Authors: Han Ji Min , Cho Jung Hwan , Kim Hye In , Suh Sunghwan , Lee Yu-Ji , Lee Jung Won , Kim Kwang Min , Bae Ji Cheol
Published: July 2023

Background: Fatty liver is associated with increased risk of developing type 2 diabetes. We aimed to evaluate whether the severity of hepatic steatosis is associated with incident diabetes.Methods: We conducted a longitudinal analysis using data from 1,798 participants who underwent a comprehensive health checkup and abdominal computed tomography (CT). We assessed the association between baseline liver attenuation value on non-contrast CT images and risk of incident diabetes. All the participants were categorized into three groups based on the baseline liver attenuation value on non-contrast CT images: without hepatic steatosis (>57 Hounsfield unit [HU]), mild hepatic steatosis (41–57 HU), and moderate to severe hepatic steatosis (≤40 HU).Results: During a median follow-up period of 5 years, 6.0% of the study participants progressed to diabetes. The incidence of diabetes was 17.3% in the moderate to severe hepatic steatosis group, 9.0% in the mild steatosis group, and 2.9% in those without hepatic steatosis. In a multivariate adjustment model, as compared with participants without hepatic steatosis, those with moderate to severe steatosis had a hazard ratio (HR) of 3.24 (95% confidence interval [CI], 1.64 to 4.2) for the development of diabetes, and those in the mild steatosis group had a HR of 2.33 (95% CI, 1.42 to 3.80). One standard deviation decrease in mean CT attenuation values of the liver was associated with a 40% increase in the development of diabetes (multivariate adjusted HR, 1.40; 95% CI, 1.2 to 1.63).Conclusion: We found a positive association between severity of hepatic steatosis and risk of incident diabetes. Greater severity of steatosis was associated with a higher risk of incident diabetes.
Review of Frederick Mawusi Amevenku and Isaac Boaheng, “Biblical Exegesis in African Context”
Authors: Wandusim Michael F.
Published: July 2023

The book has nine chapters plus an introduction and concluding remarks with a foreword by Daniel Nii Aboagye Aryeh (PhD). Its content can be divided into two thematic parts. The first part, covering chs. 1–5 (pp. 1–42) is described variously as “elements of biblical interpretation” (p. xv), “foundational principles” (p. xv), and “basic elements of Biblical Exegesis” (p. 41). The authors signal this division by indicating in the “Introduction” (pp. xv-xvi) that “Most of the chapters examine elements of biblical interpretation …. Some of them include textual analysis, socio-rhetorical interpretation, contextual analysis, and others. We believe that these elements serve as foundational principles upon which African biblical interpretation can be built” (p. xv). This is further specified in the conclusion of ch. 5 “Literary Analysis” where the authors conclude that “This chapter has brought to an end our discussions on the basic elements of Biblical Exegesis. Most of the things discussed in the chapters that follow are applications of these elements” (p. 41). Accordingly, it is to be taken that chs. 6–9 (pp. 43–108) form the second thematic part of the book dealing with African biblical interpretation. Yet the place of ch. 6 “Socio-Rhetorical Biblical Interpretation” (pp. 43–58) is initially confusing because, while it is considered as part of the “elements of biblical interpretation” (p. xv) in the introduction and in the concluding remarks (p. 109), the ending of ch. 5 quoted shortly above indicates that those basic exegetical elements end with literary analysis and the subsequent chapters starting with ch. 5 are the application of these elements. The needed structural clarity here is missing and the reader is left to figure it out by him/herself in light of the remarks in the introduction and conclusion.
Exploring the Extremes: Characterizing a New Population of Old and Cold Brown Dwarfs
Authors: Meisner Aaron M. , Leggett S. K. , Logsdon Sarah E. , Schneider Adam C. , Tremblin Pascal , Phillips Mark
Published: July 2023

Mapping out the populations of thick disk and halo brown dwarfs is important for understanding the metallicity dependence of low-temperature atmospheres and the substellar mass function. Recently, a new population of cold and metal-poor brown dwarfs has been discovered, with T
eff ≲ 1400 K and metallicity ≲−1 dex. This population includes what may be the first known “extreme T-type subdwarfs” and possibly the first Y-type subdwarf, WISEA J153429.75−104303.3. We have conducted a Gemini YJHK/Ks photometric follow-up campaign targeting potentially metal-poor T and Y dwarfs, utilizing the GNIRS and Flamingos-2 instruments. We present 14 near-infrared photometric detections of eight unique targets: six T subdwarf candidates, one moderately metal-poor Y dwarf candidate, and one Y subdwarf candidate. We have obtained the first-ever ground-based detection of the highly anomalous object WISEA J153429.75−104303.3. The F110W − J color of WISEA J153429.75−104303.3 is significantly bluer than that of other late T and Y dwarfs, indicating that WISEA J153429.75−104303.3 has an unusual spectrum in the 0.9–1.4 μm wavelength range which encompasses the J-band peak. Our J-band detection of WISEA J153429.75−104303.3 and corresponding model comparisons suggest a subsolar metallicity and temperature of 400–550 K for this object. JWST spectroscopic follow-up at near-infrared and mid-infrared wavelengths would allow us to better understand the spectral peculiarities of WISEA J153429.75−104303.3, assess its physical properties, and conclusively determine whether or not it is the first Y-type subdwarf.

We present follow-up photometric observations and time-series analysis of a nova-like, SW Sextans-type, cataclysmic variable (CV) candidate, LAMOST J204305.95+341340.6 (hereafter J2043+3413), with a Gaia G-band magnitude of 15.30 and a distance of 990 pc, which was identified from the LAMOST spectrum. The photometric data were collected with the Tsinghua-NAOC 0.8 m telescope (TNT), Transiting Exoplanet Survey Satellite (TESS), Zwicky Transient Facility (ZTF), and ASAS-SN. The TESS light curve reveals the presence of two prominent periods of 2.587(8) hr and 1.09(5) days, corresponding to the orbital and superorbital (precession) period, respectively. The TNT data obtained in 2020 shows a possible quasiperiodic oscillation of 1426 s. The precession period is about three times shorter than that of CVs with similar orbital periods, indicating an unusually fast precessing accretion disk. The ZTF data is found to show a sudden decline of ∼0.4 mag on MJD 58979. From the intermittent behavior of the eclipse, we deduce that J2043+3413 is an intermediate inclination system of CV, similar to V795 Her, which is also situated in the period gap.
Search for Young and Intermediate-age Stellar Populations in the Galactic Center with Subaru/MOIRCS and CO Narrowband Filters
Authors: Nishiyama Shogo , Funamoto Naoya , Schödel Rainer
Published: July 2023

Extinction toward the Galactic Center (GC) is extreme and limits observations of its stars to the infrared. In addition, the extinction varies on scales of arcseconds. It is therefore highly challenging to distinguish between different stars photometrically and to identify young, massive, or intermediate-age stars that can trace recent star formation. Here we report the results of near-infrared imaging observations of a

region at the GC that encompasses the northwest part of the nuclear star cluster and parts of the nuclear stellar disk. We carried out the observations with the wide-field camera MOIRCS of the Subaru Telescope, using three narrowband (NB) filters. Two of the filters trace the stellar continuum, while we use the third one to measure the strength of the CO absorption features that are prominent in the spectra of cool giants, shallower in the spectra of warmer stars, and absent in young massive stars. Thus, we aim to distinguish between old late-type giants and young and intermediate-age stars. We have found 131 candidates of young and intermediate-age stars. The magnitude limit is ≈11.25 in the extinction-corrected K-band magnitude. The contamination of the candidates by old giants is estimated to be 26%. We show that our method allows us to identify correctly four out of five spectroscopically confirmed massive stars, and 68 of 75 spectroscopically confirmed cool stars (91%). Our results suggest that imaging observations with a CO NB filter can be complementary to other methods to identify massive stars in the GC.
A UFO Seen Edge-on? Resolving Ultrafast Outflow Emission on ∼200 pc Scales with Chandra in the Active Nucleus of Mrk 34

Published: July 2023

We present Chandra ACIS imaging spectroscopy of the nucleus of the Seyfert 2 Galaxy Mrk 34. We identify spatially and spectrally resolved features in the band that includes Fe Kα, Fe xxv, and Fe xxvi. These features suggest high-velocity (≳15,000 km s−1 line-of-sight) material spanning ∼0.″5, within ∼200 pc of the nucleus. This outflow could have deprojected velocities ∼12–28× greater than the [O iii]-emitting outflows, and could potentially dominate the kinetic power in the outflow. This emission may point to the origins of the optical and X-ray winds observed at larger radii, and could indicate a link between ultrafast outflows and AGN feedback on ≳kiloparsec scales.
High-density Reflection Spectroscopy of Black Hole X-Ray Binaries in the Hard State

Published: July 2023

We present a high-density relativistic reflection analysis of 21 spectra of six black hole X-ray binaries in the hard state with data from NuSTAR and Swift. We find that 76% of the observations in our sample require a disk density higher than the 1015 cm−3 assumed in the previous reflection analysis. Compared with the measurements from active galactic nuclei, stellar mass black holes have higher disk densities. Our fits indicate that the inner disk radius is close to the innermost stable circular orbit in the luminous hard state. The coronal temperatures are significantly lower than the prediction of a purely thermal plasma, which can be explained with a hybrid plasma model. If the disk density is fixed at 1015 cm−3, the disk ionization parameter is overestimated while the inner disk radius is unaffected.
A Quantum-mechanical Treatment of Electron Broadening in Strong Magnetic Fields
Authors: Gomez Thomas A. , Zammit Mark C. , Fontes Christopher J. , White Jackson R.
Published: July 2023

Spectral line-shape fitting is an extremely useful tool in determining the gravity of white dwarf stars. This method is so far limited to nonmagnetic white dwarfs largely because the theory of line broadening in high magnetic fields is not as complete as in the nonmagnetic case. Current Stark+Zeeman models treat plasma particles classically and ignore the motion of the nucleus. We develop the formalism for a quantum-mechanical treatment of the perturbing electrons and include the nuclear motion as part of the broadening and explore their relative importance. The conditions we explore are those found in white dwarf and neutron star atmospheres. We find that, contrary to previous studies, the quantized perturbing electrons create more broadening than perturbers on a straight-path trajectory. Additionally, the quantization of the plasma electrons gives rise to resonances away from the line center. The nuclear motion creates an additional electric field, which also leads to an increase in line broadening; however, this effect in neutron star atmospheres is not as large as previously estimated. This suggests that neutron star spectral lines are sensitive to density and that their mass and radius can be obtained from spectral line fitting, which would help constrain the neutron star equation of state.
Discovery of an Extended γ-Ray Emission around the Supernova Remnant Candidate Associated with PSR J0837–2454
Authors: Zhang Pengfei , Xin Yuliang
Published: July 2023

Motivated by the recent discovery of a low-surface-brightness diffuse emission, a supernova remnant (SNR) candidate, surrounding the young pulsar PSR J0837–2454, we carry out a likelihood analysis of the γ-ray data obtained by the Fermi Gamma-ray Space Telescope from 2008 August to 2022 November. Using a 2D Gaussian spatial template, we detect a significant extended γ-ray emission with a 68% containment radius of ∼1.°8, which is spatially coincident with the new SNR candidate at the ∼12σ confidence level. The spectrum of the extended γ-ray emission, obtained in the energy range of 0.1-500.0 GeV, shows a significant spectral curvature at ∼1 GeV, with a log-parabola spectral shape. Several scenarios, such as an SNR, pulsar wind nebula, and pulsar halo, are discussed as the potential origins of the extended γ-ray emission, and our model fitting results are preferred for the SNR scenario.
Analysis of small oscillations of a pendulum partially filled with a viscoelastic fluid
Authors: Essaouini Hilal , Capodanno Pierre
Published: July 2023

This paper focuses on the spectral analysis of equations that describe the oscillations of a heavy pendulum partially filled with a homogeneous incompressible viscoelastic fluid. The constitutive equation of the fluid follows the simpler Oldroyd model. By examining the eigenvalues of the linear operator that describes the dynamics of the coupled system, it was demonstrated that under appropriate assumptions the equilibrium configuration remains stable in the linear approximation. Moreover, when the viscosity coefficient is sufficiently large the spectrum comprises three branches of eigenvalues with potential cluster points at $ 0 $, $ \beta $ and $ \infty $ where $ \beta $ represents the viscoelastic parameter of the fluid. These three branches of eigenvalues correspond to frequencies associated with various types of waves.
Fredholm inversion around a singularity: Application to autoregressive time series in Banach space
Authors: Seo Won-Ki
Published: July 2023

This paper considers inverting a holomorphic Fredholm operator pencil. Specifically, we provide necessary and sufficient conditions for the inverse of a holomorphic Fredholm operator pencil to have a simple pole and a second order pole. Based on these results, a closed-form expression of the Laurent expansion of the inverse around an isolated singularity is obtained in each case. As an application, we also obtain a suitable extension of the Granger-Johansen representation theorem for random sequences taking values in a separable Banach space. Due to our closed-form expression of the inverse, we may fully characterize solutions to a given autoregressive law of motion except a term that depends on initial values.
El Memorial de Gonzalo Solís de Merás sobre la conquista de Florida: problemas de autoría y redacción
Authors: Arbesú David
Published: July 2023

En el presente artículo se lleva a cabo un análisis del llamado Memorial de Gonzalo Solís de Merás para argumentar que es imposible que dicha persona fuese, al menos en solitario, su autor. La atribución a Solís de Merás, basada en una única referencia de principios del siglo XVIII, viene desmentida por la propia narrativa, donde no aparece ni una sola mención al autor ni hay referencias en primera persona. Más importante es el hecho de que el supuesto autor, a quien la crítica ha imaginado escribiendo el Memorial sobre el terreno y a raíz de los sucesos, no pudo ser testigo de los eventos acaecidos en las últimas tres cuartas partes de la obra.

Este artículo propone conocer y comprender de qué modo se desarrollaban los procesos en la justicia diocesana entre agentes del clero, y sus ideas acerca de la iglesia, la religiosidad y el poder, así como las distintas estrategias esgrimidas durante un pleito por las partes implicadas. Se estudia el litigio seguido por el convento dominico de San Miguel de Tucumán contra el vicario foráneo local por la posesión de la cofradía del Santísimo Rosario, entre 1772 y 1792, analizando desde la perspectiva jurisdiccionalista a una corporación no estudiada hasta el momento, a partir de fuentes inexploradas.
De muchas jurisdicciones a una sola soberanía: la abolición del fuero eclesiástico en Venezuela (1811-1812)
Authors: García Pérez Rafael D.
Published: July 2023

La supresión del privilegio del fuero eclesiástico establecido en el artículo 180 de la Constitución de Venezuela de 1811 supuso el primer paso en el desmantelamiento del entramado jurisdiccional propio del período virreinal y la entronización del principio de igualdad exigido por la soberanía del Estado. Esta medida enfrentó al clero con la naciente república y dio lugar, con motivo de los terremotos de 1812, a una fuerte propaganda anti republicana por parte de ese mismo clero que culminaría con la desaparición de la primera república de Venezuela.
El Baile de la Conquista de Quetzaltenango, un drama del regionalismo histórico guatemalteco del siglo XIX
Authors: Castillo Víctor , Cossich Vielman Margarita
Published: July 2023

Entre los académicos ha existido un debate sobre el origen del guatemalteco el Baile de la Conquista, con posturas que fechan la composición del drama ya sea para siglo XVI como parte del teatro evangelizador, o bien como ejemplar del romanticismo nacionalista del siglo XIX. Proponemos que el Baile de la Conquista fue representado únicamente desde la segunda mitad del siglo XIX como un performance que podía ser apropiado de maneras diferentes por audiencias diversas en el contexto de proto-nacionalismos emergentes en Guatemala.

Une des conséquences les plus manifestes de la conquête des Gaules fut sans conteste le passage de la monnaie gauloise à la monnaie romaine. Jusqu'à présent, aucune étude détaillée n'y avait pourtant été consacrée. En confrontant les données numismatiques aux sources archéologiques, littéraires et épigraphiques, et en s'appuyant sur plus d'une centaine de cartes et de graphiques produits spécialement pour cette recherche, cet ouvrage propose une analyse croisée de la monétarisation et de la romanisation dans la Gaule du Nord et de l'Est. Replacée dans son contexte économique, politique et social, la monnaie éclaire l'ensemble des processus qui ont mené à l'intégration des Trois Gaules dans le monde romain, depuis l'apparition d'une économie monétaire avec les premières monnaies gauloises du IIIe s. a.C. et les traités d'alliance entre Rome et peuples gaulois au IIe s. a.C., jusqu'à la conquête césarienne et la municipalisation augustéenne qui signe l'arrêt des frappes indigènes et leur disparition complète dès le milieu du Ier s. p.C.
L’Exposition Universelle de 1900 et le voyage Barcelone - Paris
Authors: Freixa Mireia
Published: July 2023

L’Exposition Universelle de 1900 de Paris revêt une importance particulière pour sa contribution à la diffusion de l’Art nouveau, un style que l’on perçoit pourtant davantage dans la rue que dans les pavillons officiels de l’Exposition construits encore dans un style éclectique. Le pavillon espagnol de José de Urioste devient la référence de la nouvelle architecture régionaliste d’Espagne mais cet événement a exercé une influence relative sur l’art et l’architecture en Catalogne car la modernité s’était déjà engagée une dizaine d’années auparavant, sur la voie de ce qu’on a appelé le « premier modernisme », depuis l’Exposition Universelle de Barcelone de 1888. Mais l’exposition de Paris exerce un énorme pouvoir d’attraction sur les artistes et les intellectuels catalans et sensibilise la culture catalane à l’esprit cosmopolite et devient surtout un modèle de ville – grande métropole européenne – dont Barcelone se veut être le reflet. La recherche a été faite à partir de matériaux qui attestent du succès de l’événement : catalogues, cartes postales, brochures touristiques, lettres et documents personnels, conservés dans des archives et avec le magazine hebdomadaire Pèl & Ploma.
París a Barcelona, vista i exposada pels modernistes catalans
Authors: Sala Teresa-M.
Published: July 2023

À la fin du XIXe siècle, Paris est à l’origine d’un flux impressionant de paroles et d’images démultipliées. L’article présente les principaux artistes modernistes catalans ayant vécu la bohème à Paris et l’ayant faite voir à Barcelone. Santiago Rusiñol et Ramon Casas y montrent la peinture moderne de la capitale française. Le public barcelonais découvre les sujets de la mythologie montmartroise, un paysage urbain tout à fait distinctif et la vie detraquée des femmes et des artistes. Une seconde géneration commence à éclore à la fin des années 1890 et au tout début du XXe siècle, celle qui fréquente notamment Els Quatre Gats. Isidre Nonell et Ricard Canals arrivent à Paris en 1897 suivis par Pablo Picasso, Carles Casagemas et quelques autres artistes, avec l’unique présence d’une peintre, Lluïsa Vidal.
Vestir la pintura: el mite de «la parisenca» i Ramon Casas
Authors: Aragonès Riu Núria
Published: July 2023

Depuis la deuxième moitié du XIXe siècle nous assistons à la construction du « mythe » de la Parisienne en tant qu’icône de mode et de modernité dans les arts et la littérature. Quelques peintres et dessinateurs du modernisme catalan, notamment Ramon Casas, adoptèrent le motif iconographique de la jeune femme parisienne et s’en servirent comme source d’inspiration pour habiller les femmes qui peuplaient leurs illustrations. Notre but ici est d’approcher les rapports que ces peintres entretinrent avec la mode dans le cadre de leur création artistique et d’en faire ressortir l’influence du modèle parisien.

L’article revisite la question de l’ancrage territorial des coopératives au prisme d’un cadre d’analyse croisant la sociologie du travail politique et l’approche régulationniste « méso ». Ce cadrage général est mis à l’épreuve à partir d’une étude de cas portant sur les coopératives de production (SCOP) du Pays basque français, considérées comme un mouvement social économique aspirant à refonder le développement local sur une base coopérative, territoriale et intersectorielle. Les visions du développement territorial ainsi véhiculées ne sont cependant pas statiques. Nous en proposons dès lors une lecture sociohistorique en distinguant trois séquences. La genèse du mouvement, d’une part, se caractérise dans les années 1970 par sa politisation, les fondateurs des SCOP se référant à un modèle de développement économique endogène, au modèle transfrontalier de Mondragón, à l’identité territoriale et à des registres hérités de coopération. Dans une deuxième phase, le mouvement connaitra un ralentissement dû à quelques échecs entrepreneuriaux. Les contraintes sectorielles et marchandes mettent alors à l’épreuve le modèle coopératif et l’inter-coopération. Une troisième phase, à compter des années 2000, voit un redéploiement des coopératives dans le cadre d’un spectre élargi de mobilisations citoyennes autour de l’économie sociale et solidaire mais aussi de la transition écologique, de la langue et de la culture basques, ce redéploiement coïncidant avec un changement substantiel de la gouvernance territoriale. La section conclusive revient sur quelques enseignements à portée générale concernant l’ancrage territorial des coopératives.
Analyser la politique économique à partir de facteurs sociaux
Authors: Eloire Fabien , Dallery Thomas
Published: July 2023

L’article montre l’intérêt d’une approche interdisciplinaire pour analyser la prise de décision en matière de politiques économiques. Il prend appui sur l’exemple du « tournant de la rigueur » en France, opéré en 1983 par le gouvernement socialiste. Cet épisode demeure encore, 40 ans plus tard, une référence incontournable des débats politiques relatifs à l’exercice du pouvoir par les forces de gauche. Au travers de l’étude des fonds d’archive des conseillers de l’Élysée et de données macroéconomiques, l’article donne à voir l’évolution de la controverse entre partisans de la relance et avocats de la rigueur, en précisant les stratégies suivies par ces derniers pour emporter l’adhésion du président Mitterrand. Le « tournant » de la rigueur n’apparaît alors ni comme le seul produit de circonstances économiques (contrainte extérieure) imposant ce choix, ni comme le seul fruit d’une conversion idéologique (néolibérale) des gouvernants, ni enfin comme la seule conséquence d’un travail relationnel d’un front de conseillers, mais comme le produit de ces différentes causes.
Coopératives de production : quelle spécificité du rapport social d’activités coopératif à l’aune du rapport salarial ?
Authors: Ballon Justine , Celle Sylvain , Fretel Anne , Vallade Delphine
Published: July 2023

Cet article analyse les coopératives de production en questionnant leur capacité à produire un rapport social d’activités relativement autonome et protecteur vis-à-vis du rapport salarial dominant. En prenant appui sur les travaux régulationnistes consacrés au rapport salarial et au rapport social d’activité, nous proposons une lecture basée sur la conceptualisation d’un « rapport social d’activités coopératif » spécifique, fondé sur le principe de double qualité. Il se caractérise par quatre composantes principales : 1) la futurité ; 2) la gouvernance ; 3) l’organisation du travail ; 4) les revenus et mutualisations. À travers une relecture historique et la mise en lumière de faits stylisés, nous considérons l’évolution historique du « rapport social d’activités coopératif » dans les coopératives de production en France, au regard de l’évolution du rapport salarial. Trois principales périodes sont dégagées : 1815-1910 avec un « rapport social d’activités coopératif » alternatif à l’émergence du salariat ; 1910-1980 avec son assimilation dans la société salariale ; enfin à partir des années 1980 avec le retour d’un idéal contournant la subordination salariale. Au regard de cette lecture théorique et historique du « rapport social d’activités coopératif », nous questionnons sa capacité à produire des formes de protection et de sécurisation salariale au sein de l’entreprise face à un rapport salarial de plus en plus précaire. Nous mettons finalement en discussion le fait que la gouvernance démocratique serait non seulement un élément clé de différenciation du « rapport social d’activités coopératif », mais aussi une condition pour produire une protection salariale dans l’entreprise.
La convention d’identité coopérative : création de compromis sectoriels et territoriaux
Authors: Artis Amélie , Filippi Maryline , Petrella Francesca
Published: July 2023

Alors que l’entreprise reste une institution majeure, l’entreprise coopérative demeure encore relativement peu étudiée malgré sa contribution significative et durable aux systèmes économiques. Nous proposons de l’aborder à partir d’une convention d’identité coopérative fondée sur la propriété collective et la gouvernance démocratique. À partir de différentes études de cas, nous dégageons les propriétés de cette convention d’identité coopérative et la manière dont elles entrent potentiellement en tension avec les contraintes sectorielles et territoriales. L’originalité de notre apport réside dans l’analyse de cette convention d’identité coopérative et dans la compréhension de ses ajustements et compromis, à travers une grille analytique, au croisement des logiques sectorielles et territoriales. Notre conceptualisation s’inscrit dans la perspective d’une singularisation de l’entreprise coopérative dans une lecture institutionnaliste.

The media, governments, and academics throughout the world are focusing progressively on social entrepreneurship as it becomes an increasingly significant global phenomenon. Similarly, the past literature declares that firm’s approaches to social responsibility could vary, but they always place a greater emphasis on satisfying and shaping the expectations of stakeholders. In a similar vein, it is evident that organizations face a unique problem that goes far beyond balancing their interests and demands with those of their stakeholders. Thereby, the underlaying aim of this study is to explore the role of stakeholder pressure interventions in social entrepreneurship. Further, this paper shed light on the future growth of the stakeholder pressure in social enterprise research agenda and how to entice new researchers to participate to it. This is primarily a conceptual study using a qualitative approach to the topic at hand. A comprehensive literature review and the considerations garnered from informants given. According to our views, the conceptual and empirical scope of the stakeholder pressure in social entrepreneurship area must be redefined and further explored. The insights discussed in this paper aid in resolving and explaining some of the arguments and conceptual and practical obstacles that have impeded the growth of the stakeholder pressure in social enterprise research agenda.
Study of mosquito (Culicidae) larvae and characterisation of water bodies in urban and periurban areas

Urbanisation has modified the distribution and community composition of mosquito species (Culicidae). Habitat disturbance may increase the risk of loss of species diversity and the occurrence of vector-borne diseases. Studies on the presence of larvae and the eco-physicochemical characteristics of water bodies near urban areas provide information on the risk of these diseases. In this study, the presence of larvae in different types of urban and periurban water bodies in Villahermosa City, Tabasco, Mexico was analysed. The eco-physicochemical characteristics of each collecting site were measured. A total of 67 528 larvae were collected, 1366 were identified to species, and 15 species were observed. Although Culex spp. were the most dominant species, Anopheles albimanus was the only species present in all habitats. Despite the large variability in the parameters measured (especially in physicochemical parameters; e.g., pH, electrical conductivity, total dissolved solids), differences were observed among the breeding sites. Weak correlations were found between eco-physicochemical parameters and species presence. Predators may have a major role in determining community processes in the region. Habitat disturbance may be responsible for eco-physicochemical variations altering mosquito community composition, resulting in the loss of endemic mosquito species and increasing the risk of vector-borne diseases in Villahermosa.
System Safety for Vertical Flight
Authors:   Sikorsky Aircraft, Hewitt John
Published: July 2023

The field called System Safety evolved to satisfy the demand for an organized approach to safety management of complex new aerospace systems being developed in the 1960s. As technology has advanced and complexity has increased, its application spread to aviation, rail transportation, weapons, nuclear power, medical devices, oil and gas production, and almost every area of life where complex systems could lead to events having high consequences. System Safety is often defined as the application of engineering and management principles, criteria, and techniques to achieve acceptable mishap risks within the constraints of operational effectiveness, time, and cost throughout all phases of the system life cycle. The International System Safety Society states that for almost any system, product, or service, the most effective means of limiting product liability and accident risks is to implement an organized system safety function beginning in the conceptual design phase, and continuing through to its development, fabrication, testing, production, use, and ultimate disposal.

This paper presents research addressing the technological gap in the predictive capabilities of modern computational fluid-structures interaction (FSI) in the context of the US Navy's requirement for accurate loads prediction for both critical rotor head and fuselage components in the context of a real aircraft's fatigue life tracking program, with the ultimate objective of loads accuracy and performance robust enough to support near real-time lifing assessments across the full flight regime. This research, funded via US Navy STTR N17A-T009, touches on a broad range of innovative research areas, starting with application of the Load Confluence Algorithm (LCA) to a coupled main rotor-fuselage/tail rotor model for the UH-60A. This paper will document research to date, extending beyond traditional approaches such as the main rotor analyzed in isolation or a fuselage model affected only by the inflow generated via an actuator disk model of the main rotor. This includes the development of use of modal super elements (MSEs) to model more complex rotorcraft components, such as the fuselage for use in main rotor loads simulations, as well as the stationary and rotating swashplates, and the rotating scissors. This paper will also document advances made in geometry modeling and mesh generation, computational mechanics of fluids and structures, modeling of coupled multi-physics phenomena, and high-performance computing, with improved representation of complex geometry and multi-physics phenomena. Lastly, these enhanced whole aircraft loads prediction methods will be examined within the context of future application to a structural fatigue life tracking program, in terms of accuracy, usability, and application performance.
Experimental Evaluation of Ice Accretion on Coaxial-rotor Vehicles
Authors:   Pennsylvania State University, Yan Sihong , Scroger Shawn , Palacios Jose
Published: July 2023

Coaxial-rotor configurations are being implemented on large-scale helicopters and commercial unmanned aerial systems (UAS). The performance of coaxial-rotor configuration in icing condition is not fully understood and further evaluation is needed. The goal of this research was to develop testing beds and methodologies to evaluate Two coaxial rotor test systems. Two test rigs were designed and fabricated in the Adverse Environment Rotor Test Stand at the Pennsylvania State University. One system has a coaxial configuration using 0.4 m diameter rotors, while the second one has a rotor diameter of 1.4 m. The power growth rate and thrust decline rate were quantified for both rotors. The average liquid water content of tests was 1.5 g/m3 and the median volume diameter was 20 µm. Tests were conducted under two temperatures,-5°C and-10°C. The upper rotor in the coaxial configuration worked as an icing shield for the lower rotor, as it collected a large majority of the incoming water droplets. At 3000 rpm, the power growth rate of the upper rotor was 23.4% greater than that of lower rotor. At 4000 rpm, the power growth rate of the upper rotor was 53.8% higher than that lower rotor in-5°C. At-10°C, the percentage difference of 4000 rpm was 48.3%. The shielding effect of the upper rotor is positively related to rotor speed. The thrust of the upper rotor also decreased in icing cloud and the thrust of the lower rotor was not affected by the ice accretion. The thrust decline rate of cases at 3000 rpm and-5°C was 0.07 N/s. The decline rate of 4000 rpm at-5°C and-10°C were 0.08 N/s and 0.18 N/s. The difference in torque between the rotors leads to imbalances that negatively affect the maneuverability of a coaxial-rotor vehicle. The shedding event was observed on the dual-layer stand and introduced imbalanced loads to the system. The torque imbalance due to shedding could potentially be controlled by increasing rpm.
