En Costa Rica existen muy pocas investigaciones en el área de la enseñanza de la genética en secundaria, a pesar de la importancia que tiene esta disciplina actualmente, siendo base fundamental para otras áreas de las ciencias como las de la salud, las agrarias o ambientales. El propósito de este trabajo es analizar las técnicas utilizadas por dos profesoras para desarrollar los temas de genética mendeliana e identificar los diferentes estilos de aprendizaje que poseen los estudiantes de décimo año de dos colegios diurnos de Costa Rica. La investigación se desarrolló en un enfoque mixto, utilizando tres tipos de instrumentos. Entre los resultados más destacables se observó poco conocimiento del tema de estilos de aprendizaje por parte de las docentes; las clases que se desarrollan son del tipo magistral, además, los temas con mayor y menor dificultad en los tópicos de genética mendeliana no concuerdan entre profesoras y estudiantes. Existe diversidad de estilos de aprendizaje en los estudiantes, siendo el auditivo el de mayor predominancia a nivel general. Así mismo, se identificaron estudiantes que pueden desarrollar una alta o baja predominancia simultáneamente en los tres estilos de aprendizaje (visual, auditivo, kinestésico), indicando que por lo general las personas durante su proceso de aprendizaje presentan varios estilos, cuya predominancia es posiblemente multifactorial.ABSTRACTThe Bandler-Grinder Learning Model and teaching techniques forMendelian genetics in Costa Rican tenth grade students. Educationin genetics is basic for learning in other areas such as health, agricultureand environmental sciences. In Costa Rica, little is known about geneticseducation in high school, despite the importance of this disciplineto society. Here we analyze the techniques used in two Costa Ricaninstitutions to teach Mendelian genetics, and identify the learningstyles based on the NLP Bandler & Grinder Learning Model. The researchwas conducted under a mixed approach in ten-grade students fromtwo daytime high schools. We used three kinds of instruments: semi-structured interview, observation by recording critical incidents inclass and a learning styles test. We found that the teachers had littleknowledge of learning styles, and that lessons are developed mainlyas master classes. Teachers and students do not agree on the degree ofdifficulty of several subtopics of Mendelian genetics. Even though theauditory style was predominat, we found that the prevalence is probablymultifactorial.

Jennifer M. Piscopo examines how the crisis of representation in Costa Rica has placed a ceiling on gender equality in representation. The restructuring of the Costa Rican party system and party fragmentation has made electing multiple candidates from any one ballot more difficult. Top spots have become even more prestigious and more likely to be allocated to men, which reduces women’s electoral chances. Corruption scandals, party breakdown, citizen frustration, and economic problems tainted the administration of the nation’s first female president, Laura Chinchilla. Female legislators have often worked to promote women’s issues and feminist policies, but Chinchilla eschewed feminism, even though several of her policies did benefit women. Overall, her failed presidency may create difficulties for other women seeking top political offices and could have negative consequences for views of women in politics. These challenges notwithstanding, Piscopo concludes that Costa Rica remains at the vanguard of women’s political representation in Latin America.

From a critical and transformative approach, this essay presents inputs and relevant conclusions obtained during the first stage of the project Construyendo una propuesta de implementación del Programa Maestros Comunitarios (PMC), Code number 0166-15 DEB-UNA (UNA, DEB, s. f.), conducted in 2016. Considering our perspective as researchers and professors at División de Educación Básica, the paper addresses a current topic within the socio-educative field to face challenges of contemporary educational models in formal and non-formal areas of elementary education in the Costa Rican context. Our purpose is that students and teachers of the career program Pedagogía con énfasis en I y II ciclos de la Educación General Básica have an overview of the national, social, and educational reality in an attempt to involve them in applying pedagogical actions towards finding a solution to school dropouts at Escuela Finca Guararí, Heredia, Costa Rica. The essay describes the experience of teaching education students and their socio-educational action with the focus on the systematization of the experience in the initial stage of the project. Furthermore, the paper connects with emerging strategic knowledge areas at División de Educación Básica (DEB), such as social and community pedagogy in the context of the National University (UNA) of Costa Rica. It takes over a route already traced at DEB, which proposes more flexible and alternative pedagogic formats to promote educational equity and diversity issues. The paper describes the project background and a theoretical framework, as well as aspects that have been shared by the protagonist actors along the process: students-teachers, host teachers, supervisor professors, school children, and their parents at Escuela Finca Guararí. Conclusions address main results and facts during 2016 in order to show the viability of the project, which is conducted from a public university. Finally, the article also includes an overview of the project’s future in terms of its implementation in the Costa Rican context.

The years following World War Two produced a strong resurgence of U.S. intervention in Central America and the Caribbean couched in Cold War terms. Although the U.S. intervention in Guatemala to overthrow the government of Jacobo Arbenz in 1954 has generally been seen as the first case of Cold War covert anti-Communist intervention in Latin America, several scholars have raised questions about U.S. involvement in a 1948 Costa Rican civil war in which Communism played a critical role. In a 1993 article in The Americas, Kyle Longley argued that “the U.S. response to the Costa Rican Revolution of 1948, not the Guatemalan affair, marked the origins of the Cold War in Latin America.” The U.S. “actively interfered,” and achieved “comparable results in Costa Rica as in Guatemala: the removal of a perceived Communist threat.” Other authors have argued, even, that the U.S. had prepared an invasion force in the Panama Canal Zone to pacify the country. The fifty years of Cold War anti-Communism entitles one to be skeptical of U.S. non-intervention in a Central American conflict involving Communism. Costa Ricans, aware of a long tradition of U.S. intervention in the region, also assumed that the U.S. would intervene. Most, if not all, were expecting intervention and one key government figure described U.S. pressure as like “the air, which is felt, even if it cannot be seen.” Yet, historians must do more than just “feel” intervention. Subsequent Cold War intervention may make it difficult to appraise the 1948 events in Costa Rica objectively. Statements like Longley's that “it is hard to believe that in early 1948 … Washington would not favor policies that ensured the removal of the [Communist Party] Vanguard,” although logical, do not coincide with the facts of the U.S. role in the conflict.

This study aims to obtain a concrete picture of the effectiveness of the application of the principles of teacher Islamic communication in fostering the character of tenth grade students of Madrasah Aliyah Negeri Rantauprapat. The communication process in education is not only understood as a one-way knowledge transfer process, however, there must be a serious effort on the part of the educator / teacher, as a communicator, to be able to provide good role models. Qualitative research methods try to understand a phenomenon as the understanding of the respondents studied, with an emphasis on the subjective aspects of one's behavior. Qualitative research provides an opportunity for researchers to understand the way respondents describe the world around them based on the way they think. The researcher tries to enter the conceptual world of the subject under study to capture what and how things happen. Data collection techniques used in this study were interviews in this study researchers used a semi-structured interview (semitructure interview), namely: interviews in the category of in-depth interviews. Data about the application of teacher Islamic communication and the communication character of tenth grade students, data analysis used in this study during the field using the Miles and Huberman Model, namely the activities in qualitative data analysis are carried out interactively and continue continuously until completion, so that the data is already saturated.

BACKGROUND The Costa Rican vaccination program uses Pfizer-BioNTech and Oxford-AstraZeneca vaccines. Real-world estimates of these vaccines effectiveness to prevent hospitalizations range from 90% to 98% for two doses and from 70% to 91% for a single dose. Almost all of these estimates predate the Delta variant. OBJECTIVE To estimate the dose-dependent effectiveness of coronavirus disease (COVID-19) vaccines to prevent severe illness in real-world conditions of Costa Rica, after the Delta variant became dominant. METHODS This observational study is a secondary analysis of hospitalizations prevalence. The participants are all 3.67 million adults residents in Costa Rica by mid-2021. The study is based on public aggregated data of 5978 COVID-19-related hospital records from 14th September to 20th October, 2021 and 6.1 million vaccination doses administered to determine hospitalization prevalence by dose-specific vaccination status. The intervention retrospectively evaluated is vaccination with Pfizer-BioNTech (78%) and Oxford-AstraZeneca (22%). The main outcome studied is being hospitalized. RESULTS Vaccine effectiveness to prevent hospitalization (VEH) was estimated as 93.4% (95% confidence interval [CI]: 93.0 to 93.9) for complete vaccination and 76.7% (CI: 75.0 to 78.3) for single-dose vaccination among adults of all ages. VEH was lower and more uncertain among older adults aged 58 years and above: 92% (CI: 91% to 93%) for those who had received full vaccination and 64% (CI: 58% to 69%) for those who had received partial vaccination. Single-dose VEH declined over time during the study period, especially in the older age group. Estimates were sensitive to possible errors in the population count used to determine the residual number of unvaccinated people when vaccine coverage is high. CONCLUSIONS The Costa Rican vaccination program that administered Pfizer and Oxford vaccines are highly effective to prevent COVID-19-related hospitalizations after the Delta variant had become dominant. Moreover, a single dose is reasonably effective, justifying the continuation of the national policy of postponing the application for the second dose of the Pfizer vaccine to accelerate the vaccination and increase the number of people being vaccinated. Timely monitoring of vaccine effectiveness is important to detect eventual failures and motivate the public based on information that the vaccinations are effective.

AbstractOmiodes Guenée is redescribed based on all New World species, including the type species O. humeralis Guenée. Four new species from Costa Rica, O. janzeni sp. n., O. hallwachsae sp. n., O. sirena sp. n., O. ochracea sp. n., are described. Ten new synonymies are established : Phostria disciiridescens Hampson is =O. croeceiceps (Walker), Phostria cayennalis Schaus is =O. grandis (Druce), Omiodes ochrosoma Felder & Rogenhofer and Phryganodes gazalis Schaus are =O. pandaralis (Walker), Nacoleia lenticurvalis Hampson, Phryganodes anchoritalis Dyar, and Phostria duplicata Kaye are =O. confusalis (Dognin), O. cervinalis Amsel is =O. martvralis (Lederer), Nacoleia indicata ab. pigralis Dognin and Botis fortificalis Möschler are =O. metricalis (Möschler). One new combination is recognized: O. pandaralis (Walker) was transferred from Coelorhynchidia Hampson. A key and an updated checklist to the neotropical Omiodes species is provided, including O. indicata (Fabricius), a worldwide pest. Ten species that do not belong in Omiodes are retained until appropriate generic placements are identified.
