Ci, Mãe do Mato: o mito das amazonas às avessas em Macunaíma e o projeto modernista
Authors: Redel Elisangela
Published: April 2024

O presente texto divide-se em duas partes: na primeira, trago considerações gerais e introdutórias sobre Mário de Andrade, seu arquivo da criação literária e a assimilação crítica que fez de outros textos, como os do etnólogo alemão Theodor Koch-Grünberg, na elaboração de Macunaíma: o herói sem nenhum caráter (1978).  No segundo momento deste trabalho discuto a representação do mito das amazonas guerreiras no terceiro capítulo da rapsódia, chamado Ci, Mãe do Mato, valendo-me de algumas correspondências, que configuram-se em material auxiliar para a interpretação da obra. Na escrita andradina, o mito das amazonas é descolonizado, porque recebe outros rumos e elementos que distorcem suas características fundantes, ou seja, Mário renega a cópia, ao se apropriar da versão clássica do mito de forma “antropofágica”. Desta perspectiva, Mário empresta à icamiaba brasileira um fundo sexual, carnal e perverso, uma vez que a amazona perde sua característica belicosa e se entrega arrebatadamente aos prazeres do amor junto ao herói. Essa assimilação crítica está inscrita no projeto estético e ideológico modernista, mas também ressoa elementos do Expressionismo alemão, de cuja vanguarda Mário teria sido influenciado no reconhecimento do mito primitivo.
Proust e La Sizeranne: uma rivalidade à luz de cartas e notas de rodapé
Authors: Nogueira Luciana Persice
Published: April 2024

Todo o período da Belle Epoque foi marcado por uma cacofonia de disputas, polêmicas e embates de ordem artístico-intelectual. Marcel Proust, depois do fracasso de seu primeiro título de ficção, encontra no trabalho da tradução de dois livros de John Ruskin uma forma de se projetar e firmar como uma voz de respeito junto a seus pares. Mas isso vai lhe exigir forjar uma rivalidade com outro especialista na obra de Ruskin: o crítico de arte Robert de La Sizeranne.

Leituras, anotações, marcações: o “canteiro de obras” de Giorgio Caproni
Authors: Peterle Patricia
Published: April 2024

O presente trabalho propõe uma reflexão sobre alguns resíduos e vestígios encontrados no arquivo do acervo da biblioteca pessoal do poeta italiano Giorgio Caproni (1912-1990), conservado na Biblioteca Guglielmo Marconi, em Roma. Todo e qualquer arquivo provoca no pesquisador indagações, instiga-o a olhar para os restos, para as margens. Nesse sentido, os rastros das leituras feitas por Caproni apontam para um exercício paralelo à sua própria poética.
Leitura cruzada dos cadernos de Gustave Flaubert e de anotações de Maxime Du Camp da viagem que fizeram juntos para o Oriente
Authors: Ribeiro Lúcia Amaral de Oliveira
Published: April 2024

Neste artigo, trato da gênese de traços do estilo de Flaubert por meio da análise de suas anotações da viagem que fez com Maxime Du Camp para o Oriente, no período de 1849 a 1851, antes de publicar seus romances. A Biblioteca histórica da Cidade de Paris conserva seis dos cadernos que contêm as anotações feitas durante a viagem. Esses cadernos receberam a numeração de 4 a 9. Analiso formas textuais que se repetem nesses cadernos de Flaubert e em manuscritos de Du Camp, que estão na Biblioteca do Instituto da França, em Paris. O objetivo do artigo é trazer elementos para o estudo de como Flaubert se apropria de formas que circulam na literatura da época para construir seu estilo, impregnado de efeitos sensoriais e plásticos.
A cena teatral documentada: identificação arquivística e processos de criação
Authors: Mota Mabel Meira , Severino Ivana Bittencourt dos Santos
Published: April 2024

No âmbito do teatro, a produção do texto/documento advém do imbricamento de diferentes sujeitos produtores cujas intervenções precisam ser consideradas tanto para análise genética quanto para o tratamento arquivístico. No acervo do Bando de Teatro Olodum (BTO), depositado no Nós, Por Exemplo - Centro de Documentação e Memória, localizado no Teatro Vila Velha, em Salvador-BA, verifica-se a existência de dois percursos: o da escritura, próprio à esfera privada da produção do texto teatral; e o da leitura do texto teatral, decorrente da encenação e recepção crítica deste. A partir do escopo teórico da Arquivística e da Crítica Genética, objetiva-se, aqui, apresentar os procedimentos metodológicos adotados para a organização do fundo, dando especial destaque aos processos de criação.  Este trabalho é resultado da aplicação da Identificação, etapa fundamental da metodologia arquivística, advinda da ampliação do campo de ação da Diplomática para os documentos modernos. Através dessa etapa, a partir da qual foram compreendidas as circunstâncias de produção e os usos dos documentos do referido fundo, tornou possível estabelecimento do seu arranjo e descrição, que resultou na elaboração do inventário das séries: produção artística, clipagem, correspondência, material gráfico e diversos.
Expansion du Regiebuch. Refigurations du carnet du mise-en scène dans le théâtre contemporain
Authors: Dries Luk Van den
Published: April 2024

Cette article examinera l'évolution récente du cahier de metteur en scène ou Regiebuch. Le cahier de mise en scène est l'instrument préféré du metteur en scène, ou « l'auteur » théâtral qui s'est développé le long du dramaturge depuis le début du XXe siècle. Traditionnelement le cahier se situe littéralement entre le texte dramatique et la mise en scène. C'est le carnet de croquis du réalisateur qui enregistre ses idées, ses intentions, ses rêves autour d'une production. En même temps, c'est aussi un journal du processus de répétition. Dans les développements du siècle dernier, souvent regroupés comme l'évolution vers un « théâtre des metteur en scènes » (plutôt qu'un théâtre de dramaturges), l'importance du Regiebuch a augmenté de façon spectaculaire. Dans l'histoire de la scène moderne, le texte devient moins important ou même disparaît au profit de l'imaginaire visuel et auditif du réalisateur. Avec l'émergence de nouveaux médias, tels que les enregistrements numériques et les applications informatiques pour l'édition audio et vidéo, la médialité du Regiebuch évolue également. De son statut initial de carnet de croquis et de journal, il se transforme en une sorte de « storyboard ». L'hypothèse de cet article est que la structure narrative, ou plutôt le récit visuel sur scène, est co-dirigé et déterminé par les techniques de composition visuelle utilisées pendant le processus de répétition. Afin d'élaborer et de tester cette théorie, les carnets de Jan Fabre et Romeo Castellucci seront discutés.
Os últimos manuscritos de Onetti e Cuando ya no importe
Authors: Reales Liliana
Published: April 2024

Dos últimos textos escritos pelo uruguaio Juan Carlos Onetti saíra, um ano antes de sua morte, aquele que se considera o seu último livro, Cuando ya no importe, publicado em 1993 pela editora espanhola Alfaguara. Depois de um minucioso trabalho de cotejo entre o livro publicado por Alfaguara, e mais tarde pela editora Galaxia Gutemberg, e os manuscritos que se guardam na Biblioteca Nacional de Montevidéu como sendo os pertencentes a Cuando ya no importe, percebemos que vários papéis que formam esse corpus fragmentário se conservam aparentemente inéditos, não tendo formado parte do mencionado livro, em suas duas edições. Supõe-se, a partir das pesquisas de Daniel Balderston, que Onetti talvez não tenha participado da organização desses últimos papéis por ele escritos e que foram selecionados para compor Cuando ya no importe, cabendo essa tarefa a pessoas de sua família e outras não identificadas. A partir destas constatações, a nossa pesquisa pretende observar as mudanças entre o os manuscritos, os textos datilografados e os publicados, assim como também descrever os manuscritos não incluídos. Para tais objetivos, a equipe de pesquisadores procedeu à digitalização dos manuscritos e à transcrição diplomática dos mesmos.

Gostaria de relatar um dos frutos de uma pesquisa iniciada com os manuscritos do escritor belga Henry Bauchau. Auxiliado por uma equipe de três alunos de graduação em francês da FFLCH-USP, dedicada à transcrição e à tradução da obra, pude interpretar a relação entre criação e escritura no romance Édipo na estrada de Bauchau, percorrendo uma parte dos quatorze cadernos de rascunhos guardados na Biblioteca Real da Bélgica e  das cinco versões mantidas no Acervo Bauchau na Universidade de Louvain-la-Neuve.
Photomultiplier Tubes for Programmable Logic Controller Foreign Object Sorting System and Its Performance Analysis
Authors: Wang Qing , Guo Chunxiang
Published: April 2024

The photoelectric foreign object sorting system is a comprehensive device developed to remove foreign objects from target substances, integrating photoelectric, computer, and mechanical technologies. This system combines photoelectric, computer image, and mechanical technologies to
identify materials based on color and appearance, utilizing the scattered light returned from the scanned object for detection and recognition. This work designs a photoelectric foreign object sorting system for food and tobacco. This system takes photomultiplier tubes as the main photoelectric
devices and a programmable logic controller (PLC) as the control unit. The hardware components of this system include the design of a low-noise preamplifier, conditioning circuit, ADC data acquisition module, and PLC-external circuit connections. In simulation experiments, testing is conducted
on the low-noise preamplifier, considering the significant impact of the collected signals on subsequent analysis. Amplitude-frequency and phase-frequency tests show that the circuit signal output of this module is stable. There are no oscillations in the time domain, and no occurrences of
overshooting or ringing in frequency. The noise indicates that the signal noise of this module is relatively low. During the debugging process, ADA4896 is selected, and a black-and-white alternating stripe with a 3 mm spacing is used as the scanning object. As expected, the first-stage amplification
results of the low-noise preamplifier show a range of 2 mV with some DC components in the output voltage. In its second-stage amplification, the fine scale reaches 10 mV, and the output signal can represent the physical characteristics of the scanned object.
Soil Moisture Information Improves Drought Risk Protection Provided by the USDA Livestock Forage Disaster Program
Authors: Krueger Erik S. , Ochsner Tyson E. , Brorsen B. Wade
Published: April 2024

The USDA Livestock Forage Disaster Program (LFP) offers financial assistance to farmers and ranchers with grazed forage losses caused by fire or drought. Payments for drought losses are based on the U.S. Drought Monitor (USDM), which is designed to integrate meteorological, agricultural, hydrological, ecological, and socioeconomic droughts. Because soil moisture deficit is a more specific measure of agricultural drought, we hypothesized that basing LFP payments on soil moisture observations could better reduce producers’ risk. Therefore, our objectives were to 1) quantify relationships of forage yield with USDM-based LFP payment multipliers and with in situ soil moisture, 2) develop an alternative LFP payment multiplier structure based on in situ soil moisture, and 3) quantify risk reduction using the current and alternative payment structures. We focused on Oklahoma, United States, which has led the nation in LFP payments received and has >25 years of in situ soil moisture observations statewide. Using non-alfalfa hay yield as a surrogate for forage production, we found that LFP payment multiplier values and soil moisture anomaly were each related to yield, and soil moisture anomaly explained 54% of yield variability. However, the USDM-based LFP payment structure sometimes resulted in payments for above-average yield, and higher payments did not always correspond with greater yield losses. We developed an alternative soil-moisture-based payment structure that reduced financial risk by >20% compared with the current USDM-based structure. Our study identifies an improved LFP payment structure for Oklahoma that can be evaluated and refined in other states or nationwide using other soil moisture data sources.
Evaluating Precipitation Events Using GPM IMERG 30-Minute Near-Real-Time Precipitation Estimates
Authors: Sutton Jessica R. P. , Kirschbaum Dalia , Stanley Thomas , Orland Elijah
Published: April 2024

Accurately detecting and estimating precipitation at near–real time (NRT) is of utmost importance for the early detection and monitoring of hydrometeorological hazards. The precipitation product, Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (IMERG), provides NRT 0.1° and 30-min precipitation estimates across the globe with only a 4-h latency. This study was an evaluation of the GPM IMERG version 6 level-3 early run 30-min precipitation product for precipitation events from 2014 through 2020. The purpose of this research was to identify when, where, and why GPM IMERG misidentified and failed to detect precipitation events in California, Nevada, Arizona, and Utah in the United States. Precipitation events were identified based on 15-min precipitation from gauges and 30-min precipitation from the IMERG multisatellite constellation. False-positive and false-negative precipitation events were identified and analyzed to determine their characteristics. Precipitation events identified by gauges had longer duration and had higher cumulative precipitation than those identified by GPM IMERG. GPM IMERG had many false event detections during the summer months, suggesting possible virga event detection, which is when precipitation falls from a cloud but evaporates before it reaches the ground. The frequency and timing of the merged passive microwave (PMW) product and forward propagation were responsible for IMERG overestimating cumulative precipitation during some precipitation events and underestimating others. This work can inform experts that are using the GPM IMERG NRT product to be mindful of situations where GPM IMERG–estimated precipitation events may not fully resolve the hydrometeorological conditions driving these hazards.

Significance Statement

Accurately estimating rainfall to detect and monitor a precipitation event at near–real time is of utmost importance for hydrometeorological hazards. We used a state-of-the-art rainfall estimation product called GPM IMERG that uses infrared and passive microwave measurements collected from a constellation of satellites to produce near-real-time rainfall estimates every 30 min worldwide. The purpose of our research was to identify when, where, and why GPM IMERG falsely detected and missed precipitation events. Our results suggest that the frequency and timing of passive microwave precipitation with forward propagation were responsible for IMERG missing events, overestimating total rainfall during some precipitation events, and underestimating total rainfall in other precipitation events. Our future work will further investigate precipitation events using the GPM IMERG version 7 near-real-time product.
Multivariate Multinomial Logit Models with Associations among Dependent Variables
Authors: Yamaguchi Kazuo , Zhou Jesse
Published: April 2024

The authors introduce a new group of multinomial logit models with special contrasts to identify covariate effects on multiple categorical dependent variables that are strongly associated with each other. The authors first develop the method for a case with two dependent variables and then extend the method to a case with three dependent variables. The model can account for both nominal and ordinal scales of categorical dependent variables. The authors formulate the covariate effects to represent unique effects on each dependent variable so that they become independent across different dependent variables. The application focuses on the multiplicity of occupational attainments by analyzing how gender, race, educational attainment, and parental occupation characteristics affect three distinct but nonindependent dimensions of occupations: socioeconomic status, social skill level, and math and science skill levels.
A Novel Ex Vivo Blinking Method for Comparing the Corneal Residence Time of New Shampoo Formulations
Authors: Glaudo Markus , Urbach Marc , Panfil Claudia , Herkert Stephanie , Brown Mark , Schrage Norbert
Published: April 2024

In the cosmetics sector, many products such as shampoos have a probability of accidental ocular exposure during their routine use. One very specific safety parameter is the residence time of the substance on the corneal surface, as prolonged exposure may cause injury. In this study, we developed a system that simulates corneal exposure to blinking and tear flow, for comparing the corneal clearance times of viscous detergent formulations. The Ex Vivo Eye Irritation Test (EVEIT), which uses corneal explants from discarded rabbit eyes from an abattoir, was used as the basis for the new system. To simulate blinking, we developed a silicone wiping membrane to regularly move across the corneal surface, under conditions of constant addition and aspiration of fluid, to mimic tear flow. Six shampoo formulations were tested and were shown to differ widely in their corneal clearance time. Three groups could be identified according to the observed clearance times (fast, intermediate and slow); the reference shampoo had the shortest clearance time of all tested formulations. With this new system, it is now possible to investigate an important physicochemical parameter, i.e. corneal clearance time, for the consideration of ocular safety during the development of novel cosmetic formulations.
Psychedelics and the ‘inner healer’: Myth or mechanism?
Authors: Peill Joseph , Marguilho Miriam , Erritzoe David , Barba Tommaso , Greenway Kyle T , Rosas Fernando , Timmermann Christopher , Carhart-Harris Robin
Published: April 2024

Background:

Reference to an intrinsic healing mechanism or an ‘inner healer’ is commonplace amongst psychedelic drug-using cultures. The ‘inner healer’ refers to the belief that psychedelic compounds, plants or concoctions have an intrinsically regenerative action on the mind and brain, analogous to intrinsic healing mechanisms within the physical body, for example, after sickness or injury.

Aims:

Here, we sought to test and critique this idea by devising a single subjective rating item pertaining to perceived ‘inner healing’ effects.

Methods:

The item was issued to 59 patients after a single high (25 mg, n = 30) or ‘placebo’ (1 mg, n = 29) dose of psilocybin in a double-blind randomised controlled trial of psilocybin for depression.

Results:

Inner healer scores were higher after the high versus placebo dose of psilocybin ( t = 3.88, p < 0.001). Within the high-dose sub-sample only, inner healer scores predicted improved depressive symptomatology at 2 weeks post-dosing.

Conclusions:

The principle of activating inner healing mechanisms via psychedelics is scientifically nascent; however, this study takes a positivist and pragmatic step forward, asking whether it warrants further examination.
Feasibility of Remote Coaching With Early Interventionists: NDBI Strategies in Part C
Authors: Tomeny Kimberly R. , Tomeny Theodore S. , McWilliam R. A.
Published: April 2024

Early intervention supports infants and toddlers with confirmed or suspected autism spectrum disorder (ASD) in achieving optimal outcomes, and caregiver-implemented NDBIs are recommended as a developmentally appropriate intervention approach for very young children and their families. Research highlights discrepancies between early interventionists’ perceptions of their practices and their observed practices, possibly contributing to implementation gaps. Remote coaching is a viable method of supporting early childhood professionals’ use of recommended practices, yet limited research has examined remote coaching with early interventionists in community systems (e.g., Part C). The current feasibility study explored differences between U.S. early interventionists’ reported and observed practices and compared bug-in-ear versus video review coaching methods with early interventionists working with families of toddlers with confirmed or suspected ASD. Results demonstrated (a) early interventionists reported higher quality practices than observed, and (b) remote coaching is a community-viable professional development approach in supporting early interventionists’ use of recommended practices.
Intraventricular haemorrhage treated by extra ventricular drainage with catheter mistakenly penetrating the cisterna ambiens: A case report
Authors: Gao Liansheng , Yu Kaibo , Feng Yanfei , Yan Feng , Qian Cong
Published: April 2024

Intraventricular haemorrhage (IVH) is a severe and acute type of stroke with a complex pathophysiology and is a therapeutic challenge. This case report described a man in his early 50’s diagnosed with IVH by computed tomography (CT). Although bilateral extraventricular drainage (EVD) was undertaken, a postoperative CT scan showed that while the left catheter was correctly positioned, the right catheter had been wrongly inserted into the cisterna ambiens. The procedure was equivalent to simultaneous EVD combined with cisternostomy. As a consequence, the haematoma was rapidly removed, the risk of infection and long-term hydrocephalus was reduced, and prognosis was improved. Large case-control studies or prospective studies are needed to evaluate the safety and effectiveness of this treatment modality.
Multiple carcinomas in a woman with HIV infection: a case report and literature review

Published: April 2024

Non-acquired immunodeficiency syndrome-defining cancers (NADCs) are malignancies in persons living with human immunodeficiency virus (PLWHIV) and are not primarily due to the host’s immunodeficiency. There is renewed clinical interest in long-term morbidities in PLWHIV as well as malignancies that occur in this population. We herein describe a 36-year-old woman with a 2-year history of an anal wound and right breast mass. She had been diagnosed with HIV infection prior to the development of these lesions. Clinical and laboratory evaluations led to diagnoses of breast and anal cancers. Chemotherapy and antiretroviral therapy were begun, but the patient discontinued these treatments early and was lost to follow-up. NADCs will continue to be a major clinical issue as the global population ages. This presentation of two NADCs (breast and anal cancers) in a PLWHIV further highlights the burden of multiple malignancies on the depleted health of HIV-infected patients. Early identification and treatment of HIV upon patients’ presentation to cancer care sites and screening for NADCs at HIV/AIDS care sites are recommended for improved outcomes.
Modeling study on the mechanical performance of CFRP/Al single-lap rivet joints under hygrothermal environmental conditions
Authors: Zhang Shiguang , Qin Xuda , Li Shipeng , Li Hao , Xu Yanwei , Guoyu Fu
Published: April 2024

Carbon Fiber Reinforced Polymers (CFRP) and aluminum alloys, owing to their exceptional mechanical properties and lightweight attributes, are extensively used in aircraft manufacturing. However, prolonged exposure to a hygrothermal environment can compromise the mechanical integrity of composite joint structures. In this paper, accelerated aging experiments were designed to test the mechanical properties of CFRP after hygrothermal aging, a novel mechanical property prediction model tailored for the hygrothermal coupled environment is presented. The model accurately predicts the modulus and strength of CFRP after hydrothermal aging. A three-dimensional finite element model for the CFRP interference riveted structure, considering a tri-coupled state of moisture, temperature, and force was established by the application of subroutine and field superposition. The precision of this finite element model has been affirmed through accelerated aging tests. By integrating finite element analysis with experimental methods, this research delves into the failure modes and mechanisms of CFRP and its joints under hygrothermal conditions. It was discerned that the hygrothermal environment undermines the bond between fibers and the matrix, resulting in pronounced interlaminar delamination and shear failure in CFRP. The failure forms gradually change from “flaky” at lower levels of aging to “filamentary” at higher levels of aging. For CFRP riveted structures, the hygrothermal conditions influence their loadbearing capability and shift the primary positions of failure.
Easy to read, easy to judge: Assessing readability as a heuristic for credibility in news
Authors: Sparks Jessica F. , Waddell T. Franklin
Published: April 2024

Despite calls for journalists and media agencies to address a disconnect between news audiences and news prose, content continues to increase in its difficulty to read and comprehend for the masses. While readability is often associated with audience comprehension and engagement, studies have neglected to assess whether readability is a factor in audience assessments of the credibility of content. Using an online experimental design, this study examines whether readability acts as a heuristic that helps news consumers make credibility judgments of news. Results show that readability tends not to be a predictor of credibility perception, regardless of partisanship strength or media use preferences. Theoretical and practical implications are discussed.
Intimate Partner Violence During Lockdown: The Potent Influence of Stress and Authoritarian Beliefs
Authors: Bonneterre Solenne , Zerhouni Oulmann , Lepage Johan
Published: April 2024

COVID-19 pandemic caused several lockdowns in most countries, enclosing together perpetrators and victims of intimate partner violence (IPV). Our study investigates psychological mechanisms associated with IPV. We supposed that stress provoked by the pandemic, as well as adhering to authoritarian beliefs will be a predictor of IPV. Using an online questionnaire, 1,659 individuals indicated whether they had been victim or witnessed IPV at home and filled a perceived stress scale, anxiety, depression, and aggressiveness scales. They were also asked to fill an authoritarianism scale, how they cope with the lockdown situations, and some demographical information. We found that individuals who were victims or witnesses of IPV during the COVID-19 lockdowns tended to have more difficulty isolating at home or to hold stronger authoritarian beliefs. Importantly, the association between authoritarian beliefs and IPV was moderated by perceived stress, suggesting that individuals who hold authoritarian views may be more affected by stress, which could increase the risk of experiencing or witnessing IPV. IPV incidents during the pandemic lockdowns may be partially explained by perceived stress, which is amplified by authoritarian attitudes. Further discussions on the causes of IPV and interventions are suggested.
Bio-based epoxy and unsaturated polyester resins: Research and market overview
Authors: Baron Christian , Donadio Federica , Scherdel Michael , Taha Iman
Published: April 2024

The presented study provides an overview of the current research achievements and the emerging market of bio-based thermosetting polymers. Environmental attributes related to bio-based polymers trigger a steadily growing interest in this novel and promising field. Due to their importance among thermosets in terms of composite applications and quantity, this review focusses on epoxy and unsaturated polyester resins. Current studies are mainly concerned with alternative renewable raw materials to substitute fossil content and their synthesis to improve their end-properties. A common target is the increase of bio-based content within the cured resin. In spite of today’s efforts in research, the recent market review reveals only few commercially available bio-based thermosetting resin systems. However, they are commonly suited for a broad variety of processing methods and applications with bio-contents up to 75%.
Cold metal transfer-based wire arc additive manufacturing of pure copper with ultra high tensile strength
Authors: Tomar Bunty , Sekar Shiva
Published: April 2024

Copper is used in various heating and cooling applications by exploiting its excellent thermal and electrical conductivities. Powder- and laser-based additive manufacturing (AM) of pure copper is challenging as it encounters porosity because of its low absorptivity. The present research reports the feasibility of cold metal transfer-based wire arc additive manufacturing (CMT-WAAM) for the manufacturing of pure copper thin wall. The microstructure of the deposit is examined at three distinct locations. The mechanical properties (including ultimate tensile strength, yield strength, elongation and hardness) are examined in both scanning direction (SD) and build direction (BD). The thermal and electrical properties of the deposit are also measured. The deposited thin wall is reported to be firm and straight without any bulging and collapsing. The CMT-WAAM fabricated pure Cu samples exhibit superior tensile strength (310 ± 12 MPa in SD and 265 ± 9 in BD) than all other AM techniques. The thermal and electrical conductivities of the built copper wall are comparable to the previously reported conductivities of pure copper fabricated by other AM routes.
The case for a climate bonus: waste pickers’ perceptions of climate change in Minas Gerais
Authors: Dias Sonia Maria , Castán Broto Vanesa , Cypriano Breno , Ogando Ana Carolina , Gonçalves Juliana
Published: April 2024

While the work of waste pickers advances urban sustainability, there has been little focus on how climate change impacts affect them. This paper reports on a pilot study with 61 waste pickers in Minas Gerais, Brazil to understand their perspectives on climate change impacts and actions. It explores how waste pickers experience climate change impacts at home and at work, their adaptive strategies and the specific actions and actors needed to address these impacts.

Waste pickers have practical knowledge and experience of climate events. But due to precarious employment and lack of access to services, infrastructure and social support, their responses are improvised and inefficient. They require better institutional support and their proposals must be incorporated into a negotiated approach to urban resilience. Proposals such as the climate bonus – similar to the existing recycling bonus – may help address the structural drivers of vulnerability for waste pickers in Minas Gerais.
HPV-associated oropharyngeal carcinomas in patients living with HIV on long-term antiretroviral therapy: Case reports
Authors: Yancheva-Petrova Nina , Grozdeva Rusina , Ivanov Daniel , Strashimirov Dimitar
Published: April 2024

In the 1970s, human papillomaviruses (HPV) were ascertained as the aetiologic agents of cervical carcinoma. Subsequently, an association with HPV was established in other epithelial tumours, including squamous cell carcinoma of the head and neck (HNSCC). HPV has demonstrated a high potential for inducing oropharyngeal tumours, with HPV-16 infection posing a significant oncogenic risk. People living with HIV (PLWH) are identified as being at a higher risk of HPV infection and the subsequent development of HPV-associated tumours of the oropharynx. We present two patients under the care of the Department of AIDS with long-term HIV infections who were newly diagnosed with HPV-associated carcinomas of the tonsils. Both patients had been on antiretroviral therapy (ART) for over 15 years, achieving optimal viral suppression for more than 10 years. Chemotherapy and radiation therapy were employed in the treatment of the carcinomas. Throughout the neoplastic disease treatment, both patients maintained optimal viral suppression for HIV. The presented cases underscore the fact that despite achieving long-term optimal viral suppression of HIV, people living with HIV remain susceptible to the development of HPV-associated neoplasms.
Nebulised pentamidine prophylaxis of pneumocystis pneumonia in adults accessing HIV services at royal free hospital, London
Authors: Bergstrom Malin , Rahim Anika , Akodu Jane , Marshall Gavin , Harrison Cora , Penrose Louisa , Lipman Marc CI , Miller Robert F
Published: April 2024

Receipt of nebulised pentamidine in people with HIV was audited to identify if individuals were appropriately receiving nebulised pentamidine, and whether national guidelines were being followed when prophylaxis was commenced and discontinued. Of 76 people with who received nebulised pentamidine, the main indication for starting nebulised pentamidine was a co-trimoxazole adverse drug reaction. Co-trimoxazole desensitization was not attempted before starting nebulised pentamidine. The main indication for stopping nebulised pentamidine prophylaxis was when immune reconstitution occurred. This single centre audit revealed that national guidelines were being followed in most cases. The lack of information regarding the reason for starting or stopping nebulised pentamidine prophylaxis, or detail of the clinician’s concerns about potential poor adherence with oral regimens of prophylaxis as a reason for choosing nebulised pentamidine prophylaxis, identifies a need for improved documentation of clinicians’ decision-making. Introduction of pharmacist-led interventions/alerts using patients’ electronic records, similar to those used in primary care, would enable the specialist pharmacy team to identify when and if co-trimoxazole desensitization has been offered and discussed/declined before a clinician prescribes nebulised pentamidine as well as enabling identification of those in who pentamidine prophylaxis has been continued, despite “immune reconstitution”.
Total ankle replacement versus ankle fusion for end-stage ankle arthritis: A meta-analysis
Authors: Li Taiyi , Zhao Li , Liu Yan , Huang Li , Zhu Jin , Xiong Jie , Pang Junfeng , Qin Lina , Huang Zonggui , Xu Yinglong , Dai Hai
Published: April 2024

Purpose

This study aims to systematically review the efficacy and safety of total ankle replacement (TAR) and ankle fusion (AF) as treatment options for end-stage ankle arthritis.

Methods

A comprehensive literature search was conducted on data from multiple databases, including PubMed, The Cochrane Library, Construction and Building Materials, Embase, Web of Science, and Scopus for RCTs and prospective cohort studies comparing TAR and AF in patients with end-stage ankle arthritis from inception up to June, 2023. Our primary outcomes of interest included patients’ clinical function scores and complications. We employed Review Manager 5.4 and Stata/MP 14.0 software for the meta-analysis.

Results

Our analysis incorporated 13 comparative studies, including 11 prospective studies, one pilot RCT, and one RCT. The pooled results revealed no significant difference in postoperative Short Form-36 scores between the TAR and AF groups (MD = −1.19, 95% CI: −3.89 to 1.50, p = .39). However, the postoperative Foot and Ankle Ability Measure scores in the AF group were significantly higher than in the TAR group (MD = 8.30, 95% CI: 1.01–15.60, p = .03). There was no significant difference in postoperative complication rates between the TAR and AF groups (RR = 0.95, 95% CI: 0.59 to 1.54, p = .85).

Conclusion

Currently available evidence suggests no significant disparity in postoperative outcomes between TAR and AF. In the short term, TAR demonstrates better clinical scores than AF and lower complication rates. Conversely, in the long term, AF exhibits superior clinical scores and lower complication rates, although this difference is not statistically significant.
How to Support Parent-Educators Homeschooling by Open Projects? A Case Study of Two Families Developing Strategic Knowledge
Authors: Tremblay-Wragg Émilie , Viola Sylvie , Vincent Cynthia
Published: April 2024

The COVID-19 pandemic allowed several parents to immerse themselves into homeschooling. In the province of Quebec (Canada), homeschooling is on the rise, increasing from 6,000 children in 2019 to 14,000 in 2021. While integrating learning objectives prescribed by current educational curriculum, parents who act as educators also wish to prioritize pedagogical strategies that are congruent with their preferences and values, such as undertaking open projects involving the whole family. However, these parents face challenges in linking learning goals with their projects. As a result, they require support with project design, among other things, through effective planning, autoregulation, and evaluation mechanisms. Therefore, a study involved six novice families who started homeschooling because of the pandemic impact on the provincial school system. Interviews were conducted with the parent-educators before and after providing them with pedagogical support over a 12-week period, during which a metacognitive guide served as a modelling tool. Our findings reveal that continued support is crucial, particularly for two mother-educators who developed strategic knowledge that set them apart from the other participants. This exploratory study motivates further research on homeschooling, given the renewed interest in this form of education and the need to ensure quality education for all children.

In theory, discretionary pricing enhances company performance by enabling managers to incorporate local information. However, in practice, managers may be prone to behavioral biases that can lead to suboptimal decisions. This paper investigates the effectiveness of discretionary pricing and behavioral elements on pricing decisions via field and lab experiments. Collaborating with a pharmacy chain retailer, we first analyzed a field experiment that delegated pricing authority to store managers. We find that managers began engaging in discretionary pricing after two months of experiment implementation and tended to raise the prices of high-priced drugs, resulting in significant sales and revenue losses. This effect was particularly prominent among less-experienced managers and in low-competition stores. We further designed a set of lab experiments to generalize our field observations and explore possible behavioral drivers. We requested lab participants to make pricing decisions under different information display scenarios and compared the average price adjustments between the direct display and click-to-view designs. We observe that participants also tended to raise product prices, and the magnitude of elevation was higher in the click-to-view group where the demand function information is less salient and accessible. Follow-up lab experiments support our field observations, suggesting that experience through repeated decisions and real-time feedback could alleviate the bias effect. Additionally, participants focused on high-priced products when given a list of items for discretionary pricing. Our results highlight the need to consider behavioral biases in human–algorithm collaborations and provide practical insights for improving information provision and training in discretionary settings.
Equity in Health and Humanitarian Logistics: A People-Centered Perspective

Diversity, equity, and inclusion are at the core of present-day health and humanitarian logistics. Aid organizations advocate inclusive people-centered approaches to ensure that affected communities receive appropriate aid in an effective and equitable way. Tensions and even conflicts can arise if affected communities perceive the distribution of aid as inequitable. These perceptions are driven by people’s so-called distributional preferences. These preferences are shaped by culture, social bonds, and experiences, and they describe how an individual’s well-being and behavior are impacted by potential inequalities. Their importance is increasingly recognized by aid organizations, but research on equity in health and humanitarian logistics remains focused on equal access and prioritizing needs. Using current examples from the Syrian and Rohingya refugee crises, we show the importance of recognizing and managing distributional preferences. Based on these examples and in line with diversity, equity, and inclusion principles, we discuss several ways that we, as the operations community, can help conceptualize inclusive and people-centered approaches that account for distributional preferences.
What Makes a Business Model Sustainable? Activities, Design Themes, and Value Functions

Published: April 2024

What makes a business model sustainable? To answer this question, we conducted a systematic review of 390 journal articles on business models for sustainability (BMfS). Building on the activity system perspective, we engaged in an active categorization process, in which we identified 26 activity groups focused on 12 design themes. These activities and design themes are associated with organizations’ potential to use their business models to contribute to sustainable value creation. Our analysis also revealed that the identified activities and design themes can be related to three overarching value functions of BMfS: maintaining, unlocking, and sharing value. Our findings indicate that these value functions play a pivotal role in creating sustainable value through business models. The identified design themes can serve as guiding principles for organizations seeking to make their business models sustainable, while the identified value functions can provide a foundation for theorizing on sustainable value creation through business models.

Although vaccine behaviors differ greatly by gender and age, few studies have examined vaccination at the intersection of gender and age within the Black community. We examined COVID-19 vaccination by gender and age using a survey of over 500 Black adults in Chicago, Illinois, fielded from September 2021 to March 2022. Although 54% had received at least one COVID-19 vaccine, the proportion vaccinated was considerably lower for Black men (28%) and women (37%) under 40 years old than Black men (92%) and women (86%) over 40 years ( p < .001). Concern about vaccine side effects was the most reported barrier for unvaccinated women (56%) and men (38%) under 40 years. Our results suggest that targeted efforts to improve COVID-19 vaccine uptake in the Black community in Chicago after the initial rollout should have focused on young adults, particularly young Black men, with emphasis on addressing concern about vaccine side effects.
Customer Engagement in Utilitarian vs. Hedonic Service Contexts

In the last decade, customer engagement has become a key concept in service research. While the customer engagement literature has gained significant traction and is maturing, studies have predominantly focused on hedonic consumption contexts, such as social media platforms or brand communities. We argue that hedonic and utilitarian service services are fundamentally different. Therefore, existing research knowledge on customer engagement does not necessarily hold in more utilitarian contexts, such as healthcare or financial services, where greater customer engagement could increase societal and individual well-being. By synthesizing insights from the customer engagement literature and the literature on hedonic versus utilitarian consumption, we identify assumptions in customer engagement research that need revising. We extract five fundamental features that differ between hedonic and utilitarian services (affectivity, motivational focus, perception of necessity, role of risk, and relational focus). Based on these features, we derive propositions that describe the role of context for the drivers and outcomes of customer engagement, as well as their interrelationships, and provide guidelines for future research to augment the scope of customer engagement research. As its main contribution, this article problematizes the current premises of customer engagement research and demonstrates that assumptions held about customer engagement are not necessarily generalizable across contexts.

Published: April 2024

Post-Traumatic Growth (PTG) is associated with good cardiovascular health, but the mechanisms of this are poorly understood. This cross-sectional analysis assessed whether factors of PTG (Appreciation of Life (AOL), New Possibilities (NP), Personal Strength (PS), Relating to Others (RTO) and Spiritual Change (SC)) are associated with cardiovascular health in a cohort of 1006 male UK military personnel (median age 34). The findings suggest AOL, PS and RTO are associated with better cardiovascular health through cardiometabolic effects (lower levels of triglycerides, and total cholesterol) and haemodynamic functioning (lower diastolic blood pressure), but not inflammation. However, NP and SC were associated with poorer cardiovascular health through cardiometabolic effects (lower levels of high-density lipoproteins and higher levels of total cholesterol) and AOL had a non-linear association with low-density lipoproteins. These findings suggest that the relationship between PTG and cardiovascular functioning is complex and in need of further scrutiny.
