A Multi-Grained Attention Residual Network for Image Classification
Authors: Xiaogang Wu , Tanprasert Thitipong
Published: June 2023

Attention mechanisms in deep learning can focus on critical features and ignore irrelevant details in the target task. This paper proposes a new multi-grained attention model (MGAN) to extract parts from images. The model includes a multi-grain spatial attention (MSA) mechanism and a multi-grain channel attention (MCA) mechanism. We use different convolutional branches and pooling layers to focus on the crucial information in the sample feature space and extract richer multi-grain features from the image. The model uses ResNet and Res2Net as the backbone networks to implement the image classification task. Experiments on the CIFAR10/100 and Mini-Imagenet datasets show that the proposed model MGAN can better focus on the critical information in the sample feature space, extract richer multi-grain features from the images, and significantly improve the image classification accuracy of the network.
Characterization of Wireless Multi-hop Paths with High Quality: Toward a Theoretical Framework
Authors: Nakano Keisuke , Sengoku Masakazu , Shinoda Shoji
Published: June 2023

In this paper, we consider the quality of communication paths in wireless multi-hop networks. A wireless multi-hop network consists of wireless nodes and wireless links. In this network, there usually exist various candidate paths to connect a source and a destination. We can evaluate the quality of each of the candidate paths by using a metric for link quality, and as a result, we can choose the path with the highest quality (best path). In this paper, we pay attention to characteristics of the best path, and consider how to theoretically characterize the best path and its quality because it is an important issue from the viewpoint of network design. We introduce some recent results on theoretical identification of the best path and theoretical formulas to evaluate the quality of the best path in wireless multi-hop networks with regular structure. We explain how the best path is identified using examples. We also introduce results on theoretical characterization of the best path in random wireless multi-hop networks. Finally, we describe some related issues.

Published: June 2023

Robust DC-DC converter which can covers extensive load changes and also input voltage changes with one controller is needed. The demand to suppressing output voltage changes becomes still severer. We proposed an approximate 2DOF digital controller which realizes the startup response and dynamic load response independently. The controller makes the control bandwidth wider, and at the same time makes a variation of the output voltage small at sudden changes of loads and input voltages. In this paper, a new approximate 2DOF digital control system with additional zeros is proposed. Using additinal zeros second-order differential transfer characteristics between equivalent disturbances and an output voltage are realized. Therefore the new controller makes variations of the output voltage smalerl at sudden changes of loads and input voltages. This controller is actually implemented on a DSP and is connected to a DC-DC converter. Experimental studies demonstrate that this type of digital controller can satisfy given severe specifications.
A Design Method for Robust Stabilizing Simple Multi-Period Repetitive Controllers for Time-Delay Plants
Authors: Yamada Kou , Ando Yoshinori , Hagiwara Takaaki , Kobayashi Masahiko , Sakanushi Tatsuya
Published: June 2023

A multi-period repetitive control system is a type of servomechanism for a periodic reference input. Even if a plant does not include time-delay, the transfer function from the periodic reference input to the output and that from the disturbance to the output of the multi-period repetitive control system generally have an in¯nite number of poles. When the transfer function from the periodic reference input to the output and that from the disturbance to the output have an in¯nite number of poles, it is difficult to settle the input-output characteristic and the disturbance attenuation characteristic of the multi-period repetitive control system. In order to specify the input-output characteristic and the disturbance attenuation characteristic easily, Yamada and Takenaga proposed the concept of simple multi-period repetitive control systems such that the controller works as a stabilizing multi-period repetitive controller and the transfer function from the periodic reference input to the output and that from the disturbance to the output have a ¯nite number of poles. However, the method by Yamada and Takenaga cannot be applied to time-delay plants with uncertainty. The purpose of this paper is to propose the concept of robust stabilizing simple multi-period repetitive controllers for time-delay plants with uncertainty and to clarify the parametrization of all robust stabilizing simple multi-period repetitive controllers for time-delay plants with uncertainty.
A Modified Edge Removal Stiener Tree Heuristic for Global Routing in VLSI Design
Authors: Terapasirdsin Apichat , Rotach William F. , Wattanapongsakorn Naruemon , Madden Patrick H.
Published: June 2023

Routing is a key stage for VLSI physical design. Steiner tree construction is a well studied topic in design automation. There have been a number of significant theoretical advances in the past few years. The focus of this paper is on combining the speed and solution quality of a high quality Steiner heuristic with the reality of modern routing. Practical designs contain routing congestion and blockages; routing is implemented across multiple layers. Each routing layer has preferred directions, and connecting vias have significant cost. In a modern design, many trees are in competition with each other for scarce routing resources. The objective is not to simply build trees with the lowest length; they must also be low cost. We present an approach that is as fast as spanning tree construction, while accurately modeling routing costs. Our work extends an earlier Steiner tree heuristic algorithm by adding the ability to minimize the routing congestion without altering the computational complexity of the underlying algorithm. We compare our CAST algorithm with the capacitated minimum spanning tree (CMST) and the ER algorithm finding that our approach offers impressive reduction in congestion cost in average about 23.1% and 63.4%, respectively.
Reduction of Torque Ripple in Direct Torque Control for Induction Motor Drives Using Decoupled Amplitude and Angle of Stator Flux Control
Authors: Kumsuwan Yuttana , Srirattanawichaikul Watcharin , Premrudeepreechacharn Suttichai
Published: June 2023

This paper proposes design and implementation of a direct torque controlled induction motor drive system. The method is based on decouple control of the amplitude and the angle of the stator flux reference for determining the reference stator voltage vector in generating the PWM output voltage for induction motors. The objective is to reduce electromagnetic torque ripple and stator flux droop which result in a decrease in current distortion at steady state. The proposed technique is based on the relationship between the instantaneous slip angular frequency and rotor angular frequency in adjustment of the stator °ux angle reference. The amplitude of the reference stator flux is always kept constant at rated value. The system has been implemented to verify its capability such as torque and stator °ux responses, stator phase current distortion both during dynamic and steady state with load variation, and low speed operation.

Published: June 2023

We examine the parameterization of all disturbance observers for time-delay plants. Disturbance observers have been used to estimate unknown disturbance in plants. There have been several works on design methods of disturbance observers for time delay plants but no published work on the parameterization of all disturbance observers for time-delay plants. We propose the parameterization of all disturbance observers for time-delay plants and that of all linear functional disturbance observers for time-delay plants.

Published: June 2023

A hard disk drive and a flash memory have become high capacity, so that we are now in the situation where a lot of TV programs can be recorded. However, while convenient, it is not easy to watch all the recorded programs in a limited time. Therefore, an efficient TV browsing application is needed. In this paper, we propose a key frame detection method for TV news program to allow a viewer to efficiently browse TV news programs and/or particular TV news topics. Instead of using features specific to certain news topics, our proposal is to extract important features which are common to news topics, and to generally detect the unique key frame which best represents each news topic. We show the validity of our proposed method by a simulation experiment.

Authors: Hagiwara Takaaki , Yamada Kou , Aoyama Satoshi , Hoang An Chinh
Published: June 2023

In this paper, we examine the parameterization of all plants stabilized by a proportional-derivative (PD) controller. A PD controller is a kind of Proportional- Integral-Derivative (PID) controllers. PID controller structure is the most widely used one in industrial applications. Recently, if stabilizing PID controllers for the plant exist, the parameterization of all stabilizing PID controllers has been considered. However, no paper examines the parameterization of all plants stabilized by a PID controller. In this paper, we clarify the parameterization of all plants stabilized by a PD controller. In addition, we present the parameterization of all stabilizing PD controllers for the plant stabilized by a PD controller.

Published: June 2023

The simple repetitive control system proposed by Yamada et al. is a type of servomechanism for the periodic reference input. That is, the simple repetitive control system follows the periodic reference input with small steady state error, even if a periodic disturbance or an uncertainty exists in the plant. In addition, simple repetitive control systems make transfer functions from the periodic reference input to the output and from the disturbance to the output have finite numbers of poles. In addition, Yamada et al. clarified the parameterization of all stabilizing simple repetitive controllers. Recently, the parameterization of all stabilizing simple repetitive controllers for time-delay plants was clarified by Yamada et al. However their method cannot be applied to multiple-input/multiple-output time-delay plants. In this paper, we propose the parameterization of all stabilizing simple repetitive controllers for multipleinput/ multiple-output time-delay plants.

Authors: Chaijarurnudomrung Koson , Areerak Kongpan , Areerak Kongpol , Kwannetr Umaporn
Published: June 2023

This paper presents a controller design for a threephase controlled rectifier using artificial intelligence techniques to regulate the DC-bus voltage. The averaging model of the power electronic system is used as an objective function instead of the model from software packages. The averaging model is derived from the DQ modeling approach in which the dynamics of the transmission line and power converter are taken into account for the controller design. The results show that the proposed method can efficiently obtain the best performance of the output waveform compared with the classical method. Moreover, this approach is convenient and flexible for electrical engineering to design the controller of power electronic systems with the best output performance.

Estimating the Harmonic Contributions of Utility and Costumer in a distorted power system
Authors: Ajami Ali , Bagheri Farzaneh
Published: June 2023

This paper presents an improved method for determining the contribution of harmonic distortion generated by utility and customer at the Point of Common Coupling (PCC) in a distorted power system. For this purpose, first the magnitude and phase of voltage and current at the PCC in each frequency are estimated by adaptive Kalman filter. Then the parameters of Thevenin equivalent circuits of load and utility sides are estimated using the recursive least squares technique based on singular value decomposition (SVD). Finally, the contribution of utility and customer in harmonic distortion of the 3-phase voltage waveforms has been calculated by three approaches. A case study has been made to verify the accuracy of the proposed method. Also, the presented method has been used in a 13-bus IEEE standard distribution system. Presented simulation results show that the proposed method can accurately determine the harmonic contributions of utility and customer for measurements made at the PCC.

Authors: Nagy Zoltán
Published: June 2023

Aim: The study briefly sums up the position of the designated non-financial businesses and professions (DNFBPs) within the anti-money laundering framework while describing the main risks associated with these type of service providers. The study covers the willingness of the DNFBPs to file suspicious activity reports (SARs) to the financial intelligence unit and tries to assess potential solutions to mitigate money-laundering related risks.Methodology: The study examines the relevant international literature, guidances, the legal acts of the European Union and Hungary. The study also uses statistical data available to the Hungarian Financial Intelligence Unit. The statistical data originating from the database of the Hungarian Financial Intelligence Unit are based on either data submitted by the obliged entities (e.g. electronic register of designated persons, submitted of SARs) or based on data recorded by the Hungarian Financial Intelligence Unit on the conducted procedures. The datasets are partially recorded automatically by the IT infrastructure and partially recorded manually. The manually recorded datasets are checked again to ensure accuracy of the data. Hence, the data originating from the database of the Hungarian Financial Intelligence Unit can be deemed reliable. The study uses descriptive statistical methodology.
Findings: It can be established that designated non-financial businesses and professions face considerable money laundering risk that causes a substantial vulnerability in the anti-money laundering framework not only in Hungary, but in the EU and worldwide. The deficiencies among others cause an exceptionally low willingness to submit suspicious activity reports. Recognizing the vulnerabilities, the relevant international organizations and the EU urges actions that lead to tighter supervision on non-financial businesses and professions and closer cooperation between the supervising authorities. These actions aim to reduce the money laundering risks posed by the sector.Value: The study examines several years’ statistical data and compares them to the actual trends prevalent in the field of non-financial businesses and professions and draws attention to a sector overlooked in the aspect of money laundering risks.

Aim: The aim of study is to outline the cornerstones of the (EU) 2018/1673 Directive on combating money laundering by criminal law and to show how a Member State, Germany, has fulfilled its legal harmonization obligation in the field of the criminal law regulation.Methodology: During the research, the relevant EU legislation was presented, and the German Criminal Code was analyzed in terms of the dogmatic analysis of the money laundering offence.Findings: Despite the regulations of the EU Directives, there are significant differences between national regulations. The Amendment of the Criminal Code in 2021 introduced a paradigm shift in the criminal law regulation of money laundering in Germany. It introduced the so-called "all crime" approach in connection with the predicate offences. It is also worth mentioning that the German Criminal Code makes specific provision for the criminalization of the predicate offence committed abroad.Value: Regarding the cross-border nature of money laundering, it may be useful for both legislators and practitioners to familiarize themselves with the legislation of other Member States. In Hungary, there has been no recent academic work on the German legislation in force.

Published: June 2023

Background: Myofascial pain syndrome (MPS) is the most common diagnosis in patient presenting with chronic nonspecific neck pain. It affects people’s work performance, productivity, and quality of life. To date, there is little research evaluating the effectiveness of non-invasive techniques, such as ISBT-Bowen Therapy in managing neck MPS.
Objectives: To investigate the effectiveness of Bowen therapy in managing myofascial pain syndrome with symptoms lasting for more than six weeks. The study will also examine the long-term effect of ISBT-Bowen Therapy on functional enhancement, quality of life, and physical and mental well-being.
Methods: This is a prospective, single-blinded randomized controlled trial (RCT). A total of 90 myofascial neck pain patients were recruited and randomized to receive 8 sessions of ISBT-Bowen Therapy over a 12-week period (n = 45) or to continue their usual conventional treatment (n  =  45). Pressure pain threshold (PPT), cervical range of motion (CROM), numerical rating pain scores, Neck Disability Index (NDI), SF-12 Health Survey (SF-12) Version 2, Generalized Anxiety Disorder 7-item (GAD7), and Patient Health Questionnaire (PHQ9) were measured at baseline, 12 weeks, and 24 weeks after baseline.
Results: When compared with the control group, PPT significantly increased after ISBT-Bowen Therapy at 12 and 24 weeks. CROM on flexion, lateral flexion, and rotation were greatly improved at 12 weeks after Bowen therapy, and maintained at 24 weeks, except left lateral flexion. NDI, GAD7, and PHQ9 were all reduced after Bowen Therapy at both 12 and 24 weeks. Both Physical and Mental Component Summary scores of SF-12 were improved after Bowen therapy at 12 and 24 weeks.
Conclusions: This study confirmed the efficacy of ISBT-Bowen Therapy for patients with MPS. It alleviates pain, improves functional outcomes, enhances quality of life, and relieves mood symptoms.

The Nature of LoBAL QSOs. II. HST/WFC3 Observations Reveal Host Galaxies Dominated by Mergers

Published: June 2023

Low-ionization broad absorption line QSOs (LoBALs) are suspected to be merging systems in which extreme, active galactic nucleus-driven outflows have been triggered. Whether or not LoBALs are uniquely associated with mergers, however, has yet to be established. To characterize the morphologies of LoBALs, we present the first high-resolution morphological analysis of a volume-limited sample of 22 Sloan Digital Sky Survey (SDSS)-selected LoBALs at 0.5 < z < 0.6 from Hubble Space Telescope Wide Field Camera 3 observations. Host galaxies are resolved in 86% of the systems in F125W, which is sensitive to old stellar populations, while only 18% are detected in F475W, which traces young, unobscured stellar populations. Signs of recent or ongoing tidal interaction are present in 45%–64% of the hosts, including double nuclei, tidal tails, bridges, plumes, shells, and extended debris. Ongoing interaction with a companion is apparent in 27%−41% of the LoBALs, with as much as 1/3 of the sample representing late-stage mergers at projected nuclear separations <10 kpc. Detailed surface brightness modeling indicates that 41% of the hosts are bulge dominated while only 18% are disks. We discuss trends in various properties as a function of merger stage and parametric morphology. Notably, mergers are associated with slower, dustier winds than those seen in undisturbed/unresolved hosts. Our results favor an evolutionary scenario in which quasar-level accretion during various merger stages is associated with the observed outflows in low-z LoBALs. We discuss differences between LoBALs and FeLoBALs and show that selection via the traditional balnicity index would have excluded all but one of the mergers.

Published: June 2023

Protostellar outflows are considered a signpost of star formation. These outflows can cause shocks in the molecular gas and are typically traced by the line wings of certain molecules. HNCO (4–3) has been regarded as a shock tracer because of the high abundance in shocked regions. Here we present the first imaging results of HNCO (4–3) line wings toward nine sources in a sample of 23 massive star-forming regions using the Instituto de Radioastronomía Milimétrica 30 m Telescope. We adopt the velocity range of the full width of HC3N (10–9) and H13CO+ (1–0) emissions as the central emission values, beyond which the emission from HNCO (4–3) is considered to be from line wings. The spatial distributions of the red and/or blue lobes of HNCO (4–3) emission nicely associate with those lobes of HCO+ (1–0) in most of the sources. High-intensity ratios of HNCO (4–3) to HCO+ (1–0) are obtained in the line wings. The derived column density ratios of HNCO to HCO+ are consistent with those previously observed toward massive star-forming regions. These results provide direct evidence that HNCO could trace outflow in massive star-forming regions. This work also implies that the formation of some HNCO molecules is related to shock, either on the grain surface or within the shocked gas.

How structures, e.g., magnetic loops, in the upper atmosphere, i.e., the transition region and corona, are heated and sustained is one of the major unresolved issues in solar and stellar physics. Various theoretical and observational studies on the heating of coronal loops have been undertaken. The heating of quiescent loops caused by eruptions, however, is rarely observed. In this study, employing data from the Solar Dynamics Observatory (SDO) and Solar Upper Transition Region Imager (SUTRI), we report the heating of quiescent loops associated with nearby eruptions. In active regions (ARs) 13092 and 13093, a long filament and a short filament, and their overlying loops, were observed on 2022 September 4. In AR 13093, a warm channel erupted toward the northeast, whose material moved along its axis toward the northwest under the long filament, turned to the west above the long filament, and divided into two branches falling to the solar surface. Subsequently, the short filament erupted toward the southeast. Associated with these two eruptions, the quiescent loops overlying the long filament appeared in SDO/Atmospheric Imaging Assembly (AIA) high-temperature images, indicating the heating of loops. During the heating, the signature of magnetic reconnection between loops is identified, including the inflowing motions of loops, and the formation of X-type structures and newly reconnected loops. The heated loops then cooled down. They appeared sequentially in AIA and SUTRI lower-temperature images. All the results suggest that the quiescent loops are heated by reconnection between loops caused by the nearby warm channel and filament eruptions.

Determining accurate effective temperatures of stars buried in the dust-obscured Galactic regions is extremely difficult from photometry. Fortunately, high-resolution infrared spectroscopy is a powerful tool for determining the temperatures of stars with no dependence on interstellar extinction. It has long been known that the depth ratios of temperature-sensitive and relatively insensitive spectral lines are excellent temperature indices. In this work, we provide the first extensive line depth ratio (LDR) method application in the infrared region that encompasses both the H and K bands (1.48 μm − 2.48 μm). We applied the LDR method to high-resolution (R ≃ 45,000) H- and K-band spectra of 110 stars obtained with the Immersion Grating Infrared Spectrograph. Our sample contained stars with 3200 < T
eff (K) < 5500, 0.20 ≤ log g < 4.6, and −1.5 < [M/H] < 0.5. The application of this method in the K band yielded 21 new LDR–T
eff relations. We also report five new LDR–T
eff relations found in the H-band region, augmenting the relations already published by other groups. The temperatures found from our calibrations provide reliable temperatures within ∼70 K accuracy compared to spectral T
eff values from the literature.
Surveying the Giant H ii Regions of the Milky Way with SOFIA: V. DR7 and K3-50

Published: June 2023

We present our fifth set of results from our mid-infrared imaging survey of Milky Way Giant H ii (GH ii) regions with our detailed analysis of DR7 and K3-50. We obtained 20/25 and 37 μm imaging maps of both regions using the FORCAST instrument on the Stratospheric Observatory For Infrared Astronomy. We investigate the multiscale properties of DR7 and K3-50 using our data in conjunction with previous multiwavelength observations. Near- to far-infrared spectral energy distributions of individual compact infrared sources were constructed and fitted with massive young stellar object (MYSO) models. We find eight out of the ten (80%) compact sources in K3-50 and three out of the four (75%) sources in DR7 are likely to be MYSOs. We derived luminosity-to-mass ratios of the extended radio subregions of DR7 and K3-50 to estimate their relative ages. The large spread in evolutionary state for the subregions in K3-50 likely indicates that the star-forming complex has undergone multiple star-forming events separated more widely in time, whereas the smaller spread in DR7 likely indicates the star formation subregions are more co-eval. DR7 and K3-50 have Lyman continuum photon rates just above the formal threshold criterion for being categorized as a GH ii region (1050 photons s−1) but with large enough errors that this classification is uncertain. By measuring other observational characteristics in the infrared, we find that K3-50 has properties more akin to previous bona fide GH ii regions we have studied, whereas DR7 has values more like those of the non-GH ii regions we have previously studied.
Wide-binary Stars Formed in the Turbulent Interstellar Medium
Authors: Xu Siyao , Hwang Hsiang-Chih , Hamilton Chris , Lai Dong
Published: June 2023

The ubiquitous interstellar turbulence regulates star formation and the scaling relations between the initial velocity differences and the initial separations of stars. We propose that the formation of wide binaries with initial separations r in the range ∼103 au ≲ r ≲ 105 au is a natural consequence of star formation in the turbulent interstellar medium. With the decrease of r, the mean turbulent relative velocity v
tur between a pair of stars decreases, while the largest velocity v
bon at which they still may be gravitationally bound increases. When v
tur < v
bon, a wide binary can form. In this formation scenario, we derive the eccentricity distribution p(e) of wide binaries for an arbitrary relative velocity distribution. By adopting a turbulent velocity distribution, we find that wide binaries at a given initial separation generally exhibit a superthermal p(e), irrespective of the exact turbulent velocity scaling. This provides a natural explanation for the observed superthermal p(e) of the wide binaries in the solar neighborhood.

Published: June 2023

The exploration of icy body composition in the solar system has often involved spectroscopic measurements of volatiles detected with remote sensing, such measurements portray materials naturally expelled from the surface that enter the exosphere and potentially escape into space. Variations in the ratio of deuterium and hydrogen in these measurements have led to inconclusive hypotheses regarding potential cometary origins of Earth’s ocean water and/or organics. Observational biases regarding unknown previous processing of the observable ejected materials necessitates studies of more dormant, less-processed bodies. Landed missions on comets have brought focus onto the development of small, sensitive instrumentation capable of similar composition measurements of the nascent surface and near-surface materials. We present an evolution of our compact Fourier-transform millimeter-wave cavity spectrometer that is tuned for sensitivity at 80.6 and 183 GHz where HDO and H2O exhibit resonance features. We discuss both a low-SWaP (size–weight and power) architecture that uses custom microchip transceiver elements as well as a modular configuration using traditional GaAs-based millimeter-wave hardware. New design features for these systems including quartz-based coupling elements, system thermal management, and a separable clocking board are discussed in addition to sensitivity studies and applications in potential mission scenarios.

Published: June 2023

The Distributed System of Scientific Collections (DiSSCo) is a new world-class Research Infrastructure (RI) for Natural Science Collections. The DiSSCo RI aims to create a new business model for one European collection that digitally unifies all European natural science assets under common access, curation, policies and practices that ensure that all the data is easily Findable, Accessible, Interoperable and Reusable (FAIR principles). DiSSCo represents the largest ever formal agreement between natural history museums, botanic gardens and collection-holding institutions in the world.

DiSSCo entered the European Roadmap for Research Infrastructures in 2018 and launched its main preparatory phase project (DiSSCo Prepare) in 2020. DiSSCo Prepare is the primary vehicle through which DiSSCo reaches the overall maturity necessary for its construction and eventual operation. DiSSCo Prepare raises DiSSCo’s implementation readiness level (IRL) across the five dimensions: technical, scientific, data, organisational and financial. Each dimension of implementation readiness is separately addressed by specific Work Packages (WP) with distinct targets, actions and tasks that will deliver DiSSCo’s Construction Masterplan. This comprehensive and integrated Masterplan will be the product of the outputs of all of its content related tasks and will be the project’s final output. It will serve as the blueprint for construction of the DiSSCo RI, including establishing it as a legal entity.

DiSSCo Prepare builds on the successful completion of DiSSCo’s design study, ICEDIG and the outcomes of other DiSSCo-linked projects such as SYNTHESYS+ and MOBILISE.

This paper is an abridged version of the original DiSSCo Prepare grant proposal. It contains the overarching scientific case for DiSSCo Prepare, alongside a description of our major activities.

On a souvent résumé la présence importante des avocats dans la vie politique française sous la III e  République à travers l’expression de « République des avocats. » De manière plus complexe, il s’agit de montrer comment les avocats sont au cœur, dans les premières décennies de la République, de la construction d’un champ politique marquée par la codification des règles électorales et une certaine démocratisation du personnel politique. Dans les décennies qui suivent, on note une diversification des formes d’investissement du barreau en politique, moins marqué par l’investissement dans le champ politique proprement dit que par l’engagement à travers la défense judiciaire de causes.
À l’école des séries judiciaires : la fiction au service de la représentation télévisuelle de l’avocat et de la justice aux États-Unis et en France
Authors: Villez Barbara
Published: June 2023

Les séries judiciaires à la télévision offrent un accès facile aux repères sur la justice et les professions liées dans un contexte de divertissement ainsi favorisant la disponibilité des téléspectateurs, ce qui favorise par la suite l’acquisition d’une culture juridique. Les séries américaines, souvent écrites par des équipes mixtes dans lesquelles participent des juristes, proposent depuis plus de soixante ans une image positive de l’avocat comme défenseur – sauveur, une personne sur qui on peut compter pour une protection contre un appareil judiciaire menaçant. La France a longtemps préféré produire des documentaires et diffuser des séries judiciaires étrangères en grand nombre, notamment celles des États-Unis. Récemment, l’abondance de ces fictions a diminué sur les grilles de programmes en France qui se lance dans la production de leurs propres séries judiciaires annonçant une nouvelle tendance et donnant une image plus positive de ces auxiliaires de justice.
Pastorale sandienne : pour une éc(h)ologie au féminin
Authors: Vallois Claire
Published: June 2023

Reconnue de nos jours comme une des pionnières du « réalisme vert » en littérature, mais aussi une des premières à donner vie au « réalisme magique » écologique dans Contes d’une grand-mère , George Sand ouvre la voie, par ailleurs, dans son œuvre autobiographique, Histoire de ma vie , à ce qui se trouve classé, de nos jours, sous le registre de l’ « écopsychologie ». Dans ce livre, Sand remonte au récit archaïque de sa relation à la mère, qui l’initie à l’amour et la connaissance de la nature. Fille d’un oiseleur parisien, celle-ci, comme une antique fée/sorcière, lui donne la « clé magique » des mystères de la terre-mère que les écologistes modernes ne craignent pas de nommer, par solidarité, et en écho aux discours des peuples autochtones, Gaïa, la Grande mère.
L’enfant en danger ou en risque de danger
Authors: Beyssade Sylvie
Published: June 2023

La loi du 5 mars 2007 réformant la protection de l’enfance substitue à la notion « d’enfants maltraités » la notion « d’enfants en danger et en risque de l’être ». L’imprécision des critères définissant le danger et le risque de danger, permet de faire des signalements sur la base de suppositions voire de suspicions. Ceci se traduit par un accroissement du nombre de signalements, une augmentation des dépenses et une absence d’homogénéité dans la déclinaison des politiques de protection de l’enfance sur l’ensemble du territoire. Dans le même temps, la notion de risque de danger justifie un principe de précaution qui fait fi de la présomption d’innocence, condamnant ainsi les parents à des sanctions avant même qu’ils aient été déclarés coupables par un juge.
Habitat précaire, actions sociales : des obstacles politiques
Authors: Poilliot Victor
Published: June 2023

Privées durablement de logement, de nombreuses personnes se réfugient dans les espaces ruraux en s’installant dans des habitats bricolés, plus ou moins aménagés, dont les formes varient : cabanes, locaux agricoles, tentes, caravanes, véhicules. Alerté.es par ces situations, les travailleur.ses sociaux.ales sont empêché.es dans leurs démarches par des obstacles politiques et législatifs qui marginalisent ces situations. Invisibles pour les politiques publiques, ces situations réinterrogent globalement les dispositifs de l’État en matière de droit au logement et d’amélioration du logement.
La pluralité de la recherche en design : tentative de clarification et de modélisation de la recherche-action, de la recherche-création et de la recherche-projet
Authors: Raîche-Savoie Geneviève , Déméné Claudia
Published: June 2023

Les maîtrises (ou masters) en recherche en design permettent aux étudiant·e·s de se spécialiser en explorant un objet d’étude de leur choix avec une formation axée sur une démarche scientifique. À partir d’une étude de cas sur la maîtrise en design avec mémoire (MDM) à l’École de design de l’Université Laval, il appert qu’une certaine confusion s’observe chez les étudiant·e·s face à la recherche-action, la recherche-création et la recherche-projet dont les frontières sont perméables. Dans le but d’aider les apprenti·e·s chercheur·euse·s, cet essai théorique tente de clarifier ces trois types de recherche en proposant un modèle conceptuel mettant en lumière leurs divergences et convergences. Une analyse critique d’une trentaine d’articles scientifiques a été réalisée, puis complétée par trois entrevues semi-dirigées auprès de chercheur·euse·s utilisant la recherche-action, la recherche-création et la recherche-projet dans leur démarche de recherche. Trois principales contributions se dégagent de cette recherche : i) la recherche-action se distingue principalement de la recherche-projet et de la recherche-création du fait qu’elle ne mène pas à un artefact ; ii) en recherche-création, l’artefact se développe de façon concomitante à la recherche par le biais de la création ; iii) en recherche-projet, la recherche se fait généralement en amont et permet de planifier en aval le projet de conception qui mènera à l’artefact.
Déploiement de l’IA en situation de travail : une trop faible considération de l’expérience des employé·es ?

Published: June 2023

Les récents travaux sur l’acceptabilité des solutions intégrant de l’intelligence artificielle (IA) en situation de travail se focalisent sur la prise en compte des facteurs humains et des facteurs intrinsèques à l’outil comme déterminants de l’adoption par les employé·es. Dans cet article, nous retraçons le déploiement d’outils professionnels basés sur de l’IA dans trois cas d’usage. Nous avons exploré les motivations de ces acteurs novices dans ce type de technologie, les moyens déployés pour mener à bien leur projet ainsi que la place accordée aux employé·es dans le processus de conception. Nous constatons que l’acceptabilité des solutions IA dans ces cas d’usage semble se limiter à l’acceptation de la performance et à un retour sur investissement (ROI) à court terme au détriment de la prise en compte des besoins et craintes des employé·es. Les conséquences directement observables sont des expériences plutôt négatives pour les employé·es, un retour sur investissement peu concluant et/ou la mise à l’écart de projets. Pour limiter les risques de rejet, nous suggérons de renforcer une approche plus holistique avec des considérations mises en avant par l’UX Design. Cela se traduit notamment par le fait de déterminer les besoins du réseau de parties prenantes, d’éviter le solutionnisme technique, d’optimiser les interfaces utilisateurs pour réduire la complexité inutile et de dimensionner les solutions techniques de manière appropriée à la tâche.
Reducing Drug Overdose Deaths: Significant Changes Needed in U.S. Drug Treatment Policy
Authors: Tierney Matthew , Flentje Annesa
Published: June 2023

Slow and incremental changes in federal and state drug policies are neither meeting treatment needs nor reversing yearly increases in drug-related mortality. U.S. drug policies convey confounding messages that non-sanctioned substance use leads to health problems that need treatment while simultaneously being legal problems that must be punished. As a result, drug treatments remain a sequestered component of health care, with onerous treatment requirements for patients and providers that act as barriers to the treatment that policies seek to allow. A new direction in drug policy is needed that broadens rather than restricts access to care and that also focuses on prevention. Policies must consider the totality of health and wellness, not just “last resort” safety nets for urgent needs. For substantive change in drug-related morbidity and mortality, forward-thinking policy must focus more on addiction prevention and address the known risks of developing a substance use disorder.

Purpose: This study aims to verify whether the Reflective Practice Questionnaire (RPQ) developed by Priddis and Rogers is valid in the Korean context to identify the level of reflection of medical students in clinical practice.Methods: A total of 202 third- and fourth-year medical students from seven universities participated in the study. After receiving approval for use from the authors, a survey was conducted on the students through an adaptation process. The original scale consists of 10 factors with 40 items. The Self-efficacy in Clinical Performance Scale (SECP), Korean Self-reflection and Insight Scale (K-SRIS), and Reflection-in-Learning Scale (RinLS) were used to validate the scale. Exploratory factor, confirmatory factor, correlation, and reliability analyses were used for data analysis.Results: As a result of exploratory factor analysis, 10 subfactors were extracted (Kaiser-Meyer-Olkin=0.856, Bartlett’s test: χ 2 =5,044.337, degrees of freedom=780, p<0.001). Among the 40 items, one that showed a high overlapping load for other factors was excluded. As a result of confirmatory factor analysis, the 10-factor structure model was found suitable (χ 2 =1.980, comparative fit index=0.859, Tucker-Lewis index=0.841, root mean square error of approximation=0.070). As a result of the criterion validity test, most of the subfactors of the Korean version of the RPQ (K-RPQ) showed a positive correlation with K-SRIS, RinLS, and SECP. The reliability of 10 subfactors was satisfactory, ranging from 0.666 to 0.919.Conclusion: The K-RPQ was confirmed to be a reliable and valid tool to evaluate the level of reflection among Korean medical students in clinical clerkship. This scale can be used as a tool to provide feedback on each student’s level of reflection in clinical clerkship.
