COVID-19 and the Environmental Regulatory Response: Compendium of Regulatory, Ad Hoc Changes and Implications
Authors: Nyiwul Linus Mabughi
Published: February 2023

Using open source and official documents, we documented and analyzed changes in environmental regulations in response to the COVID-19 pandemic. We accumulated 71 such regulatory changes across 29 countries, spanning several environmental sectors, between March and July 2020. The objective of our analysis is to characterize trends, impacts and implications of regulatory changes adopted in response to COVID-19. Our analysis contributes to understanding the types and nature of changes that the pandemic may induce in environmental policy through behavioral changes and resource use. Examination of the data shows that countries around the globe largely pursued rollbacks and enforcement relief in response to COVID-19. However, developing countries in our data were more likely to tighten environmental regulations compared to developed economies, where steps towards deregulation dominated regulatory changes. The data also shows that actions in the energy sector were geared toward deregulation. Air quality and biodiversity regulations were rolled back in response to the COVID-19 pandemic, despite rising concerns about the links between the coronavirus and pollution, wildlife, and habitat destruction. It can be concluded that the nature and type of changes in environmental regulations across countries in response to COVID-19 depended on a country’s economic development status and that the degree of regulatory changes across different sectors was driven by the differences in the social and economic impacts of the pandemic.

NVH testing is an inseparable part of the automotive product and component design and development process. With the global shift towards hybrid and electric vehicles, it is important to understand the NVH characteristics of electric power trains. Brushless DC (BLDC) motors are the most commonly used electric vehicle motors but one of their major drawbacks is the acoustic noise and vibration caused by torque ripples. This project investigates the source of noise and vibration in an 800 W BLDC hub Motor used in an Electric Scooter. A 3D model has been generated approximately to the real life model then Modal analysis using FEM is performed using Ansys to determine the natural frequency of the vibrating parts of the motor in static conditions. The results of these simulations are to be compared and validated experimentally. The dynamic condition frequencies are also determined. It also deals experimental Noise Analysis.

Published: February 2023

Sandwich panel with laminate faces is used for free vibration analysis. The periodic microstructure and Mori- Tanaka model are used for homogenization of unidirectional fiber reinforced composite. The Shear Deformation Theory is considered for analytical and numerical analysis. FEM in ANSYS is used for numerical analysis. The effect of sandwich design parameters such as panel length, core thickness and fiber reinforced angle on vibration response is investigated. Natural frequencies of sandwich panel versus sandwich design parameters are presented in graphical form. From the results can be concluded that sandwich design parameters affect the natural frequencies of sandwich panels, and this effect is important for designing of sandwich panels under dynamic load.

Countermeasures of Regulations on the Prevention of Overseas Mixed Organizations of Domestic Pension Funds : Focusing on OECD BEPS Action2
Authors:   KOREAN SOCIETY OF TAX LAW, Kim Su-Sung
Published: February 2023

This study attempted to examine the countermeasures against overseas reverse hybrid organizations for domestic pension funds by implementing the Base Erosion and Profit Shifting(BEPS) prevention agreement in OECD’. BEPS refers to the act of avoiding taxes by using not only differences in tax laws between the two countries but also deficiencies in tax treaties. In 2015, the BEPS prevention agreement was signed at the G20 summit. It is to strengthen tax-related standards and secure tax certainty by sharing corporate transaction-related information.
Currently, SPC established overseas is defined as an ‘overseas corporation’. However, it is recognized as a ‘conductor organization’ overseas. For this reason, SPC is defined as a reverse hybrid organization. If SPC is defined as a reverse-mixed organization, income that has not been previously taxed will be taxed at a 25% tax rate in EU countries, and additional taxes will be levied at a 30% tax rate. In consideration of this situation, this study
intends to examine the problems and countermeasures of the regulations for preventing foreign mixed-sex organizations. This study attempted to present a specific plan to establish a legal basis for clearly considering SPCs established overseas as conduit organizations, focusing on OECD BEPS Action2. This study is meaningful in that it examined the international tax response measures of institutional investors, including domestic pension funds.
A Study on the Introduction of Inheritance Tax System to resolve Income Inequality in China
Authors:   KOREAN SOCIETY OF TAX LAW, Li Xue Cheng , Suh Jung Woo
Published: February 2023

Inheritance tax in China was first implemented during the Republic of China era. At that time, the Nanjing government proposed imposing an inheritance tax and enacted related ordinances, but it was not implemented.
However, after the Anti-Japanese War broke out on July 1, 1940 and the national finances were in crisis, inheritance tax was officially imposed.
However, inheritance tax was proposed several times as one of the taxes imposed after the founding of New China, but all of them were postponed.
As the Chinese economy has grown rapidly since the reform and opening up and the gap between the rich and the poor has widened, personal income tax can no longer meet the need to adjust the income gap. As a policy tool to control this and as a way to narrow the income gap, the question of whether or not to impose inheritance tax has been revisited. It was once the people’s choice. However, considering the current situation of China’s economic level and the gap between the rich and the poor, the introduction of the inheritance tax is considered sufficient.
Inheritance tax also has a positive meaning in improving the national tax system, properly adjusting the distribution of wealth among members of society, increasing financial resources for the government and social welfare programs, and maintaining national income.
Therefore, in order for China to introduce and actually implement the inheritance tax system, it is necessary to establish a theoretically desirable basic direction. In other words, it is very important to clearly establish the
purpose pursued by the national policy and to establish the basic direction to achieve the purpose well.
On the other hand, when introducing the inheritance tax system, the tax conditions such as which inheritance tax method to choose, whether to separate or integrate with the gift tax, the determination of the minimum tax amount, and the tax rate should be tailored to the actual situation in China in consideration of the inheritance tax legislative principle, efficiency and fairness. You will have to decide. In addition, research on countries that are currently successfully operating the inheritance tax system and specific plans for detailed components to suit China’s situation should be established.
This study focused on the implementation (proposal) of the Inheritance Tax Law, which was reviewed by the Chinese Ministry of Finance in 2010, and further research by experts is also required.
A Study on the Improvement of Insurance Taxation System - Focusing on Inheritance and Gift Tax Law -
Authors:   KOREAN SOCIETY OF TAX LAW, Baek Seung-Sam , Kim Byung-Il
Published: February 2023

Insurance contracts go beyond the main function of insurance and have the nature of similar financial products such as deposits, savings, and funds, through which they are used as a means of transfer of wealth between
families and the uptake of property. As such, insurance products continue to diversify, but the basis for insurance-related tax revenue is not yet clear, so it is possible to violate tax law. For this, we would like to propose an improvement plan that takes into account the following problems.
First, there are definitions, scopes, and requirements for death insurance due to injury in commercial law. Therefore, the inheritance tax and gift tax law has no choice but to understand the concept of insurance as a borrowing concept, so it is difficult to tax based on this. In order to solve this problem, it is necessary to clarify the basis for the imposition of inheritance tax and gift tax by explicitly stipulating the nature and scope of insurance premiums, through the amendment of the Commercial Act. Second, it is necessary to clarify the scope of the interpretation of the ‘insurance contract period’ in Article 34(1)(2) of the Inheritance Tax and Assignment Tax Act. In other words, rather than interpreting on the ‘insurance contract period’ in Article 34 (1) of the same Act, it is necessary to judge the possibility of paying insurance premiums for those who have been gifted from others (the parties) according to their economic substance, rather than interpreting them based on the legal provisions or the concept of complete over the concept of complete coverage. Third, unlike the change of the insured beneficiary, the change of the insurance contractor will fall under the insurance transfer under the insurance law, and the nature of the insurance transfer will be estimated to be com-prehensive succession. Based on the estimated concept of comprehensive succession under the insurance law, it is possible to view the change time of the policyholder as the gift time to ensure legal stability, and the purpose of determining the tax base and tax amount as soon as possible can be achieved in terms of the tax law.
EDUCATION BARRIERS AND POLICY OPPORTUNITIES IN CONFLICT-AFFECTED FRAGILE ZONES
Authors: Ilyas Mohammad
Published: February 2023

Throughout the twentieth century, globally, the number of armed conflicts has risen considerably. These conflicts have resulted in a large number of deaths, as well as widespread displacement, terror, and economic damage. One of the most significant hurdles to children obtaining a proper primary education today is conflict-affected conditions, insecurity, and instability. Conflict is a key hindrance to achieving the SDGs, which include universal primary school completion. More than half of the primary-school-aged children of the world are expected to resides in conflict nations afflicted by war. When institutions are lacking capability, responsibility, or legitimacy to manage interactions between citizen and the state, people and the state become exposed to violence. Children are impacted by violence in a number of ways, ranging from injuries to death or to more long-lasting and irreparable effects on their education, health, nutrition, aspirations, and psycho-social well-being. Exposure to violence has a negative impact on children's educational achievement. Education, on the other hand, is increasingly recognized as having a role in preventing and/or worsening conflict. The purpose of this paper is to identify questions that have been addressed in previous systematic research about how children's education has been impacted, what are the barriers stand in the way of achieving the universal goal of education, and what implications living in conflict has for children's educational needs. In addition, this article will consider how educational policies and initiatives might offer a safe environment for children living in war or post-conflict settings.

Published: February 2023

A smartphone, tablet, or personal computers can be tremendously valuable tools. Routine usage of these gadgets can hinder with work, academics, and relations. When more time is spent on electronics compared to that of real people in the surroundings, one cannot stop themselves from frequently checking sms, mails or other apps- even if it creates a negative impact in their life. People rely heavily on mobile phones for their means of communication, entertainment and distraction. On an average a person checks at the phone 150 times per day or one time in every 6.5 minutes. Following objectives are used in this
1. Assess the prevalence of Smart Phone Addiction
2. To assess the reasons of usage of smart phone excessively
3. Adverse effects of Smart Phone Addiction
In this multistage and convenient sampling methods were used to select 600 students of colleges of Ahmedabad, Gujarat. According to AMC-Ahmedabad Municipal Corporation, the city is divided into 6 zones, and therefore one college was selected from each zone, 100 students from that college were selected and interviewed regarding their socio-demographic profile and behavioral change.
Smartphone addiction was found more in females. It showed a significant correlation with stress, internet addiction, anxiety and sleep quality. 100% of the students reported the habit of using mobile phone before going to bed at night. Cramer’s V was used to check the association of smart phone with sleep quality, physical activity and were found significant. The results showed that physical activity was negatively associated to smart phone addiction. While children belonging to high economic status with smart phone addiction were less compared to the lower economic status. Increasing socioeconomic status increased number of smokers, alcoholics and obese people. Most of the students used mobile phones for communication, entertainment and distraction instead of learning new things or for academic purpose. Majority of students suffered from internet addiction and anxiety. Lack of attention was developed into conversations and real life. The self-esteem got lowered and academic performances deteriorated after they started using mobile phones. Increase in motor vehicle accidents due to mobile phones was also noticed.
Impact of Correlated Noise on the Mass Precision of Earth-analog Planets in Radial Velocity Surveys

Published: February 2023

Characterizing the masses and orbits of near-Earth-mass planets is crucial for interpreting observations from future direct imaging missions (e.g., HabEx, LUVOIR). Therefore, the Exoplanet Science Strategy report recommended further research so future extremely precise radial velocity surveys could contribute to the discovery and/or characterization of near-Earth-mass planets in the habitable zones of nearby stars prior to the launch of these future imaging missions. Newman et al. (2023) simulated such 10 yr surveys under various telescope architectures, demonstrating they can precisely measure the masses of potentially habitable Earth-mass planets in the absence of stellar variability. Here, we investigate the effect of stellar variability on the signal-to-noise ratio (S/N) of the planet mass measurements in these simulations. We find that correlated noise due to active regions has the largest effect on the observed mass S/N, reducing the S/N by a factor of ∼5.5 relative to the no-variability scenario; granulation reduces by a factor of ∼3, while p-mode oscillations has little impact on the proposed survey strategies. We show that in the presence of correlated noise, 5 cm s−1 instrumental precision offers little improvement over 10 cm s−1 precision, highlighting the need to mitigate astrophysical variability. With our noise models, extending the survey to 15 yr doubles the number of Earth-analogs with mass S/N > 10, and reaching this threshold for any Earth-analog orbiting a star >0.76 M
⊙ in a 10 yr survey would require an increase in the number of observations per star from that in Newman et al. (2023).
Untangling the Sources of Abundance Dispersion in Low-metallicity Stars
Authors: Griffith Emily J. , Johnson Jennifer A. , Weinberg David H. , Ilyin Ilya , Johnson James W. , Rodriguez-Martinez Romy , Strassmeier Klaus G.
Published: February 2023

We measure abundances of 12 elements (Na, Mg, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni) in a sample of 86 metal-poor (−2 ≲ [Fe/H] ≲ −1) subgiant stars in the solar neighborhood. Abundances are derived from high-resolution spectra taken with the Potsdam Echelle Polarimetric and Spectroscopic Instrument on the Large Binocular Telescope, modeled using iSpec and MOOG. By carefully quantifying the impact of photon-noise (<0.05 dex for all elements), we robustly measure the intrinsic scatter of abundance ratios. At fixed [Fe/H], the rms intrinsic scatter in [X/Fe] ranges from 0.04 (Cr) to 0.16 dex (Na), with a median of 0.08 dex. Scatter in [X/Mg] is similar, and accounting for [α/Fe] only reduces the overall scatter moderately. We consider several possible origins of the intrinsic scatter with particular attention to fluctuations in the relative enrichment by core-collapse supernovae (CCSN) and Type Ia supernovae and stochastic sampling of the CCSN progenitor mass distribution. The stochastic sampling scenario provides a good quantitative explanation of our data if the effective number of CCSN contributing to the enrichment of a typical sample star is N ∼ 50. At the median metallicity of our sample, this interpretation implies that the CCSN ejecta are mixed over a gas mass ∼6 × 104
M
⊙ before forming stars. The scatter of elemental abundance ratios is a powerful diagnostic test for simulations of star formation, feedback, and gas mixing in the early phases of the Galaxy.
Evolving Morphology of Resolved Stellar Einstein Rings
Authors: Turyshev Slava G. , Toth Viktor T.
Published: February 2023

We consider strong gravitational lensing by nearby stars. Using our wave-optical treatment of lensing phenomena, we study Einstein rings that may form around nearby stellar lenses. It is remarkable that these rings are bright and large enough to be detected and resolved by existing instruments. Such lensing events have durations of hours or days, with peak light amplification lasting for several minutes. Many such events may be predicted using the Gaia astrometric catalog. Serendipitous discoveries are also possible. Fortuitous alignments can be used to confirm or discover and study exoplanets. For lenses that have dense stellar regions in their background, these events may occur several time a year, warranting their continuous or recurrent monitoring. Resolved imaging and spectroscopy of the evolving morphology of an Einstein ring offers knowledge about both the lens and the source. The angular size of the Einstein ring amounts to a direct measurement of the lens mass. The changing orientation of the major and minor images of the source offers astrometric information related to the mutual orientation of the objects. The event duration, when the full ring is present, helps to determine the source’s size. The sky position of planetary lensing events constrains the planet’s orbit. Spectroscopy of the ring allows for direct investigations of the source. The frequency and predictability of these events and the wealth of information that can be obtained by imaging motivate observational campaigns using existing facilities and/or construction of new instruments dedicated to the search and study of Einstein rings that are forming around nearby stars. As a specific example, we consider a predicted 2028 lensing of a red giant by α Centauri A and discuss the relevant science campaign.
Modeling CO Line Profiles in Shocks of W28 and IC 443
Authors: Fuda Nguyen , Tram Le Ngoc , Reach William T.
Published: February 2023

Molecular emission arising from the interactions of supernova remnant (SNR) shock waves and molecular clouds provide a tool for studying the dispersion and compression that might kick-start star formation as well as understanding cosmic-ray production. Purely rotational CO emission created by magnetohydrodynamic shock in the SNR–molecular cloud interaction is an effective shock tracer, particularly for slow-moving, continuous shocks into cold inner clumps of the molecular cloud. In this work, we present a new theoretical radiative transfer framework for predicting the line profile of CO with the Paris–Durham 1D shock model. We generated line profile predictions for CO emission produced by slow, magnetized C shocks into gas of density ∼104 cm−3 with shock speeds of 35 and 50 km s−1. The numerical framework to reproduce the CO line profile utilizes the large velocity gradient (LVG) approximation and the omission of optically thick plane-parallel slabs. With this framework, we generated predictions for various CO spectroscopic observations up to J = 16 in SNRs W28 and IC 443, obtained with SOFIA, IRAM-30 m, APEX, and KPNO. We found that CO line profile prediction offers constraints on the shock velocity and pre-shock density independent of the absolute line brightness and requires fewer CO lines than diagnostics using a rotational excitation diagram.
Lithium Abundances in Giants as a Function of Stellar Mass: Evidence for He Flash as the Source of Li Enhancement in Low-mass Giants
Authors: Mallick Anohita , Singh Raghubar , Reddy Bacham E.
Published: February 2023

In this work, we studied the distribution of lithium abundances in giants as a function of stellar mass. We used a sample of 1240 giants common among Kepler photometric and LAMOST medium-resolution (R ≈ 7500) spectroscopic survey fields. The asteroseismic ΔP–Δν diagram is used to define core He-burning red clump giants and red giant branch stars with an inert He core. Li abundances have been derived using spectral synthesis for all sample stars. Directly measured values of asteroseismic parameters ΔP (or ΔΠ1) and Δν are either taken from the literature or measured in this study. Of the 777 identified red clump giants, we found 668 low-mass (≤2 M
⊙) primary red clump giants and 109 high-mass (>2 M
⊙) secondary red clump giants. Observed Li abundances in secondary red clump giants agree with the theoretical model predictions. The lack of Li-rich giants among secondary red clump giants and the presence of Li-rich, including super Li-rich, giants among primary red clump stars reinforces the idea that helium flash holds the key for Li enrichment among low-mass giants. The results will further constrain theoretical models searching for a physical mechanism for Li enhancement among low-mass red clump giants. Results also serve as observational evidence that only giants with mass less than ≈2 M
⊙ develop a degenerate He core and undergo He flash.

We report the discovery of two extremely magnified lensed star candidates behind the galaxy cluster MACS J0647.7+015 using recent multiband James Webb Space Telescope (JWST) NIRCam observations. The star candidates are seen in a previously known, z
phot ≃ 4.8 dropout giant arc that straddles the critical curve. The candidates lie near the expected critical curve position, but lack clear counter-images on the other side of it, suggesting these are possibly stars undergoing caustic crossings. We present revised lensing models for the cluster, including multiply imaged galaxies newly identified in the JWST data, and use them to estimate background macro-magnifications of at least ≳90 and ≳50 at the positions of the two candidates, respectively. With these values, we expect effective, caustic-crossing magnifications of ∼[103–105] for the two star candidates. The spectral energy distributions of the two candidates match well the spectra of B-type stars with best-fit surface temperatures of ∼10,000 K, and ∼12,000 K, respectively, and we show that such stars with masses ≳20 M
⊙ and ≳50 M
⊙, respectively, can become sufficiently magnified to be observable. We briefly discuss other alternative explanations and conclude that these objects are likely lensed stars, but also acknowledge that the less-magnified candidate may alternatively reside in a star cluster. These star candidates constitute the second highest-redshift examples to date after Earendel at z
phot ≃ 6.2, establishing further the potential of studying extremely magnified stars at high redshifts with JWST. Planned future observations, including with NIRSpec, will enable a more detailed view of these candidates in the near future.

Published: February 2023

BACKGROUND: Alpha-fetoprotein (AFP) is the recommended screening biomarker for hepatocellular carcinoma (HCC), despite its drawbacks: AFP-negative HCC, poor specificity, and sensitivity. As a result, new HCC-sensitive and specific biomarkers are urgently needed.
AIM: This study aimed to determine the diagnostic value of transforming growth factor (TGF)-β1 mRNA and Annexin II in the early detection and follow-up of HCC.
PATIENT AND METHODS: This research involved 75 HCC patients (30 early and 45 late) and 75 liver cirrhosis (LC) patients (all patients have HCV), and 75 healthy individuals as controls. Reverse transcription polymerase chain reaction measured TGF-β1 mRNA. Enzyme-linked immunosorbent assay ELISA measured Annexin II, AFP-L3, and AFP.
RESULTS: Annexin II was a biomarker with a significant difference between the LC and early HCC groups. TGF-β1 mRNA showed a significant difference when the LC group was compared to the control group and the late HCC group.
CONCLUSION: Annexin II has better sensitivity and specificity for early HCC detection than AFP, and TGF-β1 mRNA can be used for the assessment of the degree of HCC, and TGF-1 signaling inhibitors may be a possible new treatment choice for HCC.

La relation entre la formation en entrepreneuriat et l’intention entrepreneuriale dans l’enseignement supérieur au Maroc : le cas de l’Université Cadi Ayyad
Authors: Ben Massou Si Mohamed
Published: February 2023

La formation entrepreneuriale donne aux étudiants les compétences nécessaires pour gérer les défis inhérents à l'activité entrepreneuriale et exploiter les opportunités du marché. L'attention croissante portée à la formation entrepreneuriale a suscité des débats sur la question de savoir si cette formation dispensée dans les universités peut affecter positivement l’intention entrepreneuriale des étudiants. En s’inspirant de la théorie du comportement planifié développée par Ajzen, nous avons essayé de comprendre, par le biais d’une méthodologie quantitative et une démarche hypothético-déductive, comment la formation entrepreneuriale, les normes subjectives, les attitudes et le contrôle entrepreneurial perçu pourraient exercer une influence significative sur l'intention d'entreprendre chez les étudiants marocains poursuivant leurs études en Master 2 dans des écoles de commerce. L’application de la TPB (Theory of Planned Behavior) pour la première fois dans le contexte marocain, nous a permis d’enrichir les connaissances sur le sujet et de confirmer les résultats déjà publiés auparavant avec quelques particularités
Entre surveillance disproportionnée et inaction à l’égard d’élèves issus de l’immigration considérés à besoins éducatifs particuliers : une recherche ethnographique
Authors: Borri-Anadon Corina , Collins Tya
Published: February 2023

Bien que le discours inclusif soit de plus en plus présent dans les politiques éducatives québécoises, plusieurs enjeux traversent les interventions privilégiées à l’égard des élèves. Dans le cas des élèves issus de l’immigration, il s’agit notamment de la suridentification de certains sous-groupes d’élèves dans la population de l’adaptation scolaire et des risques d’exclusion associés à des interventions éducatives développées justement dans un souci d’équité. À partir d’une perspective interactionniste et d’une démarche ethnographique, cette contribution présente une typologie des interventions privilégiées par les intervenants scolaires à l’égard de quatre élèves issus de l’immigration fréquentant deux écoles primaires montréalaises. Par la suite, les négociations à l’œuvre entre acteurs scolaires quant aux interventions à mettre en place auprès de ces élèves seront discutées.
Les coulisses d’un travail en réseau : de la collaboration entre chercheurs sur la collaboration à visée inclusive

Cet article retrace les processus de co-construction de savoirs entre chercheurs intéressés au développement d’une visée inclusive au sein des écoles, depuis le tissage de réseaux internationaux au sein de la francophonie, jusqu’à l’aboutissement d’une publication collective réunissant 15 autrices et auteurs de trois continents, en passant par l’organisation d’un symposium virtuel en temps de pandémie. Une perspective interculturelle – qui ne se limite pas à la dimension internationale, mais s’adresse à toute rencontre entre différents systèmes de représentations – vient éclairer les liens entre le développement d’un leadership partagé, la négociation de collaborations interprofessionnelles, et l’organisation du travail, concernant aussi bien les acteurs et actrices de l’école, que les relations entre chercheuses et chercheurs.
Y a-t-il un bon usage du malentendu ?

Un référent islamique illégitime. La disqualification des jeunes musulmans au sein de l’espace associatif des héritiers de l’immigration
Authors: Nasri Foued
Published: February 2023

Cet article propose une sociogenèse des registres de disqualification des associations musulmanes au sein de l'espace associatif « jeune immigré » de l'agglomération lyonnaise durant les années 1990. Il s'appuie sur une enquête par entretiens, le dépouillement d'archives publiques et privées, et l'analyse de la presse associative, locale et nationale. Dans la continuité d'une approche en termes d'espace des mouvements sociaux, l'article situe la disqualification des engagements musulmans au sein des concurrences qui régissent l'espace associatif des héritiers de l'immigration entre les pôles « jeune immigré » et « jeune musulman », incarnés respectivement par les Jeunes Arabes de Lyon et banlieue (JALB) et l'Union des jeunes musulmans (UJM). Il décrit d'abord les usages des référents « arabe » et « musulman » en comparant les trajectoires biographiques et les carrières militantes des membres des JALB et de l'UJM et revient sur la réception contrastée de ces référents par le secteur pro-immigré et les institutions locales. Il explore ensuite les discours critiques vis-à-vis des usages militants du référentiel islamique et montre la façon dont les JALB se font progressivement les relais d'un discours discréditant à l'égard des acteurs musulmans, dans un contexte d'exacerbation des concurrences associatives et de paniques morales autour de l'islam. Ce faisant, il met en lumière la façon dont la disqualification des engagements musulmans se déploie comme un processus relationnel, évolutif et multisitué.
Lutter contre l’islamophobie ? Diversités tactiques, encadrement institutionnel et démobilisation du militantisme musulman à l’échelle locale
Authors: Talpin Julien

Comprendre la relative rareté des mobilisations contre l’islamophobie requiert d’aller au-delà d’une analyse d’une structure des opportunités politiques défavorable et de saisir à un niveau microsociologique le travail de mobilisation d’acteurs intermédiaires qui cherchent à convertir certains sentiments d’injustice en action collective. Cet article propose une telle investigation à partir d’une enquête localisée dans la ville de Roubaix et le suivi ethnographique de deux acteurs collectifs centraux : les lieux de culte et les associations qui luttent contre la stigmatisation des musulmans. Pour des raisons opposées – la reconnaissance institutionnelle dans un cas, la disqualification dans l’autre – ces acteurs ne parviennent pas ou plus à se constituer en opérateurs efficaces de mobilisation contre l’islamophobie. Alors que les mosquées roubaisiennes se sont fédérées en réaction à une controverse jugée islamophobe, elles ont noué des relations harmonieuses avec les pouvoirs publics – de droite comme de gauche – permettant la construction de plusieurs édifices d’ampleur et une reconnaissance de leur place dans la ville, mais les éloignant de toute logique contestataire. Les associations plus militantes en revanche, si elles ont un temps bénéficié de financements publics, ont vite été attaquées pour leur « communautarisme » supposé, les controverses successives contribuant à leur marginalisation. Les trajectoires de ces collectifs permettent de comprendre la démobilisation constatée sur le terrain en dépit d’une politisation diffuse liée à la stigmatisation croissante des musulmans.
Reconfigurations militantes et processus de dépolitisation au sein des ONG humanitaires islamiques françaises
Authors: Faure Lucas
Published: February 2023

Cet article propose une sociologie politique des responsables d’organisations humanitaires islamiques, en se focalisant sur les processus de dépolitisation affectant leurs engagements religieux. L’analyse s’appuie principalement sur des données ethnographiques récoltées en tant que bénévole au sein de plusieurs ONG françaises de 2017 à 2021. L’hypothèse est que l’engagement humanitaire suit des dynamiques différenciées de dépolitisation selon la génération militante : tandis que les fondateurs du Secours islamique France optent pour une relégation du religieux dans la sphère privée, les nouveaux acteurs de l’humanitaire musulman mettent en avant une technicisation de leurs compétences militantes. Si les responsables des structures étudiées partagent certaines caractéristiques sociales facilitant leur entrée en humanitaire, leurs engagements se font à des moments différents de leur carrière militante. Surtout, ces deux modalités de dépolitisation se comprennent de manière relationnelle, les circulations entre associations renforçant l’apprentissage itératif des contraintes politiques.
Precise asymptotics for complete integral convergence in the law of the logarithm under the sub-linear expectations
Authors: Huang Lizhen , Wu Qunying
Published: February 2023

The aim of this paper is to study and establish precise asymptotics for complete integral convergence in the law of the logarithm under the sub-linear expectation space. The methods and tools in this paper are different from those used to study precise asymptotics theorems in probability space. We extend precise asymptotics for complete integral convergence from the classical probability space to sub-linear expectation space. Our results generalize corresponding results obtained by Fu and Yang[13]. We further extend the limit theorems in classical probability space.
Stability analysis of multi-point boundary conditions for fractional differential equation with non-instantaneous integral impulse

Published: February 2023

This paper considers the stability of a fractional differential equation with multi-point boundary conditions and non-instantaneous integral impulse. Some sufficient conditions for the existence, uniqueness and at least one solution of the aforementioned equation are studied by using the Diaz-Margolis fixed point theorem. Secondly, the Ulam stability of the equation is also discussed. Lastly, we give one example to support our main results. It is worth pointing out that these two non-instantaneous integral impulse and multi-point boundary conditions factors are simultaneously considered in the fractional differential equations studied for the first time.
A multi-objective optimization framework with rule-based initialization for multi-stage missile target allocation
Authors: Zou Shiqi , Shi Xiaoping , Song Shenmin
Published: February 2023

This paper investigates a novel multi-objective optimization framework for the multi-stage missile target allocation (M-MTA) problem, which also widely exists in other real-world complex systems. Specifically, a constrained model of M-MTA is built with the trade-off between minimizing the survivability of targets and minimizing the cost consumption of missiles. Moreover, a multi-objective optimization algorithm (NSGA-MTA) is proposed for M-MTA, where the hybrid encoding mechanism establishes the expression of the model and algorithm. Furthermore, rule-based initialization is developed to enhance the quality and searchability of feasible solutions. An efficient non-dominated sorting method is introduced into the framework as an effective search strategy. Besides, the genetic operators with the greedy mechanism and random repair strategy are involved in handling the constraints with maintaining diversity. The results of numerical experiments demonstrate that NSGA-MTA performs better in diversity and convergence than the excellent current algorithms in metrics and Pareto front obtained in 15 scenarios. Taguchi method is also adopted to verify the contribution of proposed strategies, and the results show that these strategies are practical and promotive to performance improvement.
The effect of guardians' health literacy on the child's spending time at home: A cross-sectional study among Japanese schoolchildren
Authors: Sato Yuki , Suzuki Reiko , Shigihara Michiko , Suzuki Chieko
Published: February 2023

Background

The contents of children's daily activities and the amount of time spent on them has been directly linked to their health and development. Parental health behavior has also been considered a key factor, and the aim of this study was to determine the relationship between parent/guardian health literacy (HL) and their child's time spent at home by behavioral types. The study was conducted in elementary schools in Japan.

Method

The target subjects for this study were elementary schoolchildren (all grades, aged 6 to 12 years) and their parents/guardians, and almost 3000 schoolchildren and their parents/guardians in the Northern and Southern districts in Japan participated. The questionnaire for parents/guardians included amount of time spent per day on the seven major behavioral contents of their child's time at home, on weekdays and weekends, respectively, and a shortened five-item health literacy (HL) scale. Parent/guardian HL results were categorized into two groups (low HL group and high HL group), and we analyzed the association between the HL and child's time spent at home by behavioral contents.

Results

Children in the high HL parent/guardian group spent significantly less time watching TV and playing games than those in the low HL group, both on weekdays and weekends. Time spent playing outside on weekdays and on hobbies on weekdays and weekends was significantly longer for children in the high HL parent/guardian group than in the low HL group. Results of logistic regression analyses adjusted for confounders showed that higher parental/guardian HL reduced children's spending more than 30 minutes watching TV or playing games and increased children's spending more than 30 minutes on outside playing and doing hobbies.

Conclusions

Parental/guardian HL affected the child's time spent at home. The results could suggest that increasing parental/guardian HL has strong potential to improve children's major lifestyle behaviors．
Love Forever, Fear Never: Brazilian Musical Responses to a Political Coup
Authors: Whelden Schuyler
Published: February 2023

On May 12, 2016, the Brazilian Senate initiated impeachment proceedings of President Dilma Rousseff, installing Michel Temer as interim president. Temer’s agenda included Provsisional Measure No. 726, which shuttered Brazil’s Ministry of Culture, calamatious news for Brazilian culture makers, who relied on the ministry as a source of advocacy and financial support. In response, activists occupied state offices across the country in protest. At Palácio Gustavo Capanema, the Rio de Janeiro headquarters of the ministry, the occupation lasted more than 100 days. Culture makers from myriad disciplines and backgrounds showed support for the activists, with music and musicians playing a particularly important role in raising the profile and spirits of the occupation. The present article examines this moment through an analysis of a May 22 performance by composer Jards Macalé. Drawing on ethnographic work at the occupation and in-depth interviews with participants, it argues that musical performance, articulated through a politicized notion of love, served an important community-building function at these protests. It also contributes to debates by theorists such as Lauren Berlant and Sara Ahmed on the use of love to motivate political action. This language, while key to creating the possibility for identification, can be undercut by the lived exclusions of events like these when they do not include the presence of the people most affected by the policies being protested.

Introduction: Patient safety problems caused by students leads to different adverse event, hence clinical instructor plays a role in guiding them in the implementation of patient safety programs. Furthermore, the community of practice is considered to improve the role of clinical instructors in patient safety problems. This study is then conducted to measure the impact of community of practice toward the role of clinical instructors in patient safety problems.
Design and methods: This is a pre-experimental design for one group and a pre-post test design without a control group. In addition, the sample includes 36 prelicensure nursing students.
Result: The results showed that the score of clinical instructors’ role before and after intervention with community of practice implementation was 58 (34-67) and 79.33 with SD of 10,960, respectively, with a significant increase of 24.27. Also, the statistic analysis depicted that the role had a significant effect after implementation, with a p-value of < 0,000.
Conclusions: Based on the results, the community of practice had a significant impact in increasing the role of clinical instructors in the implementation of patient safety problems by prelicensure nursing students.
