REFLEKSI KRITIS TERHADAP KONSEP RESTORATIVE JUSTICE DALAM PERLINDUNGAN DAN PENGELOLAAN LINGKUNGAN HIDUP DI INDONESIA
Authors: Pardede Josua Navirio , Santoso Wahyu Yun 
Published: September 2022

Abstrak
Restorative Justice/keadilan restoratif merupakan konsep yang menempatkan upaya pemulihan korban sebagai fokus utama penegakan hukum. Sebagai metamorfosis atas keadilan retributif, restorative justice mempertanyakan bagaimana korban kejahatan didudukkan, dan fokus hasil akhir yang hendak dicapai. Keadilan retributif lebih berfokus pada hukuman yang ideal bagi pelaku, sementara keadilan restoratif berfokus pada keadilan substantif bagi korban melalui upaya-upaya pemulihan hak dan penderitaan yang dialami korban.
Keadilan restoratif memiliki peluang penerapan dalam konteks hukum lingkungan, baik pada penyelesaian sengketa lingkungan; pemulihan dampak lingkungan; hingga pertanggungjawaban pidana dalam pencemaran dan/atau kerusakan lingkungan hidup, sehingga hal ini menjadi menarik untuk diberikan kritik dengan mendasarkan sekurangnya pada dua aspek: eksklusivitas konsep dengan fokus utama penerapan keadilan restoratif pada manusia atas dasar gagasan kemanusiaan; dan kompleksitas isu lingkungan untuk bisa dimoderasi pemulihannya melalui konsep keadilan restorative.
Penelusuran dalam artikel ini menemukan bahwa meskipun secara normatif konsep restorative justice belum tertulis secara eksplisit di dalam UU PPLH, namun konsep perlindungan dan pengelolaan lingkungan hidup telah mengadopsi ide besar dari “keadilan restoratif” ini dalam rangka pemulihan dan perlindungan bagi lingkungan

Abstract
We present the direct imaging discovery of a low-mass companion to the nearby accelerating F star, HIP 5319, using SCExAO coupled with the CHARIS, VAMPIRES, and MEC instruments in addition to Keck/NIRC2 imaging. CHARIS JHK (1.1–2.4 μm) spectroscopic data combined with VAMPIRES 750 nm, MEC Y, and NIRC2 L
p photometry is best matched by an M3–M7 object with an effective temperature of T = 3200 K and surface gravity log(g) = 5.5. Using the relative astrometry for HIP 5319 B from CHARIS and NIRC2, and absolute astrometry for the primary from Gaia and Hipparcos, and adopting a log-normal prior assumption for the companion mass, we measure a dynamical mass for HIP 5319 B of

This work underscores the importance of assumed priors in dynamical models for companions detected with imaging and astrometry, and the need to have an updated inventory of system measurements.
Coaxing the Eclipsing Binary V367 Cygni out of Its Shell
Authors: Davidge T. J. 
Published: September 2022

Abstract
Spectra that cover 0.63–0.69 μm with a spectral resolution ∼17,000 are presented of the W Serpentis system V367 Cygni. Absorption lines of Fe ii and Si ii that form in a circumsystem shell are prominent features, and the depths of these are stable with time, suggesting that the shell is smoothly distributed and well mixed. Further evidence of uniformity comes from modest radial velocity variations measured in the deepest parts of the shell lines. It is suggested that motions previously attributed to rotation of the shell are instead artifacts of contamination from the donor star spectrum. A donor star spectrum is extracted that is consistent with that of an early to mid-A giant. The depths of metallic lines in the donor spectrum vary with orbital phase, suggesting that spot activity covers a large fraction of the surface of that star. A spectrum of the accretion disk that surrounds the second star is also extracted, and similarities are noted with the emission spectra of Herbig Ae/Be stars. In addition to variations with orbital phase, Hα changes with time over timescales of no more than two orbits. A tentative detection of He i 6678 emission is made near primary minimum, but not at other phases. Finally, projected emission from hot dust in and around V367 Cyg is more or less symmetric and extends over 28″, or 0.09 pc at the distance of the system; V367 Cyg is thus expelling matter into a large volume of the surrounding space.
Exploring the Fate of Stellar Core Collapse with Supernova Relic Neutrinos
Authors: Ashida Yosuke , Nakazato Ken’ichiro 
Published: September 2022

Abstract
Core collapse of massive stars leads to different fates for various physical factors, which gives different spectra of the emitted neutrinos. We focus on the supernova relic neutrinos (SRNs) as a probe to investigate the stellar collapse fate. We present the SRN fluxes and event rate spectra at a detector for three resultant states after stellar core collapse, the typical mass neutron star, the higher mass neutron star, or the failed supernova forming a black hole, based on different nuclear equations of state. Then possible SRN fluxes are formed as mixtures of the three components. We also show the expected sensitivities at the next-generation water-based Cherenkov detectors, SK-Gd and Hyper-Kamiokande, as constraining the mixture fractions. This study provides a practical example of extracting astrophysical constraints through SRN measurement.
Accretion Burst Echoes as Probes of Protostellar Environments and Episodic Mass Assembly

Published: September 2022

Abstract
Protostars likely accrete material at a highly time-variable rate, but measurements of accretion variability from the youngest protostars are rare, as they are still deeply embedded within their envelopes. Submillimeter/millimeter observations can trace the thermal response of dust in the envelope to accretion luminosity changes, allowing variations in the accretion rate to be quantified. In this paper, we present contemporaneous submillimeter/millimeter light curves of variable protostars in Serpens Main, as observed by the ALMA Atacama Compact Array (ACA), the Submillimeter Array (SMA), and the James Clerk Maxwell Telescope (JCMT). The most recent outburst of EC 53 (V371 Ser), an ∼18 month periodic variable, is well sampled in the SMA and JCMT observations. The SMA light curve of EC 53 is observed to peak weeks earlier and exhibit a stronger amplitude than at the JCMT. Stochastic variations in the ACA observations are detected for SMM 10 IR, with an amplitude a factor of ∼2 greater than that seen by the JCMT. We develop a toy model of the envelope response to accretion outbursts to show that EC 53's light curves are plausibly explained by the delay associated with the light travel time across the envelope and the additional dilution of the JCMT response, due to the incorporation of cold envelope material in the beam. The larger JCMT beam can also wash out the response to rapid variations, which may be occurring for SMM 10 IR. Our work thus provides a valuable proof of concept for the use of submillimeter/millimeter observations as a means of probing both the underlying accretion luminosity variations and the protostellar environment.
Evidence for the Three Wave Interactions in the Vicinity of an Interplanetary Shock
Authors: Thejappa G. 
Published: September 2022

Abstract
We present the high time resolution in situ observations of coherent one-dimensional magnetic-field-aligned Langmuir wave packets with well-defined low frequency modulations (beats) in the upstream region of a coronal mass ejection driven supercritical quasi-perpendicular interplanetary (IP) shock. We show that these beat-type waveforms provide what is believed to be the first observational evidence for one of the most important three wave interactions, called the electrostatic decay instability (ESD)

(L is the pump Langmuir wave excited by the shock accelerated electron beam, and L′ and S are the daughter Langmuir and ion sound waves, respectively). We also show that (1) the spectra of these wave packets contain the signatures of L, L′, and S, which satisfy the resonance conditions required for excitation of ESD, (2) the peak intensities of these wave packets well exceed the ESD threshold values, and (3) the speed of the electron beam estimated using the resonance conditions is very close to the typical observed speeds of the IP shock accelerated electron beams. The implication of these findings is that (1) the shock accelerated electron beams probably are stabilized by the three wave interaction

FastQSL: A Fast Computation Method for Quasi-separatrix Layers
Authors: Zhang PeiJin , Chen Jun , Liu Rui , Wang ChuanBing 
Published: September 2022

Abstract
Magnetic reconnection preferentially takes place at the intersection of two separatrices or two quasi-separatrix layers, which can be quantified by the squashing factor Q, whose calculation is computationally expensive due to the need to trace as many field lines as possible. We developed a method (FastQSL) optimized for obtaining Q and the twist number in a 3D data cube. FastQSL utilizes the hardware acceleration of the graphics processing unit and adopts a step-size adaptive scheme for the most computationally intensive part: tracing magnetic field lines. As a result, it achieves a computational efficiency of 4.53 million Q values per second. FastQSL is open source, and user-friendly for data import, export, and visualization.
Filament Leg–Leg Reconnection as a Source of Prominent Supra-arcade Downflows
Authors: Dudík Jaroslav , Aulanier Guillaume , Kašparová Jana , Karlický Marian , Zemanová Alena , Lörinčík Juraj , Druckmüller Miloslav 
Published: September 2022

Abstract
We report on the interaction of the legs of the erupting filament of 2012 August 31 and associated prominent supra-arcade downflows (P-SADs) as observed by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory. We employ a number of image processing techniques to enhance weak interacting features. As the filament erupts, both legs stretch outwards. The positive-polarity leg also untwists and splits into two parts. The first part runs into the conjugate (negative-polarity) leg, tearing it apart. The second part then converges into the remnant of the conjugate leg, after which both weaken and finally disappear. All these episodes of interaction of oppositely oriented filament legs are followed by the appearance of P-SADs, seen in the on-disk projection to be shaped as loop tops, along with many weaker SADs. All SADs are preceded by hot supra-arcade downflowing loops. This observed evolution is consistent with the three-dimensional rr–rf (leg–leg) reconnection, where the erupting flux rope reconnects with itself. In our observations, as well as in some models, the reconnection in this geometry is found to be long lasting. It plays a substantial role in the evolution of the flux rope of the erupting filament and leads to prominent SADs.
Evolution of an Emerging Anti-Hale Region and its Associated Eruptive Solar Flares in NOAA AR 12882

Published: September 2022

Abstract
Solar active regions that violate the Hale–Nicholson rule are rare, but once formed, they tend to be flare-productive. In this letter, we investigated the evolution of an anti-Hale region newly emerging from the active region AR 12882 with a regular Hale distribution. The entire active region became very active, producing two eruptive flares within 48 hr after the emergence of the anti-Hale region. Strong photospheric shear motions appeared in this anti-Hale region, changing its tilt angle from the north–south direction to the east–west direction. The flux emergence and shearing motions continuously injected magnetic energy and negative magnetic helicity into the upper atmosphere. Meanwhile, the upper coronal structure changed from double J-shaped to reverse S-shaped, forming a magnetic flux rope lying above the anti-Hale region. This magnetic flux rope erupted successfully, then re-formed and erupted successfully again, producing a C2.7 flare and an M1.6 flare, respectively. Moreover, a large cusp structure was observed to form next to the flaring region after the M1.6 flare. Accordingly, we conclude that the evolution of the emerging anti-Hale region provides sufficient magnetic energy and helicity for the flares, and the interaction between the emerging anti-Hale region and the preexisting Hale active region eventually promotes the flares to be eruptive.
En oubliant, en écrivant. Vieillesse et amnésie créative dans les nouvelles d’Ulrike Draesner et d’Anna Katharina Hahn
Authors: Arlaud Sylvie 
Published: September 2022

Ulrike Draesner ( Ichs Heimweg macht alles allein et Josef rennt ) et Anna Katharina Hahn ( Kommune Kalk ) ont renouvelé le regard porté sur la « vieillesse » en travaillant la langue à hauteur de corps dans trois textes courts parus entre 2003 et 2011. Les trois textes à la première personne mettent au centre de leur dispositif des « vieux » et des « vieilles » en s’appuyant sur leur dégénérescence physique et mentale pour opérer un effacement productif qui est aussi un bain de jouvence littéraire. Le travail sur l’identité, inscrite dans la langue et sa grammaire, sa constitution par la société et sa déconstruction par la maladie, accompagne une écriture qui brosse à rebours les clichés, l’horizon d’attente du lecteur et la langue. Comment façonner le monde alors même qu’il s’efface ? Quelle est la place du lecteur dans cet effacement ? Chacun des récits, entre « tournant linguistique » et « tournant social », est un exemple abouti de la force d’un art qui permet de proposer un changement de perspective sur la vieillesse et la maladie en engageant pleinement le lecteur.
La science est-elle soluble dans des projets techno-industriels ? Querelles autour de la géothermie profonde à l’Eurométropole de Strasbourg (2012-2020)
Authors: Chavot Philippe , Masseran Anne , Serrano Yeny , Zoungrana Jean 
Published: September 2022

Cet article analyse les désaccords entre mondes industriel et scientifique dans le champ de la géothermie profonde alsacienne des années 2010. Cette querelle où se croisent interprétations scientifiques et intérêts industriels reflète les divergences de vues entre les mondes sociaux en présence sur la façon dont la science et les scientifiques doivent intervenir dans les projets de géothermie. La notion de paradigme de communication combinée à celle d’ethos discursif permet de saisir les dynamiques qui fondent les discours publics sur la géothermie : du côté des industriels une communication d’acceptabilité insiste sur la maturité du domaine et la maitrise des risques ; du côté des scientifiques, des approches plus pédagogiques pointent les lieux où des travaux sont nécessaires pour optimiser le développement de la géothermie profonde. Les désaccords apparaissent au grand jour suite aux séismes affectant l’Eurométropole de Strasbourg en 2019 et 2020.
La phase d’information dans l’obligation de rendre des comptes. Le rôle des conseils d’administration dans les agences de l’Union européenne
Authors: Font Nuria , Pérez-Durán Ixchel 
Published: September 2022

La création des agences de l’Union européenne a suscité des discussions normatives et théoriques sur leur imputabilité et leur légitimité démocratique. Cette étude examine dans quelle mesure différentes caractéristiques concernant le modèle institutionnel des agences les incitent à fournir des informations sur leurs performances. Pour ce faire, elle mesure quatre aspects pour lesquels leurs organes directeurs sont censés fournir des informations : les décisions de gouvernance, la performance des politiques, les questions financières et les interactions avec les parties prenantes. En utilisant un nouvel ensemble de données de déclarations informatives incluses dans 199 rapports d’activité annuels de 29 agences au cours de la période 2010-2016, cette étude démontre que l’imputabilité formelle influence positivement la fourniture d’informations sur les questions de gouvernance et de politiques, et que la création d’organes scientifiques au sein des agences améliore la fourniture d’informations sur les aspects liés à la gouvernance, la performance des politiques et leurs interactions avec les parties prenantes. Enfin, cet article constate que les agences qui pratiquent une réglementation plus directe sont soumises à de plus grandes exigences de transparence concernant leurs décisions de gouvernance et leurs interactions avec les parties prenantes. Remarques à l’intention des praticiens L’étude fournit aux praticiens un outil analytique pour évaluer la fourniture d’informations sur les décisions et les actions des conseils d’administration sur les questions de gouvernance, la performance des politiques, les aspects financiers et leurs interactions avec les parties prenantes.
Vieillir, trébucher, créer
Authors: Brody Baudin Marianne 
Published: September 2022

Les couches de temps s’ajoutent les unes aux autres, se superposent mais aussi se plissent, se fondent entre elles et créent l’épaisseur subjective. Une part de cette épaisseur nous reste inconnue, enfouie, refoulée, inconsciente, comme étrangère. La prise de conscience de la vieillesse, son identification selon les modes passif et actif, comprenant non seulement la finitude mais aussi toute cette épaisseur jamais pétrifiée de l’histoire d’un sujet, renforce l’intérêt pour la vie même et milite pour son accomplissement le plus abouti. Pour qu’elle ait lieu, l’inattendu est précieux : le modèle du trébuchement est proposé dans l’article comme forme de l’inattendu qu’il ait lieu au détour d’un chemin, au cours d’une analyse ou au hasard d’une rencontre, quand la sortie de l’habitude, voire la désorientation momentanée sont autant d’opportunités pour engager un ou des changements de point de vue. Loin de la redouter ou de la repousser et surtout de la dénier, reconnaitre la vieillesse, la sienne comme celle des autres, inscrit le sujet dans sa trajectoire personnelle, proche des autres, bien qu’unique. L’auteur illustre son propos par deux vignettes cliniques et une analyse du Bal de têtes, dernière partie de la Recherche du Temps Perdu où Proust, rencontrant la vieillesse, comprend sa vocation d’écrivain et l’importance de la création d’une œuvre.

Mangroves occur in tropical and subtropical regions, including harsh arid areas. Little is known about how the environmental conditions of deserts influence the ecology of mangrove seedlings. The seedlings of the mangrove Avicennia marina were examined in situ in a natural stand of the southern Red Sea coast of Saudi Arabia to (1) estimate and compare the growth rate of A. marina between selected microhabitats with different tidal exposures, and (2) examine the influence of sandstorms on the growth and survival of the seedlings. Samplings were conducted in four zones established according to their tidal exposure: low tidal exposure (Z1), medium tidal exposure (Z2), high tidal exposure with numerous burrows (Z3), and high tidal exposure with a few or no burrows (Z4). Vertical growth and mortality of the seedlings and selected environmental variables were quantified. The results show that seedling growth rates differed significantly between the sampling zones, the highest growth being found in the high tidal regions (Z3 followed by Z4) and the lowest growth in Z1. Growth rate followed a significant decreasing pattern over time, coinciding with increasing air temperature and decreasing relative humidity. Sandstorms showed a marked increase in July, leading to massive dust deposition that caused extensive mortality of the seedlings by burial. Our study highlights that seedling growth can be affected by the extent of tidal inundation and that sandstorms act as a natural stressor.
