Authors: Wang Yahui , Yi Lingzhi , Zhu Jiang , Liu Jiangyong , Wang Shitong , Liu Bo 
Published: October 2022

Background:
Accurate power load forecasting is of great significance in ensuring power load planning, reliability and economic operation. The traditional power load is easy to be affected by climate, environment, date type and other factors, resulting in the problem of poor forecasting accuracy. Therefore, it is necessary to study power load forecasting.

Objective:
Through machine learning, dimension reduction method and intelligent optimization algorithm, the accuracy of load forecasting is improved

Methods:
In order to fully extract load information and improve the accuracy of short-term load forecasting for campus electricity, an improved combination of orthogonal dimensionality reduction and Bilstm is proposed to optimize the hyperparameters in BiLSTM using an improved gray wolf algorithm. Firstly, using the advantages of principal component analysis (PCA) and Locality Preserving Projection (LPP) to maintain the global and local structure of the data, respectively, the Orthogonal PCA-LPP（OPCA-LPP） dimensionality reduction method is proposed to reduce the dimensionality of the original multidimensional data. Finally, the dimensionality-reduced data is used as the input of BiLSTM and optimized by the improved Gray Wolf algorithm, which can enhance the prediction capability of the model and thus achieve accurate prediction of short-term electric load.

Results:
The Mae and RMSE of this paper are 1.6585 and 1.7602 respectively. The results show that the method proposed in this paper is reasonable

Conclusion:
This method is applied to power load forecasting. The comparative experimental results show that this method reduces the dimension of data input, simplifies the complexity of network input data, and improves the accuracy of load forecasting. Compared with other methods, it can effectively improve the accuracy of load forecasting, and provide a basis for formulating reasonable power grid operation mode and balanced dispatching of power grid.

Published: October 2022

SUMMARY
Staff auditors frequently email clients to conduct evidence inquiry. However, little research has examined how characteristics of email communication impact auditors’ assessments of evidence. We experimentally investigate whether two characteristics of email communication, client response time and message processing fluency, influence auditors’ judgments. We find that auditor skepticism is reduced when the client provides a more fluent email response compared with a less fluent response in a moderate response time. In addition, auditor skepticism is reduced when the client provides a more fluent email response in a moderate response time versus in an immediate response time. Our results suggest that if client management takes their time to respond to an auditor’s email, then this may reduce auditor skepticism, especially if the client composes a fluent response. These findings have audit quality implications because the same client information provided via email can be perceived differently depending on other client communication characteristics.

Published: October 2022

Introduction. One of the commonly used methods for assessing the dynamic characteristics of a material is the Taylor test, which establishes the relationship between the dynamic yield strength of a cylindrical sample material and its length after hitting a non-deformable barrier. The purpose of this work was to study the microhardness and determine the dynamic yield strength of copper samples for various impact velocities in the Taylor test.Materials and Methods. Experiments were carried out with cylindrical copper (M1) samples. The throwing conditions were selected on the ballistic stand, which provided the speed of the sample in the range of 150–450 m/s at the exit from the barrel. After the impact, the microhardness of the samples in the section plane was measured. The calculation of the dynamic yield strength was carried out according to the classical Taylor formula.Results. Experimental data are presented for cylindrical copper samples upon impact on a rigid wall with velocities in the range of 162–416 m/s, including configurations and sizes of images before and after impact. Microhardness distributions in the axial section of the samples were obtained. For each sample, the dependences of the averaged values of microhardness were constructed, which made it possible to identify four areas of deformation of the samples (the area of elastic deformations, plastic deformations, intense plastic deformations, the area of the material undergoing destruction) and determine their sizes. The dynamic yield strength of copper in the studied range of impact velocities was calculated.Discussion and Conclusions. The values of microhardness in the entire considered region and for all studied impact velocities exceeded the initial value. There was a significant increase in the value of the dynamic yield strength compared to its static value. The correlation of the maximum averaged values of microhardness and dynamic yield strength, which grew with increasing impact velocity, was identified.

Преподавание в школе, возможно, является одной из самых стрессовых профессий, которая ежедневно ставит перед учителями многочисленные задачи. Источники стресса в педагогической деятельности уникальны для каждого учителя, но в целом относятся к организационному, межличностному или личному уровням. Использование той или иной стратегии совладания со стрессом зачастую обеспечивается ресурсами психики, которые расширяют зону деятельности человека, помогают преодолевать трудности, достигать цели. В исследовании принял участие 101 педагог средней общеобразовательной школы. При обработке результатов использовался корреляционный, структурный, дисперсионный и сравнительный анализы. В целом педагоги демонстрируют умеренное использование всех стратегий совладания со стрессом. Менее опытные педагоги справляются со стрессовыми ситуациями с помощью социальной поддержки, а более опытные используют положительную переоценку. Психологическая структура совладающего поведения педагогов оказывается высокоразвитой, в ней образуются связи различного уровня значимости. Базовыми копинг-стратегиями оказываются дистанцирование и самоконтроль. Определена роль некоторых личностных ресурсов совладания со стрессом у педагогов: жизнестойкости и ее компонентов, личностной тревожности, интернального локус-контроля, самооценки и эмоциональной устойчивости.
Teaching is one of the most stressful professions, and it poses numerous challenges to teachers on a daily basis. Sources of stress in teaching activities are unique to each teacher, but generally refer to organizational, interpersonal, or personal levels. The use of this or that strategy of coping with stress is often provided by the resources of the psyche, which expand the zone of human activity, help to overcome difficulties, achieve the goal. At various stages of the study, a total of 101 secondary school teachers took part in it. Correlation, structural, and comparative analyses were used in processing the study results. In general, educators demonstrate moderate use of all coping strategies. Less experienced educators deal with stressful situations with social support, and more experienced ones mobilized other strategies (positive reassessment). The psychological structure of the coping behavior of teachers turns out to be highly developed; connections of various levels of significance are formed in it. The basic coping strategies are distancing and self-control. The role of some personal resources of coping with stress in teachers has been determined: resilience and its components, personal anxiety, international locus of control, self-esteem and emotional stability. Personal qualities that influence coping strategies are a resource of predominantly avoidant and maladaptive coping strategies.

В статье представлены результаты исследования роли различных видов рефлексии в регуляции психических состояний студентов в ходе учебной деятельности. Показано, что современные исследования в данной области носят фрагментарный характер и не раскрывают целостного механизма ментальной регуляции психических состояний человека. В рамках данной проблемы особо выделяется роль рефлексии как важнейшей детерминанты в регуляции состояний, как опосредующего звена в выборе оптимальных способов и приемов регуляции состояний. Исследование проводилось в группах студентов психологов и математиков 4-го курса, а вся совокупность испытуемых была разделена на три группы по уровню выраженности рефлексивности на низко-, средне- и высокорефлексивных студентов. В результате исследований было установлено, что влияние рефлексии на операциональные средства саморегуляции выше при более напряженных формах учебной деятельности. Выявлены ведущие формы рефлексии во взаимосвязи со способами саморегуляции психических состояний на лекциях, семинарах и экзаменах. Результаты исследований позволят в дальнейшем раскрыть значение рефлексии в целостном регуляторном процессе жизнедеятельности субъекта.

Published: October 2022

Применение информационных технологий в процессе обучения уже стало обыденностью, но постоянно появляются какие-то новые инструменты, помогающие педагогу и обучающимся. Чтобы образование действительно соответствовало запросу современных реалий, необходимо непрерывно модернизировать формы и методы обучения. Одним таким весьма актуальным помощником в обучении математике является система динамической математики (СДМ) GeoGebra. Математика всегда занимала особое место среди наук хотя бы потому, что она весьма абстракта и сложна для восприятия. Просто заучить формулы и определения недостаточно, а точнее сказать, бессмысленно. Нужно понимать суть и уметь пользоваться полученными знаниями. Поэтому имеется необходимость в наглядности математических понятий для более подробного их рассмотрения и осознания, для чего и используются СДМ. Также стоит подтвердить целесообразность их применения. Цель данной статьи заключается в предоставлении результатов исследования влияния использования среды GeoGebra Classroom на качество обучения на примере темы «Комплексные числа», изучаемой студентами колледжа в курсе высшей математики.
The use of information technology in the learning process has already become commonplace, but new tools are constantly appearing to help the teacher and students. In order for education to really meet the demand of modern realities, it is necessary to continuously modernize the forms and methods of education. One such highly relevant assistant in teaching mathematics is the Dynamic Mathematics System (DMS) GeoGebra. Mathematics has always occupied a special place among the sciences, if only because it is very abstract and difficult to understand. Just memorizing formulas and definitions is not enough, or rather, it makes no sense. You need to understand the essence and be able to use the knowledge gained. Therefore, there is a need for the visibility of mathematical concepts for their more detailed consideration and understanding, for which DMS are used. It is also worth confirming the feasibility of their use. The purpose of this article is to present the results of a study of the impact of using the GeoGebra Classroom on the quality of education on the example of the topic “Complex Numbers” studied by college students in the course of higher mathematics. It was revealed that the use of Dynamic Mathematics Systems in classroom and homework has a positive effect on student’s academic performance.

Authors: Tannoury Jessica 
Published: October 2022

Organizational culture is well-documented in the literature for its impact on company performance and its role in creating competitive advantages for companies. Organizational culture has long been acknowledged as a significant aspect in the analysis of organizations in many situations. An organization's culture serves as an integrated way of controlling members' behavior and as a particular catalyst for the organization's growth and development culture is an essential part of every facet of organizational life. As a result, a company's culture shapes how people think, work, and feel about their job and the business as a whole. Sampled respondents were surveyed with the use of a survey tool. A questionnaire served as the tool. Using the instrument ensured that data was collected in a consistent manner. The six sections of the survey were designed to answer the research questions. The study's target demographic was the Premium Shopping Center's 500 workers. A study's sampling frame is a list of all the research population's components that will be taken into account throughout the investigation. There are 11 divisions within the corporation, with four of their divisions situated in Beirut. The list of 500 workers of Premium Shopping Center served as the study's sample frame. However, only 250 respondents answered the questionnaires. Likert scale questions were used for the closed-ended questions. To elicit even more information from the participants, open-ended questions were used. The research demonstrated that a cooperative work environment had a positive impact on performance because of the existence of a supportive work environment. The research found that psychological safety is fostered by helpful and trustworthy interpersonal interactions as well as supportive management.
Assessing The Costs and Benefits of Adopting Solar Energy on The Bottom Line in The Lebanese Foodservice Industry: Owners’ And Managers’ Perspectives
Authors: Wazni Imad 
Published: October 2022

Electricity provides various benefits to the economy, including the availability of electrical gadgets and improved lighting. Therefore, the loss of power is seen as a major setback, particularly in Lebanon. It would be incredibly challenging to provide modern energy such as electricity to light a room, cook a meal, or operate a restaurant. Restaurants in Lebanon either lack access to or cannot afford to pay for reliable sources of electricity. This means that individuals in Lebanon are able to pay for and make use of the newly accessible electricity. Convenience sampling is used when a researcher has ready access to the population from which to draw a sample. A wide range of managers participated in this poll. In Lebanese settings, only 300 out of 350 requested survey participants showed up. People who care about the environment are more likely to buy renewable energy. In general, advocates for the use of renewable energy sources tend to be those who are environmentally sensitive and who feel a personal commitment to safeguarding the earth. Customers' concern for the environment may affect their purchasing decisions, but this effect is likely to be moderated by other factors. Strong environmental values improve a consumer's tendency to purchase eco-friendly goods. Managers who care about doing the right thing are more likely to buy environmentally friendly products. In addition, ecoaware executives are more likely to invest in sustainable power plants. Customers that care about the environment and are knowledgeable about environmental issues are more likely to make purchases that are good for the planet.
Introduction to Modelling the Correlation Between Grain Sizes of Feed Material and the Structure and Efficiency of the Process of Co-Rotating Twin-Screw Extrusion of Non-Flammable Composites with a Pla Matrix

Abstract
Co-rotating twin-screw extrusion is an energy consuming process that is generally not fully optimised to a specific polymer. From the point of view of the efficiency of the extrusion process, the starting material should be characterised by small grain sizes in comparison to the screw channel area, small surface area to volume ratio and small internal friction between the pellets. To develop a model describing the effect of polylactide (PLA) grain size on the extrusion efficiency, a series of experiments with a twin-screw extruder were carried out during which the energy consumption; torque on shafts and temperature of the melt on the extruder die were monitored. As feed material, both the neat PLA with different grain sizes and the PLA with expandable graphite fillers and phosphorous-based flame retardants were used. Morphology and dispersion quality of the composites were examined using scanning electron microscopy (SEM); flammability, smoke production, mass loss and heat release rates were tested using cone calorimetry; and melt flow rate was determine using a plastometer. Moreover, the thermal properties of the obtained composites were determined using differential scanning calorimetry (DSC). The results show that the choice of the starting material affects both the efficiency of the extrusion process and the flame retardancy properties of the composite materials.
