Economía del conocimiento para el marketing con base en el sexo con base a estrategias de ventas
Authors: Duarte Rey Diego Mauricio 
Published: April 2021

El propósito de la revisión fue analizar la sexualidad como uno de los instintos primarios del ser humano usados en el marketing. El hecho de reproducirse implica conseguir una pareja con el fin de querer perseverar la esencia y características propias de una generación junto a ella, para posteriormente conseguir que esa nueva generación evolucione a una mejor. El método utilizado fue el documental y descriptivo ya que se realizaron una serie de revisiones bibliográficas sobre el tema para analizar y describir los diferentes escenarios que en el transcurso del tiempo se han utilizado en este contexto. Teniendo como resultado que la sexualidad puede generar un gran rendimiento comercial en las industrias, pero si las industrias lo utilizan en exceso es muy probable que ese rendimiento positivo decrezca rápidamente convirtiéndose en un dolor de cabeza para algunos sectores sin embargo la importancia para las compañías es fundamental y es por eso que se sigue trabajando en esta línea estratégica.

ABSTRACTThis study investigates the use of neural networks for data assimilation of local data in the WRF model in Rio de Janeiro, Brazil. Surface and upper-air data (air temperature, relative humidity and wind speed and direction) from airport stations and 6-hour forecast from WRF are used as input for the model and the 3D-Var analysis for each grid point is used as target variable. Periods of 168h from 2014 and 2015 are used with 6h and 12h assimilation cycles for surface and upper-air data, respectively. The neural network model was built using the Multi-Particle Collision Algorithm (MPCA) where different topologies are tested until the optimum solution is found. Results show that the neural network is able to emulate the 3D-Var with root mean squared error (standard deviation), respectively, of 0.31 K (0.37 K), 3.10% (4.04%), 0.63 ms-1 (1.05 ms-1), 1.10 ms-1 (1.56 ms-1) for air temperature, relative humidity, u-component of the wind and v-component of the wind. Also, the results show the neural network method is able to run 71 times faster than the conventional method under similar hardware configurations. Redes Neurais Artificiais para Assimilação de Dados no Modelo WRF no Rio de Janeiro, BrazilRESUMOEste estudo investiga o uso de redes neurais para assimilação de dados locais no modelo WRF no Rio de Janeiro. Dados de superfície e do ar superior (temperatura do ar, umidade relativa e velocidade e direção do vento) das estações do aeroporto e previsão de 6 horas do WRF são usados como entrada para o modelo, e a análise 3D-Var para cada ponto da grade é usada como variável destino. Períodos de 168h de 2014 e 2015 são utilizados com ciclos de assimilação de 6h e 12h para dados de superfície e do ar superior, respectivamente. O modelo de rede neural foi construído usando o algoritmo de colisão de partículas múltiplas (MPCA), onde diferentes topologias são testadas até que a solução ideal seja encontrada. Os resultados mostram que a rede neural é capaz de emular o 3D-Var com raiz do erro quadrático médio (desvio padrão) de 0,31 K (0,37 K), 3,10% (4,04%), 0,63 ms -1 (1,05 ms -1), 1,10 ms -1 (1,56 ms -1) para temperatura do ar, umidade relativa, componente u do vento e componente v do vento. Além disso, os resultados mostram que o método de rede neural é capaz de rodar 71 vezes mais rápido que o método convencional em configurações de hardware semelhantes.
Extending the usage of graphics processing units on the cloud for cost savings on seismic data regularization
Authors: Okita Nicholas Torres , Coimbra Tiago A. , Ribeiro José , Tygel Martin 
Published: April 2021

ABSTRACT. The usage of graphics processing units is already known as an alternative to traditional multi-core CPU processing, offering faster performance in the order of dozens of times in parallel tasks. Another new computing paradigm is cloud computing usage as a replacement to traditional in-house clusters, enabling seemingly unlimited computation power, no maintenance costs, and cutting-edge technology, dynamically on user demand. Previously those two tools were used to accelerate the estimation of Common Reflection Surface (CRS) traveltime parameters, both in zero-offset and finite-offset domain, delivering very satisfactory results with large time savings from GPU devices alongside cost savings on the cloud. This work extends those results by using GPUs on the cloud to accelerate the Offset Continuation Trajectory (OCT) traveltime parameter estimation. The results have shown that the time and cost savings from GPU devices’ usage are even larger than those seen in the CRS results, being up to fifty times faster and sixty times cheaper. This analysis reaffirms that it is possible to save both time and money when using GPU devices on the cloud and concludes that the larger the data sets are and the more computationally intensive the traveltime operators are, we can see larger improvements.Keywords: cloud computing, GPU, seismic processing. Estendendo o uso de placas gráficas na nuvem para economias em regularização de dados sísmicosRESUMO. O uso de aceleradores gráficos para processamento já é uma alternativa conhecida ao uso de CPUs multi-cores, oferecendo um desempenho na ordem de dezenas de vezes mais rápido em tarefas paralelas. Outro novo paradigma de computação é o uso da nuvem computacional como substituta para os tradicionais clusters internos, possibilitando o uso de um poder computacional aparentemente infinito sem custo de manutenção e com tecnologia de ponta, dinamicamente sob demanda de usuário. Anteriormente essas duas ferramentas foram utilizadas para acelerar a estimação de parâmetros do tempo de trânsito de Common Reflection Surface (CRS), tanto em zero-offset quanto em offsets finitos, obtendo resultados satisfatórios com amplas economias tanto de tempo quanto de dinheiro na nuvem. Este trabalho estende os resultados obtidos anteriormente, desta vez utilizando GPUs na nuvem para acelerar a estimação de parâmetros do tempo de trânsito em Offset Continuation Trajectory (OCT). Os resultados obtidos mostraram que as economias de tempo e dinheiro foram ainda maiores do que aquelas obtidas no CRS, sendo até cinquenta vezes mais rápido e sessenta vezes mais barato. Esta análise reafirma que é possível economizar tanto tempo quanto dinheiro usando GPUs na nuvem, e conclui que quanto maior for o dado e quanto mais computacionalmente intenso for o operador, maiores serão os ganhos de desempenho observados e economias.Palavras-chave: computação em nuvem, GPU, processamento sísmico.

Published: April 2021

Patients with maxillectomy face problems with speech, swallowing, chewing and appearance. These defects are prosthetically rehabilitated with obturators that prevent oronasal communication, restoring function and social reintegration.
An obturator must be light-weight, tight, easy to make and low cost. This article describes a simplified technique for fabrication of an acrylic hollow bulb obturator in two pieces using single flask. The prosthesis is made entirely of heat cure acrylic resin. The two parts of the obturator are sealed with the self-curing resin.
5. Attitudes on Investment in Descendants: Products of Evolution?
Authors: Myran Aaron 
Published: April 2021

This study aims to examine intergenerational equity (concern for future generations) from a human evolutionary ecology perspective. The extent to which males and females differ in their concern about the welfare of future generations can be interpreted as a product of natural selection. We hypothesized that reproductive advantage is conferred upon males by discounting future generations and focusing on their immediate well being. Given that males potentially have many children, and do not invest the same resources in raising children, it is to their reproductive advantage to focus on the present and their own wellbeing, so that they can continue to reproduce. It is hypothesized that reproductive advantage would be conferred upon females who are concerned about future generations. Females potentially have fewer children and invest more in raising children. It is therefore more to their reproductive advantage to ensure that children survive to adulthood. Using a between‐subjects design online survey, emailed to individuals in the Queen's Community (Students, Staff, Faculty, and Alumni), we asked participants to indicate what proportion of available money ($10, 000 they received by chance) they would allocate to mitigating a hypothetical food crisis (collectivist option) versus to three “individualist” options. Participants were randomly assigned to hypothetical scenarios where the food crisis affected: the participant's generation, their children's generation, their grandchildren's generation, or their great‐ grandchildren's generation. In all four scenarios, we found that males invested significantly less in mitigating the food crisis than females. Additionally, we found that neither males nor females differed significantly between scenarios in the amount they invested in mitigating the food crisis.
6. Mental State Decoding in Dysphoric Individuals: The Role of Motivation
Authors: Sinclair Brooke 
Published: April 2021

Depression is associated with pervasive impairments in social and interpersonal functioning. Research demonstrates that individuals with depression have difficulty interacting with peers and show lower levels of social activity than do nondepressed individuals (Levendosky, Okun, & Parker, 1995). In addition, depressed individuals report that their social interactions are less supportive and less rewarding than those of non‐depressed individuals (Nezlek, Hamptom, & Shean, 2000). This reduced social competence may cause depressed individuals to disengage from social interaction, which may in turn exacerbate their state of depression (Rippere, 1980). It is thus important to understand and identify the mechanisms beneath these deficits. Researchers commonly use the theory of mind framework to understand impaired social functioning in clinical conditions. Theory of mind refers to the ability to make judgments about others’ mental states to understand and predict their social behaviour. Research has found a relationship between theory of mind and dysphoria (i.e., elevated scores on a measure of depression symptoms, but not necessarily a diagnosis of clinical depression). Specifically, dysphoric individuals demonstrate enhanced mental state judgments (Harkness, Sabbagh, Jacobson, Chowdrey, & Chen, 2005). My research investigates social motivation as an underlying mechanism for dysphoric individuals’ enhanced decoding ability. A sample of undergraduates will participate in a theory of mind decoding task following social, monetary or no motivation. I hypothesize that dysphoric individuals will make significantly more accurate judgments than non‐dysphoric individuals. Further, I predict that social motivation will enhance non‐dysphoric individuals’ sensitivity to others’ mental states.
"PEASANTRY IS OUR HOPE AND STRENGTH": THE AGRARIAN DISCOURSE OF PRE-REVOLUTIONARY JOURNALISM OF M. HRUSHEVSKY
Authors: Telvak Viktoria , Kornovenko Serhii 
Published: April 2021

Summary. The purpose of the research is to comprehensively analyse the agrarian discourse of pre-revolutionary journalism of M. Hrushevsky. The methodological basis is an interdisciplinary approach with particular emphasis on the structural-functional systematic analysis of historiographical facts and the method of critical analysis of documentary material. The scientific novelty of the article lies in the attempt to comprehensively analyse M. Hrushevsky’s appeal to peasantry in his journalism of the late XIX – early XX centuries. Conclusions. The conducted historiographical analysis has shown that the pre-revolutionary journalism of M. Hrushevsky focused on peasants and the most important problems of their lives. In his various texts, the scholar reveals himself as an insightful observer of all aspects of peasant life on both sides of Zbruch. This comprehensive analysis provided Hrushevsky with arguments for numerous socio-cultural initiatives (Ukrainization of the public school, agrarian reform, the launch of projects aimed at the peasant audience, etc.) designed break the vicious circle of patriarchal traditions and feudal prohibitions and guide peasants towards modernization. At the same time, the trusting and serious tone of the historian in his appeals to his reader, his encouragement take destiny into their hands make Hrushevsky’s writing style so distinct. Due to such peasant-oriented rhetoric, M. Hrushevsky’s ideas had a significant impact on the Ukrainians of his time and largely became the basis for agricultural legislation during the War for independence.

Summary. The purpose of the article is to publish and analyze an underground document from the Lapayev Archive "Report on Life at the State Teachers’ Institute in Drohobych" (1949) as a source for the history of everyday life at the Drohobych Teachers’ Institute in particular and in Western Ukraine in general. Research methodology – the principles of science, objectivity, historicism, methods of external and internal criticism of sources. The scientific novelty is that for the first time a hitherto unknown document on everyday life at the Drohobych Teachers’ Institute (1949) is introduced into scientific circulation and its analysis is carried out. Conclusions. Thus, the published document ("Report on Life at the State Teachers’ Institute in Drohobych") is an important source for studying the everyday history not only of the Drohobych Institute (1948–1949), but also of the whole of Western Ukraine. It is stored in the Archives of the Center for the Study of the Liberation Movement (Fund 63, Volume 4, Sheet 1‒4). The author of the document is the propaganda officer of the Drohobych OUN supra-district leadership J. Luzhetsky-"Stone" (who in this document signed one of the pseudonyms "5-TR"). The document itself was prepared on August 9, 1949. Although it includes information reports for 1948 – the first half of 1949. Note that the published documents are an important source for a comprehensive study of everyday life Drohobych Institute (1948–1949) in particular and postwar life residents of the Western Ukraine in general. The vocabulary, author’s and editorial features of the sources are preserved in the publication as much as possible. Own and geographical names are given without changes.

Authors: Muzychko Oleksandr 
Published: April 2021

Summary. The purpose of this article is to study the participation of Moszynski family in the social and cultural processes of Europe and the United States in the ХХ century. The methodological basis was chosen taking into account the objective and specificity of the object and subject of study. The basis is the system of methods of scientific of scientific knowledge: formal logic (analysis, synthesis, deduction, induction, analogy, abstraction) in order to clarify the content of the studied issues; theoretical – for the analysis of scientific literature; method of system analysis – to generalize the features of the historiographical and memorial situation. Problem-chronological, empirical, comparative and source methods are also used. The scientific approach of the publication is the formulation of new provisions on the peculiarities of the participation of Moshynski family in the social and cultural processes of Europe and the United States in the ХХ century. Conclusions. The Moshynsky family embodies the phenomenon of preserving the Ukrainian mentality and culture outside the homeland. Art studios became a nourishing source for the family members, the content and meaning of which was to combine modern art trends with traditional, folk, and Ukrainian ones. All members of the family demonstrated an example of a successful combination of the realization of artistic inspiration with public activities aimed at protecting the national interests of Ukrainians. Of great importance was the family’s experience in defending conservative, religious, and values. The phenomenon of the Moshynski family was already realized by contemporaries, who considered it as an ideal model for Ukrainian families in the diaspora. Prospects for further research are to expand the source base, recourse to oral sources, family archives.
