This work studied the influence of MPEG-4 HE-AAC v.2 and MPEG-4 xHE-AAC compression algorithms on the reproduction performance of high-quality audio signals. The first part of the article is based on the analysis of earlier publications, studied quality of the compression algorithms for MPEG-4 ISO/IEC 14493-3 (AAC, AAC+SBR, PS, AAC+SBR+PS) and MPEG D Surround standards applied in MPEG-4 HE-AAC v.2 and MPEG-4 xHE-AAC codecs of DAB and DRM systems for digital audio broadcasting, respectively. It has been demonstrated that their use for processing of high-quality audio signals in the frequency range of 40…15000 Hz, allowed to reduce the digital-data rate at the output to 24…30 кbit/s, without observing noticeable phenomena. This conclusion was confirmed in the second part of the article, which described the results of relative comparison of the quality of reproduction of audio signals broadcasted via analogues FM or digital DRM channels. The equipment employed for their realization was described, as well as the methodology to obtain test recordings in order to perform the statistical data analysis. Further, the specific data scales were shown to evaluate the signal pairs being compared. Results of the experiments and their analysis confirmed that, for a digital data rate of 30 кbit/s obtained at the output of the MPEG-4 xHE-AAC coder, the difference in quality was rather weak for audio signals ranging from 40 to 15000 Hz, broadcasted via both analogues and digital channels. In addition, only a marginal difference was noticed for the signal pairs received from the digital output channels of the transmitter processor and DRM receiver. It has been demonstrated that the MPEG-4 xHE-AAC codec, compared to the previous MPEG-4 HE-AAC v.2 version, exhibited clear advantages for practical applications in terms of sound quality. Based on the gained experience, common criteria of deterioration of the data quality were formulated and generalized for all audio compression MPEG standards.
Consideration of phase distortions caused by the movement of geostationary repeaters when locating ground-based radio emission sources
Authors:   Saint Petersburg Electrotechnical University ", Gall Roman D. ,   LETI"
Published: October 2021

Currently, there are often cases of illegal use of the resource of relay satellites located in geostationary orbit, and the creation of unintentional and deliberate interference with legal users of satellite communication systems, for example due to non-compliance with the power standards of radio transmitting devices and antenna radiation patterns, as well as the rules for the frequency spectrum regulating. One of the possible stages of the response by the radio frequency service and satellite systems operators to such situations may be an operational assessment of locating of the interference ground radio emission sources that violate the established requirements. The existing methods for estimating the coordinates of radio emission sources operating through geostationary satellites-repeaters involve calculating the Cross-Ambiguity Function (CAF) of signals received from several satellites that relay the signals of the main and side lobes of the antenna pattern of the geolocated source. In the case of a low received signals SNR, it is required to record signals for a long time, and in such cases, to achieve a sufficient SNR at the correlator output, it is necessary to take into account not only the Doppler frequency shift between the signals, but also the change in the frequency shift caused by the change in the velocity vectors of the repeater satellites. The aim of this work is to study the recording duration, at which it is required to take into account phase distortions caused by a change in the speed of the repeater satellite and their effect on the SNR at the correlator output, as well as to develop a method for accounting for such distortions. The theory of digital signal processing and the method of simulation were used as research methods. As a result of the study, an assessment was made of the duration of the signal recording, at which the Doppler frequency shift can be considered constant; introduced the concept of a modified CAF, which takes into account the change in the Doppler frequency shift due to its approximation by a linear function; the maximum duration of signal recording was estimated, at which the proposed linear approximation is valid. It is concluded that in the case of using the modified CAF, the minimum duration of signal recording, at which the absence of correlator output SNR degradation will be guaranteed, is 8.1 times greater than when using the traditional CAF.

The article proposes criteria for multi-criteria selection of the configuration of the telecommunications network of a structural-dynamic continuous monitoring system. The mobility of the components of the monitoring system leads to periodic (or permanent) changes in the topology of the telecommunications network, through which data is transmitted in the monitoring system. Destabilizing effects of both natural and artificial origin also lead to forced changes in the topology of the telecommunications network. To select the configuration of the telecommunications network (a set of information sources, information consumers, data transmission network, and optimally formed information channels) both during the initial construction of the system and during the operation of the system of continuous monitoring for the detection of objects (on a given territory at a given time with a given probability), it is proposed to apply three criteria. The first criterion is the time of configuration formation, the second is the radius of resistance to destabilizing influences, and the third is an indicator of the continuity of information interaction between the elements of the system.
Modeling data transmission systems using modern information technologies
Authors:   Povolzhskiy state university of telecommunications  and informatics, Akhmetshina Eleonora G.
Published: October 2021

When modeling data transmission systems for various purposes, including computer and telecommunication networks, both components of mathematical modeling are widely used. These are simulation modeling and analytical modeling based on queuing theory. At the same time, researchers can always compare the results obtained by means of simulation and analytical modeling. From modern technologies of simulation modeling, one can single out the IT GURU Academic Edition technologies, represented by the Opnet Modeler and Riverbed Modeler software products with powerful graphical editors. Graphic editors allow you to create simulation models of data transmission systems of any complexity, and launch and run their models to obtain statistics of the main performance indicators of these systems. Comparison of the simulation results with the results of queuing systems (QS) of the G/G/1 type makes it possible to assess the adequacy of those and other mathematical models. This article summarizes the results of the author's publications on G/G/1 systems based on time-shifted distribution laws such as exponential, hyperexponential, and Erlang distribution. Thus, these distribution laws for the random variables used provide the coefficients of variation less than, equal or greater than one. This fact is important from the point of view of the queuing theory, because the average delay of claims in the system directly depends on the coefficients of variations in the time intervals for the arrival and servicing of claims.
On the question of choosing a method for analyzing transient processes for developing the theory of resolution time. Retrospective analytical review
Authors:   Kazan National Research Technical University  named after A.N. Tupolev-KAI, Lerner Ilya M.
Published: October 2021

One of the fundamental and central problems of radio engineering and communication theory was and remains the scientific problem of finding ways to potentially reduce the frequency band occupied by the signal, as well as reducing the power of transmitting devices, which provide the necessary speed and reliability of information transfer, that is, the problem of increasing the specific bandwidth. One of the key forms of solving this problem is the transition to the reception of information messages in conditions of strong intersymbol interference. Sufficiently encouraging results in this direction are shown by the theory of resolution time presented in the papers [1-5] for APSK-N- and PSK-n- signals. At the same time, as a mathematical apparatus in these works, it is used as a mathematical apparatus in the field of optimization and analysis of transient processes. At the same time, as shown in these papers, the correct choice of the mathematical apparatus for the analysis of transient processes is of paramount importance. At present, due to the constant growth of the volume of transmitted information, more and more attention is paid to the issues of the possibility of increasing the transmission speed due to the use of the transmission mode "above the Nyquist rate". According to the theory of resolution time, which has been developing quite rapidly recently, it is required to analyze the transient processes in linear selective systems (LSS). In this case, LSS makes it possible to implement frequency selective properties of real communication channels in the channel model. At the same time, the question of choosing a method for analyzing the transient process is quite acute, since it primarily determines the complexity of estimating capacity procedure. This paper presents a retrospective, analytical review of methods for analyzing transient processes in LSS and substantiates the need to apply the method of slowly varying amplitudes S.I. Evtyanov and its developing. On its basis, the simplest and most convenient method for analyzing transient processes was chosen as applied to phase radio engineering systems for transmitting information.

Published: October 2021

To amplify modern high crest factor telecommunication radio signals with high efficiency, switching operation modes of transistors and synthetic amplification methods are used. The most common of these are the Kahn method (EER – envelope elimination and restoration) and the outphasing method. However, application of these methods has a number of technological (in terms of element base capabilities) limitations on the bandwidth and dynamic range of amplified signal. To expand high-efficiency RF power amplifiers field of application, the possibilities of combination several different synthetic amplification techniques are being considered. Expressions are obtained for the theoretically achievable efficiency when combining the outphasing method with a bridge power combiner and pulse-step modulation of supply voltage. The dependence of average efficiency on the number of supply voltage levels is determined. RF amplified signal bandwidth and its dynamic range determine the minimum required pulse width of the PWM modulator for the EER amplifier. Variants of these characteristics dependence on the number of supply voltage levels are discussed with combined use of PWM and pulse-step modulation of the supply voltage. Directions for further research are formulated.
Analysis of the influence of Machine Learning algorithm parameters on the results of traffic classification in real time
Authors:   MTUCI, Krasnova Irina A.
Published: October 2021

The paper analyzes the impact of setting the parameters of Machine Learning algorithms on the results of traffic classification in realtime. The Random Forest and XGBoost algorithms are considered. A brief description of the work of both methods and methods for evaluating the results of classification is given. Experimental studies are conducted on a database obtained on a real network, separately for TCP and UDP flows. In order for the results of the study to be used in real time, a special feature matrix is created based on the first 15 packets of the flow. The main parameters of the Random Forest (RF) algorithm for configuration are the number of trees, the partition criterion used, the maximum number of features for constructing the partition function, the depth of the tree, and the minimum number of samples in the node and in the leaf. For XGBoost, the number of trees, the depth of the tree, the minimum number of samples in the leaf, for features, and the percentage of samples needed to build the tree are taken. Increasing the number of trees leads to an increase in accuracy to a certain value, but as shown in the article, it is important to make sure that the model is not overfitted. To combat overfitting, the remaining parameters of the trees are used. In the data set under study, by eliminating overfitting, it was possible to achieve an increase in classification accuracy for individual applications by 11-12% for Random Forest and by 12-19% for XGBoost. The results show that setting the parameters is a very important step in building a traffic classification model, because it helps to combat overfitting and significantly increases the accuracy of the algorithm's predictions. In addition, it was shown that if the parameters are properly configured, XGBoost, which is not very popular in traffic classification works, becomes a competitive algorithm and shows better results compared to the widespread Random Forest.

The solution of the two-dimensional wave diffraction problem for infinite cylinder of complex cross-section was considered by using the pattern equations method (PEM). A triangle and a Koch snowflake of first iteration were chosen as the geometry of the cross-sections of the cylinder. The numerical algorithms of the PEM for a single scatterer and for a group of bodies with the Dirichlet condition on their boundary are briefly presented, and the results of numerical calculations of the scattering characteristics for the above geometries are obtained using the PEM and the method of continued boundary conditions (MCBC). To check the convergence of the numerical algorithm in both methods, the optical theorem was used. The limits of applicability of the PEM for fractal scatterers are established. It is shown that for all convex bodies the algorithm of the PEM is sufficiently stable and allows obtaining calculation results with an accuracy acceptable in practice. In the case of a non-convex body, namely, a Koch snowflake, the algorithm of the PEM for a single scatterer turns out to be unstable and the acceptable accuracy can be obtained only if this geometry is considered as a group of bodies composed of convex geometries (for example, triangles).

The influence of errors on the distortion of signals transmitted and received in different spaces, in the general case, is a problem that has not yet been resolved. With the beginning of the spread of digital transmission systems, it became necessary to interface (match) various digital signals (streams) generated in accordance with the frequency of the master oscillators of individual transmission systems and terminal sources of discrete signals. At the same time, as a rule, these master oscillators operating at nominally the same frequency were not synchronized with each other. As a result, due to the real instability of the master oscillator frequencies, growing phase mismatches arose, which must be compensated. In the wellknown literature, particular cases of analysis and optimization of methods for displaying the original signal during its transformations during transmission from a source to a receiver have been investigated, and there is no general theory for studying this problem, the topic of this research is given in the article. The article examines the possibility of optimizing the choice of matching code combinations when comparing the elements of the original signal with its display when converting signals from one space to another. A method for determining the efficiency of signal conversion from one space to another is described.
Computer-aided optimisation of electronic circuit layout

Published: October 2021

The problem of optimal placement of elements of electrical and electronic circuits is considered. The minimum weighted length of the connections is selected as the criterion. The scheme is defined by a matrix of connections. We consider a fixed set of element positions and a distance matrix based on an orthogonal metric. This problem is a variant of the general mathematical model, called the quadratic assignment problem. The geometric limitation of the problem is that no more than one element is placed in one cell. Combinatorial analogs of the Gauss-Seidel method, the genetic algorithm, and the corresponding hybrid methods for solving the quadratic assignment problem with optimal placement of electronic equipment elements are developed and implemented on a computer. A series of computational experiments was conducted, which showed satisfactory computational qualities of the proposed methods. The proposed computational method, which is a combinatorial analog of the method of coordinate descent and one of the variants of the general approach based on paired permutations, is characterized by the best computational qualities among the methods studied in the article. According to well-known studies, the genetic algorithm is obviously no worse than the Monte Carlo method. The research conducted in the article shows that the method of penalty functions in the problem of placement and for the case of a genetic algorithm is ineffective. Therefore, it is of interest to consider permutations without repetitions as individuals of the population. This circumstance is taken into account at the stages of selection and mutation: at these stages, the standard calculations according to the genetic algorithm are supplemented by the procedure of paired rearrangements of genes in the chromosome. The article provides a detailed description of the program for the implementation of the genetic method on a computer.

Background: Physicians require breastfeeding education appropriate to their roles. The aim of this survey was to determine physician learning needs and to inform development of breastfeeding education for physicians.
Methods: A cross sectional survey was distributed to family physicians, pediatricians and obstetricians in a tertiary institution. Importance of knowledge to practice and confidence to manage was assessed for 18 learning topics proposed by a multi-specialty physician working group. Descriptive statistics, ANOVA and tests for equality of variances were calculated. Mean values of importance to practice and confidence to manage for each topic suggested learning priorities.
Results: The study group included 75 physicians. The most important topics were “informed choice when supporting newborn feeding,” “analgesics, antidepressants and other medications while breastfeeding” and “community resources for breastfeeding support.”  Confidence to manage was lowest for “latch assessment,” “what mom can do during pregnancy to promote milk production,” and “risk factors for delayed lactogenesis.” Preferred learning formats were 15-minute online modules and grand rounds.
Conclusions: Physicians acknowledged the importance of all topics but report lowest confidence to manage latch assessment, prenatal interventions to support lactogenesis and management of delayed lactogenesis.  Participants placed relatively low importance on learning about latch assessment despite the central nature of this skill in supporting early breastfeeding.

Published: October 2021

In March 2020, COVID-19 challenged health and educational systems across the country. The rapid reallocation of resources to ensure public safety had taken priority over educational obligations. Healthcare students were removed from clinical environments as their learning came to a grinding halt. While academic institutions were pivoting and transforming teaching and learning experiences, students responded to the pandemic with innovation, attending to gaps in patient care. As educators, we must understand how we can further support students and faculty to unleash innovative thinking during a crisis. To begin to address this educational need, academic institutions now have an opportunity to broaden the practice of education scholarship in accordance with best practices to nurture innovation and innovative thinking. What framework can aid us in this endeavor? In times of instability, Developmental Evaluation is an approach that can support the implementation of innovations within medical education. Using an example of an innovation in medical education, we offer six practical tips to begin to use Developmental Evaluation to support and enable learners and faculty in the creation of innovations and contribute to a broader definition of education scholarship.

This paper presents an analysis of the range of veterinary medicines registered in the territory of the Russian Federation and used for the prevention and treatment of helminthiasis. The Russian Federation is a leader in the development and production of anthelmintic medicines registered on its territory. Antiparasitic medicines used for the prevention and treatment of helminthiasis are divided according to the spectrum of action depending on the class of helminths. It was revealed that the majority of medicines (89 medicines – 58,17%) have a wide spectrum of action. Of these, 62 medicines (40,52% of the total amount of anthelmintic medicines) are intended for the treatment of nematodes and cestodoses. When distributing anthelmintic medicines among target animals, it was found that 75 medicines (49.02%) are intended for the treatment of productive animals, and 78 medicines (50,98%) are intended for the treatment of unproductive animals. When assessing the dynamics of state registration of anthelmintic medicines for veterinary use, it can be noted that over the past 4 years there has been a tendency towards an increase in the average annual registration.
Productive longevity of Holstein cows of the Leningrad population with different systems of housing

To identify the advantages of a tethering system (TS) or loose-housing system (LHS), a comparative analysis of the level of milk productivity and the duration of productive longevity of cows in the Leningrad Region was carried out for a livestock of 4,272 cows that left in 2015–2019. The following indicators were calculated: period of productive use (PPU) – age in days from the first calving to the retirement of the cow, lifetime milk yield (LTMY); milk yield (kg) for 1 milking day, for 1 day of PPU and 1 day of life (Efficiency of Milk Production – EMP) – calculated by dividing lifetime milk yield by the number of milk days, PPU or life. With TS the LTMY is higher by 10,634 kg, which is obtained for 107 additional days of their productive use, milk production for 1 day of milking, the day of use, EMP is higher by 8,2 kg, 6,7 kg and 4,6 kg, respectively, the majority of cows have an EMP level in the ranges of 10,01–15,00 kg of milk (32,0%) and 15,01–20,00 kg (38,2%), and 11,0% of animals have reached an EMP level of more than 20,00 kg of milk. With LHS mainly cows are concentrated in the ranges of 5,01–10,00 kg of milk (43,6%) and 10,01–15,00 kg of milk (46,6%). Desirable cows with LTMY over 30 thousand kg, and in this range, the EMP is almost 10 times higher with TS (43,9 instead of 4,5%). The results obtained cannot be attributed to the advantages of TS. This is confirmed by the great influence of the father on the EMP (factor «Sire» – 0,679) or the inherent genetic potential of productivity, and only by 0,268 system (factor «System of housing») and by 0,296 (factor «Farm») housing conditions on the farm. The «System of housing» influences more on milk yield per 1 day of PPU than on EMP and LTMY (0,342 instead of 0,268 and 0,110, respectively). The effectiveness of LHS is evidenced by the fact that when comparing animals with the same level of EMP under this system, they are used for a longer time and, accordingly, produce more milk per life. So, with a level of 5,01–10,00 kg of milk, cows have a LTMY of 18,1% more with LHS, which were used for 0,54 lactation with PPU for 211 days longer than analogs with TS. A similar trend is observed at the level of 10,01–15,00 kg (+20,8%, +1,17 lact., +461 days) and at the level of 15,01–20,00 kg (+11,3%, +1,18 lact., +499 days). Therefore, for profitable dairy production with a LTMY of more than 30 thousand kg of milk during the PPU of Holstein cows with a LHS, attention should be paid to the level of the inherent genetic potential of productivity (according to the analyzed sample, at least 8000 kg of milk), that is, to select bulls with high breeding qualities.

This article discusses the topic of confirming the conformity of the quality of feed and feed additives coming into circulation at the Russian feed market. The idea is substantiated that technical regulation measures applied without fail to feed and feed additives are not sufficient to reduce the risk of a low-quality product entering circulation. It was found that the presence of registration of a feed additive is not a criterion for issuing a declaration of conformity and, accordingly, it is possible to draw up a declaration for an additive without its state registration. The article aims to draw the attention of manufacturers of feed and lump additives and their consumers to the issues of product quality and possible ways to solve this problem. Also, the manufacturer has the opportunity to confirm the conformity of the quality of the product on a voluntary basis. Based on the statistical analysis carried out, as well as the use of information on the number of registered and valid declarations for feed, feed additives registered in other EAEU member states, an analysis of data on the number of valid declarations registered in the Russian Federation in the Rosaccreditation register was formed.

The article examines the effect of fat obtained from the dried larva of Hermetia illucens on the metabolic processes and rumen digestion in Romanov sheep. The obtained research results showed that fat feeding did not affect the level of total blood protein (81,03 vs. 82,27 g/l; p>0,05) with almost the same ratio of albumin to globulins (0,75 vs. 0,82; p>0,05). The level of urea in the animals of the experimental group was also at the control level (6,16 vs. 6,93 mmol/l; p>0,05). A higher level of AST in the blood serum of the experimental animals by 25,5% (p<0,05), with a General orientation to the increase of the ratio of AST/ALT (p>0,05). Fat feeding resulted in an increase in the level of total bilirubin in to 78,3% (p<0,01), and 25,5% (p<0,05) in AST levels compared to the control, which may indirectly indicate an intensification of metabolic processes in animals of this group, with almost the same level of alkaline phosphatase. In the sheep of the experimental group, there was a slight increase in the fermentation processes in the rumen, as evidenced by an increase in the level of VFA by 6,9% with a decrease in pH by 0,13 units, with an increase in the concentration of ammonia by 24,5% by 3 hours after feeding compared with the indicators of the control group.

Work ethic is said to be a determining factor for the success of individuals, groups, institutions and also the widest part of the nation in achieving its goals. The implementation of public administration is also influenced by the work ethic possessed by public officials in carrying out the needs of society. Work ethic is the main thing in carrying out work to achieve excellence in character and excellence of character that results in superior work and performance. Of course, these advantages come from the fruit of a human's perseverance. The ability to live work is very important in an effort to create excellence. The point is that when we do a job, we are essentially doing a service process. Living up to work as a service requires transcendent abilities that go beyond the small human space. This can all be seen and contained in the work ethic at the Indo Global Mandiri School of Sharia Economics and Business, Palembang.

Hand Sanitizers generally contain chemicals in the form of alcohol and triclosan. However, the use of these two ingredients can cause danger if they are used continuously, therefore the Hand Sanitizer antiseptic product was innovated using ethanol extract of cucumber fruit which contains antibacterial compounds to reduce the use of both ingredients. The purpose of this study was to make a Hand Sanitizer gel formulation from ethanol extract of cucumber fruit and to determine the physical stability of the preparation during storage. Hand Sanitizer Gel of cucumber fruit ethanol extract is made in three formulations withdifferent extract concentrations, namely F1 (1.5%), F2 (2.5%), and F3 (3.5%). The results of the organoleptic test included the three formulations, namely that the three of them did not change during storage. The results of the homogeneity test included F1 and F2 which were stated to be homogeneous while F3 was not homogeneous. The results of the pH test included that during storage the three had decreased until week 3 and increased thepH again at week 4. The results of the spreadabilitytest of the three preparations met the requirements for the gel preparation, but in the adhesion test the three preparations did not meet the adhesion requirements of the gel preparation.

Diabetes Mellitus (DM) is a chronic condition because of the body cannot produce insulin normally or insulin cannot work effectively. This damage if chronic occurs will cause complications. In the province of East Java the prevalence of DM sufferers of 2.1% ranks 9th, and prevalence of DM in Sidoarjo is patients with a diagnosis of 3.6% of the total population of East Java. The purpose of this study was to look at the profile of oral antidiabetic therapy in type II diabetes mellitus patients in the outpatient installation of Anwar Medika Hospital. The sampling method used is non random sampling Data retrieval from 17 February to 30 April 2020 with a data collection sheet that has been validated. Management of DM patients consists of 4pillars that is education, nutritional therapy, physical activity and pharmacology. The study was conducted in an outpatient installation of Anwar Medika Hospital with 62 samples that fit the inclusion criteria. The results showed that most patients with type II diabetes mellitus were female, as many as 44 patients (70.96%) of 62 patients. Patients with type II diabetes mellitus who most went to Anwar Medika Hospital and got ADO prescription drugs were patients with an age range of 56-65 years as many as 24 patients (38.70%) of 62 patients. Most of the most commonly prescribed ADO drugs by doctors were Glimepirid 34 (91,89%) and combination of 2 kinds of drugs by 22 patients (88%) out of 62 patients. Most patients use more than 1 drug. It is therefore recommended that pharmacy installation officers at Anwar Medika Hospital can provide an understanding of DM, provide counseling related to medicines prescribed to patients and monitor the success of patient therapy. This research is worthy of ethics with numberNo.633/RSAM/VII/2020

Objectives. The main objective of the present study is to assess the sensitivity and specificity of a retrospective diagnostic of lymphatic tuberculosis (LTB), testing frozen samples using gene amplification PCR methods. The secondary objective was to compare the results of two different commercial tuberculosis gene amplification methods for this purpose. Material and methods. We retrospectively studied 38 frozen samples, previously processed for mycobacterial culture between January 2014 and August 2019. The results of the previous cultures were: 21 samples positive for Mycobacterium tuberculosis complex (MTB) (5 being smear positive), 7 samples culture positive for Mycobacterium avium-intracellulare complex and 10 samples which were mycobacterial culture negative and discarded for LTB diagnosis, used as controls. The samples were processed using two gene amplification methods: Xpert® MTB/RIF Ultra (Cepheid) and Abbott RealTime MTB Assay (Abbott). Results. Compared to initial culture results the sensitivity and specificity of Xpert® MTB/RIF Ultra were 57.1% and 100% and 52.3 % and 92.5%, respectively for the Abbott RealTime MTB assay. The differences were not statiscally significant. In addition, there were no differences according to the period of freezing. Conclusions. Gene amplification of frozen samples confirmed the diagnosis of lymphatic TB in almost 60% of cases, allowing retrospective diagnosis in initially non suspected cases. Both gene amplification techniques tested were equally useful.
Transitioning from Interdisciplinarity to Transdisciplinarity in Applied Translation Studies: Towards Transdisciplinary Action Research in Translators’ Workplaces
Authors: MASSEY GARY
Published: October 2021

Abstract Since the beginnings of translation studies, applied translation research has set out to address the practices, processes and products of translation in both work and education. The contexts in which these are realized are embedded in broader sociotechnical systems
as well as in the specific settings where translation is performed. Although the situated nature of professional translation is uncontroversial and suggests that it should be investigated in situ, workplace-based, organization-oriented research in applied translation studies is a relatively
recent and still under-developed phenomenon. The nascent interest in it is partly due to advances in research tools and practices, but mostly to an emerging but still largely implicit transdisciplinary research framework. This article argues that the actual and potential impact of transdisciplinarity
should frame translation research more explicitly. It considers how the growing diversification of professional translation and its convergence with other communication professions calls for applied translation studies to adjust to new realities. It explores current developments in professional
translation practice, presents a use case of workplace-based research, and concludes with a model of transdisciplinary action research that can serve as a structured framework for investigating and learning from rapidly evolving professional processes and practices in translators’ sociotechnical
workplaces.
