Authors: Mamuriyah Nimatul , Lina Lina
Published: September 2024

PT Sat Nusapersada Tbk is a company engaged in the electronics industry and assembly. Sony Coin Battery is one of the departments that produce and package batteries which are then sold abroad. New materials or materials have their own barcode contained in each battery pack which needs to be scanned so that there are no errors in the delivery of goods from the store to the production department. So far, the existing database program is a database program with manual input without a barcode scanner. To meet the needs of scanning this new battery model, an excel database program was created with input in the form of a barcode scanner. To design a database store program equipped with a barcode scanner requires three stages. The three stages are data collection of the parts of the program, design of the program display form and coding design according to the function of each part. The designed program consists of three important parts, namely Incoming, Production and Shipment. These three sections are recorded in the excel database according to the battery model being run. The way it works is to scan the barcode then the data that has been typed and the barcode number will automatically enter the database. From the test results of the program, it was found that the program error rate was 4%. However, this program can be implemented to meet existing needs.
Game changer: How Janus kinase inhibitors are reshaping the landscape of ulcerative colitis management
Authors: Caballero-Mateos Antonio M , Cañadas-de la Fuente Guillermo Arturo
Published: September 2024

Recent advancements in the treatment landscape of ulcerative colitis (UC) have ushered in a new era of possibilities, particularly with the introduction of Janus kinase (JAK)-signal transducer and activator of transcription inhibitors. These novel agents offer a paradigm shift in UC management by targeting key signaling pathways involved in inflammatory processes. With approved JAK inhibitors (JAKis), such as tofacitinib, filgotinib, and upadacitinib, clinicians now have powerful tools to modulate immune responses and gene expression, potentially revolutionizing the treatment algorithm for UC. Clinical trials have demonstrated the efficacy of JAKis in inducing and maintaining remission, presenting viable options for patients who have failed conventional therapies. Real-world data support the use of JAKis not only as first-line treatments but also in subsequent lines of therapy, particularly in patients with aggressive disease phenotypes or refractory to biologic agents. The rapid onset of action and potency of JAKis have broadened the possibilities in the management strategies of UC, offering timely relief for patients with active disease and facilitating personalized treatment approaches. Despite safety concerns, including cardiovascular risks and infections, ongoing research and post-marketing surveillance will continue to refine our understanding of the risk-benefit profile of JAKis in UC management.

Authors: Abdi Nanang , Saleh Moh.
Published: September 2024

The research began with the problem of the city/district minimum wage as a basis for calculating health insurance contributions, where there are still several regions that overlap with each other, where the minimum wage difference is large and there are still employers who have not registered workers in the health insurance program. The research method uses a normative juridical research type with a statutory approach and a case approach. The results of the discussion are that the system for calculating BPJS contributions according to the UMK is still regulated in Presidential Decree 59/2024, where there is potential for social inequality and efforts to resolve the calculation of health insurance contributions in the form of making a collective agreement between workers, employers and elements of trade unions regarding adjustments to the amount of wages linked to payment capacity. health insurance contributions.

Published: September 2024

This study presents the results of examining the geomorphological structure of the bottom of Lake Ladoga. The research materials were obtained through the interpretation of a complex seismoacoustic data collected over the past 30–40 years. A pronounced geomorphological zonation along the axis of the water body has been established. The relief of the northern deep-water part of the basin is represented by constructural-denudative and lake nepheloid genetic types. The central part of the lake is characterized by glacial and glaciofluvial reliefs formed during the Neva marginal stage of the Ostashkov glaciation deglaciation. The southern shallow waters are composed of accumulative glacial-lacustrine and abrasional lacustrine plains. Here, paleo-shorelines features, indicating a lower water level than the present, are most prominently expressed. Fluvial and fluvio-nepheloid relief types are distinguished separately, with their forms azonally located on the bottom surface. The obtained data allow for detailed paleogeographic reconstructions of the Lake Ladoga development during the Late and Post-glacial.

Late glacial sections of Kulikovo and Utinoe Boloto (Kaliningrad Oblast) were studied using litho- logical, geochronological, diatom, palynological, geochemical, chironomid and microbiomorph analyses. The stages of development of the palaeobasin, which existed within the limits of the modern coast of the south-eastern part of the Baltic Sea during the Bølling-Allerød period (14.3–13.4 ka), are described. A detailed characterisation of the Late Pleistocene biota of the Kulikovo palaeobasin was made, and more than 200 taxa of diatom algae were found. A reconstruction of local late glacial vegetation was carried out, and, in particular, the role of woody species in the composition of vegetation cover in the Bølling-Allerød interval was described based on a new source of information, microbiomorphic (phytolith) analysis data, and the results of detailed anthracological analysis of the sections.

Some results of the study of bottom sediments of Lake Pertozero (Onega Coast of the White Sea) are presented – section stratigraphy, loss on ignition, diatom and chironomid analyses. At the initial stage of its development, the lake basin was part of a periglacial basin. Since its isolation around 11000 years ago, the lake has experienced several changes in sedimentary conditions that have affected the amount of organic matter contained in the sediments. These changes are noted throughout the lake. Brackish-water diatom complexes were not noted in the Holocene sediments, which indicates that in this area the sea level did not rise above 11 m.

Published: September 2024

Este estudio, enmarcado en el Doctorado en Estudios Sociales de la Universidad Francisco José de Caldas, busca examinar la problematización en torno a las prácticas mediáticas de los nativos digitales, particularmente su relación con los teléfonos inteligentes y su impacto en la salud de los estudiantes de la Institución Universitaria  A partir de lo anterior, se aplicó un cuestionario en línea, a una muestra (n=98) de nativos digitales universitarios entre 18 y 25 años de edad. Este cuestionario digital incluyó preguntas tipo Likert y preguntas abiertas, además de dos grupos focales para profundizar en el tema.  Los resultados del estudio proporcionaron una perspectiva teórica y argumentativa, que sugiere que el interés en la adopción del teléfono inteligente como recurso tecnológico y la elevada exposición a él se enfoca en su capacidad como herramienta gratificante, tanto por su utilidad práctica como por el acceso a una amplia gama de información y contenidos. Los logros del trabajo muestran la fascinación que despiertan los teléfonos inteligentes en los nativos digitales, lo que los lleva a pasar más tiempo del deseado en las plataformas, en el entendido de que es un comportamiento que genera gratificación y como consecuencia, se crea un ciclo vicioso entre la exposición continua y las recompensas, afectando significativamente la salud física y mental. Se adelanta un acercamiento importante a la percepción de salud y estilos de vida saludable de los jóvenes nativos digitales, logrando observar que no son conscientes de la afectación del uso prolongado del teléfono inteligente en su salud ni de la influencia de factores externos como los influencer en sus decisiones en temas de salud. Este conocimiento ha facilitado la comprensión del impacto de la tecnología en la salud y ha visibilizado la necesidad de implementar estrategias que fomenten un uso más consciente y responsable de los dispositivos digitales, abriendo la posibilidad de construir un puente entre la era digital y la promoción de estilos de vida más saludables para la generación caracterizada por su estrecha relación con las nuevas tecnologías.

Published: September 2024

In this study, Canada's renewable energy potential under future climate scenarios is assessed through an ensemble approach based on the CMIP6 models. The research is focused on the evaluation of hydro, solar, and wind energy potential across different regions in Canada, by taking into account projected changes in surface runoff, solar radiation, and windspeed from 2020 to 2099 under SSP2-4.5 and SSP5-8.5 scenarios. The results indicate significant spatial and temporal variations in renewable energy resources, with a general decline in surface runoff, particularly in Western Canada, which poses challenges for local hydropower generation. Solar energy potential is expected to increase consistently across all regions, with the most significant increases in central and northern Canada. Wind energy shows relatively smaller changes, with a notable increase in Eastern Canada. This comprehensive assessment provides crucial insights for optimizing renewable energy development, and supports Canada’s plan to transform into a low-carbon economy.

Published: September 2024

Recently, a day passed without fire outbreaks in Ghana generated many discussions on rumours relating to politics, sabotage or religious differences among others, yet little is done to reduce this high incidence of fire outbreaks. One quandary identified is that, there is no uniform standard for building safety design, and ambiguous acceptance criteria used by building designers enthralling them to design what they think it is vital to them, hence, ignoring regulations and standards as their benchmark. The study adopted a quantitative descriptive approach, and questionnaires items tested by principal architects and chief service engineers, totalling one –hundred and thirty-four (134) of which 95 for architects and 39 for services engineers with good standing firms, belonging to registered professional bodies across the country. The sampling frame was deduced from the list of currently Registered Architectural Consultancy Firms with good standing in the building construction industries in Ghana and the list of Service Engineering firms in Ghana Association of Incorporated Engineers in two cities namely, Kumasi, and Accra in Ghana, due to its highly concentrated architectural and service engineering firms. Kish (1965) formula was used for calculating minimum sample size for the study. SPSS Version 21.6 package was used to produce the statistical analysis tools for the study. Descriptive statistics such as frequency and percentages were used to summarize the data gathered from respondents. However, the influential critical factors identified from the literature, regulations, and international standards codes are grouped under ten components as follows;- 1) Holistic Design variables, 2) Relevance design considerations variables, 3) Fire safety objectives variables, 4) Performance based code variables, 5) Fire detection, alarm systems and suppression systems variables, 6) Active Fire Protection variables, 7) Building Fire Safety consideration variables, 8) Fire Emergency Power Design variables, 9) Built-in’ Fire Protection or ‘Passive Fire Protection’ (PFP) variables, and 10) Fire risk activities variables. The results of this study would enable fire safety designers in Ghana to be successful in its quest to incorporate these identified influential factors in their designs. The study seeks to find out critical influential factors related to design of building fire safety that contribute to BSI’s in Ghana: purposeful of given initial screening evaluation for fire safety and health performance throughout the entire design process.

We report a free-floating planet (FFP) candidate identified from the analysis of the microlensing event KMT-2023-BLG-2669. The lensing light curve is characterized by a short duration (≲3 days) and a small amplitude (≲0.7 mag). From the analysis, we find an Einstein timescale of t
E ⋍ 0.33 days and an Einstein radius of θ
E ⋍ 4.41 μas. These measurements enable us to infer the lens mass as

, where π
rel is the relative lens–source parallax. The inference implies that the lens is a sub-Neptune- to Saturn-mass object, depending on its unknown distance. This is the ninth isolated planetary mass microlens with θ
E < 10 μas, which is a useful threshold for an FFP candidate. We conduct extensive searches for possible signals of a host star in the light curve, but find no strong evidence for the host. We investigate the possibility of using late-time high-resolution imaging to probe for possible hosts. In particular, we discuss the case of finite-source point-lens FFP candidates, for which it would be possible to search for very-wide-separation hosts immediately, although such searches are “high risk, high reward.”

We present a new analysis of Kepler-21, the brightest (V = 8.5) Kepler system with a known transiting exoplanet, Kepler-21 b. Kepler-21 b is a radius valley planet (R = 1.6 ± 0.2R
⊕) with an Earth-like composition (8.38 ± 1.62 g cm–3), though its mass and radius fall in the regime of possible “water worlds.” We utilize new Keck/High-Resolution Echelle Spectrometer and WIYN/NEID radial velocity (RV) data in conjunction with Kepler and Transiting Exoplanet Survey Satellite (TESS) photometry to perform a detailed study of activity mitigation between photometry and RVs. We additionally refine the system parameters, and we utilize Gaia astrometry to place constraints on a long-term RV trend. Our activity analysis affirms the quality of Kepler photometry for removing correlated noise from RVs, despite its temporal distance, though we reveal some cases where TESS may be superior. Using refined orbital parameters and updated composition curves, we rule out a water world scenario for Kepler-21 b, and we identify a long-period super-Jupiter planetary candidate, Kepler-21 (c).
Estimated Heating Rates Due to Cyclotron Damping of Ion-scale Waves Observed by the Parker Solar Probe
Authors: Shankarappa Niranjana , Klein Kristopher G. , Martinović Mihailo M. , Bowen Trevor A.
Published: September 2024

Circularly polarized waves consistent with parallel-propagating ion cyclotron waves (ICWs) and fast magnetosonic waves (FMWs) are often observed by the Parker Solar Probe (PSP) at ion kinetic scales. Such waves damp energy via cyclotron resonance, and cyclotron damping is expected to play a significant role in the enhanced, anisotropic heating of the solar wind observed in the inner heliosphere. We employ a linear plasma dispersion solver, PLUME, to evaluate the frequencies of ICWs and FMWs in the plasma rest frame and Doppler-shift them to the spacecraft frame, calculating their damping rates at frequencies where persistently high values of circular polarization are observed. We find that such ion-scale waves are observed during 20.37% of PSP Encounters 1 and 2 observations and their plasma frame frequencies are consistent with them being transient ICWs. We estimate significant ICW dissipation onto protons, consistent with previous empirical estimates for the total turbulent damping rates, indicating that ICW dissipation could account for the observed enhancements in the proton temperature and its anisotropy with respect to the mean magnetic field.
Statistics and Habitability of F-type Star–Planet Systems
Authors: Patel Shaan D. , Cuntz Manfred , Weinberg Nevin N.
Published: September 2024

F-type star–planet systems represent an intriguing case for habitability studies. Although F-type stars spend considerably less time on the main sequence (MS) than G-, K-, and M-type stars, they still offer a unique set of features, allowing for the principal possibility of exolife. Examples of these features include the increased widths of stellar habitable zones as well as the presence of enhanced UV flux, which in moderation may have added to the origin of life in the Universe. In this study, we pursue a detailed statistical analysis of the currently known planet-hosting F-type stars by making use of the NASA Exoplanet Archive. After disregarding systems with little or no information on the planet(s), we identify 206 systems of interest. We also evaluate whether the stars are on the MS based on various criteria. In one approach, we use the stellar evolution code MESA. Depending on the adopted criterion, about 60–80 stars have been identified as MS stars. In 18 systems, the planet spends at least part of its orbit within the stellar habitable zone. In one case, i.e., HD 111998, known as 38 Vir, the planet is situated in the habitable zone at all times. Our work may serve as a basis for future studies, including studies on the existence of Earth-mass planets in F-type systems, as well as investigations of possibly habitable exomoons hosted by exo-Jupiters, as the lowest-mass habitable zone planet currently identified has a mass estimate of 143 Earth masses.
Neglected Silicon Dioxide Polymorphs as Clouds in Substellar Atmospheres
Authors: Moran Sarah E. , Marley Mark S. , Crossley Samuel D.
Published: September 2024

Direct mid-infrared signatures of silicate clouds in substellar atmospheres were first detected in Spitzer observations of brown dwarfs, although their existence was previously inferred from near-infrared spectra. With JWST’s Mid-Infrared Instrument, we can now more deeply probe silicate features from 8 to 10 μm, exploring specific particle composition, size, and structure. Recent characterization efforts have led to the identification of silica (silicon dioxide, SiO2) cloud features in brown dwarfs and giant exoplanets. Previous modeling, motivated by chemical equilibrium, has primarily focused on magnesium silicates (forsterite, enstatite), crystalline quartz, and amorphous silica to match observations. Here, we explore the previously neglected possibility that other crystalline structures of silica, i.e., polymorphs, may be more likely to form at the pressure and temperature conditions of substellar upper atmospheres. We evaluate JWST's diagnostic potential for these polymorphs and find that existing published transmission data are only able to conclusively distinguish tridymite, but future higher signal-to-noise ratio transmission observations, directly imaged planet observations, and brown dwarf observations may be able to disentangle all four of the silica polymorphs. We ultimately propose that accounting for the distinct opacities arising from the possible crystalline structure of cloud materials may act as a powerful, observable diagnostic tracer of atmospheric conditions, where particle crystallinity records the history of the atmospheric regions through which clouds formed and evolved. Finally, we highlight that high-fidelity, accurate laboratory measurements of silica polymorphs are critically needed to draw meaningful conclusions about the identities and structures of clouds in substellar atmospheres.

Published: September 2024

We explore the 511 keV emission associated with sub-GeV dark matter (DM) particles that can produce electron–positron pairs and form positronium after thermalizing. We use ∼16 yr of data from the Spectrometer on INTEGRAL to constrain DM properties, including the full positron propagation and losses, and the suppression of free electron density away from the Galactic plane. We show that the predicted longitude and latitude profiles vary significantly for different DM masses, unlike previous assumptions, and obtain the strongest limits on sub-GeV DM (from the MeV to a few GeV) so far, excluding cross sections down to 〈σ

Published: September 2024

Biodiversity data platforms including databases, websites and data repositories underpin conservation efforts by collecting spatiotemporal data of discovered native and alien species and maps of their distributions. Chalcid wasps (Hymenoptera, Chalcidoidea) are one of the most diverse insect groups estimated to include half a million species. Being mostly parasitoids of other arthropods, they have been successfully used as biological control agents against serious agricultural pests worldwide. In Cyprus, only 124 species of chalcid wasps have been recorded, with 53 species being alien to the island. Their true biodiversity is predicted to be much larger because the island is both under-sampled and under-researched. A number of biodiversity data platforms focusing on the biodiversity of Cyprus are currently online; however, an online platform dedicated on the chalcid wasps of Cyprus is lacking. In the framework of the Darwin Plus Fellowship (DPLUS202) “Species richness and biological invasions of Chalcid wasps in Akrotiri Peninsula”, the “Chalcid wasps of Cyprus” website (https://sites.google.com/view/chalcidwaspscyprus) is presented. This online, dynamic database aims to: (1) raise public awareness regarding a rather neglected and yet ecologically important insect group, (2) provide data on the morphology, ecology and biodiversity of Chalcidoidea on Cyprus, as well as (3) promote conservation needs by setting a baseline for the future assessment of both native and alien chalcid wasp species. This online platform will be regularly revised in order to provide an up-to-date, user-friendly digital environment to the scientific community, policy-makers and citizens.
Two new species of Karschia Walter, 1889 from Xizang, China (Solifugae, Karschiidae)
Authors: Fan Wenlong , Zhang Chao , Zhang Feng
Published: September 2024

Solifugae, commonly known as camel spiders, sun spiders or wind scorpions, is a relatively understudied order of predominantly nocturnal, cursorial and predatory arachnids, characterised by their formidable two-segmented chelicerae, voracious appetite and impressive speed. It is one of the meso-diverse arachnid orders, comprising 15 families, 144 genera, over 1200 described species and five monotypic fossil genera. Karschia Walter, 1889 is a small genus within the solifugid family Karschiidae, which, until now, had contained 32 species distributed in North Africa, Middle East and Central Asia, with 12 of these described from western regions of China.

Two new species of the genus Karschia Walter, 1889 are described from Xizang, China: Karschia (Karschia) shannan sp. nov. and Karschia (Karschia) trisetalis sp. nov. Detailed morphological descriptions, photographs of the bodies and a distribution map of these two new species are provided.
La Turquie est-elle toujours dans le camp occidental ?
Authors: Balci Bayram
Published: September 2024

Membre de l’OTAN, la Turquie fut longtemps considérée comme proche de l’Occident. L’inspiration occidentale avait présidé à la fondation de la république par Mustafa Kemal Atatürk. Mais, depuis quelques années, les alliances se diversifient : rapprochement avec la Chine et la Russie, soutien de l’Azerbaïdjan contre l’Arménie… Or, dans le même temps, la Turquie soutient l’Ukraine et s’investit dans la médiation. Ces éléments dessinent le tableau d’une puissance moyenne qui, à travers une pluralité de relations, désire renforcer son autonomie.
Dialoguer avec les musulmans en France
Authors: Bour Jean-François
Published: September 2024

Le Service national pour les relations avec les musulmans de la Conférence des évêques de France existe depuis 1973. Les relations entre catholiques et musulmans sont passées du souci social pour les travailleurs immigrés au dialogue interreligieux. Celui-ci est rendu plus difficile par le durcissement de certaines communautés, les quêtes identitaires et la dérive terroriste au nom de l’islam. Du fait de l’importance croissante de cette religion en France et dans le monde, il importe de poursuivre un dialogue exigeant.
Propos introductifs
Authors: Aubry de Maromont Clotilde
Published: September 2024

Cette contribution vise à relier les errances méthodologiques de la recherche doctorale observées empiriquement en laboratoire à la structuration du champ juridique. Alors que les questions épistémologiques et méthodologiques n’ont jamais été aussi prégnantes dans les facultés de droit, l’étude se veut contribuer aux controverses sur la méthode par une observation en laboratoire, des retours d’expériences et des réflexions sur le savoir juridique. Observer et discuter la recherche doctorale « en train de se faire » permet de mettre à jour les enjeux institutionnels, les représentations et les clivages disciplinaires qui exposent les doctorants à l’errance, parfois excessive, de la thèse. Pour présenter les différentes contributions du dossier, cette contribution part des principaux problèmes de méthode relevés par les jeunes chercheurs pour les expliquer par le champ tout en opérant des allers-retours avec la littérature scientifique.
Objets partagés, analyse juridique et interdisciplinarité
Authors: Champeil-Desplats Véronique
Published: September 2024

Cette contribution propose d’apporter des pistes de réponse à quelques questionnements récurrents que se posent les jeunes chercheurs. Il s’agit, tout d’abord, de problèmes méthodologiques ayant trait aux caractéristiques de l’objet d’étude et notamment son indétermination ; ensuite, de problèmes analytiques liés à la distinction entre la juridicité de l’objet d’étude et la juridicité des modes de questionnement sur celui-ci ; enfin, de problèmes méthodologiques relatifs à la pratique de l’interdisciplinarité (comment faire ?) qui débouchent sur des inquiétudes existentielles quant à la légitimité et à la réception institutionnelle des travaux de jeunes chercheurs s’engageant dans celle-ci.
Droit, sciences du droit et sociologie : cas français
Authors: Champeil-Desplats Véronique
Published: September 2024

Cette contribution propose d’illustrer la complexité des rapports entre le droit, science du droit et la sociologie en croisant deux textes qui ont, en France, chacun à leur époque, contribué à en structurer les représentations dominantes au sein de leur discipline respective. Du côté des juristes, il s’agit de l’article de Léon Duguit, « Le droit constitutionnel et la sociologie », publié à la Revue internationale de l’enseignement en 1889 ; du côté des sociologues, il s’agit de l’article, paru près de cent années plus tard, de Pierre Bourdieu, « La force du droit. Éléments pour une sociologie du champ juridique ». Il s’agit à partir de ces deux textes de relever les points communs mais aussi malentendus entre les champs disciplinaires pour entrevoir et suggérer des formes nouvelles d’entrecroisement.
La comparaison des droits (constitutionnels)
Authors: Ponthoreau Marie-Claire
Published: September 2024

Le comparatisme peut être conçu comme une passerelle entre les différentes sciences sociales. Cependant, le comparatiste doit reconnaître que le comparatisme n’est pas forcément synonyme d’interdisciplinarité car tout dépend de la conception du droit qu’il retient. La voie de l’interdisciplinarité n’est praticable qu’à la condition de concevoir le droit d’une manière qui échappe aux seules sources officielles du droit. Alors l’esprit d’enquête peut s’épanouir dans un effort de contextualisation du droit et une variation d’échelle sur son objet de recherche. Les sciences sociales peuvent néanmoins se retourner contre la comparaison des droits car si la pratique interdisciplinaire présente des intérêts, elle est aussi parsemée de chausse-trapes. Le défi est alors d’apprendre à composer avec les autres champs du savoir sans s’y engloutir. En effet, il ne s’agit nullement d’adopter le point de vue d’une autre science sociale, mais de prendre appui sur l’histoire ou un autre savoir pour éclairer, par exemple, la compréhension de la constitution.
Pour une intégration des sources audiovisuelles dans la recherche juridique
Authors: Ho Dinh Anne-Marie , Villegas Diana
Published: September 2024

Malgré la place de plus en plus importante accordée aux documents audiovisuels aux xx e  et xxi e  siècles, les sciences sociales ont conservé jusqu’à présent un lien privilégié et prédominant avec l’écrit. À cet égard, la science juridique ne fait pas figure d’exception. On constate en effet une marginalisation de leur usage dans la science du droit et dans la recherche juridique, en raison notamment d’une limitation des sources du droit et des méthodes de la dogmatique juridique, bien que l’on observe ces dernières années un intérêt grandissant des juristes pour l’approche Droit et Cinéma. Dans l’hypothèse d’un droit davantage contextualisé, l’exclusion des sources audiovisuelles semble en effet devoir être nécessairement dépassée. Elles constituent pour le chercheur des outils méthodologiques essentiels pour saisir le droit vécu par ses acteurs et les représentations à l’œuvre dans la société, et favorise également le dépassement des frontières disciplinaires.
Mathématiques et sciences juridiques
Authors: Viaut Laura
Published: September 2024

Probabilité et loi ne sont pas étrangères l’une à l’autre. Le concept de probabilité épistémique impose, en effet, de faire la différence entre ce qui cause l’apparition d’une chose et ce qui nous informe qu’elle est apparue. L’un des mathématiciens du siècle, Jacques Bernoulli, né à Bâle en 1654, a travaillé sur la probabilité empirique, laquelle prend comme base de réflexion des faits. Son traité posthume, consacré théorie de la probabilité et intitulé l’art de conjecturer , paraît en 1713, propose d’appliquer l’art de conjecturer à la vie civile, morale et politique. Ce fut là une grande originalité, laquelle mérite aujourd’hui toute l’attention de l’historien du droit.
Terre, air et eau : le droit pénal de l’environnement au milieu du gué
Authors: de Redon Louis
Published: September 2024

Le droit pénal de l’environnement souffre d’une profonde inefficacité et la protection par la police judiciaire des milieux physiques comme des espaces naturels apparaît comme insuffisante pour répondre aux enjeux de la transition écologique. Les raisons sont multiples. Parmi elles, le véritable maquis d’incriminations créées par le législateur sans véritable cohérence punissant (parfois) des atteintes mineures à l’environnement et fermant les yeux (souvent) sur des atteintes plus graves. Le tout sous la férule d’une police administrative qui décide seule des atteintes autorisées et des atteintes réprimées. Le dommage réel porté à l’environnement est ainsi rarement pris en considération. L’objet de cette étude est donc double : 1. établir un état des lieux quasi-exhaustif de la protection des milieux physiques et des espaces naturels par le droit pénal de l’environnement, et 2. évaluer la nécessité de créer, ou pas, un délit d’écocide dont le périmètre reste à déterminer.
La plainte administrative
Authors: Colin Frédéric
Published: September 2024

La « plainte » constitue un « angle mort » du droit administratif : elle est incontestablement utilisée, mais n’est pas encore définie. Si on ne peut la rattacher à une incrimination pénale, la plainte administrative entretient pourtant avec elle des points de convergence conceptuelle. Elle peut s’envisager aussi bien à l’encontre d’administrations de gestion, que de la juridiction administrative ou d’autorités administratives indépendantes, ou de personnes privées investies de mission de service public. La plainte est une saisine d’un organe administratif afin de dénoncer un acte ou un comportement d’une personne chargée d’une mission de service public ou sous le contrôle d’une administration publique, et susceptible de faire l’objet d’une sanction disciplinaire de nature administrative.
