Abstract. To investigate the aging impact on sources, volatility, and viscosity of organic aerosols (OA) in the Chinese outflows, a high-resolution time-of-flight aerosol mass spectrometer (HR-AMS) coupled with a thermodenuder (TD) was deployed in the spring of 2018 in Dongying, which is a regional receptor site of metropolitan emissions in North China Plain (NCP). The average mass concentration of PM1 was 31.5 ± 22.7 μg m–3, which was mainly composed of nitrate (33 %) and OA (25 %). The source apportionment results show the OA was mainly contributed by oxygenated OA (OOA) from secondary sources, including background-OOA (33 %) representing a background concentration of OA (2.6 μg m–3) in the NCP area, and transported-OOA (33 %) oxidizing from urban emissions. The other two factors include aged hydrocarbon-liked OA (aged-HOA, 28 %) from transported vehicle emissions and biomass burning OA (BBOA, 5 %) from local open burnings. The volatility of total OA (average C* = 3.2×10–4 µg m–3) in this study is generally lower than those in previous field studies, which is mainly due to the high OA oxidation level resulting from aging processes during transport. The volatilities of OA factors follow the order of background-OOA (average C* = 2.7×10–5 μg m–3) < transported-OOA (3.7×10–4 μg m–3) < aged-HOA (8.1×10–4 μg m–3) < BBOA (0.012 μg m–3), indicating the probable existence of oligomers. The viscosity estimation suggests that the majority of ambient OA in this study behaves as semi-solid (60 %), liquifies at higher RH (21 %), and solidifies (19 %) during noon time when the RH is low and the oxidation level is high. Finally, the estimated mixing time of OA varies dramatically from minutes at night to years in the afternoon, emphasizing the necessity to consider its dynamic kinetic limits when modeling OA. In general, the overall results of this study improve the understanding of the aging impact on OA volatility and viscosity.

Abstract. The Atmospheric Carbon Observations from Space (ACOS) retrieval algorithm has been delivering operational column-averaged carbon dioxide dry-air mole fraction (XCO2) data for the Orbiting Carbon Observatory (OCO) missions since 2014. The ACOS Level 2 Full Physics (L2FP) algorithm retrieves a number of parameters, including aerosol and surface properties, in addition to atmospheric CO2. Past analysis has shown that while the ACOS retrieval meets mission precision requirements of 0.1–0.5 % in XCO2, residual biases and some sources of error remain unaccounted for (Wunch et al., 2017; Worden et al., 2017; Torres et al., 2019). Forward model and other errors can lead to systematic biases in the retrieved XCO2, which are often correlated with these additional retrieved parameters. The characterization of such biases is particularly essential to urban- and local-scale emissions studies, where it is critical to accurately distinguish source signals relative to background concentrations (Nassar et al., 2017; Kiel et al., 2021). In this study we explore algorithm-induced biases through the use of simulated OCO-3 Snapshot Area Mapping (SAM) mode observations, which offer a unique window into these biases with their wide range of viewing geometries over a given scene. We focus on a small percentage of SAMs in the OCO-3 vEarly product which contain artificially strong across-swath XCO2 biases spanning several parts per million, related to observation geometry. We investigate the causes of swath bias by using the timing and geometry of real OCO-3 SAMs to retrieve XCO2 from custom simulated L1b radiance spectra. By building relatively simple scenes and testing a variety of parameters, we find that aerosol is the primary driver of swath bias, with a complex combination of viewing geometry and aerosol optical properties contributing to the strength and pattern of the bias. Finally, we seek to understand successful mitigation of swath bias in the OCO-3 version 10 data product. Results of this study may be useful in uncovering other remaining sources of XCO2 bias, and may help minimize similar retrieval biases for both present missions (GOSAT, GOSAT-2, OCO-2, OCO-3, TanSat) and future missions (e.g. MicroCARB, GeoCarb, GOSAT-GW, CO2M).

Abstract. The Hydrology Meteorology and Complexity laboratory of École des Ponts ParisTech (http://hmco.enpc.fr, last access: 16 August 2022) has made a data set of high-resolution atmospheric measurements available, which is of interest for the atmospheric science community. It comes from a campaign carried out in the framework of the Rainfall Wind Turbine or Turbulence project (RW-Turb; supported by the French National Research Agency, grant no. ANR-19-CE05-0022) on a meteorological mast installed at a wind farm located approx. 110 km southeast of Paris in France. In total, 3 months of data, covering the spring period from 1 March to 1 June 2021, are made available. We used six devices, namely two 3D sonic anemometers (manufactured by Thies), two mini meteorological stations (manufactured by Thies), and two disdrometers (Parsivel2, manufactured by OTT). They are installed at two heights (approx. 45 and 80 m), which enables us to monitor potential effects of altitude. The temporal resolution is of 100 Hz for the 3D sonic anemometers, 1 Hz for the meteorological stations, and 30 s for the disdrometers. A multifractal analysis is implemented to assess the effective resolution of the devices, and it is suggested that the anemometers and stations are able to measure expected variability only down to 1 and 16 s, respectively.

Fiabilidad del Uso de Localizadores Apicales y Examen Radiográfico en Endodoncia a Pacientes de la Clínica Odontológica Univalle 2017-2018.
Authors: Zamorano Vilar Cinthya Fabiola
Published: August 2022

La correcta determinación de la longitud de trabajo de los conductos radiculares permite que el tratamiento endodóntico sea realizado dentro de los límites adecuados. Para establecer la misma, se ha empleado tradicionalmente la técnica radiográfica de Ingle, que en algunos casos no proporciona la ubicación exacta de la constricción apical, mientras que el localizador apical permite establecer con mayor exactitud la longitud de los conductos radiculares.Se realizó una investigación de tipo prospectivo, descriptivo y longitudinal con el objetivo de determinar la fiabilidad de los localizadores apicales y la técnica radiográfica de Ingle en endodoncias uniradiculares en pacientes de la Clínica Odontológica Univalle 2017-2018. La población estuvo conformada por 50 piezas dentarias; se llenaron fichas de cotejo e historias clínicas de endodoncia, los datos fueron transcritos en el programa Excel y tabulados en el paquete estadístico SPSS v.18.Los resultados obtenidos evidencian de forma objetiva que la técnica radiográfica de Ingle con un 40% de precisión no debe utilizarse aisladamente para determinar la longitud de trabajo de los conductos radiculares, esta debe ser complementada con el uso de un localizador apical, como el Propex Pixi, que registró un 64% de exactitud, resultando ser el más fiable, ya que su empleo agiliza el tratamiento endodóntico y disminuye el número de exposiciones del paciente a la radiación.
Capítulo 1. El anhelo de una utopía: El cine postsecular de Robert Guédiguian
Authors: Alzola Cerero Pablo
Published: August 2022

Europa ha estado cautivada, durante largos años, por la idea ilustrada de la razón como garante de certezas objetivas. A partir de la segunda mitad del siglo XX, señala Charles Taylor en A Secular Age (2007: 551), esta idea se ha ido quebrantando, dando paso a una “visión postsecular” por la cual algunas dimensiones de la conducta humana (como la creencia, la idea de lo sagrado o la conexión afectiva con el mundo) adquieren un lugar relevante en la vida de las personas y de las pequeñas comunidades. Tal y como han estudiado recientemente John Caruana y Mark Cauchi en Immanent Frames (2018: 5), muchas películas de los últimos años logran transmitir lo que significa “habitar el espacio abierto postsecular”. Entre estas películas, este capítulo centra su atención en algunos filmes del cineasta Robert Guédiguian donde su ateísmo de raíces marxistas convive con un claro interés por reivindicar la idea de lo sagrado y su capacidad para crear vínculos en las pequeñas comunidades que retrata. El director marsellés explicaba en una entrevista que “lo sagrado” se hace presente en cada “expresión absoluta de humanidad” (Pérez Colomé, 2003: 37). En este sentido, la escena Mi padre es ingeniero (Mon père est ingénieur, 2004) donde los protagonistas interpretan a los personajes de un Belén viviente, a la espera de un nuevo nacimiento, es una forma elocuente de subrayar el papel de lo sagrado en las relaciones que tejen la pequeña comunidad de familiares y amigos.

Capítulo 3. Visiones románticas tardías de Europa: cruzados, La danza de la muerte y la peste en El séptimo sello (Ingmar Bergman, 1957)
Authors: Gutiérrez Delgado Ruth
Published: August 2022

Una parte de Europa huye de la muerte. La otra se pregunta sobre cómo sobrevivirle. La presencia de la muerte ha sido icono del arte europeo y tema de la filosofía occidental desde las primeras imágenes que la representaron como un claro signo de su identidad. Una concepción específica de ésta se fragua durante la Edad Media en Europa. Frente a la idea oriental de liberación, según la tradición, el occidental tiene sed de inmortalidad, “sed de ser para siempre”. Como un río que arrastra sedimentos, esa forma específica de entender la muerte se representa en “visiones lúgubres” que recorren la historia de Europa, marcando una tendencia espiritual común y ofreciendo una comprensión de la existencia y de la muerte que se acrisola con la expansión de la peste. Esta última cambió la vida europea y sirvió de factor aglutinante desde el punto de vista religioso, político y geográfico. La Cristiandad se ve asolada por la misma enfermedad, a la vez que responde a similares designios. En particular, con su visión romántica estilizada, Ingmar Bergman, en El séptimo sello (1957) aglutina los tres elementos clave del ser europeo en ciertos elementos icónicos y argumentales de su filme, como son la pregunta sobre la vida eterna, la vida como peregrinaje y la conciencia de culpa. De este modo, la película en sí resulta icónica y exponencial. Respecto a la iconografía, la obra de teatro medieval La danza de la muerte, la figura del caballero o peregrino que regresa de las Cruzadas en Palestina y la Muerte jugando al ajedrez son referenciales para explicar esta mitificación de la identidad europea.

Capítulo 5. La metrópolis humanizada. Relaciones estéticas y ideológicas entre Manhatta y las sinfonías urbanas europeas
Authors: Latorre Izquierdo Jorge , Jiménez González Marcos
Published: August 2022

Estados Unidos se adelantó a Europa en la utilización directa y sin prejuicios del cine y la fotografía, medios urbanos por excelencia. La Straight Photography neoyorkina influyó en la Nueva Objetividad, y Manhatta (Sheeler, Strand, 1921) inspiró obras como Berlín, sinfonía de una ciudad (1927, Ruttman) y El hombre de la cámara en movimiento (1929, Vertov). Sin embargo, la fuerte influencia que las artes plásticas tradicionales ejercían en la fotografía y el cine europeos dio como resultado una mirada ambigua a las ciudades modernas, incluso cuando no todos los males de la industrialización despersonalizadora parecían encarnarse en ellas. Películas como Metropolis de Fritz Lang (1927) participan de esta mirada confusa, que está también presente en la pintura expresionista Metrópolis de Otto Dix (1929); y, de un modo más velado, en otras sinfonías urbanas cinematográficas como La calle (Karl Grüne, 1923) o Solo las horas (Alberto Cavalcanti, 1926). Incluso las visiones utópicas que futuristas italianos y constructivistas rusos dejaron de la gran urbe moderna, aunque se acercan más a una visión sin prejuicios de la metrópolis, lo hacen desde una ideología que dista mucho de la aproximación realista o verista americana. En este artículo se analizan con detalle las relaciones existentes entre los ejemplos mencionados y otros hitos del arte visual vinculado tanto con la ciudad moderna como con los nuevos lenguajes que surgen estrechamente vinculados a ella, la fotografía callejera y el cine urbano más documental.

Capítulo 8. Dos fábulas europeas de Aki Kaurismäki: El Havre (2011) y El otro lado de la esperanza (2017)
Authors: Sánchez-Escalonilla Antonio
Published: August 2022

Hacia el final de su carrera cinematográfica, el cineasta finlandés Aki Kaurismäki se ha aproximado a las odiseas de migrantes ilegales y refugiados con dos títulos memorables: El Havre (2011) y El otro lado de la esperanza (2017). Con este último filme, Kaurismäki anunció su despedida como director y resulta significativo que en sus dos últimos títulos se establezca una comparación entre protagonistas migrantes y nativos europeos, todos ellos unidos por una necesidad común de reunión familiar que sin embargo contrasta con la desintegración que afecta a la sociedad de acogida. En estos dos títulos, el cineasta plantea con su peculiar estilo sensorial dos fábulas con tintes de realismo mágico que abundan en el humanismo de las personas con independencia de su procedencia cultural, al tiempo que emplea una clave humorística digna de Lubitsch o Tati para realizar un diagnóstico sobre la identidad incierta de los huéspedes europeos, ya vivan en Francia o en Finlandia: dos extremos del continente.

EFFECTS OF EVEN FUNCTIONAL GROUP DISTRIBUTION IN EMULSION STYRENE–BUTADIENE RUBBER PREPARED BY REVERSIBLE ADDITION–FRAGMENTATION CHAIN TRANSFER POLYMERIZATION ON THE PROPERTIES OF SILICA-FILLED COMPOUNDS
Authors: Song Sanghoon , Hwang Kiwon , Kim Donghyuk , Ryu Gyeongchan , Ahn Byungkyu , Jeon Heung Bae , Chung Sungwook , Kim Wonho
Published: August 2022

Recently, considerable attention has been paid to the development of new functionalized polymers to improve the fuel efficiency of vehicles by reducing the rolling resistance of tires to adhere to strict CO2 emission regulations. Accordingly, multifunctionalized (MF) reversible addition–fragmentation chain transfer (RAFT) emulsion styrene–butadiene rubbers (ESBR) were synthesized, in which chain-end and in-chain functionalization were performed simultaneously by introducing a third monomer (glycidyl methacrylate; GMA) using RAFT polymerization. Compared with GMA ESBR, in which GMA is introduced as a third monomer by conventional radical polymerization (CRP), there was an even distribution of GMA per chain in the MF-RAFT ESBR. After preparing the silica-filled compounds, vulcanizate structure analysis and mechanical property evaluation of the compounds were performed. The MF-RAFT ESBR prepared by RAFT polymerization exhibited superior in-chain functionalization efficiency compared with GMA ESBR prepared by CRP because of the even distribution of GMA and higher crosslink density. Consequently, MF-RAFT ESBR compound showed superior silica dispersion, abrasion resistance, and lower rolling resistance compared with the GMA ESBR compound.
Rosacea: An Overview
Authors: E Shanees.
Published: August 2022

The National Rosacea Society (NRS) designates April as Rosacea Awareness Month to educate the public on the impact of the chronic and widespread facial disorder that is estimated to affect more than 16 million Americans1. The goal of Rosacea Awareness Month is to spread public education on this disease so that more people who may have rosacea seek medical help before it gets worse, and so those whose lives are affected can find greater public acceptance and understanding.1 Rosacea is a chronic inflammatory skin condition that usually affects the face and fortunately there is a range of medical therapies that may effectively address each individual case2. Through habit, many patients may unknowingly continue with therapy that is not as effective as it could be, when there may be newer medications that achieve more successful results as well as therapy combinations that offer excellent synergistic effects.2

This work is part of a project that aims to design and develop personalized products, using additive manufacturing technology (commonly 3D printing), to support individuals with physical limitations in learning a musical instrument. An exploratory case study is approached that intends to develop an artifact to aid the learning of violin by an individual with a malformation in the left upper limb. The initial geometry, adapted to the user's anatomy, was obtained using molding paste. From there, we advanced to the digital model using 3D scanning methods and 3D modeling techniques. Finally, two prototypes were produced, using additive manufacturing techniques using FFF and Polyjet technologies. The evaluation of the prototypes produced was carried out through tests with the user, verifying the need to make adjustments. In the next stages of the work, it is intended to obtain a fnal artifact completely adapted to the user's anatomy that allows, facilitates, and helps the learning of the instrument. It is then intended to apply and systematize the knowledge developed through this exploratory case in similar cases.

The traveling salesman problem is a classic problem in combinatorial optimization. This problem is to find the shortest path that a salesman should take to traverse through a list of cities and return to the origin city. The list of cities and the distance between each pair are provided. It is an NP-complete problem i.e., a class of computational problem for which no efficient solution algorithm has been found, presently there is no polynomial solution available. In this paper, we try to solve this very hard problem using various heuristics such as Simulated Annealing, Genetic Algorithm to find a near-optimal solution as fast as possible. We try to escape the local optimum, using these advanced heuristic techniques.

The Impact of Climate Change on Russian Agriculture and Implications for Global Food Security
Authors:   Department of Political Science, Southern Methodist University, Dallas, TX 75275-0117, USA, Wegren Stephen K.
Published: August 2022

Although Russia’s grain growing regions have experienced episodic droughts, the financial impact of climate change has to date been modest when measured in terms of value of production lost. As industrial agriculture continues to emit greenhouse gases, the impact of climate change will intensify, making Russia’s southern regions drier and hotter, and potentially forcing a structural shift in production northward, an event that will lead to lower yields and grain output. The sustainable sector in Russia’s agricultural system is not able to compensate for lower grain output in the south, nor is it able to feed the nation or ensure food security across the full spectrum of commodities that consumers expect. The prospect of Russia as a declining grain power impacts the dozens of nations that import Russian grain, most notably authoritarian regimes in the Middle East.

Air pollution is a particularly important problem in most countries right now because of its terrible effects on both the environment and human health. Big cities are most impacted because of the country’s quick industrial and economic development. In this paper, the authors proposed various regression model for the prediction of air quality including decision tree regressor, MLP regressor, SVR, random forest regressor, and K-Neighbors regressor. The air quality dataset, in Itally cities, is used for training and evaluation the proposed model. The results show that there is a decrease in RMSE, MAE, MBE, R, R2, RRMSE, NSE, and WI when compared to the traditional methods.

Authors: Purcia Erwin , Velarde Angelo
Published: August 2022

This study examined the extent of implementation of the Student Registration and Records Management Services as basis for student Academic Record Digitization among three (3) private schools in the Global South. Utilizing descriptive-evaluative study, the simple random sampled respondents evaluated the services of the SRMMO with a researcher-made questionnaire validated through content validity. Analyzed through frequency and percentage distribution, weighted mean, Kruskall Wallis Test for significant difference, Fisher’s Exact Test and Kendall tau_b for significant relationship, results revealed that the majority of the respondents moderately felt the problems encountered with the SRRMO services specifically on lack of admission requirements and non-observance of enrolment schedule. The researcher recommends therefore that a more accessible and convenient enrolment scheme be implemented among schools. Hence, Digitization of students’ registration and records shall be instituted.

Published: August 2022

Background: The study aims to evaluate the clinical presentation, type of foreign body, mode of insertion, and management of intravesical foreign bodies in patients treated at our hospital.
Material and Methods: This was a retrospective study conducted between January 2019 to December 2020. Twelve patients underwent treatment for an intravesical foreign body at Srirama Chandra Bhanja Medical College and Hospital, Cuttack, Odisha, India..
Results: A total of twelve patients were treated for a foreign body in the urinary bladder. All the patients vary in age group starting from 20 to 72 yrs. Among the total of twelve patients, 5 were female whereas 7 were male patients. Patients were presented with the symptoms like dysuria, frequency, hematuria, lower abdominal pain, burning micturition. Among these twelve patients, two patients had self-inflicted foreign bodies, one pencil and the other was a stick. One patient had thread, and two female patient had IUD.The remaining 7 patients were old aged male had a piece of foley catheter in the urinary bladder. Among all these 12 patients, only two patients were treated with open procedure i.e suprapubic cystolithotomy as foreign bodies (IUD and piece of foley) lead to calculus formation over it. Rest all patients were treated with endoscopic removal of a foreign body under either local anaesthesia or Spinal anaesthesia.
Conclusions: Endoscopic retrieval of Foreign Body is always preferred and safe approach. Removal of the foreign body without injury to the urinary bladder or the urethra gives a good outcome.

Published: August 2022

Background: India represents 3% related to the global malaria problem. Early diagnosis and treatment that are complete alongside preventive measures are modalities essential to managing the situation. Rapid diagnostic tests (RDTs) and polymerase chain reaction (PCR) that are malaria that is real-time be used to obtain an exceedingly really very early diagnosis in acutely febrile customers.

Aims and Objectives: This study aims to gauge the effectiveness of RDT bloodstream that is utilized entire from clients clinically suspected of malaria and compare it with real-time PCR.

Materials and Methods: The cross-sectional study is observationally done and made up of 158 patients admitted to Index Hospital, Indore, having a serious illness that is febrile and medical suspicion of malaria. RDT for malaria antigen and PCR that are real-time done in the bloodstream that is whole examples depending on kit guidelines.

Results: There exists a difference that is significant the nice and examples which are negative by both techniques. Fast P = test is diagnostic PCR that is real-time RDT has been good in 62 (44%) clients, whereas, real-time PCR detected the parasite in 136 (91%) customers. RDT was in reality negative for malaria antigen in 16 (12.8%) consumers, in whom RT-PCR was good. RDT failed to identify Plasmodium falciparum antigen in RT-PCR samples that can be good. RT-PCR indicates basic greater sensitiveness (82.4–95% CI 79.2–84.5%) in diagnosing malaria set alongside the quick test is an antigen. The sensitiveness of RT-PCR in detecting P. falciparum had been also high (74.2%, 95% CI 71.4–77.2). This has greater specificity than RDT in detecting P. falciparum disease (91.3%, 95% CI 89.4–95.4) in detecting P. falciparum than RDT.

Conclusion: RT-PCR has better efficacy to look for the presence of malaria parasites in acutely clients being febrile remain undiscovered by RDT. Therefore, it might be helpful for the verification of diagnoses and studies which are epidemiological.

There has been a significant shift in the educational and employment scenario in recent years. Employers used to prioritize individuals with a strong academic record and relevant work experience, but today, persons with superior soft skills have surpassed them. It is typical to discover that graduating students lack the necessary abilities to work effectively in a corporate environment. Recruiters believe that new hires lack soft skills such as the capacity to effectively communicate, think creatively, solve problems independently, work well with others, and act professionally. This is one of the main reasons why many students, even those with relevant degrees, find it difficult to find work. This can lead to students questioning the practical worth of the many professional degrees that are offered in contemporary times. To close this gap, the field of training and development has developed a rapidly expanding and specialized sector known as “soft skill training.” Both technical and soft skill development are viewed as essential for an employee’s efficacy and success at work. Researchers claim that learning soft skills is more important and critical for professional development than learning technical abilities, and as a result, it is considered one of the most in-demand core talents for organization growth and development. The purpose of this article is to highlight some of the practical implications of soft skill training in bridging the gap between industry needs and curricular gaps. It also tries to look into the influence of soft skill training in terms of its importance, utility, and subsequent competence development.
Papel del Acceso Abierto en el surgimiento y consolidación de las revistas arbitradas en América Latina y el Caribe
Authors: Delgado Troncoso Jorge
Published: August 2022

Propósito: Analizar el papel del acceso abierto in el crecimiento de revistas arbitradas en América Latina (AL&C) en los ámbitos nacional, regional y global. Métodos: La información provino de dos fuentes: 1) seis importantes bases de datos/índices (OpenDOAR, DOAJ, OJS, Dialnet, SciELO y RedALyC; 2) Notas de 175 entrevistas a profundidad efectuadas entre 2008 y 2010 con editores de revistas, autoridades universitarias, personal gubernamental, agentes de organizaciones internacionales y otros expertos. Las entrevistas se realizaron en Argentina, Brasil, Chile, Colombia, México, Uruguay y Venezuela. Las bases de datos/repositorios son usadas para describir la presencia de revistas latinoamericanas por región y país. Son organizados en tablas y analizados descriptivamente. Resultados: SciELO tenía 816 revistas, 21.324 fascículos y 314.758 documentos/artículos; RedALyC tenía 758 revistas, 14.381 fascículos y 177.017 artículos. Dialnet incluía 7.168 revistas, 3.246.415 documentos y 2.230.929 artículos. 1.190 revistas (18.52%) de AL&C formaban parte de DOAJ. Colombia es el país con el segundo mayor número de revistas en RedALyC después de México y en SciELO después de Brasil. Conclusión: AL&C tiene una fuerte presencia de revistas de acceso abierto en repositorios internacionales y regionales, lo que aumenta la visibilidad de las publicaciones de la región y la posibilidad de desarrollar redes académicas. Directorios regionales como Latindex y repositorios/índices como RedALyC y SciELO han tenido un gran impacto en el desarrollo de las revistas latinoamericanas. Dos factores parecen estar apoyando el surgimiento de un modelo de publicación académica en AL&C: la publicación open Access y los repositorios e índices/bases bibliográficos regionales.
Scholarly communication strategies in Latin American´s research-intensive universities
Authors: Alperin Juan Pablo , Fischman Gustavo E. , Willinsky John
Published: August 2022

Universities engaged in producing high quality research have been in existence for centuries in Latin America, but only in the last two decades has the research-intensive model become the standard to be achieved by most public universities in the region. The increased emphasis on scholarly publication in the region has coincided with the rise of the Internet and with the emergence and growth of the Open Access (OA) movement. It is in this context, we explore three main issues: 1. How OA has been understood and incorporated into the publishing practices of faculty in research-intensive universities; 2. How OA has been understood and incorporated into the assessment practices of the national systems of Research and Development (R&D); and 3. How can we understand the dynamics of convergence between the growth of research and growth of OA in the region. We find that the inclusion of SciELO and RedALyC in the evaluation systems of the research-intensive university and of R&D national systems has given prominence to OA in the region and that this has, in turn, given credence to the evaluation practices of such OA initiatives. While it is impossible to determine direct causation between these OA initiatives (and associated technologies) on the quantity and quality of Latin American research, we conclude that they have been a crucial mechanism of support for researchers, universities, and for national systems of innovation.
