Resumen
Denialism is a social phenomenon that has gained relevance in public debate thanks to the digital context. The expression designates a systematic rejection of scientific or historical evidence, which seeks to influence public opinion to favor certain interests. The purpose of this work is, on the one hand, to characterize the denial phenomenon and, on the other, to offer an overview of the heterogeneity of substantive repertoires, narratives, purposes and underlying interests. To do this, we will analyze Holocaust denialism and climate denialism, as models of more sophisticated denialist discourses.

Resumen
The concept of disinformation, and specifically that of disinformation strategies, has been gaining notoriety in public debate. Its multidimensional nature and massive use has prevented a unitary and consensual definition. In this framework, the aim of this article focuses on delimiting the term by examining the bases that favour disinformation, the ecosystem that makes it possible and possible solutions. Finally, future lines of work for the study of this phenomenon are proposed.

Resumen
A sociological approach to podcasting as a multidimensional contemporary concept. The podcast in its form, interactively links design, collaboration and creativity in the creation of the so-called cultural content. Overall, this article presents five conceptual hypotheses concerning the most plausible ideas in understanding what kind of "creature" the podcast is. The first hypothesis is a sociological interpretation of the new media. For the second hypothesis, we attempt to trace the interpretation techniques so far prevalent of podcasting. The third hypothesis delves on the execution methods. The fourth one posits the intellectual uses and its political dimensions. Finally, we pose questions relatively different to the immediate past: what is the relationship between the "New media" and social research? Concluding with a final question: How does the podcast helps us to envision our modern world?

Resumen
The dynamics of a new segment of tourist activity bases its action on creating a link between the subject, the experience and the environment, these are the most important conditions for the tourist to choose the destination to visit. Environmental education within ecotourism is a strategic tool to promote respect for wildlife. The objective of this work was to develop an analysis of the impact of environmental education on the conservation of sea turtles in Mazatlán, Sinaloa, Mexico throughout three decades of recorded biological data in order to promote sustainable tourism with more socially solid attitudes. In Mazatlán Sinaloa, every year, during the sea turtle nesting season (July-October), numerous ecotourist subjects are interested in these endangered reptiles, in order to help protect and conserve these animals. There are regional and federal government public institutions that have a role in environmental education and wildlife conservation. This work involves the approach of animals on a coastal zone on the beaches with tourist dynamics with anthropocentric predominance with the aim of educating various social actors, where the natural resources that are the object of this investigation are sea turtles called olive ridleys Lepidochelys olivacea (Eschscholtz, 1829). The Mazatlán Aquarium with its sea turtle conservation program has managed to protect 15,103 nests; 1,393,194 eggs; 1,103,006 turtles released; 70.2% survival and 290,188 deaths due to natural disasters and other causes. Tourism supported by environmental education promotes an influence on residents and tourists for the care of the natural heritage of natural resources such as marine turtles. This research is a multidisciplinary analysis of the educational, biological, and sociocultural sciences based on a documentary review with in-depth interviews with key actors. There is a conceptual interpretation where social actors learn about biology, conservation, threats, and respect for wild animal life during their visit to the Sinaloan port.

Resumen
Invasive species are animals, plants, or other organisms transported and introduced by humans in places outside their natural distribution area and that have managed to establish and disperse in the new region, where they are harmful. The objective of the research was aimed to propose a system of workshops to contribute to the knowledge of Invasive Exotic Species (IES), and their undesirable effects on vulnerable Cuban ecosystems and in particular on the bird species Molothrus bonariensis (Gmelin, 1789), 8th-graduate students of the Basic Urban Secondary School "Fe del Valle". For the effective development of this research, methods of information gathering and processing were used in their dialectic interrelation, which allowed us to verify fy existing deficiencies in terms of knowledge of IES and their undesirable effects. The research represents a novel way of appropriating new knowledge about M. bonariensis among the 8th-grade students studying in that school. In order to mitigate the difficulties detected, the workshop system was developed and submitted to the criteria of experts who evaluated it as pertinent. With the implementation of the system, it was possible to verify the progress achieved by the schoolchildren in the knowledge of M. bonariensis as an IES.

Resumen
The phylogenetic assembly rule has received particular attention in its application in biological assemblies, and the present study aims to apply the use of this concept in studies of Neotropical plants associated with aquatic environments. Thus, species information was compiled from the scientific database Scopus, including information for 2813 aquatic and border spermatophytes and their types of dispersal syndromes from 76 assemblages distributed across the Neotropical. We constructed phylogenetic trees for the Neotropical region and for each province separately to define the structure of the ancestral relationships of the species in those assemblies by calculating the phylogenetic metrics of the singularities of each component of diversity and conducting multiple regressions of each phylogenetic diversity metric against environmental variables that represent the hypothesis of determinant contemporary processes. The phylogenetic structure was maintained within the context of species observed in the biogeographical provinces. The multiple regressions indicated no relationship between environmental variables and the predictor’s richness and phylogenetic diversity. It was found that most of these species disperse by anemochory and endozoochory, which can be important historical indicators for explaining the phylogenetic pattern displayed. More phylogenetic structure occurred in arid regions as opposed to the most phylogenetically aggregated species occurring in humid tropical zones. It was concluded that the Neotropical floras were dominated by non-random assembly rules, with a tendency to be composed of the same clades, independent of geographic distances; however, they demonstrated a tendency to form assemblies themselves into more congeneric or co-familiar forms rather than random associations. This phenomenon may be related to the types of dispersal syndromes of ancestral lineages. The Neotropical aquatic and border Spermatophyte were dominated by non-random assembly rules, with a tendency to be composed of the same clades, independent of geographic distances. This phenomenon may be related to the types of dispersal of ancestral lineages.

Resumen
Most Vibrio species identification methods take many days to deliver results, therefore it is important that research can be done on rapid and accurate detection and identification techniques. MALDI-TOF MS has proven to be a simple tool to identify and differentiate pathogens. The objective of this research was to recognize the available bibliographic information on the identification of Vibrio cholerae species non 01 non 139 of environmental origin by MALDI TOF MS. The Vibrio genera includes more than thirty species found in aquatic environments, some species cause diseases in both marine and human species. One of these organisms is V. cholerae, one of the most important species due to the production of cholera toxin (CT) which interrupts the transport of ions in the cells of the intestinal epithelium. The number of case reports involving V. cholerae no 01 no 139 in extraintestinal infections and potentially fatal bacteremia in healthy patients has increased and, despite the existence of molecular identification techniques such as PCR, sequencing, and gel electrophoresis pulsed-field, the MALDI TOF MS technique has been gaining ground in bacteriology laboratories in hospitals due to its speed and ease of use. There are studies that cover the detection of V. cholerae in MALDI-TOF MS, focusing on food and environment, however, when performing the search key, no specific studies on the detection of V. cholerae non 01 non 139 of environmental origin by MALDI TOF MS were found with the exception of a case report, presence in blood isolates, reviews of reports that indicate the importance of these microorganisms in the cause bacteremia and the importance of this technique for the future of bacterial identification. Therefore, is recognized that there is a need to continue producing new information to contribute to the implementation of genomic surveillance capable of predicting future epidemic outbreaks.

Resumen
Breast cancer is the second most common malignant neoplasm in women and is a global health problem. A developmental, longitudinal, prospective research study was carried out in the family doctor's office 31, of the 50th Anniversary Polyclinic of Nicaragua, Cuba from January 2018 to January 2021, with the objective of designing an educational program for the control of risk factors. modifiable risk of breast cancer in women. From a population of 128 women aged 25 to 75 years and over, a sample of 25 women was selected according to non-probabilistic sampling by criteria. It used descriptive statistics. In the study carried out, the age of 55 to 64 years prevailed, with a basic secondary school level. The results achieved show that women have risk factors for breast cancer, such as early menarche, alcohol consumption, smoking, and history of third-generation breast pathologies. The educational program consisted of four topics in six sessions and was evaluated as acceptable by specialist criteria. The educational program designed for the control of modifiable risk factors for breast cancer in women has an educational and transformative approach as it addresses the generalities of breast cancer, its risk factors, cancer prevention, and breast self-examination with projection group and systemic character.

Resumen
Over the years, crustaceans have colonized various ecosystems, including the rocky marine intertidal, thanks to their adaptive capacity; however, the lack of information and studies regarding this taxon makes it difficult to know its diversity and the state of its populations. Therefore, the objective was to evaluate the carcinofauna of four rocky beaches that have geomorphological differences in the provinces of Guayas and Santa Elena, Ecuador, including their relationship with physicochemical parameters of the water through an ecological analysis with sampling based on transects and quadrats. The results indicated that these parameters do not affect the distribution and presence of crustaceans, but rather, the structural shape of the beaches, indicating that the most heterogeneous beaches harbor a greater carcinological diversity due to the variety of evolutionary morphological adaptations that some have crustaceans.
