Published: July 2022

Per and Poly-fluoroalkyl Substances (PFAS) has been a major subject of research in environmental sector ever since it was found in the environment and blood serums at toxic levels. As landfills are the final disposal method for majority of the waste, PFAS concentration in landfill leachate have been found in the range of few µg/L to mg/L. Only few conventional treatments such as Activated Carbon, Reverse Osmosis, and Ion-Exchange has been proven effective in removing PFAS. However, these treatment methods are proving to be very expensive and generate secondary contamination that needs to be disposed-off or treated. Since the phase out of C8-PFAS compounds, more short chain PFAS compounds are detected in landfill leachate. Hence, an effective treatment strategy is needed to keep up with the rising concentration levels and variety of PFAS compounds. The purpose of this study was to develop a sustainable and cost-effective process using modified Coal Fly-Ash (CFA) that can treat both short chain and long chain PFAS compounds. Previous studies have shown application of CFA in removal of dye and metals from different types of wastewaters. In previous studies CFA was modified to enhance its surface properties, that can improve the adsorption of organic and anionic contaminants. In this study, thermo-chemical modification was used on CFA to remove organic matter and PFAS compounds. Preliminary results showed that, CFA can remove more than 90% UV absorbance, more than 80% TOC and approximately 40% of total PFAS compounds. The maximum adsorption capacity for total PFAS was found to be 84 ng PFAS per g CFA, out of which 70 ng was for short chain PFAS and 14 ng for long chain PFAS compounds. An effective removal of organic matter and PFAS compounds, show a promising application of CFA in leachate treatment. However, further research is needed to analyze the adsorption dynamics, kinetics, post-treatment disposal method, and any possible contamination when mixing CFA with landfill leachate.

Defining Quality in Early Childhood Care and Education in Lebanon. (c2020)
Authors:   ,   Lebanese American University, Marji Lama
Published: July 2022

A nation’s licensing criteria and regulations are the most basic of policies that ensure children’s safety (Gormley, 1997); when these regulations are being met, a level of quality at the very least is being maintained. Thus, given the proportion of children who spend significant portions of their day in settings outside their immediate family context, it may be fairly accurate to say that the main aim of public regulation of childcare centres is to ensure that children's rights are respected and their safety and well-being is maintained as a priority in their daily experience at the childcare center. Considering this value given to quality in early childcare settings, the following study explores the meaning that policymakers and other stakeholders give to quality in Early Childhood Education and Care (ECEC) in Lebanon. The question is “how is quality defined by the Ministry of Public Health (MoPH) and other stakeholders as seen through the licensing requirements for childcare centres in Lebanon. The study is explored through a series of semi-structured interviews and through document analysis of the licensing policy provided by the Ministry of Public Health in Lebanon. The data could possibly serve as an evidence based document about the quality of early childcare centres, that could also potentially activate a discussion about quality of education for the years 0 to 3.

Feminist Research Ethics and Student Privacy in the Age of AI
Authors: Weinberg Lindsay
Published: July 2022

This article examines university researchers’ capture of student images on US college campuses for training facial recognition technology, and situates this project within universities’ broader historical alignment with militarism and racial injustice. It argues that feminist STS ethics provides a framework for not only challenging the ways that university research inquiry actively contributes to oppressive power structures, but also for reimagining university research ethics for a greater engagement with questions of justice. The article identifies the limitations of dominant institutional ethics and privacy rights discourses for centering justice considerations, and instead outlines an intersectional feminist approach to university research ethics that reimagines the relationship between research processes, power, and social impacts.

Published: July 2022

In the aviation sector, where intense rules and competition prevail, safe flight operations are possible with the employment of qualified human resources who can adapt to technology. The aim of this research is to investigate how the most suitable candidate can be recruited by evaluating many criteria together in the pilot recruitment processes, which are of critical importance for aviation enterprises. In this context, the opinions of senior pilots working in the world's top 10 airline organizations were consulted in the study carried out with the Analytical Hierarchy Process (AHP), which is one of the multi-criteria decision support methods. As a result of the literature research, the recruitment criteria for pilot candidates, which are actively used in the sector, have been listed in the context of the suggestions of experienced captains who also take part in various management positions in the aviation sector. A total of 17 criteria, 3 of which are upper and 14 are sub-criteria determined were weighted with the AHP method. As a result of the analysis, "technical", "non-technical" and "occupational criteria" were listed as the upper criteria according to the degree of importance in terms of local weights.
Potentials of Balanite Endocarp Pod Ash as a Cement Replacement Material
Authors: Waziri Hassan , Olubajo Olumide
Published: July 2022

The exponential growth of agricultural wastes such as Balanite seed pod has resulted in waste management issues and finding alternatives through waste recycling is an interesting area of research. Balanite seed pods were collected in Yobe state, washed, dried, crushed. Balanite endocarp pod ash (BEPA) was calcined at 600 °C for 3 hours in a muffle furnace and the biomass was characterized with X-ray fluorescence spectrometer to determine its chemical composition. The analysis showed that the ash composed of silica, alumina and ferric oxide (74.24 wt.%) indicated a strong pozzolan based on American Standard. The BEPA possessed a high loss on ignition of 8.24 wt.% owing to the presence of unburnt carbon in the ash. The ash obtained was sieved with 75 µm sieve and cement was replaced with ash between 2.5 wt.% ~ 12.5 wt.% at interval of 2.5 wt.% to assess its impact on cement properties such as setting time, consistence, mortar strength and water absorption. Results showed that as percentage replacement increases, the water absorption increased while the mortar strength diminished whereas as the curing days progressed its strength improved despite clinker diminution due to cement hydration. 60 days strength for below 10 wt.% BEPA cement blend produced enhanced strength compared with control which is evidence of slow pozzolanic reactions. The optimum percentage replacement with BEPA was obtained at 7.5 wt.% replacement beyond which significantly affected the cement properties especially its strength. It could be agreed that BEPA has potentials to be considered and employed as a cement replacement material.

Published: July 2022

The purpose of this study is to assess the impact of low-frequency electromagnetic fields (LF-EMFs = 0.5 MHz) on the phenotypic and genotypic levels concerning the antibiotic resistance, antimicrobial-resistant (AMR) genes, and resistance mechanisms of Pseudomonas aeruginosa (P. aeruginosa). In this study, the bacterial isolates were exposed to 0.5 MHz and then inoculated to a new medium for the assessment of their antibiotic sensitivity. The results showed that there were statistically significant changes in the antibiotic sensitivity upon exposure to extremely low-frequency waves along with significant changes in the antimicrobial genes and resistance mechanisms. We conclude that extremely LF-EMFs appeared to be effective in changing the antibiotic sensitivity and could be considered a future promising method for controlling bacterial resistance.

Published: July 2022

This study investigates phytochemical composition and the antimicrobial activities of aqueous and ethanol extracts of soursop (Annona muricata) leaves against some selected bacterial pathogens. Susceptibility effects of these extracts were determined by disc diffusion method against Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Streptococcus pyogenes and Staphylococcus aureus. The results showed that the efficacy of the aqueous extracts was more pronounced against the test bacterial, especially P. aeruginosa at minimum inhibitory concentration (MIC) of 0.2 mg/mL. The ethanol extract was more pronounced again S. pyogenes with diameter of zones of inhibition ranging from 15.00 – 32.00 mm at concentrations of 0.2 – 0.8 mg/mL respectively. The pathogens were susceptible to the aqueous extracts of the leave at concentrations between 0.4 – 0.8 mg/mL. Phytochemical compounds such as tannins, saponins, terpenoids, alkaloids, glycosides, and phenols were detected in A. muricata leaf extract. The significant antimicrobial properties of the leaf extract could be attributed to the presence of these bioactive compounds. Thus, this investigation proves to an extent that the Soursop leaf extracts when used against microorganisms, has sufficient antimicrobial property.

Discussions in the TGNA on The Law of The Command in Director
Authors: ORTAK Şaban
Published: July 2022

Absract: In order to meet the needs of the army and to lead the war, the Turkish Grand National Assembly (TGNA) adopted the “Law of the Commander-in-Chief” on 5 August 1921. With this law, the TGNA gave some of its powers to Mustafa Kemal Pasha for a period of three months. Mustafa Kemal Pasha, who published the "Tekalif-i Milliye Emirleri: National obligation orders " based on this authority, prepared the army for war. In this way, the Battle of Sakarya was won and the Greek attack was repelled. With the effect of this victory, the first two extensions of the Commander-in-Chief Law were accepted without any discussion in the TGNA. However, as a result of the grouping in the TGNA, the issue of extending the term of the Commander-in-Chief for the third time caused long discussions in the Assembly. In the voting held on 4-6 May 1922, the extension of the deadline was accepted with difficulty. The issue of the fourth extension of the period was brought to the agenda at the meeting of the Assembly on 20 July 1922. Mustafa Kemal Pasha stated that the army was in good condition and stated that there was no need for the extraordinary authorizations given to the Commander-in-Chief. In the negotiations, it was accepted that the TGNA would assign Mustafa Kemal Pasha as the Commander-in-Chief, with a "temporary" condition and without specifying the time period. The War of Independence ended with the victory of the administration of the Commander-in-Chief. In the article, the reasons for the adoption of the Law on the Commander-in-Chief, the adoption of the law and the subsequent time extension will be discussed in detail. TGNA Parliamentary Minutes, TGNA Secret Session Minutes, archive documents, memoirs and other research works will be used. The research is based on a descriptive survey model. In this study, document analysis method was used.

The purpose of this study is to analyze the impact of Covid-19 in the Rupiah Exchange Rate on the United States Dollar and the Composite Stock Price Index in Indonesia. The data used are primary and secondary data: the Rupiah Exchange Rate and the CSPI value taken for 66 days starting from October 2019 to March 2020. The data were analyzed descriptively by explaining the impact caused by Covid-19. The results found that the Covid-19 Pandemic harmed the economy both the Rupiah Exchange Rate against the US Dollar and the movement of the Composite Stock Price Index in Indonesia. The findings found that before the Covid-19 Pandemic the value of the Rupiah against the US Dollar and the movement of the Composite Stock Price Index experienced negative sentiment while after the Covid-19 pandemic it moved negatively due to negative sentiment from market participants who were still focused on the spread of the Covid-19 pandemic in Indonesia, as well as many market players who still sell shares because of global panic. Nevertheless, the Indonesian government has anticipated the economic downturn in Indonesia by implementing fiscal policies, to reduce the negative impact of the Covid-19 pandemic.

Sebagai bentuk upaya mitigasi, para pelaku UKM dapat menggunakan PAMAN KAMI, termasuk diantaranya adalah unit-unit usaha yang ada di lingkungan Universitas XYZ, yaitu PT A, Koperasi B, dan Penerbitan C. Ketiga unit tersebut dapat menggunakan PAMAN KAMI karena dua alasan. Pertama, belum pernah memeriksa status keamanan informasi usahanya. Kedua, tidak memiliki server atau peralatan jaringan yang rumit dan tidak ada aplikasi yang dikembangkan secara mandiri atau hanya menggunakan aplikasi dari pihak ketiga. Tujuan penelitian ini adalah untuk mengidentifikasi sejauh mana level keamanan informasi pada PT “A”, Koperasi “B”, dan Penerbit “C”. Teknik pengambilan sampel yang digunakan pada penelitian ini ialah pengambilan sampel berdasarkan pertimbangan tertentu (judgement sampling). Teknik pengumpulan data yang digunakan dalam penelitian ini, yaitu kuesioner dan wawancara. Hasil dari penilaian menunjukkan bahwasanya ketiganya masih di bawah kategori cukup. Hal ini disebabkan karena fokus ketiganya masih bersifat operasional dan belum berfokus ke arah strategis (seperti keamanan informasi).

Published: July 2022

Soil erosion disaster is a disaster that occurs simultaneously with landslide events that occur due to the destruction of the soil layer which then causes erosion followed by landslides. The phenomenon of land erosion occurs due to high rainfall, the influence of slopes and slope length, as well as due to development resources according to Mamarodia (2014). Erosion can also occur due to land degradation, namely the loss of organic matter and nutrients from the root area, this study aims to determine the erosion hazard model in Batam Island which can be displayed in the form of a RUSLE model by utilizing a geographic information system (GIS). The data used in the form of slope maps, land use maps, maps of soil types and rainfall maps on Batam Island using the data processing method used is the RUSLE method to provide information in the form of erosion hazard categories and produce a two-dimensional erosion hazard model map. The result is a map of the erosion hazard model in a two-dimensional form with categories obtained from the combination of the four maps that have been classified. The results of this research are information on the area of ​​soil erosion with very light categories (24,200.42 Ha), light (5,488, 20 Ha), medium (5,100.42 Ha), heavy (3,029.43 Ha), and very heavy (2,929.64 ha) spread over Batam Island. The slope with the highest slope height is class 129,284 ft to 148,627 ft, and the lowest height elevation is in class -6,11 ft to 13,232 ft. the Batam area tends to have an area with an elevation of 13,232 ft to an altitude of 32,574 ft.
THE INFLUENCE OF FINANCIAL LITERACY ON INTENTIONS TO INCREASE THE PERFORMANCE AND SUSTAINABILITY OF MSMEs DURING THE COVID-19 PANDEMIC IN BULUKUMBA
Authors: Rasjid Rani Dian Aryani
Published: July 2022

This study aimed at analyzing the effect of financial literacy on intentions to improve the performance and sustainability of MSMEs specifically engaged in the culinary and handicraft industries during the COVID-19 pandemic in Bulukumba, South Sulawesi, Indonesia. The population of this study was MSMEs engaged in the culinary and handicraft industries and registered at the Department of Cooperatives and MSMEs (Indonesian: Dinas Koperasi dan UMKM) of Bulukumba. The employed technique of data analysis was a structural equation modeling-partial least square (SEM-PLS) using SmartPLS 3.0 software. In this study, the researchers utilized the Theory of Planned Behavior to determine intentions to improve the performance and sustainability of MSMEs. Results indicated that financial literacy has an effect on intentions (attitude toward behavior, perceived behavioral control, and subjective norm). Furthermore, the researchers found strong intentions (attitude toward behavior and perceived behavioral control) within MSME actors, resulting in attitudes for improving the performance and sustainability of MSMEs in Bulukumba. However, the intention specifically on the variable of the subjective norm has no effect on the performance and sustainability of MSMEs. Knowledge sharing to MSMEs occurs not only from the government, academicians, or big businesses but also between MSMEs, which can be the main key to the success of MSMEs in the era of global trade. Furthermore, it is important to realize that intra-MSME cooperation is highly needed to achieve complementary capabilities.
