Visible-light-induced radical cascade cyclization: a catalyst-free synthetic approach to trifluoromethylated heterocycles
Authors: Yang Chuan , Shi Wei , Tian Jian , Guo Lin , Zhao Yating , Xia Wujiong
Published: January 2024

A visible-light-promoted research protocol for constructing dihydropyrido[1,2-a]indolone skeletons is herein described proceeding through a cascade cyclization mediated by trifluoromethyl radicals. This method allows the efficient synthesis of various indole derivatives without the need of photocatalysts or transition-metal catalysts. Mechanism experiments indicate that the process involves a radical chain process initiated by the homolysis of Umemoto's reagent. This straightforward method enables a rapid access to heterocycles containing a trifluoromethyl group.

Authors: Zhu Qinsong , Zhang Chen , Yu Fuhang , Xu Yan
Published: January 2024

For enhance the aerodynamic performance of aero engine blades, the parameters and drag-reduction mechanism of micro-texture to reduce blade surface flow loss are investigated in this study. First, a simplification simulation method is proposed to reduce the calculation cost and determine the aerodynamic parameters of the blade model through the comparison of flow field characteristics and parameters of the blade simulation result. Secondly, the placement position and geometrical parameters of micro-texture with lower energy loss are determined by CFD (Computational Fluid Dynamics) simulation for the established micro-texture on the blade surface and the drag reduction mechanism is analyzed based on the simulation result. The triangular rib with a depth of 0.2mm and width of 0.3mm has the best drag reduction performance, and this micro-texture has an energy loss coefficient reduction of 1.45% and a drag reduction of 1.31% on a single blade. Finally, the blades with the optimal micro-texture parameters are tested in the intermittent wind tunnel. The experimental results show that the micro-texture decreases the energy loss by 3.7% of a single blade under the working conditions of 57° attack angle and 136.24m/s, which is pleasing for the drag reduction performance of the integral impeller with 45 blades.
On the meaning of intonational contours: a view from scalar inference
Authors: Göbel Alexander , Ronai Eszter
Published: January 2024

This paper investigates the meaning of intonational contours by experimentally testing how they affect the likelihood of scalar inference (SI) calculation. Our main test case is the rise-fall-rise contour (RFR) which, based on prior theoretical work, is predicted to either increase or decrease the likelihood of SI. We conducted two experiments using an inference task: one where participants first produce a target sentence with their choice of contour and one where participants listen to a pre-recorded target sentence with a particular contour. The experiments converged in showing that the RFR increases SI rate relative to a neutral fall. Additionally, production data revealed the frequent use of another contour that resembles the Contradiction Contour, which we label Concession Contour. This contour also led to an increase in SI rate, although to a lesser extent than the RFR. In addition to informing the theoretical literature on RFR, our results also highlight the methodological importance of controlling for intonation in the study of SI.
Everyone except possibly Ann
Authors: Mayr Clemens , Vostrikova Ekaterina
Published: January 2024

This paper deals with the interaction of modals and exceptives as in Every student passed, except possibly Ann. Arguments are put forward motivating a parse for at least some such sentences combining features of the two standard analyses for exceptive constructions, namely the phrasal and clausal analyses. A novel approach based on the well-known idea of exception as set subtraction coupled with exhaustification contributed by an operator EXH is proposed. Crucially, on this approach the prejacent S of EXH is conjoined with [ modal EXH S ]. That is, the modal is only present in the second conjunct where it takes scope over the clause EXH S, which is partially elided. This leads us to consider further data suggesting that the EXH used in such constructions does not assert the prejacent but rather only excludes alternatives. That is, it is the first conjunct alone that contributes assertion of the prejacent.

Published: January 2024

Repeated emergence and disappearance of the Bering Land Bridge during the Quaternary triggered multiple faunal exchanges between northeast Asia and North America. Older (Early to Middle Pleistocene) dispersal events through the bridge followed by its submergence often lead to the vicariant origin of sister species, whose allopatric ranges are currently separated by the Bering Strait. Among bumblebees, examples of these pairs include Bombus balteatus Dahlbom 1832 – B. kirbiellus Curtis 1835, B. pyrrhopygus Friese 1902 – B. polaris Curtis 1835, and B. hyperboreus Schönherr 1809 – B. natvigi Richards 1931. However, integrative taxonomic analyses of new bumblebee samples from hard-to-reach areas of the Chukotka Peninsula (Russian Far East) reveal that the Nearctic B. kirbiellus is present at the north-eastern margin of Asia and that its Asian specimens share the COI haplotype with populations from Alaska. Although B. kirbiellus originated as a Nearctic relative of B. balteatus and was thought to be an endemic to North America, there was a Late Pleistocene (or more recent) expansion of this species from Alaska to Chukotka. Our findings indicate the possibility of secondary expansion of vicariant species through the Beringia during the Last Glacial Maximum or via a more recent migration event across the Bering Strait.

Authors: Jesus Ronald Souza de
Published: January 2024

Ao longo de mais de 70 anos, é notável no cinema brasileiro a frequência de abordagens sobre o Sertão em suas obras. Desde O cangaceiro (Lima Barreto, 1953) e O canto do mar (Alberto Cavalcanti, 1952), centenas de filmes de longa-metragem de ficção já fizeram uso dessa abordagem. Um montante tão vasto de objetos voltados para espaços similares – o semiárido e a caatinga nordestina, com suas culturas, pessoas e peculiaridades – acabou por estabelecer um conjunto de elementos muito próprios de narrativas voltadas especificamente a essas geografias. O presente texto visa listar esses filmes e apresentar os principais elementos de linguagem que nos permite observar a formação e consolidação de um gênero cinematográfico específico. Para isso, serão apresentados relatos de cineastas, resultados de análises fílmicas, assim como crítica de processo a respeito da elaboração dessas obras. Coletados ao longo de mais de 10 anos de pesquisa, esses elementos permitem demonstrar a existência de um cinema essencialmente próprio da cultura brasileira.

Authors: Pabón Jenny , Osorio Valentina , Gallego Claudia Patricia
Published: January 2024

En el procesamiento del fruto de café, en la etapa de secado se disminuye el contenido de agua y de esta manera se afecta el crecimiento de hongos toxigénicos. Para evaluar la inocuidad del café cuando se realizan interrupciones durante el secado mecánico, se aplicó un diseño factorial 2x4+1, con dos tiempos de secado inicial (6 y 12 horas), con cuatro tiempos de interrupción (12, 24, 36 y 48 horas) y un testigo con secado mecánico sin interrupción. Se cuantificaron las unidades formadoras de colonias (UFC) de hongos y levaduras, contenido de humedad y actividad del agua del café húmedo antes y después de la interrupción y al finalizar el secado. Se determinó la concentración de ocratoxina A y los compuestos químicos con la técnica NIRS en los granos de café de cada tratamiento. Según el ANAVA, el contenido de humedad del café con tiempo de secado inicial de 12 horas fue menor significativamente al secado de 6 horas con valores de 42,29% y 47,49%, respectivamente. El contenido de hongos y levaduras fue mayor en el café húmedo sometido a interrupción (4,14x106 UFC/g) que en el café pergamino seco (8,19x103 UFC/g). Los valores de ocratoxina A no presentaron efecto de tratamientos.

Authors: Karicha Jona Mbaabu , Ifedha Stephen Akaranga , Musili Telesia Kathini
Published: January 2024

The success and development of each nation are based on the tenets which are cherished by its populace. This is partly expressed in the way they subscribe to their religious and socio-cultural values, which in turn promote social economic development. This article examined the role of the Roman Catholic Church in fostering the well-being of people in Meru County in Kenya. The research was guided by the following question: What role has the Roman Catholic Church played in the social economic development of the people in Meru County? Two theories, namely the Hybrid Quasi Theory and the Complementary Theory were employed to contextualize the research findings. The purposive sampling technique was utilized to select thirty participants who participated in the study. Questionnaires containing both open and closed-ended items were administered to the clergy from the thirty sampled parishes of the Roman Catholic Church in Meru County. The findings revealed that the church has partnered with the national and county governments to transform the Ameru people’s lives. This study highlighted the need for both the government and non-governmental development agencies to frequently consult with the church in advancing development. This study will benefit the people of Meru, the Roman Catholic Church and other churches, academicians and in particular scholars of religion and persons in social and economic positions of decisive influence. The study further creates an awareness to the ordinary populace of Meru County that the church not only enhances their spiritual well-being but also acts as an agent of social, economic and political development.

Published: January 2024

The study aims to analyze the synergies between internal factors (i.e., emotional intelligence and resilience) and external factors (i.e., governmental support) on the performance of tourism organizations in the post-disaster recovery phase. Data collected from the sample of 390 managers and owners in the tourism industry were analyzed using structural equation modeling with partial least squares (PLS-SEM) as an appropriate model method with variables containing multiple items and multiple causal relationships. Our findings reveal that the resilience of tourism organizations (during and post-pandemic crisis) is positively influenced by the employees’ and managers’ emotional intelligence and government support. Planned and adaptive resilience significantly affects organizational response to disruptive events and organizational performance. Our findings guide tourism organization managers and government authorities and help them make timely decisions based on the relationship between resilience, emotional intelligence, and governmental support during and after a crisis. Managers need to be aware of the importance of emotional intelligence in managing the business in uncertain/turbulent times and to be concerned with improving emotional intelligence for themselves and their employees. Our study is one of the first to analyze the pandemic’s effects in the post-disaster recovery phase and the first one focused on Romania’s tourism organizations.

Light pollution is recognized as a global issue that, like other forms of anthropogenic pollution, has a significant impact on ecosystems and adverse effects on living organisms. Plentiful evidence suggests that it has been increasing at an unprecedented rate at all spatial scales. Chile—which, thanks to its unique environmental conditions, has become one of the most prominent astronomical hubs of the world—seems to be no exception. In this paper we present the results of the first observing campaign aimed at quantifying the effects of artificial lights at night on the brightness and colors of the Chilean sky. Through the analysis of photometrically calibrated all-sky images captured at four representative sites with an increasing degree of anthropization, and the comparison with state-of-the-art numerical models, we show that significant levels of light pollution have already altered the appearance of the natural sky even in remote areas. Our observations reveal that the light pollution level recorded in a small town of the Coquimbo Region is comparable with that of Flagstaff, Arizona, a ten times larger Dark Sky city, and that a mid-size urban area that is a gateway to the Atacama Desert displays photometric indicators of night sky quality that are typical of the most densely populated regions of Europe. Our results suggest that there is still much to be done in Chile to keep light pollution under control and thus preserve the darkness of its night sky—a natural and cultural heritage that it is our responsibility to protect.
Formation of Massive Black Holes with M = (103–108) M
⊙ at Pre-quasar Epochs through Hoyle–Lyttleton–Bondi Accretion of Self-interacting Dark Matter onto a Moving Seed

The presence of supermassive black holes with M ∼ 109
M
⊙ hosted by the luminous quasars at cosmological redshift z ≥ 6 is still an open problem in astrophysical cosmology. Here we study the formation of massive black holes at high redshift (z ≫ 7) through Hoyle–Lyttleton–Bondi accretion of self-interacting dark matter (SIDM) onto a 20 M
⊙ seed black hole moving with a velocity ∼100 km s−1 inside the short, mean-free path region of an SIDM halo. We consider observational constraints on a specific SIDM cross section, σ/m
dm = (0.1–5) cm2 g−1. Formation timescale of massive black holes with M = (103–108) M
⊙ is calculated for the universal Navarro–Frenk–White (NFW) profile, singular isothermal sphere (SIS), other power-law profiles with a cusp index 2.19 ≤ γ ≤ 2.5 of accreted dark matter, and modified-core isothermal profiles. The ambient sound speed is taken as C

200 = (1012–1014) M
⊙ favors formation of massive black holes with M = (103–108) M
⊙ at high redshift, well before quasar epoch. In this profile, these black holes grow within timescales (0.1–69) Myr at z = 16–20. For the SIS profile, the black hole formation timescales are short compared to NFW. For power-law profiles, massive black holes with M = (106–108) M
⊙ grow within a few tens to 100 Myr (z = 5–30). For modified-core isothermal profiles, the timescale of massive black hole formation is in the range (0.79–464.08) Myr (z = 8–30).

The Parker Solar Probe (PSP) provides us with an unprecedentedly close approach to the observation of the Sun and hence the possibility of directly understanding the elementary process that occurs on the kinetic scale of particles' collective interaction in solar coronal plasmas. We report a type of weak solar radio burst (SRB) that was detected by PSP when it passed a low-density magnetic channel during its second encounter phase. These weak SRBs have a low starting frequency of ∼20 MHz and a narrow frequency range from a few tens of MHz to a few hundred kHz. Their dynamic spectra display a strongly evolving feature of the intermediate relative drift rate decreasing rapidly from above 0.01 s−1 to below 0.01 s−1. Analyses based on common empirical models of solar coronal plasmas indicate that these weak SRBs originate from a heliocentric distance of ∼1.1–6.1 R
S (the solar radius), a typical solar wind acceleration region with a low-β plasma, and that their sources have a typical motion velocity of ∼v
A (Alfvén velocity) obviously lower than that of the fast electrons required to effectively excite SRBs. We propose that solitary kinetic Alfvén waves with kinetic scales could be responsible for the generation of these small-scale weak SRBs, called solitary wave radiation.
The Effect of Salinity on Ocean Circulation and Ice–Ocean Interaction on Enceladus
Authors: Zeng Yaoxuan , Jansen Malte F.
Published: January 2024

Observational data suggest that the ice shell on Enceladus is thicker at the equator than at the pole, indicating an equator-to-pole ice flow. If the ice shell is in an equilibrium state, the mass transport of the ice flow must be balanced by the freezing and melting of the ice shell, which in turn is modulated by the ocean heat transport. Here we use a numerical ocean model to study the ice–ocean interaction and ocean circulation on Enceladus with different salinities. We find that salinity fundamentally determines the ocean stratification. A stratified layer forms in the low-salinity ocean, affecting the ocean circulation and heat transport. However, in the absence of tidal heating in the ice shell, the ocean heat transport is found to always be toward lower latitudes, resulting in freezing at the poles, which cannot maintain the ice shell geometry against the equator-to-pole ice flow. The simulation results suggest that either the ice shell on Enceladus is not in an equilibrium state or tidal dissipation in the ice shell is important in maintaining the ice shell geometry. The simulations also suggest that a positive feedback between cross-equatorial ocean heat transport and ice melting results in spontaneous symmetry breaking between the two hemispheres. This feedback may play a role in the observed interhemispheric asymmetry in the ice shell.

Published: January 2024

Introduction: Bone marrow examination (BME) is a useful tool in the diagnosis of haematological and non-haematological diseases. It plays an important role in early diagnosis of the underlying cause of pyrexia of unknown origin (PUO) and can influence the management of patients. Bone marrow aspiration (BMA) plays a very important role in establishing a definitive diagnosis in cases of PUO. The aim of this study was to review the indications and usefulness of bone marrow aspirates sent for microbiological evaluation as a diagnostic tool with histopathological correlation.
Methodology: A prospective study was conducted from 1 January 2017 to 30 September 2019 in the Department of Microbiology and Pathology on the bone marrow aspirates of patients of all groups.
Results: A total of 148 bone marrow aspirates were included. The cases were categorized as classical PUO (n = 81/148, 54.7%), nosocomial PUO (n = 4 /148, 2.7%), neutropenic PUO (n = 18/148, 12.1%), and immunocompromised PUO (n = 45/148, 30.4%), among which were systemic lupus erythematosus cases n = 8/45 (22.2%), human immunodeficiency virus positive cases n = 10/45 (17.7%), and renal transplant cases n = 27/45 (60%). A total of 28 BMAs were positive for microorganisms, out of which bacterial pathogens were n = 12 (42.8%), mycobacterial n = 12, 42.8%, fungal (n = 3, 10.7 %), and viruses (n = 1, 3.5%).
Conclusions: This study helped in highlighting the role of bone marrow examination as an important diagnostic method in the diagnosis of infectious diseases.

Published: January 2024

Introduction: Bovine babesiosis caused by the protozoan Babesia bovis is a worldwide disease and causes great economic damage to livestock. There are no studies on the epidemiology of this disease in native breeds such as Crioula Lageana cattle raised in the South of Brazil.
Methodology: DNA samples from 311 animals were amplified by polymerase chain reaction (PCR) for the identification of the gene rap-1 (Rhoptry Associated Protein 1) from B. bovis. An epidemiological questionnaire was used to determine the risk factors associated with infection.
Results: The prevalence of B. bovis infection was 72% (224/311). Age and tick infestation affected infection. The factors associated with infection were the breeding objective (p = 0.042; CI = 0.746-0.995; OR = 0.861), contact of cattle with other animal species (p = 0.002; CI = 0.517-0.860; OR = 0.484), absence of tick control (p = < 0.001; CI = 0.074-0.480; OR = 0.188) and timing of tick treatment (p = 0.026; CI = 0.673-0.975; OR = 0.810), and these were considered to be factors that can protect against the disease.
Conclusions: The Crioula Lageana cattle breed has near enzootic stability with regards to B. bovis infection.
The Idioptera-Eloeophila complex (Diptera: Limoniidae): a phylogenetic solution to an old taxonomic misunder­stand­ing
Authors: Santos Daubian , Ribeiro Guilherme Cunha
Published: January 2024

Abstract

Eloeophila Rondani, 1856 and Idioptera Macquart, 1834 are two genera of the family Limoniidae (Diptera) distinguished by the presence of a supernumerary cross-vein m-cu. Although these genera were previously combined, there has been a lack of phylogenetic tests to investigate the evolutionary relationship between them. In this study, we conducted a cladistic analysis that indicates that Idioptera form a clade within Eloeophila, and therefore the two genera should be synonymized under Idioptera. Consequently, 87 species of Eloeophila are transferred to Idioptera.
Spiders (Arachnida, Araneae) of the Visimskiy Biosphere Reserve (Middle Urals): 37 years of arachnological research
Authors: Ukhova Nadezhda , Esyunin Sergei , Sozontov Artëm
Published: January 2024

More than 30 articles concerning spiders’ diversity and assemblages’ structure within the Visimskiy Reserve have been published since its establishment 52 years ago. The literature provides data on 260 recorded species, one of which has been described as a new species. The majority of these records were not annotated. The peak of publication activity was in the 2nd part of the 1990s and the beginning of the 21st century. The greatest amount of material was collected between 2012 and 2018, within long-term plots with quantitative observations of epigean and litter-dwelling spiders, focusing on wind-throw and post-fire successions.

This article summarises all the literature and field primary data. We also list 18 species new to the reserve's fauna, which currently comprises 278 species. Doubtful and invalid records have been excluded from the species list. The occurrences in the dataset are supported by detailed information about vegetation cover at the time of collection. This is important in the context of research on fauna and community changes along the vegetation succession, including wind-thrown and post-fire restoration.
Modicella guangxiensis (Mortierellomycota, Mortierellaceae), a new species from south-western karst areas of China
Authors: Mou Guang-Fu , Bau Tolgor
Published: January 2024

Modicella Kanouse (1936) is the only genus of Mortierellaceae known to produce macroscopic fruiting bodies in the form of small, whitish, round sporocarps. Specimens which belong to Modicella were collected during our field investigations in tropical karst areas of China. Based on morphological characteristics and phylogenetic analysis, a new species is introduced.

Modicella guangxiensis is described as a new species from tropical karst areas of China. The main distinguishing characteristics of M. guangxiensis are the number of sporangiospores per sporangium (11–18), the size of sporangiospores (14–34 × 12–27.5 μm) and the surface of some hyphae with hemispherical tuber. The phylogenetic analyses, based on the internal transcribed spacer (ITS) and the large subunit (LSU) regions of rDNA sequences using Bayesian (BA) and Maximum Likelihood (ML) methods showed that the new taxon is closely related to M. reniformis.

Authors: Dorr Laurence J. , Wurdack Kenneth J.
Published: January 2024

Morphological and molecular phylogenetic evidence indicate that Eleutherostylis Burret (Malvaceae, Grewioideae), a monotypic genus described from New Guinea, is best considered a synonym of Grewia L., a species-rich genus widespread across the Paleotropics and found in Africa, Arabia, Asia, Australia and the western Pacific. A new combination, based on E. renistipulata Burret, G. renistipulata (Burret) Dorr, comb. nov., is proposed. Original material of the basionym could not be located and a neotype is designated. A lectotype is designated for G. morotaiensis Kosterm., a synonym of G. renistipulata.

À partir d’une recherche-intervention déployée au cœur des cellules de crise d’une multinationale faisant face à la crise Covid-19, nous abordons un point peu abordé dans la littérature, celui de l'antinomie spécifique rencontrée par les multinationales. Ces dernières doivent en effet déployer une réponse cohérente tout en naviguant à travers les contextes variés de leurs entités locales. L’étude de la littérature nous permet de nous aligner avec les travaux ayant synthétisés les retours d’expérience des crises sanitaires, à ceci près qu’ils ne tiennent souvent pas compte des complexités rencontrées par les multinationales face à des réglementations, contextes et environnements variés. Dans le cadre d’un questionnaire partagé avec 19 cellules de crise activées d’une même multinationale, nous montrons que l'organisation homothétique de la crise favorise la flexibilité grâce à une influence ascendante des cellules de crise locales. En illustrant les bénéfices de la subsidiarité dans l’organisation des différentes cellules de crise, les résultats permettent de proposer aux multinationales de développer une organisation de gestion de crise adaptée pour faire face aux crises complexes et multicouches à venir.
Les couvertures du second Moyen Âge en Alsace : un état des connaissances
Authors: Werlé Maxime , Kill René , Schwien Jean-Jacques
Published: January 2024

L’Alsace médiévale a principalement connu trois types de matériaux de couverture, employés sous des formes diverses et de façon concomitante : le chaume, le bois et la terre cuite. La présente contribution vise à dresser un état des connaissances sur l’emploi de chacun de ces matériaux. La période considérée, du xiie au xvie siècle, est marquée par quelques évolutions majeures, nullement linéaires au plan chronologique et géographique : 1° la réapparition aux xiie-xiiie siècles des couvertures en terre cuite dans un paysage jusqu’alors largement dominé, pour ce que l’on peut en percevoir, par les couvertures en chaume et en bois ; 2° le développement de la production de tuiles creuses à crochet, qui s’impose durablement dans les villes dès les xive-xve siècles, au détriment des autres matériaux de couverture ; 3° a contrario, le maintien en contexte rural, villageois et castral, des couvertures en chaume et en bois bien au-delà du Moyen Âge ; 4° l’apparition et le développement sans précédent, dans la première moitié du xvie siècle, de couvertures en tuiles plates en écaille (au détriment cette fois des anciennes tuiles creuses dont la production devient marginale). La démonstration, notamment fondée sur des données issues de fouilles et d’études archéologiques du bâti, mais aussi sur l’exploitation des sources écrites et iconographiques, cherchera à préciser les étapes chronologiques de ces évolutions et à déterminer les raisons de ces changements.
Piccoli proprietari terrieri italiani a São Paulo, 1911. Un saggio di storia visiva
Authors: Vangelista Chiara
Published: January 2024

L’article se concentre sur un album photographique publié lors de l’Exposition internationale de 1911 à Turin. L’analyse visuelle et textuelle révèle le contexte de production des photographies. Cela comprend à la fois le contexte général, marqué par des crises de surproduction le morcellement des grandes propriétés, et des aspects spécifiques liés à la production de l’album. Ainsi le projet éditorial, les caractéristiques du reportage photographique, et les conditions matérielles de réalisation sont examinés. De plus, l’étude explore les interactions avec les sujets représentés, les relations de pouvoir, les relations de genre, l’adaptation des migrants à la culture matérielle et aux relations sociales paulistes. Enfin, elle met en lumière les innovations introduites et les traces laissées par les occupants précédents.
Leni Riefenstahl y el poder de las imágenes: apuntes sobre El Triunfo de la Voluntad (Triumph des Willens, 1935) y el prólogo de Olympia (1938).
Authors: Peñalosa Xavier Puig
Published: January 2024

Si toda imagen implica una previa y determinada elección constructiva para así poder transmitir un particular significado, en el caso de la cinematografía es la sucesión ‒anterior y posterior‒ de aquellas (fotogramas) y limitadas mediante el montaje (secuencia), donde adquieren su significación. En el caso las dos películas que a continuación se comentarán, a saber, El Triunfo de la Voluntad (Triumph des Willens, 1935) como –especialmente‒ en el prólogo de Olympia (1938), ambas de la cineasta Leni Riefenstahl, cabe añadir que, unido a lo anteriormente expuesto, el contenido formal que muestran esas imágenes, en realidad apelan simbólicamente a factores extradiegéticos que son los que, semánticamente, otorgan la real significación de aquellas. Por ello, serán las cuestiones conceptuales expuestas, las que constituirán la guía metodológica en el análisis de las dos películas citadas.

Este artículo analiza la experiencia editorial de la Editorial Quimantú (1971-1973) creada por Salvador Allende durante el período de la Unidad Popular en Chile. En él se aborda a partir de distintos ejes los alcances y proyecciones de esta experiencia histórica buscando en ellos distintas formas de articulación entre arte y política en el marco de la implementación de la vía chilena al socialismo. Se utilizan para ello las perspectivas teóricas de la sociología del arte retomando discusiones como la democratización cultural, el libro y la lectura y la disputa por la hegemonía cultural. El artículo como base una investigación de archivos y entrevistas a una diversidad de actores que hicieron vivir una experiencia a partir en que confluyeron en distintas escalas arte, resistencia y creación social en la construcción cultural de un proyecto político.
« Flesh for Fantasy » ? Expressions musico-visuelles de la masculinité dans les clips de hard rock et de heavy metal des années 1980
Authors: Gaudin Antoine
Published: January 2024

En tant que défilé permanent de corps engagés dans des performances spectaculaires qui sont aussi d’intensives performances de genre, le secteur du clip constitue une scène privilégiée pour la construction et la négociation des identités culturelles associées aux genres. Centré sur la question des masculinités, cet article prend pour objet le vaste corpus des vidéos de hard rock et de heavy metal multi-diffusés dans la première décennie de MTV. Quelles expériences musico-visuelles ces clips proposaient-ils à leurs audio-visionneur·ses ? Quels rapports entre hommes et femmes mettaient-ils en scène ? En quoi contribuent-ils à éclairer certaines façons de se définir en tant qu’homme dans le contexte social, politique et médiatique des années 1980 ? Derrière la reconduction de certains stéréotypes sexuels (et le détournement de certains autres), que nous communiquent ces objets audiovisuels sur la construction d’un sujet masculin peut-être plus ambigu qu’il n’y paraît ?
UMA QUESTÃO INDÍGENA:
Authors: Zuzart Carmelita
Published: January 2024

Entre os anos de 1630 e 1654, a Companhia holandesa das Índias Ocidentais (WIC) ocupou as Capitanias do Norte do Brasil. Seu interesse estava relacionado principalmente à possibilidade de auferir lucros com açúcar, em represália aos vários embargos impostos pela Monarquia de Habsburgo. Apesar dos reveses da invasão, a produção açucareira não só permaneceu, como financiou a guerra da resistência luso-brasileira. Paralelamente, também foi mantida a produção da farinha de mandioca, indispensável para o sustento dos colonos e das tropas na guerra. Grande parte do plantio de mandioca, como de outros viveres, era feito pelos indígenas, cujos roçados ficavam nas aldeias que normalmente circunvizinhavam os engenhos. Dessa maneira, torna-se imprescindível para o estudo do que foi a ocupação holandesa no Brasil entender o papel dos povos nativos nessa guerra. Para além de fornecerem braços que engrossaram as tropas militares, os povos indígenas também foram os braços que forneceram seu sustento.

Authors: Oeste Laura
Published: January 2024

Nesta escrita abordaremos alguns termos utilizados para mulheres indígenas encontrados na documentação da América hispânica da segunda metade do Setecentos. Organizamos a análise a partir de relatos de pessoas raptadas na região do Prata, como é o caso de Juana Aragón, mulher que se apresenta como índia criolla e identifica as demais como chinas. A partir das fontes percebemos uma forma diversa de usos e manejo de situações que demonstram a ambiguidade das nomenclaturas e identidades envolvidas nesses espaços fronteiriços, estando sua utilização relacionada ao contexto e as pessoas envolvidas.
Queer, Trans, Elected
Authors: Goodman Michael A. , Cohen Sarah Simi , Gonzalez Sergio A.
Published: January 2024

This chapter highlights the story of LGBTQIA+ students in elected student government, as well as the ways their identities are constantly at play in these elected roles and campus spaces. This chapter contains three distinct sections: (1) Relevant literature on LGBTQIA+ individuals in student involvement and governance, (2) notable “firsts” and historical contexts, and (3) support systems and structures for LGBTQIA+ students in student government. The final section of the chapter serves as a ‘roadmap' for student affairs administrators and student government advisors to better/best support queer and trans students in this functional area of student involvement.
LGBTQIA International Student Experience
Authors: Herridge Andrew S. , Nkaleke Dennis Iziogo
Published: January 2024

This chapter explores how LGBTQIA international students studying in the United States engage with the campus community and their experiences based on the identities they hold. While the transition to postsecondary education can be challenging for any international student, the intersecting identity of also identifying as a member of the LGBTQIA community increases the challenges faced by international students. LGBTQIA international students must navigate a new university campus environment while also taking into account the identities they hold. The findings indicate that LGBTQIA international students tend to experience a concern for their safety and feelings of isolation. The results of this study provide insights into the ways in which postsecondary institutions can better support LGBTQIA international students.
Exploring Multiple Jeopardy in Science, Technology, Engineering, and Mathematics (STEM) Education
Authors: Rosales Martin R. , Ackerman Jennifer R.
Published: January 2024

Queer international students in STEM face barriers to success in and out of the classroom. By holding multiple marginalized identities, power dynamics shift, and students often feel like they do not belong. International queer invisibility is reinforced daily, where their voices are not heard and additional barriers to success are present. This is in direct contrast to their white, heterosexual male counterparts who are often in the majority either as peers or as faculty. This chapter explores the intersection of multiple marginalized identities in STEM education that exacerbates systemic issues found within. Utilizing multiple frameworks such as intersectionality, acculturation, neo-racism, STEM identity development, and queer theory, this chapter aims to highlight the multiple jeopardy faced by queer international students and offer recommendations for practitioners to better support students in STEM.
Solid Polymer Electrolyte (SPE) from Corn Starch and Aluminum Nitrate Salt Composites for Aluminum - ​​Ion Battery

Published: January 2024

The increasing of need for portable electrical energy makes the demand for rechargeable batteries high. Aluminum-ion battery with Solid Polymer Electrolyte (SPE) produced from the natural polymer corn starch with salt additive has the potential to be developed. The flexibility and resilience of SPE are enhanced by glycerol (C3H8O3). Throughing gelatinization of the linear monomer chains to become amorphous, the space for the ions in it is more free so that the ionic conductivity is high. By means of solution casting, heating temperature of 50°C for 9 hours found SPE with a strong structure. With the same concentration CS-Al has a higher conductivity with σ = 4.93 x 10-5 S/cm than CS-Na whose value is σ = 2,92 x 10-5 S/cm. This is due to the SPE CS-Al show more amorphous structure which allow more flexible ionic segmental motion. This is in accordance with XRD resulting which shows that the addition of aluminum nitrate salt is more amorphous than sodium acetate; the shift in peak pattern is also greater due to cation intercalation Al3+ with corn starch. FTIR is the result found that nitrate fixed by corn starch, indicated a change in the hydroxyl group of corn starch amylopectin. SEM photo of result also showed aluminum nitrate salt ion more easily in overcoming than sodium acetate. The indicate of SPE was more homogeneous because corn starch was already intercalated. They are combined to Al3+ and NO3- ions. With this value it can be an appropriate reference for developing SPE on Aluminum-ion batteries with aluminum nitrate salts have higher performance and environment friendly Keywords: Aluminum-ion battery, Solid Polymer Electrolyte, corn starch, ionic conductivity, and Amorphous
