Pharmacoeconomic analysis of the use of a fixed combination of tiotropium bromide and olodaterol as maintenance therapy in patients with chronic obstructive pulmonary disease in the Russian Federation
Authors: Zyryanov S. К. , Dyakov I. N.
Published: July 2022

Objective: to evaluate the pharmacoeconomic effectiveness of the use of a fixed double combination of tiotropium bromide + olodаterol in order to treat chronic obstructive pulmonary disease (COPD) in comparison with less expensive monotherapy with long-acting beta-2-agonists (LABA) or long-acting anticholinergics (LAAC) with its insufficient effectiveness.

Material and methods. The analysis of the impact on the health care system budget of the use of a fixed double chemical combination was carried out. The combination used was the one of tiotropium bromide + olodаterol in patients suffering from COPD who do not achieve effective disease control during LABA or LAAC monotherapy. We used published data on the distribution of patients into groups according to the classification of the Global Initiative for Chronic Obstructive Lung Disease (GOLD), also according to the therapy used and the frequency of exacerbations with hospitalization, obtained in a Russian epidemiological study. Direct and indirect costs associated with basic therapy and treatment of exacerbations requiring hospitalization were estimated as well.

Results. Previously, it was shown that about 21.8% of patients with GOLD D severity of COPD receive therapy of insufficient efficacy (LABA monotherapy or long-acting M-cholinolytics). The use of a fixed combination of tiotropium bromide + olodaterol in such patients instead of monotherapy will reduce the direct costs of hospitalization by 21.1%, and the total costs (direct and indirect) – by 4.6%. On the scale of the Russian Federation, this will save 17.2 billion rubles a year.

Conclusion. The results obtained showed that, despite the reasonably high cost of a fixed double combination in comparison with monopreparations, the use of double bronchodilating therapy allows to achieve more effective treatment and reduces both direct medical costs associated with hospitalization of patients with exacerbations of COPD, and direct non-medical and indirect costs associated with absenteeism of patients to work due to temporary disability as a result of hospitalization.
The Image of Personal Future in High School and College Students
Authors: Andreeva A.D.
Published: July 2022

The article is devoted to the analysis of empirical data on the structure and content of the image of personal future among high school and junior college students. The study was carried out using the method of prototypical analysis of free associations by P. Verges, developed in line with the concept of social representations by S. Moscovici. The hypothesis was tested that the respondents' image of the future will be different depending on their gender and level of education. The study involved junior college students (153 people) and students of grades 10-11 of secondary schools in Moscow, Chelyabinsk and Orsk (191 people). It is established that the aspiration to the future still remains the leading psychological characteristic of adolescence, and the expressed optimism of the personal future image is interpreted as a predictor of readiness to overcome the crisis of self-determination. Gender differences in the structure and content of the personal future image are manifested in the orientation of young men mainly to professional self-realization, while for young women family and the emotional comfort associated with it are more important. The educational status of respondents also influences the content of the psychological image of personal future. Schoolchildren are distinguished by pronounced immaturity, naivety and cliched social ideas about their adult life, while college students show a somewhat more realistic picture.

Authors: Merzlyakova D.R.
Published: July 2022

The article presents the results of an empirical study of the characteristics of psychological health and professional burnout of subject teachers of educational organizations with different qualification categories. The specific of the occurrence of professional “burnout” in the context of digital transformation of the educational process is considered. The study involved respondents aged 24 to 63 years, of which 74% were female – 232 people (N=232), of which 110 people of high professional skill (N=110) and 122 teachers of low professional skill (N=110). To achieve this goal and test the hypothesis, empirical methods were used: the questionnaire “Assessment of job satisfaction” by V.A. Rozanova; the MBI professional burnout questionnaire by K. Maslach and S. Jackson, adapted by N.Ye. Vodopyanova; methodology for diagnosing psychological health by A.V. Kozlov, which includes the following scales: “Strategic vector”, “I-vector”, “Intellectual vector”, “Humanistic vector”, “Creative vector”, “Family vector”, “Prosocial vector”, “Spiritual vector”. It was revealed that subject teachers of high professional skill are more susceptible to the syndrome of professional “burnout”, which manifests itself in the form of cynical attitudes towards the subject of their work and decrease in professional motivation. At the same time, they are more intellectually developed, inclined to creativity and humanism in comparison with teachers of low professional

Authors: Sezer Berkant , Kargul Betul
Published: July 2022

Objective: The objective of this study was to evaluate the remineralization effect of two different mineral containing agents on white/creamy and yellow/brown demarcated opacities in incisors in children with molar-incisor hypomineralization (MIH) by using laser fluoresence (LF). Study Design: Fifty-three children (n=401 lesions) with MIH were randomly divided into three groups: (1)calcium glycerophosphate (CaGP), (2)casein phosphopeptide amorphous calcium fluoride phosphate (CPP-ACFP) and, (3)control (1450 ppm fluoride toothpaste). Remineralization was evaluated by means of LF, at baseline, after one and threemonths. Anova Test for Repeated Measurements in intra-group comparisons in evaluating the effectiveness of remineralization agents. One-way Variance Analysis (ANOVA) and Tukey-Kramer Multiple Comparison test were used in the comparisons between groups and, Student Newman Keuls Multpile Comparison Test was used to determine the differences between the measurement averages in case of p<0.05. Results: There was a significant improvement in MIH-lesions over time in all groups (p<0.001), with no differences between groups. The highest percentage of change was observed in CPP-ACFP in lesions LF≤20 scores and the mean percentage of change LF>20 scores, the highest percentage changes in CaGP. There was no significant difference between the groups over the time for all the used outcome measures (p>0.05). Conclusion: The additional use of both mineral containing agents in MIH-affected teeth improved these hypomineralized lesions with mineral deposition. Even if both agents could be used in the hypomineralized teeth with demarcated opacities, future studies are recommended the long-term effect of these mineral containing agents with longer observation and a larger sample size.

Published: July 2022

Objective: To assess decision making process and knowledge level of dentists treating children with type 1 diabetes. Study design: Cross-sectional survey among dentistry residents and dental specialists working in clinics that provide dental care to children with type 1 diabetes. Results: A total of 166 respondents were included. 42% of respondents perceived that they have sufficient knowledge to treat children with diabetes, in correlation with an average score of 1.9 out of 4 on knowledge questions. Over 80% of dentists decided to treat patients by consulting with the treating physician or by checking HbA1c and glucose blood levels independently. Greater knowledge was associated with a significantly higher tendency of the dentists to determine if the child’s diabetes is controlled, and to refer less often to the hospital. Furthermore, greater knowledge was also associated with dentists’ greater perception that they have enough knowledge, skills and confidence to treat children with diabetes. Conclusions: The study revealed significant gaps in the knowledge on diabetes among dentists who provide dental care to children. Dentists, pediatricians, endocrinologists, and other healthcare professionals who provide care for children should be encouraged to collaborate to create a mutual knowledgeable work environment for delivering best care to their patients.

Published: July 2022

BACKGROUND: Theme of this article is actual because issues of the reliable and cost-effective opera-tion of augmented automotive piston engines are still not solved. An important aspect of solving the problem is rational oil supply of the cylinder-piston group.
AIMS: The purpose of this work is the required minimum motor oil level estimation for the hydrodynamic lubrication of the cylinder-piston skirt pair. There were set and solved the tasks of determining the volume of motor oil capable of filling: 1) cavities of the flat-topped surface of the cylinder; 2) a raised surface of the piston skirt and 3) the piston skirt clearance. The object of study is an automotive diesel.
METHODS: Three types of analytical determination of the total volume of the cavities of the rough surface and the piston skirt clearance were used as methods for estimation of a motor oil level.
RESULTS: It was found, that the estimation with the well known formula for oil volume (a method 1) gives the overevaluated result of oil level estimation, in comparison with methods 2 and 3, which taking into account the real geometry of cavities and roughness parameters. The advantage of method 3 was determened by criteria of generalization and of simplicity to apply. Using the method 3, the estimated volume of motor oil ensured the hydrodynamic lubrication mode of the cylinder piston skirt pair of the object of study was obtained.
CONCLUSION: The analytical expressions obtained by method 3 can be recommended to optimize the piston engine lubrication systems for reducing the friction and wear losses as well as to minimize a risk of oil starvation and increased oil consumption through burning.

Published: July 2022

SUBJECT OF THE STUDY: Is the process of preliminary separation of loose grains from combed grain heap on the slatted bottom of the feed elevator of a combine harvester.
AIMS: Is an efficiency evaluation of the combed grain heap separation on the slatted bottom of the inclined chamber of a combine harvester in the field and to compare the degree of crushing of free grain depending on its supply to the threshing device or directly to the cleaning system.
METHODS: All studies were carried out on winter wheat of the Moskovskaya 56 variety with a yield of 30 c/ha. Plant height varied within 0,60,9 m with a grain ripeness of at least 98% and a moisture content of 14%. The serial grain header ZHO-5 OZON manufactured by PJSC Penzmash was aggregated by the Niva-Effect combine harvester with a constant speed of 8 km/h and a stripping cylinder speed of 485 min-1. The field experiments were divided into two stages. The first series of experiments was devoted to evaluating the efficiency of preliminary separation of combed grain heap on the slatted bottom of the experimental feed elevator. During the second series of the experiment, grain was harvested with a serial feed elevator without its preliminary separation.
RESULTS: According to the results of the first series of studies, it was found that the passage of loose grain through the holes of the slatted bottom of the inclined chamber is 91,6%. At the same time, grain crushing in the feed elevator did not exceed 0,5%, and in the bunker 1,75%. During the operation of the combine with a serial feed elevator without preliminary separation of the combed grain heap, the crushing of the bun-ker grain was within 5,25%.
CONCLUSION: The practical implementation of such a technical solution makes it possible to 3 times the grain crushing in a bunker by the working bodies of the threshing machine.
About the possibility of using natural gas as a fuel on agricultural tractors
Authors: Kulchitskiy Alexey R.
Published: July 2022

AIMS: Evaluation of the effectiveness of converting diesel engines used in agricultural self-propelled vehicles to fully or partially natural gas (methane) fueled engines.
METHOD: Is analytical.
RESULTS: In agriculture up to 25% of operating expenses are fuel costs. However, the only number of the concomitant objective and subjective factors allow us to estimate expedience and efficiency of converting diesel engines used in agricultural self-propelled vehicles for full or partial supply of natural gas (methane). On the one hand, the price of an equivalent amount (in terms of work performance) of natural gas is more than 2 times lower than the price of diesel fuel. At the same time, natural gas is the most environmentally friendly hydrocar-bon fuel. But, on the other hand, the underdeveloped refueling infrastructure is obvious, and the environmental friendliness of natural gas itself is not a guarantee of the environmental friendliness of the engine itself. Also, the safety of gas equipment operation under high pressure is an important matter.
CONCLUSIONS: Firstly, the use of natural gas instead of diesel fuel requires taking into account the difference in the physicochemical characteristics of these fuels, which determines both the requirements for the organization of the working process and the advantages and disadvantages of such replacement. Secondly, the combustion process of natural gas, compared to diesel fuel, is characterized by in-creased formation of water leading to more intensive watering of lubricating oil, although it re-duces carbon dioxide emission into the atmosphere. Safety of natural gas equipment operation plays an important role, and first of all, it is concern of cylinders that are filled at pressure of 20.025.0 MPa.

The prevalence of candidate gene polymorphic alleles associated with personality disorders was studied in a sample of healthy male Military Innovation Technopolis ERA recruits, science mouth operators of Caucasian race aged 2327 (median age 24). Genotyping of 10 studied polymorphic variants of genes was carried out using polymerase chain reaction in real time. According to the results, the distribution of genotypes in the studied group of single nucleotide polymorphisms corresponded to HardyWeinberg equilibrium, except for the C677T MTHFR variant (rs1801133). The occurrence of minor alleles was as follows: 0.500 for A1438G and 0.310 for C102T (HTRA2); 0.175 for G-6A (CNTF); 0.508 for C T (UCP2); 0.270 for A1298C and 0.325C677T (MTHFR); 0.278A2756G (MTR); 0.571A66G (MTRR); 0.381Alu Ins/Del (ACE); 0.294G1444A (PPARGC1A). In the studied sample, the frequency of occurrence of minor alleles of 10 genetic markers correlated with data collected on people of European descent. The greatest statistical deviation was observed by comparison with data on people of African descent. Statistically significant concordances with different populations and studies conducted in them are the basis for including the selected polymorphisms in a candidate list of psycho-emotional and neurological pathologies influencing the occupational fitness of servicepersons. However, reliable data on the association between mental disorders and the development of degenerative disorders are not available simultaneously in all populations; therefore, additional research is required on this subject.

Risk factors for the development of type 2 diabetes mellitus were assessed in 212 military personnel aged 2045 years serving under a contract, of which 95 people (an experienced group with risk factors) and 117 people without risk factors (an experienced group), as well as 60 practically healthy males who are not military personnel Ministry of Defense of the Russian Federation aged between 18 and 45 years (control group). It was revealed that the indicators with the greatest influence on the development of type 2 diabetes include older age, body mass index, waist circumference, insulin resistance index, and the results of the psychological questionnaire Tendency to deviant behavior on the scale of Aggressiveness as well as the questionnaire Strong-willed self-control. It was found, on 3-year follow-up, that prediabetes developed in 8 (8.4%) patients of the experimental group with risk factors for type 2 diabetes mellitus who did not have carbohydrate metabolism disorders, and in 8 (6.8%) patients of the experimental group. At the same time, type 2 diabetes mellitus occurred in 2 (2.5%) patients of the experimental group and in 2 (1.7%) military personnel of the experimental group with risk factors for type 2 diabetes but initially normal glycemic indices, as well as in 8 (8.4%) patients of the same group who had prediabetes at the beginning of the study. In addition, prediabetes was detected in 2 people of the control group after 3 years and type 2 diabetes mellitus in 1 person. According to the results of the study, a mathematical model is proposed to assess the likelihood of developing type 2 diabetes in military personnel with a waist circumference 94 cm. The proposed model has a sensitivity of 95% and a specificity of 91%. The prognostic value of a negative result is 89.2%, and that of a positive result is 87%. Thus, military personnel with a waist circumference of 94 cm are characterized by a more frequent development of new cases of prediabetes and type 2 diabetes mellitus than civilians, which is due to the stressful nature of military service. The use of the proposed mathematical model will make it possible to predict the development of carbohydrate metabolism disorders in military personnel with a waist circumference of 94 cm over a 3-year period with the identification of a risk group requiring the use of a set of preventive measures aimed at reducing body weight.

Published: July 2022

The paper presents professionally important qualities of the cadets of the Krasnodar Higher Military Aviation School of Pilots named after the Hero of the Soviet Union A.K. Serov, necessary for mastering the flying profession, and highlights the influence of the professional self on the degree of their success in flight training. The dynamics of changes in the professional self as a component of the professional self-concept among cadets with different levels of success in flight training have been experimentally investigated. The paper also presents the results of the psychological examination of cadets regarding the stable dominant mental state, characteristics of the psychological and sociopsychological levels of the dominant mental state according to the method of L.V. Kulikov (short version) and their relationship with the level of formation of flight skills. Cadets with a high level of success in flight training were characterized by more pronounced increases in average values on the scales activepassive attitude to the life situation, tone: highlow, stabilityinstability of the emotional background and satisfactiondissatisfaction with life in general, which indicated the formation of more professional self. However, too much increase in the level of the self-concept can lead to negative results. Inadequate self-concept negatively affects the functional state of cadets. In this regard, a personalized approach to the medical support of cadets flights and their dynamic observation, taking into account individual psychophysiological characteristics, is relevant. The participation of an aviation doctor in the training of cadets of aviation schools with a pronounced professional self helps the instructor pilot in organizing a personalized approach; the formation and development of professionally important qualities, fostering a well-founded sense of confidence in their abilities, strengths, and capabilities from the very beginning of flight practice; motivation of cadets to strive to improve their flight skills; and assistance in their awareness that the successful completion of the task and flight safety depend on a real assessment of their professional skills and level of flight training.

The recent vaccination campaign targeting the new coronavirus infection (COVID-19) carried out in the Armed Forces of the Russian Federation, on the background of the current unstable global pandemic situation, makes it necessary to study post-vaccination population immunity to the SARS-CoV-2 virus and thus identify key features of immunity in organized military collectives. In the future, this will make it possible to objectively assess the risks of a worsening pandemic situation, effectively adjust the ongoing sanitary and anti-epidemic measures aimed at preserving and strengthening the health of military personnel, as one of the main conditions for maintaining the combat readiness of the Armed Forces of the Russian Federation. During a study conducted on epidemic indications, it was found that vaccination with Gam-Covid-Vac contributes to the formation of collective immunity with 95% effectiveness. A gender-based analysis of the immune response showed that the proportion of persons who lack class G immunoglobulins to SARS-CoV-2 among females is twice than that among men (9.3% and 4.7%, respectively). Seroprevalence indicators, classified by blood group, range from 94.4% (AB (IV) Rh) to 97.4% (A (II) Rh). There were no significant differences in seroprevalence between groups of people with different blood groups; however, the highest value of seroprevalence was seen among military personnel with blood group A (II) Rh. In this context, it is advisable to continue monitoring the formation of immunity in individuals with various blood groups. The results obtained made it possible to form a primary medical and social portrait of a serviceman with the most adequate immune response to the introduction of the Gam-Covid-Vac vaccine (a man under the age of 20 with blood type A (II) Rh) and to draw a conclusion about the high effectiveness of vaccination in military units (formations) staffed by conscripts and military educational organizations.
Predictive Model and Probabilistic Assessment of Sliding Displacement for Regional Scale Seismic Landslide Hazard Estimation in Iran
Authors: Jafarian Yaser , Lashgari Ali , Haddad Abdolhosein
Published: July 2022

A semiempirical model is presented to predict earthquake-induced sliding displacement of earth slopes based on earthquake records of the Iran plateau. The earthquake database selected for the analyses contains 3319 records (of two horizontal components) of ground acceleration relative to 738 earthquakes that occurred in Iran. The predictive model is a function of Arias intensity, yield acceleration coefficient, and the slip length of sliding mass. The performance of the proposed model was tested by comparing its predictions with those of other regional and global models. As an example of possible application of the proposed model, fragility curves are presented, which were calculated according to three damage levels.

Published: July 2022

Picking arrival times of P and S phases is a fundamental and time-consuming task for the routine processing of seismic data acquired by permanent and temporary networks. A large number of automatic pickers have been developed, but to perform well they often require the tuning of multiple parameters to adapt them to each dataset. Despite the great advance in techniques, some problems remain, such as the difficulty to accurately pick S waves and earthquake recordings with a low signal-to-noise ratio. Recently, phase pickers based on deep learning (DL) have shown great potential for event identification and arrival-time picking. However, the general adoption of these methods for the routine processing of monitoring networks has been held back by factors such as the availability of well-documented software, computational resources, and a gap in knowledge of these methods. In this study, we evaluate recent available DL pickers for earthquake data, comparing the performance of several neural network architectures. We test the selected pickers using three datasets with different characteristics. We found that the analyzed DL pickers (generalized phase detection, PhaseNet, and EQTransformer) perform well in the three tested cases. They are very efficient at ignoring large-amplitude transient noise and at picking S waves, a task that is often difficult even for experienced analysts. Nevertheless, the performance of the analyzed DL pickers varies widely in terms of sensitivity and false discovery rate, with some pickers missing a significant percentage of true picks and others producing a large number of false positives. There are also variations in run time between DL pickers, with some of them requiring significant resources to process large datasets. In spite of these drawbacks, we show that DL pickers can be used efficiently to process large seismic datasets and obtain results comparable or better than current standard procedures.

From June to August 2021, we deployed a dense seismic nodal network across the Hengill geothermal area in southwest Iceland to image and characterize faults and high-temperature zones at high resolution. The nodal network comprised 498 geophone nodes spread across the northern Nesjavellir and southern Hverahlíð geothermal fields and was complemented by an existing permanent and temporary backbone seismic network of a total of 44 short-period and broadband stations. In addition, we recorded distributed acoustic sensing data along two fiber optic telecommunication cables near the Nesjavellir geothermal power plant with commercial interrogators. During the time of deployment, a vibroseis survey took place around the Nesjavellir power plant. Here, we describe the network and the recorded datasets. Furthermore, we show some initial results that indicate a high data quality and highlight the potential of the seismic records for various follow up studies, such as high-resolution event location to delineate faults and body- and surface-wave tomographies to image the subsurface velocity structure in great detail.
Progressive failure modeling of composite materials leveraging multiscale non-destructive evaluation data
Authors:   , Bahadori Mohammadreza , Kontsos Antonios
Published: July 2022

The reliable use of fiber reinforced composites (FRCs) in engineering applications depends, among other factors, on the quality of predictions related to their evolving damage state, which further affect design, operation and maintenance conditions. In this context, although a wealth of mechanical behavior, characterization, and failure data and information are available, it is still challenging to understand and predict the failure process in such materials. The main reasons for this deficiency are two. First, the failure processes in FRCs are fairly complex and highly variable given the available manufacturing, processing and usage parameters, which result in unique challenges when monitoring and simulating their performance. Second, despite the several modeling approaches developed using e.g. the Finite Element Analysis (FEA) method, it remains challenging to extend the use of such models across time and lengths scales. This dissertation targets the development of a data-driven modeling approach that is based on a key difference with respect to the previously reported methods on composite damage modeling. Specifically, instead of merely using a number of inputs for material and failure properties based on literature or some experiments, the presented approach targets to create computational workflows that enable the use of nondestructive evaluation data, collected at several scales to generate progressive failure inputs to FEA models, which are first calibrated for their predictions at the material scale and then use similar data to tune aspects of damage initiation and evolution at the structural scale. To demonstrate this approach, a particular class of FRCs is used and a number of analytical and numerical tools are developed or adapted to achieve this type of data-driven FEA modeling. The overall research output, demonstrates that such computational workflows are now possible to provide insights into progressive failure analysis of composite materials, which could impact all phases of design, manufacturing and use of them in applications.
An Exploratory Case Study of a District Initiated Antiracist Professional Development
Authors:   , Baig Fatima , Provinzano Kathleen T
Published: July 2022

In preparing educators to lead equitable and antiracist school communities, professional development programs must encompass historically accurate and representative doctrine of all learners. To prepare educators to inform all students about systems of inequity within the United States requires excellence in antiracist knowledge and practices. As key stakeholders, educators have the ability and skillset to address said challenges in their classrooms and professional learning environment. This exploratory qualitative case study explored how one voluntary district-initiated antiracist professional development series, titled I. N. P. aligned with the tenets of Critical Race Theory, and how educators enacted key elements of the professional development in their respective roles to resolve Azadi Public Schools' goal for creating an antiracist school district. Through an in-depth artifact analysis of the planning and implementation materials, semi-structured interviews, and reflective journal responses, the study was found to be rooted within the tenets of Critical Race Theory, culturally relevant, and multicultural pedagogy. Low participation in the study identified unintended outcomes of educator exhaustion due to the Covid-19 pandemic and race-based trauma. The political context of Critical Race Theory posits this study with implications for policy and practice grounded within counter storytelling and the amplification of the voices and lived experiences of people of color in support of learning and healing.
Hardware-Software Co-design for Neuromorphic Computing
Authors:   , Balaji Adarsha , Das Anup
Published: July 2022

Neuromorphic devices represent an attempt to mimic the computational dynamics and distributed architecture of mammalian brains. Mixed-signal neuromorphic platforms executing Spiking Neural Networks (SNNs) show significant gains in computational speed and energy consumption, when compared to recent deep learning accelerators. However, with growing model size and complexity of SNN-based applications and learning algorithms, allocating resources efficiently on neuromorphic hardware, while ensuring optimal performance, in terms of algorithm accuracy, latency and energy consumption, is becoming increasingly challenging. Therefore, there is a growing need for an extensible simulation framework that can (1) perform architectural explorations with SNNs, including both platform-based design of today's hardware, and (2) hardware-software co-design and design-technology co-optimization of the future. In this thesis, a hardware-software co-design framework is presented with an aim to (1) design large scale SNNs (2) compile SNN-based applications for neuromorphic hardware, (3) optimize the allocation of resources on the neuromorphic platform to execute the compiled SNN-based application, and (4) design a novel communication architecture (CA) for future neuromorphic platforms, with an aim to address and ensure the scalability of crossbar-based platforms. The proposed framework will significantly improve the performance of existing neuromorphic platforms, in terms of algorithm accuracy, latency, energy consumption and reliability, and explore architectural improvements to address the limitations of existing platforms.

This mixed-methods study was focused on investigating how the demands of the teachers' workday alters their creative behaviors and how school leaders influence and shape creativity in the workplace. The k-8 school selected for this study was chosen because it has encountered difficulties increasing and maintaining student achievement. Via insights acquired from current and former teachers, the researcher is inclined to assume that academic gains may be achieved if creativity were more of an integral, cohesive part of the teaching staff's ideology and daily routine. The design and rationale of this study explored the psychological and environmental factors that affected teachers' acceptance of change to understand what steps can be taken to improve the school's culture of creativity and innovation. The conceptual model developed to inform this study employed a psychometric test - the Reisman Diagnostic Creativity Assessment (RDCA). Kotter's 8-Step Process for Leading Change was also used to explore how various elements of the organization affect employee commitment. 35 teachers chose to participate in the RDCA portion of the study. 12 teachers volunteered to be telephone interviewed by the researcher. This study uncovered four concerns that may explain why creativity is not thriving at the school: 1) teachers have a below average tolerance of ambiguity that may affect their creative attitude and behavior; 2) teachers demonstrate an elevated proclivity to be extrinsically motivated that may discourage them from trying new instructional methods, ideas, or products; 3) time constraints place an overwhelming burden upon the teachers' opportunities to be creative; and 4) teachers are not encouraged to take risks which reduces the likelihood that they will discover and implement creative ways of engaging students in the learning process.
The Never-ending Story: Postmedia, the Competition Bureau, and Press Ownership in Canada
Authors: Edge Marc
Published: July 2022

The 2014 purchase by Canada’s largest newspaper chain of its second-largest chain increased concentration of newspaper ownership considerably. The deal’s 2015 approval by the Competition Bureau, some scholars noted, provoked little outcry over the latest federal regulatory failure to stop the increased concentration level. A series of inquiries, from the 1981 report of the Royal Commission on Newspapers to Senate reports in 1970 and 2006, all identified increased concentration of newspaper ownership as a problem and proposed measures to solve it. Formed in the 1980s, the Competition Bureau took action against a local newspaper monopoly in Vancouver in the early 1990s but has been ineffective since. This study charts the historical progress of newspaper ownership concentration in Canada and calculates that Postmedia now publishes 37.6 percent of Canadian paid daily newspaper circulation and owns fifteen of the twenty-two largest Englishlanguage dailies. That includes 75.4 percent in the three westernmost provinces, where Postmedia owns eight of the nine largest dailies. Possible explanations for a lack of outcry include the company’s use of the “death of newspapers” meme as justification and the fact the deal’s effect was felt mostly in Western Canada, far from the corridors of power.
Politics of Bricolage and the Double-Sided Message of the LEGO Movie
Authors: Grobovaite Dalia
Published: July 2022

With the release of The Lego Movie in 2014, Frankfurt School’s critical theory once again finds an application in the contemporary media landscape. Its main postulates articulated by Theodor Adorno and Max Horkheimer have never lost significance and relevance. New media products provide a convenient platform to engage in the discussion and reinforce some of the most influential critiques of the culture industries. Although with less negative dialect, the paper approaches Horkheimer’s and Adorno’s critique of mass culture in a contemporary media landscape referencing their most influential work of critical theory - Dialectic of Enlightenment. The paper carefully examines the script of The Lego Movie and producers’ interviews and relates those to the critical concepts of the culture industries. From the onset, The Lego Movie brings up a few controversial messages. First, the idea of creativity and imagination appears to be limited to the use of the brick, namely the Lego brick. Secondly, although the basic maxim of the movie is the promotion of self-identity and individuality, the development of these personal traits through the storyline is debatable. Finally, the producers’ aim to criticize American mass culture and the culture industry is dubious as much as their claim to have no intention for the movie to serve as a commercial. The paradox of the latter is poignant since the critique of mass culture is embedded in the product of the same culture — the medium of the screen — the movie. The Lego movie uses a powerful medium to convey the message of the consumer culture – the colorful brick, which is easily recognized by kids all over the world. It is arguable whether the medium intensifies the messages disseminated through the movie. A massive increase in the sales of Lego sets after the movie’s release may suggest an affirmative answer.

Published: July 2022

Autism is a developmental disorder that usually occurs in children. This disorder is characterized as an inability to interact with others in the form of a language disorder indicated by delayed language acquisition. Meanwhile, as humans, we are social creatures who definitely need help from others. Social interaction is key for a human being to adapt to his environment. Without interaction, there is no such thing as communal life. This study aims to determine the model of guidance for autistic children used in the Sekolah Khusus Taruna Al-Qur'an to improve students' social interaction skills. This study uses descriptive qualitative research methods. Data was collected by means of observation, in-depth interviews, and documentation. The result of this research is that the Sekolah Khusus Taruna Al-Qur'an provides guidance in the form of speech therapy which is handled by competent therapists in their fields, and also guidance in the classroom using structured learning methods with a model of 1 or 2 students 1 teacher. Furthermore, after being given guidance, students show good changes, namely starting to focus on eye gaze and also the emergence of an understanding of how to convey desires or feelings appropriately. Obstacles in this guidance process are the variety of parenting styles of each student, unmaintained eating patterns, and limited infrastructure.
Online Path Planning of Mobile Robots Based on African Vultures Optimization Algorithm in Unknown Environments

Published: July 2022

Autonomous mobile robots developed using metaheuristic algorithms are increasingly becoming a hot topic in control and computer sciences. Specifically, finding the shortest root to the goal and avoiding hurdles are current subjects of autonomous mobile robots. The main drawbacks of classic methods are the incapacity to move the robot in a dynamic and unknown environment, deadlock in a local minimum and complicated environments, and incapacity to foretell the speed vector of obstacles and non-optimality of the route. This article exhibits a recent path planning approach that utilizes the African Vultures Optimization (AVOA) for navigation of the mobile robot in static and dynamic unknown environments with a dynamic target. The proposed online optimization approach is used in three different environments including an environment with unknown static obstacles, an environment with unknown dynamic obstacles, and an environment with a dynamic target. The proposed approach can solve a local minima problem in the environment with static obstacles. The online optimization method is performed using two phases which are the sensors’ reading phase and the path calculation phase and the results are given based on computer simulation in different unknown environments. A comparative study was conducted between the suggested algorithm and two other algorithms and the results showed that the AVOA algorithm was better in avoiding obstacles successfully including the local minima situation. Finally, the average enhancement rates in the path length compared with the Adaptive Particle Swarm Optimization (APSO) and the Hybrid Fuzzy-Wind Driven Optimization (WDO) are 2.21% and 1.02207%, respectively.
