Recuperación de pequeñas y medianas empresas en concurso a través de sociedades cooperativas y su contribución a la «responsabilidad social concursal»
Authors: Pastor Sempere Carmen
Published: March 2021

Resulta altamente preocupante como en un país como España cuyo tejido empresarial se compone de PYMES en niveles muy superiores al de otros países, las medidas de reestructuración empresarial y saneamiento nunca son diseñadas por el legislador pensando en estas PYMES; al contrario, incluso las de tamaño medio acaban «muriendo a lo largo» del procedimiento concursal, abocándolas a una irremediable liquidación. Ante este problema no resuelto por el legislador y una recesión económica que no tiene fin, las sociedades cooperativas están llamadas a desarrollar un papel activo como protagonistas de procesos de reestructuración y recuperación empresarial. Para ello, contamos con la experiencia de nuestra ya vieja reconversión industrial y con la de países, como la República de Argentina, donde la recesión dio lugar al nacimiento de fenómenos sociales espontáneos en los que los trabajadores han protagonizado un movimiento de resistencia económica, conocido como «Movimiento Nacional de Fábricas Recuperadas» caracterizado en la mayoría de las ocasiones, por ser los trabajadores quienes lograron comprar las instalaciones de la empresa concursada y continuaron la explotación a través de una sociedad cooperativa. En este breve trabajo se tratará esta posibilidad desde el procedimiento que diseña nuestra Ley Concursal y su contribución en lo que podríamos denominar como una incipiente «Responsabilidad Social Concursal».

Cooperativas y responsabilidad social empresarial
Authors: Martínez Charterina Alejandro
Published: March 2021

Las cooperativas naturalmente, es decir, por su propia identidad, asumen un compromiso de responsabilidad social en medio de un conjunto de empresas, mayoritariamente capitalistas, que pueden llegar a ese compromiso, en el mejor de los casos, cuando no interesadamente, de forma voluntaria.

Ley 6/2013, de Cooperativas de Cantabria: contenido y oportunidad para el desarrollo de la economía social
Authors: Gadea Enrique
Published: March 2021

Con la LCCANT se pretende ofrecer una regulación respetuosa con el modelo de verdadera sociedad cooperativa y, al mismo tiempo, introducir los instrumentos necesarios, no sólo para que las cooperativas puedan superar una etapa de crisis sino para que la organización cooperativista pueda ocupar un papel relevante dentro de la actividad económica cántabra. Sin embargo, aprobar una legislación adecuada es sólo el primer paso; una vez aprobada la norma empieza el verdadero reto. Entonces, el Gobierno regional deberá dotarse de una estructura administrativa capaz de ofrecer servicios y soluciones al mundo cooperativo y apostar, de forma decidida, por la divulgación del ideario cooperativo y por la promoción de las sociedades cooperativas como fórmula ventajosa respecto a otras formas jurídicas, favorecedora del autoempleo.

La cooperativa en el nuevo constitucionalismo latinoamericano. Probables contribuciones al perfeccionamiento de su regulación constitucional en Cuba
Authors: Rodríguez Musa Orestes
Published: March 2021

El objetivo de este trabajo es sistematizar los rasgos que caracterizan la regulación de la cooperativa en el nuevo constitucionalismo latinoamericano y que, en tal sentido podrían contribuir al perfeccionamiento del magno texto cubano. Para ello se comienza explicando el origen histórico y las tendencias de la constitucionalización de la cooperativa, así como los aspectos que —a juicio del autor— debería contener dicha constitucionalización. Sobre esta base se valoran, en un segundo momento, las limitaciones de la cooperativa en la Constitución socialista cubana. Por último, se identifican en tres de los textos representativos del nuevo constitucionalismo latinoamericano (Venezuela, Ecuador y Bolivia), aquellos elementos que podrían contribuir al perfeccionamiento de la regulación constitucional de la figura en Cuba.

El régimen fiscal cooperativo como instrumento de política económica
Authors: Calvo Vérgez Juan
Published: March 2021

El presente estudio tiene por objeto analizar la trascendencia que en la actualidad adquiere el régimen fiscal cooperativo como instrumento destinado a reforzar el papel de las cooperativas en el desarrollo de la actividad económica. Dicho régimen se revela en la actualidad como insuficiente, no habiéndose aprovechado la reciente Reforma Tributaria para reforzar el mismo. Y ello sin perjuicio de reconocer la trascendencia del papel desempeñado hasta la fecha por las distintas modalidades de sociedades cooperativas en los ámbitos relativos a la creación de empleo y al desarrollo tejido empresarial. Asimismo se subrayan otras actuaciones pendientes tales como la necesidad de mejorar la financiación de los socios y, en definitiva, reforzar la formación y difusión del cooperativismo.

El modelo cooperativo y el nuevo enfoque del desarrollo territorial: elementos de convergencias y potenciales sinergias
Authors: Gómez García Jesús María
Published: March 2021

El nuevo enfoque del desarrollo territorial «desde abajo», basado en procesos de carácter endógeno y base local, se fundamenta en la participación de los agentes económicos y sociales en los procesos transformadores del territorio para asegurar mayor impacto económico y social. El cooperativismo supone un modelo con elevada capacidad para potenciar la actividad económica del territorio, generar empleo de calidad, favorecer la cultura emprendedora local e impulsar la mejora del nivel y la calidad de vida de la comunidad, fijando la población al territorio. Entre ambos enfoques existen convergencias y potenciales sinergias. Las cooperativas, en particular las agrarias, por su fuerte vinculación social y anclaje territorial, constituyen una forma empresarial clave para el desarrollo territorial en el medio rural.

Observaciones críticas al vigente marco legal de las sociedades cooperativas de Andalucía
Authors: Vargas Vasserot Carlos
Published: March 2021

El 23 de diciembre de 2011 se promulgó la Ley 14/2011 de Sociedades Cooperativas Andaluzas. Esta Ley, de tercera generación, tras las de 1985 y 1999, junto a su Reglamento de desarrollo aprobado por el Decreto 123/2014, configuran el marco legal de las cooperativas que desarrollen principalmente su actividad societaria en Andalucía, Comunidad Autónoma con mayor número de cooperativas de España. El nuevo marco legal fue concebido por el legislador andaluz como obligada adaptación a la lógica evolución del entorno económico y normativo en que se insertan las cooperativas, pero también explicada como necesaria reforma interna, como evolución del propio tipo societario. En ambas vertientes son numerosos e importantes los cambios que se introducen respecto a la legislación anterior, situándose además en vanguardia en cierta materia respecto al resto de leyes cooperativas autonómicas, lo que justifica la elaboración de un análisis crítico del contenido del nuevo marco legal de las cooperativas de Andalucía.

Aminomethylated Hydroxinaphthalenes: Synthesis and Application
Authors: Slitikov P.V. , Evdokimenkova Yu.B.
Published: March 2021

The analysis of the literature is carried out and the results of the synthetic approaches to the aminomethylation of hydroxy derivatives of naphthalenes developed over the past 20 years are presented. Most of the described aminomethylation processes proceed as Mannich aminomethylation or, as a special case of a similar condensation --- aminobenzylation according to Betti. The results of all studies are grouped according to the nature of the amine used in the synthesis: primary, secondary, tertiary. Most of the examples were considered for 2-naphthol, however, as the analysis of literature data shows, similar methods are applicable to 1-naphthol and dihydroxynaphthalenes with different positions of OH groups in the ring --- often only the yields of the target product differ. Both the classical methods for the preparation of Mannich and Betti bases using the carbonyl component (formaldehyde, benzaldehyde and its derivatives, respectively) and special cases of synthesis, in which condensation is carried out by means of halogen derivatives, substituted azacrown ethers, etc., are presented. Particular attention is paid to the use of various catalysts and activators, allowing to significantly simplify the synthetic procedures and increase the yields of target compounds. The main fields of application of aminomethylated derivatives of hydroxynaphthalenes are presented
Setting up Experiments for Analyzing Disturbances of the Head Shock Wave Due to the Presence of Particles in the Supersonic Flow
Authors: Gerasimov S.I. , Erofeev V.I. , Kosyak E.G.
Published: March 2021

The research in the field of devices and methods of experimental physics includes, in particular, the creation of installations for conducting experiments in the physics of multiphase nonequilibrium flows. Multiphase flow around bodies is of significant importance in various fields of technology, for example, in power engineering, contact visualization methods, aerosol technologies, in the application of various coatings, etc. In the high-speed two-phase flow around bodies, the physics of particle collisions with the surface and the interaction of flying particles with the head shock wave play an important role. Most of the experiments in this area, including the passage of the model through the zone of rain, snow, dust, cooled clouds, etc., are carried out in the reverse setting. In this case, the model is fixed, and the flow is made by one or another high-enthalpy aerodynamic installation. This approach does not correspond to the initial stage of the interaction formed before the entrance to the zone of the two-phase medium, between the head shock and the incident particle. Nevertheless, for some approaches, it is of interest to visually confirm the possibility of an oncoming particle being ejected at a supersonic speed by the front of the head shock wave and to see the deceleration of the model from the shadow pattern with a change in the Mach line. The paper considers a direct ballistic experiment which by shadow visualization tests the possibility of cavern formation near a body crossing the trajectory of the atmosphere saturated with dust particles

The term "idiopathic hydrocephalus" in adults is a broader concept that includes larger spectrum of patients compared to "idiopathic normotensive hydrocephalus". It includes both young and elderly patients with various forms of the disease, patients with various levels of obstruction. Th ere is no general classification and general approach to treat patients with such a pathology. Endoscopic triventriculostomy in idiopathic aqueductal stenosis and cerebrospinal fluid shunting after a positive test of cerebrospinal fluid (tap test) evacuation in idiopathic normotensive hydrocephalus are proved to be effective. In patients with other forms of cerebrospinal fluid pathway obstruction, treatment approach is represented by the opinions of some surgeons. At the same time, most surgeons consider the use of cerebrospinal fluid shunting operations to be effective and justified, and they use endoscopic techniques as an option for examining ventricular system and for performing auxiliary manipulations. The high frequency of various complications of bypass surgery and slightly lower efficiency of endoscopic operations indicates the need to systematize patients; to improve selection criteria and to expand the indications for the use of endoscopic surgical techniques.

The aim of the research is to analyze indicators and structure of infant mortality in Krasnoyarsk Territory for the period from 2014 to 2018. Material and methods. Th e article studies indicators of population mortality and fertility, infant mortality in Krasnoyarsk Territory for fi ve-year period from 2014 to 2018. Th e analysis of the results obtained is carried out in comparison with other constituent entities of the Russian Federation and with the country in general. Newborns morbidity rates in Krasnoyarsk Territory over a five-year period were studied in comparison with the data for the Russian Federation during 2017 and 2018. Results. The study revealed the excess of mortality over births in the region by 2018, with the coeffi cient 0.7 for 1000 population. It was found that in the period from 2014 to 2018 there is a decrease in infant mortality rate in the Russian Federation by 31.1 %; by 21.8 % in the Siberian Federal District; by 33.7 % (from 8.8 to 5.5 for 1000 alive births) in Krasnoyarsk Territory. The main causes of infant mortality in the territory are: conditions occurring in perinatal period, external causes and congenital anomalies (malformations). Decrease of infant mortality in the territory is primarily determined by the decrease in the number of deaths among children under 1 year of age due to the above-mentioned causes. Despite the annual decrease in infant mortality rate, on average, every third death occurs in the first 28 days of a child’s life. When studying the morbidity of newborns, one can mark a steady decline of the indicator both in the Russian Federation and in Krasnoyarsk Territory. At the same time, every year more than 80 % of absolute number of sick newborns falls on full-term babies. Conclusion. Th e results obtained during the study indicate a decrease in infant mortality rate over the study period. Th e study of indicators of infant mortality and morbidity in newborn children is fundamental in the fi eld of maternal and child health. Pediatricians need to pay special attention when examining newborns and children of the first year of life; they should timely identify pathological conditions and diseases, which will help reduce the risk of complications, chronic diseases, and, deaths.

Focal Artefacts in Skeletal Scitigraphy
Authors: Mironov S. P. , Vasilenko E. I. , Karalkina M. A. , Bugriy M. E. , Sergienko V. B.
Published: March 2021

Objective: to clarify and systematize the causes that can induce focal artefacts in skeletal scintigraphy with 99mTc-pyrophosphate (PyP), their semiotics, principles and methods of differentiation from bone pathology.

Material and methods. Results of skeletal scintigraphy from 1568 patients were analyzed. Scanning in “whole body” mode started in 3 hours after 740 MBq of radiotracer activity intravenous administration, and performed in anterior and posterior projections in continuous table motion mode at rate of 12 cm per minute. Single photon emission computed tomography/computed tomography was additionally performed when necessary.

Results. Focal artifacts were detected in 40 patients (2.55%) and were divided into “cold” and “hot” according to the nature of the bone system changes they simulated. “Cold” spots (n = 29) were the result of the shielding effect of metal accessories (n = 10), implants, endoprostheses (n = 18), and barium suspension residues in the large intestine (n = 1). “Hot” spots (n = 11) mimicking metastatic lesion of bone structures were the results of the projection effect of extraosseous uptake of 99mTc-PyP (n = 9) or urinary contamination (n = 2). “Hot” spots in the projection of the upper pole of the kidney (n = 5) could be the result of both calicostasis (n = 3) and injury of the adjacent rib (n = 2). The high uptake of 99mTc-PyP in thyroid nodule (n = 3) simulated a “hot” spot in the lateral part of the cervical vertebra. Abnormal accumulation of 99m Tc-PyP in the nipple-areola areas of the breast was projected onto the posterior segments of the ribs. Urinary contamination imitated focal pathology of the pelvic bones. To differentiate the focal pathology of the ribs and calicostases, the patients were examined in the standing position. The “mask in” program was used to clarify the localization and projection correspondence of “hot” foci.

Conclusion. Analysis of focal artefacts formation causes in skeletal scintigraphy contributes to an adequate assessment of the data obtained, allows to choose the necessary method for their diagnosis and to avoid false results of osteoscintigraphy.
Prospective Assessment of mrTRG System Used for Determining the Efficiency of Neoadjuvant Chemoradiotherapy in Patients with Rectal Cancer
Authors: Berezovskaia T. P. , Dayneko Ya. A. , Nevolskikh A. A. , Ivanov S. A. , Kaprin A. D.
Published: March 2021

Background. Evaluation of the therapeutic effect of neoadjuvant chemoradiotherapy (nCRT) for rectal cancer (RC) is of prognostic value and allows to individually plan the type and extent of further surgical intervention. One of the most promising methods of MRI evaluation is magnetic resonance tumour regression grade (mrTRG) system. However, the reliability and safety of this method must be confirmed by the results of clinical trials and practical application.

Objective: to analyze our experience in the prospective use of mrTRG system and evaluate the additional contribution of diffusion-weighted images (DWI) to its diagnostic efficiency.

Material and methods. The mrTRG values were determined in 125 (including 30 with DWI) patients with locally advanced RC who received combined treatment with nCRT in Tsyb Medical Radiological Research Centre from 2015 to 2019. The obtained data were compared with the modified pathologic response based on Lushnikov’s definition, and the diagnostic parameters of differentiation of patients responding and nonresponding to nCRT were calculated.

Results. When the mrTRG system was used without DWI, the following sensitivity and specificity values as well as positive and negative predictive values were obtained: 75%, 60%, 70% and 67%, respectively, with DWI – 87%, 87%, 87% and 87%, respectively.

Conclusion. A prospective evaluation of the result of nCRT using the mrTRG system has moderate accuracy for stratification of patients responding and non-responding to nCRT, which requires the use of additional criteria for MRI scores to select patients who may receive less aggressive surgical treatment. Despite the small number of patients with DWI, we obtained higher values of the diagnostic parameters. In this regard, we consider it appropriate to use DWI when assessing the treatment response.

Game-Based Learning and Assessment for History Education
Authors: Lee Woo Hyun , Park Sang Yong , Lee Won Hyung
Published: March 2021

Regardless of country and age, the importance of history education is always being emphasized. Although the importance of history education is being emphasized in Korea, there are many difficulties in getting students to understand history properly through school classes alone, and it is also difficult to attract students to participate in classes. The effectiveness of education using games has been proven 20 years ago, and the demand for game-based education is gradually increasing in the current education world, which is becoming more open. In this paper, based on the effects proven through research on the existing game-based education, the improvement of historical thinking ability, experiential history learning, and the problems of game-based education introduced in the ESN report and the discomfort of teachers who participated in the education were improved. A plan was suggested to select and use games suitable for basic education. In this thesis, we selected a history game with a clear historical and periodic background and without distortion of history, and experimented with teaching using games focusing on historical thinking and empirical history learning. The learning achievement of textbook-based education was compared.
Forecasting High-Frequency Financial Time Series: An Adaptive Learning Approach With the Order Book Data
Authors: Yang Parley Ruogu
Published: March 2021

This paper proposes a forecast-centric adaptive learning model that engages with the past studies on the order book and high-frequency data, with applications to hypothesis testing. In line with the past literature, we produce brackets of summaries of statistics from the high-frequency bid and ask data in the CSI 300 Index Futures market and aim to forecast the one-step-ahead prices. Traditional time series issues, e.g. ARIMA order selection, stationarity, together with potential financial applications are covered in the exploratory data analysis, which pave paths to the adaptive learning model. By designing and running the learning model, we found it to perform well compared to the top fixed models, and some could improve the forecasting accuracy by being more stable and resilient to non-stationarity. Applications to hypothesis testing are shown with a rolling window, and further potential applications to finance and statistics are outlined.

Objective. To assess the incidence of influenza in the epidemic season 2018/19 and to analyze severe cases that required extracorporeal membrane oxygenation (ECMO). Patients and methods. A total of 5,939 patients diagnosed with influenza and acute respiratory viral infections (ARVIs) were treated in S.P.Botkin Clinical Hospital for Infectious Diseases of Saint Petersburg in 2018–2019. The highest incidence was observed in the late January – early February. We tested 2,527 patients (42,5%) using polymerase chain reaction (PCR); of them, 1,014 patients (40,1%) were PCR positive for influenza. The vast majority of them (99.3%) were infected with influenza A. One hundred and thirty patients required treatment in the intensive care unit (ICU) (2.2%; 95% CI 1.8%; 2.6%). Results. Severe forms of the disease were primarily caused by influenza H1N1. Respiratory failure was treated by oxygen therapy in 81.7% of patients, artificial ventilation in 15.3% of patients, and ECMO in 3 patients (2.9%; 95% CI 0.6%; 8.5%). Conclusion. Approximately 0.01% to 1.6% of patients admitted to a hospital for infectious diseases with influenza or ARVI during the epidemic season require ECMO.

Objective. To evaluate the socioeconomic impact of COVID-19 in Rostov region. Material and methods. This article focuses on social and economic aspects of COVID-19. By estimating direct medical costs and gross domestic product (GDP) losses (sick leave days), we assessed the economic damage caused by the pandemic in Rostov region. When calculating direct medical costs, we considered per-case costs of completed outpatient and inpatient treatment and costs of laboratory testing (identification of coronavirus). When calculating the costs associated with paid sick Rostov region in 2020. Results. We found that COVID-19-associated direct medical costs and GDP losses (sick leave days) were 3,174,344,917.04 RUB. Almost half (42.7%) of direct medical costs were spent on outpatient treatment. GDP losses were 1,014,047,274.24 RUB. Conclusion. In addition to the direct impact on the health of vulnerable individuals, current pandemic will inevitably cause longterm socioeconomic consequences for both people and the economy. The assessment of the socioeconomic impact of COVID-19 is important to develop effective preventive and anti-epidemic measures, as well as to make optimal management decisions.

Published: March 2021

There is still an urgent need for accurate monitoring of the epidemiological situation of hepatitis C virus (HCV), its early diagnostics, broad access to treatment, and effective follow-up. Objective. Тo develop a model allowing the estimation of disease burden of hepatitis C in Chelyabinsk region, prognosis of the epidemiological situation, and planning of necessary measures to achieve the strategy goals of WHO by 2030. Materials and methods. We have developed a dynamic model of disease progression for quantitative assessment of HCV burden by liver disease stages in 1950–2030 using Microsoft Excel. This model was similar to that used in previous studies. Results and discussion. Our model demonstrated that total number of patients with chronic hepatitis C in Chelyabinsk region will continue to grow and reach 125,000 patients by 2030, if the approach to the diagnosis and treatment remains unchanged. Approximately 5,300 new cases of chronic hepatitis C will be registered every year. Alterations in the approach to HCV therapy (increased number of patients on treatment, therapy initiation regardless of liver fibrosis stage) along with some additional measures will ensure the achievement of key WHO targets by 2030. Conclusion. The achievement of WHO targets in Chelyabinsk Region by 2030 appears possible, but it requires significant resources and optimization of existing approaches to the diagnosis and treatment of HCV infection in the region.

The Variability of Pelvic Obliquity Measurements in Patients with Neuromuscular Scoliosis
Authors: Karkenny Alexa J. , Magee Lacey C. , Landrum Matthew R. , Anari Jason B. , Spiegel David , Baldwin Keith
Published: March 2021

Background:

Pelvic obliquity (PO), or pelvic alignment in the coronal plane, is an important radiographic parameter to indicate fusion levels and judge success of scoliosis correction in patients with neuromuscular scoliosis. There are multiple commonly used techniques to measure PO that have good to excellent interrater and intrarater reliability, but these different methods yield inconsistent values when used on the same radiograph. This study evaluates the inconsistency in the magnitude of PO measurements for patients with neuromuscular scoliosis among 5 common measurement techniques.

Methods:

Radiographs of 63 patients with neuromuscular scoliosis were evaluated by 5 raters. Each rater measured PO on each radiograph using the Osebold, O’Brien, Allen and Ferguson, Lindseth, and Maloney techniques. Patients were divided into 2 cohorts based on coronal balance or imbalance. Interrater and intrarater analyses were performed using a 2-way random effects model to calculate absolute agreement. The mean difference in PO between all possible pairs of the techniques was compared using a 2-tailed t test.

Results:

The Maloney and Osebold techniques demonstrated excellent interrater reliability, and the Maloney, Osebold, and O’Brien techniques demonstrated excellent intrarater reliability. Significant differences in PO measurement were found in 6 of the 10 comparisons for the balanced spines and 8 of the 10 comparisons for the unbalanced spines. Variability in measurement was captured by best-fit lines, which demonstrated greater dispersion between the means for the Osebold and Maloney techniques in the unbalanced spines than in the balanced spines.

Conclusions:

To our knowledge, this study is the first to evaluate mean differences in magnitude of PO among common measurement techniques while accounting for coronal imbalance. Although there is no gold standard for measuring PO, the Maloney and Osebold techniques are the most consistent. This study suggests that those 2 techniques can be used interchangeably when the spine is coronally balanced, but the Osebold technique becomes more inconsistent than the Maloney technique when coronal imbalance exceeds 2 cm.

Clinical Relevance:

This information is relevant to surgeons using PO to plan fusion levels and striving for objective ways to judge correction intraoperatively as well as for researchers compiling PO data from multiple centers or studies.
Arthroscopic Latarjet Procedure

» The proposed advantages of the arthroscopic approach in the Latarjet procedure for shoulder dislocation include improved visualization for accurate positioning of the coracoid graft, the ability to address any associated intra-articular pathologies, and the diminished potential for the formation of postoperative scar tissue and stiffness associated with an open procedure.

» Young age, the presence of glenoid and/or humeral bone loss, a history of dislocation, a history of failed arthroscopic stabilization surgery, and an active lifestyle are all associated with recurrent dislocation and are relative indications for an osseous augmentation procedure.

» Both the open and arthroscopic Latarjet procedures result in substantial improvements in patient function, with comparable rates of recurrent instability and complication profiles.

Authors: Tong Lien Thi My
Published: March 2021

Plenty of meticulous research has been conducted to investigate the entire process for implementing group activities in language classrooms. Nevertheless, few detailed empirical investigations have been pursued in the sub-area of what influences the participation of English-as-a-Foreign-Language (EFL) students in group discussions. Thus, the present study was conducted to examine the elements impacting the group-work participation of first-year EFL students at University of Languages and International Studies (ULIS), Vietnam National University (VNU). Ten EFL freshmen and four teachers of English participated in the study over a four-week period by attending semi-structured interviews. The findings highlighted a variety of elements discouraging the learners’ participation related to themselves, pedagogy, and culture and also revealed internal elements as the most significant.
Politeness Strategy in Shanghai Knights Film
Authors: Ernovilinda Ernovilinda
Published: March 2021

Language is a communication tool for every human being and is used  to convey ideas, messages, intentions, feelings, opinions to others or even to meet daily needs. Intercultural communication is a communication that frequently occurs in the community. Pragmatics is a branch of linguistics that discusses aspects of language as a communication tool. When combined with culture, intercultural communication that occurs in society can be understood. In order for a speaker's language to be accepted in a society, he needs to fully understand the rules that apply in that society, including an understanding of the appropriate  use of certain language functions or speech acts. There is a close relationship between pragmatics and the concept of politeness. Politeness is fundamental in pragmatics because this is a universal phenomenon in the use of language in social contexts. The focus of this research is to identify the politeness strategies used by the two main characters in the Shanghai Knights film, Chon Wang and Roy O'Bannon, and analyze them in terms of the cultural background of the two main characters. This is a qualitative descriptive study. The results show that the politeness strategy used is strongly influenced by their cultural background. The strategy used most often is the bald-on record strategy while the Off-record politenses strategy is the strategy that is the least used by the two main characters of the film. This suggests that an understanding of politeness strategies is needed to realize face-threatening actions (FTA). In other words, politeness strategies are used to maintain continuity and success in communicating.

Published: March 2021

For university students, a skill in writing a good summary of articles, books and other sources is very important. Rhetorical Précis, a summarizing template that consists of four dense and direct sentences, can be used to compose a precise summary. This research aims at exploring EFL students’ perceptions of the use of Rhetorical Précis. Using a survey study, a five-degree questionnaire was spread out to 47 students who had attended the Critical Reading course at a reputable university in Surabaya, Indonesia. The data from the questionnaire were analyzed quantitatively. In addition, a semi-structured interview was held with four of the students. The interview was recorded and transcribed to meet the need of this study. The findings of this study showed that most of the students had positive perceptions of each element of Rhetorical Précis. In short, the students perceived that the Rhetorical Précis summarizing template could be used  by the students to make a summary of the original texts precisely and accurately.
