Vancouver School Names, 1886-2023: Continuity and Change
Authors: Gibson Lindsay , Davies Mallory
Published: June 2024

Over the past few years, controversies about commemorations, including statues, street names, buildings, and school names, have been at the forefront of public debate in Canada and around the world. In Vancouver, students, members of the public, and community groups have called for renaming various Vancouver School Board schools. Inspired by these debates, we analyzed newspapers, school board minutes and reports, census data, and various secondary sources to better understand Vancouver school naming practices between 1886 and 2023. Drawing from scholarship in critical toponymy, our research note demonstrates that Vancouver’s school names provide valuable insights into the beliefs, values, and attitudes of the people who made decisions about school names, the ways collective memory and settler identity were institutionalized in schools, and the politics of naming and renaming. Our hope is that this research will inform public debates about Vancouver school naming and renaming, and contribute to historically informed decision-making for a more just and equitable future.

Published: June 2024

The government implements various poverty alleviation policies, Ziswaf has not been utilized as an instrument of financial inclusion in poverty alleviation. This study aims to examine and provide solutions to poverty alleviation by making Ziswaf an instrument of financial inclusion. Field research with a qualitative descriptive thinking paradigm makes the Takmir community the subject of the interview and scattered mosques the main object. In addition to the OJK report, Bank Indonesia, Puskas Baznas, and KNEKS are its supporters. The results of the study found that Ziswaf's potential is very large, but the Ziswaf funds distributed have not been able to alleviate poverty. Access and availability of Ziswaf funds are still very scarce and difficult for the community to obtain, the distribution is incidental and consumptive rather than productive. Ziswaf as an instrument of financial inclusion is expected to be managed on target to alleviate poverty.

Pewarna makanan adalah bahan tambahan pangan yang ketika ditambahkan atau diaplikasikan pada pangan mampu memberi atau memperbaiki warna. Selain memiliki aroma yang khas, pandan juga dapat dimanfaatkan sebagai pewarna alami. Namun, pewarna makanan alami memiliki stabilitas warna yang kurang baik karena sifat pigmennya yang mudah terdegradasi sehingga tidak optimal dalam memberikan warna pada produk pangan. Dengan demikian diperlukan suatu produk pasta pandan yang memiliki kestabilan baik. Pembentukan kompleks Zn-klorofil diketahui dapat menjaga kestabilan warna. Penelitian ini bertujuan untuk mempelajari pengaruh ZnCl2 sebagai media ekstraksi; gum arab dan maltodekstrin sebagai bahan pengisi pada pembuatan pasta pandan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) 2 faktorial yaitu penambahan konsentrasi ZnCl2 0, 500, 750, 1000 ppm dan penggunaan variasi rasio gum arab dan maltodekstrin yakni 0:2, 1:1, 2:0 (b/b). Hasil penelitian menunjukkan bahwa penambahan konsentrasi ZnCl2 dan penggunaan variasi bahan pengisi berpengaruh secara nyata terhadap kadar klorofil, kadar Zn total, serta uji warna pada sampel pasta pandan yang dihasilkan. Sampel terbaik diketahui sampel dengan perlakuan penambahan konsentrasi ZnCl2 1000 ppm dan penggunaan bahan pengisi berupa gum arab 20% (2:0) yang memiliki kadar klorofil sebesar 237,27 mg/g klorofil, dan kadar Zn total sebesar 173,19 mg/g. Dari hasil penelitian menunjukkan bahwa penggunaan ZnCl2 1000 ppm dan bahan pengisi berupa gum arab dapat menghasilkan pasta pandan dengan kualitas yang baik.

Purpose. To substantiate the components of monitoring of resource-saving regulation of the water regime of river basins in the system of environmental safety of the southern regions of Ukraine on the basis of managed restoration of water resources and elements of the disturbed aquatic environment. Methodology. A complex of standardized methods of field, desk and laboratory research, as well as methods of statistical processing of experimental data using the method of central composite orthogonal planning was used. Findings. The paper analyzes the trends in the water cycle in technological complexes and agricultural complexes with the subsequent use of local measures to condition the resource in order to recharge the water supply source. The modes of operation of technological equipment using process and recycled water in traditional and energy-saving modes were modeled. Schemes of recycled water purification for use in the technology park were developed to reduce the cost of the production product. A study of drought processes in the agricultural sector in the southern region was carried out to reduce the risks of water management with renewable resources. Experiments on the absorption of various types of anthropogenic mixtures through porous artificial and soil structures were performed in the field, followed by the determination of background concentrations of pollutants. Originality. During field and laboratory studies, applied tools for regulating the nutrition of water basins were developed. For the first time, a system for identifying agronomic drought phenomena and selecting priority measures to minimize the impact of moisture deficit in the context of global warming on the regional economy was designed. Greening of recreational areas of technology parks for the separation of sediment during gray water restoration was carried out. Recommendations were developed to regulate the operation of water management areas of enterprises in conditions of fluctuation in the flow of recycled water and other auxiliary economic needs to increase the water use coefficient of cities. Methods of wastewater treatment for the formation of components of water basin recharge were systematized. To improve the aquatic environment, a number of water protection concepts and programs have been developed, such as supply management, demand management, and integrated water resources management and environmental safety measures. Practical value. A system of combined nutrition of the water regime of the reservoir basin has been developed. Methodologies for the recovery of recycled water from municipal and industrial enterprises for reservoir nutrition were calculated and tested. Operating modes of the cavitation unit for surface water recovery were established. The directions of development of the water basin in the context of global warming and the anthropogenic load of cities have been developed.

Published: June 2024

Purpose. To develop an environmentally friendly technology for drilling and blasting operations in quarries that will ensure effective degassing and dust suppression during mass explosions by using a natural humate reagent in internal and external hydro-filling. Methodology. The study used a set of research methods: analytical – to establish the main technical and economic indicators that affect the cost of drilling and blasting operations; technical and economic analysis – to establish the relationship between the cost of operations, air pollution after massive explosions and types of hydro-fillings and concentrations of humate reagent. Findings. The paper presents the results of pilot tests of the effectiveness of applying the humate reagent in the preliminary humidification of blocks and its use in internal and external hydro-filling, which leads to a significant reduction in dust formation and degassing of mass explosions. During the period of production research from 2017 to 2021, the environmental efficiency of the use of internal and external hydro-filling with the use of humate reagent TU U 20.5-43384697-001:2020 was confirmed at the enterprises of the Metinvest Holding: PJSC Inhulets Mining and Processing Plant, Pivnichnyi Mining and Processing Plant, Tsentralnyi Mining and Processing Plant, as well as ArcelorMittal Kryvyi Rih, JSC Pivdennyi Mining and Processing Plant and Rudomain LLC. When using an aqueous solution of humate reagent with a concentration of 3 % in internal and external hydro-filling, the environmental effect involves on average: dust suppression – 54 %; neutralization of carbon monoxide – 62 %; neutralization of nitrogen oxides – 55 %. The results of industrial tests have confirmed scientific hypotheses regarding the processes of binding dust particles in the dust and gas cloud, as well as the effect of neutralizing explosive gases. Originality. Dependences of the concentration of humate reagent in internal and external hydro-filling and binding of dust particles during mass explosions with environmental efficiency in terms of dust and gas suppression were established. Industrial research will allow confirming the scientific hypothesis about the neutralization of CO by a humate reagent in mass explosions, which is based on the Langmuir theory. Practical value. An eco-oriented technology of drilling and blasting operations in quarries has been developed which is based on using humate reagents in internal and external hydro-filling and allows industrial enterprises using massive explosions to reduce dust, carbon and nitrogen oxide emissions.

Purpose. Development of a new approach to improving the accuracy of orientation based on radar reflections from local objects and a digital terrain model. Methodology. The research is based on the theory of radiation, reflection and reception of radar signals. Statistical analysis of a large volume of recorded signals establishes causal relationships between the appearance of “false” reflections formed by the back lobe of the radiation pattern and to develop a computational algorithm for their suppression. Findings. A method and software that allows detecting and suppressing “false” reflections formed by the rear lobe of the antenna pattern without distorting the reflections created by the main lobe. For this purpose, a criterion has been developed, determined by the ratio of the amplitude of the signal received by the front lobe to the amplitude of the signal recorded by the rear lobe. The criterion allows eliminating the “false” signals without having a priori information about the real radiation pattern using a regulator for the reduction of phantom reflections to an average noise level. Originality. For the first time, suppression has been carried out of “false” reflections without having a priori information about the real radiation pattern of the radar station antenna, as well as elimination of the loss of informativeness of the real reflection formed by the main lobe. Practical value. A method is suggested of radar immunity of radar stations is noise immunity due to “false” reflections. The potential of the method and the capabilities of the developed computer program determines the relevance of their capabilities for use by all radar stations at various frequencies, azimuths, ranges and terrain features.

Published: June 2024

In this study, we evaluated the neurophysiologic examinations of elderly patients admitted to our electroneuromyography (ENMG) laboratory to examine whether neuromuscular diseases vary with age as in many other diseases. ENMG examinations of 215 patients aged 65 years and older who applied to our ENMG laboratory in the last 3 years were retrospectively evaluated. Data of 79 males (36.7%) and 136 females (63.3%) with a mean age of 73.2±7.02 years were analyzed. The most common diagnoses in elderly patients were entrapment neuropathies (37.2%), followed by carpal tunnel syndrome. The other main pathologies were various peripheral nerve lesions (15.8%), polyneuropathy (14.9%) and radiculopathy (13%). Electrodiagnostic examinations were normal in 16.4% of the cases. In our patients over 65 years of age, the most common electrodiagnostic diagnosis of carpal tunnel syndrome was bilateral (74.6%). Diabetes mellitus was diagnosed in a significant proportion of patients with polyneuropathy. The rate of chemotherapy-induced polyneuropathy was also remarkable. Sciatic nerve damage was the most common peripheral nerve lesion. It is thought-provoking that these rates are still observed even though it is a well-known injection complication and despite all precautions taken. Early diagnosis of neuromuscular diseases and timely initiation of treatment are very important for prognosis. Electrodiagnostic examinations have a valuable role in the diagnosis and follow-up of these diseases. These diseases should not be ignored in the elderly population and the importance of early diagnosis and treatment should always be considered.

Objective: Premature Ejaculation (PE) is a common sexual disorder that considerably affects sexual satisfaction, subjective well-being, and quality of life. A clear picture of the pathophysiology of PE has still not been determined. Current research has revealed the involvement of the central nervous system. Alterations in frontal cerebral structures and a discrepancy between the reported and objectively measured intravaginal ejaculatory latency times both point to a possible alteration of time perception. The present study aimed to assess the time perception between individuals with lifelong PE and healthy individuals. Material and Methods: 24 individuals with lifelong PE and 24 healthy volunteers were recruited. Participants were administered both clinical measures and a time perception test battery including time interval estimation tests and time interval production tests for 4,7,32 and 58-second time intervals. Results: Lower predictions for 4-second time intervals were found in individuals with lifelong PE than in healthy controls. No differences were found for 7,32 and 58-second time intervals. The Premature Ejaculation Diagnostic Tool scores correlated negatively with the 4-second and 32-second time interval predictions. Conclusion: The present results indicate a time perception deficit for short intervals in individuals with lifelong PE for the first time. This might be due to a working memory/executive function deficit or disruption of frontal functions on account of impulsivity. A specific deficit in time perception deficit might also occur. Further studies assessing other frontal functions concomitantly are required to draw firm conclusions.
