THE LINGUISTIC CONSTRUCTION OF IDIOMS IN TV DRAMA: THE SIGNIFICANCE OF TEACHING IDIOMS TO IRAQI LEARNERS OF ENGLISH
Authors: Assi. Lect. Sahira Ahmed Mahmood  
Published: March 2023

As English is heavily idiomatic, this paper attempts to answer the question how Iraqi learners can better understand and speak English when interacting with native speakers of English from hearing and being exposed to constructed dialogue in TV drama. Hence, the paper has two focal points: the linguistic (semantic and syntactic) construction of idioms in dialogue scripted for the screen and the problems that Iraqi learners encounter in learning English idioms and fixed expressions. An idiom is the assigning of a new meaning to a group of words which already have their own meaning. Idioms can be easily identified with the familiar parts of speech. Thus, some idioms are clearly verbal in nature: "figure out/shy away from," an equally large number are nominal in nature: "feet of clay", many are adjectives: "butterflies in my stomach," and many are adverbial: "high and dry." These idioms which correlate with the familiar parts of speech can be called "lexemic idioms." The other most important group of idioms are of larger size. Often they are an entire clause in length: "have the guts," "have the stomach for," "to be caught between the rock and a hard place. As the English of advanced students, while grammatically, phonologically, and lexically correct, may sound rather bookish and pedantic to a native speaker. Iraqi learners have difficulties in understanding idioms for a number of reasons: idioms have figurative unpredictable meaning, distinctive cultural features, they exist in large numbers and thus difficult to memorize, lack of frequent use, and inadequate method of learning idioms. The study shows that learning idioms in the appropriate context of situation will result in learners' understanding and speaking better and more fluent English. The study hence not only contributes to the fields of linguistic stylistics and media studies, but also to applied linguistics and pragmatics, in particular through revising the concept and meaning of idioms.
The Core Progress of Staggered PRF Modulation Technique in MTI Radar
Authors: Tang Lei 
Published: March 2023

<p>For a long-distance guard radar, MTI filter usually employs low staggered pulse repetition frequencies (PRF) modulation technique to overcome blind speed and detect the targets at low altitude in the presence of clutter. For a given ratio of the maximum-to-the minimum period, we find that there exists an optimum stagger ratios construction criterion (OSRCC) which can guarantee the first null depth minimum, and the associated estimation formula containing variable has been derived successfully. In addition, based on more understanding to the properties of staggered PRF, we introduce a new stagger ratios optimization method that is much simple, efficient and flexible. In brief, this paper has thoroughly deconstructed this important basic technique in radar system. </p>
Audit on the Knowledge, Attitudes and Practice aboutthe Misuse of Antibiotics in Upper Respiratory Tract Infections in Children among Parents in Al-Najaf Province.
Authors: Baiee Hassan Alwan , Altufaily Yahiya , Hassan Worood Zaher 
Published: March 2023

Backgrounds: Upper respiratory tract infections are common in children. The cause of these infections are usually viral, but parents attitudes often contribute to inappropriate prescription of antibiotics, promoting antibiotic resistance, which is an important growing global health problem. In addition to that, lead to increase the burden of chronic diseases, rising costs of health services and the development of side effects (e.g. adverse gastrointestinal effects) which are more significant in children.
Objectives: identifying possible associated factors with antibiotic misuse among parents who attended primary health care in Al-Najaf province.
Methods: A cross-sectional study was carried out in Al-Najaf during the period of the first of March to the first of June 2014. Two primary health care centers were randomly selected and 431 fathers and mothers who attended these centers were inter viewed and randomly selected by systematic random sample technique, data collection were done twice weekly during the period of the study. Data was gathered through structured questionnaire which was used to identify different variables by face to face interview.
Results: There was positive significant association between mean knowledge score (11.09± 2.94) and mean attitude scores (13.87±3.59), between mean knowledge (11.09± 2.94) and mean practice score (8.77± 2.31) and between mean attitude scores (13.87±3.59) and mean practice score (8.77± 2.31) (p<0.001). The associated factors of AB misuse in children with URTI among Al Najaf parents being a young age parent (P=0.001), having low educational level(P<0.001), being a self-employed (P=0.001). And residence in a rural area (P=0.002) which are significantly associated to inadequate knowledge, inappropriate attitudes, and wrong practices.
Conclusions: This study has identified the main groups of parents that should be targeted in future interventionprograms. These groups are small age parents, those with low educational level, self-employed and those wholive in rural area.
Recommendation: Health education campaigns, medical staff education as well as public awareness campaignsare needed to explain the role of antibiotics in URTI treatment .And stronger legal restrictions should beintroduced on the selling of antibiotics in community pharmacies according to special guidelines recommendedby the ministry of health

The Effects of Currency Redesign 0n Vote Buying and the Quality of the Electoral Process in Ikere Local Government of Ekiti State
Authors: Omoyeni Tolulope Julius 
Published: March 2023

In an announcement made by the Central Bank of Nigeria governor on October 26, 2022, it was disclosed that new Naira notes would be introduced to replace the existing denominations of 200, 500, and 1,000 Naira notes. The redesign was scheduled to come into effect on Thursday, December 15, 2022 few weeks to the 2023 general elections. This research study examines the effects of the currency redesign on vote buying, quality and integrity of the electoral process in Ikere Local Government Area of Ekiti State. The population of study is 65,651 registered voters in the 11 wards of Ikere Local government. The study adopted a mixed-methods approach, using survey method, analysis of official election data, and non-participant observation, while a simple random sampling technique was used to choose three polling units each from the 11 wards, purposive sampling method was deployed to select 10 respondents each from the 33 selected poling units bringing the number of respondents to 330. Instrument of data collection was the Likert style questionnaire with 0.690 Cronbach Alpha reliability test. Simple percentage and Pearson correlation were two statistical tools deployed in the analysis of data derived from the field survey using Statistical Package for Social Sciences (SPSS). The findings of this study revealed that the introduction of the new currency had reduced the open buying and selling of votes, however, politicians still found alternative means to induce voters in the just concluded election in Ikere Local Government Area. The study recommends that Government especially the security agencies should intensify effort through impeccable intelligences to smoke out and prosecutes those involve in vote buying to serve as deterrence for future elections in order to promote transparency, fairness and improve the quality of the electoral process.

Published: March 2023

Abstract
The launch of NuSTAR and the increasing number of binary black hole (BBH) mergers detected through gravitational wave observations have exponentially advanced our understanding of BHs. Despite the simplicity owed to being fully described by their mass and angular momentum, BHs have remained mysterious laboratories that probe the most extreme environments in the universe. While significant progress has been made in the recent decade, the distribution of spin in BHs has not yet been understood. In this work, we provide a systematic analysis of all known BHs in X-ray binary systems (XBs) that have previously been observed by NuSTAR, but have not yet had a spin measurement made using the “relativistic reflection” method obtained from those data. By looking at all the available archival NuSTAR data of these sources, we measure 10 new BH spins: IGR J17454-2919 −

We discuss the implications of our measurements on the entire distribution of stellar-mass BH spins in XBs, and we compare them with the spin distribution in BBHs, finding that the two distributions are clearly in disagreement. Additionally, we discuss the implications of this work on our understanding of how the “relativistic reflection” spin measurement technique works, and discuss possible sources of systematic uncertainty that can bias our measurements.
Cover Your Basis: Comprehensive Data-driven Characterization of the Binary Black Hole Population
Authors: Edelman Bruce , Farr Ben , Doctor Zoheyr 
Published: March 2023

Abstract
We introduce the first complete nonparametric model for the astrophysical distribution of the binary black hole (BBH) population. Constructed from basis splines, we use these models to conduct the most comprehensive data-driven investigation of the BBH population to date, simultaneously fitting nonparametric models for the BBH mass ratio, spin magnitude and misalignment, and redshift distributions. With GWTC-3, we report the same features previously recovered with similarly flexible models of the mass distribution, most notably the peaks in merger rates at primary masses of ∼10M
⊙ and ∼35M
⊙. Our model reports a suppressed merger rate at low primary masses and a mass-ratio distribution consistent with a power law. We infer a distribution for primary spin misalignments that peaks away from alignment, supporting conclusions of recent work. We find broad agreement with the previous inferences of the spin magnitude distribution: the majority of BBH spins are small (a < 0.5), the distribution peaks at a ∼ 0.2, and there is mild support for a nonspinning subpopulation, which may be resolved with larger catalogs. With a modulated power law describing the BBH merger rate’s evolution in redshift, we see hints of the rate evolution either flattening or decreasing at z ∼ 0.2–0.5, but the full distribution remains entirely consistent with a monotonically increasing power law. We conclude with a discussion of the astrophysical context of our new findings and how nonparametric methods in gravitational-wave population inference are uniquely poised to complement to the parametric approach as we enter the data-rich era of gravitational-wave astronomy.
Chemodynamical Analysis of Metal-rich High-eccentricity Stars in the Milky Way's Disk
Authors: Lee Ayeon , Lee Young Sun , Kim Young Kwang , Beers Timothy C. , An Deokkeun 
Published: March 2023

Abstract
We present a chemodynamical analysis of 11,562 metal-rich, high-eccentricity halo-like main-sequence stars, which have been referred to as the Splash or Splashed Disk, selected from the Sloan Digital Sky Survey and Large Sky Area Multi-Object Fiber Spectroscopic Telescope. When divided into two groups, a low-[α/Fe] population (LAP) and a high-[α/Fe] population (HAP), based on kinematics and chemistry, we find that they exhibit very distinct properties, indicative of different origins. From a detailed analysis of their orbital inclinations, we suggest that the HAP arises from a large fraction (∼90%) of heated disk stars and a small fraction (∼10%) of in situ stars from a starburst population, likely induced by interaction of the Milky Way with the Gaia-Sausage/Enceladus (GSE) or another early merger. The LAP comprises about half accreted stars from the GSE and half formed by the GSE-induced starburst. Our findings further imply that the Splash stars in our sample originated from at least three different mechanisms: accretion, disk heating, and a merger-induced starburst.
Coronal Magnetic Fields Derived with Images Acquired during the 2017 August 21 Total Solar Eclipse
Authors: Bemporad A. 
Published: March 2023

Abstract
The coronal magnetic field, despite its overwhelming importance to the physics and dynamics of the corona, has only rarely been measured. Here, electron density maps derived from images acquired during the total solar eclipse of 2017 August 21 are employed to demonstrate a new technique to measure coronal magnetic fields. The strength of the coronal magnetic fields is derived with a semiempirical formula relating the plasma magnetic energy density to the gravitational potential energy. The resulting values are compared with those provided by more advanced coronal field reconstruction methods based on MHD simulations of the whole corona starting from photospheric field measurements, finding very good agreement. Other parameters such as the plasma β and Alfvén velocity are also derived and compared with those of MHD simulations. Moreover, the plane-of-sky (POS) orientation of the coronal magnetic fields is derived from the observed inclination of the coronal features in filtered images, also finding close agreement with magnetic field reconstructions. Hence, this work demonstrates for the first time that the 2D distribution of coronal electron densities measured during total solar eclipses is sufficient to provide coronal magnetic field strengths and inclinations projected on the POS. These are among the main missing pieces of information that have limited so far our understanding of physical phenomena going on in the solar corona.
