É sabido que o Direito Administrativo não conta com um Código próprio, assim sendo, os Princípios servem para uniformizar, sistematizar e nortear todo o Direito Administrativo, atuando como fundamentos basilares normativos para as atividades da Administração Pública. O presente trabalho tem por objetivo apresentar os princípios que regem a Administração Pública, com enfoque no princípio da supremacia do interesse público sobre o interesse privado, tido como um supraprincípio do Direito Administrativo. Partindo desse contexto, a problemática desse artigo é: o princípio da supremacia do interesse público sobre o privado é suficiente para dar base jurídica às medidas restritivas impostas pela Administração Pública durante a pandemia de coronavírus no Brasil, considerando a relação vertical entre estado e indivíduo? Para tanto, utilizou-se metodologia de abordagem bibliográfica com movimento dedutivo, já que se partiu dos princípios em geral, chegando ao princípio em questão e, ao final, realizou-se um estudo de caso, relacionando o princípio com o primeiro decreto de contenção do coronavírus do Estado de São Paulo no contexto pandêmico. A análise mostra forte ligação do ato normativo que estabeleceu a quarentena em São Paulo com o princípio de supremacia do interesse público, inclusive pelo seu caráter de poder de polícia, e os resultados apontam que, apesar da controvérsia gerada pelas medidas de restrição, diante da complexidade das circunstâncias, naquele momento, elas foram ao encontro do interesse público.

Atıf Teorisi Bağlamında Başarısızlık Algısı ve Başarısızlığın Nedenleri Üzerine Bir Araştırma
Authors: Kahraman Ümmü Gülsüm , Oktar Ömer Faruk
Published: April 2024

Başarısızlık algısı, bireyin hangi sebepten ötürü başarısız olduğuna olan inançlarını yansıtmaktadır. Başarısızlık algısını anlamak, başarısızlığın nedenlerini ortadan kaldırmak için bir yol haritası sunma potansiyeline sahiptir. Bu noktadan hareketle çalışmanın amacı, üniversite öğrencilerinin başarısızlık algılarını anlamak ve başarısızlıklarına yükledikleri sebepleri keşfetmektir. Böylece başarısızlığın ortaya çıkmasına neden olan faktörler tespit edilerek, bu faktörlerin henüz başarısızlık ortaya çıkmadan, durdurulması şansı yakalanabilecektir. Atıf Teorisi, çalışma amacına ulaşmada yol gösterici kuram olmuştur. Atıf Teorisinin savlarının üniversite öğrencilerinin başarısızlık algılarının incelenmesi ile test edilmesine dayanan bu çalışmada, çalışmanın amacına uygun olarak nitel araştırma yöntemi ve betimsel fenomenoloji deseni tercih edilmiştir. Çalışma grubunun belirlenmesinde amaçlı örnekleme, veri toplama aracı olarak yarı yapılandırılmış mülakat yöntemi kullanılmıştır. Toplam 33 Yönetim Bilişim Sistemi lisans programı öğrencisi ile yüz yüze mülakat gerçekleştirilmiştir. Elde edilen veriler MAXQDA isimli program yardımı ile çözümlenmiştir. Araştırmada başarısızlığa yüklenen nedenler (i) ve başarısızlığın algılanma biçimleri (ii) olmak üzere iki tema keşfedilmiştir. Başarısızlığa yüklenen nedenler teması Atıf Teorisinin savına uygun olarak, dışsal ve içsel faktörler olmak üzere iki alt temadan oluşmaktadır. Başarısızlığın algılanma biçimleri teması ise başarısızlığa yüklenen faktörlerin bir yansıması olarak değerlendirilebilir. Bu yüzden başarısızlığın algılanma biçimleri teması dışsal atfetmenin sonucu ve içsel atfetmenin sonucu olarak isimlendirilmiştir. Başarısızlığın dışsal faktörlere yüklenmesi durumunda mutsuzluk ve kızgınlık/öfke duyguları yoğun olarak yaşanırken; başarısızlığın içsel faktörlere yüklenmesi durumunda hayıflanma ve eksiklik duyguları ön plana çıkmaktadır.

Authors: Jaigirder Tasmia , Ali Md. Moktar
Published: April 2024

Brick-and-Click organizations (Brick and Click Organizations) have emerged as a new type of business that aims to provide consumers with a seamless experience while purchasing products online. This study seeks to identify and understand the challenges that traditional businesses face when attempting to launch online sales services. The study employs a descriptive research design to address the research issues. Semi-structured interviews were conducted with key- decision-makers in such enterprises to get qualitative insights into the challenges faced by the businesses. This study's target population consists of Bangladeshi brick and click businesses. Online data were collected from a total of 1,036 respondents. The data were analyzed using descriptive statistics. The findings suggest that, businesses face a variety of online sales obstacles. Respondents from businesses indicate that their online sales difficulties were influenced by the product or service they sell and their interactions with customers, including their age, gender, and nature. Customers' distraction during online shopping is a common issue for click-only businesses. According to this study, however, brick- and-click retailers perceived it as a moderate challenge. The classic retail challenges of building personal relationships and providing a tactile product experience are not as daunting for brick and click businesses as they are for online-only businesses. By taking a proactive approach to the issues identified in this study, brick-and click businesses can not only overcome the immediate challenges but also position themselves favorably for future growth and success in the digital marketplace.

This research focused on identifying various types of faults occurring on 330kV transmission lines through the use of artificial neural networks (ANN). A MATLAB model for the Gwagwalada-Katampe 330kV transmission line in Nigeria was implemented to generate fault datasets. Voltage and current fault parameters were utilized to train and simulate the ANN network architecture selected for each stage of fault detection. Four types of faults were considered, along with a fifth condition representing no fault. The results illustrated the success of the developed model in identifying various fault conditions and system parameters on the Gwagwalada-Katampe 330kV transmission line, modelled using MATLAB Simulink.

India, the world's second-most populous country, boasts a significant youth demographic. In contemporary times, young individuals exhibit a penchant for motorcycles, often prioritizing style over safety by neglecting to wear helmets. Consequently, motorcycle accidents have seen a steady rise, resulting in fatalities predominantly attributed to head injuries. However, the adoption of helmets could mitigate such risks and prevent tragic outcomes. Furthermore, instances of driving under the influence have surged, contributing to accidents and fatalities owing to reckless behavior. In case of hit and run it is becoming some difficult to identify the vehicle. So, there is a need of identify the vehicle which hit the backside. These unfortunate occurrences have spurred the development of a technologically advanced solution: a safe drive headgear system. This innovative device aims to curb accidents and minimize fatalities by incorporating key features. For instance, the motorcycle only initiates upon the rider donning a helmet. Additionally, in cases of alcohol intoxication, the ignition system automatically disengages. By using ESP 32 camera and IR sensor we can identify the vehicle in hit and run case. Moreover, in the event of an accident, the integrated GSM modem swiftly dispatches distress messages to pre-registered contacts via a SIM card.

Noise characterization for pulsar-timing applications accounts for interstellar dispersion by assuming a known frequency dependence of the delay it introduces in the times of arrival (TOAs). However, calculations of this delay suffer from misestimations due to other chromatic effects in the observations. The precision in modeling dispersion is dependent on the observed bandwidth. In this work, we calculate the offsets in infinite-frequency TOAs due to misestimations in the modeling of dispersion when using varying bandwidths at the Green Bank Telescope. We use a set of broadband observations of PSR J1643−1224, a pulsar with unusual chromatic timing behavior. We artificially restricted these observations to a narrowband frequency range, then used both the broad- and narrowband data sets to calculate residuals with a timing model that does not account for time variations in the dispersion. By fitting the resulting residuals to a dispersion model and comparing the fits, we quantify the error introduced in the timing parameters due to using a reduced frequency range. Moreover, by calculating the autocovariance function of the parameters, we obtained a characteristic timescale over which the dispersion misestimates are correlated. For PSR J1643−1224, which has one of the highest dispersion measures (DM) in the NANOGrav pulsar timing array, we find that the infinite-frequency TOAs suffer from a systematic offset of ∼22 μs due to incomplete frequency sampling, with correlations over about one month. For lower-DM pulsars, the offset is ∼7 μs. This error quantification can be used to provide more robust noise modeling in the NANOGrav data, thereby increasing the sensitivity and improving the parameter estimation in gravitational wave searches.
New Insights on the Accretion Properties of Class 0 Protostars from 2 μm Spectroscopy
Authors: Le Gouellec Valentin J. M. , Greene Thomas P. , Hillenbrand Lynne A. , Yates Zoe
Published: April 2024

Sun-like stars are thought to accrete most of their final mass during the protostellar phase, during which the stellar embryo is surrounded by an infalling dense envelope. We present an analysis of 26 K-band spectra of Class 0 protostars, which are the youngest protostars. Of these, 18 are new observations made with the Keck MOSFIRE instrument. H i Brγ, several H2, and CO Δv = 2 features are detected and analyzed. We detect Brγ emission in 62%, CO overtone emission in 50%, and H2 emission in 90% of sources. The H i and CO emission is associated with accretion, while the H2 lines are consistent with shock excitation indicating jets/outflows. Six objects exhibit photospheric absorption features, with almost no outflow activity and no detection of the accretion-related Brγ emission line. Comparing these results with an archival sample of Class I K-band spectra, we find that the CO and Brγ emission lines are systematically more luminous in Class 0s, suggesting that the accretion is on average more vigorous in the Class 0 phase. Typically associated with the heated inner accretion disk, the much higher detection rate of CO overtone emission in Class 0s indicates also that episodes of high accretion activity are more frequent in Class 0 systems. The kinematics of the Class 0 CO overtone emission suggest either an accretion-heated inner disk or material directly infalling onto the central region. This could point toward an accretion mechanism of different nature in Class 0 systems than the typical picture of magnetospheric accretion.
Constraints on UHECR Sources and Extragalactic Magnetic Fields from Directional Anisotropies
Authors: Bister Teresa , Farrar Glennys R.
Published: April 2024

A dipole anisotropy in ultra–high-energy cosmic ray (UHECR) arrival directions, of extragalactic origin, is now firmly established at energies E > 8 EeV. Furthermore, the UHECR angular power spectrum shows no power at smaller angular scales than the dipole, apart from hints of possible individual hot or warm spots for energy thresholds ≳40 EeV. Here we exploit the magnitude of the dipole and the limits on smaller-scale anisotropies to place constraints on two quantities: the extragalactic magnetic field (EGMF) and the number density of UHECR sources or the volumetric event rate if UHECR sources are transient. We also vary the bias between the extragalactic matter and the UHECR source densities, reflecting whether UHECR sources are preferentially found in over- or underdense regions, and find that little or no bias is favored. We follow Ding et al. (2021) in using the CosmicFlows-2 density distribution of the local universe as our baseline distribution of UHECR sources, but we improve and extend that work by employing an accurate and self-consistent treatment of interactions and energy losses during propagation. Deflections in the Galactic magnetic field are treated using either the full JF12 magnetic field model, with both random and coherent components, or just the coherent part, to bracket the impact of the GMF on the dipole anisotropy. This large-scale structure model gives good agreement with both the direction and magnitude of the measured dipole anisotropy and forms the basis for simulations of discrete sources and the inclusion of EGMF effects.

Published: April 2024

Molecular emission is used to investigate both the physical and chemical properties of protoplanetary disks. Therefore, to derive disk properties accurately, we need a thorough understanding of the behavior of the molecular probes upon which we rely. Here we investigate how the molecular line emission of N2H+, HCO+, HCN, and C18O compare to other measured quantities in a set of 20 protoplanetary disks. Overall, we find positive correlations between multiple line fluxes and the disk dust mass and radius. We also generally find strong positive correlations between the line fluxes of different molecular species. However, some disks do show noticeable differences in the relative fluxes of N2H+, HCO+, HCN, and C18O. These differences occur even within a single star-forming region. This results in a potentially large range of different disk masses and chemical compositions for systems of similar age and birth environment. While we make preliminary comparisons of molecular fluxes across different star-forming regions, more complete and uniform samples are needed in the future to search for trends with birth environment or age.
ROME. IV. An Arecibo Search for Substellar Magnetospheric Radio Emissions in Purported Exoplanet-hosting Systems at 5 GHz
Authors: Route Matthew
Published: April 2024

Plasma flow–obstacle interactions, such as those between an exoplanet’s magnetosphere and the host star’s stellar wind, may lead to detectable radio emissions. Despite many attempts to detect magnetospheric (auroral) radio emissions from exoplanets, a reproducible, unambiguous detection remains elusive. This fourth paper of the Radio Observations of Magnetized Exoplanets (ROME) series presents the results of a targeted radio survey of nine nearby systems that host exoplanet, brown dwarf, or low-mass-stellar companions conducted with the Arecibo radio telescope at ∼5 GHz. This search for magnetospheric radio emissions has the greatest sensitivity (∼1 mJy during <1 s integration times) and collected full Stokes parameters over the largest simultaneous bandpass of any survey to date. It is also the first survey to search for radio emission from brown dwarfs of spectral class Y, which may illuminate open questions regarding their magnetism, interior and atmospheric structure, and formation histories. No magnetospheric radio emissions from substellar companions were detected. These results are examined within the context of recent theoretical work on plasma flow–obstacle interactions, and radio emissions observed from the solar system planets and ultracool dwarfs.

We present a new sample of 158 galaxies at redshift z > 7.5 selected from deep James Webb Space Telescope (JWST) NIRCam imaging of five widely separated sight lines in the CANUCS survey. Two-thirds of the pointings and 80% of the galaxies are covered by 12–14 NIRCam filters, including seven to nine medium bands, providing accurate photometric redshifts and robustness against low-redshift interlopers. A sample of 28 galaxies at z > 7.5 with spectroscopic redshifts shows a low systematic offset and scatter in the difference between photometric and spectroscopic redshifts. We derive the galaxy UV luminosity function at redshifts 8–12, finding a slightly higher normalization than previously seen with the Hubble Space Telescope at redshifts 8–10. We observe a steeper decline in the galaxy space density from z = 8 to 12 than found by most JWST Cycle 1 studies. In particular, we find only eight galaxies at z > 10 and none at z > 12.5, with no z > 10 galaxies brighter than F277W AB = 28 or M
UV = −20 in our unmasked, delensed survey area of 53.4 arcmin2. We attribute the lack of bright z > 10 galaxies in CANUCS compared to GLASS and CEERS to intrinsic variance in the galaxy density along different sight lines. The evolution in the CANUCS luminosity function between z = 8 and 12 is comparable to that predicted by simulations that assume a standard star formation efficiency without invoking any special adjustments.
Theoretical Analysis of the RX J0209.6−7427 X-Ray Spectrum during a Giant Outburst
Authors: West Brent F. , Becker Peter A. , Vasilopoulos Georgios
Published: April 2024

We model the spectral formation occurring in the binary X-ray pulsar (XRP) RX J0209.6−7427 during the 2019 super-Eddington outburst. Using a theoretical model previously developed by the authors, we are able to produce spectra that closely resemble the phase-averaged X-ray spectra observed using the Nuclear Spectroscopic Telescope Array and Insight-HXMT during low- and high-luminosity states of the outburst, respectively. The theoretical model simulates the accretion of fully ionized gas in a dipole magnetic field and includes a complete description of the radiation hydrodynamics, matter distribution, and spectral formation. Type II X-ray outbursts provide an opportunity to study accretion over a large range of luminosities for the same neutron star. The analysis performed here represents the first time both the outburst low and high states of an accretion-powered XRP are modeled using a physics-based model rather than standard phenomenological fitting with arbitrary mathematical functions. We find that the outer polar cap radius remains constant and the column is more fully filled with increasing luminosity, Comptonized bremsstrahlung dominates the formation of the phase-averaged X-ray spectrum, and a negative correlation exists between cyclotron centroid energy and luminosity, as expected. The super-Eddington nature of the outburst is rendered possible owing to the low scattering cross section for photons propagating parallel to the magnetic field. We also find that emission through the column top dominates in both the low and high states, implying that the pulse profiles should have a roughly sinusoidal shape, which agrees with observed properties of ultraluminous XRPs.

We have discovered the stellar counterpart to the ALFALFA Virgo 7 cloud complex, which has been thought to be optically dark and nearly star-free since its discovery in 2007. This ∼190 kpc long chain of enormous atomic gas clouds (M

Its faint, blue stellar counterpart, BC6, was identified in a visual search of archival optical and UV imaging. Follow-up observations with the Green Bank Telescope, Hobby–Eberly Telescope, and Hubble Space Telescope demonstrate that this faint counterpart is at the same velocity as the atomic gas, actively forming stars, and metal-rich (12 + (O/H) = 8.58 ± 0.25). We estimate its stellar mass to be only

, making it one of the most gas-rich stellar systems known. Aside from its extraordinary gas content, the properties of BC6 are entirely consistent with those of a recently identified class of young, low-mass, isolated, and star-forming clouds in Virgo that appear to have formed via extreme ram pressure stripping events. We expand the existing discussion of the origin of this structure and suggest NGC 4522 as a likely candidate; however, the current evidence is not fully consistent with any of our proposed progenitor galaxies. We anticipate that other “dark” gas clouds in Virgo may have similarly faint, star-forming counterparts. We aim to identify these through the help of a citizen science search of the entire cluster.

Published: April 2024

The current study presents an annotated checklist of the land snail species in the vicinity of the limestone hill of Gua (= cave) Rumbang, an outcrop located at the district of Padawan, Sarawak, Malaysian Borneo. The sampling was conducted at the surrounding areas and near the cave’s entrance. A total of 62 species, involving 19 families and 38 genera, were recorded. Comparison with previous surveys made in the Bau limestone hills revealed similarities with respect to the species-rich families Diplommatinidae and Cyclophoridae, and the genera Kaliella and Diplommatina, highlighting the regional consistency of the land snail diversity of the Bau-Padawan-Serian cluster. Possibly because of its smaller size, Gua Rumbang is home to two endemic species, while there are eight endemic species in the Bau limestone karsts. This suggests a potential for a significant species diversity within the areas of the limestone ranges that remain to be explored. Nonetheless, the occurrence of endemic species in Gua Rumbang highlights the need to conserve certain areas within the Padawan limestone range since hitherto no protected areas have been proposed in this region. In this checklist, a new species for science is also described, namely, Diplommatina rumbangensissp. nov.

L’impact des immigrés sur leur pays d’accueil
Authors: Cusset Pierre-Yves
Published: April 2024

Bien qu’il suscite toujours d’âpres controverses, l’impact économique de l’immigration est généralement considéré comme plutôt positif, tant pour les pays d’accueil que pour les pays d’origine. Mais qu’en est-il, plus généralement, des effets à long terme des immigrés et de leurs descendants sur les pays d’accueil ? Cette question plus complexe est rarement abordée, mais elle fait l’objet de travaux dont cet article de Pierre-Yves Cusset rend compte, à la lumière du livre de Garett Jones, The Culture Transplant : How Migrants Make the Economies They Move to a Lot like the Ones They Left. Plusieurs enseignements s’en dégagent. D’abord, les spécificités des immigrés, en termes de valeurs et normes sociales, ne disparaissent pas lorsqu’ils traversent la frontière ; de surcroît, ils les transmettent plus ou moins à leurs enfants et petits-enfants, mais les différences s’estompent au fil du temps. Ensuite, la force des liens humains prime sur celle des lieux et la diversité d’ascendance a des effets ambivalents : plutôt positifs sur la prospérité économique lorsqu’il s’agit de talents, d’expérience ou de compétence ; plutôt négatifs sur la confiance et la capacité à coopérer, notamment lorsqu’il s’agit d’attributs hérités (sexe, ethnicité…). Garett Jones conclut que l’apport de millions d’immigrés (il fait référence aux États-Unis), s’il peut être un avantage à court terme, présente aussi des dangers à long terme — en particulier en cas d’accueil massif d’immigrés provenant de pays à bas niveau de confiance et de civisme, et à haut niveau de corruption ou conflictualité. Mais il se garde bien de formuler un jugement péremptoire qui serait vrai quel que soit le pays d’origine ou d’accueil des immigrés. H.J.
L’image de « Montessori » : réceptions du montessorisme dans le champ de l’innovation pédagogique
Authors: Legavre Amélia
Published: April 2024

Cet article interroge l’image du montessorisme dans le champ de l’innovation pédagogique. Sur la base de discours collectés lors d’évènements portant sur ce thème et lors d’entretiens réalisés avec des éducateurs d’écoles privées dites « alternatives », il met en évidence la fonction d’étalon de l’approche Montessori, permettant aux acteurs de s’auto-situer dans l’espace des pédagogies alternatives. La mobilisation de références montessoriennes tient au fait que celles-ci offrent une caution « scientifique » aux pédagogies centrées sur l’enfant et à la critique corrélative de l’enseignement dit « traditionnel ». Néanmoins, les pratiques associées au montessorisme sont aussi mises à distance par certains acteurs, au travers de quatre types de critiques servant à s’en distinguer : l’élitisme ; l’individualisme ; l’immobilisme ; et l’instrumentalisme.
Mobiliser la pédagogie Montessori en écoles musulmanes : entre recherche de distinction et gestion du stigmate
Authors: Girin Diane-Sophie
Published: April 2024

Depuis une vingtaine d’années, on assiste au développement d’une offre d’enseignement privé musulman. Les écoles qui ont ouvert leurs portes font l’objet de nombreuses controverses, effaçant bien souvent la diversité interne de la catégorie. Dans cet article, nous proposons d’analyser de quelle manière certaines écoles musulmanes hors contrat de niveau élémentaire mobilisent la pédagogie Montessori, en particulier dans les cours de religion qu’elles dispensent à leurs élèves. Nous nous appuierons pour cela sur un travail d’enquête par entretiens et par observations auprès de onze établissements situés en France métropolitaine. Le recours à cette pédagogie répond à la fois à une volonté de distinction : ces écoles cherchent à affirmer leur spécificité vis-à-vis d’autres écoles musulmanes et des écoles coraniques. On peut également analyser ce recours aux méthodes montessoriennes comme une recherche de respectabilité pour échapper aux représentations disqualifiantes dont les écoles musulmanes font l’objet.

Le télétravail est devenu un phénomène planétaire depuis le début de la pandémie et semble s’installer durablement dans le monde du travail. Cette étude examine l’impact du télétravail sur la relation de l’individu au travail et les stratégies mises en œuvre pour y répondre. Eu égard à la nature peu connue du sujet et à la possibilité d’une construction théorique, on a utilisé une approche inductive du type SÉSAME. Précisément, 51 entretiens semi-directifs ont été réalisés en trois phases avec des intervenants en France, États-Unis, Allemagne et Royaume-Uni, entre 2020 et 2021. En outre, des données complémentaires ont été rassemblées grâce à des réunions d’équipes d’une durée de 52 heures sur des plates-formes variées, suivies de comptes-rendus et enregistrements de conversations. Les conclusions suggèrent que le travail à distance peut provoquer une menace considérable sur le psychisme de l’individu et modifier sa relation au travail. Trois types de menaces sur l’identité apparaissent : la reconstitution d’une identité limitée, le mélange d’identités et la perte de sens. Face à cette menace, les individus réagissent en protégeant ou/et en construisant leur identité propre comme réponse stratégique. En effet les personnes confrontées à une perte de sens, menace sur leur identité plus forte que celle de l’identité limitée ou du mélange d’identités, utiliseront très probablement une construction d’identité comme réponse stratégique. Les conclusions de la présente étude font progresser notre compréhension de l’identité dans le télétravail et la relation entre identité et espace. Cette investigation met aussi en lumière la dynamique d’un réseau identitaire dont les liens à l’identité et leur hiérarchie sont transformés. Des recherches à venir pourraient explorer les causes des menaces d’identité et la façon dont le travail à distance saurait créer de nouvelles opportunités d’identité.

Authors: Pramanik Sabyasachi
Published: April 2024

Innovative technologies including geothermal desalination, anaerobic digestion, microbial fuel cells, and internet of things integration may be able to aid with the combined challenges of wastewater treatment and energy sustainability. Anaerobic digestion converts organic waste into biogas, a renewable energy source that may be used to produce heat and electricity. Microbial fuel cells (MFCs) use the metabolic processes of microbes to convert organic materials into electricity, allowing for the simultaneous treatment of wastewater and the generation of renewable energy. Geothermal desalination reduces the need for fossil fuels and uses heat from geothermal sources to turn brackish or salty water into freshwater, which is less harmful to the environment. IoT connection allows geothermal desalination systems and bioenergy from wastewater processes to collect, monitor, control, and optimise data in real-time.
