Published: June 2022

Background

Asthma is one of the most common chronic illnesses among children and adolescents. It can severely affect their quality of life (QoL). Our study assessed the QoL and analyzed potential risk factors for poor QoL among asthmatic children and adolescents.

Methods

This was a cross-sectional comparative study. Pediatric Asthma Quality of Life Questionnaire (PAQLQ) was used to measure the QoL and Asthma Control Test (ACT) was used to evaluate asthma control. The Chi-square test and independent t-test were used to compare variables. We used Multivariate logistic regression to identify the association between determinants and outcomes. Statistical significance was set at p<0.05.

Results

We recruited 132 participants. We found that 47 patients (35.6%) had controlled Asthma and 85 patients (64.3%) had uncontrolled Asthma. When compared to uncontrolled asthma individuals, participants with controlled asthma had improved QoL and scored significantly higher in the symptom domain (P = 0.002), activity domain (P = 0.004), emotional domain (P = 0.002), and overall PAQoL scores (P = 0.002). Hospital admission affects significantly all domains of PAQOL (P<0.05). Poor QoL was significantly associated with hospitalization for asthma (OR = 3.4; CI: 2.77–3.94,P = 0.01), disease severity (OR = 3.0; CI: 2.41–3.61,P = 0.01), uncontrolled asthma (OR = 2.88; CI: 2.21–3.41,P = 0.019), and male gender (OR = 2.55; CI: 1.88–2.91,P = 0.02).

Conclusions

The results of the present study showed that in children and adolescents, uncontrolled asthma, disease severity, and previously hospitalized patients were associated with poor QoL. These factors must be considered when planning a comprehensive care plan for a better quality of life.

Background

To investigate the effects of B1-shimming and radiofrequency (RF) parallel transmission (pTX) on the visualization and quantification of the degree of stenosis in a coronary artery phantom using 7 Tesla (7 T) magnetic resonance imaging (MRI).

Methods

Stenosis phantoms with different grades of stenosis (0%, 20%, 40%, 60%, 80%, and 100%; 5 mm inner vessel diameter) were produced using 3D printing (clear resin). Phantoms were imaged with four different concentrations of diluted Gd-DOTA representing established arterial concentrations after intravenous injection in humans. Samples were centrally positioned in a thorax phantom of 30 cm diameter filled with a custom-made liquid featuring dielectric properties of muscle tissue. MRI was performed on a 7 T whole-body system. 2D-gradient-echo sequences were acquired with an 8-channel transmit 16-channel receive (8 Tx / 16 Rx) cardiac array prototype coil with and without pTX mode. Measurements were compared to those obtained with identical scan parameters using a commercially available 1 Tx / 16 Rx single transmit coil (sTX). To assess reproducibility, measurements (n = 15) were repeated at different horizontal angles with respect to the B0-field.

Results

B1-shimming and pTX markedly improved flip angle homogeneity across the thorax phantom yielding a distinctly increased signal-to-noise ratio (SNR) averaged over a whole slice relative to non-manipulated RF fields. Images without B1-shimming showed shading artifacts due to local B1+-field inhomogeneities, which hampered stenosis quantification in severe cases. In contrast, B1-shimming and pTX provided superior image homogeneity. Compared with a conventional sTX coil higher grade stenoses (60% and 80%) were graded significantly (p<0.01) more precise. Mild to moderate grade stenoses did not show significant differences. Overall, SNR was distinctly higher with B1-shimming and pTX than with the conventional sTX coil (inside the stenosis phantoms 14%, outside the phantoms 32%). Both full and half concentration (10.2 mM and 5.1 mM) of a conventional Gd-DOTA dose for humans were equally suitable for stenosis evaluation in this phantom study.

Conclusions

B1-shimming and pTX at 7 T can distinctly improve image homogeneity and therefore provide considerably more accurate MR image analysis, which is beneficial for imaging of small vessel structures.

Published: June 2022

Contemporary conditions of the functioning of enterprises mean that they are increasingly looking for opportunities to improve organizational performance in strategic management. Scientists are looking for optimal solutions, an appropriate combination of assets and resources, so the debate in the field of strategic orientations is still valid and gaining in importance. Several studies have explored the construct of market orientation, but few include technological orientation with the moderating effects of company assets. In the era of the highly competitive technology market, the area of technological business service providers are particularly interesting, but still undiscovered. This paper examines the effects of market orientation and technological orientation on organizational performance with the inclusion of organizational culture and human resources as moderators. Using questionnaire responses from technological business service providers (n = 689), a regression analysis was conducted to confirm the hypotheses. The results established evidence of positive relationships between market orientation—organizational performance and technological orientation—organizational performance, although in technological firms, the market orientation had a stronger correlation with organizational performance than the technological orientation. Moreover, the organizational culture and human resources play a moderating role in the relationships of market orientation—organizational performance and technological orientation—organizational performance, while weak human resources management weakens relationships market orientation—organizational performance and technological orientation—organizational performance and strong organizational culture reduce the effect of market orientation on organizational performance, significantly reducing the effect of technological orientation on firm performance.

Published: June 2022

The most common major adverse event of endoscopic mucosal resection (EMR) is clinically significant post-EMR bleeding (CSPEB), with an incidence of 6%–7% in large lesions. Repeat colonoscopy, blood transfusions, or other interventions are often needed. The associated direct costs are much higher than those of an uncomplicated EMR. In this review, we discuss the aspects related to CSPEB of large nonpedunculated polyps, such as risk factors, predictive models, and prophylactic measures, and we highlight evidence for preventive treatment options and explore new methods for bleeding prophylaxis. We also provide recommendations for steps that can be taken before, during, and after EMR to minimize bleeding risk. Finally, this review proposes future directions to reduce CSPEB incidence.

Authors: Lee Hany , Kim Soo-Hyeon , Bae Min-Kyung
Published: June 2022

A captive female capybara (Hydrochoerus hydrochaeris) of unknown age discharged a bloody mass from the vaginal region. A histopathology examination revealed the mass to be a reproductive leiomyosarcoma, and an ovariohysterectomy was performed. The histopathology examination confirmed that the excised tissue was a uterine leiomyosarcoma. The purpose of this report is to describe clinical history and histopathological diagnosis of leiomyosarcoma in capybaras. This report is novel because it describes the first diagnosis of uterine leiomyosarcoma in a capybara. Since clinical data about capybaras are rare, this case report will help to diagnosis and treat reproductive diseases of this species.

Published: June 2022

This study investigated dexamethasone (DXM) residues in the milk from intramuscularly dosed dairy cows and established the withdrawal time (WT) of DXM in milk. Eighteen healthy Holstein cows were injected with 20 (DXM-1) or 40 mL (DXM-2) of a drug containing 1 mg/mL of DXM. After administering DXM, milk samples were collected from all cows at 12-hour intervals for five days. The DXM residue concentrations in milk were determined by liquid chromatography-mass spectrometry/mass spectrometry. The correlation coefficient of the calibration curve was 0.9966, and the limits of detection and quantification (LOQ) were 0.03 and 0.1 μg/kg, respectively. The recoveries were 97.0% to 104.0%, and the coefficient of variations was less than 7.22%. After treatment, DXM in DXM-1 was detected above the LOQ in two milk samples at 36 hours and below the LOQ in all milk samples of DXM-2 at 48 hours. Using the WT calculation program WT 1.4, the withdrawal periods of DXM-1 and DXM-2 in milk were established to be two days. In conclusion, the developed analytical method is sensitive and reliable for detecting DXM in milk. The estimated WT of DXM in bovine milk is shorter than the current milk WT recommendation of three days for DXM in lactating dairy cows.

Interrelación entre la deserción escolar y las condiciones socioeconómicas de las familias: el caso de la ciudad de Cúcuta (Colombia)
Authors: Ramírez Zambrano Jorge Raúl , Manzano López Dennys Jazmín
Published: June 2022

El presente artículo establece las conexiones entre la educación y el desarrollo adoptando el enfoque de las capacidades planteado por Amartya Sen. La educación es un medio que posibilita la movilidad social y permite superar las situaciones de pobreza y desigualdad, además auspicia la formación ciudadana y fomenta el debate público, permitiéndole a la ciudadanía influir en el manejo de la sociedad y mejorar la calidad de vida. La investigación plantea la idea de que la condición socioeconómica de las familias es quizás el principal factor que determina la deserción escolar en el ciclo secundario en la ciudad de Cúcuta. Para establecer el grado de influencia, se analiza la situación de la deserción dentro del sistema educativo nacional, departamental y municipal, haciendo uso de las estadísticas manejadas por el Ministerio de Educación Nacional (MEN); seguidamente, se identifican las características de los desertores y sus familias; de igual manera se plantea un modelo econométrico que permite observar las interrelaciones e incidencia de las variables sobre el objeto de estudio. Finalmente se establecen algunas conclusiones y recomendaciones.

Published: June 2022

Este documento presenta la valoración económica que realizan los turistas que visitan las playas de la ciudad de Santa Marta, con base cálculos de modelos econométricos, aplicando el método de costo de viaje; el cual es empleado para estimar valores de uso económicos de ecosistemas. La investigación revela que el costo promedio diario en las bahías es de $42.969,67. Además se encontró que el 47% de los turistas consideran que se debe erradicar de la bahía el vertimiento de aguas lluvias, factor que redunda en una reducción del 8,4% de las visitas a dicha playa. El tiempo de permanencia en las playas resultó altamente significativo para el número de visitas. Los ingresos de los visitantes no son independientes del nivel de educación, sin embargo, no resultó significativo el efecto sustitución.
La caperucita roja y el lobo feroz disfrazado de abuelita: el desarrollo y la economía ortodoxa en el ropaje del neoinstitucionalismo
Authors: Tobón Berrio Luz Estela
Published: June 2022

Pensar el desarrollo como objetivo universalmente deseable ha conducido a la construcción de un debate acerca de cuál es el camino más rápido y eficiente para alcanzarlo, lo que ha representado una tensión dialéctica entre la economía ortodoxa y la economía heterodoxa. Resultado de la experiencia de los países industrializados se han elaborado “recetas para el desarrollo”, consideradas válidas universalmente e impuestas a los países en vías de desarrollo. Empero, el fracaso de estas en los nuevos territorios ha demostrado que el desarrollo no es un proceso homogéneo, objetivo. Por el contrario, la experiencia en las latitudes del “tercer mundo” y la actual crisis económica mundial ha evidenciado que lograr el desarrollo conlleva a la conjunción de fenómenos sociales complejos, comprensibles solo a través de la interdisciplinaridad, donde las instituciones juegan el rol de estructura comunicante entre las diversas disciplinas científicas.

This study was made based on the phenomenon that occurs in PT Dankos Farma that a high turnover rate  encounter the company based on the data between March 2017 to March 2018. This study aims to determine and analyze the influence of job stress and working environment on employee’s turnover intention through job satisfaction as a mediator in pharmacy company in Indonesia, namely PT Dankos Farma. Job satisfaction was chosen as the mediator as it is the primary determinant of turnover intention (Mobley et al., 1979) This study uses data sources from primary data through the distribution of research questionnaires, and secondary data through journals, books, and relevant data obtained from the company. This study uses a non-probability sampling approach, more specifically the purposive sampling through the distribution of questionnaires to 119 respondents of PT Dankos Farma employees. The data analysis technique used in this study is Hierarchical Regression with IBM SPSS 23 application to find out the validity test, reliability test, classic assumption test, t test, F test, coefficient of determination test, and sobel test to find out the mediation effect. Analysis of the statistical testing result showed that job stress had significant negative effect on job satisfaction, and had significant positive effect on turnover intention. While working environment had significant positive effect on job satisfaction, and had a significant negative impact on turnover intention. Job satisfaction had a significant negative impact on turnover intention. In addition, it is also known that job satisfaction variables can mediate the indirect relationship between job stress and job satisfaction on turnover intention.

The purpose of this study was to find out the effect of financial rewards, promotions, and job satisfaction on employee performance mediated by employee loyalty, where an empirical study was conducted on employees of PT XXX. In this research, hypothesis testing is used and this type of research is included in quantitative research. Primary data in this study were obtained by distributing questionnaires as many as 224 valid questionnaires given to respondents who were employees of PT XXX. Sampling with proportional stratified random sampling technique. Data analysis was processed using Structural Equation Model (SEM) with Smart PLS software version 3.2. The results were found if financial rewards have a positive and significant effect on employee performance, promotion has a positive and significant effect on employee performance, and job satisfaction has a positive and significant effect on employee performance. Then financial rewards have a positive and significant effect on employee loyalty, but promotion does not have a positive and significant effect on employee loyalty, and job satisfaction has a positive and significant effect on employee loyalty. Then employee loyalty has a positive and significant effect on employee performance, financial rewards have a positive and significant impact on employee performance mediated by employee loyalty. However, job promotion does not have a positive and significant effect on employee performance mediated by employee loyalty, and job satisfaction has a positive and significant effect on employee performance mediated by employee loyalty. The limitation in this study lies in the use of samples, which were only obtained from one private hospital in North Jakarta. Therefore, the results in this study cannot be generalized to all hospitals, because of the different characteristics between hospitals.

Published: June 2022

Esta pesquisa teve como principal objetivo verificar as relações entre os estilos parentais predominantes, as dimensões da coparentalidade e os problemas de comportamento em crianças com transtorno do espectro autista (TEA). Caracterizou-se como de caráter exploratório, descritivo e correlacional, da qual participaram pais (n=45) e mães (n=45) de crianças diagnosticadas com TEA com média de idade de 59 meses. Os dados foram coletados no Centro Especializado em Reabilitação Física e Intelectual, no Sul do Brasil. Primeiramente, foi aplicado um questionário sociodemográfico e, posteriormente, aplicaram-se, com cada membro do casal, os seguintes instrumentos: Questionário de Dimensões dos Estilos Parentais, Escala da Relação Coparental e Questionário de Capacidades e Dificuldades. Por meio de análises estatísticas de correlação, constatou-se que os estilos parentais permissivo e autoritário foram associados a uma relação coparental negativa com pouco apoio do(a) companheiro(a), exposição a conflitos e boicote das funções parentais. Além disso, esse tipo relação coparental teve relação positiva com problemas de comportamento da criança com TEA. Esta pesquisa avança no conhecimento dos estudos no campo da parentalidade por evidenciar a relação bidirecional do comportamento da criança com TEA e os subsistemas parental e coparental. Contudo, os resultados não podem ser generalizados para todas as famílias de crianças com TEA, devido à limitação do número da amostra e aos instrumentos e análises empregados.
Somalia and the Islamist War: Assessing the Probability of Al-Shabab Winning or Losing the War with Somalia
Authors: Issa salwe Abdisalam
Published: June 2022

In this article, we assess the ongoing conflict between al-Shabaab on the one hand, and the Somali Transitional Federal Government (TFG) and the African Union Mission in Somalia(AMISOM), on the other. Though al-Shabab has been around since the mid 2000s, the current round of the conflict began in 2010 when AMISOM was deployed to Somalia to bolster the fledgling Somali government. The main thrust of the paper, therefore, is to reexamine what effect, if any, this African force has had on the conflict. Data were collected from 2009-2021 through monitoring and analysis was done using software. Data gathered included recording specific instances of violence between the two groups, including who orchestrated the violence, the location of the violence and the fatalities in each act of violence. While TFG/AMISOM made substantial gains initially against al-Shabab, the result did not specifically conclude which of the two groups is poised to win the war. However, it demonstrates that al-Shabab is able to stay in play by resorting to a host of other strategies which neither the TFG nor AMISOM can deploy.
Regenerative Medicine in Brazilian Television News: Storytelling and Public Engagement
Authors: ACERO LILIANA
Published: June 2022

Public access to media contributes to public understandings of science and medicine. This paper explores patterns in television coverage on Brazilian regenerative medicine, as they are presented in You Tube videos that reproduce some of the main  recent scientific and medical news in TV national or regional programmes regularly broadcast at peak times.  The study builds upon the coproduction approach to civic epistemologies in an emerging economy – i.e. the way the wider public makes sense of public policies and demands proof of their validity, as well as, verification of their implementation.  The coproduction approach is discussed in relation to two main of its analytical concepts:  the public understanding of science and public engagement in science. Using textual analysis, the article chooses selected narratives on scientific sense-making processes according to the representations of reporters, scientists, as well as, patients and their families. Among other, similarities are found between global and local reporting of scientific and medical news in the videos studied: news segments validate benefits while downplaying uncertainties and legal, ethical and social concerns. Sense-making in TV news coverage is based on what can be defined as reductionist imaginaries of science and medicine.  Also, news contents transmit a top-down communication model that influences the shaping of public understandings
Social Representation of Women in Buchi Emecheta’s The Joys of Motherhood and Flora Nwapa’s Efuru
Authors: GBAGUIDI Célestin
Published: June 2022

An analysis of the African fiction in the South of the Sahara shows a bias in the depiction of male and female characters. The purpose of this article is to explore the social representation of African women in post-colonial Africa as hardworking and intrepid characters, man’s companion, support and shield, and eventually as educators. Contrary to the distorted social perception society has of women in Africa, female novelists like Buchi Emecheta in The Joys of Motherhood and Flora Nwapa through Efuru, have deconstructed the social established norms giving masculine roles to their female characters. Nnu Ego, Adaku and Efuru – characters in these novels – have reversed the roles by working hard, protecting their families and by educating children and societies. Through the use of post-colonial criticism as backdrop, this paper deconstructs the negative representations that patriarchal societies have of women highlighting the predominant roles that female characters play. A qualitative data analysis and feminism approaches have been used to better explore the social representation of women in African patriarchal settings in this work.

Published: June 2022

Particle mixing is an important unit operation in many industry processes. This work employed the discrete element method (DEM) to characterize the mixing performance of iron ore particles in a horizontal high shear mixer. The simulation results were first compared with the positron emission particle tracking (PEPT) data reported by Forrest et al. to validate the DEM model. Then the effects of key operation factors such as impeller rotation speed, number of impellers and filling ratio on the mixing efficiency were discussed. The Lacey mixing index was employed to evaluate the mixing performance. The results show that the mixing efficiency of particles increased with increasing the number of impellers and their rotation speeds. On the other hand, the filling ratio was negatively related to the particles velocity and the mixing efficiency. This was because the effective space left for free movement of particles decreased as the filling ratio increased, and the mixing of particles was therefore restricted. In addition, the mixing rate of particles in the axial direction of the high shear mixer was much slower than that in the radial direction.

Published: June 2022

Meat fraud has been changed to an important challenge to both industry and governments because of the public health issue. The main purpose of this research was to inspect the possibility of using VIS/NIR spectroscopy, combined with chemometric techniques to detect the adulteration of chicken meat and fat in minced lamb meat. 180 samples of pure lamb, chicken and fat and adulterated samples at different levels: 5, 10, 15 and 20% (w/w) were prepared and analyzed after pre-processing techniques. In order to remove additive and multiplicative effects in spectral data, derivatives and scatter-correction preprocessing methods were applied. Principle Component Analysis (PCA) as unsupervised method was applied to compress data. Moreover, Support Vector Machine (SVM) and Soft Independent Modeling Class Analogies (SIMCA) as supervised methods was applied to estimate the discrimination power of these models for nine and three class datasets. The best classification results were 56.15 and 80.70% for classification of nine class and three class datasets respectively with SVM model. This study shows the applicability of VIS/NIR combined with chemometrics to detect the type of fraud in minced lamb meat.
Depictions of Diversity in Books Recommended for Storytime: A Cautionary Tale
Authors: Ingram Erin , Cahill Maria
Published: June 2022

Elements of equity, diversity, and inclusion (EDI) in diverse books support children’s intellectual, social, and emotional development. Public library storytime programs serve as venues to showcase books with characters of varied backgrounds, identities, and experiences who may or may not reflect those of the communities the libraries serve. Because storytime providers often rely on online resources to plan their programs, it is important to investigate the presence and quality of EDI elements in books recommended for storytimes by these resources. The present study analyzed the text, illustrations, and WorldCat metadata for a random sample of 481 children’s books recommended by six popular online resources for storytime planning. Results revealed an overall lack of EDI in the recommended books with few characters representing parallel cultures, living with a disability or chronic illness, practicing a religion other than Christianity, or communicating in a language other than English. The paper includes implications for storytime providers and library administrators in the areas of program planning, professional development, and program assessment.

Parkinson’s disease (PD), a progressive neurodegenerative disorder, affects dopaminergic neurons. Oxidative stress and gut damage play critical roles in PD pathogenesis. Inhibition of oxidative stress and gut damage can prevent neuronal death and delay PD progression. The objective of this study was to evaluate the therapeutic effect of embelin or the combination with levodopa (LD) in a rotenone-induced PD mouse model. At the end of experimentation, the mice were sacrificed and the midbrain was used to evaluate various biochemical parameters, such as nitric oxide, peroxynitrite, urea, and lipid peroxidation. In the substantia nigra (midbrain), tyrosine hydroxylase (TH) expression was examined by immunohistochemistry, and Nurr1 expression was evaluated by western blotting. Gut histopathology was evaluated on tissue sections stained with hematoxylin and eosin. In silico molecular docking studies of embelin and α-synuclein (α-syn) fibrils were also performed. Embelin alone or in combination with LD ameliorated oxidative stress and gut damage. TH and Nurr1 protein levels were also significantly restored. Docking studies confirmed the affinity of embelin toward α-syn. Taken together, embelin could be a promising drug for the treatment of PD, especially when combined with LD.
Drivers of Forest Pathogen Invasions

In the past 25 to 30 years, a marked increase has occurred in numbers of invasive alien pests and pathogens recorded, damaging agriculture, horticulture and forest environments. The reasons for this upsurge are clear: all involve human-driven factors, with, arguably, global trade as the most important component in the complex. Climate change is another major factor. Each plant transported through trade could carry cryptic pests or pathogens, which may be introduced into previously naïve environments and lead to major health issues on previously unaffected plants. Global trade in plants is a complex system, driven by a desire to use large plants in landscapes and demand for varied species for gardens. Examples of invasive alien pathogens causing wide-spread problems on a global scale currently include many Phytophthora species, Dothistroma needle blight of pines, and Xylella fastidiosa on a wide range of trees. A striking example recently was the spread of the Dutch elm disease pathogen, Ophiostoma novo-ulmi, in North America and Western Europe. Many invasive pathogens cause problems in localized regions, including Ceratocystis platani, killing Platanus in some European countries. Other examples include the threat of pine wilt nematode (Bursaphelenchus xylophilus), damage to Cupressus in Mediterranean landscapes caused by Seiridium cardinale, dieback of sweet chestnut (Castanea) caused by the canker pathogen Cryphonectria parasitica, and many others. In addition to global trade, climate change appears to be exacerbating the problems, with major influences on establishment and spread of alien invasive species. Hope lies in the enormous genetic ‘power’ of plants: humans could establish selection and breeding programmes that will ultimately enable us to plant trees with greater tolerance of changing climate and pests and pathogens, whether native or invasive.
Land governance for agroecology
Authors: Wittman Hannah , James Dana
Published: June 2022

Agroecological transitions aim to redesign the structure of contemporary global food systems to improve food security, ecosystem health, community development, worker livelihoods, and social and ecological justice. A fundamental principle of agroecology is the responsible governance of land. Yet land—as a concept, resource, and territory—is heavily contested through processes of colonization, enclosure, commodification, and financialization. The governance of land and natural resources is also intimately tied to questions of power and privilege—Who governs land? Who benefits, and who is excluded? These questions presuppose an ontological understanding of land that can also be contested: What is land, what purpose(s) does it serve, and for whom? In this article, we review key concepts at the intersection of land governance and agroecology. We take a case study approach to highlight how tensions around ontologies of land mediate agroecological futures in 2 settler-colonial contexts: Brazil and Canada. We then explore how land governance for agroecology might be experienced and understood across different land governance institutions—including relational and community commons, private property regimes, and new forms of hybrid land relations that challenge land privatization. We discuss how these land regimes influence people, landscapes, and agroecological outcomes and conclude with a consideration of the access, equity, and justice implications of different land governance approaches for sustainable food systems.
The Art of Making a Scene
Authors: Jack Max Z. , Conte Eugenia Siegel
Published: June 2022

Through an examination of four contrasting moments of public intervention, we investigate the sonic and cultural implications of “making a scene”—a style of social engagement that draws attention and exceeds expectations of the normative social functions of a particular space. The act of making a scene serves as an avenue for understanding the broad and simultaneous trends toward heightened stratification and political polarization that exhibit a desire to be heard. Be it in the form of impromptu street performances, protests, or riots—which range from exhilarating to terrifying—the desire to be heard can be conceived as a rejection of the liberal values of rational-critical discourse through the radical implementation of voice and sound as a means of temporarily appropriating space and redefining place. Reorienting social activity into a heightened emotive terrain, such acts short-circuit the quotidian, serving to incorporate strangers and force social engagement that would otherwise be unlikely to occur. Building upon and complicating notions of voice as expressive of identity and political agency, we posit that voice serves to transform emotional dynamics through an engagement with the physical qualities of space and its acoustic-vibrational possibilities. Capturing attention through expressive inflections of difference, making a scene momentarily flips the social logics of a place, revealing public space as a site of contestation characterized by the unequal flow and uneven habitability of different bodies and voices.
Moral Superiority as First Philosophy
Authors: Harman Graham
Published: June 2022

This article was prompted by Andrew J. Chung’s “Vibration, Difference, and Solidarity in the Anthropocene,” which was published in Resonance in 2021. Chung critiques the New Materialist movement for a dangerous proximity to the intellectual route that “anti-Blackness, colonial desire, and the universalization of Whiteness” have historically followed. After a brief introductory discussion of how certain aspects of Object-Oriented Ontology (OOO) might be of use to sound studies, and a lengthier definition of the “flat ontology” that seems to bother Chung, I mount a defense of the somewhat related New Materialist movement against his critique. There are three possible political critiques that one might make of flat ontology, and they are addressed one by one. First, there is Zoe Todd’s claim that the practice of ontology per se is already a form of colonialism. Second, someone might argue that in a moment of unusual political tension like the present, it would be immoral to change the subject and speak of the abstract sorts of intellectual problems usually associated with ontology. Third and finally, it is sometimes argued that modern transcendental or idealist ontologies are a force for political good, and that to flatten humans and nonhumans onto the same plane is to ratify existing hierarchies and hegemonies with no comparable gain in return. The conclusion is that none of these arguments works, and that while race remains a crucial moral and political theme, it cannot claim transcendental supremacy over the benefits of flat ontology.
R‐spondin signaling in the stomach: isthmal Lgr4 rules
Authors: Malagola Ermanno , Hayakawa Yoku , Wang Timothy C
Published: June 2022

R‐spondins are critical regulators of gastric epithelial cells, with Lgr5 receptor historically considered as their main signaling transducer. Recent work by Wizenty et al (2022) now revealed distinct roles for Lgr4 and Lgr5 in directing gland reconstitution following H. pylori infection, shedding new light on the complexities of Rspo signaling during gastric regeneration and raising questions about antral stem cell hierarchy.
