Published: March 2022

This article aims to determine the position of the privately made deed and notarial deed. In this case, the District Court Decision Number 738 / Pdt.6 / 2016 / PN.Sby stated that the deed of sale and purchase was canceled between Mrs. Hierawati and Mrs. Maria Magda. The District Court's decision is corroborated by the Decision of the High Court Number 83 / PDT / 2018 / PT. SBY. A sale and purchase deed from a notary is an authentic deed that has perfect and binding proof power (Article 1867 KUHPer), while the evidentiary power of a privately made deed is lost if denied by the party. In this case, the defendant does not acknowledge the contents of the statement. In accordance with the jurisprudence from the Supreme Court of the Republic of Indonesia Number 167 K / SIP / 1959, it is stated that a privately made deed is a binding proof is its content is acknowledged by the party. However, if a privately made deed is denied by one of the parties, it lost its evidentiary power. A sale and purchase deed from a notary cannot be canceled by a statement which is a privately made deed.

Published: March 2022

Dalam praktek hukum bisnis di Indonesia, banyak terjadi kerjasama antara swasta dengan instansi pemerintah dalam hal pengelolaan aset, salah satu perjanjian yang paling sering digunakan adalah Memorandum of Understanding (selanjutnya disebut dengan MoU) atau yang disebut juga Perjanjian Pendahuluan. Perjanjian ini digunakan sebagai komitmen awal untuk mencapai suatu perjanjian pokok bagi para pihaknya. Ada beberapa pendapat hukum yang berbeda mengenai kekuatan hukum dari perjanjian pendahuluan, diantaranya adalah Gentlement Agreement dan Agreement is agreement. Putusan Mahkamah Agung Nomor:501K/Pdt/2014 antara PT. SSLL (selanjutnya disebut SSLL) sebagai pihak yang dinyatakan sebagai pemenang tender untuk pengelolaan Gedung Indo Plaza milik PT. KAI (selanjutnya disebut KAI) selama 30 tahun. KAI yang memutus MoU dengan SSLL sebelum KSO terbit digugat atas dasar wanprestasi. Dalam putusan ini dapat dilihat pertimbangan pengadilan dalam menentukan letak kesepakatan awal sebagai dasar adanya suatu perjanjian serta fungsi MoU sebagai instrumen untuk mencapai suatu prestasi.

Authors: Kumar P. , Dharaniswari K.
Published: March 2022

The paper emphases on the fight of women who aspire to be self-governing, achieve different position for herself and to get education, freedom and identity in the society. ManjuKapur's A Married Woman highlights Astha's fight and existence as a new woman maintaining on liberation from patriarchal social arrangement and thinking. She appears as a free woman, destroying the chain of tradition. Kapur thus represents the woman from different angle by placing her in the midst of socio-economic struggles. During her life she preserves a long silence to domestic violence and traditional values that is approved from one generation to another. But, nowadays, she has released her eyes wide enough to see the world through her own viewpoints and raises her voice in the world to protest against the male dominant society. She is a symbol of backgrounds which is nourished with traditional values to become a sacrificial daughter, a wife and a mother. She knows her privileges in life and is aware of the balance she has to continue in life.

On July 1 and July 26 2017 there was a simultaneous trip of PLTDG Units 1,2,5,5,6,7,8 and PLTDG Units 1,3,4,5,6,7,8,9 due to a momentary drop voltage due to disturbance kites on the 150 KV line network sanur – gianyar. From the trip conditions, it shows that there is a problem with the generator unit equipment which causes PLTDG units 1,2,3,4,5,6,7,8,9 to trip due to a momentary drop voltage. From the results of the analysis, it is known that the unit trip was caused by a trip on the Pht Line 150 KV to the ship - Padang sambian on the Padang sambian side which resulted in a drop voltage on the low voltage side of 280.4 V or 29.9%. from Unominal. The trip limit of 200MW low-voltage PLTDG according to technical data is 351V or 12.3% of Unominal. The best option to solve the drop voltage fault solution is to install a 10KVA UPS on the LFO feeder pump power supply. The difference before and after the installation of the UPS feeder LFO is that before the installation of the low voltage UPS it drops to 280.4 V or 29.9% of Unominal, and the machine load drops to 11.6 MW. For the results after UPS installation there is no drop voltage value on the low voltage side which means that the UPS installation is successful as a voltage drop solution. So that the difference is obtained on the low voltage side of 119.6 V and on the engine load of 5 MW. Thus, the implementation of a UPS installation on a 200MW PLTDG is very important, in addition to supporting the reliability of the generator system and speeding up recovery in the event of a drop voltage, it can also be economically profitable, so that the company does not lose when the generating unit trips.

Runway is an airport facility which is very important for aircraft landing and taking off. The runway is a square area on the surface of the airport that is prepared for aircraft take off and landing, without a well-planned and managed runway, the aircraft will not be able to use the airport. In designing the runway, it is strictly regulated regarding the length, width, orientation (direction), configuration, slope / slope, and thickness of the runway pavement. This final project will analyze the feasibility of the runway length and the thickness of the pavement (runway) for the operational plan aircraft that will be used in the next 20 years. With ARFL corrections to the existing runway conditions, the current runway length is 2,500 meters. For the next 20 years traffic flow is forecasted using linear regression analysis from 2011 to 2037. From the forecasting results, it was found that the total aircraft movement was 19,138 movements (R1), so it was planned to use the B 737 900 ER aircraft because this aircraft had a passenger capacity of 220 seats. This aircraft is the reference for the planning of the runway dimensions. Some of the resulting planning analyzes include: the length of the planned runway is 2,498 meters long and 45 meters wide. Meanwhile, the pavement planning analysis resulted in a surface layer thickness of 4 inches, a base coarse layer of 13 inches, and a subbase thickness of 22 inches.

Stellar Mass-to-light Ratios: Composite Bulge+Disk Models and the Baryonic Tully–Fisher Relation
Authors: Schombert James , McGaugh Stacy , Lelli Federico
Published: March 2022

We present stellar population models to calculate the mass-to-light ratio (ϒ*) based on galaxies’ colors ranging from GALEX far-UV to Spitzer IRAC1 at 3.6 μm. We present a new composite bulge+disk ϒ* model that considers the varying contribution from bulges and disks based on their optical and near-IR colors. Using these colors, we build plausible star formation histories and chemical enrichment scenarios based on the star formation rate–stellar mass and mass–metallicity correlations for star-forming galaxies. The most accurate prescription is to use the actual colors for the bulge and disk components to constrain ϒ*; however, a reasonable bulge+disk model plus total color only introduces 5% more uncertainty. Full bulge+disk ϒ* prescriptions applied to the baryonic Tully–Fisher relation improve the linearity of the correlation, increase the slope, and reduce the total scatter by 4%.

We report the discovery of two Black Widow millisecond pulsars in the globular cluster (GC) M28 with the MeerKAT telescope. PSR J1824−2452M (M28M) is a 4.78 ms pulsar in a 5.82 hr orbit, and PSR J1824−2452N (M28N) is a 3.35 ms pulsar in a 4.76 hr orbit. Both pulsars have dispersion measures near 119.30 pc cm−3 and have low-mass companion stars (∼0.01–0.03 M
⊙) that do not cause strong radio eclipses or orbital variations. Including these systems, there are now five known black widow pulsars in M28. The pulsar searches were conducted as a part of an initial phase of MeerKAT’s GC census (within the TRAPUM Large Survey Project). These faint discoveries demonstrate the advantages of MeerKAT’s survey sensitivity over previous searches, and we expect to find additional pulsars in continued searches of this cluster.
Sizes of Lensed Lower-luminosity z = 4–8 Galaxies from the Hubble Frontier Field Program

Published: March 2022

We constrain the rest-UV size–luminosity relation for star-forming galaxies at z ∼ 4 and z ∼ 6, 7, and 8 identified behind clusters from the Hubble Frontier Fields (HFF) program. The size–luminosity relation is key to deriving accurate luminosity functions (LF) for faint galaxies. Making use of the latest lensing models and full data set for these clusters, lensing-corrected sizes and luminosities are derived for 68 z ∼ 4, 184 z ∼ 6, 93 z ∼ 7, and 53 z ∼ 8 galaxies. We show that size measurements can be reliably measured up to linear magnifications of ∼30×, where the lensing models are well calibrated. The sizes we measure span a >1 dex range, from <50 pc to ≳500 pc. Uncertainties are based on both the formal fit errors and systematic differences between the public lensing models. These uncertainties range from ∼10 pc for the smallest sources to 100 pc for the largest. Using a forward-modeling procedure to model the impact of incompleteness and magnification uncertainties, we characterize the size–luminosity relation at both z ∼ 4 and z ∼ 6–8. We find that the source sizes of star-forming galaxies at z ∼ 4 and z ∼ 6–8 scale with luminosity L as L
0.54±0.08 and L
0.40±0.04, respectively, such that lower-luminosity (≳−18 mag) galaxies are smaller than expected from extrapolating the size–luminosity relation at high luminosities (≲−18 mag). The new evidence for a steeper size–luminosity relation (3σ) adds to earlier evidence for small sizes based on the prevalence of highly magnified galaxies in high-shear regions, theoretical arguments against upturns in the LFs, and other independent determinations of the size–luminosity relation from the HFF clusters.
Insights into the Evolution of Five Isolated Galaxies
Authors: Mazzei P. , Rampazzo R. , Marino A. , Trinchieri G. , Uslenghi M. , Wolter A.
Published: March 2022

Galaxy evolution is believed to be conditioned by the environment. Isolated galaxies or galaxies in poor groups are an excellent laboratory to study evolutionary mechanisms where effects of the environment are minimal. We present new Swift-UVOT data in six filters, three in the ultraviolet (UV), of five isolated galaxies aiming at shedding light into their evolution. For all of our targets, we present new UV integrated fluxes, and for some of them also new UBV magnitudes. Our observations allow us to improve their multiwavelength spectral energy distributions, extending them over about three orders of magnitude in wavelength. We exploit our smooth particle hydrodynamical simulations with chemo-photometric implementation anchored, a posteriori, to the global multiwavelength properties of our targets, to give insight into their evolution. Then we compare their evolutionary properties with those previously derived for several galaxies in groups. The evolution of our targets is driven by a merger that occurred several gigayears ago, in the redshift range 0.5 ≤ z ≤ 4.5, not unlike what we have already found for galaxies in groups. The merger shapes the potential well where the gas is accreting, driving the star formation rate and the galaxy evolution. Isolated galaxies should not have suffered from interactions for at least 3 Gyr. However, the initial merger is still leaving its signature on the properties of our targets. Several rejuvenation episodes, triggered by in situ accretion, are highlighted. Moreover, jellyfish morphologies appear as these galaxies achieve their maximum star formation rate, before their quenching phase.

Individual chemical abundances for 14 elements (C, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, and Ni) are derived for a sample of M dwarfs using high-resolution, near-infrared H-band spectra from the Sloan Digital Sky Survey-IV/Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey. The quantitative analysis included synthetic spectra computed with 1D LTE plane-parallel MARCS models using the APOGEE Data Release 17 line list to determine chemical abundances. The sample consists of 11 M dwarfs in binary systems with warmer FGK dwarf primaries and 10 measured interferometric angular diameters. To minimize atomic diffusion effects, [X/Fe] ratios are used to compare M dwarfs in binary systems and literature results for their warmer primary stars, indicating good agreement (<0.08 dex) for all studied elements. The mean abundance difference in primaries minus this work’s M dwarfs is −0.05 ± 0.03 dex. It indicates that M dwarfs in binary systems are a reliable way to calibrate empirical relationships. A comparison with abundance, effective temperature, and surface gravity results from the APOGEE Stellar Parameter and Chemical Abundances Pipeline (ASPCAP) Data Release 16 finds a systematic offset of [M/H], T
eff, log g = +0.21 dex, −50 K, and 0.30 dex, respectively, although ASPCAP [X/Fe] ratios are generally consistent with this study. The metallicities of the M dwarfs cover the range of [Fe/H] = −0.9 to +0.4 and are used to investigate Galactic chemical evolution via trends of [X/Fe] as a function of [Fe/H]. The behavior of the various elemental abundances [X/Fe] versus [Fe/H] agrees well with the corresponding trends derived from warmer FGK dwarfs, demonstrating that the APOGEE spectra can be used to examine Galactic chemical evolution using large samples of selected M dwarfs.
Chemical Properties of the Local Disk and Halo. II. Abundances of 3745 M Dwarfs and Subdwarfs from Improved Model Fitting of Low-resolution Spectra
Authors: Hejazi Neda , Lépine Sébastien , Nordlander Thomas
Published: March 2022

We present a model-fit pipeline to determine the stellar parameters of M-type dwarfs, which is an improvement on our previous work described in Hejazi et al. We apply this pipeline to analyze the low-resolution (R ∼ 2000) spectra of 3745 M dwarfs/subdwarfs, collected at the MDM Observatory, Lick Observatory, Kitt Peak National Observatory, and Cerro Tololo Inter-American Observatory. We examine the variation of the inferred parameter values in the H-R diagram constructed from their Gaia Early Data Release 3 (EDR3) parallaxes and optical magnitudes. We also study the distribution of our stars in the abundance diagram of [α/Fe] versus [M/H] and inspect the variation of their metallicity class, effective temperature, and surface gravity, as well as their Galactic velocity components U, V, and W, in this diagram. In addition, the analyses of the stars’ projected motions in the two-dimensional UV, VW, and UW planes, the variation of their chemical parameters in these planes, and their distribution in the abundance−velocity diagrams are important parts of this study. The precision of our model-fit pipeline is confirmed by the clear stratification of effective temperature and chemical parameters in the H-R diagram; the similarity of the stars’ distribution in the [α/Fe] versus [M/H] diagram and in the metallicity−velocity planes to those from other studies; the revealing of substructure in the abundance−velocity diagrams; and chemical homogeneity between the components of a set of binary systems.

We present “Extending the Satellites Around Galactic Analogs Survey” (xSAGA), a method for identifying low-z galaxies on the basis of optical imaging and results on the spatial distributions of xSAGA satellites around host galaxies. Using spectroscopic redshift catalogs from the SAGA Survey as a training data set, we have optimized a convolutional neural network (CNN) to identify z < 0.03 galaxies from more-distant objects using image cutouts from the DESI Legacy Imaging Surveys. From the sample of >100,000 CNN-selected low-z galaxies, we identify >20,000 probable satellites located between 36–300 projected kpc from NASA-Sloan Atlas central galaxies in the stellar-mass range

. We characterize the incompleteness and contamination for CNN-selected samples and apply corrections in order to estimate the true number of satellites as a function of projected radial distance from their hosts. Satellite richness depends strongly on host stellar mass, such that more-massive host galaxies have more satellites, and on host morphology, such that elliptical hosts have more satellites than disky hosts with comparable stellar masses. We also find a strong inverse correlation between satellite richness and the magnitude gap between a host and its brightest satellite. The normalized satellite radial distribution between 36–300 kpc does not depend on host stellar mass, morphology, or magnitude gap. The satellite abundances and radial distributions we measure are in reasonable agreement with predictions from hydrodynamic simulations. Our results deliver unprecedented statistical power for studying satellite galaxy populations and highlight the promise of using machine-learning for extending galaxy samples of wide-area surveys.
Lithium and Beryllium in NGC 752—an Open Cluster Twice the Age of the Hyades
Authors: Boesgaard Ann Merchant , Lum Michael G. , Chontos Ashley , Deliyannis Constantine P.
Published: March 2022

The surface abundances of the light elements lithium (Li) and beryllium (Be) reveal information about the physical processes taking place in stellar interiors. The investigation of the amount of these two elements in stars in open clusters shows the effect of age on those mechanisms. We have obtained spectra of both Li and Be in main-sequence stars in NGC 752 at high spectral resolution and high signal-to-noise ratios with HIRES on the Keck I telescope. In order to make meaningful comparisons with other clusters, we have determined the stellar parameters on a common scale. We have found abundances of Li and Be by spectral synthesis techniques. NGC 752 is twice the age of the well-studied Hyades. We find that (1) the Li dip centered near 6500 K is wider in NGC 752, having expanded toward cooler temperatures; (2) the Be dip is deeper in the older NGC 752; (3) the Li “peak” near 6200 K is lower by about 0.3 dex; (4) although there is little Be depletion in the cooler stars, it is possible that Be may be lower in NGC 752 than in the Hyades; and (5) the Li content in both clusters declines with decreasing temperature, but there is less Li in NGC 752 at a given temperature by ∼0.4 dex. These differences are consistent with the transport of the light-element nuclei below the surface convection zone as predicted by theory. That connection to rotational spin-down is indicated by the pattern of rotation with temperature in the two clusters.
Gamma-Ray Spectral Properties of the Galactic Globular Clusters: Constraint on the Number of Millisecond Pulsars
Authors: Wu Wei , Wang Zhongxiang , Xing Yi , Zhang Pengfei
Published: March 2022

We study the γ-ray spectra of 30 globular clusters (GCs) thus far detected with the Fermi Gamma-ray Space Telescope. Presuming that γ-ray emission of a GC comes from millisecond pulsars (MSPs) contained within the GC, a model that generates spectra for the GCs is built based on the γ-ray properties of the detected MSP sample. We fit the GCs’ spectra with the model, and for 27 of them, their emission can be explained as arising from MSPs. The spectra of the other three, NGC 7078, 2MS-GC01, and Terzan 1, cannot be fit with our model, indicating that MSPs’ emission should not be the dominant one in the first two and the third one has a unique hard spectrum. We also investigate six nearby GCs that have relatively high encounter rates compared to the comparison cases. The candidate spectrum of NGC 6656 can be fit with that of one MSP, supporting its possible association with the γ-ray source at its position. The five others do not have detectable γ-ray emission. Their spectral upper limits set limits of ≤1 MSPs in them, consistent with the numbers of radio MSPs found in them. The estimated numbers of MSPs in the γ-ray GCs generally match well those reported for radio pulsars. Our studies of the γ-ray GCs and the comparison nearby GCs indicate that the encounter rate should not be the only factor determining the number of γ-ray MSPs a GC contains.
DI Herculis Revisited: Starspots, Gravity Darkening, and 3D Obliquities
Authors: Liang Yan , Winn Joshua N. , Albrecht Simon H.
Published: March 2022

DI Herculis is an eclipsing binary famous for a longstanding disagreement between theory and observation of the apsidal precession rate, which was resolved when both stars were found to be severely misaligned with the orbit. We used data from the Transiting Exoplanet Survey Satellite (TESS) to refine our knowledge of the stellar obliquities and sharpen the comparison between the observed and theoretical precession rates. The TESS data show variations with a 1.07 day period, which we interpret as rotational modulation from starspots on the primary star. This interpretation is supported by the detection of photometric anomalies during primary eclipses consistent with starspot crossings. The secondary eclipse light curve shows a repeatable asymmetry that we interpret as an effect of gravity darkening. By combining the TESS data with previously obtained data, we determined the three-dimensional spin directions of both stars. Using this information, the updated value of the theoretical apsidal precession rate (including the effects of tides, rotation, and general relativity) is

A Red-noise Eigenbasis for the Reconstruction of Blobby Images
Authors: Hallur Pravita , Medeiros Lia , Lauer Tod R.
Published: March 2022

We demonstrate the use of an eigenbasis that is derived from principal component analysis (PCA) applied on an ensemble of random-noise images that have a “red” power spectrum; i.e., a spectrum that decreases smoothly from large to small spatial scales. The pattern of the resulting eigenbasis allows for the reconstruction of images with a broad range of image morphologies. In particular, we show that this general eigenbasis can be used to efficiently reconstruct images that resemble possible astronomical sources for interferometric observations, even though the images in the original ensemble used to generate the PCA basis are significantly different from the astronomical images. We further show that the efficiency and fidelity of the image reconstructions depends only weakly on the particular parameters of the red-noise power spectrum used to generate the ensemble of images.

Large-scale astronomical surveys have the potential to capture data on large numbers of strongly gravitationally lensed supernovae (LSNe). To facilitate timely analysis and spectroscopic follow-up before the supernova fades, an LSN needs to be identified soon after it begins. To quickly identify LSNe in optical survey data sets, we designed ZipperNet, a multibranch deep neural network that combines convolutional layers (traditionally used for images) with long short-term memory layers (traditionally used for time series). We tested ZipperNet on the task of classifying objects from four categories—no lens, galaxy-galaxy lens, lensed Type-Ia supernova, lensed core-collapse supernova—within high-fidelity simulations of three cosmic survey data sets: the Dark Energy Survey, Rubin Observatory’s Legacy Survey of Space and Time (LSST), and a Dark Energy Spectroscopic Instrument (DESI) imaging survey. Among our results, we find that for the LSST-like data set, ZipperNet classifies LSNe with a receiver operating characteristic area under the curve of 0.97, predicts the spectroscopic type of the lensed supernovae with 79% accuracy, and demonstrates similarly high performance for LSNe 1–2 epochs after first detection. We anticipate that a model like ZipperNet, which simultaneously incorporates spatial and temporal information, can play a significant role in the rapid identification of lensed transient systems in cosmic survey experiments.
The FloRes Database: A floral resources trait database for pollinator habitat-assessment generated by a multistep workflow
Authors: Baden-Böhm Franziska , App Mario , Thiele Jan
Published: March 2022

The decline of pollinating insects in agricultural landscapes proceeds due to intensive land use and the associated loss of habitat and food sources. Those insects depend on the spatial and temporal distribution of nectar and pollen as food resource. Hence, for nature conservation the spatio-temporal assessment of food quantity of habitats is necessary. Therefore, sufficient data of floral plant traits are required.

We present a raw database with the plant traits 1. flowering period, 2. floral-unit density, 3. nectar (nectar volume or sugar content of floral unit), 4. sugar concentration in nectar, 5. pollen mass or volume per floral unit, 6. protein content of pollen and 7. corolla depth. All traits are sampled from literature and online databases. The raw database consists of 843 unspecified (sp.) and specified plant species belong to 488 genera and 102 families with missing information. For utilizing the raw data, we developed a stepwise workflow unifying traits to comparable entities with identical units and aggregating them to an application database, called the FloRes Database (Floral Resources Database). FloRes contains the complete information of traits for 38 taxa and, when corolla depth is excluded, for 70 taxa. The stepwise workflow is implemented in five consecutive scripts written in R, that allow other users easily add information to the raw data and to compute their own application data set. FloRes can be used to evaluate food-resource supply of habitats for pollinators, e.g., to compare seed mixtures of agri-environmental measure, such as flower strips, taking into account flower phenology on a daily basis. Further, calculated for-resource supply can be used as input for simulation models of pollinator populations, such as the agent-based models BumbleBEEHAVE and SyrFitSources.

L’art à l’ère de la globalisation
Authors: Belting Hans
Published: March 2022

Ce texte est extrait d’un ouvrage coédité par l’historien allemand Hans Belting, consacré à la nouvelle géographie de l’art contemporain dans un contexte globalisé. L’auteur dresse un panorama de l’évolution de l’art et de l’histoire de l’art depuis 1989, année marquée par de grands événements historiques et par les premières expositions globales et inclusives. Belting analyse le passage de l’art « mondial » (dans lequel l’Autre est exclu de l’art occidental et du modernisme) à l’art « global » (postcolonial, polyphonique et multiculturel). En mettant en cause les notions de centre et de périphérie, il met en lumière comment cette évolution, tout comme l’impact des changements géopolitiques, ont eu des conséquences sur l’écriture de l’histoire de l’art.
L’art à l’ère de la globalisation
Authors: Soh Bejeng Ndikung Bonaventure
Published: March 2022

Le commissaire d’exposition d’origine camerounaise et directeur de la Haus der Kulturen der Welt [Maison des cultures du monde] de Berlin, Bonaventure Soh Bejeng Ndikung, examine dans ce texte l’évolution des musées à l’aune du phénomène de la globalisation. Si celui-ci a d’abord généré une tentative de diversification des institutions muséales (à partir des perspectives du genre, de l’origine ethnique, sociale ou géographique), elle est restée symbolique et sans conséquence majeure. C’est pourquoi l’auteur propose une méthode « décanonisante » qui consiste à élargir les canons esthétiques, supposés universels, en rassemblant au sein du musée des communautés et des géographies plurielles. La première étape de cette entreprise sera de démanteler les structures hiérarchiques qui produisent ces canons.
L’art à l’ère de la globalisation
Authors: Weibel Peter
Published: March 2022

Ce texte de l’historien de l’art autrichien d’origine hongroise Peter Weibel propose des pistes de réflexion sur les conséquences de la globalisation dans le champ de l’art contemporain. En pensant en termes d’intégration et d’assimilation, deux caractéristiques du système social à l’origine de la modernité, Weibel montre comment le mécanisme d’inclusion et d’exclusion se poursuit au cœur de la globalisation, qui apparaît dès lors comme le produit de la modernité occidentale. Il fait également le constat d’un double tournant : celui initié par la photographie, le film et la vidéo dans le phénomène de globalisation, et le « tournant performatif », avec la participation du public à l’œuvre d’art.
L’art à l’ère de la globalisation
Authors: Enwezor Okwui
Published: March 2022

Issu du texte inaugural de la documenta 11 (2002), cet essai marque un tournant dans la conception de l’art global. Le commissaire d’exposition d’origine nigériane Okwui Enwezor souligne le rôle du postcolonialisme dans l’émergence de la globalisation – qu’il définit en termes spatio-temporels. Par la transformation de « l’autre » en quelqu’un de visible et présent partout et tout le temps, le postcolonialisme permet, en effet, un dépassement des frontières du monde colonial. Dans le premier chapitre, Enwezor montre comment la globalisation et les nouvelles écritures postcoloniales de l’histoire remettent en cause la notion d’avant-garde. Dans le second chapitre, il met en évidence la façon dont les années 2000, signent, d’un point de vue éthique et politique, l’avènement d’un nouvel ordre de société globale, dans lequel, au-delà du colonialisme, la marge émerge violemment au centre, à l’image de Ground Zero.
L’art à l’ère de la globalisation
Authors: Brown Rebecca M.
Published: March 2022

Ce texte est une réponse à l’essai de Partha Mitter, qui défendait au milieu des années 2000 une histoire de l’art plus inclusive et proposait d’élargir la définition du modernisme communément admise. L’historienne de l’art Rebecca M. Brown conteste cette perspective et montre que l’intégration de régions périphériques dans les conceptions modernistes relègue les artistes non occidentaux à des modernités distantes ou dérivées. L’auteure plaide pour une réévaluation radicale de l’art moderne et propose un démantèlement de ses fondements spatio-temporels. Elle reprend ainsi à son compte la question de la provincialisation de l’Europe posée par Dipesh Chakrabarty dans Provincialiser l’Europe. La pensée postcoloniale et la différence historique (2000).

Par le biais du renvoi préjudiciel, la Cour de justice devient un juge de l’asile en interprétant les textes européens relatifs au droit d’asile. Que ce soit en matière d’octroi du statut de réfugié, de protection contre les traitements inhumains et dégradants ou de protection juridictionnelle effective, la jurisprudence de la Cour de justice oscille entre des interprétations favorables aux demandeurs d’asile et d’autres allant dans le sens des politiques restrictives des États membres.
