Elastic prestack seismic inversion through discrete cosine transform reparameterization and convolutional neural networks
Authors: Aleardi Mattia , Salusti Alessandro
Published: October 2020

We have developed a prestack inversion algorithm that combines a discrete cosine transform (DCT) reparameterization of data and model spaces with a convolutional neural network (CNN). The CNN is trained to predict the mapping between the discrete cosine-transformed seismic data and the discrete cosine-transformed 2D elastic model. A convolutional forward modeling based on the full Zoeppritz equations constitutes the link between the elastic properties and the seismic data. The direct sequential cosimulation algorithm with joint probability distribution is used to generate the training and validation data sets under the assumption of a stationary nonparametric prior and a Gaussian variogram model for the elastic properties. The DCT is an orthogonal transformation that we used as an additional feature extraction technique that reduces the number of unknown parameters in the inversion and the dimensionality of the input and output of the network. The DCT reparameterization also acts as a regularization operator in the model space and allows for the preservation of the lateral and vertical continuity of the elastic properties in the recovered solution. We also implement a Monte Carlo simulation strategy that propagates onto the estimated elastic model the uncertainties related to noise contamination and network approximation. We focus on synthetic inversions on a realistic subsurface model that mimics a real gas-saturated reservoir hosted in a turbiditic sequence. We compare the outcomes of the implemented algorithm with those provided by a popular linear inversion approach, and we also evaluate the robustness of the CNN inversion to errors in the estimated source wavelet and to erroneous assumptions about the noise statistic. Our tests confirm the applicability of our proposed approach, opening the possibility of estimating the subsurface elastic parameters and the associated uncertainties in near real time while satisfactorily preserving the assumed spatial variability and the statistical properties of the elastic parameters.
Controlled administration of cannabis to mitigate cannabis-attributable harm among recreational users: a quasi-experimental study in Germany
Authors: Manthey Jakob , Kalke Jens , Rehm Jürgen , Rosenkranz Moritz , Verthein Uwe
Published: October 2020

Background:New approaches are required to slow down or reverse increasing trends of levels of delta-9-tetrahydrocannabinol (THC) and cannabis-attributable hospitalizations in Germany. Legal access to cannabis may constitute one viable effective policy response; however, available evidence does not suffice to inform a regulation model for Germany. The proposed study aims to reduce harm for cannabis users through legal access to herbal cannabis through pharmacies.

Protocol:A quasi-experimental study comparing cannabis users with legal access to herbal cannabis (Berlin, intervention group) to those without legal access (Hamburg, control group) (total N=698). As the primary outcome, we hypothesize that: 1) illegal THC consumption will reduce by at least 50% in the intervention group and 2) total THC exposure in the intervention group will be reduced by at least 10% lower than that of the control group, taking into account baseline values. Secondary outcomes comprise measures of frequency of use, THC-impaired driving, and mode of administration. Paired t-tests and multilevel regression models will be performed for statistical analyses.

Discussion:This study proposal is currently being reviewed by the ‘Federal Institute for Drugs and Medical Devices’ – the body responsible for approving research studies on classified substances, including cannabis. Upon approval and prior to the start of the study, a full ethical review will be undertaken. Results may inform a regulation model for Germany and other jurisdictions and are expected to deepen the understanding of the effects of legal access to cannabis.

Thank Martin Luther that ciprofloxacin could cure your gonorrhoea? Ecological association between Protestantism and antimicrobial consumption in 30 European countries
Authors: Kenyon Chris , Fatti Geoffrey
Published: October 2020

Background:Higher consumption of antimicrobials plays an important role in driving the higher prevalence of antimicrobial resistance in Southern compared to Northern Europe. Poor controls on corruption (CoC), high uncertainty avoidance (UA) and performance vs. cooperation orientation (POCO) of societies have been found to explain much of this higher consumption in Southern European countries.  We hypothesized that these predictors were in turn influenced by the Protestant Reformation in the 16thcentury onwards.

Methods:We used structural equation modelling (SEM) to assess the relationships between country-level proportions being Protestant, CoC, UA, POCO and four markers of antimicrobial consumption in the community (all antibacterials, cephalosporin, macrolides and fluoroquinolones).

Results:The proportion of a country that was Protestant was negatively correlated with the consumption of all antibacterials. SEM revealed that UA predicted all antibacterial consumption (direct effect coef. 0.15, 95% Confidence Interval [CI] 0.04-0.26). The proportion Protestant exerted an indirect effect on consumption (coef. -0.13, 95% CI -0.21- -0.05). This effect was mediated predominantly via its effect on UA (direct effect coef. 0.15, 95% CI 0.04-0.26). The model explained 37% of the variation in consumption.  Similar results were obtained for each of the other three classes of antimicrobials investigated.

Conclusions:Our results are compatible with the theory that contemporary differences in antimicrobial consumption in Europe stem in part from cultural differences that emerged in the Reformation. These findings may explain the differential efficacy of similar antibiotic stewardship campaigns in Northern and Southern European populations.

A partir disso, apresenta-se como livros-textos tradicionais de administração reproduzem essa mitologia, dificultando a construção de uma linguagem crítica em administração.
Program assessment in innovation ecosystems
Authors: Stein da Silva Luiza , Gaia Hoffmann Micheline
Published: October 2020

The objective of this study is to analyze how different typologies and evaluation approaches relate to assessment requirements of a program inserted in an innovation ecosystem. Methodology involved interviews with 21 stakeholders and a documentary survey. Although the nature of the program suggests greater alignment with developmental evaluation and a subjectivist approach, the results also imply assessment demands based on the objectivist approach. Conclusions highlight the relevance of stakeholders’ demand for defining evaluation guidelines, and indicate that programs inserted in collaborative networks receive a diversity of demands that require multiple typologies and approaches.
Politics and business on the Russian background (O.Z. Mushtuk's textbook «Business and politics»)
Authors: Matyuhin A.
Published: October 2020

The purpose of this review is to present and analyze the original textbook of the candidate of historical Sciences, Professor O.Z. Mushtuk "Business and politics", which has no analogues in the Russian educational literature. The author is known for many years of research on complex problems of the relationship between the political and business spheres of modern Russian realities. O.Z. Mushtuk broke his rich experience and knowledge through the creation of this manual, which also has an applied nature of a kind of practical course in political science for entrepreneurs. This is a serious attempt to answer basic questions – not only "who is to blame" for the troubles of modern Russian business, but also" what should domestic entrepreneurs do " in their relations with the state, bureaucratic structures, political parties, public organizations, and local authorities. According to the author, it is important for domestic business to solve two key tasks: on the one hand, to obtain from the state, officials the right to constructive dialogue and responsible business partnership, and on the other hand, to change the negative image formed by years of Russian market reforms, the negative image in the eyes of the population. To do this, the business community needs to become a truly creative, creative class, aware of its responsibility, aware of its social mission to serve the entire society, not just its own pocket and individual Bank accounts.
Private Information and Dynamic Bargaining in Supply Chains: An Experimental Study
Authors: Davis Andrew M. , Hyndman Kyle
Published: October 2020

Problem definition: We conduct a controlled human-subjects experiment in a two-tier supply chain where a supplier’s per-unit production cost may be private information while bargaining with a buyer. Academic/practical relevance: Academically, supply chain studies often assume full-information or highly structured bargaining. We consider private information with dynamic, unstructured bargaining. In practice, a buyer may not know its supplier’s cost exactly and interact with its supplier in a back-and-forth bargaining environment. Thus, understanding how a supplier’s private cost information affects both supply chain outcomes and bargaining is new to the literature and relevant to practice. Methodology: We employ insights from mechanism design to generate restrictions on the space of agreements and solve for a specific bargaining solution under private information to generate precise predictions. These predictions are then tested through a human-subjects experiment. Results: In our experiment, theory predicts that all supplier types should earn at least 50% of total profits when their cost information is private. However, we find that high-cost suppliers earn a disproportionately low share of total profits under private information, 20.16%. We show that this is because buyers, under private information, act as if they are bargaining with the lowest-cost supplier and suppliers do not appear to blame buyers for behaving this way. Based on these findings, we conduct an additional experiment where suppliers have the ability to communicate their private costs to buyers and observe that verifiable disclosure significantly increases profits for high-cost suppliers. Managerial implications: High-cost suppliers actually suffer from having their costs as private information, which runs counter to theory. However, if high-cost suppliers can credibly disclose their costs to buyers, they can significantly increase profits. Lastly, although private information does not lead to more disagreements, negotiations do take longer, which can be costly to firms.

Os artífices do poder: mecanismos de ascensão social em Guarapiranga (MG), 1715-1820
Authors: Alves Débora Cristina
Published: October 2020

O presente trabalho tem como intuito analisar as mudanças conjunturais, políticas, sociais e econômicas, no século XVIII e início XIX (1715 a 1820), experimentadas por indivíduos que se dedicaram ao comércio, nas Minas Gerais. Por intermédio de inventários post-mortem, processos matrimoniais, cartas patentes do Arquivo Histórico Ultramarino e documentos do Arquivo da Torre do Tombo, a pesquisa analisa alguns sujeitos da freguesia que instituíram redes de negócios, alianças familiares e demais estratégias para ascenderem socialmente e adquirirem poder e distinção. Para tanto, observamos a riqueza material que conquistaram e o poder imaterial, como benesses, privilégios, comendas, mercês, ofícios que obtiveram ao longo de suas trajetórias com o propósito de participarem do rol dos grandes e importantes senhores na região. Observamos que esses indivíduos e suas famílias mantiveram no início do oitocentos os mesmos mecanismos empregados ao longo do setecentos, como alianças, obtenção de concessões, mercês, privilégios e aquisição de riquezas para se conservarem entre a camada mais abastada da população. Embora regidos por um sistema político que procurava se diferenciar e de ideais liberais, os habitantes de Minas no início do XIX, perpetuaram os mesmos padrões de hierarquização, exclusão e domínio do século XVIII.
Asynchronous Assistance: A Social Network Analysis of Influencing Peer Interactions in PeerWise
Authors: Shields Tomas , Gray Geraldine , Ryan Barry J.
Published: October 2020

This mixed methods, investigative case study explored student patterns of use within the online PeerWise platform to identify the most influencing activities and to build a model capable of predicting performance based on these influencing activities. Peerwise is designed to facilitate student peer-to-peer engagement through creating, answering and ranking multiple choice questions; this study sought to understand the relationship between student engagement in Peerwise and learning performance. To address the research question, various usage metrics were explored, visualized and modelled, using social network analysis with Gephi, Tableau and Python. These findings were subsequently analyzed in light of the qualitative survey data gathered. The most significant activity metrics were evaluated leading to rich data visualisations and identified the activities that influenced academic performance in this study. The alignment of the key qualitative and quantitative findings converged on answering questions as having the greatest positive impact on learner performance. Furthermore, from a quantitative perspective the Average Comment Length and Average Explanation Length correlated positively with superior academic performance. Qualitatively, the motivating nature of PeerWise community also engaged learners. The key limitation of the size of the data set within the investigative case study suggests further research, with additional student cohorts as part of an action research paradigm, to broaden these findings.

Volumetric Lissajous confocal microscopy with tunable spatiotemporal resolution
Authors: Deguchi Takahiro , Bianchini Paolo , Palazzolo Gemma , Oneto Michele , Diaspro Alberto , Duocastella Martí
Published: October 2020

Dynamic biological systems present challenges to existing three-dimensional (3D) optical microscopes because of their continuous temporal and spatial changes. Most techniques are rigid in adapting the acquisition parameters over time, as in confocal microscopy, where a laser beam is sequentially scanned at a predefined spatial sampling rate and pixel dwell time. Such lack of tunability forces a user to provide scan parameters, which may not be optimal, based on the best assumption before an acquisition starts. Here, we developed volumetric Lissajous confocal microscopy to achieve unsurpassed 3D scanning speed with a tunable sampling rate. The system combines an acoustic liquid lens for continuous axial focus translation with a resonant scanning mirror. Accordingly, the excitation beam follows a dynamic Lissajous trajectory enabling sub-millisecond acquisitions of image series containing 3D information at a sub-Nyquist sampling rate. By temporal accumulation and/or advanced interpolation algorithms, the volumetric imaging rate is selectable using a post-processing step at the desired spatiotemporal resolution for events of interest. We demonstrate multicolor and calcium imaging over volumes of tens of cubic microns with 3D acquisition speeds of 30 Hz and frame rates up to 5 kHz.

Published: October 2020

Excitation of dye-loaded perfluorocarbon nanoparticles (nanobombs) can generate highly localized axially propagating longitudinal shear waves (LSW) that can be used to quantify tissue mechanical properties without transversal scanning of the imaging beam. In this study, we used repetitive excitations of dodecafluoropentane (C5) and tetradecafluorohexane (C6) nanobombs by a nanosecond-pulsed laser to produce multiple LSWs from a single spot in a phantom. A 1.5 MHz Fourier-domain mode-locked laser in combination with a phase correction algorithm was used to perform elastography. Multiple nanobomb activations were also monitored by detecting photoacoustic signals. Our results demonstrate that C6 nanobombs can be used for repetitive generation of LSW from a single spot for the purpose of material elasticity assessment. This study opens new avenues for continuous quantification of tissue mechanical properties using single delivery of the nanoparticles.

Published: October 2020

A tanulmány célja, hogy összevessük a szállodák weblapjain és vendégértékeléseiben megjelenő CSR4 tartalmakat. Kutatási eredményeink körvonalazzák a szállodák CSR tevékenysége és a valós fogyasztói tapasztalatok közötti különbséget, vagyis az úgynevezett value-action gap-et (VAG). A vizsgálatot a TripAdvisor listája szerinti párizsi top 10 zöld szálloda körében végeztük. Tartalomelemzéssel értékeltük a szállodák weblapjain elérhető CSR információkat, valamint megvizsgáltunk a TripAdvisoron összesen 8974 db szállodai vendégvéleményt, melyből 156 db vendégértékelés volt CSR tevékenységet minősítő visszajelzés. A kutatás eredménye rámutatott arra, hogy a szállodák eltérő részletességgel tájékoztatják honlapjaikon a vendégeket a CSR tevékenységeikről. A kommentek túlnyomórészt pozitív véleményt alkottak az egyes CSR kategóriákban, azonban nem minden témakör jelent meg. A kutatás eredményei nagymértékben hozzájárulhatnak a hotelek CSR stratégiájának kiépítéséhez.

Published: October 2020

A tanulmány a turizmus és a tárgy kapcsolatával foglalkozik, amelyben nem a turizmus és a tárgy viszonyának alapvető kérdéseit boncolgatjuk, hanem azt mutatjuk meg, hogyan lehet egy innovatív tárgyat megalkotni három különböző tudományág közös jellemzőinek megtalálásán, erősségeinek ötvözésén és végül egy tervezői koncepció felállításán keresztül. A B-bridge koncepció lényege egy olyan eszköz megteremtése, amely aktív és inaktív módon is segíti a Budapestre érkező turisták élményszerzését. Aktív állapotban a tárgy hozzájárul a turista aktív és passzív időeltöltéséhez, míg a hazatérés után inaktívan, emléktárgyként szolgál az utazási élmények elraktározására, később pedig felidézésére. Munkánk nem lenne teljes a tárgy gazdasági hasznosságának ismertetése nélkül, hiszen mai világunkban elengedhetetlen, hogy egy jó ötlet pénzügyileg is releváns megalapozottsággal rendelkezzen. Kutatásunk záróakkordjaként bemutatjuk a javasolt tárgy megalkotásában rejlő kihívásokat és a jövőbeli lehetőségeket.

Moved to Tears: Erwin Koch and Emotional Engagement in Literary Journalism
Authors: McQueen Kate
Published: October 2020

Journalism research broadly has begun to acknowledge a fact long accepted in the field of literary journalism: that emotional engagement can be an advantageous trait of a reported story. But there is still much to learn about how journalistic texts facilitate emotional involvement in readers. This article adds to this body of knowledge in two ways. It explores the history and theory of emotional appeals in literary journalism, and it offers an analysis of the stylistic strategies of emotive Swiss literary journalist Erwin Koch. Koch succeeds in eliciting both strong emotion and critical acclaim by using a condensed yet distanced narrative style, which is particularly effective at mirroring his subjects’ experience of being in the world. Through analysis of Koch’s work and its reception, this article offers insight into the nature of immersive reading experiences and points to opportunities for future research on the topic of affect in literary journalism.

Authors: Haza Julia , Wagner Alexis
Published: October 2020

This paper investigates the adpositional marking and case marking systems in Lutuv. This investigation finds that the basic adpositional phrase consists of a noun and a simplex or complex postposition. Complex postpositions are often used to convey information about both movement and location, whereas simplex postpositions are usually limited to expressing one of the two. The findings of this investigation are useful for highlighting potential future areas of research in Lutuv.
Expansion and inflammation of white adipose tissue - focusing on adipocyte progenitors
Authors: Liu Wenjing , Li Dahui , Cao Handi , Li Haoyun , Wang Yu
Published: October 2020

Adipose tissue is an important organ in our body, participating not only in energy metabolism but also immune regulation. It is broadly classified as white (WAT) and brown (BAT) adipose tissues. WAT is highly heterogeneous, composed of adipocytes, various immune, progenitor and stem cells, as well as the stromal vascular populations. The expansion and inflammation of WAT are hallmarks of obesity and play a causal role in the development of metabolic and cardiovascular diseases. The primary event triggering the inflammatory expansion of WAT remains unclear. The present review focuses on the role of adipocyte progenitors (APS), which give rise to specialized adipocytes, in obesity-associated WAT expansion, inflammation and fibrosis.
Tact or frankness in English and Russian blind peer reviews
Authors: Larina Tatiana , Ponton Douglas Mark
Published: October 2020

In a context of increasing globalization of academic discourse, considerations of the impact of culture on different communicative genres and discursive practices become more relevant than ever, as the construction of pragmatic meaning and its appropriate interpretation by the recipient is seen to depend on lexico-grammatical features whose use is greatly affected by cultural factors. This paper concerns the genre of blind peer review, and examines how disagreement and negative evaluation are expressed in two cultural and linguistic settings, and to what extent they are mitigated. It is based on peer reviews submitted, in English and Russian, to the Russian Journal of Linguistics, in which the reviewer provides a negative evaluation (either “reject” or “to be resubmitted after substantial revisions”). Such reviews entail possible face damage, in the terms of (Brown and Levinson 1978); and therefore one might expect reviewers to engage in discursive strategies of mitigation. The paper analyses 120 authentic blind reviews (70 Russian and 50 British English), using a pragmatic, contextual and contrastive methodology. Drawing on discourse analysis, intercultural pragmatics, (im)politeness theory and cultural studies, we explore the construction of alternative meanings in reviewers’ messages, and theorise that consideration for the face requirements of the reviewee and politeness strategies, may account not only for individual but also culture-specific choices. The results show that, as well as variations in reviewers’ individual styles, there are some culture-specific traits in this area. Mitigation strategies are more typical of English communication than Russian. We account for these differences in terms of the sociocultural context, value differences and the use of different mechanisms of politeness. Our results suggest that politeness is based on different communicative styles and expressive traditions, which appear to vary across cultures.
Innovative Empirical Model for Predicting National Banks’ Financial Failure with Artificial Intelligence Subset Data Analysis in the United States
Authors: Kasztelnik Karina
Published: October 2020

The principal objective of this research study was to investigate the impact of the Great Economic Recession of 2008 on national banks’ equity investment valuations and create an empirical model for predicting national banks’ financial failure in the United States. The focal period of the study was from 2009 to 2012, and public data sources used. It is not known to what extent national banks’ stock value investments are based on the return on equity. This causal-comparative study explores the degree to which national banks’ value investment in terms of the price to earnings ratio impacts their return on equity and the extent to which these banks’ stock value investment in terms of dividend yield impacts their return on equity. We used statistical modeling and the machine learning model to find hidden patterns in the input data. The principal finding of this research is that the median earnings per share in 2012 and the dividend yield in 2009 were significantly larger than the median return on equity in 2009 and 2012. Additionally, the dividend yield in 2012 was significantly smaller than the median return on equity in 2012. These findings can contribute to improving our understanding of how banks can predict financial failure using the new machine learning features of artificial intelligence to build an early warning system with the innovative risk measurement tool.
Israël, Jésus et les apôtres : summa memoriae christiana
Authors: Butticaz Simon
Published: October 2020

This article aims at describing the Lukan project by applying – in the wake of other scholars – social memory theories to Luke’s double work. In particular, it argues that the type of memory and its criteria defined by Jan Assmann on the basis of the Deuteronomy can help explain the nature of the narrative composed by the auctor ad Theophilum as well as its originality in an early Christian context marked by a proliferation of books and other traditions of the origins of the Church (cf. Luke 1:1a.2.4).
A Naked Seed: Platonism, Stoicism, or Agriculture in 1Cor 15,37?
Authors: Cook John Granger
Published: October 2020

Paul’s expression in 1Cor 15,37, γυμνὸς κόκκος, has nothing whatsoever to do with a Platonist naked soul or Stoic imagery of sowing and seeds. The context itself indicates that an immortal Platonic soul is not the reference of γυμνὸς κόκκος. The Platonist texts and the Stoic imagery of sowing and seeds do not resemble Paul’s affirmations in 1Cor 15,37. Instead, texts from Greek biology and agriculture are far more illuminating. The naked seed of 1Cor 15,37 are a metaphor for sown dead bodies. The context and comparative texts indicate Paul’s fundamental analogy: the naked seed is to the sown body as the plant body is to the body that will be.

BACKGROUND AND OBJECTIVES:

Attention-deficit/hyperactivity disorder (ADHD) cohort studies have typically involved clinical samples and have usually recruited children across wide age ranges, limiting generalizability across complexity and developmental stage. We compared academic, emotional-behavioral and social functioning at age 10, and predictors of outcomes, in a nonreferred cohort of children recruited at age 7, between those with full-syndrome (FS) ADHD and controls with no ADHD.

METHODS:

This was a prospective cohort study with a 3-year follow-up period. Children were recruited from 43 socioeconomically diverse schools in Melbourne, Australia. Multi-informant outcomes at age 10 were academic functioning (Wide Range Achievement Test 4; Social Skills Improvement System), emotional-behavioral functioning (Strengths and Difficulties Questionnaire total), and social functioning (Strengths and Difficulties Questionnaire peer problems). Outcomes were compared across the groups by using adjusted random-effects linear regression analyses.

RESULTS:

In total, 477 children (62% male) were recruited at a mean (SD) age of 7.3 years (0.4). There were 179 participants with FS ADHD, 86 with ST ADHD, and 212 controls. Sample retention was 78.2% at 3-year follow-up. Both the FS and ST groups were functioning worse than controls on almost all outcome measures. The best predictors of outcome for children with ADHD were working memory (academic outcome, P < .001), ADHD symptom severity (emotional-behavioral outcome, parent: P < .001; teacher: P < .01), and autism spectrum disorder symptoms (emotional-behavioral outcome, parent P = .003; social outcome, parent P = .001).

CONCLUSIONS:

Children with FS and ST ADHD at age 7 experience persisting functional impairments across domains at age 10. The predictors identified at age 7 present potential targets for intervention to ameliorate impairments.

Die aktuelle Entwicklung von Wissenschaft und Forschung ist durch eine zunehmende systemimmanente Fixierung auf Sichtbarkeit gekennzeichnet, die darin zum Ausdruck kommt, dass im Vergleich zu anderen Aspekten wissenschaftlicher Tätigkeit dem Phänomen Sichtbarkeit eine zunehmend höhere Bedeutung zugeschrieben wird. Dieser Beitrag fokussiert auf Veränderungen im System Wissenschaft auf personaler Ebene. Basierend auf Leitfadeninterviews wird dabei besonderes Augenmerk darauf gelegt, wie sich dieser Wandel auf Forschende, die in diesem Umfeld agieren, auswirkt und wie diese auf neue Entwicklungen reagieren. Neben Internationalisierung und Ökonomisierung steht insbesondere die Bedeutung digitaler Medien in diesem Transformationsprozess im Fokus. Zentral dabei ist die Frage nach der Sichtbarkeit von Forschenden im Kontext der Digitalisierung und die damit einhergehenden Veränderungen.

El análisis de crecimiento de 5 híbridos de zanahoria (Daucus carota L.) se efectuó en Cipreses de Oreamuno, Cartago, con el objetivo de describir el crecimiento y la fenología del cultivo de zanahoria. El análisis de crecimiento se realizó mediante la metodología de análisis funcional. Se evaluó el área foliar y peso seco total de cada órgano de la planta, se ajustaron modelos de regresión no lineal para dichas variables, se obtuvieron los parámetros que definen las funciones matemáticas que describen el crecimiento y se representó gráficamente cada modelo para cada variable evaluada. Las variables de peso seco total y de raíz se ajustaron en la función ogística no-lineal asintótica: PS=alfa/(1+exp(-beta(x-gamma))); el peso seco de hojas y el área foliar se ajustaron en la función tipo “campana”: PS=alfa*exp(-beta(x-gamma)2). Las plantas presentaron una curva de crecimiento sigmoidal con fases bien definidas: una fase de crecimiento lento, luego una etapa de crecimiento exponen cial, seguida de una etapa de disminución del crecimiento y por último una etapa de estabilidad. La planta dedica sus primeros estados de desarrollo a establecer su maquinaria fotosintética, en competencia directa con el desarrollo radical. La raíz comienza a engrosar entre los 63 dds y los 77 dds según el híbrido, durante la etapa II de crecimiento, con una mayor proporción de asimilados destinados a la raíz, lo que conduce a un aumento en su diámetro. Finalmente, del análisis de las variables de peso seco total y área foliar, se puede establecer 2 grupos: por un lado Suprema, Esperanza y Bangor, y por otro CLX-3193 y Sirkana. El primer grupo presentó los valores más altos para dichas variables.
Manejo sostenible de la broca del café (Hypothenemus hampei) mediante poda sistemática del cafeto en Costa Rica
Authors: Rojas Mainor
Published: October 2020

Se realizaron evaluaciones en 29 cafetales de 9 localidades de Costa Rica, y se condujo un ensayo de campo, con el objetivo de estudiar el comportamiento del ataque de broca en lotes con diferentes sistemas de poda y validar el control diferenciado de la plaga en un sistema de poda por hilera cada 3 años. En sitios con poda por lote cada 3 años, la broca mostró una reducción de 48% de ataque en las ramas de 1 año respecto a las de 2 años; en lotes con poda por hilera cada 4 años, las ramas de 1 y 2 años mostraron entre 52 y 65% menos ataque que las ramas de 3 años. Un efecto similar se observó en lotes con poda por hilera cada 3 años, donde las ramas de 1 año presentaron en promedio 56% menos ataque que las ramas de 2 años. En el ensayo de campo, después de la aplicación diferenciada de insecticida, el porcentaje de frutos con brocas vivas en la hilera de 2 años fue de 0,7% en ambos tratamientos a los 90 días después de la aplicación; mientras en la hilera de 1 año ese porcentaje fue de 0,7% donde se aplicó insecticida y 1% donde no se aplicó, sin mostrar diferencias significativas entre los tratamientos. El control diferenciado de broca, en un sistema de poda por hileras cada 3 años, permitió ahorrar el 30% del tiempo de la aplicación, 40% del insecticida y 36,5% del agua utilizada para la aspersión, al aplicar solo el 33% del cafetal, y sin poner en riesgo el resto del área cultivada. Se concluyó que las podas por lote y por hilera permiten concentrar la población de brocas en áreas reducidas del cafetal, lo que facilita las labores de control.

Resulta crucial adecuar las herramientas tecnológicas basadas en sistemas de posicionamiento global a las prácticas agrícolas para mejorar la eficiencia de producción por área, incrementando la productividad. Este proyecto tiene como objetivo desarrollar una metodología de análisis georeferenciado, basado en el número de manos por racimo de una finca. El trabajo se llevó a cabo la Finca Bananera de la Universidad EARTH; la metodología consistió de varías etapas: primero, se determinó la distancia máxima de muestreo con un semivariograma, calculada en 125 m; para obtener información más precisa, el muestreo se realizó a una distancia de 80 m por 50 m; se hizo la recolección de información georreferenciada de la población en un área circular de 8 m de radio, como número de manos por racimo. Se generaron mapas del comportamiento de la productividad y la densidad poblacional en el bloque 1. Se encontró mayor área dentro del rango óptimo del número de unidades productivas por hectárea. En términos productivos el 4% (5,28 ha) del área de la finca está por debajo del punto de equilibrio financiero y el 94% está por encima del punto de equilibrio. Algunas áreas bajan su productividad cuando exceden las 1800 plantas.ha-1. Se logró desarrollar una metodología para la toma de datos a partir del índice fenológico del número de manos por racimo y de la agricultura de precisión. La herramienta identificó los puntos críticos productivos pero no los asoció a ninguna variable de suelo o climática; por lo tanto, se recomienda realizar un nuevo análisis de las zonas; incorporando otras variables de forma integrada.
Arcillas identificadas en suelos de Costa Rica a nivel generalizado durante el período 1931-2014: I. historia, metodología de análisis y mineralogía de arcillas en suelos derivados de cenizas volcánicas
Authors: Alvarado Alfredo , Mata Rafael , Chinchilla Miguel
Published: October 2020

Se resume la información disponible sobre caracterización de arcillas en suelos de Costa Rica desde 1931 hasta el presente, descrita en 84 trabajos con 520 observaciones hasta el 2014. La discusión se basa principalmente en la mineralo- gía de arcilla de los horizontes superficiales del suelo, aunque se menciona la mineralogía de los horizontes B cuando ésta es diferente a la de los horizontes A de manera relevante. Después de ubicar los datos puntuales en un mapa del país, se encontró que algunas áreas cuentan con poca o ninguna información (península de Nicoya, Zona Norte y región este de la Cordillera de Talamanca). Para el área restante la información disponible se agrupó por mineralogías de “arcilla dominante”, identificándose las mineralogías: (1) vidrio-amorfo-halloysítica (Andisoles y otros suelos con características ándicas); (2) esmectítica y de arcillas interestratificadas (Vertisoles y otros suelos con características vérticas); (3) óxidos-hidróxidos-oxihidróxidos-caolinita-gibbsita (Alfisoles, Ultisoles y Oxisoles); además de una serie importante de mineralogías mixtas en suelos de poco o ningún desarrollo edáfico (Entisoles e Inceptisoles). En el texto se discute la génesis (procesos de formación) de los principales tipos de arcilla del país, cuando se contó con suficiente información para ello.
