Published: March 2024

The emergence of the petition for judicial review of Case Number 114/PUU-XX/2022 against Law Number 7 of 2007 concerning General Elections has raised the political temperature of the country. The petitioners argued that the open proportional system was contrary to the 1945 Constitution and should therefore be replaced with a closed proportional system. The petitioners, who are political party officials, feel that the open proportional system has harmed their constitutional rights. This study aims to determine the extent to which the implementation of elections using an open proportional system can make the implementation of elections more democratic or, on the contrary, has created corrupt elections. A better alternative electoral system needs to be encouraged to realise a higher quality democracy. In general, the research method used in this research uses normative research by prioritising literature studies. The study is directed to be able to answer various problems that have been formulated as problem formulations. The result of this research is that elections with an open proportional system in reality cause rampant money politics, this is as a result of the intense internal competition of political parties. Therefore, it is necessary to encourage alternatives to make changes to the electoral system. The benefits of this research are expected to provide input to all stakeholders in elections, both the House of Representatives of The Republic of Indonesia (DPR RI), the Government, election organisers and political parties.

Putusan Mahkamah Konstitusi Nomor 16/PUU-XII/2014, salah satu permohonan pengujiannya adalah terkait Pasal 30 ayat (2) sampai (8) UU KPK, yaitu mengenai keterlibatan Dewan Perwakilan Rakyat dalam rekrutmen calon anggota Komisi Pemberantasan Korupsi. Keterlibatan DPR dalam pengisian jabatan publik diatur dalam Undang-Undang Dasar Negara Republik Indonesia Tahun 1945 (UUD 1945) dan di luar UUD 1945. Dengan luasnya kewenangan DPR, maka tujuan dalam penelitian ini adalah mengetahui bagaimana konstitusionalitas persetujuan DPR dalam pengisian jabatan publik. Penelitian ini merupakan penelitian normatif yang dilakukan dengan pendekatan perundang-undangan (statute approach), pendekatan kasus, dan pendekatan konseptual. Pengumpulan bahan hukum dilakukan dengan cara studi kepustakaan terhadap bahan hukum primer dan bahan hukum sekunder. Open legal policy merupakan dalil yang digunakan Mahkamah Konstitusi dalam putusannya, sehingga apa yang dilakukan DPR tidaklah menyimpang dari UUD 1945, Selain tentang konstitusionalitas, keterlibatan DPR dalam pengisian jabatan publik merupakan salah satu cara untuk menjalankan tugasnya sebagai lembaga negara yang salah satu fungsi utamanya adalah pengawasan. Sehingga keterlibatan DPR dalam pengisian jabatan publik dapat dikatakan sistem check and balances.

Delegation and Employee Prosocial Behaviour in the Hospitality Sector in Port Harcourt
Authors: Nsirim Hannah Orokwu
Published: March 2024

This study primarily examined the relationship between delegation and employee prosocial behaviour in the hospitality sector in Port Harcourt. The study adopted the cross-sectional research survey design. Primary data was generated through structured questionnaire. The population of the study was 1674 employees of 11 selected hotels in Port Harcourt. The sample size was also drawn using the Krejcie and Morgan (1980) sample size determination table. The reliability of the instrument was achieved by the use of the Cronbach Alpha coefficient with all the items scoring above 0.70. The hypotheses were tested using the Spearman’s Rank Order Correlation Coefficient. The tests were carried out at a 0.05 significance level. The findings revealed that there is a significant relationship between delegation and employee prosocial behaviour in the hospitality sector in Port Harcourt. Hence, the study concludes that delegation positively enhances employee prosocial behaviour in the hospitality sector in Port Harcourt. Implying that when organizations in hospitality sector actively engage in joint consultation practices, such as open communication, collaboration, and employee involvement in decision-making, there is a notable improvement in prosocial behaviors among employees. Therefore, the study recommends that there is a need to strengthen delegation platforms which involves creating structured forums where both management and employees can engage in meaningful discussions. This could include regular town hall meetings, feedback sessions, and collaborative workshops. By fostering an environment of open communication, these platforms can serve as a foundation for building a positive relationship between stakeholders.
Effect of Crude Oil Price Shock on Inflation and Exchange Rate in Nigeria

Published: March 2024

The study examined the effect of crude oil price shock on inflation and exchange rate in Nigeria. The study adopted an ex-post facto research design, covering the period between 1990 and 2022. Secondary data were extracted from the CBN Statistical Bulletin and World Development Indicators. Multiple regression technique was used for test of hypotheses. The findings revealed a noteworthy adverse effect of oil price shocks on Nigeria's inflation rate, indicated by a probability value of 0.0180. Additionally, the impact of oil price shocks on exchange rates in Nigeria was also adverse and statistically significant, as reflected by a probability value of 0.047. Moreover, these findings align with established economic theory. The negative effect of oil price shocks on the exchange rate can be explained by the consistent devaluation of the Naira relative to the US Dollar in response to abrupt, particularly negative, changes in oil prices. The study, therefore, recommended that the government should enhance the proportion of funds allocated to the excess crude accounts relative to its revenue expenditures. By doing so, the government can build a financial cushion that can be tapped into when price shocks disrupt the crude oil market. Furthermore, it is advisable to employ contractionary monetary and fiscal policies when price shocks occur. These policies can effectively counteract excessive cost-push inflation that may result from the shocks. By reducing the overall demand in the economy through measures like higher interest rates and reduced government spending, inflationary pressures can be curbed.

Published: March 2024

En este documento se realiza un análisis en lo que respecta a la importancia del papel del rector como directivo en la consecución de un excelente desempeño de los docentes que conforman su equipo de trabajo y el alcance de la calidad en las instituciones educativas. El objetivo principal es aproximarse de manera reflexiva a la significación de la gestión directiva en el alcance de la calidad educativa. En este sentido en este documento se sugiere el no caer en reduccionismos cuando se habla de gestión directiva ya que va más allá de una llana administración de organizaciones educativas, implica además de gestionar los recursos físicos y financieros el gestionar al recurso con mayor repercusión en el alcance de los objetivos institucionales y en general en el aseguramiento de la calidad educativa; el talento docente. De esta manera se enfatiza la importancia de la realización de las actividades administrativas de planeación, organización, dirección y control desde el liderazgo. Finalmente, se resalta el papel del rector en la creación de una visión compartida y ambientes cooperativos que favorezcan la movilización del personal docente y la creación de culturas y contextos de aprendizaje apropiados que les permitan aproximarse a la calidad institucional.

Las fracturas de la meseta tibial representan el 1% de las fracturas musculoesqueléticas y el 8% de las fracturas en pacientes de edad avanzada y son un tipo común de lesión de las extremidades inferiores que se observa en personas con una distribución de edad bimodal. Estas lesiones suelen clasificarse mediante la clasificación de Schatzker, que evalúa el grado de desplazamiento de la fractura, el número de fragmentos óseos y la extensión de la lesión para determinar el tratamiento específico y predecir el pronóstico a largo plazo. Estas fracturas suelen estar asociadas con accidentes de vehículos de alta energía; también se presentan en adultos mayores con mecanismos de baja energía por caídas simples por osteoporosis. La mayor proporción de fracturas de meseta tibial se tratan quirúrgicamente, siguiendo el principio de restaurar la congruencia de la superficie articular y preservar el eje mecánico de la extremidad. Si hay daño meniscal, se complicará con artrosis postraumática. La incidencia es del 75% 10 años después de la cirugía. Si no hay daño meniscal, se puede reducir al 30%. Paciente masculino de 28 años que sufre accidente en motocicleta hace 7 días, acude por presentar edema leve en rodilla izquierda compatible con posible absceso, se acompañada de dolor de impotencia funcional del miembro inferior izquierdo, motivo por el cual acude a casa de salud más cercana.

La tuberculosis sigue siendo una de las principales causas de muerte en todo el mundo. La propagación de la tuberculosis al cerebro da como resultado la forma más grave de tuberculosis extrapulmonar, la meningitis tuberculosa, una emergencia médica asociada con una alta mortalidad y discapacidad. Mycobacterium tuberculosis se propaga desde el sitio de la infección primaria y supera las barreras protectoras para ingresar al sistema nervioso central mediante varios mecanismos. Allí, desencadena una respuesta inflamatoria que involucra células inmunes periféricas y residentes e inicia una cascada de mecanismos patológicos que pueden controlar la enfermedad o causar daño cerebral grave. La meningitis tuberculosa (TBM) es la manifestación extrapulmonar más grave de la tuberculosis, con tasas de mortalidad de hasta el 50% asociadas con la coinfección por VIH-1. La patogénesis de la TBM no se comprende completamente y se necesita mayor conocimiento para desarrollar vacunas efectivas, antibióticos óptimos y terapias específicas para el huésped. Se reporta paciente masculino de 50 años, sin antecedentes patológicos de importancia que refiere cefalea intensa acompañado de alzas térmicas no cuantificas por varios días de evolución, hace 1 hora sintomatología se exacerba y presenta alteración del estado de conciencia motivo por el cual es llevado a la casa de salud más cercana.

El síndrome de Takotsubo (TTS) se describió por primera vez en 1990 en Japón. La fisiopatología del síndrome de takotsubo sigue siendo controvertida. Este síndrome es común en mujeres posmenopáusicas mayores que experimentan estrés emocional y físico repentino e inesperado. Inicialmente se pensó que las manifestaciones clínicas del síndrome de Takotsubo, similares a las del infarto agudo de miocardio, tenían un mejor pronóstico que el infarto de miocardio, pero estudios posteriores han demostrado una tasa de mortalidad más alta que la informada anteriormente. Las complicaciones agudas como insuficiencia cardíaca, arritmias, trombos intraventriculares y obstrucción del tracto de salida del ventrículo izquierdo requieren un diagnóstico inmediato y un tratamiento adecuado. Sin embargo, el STT se diferencia de los síndromes coronarios agudos en que los pacientes suelen tener una angiografía coronaria normal y una disfunción ventricular izquierda que excede el área cubierta por una única arteria coronaria y se recupera en días o semanas. Se reporta un paciente masculino de 50 años, sin antecedentes de importancia quien refiere vómitos de contenido alimentario por 3 ocasiones acompañados de sincope vasovagal, a la consulta refiere dolor tipo anginoso, opresivo localizo en región anterior de tórax que se irradia a mandíbula y brazo izquierdo.
Insider threat mitigation through human intelligence and counterintelligence: A case study in the shipping industry
Authors: Kanellopoulos Anastasios-Nikolaos
Published: March 2024

This paper comprehensively examines the multifaceted motivations behind insider threats within organizations, elucidating driving forces such as financial gain, revenge, personal aspirations, ideological beliefs, coercion, and negligence. Understanding this spectrum is fundamental for crafting effective Counterintelligence strategies. The study delves into behavioral indicators crucial for identifying potential threats, emphasizing the significance of recognizing warning signs like unusual data access, unsanctioned software usage, escalated privilege requests, poor performance, disagreement with policies, and more.
Furthermore, the role of Human Intelligence (HUMINT) in Counterintelligence (CI) and insider threat detection is explored, highlighting its qualitative contribution to understanding human behavior. Plus, through a hypothetical case study in the Shipping industry, the paper illustrates the direct application of HUMINT principles in fortifying security against insider threats, considering the unique challenges of this dynamic sector. The case study strategically employs employee interviews, psychological assessments, social network analysis, and trust-building initiatives to proactively identify and mitigate potential threats, in an industry reliant on seamless global supply chain operations.
The Effect of Expressive Writing Therapy on Self-Efficacy and Subjective Well-Being Students
Authors: Mianti Rizka , Hasanuddin Hasanuddin , Dewi Salamiah Sari
Published: March 2024

High academic pressure, personal obstacles, and the challenges brought by the pandemic can lead to stress and diminished self-confidence in students. In this context, self-efficacy and subjective well-being emerge as crucial factors influencing the learning process. Barriers such as a lack of outlets for expressing emotions and difficulties in overcoming problems can impede students' academic journey. This research conducted at SMA Negeri 1 Bangun Purba aims to examine the impact of expressive writing therapy on students' self-efficacy and subjective well-being. The study involves the development of an expressive writing therapy module, incorporating a scale with validated and reliable measures. The application of this therapy to students follows a quasi-experimental method using a nonequivalent control group design. The research sample consists of two groups: an experimental group subjected to expressive writing therapy and a control group. The results indicate that in the control group, there is no significant difference in self-efficacy (Wilcoxon test, p=0.0798) and subjective well-being (t-test, p=0.3691) before and after the post-test. However, in the experimental group, a significant difference is observed in both self-efficacy (t-test, p<0.05) and subjective well-being (Wilcoxon test, p<0.05). Simultaneously, both aspects can be enhanced through expressive writing therapy (MANOVA, p<0.05). This research highlights that the developed expressive writing therapy module effectively improves students' self-efficacy and subjective well-being.
Mean Sea Level: The Effect of the Rise in the Environment
Authors: Isiaka Ibrahim , Ndukwe Kingsley , Chibuike Ufomba
Published: March 2024

Mean sea level is a significant phenomenon in geodetic science and oceanography. The sea level has experienced an unprecedented rise recently, and this increase can be attributed to various human-induced activities (anthropogenic factors) ranging from deforestation to the burning of fossil fuels and population increases. Several factors cause sea level rise. It has been identified that the thermal expansion of ocean water and the melting of glaciers add to the volume of water, causing global sea level to rise, whereas phenomena such as ocean current, wind, and pressure are responsible for the regional sea level rise. This paper identifies climate change and global warming as the drivers of some factors causing sea level to rise. The effect of sea-level rise has resulted in the loss of agricultural lands, the destruction of transportation infrastructure, the loss of lands in coastal zones and migration, and the death of some aquatic animals due to saltwater intrusion. In this paper, we reviewed several pieces of literature published between 2017 and 2021 on sea-level rise and the cascading impacts of sea-level rise in various world areas. The papers reviewed borders on the mean sea level rise from different geographical areas on Earth and the monitoring of sea-level rise using different techniques. Some recommendations were also proposed for consideration.

We present results from a systematic search for broad (≥ 400 km s−1) Hα emission in integral field spectroscopy data cubes of ∼1200 nearby galaxies obtained with PMAS and MUSE. We found 19 unique regions that pass our quality cuts, four of which match the locations of previously discovered supernovae (SNe): one Type IIP and three Type IIn, including the well-known SN 2005ip. We suggest that these objects are young Supernova remnants (SNRs), with bright and broad Hα emission powered by the interaction between the SN ejecta and dense circumstellar material. The stellar ages measured at the locations of these SNR candidates are systematically lower by about 0.5 dex than those measured at the locations of core-collapse (CC) SNe, implying that their progenitors might be shorter lived and therefore more massive than a typical CCSN progenitor. The methods laid out in this work open a new window into the study of nearby SNe with integral field spectroscopy.

An intensive reverberation mapping campaign of the Seyfert 1 galaxy Mrk 817 using the Cosmic Origins Spectrograph on the Hubble Space Telescope revealed significant variations in the response of broad UV emission lines to fluctuations in the continuum emission. The response of the prominent UV emission lines changes over an ∼60 day duration, resulting in distinctly different time lags in the various segments of the light curve over the 14 month observing campaign. One-dimensional echo-mapping models fit these variations if a slowly varying background is included for each emission line. These variations are more evident in the C iv light curve, which is the line least affected by intrinsic absorption in Mrk 817 and least blended with neighboring emission lines. We identify five temporal windows with a distinct emission-line response, and measure their corresponding time delays, which range from 2 to 13 days. These temporal windows are plausibly linked to changes in the UV and X-ray obscuration occurring during these same intervals. The shortest time lags occur during periods with diminishing obscuration, whereas the longest lags occur during periods with rising obscuration. We propose that the obscuring outflow shields the broad UV lines from the ionizing continuum. The resulting change in the spectral energy distribution of the ionizing continuum, as seen by clouds at a range of distances from the nucleus, is responsible for the changes in the line response.
Low-mass Stars: Their Protoplanetary Disk Lifetime Distribution
Authors: Pfalzner Susanne , Dincer Furkan
Published: March 2024

While most protoplanetary disks lose their gas within less than 10 Myr, individual disk lifetimes vary from <1 Myr to ≫20 Myr, with some disks existing for 40 Myr. Mean disk half-lifetimes hide this diversity; only a so-far nonexisting disk lifetime distribution could capture this fact. The benefit of a disk lifetime distribution would be twofold. First, it would provide a stringent test on disk evolution theories. Second, it could function as an input for planet formation models. Here, we derive such a disk lifetime distribution. We heuristically test different standard distribution forms for their ability to account for the observed disk fractions at certain ages. We here concentrate on the distribution for low-mass stars (spectral types M3.7–M6, M

s
≈ 0.1–0.24 M
⊙) because disk lifetimes depend on stellar mass. A Weibull-type distribution (k = 1.78, λ = 9.15) describes the observational data if all stars have a disk at a cluster age t

c
= 0. However, a better match exists for lower initial disk fractions. For f(t=0) = 0.65, a Weibull distribution (k = 2.34, λ = 11.22) and a Gaussian distribution (σ = 9.52, μ = 9.52) fit the data similarly well. All distributions have in common that they are wide, and most disks are dissipated at ages >5 Myr. The next challenge is to quantitatively link the diversity of disk lifetimes to the diversity in planets.
Acceleration and Release of Solar Energetic Particles Associated with a Coronal Shock on 2021 September 28 Observed by Four Spacecraft

Published: March 2024

The main driver of the acceleration of solar energetic particles (SEPs) is believed to be shocks driven by coronal mass ejections. Extreme-ultraviolet (EUV) waves are thought to be the propagating footprint of the shock on the solar surface. One of the key questions in SEP research is the timing of the SEP release with respect to the time when the EUV wave magnetically connects with an observer. Taking advantage of close-to-the-Sun measurements by Parker Solar Probe (PSP) and Solar Orbiter (SolO), we investigate an SEP event that occurred on 2021 September 28 and was observed at different locations by SolO, PSP, STEREO-A, and near-Earth spacecraft. During this time, SolO, PSP, and STEREO-A shared similar nominal magnetic footpoints relative to the SEP source region but were at different heliocentric distances. We find that the SEP release times estimated at these four locations were delayed compared to the times when the EUV wave intercepted the footpoints of the nominal magnetic fields connecting to each spacecraft by around 30–60 minutes. Combining observations in multiple wavelengths of radio, white light, and EUV with a geometrical shock model, we analyze the associated shock properties and discuss the acceleration and delayed release processes of SEPs in this event as well as the accuracy and limitations of using EUV waves to determine the SEP acceleration and release times.
Relationships and description of a new catfish species from Chapada Diamantina, the northernmost record of Trichomycterus s.s. (Siluriformes, Trichomycteridae)

Published: March 2024

Psammocambeva exhibits the largest geographical distribution amongst the subgenera of Trichomycteruss.s., with its present northernmost represented by Trichomycterus tete, endemic to the upper Rio de Contas Basin in the Chapada Diamantina Region, north-eastern Brazil. Herein, we describe a new species recently collected in the Chapada Diamantina Region, but in the Rio Paraguaçu Basin, about 100 km north of the area inhabited by T. tete. A molecular phylogeny using one nuclear and two mitochondrial genes (2430 bp) supported the new species as sister to T. tete; both species are distinguished by colour patterns, morphometric data, relative position of dorsal and anal fins and osteological character states. The clade comprising the new species and T. tete, endemic to the semi-arid Caatinga biogeographical province, is supported as sister to a clade comprising species from the Rio Doce and Rio Paraíba do Sul Basins, in the Atlantic Forest biogeographical province. This study corroborated the Chapada Diamantina Region, a well-known mountainous biodiversity centre, as an important centre of endemism for trichomycterid catfishes.
Répression, droit et justice. La punition du vol de la propriété publique en Union soviétique pendant la collectivisation des campagnes (1932-1933)
Authors: Cadiot Juliette
Published: March 2024

Cet article étudie la reconfiguration institutionnelle et juridique de l’Union soviétique consécutive à la crise majeure qu’a représentée la collectivisation des campagnes du début des années 1930. Il s’intéresse plus particulièrement au décret punissant le vol de la propriété publique d’août 1932. Émise sous l’ordre direct de Staline dans un contexte de terrible famine, notamment en Ukraine, ce décret public fut appliqué aussi bien par les tribunaux ordinaires, les tribunaux du peuple que par les troiki , tribunaux d’exception de la police politique. Ce dualisme, ou encore cet État double, normatif et prérogatif, si l’on reprend la formule d’Ernst Fraenkel, se reconfigura au cours de cette campagne punitive qui vit se succéder terreur dans les campagnes, assouplissement des peines par un retour au code pénal et opérations d’amnistie. Cette évolution chaotique aboutit à un changement dans la législation : la protection de la propriété socialiste devint un devoir du citoyen soviétique. Le démantèlement progressif des tribunaux d’exception, les troiki , marqua aussi une étape en transférant les affaires dites politiques aux tribunaux ordinaires. Mais cette normalisation est trompeuse, car des cours spéciales contrôlées par la police politique furent mises en place au sein des tribunaux du peuple.
Agency and Aspiration: How Twenty-First Century China Complicates our Understanding of Authoritarian Law
Authors: Stern Rachel E.
Published: March 2024

Résumé Cet article examine deux thèmes dans les publications récentes sur le droit chinois qui compliquent l'image durable du droit autoritaire comme exclusivement répressif : l’ambition et l'agentivité. Premièrement, l’émergence de la Chine comme puissance mondiale s’est reflétée dans le système juridique, où les tribunaux s’efforcent d’innover et d’exceller. Cette ambition est particulièrement claire dans l’adoption par les tribunaux des technologies et de l'intelligence artificielle. Deuxièmement, le thème de l'agentivité met en évidence les choix stratégiques disponibles pour les juges, les plaideurs et les autres qui interagissent avec le système juridique. Ces choix sont illustrés par des poursuites concernant l’accès aux informations gouvernementales et l’obligation pour des chefs de gouvernement chinois de comparaître devant le tribunal si leur département est poursuivi. Ces exemples montrent que le choix est réel, même s’il est également sévèrement limité.
An inverse problem to estimate simultaneously the heat source strength for multiple integrated circuit chips on a printed circuit board
Authors: Huang Cheng-Hung , Zhong Ya-Rou
Published: March 2024

In this three-dimensional steady-state inverse heat transfer problem, we determine the magnitude of the spatially dependent volumetric heat source originating from multiple encapsulated chips mounted on a printed circuit board (PCB). Prior to the estimations, the functional form of the multiple heat sources is treated as unknown, leading to its classification as a function estimation challenge within the realm of inverse problems. The utilization of the conjugate gradient method (CGM) as an optimization tool is rooted in its distinct advantage of not requiring any a priori knowledge regarding the functional form of the unidentified quantities. Furthermore, the CGM empowers the simultaneous correction and estimation of multiple unknowns during each iteration, thereby ensuring the consistent possibility of precise estimates.

To affirm the precision of the estimated heat source attributed to multiple chips, a series of numerical experiments were conducted. These experiments encompassed varying inlet air velocities and introduced measurement errors. Notably, the results revealed that meticulous measurements consistently yielded accurate heat generation assessments for the chips, regardless of the prevailing air velocity conditions. The findings underscored that the accuracy of chip heat generation estimates diminished as measurement errors escalated, predominantly due to the ill-posed nature inherent in the inverse problem.

In demanding application scenarios such as clinical psychotherapy and criminal interrogation, the accurate recognition of micro-expressions is of utmost importance but poses significant challenges. One of the main difficulties lies in effectively capturing weak and fleeting facial features and improving recognition performance. To address this fundamental issue, this paper proposed a novel architecture based on a multi-scale 3D residual convolutional neural network. The algorithm leveraged a deep 3D-ResNet50 as the skeleton model and utilized the micro-expression optical flow feature map as the input for the network model. Drawing upon the complex spatial and temporal features inherent in micro-expressions, the network incorporated multi-scale convolutional modules of varying sizes to integrate both global and local information. Furthermore, an attention mechanism feature fusion module was introduced to enhance the model's contextual awareness. Finally, to optimize the model's prediction of the optimal solution, a discriminative network structure with multiple output channels was constructed. The algorithm's performance was evaluated using the public datasets SMIC, SAMM, and CASME Ⅱ. The experimental results demonstrated that the proposed algorithm achieves recognition accuracies of 74.6, 84.77 and 91.35% on these datasets, respectively. This substantial improvement in efficiency compared to existing mainstream methods for extracting micro-expression subtle features effectively enhanced micro-expression recognition performance and increased the accuracy of high-precision micro-expression recognition. Consequently, this paper served as an important reference for researchers working on high-precision micro-expression recognition.

The multiple physical fields of hot mix asphalt (HMA) during the compaction process have a significant impact on the durability of asphalt pavement, and this research aimed to evaluate the synergistic effect of the HMA field compaction of multi-physical field evolution during the compaction process. First, the temperature field, structural layer thickness variation, and structural layer density variation were monitored during field compaction. Second, the evolution properties of compaction thickness were obtained under the synergistic influence of multi-physical fields by temperature field and compaction thickness. Finally, the evolution properties of compaction density were obtained under the synergistic influence of multi-physical fields based on the temperature field and structural layer density. The results showed that the field compaction process could be characterized by three stages under the synergistic impact of multi-physical fields. The cooling of the temperature field presents two-stage characteristics. There were cubic polynomial evolution properties for the temperature field versus time and the density versus temperature field. There was an exponential relationship between the thickness of the compacted layer and the number of mills. The aggregate particles showed different motion characteristics in the horizontal and vertical directions and vertical directions. The vertical displacement was larger than the horizontal displacement under the synergistic influence of multi-physical fields during the three stages of compaction. The migration and reorganization of aggregate particles affected the evolution of the multi-physics fields of the compaction process under the action of different compaction modes.
La place de la conception des technologies éducatives dans les inégalités socionumériques d’usage
Authors: Collin Simon
Published: March 2024

L’étude des inégalités socionumériques depuis les années 1990 a connu des développements théoriques et empiriques soutenus qui ont contribué à consolider ses assises scientifiques et à légitimer sa pertinence sociale, notamment en éducation et en formation. En revanche, elle a peu interrogé l’amont des inégalités socionumériques d’usage de sorte que le rôle de la conception dans la fabrique des inégalités socionumériques en éducation et en formation a peu été exploré. Aussi, l’objectif de cet article théorique est de clarifier la relation entre la conception des technologies éducatives et les inégalités socionumériques d’usage en éducation et en formation afin de mieux comprendre comment la première participe des secondes. Pour ce faire, nous mobilisons la métaphore du script proposée par Madeleine Akrich (1987) et reprise sous l’angle des rapports de pouvoir par les études féministes du Social Shaping of Technology (SST).
Apprendre à travailler ensemble : influences de l’espace de travail numérique sur l’engagement dans la collaboration

Published: March 2024

Cet article examine les conditions d’un engagement des apprenants dans un projet commun ainsi que les conditions de développement de compétences spécifiques pour collaborer. Pour mieux comprendre l’engagement dans la collaboration et les compétences qui y sont associées, nous nous appuyons sur les résultats d’une expérimentation mobilisant des tables et tableaux multitouches et multiutilisateurs. Nous avons cherché à mesurer les effets sur l’engagement des apprenants d’un tel dispositif sociotechnique de formation en comparant trois formes différentes d’instrumentation de l’activité collaborative : une table et un tableau tactiles ; un tableau tactile seul ; des tablettes numériques avec un tableau tactile. Cela nous permet de comparer comment la conception de ces espaces influence l’implication des individus dans la collaboration et les compétences collaboratives développées.

This chapter critically examines the legal categorization of forced marriage within the context of modern slavery, focusing on the need for legislative reform in England and Wales. It explores the intricate parallels between forced marriage and modern slavery, emphasizing shared elements of coercion, exploitation, and infringement of autonomy and consent. The discussion includes a philosophical analysis of forced marriage, considering feminist theories and the impact of patriarchal norms. By comparing the current legal frameworks of England and Wales with international standards set by the United Nations and the International Labour Organization, the chapter highlights discrepancies and advocates for harmonization. It underscores the importance of recognizing forced marriage as a form of modern slavery to ensure comprehensive legal responses, protection, and support for victims, culminating in a call for legal reform in England and Wales to align with global human rights efforts.
Human Trafficking in Tanzania
Authors: Mpandikizi Godfrey
Published: March 2024

Human trafficking is an issue that affects vulnerable individuals across the world, and Tanzania is no exception. The country has long been a source, transit, and destination for human trafficking, particularly for women and children who are exploited and used for forced labor, sexual exploitation, forced military servitude, and organ trafficking. Despite Tanzania's efforts to combat trafficking in persons in all of its forms, it remains classified as a Tier 2 country by the United States Department of State's Trafficking in Persons (TIP) Report. This classification indicates that while the government has made significant efforts to address human trafficking, it does not fully meet the minimum standards for the elimination of trafficking. In the fight against human trafficking, Tanzania's approach, like many countries globally, focuses on three pillars of combating trafficking in persons: prevention, prosecution, and protection. All three pillars are necessary to help eliminate the sources of trafficking, support survivors, and hold traffickers accountable for their crimes.
Casual or Casualty?

Published: March 2024

The ultimate goal of society is to maintain social order. This can be attained by restricting the menace of crime. Within crime, there is a category of 'victimless crime' – which may sound oxymoronic. The victimless crimes cover those crimes where victims are not identifiable, or the illegal activity that occurs with the parties' consent. For decades there has been debate on whether victimless activity should be criminalized or not. The argument by the modernized world is in favor of decriminalization due to the lack of harm to others and freedom of the individual. This chapter hypothesizes that 'victimless crimes have victims – society as a whole, hence the term victimless is a façade. The chapter will attempt to establish the correlation between Mill's Harm Principle viz-a-viz modern victimless crimes. Thereafter, the chapter will discuss the various victimless crimes prevalent in India & their impact on the subcontinent. Lastly, the chapter will summarize the arguments with concluding remarks on the criminological aspect of victimless crimes.
