ATIVISMO JUDICIAL E PANPRINCIPIOLOGISMO
Authors: De Souza Luciane Leão 
Published: August 2023

O presente estudo visa discutir o ativismo judicial na forma do panprincipiologismo, uma variação do ativismo judicial, porém direcionado à criação de princípios. Para tanto, explica os princípios jurídicos, sua importância e contexto em que são criados; analisa o ativismo judicial e seu impacto em manifestações construtivas ou criativas; e esclarece sobre o panprincipiologismo como forma de ativismo judicial. A metodologia empregada no desenvolvimento deste artigo foi a pesquisa bibliográfica e documental, subsidiada no método dialético-argumentativo, permitindo concluir que apesar das constantes ofensas que os tribunais têm sofrido, especialmente o Supremo Tribunal Federal - STF, e mesmo reconhecendo-se que o que convencionou-se chamar de panprincipiologismo já trouxe resultados nocivos à democracia brasileira, não se pode negar que o Judiciário é decisivo na preservação da democracia contra o autoritarismo furtivo ou dissimulado. É importante conhecer as mudanças sociais, econômicas, políticas e culturais que podem influenciar os tribunais na tomada de decisões que visam regenerar a representatividade do regime democrático e, consequentemente, superar o desarranjo institucional. No entanto, não se pode aplaudir ou entender o panprincipiologismo como algo danoso à democracia. O ativismo às vezes é necessário e positivo e por esta razão, para afirmar se uma decisão judicial foi arbitrária ou não, é importante que se leve em conta o caso concreto.

Abstract
Precise estimates of protostellar masses are crucial to characterize the formation of stars of low masses down to brown dwarfs (BDs; M
* < 0.08 M
☉). The most accurate estimation of protostellar mass uses the Keplerian rotation in the circumstellar disk around the protostar. To apply the Keplerian rotation method to a protostar at the low-mass end, we have observed the Class 0 protostar IRAS 16253-2429 using the Atacama Large Millimeter/submillimeter Array (ALMA) in the 1.3 mm continuum at an angular resolution of 0.″07 (10 au), and in the 12CO, C18O, 13CO (J = 2–1), and SO (J

N
= 65−54) molecular lines, as part of the ALMA Large Program Early Planet Formation in Embedded Disks project. The continuum emission traces a nonaxisymmetric, disk-like structure perpendicular to the associated 12CO outflow. The position–velocity (PV) diagrams in the C18O and 13CO lines can be interpreted as infalling and rotating motions. In contrast, the PV diagram along the major axis of the disk-like structure in the 12CO line allows us to identify Keplerian rotation. The central stellar mass and the disk radius are estimated to be ∼0.12–0.17 M
☉ and ∼13–19 au, respectively. The SO line suggests the existence of an accretion shock at a ring (r ∼ 28 au) surrounding the disk and a streamer from the eastern side of the envelope. IRAS 16253-2429 is not a proto-BD but has a central stellar mass close to the BD mass regime, and our results provide a typical picture of such very-low-mass protostars.
Submillimeter Observations of Magnetic Fields in Massive Star-forming Region W75N

Abstract
This paper presents the results of full polarization observations of the massive star-forming region W75N, conducted with ∼3″ spatial resolutions at 345 GHz using the Submillimeter Array. The magnetic field structures in the dense cores of the region are derived using the linearly polarized continuum emission. The overall magnetic field strength and orientation are found to agree with those from the previous observations. The plane-of-sky component of the magnetic field in the region was calculated to be ∼0.8 ± 0.1 mG using the angular dispersion function method. Further analyses involving the polarization-intensity gradient-local gravity method and H13CO+ (4–3) line data indicated that the cloud is undergoing global gravitational collapse and the magnetic field is shaped by gravity and outflows in the dense core regions.
Swift Follow-up of Reported Radio Pulsars at Fermi 4FGL Unassociated Sources
Authors: Kerby Stephen , Falcone Abraham D. , Ray Paul S. 
Published: August 2023

Abstract
Following the discovery of radio pulsars at the position of Fermi-LAT unassociated sources by the TRAPUM group, we conduct Swift-XRT observations of six of those 4FGL sources to determine if any pulsar-like X-ray sources are present and to confirm the reported detection of an X-ray counterpart via eROSITA at 4FGL J1803.1−6708. At two of the six targets, we detect no X-ray sources at the TRAPUM radio position, placing an upper limit on the 0.3–10.0 keV flux. At 4FGL J1803.1−6708 we find an X-ray source at the TRAPUM and eROSITA position. At 4FGL J1858.3−5424 we find a new X-ray counterpart at the TRAPUM position with signal-to-noise ratio S/N = 4.17, but also detect a distinct and separate X-ray source. At 4FGL J1823.8−3544 and 4FGL J1906.4−1757 we detect no X-ray flux at the TRAPUM positions, but we do detect separate X-ray sources elsewhere in the Fermi error ellipse. At these last two targets, our newly detected Swift sources are possible alternatives to the radio pulsar associations proposed by TRAPUM. Our findings confirm several of the discoveries reported by the TRAPUM group but suggest that further observations and investigations are necessary to confirm the low-energy counterpart of several unassociated sources.
Unpacking Merger Jets: A Bayesian Analysis of GW170817, GW190425 and Electromagnetic Observations of Short Gamma-Ray Bursts

Abstract
We present a novel fully Bayesian analysis to constrain short gamma-ray burst (sGRB) jet structures associated with cocoon, wide-angle, and simple top-hat jet models, as well as the binary neutron star (BNS) merger rate. These constraints are made given the distance and inclination information from GW170817, observed flux of GRB 170817A, observed rate of sGRBs detected by Swift, and the neutron star merger rate inferred from LIGO’s first and second observing runs. A separate analysis is conducted where a fitted sGRB luminosity function is included to provide further constraints. The jet structure models are further constrained using the observation of GW190425, and we find that the assumption that it produced a GRB 170817–like sGRB which went undetected due to the jet geometry is consistent with previous observations. We find and quantify evidence for low-luminosity and wide-angle jet structuring in the sGRB population, independently from afterglow observations, with log Bayes factors of 0.45–0.55 for such models when compared to a classical top-hat jet. Slight evidence is found for a Gaussian jet structure model over all others when the fitted luminosity function is provided, producing log Bayes factors of 0.25–0.9 ± 0.05 when compared to the other models. However, without considering GW190425 or the fitted luminosity function, the evidence favors a cocoon-like model with log Bayes factors of 0.14 ± 0.05 over the Gaussian jet structure. We provide new constraints to the BNS merger rates of 1–1300 Gpc−3 yr−1 or 2–680 Gpc−3 yr−1 when a fitted luminosity function is assumed.

Abstract
We present early-phase panchromatic photometric and spectroscopic coverage spanning the far-ultraviolet to near-infrared regime of the nearest hydrogen-rich core-collapse supernova (SN) in the last 25 yr, SN 2023ixf. We observe early “flash” features in the optical spectra due to confined dense circumstellar material (CSM). We observe high-ionization absorption lines (Fe ii, Mg ii) in the ultraviolet spectra from very early on. We also observe a multipeaked emission profile of Hα in the spectrum beginning at ∼16 days, which indicates ongoing interaction of the SN ejecta with a preexisting shell-shaped CSM having an inner radius of ∼75 au and an outer radius of ∼140 au. The shell-shaped CSM is likely a result of enhanced mass loss ∼35–65 yr before the explosion assuming a standard red supergiant wind. The UV spectra are dominated by multiple highly ionized narrow absorption and broad emission features from elements such as C, N, O, Si, Fe, and Ni. Based on early light-curve models of Type II SNe, we infer that the nearby dense CSM confined to 7 ± 3 × 1014 cm (∼45 au) is a result of enhanced mass loss (10−3.0±0.5
M
⊙ yr−1) two decades before the explosion.
Equatorial Waves and Superrotation in the Stratosphere of a Titan General Circulation Model
Authors: Lewis Neil T. , Lombardo Nicholas A. , Read Peter L. , Lora Juan M. 
Published: August 2023

Abstract
We investigate the characteristics of equatorial waves associated with the maintenance of superrotation in the stratosphere of a Titan general circulation model. A variety of equatorial waves are present in the model atmosphere, including equatorial Kelvin waves, equatorial Rossby waves, and mixed Rossby–gravity waves. In the upper stratosphere, acceleration of superrotation is strongest around solstice and is due to interaction between equatorial Kelvin waves and Rossby-type waves in winter hemisphere midlatitudes. The existence of this “Rossby–Kelvin”-type wave appears to depend on strong meridional shear of the background zonal wind that occurs in the upper stratosphere at times away from the equinoxes. In the lower stratosphere, acceleration of superrotation occurs throughout the year and is partially induced by equatorial Rossby waves, which we speculate are generated by quasigeostrophic barotropic instability. Acceleration of superrotation is generally due to waves with phase speeds close to the zonal velocity of the mean flow. Consequently, they have short vertical wavelengths that are close to the model’s vertical grid scale and therefore likely to be not properly represented. We suggest that this may be a common issue among Titan general circulation models that should be addressed by future model development.
Image de la réglementation de la vitesse et position sociale dans le système de circulation routière

Between 1970 and 1973, road safety in France took on a new political and social importance with the creation of Inter-ministerial Organisms (an interdepartmental government body consisting of a commission and a special safety delegation) and the adoption of three broad measures: setting of a maximum legal blood alcohol content, compulsory wearing of seat belts, speed limit throughout the road network. This last measure is perhaps a kind of borderline case which bears directly on one of the most basic characteristics of the automobile - that is, its "performance" - and will in all probability give rise to very important changes in the use and image of the private automobile. The different aspects of this problem are dealt with in this article, first from the point of view of the methods used, then with respect to the role of social attitudes and hierarchy in road traffic. This last aspect is concerned with social attitudes to speed regulation, the causes of road accidents, road hazards and lack of safety - in other words, the consensus of opinion on automobile use.
Au cours des années 1970-1973, la sécurité routière en France prend une dimension politique et sociale de premier plan avec la création d'organismes Interministériels (Mission puis Délégation à la sécurité routière) et l'adoption de 3 grandes mesures : taux légal d'alcoolémie, port obligatoire de la ceinture de sécurité, limitation de vitesse sur tout le réseau routier. Cette dernière mesure apparaît comme une sorte de cas limite ayant une incidence directe sur l'une des caractéristiques fondamentales de l'automobile, ses "performances", et devrait logiquement entraîner des modifications profondes de l'usage et de l'image de l'automobile individuelle. Les différents aspects de ce problème sont abordés dans cet article au niveau des principes méthodologiques puis sur celui des représentations sociales et positions dans le système de la circulation routière. Ce dernier aspect implique les problèmes de l'attitude à l'égard de la réglementation de la vitesse, l'image des causes de l'accident de la route, le risque et l'insécurité, enfin le consensus quant à l'usage de d'automobile.
Ramassage ouvrier et structuration de l'espace
Authors: Gerardin B. 
Published: August 2023

The analyses of the systems organized for the transportation of the workers remain an area little studied in transportation economics. Recent researches undertaken at the initiative of the Institute for Transportation Research (IRT), Institute of Economic Studies (IEE) and the ATP socio-economy of Transports, have led to a better understanding of their importance both as transportation system and as elements of the personnel policy of the enterprise.The repercussions of these transportation systems on the structure of space and on the evolution of daily commuting have not been studied in-depth. This article, after having presented the results of several researches already completed tries to integrate the phenomenon of worker transportation with economic theories of space and migration. The confrontation of neo-classical models analyzing migration as a process of adjustment between regions of high and low salaries with the empirical results of the investigations of the transportation workers networks shows clearly the inadequation of these models. The behaviour of the workers concerned is influenced not only by the sphere of production, but also by family and socio-cultural factors. A vast field of research remains open.
Les services de transport-employeur restent un domaine mal connu de l'économie des transports. Quelques recherches récentes, menées a l'initiative de l'Institut de Recherche des Transports (IRT), de l'Institut des Etudes Economiques (IEE) et de l'ATP socio-économie des Transports ont permis de mieux mesurer l'importance, aussi bien en tant que système de transport, qu'en tant qu'élément de la politique du personnel de l'entreprise.Les répercussions de ces systèmes de transport sur la structuration de l'espace et l'évolution des phénomènes migratoires n'ont pas encore fait l'objet de travaux approfondis. Cet article, après avoir fait le point sur quelques-unes des recherches déjà réalisées, tente dans une deuxième partie, de lier le phénomène ramassage aux théories économiques de l'espace et des migrations. La confrontation des modèles théoriques néoclassiques analysant la migration comme un processus d'ajustement entre zones de bas et de hauts salaires, avec les résultats des enquêtes sur les systèmes de transport-employeur, met clairement en évidence l'inadéquation de ces modèles. Le salarié ramassé n'est pas totalement lié à la sphère de la production, mais réagit aussi en fonction de déterminants familiaux et de son environnement socio-culturel. Un vaste champ de recherche reste ouvert.
La desserte de la périphérie urbaine : recherche d'une intégration des transports collectifs et semi-collectifs

The set-up of most various solutions to palliate the need for mass transportation in suburbs proves the existence of a still widerly unexploited "transportation field".First, the nickness of all these means of transportation, Rall-way between private and public transportation, is shown through a classification of paratransit. The potential adaptation of paratransit to the various needs of urban transportation is based upon this large technical, as well as economical, diversity of this unexploited transportation field.Then, it is shown how a complete integration of mass transportation and paratransit, within the frame of a global development policy of the suburbs, can fulfill the need for transportation in these areas.
La mise en place de solutions très diverses pour pallier l'insuffisance de l'offre de transports collectifs en périphérie urbaine prouve l'existence d'un "champ transport" encore largement inexploité.La première partie s'efforce de montrer à travers une typologie des transports semi-collectifs, toute la richesse de cet ensemble de modalités intermédiaires entre le transport individuel et les transports collectifs. C'est sur cette grande diversité tant technique qu'économique, que repose l'adaptation potentielle des transports semi-collectifs aux multiples expressions des besoins de déplacement urbain.Dans la seconde partie, nous montrons alors comment une intégration totale des transports collectifs et semi-collectifs permet de répondre à la desserte des zones urbaines périphériques, dans le cadre d'une politique globale d'aménagement de ces zones.
The French goods-traffic data under-estimate the activity of transport
Authors: Cornuel Didier 
Published: August 2023

The goods-traffic data collected by the Ministry of Transport about road, railway, in-land, waterways and pipe-lines give the metric tons and tonne-kilometers of transported goods within the national borders. These statistics under-estimate the transport activity because (i) they don't take into account the domestic coasting-trade and the international road-transports carried out by foreign transporters, (ii) they don't include in their definition the foreign part of international transport distances. By estimating all these traffics, the 1976 transport activity is increased by 13 per cent. Traffic explanation models must be qualified too. At last, (iii) the appraisal of the value of the traffic could give a better understanding to the goods-transport phenomena.
Les données de trafic, réunies par le Ministère des Transports pour la route, le chemin de fer, la voie d'eau et les oléoducs donnent les tonnages et les tonnages-kilométriques des marchandises transportées à l'intérieur des frontières nationales. Cette statistique sous-estime l’activité du transport à cause (i) des insuffisances de mesure comme l'absence de mesure du cabotage et des transports routiers effectués par des étrangers (ii) des insuffisances de la définition, qui ne prend pas en compte la partie étrangère des transports internationaux. En estimant tous ces trafics, on majore de 13 % le trafic de 1976, ce qui n'est pas sans influence sur les modèles d'explications du trafic. Enfin (iii) la mesure du trafic en valeur permettrait de mieux comprendre les phénomènes du transport de marchandises.
