ADOPTION OF DECISIONS FOR CONTROL OF COMPLEX MULTI-STAGE TECHNOLOGICAL SYSTEMS UNDER CONDITIONS OF UNCERTAINTY
Authors: Kabulova E. G.
Published: December 2018

Today metallurgical production from the point of view of management and multistage character of production is complex, big system with various features of functioning of subsystems and elements. Traditional methods for the management of such systems are ineffective, as one of the main problems is the choice of optimal management decisions, taking into account current situations and limitations on changes in the values of technological parameters. One of the problems arising in the management of complex technological systems of metallurgical production is the heterogeneity of a large amount of data, which complicates the process of making effective and operational decisions in the management of production. Adequate decision-making by the expert is connected with the need to aggregate various kinds of information at different levels of the hierarchy. In addition, the operation of real complex systems of metallurgical production takes place in conditions of uncertainty of information, and to implement effective management, to organize decision support, to ensure the efficiency and accuracy of information to improve the quality of metal products and technical and economic indicators of production in this case is not possible. In this connection, the paper proposes a model of integration of heterogeneous information under uncertainty, which will take into account the measure of importance not only of individual values of technological parameters at a certain stage of production, but also a set of such parameters through the use of fuzzy measures in the integration of data. This model will improve the accuracy of determining the required values of technological parameters by taking into account all stages of production, technological operations, as well as through the use of data aggregation at each stage. The peculiarity of the developed model is the possibility of applying corrective procedures for the sequential adaptation of membership functions of fuzzy parameters.

Many controlled plants, in particular mobile robots, solve various tasks in a priori uncertain conditions. In this connection their mathematical models necessary for creation of qualitative control systems are unknown. Therefore development of design methods of adaptive control systems is actuality. The big uncertainty of this control problem makes application of adaptive systems with identification by the most expedient. In article the new analytical design method of adaptive control systems by movement of mobile robots group in the uncertainty conditions is offered. This method is focused on the decision of a task of identification of the current mathematical models of robots with the subsequent design of a control system by movement of each robot. The suggested method can be realized automatically as required. It is developed on a basis of the markov method of identification, the method of analytical design of systems with control on output and impacts, and also the standard normalized transfer functions are used. As a whole this method allows to design of the adaptive control systems with desirable qualitative properties. Trial step functions of the small intensity and the original method of digital processing of the information are used at identification. Property of system invariancy of the markov parameters and their direct connection with factors of the discrete dynamic systems transfer functions are a basis of the method of digital processing of the information. It is supposed, that the mobile robots are full or can be stabilized at all possible values of their order and parameters. The suggested method can be used for creation of control systems by the various technical plants functioning in conditions of uncertainty.

Published: December 2018

Simulation of control parameters calculating process in the problem of cooling the parts surfaces machined on CNC equipment is considered in the article. A fuzzy model for determining the transmitted to the thermoelement current to control surfaces details cooling intensity proposed in the article. The fuzzy model consists of four steps. At the first step, the calculation of the degrees of the membership functions is produced. Input membership functions are having a triangular shape, and the output variable is represented by a singleton function. The second step, the degrees of the premises of the twenty-seven fuzzy rules is calculated. The third step, the eleven levels of conclusions of fuzzy rules is calculated. At the fourth step, defuzzification a crisp value from a simplified fuzzy inference is derived. After that, the scaling ratio and the output voltage level are determined. Also the condition of equality of the collector current for the calculated value is checked. If this condition is not implemented, the level of the output voltage is recalculated, until the set condition is fulfilled. The main problem in the system operation is the voltage calculation at the microcontroller output corresponding to the required current on the thermoelement with the maximum speed. To provide voltage calculating high speed in device was made on a field-programmable gate array (FPGA).Defuzzification in the fuzzy inference is based on a simplified fuzzy inference. The explaining the essence of the proposed technical solution numerical modeling is presented in the article. Timing diagrams of the cooling control device and voltage-current conversion devices in the cooling control system are presented in the article.

Objective:to evaluate the possibilities of normobaric hypoxic training (NHT) in the human brain protection from the damaging eﬀects of oxygen defciency.

Materials and methods:the study involved 18 men, aged 19-23 years, who underwent NHT: 15 treatments daily 2-hour stay in a hypoxic gas medium (HGM) having an oxygen content 15.0 ± 0.5% (HGM-15). Beforestarting the NHT (I phase), and afer 1-2 days afer its closure (II stage) were carried hypoxic samples (staying in HGM-15) before and during which the subjects were recorded the electroencephalogram (EEG) and mental performance were evaluated (the «Route» test).

Results:when the frst hypoxic test was carried out, the subjects had a decrease in the alpha-rhythm index (on average by 10-15 %, p = 0.013) and its amplitude (by 10-12 %, p = 0.044) compared to the usual environmental conditions. At the same time, the share of low-amplitude slow waves increased (p = 0.019). Te integral indicator of the «Route» test during staying of the subjects in the HGM-15 decreased on average by 18% compared to the usual conditions (p <0.001). Te obtained data testifed about negative inﬂuence of staying in HGM -15 on the functioning of the higher parts of the brain. Afer carrying out NHT, all subjects showed a signifcant reduction in the negative reactions of spontaneous EEG to hypoxia: when the sample was repeated, the alpha-rhythm index and its amplitude did not change signifcantly (in comparison with air breathing), signs of excessive slow wave activity were absent. Reduction of the integral indicator of mental performance when staying in HGM-15 amounted to an average of only 6%.

Conclusions:NHT in the developed regime is an eﬀective means of the brain protection from the damaging eﬀect of oxygen defciency and can be used in the system of physiological training of specialists to perform tasks of activity in conditions of reduced partial pressure of oxygen.

Published: December 2018

Objective:to determine the eﬀect of the initial comorbid burden in patients with metastatic colorectal cancer (CRC) and resectable liver metastases on the development of postoperative complications, depending on the use of laparoscopic or standard open operations.

Materials and Methods:the study included 311 patients with verifed metastatic CRC T3-4N1-2M1 and resectable metastases in the liver. Depending on the organization of the surgical treatment, the patients were divided into two groups: the main group (n=161) performed laparoscopic surgical interventions and a control group (n=150) of patients with the same pathology who underwent traditional open operations. Te comorbidity was assessed by the Charlins comorbidity index, the risk of cardiovascular complications according to Goldman, the adjusted Lee index. Te eﬀect of comorbidity on postoperative complications was studied by the method of constructing conjugacy tables.

Results:in patients with metastatic RTC in class IV of the risk of cardiovascular complications according to Goldman and high cardiovascular risk in the Lee index, open surgical interventions had an advantage over laparoscopic surgery because of the risk of life-threatening cardiopulmonary pathology. In the I-III class of the risk of cardiovascular complications according to Goldman and low, as well as intermediate cardiovascular risk in Lee, the laparoscopic operations were not accompanied by an increased risk of postoperative cardiovascular complications and were accompanied, in addition to the traditional advantages of minor trauma, by reducing the complications associated with removal oncological drug, as well as infectious wound complications in the place of surgical intervention. Conclusion: when deciding whether to perform laparoscopic interventions in patients with metastatic CRC and resectable metastases in the liver, it is necessary to assess the comorbid load on the Goldman and Lee index before the operation.

O Papel da Motivação para a Qualidade da Atenção na Prática Deliberada em Performance Musical
Authors: De Carvalho Torres Eduardo
Published: December 2018

Pesquisadores em performance musical e expertise tem enfatizado a importância da motivação e da atenção para a chamada prática deliberada, negligenciando, no entanto, a discussão sobre as condições que favorecem esse estado de primazia. Entendendo ser esta uma condição importante para a qualidade da prática deliberada, por que não discutir esse assunto com mais profundidade?

Em minha pesquisa, tento demonstrar a relação entre os estados motivacionais do performer e sua capacidade de atenção. De acordo com o quadro teórico atual, as evidências sugerem que a qualidade da atenção é, ao menos em parte, regulada pelos níveis de motivação do sujeito. Meu referencial teórico considerou autores como Ericsson, Krampe e Tesch-Römer (1993), Reeve (2006), Csikszentmihaly (1997), Styles (2006), Eysenck e Keane (2010), Baddeley, Eysenck e Anderson (2015), Cohen (2014), entre outros.

Para testar minhas proposições, desenvolvi um pequeno programa experimental executado com estudantes de piano de diferentes níveis onde pude observar, entre outras coisas, suas rotinas de estudo, hábitos, gostos, histórico pessoal e profissional, aspirações, onde foi possível verificar minhas proposições. Os resultados demonstraram que existe uma clara relação entre os estados motivacionais dos indivíduos e suas respectivas habilidades atencionais. Além disso, certos níveis de motivação induzem a uma maior capacidade de focar, sugerindo que existe uma necessidade de ampliar as discussões sobre a atualização dos currículos de formação de instrumentistas, particularmente de pianistas. É essencial para a pedagogia do instrumento preparar os estudantes para superar as dificuldades relacionadas à ineficácia da atenção, visando uma maior qualidade na prática deliberada.

Published: December 2018

In this article, we examine how data producers’ and reusers’ privacy concerns shape their views about data sharing and reuse in the field of education, with an emphasis on video records of practice. We find that data producers and reusers were concerned about the risks that qualitative data, and video records of practice in particular, present to themselves, their colleagues, and the subjects represented in the data. Specifically, they emphasized risks relating to the privacy the subjects – teachers and students who appear in the videos. In response to these risks, data producers have engaged in a number of strategies to minimize risk and/or mitigate potential harm including: (1) education and training; (2) using informed consent to facilitate and/or restrict data sharing; and (3) limiting data capture/production. We discuss the implications that our findings have for digital repositories, and for efforts to facilitate the sharing and reuse of qualitative video data in education.

Published: December 2018

Since its creation nearly a decade ago, the Digital Curation Centre (DCC) Curation Lifecycle Model has become the quintessential framework for understanding digital curation. Organizations and consortia around the world have used the DCC Curation Lifecycle Model as a tool to ensure that all the necessary stages of digital curation are undertaken, to define roles and responsibilities, and to build a framework of standards and technologies for digital curation. Yet, research on the application of the model to large-scale digitization projects as a way of understanding their efforts at digital curation is scant. This paper reports on findings of a qualitative case study analysis of Indiana University Bloomingtonâ€™s multi-million-dollar Media Digitization and Preservation Initiative (MDPI), employing the DCC Curation Lifecycle Model as a lens for examining the scope and effectiveness of its digital curation efforts. Findings underscore the success of MDPI in performing digital curation by illustrating the ways it implements each of the modelâ€™s components. Implications for the application of the DCC Curation Lifecycle Model in understanding digital curation for mass digitization projects are discussed as well as directions for future research.

Published: December 2018

This paper describes the findings from a participatory prototype design project, where the authors worked with maternal and child health (MCH) researchers and stakeholders to develop a MCH metadata profile and sustainable curation workflow. This work led to the development of three prototypes: 1) a study catalogue hosted in Dataverse, 2) a metadata and research records repository hosted in REDCap and 3) a metadata harvesting tool/dashboard hosted within the Shiny RStudio environment. We present a brief overview of the methods used to develop the metadata profile, curation workflow and prototypes. Researchers and other stakeholders were participant-collaborators throughout the project. The participatory process involved a number of steps, including but not limited to: initial project design and grant writing; scoping and mapping existing practices, workflows and relevant metadata standards; creating the metadata profile; developing semi-automated and manual techniques to harvest and transform metadata; and end project sustainability/future planning. In this paper, we discuss the design process and project outcomes, limitations and benefits of the approach, and implications for researcher-oriented metadata and data curation initiatives.
Operationalizing the Replication Standard

Published: December 2018

In response to widespread concerns about the integrity of research published in scholarly journals, several initiatives have emerged that are promoting research transparency through access to data underlying published scientific findings. Journal editors, in particular, have made a commitment to research transparency by issuing data policies that require authors to submit their data, code, and documentation to data repositories to allow for public access to the data. In the case of the American Journal of Political Science (AJPS) Data Replication Policy, the data also must undergo an independent verification process in which materials are reviewed for quality as a condition of final manuscript publication and acceptance.
Aware of the specialized expertise of the data archives, AJPS called upon the Odum Institute Data Archive to provide a data review service that performs data curation and verification of replication datasets. This article presents a case study of the collaboration between AJPS and the Odum Institute Data Archive to develop a workflow that bridges manuscript publication and data review processes. The case study describes the challenges and the successes of the workflow integration, and offers lessons learned that may be applied by other data archives that are considering expanding their services to include data curation and verification services to support reproducible research.

Published: December 2018

Funders increasingly require that data sets arising from sponsored research must be preserved and shared, and many publishers either require or encourage that data sets accompanying articles are made available through a publicly accessible repository. Additionally, many researchers wish to make their data available regardless of funder requirements both to enhance their impact and also to propel the concept of open science. However, the data curation activities that support these preservation and sharing activities are costly, requiring advanced curation practices, training, specific technical competencies, and relevant subject expertise. Few colleges or universities will be able to hire and sustain all of the data curation expertise locally that its researchers will require, and even those with the means to do more will benefit from a collective approach that will allow them to supplement at peak times, access specialized capacity when infrequently-curated types arise, and stabilize service levels to account for local staff transition, such as during turn-over periods. The Data Curation Network (DCN) provides a solution for partners of all sizes to develop or to supplement local curation expertise with the expertise of a resilient, distributed network, and creates a funding stream to both sustain central services and support expansion of distributed expertise over time. This paper presents our next steps for piloting the DCN, scheduled to launch in the spring of 2018 across nine partner institutions. Our implementation plan is based on planning phase research performed from 2016-2017 that monitored the types, disciplines, frequency, and curation needs of data sets passing through the curation services at the six planning phase institutions. Our DCN implementation plan includes a well-coordinated and tiered staffing model, a technology-agnostic submission workflow, standardized curation procedures, and a sustainability approach that will allow the DCN to prevail beyond the grant-supported implementation phase as a curation-as-service model.

Authors: Koshoffer Amy , Neeser Amy E. , Newman Linda , Johnston Lisa R
Published: December 2018

This research study compared four academic librariesâ€™ approaches to curating the metadata of dataset submissions in their institutional repositories and classified them in one of four categories: no curation, pre-ingest curation, selective curation, and post-ingest curation. The goal is to understand the impact that curation may have on the quality of user-submitted metadata. The findings were 1) the metadata elements varied greatly between institutions, 2) repositories with more options for authors to contribute metadata did not result in more metadata contributed, 3) pre- or post-ingest curation process could have a measurable impact on the metadata but are difficult to separate from other factors, and 4) datasets submitted to a repository with pre- or post-ingest curation more often included documentation.
CPML PARAMETER OPTIMIZATION IN FDTD MODELING OF IMPULSIVE SOURCE
Authors: Gvozdić Branko , Đurđević Dušan , Raičević Nebojša
Published: December 2018

The convolutional perfectly matched layer (CPML) is currently, perhaps, the most efficient type of absorbing boundary condition in finite difference time domain method (FDTD) modeling of electromagnetic fields. The aim of this paper is to give a more detailed insight into parameter setting and absorption performance of CPML. In case of electromagnetic waves absorption for high-frequency impulsive source modeling, a proper choice of the CPML parameters is substantial. The numerical results show that stretching coefficient affects both absorption efficiency and dispersion. We demonstrate that, in order to eliminate dispersion, the stretching coefficient should be as small as possible. Additionally, the results have shown that a differentiated Gaussian pulse is a better choice than a regular Gaussian pulse in FDTD simulations.

Indigenous Australian artists and astrophysicists come together to communicate science and culture via art
Authors: Tingay Steven
Published: December 2018

During the International Year of Astronomy in 2009, we initiated a collaboration between astrophysicists in Western Australia working toward building the largest telescope on Earth, the Square Kilometre Array (SKA), and Indigenous artists living in the region where the SKA is to be built. We came together to explore deep traditions in Indigenous culture, including perspectives of the night sky, and the modern astrophysical understanding of the Universe. Over the course of the year, we travelled as a group and camped at the SKA site, we sat under the stars and shared stories about the constellations, and we talked about the telescopes we wanted to build and how they could sit on the Indigenous traditional country. We found lots of interesting points of connection in our discussions and both artists and astronomers found inspiration. The artists then produced <150 original works of art, curated as an exhibition called “Ilgarijiri — Things belonging to the Sky” in the language of the Wadjarri Yamatji people. This was exhibited in Geraldton, Perth, Canberra, South Africa, Brussels, the U.S.A., and Germany over the course of the next few years. In 2015, the concept went further, connecting with Indigenous artists from South Africa, resulting in the “Shared Sky” exhibition, which now tours the ten SKA member countries. The exhibitions communicate astrophysics and traditional Indigenous stories, as well as carry to the world Indigenous culture and art forms. The process behind the collaboration is an example of the Reconciliation process in Australia, successful through thoughtful and respectful engagements, built around common human experiences and points of contact (the night sky). This Commentary briefly describes the collaboration, its outcomes, and future work.

It highlights the importance of history, politics, culture and socio-economic conditions in influencing scientists' willingness to engage with lay audiences. These factors have largely been overlooked in studies of scientists' public communication behaviours.
Identificadores de los judaizantes y la resignificación de sus rituales en el contexto novohispano
Authors: Hamui Sutton Silvia
Published: December 2018

La finalidad de este trabajo es exponer la problemática con la que se enfrentaron los criptojudíos al interpretar la “Ley de Moisés”. Ante el miedo que provocaba la censura inquisitorial y el desconocimiento de su propia fe, se observa el desgaste y la transformación de la religión oficial judía, de la cual quedaron sólo rasgos aislados de los rituales sagrados ancestrales, pero resignificados para los conversos de la Nueva España. Además, se muestra cómo estos símbolos mutilados servían como fuente de conocimiento para los judaizantes, y también como identificadores usados por los delatores para inculparlos ante los tribunales inquisitoriales. El resultado fue un sincretismo que devino en el empobrecimiento de su judaísmo y la asimilación mal entendida del cristianismo.
El mercado de tierras: la historia económico-cultural y el establecimiento de los tempus económicos en el mundo rural neogranadino La provincia de Girón (1680-1770)
Authors: Bohórquez Barrera Jesús
Published: December 2018

En este trabajo se presenta una discusión sobre los ciclos de la economía colonial, tomando en cuenta las relaciones entre economía minera y rural en la Provincia de Girón durante los siglos XVII y XVIII. Se estudian dos elementos precisos: las relaciones entre la organización metodológica de la información (precios, promedios de propiedades en circulación, etc.) y la configuración de los tiempos largos de la economía, y la trascendencia de los roles de los sujetos como elementos claros de la configuración de ciertos tiempos. Con ello se plantea la inquietud de presentar un concepto diferente al del ciclo: las temporalidades que se dilatan en el juego de los engranajes generacionales. Por último, se analiza la manera como los tiempos de los juegos entre sujetos influyeron en la distribución espacial del mercado de tierras.
El diseño de las Nuevas Casas Reales de San Luis Potosí Entre lo barroco y lo académico
Authors: Hernández José Armando
Published: December 2018

Las sedes locales del gobierno virreinal, denominadas Casas Reales, fueron uno de los espacios civiles más importantes en las poblaciones novohispanas. Desde su fundación en 1592, la ciudad de San Luis Potosí no contó con unas Casas Reales dignas; por esta razón, el visitador José de Gálvez determinó en 1767 la construcción de unas Nuevas Casas Reales, acordes con la arquitectura y lustre de la ciudad. No obstante, por cuestiones tanto económicas como de gusto, fueron precisos 23 años para que uno de los diseños presentados fuera aceptado. Es así como, pasando por soluciones castrenses y coqueteos barrocos, y culminando en la sencillez y rigor de la Academia, el edificio y su diseño se circunscriben en la historia como una muestra del cambio de mentalidades, testigo de la transformación que en sustancia y esencia se estaba dando en el siglo XVIII novohispano.

El clero secular de Nueva España y la búsqueda de grados de bachiller
Authors: Aguirre Rodolgo
Published: December 2018

Este artículo compara los argumentos de un claustro universitario acerca de que no es necesario que el clero obtenga grados académicos, con la petición de un obispo para convertir su seminario en universidad. Aunque el claustro negó que los clérigos necesitaran grados, en realidad desde el siglo XVI la Iglesia tuvo interés en consolidar la fundación universitaria. Los arzobispos de México vieron en la universidad un espacio para la formación del clero, la cual les era exigida para la ordenación sacerdotal. Si bien no había ley que exigiera al clérigo medio un título universitario, en la práctica la mayor parte de la clerecía lo tuvo. Negar la relación entre la carrera eclesiástica y los grados sólo se entiende como una estrategia para evitar una segunda universidad en Nueva España que trastocara el monopolio de los grados detentado por la Universidad de México.

Federalismo y formación estatal en los antecedentes de la Revolución de la Costa. La Provincia de Santa Marta entre 1830 y 1842
Authors: Rueda Santos Rigoberto
Published: December 2018

Este artículo propone una interpretación acerca de la participación de la Provincia de Santa Marta en la Guerra de los Supremos desde los antecedentes configurados en la década anterior. Tras examinar las demandas del gobernador provincial a finales de 1839 que anticipan la aspiración federal, el ensayo se detiene en algunas de las tensiones presentadas entre las aspiraciones de los gobernantes provinciales y el poder central a lo largo de la década de 1830. El epílogo de esta situación es el pronunciamiento del cantón de Santa Marta y la reivindicación del sistema federal de gobierno al menos para las provincias de la costa Caribe que se agrupan bajo el fugaz Estado del Manzanares y que constituye el preámbulo a la Revolución de la Costa.
Consumo de carnes en zonas cálidas del Nuevo Reino de Granada: cualidades cambiantes, siglos XVI y XVII
Authors: Saldarriaga Gregorio
Published: December 2018

El artículo trata sobre la producción y consumo de carne de cerdo y de algunos animales americanos en zonas cálidas de alto tráfico comercial del Nuevo Reino de Granada, durante los siglos XVI y XVII. El objetivo es mostrar que el aumento en el consumo de carnes, con respecto a la dieta europea mediterránea, producía cambios en las concepciones de la vida que tenía la sociedad colonial. Asimismo, se muestra que en un ambiente de dominación hispánica, los usos indígenas tradicionales de consumo de ciertos animales americanos se transformaban drásticamente, pasando a ser utilizados y aprovechados para el abastecimiento de las ciudades, villas y puertos. La información sobre la cual se basa esta investigación proviene del fondo Visitas del Archivo General de la Nación (Bogotá) y de fuentes impresas, entre las cuales cabe destacar algunas que no han sido frecuentes en los estudios sobre el Nuevo Reino de Granada.

“El mayor escarnio que en esta tierra ha habido”. Abuso de poder, persecución y violencia en torno a la fundación del Carmelo de Santa Fe de Bogotá (1597-1608) .
Authors: Brizuela Molina Sofia
Published: December 2018

Los estudios sobre la fundación de conventos permiten una aproximación excepcional a los conflictos de la sociedad donde se establecen. En este artículo, el surgimiento de un claustro femenino en Santafé (1606) revela el conflicto de poder latente entre los descendientes de los primeros conquistadores y los nuevos funcionarios de la Audiencia. Más allá de los aspectos relativos a la espiritualidad, el caso estudiado deja apreciar el entramado de vínculos que unían los linajes de los primeros conquistadores, como también sus esfuerzos y estrategias para conservar los privilegios y la primacía social que veían amenazada por la política de la Corona y sus funcionarios.
La paz interior y el testamento. El testar como acto liberador, siglo XVII
Authors: Rojas Vargas Astrid Guiovanna
Published: December 2018

El artículo se aproxima al testamento colonial, describiéndolo y analizando su estructura interna y, posteriormente, observando el acto de testar, no solo como una convención notarial, sino como un acto religioso, última oportunidad de salvar el alma para la vida eterna y de liberar la conciencia del peso de la vida en el mundo, lo cual muestra que testar era un acto liberador. El trabajo se realizó mediante la combinación de métodos cuantitativos y cualitativos, con una muestra de 50 testamentos registrados en Santafé durante el siglo XVII. El uso de fuentes complementarias permitió una mejor comprensión de la forma de morir en esta época y las razones del acto de testar.
La limpieza de sangre en el Colegio de Abogados de Caracas a finales del siglo XVIII
Authors: Almarza Villalobos Ángel Rafael
Published: December 2018

El discurso de la limpieza de sangre es esencial para la comprensión de los valores de las sociedades hispanas de la época colonial. En este artículo se muestra cómo un discurso originado en el continente europeo pasó a ser la base del sistema de estratificación social en el nuevo orden colonial y se analiza el impacto de la transferencia de ideas desde España a las sociedades coloniales, a partir del estudio del Colegio de Abogados de Caracas. El concepto de limpieza de sangre en la provincia de Caracas fue distinto del establecido en la metrópolis. En estas tierras, la limpieza de sangre fue preocupación de todos los grupos sociales que conformaban la provincia durante el siglo XVIII y elemento fundamental para que la élite criolla mantuviera el control de las instituciones civiles y eclesiásticas.

Se hace un detallado balance bibliográfico sobre las obras del historiador Juan Friede (1901-1990), que tratan sobre el adelantado Gonzalo Jiménez de Quesada, fundador de la ciudad de Santafé de Bogotá. También se hace una extensa revisión de las investigaciones que se han escrito sobre la vida y obra de este conquistador por parte de otros investigadores, señalando los aportes que cada uno ha realizado y la importancia de los trabajos de Friede como pionero del estudio de la conquista del Nuevo Reino de Granada y la problemática indígena colombiana, con base en la documentación guardada en el Archivo General de Indias (Sevilla), aprovechando una reciente reedición del libro El adelantado don Gonzalo Jiménez de Quesada (1979).
The impact of reinsurance for insurance companies
Authors: Bressan Silvia
Published: December 2018

The study provides empirical evidence for the effect of reinsurance on solvency, profitability, and taxes of primary insurers. Our main finding is that primary insurers increasing in the use of reinsurance exhibit lower capital ratios. This impact involves the segments of health insurance, composite insurance, title insurance, and non-life insurance. Our interpretation is that reinsurance and capital can be seen as substitutes for improving solvency. This implies that, by sharing their risk with reinsurers, primary insurers can benefit from a relief on capital. Additional outcomes display an important relationship between demand and supply of reinsurance at the firm level, as we observe that, growing in the used reinsurance; primary insurers are more prone to providing reinsurance to other firms.
