Abordagem histórica e artística do uso das cores Azul e Rosa como pedagogias de gênero
Authors: Baliscei João Paulo
Published: August 2020

Historicamente, como as cores têm sido utilizadas como pedagogias de gênero e sexualidade? Esse artigo de cunho bibliográfico e analítico tem o objetivo de investigar, a partir de aspectos históricos e artísticos, como as cores azul e rosa têm desempenhados pedagogias de gênero e sexualidade em sociedades ocidentais. Adotaram-se os Estudos Culturais e Estudos de Gênero, aproximando-os de produções artísticas em que o azul e o rosa foram associados a gêneros específicos. Verificaram-se indícios de que, antes do século XX, no ocidente, fora comum identificar meninos de rosa e meninas de azul. Posterior ao século XX, porém, as identificações cromáticas passaram a ser inversas, isto é, o azul foi associado às masculinidades e o rosa, às feminilidades.
Maternal body mass index, gestational weight gain and birth outcome among puerperal women in the Tamale metropolis of Ghana
Authors: Puotege Sheila k , Seidu Mariama , Kangkpi Louisa , Yussif Abdul Rauf Mariam , Yakong Vida Nyagre , Mumuni Abdul Nashirudeen
Published: August 2020

Background/Aims

Maternal, fetal and child health are of key public health concerns, globally. Both pregestational body mass index and gestational weight gain are critical players in maternal health, fetal development and delivery outcome. This study investigated the association between maternal assumed pregestational body mass index, gestational weight gain and outcomes of deliveries among puerperal mothers in the Tamale metropolis of Ghana.

Methods

A cross-sectional randomised descriptive study was conducted at the postnatal and neonatal intensive care units of the state-owned hospitals in the Tamale metropolis. The mothers' body mass index at their first antenatal care clinic was assumed to be their pregestational body mass index. Maternal gestational weight gain was calculated using the last gestational weight before onset of labour. Participants also responded to structured questionnaires with questions on their sociodemographic characteristics and intra-pregnancy behaviours. Additionally, information on their obstetric and gynaecological history, and their delivery outcome were collected. Data were analysed using descriptive statistics and chi-squared tests, with significance set at P<0.05.

Results

A total of 450 puerperal mothers were involved in this study with a mean age of 29±1.79 years. Maternal body mass indexes at first antenatal clinic visit were predominantly typical (41.8%) or overweight (42.0%). At delivery, 46.4% of mothers had typical gestational weight gain, while the majority (53.6%, P=0.0387) had anomalous gestational weight gain. Strikingly, 72.9% of mothers who had a healthy body mass index at the first antenatal clinic visit experienced anomalous gestational weight gain. Caesarean section delivery was significantly prevalent among pregnant women who had typical gestational weight gain (P=0.0014). Also, episiotomy was significantly linked to typical gestational weight gain (P=0.0448), but not mothers who were overweight before conception (P=0.2692), irrespective of their gestational weight status.

Conclusions

Anomalous gestational weight gain is high among puerperal mothers in the Tamale metropolis, and suggests contributory roles in adverse maternal and fetal health. A comprehensive gestational weight management education programme for women in the metropolis could help curb the burden of anomalous gestational weight gain.
What is school readiness? A qualitative exploration of parental perceptions in England
Authors: Davies Nathan , Cooper Rosie , Bains Manpreet
Published: August 2020

School readiness is a strong predictor of educational attainment and future health, but its meaning to parents is uncertain. This study aimed to generate an understanding of how parents conceptualise school readiness, and the forms of support they would find most acceptable and effective. Semi-structured interviews were undertaken with 17 parents and were analysed thematically. Parents appeared conflicted in their beliefs about the most important school readiness factors (physical, social and emotional health) and those they perceived schools to prioritise (numeracy and literacy). Parents reported orienting children towards developing cognitive skills because they believed schools favoured these over socio-emotional aspects of school readiness. Parents valued health visitors' input in developing understanding of school readiness. Parental understanding of school readiness could be better supported, along with information on how best to prepare children. Health visitors could play a pivotal role in school readiness and have opportunities to educate and empower parents of young children.

Published: August 2020

We report a schlieren-style stroboscopic phase-contrast field-amplitude imaging of two-dimensional acoustic whispering gallery modes in a circular shell cavity immersed in liquid. A schlieren signal is combined with a presplit reference beam to enable nonscan field-amplitude imaging. Excitation mechanisms of standing and traveling eigenmodes, respectively, are analyzed with acoustic ray simulations presented in a Poincaré surface of sections. The time evolutions for both standing and traveling eigenmodes are reconstructed using the stroboscopic capability.
Evaluating a neural network and a convolutional neural network for predicting soliton properties in a quantum noise environment
Authors: Acuna Herrera Rodrigo
Published: August 2020

With its applications in science and engineering, supercontinuum (SC) generation is a phenomenon widely studied in nonlinear fiber optics. The SC spectral properties are not difficult to measure, except those related to time. Fortunately, machine learning can help predict the time behavior of various nonlinear optics phenomena using spectral characteristics. In this study, supervised machine learning tools are used to evaluate the prediction accuracy of the soliton properties in a noisy environment. A neural network (NN) and a convolutional neural network (CNN) are implemented to assess the performance of these techniques in relation to predicting soliton properties when noise is included in a laser that pumps a nonlinear fiber optics. We conclude that the CNN shows better performance compared with NN, as it involves more data with the same quantity of simulations conducted in both cases, whereas NN can better predict the target in the absence of noise.

Spectral DiffuserCam: lensless snapshot hyperspectral imaging with a spectral filter array
Authors: Monakhova Kristina , Yanny Kyrollos , Aggarwal Neerja , Waller Laura
Published: August 2020

Hyperspectral imaging is useful for applications ranging from medical
diagnostics to agricultural crop monitoring; however, traditional
scanning hyperspectral imagers are prohibitively slow and expensive
for widespread adoption. Snapshot techniques exist but are often
confined to bulky benchtop setups or have low spatio-spectral
resolution. In this paper, we propose a novel, compact, and
inexpensive computational camera for snapshot hyperspectral imaging.
Our system consists of a tiled spectral filter array placed directly
on the image sensor and a diffuser placed close to the sensor. Each
point in the world maps to a unique pseudorandom pattern on the
spectral filter array, which encodes multiplexed spatio-spectral
information. By solving a sparsity-constrained inverse problem, we
recover the hyperspectral volume with sub-super-pixel resolution. Our
hyperspectral imaging framework is flexible and can be designed with
contiguous or non-contiguous spectral filters that can be chosen for a
given application. We provide theory for system design, demonstrate a
prototype device, and present experimental results with high
spatio-spectral resolution.

Published: August 2020

This work reported the n-alkanes contents in a 10 m peat core collected at Timbarap, Sarawak. Different biomarker proxies were used to understand the predominance of sources present in the tropical peatland of Borneo. The total concentrations of n-alkanes in selected depths of Timbarap peat core ranged between 0.01 and 12.60 μg/g with an average of 1.58 μg/g. The presence of strong odd-to-even predominance from higher molecular weight n-alkanes homologues with high values of carbon preference index (CPI) provide clear evidences of the terrestrial plant wax assemblages. Increment of low-molecular-weight n-alkanes provide an indicator of biogenic-aquatic organic materials. The ratios of isoprenoids (pristane and phytane) have shown that the peat core was under anaerobic and reducingdepositional conditions, which could result the predominance source that alternated between aquatic-biogenic and terrestrial-derived materials.

Published: August 2020

simple, specific, linear, accurate and precise reverse phase chiral HPLC method was developed for the separation of efavirenz enantiomers by using the Lux Amylose-2 column containing amylose tris(5-chloro-2-methyl phenyl carbamate) as a stationary phase. The mobile phase consists of 0.1 % formic acid in water and acetonitrile (55:45, v/v). The flow rate was kept at 1.0 mL/min and the detection wavelength used 252 nm and the column temperature was set at 25 ºC. The limit of detection was 0.01 mg/mL and the limit of quantification was 0.04 mg/mL. The linearity calibration curve of (R)-enantiomer was shown well from the range of 0.04 mg/mL to 0.4 mg/mL. The values of the correlation coefficient were 0.999 and 0.999 for (R)-enantiomer and (S)-efavirenz, respectively. The percentage recoveries of (R)-enantiomer from efavirenz drug substance were ranged from 93.5% to 107.5%. The results demonstrated that developed RP-chiral HPLC method was simple, precise, robust and applicable for the estimation of (R)-enantiomer in efavirenz API. This method was validated in as per ICH Q2 (R1) and USP validation of compendial methods <1225>.

Published: August 2020

Copper nanoparticles (CuNPs) have captivated amazing and renewable interest in recent years due to their fascinating features. In present
investigation, CuNPs were produced by reducing copper sulphate with ascorbic acid (vitamin C) in aqueous medium without inert gas
insulation at low temperature (80 ºC). In present synthetic procedure, a native vitamin C was applied as insulating agent to prevent
oxidation of nascent CuNPs during the process and in storage. Triton X-100 was added that worked both as a size controller and as a
capping agent. The CuNPs were characterized by UV-visible and FT-IR spectroscopies, powder X-ray diffraction (PXRD) and scanning
electron microscopy-energy dispersive spectroscopy (SEM-EDX). Optical properties of Cu nanoparticles were explored using UV-vis
spectroscopy. FT IR was employed to uncover the bonding between copper nanoparticles and Triton X-100. The CuNPs were discerned
by PXRD and SEM-EDX Techniques. From the major diffraction peaks, the average particle size is determined using Debye-Scherer
equation and it is found to be about 15 nm. It is hoped that the present results would pave a way for developing plans for the production
of nascent CuNPs in the absence of inert gas insulation.

Published: August 2020

The photodegradation of high density polyethylene (HDPE) using CaO nanoparticles as a catalyst was carried out using 500 W lamp.
After exposure, morphology as well as thermal properties of the HDPE was investigated by scanning electron microscopy (SEM) and
differential scanning calorimetry (DSC). SEM results showed that the HDPE is more prone to crack into small fragments, which indicated
a rise in crystallinity with different amounts of catalyst i.e. CaO nanoparticles. The DSC results confirmed the remarkable influence of
photodegradation on degree of crystallinity (XC%), fusion enthalpy (ΔH J g-1) and melting temperature (Tm) of HDPE. Infrared spectrometry
(FTIR) demonstrated all functional groups of HDPE, present before and after photodegradation. Overall results showed that HDPE was
photodegraded into small fragments successfully by using CaO nanopartilces, where different functional groups such as carbonyl, esters
and vinyl were obtained during chain scission.

Published: August 2020

The ultrasonic investigation is one of the most effective and economical technique to analyze the nature of the matter. Ultrasonic techniques
provide valuable information about the physico-chemical nature of the aqueous solutions. Thus, the propagation characteristics of an
acoustical wave in solutions are used to study the nature of intermolecular interaction. In this work, the ultrasonic velocity, viscosity and
density studies were determined to study the effect of concentration and pH in the aqueous hydroxyethyl propyl cellulose (HEPC)
solutions at different temperatures (303, 313 and 323 K). From the observed values, the necessary related ultrasonic parameters are
calculated and their variations are discussed. The findings from the result say the variations in the velocity and absorption coefficient
values are only due to the conformational changes that occur in the HEPC solution.

used for medicinal purposes are Sansevieria trifasciatam which is known for cure of many diseases. However, little attention is given to
this plant in proving it medicinal worth and capability as an antioxidant agent. This study was initiated to set up a metabolite classes
profile and the potential enzymatic antioxidant of the variations of these plants. Crude extracts of S. trifasciata var. Laurentii and S.
trifasciata var. Zeylanica were prepared from their leaves, and solvent used has different polarities. Qualitative phytochemical analysis
was carried out using the extracts. Phytochemical screening suggested both of these samples contain carbohydrates in all extracts. It also
show that flavonoid was found in hexane and ethyl acetate extracts while did not observed in the methanol extracts for both samples.
However, alkaloid, phenol and tannin were positive in all of the methanol extracts except for hexane and ethyl acetate extracts. For the
biological activity, all extracts were selected for the determination of enzymatic antioxidant activity test using catalase (CAT) assay and
guaiacol peroxidase (gPOD) assay using UV-VIS spectrophotometer. Based on the results, CAT specific activity was the highest in
methanol extract of S. trifasciata var. Laurentii (3.15 ± 0.50 units/mg protein) compared to S. trifasciata var. Zeylanica (2.20 ± 0.05
units/mg protein). For gPOD specific activity, ethyl acetate extract of S. trifasciata var. Laurentii shows the highest activity which is 1.46
× 10-2 ± 0.02 units/mg protein compared to the other crude extracts.

Published: August 2020

The main purpose of this research is to develop a low-cost and novel bioadsorbent hydrogel from rice husk (PRH) and modified rice husk (MRH) by carboxymethylation and grafting for the effective removal of chromium(VI) from aqueous solutions. The characterization and physico-chemical parameters of the bioadsorbents (PRH and MRH) was also performed. It was found that -CHO, >C=O, C-OH, Si-OH and -Si-H groups widely contributed towards the adsorption of chromium(VI) into the surface of bioadsorbents. The adsorption studies had been conducted using batch experiments. The adsorption equilibrium were analyzed and described by Freundlich, Langmuir and Dubinin-Radushkevish (D-R) isotherm models. It was observed that maximum adsorption of chromium(VI) was attained at pH 2. The optimized conditions regarding the removal of Cr(VI) using PRH (65%) and MRH (78%) as bioadsorbents were at 0.5 g/L of adsorbent dose, 120 min of contact time and pH 2. The results showed that rice husk residue based hydrogel has the potential to be used as a lowcost biosorbent for the removal of Cr(VI) from wastewater.

Published: August 2020

This work reports the enhancement of humidity sensing properties of tungsten trioxide (WO3) by the formation of nanocomposite with
cuprous oxide (Cu2O). A 0.1 g of Cu2O was mixed with 0.9 g of WO3. Pellets of pure WO3 and the obtained mixture are prepared at
pressure of 250 MPa applied for 0.5 h. The pellets were then annealed at 300 ºC, 400 ºC, 500 ºC and 600 ºC. X-ray diffraction (XRD) and
scanning electron microscopy (SEM) analyzed the crystallinity and morphology of as-prepared pellets surface. Humidity sensing application
of pellets is studied in a specially designed chamber. It is observed that as relative humidity increases, there is decrease in the resistance
of the pellets. The humidity-sensing investigation (10-99%RH) showed that the nanocomposite of Cu2O with WO3 annealed at 600 ºC, is
having the best sensitivity, low hysteresis, less ageing and high reproducibility than pure WO3. It is also observed that as annealing
temperature increases from 300 to 600 ºC, sensitivity increases. The present investigation could be useful for fabrication of resistive type
humidity sensors for commercial applications.

O Programa Brasil Sorridente possui o objetivo de mitigar as desigualdades no acesso à assistência em saúde bucal a todas as faixas etárias nos diversos níveis de atenção, tendo os Centros de Especialidades Odontológicas (CEO) com a função de suprir a demanda por atendimentos especializados. Usuários que chegam às Unidades Básicas de Saúde (UBS) são referenciados aos CEO e posteriormente contra referenciados às UBS de origem, configurando a rede de referência e contra referência (RCR), situadas entre as áreas programáticas do município do Rio de Janeiro. Com o objetivo de demonstrar a aplicabilidade do instrumental teórico-metodológico da Análise de Redes Sociais (ARS), avaliou-se a possibilidade de utilização deste instrumental como suporte analítico à governança para futuras investigações da realidade. Com caráter descritivo e analítico, foram pesquisados dados de acesso livre disponíveis no portal do DataSUS. Utilizou-se o software Gephi para a construção dos gráficos da rede formada entre as UBS e CEO. Observaram-se clusters em algumas áreas programáticas, podendo estar trazendo sobrecarga nos atendimentos dos mesmos. Diante da limitação de análise sugere-se que a utilização da ARS, possa ser uma alternativa à governança em prol de programas de saúde.

Published: August 2020

O uso de agrotóxicos na prática agrícola brasileira é utilizado de maneira intensiva. Entretanto, ainda há necessidade de análises mais abrangentes utilizando banco de dados de base populacional que visem avaliar os perfis regionais. O número de trabalhadores do meio rural expostos diretamente a estes xenobióticos é expressivo, sendo ainda mais agravante quando se considera o não uso ou uso inadequado de Equipamentos de Proteção Individual (EPI’s). A exposição direta aos agrotóxicos pode causar diferentes problemas de saúde como doenças degenerativas e intoxicações agudas. No cenário brasileiro, a região Sul se destaca devido a sua amplitude agrícola e sua massiva utilização de agrotóxicos. Portanto, o objetivo deste artigo de revisão é identificar, através dos dados dispostos no DATASUS (Departamento de Informática do Sistema Único de Saúde), o número de intoxicações exógenas por agrotóxicos entre os anos de 2013 e 2017 nos estados que compõem região sul do Brasil. Para realização deste estudo de revisão foram utilizadas informações de um banco de dados secundário proveniente do DATASUS. Nos resultados, foi possível observar que os estados de Santa Catarina e Paraná obtiveram maiores prevalências de intoxicações quando comparados ao estado do Rio Grande do Sul entre os anos de 2013 e 2017. Os três estados apresentaram diferenças significativas das prevalências de cura com sequela e taxa de óbito entre homens e mulheres. As taxas de óbito apresentaram uma tendência linear no período analisado nos estados do Rio Grande do Sul e Santa Catarina. Conclui-se que há diferenças significativas no perfil de prevalências de intoxicações entre os três estados analisados e que há uma premente necessidade de políticas públicas que visem a diminuição das taxas apresentadas.

Published: August 2020

As superfícies em um ambiente hospitalar contribuem para a contaminação cruzada secundária. Tal contaminação acontece através do contato das mãos dos profissionais com a manipulação dos dispositivos ou equipamentos e as suas superfícies, que poderão estar contaminadas e acabar contaminando os pacientes. É importante ressaltar que o comportamento dos profissionais de saúde tem grande influência de maneira direta no que tange a transmissão de infecção hospitalar. O presente estudo objetivou analisar o perfil bacteriano de superfícies e equipamentos do Bloco Cirúrgico de um Hospital Universitário. Trata-se de um estudo transversal e descritivo onde foram amostradas 06 salas do Bloco Cirúrgico e analisadas as seguintes superfícies e equipamentos: braçadeira, mesa cirúrgica, monitor multiparamétrico, oxímetro, foco de luz e carrinho do anestesista. As amostras foram coletadas, utilizando-se um molde de área de 1 cm2 e swabs embebidos em solução salina.

A doença arterial coronariana (DAC) é uma das principais causas de óbitos no mundo. A cirurgia de revascularização do miocárdio (CRM) prolonga a sobrevida e reduz a mortalidade de pacientes com DAC. Inúmeros estudos comparam os resultados obtidos em CRM com e sem o suporte da circulação extracorpórea (CEC), contudo, não existe um consenso sobre a modalidade ideal para esta cirurgia. O presente estudo consiste em uma revisão da literatura em que foram incluídas publicações que abordassem os resultados da realização de revascularização do miocárdio com e sem a utilização de circulação extracorpórea. Um total de 2.175.226 pacientes foram estudados, destes, 1.594.036 realizaram o procedimento com CEC e 581.190 foram submetidos a cirurgia sem CEC. A média de internação na unidade de tratamento intensivo (UTI) nos procedimentos realizados com CEC foi de 82,44 horas e quando realizado sem CEC foi de 55,95 horas. A média da quantidade de horas que os pacientes permaneceram sob ventilação mecânica após procedimentos com CEC foi de 16,12 horas e sem CEC foi de 11,34 horas. A mortalidade total dos pacientes submetidos a CRM com CEC foi de 909 sobre 25.074 indivíduos envolvidos (3,62%). Quando o procedimento foi realizado sem CEC a mortalidade total foi de 771 pacientes de um total de 27.655 indivíduos operados (2,84%). O número médio de enxertos que os pacientes receberam durante os procedimentos cirúrgicos foi maior no grupo que realizou o procedimento com CEC. Ocorreu da mesma forma, com relação à necessidade de transfusão sanguínea. É necessário que os pacientes sejam avaliados caso a caso, pois ambos os procedimentos, com e sem CEC, possuem vantagens e desvantagens. Não se pode considerar que uma técnica seja uniformemente superior a outra neste tipo de cirurgia.
English Learners’ Identity Formation as Low and High Investors in their Learning Process
Authors: Moná Maritza Collazos , Gómez Rodríguez Luis Fernando
Published: August 2020

This article reports the fndings of a descriptive case study that analyzed how unfair social relationships established in an EFL (English as a Foreign Language) classroom inﬂuenced a group of adolescent English language learners’ academic investment and identity construction at a school in Bogotá, Colombia. Data associated with students’ social behaviors and identities were collected through feld notes, a questionnaire, and an interview. Norton’s theory of identity and investment served as the basis to analyze the data from a social perspective. Three main fndings emerged from the data: First, EFL learners identifed themselves as high investors and low investors in their learning, depending on their own opinions about the usefulness of English in their lives. Second, power relationships based on domination and oppression reduced productive investment in the classroom. Third, some high investors resisted unfair relationships of power by investing through collaborative learning. Consequently, participants created diverse English learners’ identities (dominant, submissive, resistant, and productive), which inﬂuenced their academic investment negatively or positively.

We previously reported that binding to heparan sulfate (HS) is required for the ability of the placentally secreted pregnancy-specific glycoprotein 1 (PSG1) to induce endothelial tubulogenesis. PSG1 is composed of four immunoglobulin-like domains but which domains of the protein bind to HS remains unknown. To analyze the interaction of PSG1 with HS, we generated several recombinant proteins, including the individual domains, chimeric proteins between two PSG1 domains, and mutants. Using flow cytometric and surface plasmon resonance studies, we determined that the B2 domain of PSG1 binds to HS and that the positively charged amino acids encompassed between amino acids 43–59 are required for this interaction. Furthermore, we showed that the B2 domain of PSG1 is required for the increase in the formation of tubes by endothelial cells (EC) including a human endometrial EC line and two extravillous trophoblast (EVT) cell lines and for the pro-angiogenic activity of PSG1 observed in an aortic ring assay. PSG1 enhanced the migration of ECs while it increased the expression of matrix metalloproteinase-2 in EVTs, indicating that the pro-angiogenic effect of PSG1 on these two cell types may be mediated by different mechanisms. Despite differences in amino acid sequence, we observed that all human PSGs bound to HS proteoglycans and confirmed that at least two other members of the family, PSG6 and PSG9, induce tube formation. These findings contribute to a better understanding of the pro-angiogenic activity of human PSGs and strongly suggest conservation of this function among all PSG family members.
Inverse Association of Coffee with Liver Cancer Development: An Updated Systematic Review and Meta-analysis

Published: August 2020

Background and Aims: Coffee consumption has been suggested to reduce the risk for hepatocellular carcinoma (HCC). While several studies report inverse correlation with coffee drinking, others have suggested more than 2 cups of coffee every day decrease the risk of liver cancer or HCC. However, controversy exists about the exact dose that would provide protective benefit. Therefore, we aimed to carry out a systematic review and meta-analysis of all studies that investigated the association of coffee consumption and risk of HCC and/or liver cancer. Our outcomes were the evaluation of the association of coffee with HCC or liver cancer development along with the amount of coffee needed to prevent HCC or liver cancer.

Methods: We performed a PubMed/MEDLINE/EMBASE/Ovid/Google Scholar search of original articles published in English from 1996 to June 2019, on case-control or cohort or prospective studies that associated coffee with liver cancer or HCC. We calculated the relative risk (RR) of the two conditions for coffee drinking and then stratified this into increments of one cup of coffee per day. Twenty studies were identified. The analysis was performed using random effects models from the methods of DerSimonian and Laird with inverse variance weighting. The Cochrane Q and the I 2 statistics were calculated to assess heterogeneity between studies. A p<0.10 value for chi-square test and I 2 <20% were interpreted as low-level heterogeneity. Probability of publication bias was assessed using funnel plots and with the Egger’s test.

Results: The overall RR was 0.69 (95%CI 0.56-0.85; p<0.001) with significant heterogeneity between the studies. We performed subgroup analysis over the increments of 1 cup of coffee. Higher doses of coffee consumption were associated with a significant decrease in the risks of developing HCC or liver cancer. The funnel plot did not show significant publication bias.

Conclusions: Our systematic review and meta-analysis suggests that drinking coffee provides benefits with a reduction in the risk of HCC or liver cancer. Higher doses of coffee have higher benefits in terms of risk reduction. However, further biological and epidemiological studies are required to determine the exact mechanism and to study specific subgroups such as viral hepatitis B or C related HCC.
Communication in Pediatric Oncology: A Qualitative Study
Authors: Sisk Bryan A. , Friedrich Annie , Blazin Lindsay J. , Baker Justin N. , Mack Jennifer W. , DuBois James
Published: August 2020

BACKGROUND:

When children are seriously ill, parents rely on communication with their clinicians. However, in previous research, researchers have not defined how this communication should function in pediatric oncology. We aimed to identify these communication functions from parental perspectives.

METHODS:

Semistructured interviews with 78 parents of children with cancer from 3 academic medical centers at 1 of 3 time points: treatment, survivorship, or bereavement. We analyzed interview transcripts using inductive and deductive coding.

RESULTS:

We identified 8 distinct functions of communication in pediatric oncology. Six of these functions are similar to previous findings from adult oncology: (1) building relationships, (2) exchanging information, (3) enabling family self-management, (4) making decisions, (5) managing uncertainty, and (6) responding to emotions. We also identified 2 functions not previously described in the adult literature: (7) providing validation and (8) supporting hope. Supporting hope manifested as emphasizing the positives, avoiding false hopes, demonstrating the intent to cure, and redirecting toward hope beyond survival. Validation manifested as reinforcing “good parenting” beliefs, empowering parents as partners and advocates, and validating concerns. Although all functions seemed to interact, building relationships appeared to provide a relational context in which all other interpersonal communication occurred.

CONCLUSIONS:

Parent interviews provided evidence for 8 distinct communication functions in pediatric oncology. Clinicians can use this framework to better understand and fulfill the communication needs of parents whose children have serious illness. Future work should be focused on measuring whether clinical teams are fulfilling these functions in various settings and developing interventions targeting these functions.
Pobreza multidimensional urbana en Argentina. ¿Reducción de las disparidades entre el Norte Grande Argentino y Centro-Cuyo-Sur? (2003-2016)
Authors: Ignacio-González Fernando Antonio , Santos Maria Emma
Published: August 2020

Este artículo analiza las disparidades territoriales desde el punto de vista de la pobreza entre el Norte Grande Argentino (NGA), históricamente más rezagado, y las restantes regiones del país en el periodo de 2003 a 2016. A partir de datos de la Encuesta Permanente de Hogares (EPH), se estima el índice de pobreza multidimensional (IPM) basado en el método de Alkire-Foster, en atención a las dimensiones de vivienda, servicios básicos, educación, empleo y seguridad social, e ingresos. Se encuentra que hubo una disminución de la pobreza en todas las regiones y, entre 2011 y 2016, una significativa reducción de las asimetrías regionales, que, aunque alentadora, debe relativizarse por distintas razones.
Liquidity preference in a world of endogenous money: A short-note.
Authors: Missaglia Marco , Sanchez Patricia
Published: August 2020

We argue that even in the case that banks are able to maintain the interest rate at a level that they want (the most “radical” version of the theory of endogenous money), liquidity preference continues to constitute a key element when determining the real equilibrium of the economy. In a framework of endogenous money, the Keynesian theory of liquidity preference still constitutes a theory that determines level of income. Financial markets matter, and the Kaldorian idea that liquidity preference “ceases to be of any importance” can only be defended under a set of very restrictive assumptions.

The construction industry deals with the provision of shelter and infrastructure for acontinuing growing population and urbanization, especially in developing countries, Thissector is well known as a huge consumer of natural resources; which produces a significantquantity of construction and demolition waste, Data about the situation of construction wastegeneration in Costa Rica is scarce and the objectives of the study were to develop a baselinestudy to determine quantities and composition of the waste, as well as, motivators and barriersfor achieving a more sustainable activity, This paper draws the findings of the surveyundertaken by means of questionnaires, interviews and site visits, The composition basicallyis wood, soil, piping materials, corrugated roof sheets, wires, packaging materials (paper,plastic and cardboard), cement, concrete, blocks, paints and debris, The amounts (either byvolume or by weight) of these streams are unknown since the majority of the companies don'tkeep track of these data, It is suggested a value of I 00 kg/m2 as an educated guess of theamount of construction waste produced, This high amount, compared to lower values found inliterature for developed countries, could be explained by the general lack of awareness andinformation on environmental issues as well as lack of technologies, governmentalenforcement and market incentives to improve the environmental footprint of the sector,
