Code-Mixing Analysis in Speech Act Used by Classy FM Radio Announcer
Authors: Helmita Helmita 
Published: May 2021

This study uses sociopragmatic theory, especially regarding code-mixing in speech acts at opening an event, greeting the listeners, and talking to interviewees. The purpose of writing is to determine the form of code-mixing and explain the meaning of the code-mixing used by the radio announcer, whether it is entered into locus, illocution, or perlocution. This paper is divided into three stages. The first stage is to provide data using the listening method by listening to radio broadcasts followed by the recording method. At the analysis stage, the data obtained were analyzed using related theories. At the last stage, it is making the conclusions and suggestions.
In this research, the average Classy FM radio announcers use code-mixing in their speech acts when broadcasting. Apart from being influenced by the names of the programs that is titled in English, it is also influenced by the standardization of the words used by Classy FM itself. For example, to invite the listeners to keep listening, the term”keep in tune" is used. The term of Classy FM listeners refers to the term ”Classy People," and many other terms are used. Besides, it is also found that in one speech act, there are three types of actions that are included in it, namely the act of locus, illocution, and perlocution. Although there are also some data found only in the locus (speech acts to state something).

We look, in this paper, the reception of the althusserianism as bearer of a challenge to the social theory project’s, namely, the affirmation of the partial character of all possibility of unequivocal closure to the theoretical making. This damage was, certainly, thought provoking for authors of other theorical bases. We noticed, in the present elaboration, three paradigmatic responses that worked as a reaffirmation of a basilar point for their theoretical buildings. They were answers against elements, since the beginning, present in the althusserian critic: the theoretical anti-humanism, the anti-historicism and the normative anti-teleologism. We will analyze, for that matter, the approaches of Carlos Nelson Coutinho, E. P. Thompson and Ruy Fausto, exponents of each of the perspectives mentioned above.
Implementación y uso clínico de la radioterapia adaptativa. Informe del grupo de trabajo de radioterapia adaptativa de la Sociedad Española de Física Médica (SEFM)

Published: May 2021

La radioterapia adaptativa (Adaptive Radiation Therapy, ART) se puede definir como la modificación del plan de tratamiento administrado a un paciente durante el curso de la radioterapia para tener en cuenta los cambios en la anatomía.
La aplicación de ART supone un cambio en el proceso radioterápico que implica el uso de numerosos recursos adicionales, no estando implementada de forma general. Así, aun tratándose de una idea introducida hace más de 20 años, todavía a fecha de hoy son objeto de estudio muchos de los aspectos que definen la ART: la decisión de proceder a la nueva planificación del tratamiento, el momento óptimo para adaptar el plan, el umbral dosimétrico o anatómico que define la necesidad de adaptar y la identificación de los pacientes que realmente se beneficiarían de la adaptación del tratamiento.
Este informe del Grupo de Trabajo sobre ART de la Sociedad Española de Física Médica (SEFM) tiene como objetivo describir los principios de esta técnica, así como los elementos necesarios para su implementación.
Se exponen las dos estrategias principales atendiendo al momento de su aplicación: offline, para actuar ante los cambios progresivos que se observan durante el tratamiento, y online, para mitigar los cambios aleatorios.
Se revisa el estado actual de ART aplicado a la práctica clínica para diferentes localizaciones anatómicas.
Se describen algunos de los instrumentos clave para su implementación: los algoritmos de registro deformable (Deformable Image Registration, DIR), exponiendo las principales métricas de similitud, los métodos de optimización de la similitud, y los modelos de deformación utilizados, analizando las características de los algoritmos de los softwares más utilizados.
Además, dada la importancia que tiene conocer la incertidumbre adicional que introduce el uso de los algoritmos DIR (sobre todo cuando se utilizan para deformar la matriz de dosis absorbida) se dedica un apartado a la validación de estos algoritmos, incluyendo los resultados para los principales softwares comerciales disponibles actualmente.
Por último, se presentan unas recomendaciones a la hora de aplicar ART en la práctica clínica.
NEMESIS: Exoplanet Transit Survey of Nearby M-dwarfs in TESS FFIs. I.
Authors: Feliz Dax L. , Plavchan Peter , Bianco Samantha N. , Jimenez Mary , Collins Kevin I. , Villarreal Alvarado Bryan , Stassun Keivan G. 
Published: May 2021

Abstract
In this work, we present an analysis of 33,054 M-dwarf stars, located within 100 parsecs, via the Transiting Exoplanet Survey Satellite (TESS) full-frame images (FFIs) of observed sectors 1–5. We present a new pipeline called NEMESIS, developed to extract detrended photometry, and to perform transit searches of single-sector data in TESS FFIs. As many M-dwarfs are faint, and are not observed with a two-minute cadence by TESS, FFI transit surveys can provide an empirical validation of how many planets are missed, using the 30-minute cadence data. In this work, we detect 183 threshold crossing events, and present 29 candidate planets for sectors 1–5, 24 of which are new detections. Our sample contains orbital periods ranging from 1.25 to 6.84 days, and planetary radii from 1.26 to 5.31 R
⊕. With the addition of our new planet candidate detections, along with detections previously observed in sectors 1–5, we calculate an integrated occurrence rate of 2.49 ± 1.58 planets per star, for the period range ∈ [1, 9] days, and planet radius range ∈ [0.5,11] R
⊕. We project an estimated yield of 122 ± 11 transit detections of nearby M-dwarfs. Of our new candidates, 23 have signal-to-noise ratios >7, transmission spectroscopy metrics >38, and emission spectroscopy metrics >10. We present all of our data products for our planet candidates via the Filtergraph data visualization service, located at https://filtergraph.com/NEMESIS.

Abstract
To determine the importance of merging galaxies to galaxy evolution, it is necessary to design classification tools that can identify the different types and stages of merging galaxies. Previously, using GADGET-3/SUNRISE simulations of merging galaxies and linear discriminant analysis (LDA), we created an accurate merging galaxy classifier based on imaging predictors. Here, we develop a complementary tool, based on stellar kinematic predictors, derived from the same simulation suite. We design mock stellar velocity and velocity dispersion maps to mimic the specifications of the Mapping Nearby Galaxies at Apache Point (MaNGA) integral field spectroscopy (IFS) survey, and utilize an LDA to create a classification, based on a linear combination of 11 kinematic predictors. The classification varies significantly with mass ratio; the major (minor) merger classifications have a mean statistical accuracy of 80% (70%), a precision of 90% (85%), and a recall of 75% (60%). The major mergers are best identified by predictors that trace global kinematic features, while the minor mergers rely on local features that trace a secondary stellar component. While the kinematic classification is less accurate than the imaging classification, the kinematic predictors are better at identifying post-coalescence mergers. A combined imaging + kinematic classification has the potential to reveal more complete merger samples from imaging and IFS surveys such as MaNGA. We note that since the suite of simulations used to train the classifier covers a limited range of galaxy properties (i.e., the galaxies are of intermediate mass, and disk-dominated), the results may not be applicable to all MaNGA galaxies.
A Self-consistent, Time-dependent Treatment of Dynamical Friction: New Insights Regarding Core Stalling and Dynamical Buoyancy
Authors: Banik Uddipan , van den Bosch Frank C. 
Published: May 2021

Abstract
Dynamical friction is typically regarded as a secular process, in which the subject (“perturber”) evolves very slowly (secular approximation) and has been introduced to the host over a long time (adiabatic approximation). These assumptions imply that dynamical friction arises from the LBK torque with nonzero contribution only from purely resonant orbits. However, dynamical friction is only of astrophysical interest if its timescale is shorter than the age of the universe. In this paper we therefore relax the adiabatic and secular approximations. We first derive a generalized LBK torque, which reduces to the LBK torque in the adiabatic limit, and show that it gives rise to transient oscillations due to nonresonant orbits that slowly damp out, giving way to the LBK torque. This is analogous to how a forced, damped oscillator undergoes transients before settling to a steady state, except that here the damping is due to phase mixing rather than dissipation. Next, we present a self-consistent treatment that properly accounts for time dependence of the perturber potential and circular frequency (memory effect), which we use to examine orbital decay in a cored galaxy. We find that the memory effect results in a phase of accelerated, super-Chandrasekhar friction before the perturber stalls at a critical radius, R
crit, in the core (core stalling). Inside R
crit the torque flips sign, giving rise to dynamical buoyancy, which counteracts friction and causes the perturber to stall. This phenomenology is consistent with N-body simulations, but has thus far eluded proper explanation.
Le sans-abrisme à l’âge de la vieillesse
Authors: Grenier Amanda , Sussman Tamara , Cadenza Academic translations  
Published: May 2021

Le sans-abrisme à un âge avancé est en augmentation dans divers contextes internationaux. Bien que les médias et la littérature académique commencent à s’emparer de ce phénomène, les personnes âgées sont confrontées à un paradoxe : « hypervisibles » dans les cadres institutionnels et les lieux publics, tels que la rue et les refuges d’urgence, elles bénéficient cependant de peu de reconnaissance au sein des politiques publiques et des stratégies de lutte contre le sans-abrisme. S’inspirant des découvertes réalisées lors d’un projet de recherche ethnographique à Montréal (Québec), cet article engage une discussion sur l’exclusion sociale. Il s’ouvre sur la citation qui a suscité cet intérêt particulier, puis présente le contexte dans lequel est étudié le sans-abrisme des personnes vieillissantes. Il aborde ensuite les cadres conceptuels existants de l’exclusion sociale en gérontologie sociale et évalue la pertinence de ceux-ci pour la compréhension de ce type de sans-abrisme. Pour ce faire, il mobilise des domaines proposés par Scharf, Phillipson et Smith (2005), Grenier et Guberman (2009) et Walsh, Scharf et Keating (2017), ainsi que 40 entretiens qualitatifs menés lors d’une étude ethnographique CRSH de quatre ans portant sur le sans-abrisme. Cet article démontre en quoi le sans-abrisme des personnes vieillissantes est, comme l’a exprimé un participant et comme cela est manifeste dans un grand nombre de ces entretiens, une expérience d’exclusion sociale supplémentaire.
From Sully to Nightingale: Critical Thinking Through Esthetic Learning
Authors: Wiles Brenda , Enslein Terri 
Published: May 2021

Background:
Nursing faculty continually seek new teaching strategies to promote prelicensure nursing students' critical thinking. Students construct new knowledge through experience. Esthetic learning methodologies involve gaining knowledge and insight through emotive, firsthand experiences. The esthetic experience of watching a movie, coupled with reflective journaling, has been used with health care students to promote learning. However, little is documented in the literature on its use with nursing students or its influence on the formulation of critical thinking skills.

Method:

This descriptive qualitative study explored the impact of watching the movie,
Sully
, followed by structured reflective journaling on critical thinking of prelicensure nursing students.

Results:
Themes were identified which demonstrated students' insights into the components of critical thinking and expert thinking.

Conclusion:

Esthetic learning is a promising teaching approach that addresses multiple ways of knowing, thereby enhancing students' learning about critical thinking in a prelicensure education program.

Comparison of Clinical Performance of Ambu Aura40 Laryngeal Mask Airway with Classic Laryngeal Mask Airway for Spontaneous Ventilation during Elective Surgeries under General Anaesthesia
Authors: Raj Anusha , Kadni Reena R. , Zachariah Varghese K. 
Published: May 2021

Background:
Introduction of the laryngeal mask airway (LMA) has revolutionised the practice of anaesthesia. This study compares the clinical performance of Ambu Aura40 LMA with Classic LMA in anaesthetised spontaneously breathing patients in terms of its ease of use and side effects.

Patients and Methods:
In this prospective randomised controlled study, 176 patients were allocated to either the Classic LMA or Ambu Aura40 LMA group according to a pregenerated block randomisation number sequence with concealment method. The allocated LMA was placed under general anaesthesia without muscle relaxant. The time and ease of insertion were noted in addition to any adverse events.

Results:
It was observed that Ambu Aura40 LMA and the Classic LMA were positioned successfully in the first attempt in 94% and 81% of patients respectively. The Ambu Aura40 LMA was placed in <12 s in 52% of patients, whereas only 2% of patients in the Classic LMA group could have the device placed within 12 s. Ninety-four percent of Classic LMA and 48% of Ambu Aura40 LMA were placed between 12 and 16 s, respectively. Statistically, a significant difference was noted with time and ease of insertion in between the groups.

Conclusion:
Ambu Aura40 LMA is better in terms of ease of insertion, with reduced time for insertion and lesser incidence of postoperative sore throat in comparison with Classic LMA.
Prevalence of low Back Pain among Street Cleaners in Northeastern Nigeria
Authors: Yunoos Adetoyeje Oyeyemi , Dankoly Usman Sani 
Published: May 2021

Context:
Street cleaners assume bending and twisting positions for a long period while on the job, making them to be susceptible to low back pain (LBP).

Aims:
This study was aimed at determining the prevalence of LBP among street cleaners in North-eastern Nigeria.

Settings and Design:
Sample of convenience was to recruit 381 participants who were street cleaners working within Maiduguri Metropolitan Council.

Subjects and Methods:
A conveniently sampled participants (n = 381) completed sociodemographic form, Nordic LBP Questionnaire and LBP risk factors form. Descriptive statistics were used to summarise the data, and Chi-square statistics were used to explore the differences in LBP prevalence by sociodemographics.

Results:
The present study shows a 12-month LBP prevalence rate of 78.2% and a crude point (7 days) prevalent rate of 55.1% among the workers, and this condition tend to occur more frequently among those in the age group between 58 and 67 years than their counterparts in the lower age groups (P = 0.001). Male cleaners tend to report LBP more frequently than their female counterparts (P = 0.011), and those with primary or qur'anic education also reported LBP more frequently than their counterparts with secondary or tertiary education (P = 0.046). Performing the same task over and over and working in the same position for long periods were the most frequently chosen risk factors pre-disposing the workers to LBP on their job.

Conclusions:
The present study identified the needs for workers ergonomic education and employers' consideration for ergonomically fit tools, as potential solution to addressing LBP as an occupational hazard among the workers.
Work and School Absenteeism in Inflammatory Bowel Disease Patients in Jeddah, Saudi Arabia
Authors: Mosli Mahmoud H. , Alamri Abdullah A. , Saadah Omar I. 
Published: May 2021

Background:
Inflammatory bowel disease (IBD), which can have a considerable effect on quality of life, productivity and performance, is typically diagnosed during periods of life in which patients have academic and career-related responsibilities.

Objective:
The objective of the study was to determine the effect of IBD symptoms on work and school absenteeism in patients from Saudi Arabia.

Patients and Methods:
This cross-sectional survey included patients diagnosed with IBD, aged >8–60 years, at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. The validated 32-question IBD quality-of-life questionnaire was used to elicit information regarding quality of life and another 9-question validated questionnaire was used to assess work and school absenteeism. A logistic regression analysis was used to identify possible determinants of absenteeism.

Results:
A total of 123 IBD patients were included, with a 1:1 male-to-female ratio. The median age at presentation was 26 years (range: 8–59 years), 56.9% had Crohn's disease, and 43.1% had ulcerative colitis. Further, 58 (47.2%) were employed, 49 (39.8%) were students and 16 (13%) were unemployed. Forty-seven (43.9%) participants reported absenteeism: 26 were employees (55.3%) and 21 were students (44.7%). A binary logistic regression analysis identified IBD subtype (P = 0.006) and the presence of perianal disease (P = 0.028) as clinical predictors for absenteeism from school or work. A feeling of abdominal pain (P = 0.015), fatigue (P = 0.015) and difficulty taking part in social engagements (P < 0.001) were also significantly associated with absenteeism.

Conclusions:
A sizeable proportion of the participants reported absenteeism owing to the effects of IBD. IBD subtype, perianal disease, presence of ongoing abdominal pain, fatigue and difficulty in social engagement were strongly associated with nonattendance.
Case Report: Clonorchis sinensis Infection Associated with Eosinophilic Pneumonia
Authors: Reddy Archana K. , Chakrabarty Melony , Liu Ying , Cohen Stuart H. , Maniar Archana H. 
Published: May 2021

Abstract.Clonorchis sinensis, a trematode prevalent in East Asia, causes hepatobiliary infection. Exposure typically occurs through ingestion of raw or undercooked fish containing the encysted larval form of the parasite. Extrahepatobiliary disease has not commonly been described. In this case report, we describe an unusual case of C. sinensis infection associated with eosinophilic pneumonia. A middle-aged man from China presented with subacute cough and was found to have a bilateral diffuse eosinophilic pneumonia with associated peripheral eosinophilia. Stool microscopy revealed C. sinensis eggs, and the patient improved after treatment with prednisone and praziquantel. Pulmonary clonorchiasis should be considered in patients with eosinophilic pneumonia from areas highly endemic for this pathogen.

Abstract.Little is known about the effect of helminth infections on the natural gynecological and pregnancy course. Our goal was to assess the relationship between Wuchereria bancrofti and hookworm (HW) infections with pregnancy course and outcome in a group of 82 women living in a rural area of the Democratic Republic of the Congo. Demographics and information on gynecological and obstetrical histories were collected retrospectively with standardized questionnaires. Wuchereria bancrofti and HW infections were diagnosed using a filarial antigen-detection test and the Kato–Katz method, respectively. Analyses consisted of multivariable logistic regressions adjusting for age, number of deliveries, and history of anthelmintic treatment (HAHT). The median age of study participants was 35 (interquartile range [IQR]: 30–44) years, and the median number of deliveries was five (IQR: 3–7). Wuchereria bancrofti and HW infection rates were 44.5% and 43.3%, respectively. Filarial antigenemia and HW infection were not significantly associated with the number of deliveries. The proportions of women with a history of pregnancy resulting in neonatal death, miscarriage, premature birth, and postpartum hemorrhage were 56%, 44%, 23%, and 36%, respectively. History of pregnancy associated with neonatal death was less frequent in women with HAHT, tended to be more frequent in women with filarial antigenemia, and was not associated with HW infection. None of the three other pregnancy events studied (miscarriage, premature birth, and postpartum hemorrhage) were associated with filarial antigenemia or HW infection. The positive association found between HAHT and lower risk of neonatal death warrants investigation in larger groups of women.
