Legislative Sovereignty, Executive Power, and Judicial Review: Comparative Insights from Brexit
Authors: Reyes René
Published: April 2022

In June 2016, participants in a United Kingdom referendum voted to leave the European Union (EU) by a margin of 52% to 48%. The timing and terms of Britain’s exit (commonly known as “Brexit”) are the subject of on-going public and parliamentary debate. But the mechanism by which Brexit is to be formally commenced was clarified by the U.K. Supreme Court at the end of January 2017 in the landmark case R (Miller) v. Secretary of State for Exiting the European Union. The question presented was whether ministers of Theresa May’s government could give notice of the U.K.’s withdrawal from the EU “without prior legislation passed in both Houses of Parliament and assented to by HM The Queen.” The secretary of state argued that the power to withdraw was part of the royal prerogative exercisable by ministers without prior parliamentary action. However, in light of the far-reaching changes to domestic law that would result from terminating EU membership treaties, the court held that withdrawal “must be made in the only way in which the UK constitution permits, namely through Parliamentary legislation.”

On the one hand, the Miller decision may be seen as a resounding reaffirmation of the principle of parliamentary sovereignty in British constitutional law. Notwithstanding the facts that a majority of voters supported Brexit and that government ministers ordinarily have the power to terminate treaties without legislative approval or judicial review, formal notice of withdrawal under Article 50 of the EU Treaties could not be given unless and until Parliament so agreed. Yet on the other hand, a comparative analysis of Miller also reveals some significant limitations on parliamentary power in the United Kingdom relative to congressional power in the United States—even though Congress is constrained by the Constitution and enjoys no sovereignty over the other branches of government. This Essay explores these limitations on parliamentary power and argues that legislative sovereignty is best understood not as an immutable principle laid down in Britain’s constitutional history, but rather as an evolving ideal that continues to develop to this day.

PERSONALIZING POTENTIALS OF WEBLOG IN EFL CLASSROOMS
Authors: Mali Yustinus Calvin Gai
Published: April 2022

A weblog (also called a blog) has been pervasively used as an alternative language learning technology in English as a Foreign Language (EFL) settings. However, there are still limited attempts to shed more lights on the (a) integration of various applications in the blog and (b) how they can be maximized for teaching and learning purposes in the context of Indonesian higher education. Therefore, this study aims to explore issues concerning the use of a tutor blog run in an English Education Study Program of a private university. The exploration focuses on the potentials of the tutor blog and their relevance to current blogging activities as well as draws on related literature and reflective experiences in utilizing the blog in EFL classrooms. This study seems to confirm the potentials of the tutor blog, as asserted by Campbell (2003). The analysis also reveals some possibilities of integrating the blog into other technological applications, which should be beneficial for pre-service and in-service EFL teachers who wish to utilize blogs to support their pedagogical agendas. The study concludes with directions for further studies.
A STUDY OF FILLERS UTTERED IN ENGLISH PUBLIC SPEAKING
Authors: Firiady Maryska , Mahendra Aloisius Wisnu
Published: April 2022

In the formal context of communication, capability to speak in public and convince the audiences becomes an essential necessity (Al-Tamimi, 2014). Nevertheless, many people are afraid of public speaking (Brewer, 2001). As a result, fillers such as err…, umm…, or well, so, you know, I mean are often produced. However, fillers are considered as additional utterances produced by speakers to communicate naturally with the listeners. They help the speakers to shift one idea to another to make the listeners understand the meaning conveyed by the speakers easily. This study investigated twenty English public speaking videos and looked for the variation of fillers uttered by the speakers. The results showed that so, err, and umm were the frequent fillers uttered. The use of these fillers had various functions such as to introduce the speaker’ ideas, to gain audience’s attention, or to give time for the speakers to search for the word.
LEXICAL ANALYSIS OF THE MOST FREQUENT ACADEMIC WORD IN STUDENTS’ ACADEMIC ESSAY
Authors: Budiartha Christianus I Wayan Eka , Ramadhan Yoga Pratama Putra
Published: April 2022

Writing as a productive skill in English has been valued greatly, especially in academic context. The process approach was started to be considered when teaching writing as it offers a more meaningful learning. Furthermore, the approach makes room for collaborative learning between students and teachers. For EFL students whose first language is not English, mastering writing skills could be more challenging. To address the issues, the idea of a writing center has been adapted in a higher educational level for students who want to improve their writing. The study was conducted by using a qualitative descriptive approach and its data collection was carried out through a number of instruments to fulfill the triangulation method of a qualitative approach such as observation, semi-structured interview, survey, and corpus-based research. From the eight purposive sampling of tutees and the four tutors, the study concluded that EFL students are not familiar with the process of writing, so many of them consider having support merely on revising their essay draft. Even though collaborative writing was successfully carried out, but EFL students need to improve their independent study to follow up the discussion they had with the tutors.

Published: April 2022

The authors proposed to consider business simulation as a modern educational technology adequate to economic reality, as an interactive model of the economic system, which, by its internal conditions, is as close as possible to the corresponding institutional unit: a division or an entire enterprise, industry, country. Based on the expert analysis, it was revealed that employers and students in universities have different assessments of the skills required for employment. This gap in the assessment of competencies can be partially leveled through the implementation of business simulation. The authors gave an analysis of the business simulation from the point of view of a competency-based approach. They identified groups of tasks that can be solved with the help of this educational technology, and formed the corresponding general cultural, general professional and professional competencies of students in economic areas of training. The authors identified the advantages of using business simulation in teaching, which lay the foundation for the formation of competencies: the possibility of using it in a distance form, activation of creative abilities, the development of creative thinking, independence and self-discipline of students, great interest of students in the learning process due to gamification, applied nature and a high degree proximity to economic reality, the ability to simultaneously solve many problems. The disadvantages of using business simulation were also considered: a lack of contact work between a teacher and a student, an increase in the time spent in front of the screen, the need for special training of teachers, excessive involvement in the game part of a business simulation, financial costs for technical development and the creation of the necessary infrastructure. Foreign business simulations are characterized, the use of which makes it possible to hone the skills of doing business and making optimal economic decisions. The problems and prospects of development in Russia of training based on business simulation were identified. It was emphasized that further research requires studying the experience of using business simulation games in universities and business schools.

Soil physical and chemical properties do affect forests (plant) growth and soil management systems. Some key and important physical and chemical properties of soil are mineral content, texture, cation exchange capacity, bulk density, structure, porosity, organic matter content, carbon-to-ni- trogen ratio, color, depth, fertility, and pH. Sustainable forest management and soil quality parameters may include such terrestrial functions as carbon sequestration, land use management, erosion control, plant productivity and a soil’s capacity to produce biomass. Sustainable forest management consistently requires enhancement of both the chemical and physical properties of forest soil quality. Land use and change in land use as well as forest management systems, are main indicators that may determine which soil properties induce changes in any forest site. Forest management and crop yield are key issues of environmental/productivity quality in addressing carbon mitigation and absorption in plant species and agricultural productivity. Five distinct forest soils under major physical properties and chemical properties were evaluated at the forest ecology laboratory. The results were determined while considering regional forest management regimes. Correlation analysis in Deqing forest soil showed that higher correlation of NMC at 25-50cm depth, BD at 0-25cm as well as 25-50cm while EC was high on 0-40 and 0.60 At the Guangzhou site, acidic levels (pH 0-25cm) indicated minor correlation and soil salinity (EC 25-50cm) also showed minor correlation. The trend was same the at the Changtan forest site where soil salinity showed only minor significant relationship (0-25cm). A percentage assessment of SOC (g/kg) among the forest sites by plot observation showed that Deqing forest site, Changtan and Nanling were well distributed which confers best forest management regimes that yield to good forest soil chemical and physical properties. This study gave scientific insight and boast plant functional nutrient interaction as well as stability towards better agricultural productivity and forest management systems. This is in agreement that good management and less disturbance in forest soils are major component of physical and chemical properties interaction, thereby for effective integrated forest and agricultural management systems.

Terrain critique
Authors: Maeder Thierry
Published: April 2022

Tour à tour tactique, temporaire, festif, participatif, créatif, humain, l’urbanisme a pris des formes inédites depuis le tournant du 21e siècle. Les notions d’affect, d’expérience et de design se sont installées progressivement dans l’éthos des professionnels de l’urbanisme, alors que celui-ci s’ouvrait à des acteurs inattendus et à de nouveaux arts-de-faire. Cette transformation est le produit d’un long dialogue entre pratique et critique : à la critique de l’expertise et de la mise à distance de l’habitant, l’urbanisme a répondu par la participation ; à la critique de la légitimité, il a répondu par la narrativité et la mise en scène célébrative de son action ; à la critique de la monotonie et de la morosité du modernisme, il a répondu par le recours à l’authenticité et à l’événementialisation des centres-villes. L’enquête qui fait l’objet de cet ouvrage dresse le récit d’une intégration progressive de l’action culturelle et artistique en urbanisme. Face à un contexte de défiance à son égard, elle décrit un urbanisme qui s’ouvre à des compétences en matière de médiation, d’animation et de communication. Et dépeint, à l’inverse, un monde de l’art impatient d’investir cette nouvelle niche de la commande publique urbaine. L’intrigue qui s’y joue laisse percevoir l’émergence d’un nouvel esprit de l’urbanisme.

Published: April 2022

Objective: The purpose of the present study was to reveal the experience of a single tertiary center in management and outcomes of tubo ovarian abscess (TOA) in postmenopausal patients.

Materials and Methods: The present study was conducted between January 2012 and June 2021. One hundred and twenty-seven hospitalized cases of TOA were identified from the medical records and retrospectively reviewed. Collected data included age, parity, menopausal status, intrauterin device (IUD) usage, smoking history, prior procedure, radiological findings, medical and surgical treatments, laboratory findings, pathology and length of hospital stay.

Results: The mean age of all patients were 39.2 ± 9.8 years, and 22 (17.3%) patients were postmenopausal. The need for surgical intervention, the intrauterine device usage, duration of hospitalization, and malignancy at final pathology were significantly higher in postmenopausal patients (p < 0.05). The mean day for surgery was earlier in postmenopausal patients (p < 0.05). The radiological and laboratory findings were similar according to the menopausal status of patients. Among postmenopausal patients, the mean age at diagnosis, the duration of hospitalization, abscess size, and abscess volume were significantly higher in patients who also underwent surgery compared to those receiving only medical treatment (p < 0.05).

Conclusion: Postmenopausal patients with TOA differ from traditional abscesses regarding having more comorbidities, a history of extended IUD usage, and a higher possibility of occult malignancies. Postmenapausal patients are more tend to underwent surgeries, however individualized treatment strategies may required in clinical practice.

We report observations of five dwarf galaxies in the vicinity of the luminous S0 galaxy NGC 3115 performed with the Advanced Camera for Surveys on the Hubble Space Telescope. Their distances determined via the Tip of the Red Giant Branch are: 10.05 Mpc (UGCA 193), 9.95 Mpc (KKSG 17), 10.13 Mpc (2MASX-J0957-0915), 10.42 Mpc (2dFGRS-TGN218Z179), and 11.01 Mpc (KKSG 19). With their typical distance error of about 0.75 Mpc all the five dwarfs are consistent to be true satellites of the host galaxy NGC 3115 (10.2 ± 0.2 Mpc). Using the DESI Legacy Imaging Surveys we also found five new probable dwarf satellites of NGC 3115, as well as four new probable members of the neighboring group around NGC 3521 situated 3 Mpc away from the NGC 3115 group. Based on the radial velocities and projected separations of 10 dwarf companions, we derived the total (orbital) mass of NGC 3115 to be (4.89 ± 1.48) 1012
M
⊙. The ratio of the total mass-to-K luminosity of NGC 3115 is (50 ± 15) M
⊙/L
⊙, which is typical for the early-type luminous galaxies.

The Zwicky Transient Facility follow-up campaign of alerts released by the IceCube Neutrino Observatory has led to the likely identification of the transient AT2019fdr as the source of the neutrino event IC200530A. AT2019fdr was initially suggested to be a tidal disruption event in a Narrow-Line Seyfert 1 galaxy. However, the combination of its spectral properties, color evolution, and feature-rich light curve suggests that AT2019fdr may be a Type IIn superluminous supernova. In the latter scenario, IC200530A may have been produced via inelastic proton-proton collisions between the relativistic protons accelerated at the forward shock and the cold protons of the circumstellar medium. Here, we investigate this possibility and find that at most 4.6 × 10−2 muon neutrino and antineutrino events are expected to be detected by the IceCube Neutrino Observatory within 394 days of discovery in the case of excellent discrimination of the atmospheric background. After correcting for the Eddington bias, which occurs when a single cosmic neutrino event is adopted to infer the neutrino emission at the source, we conclude that IC200530A may originate from the hydrogen-rich superluminous supernova AT2019fdr.

The mirror-mode structures in the Martian magnetosheath that were observed by Mars Atmosphere and Volatile Evolution during 2015–2018 are analyzed statistically. It is found that most mirror-mode events occurred close to the bow shock. Morphological categorization based on skewness of the magnetic field shows that ∼46.57% of the observed mirror-mode events are peak-like, ∼40.25% are wave-like, and ∼13.18% are dip-like. The mirror-mode structures mostly saturate in a very short time after their formation near the bow shock, which is a result of the high temperature anisotropy and high plasma beta at this location. Carried downstream by the magnetosheath flow, the mirror-mode structures remain in nonlinear saturation states. Meanwhile, the dayside magnetosheath plasma largely deviates from marginal stability, which is a state commonly that is expected in the terrestrial magnetosheath. By flowline tracing in an MHD model, it is found the mirror structures can be divided into two groups: ∼80% of the events that are observed near the bow shock evolve less than 10 s in plasma with high temperature anisotropy and high plasma beta value, keeping in saturated states; the other 20% of the events evolve following a similar process to that at the Earth, undergoing morphology transition in response to the local plasma conditions. However, the dayside magnetosheath is largely in an unstable condition, which prevents the mirror-mode structures from fully evolving into the decaying phase. Our results suggest that energy dispassion through wave-particle interaction might not be sufficient to remove the free energy that is introduced by the solar wind–Mars interaction.

Efforts to discover and characterize habitable zone planets have primarily focused on Sun-like stars and M dwarfs. K stars, however, provide an appealing compromise between these two alternatives that has been relatively unexplored. Understanding the ultraviolet (UV) environment around such stars is critical to our understanding of their planets, as the UV can drastically alter the photochemistry of a planet’s atmosphere. Here we present near-UV and far-UV Hubble Space Telescope's Cosmic Origins Spectrograph observations of 39 K stars at three distinct ages: 40 Myr, 650 Myr, and ≈5 Gyr. We find that the K star (0.6–0.8 M
⊙) UV flux remains constant beyond 650 Myr before falling off by an order of magnitude by field age. This is distinct from early M stars (0.3–0.6 M
⊙), which begin to decline after only a few hundred megayears. However, the rotation–UV activity relation for K stars is nearly identical to that of early M stars. These results may be a consequence of the spin-down stalling effect recently reported for K dwarfs, in which the spin-down of K stars halts for over a gigayear when their rotation periods reach ≈10 days, rather than the continuous spin-down that G stars experience. These results imply that exoplanets orbiting K dwarfs may experience a stronger UV environment than thought, weakening the case for K stars as hosts of potential “super-habitable” planets.
Fast, High-fidelity Lyα Forests with Convolutional Neural Networks

Published: April 2022

Full-physics cosmological simulations are powerful tools for studying the formation and evolution of structure in the universe but require extreme computational resources. Here, we train a convolutional neural network to use a cheaper N-body-only simulation to reconstruct the baryon hydrodynamic variables (density, temperature, and velocity) on scales relevant to the Lyα forest, using data from Nyx simulations. We show that our method enables rapid estimation of these fields at a resolution of ∼20 kpc, and captures the statistics of the Lyα forest with much greater accuracy than existing approximations. Because our model is fully convolutional, we can train on smaller simulation boxes and deploy on much larger ones, enabling substantial computational savings. Furthermore, as our method produces an approximation for the hydrodynamic fields instead of Lyα flux directly, it is not limited to a particular choice of ionizing background or mean transmitted flux.
A Tale of Two Circularization Periods
Authors: Zanazzi J. J.
Published: April 2022

We reanalyze the exquisite eclipsing binary data from the Kepler and TESS missions, focusing on eccentricity measurements at short orbital periods to empirically constrain tidal circularization. We calculate a circularization period of ∼6 days due to nearly circular binaries with long orbital periods (“cold core”) but find many binaries with moderate eccentricities that circularize interior to only ∼3 days (“eccentricity envelope”). We show that these features are present in previous spectroscopic surveys. We also reaffirm the statistically significant difference between the eccentricity distributions of young (<1 Gyr) and old (>3 Gyr) binaries. Our work introduces new methods that have the potential to reconcile theoretical predictions with observations to empirically constrain tidal circularization.
Description of Tabanus rondoniensis (Diptera: Tabanidae), a new species of horsefly from the State of Rondônia, Brazil
Authors: Henriques Augusto , Krolow Tiago Kütter , Zamarchi Tallita , Camargo Luís
Published: April 2022

The genusTabanusLinnaeus has a worldwide distribution and is the richest in species; however, it is probably not monophyletic. In the Neotropical Region, its richness is certainly underestimated, mainly due to the large number of species and the absence of recent taxonomic revisions.

We describeTabanus rondoniensissp. n. from the State of Rondônia, Brazil, based on a conspicuous tabanid species possibly related to theT. nebulosusspecies group. Diagnosis, discussion and illustrations are also provided.

Published: April 2022

A new species of Leptostraca, Sarsinebalia agoensissp. nov., from Ago Bay, Japan is described from specimens found at a depth of 120 m. The new species differs from other known Sarsinebalia species as follows: the compound eye has three distal lobes; the anterior margin of the first antennal segment has one distal process covered with setae; and the lateral margin of pleopod 1 exopod bears 5–6 simple, robust spines. A taxonomic key to all species of Sarsinebalia is also provided.

Cyrtodactylus is the most diverse genus of the family Gekkonidae and the world’s third largest vertebrate genus. The number of species has increased more than fourfold over the last two decades. Indochina, especially Vietnam and Laos, has witnessed a surge in new species discoveries over the last three decades. The species number reported from Laos and Vietnam has remarkably increased from five in 1997 to 71 species in 2021. However, within the genus, several taxonomic issues have not yet been fully resolved. Based on recently collected samples from Laos and Vietnam, we conducted a comprehensive molecular review of Cyrtodactylus occurring in Laos and Vietnam. Our molecular analysis with support from morphological comparisons showed that C. thuongae is a junior synonym of C. dati and C. rufford is a junior synonym of C. lomyenensis. In total, 68 described species distributed in Laos and Vietnam are undisputed with strong support from both molecular and morphological evidence. On the other hand, the molecular analyses revealed that there are at least seven undescribed species in Vietnam and Laos, one in the C. angularis group, one in the C. chauquangensis, and five in the C. irregularis group. This number will likely increase significantly, as previous work suggested that the C. angularis and C. irregularis groups harbor three and six unnamed lineages, respectively. Based on survey gaps identified in our study, it is clear that additional new species will be discovered in poorly studied regions of central Vietnam and northern and southern Laos. As many species in the genus are facing high extinction risks, several undescribed populations might already be severely threatened by human activities in both countries. Therefore, urgent taxonomic research is needed before conservation assessments of newly discovered taxa can be undertaken to protect them from anthropogenic threats.
