Puentes entre espacios y tiempos distantes: "Cartas de Cuba" (2021) de Ruth Behar
Authors: Castilleja Diana
Published: February 2024

A fin de analizar la reconstrucción de un pasado producto del recuerdo y la imaginación, proponemos una lectura de Cartas de Cuba, de Ruth Behar. Dirigida a un público juvenil e infantil, escrita originalmente en inglés (Letters from Cuba, 2019) y posteriormente traducida al español (2021), esta novela está inspirada en la abuela materna de Behar, Esther Levin, que sería la primera de siete hermanos en viajar de Polonia a Cuba para reunirse con su padre, Abraham Levin. El rol de Esther será crucial para que su madre y sus hermanos logren salir de Polonia y reunirse en Cuba. Cartas de Cuba está construida con base en 55 cartas escritas por Esther y en ella se reconstruye una memoria permeada por la ficción que completa espacios vacíos al tiempo en que abre otros. Primeramente, abordaremos la construcción de la novela con base en epístolas, que, más allá de su función pragmática-comunicativa (Barrenechea, 1990, p. 51), facilitan un doble juego en donde el lector se convierte tanto en testigo privilegiado como en voyerista usurpador de espacios privados, ajenos. En segundo lugar, abordaremos la hibridez genérica presente en esta novela que contribuye a resaltar las ambivalencias propias al género, al explorar la tensión entre: presencia-ausencia, oralidad-escritura, privado-público, fidelidad-traición, realidad-ficción, acercamiento-alejamiento (Barrenechea, 1990, p. 56; Bouvet, 2006, p. 65). Por último, dado que las epístolas proporcionan una cohesión entre «el espacio de las relaciones vividas y el horizonte de un lazo imaginario abierto en la distancia por lo escrito» (Bouvet, 2006, p. 25), argumentamos que en Cartas de Cuba el «espacio de las relaciones vividas» se configura a través de los vínculos con la patria de origen, así como a través de la afirmación de un sentido de pertenencia.

Authors:   International College, Burapha University, Thailand, Sakulsinlapakorn Kongkidakarn
Published: February 2024

The growing wellness trend has heightened people's awareness of the importance of enhancing their quality of life, particularly in their plans to purchase wellness real estate. This study aims to investigate how wellness condominium attributes influence purchase intentions, with customer-perceived value acting as a mediator. Additionally, it explores the moderating roles of reference groups, specifically informative influence and normative influence, in the relationship between wellness condominium attributes and customer-perceived value. We conducted a questionnaire survey among 400 respondents in Bangkok, Thailand. Hierarchical regression analysis was employed to test our research hypotheses. The results indicate that a strong understanding of wellness condominium attributes positively influences the perception of wellness condominium value, which, in turn, leads to purchase intention. Furthermore, our findings reveal that both informative influence and normative influence act as positive moderators, strengthening the link between wellness condominium attributes and purchase intention. The findings offer valuable insights to real estate developers on how to effectively communicate the value of residential wellness through reference groups, enhance the sustainable development of wellness residential areas, and contribute to the overall well-being of residents, both physically and mentally.

Job crafting: el concepto
Authors: García Rubiano Mónica
Published: February 2024

El concepto de trabajo en las organizaciones ha evolucionado con el paso del tiempo y se ha visto desde diversas perspectivas, entre las cuales se encuentra la contribución al bienestar físico, mental y psicológico de los trabajadores, de tal manera que se incremente su motivación y satisfacción laboral. Sin embargo es importante resaltar que los recursos que provee la organización no necesariamente son satisfactorios para los colaboradores y en algunas ocasiones estos generan estrategias personales que les permiten desarrollar su trabajo de una manera óptima de acuerdo con sus intereses. En ese orden de ideas, el job crafting se relaciona con variables como la satisfacción, la motivación y el compromiso por parte del empleado, lo cual representa beneficios no solo para él, sino también para la organización, permitiendo que se desarrollen comportamientos innovadores de cooperación y proactividad que influyen directamente en la productividad de la organización (Maola, 2018).
La conducta contraproducente en las organizaciones: el robo
Authors: Gómez Rada Carlos Alberto
Published: February 2024

El funcionamiento de la civilización humana en la actualidad depende en gran medida de la articulación de un gran número de organizaciones públicas y privadas que se encargan de generar los productos y servicios que permiten satisfacer las múltiples necesidades humanas, pero también, resulta cierto lo contrario; esto es, la operatividad de un sistema organizacional no es posible sin el aporte significativo de los seres humanos que la integran. Sobre este particular, Molina-Sabando et al. (2016) señalan que una gestión organizacional exitosa depende de que haya empleados que estén motivados, que sean creativos y que tengan sentido de pertenencia hacia la organización, lo que traerá como consecuencia trabajadores más productivos, y esto se traducirá, a su vez, en una ventaja competitiva para dicha empresa. De acuerdo con lo anterior, se espera que los empleados se comporten en función de los objetivos de la empresa y aunque en la mayor parte de los casos esto es lo que ocurre, hay ocasiones en que algunos trabajadores pueden presentar un comportamiento que va en contravía de estos intereses. Esto coincide con lo que plantea Twalo (2018), quien afirma que en el mercado laboral hay empleados que cumplen responsablemente con todos sus deberes, mientras que hay otros que conculcan las normas de una compañía e incluso se involucran en prácticas ilícitas. Es debido a estas situaciones que ha surgido hace poco una línea de investigación que estudia este tipo de comportamientos negativos que en la literatura científica se tipifican a través de varios conceptos como conductas contraproducentes, conductas desviantes y conductas antiéticas (Robbinson & Bennet, 1995; Rotundo & Sackket, 2002; Sackket & Devore, 2001, citados en Omar et al., 2012). En concordancia con lo anterior, en las siguientes líneas se abordará la definición de estos constructos, el impacto que genera para las organizaciones, sus causas, su forma de evaluación y diagnóstico, y, finalmente, las estrategias que se pueden usar para su abordaje, haciendo especial énfasis en la conducta de robo.

La evolución de la economía del conocimiento cada vez, y de manera más rápida, desafía a las organizaciones al avance tecnológico y todo lo que este conlleva en términos de la mejora de los procesos productivos y la generación de valor, por lo que exige incorporar procesos de capacitación, formación y desarrollo del trabajador. Es así como el capital humano puede convertirse en una medida del valor económico de las habilidades, capacidades y competencias, estas últimas entendidas como un conjunto de recursos disponibles que tiene una persona para resolver problemas y evidenciar un desempeño superior en el trabajo; adicionalmente, esta medida está fundamentada en el grado de contribución que realiza el trabajador. En otras palabras, hace referencia a los conocimientos que adquiere un trabajador por medio de la formación y experiencia y el entrenamiento de sus habilidades en una posición específica dentro de la organización.

Authors: Grzelak Lech , Żelazkowska Monika , Szajerska Agnieszka , Szostak Mateusz
Published: February 2024

Introduction. In the era of contemporary changes and evolution of the nursing profession, changing work standards and ergonomics, the professional group of people suffering from cervical spine problems is growing. So far, little research has been conducted on the occurrence of spine problems and their impact on the quality of life of professionally active nurses.

Aim. The aim of the study was to analyse and assess the impact of cervical spine complaints on the quality of life of professionally active nurses.

Material and Methods. The research was conducted among nursing staff employed in the surgical and preventive departments of the Specialist Municipal Hospital of Nicolaus Copernicus in Toruń. The study group consisted of 100 people, women and men, of whom 80 were qualified for further stages of the study. The prospective studies used survey techniques as well as observation and measurement. In the assessment of dysfunctions related to spinal problems, the Polish version of the questionnaire, the indicator of disability caused by pain in the cervical spine — Neck Disability Index (NDI), was used.

Results. The analysis of the conducted research shows that the majority of respondents significantly experience increased pain resulting from work-related stress. Statistical analysis showed that the demographic factors influencing the occurrence of pain are: age (p=0.001), work experience of the respondents (p=0.003) and work system (p=0.026). There was no relationship between gender (p=0.726), marital status (p=0.528) and education of the respondents (p=0.507) and the occurrence of pain.

Conclusions. 1. Work-related stress significantly increases the incidence of cervical spine problems among nurses and worsens their quality of life. 2. The most common complaints among professionally active nurses are headaches and tingling and numbness in the limbs. 3. The occurrence of ailments is determined by demographic factors. 4. Professionally active nurses describe their quality of life as average. 5. The nursing team does not consult a doctor before implementing pharmacological treatment. (JNNN 2023;12(3):127–133)

Abstract The aim of this research was to assess the learning efficacy and level of satisfaction of university students as they adapted to the online teaching model amid the restrictions imposed as a result of COVID-19. The sample consisted of 467 students attending a public University of Spain. The study applied a structural equations methodology with a triangulated approach. The results show that the most influential factor in student online learning satisfaction is teacher-student interaction. On the other hand, student learning efficacy mainly depends on their attitude towards the use of technology; this makes it essential to understand which elements of the online learning system facilitate and incentivize the creation of a good learning environment. Moreover, the design quality of the system and the tools that make it function, and how they link to content and competences, all directly influence perceived ease-of-use and student satisfaction with online teaching.Key words: COVID-19; e-learning; satisfaction; structural equations; university.---Sažetak Cilj ovoga istraživanja bio je procijeniti učinkovitost učenja i razinu zadovoljstva studenata tijekom privikavanja na online nastavu uslijed ograničenja nametnutih zbog pandemije bolesti COVID-19. Uzorak ispitanika sastojao se od 467 studenata državnoga sveučilišta u Španjolskoj. U istraživanju je primijenjena metodologija strukturnih jednadžbi i pristup triangulacije. Rezultati pokazuju da je najutjecajniji faktor zadovoljstva učenjem u online okružju interakcija između studenta i nastavnika. S druge strane, učinkovitost učenja najviše ovisi o njihovim stavovima prema korištenju tehnologije. Zbog toga je nužno razumjeti koji elementi učenja u online okružju pomažu i potiču stvaranje dobroga okružja za učenje. Štoviše, kvaliteta dizajna sustava, alati koji im omogućuju rad te kako se oni povezuju sa sadržajem i kompetencijama zajedno izravno utječu na percepciju lakoće korištenja i na zadovoljstvo studenata online nastavom.

Published: February 2024

AbstractBased on the right to equal access to quality education for all learners, inclusive education contributes to overall social inclusion, allowing children with disabilities to engage and interact with other pupils in line with their abilities, predispositions, and interests. Based on the social model, this paper aimed to examine the perceptions and experiences of instrumental music teachers about the inclusion of learners with disabilities in primary music education. The research study took place in 2021 on a sample of instrumental music teachers (N=9) employed at public primary music schools. Semi-structured online interviews and thematic analysis served to collect and process the empirical data. According to the research results, instrumental music teachers identified both challenges and the positive and negative aspects of teaching learners with disabilities. Teachers considered their formal education inadequate regarding teaching learners with disabilities and expressed the need to advance their competencies for the area.. Among the barriers to inclusion, they observed a shortage of curricula for teaching learners with disabilities and inadequate methods for assessing learning outcomes. Finally, teachers signalled a need for improvements concerning human resources and organisation, which could enhance the inclusion mechanisms in music education.Keywords: conservatory; music education; qualitative analysis.---SažetakObrazovna inkluzija, kao jedan od aspekata inkluzije, temelji se na pravu kvalitetnoga obrazovanja svih učenika podjednako, čime se djeci s teškoćama omogućuje da zajedno s drugim učenicima sudjeluju i surađuju prema svojim sposobnostima, mogućnostima i interesima. Ovaj rad temelji se na socijalnom modelu i cilj mu je steći uvid u mišljenja i iskustva učitelja instrumenata o inkluziji učenika s teškoćama u osnovnim glazbenim školama. Istraživanje je provedeno 2021. godine na uzorku učitelja instrumenata zaposlenih u javnim osnovnim glazbenim školama (N = 9). U svrhu prikupljanja empirijske građe korišten je polustrukturirani online intervju, a dobivena građa podvrgnuta je tematskoj analizi. Rezultati istraživanja pokazuju da učitelji instrumenta u svojem radu s učenicima s teškoćama prepoznaju određene izazove te pozitivne i negativne aspekte rada. Mišljenja su da je njihovo formalno obrazovanje za učitelja instrumenta bilo neadekvatno za rad s učenicima s teškoćama te prepoznaju potrebu za razvojem dodatnih, specifičnih kompetencija za rad s njima. Kao prepreke inkluziji prepoznaju nepostojanje nastavnoga plana i programa za rad s učenicima s teškoćama te postupke provjere znanja i sposobnosti učenika. Njihova iskustva ukazuju na potrebu stvaranja kadrovskih i organizacijskih preduvjeta za primjenu načela inkluzije u glazbenom odgojno-obrazovnom sustavu.Ključne riječi: glazbeno obrazovanje; kvalitativna analiza, muzička akademija.

AbstractThis study examines whether and how student feedback and experience in using E-Learning affect mediator variables such as perceived ease of use and learning outcomes in the field of education. It also examines how mediators should influence the success of E-Learning. Seven hundred and thirty-four students were recruited for the survey, and the Structural Equation Model (SEM) was used to test the research hypothesis. Empirical results show that student feedback on using E-Learning has a significant and positive effect on perceived ease of use and learning outcomes, further affecting the success of E-Learning use. Furthermore, the mediator variables Perceived ease of use and Learning outcomes have partial mediators between feedback, student experience, and successful use of E-Learning. In this study, participants with higher levels of feedback and experience were more aware of online learning performance. The E-Learning process also strengthens the relationship between students and teachers. Research results from students feedback and experience in using E-Learning can provide important information for the existence and success of learning in the future.Key words: student feedback; student experience; perceived ease of use; learning outcomes, successful use of E-Learning.---SažetakU ovome istraživanju ispituje se utječu li, i u kolikoj mjeri, povratne informacije studenata i njihova iskustva u korištenju e-učenja na medijatorske varijable poput percipirane lakoće korištenja i ishoda učenja u području obrazovanja. Također se ispituje kako bi medijatorske varijable trebale utjecati na uspješnost e-učenja. U istraživanju je sudjelovalo 734 studenata, a za testiranje hipoteza istraživanja korišten je model strukturne jednadžbe. Empirijski rezultati pokazuju da povratne informacije studenata o korištenju e-učenja imaju značajan i pozitivan utjecaj na percipiranu lakoću korištenja i ishode učenja, što dalje utječe na uspješnost primjene e-učenja.

Influencing factors of plant habitat, phenophase, and organ on the essential oil composition of Agastache rugosa
Authors: Fan H. , Nie A.Z. , Ge Y.J. , Weng L. , Gao Y. , Chen F. , Shen H.J.
Published: February 2024

Agastache rugosa (Fisch. et Mey.) O. Ktze, also known as “Suhuoxiang” (SHX), has been cultivated for more than three hundred years as a valuable aromatic edible and medicinal plant in Jiangsu Province, China. The volatile compounds of SHX from various habitats were investigated by HS-SPME-GC-MS, detecting sixty-five chemical constituents with menthone, pulegone, and estragole being the major volatile compounds. Their relative contents showed various accumulation tendencies in different growth months by GC-MS, with the relative content of menthone gradually increasing, pulegone content decreasing, as well as estragole content climbing initially before declining. This tendency was supported by quantitative experiments using samples from various habitats, which also revealed that the full-bloom stages exhibited the highest total concentrations of menthone and pulegone. The volatile composition of SHX in various plant organs differed, with palmitic acid being the main volatile component of stems, while menthone and pulegone being the core volatile components of leaves and spikes, implying that leaves and spikes should be separated from the stem to obtain higher drug contents. The current findings provide new information for SHX cultivation and applications.

Published: February 2024

An ion chromatographic method and its application have been described to quantify nine cationic components (lithium, sodium, ammonium, methylammonium, potassium, magnesium, calcium, strontium, and barium) in pyrotechnics (firecracker and firework) samples. The samples in this study were purchased from local shops in Ternate City, North Maluku. The method performed a mixed eluent with 4 mM HNO3 and 0.015 mM Na2EDTA, combined with a Metrosep C4-150/4.0 separation column for all quantifications. Excellent chromatograms were achieved, and the nine cationic components were eluted in less than 18 min. The calibration graphs of the quantifications were linear in the range of 1.25–37.5 mg L−1. The detection limit (LOD) at S/N = 3 was below 0.098 ppm (mg L−1). This method was applied to the pre-blast and post-blast residues of pyrotechnics samples, and the simultaneous quantification of the nine cationic components in these samples was achieved with satisfactory results.

Published: February 2024

This paper presents an investigation on a battery-less voltage of Piezoelectric (PZT) V-shape cantilever beam Energy Harvester (EH) using human body vibration. The frequency ranges are walking (0–5 Hz), running (6–10 Hz) and motions (11–15 Hz) for human movement. Pacemaker devices typically require a lower resonant frequency with higher voltage which is powered by batteries. The battery has a limited duration during its working process and the battery is difficult to replace in the human body. To address the aforementioned issue, a V-shape cantilever beam EH has been developed as a solution to overcome these limitations. The cantilever beam was designed in COMSOL Multiphysics software 5.5 version using the Finite Element Analysis (FEA) method for experimental investigations followed by three categories of frequency ranges of the human body. The simulation results showed that the generated battery-less higher voltage was 269 mV (AC) at the resonant frequency of 14.37 Hz in the motion range of 11–15 Hz. Later, an Ultra Low Power (ULP) electronic circuits will be designed and simulated in the LTSPICE software to convert and boost-up from 269 mV (AC) to DC voltage attained. The estimated output power of the energy harvester system can be powered up (4.7 µW) for modern pacemaker applications.

Published: February 2024

In this article I discuss the question: „What is mathematics really all about?” How mathematics is viewed is significant on many levels, especially in education and society. For many years, sociologists of mathematics education, have stressed that mathematics acts as a gatekeeper: mathematics more than any other subject, has been cast in the role as an ,,objective” judge. The main purpose of this article is to conjoin several sets of problems such as the mathematical underparticipation of women and ethnic minorities , the sense of cultural alienation from mathematics felt by many social groups, mathematics in the process of transmission of social and political values, its role in the unequal distribution of power and the social nature of mathematics as a discipline.

The paper contains the demand side of the market for cultural goods and services, with a focus on performing arts especially the analysis of their consumption from the demand theory, which attempts to explain the motives and consequences of consumers’ decisions. The consumption of cultural goods and services is determined by many factors, and their identification is the purpose of this study. Among them there are social determinants, including education and age of consumers and economic, such as price and income. The starting point for the analysis is fact that cultural goods and services in the economy are normal goods, so the demand for them increases with increasing consumer income and decreases with the demand decrease. They are also luxury goods, which means they are purchased only when the amount of income will satisfy customers’ basic needs. The paper contains also review of results of research conducted by foreign authors to demand determinants for cultural goods and services. Selected determinants are presented using statistical data on participation in culture of citizens of the European Union.

Aim. To assess adherence to a healthy lifestyle depending on the individual and socio-economic characteristics of the Russian population (according to the Epidemiology of Cardiovascular Diseases and their Risk Factors in Regions of Russian Federation-3 (ESSE-RF3) study), followed by a comparative analysis with ESSE-RF2 (2017).

Material and methods. The analysis was carried out based on research data from ESSE-RF2 in 2017 and ESSE-RF3 in 2020-2022. The healthy lifestyle adherence index included following parameters: no smoking; sufficient consumption of vegetables and fruits; physical activity; no excessive salt intake and alcohol abuse. Three following categories of adherence to a healthy lifestyle were analyzed: high, satisfactory, low. From individual variables, individual socio-economic characteristics with the highest evidence level of influence on healthy lifestyle were taken.

Results. In the ESSE-RF3 sample, 47,2% of respondents had low adherence to a healthy lifestyle, 37,2% — satisfactory, and 15,6% — high. Women are more committed to healthy behavior compared to the male population — 19,6 vs 11,1% (p<0,001). The lowest adherence to a healthy lifestyle was found among men with low incomes who do not have higher education and is typical for younger people. Analysis of changes from 2017 to 2020-2022 revealed that adherence to a healthy lifestyle among the population decreased mainly due to a decrease in the proportion of people with high adherence.

Conclusion. The study made it possible to characterize the current level of healthy lifestyle among the population and demonstrated the most promising strategies aimed at improving adherence to a healthy lifestyle among the Russian population.

Advances and challenges in animal source food inspection legislation for Brazilian small-scale and artisanal producers
Authors: Vasconcelos Tassia Cristina Bello de
Published: February 2024

Abstract: The strict sanitary inspection legislation of animal source food has been considered a trade barrier for smallholder farmers and small-scale producers in Brazil. In this sense, law flexibilization is suggested to facilitate national trade of these products. We conducted a social and sanitary analysis, presenting the current Brazilian conjuncture and difficulties for animal source food Brazilian inspection law flexibilization. By discussing inequalities, human rights issues, animal source food legislation, and international food safety standards, we evidenced critical barriers for legislative reform in Brazil. Among these barriers, the main ones are social inequalities; high zoonotic risk of animal source food products; the Brazilian political structure and its reflection on different inspection practices among country jurisdictions; and the lack of inspection services in most Brazilian municipalities. At the same time, we present positive updates in the normative framework, and point out game-changers to modify the actual safety and trade situations of Brazilian small-scale and artisanal animal source food products, including policies to strengthen state and municipal inspection services and harmonization initiatives based on international standards and national legislation. We also suggest policies to implement inspection services in municipalities, whether by municipal action or by a consortium, as well as policies to strengthen technical assistance and rural extension for small-scale and artisanal producers. These policies aim to reduce technical and sanitary education inequalities and build a fairer animal source food system.

Os objetivos foram descrever a prevalência de baixo peso e excesso de peso, avaliados pelo índice de massa corporal (IMC), estratificada por sexo e faixa etária, e analisar as características sociodemográficas associadas ao IMC em mulheres e homens mais velhos. Trata-se de uma análise transversal de 8.974 participantes com ≥ 50 anos da linha de base do Estudo Longitudinal da Saúde dos Idosos Brasileiros (ELSI-Brasil, 2015-16). O IMC foi classificado em baixo peso, eutrofia e excesso de peso de acordo com a idade do participante. Foi utilizado modelo de regressão logística multinominal, considerando-se as características sociodemográficas de mulheres e homens. Os resultados evidenciaram maior prevalência de excesso de peso nas mulheres em comparação aos homens (64,1% vs. 57,3%). Em ambos os sexos, a prevalência de baixo peso foi maior nos mais longevos, enquanto que o excesso de peso foi menor. Nas mulheres, a chance de baixo peso foi maior do que a chance de eutrofia naquelas solteiras/viúvas/divorciadas (OR = 1,95; IC95%: 1,42-2,66) e nas residentes na área rural (OR = 1,58; IC95%: 1,01-2,49), ao passo que a chance de excesso de peso foi menor do que a chance de eutrofia nas residentes na área rural (OR = 0,78; IC95%: 0,62-0,97) e em todas as macrorregiões geográficas relativas à Região Sul. Para os homens, a chance de excesso de peso foi menor do que a chance de eutrofia entre solteiros/viúvos/divorciados (OR = 0,58; IC95%: 0,48-0,69). Os mais ricos apresentaram menor chance de baixo peso (OR = 0,59; IC95%: 0,38-0,90), bem como maior chance de excesso de peso (OR = 1,52; IC95%: 1,20-1,92). Em conclusão, as características sociodemográficas associadas ao IMC diferiram entre os sexos.

Abstract The aim of this study was to investigate the association between maternal and paternal licit and illicit drug use, smoking and drinking and autism spectrum disorder (ASD). We conducted a case-control study with children and adolescents diagnosed with ASD and neurotypical individuals. The data were collected using a semi-structured questionnaire administered during interviews with the children’s mothers or guardians. The following variables were analyzed: child sex and age; maternal and parental age; use of medicines before and during pregnancy; classes of medicines used during pregnancy; maternal and paternal smoking; maternal and paternal drinking; maternal and paternal illicit drug use. The data were analyzed using logistic regression and crude and adjusted odds ratios (OR). After adjustment, the results showed an association between maternal use of antipyretics/pain killers during pregnancy (OR = 2.26; 95%CI 1.29-3.95; p < 0.040) and ASD. No association was found between maternal and paternal smoking, drinking and illicit drug use before and during pregnancy and ASD. The findings suggest that the development of ASD is influenced by environmental factors.

Abstract We conducted a socio-historical study covering the period 1979-2014 to explore the genesis of LGBT health policy in Bahia, Brazil, drawing on Pinell’s theoretical framework for the sociological analysis of public policy. To analyze the social space, we investigated the trajectories of the agents involved in policy formulation and the relations between these agents and the national social space and field of State power. The agents were predominantly from the scientific, human rights, sexual rights, feminism and AIDS fields, and had a high level of bureaucratic and militant capital, meaning they were well-versed in LGBT health issues. The historical conditions of possibility underlying the formulation of LGBT health policy included the formalization of the State Technical Committee on LGBT Health in 2014, in an effort to improve access to comprehensive health care for vulnerable groups; and the Bahia without Homophobia plan, which helped expand dialogue around with civil society and social movements and address the main criticisms of policy making.

Abstract A number of studies have focused on the evaluation of the relationship between pre-pregnancy overweight and polyunsaturated fatty acids content in human milk. However, given the complexity of potentially confounding risk factors, the use of graphical tools is recommended to identify possible biases. This article aims to propose a theoretical model of causality using the directed acyclic graph between pre-pregnancy overweight and polyunsaturated fatty acids content in human milk. Methods: An extensive literature review was performed to identify variables with causal relationships with exposure and/or outcome. The choice of variables for adjustment followed the graphic algorithm that comprises six criteria for selecting a minimum set of potentially confounding variables. Socioeconomic conditions, interpartum interval, maternal age and food consumption pattern were the variables that would have to be adjusted in order to estimate the total effect of pre-pregnancy overweight on polyunsaturated fatty acids content in human milk. The minimum set of variables found in the present study can be used in the analysis of other studies that evaluate this association.
