Three Levels of Marketing: Random, Routine, and Reflective
Authors: Perry James F.
Published: June 2020

In the past, scarce resources have led us sort ourselves as if we were many kinds of beings, mostly unreflective, instead of one. Now, our very survival depends on classifying all people as human and reflective. This maturing change is already happening because high-tech weapons are not a scarce resource and the alternative is death by terrorism. The marketplace of the 21st century will profit by showing respect for consumers as reflective human beings. This paper offers a guide to the reflective level of thought and action, showing and explaining the logical and pragmatic relations between random, routine, and reflective functioning.

Gas Flame Structure and Optical Assessment of the Flame Speed and Combustion Efficiency
Authors: Trofimenko M. Yu. , Aslanov S. K. , Dragan G. S. , Smolyar V. P.
Published: June 2020

We perform the analysis of a prepared propane-butane flame structure, by using the computer processing of the radiation from the chemical reaction zone. We mark out the stoichiometric reaction along with the zones of the external oxidant inflow into the flame for different burner diameters. We suggest a method of determining the normal flame speed based on catching the moment of the complete fuel combustion in the upper part of a flame. We show a role of the external oxidant inflow in the kinetic processes within the burning zone. The absolute value of the normal component of the flame speed and its dependence on the burner diameter and on the excess oxidant ratio for a prepared propane-butane flame are determined experimentally.
Some Problems in Designing a Luminescence Converter for Si Solar Cells
Authors: Azovskyi V. A. , Yashchuk V. M. , Bulavko G. V. , Ishchenko A. A.
Published: June 2020

Aromatic polymer composites are characterized by the high absorption and luminescence excitation in the short-wave interval of the solar radiation spectrum from about 200 nm. Therefore, they can be used to enhance the spectral sensitivity of semiconductor solar cells, including silicon-based ones, at short waves. When such a composite absorbs light, there arise Frenkel excitons in it, which are responsible for the transfer of the excitation energy to molecular traps. The latter emit light in the spectral region of maximum solar cell sensitivity. The results obtained demonstrate a possibility to develop a luminescence converter on the basis of a polymeric composite, thus increasing the photocurrent generated by Si-based solar cells.
Ideal Bose Gas in Some Deformed Types of Thermodynamics. Correspondence between Deformation Parameters
Authors: Chubai O. M. , Rovenchak A. A.
Published: June 2020

Two approaches to the construction of thermodynamics in the framework of the q- and м-formalisms, which correspond to certain deformations of the algebra of the creation–annihilation operators, have been considered. By comparing the obtained results, an approximate, independent of the space dimension, correspondence was revealed between the second virial coefficients for the ideal q- and м-deformed Bose gases. The corresponding discrepancy arises only at the level of the third virial coefficient. A method for emulating the м-deformed Bose gas up to the third virial coefficient inclusive by means of the two-parametric nonadditive Polychronakos statistics is demonstrated.

Authors: Offenbacher Rachel , Rybinski Brad , Joseph Tuhina , Rahmani Nora , Boucher Thomas , Weiser Daniel A.
Published: June 2020

An 8-year-old boy with no significant past medical history presented to his pediatrician with 5 days of fever, diffuse abdominal pain, and pallor. The pediatrician referred the patient to the emergency department (ED), out of concern for possible malignancy. Initial vital signs indicated fever, tachypnea, and tachycardia. Physical examination was significant for marked abdominal distension, hepatosplenomegaly, and abdominal tenderness in the right upper and lower quadrants. Initial laboratory studies were notable for pancytopenia as well as an elevated erythrocyte sedimentation rate and C-reactive protein. Computed tomography (CT) of the abdomen and pelvis showed massive splenomegaly. The only significant history of travel was immigration from Albania 10 months before admission. The patient was admitted to a tertiary care children’s hospital and was evaluated by hematology–oncology, infectious disease, genetics, and rheumatology subspecialty teams. Our multidisciplinary panel of experts will discuss the evaluation of pancytopenia with apparent multiorgan involvement and the diagnosis and appropriate management of a rare disease.

Authors: Domond Pascale , Orri Massimiliano , Algan Yann , Findlay Leanne , Kohen Dafna , Vitaro Frank , Tremblay Richard E. , Côté Sylvana M.
Published: June 2020

OBJECTIVES:

To test associations between onset of formal child care (in infancy or as a toddler), high school graduation, and employment earnings from ages 18 to 35 years.

METHODS:

A 30-year prospective cohort follow-up study, with linkage to government administrative databases (N =3020). Exposure included formal child care, if any, by accredited caregivers in centers or residential settings at ages 6 months and 1, 1.5, 2, 3, and 4 years. A propensity score analysis was conducted to control for social selection bias.

RESULTS:

Of 2905 participants with data on child care use, 59.4% of male participants and 78.5% of female participants completed high school by age 22 to 23. Mean income at last follow-up (n = 2860) was $47 000 (Canadian dollars) (SD = 37 700) and $32 500 (SD = 26 800), respectively. Using group-based trajectory modeling, we identified 3 groups: formal child care onset in infancy (∼6 months), formal child care onset as a toddler (after 2.5 years), and never exposed. After propensity score weighting, boys with child care started in infancy had greater odds of graduating than those never exposed (odds ratio [OR] 1.39; 95% confidence interval [CI]: 1.18–1.63; P < .001). Boys attending child care had reduced odds of low income as young adults (infant onset: OR 0.60 [95% CI: 0.46–0.84; P < .001]; toddler onset: OR 0.63 [95% CI: 0.45–0.82; P < .001]). Girls’ graduation rates and incomes revealed no significant association with child care attendance.

CONCLUSIONS:

For boys, formal child care was associated with higher high school completion rates and reduced risk of adult poverty. Benefits for boys may therefore extend beyond school readiness, academic performance, and parental workforce participation.
Analysis of Primary Caesarean Section in a District Hospital
Authors: Chandel Anu Bala , Dogra Rohit
Published: June 2020

Background: Caesarean delivery is defined as an operative procedure to deliver the fetus or foetuses after the period of viaility through an incision on the adominal wall and uterine wall in an intact uterus. The World Health Organization (WHO) has identified an ideal caesarean section (CS) rate for a nation of around 10-15%1. The objective of the present study was to find the rate of primary caesarean deliveries in and its contribution to total caesarean rate and to analyze the indications of the caesarean sections.

Methods: It is a retrospective observational study conducted in the Department of Obstetrics and Gynaecology at Regional hospital,Bilaspur. A total of 90 primary caesarean deliveries were studied.

 

Results: The total deliveries during the study period were 809 and the total caesarean section rate observed was 14.96%. The caesarean section rate among primigravidae was 74.38%.  Out of the total number of primicaesarean deliveries, 92.22% were performed in emergency and 7.78% were performed electively. Among the emergency caesarean sections performed, 60.24% of patients had induced labor and 39.76% had spontaneous labor. The most common indication of caesarean section was fetal distress (43.33%) followed by failed induction(18.89%) and malpresentations (16.67%).

 

Conclusions: Caesarean audit should be performed routinely and every case should be scrutinised. Reducing the primary caesarean rate not only decreases total caesarean rate but also many long-term complications associated with previous caesarean sections like adherent placenta ,rupture uterus
Flutuação populacional de conídios de Cercospora beticola no ar e sua relação com a severidade da cercosporiose da beterraba
Authors: Marcuzzo Leandro Luiz , Nascimento Aline , Harbs Sheila Chaiana
Published: June 2020

RESUMO Em experimento de campo nos anos de 2016 e 2017 quantificou-se a flutuação de conídios de Cercospora beticola e sua relação com a severidade da cercosporiose da beterraba. Sementes de beterraba da cultivar Boro foram semeadas em quatro repetições onde foram avaliadas 80 plantas. Os conídios foram coletados através de um coletor de esporos tipo “cata-vento”, contendo uma lâmina de microscópio untada com vaselina, a qual era quantificada semanalmente com auxílio de microscópio. A severidade da doença foi analisada através de escala diagramática para avaliação da porcentagem de área foliar afetada pela doença. O número de conídios e a severidade da cercosporiose da beterraba foram submetidos ao cálculo do coeficiente de correlação linear de Pearson (r). Nos anos de 2016 e 2017 a coleta de conídios ocorreu concomitante à constatação da doença, provavelmente devido haver inóculo no ar. A correlação entre as variáveis flutuações de conídios e a severidade da doença foi significativa, com r=0,762 e r=0,768 para os anos de 2016 e 2017 respectivamente. A severidade da doença em beterraba é influenciada pela presença dos conídios coletados do ar.

Published: June 2020

RESUMO Com objetivo de estudar a epidemiologia da queima das pontas das folhas da cebola causada por Botrytis squamosa na região do alto vale do Itajaí/SC, um ensaio foi conduzido com plantas naturalmente infectadas, nas safras 2017 e 2018. A cada sete dias e, durante 10 semanas, foi quantificada a população de conídios no ar, registrada as condições ambientais e avaliada a severidade nas plantas. Observou-se, que mesmo com ambiente favorável à doença, seu início ocorreu cinco semanas após a semeadura. Constatou-se que a epidemia iniciou uma semana depois da primeira detecção do inóculo no ar em 2018. O progresso da doença foi representado pelo modelo de Gompertz y=0,51830*(exp(-5,95660*exp(-0,47392*x))). A produção da biomassa fresca de mudas foi de 1,68 e 2,8 gramas por planta nos respectivos anos de avaliação. Este estudo epidemiológico pode fornecer informações do momento do início da epidemia e será útil na validação de um sistema de previsão da queima das pontas das folhas da cebola.
Inheritance of soybean resistance to Corynespora cassiicola
Authors: Soares Rafael Moreira , Arias Carlos Alberto Arrabal
Published: June 2020

ABSTRACT The incidence of target spot, caused by Corynespora cassiicola, has gained increasing importance among the main soybean diseases in Brazil, and using susceptible cultivars can cause yield losses. Different susceptibility/resistance levels have been observed among cultivars in commercial crops but the genetics of the resistance to this pathogen is still unknown. To study the inheritance of soybean resistance to C. cassiicola, crosses were developed between cultivars including one cultivar resistant to target spot, BRS 316RR, one moderately resistant cultivar, BRS 184, and one susceptible cultivar BMX Potência RR. Parental generations, as well as F2 and F2:3 derived from their crosses, were evaluated as to severity and lesion size after inoculation with the pathogen. Quantitative analysis was applied to the data, and genetic models were adjusted for means and variances. Predominance of additive genetic effects controlling soybean resistance to C. cassiicola is suggested for the different crosses. The genetic models adjusted for the means detected an additive genetic effect more frequently. The additive variance D was detected only for the trait lesion size and had low heritability, indicating high environmental effect influencing the reaction. Based on mean and variance genetic models, further genetic gains are expected in the cross BRS 316RR x BMX Potência RR. The effect of genetic dominance was not important. The presence of significant epistasis in crosses between susceptible cultivars indicates the existence of at least two genes affecting resistance and that are interacting. The normal continuous distribution of the frequency of the number of individuals in different classes of resistance indicates that the resistance to C. cassiicola is quantitatively inherited and there is predominance of an additive genetic effect and low heritability.
Diferencial de desempenho de alunos das escolas militares: o caso das escolas públicas do Ceará
Authors: Benevides Alesandra de Araújo , Soares Ricardo Brito
Published: June 2020

Resumo O diferencial de desempenho entre estudantes de escolas militares e civis não pode ser atribuído somente ao efeito escola, uma vez que fatores como características familiares, acúmulo de conhecimento e o próprio processo de seleção estabelecido por escolas militares podem gerar um viés na performance. Este trabalho investiga se ainda persiste um efeito escola militar em modelos empíricos de proficiência a la Hanushek (2016), uma vez que esses fatores são controlados. Utilizou-se uma base de dados administrativos longitudinal para escolas públicas do Ceará, acompanhando alunos no 5º e no 9º ano, os quais foram selecionados pelo método de pareamento CEM (Coarsened Exact Matching) com relação ao desempenho no ano base. Verificou-se que a falta de controle para o viés de seleção e para desempenhos passados majora o efeito escola militar em uma vez e meia nos modelos tradicionais. Entretanto, mesmo controlando esses fatores, o efeito escola militar ainda é significante.
Efeito-vizinhança e o desempenho escolar: o caso dos estudantes da rede pública de ensino da Cidade do Recife
Authors: Araujo Julia Rocha , Silveira Neto Raul da Mota
Published: June 2020

Resumo Este artigo tem como objetivo analisar a influência da vizinhança sobre o desempenho escolar dos alunos da rede pública de ensino do Recife. Especificamente, o trabalho investiga empiricamente a existência de uma relação entre o desempenho do aluno e as características de sua vizinhança e os mecanismos pelos quais atua essa influência. Para tanto, utiliza-se a base de dados da Fundaj (2013) para construir, de forma pioneira no Brasil, as variáveis de vizinhança dos alunos da cidade considerando pequenas escalas geográficas. Os resultados dos exercícios econométricos indicam que os alunos residentes em uma vizinhança mais privilegiada tendem a apresentar, em média, melhor desempenho em matemática. Na análise que considera a composição dos pares de vizinhança, os resultados sugerem que a proporção de repetentes influenciaria o desempenho de matemática.
Intermediate services’ impact on capital goods production
Authors: Giovanini Adilson , Pereira Wallace Marcelino , Saath Kleverton Clóvis de Oliveira
Published: June 2020

Abstract: The literature on intermediate services has shown that this sector contributes to industrial competitiveness and productivity rises. The production frontier is used to determine whether intermediate services contributed to the growth of capital goods production in the period between 1995 and 2009. The results found corroborate the hypothesis that the greater use of inputs from the sector results in an increase in the capital goods production in developed countries and indicate that this relationship is much weaker for developing countries. The growth of the capital goods sector’s productivity depends on the emergence of a growing symbiotic relationship between intermediate services and new communication technologies. The presence of these services helps to explain the greater dynamism of the capital goods sector in developed countries.

Published: June 2020

Resumo Este artigo analisa se os estados brasileiros constituem uma Área Monetária Ótima ao examinar a existência de assimetrias nas respostas estaduais aos choques na política monetária e no câmbio, além de comparar a resposta estadual aos choques comuns e idiossincráticos. Para tanto, utiliza-se a metodologia inicialmente desenvolvida por Lima et al. (2018) para estimar modelos de Vetores Autorregressivos Aumentados por Fatores Dinâmicos (FAVAR), que incorpora o amostrador de Gibbs proposto por Waggoner e Zha (2003) para identificar Vetores Autorregressivos Estruturais (SVAR) através de restrições de sinais nas funções impulso-resposta ao amostrador de Gibbs, desenvolvido por Bernanke e Boivin (2003) para estimar modelos FAVAR. O modelo permite identificar assimetrias nas respostas das taxas de crescimento do produto e dos preços dos estados brasileiros aos choques na política monetária e no câmbio, além de estimar a importância relativa das respostas das taxas de crescimento econômico estaduais aos choques comuns e específicos.

Abstract: How can the complexity of the school crisis be faced? How can a static and closed model of knowledge be overcome in favour of openness, flexibility, plurality and change? How can we not offer simple solutions to a complex problem? In this article, we present some paths forward in the search of answers to these questions. The first proposal is for us to overcome the dualistic relationship between subject and environment, considering both as part of a single ecosystem, based on the symbiosis between respective elements. The second proposal is for us to take our gaze away from the ecosystem through an ecological approach, for us to perceive the immersion of the subject in the respective environment. Finally, we propose deepening the existing relationships in the ecosystem, to understand its interconnected structure. In conclusion, we tackle the concept of situated teaching, as a practical application of the presented reflections.

ABSTRACT Objective This investigation evaluated the use of food labels and consumers’ perception of the reliability of food labels nutritional information. Methods This is a transversal exploratory quantitative investigation, carried out in Curitiba, Brazil. A total of 536 students from a public institution participated in the survey answering a structured questionnaire. Descriptive analyses, Chi-Square test and Fisher’s exact test were performed considering a significance level of 5%. Results The participants’ mean age was 21.11±2.83 years, and 59.3% were female. It was noticed that 41.6% of consumers used the nutritional information sometimes and 14.7% always, mainly because they liked to know what they were buying and consuming (35.8%). Lack of patience (29.5%) and concern about the composition of the food purchased (34.2%) were the main reasons for not using the information provided. The most commonly used nutrition claim was “trans fat-free” (42.5%) and the type of food in which nutrition labeling was used most was milk and dairy products (42.0%). Frequent use of nutritional information was higher among women (p<0.01) and among those who practice physical activity (p=0.04). Many individuals relied on food labels nutritional information (61.9%), but out of these, 43.6% did not use that information at the time of purchase. There was no difference between respondents’ confidence in the information, sociodemographic and health data. Conclusion Many people still do not use the label nutrition information. Efforts should be made to change this scenario. Changes in nutrition labeling can help modify this situation, with the use of clearer label information, more easily understood, that does not raise any doubts in the consumers’ mind.
A contemporary and innovative care model for older adults
Authors: Veras Renato
Published: June 2020

Abstract The population aging that has arisen from Brazil’s new demographic and epidemiological reality, a relatively recent phenomenon, requires innovative and efficient responses. This article presents a care model for the older population with the most contemporary comprehensive care and an excellent cost-benefit ratio. The proposal is aimed at health promotion, disease prevention and the coordination of care, with an emphasis on low complexity instances of care. The integrated models seek to solve the problem of fragmented and poorly coordinated care in current health systems. For this reason, we propose a low complexity care unit, an epidemiological assessment, a social center and a team formed by a pair of medical and nursing professionals, with the support of gerontologists. There will also be medical records that cover clinical and social aspects, as well as a quality information system - all involving advanced technology, accessible by doctors and clients at any time via cloud technology and a cell phone app. The more the healthcare professional knows their patient’s history, the better the results. The concepts and structure that underlie this model, which aims to reduce waste, offering greater quality at reduced cost, are set out. It is our contribution to benefit - be it in the public or supplementary sector - health care aimed at the fastest growing age group in Brazil.

ABSTRACT Objective: To evaluate the safety attitudes of the nursing staff and their relationship with staff adequacy and material resources, time of experience and intention to leave the job. Method: A descriptive and cross-sectional study in a teaching hospital, sampled by convenience, with the application of the Safety Attitudes Questionnaire, collected from January to April 2016. Results: 262 professionals participated, of whom 98 were nurses and 164 technicians. They reported a positive safety attitude for job satisfaction. The adequacy of staff and material resources positively influenced safety attitudes. There was a negative correlation between time of experience and perception of management, safety climate, working conditions and safe behaviors and, between the intention to leave the job and the teamwork climate, job satisfaction, and safe behaviors. Conclusion: The negative perception of safety attitudes was related to the time of experience and to the intention to leave the job.

ABSTRACT Objectives: To analyze the distribution and spatial autocorrelation of the hospitalization rates for cardiovascular diseases in adults, and to verify the correlation with socioeconomic and health factors in Brazil. Methods: An ecological study of hospitalization rates for cardiovascular diseases in adults from 2005 to 2016. Spatial dependence was analyzed by the Moran Global and Local autocorrelation coefficients. The correlation between hospitalization rates and socioeconomic and health variables was calculated using the Spearman’s correlation coefficient. Results: The highest hospitalization rates were observed in the states of Santa Catarina, Paraná, São Paulo, and Mato Grosso, with high-high autocorrelation clusters for ischemic heart disease. The hospitalizations for cardiovascular diseases were strongly correlated with low schooling, alcohol consumption, and diagnosis of hypertension. Conclusion: The high rates of hospitalization in the states mentioned, linked to socioeconomic and health factors, suggest public policies focused on the theme.

Published: June 2020

This paper presents the voyage of an innovative design and development and performance study of the multi-condition acceptability and flexible operation of a tar-free municipal solid waste (MSW)–refuse derived fuel gasifier. The innovation of the technology and its development are highly emphasised for converting waste into energy through gasification. The designed and fabricated gasifier (100 kg/h capacity) is a downdraft gasifier that is square in shape and operates slightly above atmospheric pressure to generate tar-free producer gas. The design operates with pellets and fluffy MSW. The generated producer gas was tested for both thermal applications. This designed gasifier can be scaled up and implemented to suit the requirements of industrial energy demand, which has wide-ranging applications. For optimum performance, a 25 kg amount of char is needed to gasify MSW completely. The energy output from the mass and energy balance is 92.5% optimal for effective gas generation. Energy generation from the designed gasifier and process optimisation for thermal energy from gas with enhanced efficiency abets in drastically reducing the cost of factory’s energy consumption. This also helps achieve reduced environmental emissions with good returns on investments.

Published: June 2020

Introduction:This article is a product of the research “Health and Psychosocial Well-Being in Organizations: Effectiveness of positive interventions to improve working life from Positive Psychology” carried out during 2016 and 2018 at Universitat Jaume I in Spain. Problem:The changing conditions of the ecosystems, in which the organizations are immersed, correspond to the growing relationships between the different actors within and outside the organizational context. This constitutes a complex system, difficult to understand in the business context, making it difficult to act upon its structure for the generation of competitive advantages in the market, where the psycho-social construct of healthy organization is established as an emergency. Objective:To offer an alternative solution to the theoretical divergence of building positive organizations. Methodology:Development of a healthy organizational model, cellular type, based on a set of variables in which the GPTW and HERO models coincide, with the implementation of this structure, through a transit methodology that makes the objective of being the best place to work tangible. Conclusion:Establishing a healthy organizational model of cellular structure allows for the perception of the organizational context through traceable and flexible variables that respond to internal and external labor changes. Originality:The advances in relation to the psycho-social construct of the health organizations are limited due to multiple heterogeneous models, however, a homogeneous model is traced for the first time in this work, based on others that have been implemented in different entities. Limitations:Establish an evaluation of the model to accurately adjust the relationship between variables.

Introduction:This article is the product of the research “Simulation level performance analysis of optical amplifiers for a DWDM XGS-PON network environment”, supported by the Research Group in New Technologies in Telecommunications (GNTT) of the University of Cauca during 2019.

Problem:For the implementation of XGS-PON optical network architectures, amplification processes are required. These generate power penalties that lead to the presence of non-linear phenomena, significantly degrading network performance.

Objective:To analyze the performance of a DWDM / XGS-PON network architecture, respecting the power penalties generated by implementing different types of optical amplifiers in different amplification modes.

Methodology:Compilation of relevant bibliography on long-range network architectures with symmetric speeds of 10 Gbps.

Results:Not working in the ideal region of amplification affects the performance of a DWDM XGS-PON network, generating a migration of a linear to non-linear propagation regime, due to the presence of power penalties such as FWM.

Conclusion:With this investigation it is possible to determine which amplifier should be used according to the needs of the optical network, evaluating the different alternatives available in the market, depending on the cost, configuration and performance of the system.

Originality:A new research is carried out for the performance of DWDM XGS-PON state-of-the-art network architectures, regarding the incidence of non-linear propagation phenomena.

Restrictions:In some cases, the simulation tool requires a high consumption of machine resources and processing time.
