowledge of how air dispersion in the bubbles affects the metallurgical performance of the process,” the researcher said.

This encouraged the academic to do a research project called “Estimating on-line air concentration in flotation systems,” funded by the Scientific and Technological Research Department (Dicyt) of Universidad de Santiago.

“We believe that this variable is important when determining the process performance, as it is related to the surface area available to collect the particles containing valuable mineral and, therefore, to the complete recovery of copper,” the researcher explained.

The researcher said that the project was born while he was doing his postdoctoral research in Canada, at McGill University, considered a pioneer institution in proposing ways of measuring this variable. At that time, while he was studying this technique, he found out a problem with the interpretation of Maxwell’s equation, which would lead to a measurement error.

For this reason, the academic decided to insist on seeking new techniques in order to solve the problem; this time, with a better knowledge of the system.

At the first stage of the research, essential aspects of the error made will be studied. For this purpose, experiments to get a better understanding of the Maxwell’s equation will be performed. McGill University will also take part in this research by sending a flotation column to support the study and by developing papers together about this topic.

At the second stage, new techniques will be explored to find a method that estimates the air concentration in real time, in order to control and optimize the process.

In the academic’s opinion, “the efficient recovery of valuable minerals like copper is very important, and this measurement method could provide significant information for optimizing the process. This will have all kinds of benefits, such as reducing the reagents added or reducing the water used. This fact is also important if we consider that in most mining operations the water resource is scarce.”

• In order to meet the goals set by Universidad de Santiago in the context of the “Sustainable Campus” Clean Production Agreement, the University Social Responsibility program developed the first training workshop on this matter, oriented to students, academics and administrative staff.
• The initiative is one of the institutional actions to promote the knowledge on sustainability and to meet the goal of reducing the use of energy by 5% in the campus before March 2015, according to Santiago Peredo, RSU program’s alternate Director.
• The next workshop- on composting and vegetable gardens management- is scheduled for August. Also, the RSU program will hold seminars on the topics stemmed from the Institutional Sustainability Reports: human rights, decent work conditions, universal access to people with different skills, healthy eating and energy efficiency.

“People have become aware of environmental or sustainability matters. What we must manage now is to change some behaviors and develop some habits to be consistent with this already existing awareness,” Santiago Peredo, alternate Director of the University Social Responsibility (RSU, in Spanish) program said at the end of the first training workshop, “Self-diagnosis of energy use in buildings”, that was held by academics of Universidad de Santiago, on Friday 11th.

The workshop is part of the institutional actions to meet the goals set in the “Sustainable Campus” Clean Production Agreement (APL, in Spanish) of 2013, that seek to "promote training in this matter for professionals, students and academics of the University, and, in turn, to meet the goal of reducing the use of energy by 5% in the campus, before March 2015,” the RSU program’s alternate Director explained.

The workshop included two talks about energy efficiency. The first one was given by Professor Juan Araya, of the Bachillerato program, and the second one, by Professor Fernando Corvalán, of the Department of Geographical Engineering.

Professor Araya referred to the concept of sustainability in three interrelated aspects: environment, society and economy. The balance among the three of them becomes the sustainability equation. Professor Corvalán talked about energy efficiency in buildings, stressing the current actions taken in the building sector to save energy and the analysis of important supplementary aspects like heating, refrigeration and supply systems.

Regarding the campus, Dr. Corvalán explained that it was built according to standards that were not concerned for energy saving, such as the former EAO building and the buildings around the Planetarium. However, he emphasized that the new buildings mean an opportunity for energy sustainability.

Students, academics, professionals and administrative staff from the five units that voluntarily signed the University’s APL took part in the workshop: the Department of Geographical Engineering, the Technological Faculty, the Faculty of Administration and Economics, the Bachillerato program and the School of Architecture.

Waste management and vegetable gardens

“We prepared this series of workshops to meet the goals of training in sustainability and reducing the use of energy at the University, among others,” the RSU program’s alternate Director reiterated, as this is one of the actions established in the “Sustainable Campus” Clean Production Agreement.

The next workshop is scheduled for August and it will be about composting and vegetable gardens management, “because another goal is to reduce the solid waste produced at the University and this action could lead to new recycling processes that are not implemented now.”

“There are some initiatives to collect paper and glass in some recycling spots. We still have pending the organic waste treatment, as it is collected by an external service. The idea is that the University takes charge of the organic waste management and one way to do it is composting and the use of vegetable gardens,” Santiago Peredo added.

Pending tasks

Together with the sustainability workshops, the RSU program is planning continuous seminars that will include presentations and debates on five of the topics stemmed from the Institutional Sustainability Reports (2008-2012): human rights, decent work conditions, universal access to people with different skills, healthy eating and energy efficiency.

These five aspects are the ones that the reports have shown as weaknesses or needs. In these seminars open to the community that the RSU program plans to give every first Tuesday of the month (from August to December), the participants will evaluate the aspects that could be addressed in the workshops, according to the interests of the community.
