Explicit Symplectic Methods in Black Hole Spacetimes
Authors: Wu Xin , Wang Ying , Sun Wei , Liu Fu-Yao , Han Wen-Biao
Published: December 2022

Many Hamiltonian problems in the solar system are separable into two analytically solvable parts, and thus serve as a great chance to develop and apply explicit symplectic integrators based on operator splitting and composing. However, such constructions are not in general available for curved spacetimes in general relativity and modified theories of gravity because these curved spacetimes correspond to nonseparable Hamiltonians without the two-part splits. Recently, several black hole spacetimes such as the Schwarzschild black hole were found to allow for the construction of explicit symplectic integrators, since their corresponding Hamiltonians are separable into more than two explicitly integrable pieces. Although some other curved spacetimes including the Kerr black hole do not have such multipart splits, their corresponding appropriate time-transformation Hamiltonians do. In fact, the key problem in obtaining symplectic analytically integrable decomposition algorithms is how to split these Hamiltonians or time-transformation Hamiltonians. Considering this idea, we develop explicit symplectic schemes in curved spacetimes. We introduce a class of spacetimes whose Hamiltonians are directly split into several explicitly integrable terms. For example, the Hamiltonian of a rotating black ring has a 13-part split. We also present two sets of spacetimes whose appropriate time-transformation Hamiltonians have the desirable splits. For instance, an eight-part split exists in a time-transformed Hamiltonian of a Kerr–Newman solution with a disformal parameter. In this way, the proposed symplectic splitting methods can be used widely for long-term integrations of orbits in most curved spacetimes we know of.

We report the discovery of one possible neutron star binary (P
orb = 0.8666 days) by using LAMOST low-resolution spectroscopic data. The visible companion is a late A-type dwarf (T
eff = 7900 ± 200 K; logg = 4.3 ± 0.2; M = 1.7 ± 0.1 M
⊙; R = 1.7 ± 0.2 R
⊙) at a distance of 1.11 ± 0.03 kpc. No double-lined feature can be seen from the Gran Telescopio Canarias/HORuS high-resolution spectra; thus the radial-velocity variation indicates an invisible object hiding in the binary. The system’s optical light curves show clear ellipsoidal variability, suggesting that the visible companion is tidal distorted. By fitting the multiband light curves with the eclipsing light-curve (ELC) code and the Wilson–Devinney (WD) code, we constrain the mass of the invisible star to be 1.1–1.3 M
⊙. Spectral disentangling shows no additional component with optical absorption spectra, supporting the idea that the system contains one compact object. No X-ray or UV emission is detected in the ROSAT archive observations. Therefore, we suspect the invisible object is more likely a neutron star rather than a white dwarf. Our finding suggests the ability of LAMOST spectroscopic survey to discover X-ray-quiescent compact objects.

We present results from an atmospheric retrieval analysis of Gl 229B using the Brewster retrieval code. We find the best fit model to be cloud-free, consistent with the T dwarf retrieval work of Line et al.; Zalesky et al. and Gonzales et al. Fundamental parameters (mass, radius, log(L

eff where our retrieved T
eff is approximately 100 K cooler than the evolutionary model-based SED value. We find a retrieved mass of

We report an overall subsolar metallicity due to atmospheric oxygen depletion, but find a solar [C/H], which matches that of the primary. We find that this work contributes to a growing trend in retrieval-based studies, particularly for brown dwarfs, toward supersolar C/O ratios and discuss the implications of this result on formation mechanisms and internal physical processes, as well as model biases.
Estimating the Convective Turnover Time

Published: December 2022

The introduction of the Rossby number (R0), which incorporates the convective turnover time (τ), in 1984 was a pioneering idea for understanding the correlation between stellar rotation and activity. The convective turnover time, which cannot be measured directly, is often inferred using existing τ–mass or τ–color relations, typically established based on an ensemble of different types of stars by assuming that τ is a function of mass. In this work, we use Gaia Early Data Release 3 to demonstrate that the masses used to establish one of the most cited τ-mass relations are overestimated for G-type dwarfs and significantly underestimated for late M dwarfs, offsets that affect studies using this τ–mass relation to draw conclusions. We discuss the challenges of creating such relations then and now. In the era of Gaia and other large data sets, stars used to establish these relations require characterization in a multidimensional space, rather than via the single-characteristic relations of the past. We propose that new multidimensional relations should be established based on updated theoretical models and all available stellar parameters for different interior structures from a set of carefully vetted single stars, so that the convective turnover time can be estimated more accurately.
Studying the Properties of Compressible Magnetohydrodynamic Turbulence Using Synchrotron Fluctuation Statistics
Authors: Wang Ru-Yue , Zhang Jian-Fu , Lazarian Alex , Xiao Hua-Ping , Xiang Fu-Yuan
Published: December 2022

We study the observable properties of compressible magnetohydrodynamic (MHD) turbulence covering different turbulence regimes, based on synthetic synchrotron observations arising from 3D MHD numerical simulations. Using the synchrotron emissivity and intensity, we first explore how the cosmic-ray spectral indices affect the measurements of the turbulence properties by employing normalized correlation functions. We then study how the anisotropy of the synchrotron total and polarization intensities arising from the three fundamental MHD modes varies with the viewing angle, i.e., the angle between the mean magnetic field and the line of sight. We employ the ratio of the quadrupole moment to the monopole moment (QM) for this purpose. Our numerical results demonstrate that: (1) the two-point correlation function of synchrotron statistics for the arbitrary cosmic-ray spectral index is related to the special case of the magnetic field index γ = 2, in agreement with the analytical formulae provided by Lazarian & Pogosyan; (2) the anisotropy of the synchrotron total and polarization intensities arising from the Alfvén and slow modes increases with the increase of the viewing angle, while that of fast mode remains almost unchanged with the viewing angle; and (3) the analytical formulae of the synchrotron intensities for studying turbulence can be applied to describe the statistics of the polarization intensities, and the QM can be successfully used to recover the turbulence anisotropy. This study validates the analytical approach of Lazarian & Pogosyan and opens up a way of studying turbulence from observations.
Effects of Background Periodic Flow on MHD Fast-wave Propagation to a Coronal Loop
Authors: Yu D. J.
Published: December 2022

This paper investigates the propagation of MHD fast waves into a cylindrical coronal loop through an inhomogeneous stationary flow region. The background flow is assumed to have a small, spatially periodic structure in addition to a constant speed. This study focuses on the absorption of the wave energy in Alfvén resonance, comparing it with the constant flow case. A new flow (absorption) regime is induced by the periodic flow structure, which enhances the absorption for the antiparallel flow and inverse absorption (overreflection) for the parallel flow with respect to the axial wavevector, depending on the transitional layer and flow profiles. A giant overreflection and anomalous absorption behavior arises for some flow configurations. In the other flow regimes, its effect on the absorption is shown to be weak.

Scattered-light imaging studies have detected nearly two dozen spiral arm systems in circumstellar disks, yet the formation mechanisms for most of them are still under debate. Although existing studies can use motion measurements to distinguish leading mechanisms such as planet–disk interaction and disk self-gravity, close-in stellar flybys can induce short-lived spirals and even excite arm-driving planets into highly eccentric orbits. With unprecedented stellar location and proper-motion measurements from Gaia Data Release 3 (DR3), here we study for known spiral arm systems their flyby history with their stellar neighbors by formulating an analytical on-sky flyby framework. For stellar neighbors currently located within 10 pc of the spiral hosts, we restrict the flyby time to within the past 104 yr and the flyby distance to within 10 times the disk extent in scattered light. Among a total of 12,570 neighbors that are identified in Gaia DR3 for 20 spiral systems, we do not identify credible flyby candidates for isolated systems. Our analysis suggests that a close-in recent flyby is not the dominant formation mechanism for isolated spiral systems in scattered light.
Stellar Loci. VI. An Updated Catalog of the Best and Brightest Metal-poor Stars

Published: December 2022

We employ Gaia, Two Micron All Sky Survey, and ALLWISE photometry, as well as astrometric data from Gaia, to search for relatively bright very metal-poor (VMP; [Fe/H] < −2.0) giant star candidates using three different criteria: (1) the derived Gaia photometric metallicities from Xu et al., (2) the lack of stellar molecular absorption near 4.6 μm, and (3) their high tangential velocities. With different combinations of these criteria, we have identified six samples of candidates with G < 15: the Gold sample (24,304 candidates), the Silver GW sample (40,157 candidates), the Silver GK sample (120,452 candidates), the Bronze G sample (291,690 candidates), the Bronze WK sample (68,526 candidates), and the Low-b sample (4645 candidates). The Low-b sample applies to sources with low Galactic latitude, ∣b∣ < 10°, while the others are for sources with ∣b∣ > 10°. By crossmatching with results derived from medium-resolution spectroscopy (R ∼ 1800) from LAMOST DR8, we establish that the success rate for identifying VMP stars is 60.1% for the Gold sample, 39.2% for the Silver GW sample, 41.3% for the Silver GK sample, 15.4% for the Bronze G sample, 31.7% for the Bronze WK sample, and 16.6% for the Low-b sample, respectively. An additional strict cut on the quality parameter RUWE < 1.1 can further increase the success rate of the Silver GW, Silver GK, and Bronze G samples to 46.9%, 51.6%, and 29.3%, respectively. Our samples provide valuable targets for high-resolution follow-up spectroscopic observations and are made publicly available.

Published: December 2022

BACKGROUND: The resolution of the problem of HIV and AIDS seems to be deadlocked both at the national and local government levels, actors related to the issue of HIV and AIDS prevention seem powerless to dispel the trend of increasing HIV and AIDS infections. The purpose of this research is to become a reference in various HIV and AIDS prevention efforts
METHOD: This type of research is qualitative research. The informants in this study were 25 people who were selected based on the criteria in accordance with the initial design of the study. These informants are key actors representing members of the City Health Office, Palu City Rutan Class II, Palu City AIDS Commission (KPA Palu City), Central Sulawesi Provincial AIDS Commission (KPA Prov. Central Sulawesi), Risk Groups (Housewives), Prisoners, Youth, Health Cadres). The sampling technique uses grounded research techniques that seek to explore in depth the phenomenon of the discourse on HIV and AIDS prevention.
RESULTS: The result of the research is that the construction of discourse on HIV and AIDS prevention operates in the form of production and organization of discourse controlled by the media through the dissemination of knowledge that has been legitimized by the power elite. Knowledge of HIV and AIDS originating from actors is produced and reproduced in the form of discourse by the media so that it is transformed into a dominant discourse. Conflictual discourses on HIV and AIDS tend to be parallel to the discourses held by actors because the configuration of conflict discourse is built on the basis of public morality.
CONCLUSION: The local government, especially the City of Palu, makes a basic scheme and roadmap in preventing HIV and AIDS transmission by building wider synergy and collaboration. Public health degree.

Background: During the current pandemic, it is necessary to continue to strengthen motivation and pride as a nurse as an effort to build nurses' commitment to realizing OCB. At this time the domestic nursing profession is required to be able to compete by improving the quality of nursing services. One of the bases for improving the quality of nursing services is that nurses must have a sense of pride as professional nurses with competencies that can answer internal and external challenges. Based on research on 105 Unusa lecturers in 2017, it is known that Organizational Prideness is able to increase the pride of lecturers as members of the organization.
Aim: The purpose of this study was to determine the effect of Organizational Prideness as a Nurse on the Extra Role OCB (Organizational Citizenship Behavior) Behavior of Nurses at RSNU Jatim.
Methods: The method in this research uses analytical observational with explanatory type. This study explores the Organizational Prideness of nurses on OCB (Organizational Citizenship Behavior) Extra Role Behavior in the hospital where they work. Data collection was carried out in a crosssectional manner. Respondents were nurses at the East Java Hospital in 2021 with a total of 217 people. The variables studied include the independent variable, namely Organizational Prideness, and the dependent variable is OCB (Organizational Citizenship Behavior) Extra Role Behavior.
Results: The results of this study explain that Organizational Prideness causes OCB (Organizational Citizenship Behavior) Extra Role Behavior to become part of the East Java Hospital. Organizational Prideness is able to improve the Extra Role OCB (Organizational Citizenship Behavior) behavior of nurses towards the East Java Hospital. Organizational Prideness owned by nurses contributes to increasing OCB Extra Role Behavior at RSNU Jatim. Organizational Prideness of nurses is a sense of pride and love when carrying out their duties and responsibilities as nurses at the East Java Hospital. manifested by love, a sense of belonging that is nurtured and continues to grow, Organizational Prideness in this way nurses feel themselves as one unit with the hospital.
Conclusion: The relationship between nurses and colleagues and all employees in the hospital will be harmonious, well maintained and always oriented towards togetherness, understanding, mutual respect and appreciation by upholding tolerance in diversity, which is the embodiment of the implementation of Organizational Prideness and Extra Role Behavior (Organizational Citizenship Behavior).

Published: December 2022

Background: Banyumas Regency is a malaria-receptive area with the occurrence of imported cases, particularly in sub-districts with the potential for transmission and even extraordinary events. To eliminate malaria in the regency, Migration surveillance is needed. Therefore, this study aims to evaluate implementing a malaria migration surveillance system to maintain its elimination status in Banyumas Regency in 2021.
Method: This qualitative case study was conducted in Banyumas Regency with a total of 9 informants consisting of 2 people from the Health Office, 4 from the Community Health Center, 2 from the Health Laboratory, and 1 village head. Data was collected through Forum Group Discussions, in-depth interviews, and secondary data through document review. This study also adopted content analysis with a thematic network approach.
Result: There are several limitations to implementing malaria migration surveillance, namely the lack of human resources, ineffective implementation of village regulations, and the lack of public awareness in reporting symptoms of malaria. Therefore, comprehensive training, policies socialization, improved partnerships, and application-based village reporting are required to maintain the elimination of migration surveillance.

Published: December 2022

Objective

To identify factors associated with work-related issues in Canadian patients with axial spondyloarthritis.

Methods

Data from 542 Canadian patients who participated in the International Map of Axial Spondyloarthritis online survey were analyzed. Participants who were employed, unemployed, or on short-term disability were included in this analysis. Regression analysis was used to study the association between work-related issues, disease activity (Bath Ankylosing Spondylitis Disease Activity Index [BASDAI]), and psychological distress (12-item General Health Questionnaire [GHQ-12]).

Results

The mean age of surveyed participants was 44.3 (SD 13.9) years, 81% were university educated, and 52.6% employed. A substantial proportion had high disease activity (BASDAI ≥ 4, 72.1%) and psychological distress (GHQ-12 ≥ 3, 53.1%); 81% had work-related issues. This study analyzed responses from a subset of participants who were either employed, unemployed, or on short-term disability (n = 339). Ninety percent of this subset reported at least 1 work-related issue in the year before questionnaire completion, with the most frequent being absenteeism (49.3%) and missing work for healthcare provider visits (42.5%). Factoring in disability benefits eliminated the association between work-related issues and disease activity for all variables except fatigue (r= 0.217;P= 0.03) and discomfort (r= 0.196;P= 0.047). Difficulty fulfilling working hours (β 2.342, 95% CI 1.413-3.272) and effect on professional advancement (β 1.426, 95% CI 0.355-2.497) were associated with psychological distress. In the presence of disability benefits, only the effect on professional advancement remained (β 2.304, 95% CI 0.082-4.527).

Conclusion

Work-related issues are associated with worse patient-reported outcomes, both physical and psychological.

Published: December 2022

Objective

Nailfold capillaroscopy (NFC) is increasingly used in the early identification of systemic sclerosis (SSc)-related disorders. A consensus "Fast Track algorithm" was developed by the European Alliance of Associations for Rheumatology to aid differentiation of scleroderma from nonscleroderma pattern on NFC. Our objective was to evaluate the online training of NFC using the Fast Track algorithm in the assessment of scleroderma vs nonscleroderma NFC pattern.

Methods

Participants attended the NFC online training workshop and were taught the Fast Track algorithm. Following the training, participants independently evaluated 45 NFC images in the same session, and then 2 to 4 weeks later, through the online platform. Participants had to differentiate between scleroderma vs nonscleroderma pattern, and additionally nonscleroderma pattern (normal) vs nonscleroderma pattern (nonspecific). The inter- and intrarater Cohen κ agreement was calculated.

Results

Ninety-eight participants took part in the baseline evaluation, and 61 in the reevaluation session. For identification of scleroderma vs nonscleroderma pattern, the mean (95% CI) inter- and intrarater κ were 0.86 (0.83-0.88) and 0.83 (0.79-0.87), respectively. The overall inter- and intrarater κ in the identification of scleroderma, nonscleroderma (normal), and nonscleroderma (nonspecific) patterns were 0.71 (0.69-0.74) and 0.71 (0.67-0.75), respectively. For nonscleroderma (normal) vs nonscleroderma (nonspecific) pattern, the inter- and intrarater κ were 0.59 (0.55-0.63) and 0.59 (0.54-0.65), respectively.

Conclusion

In this first study evaluating NFC online training using the Fast Track algorithm, we showed very good inter- and intrarater agreement for the identification of scleroderma and nonscleroderma NFC pattern, supporting the feasibility of online NFC standardized training workshops.

Published: December 2022

Le 28 juillet 2021, Agnès Pannier-Runacher et Cédric O ont signé avec les professionnels de la logistique et du e-commerce des chartes d’engagement et indiqué à cette occasion qu’avant la fin de l’année 2021 le gouvernement organiserait dans chaque région une conférence sur la logistique. En Bourgogne-Franche-Comté, l’État a lancé un certain nombre de travaux sur la logistique, à la suite des travaux initiés par la mission interministérielle pour le développement de l’axe portuaire et logistique de l’axe Méditerranée-Rhône-Saône (DIMeRS). Une enquête a été menée en 2021 auprès d’un panel d’acteurs des transports et de la logistique, afin de recueillir leurs attentes et leurs propositions. Ce travail a fait l’objet d’une restitution en juin 2021 auprès des membres de l’observatoire régional des transports (ORT). Cette étude a fait émerger six thématiques de travail prioritaires : la définition d’une identité logistique régionale ; l’emploi et la formation ; la multimodalité ; l’innovation logistique ; la transition énergétique ; l’aménagement logistique. Chacune de ces thématiques a fait l’objet d’un atelier participatif. La journée du 1er décembre 2021 a marqué le lancement de la démarche avec deux premiers ateliers. Les quatre autres ateliers ont eu lieu les 24 février et 24 mars 2022. La démarche suscite un vif intérêt des professionnels et des institutionnels présents qui en attendent une suite opérationnelle. Elle doit à présent s’inscrire dans la durée. La prochaine étape, lancée à partir de l’été 2022, consiste à co-construire avec toutes les parties prenantes, une stratégie régionale de la logistique, structurée par un plan d’action.

Il avait pris la défense du peuple Enawenê-Nawê, dont il était venu à partager la vie après plusieurs années d’engagement dans la pastorale missionnaire indigène. Si Cañas a laissé peu d’écrits, sa vie elle-même semble esquisser une proposition théologique, encore en attente d’être explicitée.
L’effondrement psychique et sociétal : ne pas tomber en dessous de soi-même
Authors: Ostermann Gérard , Lesœurs Guy
Published: December 2022

Le terme effondrement est polysémique. Géologie, architecture, finances, sociétés, espèces animales…, l’effondrement s’applique également et plus insidieusement à la culture et aux valeurs. En santé, l’effondrement évoque la décompensation de l’état d’homéostasie somatique et la perte de l’équilibre psychique. La personne n’est plus capable de mobiliser son énergie vitale ni ses mécanismes de défense pour supporter l’angoisse de mort qui l’envahit. L’analogie entre l’effondrement individuel et sociétal a fait réfléchir les auteurs de cet article, psychothérapeutes, sur la sinistrose, le malaise ambiant et la perte de sens rassemblés de manière plus concrète sous le terme anglais brown-out , état de morosité et de pré-effondrement qui précède le black-out  ; ce dernier, synonyme littéral d’extinction. Prenant comme base le texte de D.W. Winnicott « La crainte de l’effondrement » [1], les auteurs insistent sur le fait que l’effondrement, annoncé par les Cassandre et collapsologues de tous bords, n’est pas irrémédiable si nous reprenons confiance en nous, en notre avenir et si nous ravivons nos valeurs humanistes afin de ne pas se laisser entraîner dans un maelstrom mortifère.
Pratiques innovantes : l’accompagnement médical par le trépied du vivant dans les MICI/SII
Authors: Bonnaud Guillaume , Feuché Nathalie , Tesiorowski Flore , Costil Guillaume
Published: December 2022

La prise en charge médicale actuelle des maladies chroniques digestives comme les MICI et les troubles fonctionnels intestinaux est essentiellement technique et centrée sur le médicament. Les progrès de l’industrie pharmaceutique ont permis une amélioration incontestable de l’évolution symptomatique et pronostique des maladies chroniques. Cependant, à lui seul, le médicament a souvent une efficacité partielle et ne permet pas un retour à une vie équilibrée, normale chez un patient porteur d’une maladie chronique. Face à ce constat, les patients se tournent, pour au moins la moitié d’entre eux, vers des thérapies complémentaires. Toutes ces thérapies s’intègrent dans le cadre de ce que l’on nomme la médecine intégrative ou interventions non médicamenteuses, et permettent une prise en charge globale de l’individu au-delà du médicament. Il apparaît important d’encadrer scientifiquement et médicalement cet accompagnement holistique du patient au-delà du médicament. Nous proposons dans cet article de se centrer sur des recommandations sur le trépied fondamental de la prise en charge holistique qui concerne la nutrition, l’activité physique, la régulation du stress et des émotions. La prise en charge de ce trépied du vivant, en dehors de pratiques simples, peut utiliser des techniques comme le yoga, la cohérence cardiaque, la méditation pleine conscience, l’hypnose, les thérapies d’activation de la conscience. Au-delà d’une prise en charge physique classique par des professionnels de santé, les outils digitaux peuvent être un atout complémentaire important pour diffuser des informations validées et favoriser les changements de comportement au long cours.

Cet article propose une approche de la façon dont les éducateurs et éducatrices spécialisés envisagent la question de la distance et de son double, la proximité, des années 1940 aux années 1960. En s’appuyant principalement sur les archives de leur association professionnelle, il est ainsi possible de distinguer un premier temps, durant lequel l’installation d’éducateurs a pour objet d’établir une plus grande proximité avec les jeunes placés afin de rompre avec les héritages correctionnels, passant notamment par le « vivre avec ». Mais la professionnalisation suscite des débats sur le don de soi et entraîne une « prise de recul » au fil des années 1950, par laquelle la prise de distance physique et technique entre éducateurs et jeunes s’accompagne également d’une distance des éducateurs avec leur outil de travail, à savoir eux-mêmes.
A mathematical model for inducing T-cells around tumor cells by using exchanged waves between graphene sheets interior and exterior of body
Authors: Fioranelli Massimo , Ahmad Hijaz , Roccia Maria Grazia , Beesham Aroonkumar , Shah Zahir
Published: December 2022

We propose a theoretical model which helps us to use entangled graphene sheets for inducing T-cells around tumor cells. The direction of the free spinors on a graphene sheet should be in the opposite direction to the direction of the free spinors on the other graphene sheet in an entangled system. Consequently, any change in one sheet could be understood by spinors in the other sheet. One of these graphene sheets plays the role of antenna within the human body, and the other one acts as the sender exterior to it. With time and the motion of the total wave, the graphene sheet divides into smaller components with lower energy on some circles, and the centre of such a circle is the sender. Thus, to provide the required energy for activation of the interior graphene sheet, we add more sheets or increase the external potential exterior to the body. According to the Warburg proposal, radiated spinors from normal cells and cancer cells are different, and these differences could be seen by free spinors on the exterior of the graphene sheets. When the existence of a tumor is diagnosed, some T-cells could be close to the exterior graphene sheets. Free spinors on these sheets change, take the shape of T-cells and transmit information to the interior sheet. Spinors on this sheet produce virtual T-cells which deceive the tumor cells and produce virtual PD1/PD-L1 connections with them. Consequently, tumor cells cannot introduce death toxins into real T-cells, and these cells have the opportunity to destroy them.

Published: December 2022

The notion of the bipolar complex fuzzy set (BCFS) is a fundamental notion to be considered for tackling tricky and intricate information. Here, in this study, we want to expand the notion of BCFS by giving a general algebraic structure for tackling bipolar complex fuzzy (BCF) data by fusing the conception of BCFS and semigroup. Firstly, we investigate the bipolar complex fuzzy (BCF) sub-semigroups, BCF left ideal (BCFLI), BCF right ideal (BCFRI), BCF two-sided ideal (BCFTSI) over semigroups. We also introduce bipolar complex characteristic function, positive $ \left(\omega , \eta \right) $-cut, negative $ \left(\varrho , \sigma \right) $-cut, positive and $ \left(\left(\omega , \eta \right), \left(\varrho , \sigma \right)\right) $-cut. Further, we study the algebraic structure of semigroups by employing the most significant concept of BCF set theory. Also, we investigate numerous classes of semigroups such as right regular, left regular, intra-regular, and semi-simple, by the features of the bipolar complex fuzzy ideals. After that, these classes are interpreted concerning BCF left ideals, BCF right ideals, and BCF two-sided ideals. Thus, in this analysis, we portray that for a semigroup $ Ş $ and for each BCFLI $ {М}_{1} = \left({\mathrm{\lambda }}_{P-{М}_{1}}, {\mathrm{\lambda }}_{N-{М}_{1}}\right) = \left({\mathrm{\lambda }}_{RP-{М}_{1}}+\iota {\mathrm{\lambda }}_{IP-{М}_{1}}, {\mathrm{\lambda }}_{RN-{М}_{1}}+\iota {\mathrm{\lambda }}_{IN-{М}_{1}}\right) $ and BCFRI $ {М}_{2} = \left({\mathrm{\lambda }}_{P-{М}_{2}}, {\mathrm{\lambda }}_{N-{М}_{2}}\right) = \left({\mathrm{\lambda }}_{RP-{М}_{2}}+\iota {\mathrm{\lambda }}_{IP-{М}_{2}}, {\mathrm{\lambda }}_{RN-{М}_{2}}+\iota {\mathrm{\lambda }}_{IN-{М}_{2}}\right) $ over $ Ş $, $ {М}_{1}\cap {М}_{2} = {М}_{1}⊚{М}_{2} $ if and only if $ Ş $ is a regular semigroup. At last, we introduce regular, intra-regular semigroups and show that $ {М}_{1}\cap {М}_{2}\preccurlyeq {М}_{1}⊚{М}_{2} $ for each BCFLI $ {М}_{1} = \left({\mathrm{\lambda }}_{P-{М}_{1}}, {\mathrm{\lambda }}_{N-{М}_{1}}\right) = \left({\mathrm{\lambda }}_{RP-{М}_{1}}+\iota {\mathrm{\lambda }}_{IP-{М}_{1}}, {\mathrm{\lambda }}_{RN-{М}_{1}}+\iota {\mathrm{\lambda }}_{IN-{М}_{1}}\right) $ and for each BCFRI $ {М}_{2} = \left({\mathrm{\lambda }}_{P-{М}_{2}}, {\mathrm{\lambda }}_{N-{М}_{2}}\right) = \left({\mathrm{\lambda }}_{RP-{М}_{2}}+\iota {\mathrm{\lambda }}_{IP-{М}_{2}}, {\mathrm{\lambda }}_{RN-{М}_{2}}+\iota {\mathrm{\lambda }}_{IN-{М}_{2}}\right) $ over $ Ş $ if and only if a semigroup $ Ş $ is regular and intra-regular.
Four decades of Canadian earnings inequality and dynamics across workers and firms
Authors: Bowlus Audra , Gouin-Bonenfant Émilien , Liu Huju , Lochner Lance , Park Youngmin
Published: December 2022

This paper studies the evolution of individual earnings inequality and dynamics in Canada from 1983 to 2016 using tax files and administrative records. Linking individual tax filers to their employers (and rich administrative records on firms) beginning in 2001, it also documents the relationship between the earnings dynamics of workers and the size and growth of their employers. It highlights three main patterns over this period: First, with a few exceptions (sharp increase in top 1% and declining gender gap), Canada has experienced relatively modest changes in overall earnings inequality, volatility, and mobility between 1983 and 2016. Second, earnings inequality and the distribution of earnings growth vary substantially over the business cycle. Third, the earnings dynamics of individuals are strongly related to the size and employment growth of their employers.
Inequality, income dynamics, and worker transitions: The case of Mexico

Published: December 2022

We characterize the salient features of the distribution of (log) earnings of formal workers in Mexico using social security records for the period 2005–2019. The analysis is based on a nonparametric approach and is focused primarily on the properties of the distribution of earnings changes. We find strong evidence of deviations from normality of this distribution in terms of negative skewness and high kurtosis, with these deviations varying with income and along the worker's life cycle. A comparison between results obtained with administrative data and household survey data suggests that this latter source of information is inadequate to fully capture the evolution of inequality and the properties of earnings changes as nonresponse is nonrandom and concentrated among formal and highly educated workers—likely the highest earners. Due to the relative size of the informal sector in the Mexican economy, which results in a large number of workers maintaining a weak attachment to formal employment, we also study the impact of transitions out of and back into formal employment on wages earned in the formal sector. We document that workers who exit formal employment experience a significant wage penalty upon reentry taking, on average, 3 or more years to achieve comparable preexit wage levels.

Du lieu de production à la production des lieux : histoire socio-matérielle de la brasserie Gruber dans son contexte territorial
Authors: Handtschoewercker Nicolas
Published: December 2022

L’approche par le métabolisme est-elle porteuse de nouveaux récits concernant le développement urbain moderne ? Nous proposons dans cet article de retracer l’histoire conjointe de la brasserie Gruber et de son contexte territorial. Par la mise en relation matérielle de différentes échelles territoriales, l’usine s’affirme au tournant du XXe siècle comme une des plus importantes brasseries industrielle d’Alsace, tandis que le faubourg dans lequel elle s’implante mute dans sa matérialisation et ses usages. Par l’étude socio-matérielle de son métabolisme, il s’agit alors d’appréhender en quoi l’usine Gruber caractérise un double processus de transformation de son environnement, à la fois consommation (matières premières, force de travail) et production de celui-ci (usages, sociabilités et spatialités).
Torre David au Venezuela : récits sur fond de politiques publiques menées par le gouvernement d’un « État magique »
Authors: Wilson Yaneira
Published: December 2022

De Hugo Chávez à Nicolás Maduro, le Venezuela a engagé depuis 1999 un ensemble de réformes désignées sous le nom de « révolution bolivarienne ». Dans ce cadre, nous nous intéressons à explorer la production de la Grande Mission Logement Venezuela (GMVV) et le cas de l’invasion de la Torre David squattée en 2004 par un premier groupe de sans-abri. Les principales questions : comment l’État « magique » avec sa dépendance historique aux ressources pétrolières peut-il viser une solution aux problèmes de logements rencontrés par la société ? Désossée, abandonnée, toujours saillante, la Torre David est passée d’icône de la modernité à l’écriture d’un avenir « incertain » dans laquelle la société vénézuélienne est plongée. En 2022, la Torre symbolise encore une crise latente qui perdure sans donner d’indices sur son cours final.
Coécrire l’histoire locale face à la démolition des quartiers populaires, de Plaisir (France) à Belo Horizonte (Brésil)
Authors: Duclos Elise Havard dit , Urvoy Philippe
Published: December 2022

Tandis que les quartiers populaires sont profondément remodelés, voire partiellement démolis, dans le cadre des opérations de rénovation urbaine, la valorisation de leur histoire s’institutionnalise comme nouvel élément intégré à l’arsenal opérationnel de ces projets. Certains auteurs s’interrogent sur le sens de telles initiatives, étant associées à des interventions urbaines qui amputent ces quartiers d’une partie de leur patrimoine, souvent sans réelle concertation des habitants. À rebours de cette posture mémorielle descendante, on observe ces dernières années des initiatives mises en place par des groupes d’habitants, visant à valoriser l’histoire de leur quartier pour s’opposer à des projets de démolitions imposés par les pouvoirs publics. Ces démarches, avec le soutien de groupes universitaires, donnent lieu à une coproduction singulière de l’histoire locale. Le présent article se propose d’analyser deux de ces expériences, dans des quartiers populaires aux profils urbains distincts : au Valibout (Plaisir — France) et dans la Vila das Antenas (Belo Horizonte, Brésil). Dans ces deux quartiers, de telles recherches collaboratives ont été mises en place ces dernières années dans le cadre de mobilisations contre des projets de rénovation urbaine portés par les municipalités. L’analyse comparative proposée associe une démarche d’observation participante à des entretiens conduits avec des chercheurs et habitants impliqués dans ces recherches. Il s’agira d’interroger les enjeux méthodologiques, épistémologiques et politiques de ces expériences afin de comprendre leurs effets sur les mobilisations habitantes, sur la production des connaissances historiques mais aussi sur la fabrique de la ville.
Histoires et pratiques dissonantes dans un ghetto en devenir. Anthropologie contemporaine du cas de Venise
Authors: Trani Antonella Di
Published: December 2022

Pris dans de récentes transformations sociales et matérielles, le ghetto de Venise et son dense passé historique font l’objet de réappropriations de la part des acteurs impliqués dans son processus de revitalisation. L’espace du ghetto devient un lieu d’enjeux, de pratiques dissonantes où établis ou nouveaux arrivants ayant une trajectoire résidentielle et des appartenances diverses tentent de réinventer le ghetto en devenir alors qu’il a les traits d’un lieu ambivalent. L’histoire et les récits du ghetto s’en trouvent réactivés. Les usages de l’espace réactualisés font émerger des conflits de visibilité et de représentation d’une forme de vie juive en ce lieu emblématique, ce qui contribue à reconsidérer le terme de ghetto.Ghetto, Temporalités, Mode d’appartenance, Histoire locale, Récits d’acteurs
