Deacidification and esterifaction of waste cooking oil: Comparison of the coupled process with stand-alone catalytic esterification and extraction processes
Authors: Lu Xianghong , Zhang Yi , Yu Yunliang , Ji Jianbing
Published: July 2023

The free fatty acids in waste oil with high acid value were removed and transformed into fatty acid methyl esters by the extraction-reaction coupled process. The de-acidification efficiency and esterification conversion in the extraction-reaction coupled process were studied and compared with those in the stand-alone extraction process and the esterification process, respectively. Compared with cross-current batch extraction, the de-acidification efficiency of the extraction-reaction coupled process was equivalent to that of seven equilibrium stages in the conditions of the oil/methanol mass ratio of 1:1 at 60 oC. Compared with the esterification process, the esterification conversion of the coupled process was 90.3%, which is much larger than 46% in the esterification process at the reaction time of 32 minutes. Based on these findings, it is suggested that the extraction-reaction coupled process is a very effective and promising method for biodiesel production from oils having high acid value.
Biopulping and its potential to reduce effluent loads from bleaching of hardwood kraft pulp
Authors: Yadav Ravi Dutt , Chaudhry Smita , Dhiman Saurabh Sudha
Published: July 2023

Mixed hardwood chips were treated with lignin-degrading fungi to study the effect of fungal pretreatment on bleaching characteristics of kraft pulp. Pretreated wood chips were subjected to reduced active alkali doses in comparison to untreated chips. Comparable results were obtained for pretreated chips with reduced alkali dose as was obtained with higher dose of alkali in case of untreated chips. Fungal treatment made the process more energy-efficient, and 4.8% less chlorine was consumed in comparison to the control process. Pretreatment with Ceriporiopsis subvermispora was responsible for reduction of 4.7% in lignin contents, 14.3% permanganate number, and overall reduction of 15.5 kg/T of Cl2 consumption. The pollution load in terms of COD and BOD at the CD stage was reduced by 32.6% and 41.5% respectively, whereas 12% reduction in AOX compounds was observed in effluent of pretreated pulp.
Thermomechanical behavior of sisal fibers grafted with poly(acrylamide-co-N-vinyl-2-pyrrolidone) and loaded with silver ions or silver nanoparticles
Authors: Chand Navin , Bajpai S. K. , Joshi Ruchi , Mary Grace
Published: July 2023

The graft copolymerization of acrylamide, N-vinyl-2-pyrralidone and N, N’-methylene-bis-acrylamide was carried out to modify the sisal fiber to improve its mechanical and thermal stability. The grafting of poly-(acrylamide-co-N-vinyl-2-pyrrolidone) on sisal fiber surfaces facilitated the loading of Ag(I) ions and Ag(0) nanoparticles. Surface microstructure of the surface modified sisal fiber confirmed the grafting of the copolymer. The XRD and FTIR graphs also showed changes on grafting and on Ag(I) ions and the loading of Ag(0) nanoparticles. It is evident from the DSC curves that the initial thermal stability was improved by delaying the hemicellulose decomposition on grafting and silver ion loading.
Chemical modification of solid wood and wood raw material for composites produciton with linear chain carboxylic acid anhydrides: A brief review
Authors: Papadopoulos Antonios N.
Published: July 2023

This paper reviews recent results in the field of chemical modification of wood with linear chain anhydrides. Though the main focus is on work performed by the author, this is described in the context of related progress in the field. The combined research has demonstrated the effectiveness of chemical modification applied to solid wood and wood raw material for composites production in overcoming the main disadvantages of wood. Wood samples and wood chips/strands have been chemically modified with a series of anhydrides at equivalent levels of modification, under identical conditions, and the question was to determine which is the primary factor controlling the biological durability, the degree of cell wall bulking by the bonded adduct, or the extent of hydroxyl substitution. The results have clearly indicated that the degree of cell wall bulking caused by the adduct, rather than the extent of hydroxyl substitution, is the primary factor controlling the biological durability and water vapour sorption. Despite the large difference in OH substitution level, reaction with different anhydrides results in the same level of protection against decay, marine borers and termites, and in the same level of water vapour sorption. These observations suggest that the mechanism of protection is not chemical/biochemical in origin, but relates to the bulking of the cell wall by the reacted adduct.
Possible trends of renewable organic fillers and pigments derived from natural resources for sustainable development of paper industry
Authors: Shen Jing , Song Zhanqian , Qian Xueren
Published: July 2023

The use of traditional inorganic fillers and pigments for both filling and coating applications in papermaking may have certain limitations in such aspects as recyclability and combustibility. Novel renewable organic fillers and pigments derived from natural resources can possibly be completely recyclable, combustible, biodegradable, and environmentally friendly, and they can potentially be used as substitutes for inorganic fillers and pigments to improve the recyclability and other properties of the paper products. Although there are still challenges lying ahead, the strategic significance of the use of renewable organic fillers and pigments for the sustainable development of papermaking industry is an indisputable and demonstrable fact.
Potential fungi for bioremediation of industrial effluents
Authors: Saritha Vara , Maruthi Y. Avasn , Mukkanti K.
Published: July 2023

Two fungi (unidentified) were isolated from soil and marine environ-ments. These isolates were used for bioremediation of pulp and paper mill effluent at the laboratory scale. The treatment resulted in the reduction of color, lignin, and COD of the effluent in the order of 78.6%, 79.0%, and 89.4% in 21 days. A major part of reductions in these parameters occurred within 5 days of the treatment, which was also characterized by a steep decline in the pH of the effluent. The enzyme activity of these fungi was also tested, and the clearance zone was obtained in the plate assay.
Proactive Service Recovery Performance in Emerging (vs. Developed) Market-Based Firms: The Role of Clients’ Cultural Orientation
Authors: Bakhsh Naghmeh Nik , Hollebeek Linda D. , Riivits-Arkonsuo Iivi , Clark Moira K. , Casas Ramunas
Published: July 2023

Though service recovery plays a key role in industrial clients’ post-recovery supplier evaluations, the impact of customers’ cultural orientation on the effectiveness of supplier-instigated proactive recovery (i.e., a supplier’s recovery efforts before clients notice/complain) remains tenuous, particularly in emerging (vs. developed) markets. Addressing this gap, we develop a model that examines (a) the moderating role of clients’ cultural orientation on the association of supplier-instigated proactive recovery and client-perceived recovery-related justice, and (b) the impact of customer-perceived justice on relationship quality in the emerging (vs. developed) market context. To test the model, we deploy a cross-cultural scenario-based experiment using 117 Danish industrial clients (i.e., developed market) and 109 Iranian industrial clients (i.e., emerging market). The results suggest that customers’ cultural orientation partially moderates the relationship of suppliers’ proactive recovery and customer-perceived justice, in turn boosting relationship quality in the emerging/developed market context.
How Sexualised Images in Advertisements Influence the Attention and Preference of Consumers with a Modern View
Authors: Pentus Kristian , Ruusu Mariia , Kuusik Andres , Dorokhova Liudmyla , Ploom Kerli
Published: July 2023

This paper aims to determine how using sexualised images in advertisements influences the attention and preference of consumers with a modern attitude towards gender stereotypes.

This research used a methodological approach based on eye tracking of the perception of advertising images – an eye-tracking study measured how the general attitudes towards gender roles mediate attention. A control question for attitudes towards gender stereotypes was used. The degree of preference for advertising was also examined in the study.

The results show that sexual stimuli are not more eye-catching than non-sexual, as sexual advertisements do not capture attention faster and are not viewed for a longer time than non-sexual advertisements.

The originality and value of the study lies in the fact that the article supports the right marketing decisions to overcome gender stereotypes in advertising, to avoid advertising errors associated with unjustified sexualisation and eroticisation of visual advertising images and models. It also suggests directions for future research on various aspects of gender stereotypes in advertising.

A potencialidade da metodologia de pesquisa narrativa em estudos qualitativos na área de políticas públicas educacionais
Authors: Bourguignon de Lima Camila
Published: July 2023

O estudo retoma teoricamente o potencial da narrativa e sua contribuição como percurso metodológico em pesquisas qualitativas no campo da análise de políticas educacionais no Brasil. O objetivo é situar a metodologia narrativa de pesquisa em educação na análise de políticas públicas, enfatizando o seu uso para compreender a conexão entre a dimensão dos sujeitos na sua relação com o contexto e a dimensão coletiva nas estratégias de ação em um programa ou prática organizacional. A narrativa, em consonância com Rodrigues e Prado (2015), Serodio e Prado (2017), e Prado, Soligo e Simas (2022), é uma prática discursiva que viabiliza a atribuição de sentido às experiências e vivências que emergem do cotidiano do trabalho na área da educação. Dado seu caráter dialógico e de valorização da subjetividade, a pesquisa narrativa é marcada por produções onde o pesquisador ou a pesquisadora falam com os sujeitos e a partir deles, caminhando na direção da superação da dicotomia sujeito-objeto. Interpreta-se que a pesquisa narrativa no campo das políticas públicas educacionais possibilita um conjunto relevante de perspectivas a se relacionar com o problema político, contemplando os elementos singulares que configuram as histórias, com os quais a realidade, ela própria, se modifica.
A relação do sujeito com a tecnologia na perspectiva Freireana
Authors: Ramos André , Costa Luciano Andreatta Carvalho da
Published: July 2023

O objetivo deste artigo é refletir através da perspectiva freireana, o potencial da utilização das Tecnologias de Informação e Comunicação (TIC's) na escola, contribuindo na emancipação e socialização dos sujeitos, além da objetificação deles. Esta problematização parte da relação epistemológica entre sujeito e realidade presente na obra de Freire, resultando no conceito de ruído tecnológico. Foi utilizado no presente estudo a metodologia qualitativa, com critérios de análise do tema proposto criados após pesquisa bibliográfica, e realização de grupo focal com professores da rede pública e privada do Litoral Norte do Rio Grande do Sul. Como resultado, constatou-se que existe um desconforto na relação do sujeito com a tecnologia no âmbito dos espaços escolares, ampliando a necessidade de se discutirem os aspectos relacionado ao quanto a sociedade está, em sua maioria, sendo beneficiada ou não com os avanços tecnológicos.
Rock is Dead, Long Live Rock
Authors: Legendre Thomas
Published: July 2023

Kilmartin Glen’s rock art and built structures suggest activities dedicated to decentring human individuality and agency, paradoxically through heightened sensory experience. This process of “losing oneself” in time and place may be understood in terms of Object-Oriented Ontology (OOO), rejecting subject–object relationships in favour of a “flat ontology” of object–object relations in which life or sentience receives no privileged status. OOO’s explication of metaphor, rooted in a schema of essence and appearance, and further supported by cognitive linguistics, serves as a basis for erasing not only the distinction between the literal and metaphorical but also, with additional consideration of the implicate order as described by physicist David Bohm, the organic and inorganic. Taken together, these approaches allow us to understand ritual activity involving music and contact with “dead” stone at astronomically significant moments as a method of “attunement” to the continuity between terrestrial/celestial and animate/inanimate, consistent with contemporary efforts to reconcile classical and quantum physics as it confronts the subjunctive nature of reality itself.

A FORMAÇÃO DOS MEDIADORES E CONCILIADORES JUDICIAIS: REFLEXÕES E DESAFIOS DA CAPACITAÇÃO NO BRASIL
Authors: Gampert Tamília , Crippa Anelise
Published: July 2023

Diante do crescimento da atividade institucional do Poder Judiciário e da implementação de uma cultura do consenso, o presente artigo analisa a promoção dos meios consensuais a partir da Resolução nº 125/2010/CNJ e do CPC/2015, discorrendo sobre o necessário contraponto entre as culturas da sentença e do consenso e, a partir dessa análise, averigua se as mudanças na processualística cível são instrumentos de efetivação do direito ao acesso à justiça, pois os institutos da mediação e da conciliação não são apenas soluções para a crise da justiça, mas sim meios de restauração da paz social. Apoiada no diálogo como principal ferramenta, a mediação tem sido utilizada em diversos contextos como meio para lidar com os dissensos. Diante do crescente estímulo às mediações no âmbito jurídico brasileiro é fundamental pensar sobre formação adequada de mediadores a fim de qualificar a sua atuação. Apesar da escassez de pesquisas sobre o tema, a literatura existente aponta para os desafios de uma abordagem não tecnicista que enfatize o desenvolvimento de sensibilidade e mudanças paradigmáticas. Diante disso, este trabalho objetiva investigar as reflexões e desafios da capacitação no Brasil.
The Segmentation, Targeting and Positioning Marketing Model applied to Scientific Health Research
Authors: Correia Tiago M , Rodrigues Maria
Published: July 2023

Currently, in the scientific health research (SHR) field, there is a narrow focus in the pursuit of highly ranked journals with higher impact factors, based on citation models and journal ratings. This limitation often leads to undervalue the relevance of scientific studies by prioritizing citation impact. This limitation is a direct result of the funding needs inherent in the fields of natural sciences and engineering, where investments in equipment and infrastructures are considerably higher compared to other research areas. In the present article, the authors aimed to contribute to SHR by combining Marketing concepts, particularly the Segmentation, Targeting, and Positioning model (STP Marketing model), to the development of scientific research projects in the healthcare sector. By applying these concepts in research projects design and researchers career progression, a more comprehensive understanding can be achieved of how individuals or institutes are perceived. Furthermore, the implementation of effective STP Marketing strategies will enable researchers and institutes to gain a competitive advantage in the market by treating articles as products that require strategic positioning in a highly competitive environment. Ultimately, researchers should keep in mind that their ultimate audience is the journals audience they are targeting, as their objective is to publish in a journal that aligns with their specific goals.
Effect of heating–cooling regimes on the compressive strength of alfa fibre concrete
Authors: Ben Hammed Zied , Sabeur Hassen , Ben Ouezdou Mongi
Published: July 2023

In the first part of this research study, concretes with different dosages of alfa fibre were formulated. At ambient temperature, the results showed that the incorporation of 1% per volume of concrete of untreated alfa fibre (UAF) yielded the highest mechanical values among the alfa fibre concretes. The addition of alfa fibres produced an increase in ductility, compared with the no-fibre concrete. In the second part, specimens of ordinary concrete (OC) and concretes with polypropylene fibres, treated alfa fibre (TAF) and UAF were heated to various temperatures up to 800°C, with an average heating rate of 7–8°C/min, in steps of 100°C, maintained for 3 h. At the end of these heating rates, two cooling regimes were applied: air cooling or water cooling. The impact of these heating–cooling regimes was assessed through a study of the residual compressive strength. For both regimes and for all types of fibre concretes, the compressive strength drastically reduced up to 800°C with linear tendencies. More damage was observed in the fibre concretes quenched in water. For both cooling regimes, the use of alfa fibres led to an improvement in the residual compressive strength compared with OC, more particularly in the temperature range 500–800°C.
Examining the criteria for contact erosion in granular soil foundations
Authors: Wang Gang , Yang Jing , Jin Wei , Deng Zezhi , Zhang Zihao
Published: July 2023

Contact erosion, or interfacial erosion, often occurs in layered foundations composed of coarse and fine layers; it refers to the phenomenon that the particles of the fine layer are detached by the flow parallel to the interface and transported through the pore channels of the coarse layer. To visualise the initiation and progression of contact erosion at the internal interface of soil strata, transparent soil model tests were employed to simulate real soil, and a series of contact erosion tests was conducted on double-layer foundations composed of different coarse and fine layers. Based on the test results, the commonly used geometric and hydraulic criteria for contact erosion were examined. It is shown that the geometric criteria are reliable, while hydraulic criteria give diverse results. For the same fine soil layer, the critical hydraulic gradient varies greatly with the coarse soil layer, while the critical flow velocity varies in a relatively small range since flow velocity has an intrinsic relationship with the dragging force imposed on particles by seepage flow. More efforts should be invested on the criteria based on critical velocity in further studies of contact erosion.
Grupalidad curadora
Authors:   Universidad Cooperativa de Colombia, Parra Valencia Liliana
Published: July 2023

This book aims to socialize the results of the doctoral research in the Montes de María territory (Sucre and Bolívar, Colombia), whose central proposal is that the curator groupality of the communities has allowed them, on their own account and with what they have at their disposal, to keep alive their knowledge to face the pains of war. The curator groupality, as an alternative to the modern/colonial psycological perspective, is structured from the therapeutic, emancipatory and cosmological-spiritual multidimensionality. In order to trace the silence of local knowledge, the way of studying curator groupality focused on the peasant and afro-indigenous community healing practices themselves. Getting closer to the daily life of montemarian communities allowed me to identify a therapeutic potential such as group psychotherapy. The inspiration to study the curator groupality, from its practices of everyday life, communitary and decolonial, was the encounter with leaders of Asocares, peasant women of San Francisco, Medellín, Villa Colombia and the traditional Palenquero and Zenú doctors of the Montes de María. Thus, I identified three curator grupality practices: 1) mobilizing as an antibiotic to assimilate the pains of war, 2) take care and heal with plants, and 3) wakes. The curator groupality from a decolonial perspective, problematizes the knowledge of the modern/colonial cure, and proposes a field of study capable of mobilizing disciplinary implosion, interdisciplinary dialogue and transdisciplinary openness. It is configured in an urgent call for decolonization not only of Psychology and Social Sciences, but also of public policies on health, education, research and reparation. The transdisciplinary study of community healing implies an epistemological and political stance, situated in the world of life.

Published: July 2023

O presente estudo teve como objetivo identificar por meio da literatura quais são as ações inclusivas no contexto da educação infantil no Brasil para o acompanhamento pedagógico junto a crianças com deficiência intelectual. Foram utilizados descritores em língua portuguesa: “inclusão na educação”, “educação inclusiva”, “deficiência intelectual”, “crianças com deficiência intelectual”,“educação infantil’’, e encontradas 1.310 publicações nas bases de dados eletrônicas Lilacs, Scielo e PEPSIC. Após avaliação, 5 estudos preencheram os critérios de inclusão. A revisão revelou que a inclusão das crianças com deficiência intelectual está ocorrendo na educação infantil, mas os professores ainda não se sentem preparados para atuarem, algumas das práticas relatadas indicam que ainda se pensa apenas na socialização e nos cuidados físicos e um reduzido número de artigos discute metodologias de ensino e estudos experimentais; predominância de estudos de caso e descritivos, o que demonstra a necessidade de novas investigações; que evidenciem ações inclusivas efetivas na educação infantil no contexto brasileiro principalmente para que estas sirvam de referência para os professores da educação infantil.
Sexismo en chicas adolescentes: análisis comparativo entre población general y de medidas judiciales
Authors: Gil Llario Mª Dolores , Ortas Barajas Francisco , García Montoliu Carlos , Estruch García Verónica , Ballester Arnal Rafael
Published: July 2023

El sexismo es definido como una actitud de animadversión y discriminación dirigida hacia las personas en base a su categoría sexual o género, sustentando las relaciones de desigualdad entre hombres y mujeres. Glick y Fiske (1996), en su teoría del sexismo ambivalente, lo conceptualizan como un constructo bidimensional conformado por el sexismo hostil y el sexismo benevolente. Asimismo, la adolescencia ha sido identificada como una etapa evolutiva clave en el desarrollo de creencias y manifestaciones sexistas, existiendo evidencia acerca de mayores niveles de sexismo en poblaciones vulnerables. Por ello, el presente estudio tiene por objetivo comparar actitudes sexistas entre dos grupos de mujeres adolescentes: las que se encuentran bajo medidas judiciales (MJ) y población general (PG). Para ello se diseñó un estudio cualitativo mediante el uso de la técnica focus group en el que participaron un total de n=13 mujeres adolescentes con un rango de edad de entre 16 y 19 años, creando dos grupos focales en función de su contexto -MJ y PG-. A partir del análisis del discurso se identificó una predominancia del sexismo hostil en el grupo MJ, mientras que el grupo de PG presentó una mayor ambivalencia y equilibrio entreactitudes hostilesy benevolentes. En este sentido,en elsegundo grupo se detectó una mayor conciencia y crítica hacia actitudes sexistas, señalando en reiteradas ocasiones el rechazo hacia las mismas. Además, los argumentos ofrecidos por el grupo MJ evidencian la interiorización de diferentes mitos del amor romántico, entendiendo los celos como una muestra de amor y aceptando la compatibilidad de amor y maltrato en relaciones de pareja. Los resultados coinciden con hallazgos obtenidos en estudios cuantitativos sobre el mismo constructo e indican la pertinencia de implementar medidas preventivas a diferentes niveles, contemplando las necesidades específicas de poblaciones vulnerables. El presente estudio ha sido realizado en el marco de un proyecto financiado por la Conselleria d’Innovació, Universitats, Ciència i Societat Digital (Generalitat Valenciana) [AICO/2021/143].

Published: July 2023

La vida afectivo-sexual en la adolescencia está en constante evolución. En este sentido, hoy en día se continúa luchando por una educación sexual desde edades tempranas. Sin embargo, aunque los avances sean notables, esta educación sexual no es tan frecuente en las aulas ni de forma individualizada. Por este motivo, el estudio busca analizar diferentes variables de la conducta sexual de población adolescente, teniendo en cuenta diferencias de género. Para ello, 250 adolescentes (50% mujeres y 50% hombres), de entre 12 y 16 años, cumplimentaron una batería de preguntas online acerca de su historia afectivo-sexual. Entre los resultados, cabe destacar que el 66,4% de los hombres se habían masturbado en alguna ocasión, con edad de inicio a los 10-11 años (M = 10,22; DT = 4,54). Por otro lado, las mujeres habían llevado a cabo esta práctica en un 29%, con edad de inicio más frecuente a los 12-13 años (M = 12,69; DT = 3,11). El 35,2% de los hombres y el 37,1% de las mujeres habían tenido parejas sentimentales alguna vez, y el 36,4% y 47,8%, respectivamente, tienen en la actualidad. Respecto a las prácticas sexuales, el 21,6% de los hombres y el 21% de las mujeres han mantenido relaciones sexuales alguna vez. En conclusión, los resultados enfatizan la necesidad de abrir los ojos ante la realidad del inicio temprano de la actividad sexual, con el fin de promover la necesidad de una educación sexual temprana.
Adult attachment and minority stress in lesbian and gay people in Italy
Authors: Trombetta Tommaso , Santoniccolo Fabrizio , Valentina Romaniello Caterina , Paradiso Maria Noemi , Rollè Luca
Published: July 2023

As widely demonstrated, minority stress negatively affects well-being of LGBTQIA+ people. Recently, the literature has inquired into the psychological factors that may explain individual differences in levels of minority stressors experienced. In particular, some studies have focused on the role of adult attachment, although further studies seem necessary to understand its impact on proximal minority stressors. Through three multiple regression models, the present research analyzed the impact of adult attachment avoidance and anxiety on perceived stigma, internalized homonegativity and sexual orientation concealment, controlling for theeffect of proximaland distal minority stressors. One hundred and twenty-one people who self-identified as lesbian or gay and were involved in a romantic relationship when completing the questionnaire participated in the research. After controlling for the effect of distal and proximal minority stressors, data support a positive relationship between attachment anxiety and internalized homonegativity, and between attachment avoidance and sexual orientation concealment. However, the latter regression model was not significant. Finally, no significant relationship emerged between adult attachment and perceived stigma. The results are at least in part in line with the scarce literature on the topic. Further studies are needed to further support and extend the data emerging in the present study, in order to inform interventions aimed at promoting the well-being of LGBTQIA+ people.
La superación de estereotipos en niños hacia las personas mayores. Análisis de un programa intergeneracional en el contexto socio-educativo
Authors: Moreno Abellán Pedro , Salmerón Aroca Juan Antonio , Martínez de Miguel López Silvia
Published: July 2023

El estudio presentado examina la imagen que poseen los niños de las personas mayores a través de programas intergeneracionales desarrollados entre centros escolares dependientes de la Consejería de Educación de la Región de Murcia (España) y la red de centros sociales del Instituto Murciano de Acción Social (IMAS). En estos dos escenarios, además de detectar la existencia de ciertos estereotipos por parte del alumnado hacia el colectivo mayor, se pretende conocer de que manera inciden y que aspectos pueden cambiar en todo su proceso hasta la finalización del programa. Teniendo en cuenta los aspectos marcados que facilitan la detección de estereotipos, se ha utilizado una metodología de carácter cuantitativo a través de cuestionarios. Entre los resultados más relevantes, se descubre que el desarrollo de estos programas minimiza ciertos prejuicios y estereotipos hacia la vejez, así como un reforzamiento de la imagen positiva hacia las personas mayores por parte de los niños.
Structural Vulnerability and Toxicity Experiences in the Uruguayan Soybeanisation Process
Authors: Evia Victoria
Published: July 2023

Fuelled by agribusiness, transgenic soybean crops, genetically modified to withstand pesticide use, have increased in use during the last 20 years in the Southern Cone of Latin America. Plantations are understood as examples of ‘modular simplifications’ in ‘patchy Anthropocene’ landscapes (Tsing et al. 2019), where the attempt to reduce diversity may have social and ecological feral effects as diseases and toxins spread. In Uruguay, as an agro-exporter country, soybean expansionist processes correlate with an increased use of pesticides. Based on an ethnographic study (2016–2018) carried out in the main Uruguayan agricultural region, this Research Article seeks to analyse the experiences of toxicity among agricultural workers and rural inhabitants in the soybeanisation context. I propose that pesticide effects transcend biomedical diagnoses of ‘intoxication’. I also contend that the experience of toxicity can be understood as occurring along a continuum in the daily life of sufferers, which encompasses chemical and biological processes, their affects, intersectional conflicts, lay concepts of illnesses, informal self-care networks, and unequal access to health services. This ethnography demonstrates that the experience of toxic suffering embodies inequalities in environmental health in the time of the Anthropocene and is shaped by structural vulnerabilities and politics of exposure.

Aim: To analyse and compare the epidemiology of maxillofacial trauma during four months of the lockdown period and compare it with the same months from the previous year (2019 and 2020).

Materials and Method: A retrospective record-based study was conducted with data drawn from all maxillofacial trauma patients who presented in the maxillofacial and oral surgery unit, of the University of Pretoria (UP) and Steve Biko Academic Hospital (SBAH) from April to July of 2019 and April to July of 2020. Data collected included age, gender, aetiology of injury, site of injury, severity and extent of injury, fracture pattern and site, waiting period for treatment and month of injury. Chi-square test was used to evaluate the association between variables. The level of significant was set at p ≤ 0.05.

Results: A total of 197 patients were seen in the two institutions with maxillofacial injuries for the years 2019 and 2020 with ages ranging from 1 to 81 years and a mean of 36.24. Most patients were males 167(85%). Many patients were seen in 2019 at 139(71%). There was no association between the fracture site and the aetiology. The mandible was significantly the most common site of injury and more conservative treatment was done as compared to other forms of treatment (p < 0.05).

Conclusion: More Maxillofacial cases were seen in 2019 than in 2020 with more males as compared to females. The majority of injuries were assaults followed by motor vehicle accidents (MVA). The mandible was the common site of injury. More conservative treatment was done compared to other forms of treatment.

Authors: Mello Fábio Bacelar , Pinto Luiz Fernando Rodrigues
Published: July 2023

La ausencia de planificación urbana adecuada a las ciudades ha generado problemas a la vida urbana, causando ineficiencia de la movilidad urbana, perjudicada como resultado del crecimiento desordenado de la densidad poblacional de las ciudades, generando consecuencias como el aumento de la contaminación, grandes embotellamientos, aumento de los accidentes de tránsito y desigualdades sociales. Por lo tanto, este estudio tiene como objetivo presentar las características de la ciudad de Boa Vista-RR, vinculadas a la planificación urbana y la movilidad, y una propuesta de un sistema de transporte público moderno y compatible con la infraestructura de la ciudad. Para alcanzar este objetivo, se realizó una investigación exploratoria con enfoque cualitativo, con el objetivo de conocer el modelo de sistema de transporte público implantado en la ciudad de Jundiaí, São Paulo, y su compatibilidad con una ciudad de tamaño medio. En cuanto a los procedimientos técnicos, se realizó un estudio de caso, con el objetivo de extraer materiales que retraten la realidad de la movilidad urbana de ambas ciudades. Los resultados de esta investigación indican que el sistema de transporte público implantado en la ciudad de Jundiaí es compatible con la ciudad de Boa Vista, representando una oportunidad para mejorar la calidad de vida de los ciudadanos.
Centers in the Event Domain: A Retake on the Wholeness of Urban Spaces
Authors: Kahraman Ridvan
Published: July 2023

This article demonstrates that geometric analysis by itself is not enough to evaluate Alexander’s wholeness in public spaces and that his theories of wholeness can—and should—be extended into the realm of events. The first section provides a summary of the theory of centers and the relevance of events with regard to the theory of wholeness. In the second section, a new way to classify centers is presented, along with insights from Alexander’s works into an approach for incorporating event centers into the theory of wholeness. The final part puts these ideas to the test on a public square in Stuttgart, Germany, using a geometric analysis and an analysis of user activity to determine the performance of the square as a center. The research concludes that utilizing Alexander’s theories from an event-first rather than a geometry-first perspective is an approach especially well-suited for public spaces.
Omental torsion with multiple congenital anomalies
Authors: MBV Prasad , K Sanjeeva Rao
Published: July 2023

Aim: We report two rare cases with complete omental torsion with right sided inguinal hernia, maldescended testis and Meckel’s diverticulum along with review of literature. Patients: Two patients presenting with acute abdomen and inguinal hernia, diagnosed preoperatively as omental torsion and undescended testis and Meckel’s diverticulum were managed operatively with omentectomy, hernioplasty and orchidectomy. Results: Both patients recovered well postoperatively and have remained asymptomatic. Conclusion: Omental torsion is one of the rare causes of acute abdomen and may mimic various other causes. It is quite often possible to diagnose preoperatively by USG and CT scan abdomen. Symptomatic patients with preoperative diagnosis need omentectomy preferably through laparoscopy. Keywords: Omental torsion; inguinal hernia; maldescended testis; meckel’s diverticulum; laparoscopic omentectomy

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome of pathologic immune activation characterized by clinical signs and symptoms of extreme inflammation. HLH can be challenging to diagnose because the initial symptoms may mimic common infections. People with HLH usually develop symptoms within the first months or years of life which may include fever, enlarged liver or spleen, cytopenia and neurological abnormalities. HLH can only be diagnosed with the proper blood tests. A sample of bone marrow may be obtained to look for hemophagocytosis. Treatment depends on a number of factors, including the severity of symptoms, onset of age, and the underlying cause of the condition. Patients are usually treated with steroids plus chemotherapy and / or an antibody therapy that destroys the T cells. Patients may receive other medications that suppress the immune system. Many patients must also have their immune systems replaced by means of a bone marrow transplant in order to be cured of HLH. We report the brief description of a case along with treatment algorithm. Keywords: cytopenia, hemophagocytosis, hemophagocytic lymphohistiocytosis

The market and distribution of investment products that contribute to the achievement of the Sustainable Development Goals (SDGs), as a paradigm of the 2030 Agenda, are instruments that investors should incorporate into their financial portfolios. This paper analyses investors' preferences for investment funds that contribute in their investment policy to the achievement of SDG 6. Choice experiment methodology has been applied to try to obtain a valuation by Spanish investors. A survey was carried out in which a total of 456 valid observations were obtained. The results show that there is a high valuation of funds whose portfolios include investments that contribute to SDG 6 and that there is also heterogeneity in preferences.
Steady state economic freedom

Published: July 2023

This note projects forward into the distant future the number of countries existing under regimes of different levels of economic liberalism by deriving a transition probability matrix from Economic Freedom of the World data. Naively extrapolating trends from 1970-2020 suggests a modest majority of 165 countries will be economically free in the long-run steady state, with results driven by improvements in variables associated with the freedom to trade internationally and especially the quality of the legal system and property rights.
Gender and job satisfaction in OECD countries
Authors: Kose Tekin , Avcioglu Kubra
Published: July 2023

Gender differences in labour market outcomes are frequently reported. Earlier findings on associations of job satisfaction and gender reveal mixed results. Majority of empirical results indicate that women report higher levels of job satisfaction than men whereas others find no gender differences in job satisfaction. This study explores gender differences in job satisfaction by utilizing the Survey of Adult Skills for OECD countries. Employing the Balanced Worth Vector (BWV) procedure for data analysis, this study contributes to literature by presenting additional cross-national evidence from various regions of the world. Our findings reveal that there are heterogeneities in gender-gap paradox of job satisfaction across OECD countries.
