Gendered and Gender-Neutral Character of Public Places in Algeria
Authors: Rahmani Lyes , Messaoudene Maha
Published: July 2021

This article aims to determine whether Algerian public spaces are gendered or gender neutral and to deduce the place of women in this type of hedonistic aesthetic consumption space. A non-probability sample of 363 individuals allowed us to collect the necessary data on the basis of an experiential scale designed for Algerian public spaces. This scale offers us the possibility of measuring their spatial and phenomenal experiential tendency. In other words, it allows us to evaluate the potential of their sensorial, relational, emotional, cognitive, behavioural spaces, their urban environments and their spirits of the place. This scale has undergone the tests of reliability and validity laid down by Churchill. It has also undergone the latest generation confirmatory factor analysis (CFA) method. Due to the non-normality of the sample distribution, we applied non-parametric tests in our analysis. The Mann Whitney U tests were used to calculate and compare the indices of spatial and phenomenal segregation of public places. The results revealed the gendered or gender-neutral nature of the three public places with their respective mapping. In the end, on the basis of the cultural dimensions of Hofstede, we were able to get to know the populations of the cities in our case studies that require urgent awareness-raising action. This promotes gender equality and especially the right of women to use and occupy hedonic public spaces without any conditions or prejudice.
Planning of the Interregional Tourist Route in the Urals
Authors: Zyrianov Aleksandr I. , Zyrianova Inna S.
Published: July 2021

The article aims to attract the attention of geographers to the development of technology for the design of tourist routes. The world and Russian experience of designing long interregional tourist routes is considered. The authors’ approaches to route design are illustrated by the example of the Urals. Interregional tourist routes in Russia are actively developed with the support of the government. They are initiated by interacting regions and especially federal districts. Interregional routes are tours covering several adjacent regions or regions that are close not territorially, but thematically in tourist aspects. Such routes are quite different, but they have mainly cultural and informative goals as well as an excursion, transport and sometimes cruise style. Among all the interregional routes, the ‘Golden Ring’ and the ‘Volga-Kama’ river cruises are exemplary, among which the ‘Moskovskaya krugosvetka’ stands out due to the uniqueness of the ring shape of the route. The geographic features of the Urals are at the heart of the logical decisions for the preparation of the interregional tourist project ’The Great Ural Route’. The Urals have attractive, image, logistic and other opportunities for organising a large tourist route. A route should be developed for residents of the country and foreign guests, which will introduce the most striking and characteristic objects of the macro region as a whole. Moreover, the annular shape of the route is most preferred. It is advisable to lay the route in most of the Ural regions. It should include the main cities, landscapes of different natural zones, the most significant excursion sites and distinctive territories. Geographic route design technologies make it possible to make them relevant for a long time.

Published: July 2021

This paper present the results of our project to develop the preliminary design of a jet trainer plane (JTP) with a two-person crew, the base version of which is intended for cadet training. We first consider the assumptions and requirements for the new aircraft, and review the parameters of existing aircraft designs in the similarly-purposed class. Next we argue for certain design choices, regarding the aircraft layout, cockpit configuration, wing location and wingform, tail scheme, and powerplant. The resulting aircraft design is calculated to have a maximum flight speed of 940 km/h, a ground-level rate of climb of 100 m/s, and a range of 1130 km. The plane’s take-off mass is calculated, in three approximations, at 2264 kg. Lastly we present the training plane’s geometrical parameters, general view, and master geometry.

FROM CRITICAL THINKING TO REFLECTION TO CITIZEN ENGINEERS
Authors: Johnson E. Anne
Published: July 2021

What does it mean to be a “responsible engineer”? The question has been asked throughout history, including during times that were fraught with challenge, but the problems awaiting engineering students in Canada in 2021 are arguably unprecedented in their complexity. Technologically difficult problems resulted in recent advances such as the World Wide Web and 5G mobile communications, but today’s challenge derives not only from the global scale of man-made environmental problems and their impacts, but from lack of agreement around appropriate mitigation strategies and on the need to act at all. The engineering students of today must develop solutions to problems that have newly acknowledged and highly contentious human factors. In the Canadian context, new policy is emerging from Canada’s recognition that it must reconcile the harms of past policies towards Indigenous peoples. This recognition has created a discourse around equity that will shape the landscape in which graduates will practice. In preparing young engineers to navigate technological and social complexity, and to equip them to find personal fulfillment in an uncertain landscape, a reinvigorated emphasis on critical and relational thinking is required. In 2019 and 2020, students in a fourth-year class in Sustainability, (which includes a study of law, policy, and sustainability reporting metrics) participated in multiple group exercises that asked them to explore multiple facets of problematic or politically current issues. These learning activities sought to support a transformative learning experience in which students would come to recognize their ability to contribute as citizens to the development of responsible public policy. In these exercises they examined opposing positions and assessed the strengths, weaknesses, opportunities and risks, associated with each. That there was no RIGHT conclusion was emphasized. The only criteria for assessment was depth of exploration and logical chaining of evidence. Students learned about cultural perspectives from an Indigenous educator, and as they explored the diversity of viewpoints around the question of pipeline expansion in Canada. A final exercise asked students to reflect on the meanings of responsible policy and practice and how they would operationalize sustainability thinking.
GRADUATE ATTRIBUTE MANAGEMENT: MAPPING UNIVERSITY GENERIC ATTRIBUTES TO THOSE OF THE CANADIAN ENGINEERING ACCREDITATION BOARD

Published: July 2021

After 2009, accredited Canadian engineering schools began to develop processes to map the Canadian Engineering Accreditation Board-Graduate Attributes(CEAB-GAs) to their curriculum and integrate ways to measure them. At around the same time, several Canadian universities embarked on a process to identifytheir own University-wide Graduate Attribute (UGAs).  UGAs are assumed to be applicable across study disciplines; i.e. the university experience as a whole.To address the need to assess students on the basis of the CEAB GAs and the UGAs in the Faculty of Engineering and develop the basis for an integrated graduate attribute management system, an interdisciplinary team conducted a yearlong qualitative study with the purpose of exploringthe intersection of the UGAs with CEAB-GAs. The key objectives were to develop a mapping process between the two sets and to explore management strategies for assessing both sets of graduate attributes. Two independent teams performed the mapping exercise using a sequential mixed methods study design. A qualitative exploratory mapping study was followed by a quantitative aggregation of the mapping results. Integration of the qualitative and quantitative study results was completed as part of the interpretation of the results. Both forward and backward mapping took place. Results demonstrated that, although generic, UGAs may not necessarily capture specific professional program graduate attributes such as the CEAB-GAs. The study also highlighted the need for more revisions and updates of UGAs by including various stakeholders who can substantially contribute to implementation and assessment of UGAs.

PRACTICAL INTEGRATION OF SUSTAINABILITY INTO ENGINEERING
Authors: Beneteau Donna , Chovan Karen , Gauthier Sarah
Published: July 2021

The broad terminology around sustainability is an excellent catalyst for discussing the technical and social impacts of projects in an engineering classroom and for improving decisions made in team-based designprojects. When an exploratory hands-on methodology is applied, the introduction of the various aspects associated with sustainability allows instructors to engage students to SEE (identify) Social, Economic, and Environmental impacts and quantify the relevancy of generic criteria to specific projects. The P5TM Impact Analysis tool (GPM Global) was used to identify relevant criteria for ranking design projects. Whereas the methodology is reproducible, the decisions made by students can vary when there is no clear answer. With a range in results, the instructors can then have the students perform additional analyses to reflect on the complexity of ranking alternatives and to view the results based on various circumstances. The outcome is that the students gain a broader understanding of how SEEing different perspectives matters and addsvalue to the decision making process.
LIVE-STREAMING IN MECHANICAL ENGINEERING: AN INNOVATIVE APPROACH TO REMOTE LAB DELIVERY
Authors: Stumpf Calynn , Parker Anita
Published: July 2021

In-person laboratories in undergraduate engineering provide students with tactile opportunities to build career-related skills, which are reflected in the graduate attributes of program accreditation criteria. TwoMechanical Engineering laboratory courses at the University of Alberta implemented live-streaming amidstthe abrupt and indefinite move to online learning due to the COVID-19 pandemic over the Fall 2020 term. A highly motivated and technically competent lab instructional team derived the necessary set-up of hardware, software, and personnel to implement pedagogical strategies that replicated the in-person experience with mechanical equipment as much as possible.  This innovative approach enabled students to be involved in the demonstration of experiments in real time, interacting with teaching assistants and peers to ask questions and receive feedback.  Students preferred live-streaming of labs as compared to pre-recorded videos.

Published: July 2021

Given the growth of the engineering education community in Canada, we argue that a research agendathat reflects our own identity and interests is needed. To start this conversation, we conducted a content analysis of the 2019 CEEA-ACEG conference proceedings to investigate the implicit Canadian research agenda for engineering education. We analyzed five characteristics: publications’ stream, level of collaboration, authors’ affiliations and, more importantly, their research topicsand areas. We found that the Canadian EER community is very practice-oriented, collaborative and that mostuniversities were represented at the conference. Also, seven main research areas were identified: Assessment,Teaching and Learning, Students, Faculty, Organizational, Engineering Education Discipline, and Philosophy of Engineering. Among these areas, Teaching and Learning is, by far, the one that received the most attention.

Published: July 2021

There are still many questions to answer regarding the implementation and ongoing use of the CEAB graduate attributes (GAs) to guide engineering education content and student progression. How well doour students know and understand the twelve GAs? Which ones do they find most important? Do the knowledge and importance of the GAs vary over the course of students’ programs, or among institutions? Do students’ definitions of an engineer reflect the GAs? How do the definitions reflect students’ evolving understanding of engineering identity? Given the similarity of purpose, philosophy, and complementarity of questions and methods regarding the student perspective on engineering, the GAs, and their development, researchers from three institutions across Canada joined forces to conduct a national study. The overarching objectives of the study are to provide insight on how undergraduate students’ engineering identities develop through the course of their programs using the CEAB GAs as a normative framework, and enable meaningful comparisons of the GAs rankings and learning cultures at the three institutions. The objectives of this paper are to present an overview of the study development, and describe the methods used to develop the French and English codebooks for analysis of the qualitative data. We discuss the disambiguation of the codes and lexicon with particular attention to the concepts of professionalism and leadership and the emergence of three inductive codes: Engineering Work, Societal Improvement, and Personal Characteristics. We close the paper with a few words on future work.

Published: July 2021

Background: Exposure to high-dose radiation is linked to an increased risk of cancer. The use of good radiation protection protocols improves the quality of education and research. The present study was aimed at assessing the knowledge of radiation safety among medical interns in Saudi Arabia.
Methodology: This cross-sectional study was conducted among medical interns in Saudi Arabia from 2019 to 2020. A cluster-multistage random sampling technique was applied in this study. The collected data were entered into and analyzed with Statistical Package for the Social Sciences software version 21.0.
Results: Among 346 participants, 64.2% were male, and 35.8% were female. In total, 38.7% of the participants had a sufficient level of knowledge about ionizing radiation-related risks. In comparison, the vast majority (76%) had never attended events and/or refresher courses on radiation protection. The knowledge score for radiation protection was classified into two levels (good and poor): poor (0 to 2), which 69.7% of the participants achieved. Chi-square tests indicated a significant association between the knowledge score and age (p < 0.01) in favor of 25 years old. There was a significant association between the knowledge score and attendance
at training events and/or refresher courses on radiation protection (p < 0.01) in favor of the participants who frequently attended the training.
Conclusion: The vast majority of interns had insufficient knowledge of radiation protection, which was related to a lack of attendance at training events.
Supping with the Devil: Belief and the Imaginary World of Multiple Myeloma Therapies Invented by the Institute for Clinical and Economic Review
Authors: Langley Paul C
Published: July 2021

Previous commentaries in Innovations in Pharmacy and other peer reviewed journals have made the case that the analytical framework, if that is not too strong a term, to support pricing and access recommendations endorsed by the Institute for Clinical and Economic Review (ICER) fails to meet the standards of normal science. By any criteria the ICER analysis is best described as pseudoscience; it fails the demarcation test between biological evolution and intelligent design. Like intelligent design it has its believers; a meme for all seasons. ICER is fully aware of the fact that it fails these standards, yet perseveres. It justifies its cost-per-QALY framework by maintaining, through unsubstantiated assertions, that it meets standards for scientific credibility; it denies the possibility of negative values and utilities which undercut completely the construction of QALYs. This is nonsense: not only does the ICER framework fail those standards, to include axioms of fundamental measurement, but also a simple rule of logic in basing its models on assumptions. ICER dogmatic adherence to simulation modeling is evidence in its latest report on multiple myeloma. The report is a charade; but unfortunately not one that is rejected by Bristol-Myer Squibb, GlaxoSmithKline, Sanofi and Amgen. Their responses to the draft evidence report points to their acceptance of imaginary simulation constructs to drive pricing decisions. Whether this reflects their unqualified acceptance of the imaginary simulation modelling to create evidence or a failure to appreciate the standards of normal science is unclear. Certainly, in this case they fail to recognize the devastating impact of believing in the use of the EQ-5D-5L preferences to create imaginary or I-QALYs. The question raised in this commentary is whether the willingness to accept the ICER analytical framework reflects a belief in the role of creating evidence, ICER style, or a willingness to accept ICER imaginary conclusions as the easy way out in negotiating prices with insurers and other payers. Accepting ICER imaginary constructs is an analytical dead end that will stifle the discovery of new facts. The question is: so what?

Published: July 2021

Much attention is currently paid to the study of the antioxidant properties of various objects – individual antioxidants, dietary supplements, medicines, liquid plant extracts. Antioxidant medicines are widely used as the main or additional correction agents in the treatment of a number of diseases. Therefore, the study and development of procedures for determining the antioxidant activity is a prospective task for today.
Aim. To determine the contribution of different concentrations of ethanol to the level of the antioxidant activity (AOA) of ascorbic acid solutions by the potentiometric method.
Results and discussion. The different ethanol content in the solution had the following percent of the contribution to the value of AOA of ascorbic acid solutions – 1.85, 3.56, 4.89, 6.76, 7.63 % for 20, 40, 60, 80, 96 % ethanol, respectively. The linearity of the procedure was proven in the range from 0.039 to 0.31 mmol/L.
Experimental part. The object of the study was solutions of ascorbic acid prepared using ethanol of different concentrations – 20, 40, 60, 80, 96 %. Potentiometric measurements were conducted by a Hanna 2550 pH meter (Germany) with an EZDO 5010 combined platinum electrode. Weighing was carried out using an АN100 digital analytical balance (AXIS, Ukraine) with d = 0.0001 g. Ascorbic acid was purchased from Sigma Aldrich (≥ 99.0 %), K3[Fe(CN)6], K4[Fe(CN)6], NaHPO4, KH2PO4 were of analytical grade.
Conclusions. It has been found that ethyl alcohol affects the change of the potential in the electrochemical cell and the level of AOA of ascorbic acid solutions. The percentage of the contribution of different concentrations of ethyl alcohol to the AOA value ranges from 1.85 to 7.63 %. The approach and the formula for calculation that take into account the effect of ethyl alcohol on the final AOA result of the test sample of ascorbic acid in a water-alcohol solutions have been proposed. The results of this study can be used in the pharmaceutical and food industries to determine, assess and control the AOA level of dietary supplements, liquid extracts, tinctures, medicines, and alcoholic beverages.

Aim. To study the indicators characterizing the epidemiological profile of the population of Ukraine concerning HIV and AIDS in the dynamics of the years.

Materials and methods. Data from the Center for Public Health of the Ministry of Health of Ukraine were used. Both general theoretical (historical, analytical-comparative, systemic, logical, etc.) and applied methods (epidemiological, mathematical-statistical, etc.) were applied.

Results. It was found that during 2015-2019 there was an increase in the rates of HIV infection of the population, both sexually and parenterally (excluding data for 2017). In 2019, the number of cases of human infection through sexual contact increased by 27.1 % compared to 2015, and via parenteral infection – by 31.4 %. The trend towards a systematic decrease in the number of children born to HIV-infected mothers during the entire follow-up period was positive. In 2019, compared with the data for 2015, there was an increase in the number of HIV-infected adults by 3.1 %, while AIDS patients, on the contrary, decreased by 11.3 %. An important fact was a decrease in the number of HIV-infected children under 18 by 27.3 % and children under 14 by 27.6 % in 2019 compared to 2015. A negative trend was an increase in the number of deaths from AIDS-related pathologies among adults in 2015-2018, as well as among children under 18 years of age in 2019 by 18.0 %. Based on the results of the analysis of the structure of HIV-infected people by age, there was a systematic increase in the proportion (%) of adults (from 81.0 % in 2015 to 86.6 % in 2019). In addition, the number of adult patients per HIV-infected child under the age of 18 was increasing (2015 – 4.27 adult patients, in 2016 – 4.98 people, in 2017 – 4.91 people, 2018 – 5.39 people, and 2019 – 6.68 people).

Conclusions. The presence of positive trends in the development of the epidemiological profile of the population of Ukraine for HIV and AIDS requires not only financial support from the state and society in the future, but also the development and implementation of the appropriate social and educational projects aimed at preventing further spread of this infection among the population.

Debt Payment Obligation postponement is an effort for creditors and debtors to settle the debts with a more efficient process. The creditor of a company consists of concurrent and separatist creditors. Based on the Supreme Court Decree Number 30/KMA/SK/I/2020 Book I on the Guidelines for the Settlement of Requests for Bankrupt and Postponement of Debt Payment Obligation of the Supreme Court of the Republic of Indonesia, the creditors who can submit Postponement of Debt Payment Obligation (PKPU) are only concurrent creditors. The separatist creditors are not allowed to submit PKPU. This is different from the Bankruptcy and the Postponement of Debt Payment Law Number 37 of 2004. Based on Law Number 37 of 2004, Creditors who can submit Postponement of Debt Payment Obligation are creditors who estimate that the debtor cannot continue to pay debts that are due and can be billed, can request that the debtor be given a postponement of debt payment, to enable the debtor to submit a reconciliatory proposal which includes offering the payment of part or all of the debt to the creditor. However, based on the Supreme Court Decree, only the concurrent creditor can submit Debt Payment Obligation’s postponement. As a result of this Supreme Court Decree, the separatist creditors cannot apply for Debt Payment Obligation postponement. Separatist creditors can propose the postponement of debt payment obligations if the separatist creditor has turned into a concurrent creditor. Separatist creditors become concurrent creditors if the collateral provided value is insufficient for the company’s obligations so that the separatist creditors can propose to be part of the concurrent creditors. By becoming a concurrent creditor, the separatist creditors can submit to be part of the peace proposal and distribute the remaining company assets.
Tort Claim under the Ship Time Charter: The Perspective of Indonesian Law
Authors: Paramita Kartika
Published: July 2021

During a cargo carriage by sea under the time charter scheme, there can be a situation where the Ship-owner of the vessel does not have a contractual relationship with the cargo owner. This situation could happen when the charterer becomes the contractual carrier under the bill of lading instead of the Ship-owner. In that given scenario, if cargo damage occurs, the cargo owner can submit a tort claim against the Ship-owner. Indonesia never ratifies an international convention in the field of carriage of goods by sea. Suppose the given scenario happens without the incorporation of the Charter party or the provision of any international convention into the bill of lading, a tort claim will become a choice for the cargo owner to ask the Ship-owner's liability. It is the purpose of this article to analyze how Indonesian laws will examine a tort claim and how the Ship-owner will construe his defense in the field of carriage of goods by sea. The writing finds that Indonesia Commercial Code provides a legal basis for a cargo owner's tort claim against the Ship-owner. However, it needs further discussion to set the relationship status among the Ship-owner, the time-charterer/contractual carrier, and the cargo owner under Indonesian laws and regulations.
Environmental Corruption Prevention Policies Through Independent Agencies
Authors: Wahab Mirnawanti , Ramadani Rizki
Published: July 2021

This article aims to explain the patterns of corruption in the environmental sector (environmental corruption) and the possibility for Independent agencies to address them. Also, to initiate a better policy and supervision against environmental corruption in Indonesia. The research was carried out based on the normative legal method (library research) towards secondary data using a statutory, conceptual, and comparative approach. The results show that the main pattern of environmental corruption involves corrupt actors in bureaucratic institutions that cause weak environmental policies and supervision. The benefit of Independent Agencies with structural and personnel independence is expected to fill the gap in the old bureaucratic management and reduce corruption. The regulatory power of such agencies can also set more stringent environmental policy and supervision. Thus, there needs to be institutional reform in the environmental authorities for future policies by establishing an independent agency. The new agency must also have the power to formulate and enact policies in environmental management and give them authority to investigate and impose sanctions. We also recommend compiling a national strategic program in the form of work synergy between independent agencies in the environmental and anti-corruption sector.

Authors: Brockmann Steffen
Published: July 2021

Este artículo se reere a cómo ha sido tratada la obra de Paulo Freire en el discursopedagógico social en la Alemania Occidental desde los años setenta. La adaptación desu obra en esa década estuvo relacionada con Ivan Illich y el Centro Intercultural deDocumentación (CIDOC) en Cuernavaca, México. Visitantes de habla alemana en elCIDOC, como Hartmut von Hentig, se interesaron por Freire. Gracias a la traducciónal alemán de la Pedagogía del oprimido en 1971, su obra se volvió accesible para unextenso público en Alemania Occidental y sus métodos fueron adoptados en distintoscampos de la pedagogía social. En este contexto hay que resaltar la adaptación de susmétodos en el enfoque situacional, un enfoque muy extendido en el campo de trabajode la educación inicial. Debido a trabajos actuales sobre Freire se ha abierto una nuevadiscusión sobre las posibilidades y los obstáculos de una aplicación de sus métodos enlos campos de trabajo pedagógicos sociales de la actual República Federal Alemana y,teniendo como trasfondo los trabajos de Boaventura de Sousa Santos, se ha hecho unareexión sobre cuál sería la contribución de la obra de Freire para Alemania.Palabras clave: Freire, Illich, enfoque situacional, eurocentrismo, epistemologías delSur.
