Published: December 2021

Introducción: El noroeste de Costa Rica representa un área con una alta riqueza geológica que evidencia rocas generadas en diferentes ambientes, como plano abisal, talud continental, plataforma continental, volcánicos continentales efusivos y explosivos, volcánicos submarinos, costeros, erosivos fluviales, erosivos gravitatorios, de intrusión y el manto terrestre.
Objetivo: Describir el contexto geológico actual del noroeste de Costa Rica, mediante el análisis y recopilación de datos de campo, geoquímicos, petrológicos, estructurales, paleontológicos y radiométricos con el fin de reconstruir los eventos y etapas de deformación desde el Jurásico a la actualidad.
Métodos: Se hizo una recopilación bibliográfica de estudios en diversas ramas geológicas para establecer un estado del arte del extremo noroeste de Costa Rica.
Resultados: La historia geológica representa el registro en rocas desde el Jurásico al Holoceno – actualidad con once etapas definidas a partir de interpretaciones petrológicas, estructurales, geocronológicas, estratigráficas y paleontológicas agrupadas en tres etapas de depositación y afectadas por cuatro fases tectónicas compresivas.
Conclusiones: Las etapas de depositación corresponden con una primera etapa magmática con afinidad oceánica entre el Jurásico y el Cretácico Superior, una segunda etapa predominantemente sedimentaria con un rango de edad entre el Cretácico Superior y el Oligoceno, y por último una etapa volcánica efusiva – explosiva ubicada desde el Plioceno hasta la actualidad. Las fases tectónicas se asocian con diferentes eventos entre placas. La primera se dio en el Cretácico Inferior y su principal resultado visible fue la emersión de la Ofiolita de Santa Elena; la segunda sucedió del Cretácico Superior temprano al Campaniano y su reconocimiento está ligado a la posición actual de la Ofiolita de Santa Elena y sus estructuras circundantes; la tercera fase aconteció desde el Eoceno Superior hasta el Mioceno y su principal producto fue la generación del tren de pliegues sedimentarios del Golfo de Santa Elena a bahía de Salinas; y por último se presenta una fase Cuaternaria que originó el eje de basculamiento de los productos piroclásticos frente a la cordillera volcánica de Guanacaste.
Spatial and temporal dynamics of the hydrology at Salinas Bay, Costa Rica, Eastern Tropical Pacific
Authors: Rodríguez Alejandro , Alfaro Eric-J. , Cortés Jorge 
Published: December 2021

Introduction: Salinas Bay is located in the warm pool of the Eastern Tropical Pacific (ETP), characterized by warm, shallow surface waters, a strong and shallow thermocline, and an important biological diversity. The primary productivity of the region is influenced by the coastal upwelling, which occurs during the boreal winter as a result of the strengthening of trade winds.
Objective: To study the spatial and temporal dynamics of physical and chemical parameters at seven hydrographic stations in Salinas Bay, Costa Rica, through the analysis of CTD data, and relate the warm and cold events to the regional atmospheric conditions present when measuring the data.
Methods: Seven hydrographic stations, sampled at Salinas Bay between August 2008 and December 2014, were selected. The variables processed for analysis are temperature, density, salinity, oxygen, chl-a and turbidity. Once the data was processed, 42 Hovmöller kind diagrams were plotted.
Results: All variables, except turbidity, presented a seasonal periodicity associated with the upwelling. In general, colder and denser waters, higher salinity and chl-a concentrations and lower dissolved oxygen values were observed during the dry season, when the upwelling was active. Whereas, during the rainy season water masses were warmer and less dense, salinity and chl-a concentrations decreased and dissolved oxygen values tended to increase.
Conclusions: The spatial and temporal dynamics of the hydrology in Salinas Bay was influenced by the coastal upwelling events. The region also presented an interannual variability associated with ENSO. Seasonal and interannual variability can counteract their effects on the oceanographic parameters when they coincide temporally.
Forcing of cool and warm subsurface water events in Bahía Salinas, Costa Rica
Authors: Alfaro Eric-J. , Cortés Jorge 
Published: December 2021

Introduction: Bahía Salinas, on the north Pacific coast of Costa Rica, is a seasonal upwelling area. Sea temperature in Bahía Salinas could be modulated by synoptic and other large-scale systems. This region belongs to the Central American Dry Corridor (CADC), a sub-region in the isthmus that is relatively drier than the rest of the territory, which extends along the Pacific littoral from western Guatemala through northern Costa Rica.
Objective: To study the warm and cold events that could be inferred by studying the sea subsurface temperature in Bahía Salinas, and also analyzing the large-scale conditions and synoptic systems of the historical sources when they occurred in order to identify the atmospheric mechanisms that favored their appearance.
Methods: A Sea Subsurface Temperature Index was calculated using hourly data from seven stations located at three different points in Bahía Salinas. Records range from June 19, 2003 to December 5, 2017. Additionally, six meteorological stations, with hourly wind records, were used to create two wind indices. The Sea Subsurface Temperature Index was used to identify the warmest and coldest events in the bay. Wind indices and monthly meteorological bulletins were used to analyze the large-scale conditions and synoptic systems in which cold and warm events occurred in Bahía Salinas.
Results: Mean sea temperature in Bahía Salinas is 25.2°C. Colder temperatures were observed in February-March, below 21°C. There were two maxima in May-June and August-October with temperatures above 27°C. In four of the five cold events studied, Northeasterly wind anomalies were observed in the Costa Rican North Pacific, associated with trade wind reinforcements; meanwhile westerly anomalies were observed in all the warm events, associated with weaker trade wind conditions.
Conclusions: The main seasonal climate driver in Bahía Salinas is the North Atlantic Subtropical High because its latitudinal migration is associated with the strength of the trade winds over Central America. Seasonal upwelling is modulated also by two synoptic scale climate features, the boreal winter arrival of cold front outbreaks and the winter maximum of the easterly Caribbean Low-Level Jet. El Niño-Southern Oscillation is also an important modulator of the sea temperature variability, since warm and cool events are related with positive and negative sea temperature anomalies.

Authors: González-Sánchez Kaylen , Flores-Alvarado Bryan , Montiel-Barrantes Paula , Gómez-Arce Gonzalo , Alvarado Juan-José 
Published: December 2021

Introduction: The class Ascidiacea has about 3 000 species, which fulfill various roles in the ecosystem, for example, they filter high amounts of particles, and are shelter and food for other animals. Furthermore, the group has a high number of invasive species reported. In Costa Rica, ascidians have been barely studied.
Objective: In this study, we aim to describe the diversity of ascidians in Costa Rica from new samplings in Área de Conservación Guanacaste, North Pacific, and by compiling previous reports for the entire country in order to improve the group’s state of knowledge.
Methods: Samples were collected during two field trips between 2018 and 2019, at six sites within the Gulf of Santa Elena and three sites near the Murcielago Islands area. The specimens were dissected and analyzed in detail to determine the species. All the identifications were compared with the available information from literature and from museum collections. Literature, collections databases of the National Museum of Natural History, Smithsonian Institution and the new material collected were used to create an updated taxonomic list.
Results: A total of eight species were obtained from 70 specimens. Of these, five are new reports for the country, which increase to 22 species the total number reported for Costa Rica. The most common species was Rhopalaea birkelandi, whose presence was higher in Santa Elena Bay.
Conclusions: This study improved the knowledge of ascidian diversity in Costa Rica. Polyandrocarpa anguinea, reported for the first time, is considered invasive in other areas, which suggests the necessity of a continuous monitoring of its population. It is necessary to include more areas of the country since almost all the reported species come from the North Pacific; the diversity of ascidians from other parts of the country, especially the Caribbean, is still unknown.
Postawy pokolenia Z wobec środowiska pracy na przykładzie pracujących studentów w Polsce i w Chorwacji – analiza porównawcza
Authors: Kawka Tomasz 
Published: December 2021

Objective: To interpret preliminary pilot studies diagnosing the attitudes of Generation Z towards work conditions in Poland and Croatia. It uses the example of a selected group of working students in the two countries. The level and attributes of professional satisfaction, the assessment of commitment, and selected components of the assessment of one’s work environment were the determinants of the individuals’ attitudes.Research Design & Methods: Comparative research was carried out using a modified P.A.S.Z. questionnaire. The first section characterises the group of Generation Z employees, who were beginning to work. The next section examines the results of the research and discusses the similarities and differences in the expectations young Poles and Croats have of work towards the work. The group surveyed was made up of individuals finishing their university education and beginning their first stage of development and gaining professional experience. Against this background, fundamental questions and research hypotheses were verified. This constitutes the basis for the further stages of comparative research on the subject.Findings: The research shows that working students appreciate their work environment as one characterised by a high level of professional satisfaction. Working students in Poland and Croatia show an identical structure of values and motives for taking up work, both leading to job satisfaction.Implications / Recommendations: Despite their cultural differences and different nationalities, the Polish and Croatian representatives of Generation Z had very similar results in terms of their expectations and attitudes. Thus, an assumption can be made about a global, homogeneous perception of one’s professional role by the youngest generation entering the labour market in the sample of students.Contribution: The study confirms the characteristics of Generation Z as a homogeneous and global generation in terms of how they perceive their work environment.

Published: December 2021

A estabilização é uma técnica para melhoria das propriedades do solo, entretanto, poucos estudos apresentam uma metodologia de dosagem para a adição de ligantes como visto para concretos. A presente pesquisa busca analisar o efeito do índice porosidade/teor volumétrico de ligante no comportamento de um solo argiloso. Os fatores controláveis são as quantidades de cinza volante e de cal dolomítica e o peso específico aparente seco. Os resultados indicam aumento da resistência a compressão não confinada com a adição de cal e cinza, assim como com a redução da porosidade. Além disso, foi possível comprovar a eficácia do índice porosidade/teor volumétrico de ligante na análise do comportamento de solos argilosos.

Published: December 2021

Polycystic ovary syndrome (PCOS), a multifaceted condition, often has salient features like insulin resistance (IR). Abnormal alternation in insulin synthesis and function usually alters PCOS expressivity by deviating molecular and biochemical activity underlying this pathophysiology.This review intends to unveil the molecular basis of the genetic polymorphism of IR and its correlation with PCOS. It also highlights the existing methods of IR estimation.Searching of different articles using keywords including PCOS, IR, and polymorphism in various databases was performed to illustrate the review article.POCS, and IR are complex and multifactorial conditions in terms of the contributing factors, their interactions, and expressivity. Further studies on diversified genotype responses to environmental and ethnic variances are required for precise understanding.Insulin resistance (IR) and polycystic ovary syndrome (PCOS) are intricately interacted conditions that abnormally alter functions from genetic to organ system level. Complex gene-environment interactions make it difficult to understand the etiology and manifestation, and so diagnosis and management approaches of the heterogeneous pathophysiology are not foolproof. Further studies on genetic susceptibility related to ethnic distribution are essential for the implementation of personalized treatment of IR and PCOS.
Prevalence of ADHD in children born by mothers consuming Frankincense during pregnancy
Authors: Ranjbar Alimohammad , Kamali Ardakani Elahe , Zareshahi Rahele 
Published: December 2021

Aims: In Iranian culture, due to some narratives from the prophet Mohammad about the use of frankincense during pregnancy for increasing IQ in children, some women consume frankincense during expectancy. This study's goal is to evaluate the relationship between frankincense used during pregnancy and the incidence of ADHD.
Methods: In this study, the case group comprised children 4-17 years old referring to Shahid Chamran Pharmacy in Yazd from summer to winter 2018 for receiving Methylphenidate, those with whom a psychologist had identified ADHD based on DSM-V factors. The control group included children of the same age group but without ADHD. For data gathering, a checklist was used with some questions on smoking, family history of ADHD, presence/absence of a specific disease during pregnancy, frankincense used during pregnancy, and a chemical medication consumed during pregnancy.
Results: The main result demonstrated that the children whose mothers used frankincense during pregnancy were 0.67 times less likely to be affected by ADHD than those whose mothers did not use this substance. However, the difference failed to be statistically significant (P>0.05).
Conclusion: Some studies report that frankincense can bear a positive effect on the development of the brain and possibly adequate formation of dendrites trees, axons and induce proper communication between them, so the impact of frankincense on the brain may be justified by its protective effect against the hyperactive child.

Authors: Tayyebi Ghasem 
Published: December 2021

In order to learn vocabulary efficiently, the utilisation of learning strategies is very important and surely it depends on learners’ attempts. The current study aimed at examining the strategies that Iranian elementary English as a foreign language (EFL) learners adopt for learning English vocabulary. To this end, based on the performance of the participants on the Quick Placement Test, the researcher recruited 100 participants through availability sampling. To determine the strategies that the participants employ for learning English vocabulary, Schmitt’s taxonomy of vocabulary learning strategies (VLSs) questionnaire was administered. The findings of the current study indicated that Iranian elementary EFL students were medium VLS users. The social strategy was found as the most frequently used category of strategies, followed by memory, determination, cognitive and metacognitive strategy.

Authors: Trianto Budi , Masrizal Masrizal 
Published: December 2021

Indonesia continues to strive to develop Islamic finance especially its Islamic banking and sukuk to support the real sector. The growth of Islamic finance in Indonesia is expected to encourage the development of the national economy. This study aims to investigate the impact of Islamic banking financing and sukuk financing on Indonesia’s industrial output. Applying the Autoregressive Distributed Lags (ARDL) framework to monthly data from January 2011 to December 2018, we find Islamic bank financing to contribute positively to the real sector in both the long and short term. In addition, we also document positive long run contribution of sukuk financing to industrial output . Indeed, over the long run, sukuk financing tends to have a greater real impact than Islamic banking financing. The results of the study implies that Islamic banking and sukuk play a vital role in supporting the real sector in Indonesia. Accordingly, recent initiatives by Indonesia to further develop its Islamic finance are steps in the right direction.
