Pineapple is one kind of fruit that contains a lot of nutrition. The waste from residual pineapple processing is called bromelain. Bromelain contains polymer complex in the form of organic sources from nature if it could be decomposed properly. One way to exploited bromelain is by composting. Composting is done with the help of fungi of Trichoderma sp. to speed up the decomposition process. The resulting compost is aerated to increase the nutrients and form a further decomposition process in the soil. The research was carried out from January till March 2021 in the Microbiology Laboratory Biology, Faculty of Mathematics and Science, University of Lampung. The parameters of this research are the content of chlorophyll and the number of leaves. This research used a completely Randomized Design with 7 treatments that are A1 (24 hours of mixed bromelain), A2 (48 hours of mixed bromelain), A3 (72 hours of mixed bromelain), A4 (24 hours of pure bromelain), A5 (48 hours of pure bromelain), A6 (72 hours of pure bromelain), and A7 (control). Based on this research the value of the highest chlorophyll A on A6 treatment is 0,655. A value of the highest on chlorophyll B on A6 treatment that 0,429. The highest total chlorophyll on the A6 treatment is 1,048. Based on this research the A4 treatment has the highest average number of leaves compared to other treatments.

Abstract
A driving wheel is a part of a tractor, which transmits forces from a tyre to the ground. Therefore, it affects the tractor movement and the pulling of an implement. The paper is aimed at a tractive performance evaluation of special driving wheels based on drawbar pull at 100%-slip. These wheels consist of steel spikes to be applied in the base or working position. The design is characterized by the spikes placed in a tyre-tread pattern. The rubber lugs of the tyre are higher than spikes, therefore, they are not in contact with the ground in the base position. The spikes in the working position exceed the tyre diameter to be in contact with the ground. Tests were performed on a grass plot at a relatively low soil moisture. The spike tyres were compared with the standard tyres using a sub-compact tractor. An increase in drawbar pull reached a statistically significant value of 15.9% in the 2nd gear and 16.7% in the 1st gear.

Published: June 2022

Abstract
A series of novel poly(α-methyl β-alanine-b-lactone)s were prepared by a combination of hydrogen-transfer polymerization (HTP) of methacrylamide (MAm) and anionic ring-opening polymerization (AROP) of β-propiolactone (BPL), β-butyrolactone (BBL), and δ-valerolactone (DVL). For this purpose, poly(α-methyl β-alanine) (PmBA) having a living anionic end-group for a further extension was obtained via HTP of MAm. The anionic end-group on PmBA chains were used as initiation sites for AROP of BPL, BBL, and DVL. Fourier Transform Infrared Spectroscopy (FTIR) and Proton Nuclear Magnetic Resonance Spectroscopy (1H-NMR) confirmed the existence of both ester and α-methyl β-alanine (mBA) units in the final products. MALDI-MS analysis revealed that the poly(α-methyl β-alanine-b-lactone)s with average molar masses of several thousand g·mol−1 were obtained. DSC and TGA thermograms of each copolymer showed that the copolymers comprised the mBA and the corresponding ester units.
Optimal control of a contact problem with slip dependent friction
Authors: Kasri Abderrezak , Touzaline Arezki 
Published: June 2022

Abstract
The aim of this paper is to study a frictional contact problem between an elastic body and a foundation. We focus on the optimal control of the model which consists of acting with a control on a portion of the boundary of the body and leading the stress tensor as close as possible to a given target. We state an optimal control problem for which we establish an existence theorem of the solution. We then introduce a sequence of regularized problems depending on a positive parameter α and we study the convergence of the sequence of the solutions when the parameter α tends to zero. Finally, an optimality condition is established for this problem.

Intangible Assets, Goodwill and Earnings Management: Evidence from France and the Uk
Authors: Kimouche Bilal 
Published: June 2022

Abstract

Research background: The literature has argued that accounting for intangible assets and goodwill provides a wide range for managers to manipulate earnings.

Purpose: This paper aims to investigate the impact of accounting treatment of intangible assets and goodwill on earnings management.

Research methodology: The study included 115 French companies and 100 UK companies, during 2011–2019, employing multiple regression, where earnings management was measured through discretionary accruals; while accounting for intangibles and goodwill was divided into the capitalization and decapitalization of intangible assets, recognition and derecognition of goodwill, and depreciation and impairment of intangible assets and goodwill.

Results: According to the results, accounting for intangible assets and goodwill has an impact on earnings management, while it is used differently between French and UK companies. In France, companies employ intangible assets capitalization to manipulate earnings, while UK companies use intangible assets capitalization and goodwill recognition.

Novelty: This study provides supplementary evidence for standards setters, managers, and auditors about the contribution of accounting for intangible assets and goodwill in the quality of financial reporting and explores the new tools and practices of earnings management.
Modeling Distress in US High Yield Mutual Funds Before and During the Covid-19 Pandemic
Authors: Szymczyk Łukasz , Van Horne Richard , Perez Katarzyna 
Published: June 2022

Abstract

Research background: In March 2020, when the US financial markets were in the grip of the COVID-19 crisis, the Fed instituted various policies and programs to alleviate stress in financial markets. One such program involved the Fed purchase of securities and ETFs in certain market segments, including high yield bonds. This buying action inspired investors to join the Fed (or front-run the Fed) in the high yield bond market, resulting in the tightening of spreads in that market to historically tight levels.

Purpose: In this research we investigate whether investors could have seen any signs of higher liquidity risk in US high yield mutual funds since the beginning of COVID-19 pandemic and avoid it. Theoretically, funds with heightened liquidity risk should have higher historical returns (adjusted for interest rate risk and credit risk) because borne risk requires return as compensation. But because of the unusual market conditions during the COVID-19 pandemic investors could look inside funds (to see what bonds the funds owned) and then avoid funds with holdings known to be less liquid.

Research methodology: The study is based on data on US mutual funds from the Morningstar Direct database. The authors made a serial correlation model with an AR(1) process and the lagged effects model vs CAPM model to measure two proxies for liquidity risk for each US high yield mutual fund in our fund universe, in order to identify those funds at particular risk for portfolio illiquidity since the beginning of the COVID-19 pandemic.

Results: it is found that the proposed measures may be an effective tool for selecting high yield funds against liquidity risk. Therefore, they should be considered by investors or analysts as a practical tool to identify funds that might be illiquid.

Novelty: The study focuses on the liquidity risk in US high yield bond mutual funds before and after the outbreak of the COVID-19 pandemic, which was a crisis situation with implications for liquidity risk. The methods used and results achieved may be a basis for studies of other types of funds and markets outside the USA.

Authors: Pesotska Yuliia Pesotska 
Published: June 2022

The concept of internally displaced persons (IDPs) in today’s conditions is highlighted in the article. The article reveals the features of providing assistance to such persons both during active hostilities and in safe places. Thus, it considers the concept of first aid, which is a necessary step to overcome post-traumatic stress disorders and other disorders, as well as part of the rehabilitation process.
The concepts of «social rehabilitation» and «social adaptation» are outlined, namely internally displaced persons. It was determined that social rehabilitation and social adaptation are interdependent and complementary processes that have certain common goals and methods and technologies to achieve these goals.
Recommendations for the provision of social services for IDPs that will promote social rehabilitation and social adaptation are described. The stages of the adaptation process underlying J. Gullahorn's theory of assessing the adaptation strategies of IDPs are described.
The means of museum activity which can be used during the process of social rehabilitation and social adaptation of IDPs are presented. Among them the author(s) elucidate the project «Cultural-recreational-tourist Cherkasy region: inclusive-social 3D-map» with the support of the Ukrainian Cultural Foundation, which is designed for both offline and online use. The world museums, whose exhibits are available online are also presented.
The fact is taken into account that in order to cope with this challenge an interdisciplinary team is needed, able to create a set of measures that will contribute to the psychophysiological state of the individual. That is why this article will be useful for medical professionals, psychotherapists, psychologists, rehabilitation specialists and social workers.
Actual problems of accountability and responsibility of officials of international judicial institutions
Authors: Smirnov Viktor Vyacheslavovich 
Published: June 2022

Currently, there are a number of problems of legal norms in the work of international judicial institutions, which are considered in this study. The object of scientific research is the legal basis for regulating the accountability and responsibility of officials of international courts and tribunals. The subject of the study is a general overview of the issues of accountability and responsibility of officials of international judicial institutions, and especially judges. The author examines in detail the existing problems of legal norms related to the above issues. The paper defines the terms "responsibility", "accountability", "official", examines the existing types of responsibility of officials of international justice bodies, procedures for bringing to justice. В Accountability of officials of international judicial institutions is extremely important, since international courts and tribunals in their activities often exceed the powers provided for them, introduce new "norms" of international law that contradict generally recognized norms, and sometimes the Statutes of these institutions. The paper also presents options for possible solutions to problems, in particular, the author suggests working out a transparent legal mechanism for holding officials accountable, providing the general public with access to statistics on the effectiveness of judges of international courts and tribunals, and continuing to further improve the "transparency" of both the judicial process and all activities of international judicial institutions.

Published: June 2022

По своему содержанию действующие стандарты высшего экономического образования надо считать стандартами первого поколения с последующей разработкой стандартов второго, третьего и последующих поколений, в которых найдут отражение современные и будущие тенденции развития образования, а именно: ее диверсификация, последовательность, непрерывность, интенсификация образовательных процессов и их информатизация. Развитие стандартов экономического образования предусматривает: модернизацию отраслевых стандартов высшего образования разных образовательно-квалификационных уровней; внедрение в учебный процесс форм и методов, обеспечивающих усиленную его ориентацию на практическую или научную подготовку студентов в зависимости от образовательного квалификационного уровня. Образование является основой социального, политического, экономического, духовного и культурного развития общества. Одним из важных стратегических задач высших учебных заведений России является интеграция в единое европейское образовательное и научное пространство. Анализ практической деятельности и теоретических трудов кооператоров и педагогов свидетельствует, что как западноевропейские ученые, так и отечественные педагоги указывают применение методов психологических исследований в профессиональной ориентации, развитию экономического образования, приобретения новых профессий как фактора социальной защиты в новых социально-экономических условиях.
According to its content, the current standards of higher economic education should be considered the standards of the first generation, followed by the development of standards of the second, third and subsequent generations, which will reflect current and future trends in the development of education, namely: its diversification, consistency, continuity, intensification of educational processes and their informatization. The development of standards of economic education provides for: modernization of industry standards of higher education of different educational and qualification levels; introduction of forms and methods into the educational process that ensure its enhanced orientation to practical or scientific training of students, depending on the educational qualification level. Education is the basis of social, political, economic, spiritual and cultural development of society. One of the important strategic objectives of higher education institutions in Russia is integration into a single European educational and scientific space. An analysis of the practical activities and theoretical works of cooperators and teachers shows that both Western European scientists and domestic teachers indicate the use of psychological research methods in professional orientation, the development of economic education, the acquisition of new professions as a factor of social protection in new socio-economic conditions.

Affordances in Educational Technology: Perceptions of Teachers and Students in Oman
Authors: Al-Maawali Wafa 
Published: June 2022

Aim/Purpose: This study of affordances in educational technology focuses on how the self-perceptions of teachers influence the creation of educational opportunities and how these are received by learners.

Background: It is important to explore the affordances offered by teachers, when using educational technology, from the perspective of their students. Within this topic, the interface of the educational technology affordances with the two agents—teachers and students—has often been neglected. Hence, the learning possibilities in educational interactions for the learners cannot be separated from the interactional possibilities created by teachers. The extent to which teachers can create opportunities to address their students’ needs, while effectively conveying the value of these opportunities to their students, is likely to impact on how well these affordances for learning and collaboration are utilised.

Methodology: A survey that includes two questionnaires was used. The questionnaires were circulated to 102 teachers and their 354 adult students in six higher education institutions in Oman. The questionnaires were analysed by SPSS Amos v20 for statistical measures such as mean, standard deviation, and correlation.

Contribution: The study contributes to the field of e-learning because it demonstrates that the affordances offered by teachers for e-learning have an impact on the possibilities for students to engage. Both affordances were found to be highly correlated statistically. Further, teachers were found to primarily use the lowest level of engagement for online tasks, requiring low levels of cognitive challenge and social involvement from the learner.
Findings	The results indicate a low to medium level of self-directed learning that significantly correlates with perceptions of teaching possibilities for learning interactions.

Recommendations for Practitioners: Teachers are encouraged to vary approaches to student engagement in online teaching materials such as enhancement, additional engagement opportunities, and extension so that students are encouraged to use different cognitive abilities and capabilities to engage in social interactions.

Impact on Society: This study presents a strong recommendation with regards to extending the online affordances towards social interactions of learning beyond the boundary of the classroom.

Future Research: Further studies on e-heutagogy and affordances of both teachers and students are needed. The effect of teachers created opportunities on students learning actions is an area that grants further investigation.
