Background: Intense and persistent exposure to indoor-air biological agents has been associated with the appearance of allergic diseases. Archives and libraries Indoor environments in tropical countries are an important reservoir of fungal propagules., Objective: To evaluate the degree of air pollution with allergenic fungi in a repository of frequently-manipulated documents., Methods: Air sampling was performed by two methods: active (biocollector) and passive (sedimentation plate). Fungi were taxonomically identified, and spores were measured to determine their penetrability in the human respiratory tract, and its impact on episodes of allergy., Results: In terms of concentration and diversity, the local environment behaved as a fungal propagule reservoir, which showed that there is significant health risk for the staff that manipulates the documents. Some spores were shown to be able to reach the lower respiratory tract when inhaled, which increases their allergenic and pathogenic potential. Aspergillus, Cladosporium, Penicillium and Alternaria, which are referred to as highly allergenic fungi, were prevalent., Conclusion: Aerobiological studies are a valuable tool for the treatment of patients with allergy to fungi and other disorders they produce.

In the last decade important results have been achieved with the usage of geostatistical methods for the solution of geologic and mining problems, particularly in the estimate process of resources in Cuban lateritic deposits. Their uses imply on the one hand, to master fundamental concepts such as: the semivariogram calculation and adjustment, the kriging estimate and the geostatistical simulation, on the other hand, it is necessary to carry out a suitable processing interpretation in each moment, which depends on the experience of specialists on the subject. In this paper, some comments are presented on the article Geostatistical models of the nickel concentration in the domain 7 of Punta Gorda deposit with regard to the geostatistical simulation.

The article discusses the La Habana 2016 workshop on writing scientific papers that was held in Cuba on March 9, 2016.

This paper aims to build a theoretical approach to the master lines of constructing the new Cuban tax law. This special tax regime allows the tax governance of several actors of the national economy directed to develop technologies, change of productive matrix and growth of Cuban science products' introduction in the Cuban enterprises net. We used the analysis-synthesis; induction-deduction; sociological; exegetic, and modulation theory as methods. The main results obtained provide the master lines for constructing a novel political approach towards future tax regime. The authors offer systematization of the Cuban economic scenarios and provide novel and practically instrumental suggestions for transforming the current tax regime. [ABSTRACT FROM AUTHOR]

Cuba is struggling with a growing environmental problem: the uncontrolled spread of the allochthonous weed species marabou (Dichrostachys cinerea) throughout the country. Over the last 70 years, marabou has become a formidable invasive species that poses a threat to Cuban biodiversity and agricultural productivity. In this paper, we present a free and affordable method for regularly mapping the spatial distribution of the marabou based on the Google Earth Engine platform and ecological surveys. To test its accuracy, we develop an 18-year remote sensing analysis (2000–2018) of marabou dynamics using the Valle de los Ingenios, a Cuban UNESCO World Heritage Site, as an experimental model. Our spatial analysis reveals clear patterns of marabou distribution and highlights areas of concentrated growth. Temporal trends illustrate the aggressive nature of the species, identifying periods of expansion and decline. In addition, our system is able to detect specific, large-scale human interventions against the marabou plague in the area. The results highlight the urgent need for remedial strategies to maintain the fragile ecological balance in the region. [ABSTRACT FROM AUTHOR]

A National Innovation System (NIS) supposes updated, continuous, and collaborative work between different agents, so the value chain approach fits perfectly with this NIS conception. The sector selected to illustrate our proposal is the biotechnological industry because of its structure in technology-based companies and its contributions to de Cuban GDP. This is the first research that works in a proposition of NIS for Cuba. The objective of this paper is to suggest a NIS for Cuba based on the value chain of its biotechnological industry. We follow a benchmarking methodology. First, we analyze nine international NIS experiences from developed and developing countries. Then, we highlight several items to be applied to the Cuban proposed NIS by analyzing five indicators: regulations, technology and innovation policies, financial systems, business activities, and research and education systems. The proposed NIS shows links between funding, production, service, and scientific sectors based on the biotechnological industry. It is considered beneficial for the three most important actors in a nation (companies, government, and society) because it allows a profitable and durable solution for economic and social troubles.

This paper studies the lyrics of reggaeton songs. Reggaeton is a popular genre nowadays, especially among young people. Its songs contain a very rich and sometimes surprising vocabulary. That was the reason for choosing this topic: to understand this genre of songs and their lyrics. Thus the purpose of this paper is to discover the meaning of the words used in the songs of this genre, to clarify the main vocabulary characteristics and to point out to the differences between the Spanish spoken in Latin America and Spain. In the analysis, specialized dictionaries were used to reveal the meaning of particular expressions. Attention was paid to expressions which are different from European Spanish as well as to English borrowings (anglicisms). Fifteen reggaeton songs from three countries (Puerto Rico, Cuba and Colombia) were chosen. Our findings showed that in each group (Puerto Rican, Cuban and Colombian), words typical of each of these countries were used in the songs. Anglicisms were also present, although to a different extent in each group. [ABSTRACT FROM AUTHOR]

Very little is known about the investment climate and operations of MNEs in Cuba due to limited data provided by the Cuban government. In this paper, we explore the investment climate in Cuba and identify factors that limit the activities of MNEs. We also assess the impact of the COVID-19 pandemic and the future prospects for MNEs in Cuba. Our research is based on questionnaires and semi-structured interviews in MNEs operating in Cuba. MNEs consider low macroeconomic stability, the impossibility of acquiring real estate, access to financing and the movement of capital, and profit repatriation as the most problematic factors for their business activities. On the other hand, IPR protection, corruption, the skills and education of the available workforce and the availability of electricity were assessed as the least problematic. Less than half of the MNEs interviewed found positive changes concerning the investment climate in Cuba during recent years. This implies limited prospects for economic growth in the near future.

In Latin America, distribution networks are mostly radial, with high energy losses, representing about 16% of the region's electricity consumption. In Cuba, one of the alternatives that has been proposed to reduce these losses is the distribution of photovoltaic (PV) power plants of up to 3 MWp in them. This paper presents a new hybrid optimization algorithm to localize and size PV power plants to minimize energy losses in radial distribution networks. The method localizes the power plants using Empirical Discrete Metaheuristic in conjunction with a novel strategy that reduces the execution time of the algorithm. The sizes are found using the Coordinate Search Method, which performs one‐dimensional searches in the directions of the variables of the objective function. The algorithm was run on a 33‐bus IEEE test system in which up to five power plants were optimally installed, taking into account load variations at the distribution level and changes in the weather conditions under which the power plants operate. It should be noted that the execution times for each scenario did not exceed 30 s. The algorithm was validated by comparing it with other methods found in the literature and proved to be more efficient than them. [ABSTRACT FROM AUTHOR]

The aims of this paper were to study the biofouling and biodeterioration of photos and maps stored at Historical Archive of the Museum of La Plata (HAMP), Argentine, and two repositories of the National Archive of Cuba Republic (NARC) and to carry out the physiological characterization of the isolated fungi and bacteria. The role of the environmental microbiota in the biofouling formation was also studied. Microbial assemblages in the air were sampled by sedimentation technique while those on documents were sampled by swabbering. Biofilm formation and biofouling were monitored by scanning electron microscope (SEM). Large microbial assemblages were found at NARC archives with the prevalence of genera Aspergillus, Cladosporium and Penicillium, whereas at HAMP these values were lower, Penicillium was the only fungal genus detected. Most of the fungi degraded cellulose and produced pigments and acids, and all of the isolated bacteria had proteolytic and/or cellulolytic activity. In all cases, a higher concentration of viable bacteria than of fungi was isolated from documents. These results correlated with bacterial values detected in air at NARC repositories. However, this correlation cannot be observed at HAMP where Aspergillus, Penicillium and Talaromyces helicus (teleomorph of Penicillium) were isolated. It is the first time that the last genus is reported in documents., (Copyright © 2011 Elsevier B.V. All rights reserved.)

Cuba's economy has fluctuated strongly due to COVID-19 and natural disasters. In addition, sugar production, which is Cuba's main export product, also fell sharply. In the absence of underdeveloped industrial technologies and digitization, Cuba currently has to allocate its resources with even greater consideration. That's why utilization and optimization of sugar production and transport can take advantage of its inherent potential and reserves. After presenting the history of sugar production and its current, mainly local, technology, we present three simple methods, which do not require very professional knowledge nor expensive software or hardware to optimise these processes. We recommend the establishment of basic collection points, which would operate as specific logistics centres, with the role of service provision and pre-production in addition to the collection. Also, the paper proposes a method that can be used to design layouts in 3D, making the current sugar production process more compact and efficient. [ABSTRACT FROM AUTHOR]

Background: This paper responds to Asante et al. (in Hum Resour Health, 2014), providing an updated picture of the impacts of Cuban medical training in the Pacific region based on research carried out in 2019–2021, which focused on the experiences of Pacific Island doctors trained in Cuba and their integration into practice in their home countries. Methods: The research focussed on two case studies—Solomon Islands and Kiribati. Study methods for this research included multi-sited ethnographic methods and semi-structured interviews as well as qualitative analysis of policy documents, reports, and media sources. Results: The Cuban health assistance programme has had a significant impact on the medical workforce in the Pacific region increasing the number of doctors employed by Pacific Ministries of Health between 2012 and 2019. Qualitatively, there have been some notable improvements in the medical workforce and health delivery over this period. However, the integration of the Cuban-trained doctors into practise has been challenging, with criticisms of their clinical, procedural and communication skills, and the need for the rapid development of bridging and internship training programmes (ITPs) which were inadequately planned for at the outset of the programme. Conclusions: The Cuban programme in the Pacific is an important model of development assistance for health in the region. While Cuba's offer of scholarships was the trigger for a range of positive outcomes, the success of the programme has relied on input from a range of actors including support from other governments and institutions, and much hard work by the graduates themselves, often in the face of considerable criticism. Key impacts of the programme to date include the raw increase in the number of doctors and the development of the ITPs and career pathways for the graduates, although this has also led to the reorientation of Cuban graduates from preventative to curative health. There is considerable potential for these graduates to contribute to improved health outcomes across the region, particularly if their primary and preventative health care skills are utilised.

Basketball is one of the students' favorite ball games, and it is also one of the most popular sports for college students to carry out after class. Especially in recent years, with the spread of NBA culture around the world and the extensive development of CUBA in domestic colleges and universities, Yao Ming has appeared in China to compete in the NBA and achieve brilliant achievements. With the increasing investment in the number of basketball venues, basketball itself, as a sport with low dependence on venues, equipment, and people, has the characteristics of economy, convenience, and remarkable sports effect compared with other sports. College students' basketball skills, basketball awareness, and love for basketball are increasing day by day. Attribute reduction algorithm is one of the core contents of knowledge discovery, which describes whether every attribute in the attribute set of information system is necessary and how to delete unnecessary knowledge. Based on the attribute reduction algorithm, this paper studies the early warning of basketball injury risk. The basketball injury can not only make athletes unable to participate in training or competition, but even cripple or lose their lives, which hinders the normal development of sports. Therefore, we should make a comprehensive and objective analysis of sports training to find out the causes of sports injuries, so as to prevent sports injuries. This algorithm takes the attribute frequency as the heuristic information and solves the attribute selection problem when the attribute frequency is the same. [ABSTRACT FROM AUTHOR]

The protection of forest cover in Cuba is a state priority. It is part of the state plan to deal with climate change. The purpose of this paper is to assess the legal risks associated with the protection of forest cover, which is essential to ensure the sustainability of hydrological watershed management in Cuba. The qualitative method of social research was followed. Techniques of content analysis, semi-structured interviews, and legal exegetics were applied. Geographic information system (GIS) and remote sensing techniques were also used to triangulate data and results. This article provided a robust analytical framework for generating innovative laws for land planning through a three-phase methodological design associated with configuring, interpreting, and applying tools for stopping deforestation processes based on watershed management. As a result, it was demonstrated that limitations reveal a deficient legal application with risk in the river basin, and a significant causal relationship between institutions and communities. Furthermore, the study indicated that although there are legal norms that regulate the protection of forest cover in the studied basin, its vulnerabilities generate uncertainty about the foreseeable results in management of forest cover. It is recommended that the Provincial Council of Hydrographic Basins include the design of legal risk indicators for forest cover management into the sub-plan for forest area increase. These recommendations constitute a set of related actions to improve the sustainability of the above-mentioned management. [ABSTRACT FROM AUTHOR]

Cuba and the U.S. have the oldest Academies of Sciences outside Europe. Both countries have a long history of scientific collaboration that dates to the 1800s. Both scientific communities also share geographical proximity and common scientific research interests mainly in Biotechnology, Meteorology, and Public Health research. Despite these facts, scientists from both nations face serious barriers to cooperation raised by the U.S. embargo established in 1961 that prohibits exchanges with Cuba. The study aims to analyze the effects of U.S. policy on scientific collaboration with Cuban scientific institutions. The results of the bibliometric analysis of Cuba-U.S. joint publications in the Web of Science, and Scopus databases between 1980 to 2020 indicate sustained growth of scientific collaboration between scientists of both nations over the past forty years. The results also show that after the 1980 Smithsonian Institution and the Cuba's Academy of Sciences agreement significantly increased scientific collaboration between U.S. scientists with their Cuban peers. President Barack Obama's approach to normalizing the U.S. Cuba relations in 2015 enhanced Cuban scientific production with U.S. scientists by exceeding the number of collaborative papers published during any preceding U.S. Presidential administration. By 2020, Cuba had expanded its scientific links to 80% of the countries in the world. Cuban and U.S. scientists converted from adversaries into partners, showing that science is an effective diplomatic channel. A particularly important question for the future is how robust is the collaboration system in the face of greater political restrictions? [ABSTRACT FROM AUTHOR]

This paper examines the way Cuba was represented in noticeable online media in connection with Bernie Sanders' aspirations to become the Democratic nominee for the 2020 presidential election. Traditional anticommunism and a historical one-sided view on Cuba in the press, as well as widespread conceptual confusion about "socialism" in US society, converged against Sanders over the run-up to the nomination, especially at a crucial moment in February 2020 when he was the frontrunner and was interviewed by CBS. The paper analyses the reaction of the online press to Sanders' comments on Cuba during the interview, but also considers other US press reports during 2019 as well as specialised literature on the topic. Discourse Analysis parameters are brought forward to highlight ideological discourse representations in the media. [ABSTRACT FROM AUTHOR]

Spirometra (Cestoda: Diphyllobothriidea) affects humans and some species of domestic and wild animals which eventually interact with humans. In this article, we report three new cases of Spirometra decipiens (Diesing, 1850) infection observed in two intermediate hosts and one definitive host, in Cuba. Genetic and morphological identification of S. decipiens in two snakes and a domestic dog were carried out by molecular means and routine histological study using hematoxylin–eosin staining, respectively. Taken together, the anatomical location, the host species infected with the specimens and their morphological and genetic features, all the samples were identified as S. decipiens. In each of the three cases, PCR assays using specific primers amplified bands that corresponded to S. decipiens species. To our knowledge, this paper is the first report of S. decipiens in species of Cuban endemic fauna and in the Caribbean islands. These species constitute a real or potential risk of transmission of Spirometra to humans in Cuba. [ABSTRACT FROM AUTHOR]

Recently, a trend towards increasing inequality has been detected in both developed and developing countries. Most of these studies have been focusing on formal monetary variables, since capitalism is a socioeconomic system where monetary relations play a paramount role. However, the distribution of non-monetary assets is also very important, especially so in less developed countries. This paper applies a PCA methodology to analyse the distribution of non-monetary wealth in Cuba, a socialist country where the role of monetary relations is relatively minor. Utilizing the MICS-UNICEF 'microdata', the paper provides for the first time an estimation of wealth distribution for three years (2006, 2011, 2014), by area and region. The main results show a non-monotonic wealth inequality reduction. The initial worsening (2006–11) is more than counterbalanced by a recent improvement (2011–14). [ABSTRACT FROM AUTHOR]

The student-scientific work (SSW) is an important component in the formation of graduate in the Biochemistry career that teaches at the Biology Faculty of the Habana University. SSW prepares the future professionals by performing research projects in inde pendent way, creating in them the values of teamwork and ethics. Beginning with second year and until fifth and last year of the career, students dedicate more than 1200 hours to SSW that culminates with the graduate thesis. This activity takes place at the research laboratories of the own Faculty and teaching units such as Center of Genetic Engineer and Biotechnology (CIGB), Center of Molecular Immunology (CIM), Finlay Institute, Pedro Kourí Institute (IPK), Center of Animal Healthy (CENSA) and Institute of Oncology (INOR), as well in other institutions such as Center of Immunoassay (CIE) y Hermanos Ameijeiras Hospital. Annually, students expose their research results in Student Research Journey of Faculty, where the most outstanding works are chosen in order to compete at Scientific Forum of Habana University and finally at the National Forum for Universities. It is interesting that many students develop their research in the immunology field or use immunologic procedures in other related fields. It is due to progress that Cuba has reached in the last decades in immunology and vaccinology fields. In this work we expose objectives, organization and evaluation of SSW, the participation of teaching units and other centers, results obtained in the last years of SSW and some opinions about achievements and deficiencies in this activity.

This concept paper builds on comparative work on sustainable agriculture in Canada and Cuba by exploring the role of agricultural co-operatives. Findings indicate that Canada and Cuba's agricultural co-operatives face the challenges of membership renewal and economic presence in their national economies. The paper argues that components of each agricultural co-operative system at the farm and tertiary levels could be adapted to the other nation's agricultural co-operatives in order to strengthen community control of local food systems. The paper further argues that a new approach to agricultural co-operatives must incorporate the state itself in any potential reform agenda in both countries. The paper calls for movement-to-movement contacts between the two countries, and the wider Americas. [ABSTRACT FROM AUTHOR]

One of the most interesting biological models is that of snail–trematode interactions, many of which ultimately result in the transmission of several important diseases, particularly in the tropics. Herein, we review the scientific advances on a trematode–snail system in which certain populations of Pseudosuccinea columella (a common host species for trematodes) have been demonstrated naturally-resistant to Fasciola hepatica , in association with an effective encapsulation of the parasite by innate immune cells of the host, the hemocytes. Emphasis is made on the molecular and immunological features characterizing each P. columella phenotype in relation to their anti-parasitic competence, their distinctive ecological patterns and the existence of a significant cost of resistance. An integrative overview of the resistance to F. hepatica through comparative immunobiology, genetics and ecology is presented to hypothesize on the possible origins and evolution of this phenomenon and to postulate significant roles for parasite mediated-selection and environmental factors in shaping and maintaining the resistant phenotype in the field. Lastly, clues into future experimental perspectives to deeply characterize the interplay between P. columella and F. hepatica and the immunobiology of the resistance are also included. The advances revised in the present paper are only beginning to unravel mechanisms of anti-parasite innate defense responses and their evolutionary bases, and can facilitate the development of prospective approaches towards practical applications of P. columella resistance.
