Authors: Lucibello Kristen M. , O’Loughlin Erin K. , Sabiston Catherine M. , Malouka Sabrina , O’Rourke Roxy H. , O’Loughlin Jennifer L.
Published: June 2023

Introduction

Although body weight has been positioned as a strong predictor of physical and mental health, positive and negative body-related psychosocial factors may also be important. Further, both theoretical tenets and empirical evidence suggest that these associations may differ by gender. Our objectives were to examine the associations between body-related self-conscious emotions (body shame, body authentic pride) and physical and mental health in young adults, and to identify potential differences in these associations by gender.

Methods

Data for this cross-sectional study were drawn from the Nicotine Dependence in Teens (NDIT) study for 799 young adults (M [SD] age = 33.6 y [0.5]; 43.9% male). We estimated the associations between each of body shame and body authentic pride (i.e. the exposures) and both self-rated physical and self-rated mental health (i.e. the outcomes) in linear regression models that controlled for age, education and body mass index, and we examined potential gender differences in these associations by conducting gender-stratified analyses.

Results

In females, self-rated health and mental health decreased by 0.37 and 0.38, respectively, with each unit increase in body shame. Self-rated health and mental health increased by 0.25 and 0.23, respectively, for each unit increase in body authentic pride. In males, self-rated health and mental health decreased by 0.35 and 0.45, respectively, with each unit increase in body shame, and increased by 0.32 and 0.21, respectively, with each unit increase in body authentic pride.

Conclusion

Interventions that focus on body weight to the exclusion of body-related self-conscious emotions may side-step a key contributor to self-rated health.

Introduction

S’il est vrai que le poids constitue un fort prédicteur de la santé physique et mentale, il n’en demeure pas moins que les facteurs psychosociaux positifs et négatifs en lien avec le corps sont également susceptibles de jouer un rôle important. En outre, tant des fondements théoriques que des données empiriques tendent à indiquer que ces associations peuvent varier en fonction du genre. Nos objectifs étaient, d’une part, d’analyser les associations entre les émotions liées à la conscience de son corps (honte corporelle, fierté corporelle authentique) et la santé physique et mentale chez les jeunes adultes et, d’autre part, de cerner les différences potentielles dans ces associations en fonction du genre.

Méthodologie

Les données utilisées dans cette étude transversale ont été tirées de l’étude sur la dépendance à la nicotine chez les adolescents (étude NICO) et portaient sur 799 jeunes adultes (âge moyen = 33,6 ans [écart-type = 0,5]; 43,9 % d’hommes). Nous avons estimé les associations entre, d’une part, la honte corporelle et la fierté corporelle authentique (variables d’exposition) et, d’autre part, l’état de santé physique autoévalué et l’état de santé mentale autoévalué (variables de résultat) dans des modèles de régression linéaire tenant compte de l’âge, du niveau de scolarité et de l’indice de masse corporelle, et nous avons étudié les différences potentielles dans ces associations en fonction du genre en effectuant des analyses stratifiées selon le genre.

Résultats

Chez les femmes, l’état de santé physique autoévalué et l’état de santé mentale autoévalué diminuaient respectivement de 0,37 et de 0,38 pour chaque augmentation d’une unité de la honte corporelle. L’état de santé physique autoévalué et l’état de santé mentale autoévalué augmentaient de respectivement 0,25 et de 0,23 pour chaque augmentation d’une unité de fierté corporelle authentique. Chez les hommes, l’état de santé physique autoévalué et l’état de santé mentale autoévalué diminuaient de respectivement 0,35 et de 0,45 pour chaque augmentation d’une unité de la honte corporelle. L’état de santé physique autoévalué et l’état de santé mentale autoévalué augmentaient de respectivement 0,32 et de 0,21 pour chaque augmentation d’une unité de la fierté corporelle authentique.

Conclusion

Les interventions qui ciblent le poids sans tenir compte des émotions liées à la conscience du corps sont susceptibles d’omettre un facteur clé de l’état de santé autoévalué.

Published: June 2023

L’identité de genre et l’attirance sexuelle sont des déterminants importants de la santé. Cette étude fait état de la répartition des identités de genre et de l’attirance sexuelle chez les jeunes Canadiens à l’aide des données de l’Enquête canadienne sur la santé des enfants et des jeunes de 2019. Parmi les jeunes de 12 à 17 ans, 0,2 % se sont identifiés comme non binaires et 0,2 % comme transgenres. Chez les jeunes de 15 à 17 ans, 21,0 % des répondants, dont un nombre plus élevé de personnes s’identifiant comme étant de genre féminin que de personnes de genre masculin, ont déclaré avoir une attirance non exclusive envers des personnes du genre opposé. Compte tenu des associations connues entre, d’une part, la santé et, d’autre part, le genre et l’attirance physique, il est recommandé de procéder à un suréchantillonnage des groupes sexuels minoritaires dans les études à venir pour obtenir des estimations fiables permettant de cerner les iniquités et pour orienter les politiques.

Cette étude qualitative met en lumière les points de vue de parents concernant les changements liés à la pandémie dans les programmes de promotion de la santé. Nous avons réalisé des entrevues téléphoniques semi‑structurées de 60 minutes avec 15 parents (des mères) d’enfants de la 4e à la 6e année entre décembre 2020 et février 2021 dans deux provinces de l’ouest du Canada. Les transcriptions ont été analysées au moyen d’une analyse thématique. Bien que certaines mères aient jugé que les documents de promotion de la santé avaient été utiles, la plupart étaient débordées et n’ont pas consulté les documents parce qu’elles les trouvaient intrusifs, avaient d’autres préoccupations ou devaient faire face à leurs propres sources de stress. Cette étude établit les principaux facteurs à aborder et à approfondir pour assurer l’efficacité des programmes de promotion de la santé lors des crises à venir.

Natural dyes have become more popular as a result of the harmful and carcinogenic effects of syntheticdyes. Anthocyanins are natural dyes that are widely used to replace synthetic dyes and can also act asantioxidants that can be found in rosella (Hibiscus sabdarrifa L.). This study aimed to obtain blushon cream from rosella flower extract (RFE) with olive oil and to determine the effect of olive oilconcentration on the evaluation results. The blush on cream was made in 3 formula, F1 (13,5%),F2 (15,5%), and F3 (17,5%). The cream was evaluated for 28 days in room temperature (15–30⁰C)which included organoleptic, pH, homogeneity, spreadability, adhesion, cream type, and viscosity.The results of the evaluation of RFE blush on cream with olive oil showed that F1, F2, and F3 metthe requirements for evaluating the preparation for organoleptic tests, pH, homogeneity, spreadability,adhesion, cream type, and viscosity. Variations concentration of olive oil gave no significant effect(p>0,05) on the organoleptic, pH, homogeneity, spreadability, and cream type and had significant effect(p<0,05) on the adhesion and viscosity test. The findings demonstrate that RFE can be made in blushon cream formulations with olive oil as emollients.

Published: June 2023

Este artículo presenta un análisis interpretativo del currículum de Geografía de la provincia de La Pampa. Para ello se realiza una indagación en los materiales curriculares jurisdiccionales, con el propósito de observar los aportes que los diseños efectúan a la enseñanza y el aprendizaje de los Objetivos de Desarrollo Sostenible (ODS). La Agenda 2030 y los ODS que plantea la Organización de las Naciones Unidas (ONU) en el 2015 proponen un reto a gobiernos, empresas, sociedad civil, actores sociales individuales y colectivos: el de trabajar para cumplir las metas propuestas. La educación no se encuentra ajena a estos desafíos, y a su vez, la Geografía, a través de la problematización de diversas temáticas, da cuenta del interés que presenta el abordaje en las aulas de educación secundaria y en la universidad los ODS en su interrelación con las realidades complejas a diferentes escalas de análisis. En este sentido, como docentes productores de materiales de cátedra e investigadores de nuestras propias prácticas, a partir de que somos mediadores del currículum, debemos interpretar dichos desafíos a la luz de incorporar nuevas miradas y perspectivas transversales. Por ello, una renovación de contenidos implicará tomar decisiones didácticas para su genuino tratamiento desde una educación comprometida con la formación de ciudadanos.
El paisaje sonoro en la conservación del patrimonio local. Un abordaje en General Daniel Cerri, provincia de Buenos Aires
Authors: Kraser María Belén
Published: June 2023

El paisaje se conforma a través del tiempo por las prácticas que la sociedad realiza sobre el espacio. Es, para algunos autores, la primera expresión de patrimonio cultural para una comunidad, puesto que resguarda componentes, valores y significados. El paisaje es a la vez expresión y apropiación de una comunidad, y puede ser representado mediante diversas manifestaciones, como los escritos para los que sirve de inspiración. Las letras de coplas son un medio para el estudio del paisaje que permite develar la historicidad que resguardan. El objetivo del escrito es fortalecer el abordaje del paisaje sonoro en el estudio de la espacialidad de General Daniel Cerri, en el partido de Bahía Blanca, sudoeste bonaerense. La metodología empleada corresponde al análisis de discurso y de las representaciones. El caso presentado permite contribuir al estudio del paisaje desde un enfoque que priorice, en la línea de estudio de carácter cualitativo, las sensaciones y valores que genera para la representación por parte de los propios actores locales. Asimismo, considerar el paisaje como el máximo exponente del patrimonio cultural abre la posibilidad de discusión para que este concepto se transforme en enfoque metodológico holístico y no sea simplemente una categoría conceptual más.

Authors: Rosati Germán
Published: June 2023

El trabajo presenta una alternativa metodológica para analizar trayectorias de uso de suelo. Toma como caso de estudio y prototipo un análisis de los cambios en el uso del suelo a un nivel general de Argentina (región pampeana, NEA, NOA y Cuyo). El objetivo es obtener un mapa con la mayor resolución posible que permita detectar las siguientes situaciones: 1) zonas recientes de expansión de frontera agraria; 2) zonas de agricultura “consolidada” y 3) zonas recientes de expansión de urbanización. Este trabajo se centra especialmente en el desarrollo de la metodología aplicada y en un primer intento de validación de la misma. A partir de datos de la Agencia Espacial Europea (ESA) vinculados a la “Climate Change Initiative-Land” (ESA-CCI-LC) del período 1992-2020 se genera una clusterización de trayectorias de uso del suelo mediante distancias de edición (utilizadas para el análisis de secuencias). Se obtuvieron 29 tipos de trayectorias a nivel píxel validadas por análisis visuales, con performance aceptable para la detección de diferentes trayectorias.

Diante da importância da participação da população do campo no mercado de trabalho, o presente estudo avalia o comportamento dos determinantes de tal inserção através de um modelo econométrico que estima as chances de um indivíduo encontrar-se economicamente ativo, modelo Probit. Este modelo é um tipo de análise de regressão apropriado para conjuntos de dados em que a variável dependente é de escolha binária. Os determinantes que apresentaram o maior impacto no sentido de elevar a participação foram: escolaridade, idade, posição no domicílio e raça. Visando realizar uma comparação entre os gêneros, estima também a participação para homens e mulheres separadamente. Dentre as diferenças encontradas, a principal foi que, embora o impacto da educação sobre a probabilidade estudada tenha sido o mais importante dentre os fatores analisados para ambos os gêneros, ele se mostrou mais marcante entre as mulheres para os maiores graus de instrução. Outro resultado importante foi quanto as variáveis chefes de família e se a pessoa é casada, sendo marcante para homens e mulheres, respectivamente.

Authors: Bharadwaj Alok , Gupta Mansi , Shakya Akanksha
Published: June 2023

Microorganisms are ubiquitous and have far-reaching effects on human life. Since their discovery in the 19th century, microorganisms have fascinated biologists. Microbes play a crucial role in the material and elemental cycles of the natural world. Growing own microbes for research purposes requires a significant time and financial investment. On the other hand, high-throughput sequencing technology cannot advance at the same clip as the culture method. The area of microbiology has made substantial use of machine learning (ML) methods to tackle this problem.

Classification and prediction have emerged as key avenues for advancing microbial community research in computational biology. This research compares the advantages and disadvantages of using different algorithmic approaches in four subfields of microbiology (pathogen and epidemiology; microbial ecology; drug development; microbiome and taxonomy).

Sensor Data Recovery of Faulty LOX/LH2 Rocket Engine Based on Multistage Graph Convolutional Network
Authors: Li Qiao , Li Xingchen , Zhang Wanxuan , Yao Wen
Published: June 2023

Engine, the indispensable core of a rocket, has a significant impact on space exploration, especially the high-thrust liquid-propellant rocket engine. Most new-generation manned rockets for space stations or lunar exploration prefer the [Formula: see text] engine for its high performance and environmental friendliness. However, the [Formula: see text] engine is susceptible to failure under extreme conditions, which could cause catastrophic consequences without timely warning. Real-time state detection and fault location can prevent some catastrophic outcomes, but they require reliable sensor data. Nevertheless, some sensor data could be lost due to signal interruptions or equipment shutdown caused by system faults. Therefore, recovering the lost data based on the remaining measurements is a critical challenge that involves dealing with the distribution gap between normal and faulty data. To tackle the data drift and achieve real-time and high-precision sensor data recovery of the faulty engine, a multistage model based on graph convolutional networks is proposed in this paper. Trained by a multiloss function, the model primarily recognizes the status of the engine and passes the status to the next stage. Then the second stage recovers the lost data by two graph convolutional networks specific to the normal or faulty state. Evaluated on the practical experimental data from Xi’an Aerospace Propulsion Institute, our method successfully identifies the state of the system with accuracy above 99.99% and recovers the incomplete sensor data with a mean absolute error under 0.0065. Moreover, some ablation studies demonstrate that the blocks of two-stage and graph convolution could achieve a 26% improvement over the vanilla neural network.
Experimental Investigations on High-Speed Aerodynamic Heating over Inflatable Decelerators
Authors: Prasanna Simha Padmanabha , Saravanan R. , Sajitha K. S. , Chandrasekar N. , Srinivasan K.
Published: June 2023

Heat transfer measurements and high-speed schlieren flow visualization were performed over a cylinder with an aft-attached inflatable decelerator configuration at Mach 3.9. Back wall temperature measurements using thermocouples were used to derive the heat flux distribution over the decelerator surface. A strong nonlinear rise in peak heat flux with angle of attack is observed and windward–leeward effects are quantified. Using appropriate flow and geometric symmetries, heat maps are generated over the regions of the decelerator, which are critical for its thermal design. The effect of fore-end bluntness in terms of peak heat fluxes and integrated heat loads is investigated. The results indicate a possibility of flying at a small angle of attack to reduce the integrated heat loads while simultaneously generating some lift. Tests up to an angle of attack of 20 deg show that even though the peak heating rises strongly, the overall integrated heat loads on the surface of the decelerator remain manageable. A local minimum is seen in peak heat flux levels on the surface at angles of attack of 12–16 deg.

Published: June 2023

To evaluate the feasibility of transjugular intrahepatic portosystemic shunt (TIPS) in children with portal hypertensive complications, PubMed and Cochrane Library were queried to identify clinical studies evaluating TIPS in patients <18 years old. Baseline clinical characteristics, laboratory values, and clinical outcomes were extracted. Eleven observational studies totaling 198 subjects were included in the study. The pooled technical success rate and hemodynamic success rate were 94% (95% confidence interval [CI]: 86–99%) and 91% (95% CI: 82–97%), respectively; ongoing variceal bleeding resolved in 99.5% (95% CI: 97–100%); refractory ascites was improved in 96% (95% CI: 69–100%); post-TIPS bleeding rate was 14% (95% CI: 1–33%); 88% of patients were alive or successfully received liver transplant (95% CI: 79–96%); and shunt dysfunction rate was 27% (95% CI: 17–38%). Hepatic encephalopathy occurred in 10.6% (21/198), though 85.7% (18/21) resolved with medical management only. In conclusion, based on moderate levels of evidence, TIPS is a safe and effective intervention that should be considered in pediatric patients with portal hypertensive complications. Future comparative studies are warranted.
Paroles d'experte - Enjeux de mémoire autour des expressions culturelles et artistiques : écrire l’histoire des artistes belgo-marocains
Authors: Zibouh Fatima
Published: June 2023

Les recherches liées à la contribution des minorités ethniques sur la scène artistique en Belgique ne sont pas encore légion. Ceci pose la question des enjeux de mémoire et d’archivage des expressions culturelles et artistiques des minorités, et des Belgo-Marocains en particulier. En effet, celles-ci nous permettent de comprendre les enjeux d’un contexte, car les artistes sont des caisses de résonnance des dynamiques sociales, culturelles et politiques en cours. Cet article présente un double objectif. D’une part, il a pour objet d’identifier les sources permettant de pallier cette méconnaissance de cette partie de l’histoire migratoire des Belgo-Marocains dans la littérature. D’autre part, l’idée est de partager les difficultés liées à l’archivage de ces expressions culturelles et artistiques ainsi que les alternatives méthodologiques mises en place pour retracer cette histoire, dans le contexte belge francophone en particulier.
Repatriation as disguised Expulsion in Interwar Belgium
Authors: Zian Yasmina
Published: June 2023

FR. Dans cet article, j’examine les corrélations entre crise économique, changements de pratiques d’éloignement des étrangers et création de catégories d’indésirables. Pour ce faire, je me penche sur les expériences individuelles des étrangers polonais pour voir comment le rapatriement des étrangers est devenu un moyen d’éloigner les étrangers pour des raisons politiques, alors qu’il était destiné à éloigner les étrangers qui se retrouvaient sans moyens de subsistance à la suite de la crise économique des années 1930. Cette étude se base sur les archives de la Police des étrangers : les dossiers généraux sur le rapatriement des chômeurs et les dossiers individuels des étrangers polonais expulsés. Cette recherche montre que la réponse du gouvernement belge à la crise économique a été, d’une part, une nouvelle utilisation du rapatriement et, d’autre part, la création d’une nouvelle catégorie d’indésirables. NL. In dit artikel bevraag ik de correlaties tussen de economische crisis, veranderingen in de verwijderingspraktijken van vreemdelingen en de creatie van categorieën van ongewenste personen. Daartoe bekijk ik de individuele ervaringen van immigranten om na te gaan hoe hun repatriëring een methode werd om vreemdelingen om politieke redenen te verwijderen, terwijl ze oorspronkelijk bedoeld was om vreemdelingen te verwijderen die als gevolg van de economische crisis van de jaren dertig geen middelen van bestaan meer hadden. Deze studie is gebaseerd op de archieven van de Vreemdelingenpolitie: de algemene dossiers over de repatriëring van werklozen en de individuele dossiers van uitgezette personen. Dit onderzoek toont aan dat het antwoord van de Belgische overheid op de economische crisis enerzijds een nieuw gebruik van repatriëring was en anderzijds de creatie van een nieuwe categorie “ongewenste personen”.
La campagne de régularisation des travailleurs clandestins en Belgique (1974-1976) : acteurs institutionnels et pratiques administratives
Authors: Khoojinian Mazyar
Published: June 2023

Le 1er août 1974, le gouvernement belge décréta l’arrêt de l’immigration de travail non qualifié en provenance des pays non-membres de la CEE. La décision fut accompagnée d’une campagne de régularisation des travailleurs clandestins étrangers. Si le mouvement social à l’origine de la mesure et la mobilisation syndicale qui en prit le relais sont bien connus, le rôle qu’y jouèrent les principaux acteurs institutionnels impliqués reste encore un terrain peu exploré. Cet article analyse les enjeux sociopolitiques de cette régularisation et souligne les actions respectives des acteurs, tant publics (Administration de l’Emploi, Police des Étrangers, Affaires étrangères) que privés (fédérations patronales, organisations syndicales, associations d’aide aux migrants), parties prenantes à l’opération.
Historiek van de Belgische asielinstellingen (1952-1988) in de wetgeving en beleidspraktijk. Een turbulente machtsstrijd tussen het ministerie van Justitie, Buitenlandse Zaken, en de UNHCR
Authors: Ecker Eva , Caestecker Frank
Published: June 2023

Entre 1952 et 1988, la compétence de déterminer le statut de réfugié a connu une évolution unique qui peut être attribuée à divers « bras de fer » entre principalement les Ministères de la Justice et des Affaires étrangères, et le HCR, qui se sont chaque fois traduits par des compromis typiquement belges. L’État belge a initialement confié cette responsabilité au HCR nouvellement créé, au moment un choix exceptionnel pour un pays de l’Europe de l’Ouest. Dans les années 1950, la reconnaissance de la qualité de réfugié comportait encore peu de risques pour le gouvernement. Cette situation a changé dans les années 1960, lorsque le profil du demandeur d’asile a évolué, la reconnaissance des réfugiés entrant davantage en conflit avec d’autres intérêts. Par conséquent, les ministères des Affaires étrangères et de la Justice ont voulu influencer la politique de reconnaissance de manière informelle dès la fin des années 60 afin de ne pas grever les prétendus intérêts belges. Dans les années 1970, la question a gagné en importance sur l’agenda politique, en partie parce que l’asile est devenu un canal d’immigration plus important. La loi sur les étrangers de 1980 a renforcé la position juridique des étrangers. Pourtant, le HCR ne pouvait pas garantir le droit d’appel. Cela a signifié la fin définitive du HCR en tant qu’acteur reconnaissant les réfugiés en 1988, la compétence de reconnaitre la qualité de réfugié ayant été transférée aux autorités belges.
Paroles d'expert - La transmission de l'histoire des migrations selon Gérard Noiriel
Authors: Landmeters Romain
Published: June 2023

Gérard Noiriel est directeur d'études émérite à l’École des hautes études en sciences sociales. Il fut d’abord un spécialiste de l’histoire ouvrière en France. En 1982, il a d’ailleurs défendu une thèse de doctorat consacrée aux ouvriers sidérurgistes et aux mineurs de fer du bassin de Longwy-Villerupt durant l’entre-deux-guerres. Durant la rédaction de cette thèse, et notamment au travers de ses dialogues radiophoniques avec Benaceur Azzaoui, il a pris conscience du vide historiographique concernant l’histoire des migrations en France. Cette préoccupation est déjà présente dans son premier article dans Le Mouvement social, la revue animée par sa directrice de thèse la professeure Madeleine Rebérioux. Défricher le champ historique des migrations en France deviendra programmatique à partir de son article dans les Annales de 1986. La publication de l’ouvrage Le Creuset français. Histoire de l’immigration en France (XIXe-XXe siècle) en 1988 le place parmi les pionniers de ce champ académique. Vingt ans plus tard, il reprend et approfondit ses propos dans Immigration, antisémitisme et racisme en France. Dans l’intervalle, d’autres ouvrages paraitront qui offriront des éclaircissements sur différents aspects de l’histoire des migrations : les réfugiés et sans-papiers, le rôle de l’État, les persécutions. Le 21 septembre 2021, Gérard Noiriel a été proclamé Docteur honoris causa de l'Université Saint-Louis - Bruxelles pour l’excellence de son parcours sur un plan scientifique, citoyen et humain.

Schistosomiasis is a disease affecting over 200 million people worldwide, but its treatment relies on a single agent, praziquantel. To investigate new avenues for schistosomiasis control, we have conducted the first systematic analysis of bromodomain-containing proteins (BCPs) in a causative species, Schistosoma mansoni. Having identified 29 putative bromodomains (BRDs) in 22 S. mansoni proteins, we selected SmBRD3, a tandem BRD-containing BCP that shows high similarity to the human bromodomain and extra terminal domain (BET) family, for further studies. Screening of 697 small molecules identified the human BET BRD inhibitor I-BET726 as a ligand for SmBRD3. An X-ray crystal structure of I-BET726 bound to the second BRD of SmBRD3 [SmBRD3(2)] enabled rationale design of a quinoline-based ligand (15) with an ITC Kd value of 364 ± 26.3 nM for SmBRD3(2). The ethyl ester pro-drug of compound 15 (compound 22) shows substantial effects on sexually immature larval schistosomula, sexually mature adult worms, and snail-infective miracidia in ex vivo assays. This compound will form the basis for future studies into new treatments for schistosomiasis.
Predicting the Reactivity of Acyclic Silylenes and Germylenes in Hydrogen Activation
Authors: Kleinhaus Michelle , Gessner Viktoria H.
Published: June 2023

Divalent group 14 element compounds (heavier carbenes) have been shown to serve as transition metal mimics and thus can activate small molecules and strong bonds at mild reaction conditions. Incorporating this special ability into novel transition metal-free catalysts requires careful tuning of the molecular properties. Finding the optimal combination of substituents is challenging and an experimentally highly deman¬ding process. In this work, we combine DFT and machine learning methods to predict the energy and activation barrier for the activation of dihydrogen by silylenes and germylenes, to thus facilitate the selection of candidates for small molecule activation in the future. We demonstrate that - based on the analysis of approx. 600 acyclic silylenes generated from 40 different substituents - the energy profiles can be reliably predicted by a simple model using the sum of energy increments of the substituents of the silylene. Furthermore, quantitative structure-activity relationships between the energies and the electronic and steric properties of the silylenes could be established, which enabled the prediction of the activation barrier with a mean average error of less than 9 kJ/mol. The model even enabled an extrapolation to silylenes with substituents not included in the original data set, and thus could predict new silylene structures for small molecule activation. Moreover, the reported procedure can also be applied to germylenes, and their energy profile quantitatively expressed as a function of the energies values of their silicon analogues. Overall, the presented protocol allows for a fast screening and prediction of possible candidates for H2 activation, which will accelerate the development of main group element catalysts in the future.

The primary plasticizers for the world’s most plasticized polymer, poly(vinyl chloride) (PVC), are organic phthalates, this despite being categorized as probable human carcinogens by the EPA. Di-2-ethylhexyl phthalate (DEHP or DOP) is such a typical PVC plasticizer. We sought to find an alternative plasticizer that lowered the glass transition temperature (Tg) and softened PVC, but was not as harmful to the environment and for our health as the currently employed phthalate plasticizers. We recently discovered that urea (U) could complex with amorphous polymers, such as atactic poly(methyl methacrylate) (PMMA) and poly(vinyl acetate) (PVAc). Compared to neat samples, the Tgs of the PMMA-U and PVAc-U complexes were increased and decreased, respectively. However, when complexed with dimethylurea (DMU), the Tg of the PMMA-DMU complex was lowered. Since Tgs of PMMA and PVAc were lowered by either U or one of its derivatives, this prompted us to investigate whether they could interact and complex with another largely amorphous polymer PVC, that is often plasticized, to soften and lower its Tg. Shifts in the vibrational frequencies observed by Fourier-Transform Infrared spectroscopy and Differential Scanning Calorimetry thermograms indicated that U, its derivative tetramethylurea (TMU)], and the related compound Acetamide (AC) were complexing with PVC. All three complexes (PVC-U, -TMU, and –AC) showed significantly lowered Tgs. Preliminary mechanical property measurements of PVC-U and PVC-AC films showed they were softer and more pliable than PVC films. Consequently, we believe our preliminary results warrant further examination of U, AC, and TMU as potential effective and less harmful PVC plasticizers.

El impacto de la tasa de interés referencial sobre las tasas de interés por tipo de crédito en los bancos sistémicos del Perú
Authors: Mitma Jhonnathan
Published: June 2023

Varias investigaciones acerca del efecto traspaso de la tasa de interés referencial sobre las tasas de interés presentan únicamente resultados para indicadores agregados, es decir, no miden el impacto de la tasa referencial para cada tipo de tasa de interés. El objetivo de este artículo es determinar el impacto de la tasa referencial sobre las tasas de interés activas por tipo de crédito utilizando data mensual de los cuatro bancos más grandes del Perú de enero del 2011 a diciembre del 2018. Se encuentra que la tasa de interés de referencia tiene un impacto causal sobre las tasas de interés hipotecaria, corporativa y de grandes empresas, pero no sobre las tasas de interés para consumo y para medianas, pequeñas y microempresas.
